Математическая модель светозависимого содержания пигментов в микроводорослях.
Provedor de dados: 13
Autores: Тренкеншу, Р. П.; Геворгиз, Р. Г.
Предложен механизм, объясняющий зависимость содержания клеточных пигментов от интенсивности света в растениях. Основой механизма является представление о двух процессах определяющих концентрацию пигментов в клетке: синтез и разрушение пигментов под действием света. Разработана математическая модель зависимости содержания пигментов в биомассе микроводорослей от интенсивности света. Получены уравнения, которые позволяют сделать оценку количества квантов света необходимых для разрушения пигментов (одно-,двух- или многоквантовый механизм). http://biotex.ibss.org.ua/

BR-5133 (MILHACRE): milho precoce para cultivo no Estado do Acre.
Provedor de dados: 14
Autores: CAMPOS, I. S.; COSTA, J. G. da; FAZOLIN, M.; LODI, N. V.
A época de plantio de milho no Estado do Acre concentra-se da segunda quinzena de setembro ao final de outubro, período de início das chuvas. A precipitação pluviométrica anual situa-se e, torno de 2000mm, distribuída de outubro a maio. No Acre, embora em pequena escala, os produtores praticam um segundo cultivo de março a julho, sem necessidade de irrigação suplementar. Este plantio, se efetuado com base técnica e material genético melhorado, adaptado às condições edafoclimáticas locais, propiciará vantagens tão consideráveis para os agricultores, que resultará na intensificação do cultivo do milho nessa época e, consequentemente, aumento da produção do Estado.

O extenso territorio brasileiro, caracterizado por variadas condicoes climaticas e por distintos tipos de solos, apresenta uma producao agricola extremamente diversificada, que confere ao pais o titulo de principal produtor mundial de varios produtos. A fruticultura, nao obstante representar apenas 5% das areas cultivadas no pais, e uma das atividades capazes de assegurar ao Brasil um percentual significativo do volume de producao global, colocando-se em primeiro lugar no ranking dos produtores de frutas (FAO, 1992 e Carraro &amp; Cunha, 1994). Apesar da importancia do setor para o pais, nao existe paralelismo entre aumento da producao e avanco de tecnologias de pos-colheita capazes de minimizar as perdas.

Provedor de dados: 14
Autores: SAUERESSIG, T. M.
Tick fever is a general name for a disease caused by both or either haemoparasites Babesia and Anaplasma. Cattle tick Boophilus microplus is the vector of the disease although anaplasmosis can also be transmitted by blood sucking insects. In most regions of Brazil, B. microplus can occur throughout the year because of suitable climate conditions. In the brazilian savannah region there are two or three cattle tick generations per year with a infestation peak in october. The increasing use of cultivated pastures and crosses with tick-susceptible european breeds has decreased resistance of zebu cattle in this region and control measures are suggested. Total control of B. microplus, howecer, can decrease cattle imunity and favours the occurence of tick fever....

Autores: FUKUDA, W. M. G.
Variedade de mandioca e um dos principais componentes para o desenvolvimento do sistema produtivo dessa cultura, alem de constituir uma tecnologia que nao implica em custos adicionais para o produtor. Apesar da mandioca apresentar um alto potencial produtivo, estimado por COCK (1974) em 90 t/ha/ano, a produtividade nacional esta em torno de 12 t/ha. Um dos fatores que tem contribuido para a baixa produtividade desse cultivo no Brasil, e o uso de variedades com baixo potencial produtivo. A demanda por novas variedades de mandioca vem crescendo constantemente, a medida que surgem novas alternativas de uso pelo produto, bem como a expansao de novas fronteiras agricolas para o plantio dessa cultura. Para atender essas demandas, e importante definir-se as...

Provedor de dados: 14
Autores: GALDINO, S.; CLARKE, R. T.
O nivel hidrometrico do rio Paraguai em Ladario, MS, medido pela regua instalada no 6. Distrito Naval da Marinha do Brasil, constitui o principal referencial do regime hidrologico da bacia do Alto Paraguai, possibilitando ate mesmo a caracterizacao de um dado periodo como sendo de seca ou de cheia no Pantanal. Quando o nivel maximo anual (pico ou ponta de cheia) e igual ou superior a cota de alerta de enchente do rio Paraguai em Ladario, ou seja 4,00 m, esse ano e considerado como sendo de cheia no Pantanal, caso contrario, como sendo de seca. Utilizando-se 34.607 registros diarios, relativos ao periodo de 01/01/1900 a 30/09/1994, foram realizados levantamentos e estudos estatisticos a nivel; diario, mensal e anual (ano hidrologico).

Recomendações para produção, plantio e manutenção de mudas de cajueiro.
Provedor de dados: 14
Autores: CARBAJAL, A. C. R.; SÁ, F. T. de; FRANCO, F. G. S.
O CNPAT não recomenda a utilização da castanha na implantação de pomares de caju porque as plantas obtidas serão diferentes entre si no que se refere a altura da planta, tamanho, forma e paladar do pedúnculo e da castanha, períodos de floração, frutificação e colheita, colaração do pedúnculo, produção de castanha e de pedúnculo. Esta viabilidade (heterogeneidade) não e conveniente para o agricultor porque, além de dificultar o manejo do pomar (capinas, rocagem, adubação, controle fitossanitário e colheita), a produção de pedúnculo e da castanha é afetada negativamente em função da presença de plantas pouco produtivas e improdutivas.

O emprego da irrigacao na fruticultura nordestina vem experimentando um razoavel incremento, especialmente nos produtos tradicionalmente destinados ao mercado externo, motivado pelos resultados que propicia, com destaque para o incremento da produtividade, melhoria da qualidade dos frutos e possibilidade de producao fora da epoca de maior oferta (CODEVASF, 1989). Infelismente este incremento nao tem sido acompanhado do correspondente avanco tecnologico, como pode ser observado em algumas especies frutiferas de interesse agroindustrial, que ainda nao dispoem de informacoes que possibilitem sua exploracao economica, principalmente sobre condicoes irrigadas.

O composto orgânico utilizado como fertilizante é um produto estável, resultante da decomposição bioquímica controlada, de uma mistura de diferentes resíduos orgânicos. Esta mistura deve ter como característica principal a relação carbono/nitrogênio (C/N) em torno de 30, pois os microrganismos necessitam de 30 partes por peso de carbono para cada parte de nitrogênio consumida. Neste trabalho são relatadas não só a importância e constituição do composto orgânico, mas também as diversas técnicas empregadas para o seu preparo e aplicação.

Efeito da densidade de semeadura sobre características da planta de girassol.
Provedor de dados: 14
Autores: BEVITORI, R.; ANTAL, J. B.
No Estado de Goiás, o girassol foi introduzido simultaneamente com o estabelecimento da primeira indústria de extração mecânica de óleo de girassol. Em 1993, o seu cultivo representou uma área de mil hectares, que foi ampliada quase cinco vezes no ano seguinte. O girassol, plantado principalmente nas áreas de sequeiro, representa uma nova opção para o agricultor goiano na época da safrinha. Nessa época, o fator limitante da produção e a falta de água que ocorre, frequentemente, por ocasião do florescimento e enchimento dos aquenios. Para minimizar a queda de rendimento, ocasionada pela deficiência hídrica, devem-se escolher a época de semeadura e a população de plantas mais apropriadas as condições edafoclimáticas locais.

Os cavalos introduzidos no Pantanal pelos conquistadores durante a epoca da colonizacao, encontraram na regiao condicoes ambientais propicias para sua multiplicacao. Como consequencia dos processos adaptativos e da selecao natural por mais de dois seculos e com pouca ou nenhuma interferencia antropica, surgiu um tipo adaptado ao meio. Com o desenvolvimento da pecuaria na regiao, o cavalo Pantaneiro constituiu-se num fator de importancia economica e social, tornando-se imprescindivel em trabalhos de gado e no transporte regional. No final do seculo XIX, a raca entrou em declinio principalmente devido a doenca conhecida como Peste das cadeiras e, posteriormente, outras ameacas como cruzamentos indiscriminados com outras racas e, mais recentemente a Anemia...

Estudo do efeito do deficit fenologico da agua sobre a producao e caracteristicas industriais do tomate, variedade Rossol VNF, com oito tratamentos e tres repeticoes. Os deficits de agua foram provocados em determinados periodos do ciclo fenologico da cultura. O solo foi mantido com condicoes otimas de umidade antes e depois dos periodos de deficit de agua. As producoes comerciaveis apresentaram diferenca significativa entre os tratamentos, ao nivel de 5% de probabilidade. As fases de inicio de frutificacao e desenvolvimento dos primeiros frutos caracterizaram-se como as fases mais criticas da cultura ao deficit de agua apresentando reducao nos rendimentos da ordem de 61,9 e 59,8% respectivamente. Os teores de solido soluveis e de acidez nao foram...

A ecologia.
Provedor de dados: 14
Autores: MIRANDA, E. E. de.
Este livro apresenta de maneira simples os principais temas e problemas tratados pela ecologia nos dias de hoje, evitando gráficos, fórmulas matemáticas, esquemas e - na medida do possível - termos especializados. Esta publicação não busca substituir os livros básicos de ecologia, nem os inúmeros trabalhos existentes sobre cada um dos assuntos abordados. Sem pretender esgotar um assunto tão complexo, as cinquenta palavra apresentadas abordam as principais questões, conceitos e fenômenos tratados pela ciência ecológica. Mas uma lista de 300 palavras, no final do livro, permite ao leitor completar sua informação e esclarecer dúvidas, dada a organicidade efetiva existente entre muitos dos termos apresentados.

Recomendação de cultivares de abacaxi para produção de mudas por secção de caule nas condições climáticas de Rio Branco - Acre.
Provedor de dados: 14
Autores: LEDO, A. da S.; MEDEIROS, J. A.; AZEVEDO, F. F. de.
Dentre as frutíferas de importância econômica no Estado do Acre, se destaca o abacaxi devido a sua boa produção e a sua demanda na alimentação regional. Tem-se observado a expansão da cultura principalmente como componente temporário de sistemas de produção consorciados com fruteiras e outras culturas regionais. O Centro de Pesquisa Agroflorestal do Acre desenvolveu estudos sobre o comportamento de cinco cultivares de abacaxi quanto à propagação vegetativa por secção do caule, conforme metodologia proposta por Reinhardt &amp; Cunha (1989).

E analisada a biologia do curimbata (P. lineatus), do pintado (P. corruscans) e da cachara (P. fasciatum) na bacia hidrografia do rio Miranda. Estas especies realizam migracoes ascendentes para reproducao a partir de setembro-outubro. A desova, do tipo total, ocorre nos cursos superiores dos rios Miranda e Aquidauna, principalmente de dezembro a fevereiro. Apos a desova, retornam aos cursos inferiores, onde se espalham pelas areas alagadas, alimentando-se fartamente. Este padrao de migracao esta ligado ao ciclo fluviometrico desses rios. P. lineatus e uma especie detritivora, enquanto P. corruscans e P. fasciatum sao ictiofagas generalistas. Jovens e adultos apresentam distribuicao diferenciada. O crescimento dessas especies e analisado.

Geração de tecnologia para o setor agrícola.
Provedor de dados: 14
Autores: PEIXOTO, S. E.
O processo de geração de tecnologia tem como objetivo principal a obtenção e incorporação de novos conhecimentos ao sistema produtivo, visando a elevação dos índices de produção e de produtividade das atividades agropecuárias. Este processo assume suas características atuais a partir do século XVII quando a geração de conhecimentos desloca-se das mãos dos produtores rurais para as dos cientistas, passando, por conseguinte, a ter uma base urbana. Descobertas dessa época, como as sementes melhoradas, adubação, pastagens artificiais e armazenagem em silos, possibilitaram um acentuado aumento da produção e da produtividade, que associado a outros fatores, contribui para a viabilização da Revolução Industrial.

Influencia da fase de maturacao da castanha na infestacao da traça, Anacampsis sp.
Provedor de dados: 14
Autores: BLEICHER, E.; ABREU, A. R. M.; MELO, Q. M. S.
Neste trabalho verificou-se a influencia da idade da castanha, segundosua cor, na infestacao da traca da castanha, Anacampsis sp. O experimento realizou-se no segundo semestre de 1991, em cajueiro, Anacardium occidentale L.; com os clones CCP 76, CCP 1001 e CCP 09. A infestacao da praga foi medida pela observacao direta do sinal de dano em 100 a 200 castanhas por amostras e expressa em percentagem. Observou-se que a traca das castanhas inicia o ataque em castanhas de cor vermelha e aumenta sua intensidade a medida que o fruto se desenvolve.

Características da pequena produção agrícola no Nordeste.
Provedor de dados: 14
Autores: PEIXOTO, S. E.
A pequena produção agrícola tem-se constituído ultimamente em um dos temas de maior interesse, tanto dos estudiosos das ciências sociais e agrárias como das autoridades governamentais. Tal preocupação decorre do reconhecimento da importância desta forma de produção no conjunto da economia e que se expressa na participação da oferta de alimentos e matérias-primas agrícolas, quando se considere a concentração de grande parte da população nos centros urbanos, a evolução do processo inflacionário etc. Por outro lado, reconhece-se que as condições de trabalho e de vida da maioria dos pequenos produtores são ainda bastante precárias, tornando-os vulneráveis as adversidades do meio em que vivem e produzem. Destacam-se, neste particular, o problema da posse e dos...

Autores: BARROS, A. T. M. de.
O Pantanal representa uma das regiões mais importantes do pais em termos de Pecuária de corte, com um rebanho estimado em cerca de 3,8 milhões de cabeças (Cadavid Garcia, 1986). Desde sua chegada a região em 1991 (Barros, 1992), a mosca-dos-chifres (Haematobia irritans) tem gerado uma significativa apreensão a classe produtora. A ocorrência inicial de níveis de infestação considerados prejudiciais e a crescente demanda por um programa de controle evidenciaram a necessidade de estudos na região. Desde 1993, pesquisas vem sendo desenvolvidas visando definir as épocas, níveis e duracao das infestações nos bovinos, com o objetivo de avaliar a magnitude do problema e propor um programa de controle adequado ao Pantanal. Paralelamente, tendo em vista a...

Como climatizar bananas em pequenas propriedades.
Provedor de dados: 14
Autores: MEDINA, V. M.; SOUZA, J. da S.; SILVA, S. de O. e.
A banana, um fruto climatérico, pode ser colhida em vários graus de maturidade e induzida a madurecer com excelente qualidade. A indução em larga escala normalmente e feita usando-se os gases etileno e acetileno, os quais requerem instalações e equipamentos caros e sofisticados. Os pequenos produtores que não tem acesso a essa tecnologia podem optar pelo ethephon, cujo uso e mais simples e de menor custo. O presente trabalho contem orientação para utilização do ethephon na climatização de bananas, com descrição das instalações e materiais necessários.

Analysis of shell colour determinism in the Manila clam Ruditapes philippinarum
Provedor de dados: 5
Autores: Peignon, Jean-marie; Gerard, Andre; Naciri, Yamama; Ledu, Christophe; Phelipot, Pascal.
The Manila clam presents a large polymorphism for shell colours and patterns. No experiment has been conducted to study the determinism of such a polymorphism which has been well known for a long time. The aim of this study was firstly to determine the genetic variation for shell colour and secondly to produce some homozygous lines for the shell colouring. These lines could then be used as controls for laboratory experiments. The colouring is defined by three characters: asymmetry, ornamentation and hue. Clams with asymmetrical colouring are not fully pigmented, except for a posterior band on the left valve. Clams with symmetrical colouring are fully pigmented on the two valves. Four cross series were conducted between the different characters: Asymmetry...

Monthly HPLC measurements of pigment concentration from an intertidal muddy sediment of Marennes-Oléron Bay, France
Provedor de dados: 5
Autores: Cariou-le Gall, Valerie; Blanchard, Gerard.
Chloropigments and carotenoids were measured by HPLC in an intertidal muddy sediment of Marennes-Oleron Bay (France). Concentrations were determined as a function of sediment depth at low tide. The analyses were carried out at monthly intervals over 1 yr. Pigment analysis indicated that the microphytobenthic community was dominated by diatoms throughout the sampling year. Chlorophyll b was not encountered at any time or depth, indicating that no input from macrophytic detritus had occurred at the sampling site. There was a large pool of phaeopigments a, of which phaeophorbides were the major forms (75%). A microphytobenthic bloom occurred between March and June during which phaeopigments significantly increased with a high proportion of phaeophorbides...

The SEMAPHORE mesoscale air/sea experiment was conducted in the Azores-Madeira region from July to November 1993. TOPEX/POSEIDON (T/P) and ERS 1 were flying simultaneously at that time. The main purposes of this paper are to evaluate the estimation of the oceanic mesoscale circulation from the two different sets of altimetric data (T/P and ERS 1) and to compare the results with in situ measurements provided by the SEMAPHORE hydrographic surveys and surface drifters (three expendable bathytermograph conductivity-temperature-depth surveys in a 500-km(2) box and a set of 47 Lagrangian surface drifters drogued at 150 m). Comparisons are carried out through the maps obtained by objective analysis from the four data sets. The mapping accuracy of T/P, ERS 1, T/P...

Fumage électrostatique : Application aux produits de la mer
Provedor de dados: 5
Autores: Knockaert, Camille.
The purpose of the study presented in this report is to demonstrate the feasibility of electrostatic smoking applied to fish and to present a pilot which will foreshadow an industrial model. If the idea of using high voltage to accelerate the depositing of smoke compounds goes back to the 1920's, its application to sea produce has still not become common practice. The essential reason for this comes from the fact that reducing smoking time restricts drying time by as much. A new salting/drying technique - Oewatering Impregnation Soaking (DIS) - means, that products with a requisite salt and water content can be smoked. Electrostatic smoking therefore allows processing time to be cut by more than twelve compared to the traditional method (herring and...

Effet des bungalows sur pilotis des hôtels en milieu corallien sur le peuplement ichtyologique
Provedor de dados: 5
Autores: Planes, S; Doherty, Pj.
Increasing tourism in French Polynesia has encouraged resort development, especially on three islands of the Society Archipelago (Bora-Bora, Moorea, Tahiti). Although different resort stuctures have been developed, in 1993 there were 17 hotels consisting of bungalows built on piles along the fringing reef, and this kind of construction is becoming increasingly popular. Our study was designed to estimate the impact of such buildings on the local fish communities. Visual surveys were conducted by two observers at four resorts, under three bungalows built on piles and three adjacent control sites. Overall fish diversity and abundance was higher under the bungalows, with average increases of 10 % and 100 % respectively. A multifactorial ANOVA showed that...

Benthic Boundary-Layer macrofauna from the upper continental-slope and the Cap-Ferret canyon (Bay of Biscay)
Provedor de dados: 5
Autores: Dauvin, Jc; Sorbe, Jc; Lorgere, Jc.
A new version of a hyperbenthic sledge with four superposed nets was used from 346 m to 3070 m depth in the southern part of the Bay of Biscay. This gear collects the near-bottom swimming macrofauna. The dominant zoological groups are asellot isopods and gammaridean amphipods. Two types of animal density gradient are observed: a vertically decreasing gradient from the lower to the upper level of the sledge at each station; and a depth-related decreasing gradient from the upper continental slope to the lowest stations in the Cap Ferret Canyon. Three different assemblages can be distinguished: between 346 m and 523 m on muddy sand; between 600 m and 1100 m on mud; and in Cap Ferret Canyon between 3040 m and 3070 m on mud. These results are compared with...

Economics and biology used in fisheries research or when social and natural sciences try to depict together the object of their research
Provedor de dados: 5
Autores: Catanzano, Joseph; Mesnil, Benoit.
Fisheries can be characterized as a network of interactions between natural and social systems, and thus should be viewed as complex, dynamic systems. Due to the multiplicity of components and processes, the involvement of various disciplines is required to understand the inter-relationships within and between the systems, and more so to adequately address management issues that typically affect several elements in the systems. To be successful, multidisciplinary approaches require mutual understanding of the perspectives, concepts, vocabulary and methods held by various disciplines, and agreement on the objects to be studied in common. In that spirit, at framework is suggested whereby fisheries systems are decomposed into related sub-systems that can be...

Étude sédimentologique et méiobenthos d'un écosystème lagunaire modifié par un récif artificiel à vocation aquacole : l'acadja
Provedor de dados: 5
Autores: Guiral, D; Gourbault, N; Helleouet, Mn.
In developing countries, recourse to extensive aquaculture systems based on the exploitation of natural aquatic food webs is currently the subject of considerable interest. In this connection, the construction of artificial reefs (known as Acadja) for the development on substrates of living communities, and the utilization of this new production to enhance fish growth have been evaluated in Cote d'Ivoire. This paper describes the granulometric, chemical and biological transformation of the sedimentary ecosystem as a consequence of this practice. In the artificial habitat, an increase in the sedimentation rate of the mineral fraction (definitive trapping of particle resuspension generated by the waves and induced by the wind) and of the organic fraction...

Approches bibliographique et expérimentale de méthodes permettant d'évaluer l'état de maturité sexuelle des bivalves
Provedor de dados: 5
Autores: Thielley, Maryse.
A l'heure actuelle, l'objectif des éc10series d'huîtres est d'atteindre une autonomie d'approvisionnement en larves quelle que soit la saison et donc d'étaler les émissions de gamètes sur toute l'année. A la suite de problèmes rencontrés pour atteindre cet objectif, il s'est avéré nécessaire d'entreprendre des études sur les méthodes à mettre en oeuvre pour contrôler la qualité de la reproduction en écloserie et notamment l'état de maturité des géniteurs. Notre étude porte sur ce dernier point. Une étude bibliographique présente les différentes méthodes plus ou moins précises, actuellement utilisées pour contrôler l'état de maturité des gonades de bivalves. La majorité d'entre elles nécessite le sacrifice d'animaux. Une approche expérimentale portant...

The distributions of inorganic nutrients and phytoplankton chlorophyll-a were investigated in relation to the hydrography of the Aegean Sea. The data were collected during cruises in May and October 1992, February, May and October 1993 and July 1994, in the framework of a National Marine Measurement and Monitoring Programme for the Aegean Sea. Concentrations of nitrate +nitrite+ammonia nitrogen and phosphate phosphorus were lower than those previously reported for the Black Sea; generally lowest at the surface, they increased with depth. The highest nutrient values were in the northern part of the Aegean Sea, and may have resulted from water originating from the Black Sea. Both phosphates and silicates increased with depth to maxima of 0.16 and 4.7 mu M,...

A study of the environmental factors in the "pertuis charentais" (charentais straits) has been carried out from 1993 tc 1994. The evolution of water temperature and salinity, as weil as the turbidity, are studied. ln the middle of Breton Strait, near to the long lines, the stratification has not been observed, and the salinity variations are much less sharp than in the stations which are located nearer the coast. The photosynthetic pigments concentrations can be very different in the same time at two close stations; in the Antioch Strait and at the long lines, the values of chlorophyll "a" are comparable; they are much higher in the Breton Strait. At the same time, a study has been made on the physical factors, the photosynthetic pigments concentrations,...

Nature et fonctionnement des atolls des Tuamotu (Polynésie Française)
Provedor de dados: 5
Autores: Rougerie, F.
The 77 atolls of the Tuamotu Archipelago (French Polynesia) constitute bio-geomorphological singularities in the oligotrophic oceanic field of the South Pacific. These open-ocean atoll reefs are locally overlaid by sandy islets (motu) and encompass lagoons with hydrological properties that are different from oceanic water, according to their degree of enclosure. Lagoonal waters may be more or less saline and eutrophic than oceanic water. In eutrophic lagoons, corals are replaced by macro-algae and cyanobacterial mats. At the archipelago scale, invariance in the geomorphologic patterns of the atoll reefs, despite diffences in age (1 to 50 million years) and in size (2 to 1600 km(2)) underline functional similarities which appear to be independent of surface...

Autores: Duquesne, S; Richard, A.
Two species of flatfish, Limanda Limanda (dab) and Microstomus kitt (lemon-dab) were injected intraperitoneally with Cd to determine the nature of the metal-binding proteins induced in their livers. The supernatants were analysed by gel filtration chromatography and the levels of metal and sulfhydryl groups, as well as the spectral behaviour of the low molecular weight proteins, provided evidence that the hepatic metal-binding proteins induced in the two flatfish belong to the family of metallothionein-like proteins.

Résultats du REMI (REseau de surveillance MIcrobiologique) du Traict de Pen Bé (Loire-Atlantique) à la pointe du Payré (Vendée). Année 1994
Provedor de dados: 5
Autores: IFREMER.
Le REMI est l'un des 3 réseaux de surveillance du milieu marin gérés par l'IFREMER. Il concerne la surveillance bactériologique des eaux littorales.  Historiquement, l'objectif principal de la surveillance bactériologique du milieu marin en France était la salubrité des bivalves pour la consommation humaine. En 1989, sa mission a été étendue à la surveillance de l'environnement. L'organisation actuelle du réseau répond à ces deux objectifs.  L'appréciation de la contamination bactériologique du milieu marin, et notamment des eaux conchylicoles, est basée sur la mesure des coliformes fécaux dans les coquillages. L'emploi de ces germes tests de contamination comme traceurs de pollution permet d'estimer l'importance de la "fécalisation" des eaux et donc les...

A hydrobiological study coupled with the evolution of the production of cupped oysters Crassostrea gigas has been carried out from March 1990 to March 1991 on two oyster culture areas (North and South) of the Bay of Bourgneuf. - The northern area is characterized by an environment which is variable though time and composed of a high nutritive and mineral load. This high particular load (average value = 154 mg.l- 1) is linked to meteorological conditions and especially to the wind speed and direction. The individual growth of cultivated oysters is low (i.e.: 58.8 g). - The southern area shows homogenous hydrobiological characteristics throughout the year. The average phytoplanktonic biomass is 4.4 µg.l-l of chlorophyll and the particular load is low...

Evaluation des proliferations d'algues vertes sur le littoral  breton en juin 1994
Provedor de dados: 5
Autores: Piriou, Jean-yves; Annezo, Jean-pierre.
During June 1994, 44 beaches with "green-tides" were identified along the coasts of Brittany. Compared to previous years, seaweed amounts accumulated on beaches receiving nitrogen inputs from granitic catchments can be considered stable, contrary to beaches exposed to nutrient fluxes originating from schistous catchments, where an increase of accumulations is observed. This late process can be explained by an increase of nitrogen loadings during periods of heavy rain (late spring 1994) on impervious basement rocks.

La France est le quatrième producteur mondial après les USA, le Japon et la Corée. Elle est de loin le premier producteur Européen d'huîtres avec 140 000 T/an. Le bassin de Marennes- Oléron produit annuellement environ 25 à 30 000 T, mais commercialise 60 à 65 000 T. Cette différence entre production et commercialisation est constituée par les apports d'autres bassins de production, lesquels sont affinés ensuite dans les claires de Marennes- Oléron. En 1993, le Département des Ressources Aquacoles de l'IFREMER a mis en place un réseau national (REMORA) de suivi de croissance et de production de l'huître creuse japonaise Crassostrea gigas qui permet de disposer d'une base objective de comparaison des différents bassins de production.

Horizontal variability of surface currents in the Dead Sea
Provedor de dados: 5
Autores: Essen, Hh; Gurgel, Kw; Schirmer, F; Sirkes, Z.
Surface currents in the Dead Sea, as measured by two land-based HF (high frequency) radar stations in autumn 1984, are analysed. High horizontal variability is observed, which may partly be explained by the inhomogeneous wind field. Decomposition into empirical orthogonal eigenfunctions (EOF) shows that the currents may not be represented by a small number of patterns. The forcing of currents by wind is proved through significant correlation between both. Spatially-averaged rotary spectra provide evidence of the presence of inertial oscillations. The data set allows the calculation of horizontal derivatives. Time series of divergence and curl are presented. By estimating the advective terms of the Navier-Stokes equation it is shown that nonlinear effects...

A numerical prediction of bed shear stresses in the wave-current turbulent boundary-layer over flat sea beds
Provedor de dados: 5
Autores: Huynhthanh, S; Temperville, A.
The turbulent boundary-layer flow over flat rough beds due to a wave or to combined wave-current interaction is studied using a numerical turbulence closure model of K-L type. Different cases of modelling are discussed and illustrated by numerical examples. The model was run for a wide range of parameters of wave, current, bed roughness and angle of interaction. The curves of dimensionless mean and maximum bed shear stresses obtained present the non-linearity of the wave-current interaction. The parameterization of results is realized in order to facilitate the incorporation of bed shear stresses into coastal morphodynamic models.

A model of the whole Mediterranean sea at 0.25 degrees x 0.25 degrees resolution has been run for ten years with a mean seasonal cycle of forcing using NMC winds and a relaxation to NODC surface temperature and salinity. The winter season water formation and dispersal in the model thermocline has been studied using isopycnal diagnostics and potential vorticity as a water mass tracer. In the eastern basin Levantine Intermediate Water (LIW) is formed in the cyclonic Rhodes gyre and moves west in a continuous mass, accumulating and mixing in the centre of the Northern Ionian. The LIW spreading path is identified both from the high salinity and low potential vorticity values on the 28.8 isopycnal surface. Some LIW then spreads west and south towards Sicily,...

Etude de la lumière visible comme facteur limitant de la survie de Escherichia Coli en milieu Marin
Provedor de dados: 5
Autores: Gourmelon, Michele.
L'étude de Escherichia coli en microcosmes d'eau de mer à 34 /1000 de salinité, exposé à la lumière visible montre que cette bactérie évolue rapidement (en quelques heures) vers un état viable non cultivable tandis qu'à l'obscurité, la capacité à cultiver se maintient plus longtemps. Deux facteurs principaux semblent déterminer la survie de Escherichia coli dans l'eau de mer lors de l'exposition à la lumière visible : l'état de la bactérie au moment du rejet et la qualité du milieu récepteur. L'état de la bactérie avant exposition à la lumière visible joue un rôle important dans sa survie : en effet, quand il est en début de phase stationnaire avant son séjour dans l'eau de mer, Escherichia coli résiste mieux au stress lumineux que lorsqu'il est en phase...

Historique de la raréfaction des poissons marins (incidence des activités de pêche sur les poissons dans les eaux marines d'Arcachon du 18eme siècle a nos jours)
Provedor de dados: 5
Autores: Quero, Jean-claude; Cendrero, Orestes.
Au 18ème siècle, dans la moitié sud du golfe de Gascogne, caractérisée par un plateau continental plus étroit, le bassin d'Arcachon, vaste lagune ouverte sur la mer, était considéré par Le Masson du Parc (1727) comme "un des plus poissonneux que l'on puisse voir". L'auteur écrivait que de "mémoire d'homme" le niveau des captures n'avait pas sensiblement diminué. Environ 500 marins péchaient presque exclusivement dans le Bassin à la saison chaude. La moitié d'entre eux sortaient en mer capturer du poisson à la saison froide, les autres récoltant les coquillages dans la lagune. Des données postnapoléoniennes montrent d'après l'importance de sa population maritime, que le Bassin était la pêcherie la plus importante de la côte Atlantique française tout au...

L'exploitation rationnelle des ressources de la mer. Gestion des bassins conchylicoles
Provedor de dados: 5
Autores: Kopp, Joel; Joly, Jean-pierre; Le Gagneur, Eric; Ruelle, Francois.
L'élément marquant intervenu durant l'année 1995 est l'augmentation considérable de la production d'huîtres commercialisables sur l'ensemble du littoral avec 44.000 tonnes produites en 1995 (dont 34.500 t pour le seul département de la Manche) contre 36.000 tonnes en 1990. Cette augmentation était déjà pressentie dans un précédent rapport (Jeanneret et al, 1992), car de nombreux terrains concédés n'étaient pas encore mis en exploitation. Le mot "commercialisable" est important car il ne préjuge pas de la quantité d'huîtres réellement commercialisée. On sait combien la campagne de vente 1995 a été difficile pour l'ensemble des ostréiculteurs français, avec notamment un effondrement des prix de vente à la production (- 30 %) et une part importante d'invendus...

Hydrogen-peroxide determination in estuarine and marine waters by flow-injection with fluorescence detection
Provedor de dados: 5
Autores: Amouroux, D; Donard, Ofx.
The Scopoletin-Peroxidase fluorescence decay method has been developed using standard additions and a flow injection manifold for hydrogen peroxide (H2O2) determination in marine waters. The limit of detection of the method was optimized using stored milli-Q water with a minimum of 5 nM (3 sigma). The method was found to be linear from 5 to 700 nM, with an approximate relative standard deviation of 10%. This accuracy was verified on both milli-Q and natural waters running systematically duplicate analysis. The validity and the sensitivity of the technique was studied through the influence of pH, salinity and the dissolved organic matter (DOM) concentration. Standard additions avoided all matrix and experimental interferences, making it possible to use this...

Nutrients levels of marine water along the North of France coastline are growing-up. They have a good chance to become a problem in the future. Since 1992, a network of three radial lines is sampled at regular interval to supervise on long term : 1. Parameters levels that show the environment quality (temperature, salinity, turbidity,total suspended matters, organic suspended matters, chlorophyll, phaeopigments, phytoplankton). 2. Nutrients concentrations ( ammonia, nitrite, nitrate, phosphate, silicate) that enrich the environment , and may be responsable of its deterioration. The report shows the results of the first three years survey. I t strikes a correlation between the tested parameters and takes stock of the present situation.

In February 1994, during the SAMBA 1 cruise, 9 CTD casts were done and 22 subsurface floats (20 MARVOR, 1 VCM, 1 ALFOS) launched near 800 dbar in the Brazil basin, within the framework of the SAMBA Experiment. SAMBA (SubAntartic Motions in the Brazil bAsin), is a component of the WOCE float program, and aims at describing the absolute general circulation of the Antarctic Intermediate Water around 800 m depth in the Brazil basin. MARVOR and ALFOS floats cycle every 2 months between thier nominal depth and surface to transmit data via the ARGOS system and were programmed for 30 cycles, i.e. a total life of 5 years. THE VCM float, on the other hand is a one shot RAFOS-type float which was programmed for a 1.5 year mission at depth. This report presents the...

The present study was conducted to determine the presence and physiology of mesophilic sulfate-reducing bacteria (SRB) at deep-sea hydrothermal vents, which constitute remote ecosystems, largely dependent on their own chemoautotrophic primary production. SRB were enriched and isolated from samples of hydrothermal water, invertebrates, chimneys, and sediment collected at deep-sea (1700 to 2600 m) hydrothermal vent sites in the Lau Basin, in the North Fiji Basin, and at 13 degrees N on the East Pacific Rise. From the hydrothermal fields in the Lau Basin and the North Fiji Basin, SRB were cultured at 30 degrees C from 19 out of 21 samples, including five samples of high-temperature hydrothermal water (&gt; 100 degrees C).

Autores: Mouhri, K; Marsot, P; Pelletier, E; Loudiki, M; Saintlouis, R.
Tributyltin (TBT) is a toxic organometallic compound, used as a biocide in marine antifouling paints, that may be harmful to marine organisms living in coastal waters. This study attempts to provide a better understanding of the effects of TBT on the growth and metabolism of a dominant marine diatom from the St Lawrence Estuary: Phaeodactylum tricornutum. Experiments were conducted in batch cultures exposed during one week to TBT concentrations ranging from 0.5 to 20.0 mu g l(-1). The algal growth was much reduced by concentrations of 2.0 to 20.0 mu g l(-1), with reduction of cell density and cell death occurring within a few days at higher TBT concentrations. Exposure to pollutant also resulted in mucilaginous agglutination of cells into large, rapidly...

Absorption et régénération de l'azote dans les écosystèmes côtiers ; relations avec le régime de mélange vertical des masses d'eaux ; cas du domaine homogène peu profond de la Manche Occidentale.
Provedor de dados: 5
Autores: Maguer, Jean-francois.
La production primaire dans l'océan est généralement limitée par l'azote. Ceci a été mis en évidence dans le domaine océanique (Thomas, 1966 ; 1969 ; Eppley et al., 1973) et dans les eaux côtières (Ryther et Dunstan, 1971 ; McCarthy et al., 1977). Par ailleurs, dans l'eau de mer, les cycles biogéochimiques des principaux éléments (C, N, P) sont étroitement liés (Redfield et al., 1963) et l'azote, en contrôlant la production primaire, règle pour une large part les flux des différents composés. Il régule en particulier les flux de carbone dans la zone euphotique et vers les couches profondes, déterminant ainsi la capacité des écosystèmes à exporter la matière organique.

Ecophysiologie du ver tubicole Lanice conchilega : compétition trophique avec l'huître japonaise Crassostrea gigas en Baie de Veys (Baie de Seine Occidentale)
Provedor de dados: 5
Autores: Ropert, Michel.
The trophic competItIon between the Pacific oyster Crassostrea gigas and the polychaete Lanice conchilega was studied by assessing the polychaete suspension feeding activity. Particle size distributions were compared at the input and output of the experimental design so as to estimate the polychaete retention efficiency. Although particles ranging from 4 µm to 12 µm were kept by Lanice conchilega, no upper treshold and maximum retenti on rate were reached. In contrast, Crassostrea gigas showed a retention efficiency starting at 2 µm and reached a 6 to 8 Ilm upper treshold. Based on our results, a trophic competition is likely to occur between Crassostrea gigas and Lanice conchilega. Standardized filtration rates reached 0.27 l.h-1.dmw-1 and 2.41...

Etudes sur les mortalites larvaires de la coquille st Jacques Pecten maximus en ecloserie
Provedor de dados: 5
Autores: Robert, Rene; Miner, Philippe; Nicolas, Jean-louis; Mazuret, Michel; Connan, Jean-paul.
Larval mortalities occurring in molluscan hatcheries have often been associated with bacterial contamination. Although batches of oyster and clam larvae have been routinely reared in the hatchery of Argenton without antibiotics, high larval mortalities have been recorded with Pecten maxirnus under similar conditions. For this species, an addition of chloramphenicol was found necessary. However, this chemical has now been banned in Europe. Thus either substitition products or an improvement in the rearing procedures is essential. Studies carried out have shown that neither a decrease in larval density (1 larvae. ml"l) nor sea water change frequency (1 per day) had any positive effects. Furthermore, elective substances such as sugars were not suitable and...

This document presents a year-long (1994) environmental study conducted on a site of intensive farming of salmonids (mainly fario trout) in Camaret Bay. A set of parameters were considered for the body of water and the sea bed (flow patterns, hydrology, sedimentology, biology, chemistry) and complemented by video observations. The study concluded that there was a measurable effect from the farm in its current configuration, but that the impact was of a very limited intensity and scope that did not affect the environment in a substantial way. It is recommended that production growth be accompanied by a minimum amount of environmental assessment.

In spite of its young age, aquaculture is now an activity subject to competition just like any other activity in the agri-food sector. The differences in environmental conditions give comparative advantages to operations located in certain sites, but the intensification of production methods tends to reduce the impact of this natural variation. It is for this reason that aquaculture must seek sources of competitiveness in the quality of its products, which is not limited to just freshness or taste and includes meeting the increasing demand for diversity. A quality process requires knowing how to assess modifications in product characteristics with respect to environmental conditions and culture techniques and should allow producers and consumers to clearly...

Scattering of inertial waves by an ocean front - Comments
Provedor de dados: 5
Autores: Klein, Patrice; Treguier, Anne-marie.
Rubenstein and Roberts (1986, hereafter RR86) have studied the scattering of inertial waves by a geostrophic jet. The most remarkable effect of the jet is to concentrate near-inertial energy in the negative vorticity region. This effect is due to the horizontal dispersion of near-inértial waves. It is demonstrated by RR86 Using a stratified linearized model. A similar result has been obtaîned by Kunze (1985) using a ray-tracing approach and bas been confirmed by observations (Kunze and Stanford 1984). Another result of RR86 concems the mixed layer depth variations. Their Figs. 3 and 8 show a systematic downwelling in the negative vorticity region of the jet and systematic upwelling in the positive vorticity region. Although large upwellings and...

Autores: Shapiro, Gi; Meschanov, Sl; Emelianov, Mv.
In January 1990 a Meddy was observed 100 km to the west of the Irving Seamount just after it had passed through a narrow passage (90 km at its narrowest) between Hyeres and Irving Seamounts located at the western edge of the Canary Basin. Vertically, Meddy ''Irving'' had two cores centred at 900 and 1150 m depth. In the horizontal plane the Meddy had an elliptical shape with axes of 100 and 60 km. Behind the Meddy, a wake of saline water was found which tracked the lens trajectory. Two small salty patches were observed inside the wake. They had the same temperature-salinity relationships as the lens periphery and were probably split from Meddy ''Irving'' during the impact with bottom topography. The patches contained approximately 20% of the whole lens...

This model is based on the assumption that photosynthesis of microphytobenthos is primarily determined by irradiance at the sediment-water interface and by the photophysiological response of microalgae to changes of this irradiance. So, irradiance recordings at the sediment-water interface were used as the forcing variable. The simulation indicates that before the introduction of the brown tide, primary production of microphytobenthos was physically controlled. Light levels, hence primary production rates, were very variable (&lt;1-132 mg C m(-2) d(-1), CV = 80%) because wind-induced resuspension generates turbidity...

An evaluation of the policy of fishery resources management by TACs in European Community waters from 1983 to 1992
Provedor de dados: 5
Autores: Biais, Gerard.
In 1983, the European Community (EC) agreed on a system for the conservation and management of fishery resources whi h is based largely on the use of annual total allowable catch (TAC). Nevertheless, the state of many European stocks of demersal species has worsened since 1983. A review of TAC enforcement shows that landings have exceeded TACs to a limited estent for these resources. The contrary is observed for the stocks of pelagic species of which the state has improved although landings have frequently been larger than TACs. This double paradox generates a feeling of limited impact of the TAC system inmplemented by the EC. To investigate the reasons, the closeness between agreed TACs and scientific recommendations has been examined. The results show...

Autores: Lafuente, Jg; Jurado, Jll; Lucaya, Nc; Yanez, Mv; Garcia, Ja.
An analysis of current velocity, temperature and salinity data collected between 15 November 1990 and 24 July 1991 in the Ibiza Channel has been made to illustrate the circulation of the different water masses within this area. At certain stages of early winter, outstanding intrusions of Modified Atlantic Water, lasting a few days, have been observed flowing northwards along the eastern part of the Channel. Western Mediterranean Intermediate Water appeared for the first time during the middle of February; from March onwards, the thickness of the layer of this water mass increased until it reached its greatest presence during early summer. Simultaneously, the amount of Levantine intermediate Water decreased at the mooring site, being replaced by the MAW....

Observations et réflexions sur la contamination bactériologique des mollusques gastéropodes
Provedor de dados: 5
Autores: Le Mao, Patrick; Gerla, Daniel; Rougerie, Michel.
Un suivi en parallèle des contaminations bactériologiques de moules et de patelles en milieu naturel a montré que ces dernières se contaminaient fortement en zone polluée. L'analyse des données obtenues par les D.S.V. sur d'autres espèces de gastéropodes lors de leur commercialisation permet de constater que d'autres espèces (bigorneaux Littorina littorea et bulot Buccinum undatum) sont également susceptibles de retenir des germes fécaux bien au-delà des Dormes de commercialisation définies par la directive CEE 91-492 du 15/07/91. Ceci pose le problème du classement des zones de pêche des gastéropodes et de leur éventuelle purification avant commercialisation.

Cette mission fait suite à celle déjà effectuée en Avril 1994. Les premiers traitements des données hydrologiques de l'atoll de TAKAPOTO laissaient apparaître une variabilité faible du milieu tant au niveau spatial que temporel. Les résultats montraient cependant une variabilité intra-journalière non négligeable. Afin de mieux quantifier ces variations et d'offrir un support pour la modélisation, il apparut nécessaire d'utiliser une sonde multi-paramètres EMP 2000 de chez Applied Microsystems acquise en 1994 par l'Unité de Recherches Ecosystèmes Conchylicoles de la Station de La Tremblade. Cette sonde permet l'enregistrement simultané et en continu de différents paramètres tels que la hauteur d'eau, la température, la salinité, la turbidité, la lumière, la...

Phosphatogenèse en atolls polynésiens : la filiation mattes cyanobactériennes - phosphorites
Provedor de dados: 5
Autores: Jehl, C; Rougerie, F.
Brackish ponds and lagoons located on Polynesian atolls are frequently colonized by thick cyanobacterial mats. The accumulated organic material (OM) is preserved due to prevailing anoxia. The high productivity of these microbial mats is controlled by high nutrient contents in the interstitial waters of the underlying limestone, in accordance with the geothermal endo-upwelling process (Rougerie and Wauthy, 1986, 1993). Observations and micro-analysis carried out on insular phosphate samples, and a comparative study of hydrocarbons extracted from kopara and phosphate, indicate a genetic link between the diagenetic evolution of the trapped OM and the apatite precipitation as follows: growth of thick microbial mats in brackish ponds and closed lagoons, and...

As part of the contract between IFREMER and CITPPM (Confédération des Industries de Traitements des Produits de la Pêche Maritime), a study was undertaken to know the influence of sorne manufacture parameters on quality of canned anchovy.  Various factors have been studied : quality of raw material, salting time in tank, ripening temperature, pressing or drying rate and also storage temperature after manufacture.  This report presents only sensory results; the others analytical data are discussed in a synthetic report on this study.  Sensory evaluations show a real effect of raw material quality on final product and it seems that fish glazing and a too long time of salting prevent development of ripening caracteristics.  With regard to others factors; it...

Autores: Fernandez, E; Maranon, E; Cabal, J; Alvarez, F; Anadon, R.
Export of particulate matter out of the euphotic zone was measured in the southern Bay of Biscay in summer 1993 using shallow (50 m) sediment traps deployed for a short period in outer shelf waters. The sedimented material consisted of intact and degraded faecal pellets, diatom frustules, coccolithophorid cells, detached coccoliths and zooplankton remains. Measured vertical fluxes were 173-236 mg C m(-2) day(-1), 18-20 mg N m(-2) day(-1) and 3.8-4.5 mg C m(-2) day(-1), respectively for particulate organic carbon (POC), particulate organic nitrogen (PON) and particulate inorganic carbon (PIC). The downward flux of POC represented 24-37% of the estimated primary production. Export of PIC accounted for only 2% of the total carbon flux. A large proportion...

This report describes the mussel Mytilus edulis sampling stock strategy developed to carry out stock assesments along the French Normandy coastline between 1989 and 1993. The overall totalnetweight reached 13,992 metric tons in 1993 with 27% precision level. Simultaneously, a growth study was carried out on 36 experimental sites to estimate overall variability. Individual total weight varied from 6.6 to 12 g at rearing cycle completion. An empirical management model conceming the Western Cotentin rearing areas was proposed and explained 68% of total weight variance. Based on a stepwise multilinear relationship, the model linked overall growth performance to local stocking density, tidal distribution, and distance from the main runoffs inputs. It aims to...

Deep structure of the northern Kerguelen Plateau and hotspot-related activity
Provedor de dados: 5
Autores: Charvis, P; Recq, M; Operto, S; Brefort, D.
Seismic refraction profiles were carried out in 1983 and 1987 throughout the Kerguelen Isles (southern Indian Ocean, Terres Australes and Antarctiques Francaises, TAAF) and thereafter at sea on the Kerguelen-Heard Plateau during the MD66/KeOBS cruise in 1991. These profiles substantiate the existence of oceanic-type crust beneath the Kerguelen-Heard Plateau stretching from 46 degrees S to 55 degrees S, including the archipelago. Seismic velocities within both structures are in the range of those encountered in 'standard' oceanic crust. However, the Kerguelen Isles and the Kerguelen-Heard Plateau differ strikingly in their velocity-depth structure. Unlike the Kerguelen Isles, the thickening of the crust below the Kerguelen-Heard Plateau is caused by a 17 km...

Intermediate water formation in the Ligurian sea
Provedor de dados: 5
Autores: Sparnocchia, S; Picco, P; Manzella, Gmr; Ribotti, A; Copello, S; Brasey, P.
Observations carried out in the Ligurian Sea in February 1969 during the MedOc experiment permitted the identification of a dense water formation episode. A new experiment was conducted in the same area during 1991 in the framework of the PRIMO programme. Water temperature, salinity and vertical velocities were measured using a CTD probe and ADCPs. The data have shown the formation of dense water with temperature and salinity properties significantly different from those found during the MedOc experiment. In 1969, strong cold winds caused the mixing and cooling of the water column to a depth of 1200 m. In 1991, the surface forcings were not strong enough to erode the stratification from the surface to the bottom, and the dense water formed found its...

Analyse et prédiction de la dispersion des radioéléments dans l'environnement marin par la méthode de la réponse impulsionnelle
Provedor de dados: 5
Autores: Boust, D; Hairie, A; Fraizier, A; Baron, Y.
This work presents analysis and prediction of the dispersion of radioelements in the marine environment based on the pulse response theory. The analysis is made on three data sets over the period 1984-1988 : the amounts of gamma-emitting radioelements contained in controlled releases from the nuclear reprocessing plant of La Hague (=signal emission point), and gamma-emitting radionuclide concentrations in sea water at two stations (=signal reception points), situated at 8 and 35 km distance from the release point. Using this data base, the pulse response is determined for each station and for each element. This allows us to estimate the mean delay and the amplitude of the reception signal (i.e. the concentrations of radioelements) and its sensitivity to...

Since early 1993 the Aquaculture Resources department MOIlusc NEtwork (REMORA in French) has been monitoring homogeneous batches of Crassostrea gigas (initially 18 months old, same origin, same history, same size) in the main French production areas. The monitored parameters deal with growth, morphology, survival, composition and parasite infestations. The comparison between two rearing conditions (in traditional bags and on wooden plate to which individuals are stuck) shows a tendency for the oysters to become wider on plates (which is probably linked to the fact that there is no shell erosion) and to grow more (which could also been explained by the lower local density). Major regional characteristics are shown by the analysis, especially in terms of...

Le devenir des bactéries entériques rejetées en mer a été étudié sur cinq zones côtières du littoral français : la côte Ouest du Cotentin, la rade de Brest, l'estuaire de Morlaix, la rade de Toulon et la Baie de Fort de France. Sur chaque site, une étude a permis de déterminer les concentrations en coli formes thermotolérants et en streptocoques fécaux dans les principaux apports. Les salmonelles ont également été recherchées sur trois de ces secteurs. Un calcul de flux permet d'apprécier l'importance des rejets urbains. Dans ces eaux généralement très chargées en contamination fécale, la présence de salmonelles a presque toujours été détectée.

The Atlantis II Deep is located at about 21.5 degrees N within a deep trench which divides the Red Sea along the mid-axis. Data from the Atlantis II mooring, maintained during January-February 1978, provide valuable information about residual current distribution over the whole water column. The residual currents have speeds of 20 cm/s at the level of surface current meter, decreasing to 1.5 cm/s at about 250 m depth. The dominant direction over this depth level is southeast in January and changes to northeast in February. From 250 m down to the bottom the dominant direction is north-northwest and the residual speeds range between 1.5 and 3.0 cm/s at different depth levels.

In order to estimate the losses of CaCO3 from bioerosion (grazing and boring), experimental coral substrates were laid in the lagoons of high islands and atolls in French Polynesia. After six months of exposure, the sites could be divided into those exhibiting net bioerosion and those exhibiting net accretion. Of the five sites exhibiting net bioerosion (grazing and macroboring greater than accretion), three were located off high islands and two in atoll lagoons. The average net rate of bioerosion was greatest at Faaa in Papeete Bay, Tahiti (10.45 kg.m(-2).yr(-1)). Of, the two sites exhibiting net accretion, the greatest rate of gain (0.81 kg.m(-2).yr(-1)) was recorded at the eastern site in Takapoto lagoon. Recorded differences in the composition and...

Autores: Lavenant, M; Paquotte, Philippe.
Two major constraints to aquaculture have raised in most countries : the little availability of convenient sites because of the competition for the use of the coastline and the progressive implementation of regulations to reduce the impact of the farms on the environment. The technique of recirculation, widely used for hatcheries, has been developed to answer these constraints and to get free of the natural variations in order to regulate the résults. The ongrowing experimental facilities have proved good enough results to make it possible to conceive industrial projects for sea-bass and turbot. In first approach, the production costs of these systems are similar to traditional techniques but expected productivity gains due to an increase of zootechnical...

Autores: Renault, Tristan; Cochennec, Nathalie.
Grossly visible lesions of the ctenidia and occasional mortalities in Japanese oyster Crassostrea gigas from the Atlantic French coast were reported in 1992-1993. From August 1992 to March 1993, 235 living oysters were collected to determine the cause of tissue lesions and mortalities. Microscopical examination of fixed, stained sections revealed that 53 2% of these oysters had ctenidia and mantle lesions associated with irregular basophllic and Feulgen positive cytoplasmic inclusion bodies. Ultrastructurally, the infectious agent was a chlamydia-like organism. Indirect fluorescent and peroxidase conjugated antibody tests suggested that this agent might share common antigens with the prokaryotic agent Chlamydia psittaci, strain ovis

The effects of Hg concentrations ranging from 0 (control) to 1024 mu g l(-1) upon embryogenesis, survival and growth of Mytilus galloprovincialis mussel larvae were investigated. Embryogenesis was abnormal in 50% of the individuals at 10 mu g l(-1). The 48 h LC(50) for D-shaped, early umbonate, late umbonate and eyed larvae were 51, 164, 322 and 383 pg l(-1) respectively. The LC(50) was an allometric function of ash-free dry weight with exponent b = 0.60. Larval growth was significantly reduced after 6 d exposure to 4 mu g Hg l(-1) and after 10 d exposure to 2 mu g l(-1). No significant differences in lethal or sublethal sensitivity to Hg were found between M. galloprovincialis and previously studied Crassostrea gigas embryos and larvae. The implications...

In this study we analyze two groups of Mediterranean salt lenses: ''mid-life'' lenses, typically 1-2 years old, observed in the Canary Basin, and younger Meddies from the Iberian Basin. In contrast to turbulent features, vortex lenses have a clear coherent structure in the temperature and salinity fields. This physical property supports the hypothesis that a mathematical description with only a few degrees of freedom may exist. We use nonlinear transformation of variables to find a unique function describing vertical profiles at different locations inside the lens. When this function is found, its existence is considered as ''self-similarity'' of the lens structure. We also found a common function that describes each group of Meddy, Canary and Iberian, and...

Firstly, the consumption and distribution aspects are approached, followed by a description of fish as primary material for industry, emphasising the constraints related to fishing and aquaculture. Then, the main sectors of transformation are presented as far as the use of by-products and co-products. Finally, information is provided on the transposition of industrial systems into small-scale models, followed by a briet glimpse of the localisation of the French fishing industry.

Climatic fluctuations, current variability and marine species distribution - a case-study in the Ligurian sea (north-west Mediterranean)
Provedor de dados: 5
Autores: Astraldi, M; Bianchi, Cn; Gasparini, Gp; Morri, C.
The Ligurian Sea, situated in the north-east corner of the western Mediterranean, is colder than the Tyrrhenian Sea, situated just to the south. As a consequence, there are differences in the composition and physionomy of their respective marine biota. Episodical records of epibenthic warm-water species, of Tyrrhenian origin, in the colder Ligurian Sea were paradoxically linked to the occurrence of low mean air temperatures. This is explained by the peculiar pattern of water and heat exchanges between the Tyrrhenian and Ligurian basins mediated through the northward-flowing Tyrrhenian Current. In response to the greater cooling of the Ligurian Sea, induced by the more intense water and temperature losses, a seasonal flux of warmer water is drawn from the...

Problemes de calcification chez Pecten maximus en rade de Brest
Provedor de dados: 5
Autores: Larvor, Helene; Devauchelle, Nicole; Cuif, Jean Pierre.
Calcification abnormalities linked to the appearance of a brown coloration of the internal shell layer are observed in scallops Pecten maximus in the Brest roadsted. It is a widespread phenomenon in shallow waters (about 3 to 10 meters) sometimes associated with an important boring parasitism at the ultimate stage of development. This brown color which can generate a decrease of the consumer appraisal does not affect the commercial value of the shellfish (muscle and gonad quality) when it is not too high. When it covers the all shell with a deap brown color the animal shows many signs of weakening. The color of the internal layer of the valves is due to the presence of a brown pigment, an eumelanin, associated with the insoluble organic matrix of the...

Bonamia ostreae, parasite of the European flat oyster, Ostrea edulis, does not experimentally infect the Japanese oyster, Crassostrea gigas
Provedor de dados: 5
Autores: Renault, Tristan; Cochennec, Nathalie; Grizel, Henri.
The protozoan Bonamia ostreae (Ascetospora) is the etiological agent of bonamiosis, or hemocyte disease of the European fiat oyster, Ostrea edulis (Pichot et al., 1980). Since this infection was first reported from the coast of Brittany (Comps et al., 1980), the parasite has spread rapidly along the French Atlantic coasts (Grizel &amp; Tigé, 1982), and in the European countries including the UK, Holland, lreland and Spain (Bannister &amp; Key, 1982; Van Banning, 1982; Polanco et al., 1984). Under the EEC Council Directive 91/67, this parasitic protozoan is included in list II of Annex A. Serious pathogen agents for molluscs that should be obligatorily declared are placed in this list

Note sur la pêche du lompe (Cyclopterus lumpus) à Saint-Pierre et Miquelon en 1994
Provedor de dados: 5
Autores: Briand, Daniel.
En Amérique du Nord, le lompe (Cyclopterus lumpus) est signalé depuis la Baie d'Hudson et la côte du Labrador jusqu'au New Jersey. En mer, on en trouve d'importantes concentrations sur le Banc Saint-Pierre, au large de la côte sud de Terre-Neuve.  Le lompe, au moment du frai, se rapproche du rivage et recherche des fonds rocailleux, où les algues poussent en abondance. Il semble que l'espèce ait tendance à revenir aux mêmes endroits pour frayer.  Le frai a lieu immédiatement après la migration des adultes (âgés d'environ 5 ans et plus) vers la côte en mai et juin.  Après avoir déposé des oeufs qui ressemblent à de grosses masses spongieuses, les femelles retournent en mer, laissant aux mâles (qui présentent alors une couleur rougeâtre) le soin de garder...

Cobalt in the western Philippine Sea
Provedor de dados: 5
Autores: Wong, Gtf; Pai, Sc; Chung, Sw.
The distribution of cobalt was determined at one station in the oligotrophic western Philippine Sea that is far removed from the direct influence of any major land mass. Concentrations of cobalt (&gt; 95 pM) in the top 150 m of water in and above the thermocline were much higher than those (about 25 pM) in the deep waters below 1000 m. Since no major river drained directly into the study area, these elevated concentrations in the surface waters could not have been sustained by a riverine input. A more likely source of cobalt to these waters might have been atmospheric deposition. Below 150 m, as a first approximation, the relationship between cobalt and salinity mimicked that between potential temperature and salinity with inflection points occurring at...

The interaction between the catalan and balearic currents in the southern catalan sea
Provedor de dados: 5
Autores: Salat, J.
The Liguro-Provencal-Catalan current, associated with a permanent shelf/slope front, terminates near the Eivissa channel, in the southern part of the Catalan Sea. Also in this region, the North Balearic front is formed, associated with lighter waters of recent Atlantic origin. In May-June 1991, the oceanographic cruise FE'91 was carried out covering the region with CTD casts. The results of water mass analysis and geostrophic circulation are presented in this paper, and the interaction between the Catalan and North Balearic currents is described and discussed.

Autores: Blanchard, Michel; Thomas, Gerard.
Une opération expérimentale de nettoyage des crépidules a été entreprise à Fouras entre le 9 et le 12 mai 1995. Les quantités de crépidules enlevées à proximité des concessions ostréicoles ont été estimées à 150 tonnes. Après cuisson, à l'aide d'un système de type hollandais, elles ont été déposées dans une fosse marine au large de l'île d'Aix. Il convenait de s'assurer de l'efficacité du traitement et de l'innocuité des rejets pour le milieu marin. Les mesures et observations, effectuées par l'IFREMER avant, pendant et postérieurement à cette expérimentation, font l'objet du présent rapport. Au vu des résultats, le traitement semble efficace et la perturbation mineure sur le milieu.

Précontrat de baie "golfe du Morbihan" Mesures de flux nutritifs et inventaire d'algues vertes en 1995
Provedor de dados: 5
Autores: Piriou, Jean-yves; Chapron, Victorien; Annezo, Jean-pierre.
The gulf of Morbihan, without manifesting any pronounced signs of eutrophication, has, in 1995, three sites of green algae proliferation: the Auray river estuary, the branches of the Vannes and Séné estuary, as well as the outlet of the Noyalo's estuary. They are also the three sectors of the gulf that receive the most nutrient salts, in particular, nitrogen, which is a determining factor in the development of nitrophilic green algae (Ménesguen and Piriou 1995). During spring the nitrogen seems to come as much from urban sources (Vannes, Auray) as from agricultural sources coming from the northern catchment areas of the gulf.

70 hydrothermal sites were observed during the 23 dives of the French submersible Nautile (''Naudur'' cruise, December 1993), at 17-degrees-19-degrees-S on the East Pacific Rise. Large vent-animal communities are present around these sites. The zoological composition of these communities is the same as that of the communities at 11-degrees-13-degrees-N and 21-degrees-N on the East Pacific Rise. However, the distribution of the species on the sites is different from all the other hydrothermal communities; large anemone fields of several hundred square metres, associated with colonies of Bathymodiolus and Calyptogena, have been observed. Fresh lava areas seem to bear the most important biological activity.

Autores: Laroche, Jean; Benoely,; Siaviri, A.
Traditional fishing using beach seines was studied over a period of one year at the mouth of the Onilahy river. The catches/efforts were recorded on a daily basis, biological sampling and the measurement of hydrological parameters being carried out twice a month. The moderate variations of salinity and temperature (14 &lt; salinity &lt; 35; 25 degrees C &lt; temperature &lt; 30 degrees C) which were observed in the estuary can be explained by the semiarid climate of the area. Four species of penaeid shrimps are to be found on the Onilahy: Metapenaeus monoceros, Panaeus indicus, Penaeus monodon and Penaeus japonicus, which were mainly caught at the subadult/adult stage with a Carapace length between 10 and 50 mm.

Tidal currents in the western mediterranean-sea
Provedor de dados: 5
Autores: Alberola, C; Rousseau, S; Millot, C; Astraldi, M; Font, J; Garcialafuente, J; Gasparini, Gp; Send, U; Vangriesheim, Annick.
A large number of several-month current time series is now available in the western Mediterranean Sea, and harmonic and spectral analyses provide spatially coherent information about the major tidal (M2, S2, N2 and K1) currents in the region. When they are significant, these currents are generally barotropic, they mainly rotate clockwise and their ellipses have orientations that are strongly dependent on the local bathymetry. From the Alboran Sea to the Algerian Basin, the Ibiza Channel and as far as the Sardinian Channel, the velocities of the semidiurnal components continuously decrease from a few 10(-2) m/s in the west to 10(-3) m/s and even less in the east. The phases increase eastward from the Alboran Sea to 3-4 degrees E in the western Algerian...

INTRODUCTION Problématique générale Les zones marines côtières reçoivent des rejets d'eaux urbaines et agricoles qui contiennent de grandes quantités de micro-organismes dont certains sont pathogènes pour l'homme (par ex. virus de l'hépatite A. ..). Dans les environnements hostiles, la dispersion et conditions de survie défavorables (énergies lumineuse importante, eau oligotrophe...)  font que les bactéries disparaissent rapidement ou évoluent vers un état non cultivable. Par contre, certains milieux comme les sédiments, les eaux turbides ou eutrophisées, présentent des conditions favorables à la survie des bactéries d'origine entérique et à la protection physique des particules virales.

Maritime salt-marshes of the Eyre's delta located in Arcachon Bay (South-West Atlantic coast of France) were studied following to a recent work of Soriano-Sierra (1992). In the se tidal areas salt marshes develop at the top of mud-flats covered by Zostera noltii beds, and in the vicinity of fish ponds who are lagoonal impoundments of the 18th century. Along the Eyre's estuary where salinity is reduced by seepage of fresh water from the land, Spartina maritima and other halophilic plants tend to be replaced by a taU marsh of Phragmites communis, Scirpus maritimus and Juncus gerardii.

This work is part of the program, "recruitment determinism in scallops" initiated in 1992 by the "Contrat de Baie". The aim of this research was to explain interannual abundance fluctuations observed for Pecten maximus, in the Bay of Brest. To this end an analytical approach to the life cycle of the species was undertaken to determine its critical phases. A phase may be considered as "critical" if the mortality rate at its level varies from one year to the other. Using data from 1989 to 1994, a precise time-table of the "physiological year" of the scallop in the Bay of Brest was determined. Fecundity and gamete production kinetics were estimated from the annual variation in the weight indices of the gonad. In the laboratory, egg quality was estimated...

A dynamic model for generating small-scale heterogeneities in ocean floor basalts
Provedor de dados: 5
Autores: Bideau, Daniel; Hekinian, Roger.
Small-scale distribution of basaltic compositions along the mid-ocean ridge crests suggests that the magmatic processes are sensitive to spatial and temporal fluctuations related to proximity of ridge hot spots, changes in spreading rate, thermal boundary effects associated with ridge offsets, off-axis volcanoes and ridge propagators, and variations in magma supply through time. A detailed sampling of the East Pacific Rise (EPR) axis, near 13 degrees N, revealed that complex basalt compositional variations unrelated to morphology and structure occur both on the ridge axis and on nearby off-axis seamounts. This small-scale heterogeneity is attributed to successive magmatic cycles separated by periods of quiescence (amagmatic phases) where each cycle...

Contribution à l'étude de virus de mollusques marins apparentés aux Iridoviridae et aux Herpesviridae
Provedor de dados: 5
Autores: Le Deuff, Rose-marie.
Among the marine molluscs, Pacific oyster, Crassostrea gigas, is actually the most reared species in the world. Noticeably in France, where it was imported between 1960 and 1970, and replaced Portuguese oyster, Crassostrea angulata. Intensification of breeding and the associated introductions of new species may be hazardous. Indeed, they might be responsible for the appearance and the dissemination of new diseases in bivalve molluscs. In addition to these observations, the quasi monobreeding of C. gigas in France enhances the necessity to develop research concerning the diagnosis of pathologies affecting this species, namely the diagnosis of viral diseases. Several families of viruses have been described within marine bivalves molluscs. The purpose of this...

La Bonamiose : mise au point de réactifs pour le diagnostic et étude des mécanismes cellulaies de défense développés par l'hôte, l'huître plate, Ostrea edulis
Provedor de dados: 5
Autores: Cochennec, Nathalie.
Une partie de ce travail, a consisté à développer quelques techniques pour la caractérisation et le diagnostic de ce protozoaire. Ainsi, après avoir optimisé le protocole de purification de B. ostreae, il a été possible de définir quelques unes des propriétés des protéines de ce parasite dont la connaissance s'avère nécessaire pour le choix de cibles potentielles d'un diagnostic. Cette caractérisation des protéines a été réalisée par la description des profils électrophorétiques en SDS-PAGE, et par la recherche des glycoprotéines à l'aide d'une lectine. Nous nous sommes également attachés à la préparation d'anticorps polyclonaux spécifiques du parasite, dans l'optique de disposer d'une technique de diagnostic sensible, fiable et rapide. En outre, ce type...

Contrôle du phytoplancton du bassin Ligure par le front liguro-provençal (secteur Corse)
Provedor de dados: 5
Autores: Goffart, A; Hecq, Jh; Prieur, L.
The evolution of the phytoplankton distribution was monitored along the Calvi-Nice axis, from Calvi to 30 miles offshore, in relation with the hydrological features of the Liguro-Provencal front (Corsican sector) and nutrient availability. Oceanographic cruises repeated between 1982 and 1991 have emphasized the permanence of the front and the perennial stability of its hydrological characteristics. Moreover, the front and the associated vertical circulation influenced strongly, and in a reproducible fashion, the algal distribution within distances of few kilometres. In March, stabilization of the upper layers of the water column, induced by a beginning of vertical stratification, is the main factor controlling the onset of the phytoplancton bloom in the...

Autores: Sanchezcabeza, Ja; Molero, J; Merino, J; Pujol, L; Mitchell, Pi.
A number of nuclear power installations located in the north-western Mediterranean (NWM) area are known to enhance Cs-137 levels in various marine compartments. The nuclear fuel reprocessing plant at Marcoule (France) has been reported to originate a significant increase of Cs-137 in Rhone river waters and sediments because of the discharge of low-level liquid radioactive waste. This radionuclide may be used as a tracer of oceanographic processes in the NWM; in fact, Cs-137 Of Rhone river origin has been detected in the Gulf of Lions by several authors. The results reported in this work correspond to various transect experiments in waters of the Catalan Sea and show that: (i) surface salinity measurements confirmed the presence of the Catalan current in...

Contribution a l'étude de l'étrille Necora puber dans le Mor-Braz : données halieutiques, biologiques et pathologiques
Provedor de dados: 5
Autores: Wilhelm, Gwenaëlle.
The velvet swimming crab Necora puber, commonly found on the French coast was an important resource for inshore fishermen of the Mor-Braz sea in Southern Brittany before the production collapsed in 1985. Although there are still many uncertainties as to the reasons for this, we note that the collapse took place after a significant ecological imbalance which locally caused massive mortality of many marine organisms in 1982.  Without being obviously linked to the former point, mortality due to pathological causes was observed in velvet swimming crabs. Seeing the lack of general knowledge about these crabs, this study was designed to acquire data about its fishery and its biology. The first part focused on fleet, fishing effort and yield trends in the...

Ce document présente une étude visant à déterminer le flux de nutriments produits par un élevage de turbots en conditions contrôlées. Les paramètres d'excrétion et de production de fèces ont été abordés en fonction des quantités d'aliment ingéré, en même temps que l'excrétion d'azote corporel. L'étude montre que le turbot est un animal plus économe que la truite arc-en-ciel pour ce qui concerne l'utilisation des protéines. Ceci est explicable par des particularités physiologiques. L'utilisation de modè les "salmonidés" pour l'estimation de l'impact environnemental des piscicultures marines est donc déconseillée.

The MECA 93 oceanographic cruise was carried out in June 1993. The main purpose of the experiment was to understand the action of the main driving mechanisms responsible for the flow variability in the Blanes canyon area (NW Mediterranean) during summer. A domain of about 4000 km(2) including the canyon was covered by RN Hesperides between 17 and 22 June 1993. CTD sampling was performed with characteristic spacing between adjacent stations of 7 to 15 km. The water masses distribution observed during the cruise corresponds to a classical, well-established summer stratification, with typical surface temperatures above 22 degrees C. The thermocline was located at a 40 m depth. The TS diagrams reveal water exchanges across the shelf edge. The surface...

The risks associated with chemical micropollutants in marine waters are much more important today. This is the inevitable consequence of the changes in the means of production and lifestyles in our industrial societies. Confronted with this new situation, it is therefore logical that regulations now include chemical micropollutant concentrations in the assessment and management of water quality in shellfish farms, even though the shellfish waters are still, on the whole, of satisfactory quality in France today.

What is REMORA? REMORA &amp;#8722;REseau MOllusques du département Ressources Aquacoles&amp;#8722; (Aquaculture Resources Department Mollusc Network) is a surveillance network dedicated to the growth of hollow oysters Crassostrea gigas. In the past and in most production areas, observations were made on a regular basis. In 1993, homogenising experimental protocols between the different laboratories involved was decided, as well as using a common initial oyster batch, therefore organizing a network covering all of the French coasts. This network aims at providing, each year, the production's basic characteristics found in main oyster beds (growth reference). It also better characterizes variations and shows potential tendencies.

A brief survey of the sea-food markets for the northern Mediterranean countries is presented, i.e. for Cyprus, France, Greece, Italy, Portugal, Spain and Turkey. Then a comparative study between the markets belonging to the European Union is completed. Three of these countries (France, Italy and Spain) are characterised by a huge deficit in their external sea-products trade. Greece is almost balanced, but Portugal has been importing increasingly more over the last few years. About 45% of the imports come from the European Union. After many years of increasing value, we can now see a stabilisation in the fish price. Since 1977, the consumption of fresh products has been receding in favour of frozen and processed products.

Déterminisme de la croissance de l'huître creuse, Crassostrea gigas, en Bretagne : Méthodologie d'élaboration d'un modèle global.
Provedor de dados: 5
Autores: Dormoy, Jean-marc.
Based on a four years survey of Pacific Oyster Crassostrea gigas growth in the main shellfish farming areas of Brittany from 1989 to 1992, this report is a first attempt to explain the differences between sites and years. The determinist growth models do not suit to this objective, for methodological and practical reasons. Nevertheless, they provide the conceptual basis of a global model by identifying the reliable environmental parameters for a statistical explanation of growth results. The present study proposes a methodology for a global statistical model using the main stages of the ecological and biological processes of shellfish growth. These propositions are based on the analysis of the determinist model's constraints, and also on the identification...

The M(2) tide in the Mediterranean Sea: Dynamic analysis and data assimilation
Provedor de dados: 5
Autores: Lozano, Cj; Candela, J.
The predominant M(2) tide in the Mediterranean Sea is examined using the linearized Laplace tidal equations including the astronomical gravitational potential, the Atlantic tide entering through the Strait of Gibraltar, the Earth tide, the effects of the Earth deformation due to the ocean tide load and bottom friction. The model solution is based on a decomposition of the primitive variables in terms of basis functions associated to the Helmholtz-Proudman potentials. The net tidal power input into the basin is 1.63 10(8) W. Bottom friction dissipation accounts for -0.94 10(8) W. The work done by the bottom deformation due to global (-0.62 10(8) W) and local (-0.07 10(8) W) tide load effects extract energy from the system. The net energy flux into the basin...

Bay of Seine, bay of St. Brieuc and the rade of Brest are the three main fisheries in France. Measurements made on spawners issued from these areas allow to consider two separate reproductive strategies, in these populations. Scallops from St Brieuc spawn during a short period, a sexual rest stage being observed in autumn and winter and recovery occurring in spring. Populations from Brest and from bay of Seine show similar reproductive cycle with a permanent annual sexual activity spawning being scattered from early spring to autumn. This reproductive strategy could explain that recruitment in these fisheries are better than in St Brieuc bay. The variations of the muscle and gonad index are opposite. The muscle acting as storage organ releasing metabolites...

Recent bathymetry and sonar imagery studies of offshore portions of the plate boundary transecting New Zealand allow the first confident mapping of detailed tectonic and sedimentary patterns of the region. Working in late 1993 aboard the R/V L'Atalante of the Institut Francais de Recherche pour l' Exploitation de la Mer (IFREMER), we recorded soundings of a wide swath of seabed to elucidate major structural transitions along the plate boundary. Results of the study, part of the GEODYNZ‐SUD program developed jointly by institutions in France and New Zealand, will be complemented by New Zealand cruises to the Puysegur and Hikurangi margins. The total data set will be processed and interpreted during the next two years.

Evidence for differences in the allozyme thermostability of deep-sea hydrothermal vent polychaetes (Alvinellidae): a possible selection by habitat
Provedor de dados: 5
Autores: Jollivet, D; Desbruyeres, Daniel; Ladrat, Christine; Laubier, Lucien.
Alvinellid polychaetes are, to date, restricted to deep-sea hydrothermal vents of the eastern and the western ridges of the Pacific Ocean. These organisms Live in various sulfide-rich habitats, including the hottest part of the hydrothermal environment (i.e. chimneys). They experience transient anoxia, high levels of heavy metals and H2S, natural radioactivity and temperatures ranging from 5 to 80 degrees C which vary greatly with time. The Alvinellidae, as many vent organisms, have developed specific adaptations to cope with this harsh and unstable environment. Enzyme systems are good markers of the adaptation of ectotherms to temperature, which acts on both enzyme kinetics and protein denaturation. We estimated genetic distances between 11 alvinellid...

Autores: Uysal, Z; Sur, Hi.
Cold water formed on the western continental shelf of the Black Sea in February 1990 was studied. The band of cold water follows the coast and interacts with coastal geometry, resulting in winter phytoplankton blooms particularly along the southwestern coast. Species composition and surface spatial distribution of net phytoplankton (&gt; 55 mu m) showed an apparent species differentiation between the shelf and open ocean plankton. Offshore waters exhibit high diversity indices compared to shelf waters where the intense outburst induced by Chaetoceros sp. occurs. This species of diatom thrived successfully in the cold waters, reaching cell densities &gt; 10(6) cells/l in the vicinity of Sakarya river and its eastward extension. Six different-sized patchy...

Hypercanes: A possible link in global extinction scenarios
Provedor de dados: 5
Autores: Emanuel, Kerry A; Speer, Kevin; Rotunno, Richard; Srivastava, Ramesh; Molina, Mario.
Bolide impacts and large-scale volcanic eruptions have been proposed as possible causes of the massive extinction of life that has occurred episodically in Earth's history. In spite of the catastrophic disruption of the local environment that accompanies bolide impacts and volcanic eruptions, it has been difficult to explain why these events sometimes lead to global extinction of species. We propose that, in some cases, the missing link may be provided by hypercanes, runaway hurricanes that are capable of injecting massive amounts of water and aerosols into the middle and upper stratosphere, where they may have profound effects on atmospheric chemistry and radiative transfer. Hypercanes are theorized to occur when the sea surface temperature exceeds a...

The present paper describes the major results obtained from 1989 to 1992 by the EUROMODEL group in studying the circulation in the Western Mediterranean Sea. Particular emphasis has been given to the physical processes responsible for seasonal and mesoscale variabilities. Observations (in situ and satellite), together with theoretical, physical and numerical models, have been widely used in the course of these studies. Attention has been focused on the dynamics of the northern basin (deep water formation, dynamics of the Northern Mediterranean Current, circulation and shelf/slope interaction in the Balearic Sea) and of the southern basin (Alboran Sea circulation, instabilities of the Algerian Current). The straits dynamics have been studied with particular...

Programme général de recherche sur la nacre. Écophysiologie de l'huître perlière, approche des relations entre  la croissance de l'huître Pinctada  margaritifera  et le milieu dans le lagon de Takapoto
Provedor de dados: 5
Autores: Buestel, Dominique; Pouvreau, Stephane; Tiapari, Jerome; Bougrier, Serge; Chabirand, Jean-michel; Geairon, Philippe; Fougerouse, A.
A study of pearl oysters Pinctada margaritifera growth and mortality was done on a monthly basis between June 1990 and September 1991 in Takapoto atoll (Tuamotu archipelago). Meanwhile, sampling parameters representative of bivalves food showed a remarquable spatial stability whithin the lagoon. The amplitude of temporal variability varied in the order of some days. Carrying capacity appears low : energetic content of particulate material in waters is about 2 joules/liter, ten times lower than in temperate areas. On the opposite, seasonal effect is reduced and particulate food is always available. Oysters rearing conditions were appropriate during the studied period with a low mortality rate and a regular growth in size (from 97 mm to 136 mm). Pearls...

Three-dimensional circulation of a mesoscale eddy/front system and its biological implications
Provedor de dados: 5
Autores: Pinot, Jm; Tintore, J; Lopezjurado, Jl; Depuelles, Mlf; Jansa, J.
The three-dimensional circulation of an eddy/front system is quantified using hydrographic data collected in the Channel of Ibiza, Western Mediterranean, during November 1990. The ageostrophic motion is derived from the quasi-geostrophic omega equation. Maximum upward velocities (approximate to 4 m/day) are diagnosed on the cold side of the front in the vicinity of a cyclonic eddy and coincident with a sub-surface convergence (below 50 m). This upward motion can be explained in terms of advection over isopycnals that uplift in the along-front direction. We also show the relevance of the three-dimensional circulation for the enhanced fertilization observed in the surface layer. Our results establish the importance of the ageostrophic dynamics induced by...

Modélisation du cycle biogéochimique des éléments limitant la production biologique en Manche (N, P, Si)
Provedor de dados: 5
Autores: Hoch, Thierry.
Ce travail présente un modèle du cycle de la matière organique en Manche, à travers les cycles de l'azote, du phosphore et du silicium. Ces éléments ont été choisis car ils limitent principalement la production primaire en Manche.  Dans un premier temps, un sous-modèle physique en boîtes a été' retenu. Grâce au logiciel "ELISE", la Manche a été découpée en 71 boîtes, entre lesquelles les flux d'eau sont automatiquement calculés. A ce modèle de transport horizontal a été couplé un modèle thermo-halin vertical bicouche. Ce dernier simule la température et la salinité dans une couche de surface et une couche de fond, séparées par une pycnocline d'épaisseur nulle. Il permet également le calcul des vitesses d'échange entre les deux couches.  Un couplage a été...

Cultures marines en eaux profondes dans les pertuis charentais : détermination des zones propices à l'élevage d'huîtres Crassostrea gigas
Provedor de dados: 5
La conchyliculture en Charente-Maritime compte 4 500 conchyliculteurs qui exploitent 2800 concessions avec 7 400 emplois directs déclarés. Chaque année, une diminution de 4-5% des concessionnaires parallèlement à une diminution de l'ordre de 1 à 2% des surfaces exploitées est observée. Cette tendance peut s'expliquer par la pyramides des âges des conchyliculteurs et la baisse de compétitivité de l'ostréiculture charentaise vis à vis des principaux bassins de production concurrents (Bretagne, Normandie). La mortalité cumulée dans le Bassin de Marennes-Oléron est supérieure à 50% au cours d'un cycle d'élevage qui atteint maintenant 3-5 ans pour 18 mois dans les années 1970....

Cycle de reproduction naturelle de l'huître creuse Crassostrea gigas
Provedor de dados: 5
Autores: Goulletquer, Philippe.
Since its introduction to French coasts in the 1970s, Crassostrea gigas completes its reproductive cycle—i.e. regular annual recruitment and establishment of natural populations—in only two sectors (Charentes coast and Arcachon Bay). In other areas of Pacific oyster production (Normandy, Brittany, Vendée, Mediterranean), complete gametogenesis may occur, resulting in spawning events and even recruitment in favourable temperatures. Temperature seems to be the main limiting factor for in situ reproduction. Growth and reproduction occur simultaneously. The study of the reproductive cycle of one-year old oysters showed that gametogenesis was asynchronous with high interannual variability and growth appeared to take precedence over reproduction. On the...

La production aquacole dans les pays méditerranéens : synthèse 1992-1994
Provedor de dados: 5
Autores: Lacroix, Denis.
L'aquaculture dans les pays méditerranéens représente 4,9 % de l'aquaculture mondiale (682.000 T. en 1993) et est plus tournée vers la mer (76 %) et les mollusques (68 %) que le reste du monde dominé par l'eau douce (65 %) et les poissons (49 %). Les principales productions sont la moule (38 %) surtout espagnole, l'huître (20 %) surtout française, la truite (16,7 %) la carpe et le dynamique binôme loup-daurade qui a doublé sa production entre 1992 et 1994 (33.000 T.).  Les grands pays producteurs sont aussi grands consommateurs (Europe et Egypte) mais les échanges sont drainés vers le marché le plus rémunérateur qu'est l'Italie. Le développement rapide de l'aquaculture dans cette région au cours des années 1980 commence cependant à s'essouffler notamment...

Modelling the impact of a cultivated oyster population on the nitrogen dynamics: the Thau lagoon case (France)
Provedor de dados: 5
Autores: Bacher, Cedric; Bioteau, Hélène; Chapelle, Annie.
The Thau lagoon (France) is an important site for the cultivation of Crassastrea gigas. The relationship belween the oyster population and the environment was assessed through a model of trophic relationships. The results represent the initial step lowards a more precise assessment of the biological fluxes in the lagoon. This preliminary model was based on the nitrogen dynamics among the following compartments: phytoplankton, zooplankton. oysters. detritus and dissolved inorganic nitrogen in the water column. Two other compartments were also considered in the sediment: detritus and dissolved nitrogen. The model considered the watershed input and seawater exchange belween the lagoon and the open sea . The parameters were estimated from experiments on oyster...

The Delta-O-18 signal of the northward flow of mediterranean waters in the adriatic sea
Provedor de dados: 5
Autores: Stenni, B; Nichetto, P; Bregant, D; Scarazzato, P; Longinelli, A.
The sea-water masses in the Adriatic Sea are fairly well known as regards the classical parameters of salinity, temperature and density. By contrast, the distribution of the oxygen isotopic composition is practically unknown apart from a few isolated measurements. The delta(18)O values of about 600 water samples from vertical profiles in the Adriatic basin were measured to obtain information on the distribution of these values throughout the basin and, if possible, to correlate this variable to the movements and mixing of water masses. The salinity and temperature data are also reported here for a direct comparison of these variables to the isotopic values. Quite positive and homogeneous delta(18)O values, ranging from 1.30 to 1.69 parts per thousand (vs....

Autores: Chryssovergis, F; Panayotidis, P.
The phytobenthos of five stations of the Maliakos Gulf, situated along an eutrophication gradient, comprises 186 taxa, which corresponds to the number of species found in similar gulfs on the Creek coasts. Samplings concerned three types of algal communities: 1) reference communities (in open sea) unaffected by euhophication: 2) modified algal communities in the most polluted and ecologically instable area (catastrophic events); 3) intermediate communities. Rhodophyceae are qualitatively dominant (number of species) in all stations. In the most polluted stations, Ulvophyceae are quantitatively dominant (cover), while Fucophyceae are quantitatively dominant in the non-polluted stations. The ratio Quantitative Dominance/Qualitative Dominance (Tension) of...

Monitoring fresh and brackish water quality around shellfish farming areas with a bivalve embryo and larva simplified bioassay method
Provedor de dados: 5
Autores: His, Edouard; Beiras, Ricardo.
The standard bivalve embryos-larval bioassay method has been modified for monitoring the water quality in an important mussel culture area, La Rochelle Bay. Fertilised eggs from naturally spawned Mytilus galloprovincialis mussels were incubated for 48 h at 18 ± 1 degree C, in different water samples (five replicates) from the bay and its surroundings. The mean percentages of abnormalities, with the 95 % confidence limit, of controls and different water samples were compared. The method was shown to allow the application of the the bioassay to fresh, brackish and marine waters. The assessment of the water quality of the different tributaries to the Bay and that of freshwaters from intensively cultivated marshes close to it, showed that it varied form toxic...

Sur la signification des foraminifères dans les dépôts continentaux
Provedor de dados: 5
Autores: Levy, A; Mathieu, R; Poignant, A; Fernandezgonzalez, M.
The origin of Foraminifera found in continental deposits and endoreic sheets of water poses a problem. This paper presents an inventory of the Foraminifera observed in ancient and recent continental deposits throughout the world. The ecological study of these Foraminifera leads to the differentiation of three groups related to different environments. The first group is indicative of a transitional environment between the margino-littoral area and the continental waters; the second is strictly bound to the margino-littoral biotope; and the third is marine, with a few species capable of tolerating a variable salinity. The presence of some Foraminifera of the last group in the endoreic environments is discussed and leads to the hypothesis that their setting...

Marteiliosis in American oysters Crassostrea virginica reared in France
Provedor de dados: 5
Autores: Renault, Tristan; Cochennec, Nathalie; Chollet, Bruno.
Progeny of Crassostrea virginica oysters, introduced into France in 1992, were reared at 3 different locations. A survey was taken of these young C, virginica oysters during 1993. Histological and electron microscopical examination revealed a parasite interpreted as a Marteilia-like protozoan in 1 oyster. The structure and the initial stages of the developmental cycle of this parasite are described for the first time in American oysters. However, no mature spores were detected. Thus, exact identification of the protozoan is difficult. This study indicates that American oysters could be infected with Marteilia spp, during cohabitation with Marteilia-infected native bivalves in France.

Zooplancton has been sampled in the period 1975-1993, according to a monthly and even fortnightly frequency, in different areas between the south of the North Sea and south Brittany. Sampling was conducted during the whole year until 1983 and then, just on a part of the year. At the same time, water temperature and water salinity were measured. This paper presents variations of larval abundance and hatching time of brown shrimp species (Crangon crangon Linnaeus, 1758) according to the area. Special interest of this paper lies in the fact that it shows the existence of a spring peak of larvae in the south of the North Sea; this spring peak explains the large numbers of juvenile shrimps observed in this region in may and june by others authors.

Mortalités de poissons d'élevage par phytoplancton toxique Camaret (Finistère), automne 1994
Provedor de dados: 5
Autores: Kempf, Marc; Merceron, Michel; Nezan, Elisabeth.
Brown water was observed in Camaret Cove, on 27 and 28 September 1994, because of the massive proliferation of a toxic phytoplankton alga. The densities reached by this alga were considerable: from 1.5 million cells per litre at a point far from the coast to 130 million cells per litre at the height of the efflorescence at the bottom of the bay, in the port's waters. The toxicity of this alga caused deaths in the farms of salmonids in cages set up at this site. The SEMII (IFREMERINRA research facility) experimental farm recorded 100% losses (15-20% on 27 September and the entire remaining stock during the night of 27-28 September), which is around 10 tonnes of fario trout and 0.5 tonne of Atlantic salmon.

The closely spaced stations on the slope permit the observation of the branching of the Malvinas Current near 40 degrees S. The eastern branch returns south, while the eastern one is squeezed along the continental slope, managing to continue northward as far north as 36.3 degrees S. The Brazil-Malvinas (B-M) front has a north-south orientation on the slope and an east-west direction offshore. The B-M front is marked by very strong gradients in temperature and salinity. Fine scale vertical structures and intrusions are numerous in the vicinity of the...

Etude morpho-sédimentaire de la vasière intertidale de Monportail-Brouage (Bassin de Marennes-Oleron) Atlas des Facies
Provedor de dados: 5
Autores: Germaneau, James; Robert, Serge.
L'ouvrage que Verger (1968) a consacré au littoral français en général et au Bassin de Marennes-Oléron en particulier est certainement le plus important document dont nous disposons dans le domaine morpho-sédimentaire. Dans cette étude, l'auteur assimile le littoral charentais aux Wadden de Hollande : cette comparaison est cependant discutable, suivant les arguments développés ci-après qui montrent les principales différences entre vasières littorales charentaises et waddens hollandais.

L'environnement trophique méiobenthique en dehors des nourriceries côtières est-il favorable à l'installation des jeunes soles ?
Provedor de dados: 5
Autores: Amara, R; Bodin, P.
We tested the hypothesis that the absence of newly settled Dover soles (Solea solea) outside the estuarine nurseries of this species is due to a lack of suitable benthic prey. The availability of potential prey was studied at five stations within the distribution area of metamorphosing Dover sole on the northern continental shelf of the Bay of Biscay. Station locations ranged from the offshore spawning grounds to the coastal zone. Suitable feeding conditions for metamorphosing flatfish were found at all five stations. Harpacticoid copepods, the preferred prey of newly settled juvenile sole, are abundant and diversified on the spawning grounds where a majority of Dover sole larvae begin their metamorphosis. Furthermore, harpacticoid copepods were preyed...

L'élevage du bar et de la daurade en France : viabilité économique des systèmes de production
Provedor de dados: 5
Autores: De La Pomelie, Charles.
Three different rearing strategies for sea-bass and sea-bream have rapidly been developed during the last ten years in France: small scale farming in cages in very sheltered areas and industrial farming either off-shore in cages or in-shore in ponds. Production costs of sea-bass in small scale conditions are high, but not above the local market price. Production costs in industrial conditions are much lower and closer to international prices of the European market. Nevertheless, the development of French aquaculture is restricted by the lack of available sites, is faced  to monetary disorders of southern European countries and has to compete with the productions of other Mediterranean countries. Therefore, this activity has to be in constant evolution in...

Contamination of heavy metals in the suspended and surface sediment of the Gulf of Cadiz (Spain): The role of sources, currents, pathways and sinks
Provedor de dados: 5
Autores: Palanques, A; Diaz, Ji; Farran, M.
The Gulf of Cadiz has been affected by contamination from terrestrial mining activities (copper and pyrites) since the times of the Tartesians and Romans. This activity has drastically increased during the past century. Industries implanted during recent decades have supplied another input of contaminants to the marine system. Most of the contaminants are discharged into rivers or in the littoral area, but some contaminated industrial waste was dumped on the continental slope from ships until 1990. Sediment from the continental margin has been sampled to study the heavy metal contamination on the sea bed. The strongest heavy metal anomalies were detected on the continental shelf near the mouths of the Guadiana and Tinto-Odiel Rivers and on the continental...

L'environnement océanique de l'archipel des Tuamotu (Polynésie Française)
Provedor de dados: 5
Autores: Rancher, J; Rougerie, F.
The atolls of the Tuamotu archipelago (South Tropical Central Pacific) are located in the central part of the great anticyclonic gyre where air subsidence leads to an arid climate with high evaporation. The bi-modal system of trade winds created by the existence of dual subtropical high pressure centres (Easter Island and Kermadec Island) drives a global westward drift, the South Equatorial Current, with a speed of 10 cm.s(-1). The zone where the two south trade winds converge (SPCZ) has a strong seasonal variability in position and intensity and controls the eastward counter circulation. During abnormal ENSO events, the counter-circulation is dominant between the equator and 15 degrees S, and the elevated heat content favours active cyclogenesis in French...

Provedor de dados: 5
Autores: Berland, Brigitte R; Maestrini, Serge Y; Grzebyk, Daniel.
Some aspects of the life-cycle have been investigated in Dinophysis cf, acuminata, the dominant species of the genus along the French Atlantic coast, as well as in D, acuta; a few observations have also been made on the Mediterranean species D. pavillardi. Dinophysis cells occur in 2 clearly distinguished sizes. Small cells typically had a theca thinner than large cells, and cingular and sulcal lists were less developed. Both small and large cells were seen dividing, producing 1 to 4 round intracellular bodies. Some of these round bodies in turn contained many small flagellated cells which escaped through a pore and swam rapidly. Their behaviour after release, and how they might give rise to vegetative cells, has not been observed thus far; we do not...

A retrospective study has been carried out on the possible relationships between the spat recruitment of mussels from the Pertuis Breton (France) and some environmental factors at different periods of the year. A significant negative correlation between recruitment and temperature has been found at two periods of the reproductive cycle; the first one coinciding with gametogenesis and the second one taking place just before spawning. But, no relation was noticed with temperature or salinity during the plantonic stage. These results are discussed. An interesting relationship was found between recruitment and "E.T.P.", an index expressing the drying power of air, taking into account temperature, wind, sunshine and moistness.

Tidal currents proved to be the major force determining the changes in the density distribution of meroplankton larvae in the Southern Eight of the North Sea. Path analysis showed that the larvae are strongly correlated with the tide and with tide-coupled environmental factors. Hydrodynamic processes and physical advective factors exert a strong control over meroplankton pattern distribution at different scales.

Hydrographic conditions of the ibiza channel during november 1990, march 1991 and july 1992
Provedor de dados: 5
Autores: Lopezjurado, Jl; Lafuente, Jmg; Lucaya, Nc.
The hydrographic conditions of the Ibiza Channel were studied in successive surveys during November 1990, March 1991 and twice in July 1992. From a hydrographic viewpoint we must emphasize the importance of the intrusion of Modified Atlantic Water (MAW) with its associated front as a result of mesoscale processes, and the presence of the seasonal Winter Intermediate Water (WIW) which fills the entire width of the channel in the form of a layer between 300 or 400 m thick. This water mass affects the dynamics of the Ibiza Channel by a reduction in the exchange, hiding the seasonal characteristics of the Levantine Intermediate Water (LIW), which we consider to be one of the causes of the circulatory change in the channel. The combined action of the different...

The quick evolution of fish farming in Europe, and its development towards the open sea needs suitable farming tools. These tools must withstand the difficult sea states, but they must be easy to use, well adapted to the fish farming and not too much expensive. This book helps the design of such tools. It defines the solicitations of the sea on all the structures, and presents rules and methods to control these solicitations. Here, a structure is composed of a rearing support, a mooring system and equipments. This book describes these components, class them and gives lists of providers. The rearing support can be a cage, a group of cages or a boat. The support can float or to be submersible. The mooring system can be made up ropes, chains, anchors,...

The continental shelf is very narrow and steep to the north, and broader to the South. This shelf is structuraly influenced by the Andes. This area is mainly covered with terrigenous deposits, i.e. muds and sands which are recent on the internal shelf and relict on the external shelf. The sediments, supplied by rivers, reflect the intense erosion of the Andean backland. This erosion can only be reduced in situ by the vegetation cover. Clays are the main component of the fine fraction reaching the sea. Three different clay assemblages are observed: 1) an Andean (illite-chlorite) assemblage, reflecting the proximity of the cordillera; 2) a mid-American assemblage (smectite), which supplies the North Pacific Margin through the Choco counter-current; 3) an...

The seasonality of mesoscale motion in the northern current of the western mediterranean - several years of evidence
Provedor de dados: 5
Autores: Font, J; Garcialadona, E; Gorriz, Eg.
The Liguro-Provenco-Catalan or Northern Current, which contours the continental slope of the north-western Mediterranean Sea, has been described as a permanent flow affected by important variability at different scales. Many observations indicate a higher flux in winter than in summer, while the occurrence of mesoscale events appears to be a common characteristic. The opportunity of examining several years of current meter data at a location close to the inner border of the Northern Current has definitively demonstrated the existence of a seasonality in the mesoscale variability. Although the records do not concern the core of this current, the consistency of the several characteristics we have determined with results found by other authors in the Ligurian...

Catalogue international des activités des flottilles de Manche, approche des interactions techniques
Provedor de dados: 5
Autores: Tetard, A; Boon, M; Bennett, D; Berthou, Patrick; Bossy, P; Casey, J.
This work is the result of collaboration between the English, French, Channel Isles and Belgian laboratories which are involved in a study of the English Channel. Its subject is the activities of fleets and their interactions, and it complements other work on the biogeographical identification of Channel fish and shellfish stocks (published), and on modelling the fleets' interactions as they exploit theresources (in preparation). The concept of a metier is defined as being the use of one fishing gear to catch one or several species targeted during a particular season in a given area. On this basis, 74 metiers were identified during 1989-90. For each metier we give a brief description of the catching gear, the target species and most usual by-catch, the...

Annual geochemical mass balances in waters of the Firth of Clyde
Provedor de dados: 5
Autores: Muller, Fll; Balls, Pw; Tranter, M.
A first-order mass balance of twelve minor and trace elements in the coastal sea area of the Firth of Clyde is presented for the period August 1989-July 1990. It is based on our own four sets of chemical data collected in the Clyde Estuary and Firth of Clyde over that period, complemented by independent information relating to water column hydrography, rainfall, wind speed, river discharge, as well as sewage sludge and dredged material disposed of at sea. Terrigenous inputs were measured or estimated as continuous functions of time. Mean exchange rates with the open shelf were calculated over four periods representative of 77 % of the one-year period considered here. All these fluxes were subsequently converted to monthly values to facilitate...

Marteilia in American oysters Crassostrea virginica reared in France
Provedor de dados: 5
Autores: Renault, Tristan; Cochennec, Nathalie; Chollet, Bruno.
Progeny of Crassostrea virginica oysters, introduced into France in 1992, were reared at 3 different locations. A survey was taken of these young C. virginica oysters during 1993. Histological and electron microscopical examination revealed a parasite interpreted as a Martelia-like protozoan in 1 oyster. The structure and the initial stages of the developmental cycle of this parasite are described for the first time in American oysters. However, no mature spores were detected. Thus, exact identification of the protozoan is difficult. This study indicates that American oysters could be infected with Marteilia spp. during cohabitation with Marteilia-infected native bivalves in France.

Compte-rendu de la campagne "Resubguy 5" (octobre 1994) sur le plateau continental de la Z.E.E. guyanaise
Provedor de dados: 5
Autores: Rose, Joel; Achoun, Joseph.
Depuis octobre 1992 une étude est conduite par le laboratoire "Ressources Halieutiques" de l'IFREMER Cayenne pour analyser les mécanismes de recrutement du stock de crevettes pénéïdes (Penaeus subtilis) du plateau guyanais. En effet, le cycle de cette espèce étant très court, ces mécanismes conditionnent directement les rendements de la flottille industrielle crevettière guyanaise. Les variabilités intra et inter annuelles du recrutement sont considérées comme très fortes, aussi une optimisation de la gestion de cette pêcherie passe par une meilleure compréhension de ces mécanismes et notamment de leurs facteurs de variation. Cette étude s'intègre dans un programme de coopération régionale entre l'IFREMER et le Ministère de l'Agriculture, de l'Elevage et...

Autores: Beiras, Ricardo; His, Edouard.
The effects of Hg concentrations ranging from 0 (control) to 1024 µg 1-1 upon embryogenesis, survival and growth of Mytilus galloprovincialis mussel larvae were investigated . Embryogenesis was abnormal in 50 % of the individuals at 10µg 1-1. The 48 h LC50 for D-shaped, early umbonate, late umbonate and eyed larvae were 51, 164, 322 and 383 µg 1- 1 respectively. The LC50 was an allometric function of ash-free dry weight with exponent b = 0.60. Larval growth was significantly reduced alter 6 d exposure to 4 µg Hg 1-1 and alter 10 d exposure to 2 µg 1-1. No significant differences in lethal or sublethal sensitivity to Hg were found between M. galloprovincialis and previously studied Crassostrea gigas embryos and larvae.

Magmatism in the Garrett transform fault (East Pacific Rise near 13°27′S)
Provedor de dados: 5
Autores: Hekinian, Roger; Bideau, Daniel; Hebert, Réjean; Niu, Yaoling.
The Garrett transform is characterized by recent (zero age) volcanic activity located within the active tectonic domain of the transform valley at depths greater than the 3500 m. This intratransform volcanic activity contributed to the formation of constructional edifices forming ridges (&gt;300 m in height) and small mounds (&lt;20 m in height) built near slivers of serpentinized peridotites. The erupted lavas are depleted mid ocean ridge basalts (MORBs) with low ratios of K/Ti (0.02-0.11), Zr (30-100 ppm), Y (18-50 ppm), and (La/Sm)(N) (0.25-0.60). Their more depleted nature and smaller range of variability for the compatible elements (Ni=70-180 ppm, Mg#=0.58-0.71, where Mg# is the magnesium number (=Mg+2/Mg+2+Fe+2)) are the main points of difference...

Comportement géochimique des herbicides et de leurs produits de dégradation en milieu estuarien et marin côtier
Provedor de dados: 5
Autores: Munschy, Catherine.
The presence and geochemical behaviour of herbicides were investigated in estuarine and marine waters of the French coasts (Seine, Charente, Gironde estuaries and Rhône delta). These organic contaminants were quantified by capillary Gas Chromatography (GC) using Nitrogen-Phosphorus Detecter and identified by GCIMS (Mass Spectrometry). A liquid-solid extraction method using XAD-2 resins was developed,  allowing the analysis of both chloro-triazines and their degradation products in the nanogram per litre (ng.l-1) detection range. Different types of chemicals were identified in the estuarine and coastal waters: triazine, amide and acetanilide herbicides. These compounds are mainly present in the water phase, with less than 1% associated with particulate...

Recent aspects of nutrition in the dinoflagellate Dinophysis cf. acuminata
Provedor de dados: 5
Autores: Berland, Brigitte R; Maestrini, Serge Y; Grzebyk, Daniel; Thomas, Pierre.
No species of Dinophysis has yet been cultured in the full sense. To determine the photosynthetic capability in D. cf. acuminata, the dominant morphotype of the genus along the French Atlantic coast, we took material from natural populations, in some trials by pipetting out single cells, and in others using plankton assemblages enriched in D. cf, acuminata by size fractionation and reverse sedimentation. Inorganic carbon uptake was measured at temperatures from 11 to 23 degrees C and at a light intensity of 400 mu mol photons m(-2) s(-1). Total uptake was proportional to the number of cells and increased linearly with incubation time, the uptake rate showing a distinct maximum at 18 degrees C, while at 23 degrees C being only half this maximum....

The excess of farmed mollusc biomass in some French shellfish-farming basins (Marennes-Oléron basin, Isle of Ré, Isle of Bourgneuf) has been clearly highlighted. This manifests itself as a decrease of growth consistency of the molluscs and an increase in chronic mortality rates not linked to pathogenic agents. To this excess of farmed biomass are added the biomass of oysters or "wild" mussels or biomass linked to abandoned concessions.

The study of soft-bottom macrophytobenthos of the Mediterranean Thau lagoon was carried out in autumn 1986. The total biomass is high (10073 +/- 2006 tDW) and is dominated by Florideophyceae (67 %) and Zostera (22 %). Seven communities have been identified, with the following characteristic species: Solieria chordalis in the deep zone; Ulva rigida, Monostroma obscurum and Gracilaria verrucosa to the northeast; Gracilaria spp. with Sargassum muticum in shellfish breeding zones; Halopitys incurvus to the southwest; and Zostera spp. along the shallow edge. The differentiation of these communities depends essentially on depth, catchment area inputs (fresh water, nutrients, pollutants), sea water flows, hydrodynamism and shellfish breeding activities.

Contrôle de la gamétogénèse des huîtres creuses et plates. Relations "reproduction" et "génétique"

Autores: Gerard, Andre; Naciri-graven, Yamama; Boudry, Pierre; Launey, Sophie; Heurtebise, Serge; Ledu, Christophe; Phelipot, Pascal.
At the end of the 1980s, after two decades of aquaculture research in molluscs, Ifremer initiated its first genetic studies. These new studies quickly revealed the limits of knowledge in aquaculture, particularly in terms of controlling oyster reproduction. This presentation attempts to summarize the available information on genetics in aquaculture. In particular, breeding practices in the 1980s involved populations of broodstock, while genetics requires modern techniques where individuals, not just populations, can be identified. Controlling reproduction at the individual level in oysters raises new questions that existing protocols cannot address, especially in terms of controlling sex determination, individual maturity, spawning synchrony, chemical...

Le Havre du Payré situé au sud des Sables d'Olonne abrite une zone ostréicole de production modeste (1 000 tonnes en 1992). Le réseau de surveillance du milieu marin mis en place par l'IFREMER en 1989 a mis en évidence des épisodes de contamination important sur ce site. Les niveaux atteints en 1992 ont entraîné la fermeture de la zone. Une dynamique s'est alors mise en place entre les diverses Administrations et l'IFREMER a réalisé un suivi intensif sur les trois derniers mois de l'année 1993.

On the seasonal and mesoscale variabilities of the Northern Current during the PRIMO-0 experiment in the western Mediterranean-sea
Provedor de dados: 5
Autores: Alberola, C; Millot, Claude; Font, J.
In the western Mediterranean Sea, the Northern Current is one of the major veins and is formed by the junction, in the Ligurian Sea, of the currents flowing northward along each side of Corsica; it is recognized as an entity along the continental slope as far as the Catalan Sea; surrounding the central zone where dense water formation occurs in winter. The seasonal and mesoscale variabilities of the Northern Current are analysed from a fortnightly hydrological survey carried out off Nice to a distance of similar to 55 km, from October 1990 to July 1991, and from similar to 30 current time series collected as deep as 2000 m, on four moorings set within a similar to 30 km coastal band from December 1990 to May 1991, in the framework of the PRIMO-O...

We present an application of a statistical method based on an original homogeneity test, derived by non-parametric maximum entropy techniques, that analyses ecosystems starting from their species composition. The method is applied to zooplankton data collected in different seasons from three adjacent coastal regions in the Tyrrhenian Sea (Mediterranean), with the aim of quantifying statistically significant differences in species composition which could reflect different environmental features. The analysis revealed significant differences between the study areas. The Gulf of Salerno, a wide mouth embayment open to the flushing of the oligotrophic Tyrrhenian waters, was characterized as a homogeneous area with uniform spatial patterns in copepod...

Origine et état de la population de Crepidula fornicata (Gastropoda Prosobranchia) sur le littoral français
Provedor de dados: 5
Autores: Blanchard, Michel.
The introduction of the limpet Crepidula fornicata on French coasts occurred through a number of stages of unequal amplitude. The two main stages are the result of a) its transportation on the hulls of the Allies ships during WWII, and b) the voluntary introduction of the Japanese oyster Crassostrea gigas in the 1970s. A recent assessment of its distribution shows that it can be found from the North Sea to the Mediterranean shores, resulting in some conflicts, due to its high density.

Processes controlling chemical distributions in the Firth of Clyde (Scotland)
Provedor de dados: 5
Autores: Muller, Fll; Balls, Pw; Tranter, M.
A total of 28 chemical variables were measured on water samples taken on an approximately longitudinal section of the Firth of Clyde in August 1989, November 1989, March 1990, July 1990 and March 1991. The data were integrated in a study of the overall processes acting on these variables. The sampling section crossed two mixing zones, i.e. the Clyde Estuary Plume (30 &lt; S &lt; 32) and the Clyde Sea (32 &lt; S &lt; 34), with mixing times of 4-25 days and 60-150 days respectively. The interpretation of the distributional data was complicated in July 1990 by the penetration of an ''older'' water mass originating from one of the five sealochs bordering the Firth of Clyde. Heterogeneous reactions within the Clyde Estuary Plume generally modified the export...

Mean sea level and surface circulation variability of the Mediterranean Sea from 2 years of TOPEX/POSEIDON altimetry
Provedor de dados: 5
Autores: Larnicol, Gilles; Le Traon, Pierre-yves; Ayoub, N; Demey, P.
We describe the circulation and mean sea lever variations of the Mediterranean Sea from 2 years of TOPEX/POSEIDON altimetric data. It is first shown that the response of the Mediterranean Sea to atmospheric pressure forcing is close to an inverse barometer (except at high frequencies) which means that the adjustment is accompanied by a flow through the Straits of Sicily and Gibraltar. We then use TOPEX/POSEIDON to study the mean sea level variations, representing steric effects and integrated large-scale changes of the mass of the Mediterranean Sea. We observe an annual cycle with a fast drop during winter, Steric effects account for about half of the observed variations. The remaining signal is believed to be driven by evaporation minus precipitation (E -...

Diagnostic technico-économique et aide à la gestion d'entreprise en aquaculture
Provedor de dados: 5
Autores: Calleja, P; Paquotte, Philippe.
Formal accounting sheets usually turn out being unappropriate to identify the technical or managerial elements causing the financial situation of an enterprise and to imagine the future of that enterprise as well. That is the reason why, as it has been widely developed in agriculture, a technico-economic approach linking the physical flows related to the activity of the enterprise and the resulting financial flows should be a better answer to the need of vigilance on husbandery practices and to the need of projection in the future. The realization of a computerized simulation tool taking into account some relevant technical, biological and economic criteria makes it possible to assess the consequences of investment decisions on the cash-flow and on the...

Variability of the northern current off Marseilles, western Mediterranean-sea, from February to June 1992
Provedor de dados: 5
Autores: Conan, P; Millot, Claude.
A hydrological transect was performed on seven occasions from February to June 1992 in the coastal zone off Marseilles, a region of the western Mediterranean Sea where such data were not yet available. This lack of information is surprising, especially if one considers the large amount of data already collected both further seawards and in neighbouring regions such as the Ligurian and the Catalan Seas. The time interval between the transects (one week to one month) does not permit a distinction between mesoscale and seasonal variations, but the fine space interval between the casts (3-4 km) and the length of the transect (similar to 45 km) provide significant information on the characteristics of the Northern Current (NC) when it penetrates into the Gulf...

Diagenetic evolution of the dop facies from the atlantis-ii-deep (red-sea) - evidence of early hydrothermal activity
Provedor de dados: 5
Autores: Anschutz, P; Blanc, G.
The 23,000 year old sediments of the Atlantis II Deep rest on a basaltic substratum and are overlaid by a dense and hot brine pool. The facies of the lower sequence of the West basin consists essentially of bioclastic and detrital particles (DOP facies). The primary calcite and aragonite of planktonic tests of the DOP facies have been transformed into Ca-, Mg-, Mn-, and Fe-carbonate solid solutions. Pyrite amounts to about 1-2% (wt) at the bottom of the sedimentary series, and as much as 20% (wt) in the upper part of the sequence. These high iron - and manganese - earing minerals are the product of early diagenetic processes in an environment favourable to bacterial activity, to which biogenic and detrital particles, organic matter, and iron and manganese...

SCORPIONS, SCORPIONISM, LIFE HISTORY STRATEGIES  AND PARTHENOGENESIS
Provedor de dados: 79
Autores: LOURENÇO,W.R.; CUELLAR,O.
Recently public health problems resulting from scorpion stings have shown an alarming increase in various tropical and subtropical countries such as Brazil, Mexico, Tunisia and Morocco. In some regions of Brazil, particularly in the States of Minas Gerais, São Paulo, Bahia, Goiás and the Federal District, more than 6000 scorpion stings with over 100 deaths were reported during a three-year period. In this paper, we attempt to demostrate the effects of human activities on the environment and their consequences on the distribution of dangerous species of scorpions. This topic is discussed in relation to the evolutionary ecology, life history strategies and asexual reproduction of scorpions.

THE EFFECT OF A POLYDNAVIRUS OF APANTELES GALLERIAE  ON THE HEMOLYMPH PROTEINS OF HOST GALLERIA MELLONELA
Provedor de dados: 79
Autores: BROCHETTO-BRAGA,M.R.; PALMA,M.S.; RIBEIRO,J.C.; GOBBI,N.
The presence of a polydnavirus in the ovary of the microhymenoptera Apanteles galleriae was detected. This wasp parasites the larvae of the wax moth Galleria mellonella. To study the possible viral effects on the total protein of G.mellonella, hemolymph extracts of the ovary calyxes of parasitized A. galleriae were injected into 6th and 7th instar cells of G.mellonella larvae. Protein profiles on polyacrilamide gel electrophoresis containing sodium dodecyl sulfate (SDS-PAGE) of host cell extracts showed a suppression of several protein bands when infection occurred in the 6th instar. However, in the 7th instar, parasitism caused an amplification in the synthesis of most proteins with some changes in the electrophoretic profile.

DETOXIFICATION OF SNAKE VENOM USING IONIZING RADIATION
Provedor de dados: 79
Autores: ROGERO,J.R.; NASCIMENTO,N.
It is generally recognized that energy absorbed from ionizing radiation (gamma rays) can inactivate biological material in two ways. A direct effect occurs when the primary event, i. e., ionization, is produced in the molecule itself. This is the case when a compound is irradiated in dry state. When a compound is irradiated in a solution, the indirect effect joins the direct(9). Since water is the most abundant constituent of biological material, it is important to consider the species produced by excitation and ionization of water itself, and the reaction of these species with the target molecules of biological importance. This indirect effect results from the reactions among the studied molecules and the products of radiation interaction with water or...

SERUM BIOCHEMICAL DETERMINATIONS OF PROPOLIS-TREATED RATS
Provedor de dados: 79
Autores: SFORCIN,J.M.; FUNARI,S.R.C.; NOVELLI,E.L.B.
Ethanolic extracts of the bee glue, a resinous substance collected by honeybees called propolis, have been widely used in folk medicine since ancient times. Antibacterial, antifungal and thus antiseptic properties may represent the basis for the historical and present use of these extracts in dermatology, against inflammatory conditions and common colds. This work was carried out in order to verify possible biochemical alterations in some seric parameters of propolis-treated rats. It was shown that propolis possesses an antioxidant property and its administration did not affect either amylase and alanine transaminase activities or total protein concentration.

Eighty-four patients bitten by venomous snakes were studied retrospectively at the School of Medicine of Marilia from January 1990 to August 1994. The majority of these patients were rural workers, 65 (77.38%) males and 19 (22.62%) females, aged eight to seventy-five. Forty-three (51.19%) patients were diagnosed as having been bitten by snakes of the genus Bothrops and 41 (48.81%) by Crotalus. Fifty-eight patients (69.04%) were bitten in the legs and 26 (30.96%) in the arms. January, March, April and November were the months of higher incidence of bothropic envenomations, while crotalic envenomations were not recorded only in August and September. This study showed that the prevalence of crotalic envenomations in Marilia was higher than that of any other...

Honey, royal jelly, propolis, materials produced and/or gathered by Apis mellifera honeybees have been used as food and medication for centuries(6,7,8). Although extensively used, honeybee products have become a matter of interest and controversy for years. Honey, well known as healthy and natural food, has shown therapeutic properties in the treatment of digestive, respiratory, cardiac and rheumatic disorders, among others(4). Several studies have reported honey's immunological, antibacterial, antiinflammatory, antipyretic properties besides its importance in terms of energy intake(3,5). Furthermore, honey has proved to possesses wound healing and analgesic actions(1,2). Honey and propolis are also known to be effective in the treatment of respiratory...

A comparison among the profiles of molecular exclusion chromatography in Sephadex G 100 column of venoms from Apis mellifera adansonii and Africanized honeybees revealed unique peaks which might be used to identify these populations. The venoms from hybrid populations resulting from the reciprocal mating of Apis mellifera adansonii and Africanized honeybees presented unique peaks, probably resulting from a synergistic effect between the parental genomes. The occurrence of characteristic peaks in venoms of hybrid populations might be used to identify these populations as well as to distinguish them from their parents.

A coral-eating barnacle, revisited (Cirripedia, Pyrgomatidae)
Provedor de dados: 16
Autores: Ross, Arnold; Newman, William A.
The coral-eating barnacle Hoekia monticulariae (Gray, 1831), the only internal parasite among the Thoracica described to this day, is characterized by an irregularly-shaped shell nestled cryptically between the polyps of the hermatypic coral Hydnophora Fischer, 1807, which occurs throughout most of the Indo-West Pacific. Because of its protean form, cirripedologists have failed to appreciate the diversity of taxa related to Hoekia, , a presumed monotypic genus. We describe seven new species divided between Hoekia and three new genera, Eohoekia, Parahoekia, and Ahoekia for which the Tribe Hoekiini is proposed. As in other pyrgomatids, calcareous overgrowth by the coral is inhibited around the edge of the wall and aperture. But in Hoekiini a pseudopolyp,...

Zoölogische diversiteit in Nederland
Provedor de dados: 16
Autores: Koomen, P.; Nieukerken, E.J. van; Krikken, J.
Op basis van een enquête onder specialisten wordt een overzicht gegeven van de huidige kennis van de Nederlandse meercellige dieren. De eencelligen worden in een aanhangsel besproken. Thans telt de Nederlandse fauna ongeveer 25.200 soorten, waarvan ca. 24.400 soorten inheems zijn. Inclusief de te verwachten soorten is het totaal bijna 35.000. Daarnaast zijn er ruim 1100 soorten eencellige dieren. Echt tot ons land beperkte soorten zijn er niet, wel enkele endemische ondersoorten. De fauna ondergaat grote veranderingen, die niet alleen door natuurlijke veranderingen te verklaren zijn. Van ongeveer 600 soorten is bekend dat ze uit ons land verdwenen zijn, maar naar verwachting zijn het er veel meer. De achteruitgang is vooral groot bij enkele groepen...

Biodiversiteit in theorie en praktijk
Provedor de dados: 16
Autores: Hengeveld, R.
Biodiversiteit is een recent en nog slecht gedefinieerd begrip. Doorgaans wordt het op tweeërlij wijze opgevat en gemeten. De eerste betreft het loutere aantal soorten in een gebied, ongeacht hun identiteit of biologische eigenschappen. De tweede wijze betreft juist de biologische variatie in eigenschappen zelf, maar deze variatie wordt doorgaans niet gekwantificeerd. In dit artikel wordt het uitwaaieringsproces beschreven van soorten die in de loop van de evolutie op steeds andere aspecten van de variatie in het milieu zijn gaan reageren. Bovendien wordt een suggestie gedaan om de afname van de biodiversiteit te meten door soorten te tellen, niet ongeacht hun eigenschappen, maar juist naar bepaalde waarden die deze eigenschappen aannemen. Er is,...

North-eastern Atlantic and Mediterranean species of Cornulariidae Dana, 1846 (Anthozoa: Stolonifera) with the description of a new genus
Provedor de dados: 16
Autores: López-González, P.J.; Ocaña, O.; García-Gómez, J.C.; Núñez, J.
The North-eastern Atlantic and Mediterranean species of the family Cornulariidae are re-examined and taxonomically revised. This family is mainly characterized by the absence of sclerites. Up to now, only one genus, Cornularia Lamarck, 1816, has been assigned to the family. Studies of the internal and external anatomy of the European species of Cornulariidae, carried out for the first time on a comparative basis, leads us to propose a new genus, Cervera. New combinations of the species included in the family are proposed. The main characters of Cervera gen. nov. are the presence of a fine chitinous periderm, various communication canals in the stolons and the absence of a additional chitinous layer that covers the periderm. Cornularia atlantica Johnson,...

Arthropod pattern theory and Cambrian trilobites
Provedor de dados: 16
Autores: Sundberg, Frederick A.
An analysis of duplomere (= segment) distribution within the cephalon, thorax, and pygidium of Cambrian trilobites was undertaken to determine if the Arthropod Pattern Theory (APT) proposed by Schram &amp; Emerson (1991) applies to Cambrian trilobites. The boundary of the cephalon/thorax occurs within the predicted duplomere node 1 (duplomeres 4 or 6). The boundary between the thorax and pygidium generally occurs within node 2 (duplomeres 11—13) and node 3 (duplomeres 18—20) for corynexochids and ptychopariids, respectively. This boundary occurs within field 4 (duplomeres 21—n) for olenellids and redlichiids. The termination of the body generally occurs within node 3 for corynexochids and within field 4 for olenellids, redlichiids, and ptychopariids. In...

Wat is natuurontwikkeling?
Provedor de dados: 16
Autores: Londo, Ger.
Sinds de mens zich in het Neolithicum door middel van landbouw en veeteelt losmaakte van de ecosystemen waarvan hij tot dusver deel had uitgemaakt als natuurlijk element van de grote fauna, ging hij een steeds grotere invloed op de natuur uitoefenen. Het natuurlijke landschap van bossen en hoogvenen maakte geleidelijk plaats voor het halfnatuurlijke landschap. Op zijn beurt veranderde het halfnatuurlijke landschap in het moderne cultuurlandschap. Restanten van het vroegere (nagenoeg) natuurlijke landschap en van het halfnatuurlijke landschap werden objecten van het natuurbehoud. Momenteel wordt getracht het bovenvermelde proces van een steeds toenemende menselijke beïnvloeding plaatselijk om te draaien door (voormalige) cultuurgrond in natuur om te vormen....

Contrary to published descriptions, the poorly known New Guinea genus Dryadorchis Schltr. neither has a footless column, nor an immobile labellum. The merger of Dryadorchis with Thrixspermum Lour., as proposed by Clements, Wallace, and Jones, is not justified. Chamaeanthus singularis J.J.

Key to the genera of Orchidaceae of New Guinea
Provedor de dados: 16
Autores: Schuiteman, A.
With roughly 2300 known species in 133 genera (see Appendix), New Guinea is the richest area in the palaeotropics as far as orchids are concerned. Up to the present the only useful key with which orchids from New Guinea can be identified to genus level is that published by J.J. Smith in 1934. This key is now obsolete in several respects because of changes in nomenclature and in taxonomic views. Besides, Smith’s key is not always very practical; frequent use is made of characters which are difficult to evaluate in preserved material or which easily may be misunderstood. Yet, many orchid genera can be recognized at a glance, a fact which is not at all obvious from most keys that I have seen.

Reintroduction of Orangutans: A New Approach. A Study on the Behaviour and Ecology of Reintroduced Orangutans in the Sungai Wain Nature Reserve, East Kalimantan Indonesia
Provedor de dados: 16
Autores: Fredriksson, Gabriella.
The reintroduction of ex-captive orangutans Pongo pygmaeus) is part of a comprehensive conservation program to preserve this species and it’s habitat. During the last decades the orangutan has been under severe threat throughout it’s range- Northern Sumatra, Kalimantan and East Malaysia- due to massive habitat destruction, hunting pressure and the illegal pet trade. The predecessor of orangutan reintroduction was ‘rehabilitation’ of the ex-captive apes. Rehabilitation has been described as “the training of behaviourally inadequate animals in skills which allow them to survive with greater independence” (Hannah and McGrew 1985). The first attempt to rehabilitate ex-captive orangutans came from Mrs. Barbara Harrisson in the 1960s in Sarawak (Harrisson 1962)...

Among the treasures of the Komarov Botanical Institute at St. Petersburg is a folio known as “Thunberg Icones Plantarum Japonicarem (ineditae)”. This volume contains 305 fine drawings, washed grey apart from a few that are in watercolours. Actually, known can hardly be said; like so many bound collections of pictures only a few of the institutions’ staff members with a special interest in history know of its existence, still less have ever seen it. Good photographs of these drawings (natural size, that is 37 x 26 cm) form the kernel of this work. Added are Maxomiwicz’s notes on the drawings (the great Russian 19th century botanist Maximowicz with his special interest in the East Asian flora brought some important historical collections on Japanese botany...

Wilde flora en natuurontwikkeling in Flevoland
Provedor de dados: 16
Autores: Bremer, Piet.
Na het droogvallen van de Noordoostpolder (1941/42) ontstond een uitgestrekt moerasgebied. Tijdens de inrichting werd op de Rotterdamse Hoek een plasje aangelegd bedoeld als rustgebied voor eenden. Pas bij de inrichting van Oostelijk Flevoland werd vanaf 1965 natuurontwikkeling op grotere schaal toegepast. In deze polder werden zeven natuurgebieden aangelegd. Waterhuishoudkundige ingrepen waren hierbij uitgangspunt; dijkjes werden aangelegd en het waterpeil kunstmatig opgevoerd met dammen en stuwen, wat leidde tot de ontwikkeling van natte rietlanden (Kamperhoek, Harderbroek) of natte graslanden (Kievitslanden, Ellerslenk). Alleen laatstgenoemde gebied kreeg een botanische doelstelling. Afwijkend was de aanleg in 1970 van een heggenlandschap midden in...

Provedor de dados: 16
Autores: Darling, D.C.
Two new species of Krombeinius from Indonesia are described and illustrated, K. kubah from Java and K. dictyon from Sulawesi. In addition, K. eumenidarum Bouček and K. megalaspis (Cameron) are redescribed to allow comparison with the closely related species, K. dictyon and K. kubah, respectively. The first-instar larva of K. kubah is described from an aculeate wasp cocoon associated with the holotype and these planidia are compared with those known for Perilampidae and Eucharitidae. The new species are accommodated in the key to species and phylogenetic analysis of the genus presented in Darling (1988) and the biogeographic implications of the phylogeny are discussed.

De implementatie van het Biodiversiteitsverdrag van Rio de Janeiro is een belangrijke taak voor het Nederlandse natuurbeleid. In 1990 bracht het Ministerie van Landbouw, Natuurbeheer en Visserij het Natuurbeleidsplan uit. De hoofddoelstelling van dit plan is behoud van biodiversiteit via de realisatie van de Ecologische Hoofdstructuur (EHS). De EHS bestaat uit kerngebieden, natuurontwikkelingsgebieden en verbindingszones. Door betere ruimtelijke voorwaarden te scheppen kan het beheer van natuurterreinen efficiënter worden. Op dit moment is de EHS vooral een strategisch concept. Concrete doelstellingen voor de terreinen binnen de EHS zijn nodig om het te operationaliseren. De eenheid waarin en ruimtelijke schaal waarop diversiteit wordt uitgedrukt moet...

Autores: Vertegaal, Kees (C.) T.M.; Ellers, Jacintha.
Natuurontwikkeling in de duinen is een veelvormig verschijnsel. Vaak gaat het in feite om herstel van waardevolle onderdelen van het in grote lijnen nog vrij intacte duinlandschap. Beginsituaties zijn volgens de indeling van Ger Londo¹ meestal ‘matig gedenatureerd’. Doelen kunnen betrekking hebben op ontwikkeling van bepaalde waardevolle onderdelen van het duinlandschap (bijvoorbeeld gekerfde zeerepen, slufters, natte duinvalleien, duinzoom) en op belangrijke sturende processen, zowel abiotisch (bijvoorbeeld verstuivingen) als biotisch (bijvoorbeeld herintroductie van grote zoogdieren). Het onderscheid tussen herstel en ontwikkeling is vaak niet scherp te maken. Echte ‘nieuwbouw’ van complete duinecosystemen speelt vooral in cultuurland aan de...

Chromosomal basis for a bilateral gynandromorph in Pycnogaster inermis (Rambur, 1838) (Orthoptera, Tettigoniidae)
Provedor de dados: 16
Autores: Barranco, P.; Cabrero, J.; Camacho, J.P.M.; Pascual, F.
Morphological and cytogenetic analyses of a spontaneous gynandromorph of Pycnogaster inermis, found in a natural population in the Spanish Sierra Nevada, have shown that the left side was male and the right side female, with almost perfect bilateral symmetry. Ventral valves of the ovipositor were very short, appearing as two spurs; dorsal valves were longer but still shorter than normal. The specimen had an apparently normal testis on the left side and a well-developed ovary on the right side. Cytogenetic analysis revealed the presence of 2n = 28 + X0 chromosomes in the testis and 2n = 28 + XX in the ovary, the same as standard males and females, respectively, of this species. This suggests that the gynandromorphism occurred at a very early developmental...

A new genus and species of sea anemone, Onubactis rocioi gen. et spec. nov. (Actiniidae) is described from the Atlantic coast of the southern Iberian Peninsula. The main features of Onubactis rocioi are: a smooth to corrugate scapus, a delicate scapulus provided with a ruff of non-adherent papillate outgrowths, absence of acrorhagi, more mesenteries distally than proximally, a weak diffuse sphincter, and presence of numerous spirocysts in the pedal disc. The new genus is discussed in relation to five other genera which are characterized by a distal ruff of columnar outgrowths: Actinostella Duchassaing, 1850; Oulactis Milne-Edwards &amp; Haime, 1851; Saccactis Lager, 1911; Isocradactis Carlgren, 1924; and Isoulactis Carlgren, 1959.

Four species of Copepoda (three Siphonostomatoida, one Poecilostomatoida) are recorded as associates of shallow-water echinoids, from Curaçao, St. Martin, Jamaica, Puerto Rico, and the Bahamas. The siphonostomatoids Chelacheres longipalpus and C. optans belong to a new genus and species of the family Asterocheridae. Another species of the same family is provisionally attributed to Asterocheres simulans (T. Scott, 1898), previously recorded from Europe only. A fourth species, of the genus Pseudanthessius (family Pseudanthessiidae), belongs to a new species, Ps. exilicornis.

Over de standplaats van Appelmos (Bartramia pomiformis Hedw.) en het voorkomen van enkele ‘bosmossen’ in het open duin
Provedor de dados: 16
Autores: Bruin, Kees (C.) J.W.
The moss Bartramia pomiformis, which has become very rare in Holland (see Fig. 1), was found in 12 localities in the sand dunes on the Isle of Texel. All localities are situated on steep, north-facing slopes that clearly showed terracing, which is caused by the activities of rabbits and grazing sheep. Bartramia grows on the steep banks of these terraces, in a vegetation that is dominated by bryophytes and lichens. Four releves of vegetations with Bartramia are presented in Table 1. It is pointed out that Bartramia requires a habitat that on the one hand offers sufficient protection against the desiccating influence of direct sunshine and wind, but which on the other hand still receives enough light to enable good growth of the moss. This kind of habitat is...

Provedor de dados: 16
Autores: Welzen, Peter C. van; Bulalacao, Lolita J.; Ôn, Tran van.
Trigonopleura, a genus from W Malesia, has three species, the widespread T. malayana (Malay Peninsula, Sumatra, Borneo, Sulawesi) and the two endemic species T. dubia (Philippines) and T. macrocarpa (Sarawak, Kuching). The species differ slightly from each other in leaf size, colour, and margin, flower and fruit size, fruit wall thickness, and aril size. A phylogenetic analysis was not performed, but it is argued that both endemic species split off separately from T. malayana. Trigonopleura is probably related to Chaetocarpus, in particular to C. castanocarpus. Probably, Chaetocarpus is a paraphyletic group of species and will be monophylitic when united with Trigonopleura, but this will need thorough phylogenetic research. Here, both genera are kept...

Provedor de dados: 16
Autores: Wilde, W.J.J.O. de.
In this paper an account is given of all names in the genus Myristica Gronov. for New Guinea, including 71 new species, subspecies or varieties and 4 new names either by new combination or new rank. Sinclair (1968) accepted 40 species names with 7 varieties, Foreman (1974, 1978) admitted 45 names (38 species and 8 varieties). In the present census I have 95 species and 31 taxa of infraspecific rank, reflecting a more refined species definition as well as the intensified field collecting of the last decades. A key is given, based on male and female flowering and fruiting specimens.

Dr. Ruurd (“Ru”) Dirk Hoogland, born 24 July 1924 in Leeuwarden (The Netherlands), died still rather unexpectedly on 18 November 1994 in a hospital in the neighbourhood of Paris, just 8 days after an operation. The later years of his life were overshadowed by a serious illness. Ru did not accept this, even not those last weeks when he could hardly chew. Everyday he went to the Laboratoire de Phanérogamie and worked, and in March and April 1994 he even made a collection trip to Tahiti followed by a herbarium trip to Australia. Ru studied at the universities of Groningen and Leiden. He got his Ph.D. in Leiden in 1950 on the thesis “A Revision of the Genus Dillenia”. His promotor was Prof. Dr. H.J. Lam. He started his career as a botanist in the service of...

Provedor de dados: 16
Autores: Turner, H.
A taxonomic revision of Arytera Blume is presented, together with a cladistic analysis. On the basis of this analysis, a new genus is recognised, Mischarytera gen. nov., to accommodate the species A. bullata, A. lautereriana, and A. macrobotrys. The necessary new combinations are made. A new classification for Arytera at infrageneric level, also based on the cladistic analysis, is given. Two sections are recognised, Azarytera and Arytera; the latter is further divided into three subsections, Arytera, Distylis subsect. nov., and Pacifica subsect. nov. One new species is described ( A. nekorensis) and one new combination is made ( A. neoebudensis).

Palaeozoic microfossils from Orphan Knoll, NW Atlantic Ocean
Provedor de dados: 16
Autores: Hinte, J.E. van; Ruffman, A.; Boogaard, M. van den; Jansonius, J.; Kempen, T.M.G. van; Melchin, M.J.; Miller, T.H.
Orphan Knoll is an isolated, drowned continental fragment 550 km northeast of Newfoundland. The top of Orphan Knoll stands at 1800 to 2000 m and is marked by a series of protruding mounds. Dredging at the base of one of the mounds in 1971 obtained a suite of fossiliferous limestone pebbles that are interpreted to reflect nearby bedrock. The shallow marine limestone facies include mudstone, wackestone, packstone, and grainstone. The pebbles yielded Late Ordovician, Silurian and Devonian conodonts, as well as Ordovician/Silurian scolecodonts, chitinozoans and graptolites. Similarly, sponge spicules suggest the presence of Late Ordovician as well as Middle Devonian material including a Silicunculus-type of hexactinellid anchoring basalia and an octactine...

Eudendrium pocaruquarum n. sp. (Hydrozoa, Eudendriidae) from the southeastern coast of Brazil, with remarks on taxonomic approaches to the family Eudendriidae
Provedor de dados: 16
Autores: Marques, Antonio C.
Eudendrium pocaruquarum, a new species of athecate hydroid referable to the family Eudendriidae, is described from the state of São Paulo, Brazil. The species is very similar to the widespread Eudendrium ramosum (Linnaeus, 1758), differing from it in the smaller size of the large microbasic euryteles. Longstanding problems in the systematics of eudendriid hydroids are noted, and the inadequacies of many early descriptions of species are discussed. The nematocysts provide a supplementary character for discrimination of species of Eudendrium, although information on the cnidome appears to have been sometimes misinterpreted in literature.

Morphological and allozyme studies of midwife toads (genus Alytes), including the description of two new taxa from Spain
Provedor de dados: 16
Autores: Arntzen, J.W.; García-París, M.
Allozyme variation in 31 to 50 presumptive loci of 12 populations of European midwife toads of the genus Alytes show appreciable genetic divergences (DiNe from 0.29 to 0.72) among four groups. These groups correspond to A. cisternasii Boscá, 1879, A. obstetricans (Laurenti, 1768), A. muletensis (Sanchiz &amp; Adrover, 1979), and a new species from the Betic mountains described here as A. dickhilleni n. sp. Smaller divergences among geographic groups of populations of A. obstetricans (up to DNei = 0.17) support the existence of three geographic units in Europe corresponding to the previously recognized subspecies A. o. obstetricans and A. o. boscai Lataste, 1879, plus a third one described here under the designation of A. o. almogavarii n. ssp.

Short-chain unsaturated chiral methyl carbinols are identified as a new class of lepidopteran pheromone components. The natural female-produced pheromone of the banded apple pigmyStigmella malella (=Nepticula malella) (Stainton) (Lepidoptera: Nepticulidae) was identified to be a mixture of (S)-(E)-6,8-nonadien-2-ol and (S)-(Z)-6,8-nonadien-2-ol. For monitoring traps, a 10:3E:Z blend at 100–1000 µg is recommended. It is suggested that pheromones with similar structures may be specific to Nepticulidae and other related microlepidopteran families.

The text part contains an update taxonomic arrangement of the plates, Errata and addenda to vol. 1 and 2, references to literature, a glossary of terms, and a rather extensive parts devoted to nomenclature and typification of species and subspecific taxa as well as a reevaluation of sectional names. New taxa are validly published in an appendix, followed by references and an index to all three volumes. It is very satisfactory to see that the present series continues, and is able to maintain its very high standard.

Leaf anatomy of Harpullia, Majidea, and Conchopetalum (Sapindaceae)
Provedor de dados: 16
Autores: Buijsen, J.R.M.
The leaf anatomical characters of Harpullia and the related genera Majidea and Conchopetalum are described in detail. Harpullia and Majidea both have stellate hair tufts together with solitary unicellular hairs, in Conchopetalum stellate hair tufts are absent. A high variability below the species level is reported for several leaf epidermal characters. Other leaf anatomical characters such as the hypodermis, sclerification of the bundle sheath extensions, and the presence of secretory idioblasts and idioblastic sclereids also show a considerable variation. Characters with a higher diagnostic value within Harpullia are the type of stomata and in certain species the presence of idioblastic sclereids in the mesophyll. Based on leaf anatomy the subgenus...

Rijstgras [Leersia oryzoides (L.) Swartz] in het Middennederlandse rivierengebied
Provedor de dados: 16
Autores: Kerkhof, Dick; Duistermaat, Leni (H.).
Leersia oryzoides has declined probably less dramatically than was assumed.² This freatophitic species is easily overlooked because its vegetative parts appear late in summer, and its inflorecences come out of the sheaths in warm summers only. In the region Vijfheerenlanden (province of Zuid-Holland) it is found in 29 kilometer squares in the period 1992—1994. Its occurrence seems to be related to the presence of bare places and steep banks of ditches with a southern exposition, as well as of seepage water. It is likely that its present distribution is larger than presented in Figure 1.

It is not the custom to review publications not directly pertaining to the Malesian flora. However, as most of the lowland species of grasses have a wide distribution from Africa through India to Malesia and beyond, the value is surpassing the geographical limits of this flora. Firstly, the present work is a thorough updating of a previous treatment of the grasses for Sri Lanka by Seneratna, ‘Grasses of Ceylon’ (1956). Secondly, by having descriptions, it is a useful companion to Bor’s ‘Grasses of Burma, Ceylon, India and Pakistan’ (1960). It is a compilation of contributions by various authors (W.D. Clayton, G. Davidse, F. Gould, M. Lazarides, T.R. Soderstrom), causing a rather variable ‘flavour and phrasing’ retained as best as possible by the final...

Lissodendoryx species of the Indo-Malayan Archipelago (Demospongiae: Poecilosclerida)
Provedor de dados: 16
Autores: Hofman, Caroline C.; Soest, R.W.M. van.
A brief history of the genus Lissodendoryx Topsent, 1892 is given and the Indo-Malayan representatives are described based on material collected by the Siboga Expedition (1899-1900) and the Indonesian-Dutch Snellius II Expedition (1984-1985), on reexamination of previously described specimens from the area, and on the literature. Previously, ten species assigned to Lissodendoryx were reported from this area. Two of these, L. baculata Topsent, 1897 and L. tawiensis Wilson, 1925, do not conform to the presently employed definition of the genus Lissodendoryx. One, L. sinensis Brøndsted, 1934, is considered a junior synonym of L. ternatensis (Thiele, 1903). L. grata (Thiele, 1903) is a valid species of Lissodendoryx, with L. oxytes De Laubenfels, 1954 of the...

Neocyclops (Protoneocyclops) ferrarii, a new species of cyclopid (Copepoda: Cyclopoida) from Belize, with remarks on the morphology of the genus Neocyclops
Provedor de dados: 16
Autores: Falavigna da Rocha, Carlos Eduardo.
Neocyclops (Protoneocyclops) ferrarii sp. n. is described from Candy’s Pond, Twin Cays, Belize. It is morphologically closest to N. (P.) wellsi Petkovski, 1986 from Mozambique and N. (P.) herbsti Petkovski, 1986 from the Red Sea. Pediger 1 in Neocyclops is distinct although reduced and often concealed beneath the cephalic shield. Specimens of Neocyclops (N.) vicinus and N. (N.) medius showed the same condition, warranting the supposition that the free pediger 1 is a consistent feature of the genus. The genital double somite bears a transverse cuticular thickening which apparently supports the seminal receptacle. The importance of the integumental pore patterns of the urosome and legs as useful taxonomic characters is pointed out.

In the youngest stages observed the pistil is a single, apically open locule; the sept primordia on its wall are free from the pistil base. The septs grow towards the centre of the pistil. The concrescence of the septs is imperfect, resulting in open connections between the ovarial locules and towards the stigma.

Revision of Philippine Medinilla (Melastomataceae)
Provedor de dados: 16
Autores: Regalado Jr, Jacinto C.
The Philippine species of Medinilla (Melastomataceae) are revised and a total of eighty species are recognized for the Philippine archipelago, one of the centres of diversity of Medinilla. The species exhibit a wide array of forms and highly localized geographic distributions. A systematic study of herbarium specimens revealed the existence of twelve species groups. A key to the species groups and species within each group, descriptions, illustrations, and habitat information are provided. The segregate genera Carionia, Cephalomedinilla, and Hypenanthe are treated here as congeneric with Medinilla. One new species, M. palawanensis, is described. Three new combinations and several reductions, neotypifications, and lectotypifications are proposed.

Autores: Hay, A.; Hetterscheid, W.L.A.; Murata, J.; Boyce, P.C.; Bogner, J.; Jacobsen, N.
To complement the ‘Checklist of the Araceae of Malesia, Australia and the Tropical Western Pacific region’, a bibliography has been prepared as a basis for further work on the aroids of these areas. It is based on, but much extended from, an unpublished bibliography of Malesian Araceae assembled by the late Prof. Dr. C.G.G.J. van Steenis. It includes the ‘core’ taxonomic literature, i.e. that in which new nomenclature is introduced, and, in addition, numerous items appear which enumerate species, report expedition results, describe aspects of aroid biology, deal with nomenclatural matters etc. Flora accounts and extensive revisions of genera occurring in the region have been included for neighbouring areas. Those papers in which Araceae appear as but a...

Nonrandom variation in Poecilia marcellinoi n. sp. and P. salvatoris Regan, 1907 in El Salvador (Pisces, Poeciliidae)
Provedor de dados: 16
Autores: Poeser, Frederick N.
A new species of the genus Poecilia Bloch &amp; Schneider, 1801 is recorded from El Salvador. Morphological and meristic data of P. marcellinoi n. sp. and of the sympatric P. salvatoris Regan, 1907 are analysed. Intra- and interspecific variation are compared and correlated with environmental and interspecific influences. A high degree of character displacement is observed in populations from stable freshwater habitats. In habitats with presumed marine influences, this character displacement is counteracted by ecological stress. Based on the evidence presented, subspecific separation of observed ecotypes from literature is rejected.

The evolutionary significance of the Wajak skulls
Provedor de dados: 16
Autores: Storm, P.
Ever since their description by Dubois (1920, 1922) the Wajak skulls Java) have played an important role in the discussions on the evolution of modern humans in Australasia. Because of the robust morphology of the skull, Wajak Man was seen as a link between Pleistocene hominids from Java (Solo) and Recent Australian Aborigines. However, for a long time hardly any attention has been paid to the contents of the other boxes with human, faunal and cultural remains, as collected by Dubois around 1890. Because a satisfactory description of the Wajak fossils has so far been lacking and the archaeological context of the Wajak site has so far been ignored, the evolutionary position of Wajak Man necessarily remained unclear. The present study suggests that the...

A standardized description of European Sminthuridae (Collembola, Symphypleona), 3: description of seven species of Sminthurus, including four new to science
Provedor de dados: 16
Autores: Nayrolles, Pierre.
The following three species are redescribed: Sminthurus viridis (Linnaeus, 1758), Sminthurus nigromaculatus Tullberg, 1871, and Sminthurus multipunctatus Schäffer, 1896. Four new species are described from France and Spain: Sminthurus bourgeoisi n. sp., Sminthurus bozoulensis n. sp., Sminthurus leucomelanus n.sp.,and Sminthurus hispanicus n. sp. The importance of the ontogeny of chaetotaxy is stressed. Indeed, not all species acquire the secondary chaetotaxy in the same instar, and for these characters the most informative instar is not the adult but the third juvenile instar. The study of such characters involves the clustering of similar characters. A short discussion is given about this issue (selection of characters and clustering criteria).

A method is presented for the assessment of the botanical quality in the Netherlands. This quality is derived from the large national database FLORBASE which contains per square km, data on the presence of indigenous plant species in the period 1975-1990 (in all 4.5 million records). 7 Species were grouped into 28 ‘ecological groups’ according to the ‘ecotope classification’ system. 21 According to the fact whether a species is assigned to several ecological groups or a single one, it gets an indication-value ranging from 1/3 up to 1. From each square kilometer the indication-values are counted for each ecological group to form a score. Scores of different ecological groups are not mutually comparable because, for instance, each ecological group has its...

Two monocelid species with simplex copulatory bulbs and postpharyngeal ovaries have been found in E. Australia. One of them presents a combination of characters not found in any of the known genera of the Monocelididae, and the new genus Acanthopseudomonocelis is proposed for it. The new genus is characterized by the presence of four stylet-bearing accessory organs and by an internal vagina; it is related to Pseudomonocelis. The other species, Pseudomonocelis schockaerti n. sp., is characterized by a complex bursa-vagina system, and by a highly muscular penial organ and male antrum. It is closely related to P. pardii Schockaert &amp; Martens, 1987, from Somaliland. Two possibly additional species of the genus Pseudomonocelis, not found in a mature stage,...

Times change, and so does the first name of our venerable old journal. However, it is with reluctance that we change the first title of Bijdragen tot de Dierkunde into its former subtitle Contributions to Zoology. Nearly one hundred and fifty years ago, in 1848, the Royal Zoological Society “Natura Artis Magistra” in Amsterdam founded its periodical with a Dutch name, proud of the contributions zoologists in the Netherlands made to science. In the early years of its existence, the Bijdragen published articles either in Dutch or in French, with proportionately twice as many contributions in Dutch. Even German-born Hermann Schlegel (1804—1884) had his contributions to the Bijdragen published in either French or Dutch. It was not until 1884 that the first...

Systematic value of the ultrastructure of the sucker surface in the squid family Mastigoteuthidae (Mollusca: Cephalopoda)
Provedor de dados: 16
Autores: Salcedo-Vargas, Mario Alejandro.
The ultrastructure of the sucker surface is described and its systematic value for mastigoteuthid squids, which bear minute suckers, is considered. An introduction to sucker terms is given and a redefinition of these terms is attempted. Using scanning electron microscopic data, two genera and four subgenera of Mastigoteuthidae from the Northwest Pacific are distinguished. The presence of “cushions” in the sucker is discussed and considered as a character important for understanding adaptations of cephalopods to the deep-sea.

Morphology and evolution of Arytera pollen (Sapindaceae-Cupanieae)
Provedor de dados: 16
Autores: Bergen, M.A. van; Ham, R.W.J.M. van der; Turner, H.
A description of Arytera pollen based on light and scanning electron microscopic observations is presented. Four aperture types and two ornamentation types (one divided into two subtypes) can be distinguished. The commonest aperture types are colporate and parasyncolporate; each of the other two types occurs in a single species. The main ornamentation types are rugulate and striate-rugulate; the latter has small or large lumina. Polymorphism occurs in both characters in several species. A cladistic analysis of Arytera shows two distinct evolutionary trends in the pollen: 1) aperture system from parasyncolporate to colporate, and 2) ornamentation from striate-rugulate with small lumina to striate-rugulate with large lumina. The plesiomorphic state of the...

The main aim of the trip was to find an enigmatic aroid that was first collected as a sterile plant by the Australian plant enthusiast Dr. A. Dearden in 1990. The true identity of this Nephthytis-like plant, as we called it in the meantime, remained unclear and we thought that it was probably a new genus. It was collected in flower shortly (6 February 1994) before our trip by Dr. A. Hay of the Royal Botanic Gardens, Sydney. We also collected this aroid in the rain forest and in relictual regrowth near Bintulu. It grows as scattered individuals on the forest floor. Living plants brought back to Germany and England have grown very slowly, although one plant has flowered in the Botanischer Garten München. A thorough study of this aroid, including fruiting...

An annotated ornithological bibliography of Guinea-Bissau
Provedor de dados: 16
Autores: Hazevoet, C.J.
Guinea-Bissau, a former Portuguese colony, is a small country (36,125 km²) in West Africa bordered by Senegal in the north and Guinea (Conakry) in the east and south. Little is known about the country’s ornithology and comparatively few papers on its birds have been published. The following is an attempt at a comprehensive ornithological bibliography of Guinea-Bissau. Much of the results of ornithological work in the country have been published in Portuguese journals and Dutch reports, which are perhaps not easily traced otherwise. Some publications dealing with the avifauna of adjacent areas just across the borders with Senegal (e.g. Basse-Casamance) and Guinea (e.g. Ile Alcatraz, Iles Tristao) have been included when reference is made therein to...

The Asian species of Euaspis are reviewed. Euaspis carbonaria of authors is shown to be composite: a lectotype is designated and the species with which carbonaria has long been confused is described as Euaspis edentata spec. nov. Euaspis lorenzae spec. nov. is described from the Philippines and E. wegneri spec. nov. from Bacan (Moluccas). Two species described by Pasteels from 'Arabia' are shown to be of Bornean origin. Euaspis bakeri (Viereck, 1924) is synonymized with E. strandi Meyer, 1922, for which a lectotype is designated (the type locality Sikhim given by Meyer for this taxon is apparently false), and E. impressa (Viereck, 1924) with E. polynesia Vachal, 1903.

Autores: NN.
The spatial distribution of floristic activities and observations is mapped and analysed (Map 1, p. 162). The nature and importance of floristic data gathered by amateurs is compared with those of professional surveys. The use of the database FLORBASE is illustrated with various examples. Recently, the financial scope of FLORON has widened considerably. Besides, it now cooperates with several other non-governmental organizations of similar nature. Adding to this the enthusiasm of a large number highly motivated florists it may be concluded that floristics in the Netherlands faces a bright future. The Foundation FLORON was established in 1988. It coordinates and stimulates the activities of botanical naturalists observing the flora of The Netherlands (here...

Macrofauna associations and formation of shell concentrations in the Early Eocene Roda Formation (southern Pyrenees, Spain)
Provedor de dados: 16
Autores: Martinius, A.W.
The invertebrate macrofauna (mainly molluscs) of the Early Eocene Roda Formation (southern Pyrenees, Spain) is reported and classified in seven biofacies associations, representing ecologically related groups of macro-invertebrates of shallow marine fan-delta environments ranging in depth from intertidal mudflat to shallow carbonate shelf settings (maximum water depth c. 60 m). The most common association is indicative of mixed siliciclastic-carbonate substrates with the characteristics of an abandonment surface in shallow subtidal settings above wave base. The second most frequent biofacies association is found in subtidal normal marine outer-bay carbonate environments with a relatively low sedimentation rate. However, the most prominent associations,...

Provedor de dados: 16
Autores: Sanz, Sebastián; Platvoet, Dirk.
On several occasions, shrimps belonging to a new species of the genus Typhlatya were collected in a cave in the province of Castellón, Spain. This is the first record of the genus in the Iberian Peninsula. The species is described and the validity, distribution, and zoogeography of the genus, as well as the status of the genus Spelaeocaris, are discussed. Former models for the evolution of the genus Typhlatya and its genus group are reviewed, as well as the system of inner classification of the Atyidae and its biogeographical meaning. For the age and evolution of the genus we developed a new model based on vicariance principles that involves further evolution of each species after the disruption of the ancestral range. This allows new estimations for the...

Three species of the actinian genus Telmatactis Gravier, 1916, viz. T. forskalii (Ehrenberg, 1834), T. solidago (Duchassaing &amp; Michelotti, 1864) and T. cricoides (Duchassaing, 1850), occurring in Greece and the eastern Mediterranean, are described and discussed. Detailed data on the cnidom of the three species are provided. The characteristic penicilli of members of the genus Telmatactis are discussed. These penicilli were classified by Schmidt (1969, 1972) as p-rhabdoids (= penicilli) B1b, but it is here claimed that they actually belong in Schmidt's B2 group (provisionally as penicilli B2c). They correspond in general form and as to their distribution in the actinian polyp with the more usual penicilli B2a sensu Schmidt (1969), but unlike these, they...

Wat is biodiversiteit?
Provedor de dados: 16
Autores: Gittenberger, E.
Met de populaire term biodiversiteit wordt verwezen naar de enorme vormenrijkdom die het leven kenmerkt, van genen en eiwitmoleculen tot soorten van organismen en levensgemeenschappen. De huidige biodiversiteit is het resultaat van een zeer onregelmatig, principieel onvoorspelbaar evolutionair proces, gekarakteriseerd door tal van extreem asymmetrisch verlopende ontwikkelingen. Het toeval speelt bij de evolutie een belangrijkere rol dan regels en wetmatigheden.   Naast het ontstaan van nieuwe vormen, is ook het verdwijnen, uitsterven, door geleidelijke verandering of letterlijk, min of meer incidenteel of catastrofaal, steeds een wezenlijke factor geweest. Dit kan en mag evenwel geen argument zijn om het actuele, massale uitsterven onder menselijke invloed...

De samenstelling van de Nederlandse flora gerelateerd aan de kans op uitsterven (verdwijnen) van plantesoorten in de 20ste eeuw
Provedor de dados: 16
Autores: Meijden, R. van der; Gillis, J.E.M.
Tussen 1840 en 1990 zijn 73 plantesoorten uit Nederland verdwenen (tabel 3); daarnaast zijn in de laatste 25 jaar 14 soorten teruggevonden die als verdwenen werden beschouwd (tabel 4). Het aantal verdwijnende soorten is vanaf 1920 min of meer constant in de tijd: ca. 20 soorten per 20 jaar. Ook recent is er geen toename van het aantal verdwenen soorten geconstateerd, dit ondanks de toename van de bedreiging van veel biotooptypen. De studie toont aan dat er een zeer duidelijk verband bestaat tussen het areaaltype van de soort en de kans op verdwijnen. Soorten met een voorpost-areaal en met een marginaal areaal hebben een veel grotere kans te verdwijnen dan soorten met een centraal of subcentraal areaal; het verdwijnen van zulke soorten is een natuurlijk...

Binnen de districten Friesland-West en Friesland-Oost vormen de Waddeneilanden een apart verhaal. De bereikbaarheid en vervoerskosten vormen praktische obstakels om de eilanden ‘even’ te inventariseren. Bij ons kwam dan ook spoedig de gedachte op om eiland voor eiland aan te pakken. Vanaf 1990 werd per jaar één eiland geïnventariseerd, achtereenvolgens Ameland, Vlieland, Schiermonnikoog en Terschelling. Van de inventarisaties werd verslag gedaan in een rapport, dat telkens twee jaar na het veldwerk verscheen.¹²³ Terschelling, het grootste Friese Waddeneiland, is in 1993 op 10 kilometerhokken na geïnventariseerd. De inventarisatie van deze laatste hokken zal in de zomer van 1995 plaatsvinden. Uiteraard volgt daarna de rapportage. Hier richten we ons op de...

Biodiversiteit in Nederland

Autores: Nieukerken, E.J. van; Loon, A.J. van.
Biodiversiteit is een relatief nieuw begrip dat de rijkdom aan soorten en planten en dieren, maar ook van ecosystemen beschrijft. De toegenomen maatschappelijke zorg voor het verdwijnen van levensvormen heeft tijdens de Conferentie van Rio de Janeiro in 1992 geleid tot het Internationale Verdrag inzake de Biologische Diversiteit. Ook Nederland heeft als ondertekenaar van dit verdrag een bijzondere verantwoordelijkheid voor zijn eigen soorten planten en dieren. Hoeveel zijn dat er eigenlijk in Nederland? Wat doen overheid en particuliere natuurbescherming er aan om deze rijkdom in ons land te behouden? En wat is dat begrip biodiversiteit eigenlijk?    Dit boek probeert een antwoord te geven op een aantal van die vragen. Zo worden hier voor het eerst de...

Taxonomy and phylogeny of the Euphorbiaceae tribe Erismantheae G.L. Webster (Erismanthus, Moultonianthus, and Syndyophyllum)
Provedor de dados: 16
Autores: Welzen, Peter C. van.
The Erismantheae (monoecious, leaves opposite, stipules interpetiolar) contain three genera, Moultonianthus (monotypic), and Erismanthus and Syndyophyllum, each with 2 species. Moultonianthus is recognized by its persistent, large, cordate stipules; Erismanthus is characterized by the catkin-like staminate inflorescences with very long-pedicelled flowers; and characteristic for Syndyophyllum are the inflorescences with both staminate flowers (in bundles) and pistillate flowers (one per bundle of staminate flowers). Both varieties of Syndyophyllum occidentale are now considered to be distinctive species, because an additional difference was found (one axillary bud of each leaf pair present halfway along the petiole or not).

Two nesting grounds of the Moluccan Megapode, Eulipoa wallacei (G.R. Gray, 1860) located on the islands of Haruku and Halmahera, Indonesia, are described. Together they provide nesting opportunities for more than half of the estimated world population of this endangered megapode. Further information is given on six additional nesting grounds. Data are presented on size and origin of the megapode populations using these sites, egg-laying season, behaviour, and measurements of birds and eggs in relation to their breeding strategy of using solar heat for the incubation of their eggs.

The genus Crepidotus in Europe is considered. After an examination of 550 collections seventeen species and eight varieties are recognized. Two keys are supplied; all taxa accepted are typified. Morphological, ecological and chorological characters are critically evaluated. Descriptive statistics are used for basidiospore size. An infrageneric classification is proposed based on phenetic relationships using different cluster methods. The new combinations C. calolepis var. squamulosus and C. cesatii var. subsphaerosporus are introduced. The spore ornamentation as seen in the scanning electron microscope provides the best character for species delimitation and classification.

Each volume is projected to contain a hundred species, which means that eventually fifteen volumes will line up on our shelves. If the pace of production is not increased, most of us will be retired or dead by then. I really hope to live to see the completion of this series, because it is magnificent! It invites comparison with the legendary series ‘Venezuelan Orchids Illustrated’ by Dunsterville &amp; Garay, both in format and in the quality of the illustrations.

Presence of troglobitized Janiridae (Isopoda: Asellota: Janiroidea) in anchihaline caves of the Balearic Islands (Mediterranean); description of Trogloianiropsis lloberai n. gen., n. sp
Provedor de dados: 16
Autores: Jaume, Damià.
Trogloianiropsis lloberai n. gen., n. sp. is described from the flooded coastal karst of the Balearic Islands. It superficially resembles Ianiropsis Sars, 1897 and Janaira Moreira &amp; Pires, 1977, but differs from both in some remarkable characters. It seems to be restricted to the deeper layers of anchihaline cave lakes, and shows a troglobitized morphology (i.e.: absence of eyes and body pigmentation, and extraordinary elongation of antennae). Since its phyletic affinities are not clear, its biogeographic significance and possible derivation from deep-sea or shallow-water ancestors cannot be established.

On an average each species gets some eight pages of text, including a short general introduction, a fairly extensive description in which special attention is paid to wood, bark, rooting, flowers, fruits, and seeds; the seedling is often represented by a clear drawing; further are given notes on distribution, dispersal, ecology, culture, diseases, and uses. The text is illustrated with several often fine colour photographs depicting habit, bark, sometimes wood, leaves, flowers, fruits, and seeds, some drawings, and a map of the area of...

Naam- en codelijst van de Nederlandse macro-nachtvlinders (Lepidoptera: Heterocera)
Provedor de dados: 16
Autores: Vos, Rob de.
Vlinders zijn al geruime tijd één van de populairste insektengroepen bij natuurliefhebbers en -onderzoekers. Het gaat hierbij echter bijna uitsluitend om de grotere en veelal kleurrijke soorten, zoals dagvlinders en vertegenwoordigers uit enkele nachtvlinderfamilies als de beervlinders (Arctiidae), pijlstaarten (Sphingidae) en nachtpauwogen (Saturniidae). Andere nachtvlinders worden veelal beschouwd als sombere, grijze, lastig waar te nemen en vaak ondetermineerbare soorten. De uilen (Noctuidae) en spanners (Geometridae) vormen hierin de meest beruchte groepen. Sinds het uitkomen van de Catalogus der Nederlandse Macrolepidoptera van B.J. Lempke, waarvan de verschillende delen en supplementen tussen 1936 en 1970 verschenen, is de interesse voor de...

Provedor de dados: 16
Autores: NN.
Van de jaren 1992 en 1993 zijn inmiddels alle streeplijsten die voor 1 maart 1995 op het Landelijk Bureau zijn binnengekomen gedigitaliseerd. Ook hebben de eerste controlerondes op onjuiste of onvolledige kopgegevens plaatsgevonden, evenals de eerste fase van de controle op onwaarschijnlijke waarnemingen met het programma FORGET. Binnenkort zal ook de verdere controle van de als ‘onwaarschijnlijk’ gekwalificeerde vondsten plaatsvinden, waarbij u mogelijk door uw districtcoördinator benaderd wordt voor nadere informatie omtrent een waarneming. Als ook deze fase van de controle is afgerond beschikken we over een gecontroleerd bestand van FLORONwaarnemingen tot en met 1993. Het ligt in de bedoeling dit bestand op 1 oktober van dit jaar gereed te hebben. Voor...

Notes on Micractaeon, a monotypic genus of African land snails (Gastropoda Pulmonata: Ferussaciidae?)
Provedor de dados: 16
Autores: Bruggen, A.C. van; Winter, A.J. de.
Micractaeon kakamegaensis Verdcourt, 1993 (type loc. Kenya, Kakamega Forest), is a synonym of Pseudopeas koptawelilense Germain, 1934 (type loc. Kenya, Mt. Elgon); the proper name is therefore Micractaeon koptawelilensis (Germain, 1934). New anatomical data are supplied, more or less confirming classification in the family Ferussaciidae. The shell is subject to some considerable variation in size, shape and sculpture. The species appears to be widely distributed in various types of forest in tropical Africa (Ghana, Cameroon, eastern and south-eastern Zaïre, Kenya, Malawi, and eastern Zambia); hypsometrical distribution is generally from c. 950 m to c. 2300 m, although in Ghana it has been collected at altitudes of between &amp;lt; 250 and c. 700 m.

Natuurontwikkeling in het Rivierengebied
Provedor de dados: 16
Autores: Siebel, Henk.
Een opvallend verschijnsel in natuurontwikkelingsterreinen langs de grote rivieren is de aanwezigheid van uitgebreide ruigtekruidenvegetaties. Om kansen van andere soorten in de uiterwaarden aan te geven, is het zinvol na te gaan door welke factoren deze ruigte kan worden teruggedrongen. Rivieren hebben een sterk eutrofiërende werking op de uiterwaarden wat het ontstaan van ruigte bevordert. Terwijl andere verontreinigingen in het rivierwater afnemen blijft de nutriëntenbelasting hoog. Na afgraven van de voedselrijke toplaag zal er opnieuw voedselrijk slib in de zich hier ontwikkelende vegetatie worden ingevangen, zodat dit veelal slechts tijdelijk effect heeft. Minder voedselrijke situaties in de uiterwaarden komen met name op hoge delen van oeverwallen...

Phylogeny and biogeography of the Ergasilidae (Copepoda, Poecilostomatoida), with reconsideration of the taxonomic status of the Vaigamidae
Provedor de dados: 16
Autores: Pinto da Motta Amado, Maria Auxiliadora; Ho, Ju-Shey; Falavigna da Rocha, Carlos Eduardo.
Nineteen genera are currently considered valid in the Ergasilidae. A cladistic analysis was conducted on these genera and the five genera composing the closely allied Vaigamidae. Nineteen morphological characters were selected and polarized using Anthessius (Anthessiidae) as the outgroup. The most parsimonious cladogram (tree length = 60, Consistency Index = 0.50, Retention Index = 0.71), obtained through the use of the BB command in Hennig 86, is composed of eight major clades, with the five vaigamid genera composing the most derived clade. Based on Wiley’s (1981) “sequencing” convention, the five vaigamid genera cannot be placed in a family separate from the Ergasilidae. The biogeography of the ergasilid genera is discussed. Vaigamus spinicephalus is...

Autores: Koike, Masanori; Katsumata, Yukiyoshi; Amemiya, Yoshimiki; Shimada, Tohru.
To obtain alfalfa cell lines with high phenylalanine ammonia-lyase (PAL) activity in response to heat-released cell wall components (elicitor) of an alfalfa pathogen (Verticillium albo-atrum), in vitro selection was performed. The selection using a replica plating methods was carried out on 65 cell lines derived from suspension cultures treated and/or non-treated with N-metyl-N'-nitro-N-nitrosoguanidine (MNNG) of the susceptible genotype of cv. Vertus. Three stable high PAL cell lines in response to elicitor (two cell lines recovered from MNNG treatment, one from non-MNNG treatment) were isolated. All these cell lines showed higher PAL activities, lignin depositions and phytoalexin accumulations than the parental cell line after treatment with active V....

This study was conducted to determine the effect of storage on the properties of potato starch. Starch was prepared from three varieties of potato, namely; Benimaru, Toyoshiro and Konafubuki, after storage at 5°C for 6 months. The average granule size, phosphorus content, Brabender peak viscosity and breakdown of the starches from the stored tubers for each variety were lower than those from the unstored tubers. The initial pasting temperature did not have a considerable change. The temperature at peak viscosity of Benimaru starch increased, while it decreased for both Toyoshiro and Konafubuki starches after storage. The viscosity and rigidity of 1% starch pastes also decreased during storage while the blue value increased. The decrease in Brabender peak...

Autores: Mailu, G.M.; Kiai, S.P.M.
Kenya has a growing population projected to increase to 34 million people by the turn of the century. Though the country is undergoing industrial transformation, agriculture remains the mainstay of the economy. The country has an area of about 587 900 km2 of which 576 000 km2 is land surface. 88% of the land surface is classified as arid and semi-arid lands (ASALs) and the remaining 12% forms the medium and high agricultural potential land. This classification is based mainly on the moisture index as indicated by average annual rainfall and evapotranspiration. The Great Rift Valley running north/south influences and determines the drainage pattern so that from the flanks of the Rift Valley, water flows westwards to Lake Victoria and eastwards to the Indian...

During april 1995 hydrochemical research in a vertical column on the east side of the Galápagos Islands (Cruise T95/04/01) onboard of the INP R/V Tohallí indicated that concentrations of ammonium, nitrate, phosphate and chlorophyll-a were found stratified from the surface to deeper layers, on the other hand the maximum levels of nitrite and silicate were detected 70 m below the thermocline. The apparent oxygen use (AOU) varied from 1 to over 3 below the thermocline, this would indicate an oxidating environment due to the high levels of nitrate, phosphate, silicate and low concentrations of dissolved Oxygen (ca. 90-134[µM]) and ammonium (&lt;0,1[µM]).

The past intersessional period has been marked by a very significant change in the fields of networking, and electronic publication of data and information. The Internet and the World Wide Web (WWW) have attracted major attention and have become the way to do business for a broad community of data and information users who did not previously have the means to do such exchanges, either locally or globally. Since IODE-XIV in October 1992, a large number of IODE data and information centres have begun to use the Internet and have established various types of servers to display and deliver data, information, and services. The rate of advancement of technology is something that has to be noted and taken into account by IODE. If one thinks back to October 1992,...

Autores: Kimani, E.N.
Coral reefs are a prominent feature of the East African coastline and associated islands. The Kenya-Tanzania coastline stretches from 1°30'S, at the Somali border to approximately 10°S at the Mozambique border. The Seychelle Islands extend from 5°S to 10°S and 45°E to 56°E (Fig. 1). The climate along the East African coast is dominated by seasonal monsoon winds (northeast monsoon from No-vember to February and southeast monsoon from March to October) and the equatorial currents dictated by the intertropical convergence zone. The narrow East African continental shelf supports fringing and patch reefs which lie 0.5 to 2 km offshore. General profiles of East African coasts are given in Table 1. Gaps in the reefs occur near river mouths notably Tana, Athi and...

Sebkha is a North African vernacular name for a shallow, salty depression. It is a common wetland type especially in semi-arid and arid climates but less so in sub-humid climates. In Tunisia, about 80 wetlands of this type stretch from north to south, most of them located within a short distance of the coast although not usually connected to the sea. They play a major hydrological role in stocking flood waters, recharging and/or discharging groundwater and are prime habitats for a diverse and typical fauna and flora thus generating many benefits to local communities and society as a whole.

Seychelles krab ziraf (Ranina ranina) fishery: the status of the stock
Provedor de dados: 20
Autores: Boulle, D.P.
The local commonly used kreol name for Ranina ranina is krab ziraf.  The krab ziraf fishery in Seychelles started functioning as a commercial fishery in 1986 when the resource was identified as potentially viable.  Prior to this time these crab stocks were unexploited.  In keeping with the Seychelles Fishing Authority (SFA) policy of monitoring catch and effort in new fisheries a research programme was implemented to assess the state of the Seychelles stock and determine the viability of the fishery as a whole. The objective of this report is to provide an indication of the state of the crab stock at the present fishing levels and give estimates of the standing stock biomass and the potential yield of the fishery. The biomass estimates give a range of...

This report reviews the spiny lobster fishery on the Mahe Plateau during the 1994 - 1995 fishing season. Following the recommendations made after the 1992 fishing season, the fishery was reopened in 1993 for two months, November and December.  The monitoring programme set up in 1992 was continued to gather more information on the spiny lobster stocks so as to improve the management of this resource around the Mahe Plateau. A total of 33 licenses were issued (compared to 28 in 1993); 25 on Mahe, 2 on Praslin and 6 on La Digue.  A licensed fishing unit comprised, on average, of three men. Snorkelling was used by 27 fishing units as the only catching method, 3 fishing units used traps only whilst 3 fishing units combined snorkelling with the use of traps....

Coastal Ecosystems
Provedor de dados: 20
The coastal forest communities of Kenya exist mainly as isolated blocks which show high levels of species endemism and comprise a total of about 83,800ha in a narrow belt which extends inland for about 30km. The forests are characterized by dense or moderately dense stands of tall trees, species of the genera Sterculia, Chlorophora and Memecylon. The drier woodlands include stands of Cynometra, Manilkara and Afzelia. Centuries of human occupation have reduced the forest element which was originally more extensive. Mangrove swamps occur in tidal estuaries and lagoons while coconut palms are common above high tide. A complex of many bush types occur in the high bush area. Scattered baobab trees present a striking appearance while the prevalence of mango...

Benthic communities and geomorphology of the Tesoro Island Coral Reef, Colombian Caribbean
Provedor de dados: 20
Autores: Sánchez-M., Juan M.
The benthic communities distribution in Tesoro Island (Colombian Caribbean) coral reef was determinad by cartography of reef morphology and functional groups from aerial photographs, theodolite triangulation, and bottom transects over depths ranging from O to 30 m. Tesoro Island is a sand cay reef developed over an emerged reef platform whose basal cone possibly originated by mud diapirism on the continental shelf. The benthic communities are distributed as subzones of the geomorphologic units. The reef crest lies along the breaker zone, formed by Millepora spp. buttresses covered on their tops by Palythoa spp. and seawardly by a turf of Dictyota spp. The rear reef (varying from 0.5-1.5 m ¡n depth) is composed of pavement and grooves with live Porites...

Autores: Cuadra, T. de la.
More than one hundred oceanographic stations were occupied between the Galápagos Archipiélago and the Ecuadorian coast during April-May 1995. All the information were treated statically using the method of ”Kriging” to interpolate; from this, surface distribution of sea temperature, sea temperature anomalies, air temperature, and atmospheric presion were obtained. These distributions with temperature and salinity profiles showed the end of the warm period 1994-1995. Upwelling events were detected and were supposed to about 24% of AESS. From the mass water analysis carried out to the east San Cristóbal. It was found a probable relationship between the AESS and the ASTS, and the pelagic fisheries.

Mytilopsis sallei es una especie que se encuentra ampliamente distribuida sobre sustratos duros en la Ciénaga Grande de Santa Marta, siendo particularmente abundante sobre bancos de ostra de mangle (Crassostrea rhizophorae), donde alcanza densidades de hasta 5000 indiv/m2. Aunque posee una amplia tolerancia a variaciones en la salinidad y temperatura, prefiere aquellos lugares donde la afluencia de aguas dulces es constante. Puede además tolerar aguas turbias con un alto contenido de sedimentos, como en la desembocadura de los ríos. M. sallei no parece aparentemente, competir con la ostra, incluso en aquellos bancos sometidos a intensa explotación. Esto se debe a las preferencias ambientales de cada especie y a la alta productividad de las aguas de la...

Data-Recording System and Sampling Strategy in the Western Indian Ocean Purse-Seine Fishery
Provedor de dados: 20
Autores: Thomas, A.; Dufour, O.; Pianet, R.; Morón, J.
The present data-recording system used in the Seychelles to compile the tuna purse-seine statistics in the WIO was established by ORSTOM at the beginning of the fishery (1982/3) for the French fleet, and then extended to the Seychelles Fishing Authority (SFA) and Madagascar in 1991-92 for all fleets. After several modifications, it has been working efficiently for the last ten years, making it possible to build a very comprehensive tuna database for the purse-seine fleets since the beginning of the fishery. The extension to Madagascar started in 1992, within the framework of the Regional Tuna Project. A specific laboratory, the(Unité Statistique Thonière d’Antsiranana (USTA) was installed, the work being done in collaboration between ORSTOM, the Direction...

The two most important foreign exchange earning activities in the Seychelles are tourism and fisheries and therefore, the coastal areas and their management are of the greatest importance to the Seychelles government (Khadun, 1991). In recent years government policy has encouraged marine conservation (Procter, 1970; 1984-1989 National Development Plan) and is part way to fulfilling the programme outlined in the Environmental Management Plan of the Seychelles (EMPS, 1990-2000). To date, five marine areas have been designated as national marine parks covering about 23 000 ha with several more proposed parks and protected areas. However, financial constraints, a deficit of qualified personnel, lack of boundary delimitation, inadequate legislation and...

Review of Fisheries Biology of Scomberomorus and Acanthocybium Species in the Western Indian Ocean (FAO Area 51)
Provedor de dados: 20
Autores: Siddeek, M. S. M.
The seerfish group (Scomberomorus and Acanthocybium species) contributes less than 2% to the total landings from the western Indian Ocean (FAO Area 51, Fig. 1) (FAO 1994). Although its contribution is minor in quantity when compared with the landings of other major fish groups, it is considered as the prime fish in almost all the countries bordering this area. Seerfish fetch a higher price per kilogram than any other marine fin-fish landed in these countries. It is also a valuable export product in some of these countries (e.g., Oman). The high demand appears to have triggered over-exploitation of some stocks living in this region. Therefore, research studies are needed to assess these stocks to formulate appropriate management and development plans....

Macrobrachium vollenhovenii and Macrobrachion, the two largest Macrobrachium species in Nigeria waters attain maximum adult sizes of 19cm and 13.5cm respectively. Male - female ration is approximately 1.1 for both species. Male dimorphism has been observed in M. macrobrachion but not in M. vollenhovenii.  Both prawns breed throughout the year (usually in the brackish waters) with peaks in the rainy season. Although berried females of M. vollenhovenii occur in landlocked water bodies, rearing the larvae has so far been successful in brackish water.  Bi-weekly spawning peaks occur in M. macrobrachion but are still to be verified for M. vollenhovenii.

During the year under review, attention was focussed on the survey of white shrimp fishery and its mechanisation status in Nigeria.  Survey results indicate that at sea, the crayfish beam trawl fishery is all year round, but rough from July to September.  Catches are therefore better from October and best between December and June.  However, where rains are heavy and early, stow net shrimp fishery at sea is best from January to March.  Within the year a series of violent Swells/sourges devastate the Victoria Island beach in Lagos.  The preliminary survey of the Institute showed that nourished beach is slightly above the level of  the Ahmadu Bellow way.

Autores: Manongi, E.J.
The Rufiji River basin has wetlands with economic functions that require conservation; these functions have hitherto been taken for granted. Mismanagement of this basin wouldhave direct effects on these various functions and their values. The execution of largeprojects (e.g. hydropower and irrigation) may have effects which need to be evaluated.Coordinated planning and management at the river basin level is required for the sustainableutilisation of wetlands. To illustrate river basin planning, the catchment of the Rufiji River has been used as anexample in this paper. The Rufiji Basin (Figure 1) is the largest catchment basin in Tanzania, covering 177,420 km2, and has the highest potential for hydropower in Tanzania.

Tagging is considered an excellent tool for estimating the importance of interactions and competition between fisheries as well as to study tuna stocks and migrations. The Regional Tuna Project of the Indian Ocean Commission (IOC) conducted five tagging cruises in the western Indian Ocean, during which 955 fishes were tagged. Out of the total number tagged 15 were recaptured. Tuna tagging in the Indian Ocean was also undertaken by the Indo- Pacific Tuna Programme and by the Japanese National Research Institute of Far Seas Fisheries. 39 tuna marked by these organisations were recovered in Mauritius. Analysis of data collected from the tag recoveries provide some preliminary estimates of growth rate and migration of tuna. Tagging is the most direct method to...

This dissertation is focused on the study of implications of spatial patterns on survival of eggs and larvae and subsequent recruitment of the SW Atlantic anchovy, Engraulis anchoita. The study of distribution patterns is encompassed within the conceptual framework of the analysis of reproductive strategies of marine bony fish, as adaptations that enable them to cope with and actively exploit environmental variability, regulating their abundance and avoiding extinction. The SW Atlantic anchovy, is ideally suitable for studies on reproductive biology and recruitment on a comparative basis. Its spawning and nursery grounds are located in very diverse ecosystems. This variety refers to their physico-chemical properties, carrying capacity, the influence of...

Data used to generate the tables and figures presented here are based on daily catch and effort report forms (1ogs') returned from the fishing vessels which are licensed to fish in the Seychelles EEZ. Sometimes there is a delay in these being received at SFA, especially after the second quarter of the year when most vessels are fishing in the Mozambique Channel. Readers should be aware that many of the figures presented here are subject to revision (usually upwards) as more data become available. The date upon which the SFA database was closed prior to the generation of the statistical tables is now shown at the head of each table.

Autores: Rossi, G.; Blivi, A.B.
Situé sur la frontière Togo-Bénin, le Mono draine un bassin-versant d'environ 30000 km2 et se jette dans l'Atlantique par l'intermédiaire d'un vaste système lagunaire. Un premier barrage, celui de Nangbeto, a été construit en 1987, modifiant de façon drastique le régime hydro-sédimentaire naturel dans la vallée et à l'embouchure. Un second barrage, celui d' Adjarala, va être entrepris....

Succesional patterns on fouling plates in the Bay of Santa Marta, Colombian Caribbean
Provedor de dados: 20
Autores: García, C.B.; Salzwedel, H.
Successional progress was followed ¡n fouling communities, developing under tropical conditions. Primary succession was simulated by immersing asbestos plates. The plates represent small, discrete, isolated parts of habitat. According with expectations, a trend of increasing space dominancy by colonial forms was detected as succession progressed. High within-habitat diversity but global persistency was confirmed f or this tropical system. Several mechanisms of succession were found to operate simultaneously. In this Caribbean fouling system the strong self-replacement tendencies of solitary forms and the low recruitment and growth rates of the potential space dominants (colonial forms) were mostly responsible for the successional patterns observed.

Coralline Algae, Important Coral-reef Builders Threatened by Pollution
Provedor de dados: 20
Autores: Mohammed, S.M.; Björk, M.; Björklund, M.; Semesi, A.
The release of inorganic nutrients into the sea by domestic sewage is a major threat to many marine systems. This eutrophication affects coral-reef organisms indirectly by increased growth of microalgae, leading to increased sedimentation, decreased light availibility, rapid growth of opportunistic macroalgae, etc. In this paper, we report a decrease in the cover of important group of coral-reef builders, the coralline algae. This decrease might be caused by the outlets of sewage water from Zanzibar town. Laboratory and field experiments show that both the growth rate and the calcification of these organisms are negatively affected by high phosphate levels, but not by nitrate or ammonia.

The effect of replacing fish meal (tuna waste with graded levels of toad meal in diet for Clarias gariepinus fingerlings (Bruchell 1822)
Provedor de dados: 20
Autores: Bekibele, D.O.; Ayinla, O.A.; Saidu, A.A.
A feeding trial was conducted on the replacement of fish meal (Tuna waste) with oven dried toad meal in diets for Clarias gariepinus fingerlings average weight 3.6g in concrete tanks for 56 days.  Average weight gain, % weight gain, specific growth rate, apparent digestibility coefficient, protein efficiency ratio and feed conversion ratio showed no significant difference as the level of toad meal increased. The only recorded mortalities occurred in the control and treatment of (25% replacement level) at 16.67% and 8.33% respectively and may have been due to handling stress.  Toadmeal compares favourably with fish meal (tuna waste) and could be conveniently used in its replacement.

Provedor de dados: 20
Autores: Rueda, Mario E.; Mancera-Pineda, José E.
Con el propósito de evaluar los impactos generados por el uso de un método de pesca artesanal denominado "boliche" en la laguna costera tropical Ciénaga Grande de Santa Marta, se cuantificaron diferentes aspectos; uno de los cuales fue orientado a analizar algunas alteraciones físico-químicas de la columna de agua, producidas durante la maniobra de pesca. Se determinó la concentración de oxígeno disuelto, la transparencia del agua y la concentración y composición del seston, antes y después de 70 lances de boliche. Los resultados indican que la maniobra de pesca genera algunos cambios momentáneos de poca repercusión en el ecosistema, tales como resuspensión de partículas principalmente inorgánicas, aumento de la concentración de seston y en consecuencia...

Ctenochaetus marginatus (Valenciennes) (Pisces: Acanthuridae) en la Isla de Gorgona: Primer registro del género para el Pacífico colombiano
Provedor de dados: 20
Autores: Zapata, F.A.; Morales, Y.A.
The genus Ctenochaetus is reportad in the waters of the Colombian Pacific based on two specimens of C. marginatus (Valenciennes) collected in 1993 at Gorgona Island (2°59' N, 78° 12' W). These specimens differ inseveral morphometric characteristics from thosepreviously examined. Such differences appear to be an artifact of the small number of specimens formerly examined and the consequent narrow ranges reportad. We suggest that temperature variability affects the distribution of C. marginatus in the tropical eastern Pacific.

IOC Workshop on Ocean Colour Data Requirements and Utilization, Sidney, Canada 21-22 September 1995.
Provedor de dados: 20
Ocean colour data is essential for monitoring and fostering our understanding of important ocean biological processes. Adequate data pertaining to ocean biological processes is extremely difficult to obtain due to the vast area of the ocean (over 70 % of the earth’s area) and to the logistical difficulties of shipboard sampling. Satellite views of ocean colour are our only chance for gaining an overall view of the state of ocean biology at any given time. Ocean colour data is also the most practical way to develop the time-series data that will allow us to separate natural variability in ocean biological processes from secular changes. Ocean colour data will allow us to monitor at a minimum such important areas as: biogeochemical cycles, direct effects of...

Nematode assemblages of deep-sea and shelf break sites in the North Atlantic and Mediterranean Sea
Provedor de dados: 27
Autores: Soetaert, K.; Heip, C.H.R.
The nematode community structure of several shelf break and deep-sea stations in the North Atlantic and the Mediterranean is compared using data from the literature. Samples from 2 Mediterranean deep-sea canyons have a unique fauna of predatory and scavenging nematodes (e.g. &lt;i&gt;Synonchiella, Halichoanolaimus, Gammanema&lt;/i&gt;) which comprise some 20 to 30% of the community, while some of the typical deep-sea genera (&lt;i&gt;Theristus, Acantholaimus&lt;/i&gt;) are only marginally present. The nematode generic composition of the other sites reveals a gentle transition from the shelf break (Bay of Biscay; Mediterranean) over the slope (Mediterranean) towards the continental rise, abyssal plain and hadal depths (Bay of Biscay, Puerto Rico Trench,...

Wind wave modelling in shallow water: with application to the southern North Sea
Provedor de dados: 27
Autores: Luo, W.
Increased marine activities, particularly in areas of off-shore exploitation and coastal development, have created an urgent need for improved knowledge of wave conditions in the shallow near-shore regions. In this work, objectives have been made to investigate the effects of bottom friction, depth-induced wave breaking, and tidal motions on the wave evolution in shallow water, and to apply the wave model (WAM Cycle 4) to the Belgian coastal waters. Firstly, the effects of different bottom friction formulations on the energy balance equation were quantitatively investigated for fetch-limited shallow water conditions. It was found that the formulation of the bottom friction dissipation has a quite significant effect on the energy balance at shallower water...

Comparative study of the hyperbenthos of three European estuaries
Provedor de dados: 27
Autores: Mees, J.; Fockedey, N.; Hamerlynck, O.
The hyperbenthic fauna of the subtidal channels of the Eems (N. Netherlands), Westerschelde (S.W. Netherlands), and Gironde (S.W. France) estuaries was sampled within a 15-day period in summer 1991. In each estuary, quantitative samples were taken at regularly spaced stations covering the entire salinity gradient from marine conditions at the mouth to nearly freshwater conditions upstream. The diversity of the samples and the distribution of the species along the main estuarine gradients were assessed. Hyperbenthic communities were identified using different multivariate statistical techniques. The species composition and the density and biomass of the dominant species of each community were compared among communities.

Correct taxonomic identification of &lt;i&gt;Artemia&lt;/i&gt; species

Autores: Sorgeloos, P.; Beardmore, J.A.
In order to prevent any further confusion in the scientific literature, we would like to urge contributors to ensure that the citation of &lt;i&gt;Artemia&lt;/i&gt; in scientific articles in &lt;i&gt;Aquaculture Research&lt;/i&gt; is taxonomically correct. Too frequently, reference is made to &lt;i&gt;Artemia salina&lt;/i&gt;. This binomial refers to a European species which may be extinct. Most scientific studies are, however, based on the New World species &lt;i&gt;Artemia franciscana&lt;/i&gt;. We estimate that over 90% of the studies in which &lt;i&gt;Artemia&lt;/i&gt; is used as experimental test organism or as food source deal with this particular species, very often using material from the Great Salt Lake in Utah, USA. Today at least six bisexual...

Eocene sediment supply in western Belgium as determined through heavy mineral distribution
Provedor de dados: 27
Autores: Jacobs, P.
The distribution of heavy minerals in Middle to Upper Eocene deposits of western Belgium is discussed with reference to ternary diagrams based on density (&lt;3.4; 3.4-4.2; &gt;4.2) and mineralogical composition (ubiquist, parametamorphic and garnet-epidote-amphibole-pyroxene groups). A corresponding diamond diagram is used to interpret the transport mode and the energy of the sedimentary environment.The Aalter Formation (middle Eocene), which was deposited in a quiet to turbulent setting, contains high amounts of ubiquists, parametamorphic minerals and garnets, with a minor epidote and amphibole content. The Maldegem Formation (middle to late Eocene) of deltaic origin, is characterized by the dominance of ubiquists, particularly in the sands and silts....

Sequential determination of a combined gamma/ß and pure ß-emitter by gamma and liquid scintillation counting: application to the transport of metals across fish gills
Provedor de dados: 27
Autores: Van Ginneken, L.; Blust, R.
A combined gamma scintillation/liquid scintillation technique for the sequential determination of two radioactive tracers is described. The method was developed using a combined gamma/ß-emitter (&lt;sup&gt;57&lt;/sup&gt;Co) and a pure ß-emitter (&lt;sup&gt;45&lt;/sup&gt;Ca). First, the &lt;sup&gt;57&lt;/sup&gt;Co radioactivity was determined by counting the samples in a gamma scintillation analyzer in the energy region 80-165 keV. Next, the samples were counted in a liquid scintillation analyzer. Only one energy region was used to count both isotopes to maximize the counting efficiencies. From the difference between quenched and unquenched ß-spectra, the counting region was set from 0 to 256 keV. The counting efficiency was related to a quench-indicating...

Autores: Merchie, G.; Lavens, P.; Dhert, Ph.; Dehasque, M.; Nelis, H.; De Leenheer, A.P.; Sorgeloos, P.
Ascorbic acid (AA) is an essential nutrient in particle and live aquafeeds. In order to better assess the needs for this nutrient during larviculture the AA content of algae, rotifers and &lt;i&gt;Artemia&lt;/i&gt; was studied with respect to their suitability at startfeeding. In general, the microalgae evaluated were rich in AA (1000-4000 µgAA/gDW), but showed a considerable variability among the different species: e.g. the concentration in &lt;i&gt;Isochrysis&lt;/i&gt; and&lt;i&gt;Chlorella&lt;/i&gt; reached values 3-to 4-fold the percentage of &lt;i&gt;Tetraselmis&lt;/i&gt; (0.11% of DW). &lt;i&gt;Brachionus&lt;/i&gt; routinely cultured on &lt;i&gt;Chlorella&lt;/i&gt; contained 2300 µg AA/gDW.

In order to assess the dietary needs for ascorbic acid (AA) at startfeeding, the AA content in the various live diets currently applied in aquaculture (algae, rotifers, &lt;i&gt;Artemia&lt;/i&gt; ) was studied. Application of boosting techniques using ascorbyl palmitate (AP) as the vitamin C source enabled the transfer of elevated levels of bioactive vitamin C (up to 2500µg AA.g DW&lt;sup&gt;-1&lt;/sup&gt;) via the live food chain into larvae of fish (&lt;i&gt;Clarias gariepinus, Dicentrarchus labrax, Scophthalmus maximus&lt;/i&gt;), shrimp (&lt;i&gt;Pennaeus vannamei&lt;/i&gt;) and prawn (&lt;i&gt;Macrobrachium rosenbergii&lt;/i&gt;).

Bedforms on the Middelkerke Bank, southern North Sea
Provedor de dados: 27
Autores: Lanckneus, J.; De Moor, G.
Large dunes cover the flanks and summit of the Middelkerke Bank. They have constant orientation heights ranging from 0.5 to 5 m, wavelengths of 75 to 150 m and in most cases asymmetrical profiles. No relationships could be established between the heights of the large dunes and the grain sizes of the sediment or the water depth in which they are developed. The slopes of both lee and stoss flanks are very low. Almost every large dune on the bank can assume both ebb and flood orientations through time. Two cases are presented in which particular swell and wind conditions induced common orientations to nearly all the large dunes. No significant migration was observed for six large dunes on the northern end of the bank over a time span of 13 moths during which...

Autores: Romdhane, M.S.; Devresse, B.; Léger, Ph.; Sorgeloos, P.
Larvae of the freshwater prawn (&lt;i&gt;Macrobrachium rosenbergii&lt;/i&gt;) were reared to post-larvae in a closed recirculation system. Six treatments were designed where freshly-hatched &lt;i&gt;Artemia&lt;/i&gt; nauplii were first given to the larvae for 3, 7, 11, 15, 17 and 25 days according to the treatment. After that (omega-3) HUFA-enriched &lt;i&gt;Artemia&lt;/i&gt; were given until the 28th day at which time the test was terminated and evaluated. The requirement for (omega-3) Highly Unsaturated Fatty Acids (HUFA) for the larval stages of &lt;i&gt;M. rosenbergii&lt;/i&gt; was confirmed by this experiment.

This paper discusses the structure of fish assemblages using information from 17 European estuarine areas (in the British Isles, Portugal, Belgium, France, the Netherlands, Germany, Norway and Spain). Binary (presence/absence) and quantitative data for each assemblage have been used to assess the assemblage structure according to taxonomy (&lt;em class="a-plus-plus"&gt;i.e.&lt;/em&gt; species identity). Following this, a total of 29 functional guilds were created in order to describe the use made of an estuarine area for each taxon encountered: feeding preferences, reproduction type, substratum preferences (for bottom dwelling fish) and position within the water column (vertical preference guild). The paper focuses on the designation and determination of...

Improvements in the larviculture of turbot &lt;i&gt;Scophthalmus maximus&lt;/i&gt;: zootechnical and nutritional aspects, possibility for disease control
Provedor de dados: 27
Autores: Dhert, Ph.; Lavens, P.; Dehasque, M.; Sorgeloos, P.
The rotifer feeding regime for larval turbot could be improved by more regular feeding and adjusted food distributions as to prevent overfeeding and digestion problems. All tests were successfully run in clear-water conditions indicating that the administration of algae is not essential during the rotifer stage. Larval requirements with respect to (n-3) RUFA, and more specifically DRA and DRA/EPA ratio appeared to change according to the age of the larvae and the physiological condition at the different larval stages. As early as the first week the stress resistance of the larvae could be improved by feeding rotifers specifically enriched in DRA. However, the continuous feeding of these live preys did not result in the best larval output, indicating that...

The metazoan meiofauna of nine stations in shelf break and upper slope areas (70 to 1500 m water depth) of the N.E. Atlantic were investigated in order to assess which environmental factors are important in the control of densities and sediment profiles. Total meiofaunal densities (ranging between 368 and 1523 ind/10 cm&lt;sup&gt;2&lt;/sup&gt; were correlated with bacterial densities, an important food source for meiofauna. However, considering sediment vertical distribution profiles, the relative importance of both food and oxygen on the meiofauna became obvious. A combination of both bacterial densities and oxygen supply could explain about 95% of the variability in the vertical profiles of the meiofauna densities. Meiofauna numbers increase in...

Meiobenthic distribution and nematode community structure in five European estuaries
Provedor de dados: 27
Autores: Soetaert, K.; Vincx, M.; Wittoeck, J.; Tulkens, M.
Meiofauna from the intertidal zone of five European estuaries (Ems, Westerschelde, Somme, Gironde, Tagus) was investigated. Samples represented a cross section of various benthic habitats from near-freshwater to marine, from pure silts to fine-sandy bottoms. The meiobenthic community comprised everywhere a fauna strongly dominated by nematodes, with meiobenthic density increasing with increasing salinity. The Ems differed from the other estuaries due to the presence of a well developed community of Copepods, Gastrotrichs, large Ciliates and/or soft-shelled Foraminiferans in some sites. The Westerschelde stood out due to the near-absence of harpacticoid copepods and, as in the Tagus, the lower meiobenthic densities in the marine part of the estuary. For...

Live food enrichment techniques, using formulated diets and emulsions for improving the nutritional quality of &lt;i&gt;Brachionus&lt;/i&gt; and &lt;i&gt;Artemia&lt;/i&gt; , were studied as a tool for transferring ascorbic acid (AA) to fish larvae. &lt;i&gt;Artemia&lt;/i&gt; nauplii enriched for 24h with an experimental emulsion containing 20% HUFA and 0%, 10% and 20% ascorbyl palmitate (AP) were administered to catfish larvae in a 20-day feeding trial. Survival was not affected by the dietary AA, but from day 7 onwards a significantly positive effect of supplemental AA on growth was demonstrated. At the end of the experiment the 20% AP group weighed 30% more than the control (0% AP), i.e. 9.5 and 6.3mg DW, respectively. Evaluation of the physiological...

The potential impact of meiofauna on the recruitment of macrobenthos in a subtidal coastal benthic community of the Ligurian Sea (north-western Mediterranean): a field result
Provedor de dados: 27
Autores: Danovaro, R.; Fraschetti, S.; Belgrano, A.; Vincx, M.; Curini-Galletti, M.C.; Albertelli, G.; Fabiano, M.
The composition and dynamics of meio- and macrofauna in a subtidal location at Zoagli (Ligurian Sea, Italy) were followed for an annual cycle (from January 1991 to January 1992). Polychaete recruitment occurred during spring and late summerautumn. The increase in density of predatory nematodes (dominated by &lt;i&gt;Oncholaimellus, Viscosia, Mesacanthion &lt;/i&gt;and &lt;i&gt;Chromaspirina&lt;/i&gt;) and turbellarians corresponded to the collapse of macrobenthos recruits. Such alteration was probably due to predation by turbellarians and predator-nematodes during and immediately after the macrofaunal larval settlement. Differences in predator pressure were observed between spring and autumn. Conversely, no significant impact was observed on bivalves. The...

Production and consumption of biological particles in temperate tidal estuaries
Provedor de dados: 27
Autores: Heip, C.H.R.; Goosen, N.K.; Herman, P.M.J.; Kromkamp, J.; Middelburg, J.J.; Soetaert, K.
The question is reviewed whether a balance exists between production and consumption of biological particles in temperate tidal estuaries and what the relationships are between the magnitude of production and consumption processes and system carbon metabolism. The production terms considered are primary production by phytoplankton, microphytobenthos, macroalgae and vascular plants and the chemoautotrophic production, mainly by nitrifying bacteria. The consumption terms are generalized by considering pelagic and benthic mineralization, but major consumer compartments, heterotrophic bacteria, zooplankton, meiobenthos, and macrobenthos are considered in detail. The proposition that estuaries are heterotrophic systems, and become more so when nutrient inputs...

Aberrant individuals of &lt;i&gt;Neomysis integer&lt;/i&gt; and other Mysidacea: intersexuality and variable telson morphology
Provedor de dados: 27
Autores: Mees, J.; Fockedey, N.; Dewicke, A.; Janssen, C.R.; Sorbe, J.-C.
Intersexuality in the mysid &lt;i&gt;Neomysis integer&lt;/i&gt; is described from samples collected in the Elbe (north Germany), Eems-Dollard (north Netherlands), Westerschelde (south-west Netherlands) and Gironde (south-west France) estuaries. Individuals which had an irregularly shaped or nearly symmetrically rounded telson, rather than a typically truncated one, were also recorded from the four populations studied. A culture experiment with damaged specimens revealed that all types of abnormal telson morphology found in the field can result from regeneration of damaged parts. It is concluded that both intersexuality and aberrant telson morphology are widespread phenomena among estuarine &lt;i&gt;N. integer&lt;/i&gt; populations. Both abnormalities seem...

Nematode community structure along a Mediterranean shelf-slope gradient
Provedor de dados: 27
Autores: Soetaert, K.; Vincx, M.; Heip, C.H.R.
Nematode assemblages along a Mediterranean depth transect (160-1220 m) and vertically in the sediment were investigated. The station at the edge of the continental shelf (160 m) was distinctly different from those situated on the continental slope (280-1220 m). On the slope, nematode communities in the upper centimetre differed significantly from communities in the deeper sediment layers, which were dominated by fewer and larger species. Vertical segregation could be a factor explaining the coexistence of several species belonging to the genus &lt;i&gt;Sabatieria&lt;/i&gt;, with larger species penetrating deeper into the sediment. Clear differences in buccal morphology suggest food resource partitioning as the dominant factor promoting coexistence of...

Autores: Tackx, M.; Irigoien, X.; Daro, N.; Castel, J.; Zhu, L.; Zhang, X.; Nijs, J.
As in most European estuaries, the mesoplankton of the Westerschelde and the Gironde is dominated by calanoid copepods. In the Westerschelde, &lt;i&gt;Eurytemora affinis&lt;/i&gt; dominates the brackish water area between station 7 and 10 in winter and spring while &lt;i&gt;Acartia tonsa&lt;/i&gt; is dominant in summer. Maximum abundance of &lt;i&gt;A. tonsa&lt;/i&gt; is located slightly more seawards than that of &lt;i&gt;E. affinis&lt;/i&gt;. &lt;i&gt;Acartia bifilosa&lt;/i&gt; occurs in winter and spring in lower abundances than &lt;i&gt;A. tonsa&lt;/i&gt; and its maximum abundance is located between the brackish and the marine area.

Copepod production in the southern Benguela system
Provedor de dados: 27
Autores: Hutchings, L.; Verheye, H.M.; Mitchell-Innes, B.A.; Peterson, W.T.; Huggett, J.A.; Painting, S.J.
Several methods have been used to indirectly estimate copepod production in the southern Benguela region, based on field sampling of copepod stages and laboratory measurements of growth and development rates under variable food and temperature regimes. Estimates of production have steadily increased from 11 gC m&lt;sup&gt;-2&lt;/sup&gt; y&lt;sup&gt;-1&lt;/sup&gt; in 1979 to 80 gC m&lt;sup&gt;-2&lt;/sup&gt; y&lt;sup&gt;-1&lt;/sup&gt; in 1987. Since 1988, extensive measurements of copepod egg production and moulting rates of &lt;em&gt;Calanus agulhensis&lt;/em&gt; at sea during hydro-acoustic fisheries surveys over the south and west coasts of South Africa in November have provided more direct estimates of copepod production.

Atmospheric concentrations and deposition of heavy metals over the North Sea: a literature review
Provedor de dados: 27
Autores: Injuk, J.; Van Grieken, R.
A literature review of the atmospheric concentration rates and dry and wet deposition fluxes of particulate Cd, Cr, Cu, Pb and Zn to the North Sea and adjacent areas is given. The results of direct measurements of dry and wet deposition fluxes are compared to indirect estimates and to modelling values. This work points out the large uncertainties in results of different studies on atmospheric input of trace elements into the North Sea. The current knowledge about the dependence of the deposition velocity upon the particular size and about the processes controlling wet deposition fluxes, and the quality and completeness of the emission data are still adequate for describing the environmental cycle and impact of heavy metals in the North Sea.

The leading role of ammonium in the nitrogen uptake regime of Southern Ocean marginal ice zones
Provedor de dados: 27
Autores: Goeyens, L.; Dehairs, F.A.; Tréguer, P.; Bauman, E.M.; Baeyens, W.F.J.
The nitrogen signature of marginal ice zones in the Southern Ocean often departs from the "classical" Antarctic nutrient profiles with high nitrate and low ammonium values in the surface layer. Weddell Sea marginal ice zones e.g. show enhanced nitrate depletions, amounting to similar to 500 mmol N m super(-2). Additionally, ammonium stocks in the upper layer can be up to 7% of the inorganic nitrogen pool. The corresponding nitrogen uptake regime suggests elevated nitrate assimilation during the early phase of the productive season and significantly reduced nitrate assimilation at a later stage. Absolute as well as specific nitrate uptake rates decrease by an order of magnitude when ammonium stocks exceed 1.7% of the total inorganic nitrogen. The...

Nitrogen dynamics in the Westerschelde estuary (SW Netherlands) estimated by means of the ecosystem model MOSES
Provedor de dados: 27
Autores: Soetaert, K.; Herman, P.M.J.
A tentative nitrogen budget for the Westerschelde (SW Netherlands) is constructed by means of a simulation model with thirteen spatial compartments. Biochemical and chemical processes in the water column are dynamically modeled; fluxes of dissolved constituents across the water-bottom interface are expressed by means of diagenetic equations. The model is calibrated on a large amount of observed variables in the estuary (1980-1986) with relatively fine temporal and spatial detail. Additional constraints are imposed by the stoichiometric coupling of carbon, nitrogen and oxygen flows and the required conservation of mass. The model is able to reproduce rather well the observed distributions of nitrate, ammonium, oxygen and Kjeldahl nitrogen both in time and...

The metazoan meiofauna in the region off Kapp Norvegia, Antarctica (Weddell Sea: 71°S, 12°W), was collected from depths between 211 and 2080m. Total meiofaunal abundance ranged from 815 to 5122 ind. per 10 cm² and total biomass from 126 to 966 µg dwt per 10 cm². Nematodes dominated the samples (range 83 to 97%) followed by harpacticoid copepods, polychaetes and kinorhynchs. A typical skewed length frequency distribution was obtained with most nematodes in the 0.4 to 0.6 mm size-class. The meiofauna communities were primarily influenced by bathymetric depth and food availability (e.g. organic matter and microbiota), which in turn are suggested to be directly related to phytoplankton blooms and associated sedimentation pulses.

Holocene evolution of relative sea level and local mean high water spring tides in Belgium: a first assessment
Provedor de dados: 27
Autores: Denys, L.; Baeteman, C.
Holocene age-depth data from the Belgian coastal plain, basal peat data particularly, are assessed in terms of local water and tide levels. Basal peat formation was generally induced by sea-level rise; effects of local seepage were limited and significant river-gradient effects were absent. No relation was found between the timing of basal peat inception and substrate permeability. In general, edaphic (moisture) conditions were unfavourable for organic accumulation prior to sea-level related rise of the groundwater table. Error envelopes for the minimum level of local mean high water spring tides and for upper and extreme lower relative mean sea-level limits during the last 9400 solar years (8400 yrs B.P.) are presented. These indicate that the rate of...

Autores: Sorgeloos, P.; Dehasque, M.; Dhert, Ph.; Lavens, P.
Dependable availability of quality fry to stock grow-out production systems has been one of the most critical factors in the commercial success of industrial production of fish and shellfish. Large-scale production of marine fish fry was realized only from the 1980s onwards. Although Japan was the pioneer with the red sea bream (&lt;i&gt;Pagrus major&lt;/i&gt;), the most competitive hatchery methods were eventually developed in Europe for the sea bass (&lt;i&gt;Dicentrarchus labrax&lt;/i&gt;) and the gilthead sea bream (&lt;i&gt;Sparus aurata&lt;/i&gt;). Improved knowledge of larval dietary requirements, not the least with regard to (n-3) highly unsaturated fatty acids (HUFAs), combined with the adoption of live-food enrichment protocols allowed the...

The &lt;i&gt;Pomatoschistus minutus&lt;/i&gt; (Pallas) and &lt;i&gt;P. lozanoi&lt;/i&gt; (de Buen) stock of the ebb-tidal delta of the former Grevelingen estuary was sampled monthly from September 1992 to October 1993. Sagittae were extracted and the areas of the sagitta and sulcus acusticus were measured with a digitizer. The frequency response and auditory threshold of these two sympatric goby species were determined from the ratio of the sulcus acusticus area to the sagitta area (S:O ratio). The S:O ratio of &lt;i&gt;P. minutus&lt;/i&gt; increased while in &lt;i&gt;P. lozanoi&lt;/i&gt; the S:O ratio was constant with increasing standard length. The average S:O ratio of &lt;i&gt;P. lozanoi&lt;/i&gt; was significantly higher than that of &lt;i&gt;P....

Autores: Peleteiro, J.B.; Lavens, P.; Rodríguez-Ojeja, G.; Iglesias, J.
The paper presents the data relating to the spawning quality of 20 turbot females (&lt;i&gt;Scophthalmus maximus&lt;/i&gt;L.) subjected to natural and controlled photoperiods and fed with two different types of food. A comparison is made between the data usually utilized in hatcheries for defining the spawning quality (number of viable eggs, fertilization and hatching rates, number of larvae produced) and the highly unsaturated fatty acid (HUFA) content of fertilized eggs at the two-cell stage. The results indicate that there is no correlation between the HUFA content of the eggs and any of the egg quality criteria examined. Nevertheless, significant differences (p&lt;0,05) are found between the females fed with fresh trash fish (higher 18:3n-3, 20:4n-6,...

A standard experimental diet for the study of fatty acid requirements of weaning and first ongrowing stages of European sea bass (&lt;i&gt;Dicentrarchus labrax&lt;/i&gt; L.): selection of the basal diet
Provedor de dados: 27
Autores: Coutteau, P.; Van Stappen, G.; Sorgeloos, P.
A standard experimental diet was developed to study lipid nutrition in marine fish larvae during weaning and first ongrowing. Basal diets were prepared by extrusion-cooking, crumbling of the pellets, and sieving to obtain particles in the size ranges 150-300 µm and 300-500 µm. Three protein sources in the extruded basal diet were evaluated: (1) micronized cod protein granulate (COD); (2) a mixture of casein, gelatin, and albumin (CGA); (3) a mixture of cod fish meal, whey protein, soybean protein concentrate, albumin, hemoglobin meal, and wheat gluten (MIX). A variable lipid fraction was added to the extruded nucleus by coating the particles with an emulsion, coconut oil (COCO), or fish oil emulsion (FO), in a fluidized bed granulator. European sea bass...

Live feeds in aquaculture
Provedor de dados: 27
Autores: Dhert, Ph.; Sorgeloos, P.
Over the past two decades intensive larviculture of several fish and shellfish species has expanded into a multimillion dollar industry. Although much progress has been made in identifying the dietary requirements of the larvae of various aquaculture species, the mass culture of their early larval stages still requires the use of live feeds. Selected either through trial and error approaches or because of their convenience in mass production and use, hatcheries are relying today on three groups of live feed, i.e. various species of microscopic algae, the rotifer &lt;i&gt;Brachionus&lt;/i&gt; and the anostracan brine shrimp &lt;i&gt;Artemia&lt;/i&gt; .Various species of microalgae are used in feeding mollusc and shrimp larvae and/or in greenwater fish...

Provedor de dados: 27
Autores: Schrijvers, J.; Okondo, J.; Steyaert, M.; Vincx, M.
A cage experiment was used to exclude the epibenthos from the &lt;i&gt;Ceriops tagal&lt;/i&gt; mangrove sediment at Gazi Bay, Kenya. This made it possible to study interactions with the meiobenthos (in terms of predation, food competition and food enhancement). The density of the meiobenthic taxa and nematode genera and a broad range of abiotic variables were followed in a depth profile over 1 yr of caging. There was a significant exclusion effect in the upper sediment layer for total meiofauna, nematodes and oligochaetes during the first 2 mo and for copepods during the last 6 mo of caging. The density of the most common predatory and microalgae-feeding nematodes in particular tended to increase in the surface layers as well as the percentage of muddy...

Measuring selectivity of feeding by estuarine copepods using image analysis combined with microscopic and Coulter counting
Provedor de dados: 27
Autores: Tackx, M.L.M.; Zhu, L.; De Coster, W.; Billones, R.G.; Daro, M.H.
Although estuarine zooplankters are generally believed to be detritivorous, high clearance rates by the estuarine copepods &lt;i&gt;Eurytemora affinis&lt;/i&gt; and &lt;i&gt;Acartia tonsa&lt;/i&gt; on natural estuarine microplankton have been reported in the literature. In order to enable detection of possible selectivity for these microplankton organisms over detritus, a method that measures clearance rates on total particulate matter is proposed. Image analysis is used to measure copepod gut contents, and combined with Coulter counter measurements of total particulate matter concentration, allows one to calculate clearance rates on the latter. The first results indicate that, in the Westerschelde estuary (SW Netherlands), both &lt;i&gt;E....

Estimating estuarine residence times in the Westerschelde (The Netherlands) using a box model with fixed dispersion coefficients
Provedor de dados: 27
Autores: Soetaert, K.; Herman, P.M.J.
The residence time of the water masses in the Westerschelde estuary was determined using a simple compartment-model that simulates the advective-diffusive transport of a conservative dissolved substance (chlorinity). The residence time of a water parcel in the upstream part of the estuary (i.e. the time needed for this water parcel to leave the estuary) varied from about 50 days in winter to about 70 days in summer. The most seaward compartment had residence times of about 10-15 days. Dispersive coefficients that are fixed in time were able to reproduce the observed salinity distributions very well in the Westerschelde. They were obtained by calibration on observed chlorinities. It is argued that the apparent relationship of dispersive coefficients with...

Effect of dietary phosphatidylcholine on growth and lipid composition of post-larval &lt;i&gt;Penaeus vannamei&lt;/i&gt; (Boone)
Provedor de dados: 27
Autores: Camara, M.R.; Coutteau, P.; Sorgeloos, P.
Dietary phospholipids and particularly phosphatidylcholine have been found to enhance growth and survival in penaeid shrimp, an effect which has been attributed to their limited ability to synthesize phospholipids de novo. However, most of the studies made so far have used low purity phospholipids and therefore, precise requirements for dietary phosphatidylcholine among several species of shrimp have been difficult to establish.As part of a broad study which aims to study lipid nutrition in penaeid shrimp, the dietary effect of purified phosphatidylcholine (PC) on growth, survival, stress resistance and body lipid composition of post-larval &lt;i&gt;Penaeus vannamei&lt;/i&gt; fed semi-purified microbound diets was evaluated.

With the advent of intensive culture practices, occurrences of mass mortality caused by bacterial infections are commonplace. High doses of antibiotics or antibacterials are used in aquaculture by adding them to the water. Problems of palatability and leaching occur when the chemotherapeutic agents are incorporated in feeds. To circumvent these problems &lt;i&gt;Artemia&lt;/i&gt; can be used as a carrier. In this study we assess the efficacy of cotrimoxazole in the oral treatment of turbot larvae challenged with a pathogenic strain of Vibrio anguillarum encapsulated in &lt;i&gt;Artemia&lt;/i&gt;.

Abundance and biomass sizes spectra of nematodes have been investigated at two contrasting abyssal sites in the NE Atlantic. The northern site is situated on the Porcupine Abyssal Plain where there is evidence for a high seasonal input of organic matter derived from the overlying water column. The southern site is the oligotrophic station of the French EUMELI programme off Mauritania and is characterized by low primary productivity in the overlying water column and consequently by a lower organic input to the deep-sea floor.

Larval ontogeny in fish is characterized by important anatomical and physiological phases with consequent changes in nutrient requirements. Depending on the size of the larva and the specialization of its digestive system at the initiation of exogenous feeding, live food remains an essential requirement for many marine and some freshwater fish species. This paper reviews the latest developments in the selection, production and/or use of the most commonly used live feeds in larviculture, i.e. micro-algae, rotifers, and brine shrimp.Species-specific dietary requirements are met by application of live food enrichment techniques with selected nutrients. It is very likely that broodstock nutrition and conditioning might influence the nutritional requirements of...

Nauplii of the brine shrimp &lt;i&gt;Artemia franciscana&lt;/i&gt; were enriched with the antibacterial drug sarafloxacin hydrochloride to determine if levels effective against four pathogenetic strains of &lt;i&gt;Vibrio&lt;/i&gt; spp. would accumulate in brine shrimp. Three vibrio strains were &lt;i&gt;Vibrio anguillarum&lt;/i&gt;; the fourth was &lt;i&gt;V. vulnificus&lt;/i&gt;. Concentrations of sarafloxacin ranging from 1 to 40% (weight: volume) were incorporated into the oil phase of Super Selco brine shrimp diets. Enriched nauplii and controls were sampled at 2h interval for 24h. Antibiotic sensitivity testing was evaluated with a modification of the Kirby-Bauer disk diffusion method.

Improvement of grain-size analyses using the automated SEDIGRAPH 5100
Provedor de dados: 27
Autores: Wartel, S.; Barusseau, J.-P.; Cornand, L.
The method of analysing fine grained sediments is discussed and an improved technique using a water-glycerol solution of known density instead of water is proposed. Inaccuracies resulting from wet sieving may contribute to explain the observed difference between the pipette method and the Sedigraph 5100 analyses.

Kalium-Natrium-Verhältnis in Demeter-Möhren
Provedor de dados: 21
Autores: Hagel, I.
Einleitung:   Biologisch-dynamisch angebaute Möhren (Markenzeichen demeter) werden teilweise zur Saftherstellung verwendet. Einige Verarbeiter garantieren im Möhrensaft bestimmte Mindest- und Höchstwerte für die Mineralstoffe Kalium (K) und Natrium (Na). Wie berichtet wurde, erfüllten einige Partien der angemeldeten Möhren diese Voraussetzung nicht in gewünschtem Maße. In diesen Fällen ist das Qualitätsziel des Verarbeiters und somit auch der Verkauf der Möhren an diesen gefährdet. Aus diesem Grund wurde im Jahre 1993/94 ein Projekt durchgeführt um einen besseren Überblick über die Mineralstoffgehalte von Möhren aus biologisch-dynamischem Anbau zu bekommen.    41 Möhrenproben und 36 Bodenproben der Ernte 1993 wurden untersucht. Zusätzlich wurde ein...

Nachwachsende Energieträger im Organischen Landbau
Provedor de dados: 21
Für den Vergleich der Entwicklungspfade sind die CO2-Minderungspotentiale einer Erzeugung nachwachsender Energieträger auf stillgelegten Flächen, unter Beibehaltung jetziger intensiver Formen der Landwirtschaft, der CO2-Minderung einer flächendeckenden Organischen Landbewirtschaftung gegenüber zu stellen (vgl. HAAS et al. 1995). Der Organische Landbau selbst wird aufgrund systemimmanenter Erfordernisse keinen relevanten Beitrag bei der Erzeugung nachwachsender Energieträger mit den heute in der Diskussion befindlichen Hauptnutzungs-Kulturen erbringen können. Für die Verwendung von Reststoffen können einzelbetriebliche oder lokale Standortvoraussetzungen Substitutionspotentiale für fossile Energie in geringerem Umfang bereitstellen. Der zu hohe fossile...

Earthworm populations in conventional/organic arable-based systems and their contribution to soil fertility OF0117T
Provedor de dados: 21
Autores: Scullion, John.
The project aimed to characterise earthworm population dynamics and behaviour under rotational cropping, comparing organic and conventional systems. Benefits arising from earthworm activity in terms of soil fertility were also assessed. Although some difficulties were encountered with details of the work, these problems did not affect the overall reliability of research findings and the broad aims were achieved.    Earthworm populations, casting and burrowing, and selected soil or cast properties (microbial biomass, available P and K, organic content and aggregate stability) were monitored on three pairs of matched organic-conventional farms over a two year period. Farm pairs represented a gradation from stockless to ley-arable systems. The survey was...

Ein Lagerversuch mit Möhren aus biologisch-dynamischem Anbau

Autores: Hagel, I.
Einleitung:   Alle Substanzen der Möhre werden nur durch das ihnen übergeordnete Prinzip des Lebens so gestaltet und bewahrt, dass sie eben als das erscheinen, was wir dann als knackige Möhre mit bestimmtem Geruch und Farbe wahrnehmen können. Ist diese innere Kraft der Möhre innewohnende Kraft aber unzureichend, so entgleiten die Stoffe dem Gesamtverband, und die Möhre verfault. In diesem Moment werden die Mineralstoffe tatsächlich wieder zu dem, was sie ohne die Eingliederung in das Leben sind, nämlich tote Substanzen. Der Mensch, der eine Möhre - oder eine andere Frucht - verzehrt, braucht aber nicht nur die toten Mineralstoffe, sonst könnte er auch prächtig gedeihen mit diesen in Tablettenform. Das tut er nicht. Er braucht zusätzlich die Möglichkeit,...

A whole-farm case study on 32 Norwegian farms, out of which most were dairy farms, showed that animal health was better on organic farms than the Norwegian average. This is probably due to dominantly spring calving, much lower rations of concentrate and lower milk yields. Roughage yields were ca 10% lower than on conventional farms in the same district.

Klimarelevanz des Agrarsektors der Bundesrepublik Deutschland: Reduzierung der Emission von Kohlendioxid
Provedor de dados: 21
Autores: Haas, Guido; Geier, Uwe; Schulz, Dirk; Köpke, Ulrich.
Der Agrarsektor (Landwirtschaft, Garten- und Weinbau) der Bundesrepublik Deutschland (alt) verbrauchte im Jahre 1990/91 Energie in Höhe von ca. 413,82 PJ, entsprechend einem Anteil von näherungsweise 3,6% des nationalen Gesamtenergie-Einsatzes. Die daraus abgeleitete Kohlendioxid-Emission lag bei insgesamt ca. 27,658 Mio t CO2 und damit näherungsweise bei einem Anteil von insgesamt 3,9% der nationalen Emission. Flächenbezogen verursachte der Agrarsektor eine Kohlendioxid-Emission in Höhe von 2,344 t CO2 je Hektar.      Die von der Bundesregierung Deutschlands angestrebte CO2-Minderung von mittelfristig 25 - 30% kann auch innerhalb des Agrarsektors umgesetzt werden.

O aumento da concentração de adubo apresentou os efeitos esperados. Comprovou-se uma alterção significativa das propriedades aqui estudadas através do uso de preparado biodinâmico, aplicado separadamente ou combinado em forma de preparado composto ou irrigado. Não fica claro porém em quais circustâncias ele atua e porque em certos casos a sua influência é contraditória. No projeto aqui apresentado encontram-se ainda em processo de análise outros parâmetros destes dois últimos anos de colheita, como concentração de nutrientes ( por exemplo ácido ascórbico, nitrato, minerais). Espera-se que após a análise do conjunto de variáveis dos cinco anos de plantio previstos seja possível estabelecer parâmetros para o aprimoramento da qualidade da batata proveniente...

Die gesteigerte Düngung ergab an beiden Standorten bei den meisten Parametern die erwarteten Effekte. Eine Wirkung der biologisch-dynamischen Präparate, entweder getrennt in Kompost- und Spritzpräparate, oder kombiniert angewendet, konnte ebenfalls bei mehreren Parametern nachgewiesen werden. Allerdings ist nach wie vor nicht klar, unter welchen Umständen diese Präparate wirken und warum sie z.T. gegensinnige Effekte haben. In dem hier vorgestellten Projekt stehen zur Zeit aus den letzten beiden Versuchsjahren noch diverse Parameter, u.a. einige Inhaltsstoffe (z.B.

Gegenüber der anthropogenen CO2 Freisetzung, die im nichtlandwirtschaftlichen Be¬reich durch Nutzung fossiler Brennstoffe und bezogen auf die Weltlandwirtschaft durch Landnutzungsänderung verursacht werden, sind die Rückbindungsmöglichkeiten der Landwirtschaft gegenüber der globalen Freisetzung gering. Die pflanzliche Senke für CO2 ist umso größer, je höher der produzierte Gesamtertrag, je geringer der zur Synthese der Inhaltsstoffe dissimilierte CO2 Anteil und je höher die Dauer des Erhaltes der synthetisierten organischen Substanz als Erntegut und dem Boden zugeführte Erntereste ist.

Autores: Elliot, Mr J; Keatinge, Mr R; Powell, Mr L; Unwin, Mr R.
1.  The aim of this study was to assess the economics and constraints associated with home finishing lambs on a range of organic hill and upland farms in England and Wales, and to evaluate the potential for further finishing on registered farms in the lowlands.    2.  The current state of the organic sheep sector is briefly reviewed.  This identifies problems of scale, limited premia and uneveness of supply as limiting factors to more rapid development of the market and associated production systems.    3.  To quanitfy the effect of organic management on financial performance, hill and upland farms were classified under four typical systems, depending on the degree of intensification.    4.  Without a sizeable area of improved ground, to which fertiliser...

Key Conclusions  1.  The crop rotations of organic systems maintain landscape diversity and biodiversity whilst the maintenance of field boundaries on organic units produces benefits to a wide range of organisms.  2.  Inorganic nitrogen fertilisation and herbicide treatments of conventionally managed grassland has reduced the floral diversity of permanent pastures and maintained the low diversity of re-seeded pastures, greatly reducing their value as wildlife habitats.  3.  Pesticide use is responsible for the removal of food sourcesfor birds and mammals in the form of weeds and invertebrates, as well as removing whole populations of potentially beneficial insects.  4.  The majority of water pollution incidents from farms are caused during storage and...

Nitrogen Turnover on Organic and Conventional Mixed Farms
Provedor de dados: 21
Autores: Halberg, Niels; Kristensen, Erik Steen; Kristensen, Ib Sillebak.
Separate focus on crop fertilization or feeding practices inadequately describes nitrogen (N) loss from mixed dairy farms because of (1) interaction between animal and crop production and between the production system and the manager, and (2) uncertainties of herd N production and crop N utilization. Therefore a systems approach was used to study N turnover and N efficiency on 16 conventional and 14 organic private Danish farms with mixed animal (dairy) and crop production. There were significant differences in N surplus at the farm level (242 kg. N/ha. vs. 124 kg. N/ha. on conventional and organic dairy farms respectively) with a correlation between stocking rate and N surplus. N efficiency was calculated as the output of N in animal products divided by...

Comportamiento de la poblacion de Avena fatua tratada con graminicidas postemergentes
Provedor de dados: 87
Autores: Juan,V.F.; Irigoyen,J.H.; Orioli,G.A.
En el sudoeste bonaerense de la República Argentina, avena fatua es una maleza que ocupa una significativa proporción del banco de semillas presentes en el suelo, causando severas pérdidas de rendimiento en los cultivos de trigo, lo cuál la caracteriza como una maleza invasora. A pesar de que en los cultivos, se utilizan normalmente prácticas de control com graminicidas selectivos, se observa una alta incidencia de la población de Avena fatua a través de la determinación del número de panojas y semillas por metro cuadrado remanentes de las plantas que escapan al control y que alcanzan el estado reproductivo antes de la cosecha del cereal. El objetivo de este estudio fue evaluar el efecto de varios graminicidas postemergentes selectivos para el cultivo de...

Autores: Mascarenhas,Maria Helena T.; Galli,Antônio João B.; Viana,Maria Celuta M.; Macêdo,Geraldo A. R.; Lara,José Francisco R.
A flora daninha infestante de um canavial é bastante específica e bem característica. O uso contínuo do mesmo herbicida é um dos fatores relacionados ao manejo, que mais tem contribuído para essa seleção. A tiririca (Cyperus rotundus) aparece como uma das principais espécies daninhas infestantes dos canaviais. O objetivo do presente trabalho foi avaliar a eficiência do controle químico da tiririca, através da utilização do herbicida halosulfuron, pertencente ao grupo químico das sulfoniluréias, na cultura da cana-de-açúcar. O experimento foi instalado na EPAMIG, em Prudente de Morais - MG, em 24 de março de 1994, com a variedade RB-72454, em solo de várzea Glei Pouco Úmido, textura argilo-siltosa com pH 5,8 e 2,9% de matéria orgânica.

Controle de plantas daninhas em feijão num sistema de rotação culturas em plantio direto
Provedor de dados: 87
Autores: Rodrigues,Benedito N.; Passini,Telma.
O objetivo deste trabalho foi selecionar culturas de inverno para formação de cobertura morta que reduza a população de plantas daninhas na cultura do feijão (Phaseolus vulgaris). Ocupou-se o terreno durante o ano todo, com a sucessão, em plantio direto, de pousio ou cultura de inverno/feijão/cultura para silagem, estudando-se três modalidades de controle de plantas daninhas na cultura do feijão. A maior renda líquida acumulada após duas safras foi obtida com feijão semeado sobre palha de aveia-preta e controle de plantas daninhas com um gramicida pré-emergente, completando-se com capinas, quando necessário.

Banco de sementes e estabelecimento de plantas daninhas em agroecossistemas
Provedor de dados: 87
Autores: Carmona,Ricardo.
Em novembro/92 o banco de sementes no solo foi estimado, a 0-10 cm de profundidade, em alguns agroecossistemas: área de rotação de culturas, várzea, pomar de cítrus e pastagem de Brachiaria brizantha, no Distrito Federal, Brasil. Esta estimativa foi realizada através da observação da emergência de plântulas em amostras de solo incubadas, com e sem lavagem através de peneira e presença ou ausência de nitrato de potássio. A lavagem do solo para redução de volume, seguida de utilização de nitrato de potássio, mostrou-se desvantajosa para a determinação dos bancos de sementes viáveis detectadas nas amostras. A quantidade média de sementes por metro quadrado foi de 22313 na várzea, 6768 na área de rotação, 3595 nas coroas do pomar e 529 na pastagem....

AN EMPIRICAL INVESTIGATION OF IMPORTANCE RATINGS OF MEAT ATTRIBUTES BY LOUISIANA AND TEXAS CONSUMERS
Provedor de dados: 31
Autores: Hui,   Jianguo; McLean-Meyinsse,   Patricia E.; Jones,   Dewitt.
This study provides an empirical investigation of how consumers rate meat attributes. Results show an importance order for 12 selected meat attributes and reveal some relationships between the importance ratings and consumer's demographic or socioeconomic characteristics. The findings suggest that (1) the meat marketing strategy should focus on freshness, taste, and appearance; (2) nutritional attributes have become important factors in the meat purchasing decision of female, educated, and married consumers; (3) older, married, low-income, or non-white consumers still remain price conscious; and (4) USDA label has become an important symbol of meat quality and safety to older, female, Baptist, and high-income consumers.

Overview of Rural Income Taxation: Issues, Implications and Importance
Provedor de dados: 31
Autores: Wood,   Richard.
The main purpose of this paper is to discuss aspects of taxation policy as it is applied to rural sector issues. The paper begins by reviewing the relevance of rural income volatility, and general trends in protection policy, for taxation policy design. Comments are included on the general appropriateness of concessional tax treatment and a description is provided of key taxation policy principles - equity, efficiency, certainty and administrability. The paper then illustrates how these taxation policy principles are taken into account during the policy advising process. Four case studies are used for this purpose: drought, water reform, horticulture and landcare.

PHYTOSANITARY REGULATION AND AGRICULTURAL FLOWS: TOBACCO INPUTS AND CIGARETTES OUTPUTS
Provedor de dados: 31
Autores: Overton,   Benny; Beghin,   John C.; Foster,   William E.
This paper examines the effects of the use of increasingly-popular phytosanitary regulations on production costs, and output and factor trade flows.  The case addressed is that of the European regulation of maximum chemical residues in cigarettes manufactured with tobacco containing maleic hydrazide.  The paper presents simulations of the effects of tightening the input/output market linkages and on the substitution away from the residue-contaminated U.S. input to residue-free non-U.S. inputs.  This induced substitution results in higher costs, lower quantity supplied of the final product, and higher prices for U.S. cigarettes in Europe.  Cross-price effects lead to higher quantities of EU cigarettes sold and a corresponding increase in the use of all...

Autores: Kennedy,   Gary A.; Henning,   Steven A.; Vandeveer,   Lonnie R.
This report presents the results from the first annual Louisiana Rural Land Market Survey. The survey was designed to collect detailed information from rural real estate professionals regarding market conditions in their areas. Results of this study suggest that land values vary by area of the state and the primary commodity grown on the tract. Substantial variation in land value within areas and by parish suggests a number of factors affect rural land values and markets. Further research will be designed to measure the effects of these various factors on rural real estate markets.

A Case for Re-evaluation of Income Averaging for Primary Producers
Provedor de dados: 31
Autores: Douglas,   Robert A.; Davenport,   Scott V.
Income averaging for primary producers is a long-standing tax policy in Australia. Major changes were made to the scheme in 1983 to overcome anomalies associated with the previous scheme. However the amended scheme has not been subject to review.  In this review, the scheme is found to perform poorly against the traditional evaluation criteria of equity, efficiency and simplicity. The general conclusion is that to avoid cross-subsidisation and investment distortions which are often inherent features of any general scheme, it is appropriate to consider the adequacy of self-averaging mechanisms.

AN EVALUATION OF POST CONSERVATION RESERVE PROGRAM ALTERNATIVES IN THE TEXAS HIGH PLAINS
Provedor de dados: 31
Autores: Johnson,   Phillip N.; Segarra,   Eduardo.
Four policy alternatives for CRP lands upon expiration of the current contracts in Hale county, Texas are evaluated using chance-constrained programming. It was found that if CRP contracts are extended at the current average rental rate, 40 percent of the current enrollment would be expected to return to crop production, while 66 percent would return to crop production if the program were eliminated. The results also indicate that the marginal value of CRP payments to producers is lower than the marginal value of deficiency payments.

Agro-Exports and the Rural Resource Poor in Latin America: Policy Options for Achieving Broadly Based Growth
Provedor de dados: 31
Autores: Carter,   Michael R.; Barham,   Bradford L.; Mesbah,   Dina; Stanley,   Denise.
Concentrating on fundamental sector-level impacts that shape the nature of agro-export growth, this paper indicates how intrahousehold impacts fit into the analysis. Section 1 is introductory. Section 2 puts forward the conceptual framework needed to understand sectoral impacts of agro-export growth on the rural resource poor, impacts that can be divided into a small-farm adoption effect, a land-access effect, and a labor-absorption effect, all of which are interlinked. Section 3 explores the economic forces that shape the magnitude of the direct (adoption and land access) and indirect (labor absorption) effects of agro-export growth. Its chief message is that the agronomic and economic characteristics of agro-export crops interact with the intrinsic...

The Extended Family and Intrahousehold Allocation: Inheritance and Investments in Children in the Rural Philippines
Provedor de dados: 31
Autores: Quisumbing,   Agnes R.
This paper examines the role of the extended family on investments in children, using data from a retrospective survey of three generations in the rural Philippines. Econometric results show that interactions between grandparent characteristics and child gender significantly affect the distribution of proposed land bequests between sons and daughters. However, grandparents significantly affect gender-specific investments in children's education only in resource-constrained families. Family-specific effects are more important in determining the pattern of investment in children within the nuclear family, while individual heterogeneity rather than family-specific unobservables dominates the extended family results. Interactions between parent characteristics...

The Effect of Distance and Road Quality on Food Prices, Marketing Margins, and Traders' Wages: Evidence from Zaire
Provedor de dados: 31
Autores: Minten,   Bart; Kyle,   Steven C.
Major investments in infrastructure rehabilitation have been undertaken by govemments, development banks and donors in developing countries in recent decades. In Sub-Saharan Africa roaddeterioration isperceivedtobeoneofthemaincausesforthelimitedsupplyresponseafter price liberalization in agricultural markets. Studies of the quantitative effects on marketing margins are rare. This analysis shows that the wholesale -producer food price margin is strongly influenced by the quality of the road infrastructure. Evidence from Zaire shows that food prices decrease faster than transportation costs increase and that traders' wages are higher on bad roads. A trader's model incorporating uncertainty in input costs is used to explain this phenomenon.

Assuming a competitive market, conditions are determined for when a steady-state equilibrium does not exist in the optimal dynamic management of a biological population. Irregular and unpredictable behavior (called “"chaos"”) can arise from fully rational economic decision making. High interest rate, adjustment costs, and an inelastic demand can contribute to market instability.

A COMPARISON OF NOMINAL AND REAL HISTORICAL RISK MEASURES
Provedor de dados: 31
Autores: Ford,   Beth Pride; Musser,   Wesley N.
Previous studies of historical risk have used either nominal or real data to calculate risk measures for agricultural prices and income. However, the effects of using nominal and real data have not been evaluated. This study utilizes theoretical variance approximation relationships to examine variances from detrended real and nominal time series. The relationships between variances are derived for quarterly U.S. farm milk prices for 1960-72, 1973-80, and 1981-90. Contrary to common intuitive arguments, results indicate that variances of real time series can be larger than variances of nominal series. While definitive conclusions are not possible, several reasons for using nominal data in risk analysis are given.

RATIONAL EXPECTATIONS ESTIMATION OF GEORGIA SOYBEAN ACREAGE RESPONSE
Provedor de dados: 31
Autores: Ahouissoussi,   Nicolas B.C.; McIntosh,   Christopher S.; Wetzstein,   Michael E.
The general method of moments procedure is used for estimating a soybean acreage response function assuming the producers hold rational expectations. Results indicate that soybean, corn, and wheat futures prices, lagged acreage, and government programs are significant factors for determining soybean plantings. Implications of the results are that crop acreage selection by Georgia producers is not very responsive to demand shocks. Thus, producers in other regions are more likely to absorb impacts from these shocks on crop acreage selection.

Autores: Morse,   George W.; Ha,   Inhyuck.
For several years, Business Retention and Expansion professionals have pointed out that BR&amp;E visitation programs appear to be relatively successful until it comes time to implement the plans developed in the BR&amp;E visitation program.  At the implementation stage, however, there have been very mixed reports.  A number of articles have documented the benefits of BR&amp;E visitation programs. Yet, none of these have examined the implementation of the strategic plans developed by BR&amp;E visitation programs.   Few communities would undertake the program if they did not expect to see some action on their plans.  Likewise, few state agencies or universities would continue to support BR&amp;E educational efforts if the BR&amp;E programs do not implement...

The Process of Farm Adjustment: A Critical Review
Provedor de dados: 31
Autores: Gow,   Jeff; Stayner,   Richard.
Farm adjustment is a complex process involving decisions by farmers about a wide range of economic and non-economic factors which influence the farm business and farm family. The economics literature emphasises the importance of economic factors in the adjustment behaviour of farmers. However, the observed adjustment behaviour of farmers does not correspond very closely to that predicted by that literature. Insights from the rural sociology and psychology literature offer new perspectives on farmer behaviour which are of relevance and use to both economic researchers and policy makers concerned with farm adjustment.

Land Markets, Employment, and Resource Use in the Peri-Urban Green Zones of Maputo, Mozambique: A Case Study of Land Market Rigidities and Institutional Constraints to Economic Growth
Provedor de dados: 31
Autores: Roth,   Michael J.; Boucher,   Stephen R.; Francisco,   Antonio.
Beginning in January 1991, the U.S. Agency for International Development funded a series of studies on land, employment, and financial markets in the peri-urban areas of Maputo. Beginning in September 1991, a land-market survey involving 121 households and 162 plots of land was administered in two peri-urban green zones of Maputo-districts 4 and 6. Households were queried about their land-settlement histories, mode of land acquisition, terms and conditions of transfer, land rights, size of holdings, perceptions of tenure security, land-use practices, commercial input use, hired labor, agricultural sales and revenues, nonfarm employment and earnings, and general demographic characteristics. The present study reports findings from the land-market survey...

THE IMPACT OF INFORMATION ON LAND DEVELOPMENT: A DYNAMIC AND STOCHASTIC ANALYSIS
Provedor de dados: 31
Autores: Batabyal,   Amitrajeet A.
In a two-period model, economists such as K.J. Arrow, A.C. Fisher, and C. Henry, have shown that when development is both indivisible and irreversible, a developer who ignores the possibility of obtaining new information about the outcome of such development will invariably underestimate the benefits of preservation and hence favor development. In this note, I extend the AFH analysis in two directions. I model the land development problem in a dynamic framework, explicitly specifying an information production function. In such a setting, I then ask and answer the question concerning when development should take place.  Forthcoming in Journal of Environmental Management

CONTINGENT VALUATION FOCUS GROUPS: INSIGHTS FROM ETHNOGRAPHIC INTERVIEW TECHNIQUES
Provedor de dados: 31
Autores: Johnston,   Robert J.; Weaver,   Thomas F.; Smith,   Lynn A.; Swallow,   Stephen K.
Despite the many important uses (and potential abuses) of focus groups in survey design, the CV literature presents few guidelines to aid moderators in their interaction with focus group participants.  This paper draws on the theory and practice of ethnographic interviewing to introduce general guidelines that can improve focus groups as an aid to CV research.  The proposed guidelines illustrate types of questions that should reduce speculation and moderator-introduced bias in focus group responses, and improve the correspondence between focus group responses and actual behavior.  The paper illustrates these ethnographic guidelines through a CV application concerning watershed resources.

Classification and Regression Trees (CART), a computer intensive nonparametric classification method, was used to model weekly Los Angeles wholesale prices (1990-93) for twelve different melon types. CART explained more of the variation in melon prices than did an ordinary least squares (OLS) regression with dummy variables. Explanatory variables ranked as the most-to-least important by CART are as follows: week, type of melon, year, size, grade, and shipping container. The most notable price change occurs when prices fall after 13 May.

DIVERSITY OF SOURCES FOR FRESH PRODUCE: IMPLICATIONS FOR LOCAL MARKETS
Provedor de dados: 31
Autores: Lohr,   Luanne; Hanson,   Steven D.
Number of suppliers, approximation of equal-shares market condition and market share held by in-state sources were calculated to determine diversity of sources for 10 fresh fruits and vegetables in eight U.S. wholesale markets. Specificity of growing conditions is associated with few supply sources, unequal market shares and limited purchases from in-state suppliers. For crops with few sources, lower perishability and greater transportability are correlated with greater balance in market shares. For crops with many supply sources, greater perishability and greater transportability are consistent with large market share from imports. Diversity across all commodities can increase market share for local producers.

Autores: Harvey,   David R.
Following an introduction explaining the genesis of the paper, section 2 briefly reviews some relevant literature and concepts. On the basis of this review, section 3 develops an outline evolutionary model of policy development. Section 4 interprets the history and present status of the EU policy within this framework (here illustrated by the cereals policy which is taken as archetypal for the CAP as a whole). It characterises the policy history In broad evolutionary terms, emphasising the 'fitness for purpose' of various manifestations of the policy organism. The key conclusion from this section is that the present policy situation cannot be described as 'fit' - there is too much conflict between the present (rather new) policy environment and the...

A Strategic Approach to Agricultural Research Program Planning in Sub-Saharan Africa
Provedor de dados: 31
Autores: Boughton,   Duncan; Crawford,   Eric W.; Howard,   Julie A.; Oehmke,   James F.; Shaffer,   James D.; Staatz,   John M.
Recent studies have shown that agricultural research can have high payoffs in Africa, but impact depends on how well technology fits with evolving needs and capacity in the agricultural sector and the rest of the economy. Structural adjustment policies (e.g., market liberalization, currency devaluation) and political change are transforming user demands for new technology and the economic environment in which technology must perform. The challenge is how to design agricultural research as a strategic input to promote broad-based economic growth, structural transformation, and food security in the increasingly market-driven, but fragile, economies of Africa.

Agriculture operates in an uncertain environment. Yields, prices, and resource usage can change dramatically from year to year. However, most analyses of the agricultural sector, at least those using mathematical programming methods, assume decision making is based on average yields, ignoring yield variability. This study examines how explicit consideration of stochastic yield outcomes influence a sector analysis. We develop a model that can be used for stochastic sector analysis. We extend the risk framework developed by Hazell and others to incorporate discrete yield outcomes as well as consumption activities dependent upon yield outcomes. An empirical application addresses a comparison between sector analysis with and without considerations of the...

Commodity Marketing Board Modernisation: The Queensland Experience
Provedor de dados: 31
Autores: Jarratt,   Ian S.; Brown,   Hannah.
This paper describes and explains the recent very rapid reduction in the number of commodity marketing boards (CMBs) in Queensland. The major causes included changed macro and micro economic policies, changes to national marketing arrangements, reduced producer support for compulsory delivery, producer interest in individual ownership of CMB assets, and producer demands for more flexible marketing systems. The key role of the Queensland Government in encouraging reviews of the CMBs, providing innovative and flexible legislative changes, and providing information and other assistance, is emphasised. Research on the effects of the changes in the commodity marketing arrangements is suggested.

Sources of Sectoral Growth in an Economy Wide Context: The Case of U.S. Agriculture
Provedor de dados: 31
Autores: Munisamy,   Gopinath; Roe,   Terry L.
Growth in US agriculture is linked to the non-farm economy through domestic terms of trade and factor market adjustments. With almost stable input growth, the relatively large contributions from growth in Total Factor Productivity (TFP) are off-set by declining real prices of primary farm products. The resulting net growth in value of farm output, at 0.25 % per annum, implies that the gains in TFP are shared by intermediate and final consumers of farm products. The decomposition of TFP suggests that public agricultural stock of knowledge and infrastructure are 'robustly' associated with TFP growth, while spill-overs from private agricultural and economy wide Research and Development (R&amp;D) are positive but, relatively small.

MODELING U.S. BUTTER CONSUMPTION WITH ZERO OBSERVATIONS
Provedor de dados: 31
Autores: Yen,   Steven T.; Su,   Shew-Jiuan.
A heteroscedastic double-hurdle model is used to investigate household butter consumption in the United States.  Results suggest that failure to incorporate heteroscedastic errors may lead to unreliable elasticity estimates.  Decomposition of the effects of variables leads to insightful information and makes the double-hurdle model a more useful tool in micro demand analysis.  Larger and higher-income households are more likely to consume butter than others and also consume more, but income elasticity is very small.  Age, region, and seasonality are among the other significant determinants of household butter consumption.

COMPUTER ADOPTION AND USE OF INFORMATION SERVICES BY NORTH CAROLINA COMMERCIAL FARMERS
Provedor de dados: 31
Autores: Amponsah,   William A.
The extent of information use by farmers for farm management is tracked in terms of computer adoption and usefulness, and the use of professional providers of information services. The study is based on a survey conducted in 1991, on North Carolina, as part of a regional project involving about fourteen states. The results revealed a low rate of computer adoption by the farmers surveyed. However, computer adoption and usefulness were explained by farm size, educational attainment and farm income. Also farmers' use of professional services, such as that provided by tax preparers and extension agents were positively influenced by farm size, age and educational level.

Autores: Trewin,   Ray; Weiguo,   Lu; Erwidodo; Bahri,   Sjaiful.
The high costs and effectiveness of Indonesia's current mix of policies aimed at maintaining rice self-sufficiency, for example fertiliser and other subsidies, has been questioned. Consequently, attention has turned to developing policies to increase farmers yields through efficiencies, for example as a result of better extension. The main issue investigated in this article is whether existing yields can be significantly improved through increasing the efficiency of individual farmers. Production frontiers are estimated and technical efficiencies/inefficiencies predicted from panel data and for one year at a time. Different results are explained in relation to a number of aspects, especially the rate of adoption of new technologies, and policy actions are...

STRUCTURAL SHIFTS IN THE TREATMENT OF INTERGOVERNMENTAL AID: THE CASE OF RURAL ROADS
Provedor de dados: 31
Autores: Deller,   Steven C.; Walzer,   Norman.
The effects of structural shifts in the treatment of intergovernmental aid during the 1980s are tested using a sample of 1,929 rural counties with local road responsibilities. A dynamic model is used to test the hypothesis that local public officials treated intergovernmental aid differently after the Reagan/Bush policy of Fiscal Federalism was implemented. Empirical findings from the dynamic model are that federal aid was much more simulative at the end of the decade than in earlier years but the effects of state aid remained the same throughout the 1980s. These differences are attributed to a perception that federal aid is less certain and more transitory than permanent.

AGRICULTURAL INDUSTRIALIZATION: IMPLICATIONS FOR ECONOMIC DEVELOPMENT AND PUBLIC POLICY
Provedor de dados: 31
Autores: Drabenstott,   Mark.
Industrialization is rapidly becoming a topic of great attention.  Driven by fundamental economic forces, industrialization seems likely to advance ore quickly in the coming decade to more industry segments.  By changing the way agriculture does business, industrialization will also bring change to public policy and agricultural institutions.  Commodity policy will increasingly be out of step with a product-oriented industry.  And as industrialization blurs the lines between producers and processors, land grant universities and the extension service will face challenges assessing who their customers are.

The impact of generic advertising and the free rider problem: a look at the U.S. orange juice market and imports
Provedor de dados: 31
Autores: Brown,   Mark G.; Lee,   Jonq-Ying; Spreen,   Thomas H.
Increased demand for an advertised product may increase price, which, in turn, may lead to a free rider problem where competitive imports increase and result in a smaller price increase than otherwise.  A study of Florida Department of Citrus advertising for orange juice indicated that the free rider problem has notably limited the impact of advertising on price in the U.S. market.  High U.S. orange juice demand, which in part has been a result of advertising, has attracted substantial amounts of orange juice imports.  Imports have eroded the impact of advertising on price by an estimated two-thirds.

A REVIEW OF THE PSYCHOLOGICAL LITERATURE ON RISK PERCEPTION IN TERMS OF CHANCE, HARM, AND CONTEXT
Provedor de dados: 31
Autores: Decker,   Bill D.
This review examines the psychological literature on risk perception in terms of van Ravenswaay's proposal of a broad-based definition of risk perception that includes the three concepts of chance, harm, and context.  The review further investigates the manner in which psychological researchers attempt to measure risk perception.  It is suggested that the majority of psychological research on risk perception does not address van Ravenswaay's concepts in a comprehensive manner.  This review of the psychological literature reveals that elements of van Ravenswaay's concepts are often employed as variables by psychological researchers, although not in a fashion similar to that suggested by van Ravenswaay.  It is proposed that van Ravenswaay's definition of...

PROSPECTS FOR U.S. DAIRY EXPORTS
Provedor de dados: 31
Autores: Dobson,   William D.
U.S. dairy companies and cooperatives have long been minor players in international dairy markets, exporting the equivalent of only 2% to 4% of domestic milk production. There are good reasons for this behavior. Sales opportunities in the large domestic market and prices offered by the USDA under the dairy price support program typically make export markets unattractive to U.S. dairy firms.

AGRICULTURAL PRODUCERS' WILLINGNESS TO PAY FOR REAL-TIME MESOSCALE WEATHER INFORMATION
Provedor de dados: 31
Autores: Kenkel,   Philip L.; Norris,   Patricia E.
Mesoscale weather networks can provide improved weather information to agricultural producers. This technology can potentially improve production decisions, reduce irrigation and pesticide inputs, and reduce weather-related losses. Developing a mesoscale network to disseminate real-time mesoscale weather information requires a substantial investment. In addition, there are costs associated with maintenance of the system and distribution of the information available. While public funds may be available to support initial development of the system, there may be less public support initial development of the system, there may be less public support for maintaining the system and subsidizing users’' access to the information.

A BARGAINING FRAMEWORK FOR THE GLOBAL COMMONS
Provedor de dados: 31
Autores: Bromley,   Daniel W.
The global commons represents a class of environmental problems that require international cooperation.  Global environmental problems arise because the actions of some individuals or governments in one location hold serious implications for individuals and governments in other locations.  There are global environmental policy problems because adversely-affected individuals (and governments) attempt to alter the behaviors of those responsible for global pollution.  We develop a framework with which to analyze such global environmental problems.  Our goal is to craft a resource management policy that will satisfy both those who seek a change and those who prefer the current situation.  This environmental incentive policy will align the interests of the two...

Green Giving: An Analysis of Contributions to Major U.S. Environmental Groups

Autores: Richer,   Jerrell.
Data are compiled from the tax records of 29 major environmental organizations for the period 1980-1994 to identify factors that influence voluntary contributions. I examine the effects of organizational characteristics, such as fundraising expenditures and alternative sources of revenue, along with the impact of general economic conditions and the political climate. I find that government grants to the organizations had a positive and statistically significant impact on voluntary contributions rather than a crowding out effect. Contributions were price inelastic, where the price is defined as the effective cost to the donor of achieving a one-dollar increase in the provision of program services. Resources devoted to fundraising had a strong and positive...

Measuring Food Insecurity: The Frequency and Severity of "Coping Strategies"
Provedor de dados: 31
Autores: Maxwell,   Daniel G.
Defining and interpreting food security, and measuring it in reliable, valid and cost-effective ways, have proven to be stubborn problems facing researchers and programs intended to monitor food security risks. This paper briefly reviews the conceptual and methodological literature on food insecurity measurement, describes a particular method for distinguishing and measuring short-term food insecurity at the household level, and discusses ways of generalizing the method. The method developed enumerates the frequency and severity of strategies relied on by urban households when faced with a short-term insufficiency of food. This method goes beyond more commonly-used measures of caloric consumption to incorporate vulnerability elements of food insecurity as...

The Relative Importance of the Green Industry in the U.S. Agricultural Economy
Provedor de dados: 31
Autores: Turner,   Steven C.; Kriesel,   Warren.
This article describes the relative size of the green industry within the U.S. economy and how it is linked to supporting industries through the volume of transactions and economic impact multipliers. This analysis was based on IMPLAN, an input-output model developed by the U.S. Forest Service. In terms of 1990 employment, the green industry was the second leading employer in United States production agriculture. In terms of output, the greenhouse and products sector ranked sixth within production agriculture, behind cattle, other livestock, grains, other crops and oil bearing crops.

Program Participation and Farm-Level Adoption of Conservation Tillage: Estimates from a Multinomial Logit Model
Provedor de dados: 31
Autores: Babcock,   Bruce A.; Chaherli,   Nabil M.; Lakshminarayan,   P.G.
The conservation compliance provision of the 1985 Food Security Act requires highly erodible land to be cropped according to a locally approved conservation plan. There is overwhelming evidence that conservation compliance has reduced soil erosion. A key issue confronting Congress as they consider 1995 Farm Bill options is the fate of these erosion benefits if commodity programs are eliminated or it the subsidy level is greatly reduced.  This study provides policymakers with additional insights into the relationship between conservation tillage practices and government programs by using observed farmer behavior.  The central question addressed is: If future program benefits are not tied to conservation practices, will there be a significant decline in the...

THE RETURNS FROM RESEARCH IN AUSTRALIAN BROADACRE AGRICULTURE
Provedor de dados: 31
Autores: Mullen,   John D.; Cox,   Thomas L.
Many people share the view that too little is invested in R &amp; D in agriculture. The relationship between several measures of productivity and research expenditure was estimated using data from ABARE's surveys of broadacre industries and a new data series on R &amp; D expenditure for the period 1953 to 1988. The internal rate of return to research was estimated to be in the range of 15 to 40 percent which does not provide strong evidence that Australia is either under- or over-investing in public research.

Consumption of Home-Delivered Foods: Results from an Exploratory Survey
Provedor de dados: 31
Autores: Nayga,   Rodolfo M., Jr.; Farooq,   Zafar.
This study examines the effect of various factors on the decision to consume home-delivered foods. The results of the study suggest that the decision to order food for home delivery is determined by gender, price consciousness, number of adults and children in the household, employment status, education level, ownership of microwave oven and, to some extent race, age and income. Specifically, the results suggest that less price-conscious, employed, higher-educated, white males within the 25-34 age group, in a household with a microwave oven, with smaller number of adults, but with children are more likely to purchase home-delivered food that others.

Participants in the Louisiana sugar cane industry have provided little information related to the efficiency of sugar processing operations. Using panel data from the population of Louisiana sugar processors, alternative model specifications are estimated using stochastic frontier methods to measure the technical efficiency of individual sugar factories. Results suggest the Louisiana sugar processing industry is characterized by a constant returns to scale Cobb-Douglas processing function with high technical efficiency.

VALIDATING CONTINGENT VALUATION WITH SURVEYS OF EXPERTS
Provedor de dados: 31
Autores: Boyle,   Kevin J.; Welsh,   Michael P.; Bishop,   Richard C.; Baumgartner,   Robert M.
Contingent-valuation estimates for white-water boating passengers are compared with Likert ratings by river guides.  The approach involves asking whether passengers and their guides ordinally rank alternative flows the same.  The National Oceanic and Atmospheric Administration's Contingent Valuation Panel (1993) suggested "one might want to compare its (contingent-valuation's) outcome with that provided by a panel of experts."  River guides constitute a counterfactual panel of "experts."  For commercial trips, optimum flows are 34,000 cfs and 31,000 cfs for passengers and guides, and the comparable figures for private trips are 28,000 cfs and 29,000 cfs.  In the NOAA Panel framework, passengers can evaluate the consequences of various river flows and...

Models are developed to measure the effect of socioeconomic factors on the probability of consuming fish and shellfish in both the away from home and at home markets.  Factors that significantly affect the likelihood of eating fish and shellfish at home include urbanization, region, race, ethnicity, age, diet status and income.  On the other hand, region, employment, diet status, household size, age and income significantly affect the likelihood of eating fish and shellfish away from home.

This article examines some difficult decisions that agricultural economists must confront in doing research. Over many years, rules and standards have developed in agricultural economics that guide researchers, providing an underlying framework for research methods. This article deals with applying these seldom discussed guidelines to specific research situations confronted by agricultural economists. With this article, we hope to stimulate a dialogue among agricultural economists about the need for additional, appropriate methodological guidelines in agricultural economics research.

Recent Developments in Food Retailing in the United States and Australia
Provedor de dados: 31
Autores: Nayga,   Rodolfo M., Jr.; Riethmuller,   Paul C.
The food retailing sectors of the United States and Australia are large industries that are increasingly driven by consumer needs and wants. Both industries are changing to keep pace with social and economic developments. The premises are getting larger and one-stop shopping is becoming more common. The rationing of shelf spare has become an issue. Information technology is providing stores with better information on product movement and sales performance. There is a common movement away from city centres to affluent suburban centres. In Australia, the retailing industry is concentrated in fewer owners than in the US. Future research on retail concentration, trade with processors, and international competitiveness would be worthwhile.

U.S. HOUSEHOLD CONSUMPTION OF FRESH FRUITS

Autores: He,   Hua; Huang,   Chung L.; Houston,   Jack E.
This study uses the 1987-88 U.S. Department of Agriculture Nationwide Food Consumption Survey data to analyze the impacts of income, prices, and selected socioeconomic characteristics on household consumption of fresh fruits. Results suggest that fresh fruits are considered economic necessities, with own prices significantly influencing consumption. Cross-price effects are generally weak and insignificant, but the number of adults in the age group 18-64 is an important determinant of household consumption of fresh fruits. While nutrition information and household savings have significant, positive influences on most fresh fruit consumption, the presence of a working wife has a significant and negative influence.

Autores: Betubiza,   Eustacius N.; Leatham,   David J.
A tobit econometric procedure was used to examine the effect of selected demand and supply factors on nonreal estate agricultural lending by commercial banks in Texas.  Results show that banks have reduced their agricultural loan portfolios in response to increased use of interest sensitive deposits after deregulation.  Moreover, almost half of this decrease came from banks that stopped making agricultural loans.  Also, results show that banks affiliated with multi-bank holding companies lend less money to agriculture relative to their assets than do independent banks.

ECONOMIC ANALYSIS OF THE IMPACTS OF BOVINE SOMATOTROPIN ON THE PROFITABILITY OF REPRESENTATIVE DAIRY FARMS IN THE NORTHEAST
Provedor de dados: 31
Autores: Elbehri,   Aziz; Yonkers,   Robert D.
This study evaluated the impacts of bST on the profitability of representative Pennsylvania dairy farms using a stochastic simulation model under two initial milk yield-per-cow levels, three levels of milk response to bST, and three milk price forecast scenarios.  Results showed that farm profitability was improved with bST, but the magnitude of the benefits from bST depended on the farm's initial milk output per cow and the level of milk response to bST, both of which are related to quality of management.  However, modest price declines due to bST-induced increases in the milk supply would have an offsetting effect on farm profitability.

MARGINAL PRICE OF LAKE RECREATION AND AESTHETICS: AN HEDONIC APPROACH
Provedor de dados: 31
Autores: Lansford,   Notie H., Jr.; Jones,   Lonnie L.
Efficient allocation of water requires knowledge of water's value in both consumptive and nonconsumptive uses. This study estimates the marginal value of water in lake recreational and aesthetic (RA) use. An hedonic price equation (employing the Box-Cox functional form) indicates lake front location, distance to lake, and scenic view are significant RA characteristics of housing. Water front properties command a premium price for the private access they offer. Beyond the water front, the marginal RA price falls rapidly with increasing distance, becoming asymptotic to some minimum. Twenty-two percent of housing price is found to be attributable to the RA component.

A long term whole farm analysis comparing conventional and low-input farming systems is reviewed.  A computational error led to the mistaken conclusion that conventional farming with government programs is less preferred by risk-averse farmers than the low input alternative.  The greater income variance of conventional agriculture need not make it less preferred provided a higher mean income sufficiently offsets the higher variance.

Hedonic Pricing of Dairy Bulls - An Alternative Index of Genetic Merit
Provedor de dados: 31
Autores: Richards,   Timothy J.; Jeffrey,   Scott R.
This study investigates the use of hedonic pricing to identify the value of relevant production and type traits for dairy bulls in Alberta. A hedonic pricing model is estimated that models semen price as a function of individual production and longevity characteristics for a sample of Holstein bulls. This model corrects for sources of statistical bias in the data (i.e., censored data and endogenous supply problems). The results suggest that the most important characteristics in valuing dairy bulls are milk volume, protein and fat content, general conformation, body capacity, the popularity of the bull, and the probability that the bull's semen may be in short supply. This methodology may be used to establish a method of forecasting semen prices for newly...

Farm Lending Program Challenges for the Farm Service Agency
Provedor de dados: 31
Autores: LaDue,   Eddy L.
One set of programs that are the responsibility of the new (Consolidated) Farm Service Agency (FSA) is the farmer loan programs of the former Farmers Home Administration (FmHA). As FSA attempts to integrate and coordinate the former FmHA, Agricultural Stabilization and Conservation Service (ASCS) and Federal Crop Insurance programs, the farm credit programs will pose some particular challenges. The purpose of this paper is to discuss some of the issues relative to the farm credit programs that may be important in understanding and dealing with these challenges. Topics covered include the rationale for government lending to farmers, a historical perspective on farm credit programs, a short review of our experience with the important farm loan programs, a...

Impact of the Structural Adjustment Program on Agricultural Production and Resource Use in Egypt
Provedor de dados: 31
Autores: Hazell,   Peter B.R.; Perez,   Nicostrato D.; Siam,   Gamal; Soliman,   Ibrahim.
This paper uses an agricultural sector model to evaluate the effects of an ambitious and ongoing policy reform program on agricultural production and resource use in Egypt. The results show that Egypt has already gained from the policy reforms, but that much larger gains depend on increased exports of high value crops. Water is found to be emerging as an important constraint on agriculture, and it will be essential to establish more effective institutional and pricing mechanisms to encourage greater water use efficiency in the future. Because many of the new lands compete with the more productive lands of the Nile delta for water, the economic return to the development of new lands is also found to be low. The policy reforms are not likely to lead to...

The Role of Local Cooperatives in the Emerging Swine Industry
Provedor de dados: 31
Autores: Hogeland,   Julie A.
At least 12 reasons could propel cooperatives into a greater role in the swine industry; among them, protecting their market share in feed and offering a cooperative alternative to existing marketing channels. Yet, the industry offers a special challenge during the mid-l 990s because structural upheaval is completely redefining traditional methods of production and marketing. As a foundation for future efforts, the Cooperative Services program of USDA’s Rural Business and Cooperative Development Service and 5 regional cooperatives surveyed 1,314 local cooperatives in 1993. Results indicated local cooperatives urgently wanted greater direction and leadership from their regionals. They also wanted financial backing to offer member swine producers financing...

TRANSACTION COSTS, FADS, AND POLITICALLY MOTIVATED MISDIRECTION IN AGRICULTURAL RESEARCH
Provedor de dados: 31
Autores: Huffman,   Wallace E.; Just,   Richard E.
This paper examines efficiency implications of national and local policies for fund allocation and management of agricultural research, which produce pure and impure public goods.  The possibility is examined that competitive grants programs increase rent seeking activities by scientists relative to specific block grants or formula allocations and thereby reduce both the real resources available to produce traditional research outputs and the productivity with which research resources are used.  Management of local research units, including advantages of incentive compatible contracts, is also considered.  Additional conceptual and empirical work are needed before the issues are resolved.

REGULATION OF NITROGEN POLLUTION: TAXES VERSUS QUOTAS
Provedor de dados: 31
Autores: Choi,   E. Kwan; Feinerman,   Eli.
This paper investigates the effects of first-best policies to regulate nitrogen application. Some nitrogen fertilizer is applied ex ante before a random rainfall, but sidedressed nitrogen may be applied ex post. First-best policy is a tax or a quota on ex ante application, because sidedressed nitrogen is not leached. Since a risk-averse farmer uses more nitrogen ex ante than a risk-neutral farmer, a higher tax must be imposed on the former.  Action equivalent first-best taxes and quotas are also welfare equivalent. An empirical model for wheat in Israel was used to demonstrate the analytical findings.

The Impact of International Prices and Exchange Rates on Domestic Food Prices in Zaire
Provedor de dados: 31
Autores: Minten,   Bart; Kyle,   Steven C.
In sectoral trade analysis, agriculture is generally assumed to be a tradable sector. However, this is not the case within the time frame envisioned for policy reform programs in many developing countries. In this time frame, there are no agricultural products that can be classified as purely tradable or non-tradable. Evidence from Zaire shows that exchange rate changes have a differential impact on agricultural products depending on the characteristics of the product. The classification between tradable and non-tradable is not clear cut as the price of some non-tradables is also affected by changes in the international market or changes in the exchange rate.

THE QUEUING THEORETIC APPROACH TO GROUNDWATER MANAGEMENT
Provedor de dados: 31
Autores: Batabyal,   Amitrajeet A.
In this paper I propose and develop a new framework for modeling groundwater management issues. Specifically, I apply the methods of queuing theory—for the first time, to the best of my knowledge—to model a groundwater management problem from a long-run perspective. I characterize two simple management regimes as two different kinds of queues and then show how to pose a manager's decision problem as an optimization problem using queuing theoretic techniques. I solve for certain fundamental quantities, such as the expected system size, and then discuss the economic meaning and relevance of the queuing concepts being used. I close by discussing possible extensions to my basic models.  Published in Ecological Modelling 85 (2-3, 1996):219-27.

A RENEWAL THEORETIC APPROACH TO ENVIRONMENTAL STANDARD SETTING
Provedor de dados: 31
Autores: Batabyal,   Amitrajeet A.
The process of environmental regulation is usually a two-step one. In the first step, a standard for environmental quality is set. Then, in the second step, a regulatory mechanism is put in place to achieve the standard. In this paper I show how renewal theory can be used to set the quality standard optimally.

A NEW ALGORITHM FOR COMPUTING COMPENSATED INCOME FROM ORDINARY DEMAND FUNCTIONS
Provedor de dados: 31
Autores: Dumagan,   Jesus C.; Mount,   Timothy D.
This paper proposes a REversible Second-ORder Taylor (RESORT) expansion of the expenditure function to compute compensated income from ordinary demand functions as an alternative to the algorithm proposed by Vartia. These algorithms provide measures of Hicksian welfare changes and Konus-type cost of living indices. RESORT also validates the results by checking the matrix of compensated price effects. obtained through the Slutsky equation, for symmetry and negative semi-definiteness as required by expenditure minimization. In contrast, Vartia's algorithm provides no validation procedure. RESORT is similar to Vartia's algorithm in using price steps. It computes compensated income at each step "forward" from the initial to the terminal prices, and insures...

OPTIMAL DESIGN OF A VOLUNTARY GREEN PAYMENT PROGRAM UNDER ASYMMETRIC INFORMATION
Provedor de dados: 31
Autores: Wu,   JunJie; Babcock,   Bruce A.
Green payment programs, where the government pays farmers directly for environmental benefits, are an alternative to the current method of achieving environmental benefits which restricts farming practices in exchange for deficiency payments. This article presents a voluntary green payment program using the principles of mechanism design under asymmetric information. Information asymmetry arises because the government knows only the distribution of farmers’' production situations, rather than farm-specific information. The program is demonstrated with irrigated corn production in the Oklahoma high plains. A green payment program can reduce budget costs and pollution, while increasing the net social value of corn production.

Modelling Government Processes and Policies in Agriculture: A Review
Provedor de dados: 31
Autores: Johnson,   R.W.M.
In this paper, political preference functions and bargaining models based on game theory are examined for their relevance to government processes and policies in agriculture. While bargaining models show some refinements over preference models in explaining how interest group demands are met in a modern society, the results appear to still fall short of a well-documented understanding of the political economy and institutions involved in policy decisions. In practical terms, economic modelling is too time-consuming and elaborate to inform everyday decisions of government but an understanding of the principles involved and previous results of this kind of analysis can inform the work of both policy advisors and decision makers.

Taxes, Tax Subsidies and the Impact of Trade Agreements
Provedor de dados: 31
Autores: Perry,   Gregory M.
Tax subsidies are an often overlooked method by which government subsidises agriculture. An examination of tax policies in Australia, Canada, Germany and the United States reveals several different tax subsidies provided to farmers in these countries. Most of these subsidies are in theory subject to reduction under GATT. For various reasons, however, most tax subsidies are not included in subsidy measures. Failure to include these kinds of subsidies in AMS measures could encourage their proliferation among countries desiring to continue agricultural subsidies.

CONSISTENCY AND OPTIMALITY IN A DYNAMIC GAME OF POLLUTION CONTROL I: COMPETITION
Provedor de dados: 31
Autores: Batabyal,   Amitrajeet A.
I model the interaction between a regulator and polluting firms as a Stackelberg differential game in which the regulator leads. The firms create pollution, which results in a stock externality. I analyze the intertemporal effects of alternate pollution control measures in a competitive industry. The principal issue here concerns the dynamic inconsistency of the optimal solution. Inter alia, I compare the steady state levels of pollution under optimal and under time consistent policies.   Forthcoming in Environmental and Resource Economics

DETERMINANTS OF FARM PRODUCTIVITY AND THE SIZE-PRODUCTIVITY RELATIONSHIP UNDER LAND CONSTRAINTS: THE CASE OF RAWANDA
Provedor de dados: 31
Autores: Byiringiro,   Fidele Usabuwera.
Despite its importance in agricultural development, the oft-observed inverse relationship between farm size and land productivity in developing countries has received very limited attention in Africa. This work tries to fill the gap by analyzing the relationship between farm-size and productivity in Rwanda.  Our results confirm the existence of an inverse relationship between farm-size and land productivity. Smaller farms have a lower opportunity cost of labor and a higher shadow price of land compared to larger farms. These disparities are the results of constraints faced by smaller farms (a) to access land, and (b) to access labor market opportunities. The observed relationship is affected by land quality proxied by erosion (average annual soil loss),...

The influence of socioeconomic variables on nutrient intake is studied using nonparametric procedures that admit estimation of multivariate functions. The analysis indicates a nonlinear relation between intake, age, education, and income. Specifically, intake rises with income reaching an inflection point beyond which it is essentially flat. Socioeconomic variables influence intake primarily at lower income levels. Nonparametric procedures prove useful in avoiding ad hoc specifications that would fail to uncover these findings.

DEREGULATION AND EFFICIENCY IN GRAIN TRANSPORT
Provedor de dados: 31
Autores: Brennan,   Donna C.
In this paper, it is argued that removing restrictions on road transport will not be sufficient to encourage efficiency improvements in grain freight industry while rail authorities continue to operate as public monopolies. This is because of the structure of costs in the grain freight industry, which imply that road transport cannot compete with rail transport in areas where road is the more efficient mode. While the tendency for a regulated monopoly to cross-subsidise inefficient operations is common place, the focus in this analysis is on the nature of the cross-subsidy in the grain freight industry, and shows that it is a type of cross-subsidy that is well hidden by aggregation. A model of investment in a rail network is presented where the monopoly...

A healthy, shallow, draft barge industry is essential to the well-being of U.S. agriculture.  Sixty percent of U.S. farm grain, oilseed and feed exports (which is 25 percent of the world trade in grain and oilseeds) is transported on the Mississippi River system. This low cost transportation system is also used to transport 25 percent of U.S. farm fertilizer and is important for other farm inputs.  U.S. farm exports are a major factor in reducing our balance of payments deficit and maintaining the strength of the dollar.

FACTORS AFFECTING U.S. DEMAND FOR REDUCED-FAT MILK
Provedor de dados: 31
Autores: Gould,   Brian W.
U.S. fluid milk consumption has changed dramatically since the early 1970s. Whole milk accounted for over 81% of commercial fluid milk disappearance in 1970. By 1993, this percentage was less than 39%. A three-equation fluid milk demand system is estimated for fluid milks that vary by fat content. The household panel data set used includes over 4,300 households who recorded fluid milk purchased for at-home consumption over a 12-month period. Given that many of these households did not consume one or more of the three milk types, the econometric model explicitly incorporates the censored nature of these commodity demands. Own and cross-price and substitution elasticities are estimated along with effects of household demographic characteristics.

End-of-year financial data from 700 farms enrolled in North Dakota Farm Business Management Education Program for the years 1992 to 1994 are analyzed according to 16 financial standards.  All median profitability measures, median term debt coverage, term debt and capital margin, and median net farm income as a percent of gross revenue are lower in 1994 than in 1993.  The median for all 16 financial measures deteriorated for 1994 in the south central and west regions due to lower livestock profitability.  Financial performance of the north central region improved each of the three years.

AIR POLLUTION AND FARM-LEVEL CROP YIELDS: AN EMPIRICAL ANALYSIS OF CORN AND SOYBEANS
Provedor de dados: 31
Autores: Westenbarger,   David A.; Frisvold,   George B.
While many studies have estimated the impacts of air pollution on crop yields on experimental plots, few have estimated these impacts under actual farm production conditions.  This study econometrically estimates the impact of air pollution on corn and soybean yields, controlling for weather, soil quality and management practices, using farm-level data for the eastern United States.  Ozone pollution was found to reduce yields for both crops.  The mean elasticity of yield with respect to ozone exposure was -0.19 for corn and -0.54 for soybeans.  The benefits of ozone standards to protect crops, measured in terms of crop revenues, range from $17 to $82 million depending on the stringency of the standard.  Over 85 percent of the revenue gains are captured by...

The profitability of planting flood tolerant crops in flood plains relative to traditional row crops is evaluated under different assumptions concerning flood frequency and the level of government crop subsidy.  The alternative crops evaluated are short rotation woody crops and herbaceous energy crops.  The analysis is conducted for two growing environments: Louisa County, Iowa and Saline County. Missouri.  The economic indicator used to value the alternative scenarios is annualized net return per acre.  This indicator can account for the significant time lags between planting and harvesting of the two alternative crops.  The results indicate that row crops dominate the flood tolerant crops until flood frequency approaches 50 percent. The positive...

Consumers’ concerns about food attributes related to health, safety and nutrition were ascertained by way of a mailed survey in the metropolitan area of St. Paul/Minneapolis, Minnesota, in 1993.  An ordered probit analysis was conducted to determine how these concerns correlated with eating habits - specifically increasing, decreasing or making no change in the consumption of various types of meats.  Those who had decreased their beef consumption were concerned about their intake of sodium, fat and cholesterol.  They also preferred a variety of foods and tended to be older and better educated.  Taste, appearance and guaranteed safety ranked high on a list of food attributes consumers preferred.

Transition to a New World Economic Order Part I: The Framework
Provedor de dados: 31
Autores: Calkins,   Peter H.
The idea of a new world order suggests political and economic changes that would improve the lot of all the people in the world. Such a new world order would address all causes of poverty and inequality both within nations and between nations. Desirable changes would modify present competitive patterns of organisation and substitute more cooperative systems and processes. Writers in this area focus particularly on how to change the current state of the world in order to achieve a transition to a more desirable new world order. From an economic point of view, this transition could be interpreted as an attempt to frame new political, economic and social institutions and rules of conduct that would enable the equity goals of the proposers to be achieved.

Farm Computer Uptake and Practices in New Zealand
Provedor de dados: 31
Autores: Nuthall,   Peter L.; Bishop-Hurley,   G.J.
There is wide interest in both management circles and service industries in forecasts of the future uptake of computers on farm and horticultural businesses. Similarly, knowledge of how computer owning managers are utilizing them is of interest. From a 1992/93 postal survey of a stratified random sample of New Zealand producers it was determined that of the 24 per cent with computers, 19 per cent used them for business purposes and 5 per cent solely for entertainment and other non-business functions. An analysis of the length of past and anticipated ownership suggests New Zealand farmers are near the maximum uptake rate on the traditional sigmoid adoption curve. Existing ownership was positively correlated with farmer education level and farm size. On...

PRICE AND QUANTITY EFFECTS OF CANADA'S DAIRY ADVERSTISING PROGRAMS
Provedor de dados: 31
Autores: Kinnucan,   Henry W.; Belleza,   Evelyn T.
An equilibrium-displacement model is combined with econometric estimates of key model parameters to identify the impacts of Canada's dairy advertising programs on prices and quantity.  Results suggest increased advertising of fluid milk enhances the farm value of milk but has minimal effect on government costs of the dairy price-support program.  Owing to government intervention in the butter market, increased butter advertising has no effect on the farm value of milk, at least in the short run, but is highly effective at reducing government costs.  Advertising is most effective, ceteris paribus, in markets where retail demand and wholesale supply for the specific dairy product are relatively price inelastic.

The Expansion of Japanese Food Processors in the Asia-Pacific Region
Provedor de dados: 31
Autores: Riethmuller,   Paul C.; Chai,   Joseph C.H.
Japanese food processors have been faced with internal and external squeezes in recent years. Internally, the industry is faced with an overall demand ceiling due to Engel's law and a rapidly changing demand structure due to the "westernisation" of the Japanese consumers' taste. Externally, the industry is faced with increased import competition as a result of the liberalisation of the Japanese import market for agricultural and processed food products. Under these pressures, performance of the Japanese food processors in terms of productivity and profitability, is found to be below average, compared with Japanese manufacturing as a whole. Associated with the deteriorating productivity and profitability performance, Japanese food processors have stepped up...

This paper discusses a paper presented by Steven Smith at the 1995 annual meeting of the Northeastern Agricultural and Resource Economics Association.  Smith presented key issues that have changed the context for rural development policy in the United States.  We propose that the induced innovation model of economic development can be used to identify a variety of ways that LGU's can contribute to developing and delivering appropriate rural economic development programs.  These ways include assisting rural communities in identifying comparative advantage, identifying and/or providing relevant resource persons, delivering appropriate educational programs and conducting research on important issues.  The success of LGU's in these areas will depend on their...

Monte-Carlo simulation of nonparametric efficiency shows that even when the number of firms is large, defining ten or more inputs results in most firms being measured as efficient.  Comparison of the simulated results with any empirical results may suggest that the dimension of the problem, rather than actual efficiencies, determines computed efficiencies.

DETERMINANTS OF COW-CALF PAIR PRICES
Provedor de dados: 31
Autores: Parcell,   Joseph L.; Schroeder,   Ted C.; Hiner,   Frina D.
Cow-calf prices are determined by interaction of many factors. At a particular auction, cow-calf pair prices often had a range of 75% of the mean price. This variability suggests that producers need to be informed regarding cow-calf price determinants. This study uses auction data during 1993 to estimate price differentials associated with cow-calf  pair characteristics using a hedonic model. Cow breed, age, health, conditions, horns, frame, and whether the cow had been bred back were significant price determinants. Calf weight, health, and frame had significant price impacts. Highest prices were paid for pens containing 9-12 pairs of young Angus, dehorned, bred back, healthy cows with heavy healthy calves.

Autores: Nelson,   Robert G.; Turner,   Steven C.
Perceived characteristics of thin markets are described and approaches to furthering their study are suggested.  Design features of a laboratory thin market, patterned after a typical livestock marketing situation, are described.  Price bias and variation from a "thick" private negotiation market with 22 traders is compared to that from a "thin" auction market with 8 traders.  No systematic price bias was found in any of the markets.  Price variation was actually lower in the thin auction market.

Autores: McGuirk,   Anya M.; Driscoll,   Paul J.; Alwang,   Jeffrey Roger; Huang,   Huilin.
A misspecification testing strategy designed to ensure that the statistical assumptions underlying a system of equations are appropriate is outlined. The system tests take into account information in, and interactions between, all equations in the system and can be used in a wide variety of applications where systems of equations are estimated. The system testing approach is demonstrated by modeling U.S. consumer demand for meats. The example illustrates how the approach can be used to disentangle issues regarding structural change and other forms of model misspecification.

U.S. IMPORTS OF CANADIAN WHEAT: ESTIMATING THE EFFECT OF THE U.S. EXPORT ENHANCEMENT PROGRAM
Provedor de dados: 31
Autores: Haley,   Stephen L.
It is hypothesized that the U.S. Export Enhancement Program (EEP) has had a role in increased U.S. imports of Canadian wheat. Using a set of world wheat models that differentiate wheat according to class and source, several conclusions concerning the role of EEP are reached. Over the period 1986-1993, EEP has been accountable for 40 to 48 percent of the yearly growth in U.S. imports of Canadian wheat. EEP subsidies in 1991/92 to China and Brazil caused significant diversion of Canadian wheat that would have been destined for those markets instead to the U.S. market. Further, it is argued that a quota on imports is not likely to have price-enhancing effects for U.S. wheat.

EXPORT SUPPLY RESPONSE OF THE AUSTRALIAN CITRUS INDUSTRY
Provedor de dados: 31
Autores: Gunawardana,   P.J.; Kidane,   Habtom; Kulendran,   N.
A model of export supply response of the Australian citrus industry is developed and estimated using cointegration and error correction techniques and quarterly data for the period 1983 to 1993. The estimates suggest that, even in the long run, the supply of citrus exports is inelastic with respect to relative price. The results also show that the adjustment of export supply to changes in relative price is not instantaneous, the domestic production capacity has a significant positive impact on export supply, and export supply in the June quarter in each year is significantly lower than in other quarters.

A COMPARISON OF SUSTAINABLE AND CONVENTIONAL FARMERS IN NORTH DAKOTA

Autores: Sell,   Randall S.; Goreham,   Gary A.; Youngs,   George A., Jr.; Watt,   David L.
Interviews and mail-out/mail-back surveys were conducted in 1992 with 38 conventional and 41 sustainable North Dakota farmers. The results emphasize the differences and similarities of these two types of farmers.  Sustainable farms had more diverse cropping practices and were more likely to raise alternative crops like alfalfa, buckwheat, hay, millet, oats, and rye than conventional farmers.  Conventional farmers were more likely to raise traditional crops like barley, sugar beets, sunflowers, and spring wheat. Conventional farmers averaged substantially higher crop yields than sustainable farmers.  Three-fourths of the sustainable farmers raised livestock compared with one-half of the conventional farmers. Conventional farmers had greater equity, assets,...

Environment, Welfare and Gains from Trade: A North-South Model in General Equilibrium
Provedor de dados: 31
Autores: Diao,   Xinshen; Roe,   Terry L.
The effects of environment on trade and welfare are analyzed in a modified Heckscher-Ohlin framework using a quasi-homothetic preferences to account for differences in countries' expenditure shares on health. Three types of pollution, local-disembodied, global-disembodied and embodied, result as a by-product of inputs used in production. For each case, the Walrasian, Pareto optimal and the Regulators' problem are analyzed. The optimal tax is shown to improve each country's welfare if the country is small in the world market. Otherwise, changes in the terms of trade may cause one country to be made better off at the expense of the other. Interdependence for the global-disembodied case is explored using a one-shot Nash game. For the embodied pollution,...

Against the background of increasing interest in closer economic relations in the Middle East, the contribution that greater integration of markets might make to improving food security in the region is investigated, using a quantitative framework for gauging the reduction in instability of market supplies for cereal, meat, and dairy commodities under regional cooperation schemes versus more general policies to increase the integration of Middle East markets with markets in Western Europe and the world at large. Nondiscriminatory trade liberalization yields the greatest improvements in food security, but expansion of intra-regional trade relations also result in improved food security, except in the case of wheat and other cereals because of already...

Executive Compensation Patterns and Practices in Minnesota and Wisconsin Cooperatives
Provedor de dados: 31
Autores: Trechter,   David D.; King,   Robert P.
Cooperatives face unique challenges in compensating managers because it is more difficult to link the financial interests of the manager to those of the cooperative. One way to overcome this challenge is to use performance-based bonuses. This study of cooperatives in Minnesota and Wisconsin found that such bonuses are infrequently used. Further. evidence indicates that existing bonuses tend to be linked more to the size of the cooperative (sales. assets) than to profitability. These results suggest that more attention to this critical area is warranted.

MODIFYING THE NEO-CLASSICAL APPROACH TO TECHNOLOGY ADOPTION WITH BEHAVIORAL SCIENCE MODELS
Provedor de dados: 31
Autores: Lynne,   Gary D.
The dualistic nature of humans has been recognized for centuries.  The intriguing question is the extent to which the human being with her/his display of concern for others can simultaneously act as an egoist, the latter being descriptive of the homo oeconomicus rendition of the human.  Multiple utility theory suggests a way to approach research on such issues.  A test case of water conserving technology adaptation behavior by Florida growers is examined.  Empirical evidence supports moving toward an expanded version of the mono-utility or I-utility model to include a We-utility.

TRADE CREATION AND DIVERSION EFFECTS OF THE NORTH AMERICAN FREE TRADE AGREEMENT OF U.S. SUGAR IMPORTS FROM MEXICO
Provedor de dados: 31
Autores: Devadoss,   Stephen; Kropf,   Jurgen; Wahl,   Thomas I.
A world sugar model consisting of 21 countries was developed to determine the effects of NAFTA of U.S. and Mexican sugar markets and to quantify the trade creation and diversion effects on U.S. imports from Mexico. Mexican sugar production increases under NAFTA, causing Mexico to become a net exporter. NAFTA induces sugar imports from Mexico to displace U.S. production, to meet demand expansion, and also to divert U.S. imports from other foreign suppliers to Mexico. Effects of NAFTA on the U.S. sugar market are small because of the side agreements which limit Mexican exports and which include corn sweetener consumption when computing Mexico's production surplus.

The objective of this paper is to develop a cost-benefit model that presents an analysis of the costs of implementing safe agrichemical practices, being the use of recommended protective equipment, and the benefits derived from these practices, being the reduced risk of consequent health problems.  Initially, the cost-benefit analysis relies on surveys of the prevalence of short term acute cases of agrichemical poisoning among farmers and farm workers (inclusively termed farmers in the study), and epidemiological research on the elevated risks of cancer for farmers. The increased risks of health problems due to agrichemical exposure is then valued, using as a reference the literature on the willingness to pay for preventative action.

A Food Demand System Based on Demand for Characteristics: If There is " Curvature" in the Slutsky Matrix, What Do the Curves Look Like and Why?
Provedor de dados: 31
Autores: Bouis,   Howarth E.
A food demand system is proposed, based on demand for energy, variety, and tastes of foods. By specifying utility as an explicit function of these characteristics, the entire matrix of demand elasticities can be derived for n foods and one nonfood from prior specification of just four elasticities, while avoiding any assumption of separability between foods. This framework can explain why poorest groups often are most price-responsive, but also can account for highest price-responsiveness by middle income groups. The system is applied to published food consumption data for urban and rural populations in Pakistan. Elasticities are compared with those obtained in a published Pakistan study applying an almost ideal demand system (AIDS).

Price competitiveness and variability in Egyptian cotton: effects of sectoral and economywide policies
Provedor de dados: 31
Autores: Bautista,   Romeo M.; Gehlhar,   Clemen G.
This paper examines the role of price incentives in the observed decline in cotton production during the 1980s and in the apparent improvement in recent years. The following determinants (in an accounting sense) of the changes in the relative producer price of cotton during 1980-92 are quantified: (1) changes in the foreign price; (2) changes in the real exchange rate; and (3) changes in nominal protection and the marketing margin. An estimated model of the real exchange rate for Egypt is used to provide a further decomposition of the changes in the relative cotton price that isolates the effect of policy-related factors. The comparative effects of sectoral and economywide policies are analyzed based on three alternative policy regimes in terms of the...

RURAL-URBAN DIFFERENCES IN NURSING HOME ACCESS, QUALITY AND COST
Provedor de dados: 31
Autores: Yu,   Wei; Bradford,   Garnett L.
Rural-urban differences in the supply of nursing home services as hypothesized to be jointly affected by competitive and regulatory forces, government policies, and the cost structure. Study findings indicate that rural services are slightly less accessible and lower in quality. A translog cost share function reveals no difference in the operating cost structure of rural and urban homes. Cost shares for nursing care are directly related to the degree of skilled nursing provided by homes. Significant scale economies were not detected for any of the major operating costs.

TECHNICAL EFFICIENCY OF RURAL WATER UTILITIES
Provedor de dados: 31
Autores: Bhattacharyya,   Arunava; Harris,   Thomas R.; Narayanan,   Rangesan; Raffiee,   Kambiz.
Technical efficiency of rural water utilities is determined using frontier production functions. An indirect production function is developed to model the two-step production process of a local government-controlled firm. Data from 26 rural Nevada water utilities are used to estimate inefficiency in terms of firm-specific variables. A multistep estimation procedure is used instead of single-step maximum likelihood estimation. Model selection tests are used to choose the best model. Privately owned utilities are most efficient; self-governing water districts are the least efficient. Municipal governments operate the most and least efficient utilities.

PRICE ADJUSTMENTS IN CHERRY MARKETS
Provedor de dados: 31
Autores: Schotzko,   R. Thomas; Wilson,   Wesley W.
Buyers of cherries trade initially without inspection. Upon receipt, buyers sometimes seek to renegotiate the earlier agreements. Empirical results suggest that changing market conditions, fruit quality, and characteristics of the trading partners significantly affect the probability that a trade is renegotiated.

ALTERNATIVE FLUID MILK PROCUREMENT SYSTEMS FOR FLORIDA DAIRY FARMERS
Provedor de dados: 31
Autores: Nubern,   Christopher A.; Kilmer,   Richard L.
This article evaluates the effects of alternative fluid milk procurement strategies on the aggregate net revenue of Florida cooperative members. They are (1) supplemental milk obtained from import sources, (2) supplemental milk obtained from a supply plant, (3) increased supply as a result of an expanded production area, and (4) supplemental milk obtained through pooling arrangements with regional dairy cooperatives. The final ranking of a scenario appears to be dependent primarily on the total cost of exports within the model. The optimal procurement strategy for Florida cooperatives should concentrate on reducing the quantity of surplus milk.

SOCIAL CAPITAL AND ECONOMIC COOPERATION
Provedor de dados: 31
Autores: Robison,   Lindon J.; Hanson,   Steven D.
The socioeconomic movement is an effort to better explain human behavior by combining insights of economists and sociologists.  This paper contributes to the socioeconomic literature by including the influence of relationships, values, and social bonds in the neoclassical economic model by introducing social capital coefficients.  The usefulness of the resulting social capital model is demonstrated theoretically in a two-firm cooperative model and tested empirically using data from a survey of students who allocate their time between individual and joint projects.

RISK AND MARKET PARTICIPANT BEHAVIOR IN THE U.S. SLAUGHTER-CATTLE MARKET
Provedor de dados: 31
Autores: Feuz,   Dillon M.; Fausti,   Scott W.; Wagner,   John J.
Incomplete information generates uncertainty for market participants in the slaughter-cattle market. Buyer and seller behavior in the presence of that uncertainty is examined. Statistically significant risk premiums are charged by packers when buying slaughter cattle on either a live- or dressed-weight basis compared to buying on a grade-and-yield basis. Pratt-Arrow risk-aversion coefficients are calculated for buyers and these remain constant over all marketing methods. Sellers market cattle under all three marketing methods, suggesting producers’' attitudes toward risk (risk-aversion coefficients) vary.

AN OPTIMAL CONTROL MODEL FOR INTEGRATED WEED MANAGEMENT UNDER HERBICIDE RESISTANCE
Provedor de dados: 31
Autores: Gorddard,   Russell J.; Pannell,   David J.; Hertzler,   Greg.
The presence of weeds which have developed resistance to chemical herbicides is a problem of rapidly growing importance in Australian agriculture. We present an optimal control model of herbicide resistance development in ryegrass, the weed for which resistance is most commonly reported. The model is used to select the optimal combination of chemical and non-chemical control measures taking account of the trade off between short term profits and the long term level of herbicide resistance. Results indicate that given the threat of resistance there are benefits from integrating a combination of chemical and non-chemical control measures. The optimal strategy is found to include a declining herbicide dosage as resistance develops, with compensatory increases...

The results of simulation modelling carried out with GLEAMS on hypothetical scenarios driven by the Reform of Common Agricultural Policy are presented.  The model was set up with data collected in recent research projects to simulate a typical cultivated environment of the Venetian Plain (north east Italy) where field experiments are in progress.  Agro-environmental simulations were conducted over a long period using a 30-year whether record.  First single crops, then entire rotations and finally the whole farm production patterns were simulated, based on the present standard agrotechnologies of the study area and on proposed low input systems.  The alternative farm scenarios were taken from those hypthesised by economists on the basis of the recent Common...

The Urban Poor and the Payday: The Pay of the Day Matters, But So Does the Day of that Pay
Provedor de dados: 31
Autores: Minten,   Bart.
Although it has been shown that the poor are more responsive to food price changes than other people, they still may face higher food prices. Evidence from Zaire shows that there exists a movement within the month in food prices corresponding to changes in food supply and food demand. This movement is caused by increased income and demand at the end ofthe month due to a fixed pay date. This movement is especially harmful for the poor, who buy in small quantities. Using a Benthamite social welfare junction, it is shown that rescheduling the payday for different sectors or splitting up payments in smaller amounts will result in higher social welfare.

This study measures the impacts of use of nutrition information and household socioeconomic characteristics on market participation and amount purchased of whole-fat and low-fat milks in the South. Data are from the 1987-88 Nationwide Food Consumption Survey. The results showed that use of nutrition information had little effect on purchases on the basis of nutritional benefits through health professionals and product packaging are useful tools for the dairy industry to attract market participation.

The horror of genocide and civil war have turned the world's attention to Rwanda over the last year. But before and beyond that conflict, there was hunger and the slow grinding poverty of small holder agriculture meeting with severe land scarcity and degradation. This report is about reversing the spiraling decline of the land and the economy in rural Rwanda. Three things conspire to accelerate this decline: unsustainable land use practices, insufficient non-farm employment, and rapid population growth. We focus on the forces behind productivity decline in Rwandan agriculture. This report examines how erosion, organic input use, soil conservation investments, use of fertilizer and lime, and land use strategies affect productivity. We then examine what...

PRICE INCENTIVES FOR COMMERCIAL FRESH TOMATOES
Provedor de dados: 31
Autores: Bierlen,   Ralph W.; Grunewald,   Orlen C.
Hedonic price models are estimated to determine if there are incentives to supply higher quality tomatoes.  Price premiums are associated with extra-large tomatoes originating from shipping points located closer to consumption points.  Price differences between mature-green and vine-ripe tomatoes are not significant.  Vine-ripe tomatoes are favored by consumers in the summer while mature-green tomatoes are favored the rest of the year.  The U.S. Department of Agriculture should consider changing the present tomato grading system, which is based on shape and smoothness, to include a flavor indicator based on harvest maturity.

Sources of Income Inequality and Poverty in Rural Pakistan
Provedor de dados: 31
Autores: Adams,   Richard H., Jr.; He,   Jane J.
Throughout the developing world, policy makers are interested in devising new strategies for improving income distribution and reducing poverty. In large part, the choice of such strategies depends on an improved understanding of the sources of income inequality. Why do certain types of incomes go to different set of people? And what roles do variables such as education and migration play in improving income distribution and in lifting people out of poverty?   This work attempts to answer these questions for rural Pakistan by analyzing a three-year panel data set collected in collaboration with four research institutes in Pakistan. This extensive series of household interviews enables the authors to examines many dynamic income-related issues that cannot...

INTEGRATION AND BEHAVIOR IN THE U.S. WINTER MARKET FOR FRESH TOMATOES
Provedor de dados: 31
Autores: Jordan,   Kenrick H.; VanSickle,   John J.
Alternative hypotheses of market integration in the U.S. winter market for fresh tomatoes were evaluated using a dynamic model of spatial price adjustment.  The results showed that while Florida and Mexico were integrated in the same market, a price change in one area was not instantaneously reflected in the other.  Lagged effects were important with long-run integration being supported for both Florida and Mexico and short-run integration for Mexico.  However, the information flow, while relatively efficient, was not symmetric.  Florida was found to be dominant in the price formation process with Mexico responding to changes in the Florida price.

On Endogenous Growth: The Implications of Environmental Externalities
Provedor de dados: 31
Autores: Elbasha,   Elamin H.; Roe,   Terry L.
This paper uses an endogenous growth model to examine the interaction between trade, economic growth, and the environment. We find that whether trade enhances or retards growth depends on the relation between factor intensities of exportable, importable, and R&amp;D and the relative abundance of the factor R&amp;D uses more intensively. Depending on the intertemporal elasticity of substitution, the long-run rate of economic growth changes with environmental externalities. Concerns about the environment can explain a significant part of cross-country difference in growth rates. For the empirically reported range of the elasticity of intertemporal substitution, countries which care more about the environment grow faster. The effects of trade on the...

The objective of this paper is to provide a framework of accounting to allow the evaluation and comparison of both conventional and traditional agriculture by accounting for both traditional market transactions and the environmental resources and changes in those resources.  Even if a study estimates the value of the change in the resource inventory, the correction to the farmer's financial condition is not made in an explicit way.  Again, the study by Faeth et al. makes a strong contribution to the need to have such an accounting system for farms.  Farmers should be interested in this information because it is their own backyard where they are working, living and using their own assets.  We start with a brief review of the work done with national accounts...

Autores: Kingwell,   Ross S.
A discrete stochastic programming model of the farming system of the eastern wheatbelt of Western Australia is used to examine the effect of tactical responses and risk aversion on wheat supply. Including within-season tactical changes to wheat areas decreases the own-price elasticity of supply. By contrast, introducing risk aversion has no consistent effect on the own-price elasticity of supply. The implications for supply models are discussed.

Modeling Consumption with Limited Dependent Variables: Applications to Pork and Cheese
Provedor de dados: 31
Autores: Yen,   Steven T.; Jensen,   Helen H.
The double-hurdle and infrequency-of-purchase models are applied to pork and cheese consumption using the 1987-88 Nationwide Food Consumption Survey data. The models are generalized with the inverse hyperbolic sine transformation in the dependent variable, and this transformation results in a more flexible parameterization and error distribution than the untransformed models.  Nonnested LR tests suggest that the IHS double-hurdle model provides better characterization of the data-generating process in household pork consumption than the IHS infrequency-of-purchase model but the elasticities derived from these models are similar.  For household cheese consumption, the two models fit the data equally well.  The IHS double-hurdle model and the IHS...

For African agricultural productivity to improve, governments and donors must invest in programs and policies that will improve the incentives and capacity of farmers to make investments that increase farm productivity and soil fertility while protecting the environment. With rapid population growth, agriculture must rapidly intensity if African farmers are to meet the rapid growth in the demand for food and fiber. Recent case studies demonstrate the incentives and capacity to invest in more intensive cropping technologies have declined during the last decade Good macroeconomic policies are necessary by not sufficient.

EFFECT OF PROPOSED GRAIN STANDARDS ON MARKETING COSTS OF THE U.S. SORGHUM SECTOR: AN INTERREGIONAL TRANSSHIPMENT-PLANT LOCATION MODEL
Provedor de dados: 31
Autores: Ziari,   Houshmand A.; Fuller,   Stephen W.; Grant,   Warren R.; Sutaria,   Vinod.
Recent legislative initiatives call for studies to evaluate costs associated with cleaning U.S. grains to meet more stringent standards. This paper reports on a study which developed a mixed-integer programming model of the U.S. sorghum sector to (1) determine the least-cost geographic location for new cleaning investment at the country, terminal and port elevator stages of the marketing system and (2) measure additional system marketing costs associated with implementing the proposed standards. Results show the least-cost cleaning location to be at country and terminal elevators in excess supply regions. Implementing the proposed standard would increase system costs about 2 percent.

THE POTENTIAL FOR HIGH-VALUE AGRICULTURAL PRODUCTS UNDER THE NORTH AMERICAN FREE TRADE AGREEMENT: THE CASE OF BEEF IN MEXICO AND CANADA
Provedor de dados: 31
Autores: Onianwa,   Okwudili O.
The prospects for U.S. beef products in the advent of a North American Free Trade Agreement were examined using a system-wide approach to import allocation. Results indicate that increases in the standard of living in Mexico and Canada would stimulate increased importation of processed and unprocessed beef products had expenditure elasticities of less than one.

THE EFFECT OF MARKET CONCENTRATION ON LAMB MARKETING MARGINS
Provedor de dados: 31
Autores: Brester,   Gary W.; Musick,   Douglas C.
The national four-firm concentration ratio in the lamb slaughtering and processing industry increased from 55 percent in 1980 to 70 percent in 1992. The effect of increasing lamb packer concentration on lamb marketing margins is examined. A relative price spread (RPS) model for farm-to-wholesale and wholesale-to-retail marketing margins was estimated using three-stage least squares (3SLS). The 3SLS results indicate that increased lamb packer concentration has had relatively small, positive effects on lamb marketing margins.

RECREATIONAL SWIMMING BENEFITS OF NEW HAMPSHIRE LAKE WATER QUALITY POLICIES: AN APPLICATION OF A REPEATED DISCRETE CHOICE MODEL
Provedor de dados: 31
Autores: Needelman,   Michael S.; Kealy,   Mary Jo.
Water pollution control policies generally direct sources (i.e., industry, agriculture) to reduce loadings of certain pollutants.  Thus, evaluating the relative net recreation benefits of policies to improve water quality requires establishing a linkage between the sources, the resultant water quality degradation at the affected water bodies, and, ultimately, the effect on recreation behavior.  This linkage is rarely present in the empirical literature which is, thus, deficient for water pollution control policy assessment purposes.  In this paper, we estimate the relative recreational swimming benefits that may result from controlling point and nonpoint sources of pollution, respectively, in New Hampshire's lakes.  We use a repeated discrete choice...

EVALUATION OF ALTERNATIVE RISK SPECIFICATIONS IN FARM PROGRAMMING MODELS

Autores: Ford,   Stephen A.; Ford,   Beth Pride; Spreen,   Thomas H.
The use of alternative probability density functions to specify risk in farm programming models is explored and compared to a traditional specification using historical data.  A method is described that compares risk efficient crop mixes using stochastic dominance techniques to examine impacts of different risk specifications on farm plans.  Results indicate that a traditional method using historical farm data is as efficient for risk averse producers as two other methods of incorporating risk in farm programming models when evaluated using second degree stochastic dominance.  Stochastic dominance with respect to a function further discriminates among the distributions, indicating that a density function based on the historic forecasting accuracy of the...

Pricing behavior in Philippine Corn Markets: Implications For Market Efficiency
Provedor de dados: 31
Autores: Mendoz,   Meyra Sebello; Rosegrant,   Mark W.
Income-led growth in demand for meat is expected to provide the major stimulus for expansion in the Philippine corn sector. Traditionally eaten as a cheaper carbohydrate substituting for rice by many Filipinos, corn is now increasingly being used to grow corn, which has displaced rice as the most important crop in terms of cultivated area.  In recent years, the Philippine government had vigorously pursued a series of sectoral and economy wide policy reforms to invigorate the corn sector and support the feed requirements of the livestock industry. These reforms include more liberal foreign exchange policies, lifting of control over domestic marketing operations, deregulation of the interisland transportation system, and production- augmenting programs. A...

Bulk Fuel Distribution Costs For Cooperatives in North Dakota
Provedor de dados: 31
Autores: Dahl,   Bruce L.; Cobia,   David W.; Dooley,   Frank J.
Economic-engineering cost data and a simulation model were used to analyze the impact of sales density, size of sales area, sales volume, and equipment configuration on costs of bulk fuel delivery by cooperatives. Fixed costs accounted for the majority of delivery costs regardless of sales density or size of sales area, at least for the relevant range of these variables for North Dakota. Increasing the radius of a sales area from 5 to 50 miles increased average costs only $.02 to $.09/gal. Doubling sales by either doubling the size of the sales area or the sales density reduced average total costs by nearly 50%. Thus, cooperatives with excess delivery capacity could achieve significant savings if they consolidate to operate closer to the capacity of...

Integrating Environmental Protection and North American Free Trade
Provedor de dados: 31
Autores: Emerson,   Peter M.; Nessman,   Alan C.
The North American Free Trade Agreement (NAFTA) represents significant developments in both regional trade liberalisation and environmental protection. Pre-agreement negotiations offered non-government organisations (NGOs) considerable opportunity to reduce areas of potential conflict between these two objectives. The Agreement deals with both boundary problems and common standards without dictating uniformity of standards or impinging greatly on each nation's sovereign control over matters within its own borders. The introduction of this practical strategy into the international trade arena could be the most significant feature of the NAFTA in shaping future regional and international trade negotiations.

RESTRICTING WHEAT IMPORTS FROM CANADA: IMPACT OF PRODUCT DIFFERENTIATION AND U.S. EXPORT POLICY GOALS
Provedor de dados: 31
Autores: Haley,   Stephen L.
Because increasing yearly U.S. imports of Canadian wheat have been a major concern of U.S. wheat interests, a policy restricting Canadian wheat imports may endure for the next few years. However, within the context of product differentiation, placing a restriction on the importation of a product that resembles one which is produced domestically may not benefit domestic producers of the product or the interests of policymakers. This analysis shows for various criteria under which EEP targets and bonus amounts have been chosen, it is unlikely that a restriction on U.S. wheat imports from Canada will have any beneficial effects.

ISSUES IN THE DEVELOPMENT OF AN ESTIMABLE DYNAMIC MODEL OF RECREATION BEHAVIOR
Provedor de dados: 31
Autores: Provencher,   Bill; Bishop,   Richard C.
Static travel cost models have been only partially successful in modeling the sequential aspects of a recreation decision like the decision to fish. In this paper we describe a dynamic structural model of the decision to visit a recreation site. The model is best described as a dynamic multinomial logit model. By virtue of its dynamic nature, the model avoids the problem of the independence of irrelevant alternatives that afflicts static multinomial logit models. Welfare effects of changes in site quality are easily calculated via dynamic programming.

Land, water, and agriculture in Egypt: the economywide impact of policy reform
Provedor de dados: 31
Autores: Robinson,   Sherman; Gehlhar,   Clemen G.
The tax and subsidy system in Egypt in 1986-88 was very distorted, involving large, sectorally variegated, output taxes and subsidies. In agriculture, there were also major input subsidies and no charges for water. In this paper, an ll-sector, computable general equilibrium (CGE) model is used to capture this mix of policies, focusing on land and water use in agriculture and on the links between agriculture and the rest of the economy. The model combines an optimizing, programming model of land and water use in agriculture with a simulation model of the non-agricultural sectors. Empirical results indicate that policies in 1986-88 were biased against agriculture and led to a water-conserving structure of agricultural production. Had Egypt introduced markets...

Valuation of Transferable Delivery Rights for Marketing Cooperatives
Provedor de dados: 31
Autores: Moore,   Charles V.; Noel,   Jay E.
Delivery rights to a cooperative's marketing pool can take on a value independent of the members' equity share under certain conditions. Based on anecdotal information, transferable delivery rights become valuable when the pool is fixed in size (closed), members are protected from exploitation of quasi economic rents, and have an assured "home" for their production. The greater the potential buyers' aversion to risk, the higher the value of the delivery right. The right has additional value if the cooperative generates a premium per unit return due to product differentiation and market power. Cooperatives competing with investor-owned firms in less than purely competitive markets must be able to pay equal net returns to members if they are to survive.

Who Eats Yellow Maize? Preliminary Results of a Survey of Consumer Maize Preferences in Maputo, Mozambique
Provedor de dados: 31
Autores: Tschirley,   David L.; Santos,   Ana Paula.
During April and May, 1994, the questionnaire was completed with the person in each household who was responsible for food purchases. At this time, white maize availability was increasing due to the recent harvest, while yellow maize availability was beginning to decline after a long period of great oversupply and very low prices. The questionnaire included sections on family structure; supply sources of maize grain and meals; purchase behavior for maize grain, maize meals, and rice; two "price games" in which consumers were asked to make choices between products at differing prices; and a series of sections meant to quantify household income, including agricultural production and remittances. This brief paper presents some preliminary results from this...

RECREATIONAL AND AESTHETIC VALUE OF WATER USING HEDONIC PRICE ANALYSIS
Provedor de dados: 31
Autores: Lansford,   Notie H., Jr.; Jones,   Lonnie L.
Historically, water allocation focused on quantities demanded by consumptive uses. As quantity demand grows, efficient allocation among consumptive and nonconsumptive uses becomes more critical. This hedonic approach provides information regarding recreational and aesthetic (RA) value for a central Texas lake. The model indicates several statistically significant RA characteristics of housing; proximity is the most important. Waterfront properties command a premium, but marginal RA price falls rapidly with increasing distance. Marginal RA values are estimated for selected water levels and are found to have a lower marginal price per acre-foot than many agricultural uses.

Political Economy Perspectives on the 1994 Turkish Economic Crisis: A CGE Modeling Analysis

Autores: Yeldan,   A. Erinc.
This paper investigates the role of the deterioration of the Turkish public sector balances in the latter half of the 1980's and the evolution of the economic crisis with the aid of a computable general equilibrium model. The theoretical basis of the model utilized in the paper rests upon the Walrasian and the Structuralist/Keynesian macro foundations. The model recognizes 15 production sectors, 3 socio-economic income groups and a central government; and simulates the production, income distribution, consumption, capital accumulation and foreign trade processes of the national economy within a simultaneous system of algebraic equations. The distinguishing feature of the model is that, it accommodates monopolistic mark-up pricing rules in the industrial...

The Impact on the Australian Lamb Industry of Producing Larger Leaner Lamb
Provedor de dados: 31
Autores: Mullen,   John D.; Alston,   Julian M.
An equilibrium displacement model of the Australian lamb industry was used to estimate the changes in economic surplus to the producers, processors and consumers of lamb from an increase in the proportion of total production meeting the criteria for Elite lamb. This change in the nature of the product has implications for consumer demand and for processing and production costs. Estimates of the expected changes in these demand and supply parameters are presented in the paper. The potential demand shift was estimated to be much larger than the changes in production and processing costs and consequently was most influential in determining the extent of the benefits from the change in technology.

Environmental Taxes: Dead or Alive?
Provedor de dados: 31
Autores: Morgenstern,   Richard D.
Both theory and recent trends suggest some optimism for the future of environment-related taxes. While new research emphasizes the potentially significant distortions created by environmental taxes and appears to undermine the so-called "double dividend" theory, it also suggests that virtually any environmental policy, including regulations, taxes, and tradable permits, can compound existing distortions in the tax system. Currently, direct environmental taxes, such as per-unit charges on emissions, are only in limited use; however, indirect environmental levies, including taxes on fuels, vehicles, beverage containers, and fertilizers, are growing in importance across the OECD nations. Over the period 1990-1993, environmental taxes as a share of total...

This study evaluates the economic feasibility of establishing a packing house for the New Jersey Tomato Council Cooperative Association. Several scenarios were evaluated using a comprehensive firm-level, dynamic, stochastic, multiple-year, capital-budgeting computer model. Results indicate that the packing house would have difficulty sustaining itself if it packed tomatoes only during the three months a year that local tomatoes are produced. Economic performance of the packing house improved, however, when additional tomatoes were repacked from another supplier during the months that tomatoes are not produced in New Jersey.

Consumer Demand for Major Foods in Egypt
Provedor de dados: 31
Autores: Fayyad,   Basem S.; Johnson,   Stanley R.; El-Khishin,   Mohamed.
This study provides information on the structure of the consumer demand for major foods in Egypt. The information is in the form of key parameters for consumer demand systems. The modern theory of consumer behavior is the basis for estimating systems of demand equations. These systems yield estimates of own and cross price elasticities. The Linear Almost Ideal Demand System (LAIDS) model is applied in estimating a system of demand equations for food commodities. A full demand matrix results with a coherent and consistent set of price and expenditure elasticity estimates. Using the estimated own and cross price and expenditure elasticities, food and agricultural policies during the transformation to the market economy can be analyzed. A framework for...

This study evaluates the risk and returns to cattle feeding in Alberta from the application of alternative marketing and pricing strategies. Feedlot finishing of 650 pound calves and 800 pound yearlings is modeled over the years from 1980 to 1993. The results of the study are based on the domestic and US marketing of live cattle using traditional cash marketing, futures contracts, put options, and forward production contracting systems. Use of the Western Domestic Feed Barley contract is also simulated. The results showed that barley price changes produced relatively small return changes compared to feeder and fat cattle price changes. An important source of return risk was found to be basis risk.

The Influence of Fat and Weight on the Price of Lamb in the Homebush Livestock and Wholesale Markets
Provedor de dados: 31
Autores: Mullen,   John D.
An econometric analysis is reported of the relationship between price, and fat cover and weight, in the Homebush livestock and wholesale markets in 1987, 1988 and 1989 using data from the Livestock Market Reporting Service. Implicit prices for changes in weight and fat cover were estimated while accounting for changes in supply and demand conditions for lamb. The analysis lends support to the view that consumer preference for leaner lamb was not being reflected in prices offered for lamb in traditional auction markets.

OPTIMUM NITROGEN USE UNDER GROUNDWATER POLLUTION CONSTRAINTS;  Proceedings of the 4th Minnesota Padova Conference on Food, Agriculture, and the Environment, September 4-10, 1994, Wayzata, MN
Provedor de dados: 31
Autores: Easter,   K. William; Yadav,   Satya N.
In this paper we will try to address two questions.  First, are farmers using the level of nitrogen that would maximize profits, and second, does the profit maximizing level of nitrogen use exceed the social optimum?  In the latter case, we determine the optimal level of nitrogen use for continuous corn when the farmer must try to maintain the groundwater quality level at 10 ppm (the EPA safe drinking water standard).  We conclude with recommendations concerning how to achieve the social optimum level of nitrogen use.

Can Producers Place Valid and Reliable Valuations on Wool Price-Risk Information?
Provedor de dados: 31
Autores: Pluske,   Johanna M.; Fraser,   Rob W.
Using the contingent valuation method farmers in the high rainfall region of Western Australia were asked to value the information that they used to reduce risk associated with wool prices. To ascertain whether these values were both valid and reliable they were combined with additional data collected from the questionnaires and incorporated into profit functions so that farmers' attitudes towards risk could be estimated. These risk attitudes may be deemed reliable and valid providing they correspond to those estimated by other researchers. Results showed that the farmers' risk aversion coefficients were comparable to those estimated in the Australian literature. Therefore it may be argued that these farmers were able to nominate valid and reliable...

Forward Integration by Farmer Cooperatives: Comparative Incentives and Impacts
Provedor de dados: 31
Autores: Royer,   Jeffrey S.; Bhuyan,   Sanjib.
A model of a three-stage vertical market structure consisting of agricultural producers. an assembler, and a processor is developed to analyze the market incentives farmer cooperatives may have for integrating forward into processing activities and to evaluate the comparative impacts of cooperative forward integration on producers and consumers. Although forward integration by cooperatives generally provides benefits to both producers and consumers under fixed-proportions processing technology and constant assembly and processing costs. the existence of an integration incentive appears to depend upon the ability of the cooperative to restrict the raw product output of its producers to optimal levels.

Optimal Herbicide Strategies Given Yield and Quality Impacts of Weeds
Provedor de dados: 31
Autores: Pannell,   David J.
Prices received by Australian wheat farmers have increasingly depended on grain quality, especially protein concentration. This concentration depends on various agronomic and physical factors including weed competition. In this paper a model of weed management in the presence of grain quality premiums is presented. Two types of quality premium are examined: a continuout linear payment schedule and a discontinuous "stepped" schedule with substantial premiums for quality levels above a critical level. The model is applied to an analysis of the impact of protein premiums on optimal management strategies for a particular weed in Western Australia. It is found that the impact of protein premiums on optimal weed management is likely to be very small indeed, even...

Economic Issues in Farm-to-Port Grain Storage, Handling and Transport
Provedor de dados: 31
Autores: Brennan,   Donna C.
In this paper, the literature on the economics of grain distribution systems is reviewed. The emphasis of this review is on farm to port issues and largely excludes port and shipping issues. In the first part of the paper, the discussion centres on the historical institutional environment in Australia, which was heavily regulated. The second part of the paper highlights some of the issues relating to the pricing of central grain distribution services that continue to exist even in the more competitive environment which has emerged in the 1990's. The scope for future agricultural economics research in this area is discussed.

In 1992 the National Oceanic and Atmospheric Administration (NOAA) convened a panel of prominent social scientists to assess the reliability of natural resource damage estimates derived from contingent valuation (CV). The product of the panel's deliberations was a report that laid out a set of recommended guidelines for CV survey design, administration, and data analysis. This paper focuses on one of these guidelines -- the Panel's call for the "temporal averaging" of willingness-to-pay (WTP) responses obtained from CV surveys as one method for increasing their reliability. The panel suggested: "Time dependent measurement noise should be reduced by averaging across independently drawn samples taken at different points in time. A clear and substantial time...

Do Taxes on Large Firms Impede Growth? Evidence from Ghana
Provedor de dados: 31
Autores: Gollin,   Douglas.
Many developing countries pursue policies that treat large and small firms differently. For example, large firms may be subject to a value added tax while small firms are explicitly exempted. Moreover, governments often find it impractical to collect taxes from the smallest enterprises; this may increase the tax burden for larger firms, whose compliance can be enforced. Such policies clearly affect the size distribution of firms. But how great is the impact on macro variables? How large are the resulting inefficiencies? And what are the dynamic effects on capital accumulation and economic growth? This paper uses a dynamic general equilibrium variant of the Lucas (1978) span-of-control model to address such questions. The model is matched to data from the...

WHEAT BUFFER STOCKS AND TRADE IN AN EFFICIENT GLOBAL ECONOMY
Provedor de dados: 31
Autores: Makki,   Shiva S.; Tweeten,   Luther G.; Miranda,   Mario J.
This study assesses storage and trade of wheat in an integrated global economy. Domestic and international linkages are analyzed using a dynamic rational expectations model of the world wheat market. The results of this study demonstrate the importance of endogenizing both storage and trade in studying commodity markets. Results suggest an optimal US buffer stock level of 150 million bushel. Results indicate that past government stockholdings have not followed efficient market outcomes. Private markets likely would perform better in the absence of government market distortions. Results indicate that elimination of the Export Enhancement Program by the US and of export restitution payments by the EU is unlikely to have a major impact on wheat exports from...

Total Factor Productivity and Sources of Long-term Growth in Indian Agriculture
Provedor de dados: 31
Autores: Rosegrant,   Mark W.; Evenson,   Robert E.
This paper assesses total factor productivity (TFP) growth in India, examines the  sources of productivity growth, including public and private investment, and estimates the  rates of return to public investments in agriculture.  The results show that significant TFP  growth in the Indian crops sector was produced by investments -- primarily in research -- but  also in extension, markets, and irrigation.  The high rates of return, particularly to public  agricultural  research  and  extension,  indicate  that  the  Government  of  India  is  not  over  investing in agricultural research and investment, but rather that current levels of public  investment could be profitably expanded.

DOUBLE-HURDLE MODEL WITH BIVARIATE NORMAL ERRORS: AN APPLICATION TO U.S. RICE DEMAND
Provedor de dados: 31
Autores: Gao,   Xiaoming; Wailes,   Eric J.; Cramer,   Gail L.
Per capita rice consumption in the U.S. has doubled over the past decade. The effects of social and demographic variables on the household's rice consumption decisions are analyzed along with income and price variables. A double-hurdle model is used to solve simultaneously the consumer decisions whether to purchase rice and how much. The joint decision hypothesis is tested and accepted. The non-normal distribution of error terms may be responsible for possible bias in the empirical test of the joint decision hypothesis. The hyperbolic sine transformation is used to correct the problem in this study prior to testing the joint decision hypothesis.

This paper considers an application of the differential approach to Japanese demand for beef imports from 1970 to 1993. Results of homothetic demand and negative (significant) own-price elasticities indicate that the Japanese did not discriminate against Australian beef, but the decrease in Australia's trade shares was due to changes in relative prices.

Klieve and MacAulay (1993) (KM) analyse bargaining between the Australian and Japanese Southern Bluefin Tuna (SBT) industries using game theory. The KM model is a Nash equilibrium with symmetrical information, threat functions and a set of biological constraints. When we attempted to include the New Zealand SBT industry as a player in the KM model, we discovered important shortcomings in it. In this comment, we outline three major shortcomings in the KM model and propose an alternative model of a Nash equilibrium for the SBT industry.

CAN WE SAVE TROPICAL FORESTS BY HARVESTING NON-TIMBER PRODUCTS?
Provedor de dados: 31
Autores: Southgate,   Douglas; Coles-Ritchie,   Marc; Salazar-Canelos,   Pablo.
Many people believe that tropical forest conservation strategies for Latin America should focus on extracting non-timber products. However, very little economic research has addressed the activity. This paper presents the results of a study of vegetable ivory, or tagua (Phytelephas aequatorialis), production in western Ecuador. It is one of the largest extractive industries in the hemisphere.  We found that, until recently, households collecting tagua received payments that barely covered the value of their harvest labor.  By contrast, a few firms that slice tagua into disks that are exported to overseas button manufacturers have captured sizable profits.  This concentration of economic returns at the top of the domestic marketing chain has been typical of...

DEMOGRAPHIC AND SOCIOECONOMIC INFLUENCES ON THE IMPORTANCE OF FOOD SAFETY IN FOOD SHOPPING
Provedor de dados: 31
Autores: Lin,   Chung-Tung Jordan.
The perceived importance of food safety is instrumental in the success of consumer information programs to promote public health and to market safer foods.  This paper examines how the belief of a household's main meal planner about the importance of food safety in food shopping is influenced by the person's or the household's demographic and socioeconomic characteristics.  Results suggest food safety is more important to main meal planners who are female, older, more educated, non-working, have at-risk household members (elderly, young children, and pregnant women), or live in the Northeast and the South.  Implications of the results on consumer education are discussed.

The Budgetary and Resource Allocation Effects of Revenue Assurance
Provedor de dados: 31
Autores: Hennessy,   David A.; Babcock,   Bruce A.; Hayes,   Dermot J.
The efficiency of redistribution and the level of government costs of revenue assurance are compared with current farm programs.  The results suggest that a revenue assurance program that uses a fixed base acreage and actual or county average yields to assure whole farm revenues could provide a significant improvement over existing policies.  The result derives in large part because revenue assurance works only when needed and it works on the component of the objective function (revenue) that is of greatest relevance to producers.  Also a fixed base revenue assurance scheme would eliminate resource misallocation costs associated with current programs.  A revenue assurance scheme that guaranteed 100 percent of base revenues would provide almost as much...

The Distributional Impacts of Non-Uniform Pricing Schemes for Cooperatives
Provedor de dados: 31
Autores: Fulton,   Murray E.; Vercammen,   James.
The traditional pricing mechanism examined in the economic literature on cooperatives is uniform (or linear) pricing. The conclusion of the literature is that uniform pricing mechanisms will often give rise to economic inefficiencies. These inefficiencies emerge when the cooperative is operating in a region of either increasing average cost or decreasing average cost. The reason for these inefficiencies is that uniform pricing schemes cannot allocate the profits or losses of a cooperative among its members without distorting the decisions members make. The purpose of this paper is to explore the role of non-uniform pricing in generating efficient outcomes and to examine the distributional effects of simple non-uniform pricing schemes. Although the focus of...

This research examines the success of stabilization policies to control hyperinflation in Bolivia. Money demand functions for the hyperinflation and stabilization periods were econometrically estimated and statistically tested. We conclude that the demand for money in Bolivia changed after stabilization policies were implemented, indicating that the new government's objectives were met. Stabilization policies resulted in real economic growth for Bolivia's economy, including its agricultural sector, where agricultural export shares increased tenfold as stabilization policies corrected overvalued exchange rates.

Wheat acreage responses to expected wheat price and price risk are reversed for program and nonprogram-planted acreage in the northern plains, central plains, southern plains, and U.S. Expected wheat price has a strong negative effect on program-complying wheat acreage. Government support prices have a positive effect on program-complying and program-planted acreage. Price risk has a positive effect on program-complying wheat acreage and a negative effect on nonprogram-planted acreage. Estimated price elasticities are higher than in studies where risk was ignored.

An analytical framework to assess the effects of changing income and socio-demographic distributions on aggregate food demand functions in transitional economies is presented. Ignoring such distributional effects can lead to biased estimates of aggregate demand elasticities. The proposed method is applied to Chinese urban household expenditure survey data. The results indicate that the drastic distributional changes that have occurred in China have had notable effects on estimated demand elasticities for both food and non-food commodity groups.

ULYSSES REVISITED - A CLOSER LOOK AT THE SAFE MINIMUM STANDARD RULE
Provedor de dados: 31
Autores: Rolfe,   John.
The Safe Minimum Standard (SMS) Rule has been developed as a decision rule involving environmental assets, particularly species, that face some risk of extinction. The SMS rule has been presented by Bishop (1978) (1979) and Randall (1991) as a better decision process than the use of cost benefit analysis (CBA). This paper explores the relationship between the SMS rule and CBA. It shows that there is a tandem effect in operation because the use of both rules rely on the same underlying preferences in society. There is potential for the two rules to achieve the same results, and doubt over whether the SMS rule is an independent control over CBA.  Instead, the SMS rule may simply operate as a nagging mechanism for issues of particular interest. Its use can be...

Provedor de dados: 31
Autores: Marquez-Cuyno,   Leah Concepcion.
The following section is a discussion of the importance of the problem of agricultural nonpoint source pollution, the conceptual framework and methods, and the research objectives of this study.  Agricultural nonpoint source pollution is an important environmental concern. Agricultural nonpoint sources have been identified as the major contributors to sediments, nutrients, pathogenic bacteria, and pesticides affecting surface water quality (NRC, 1993). Severe soil degradation from erosion, compaction, or salinization, can damage the productive capacity of the soil and exacerbate water pollution. Sediments from eroded croplands interfere with the use of bodies of water for transportation; reduce the life of dams, locks, reservoirs, and other water...

TECHNICAL EFFICIENCY, MANAGERIAL ABILITY AND FARMER EDUCATION IN GUATEMALAN CORN PRODUCTION: A LATENT VARIABLE ANALYSIS
Provedor de dados: 31
Autores: Kalaitzandonakes,   Nicholas G.; Dunn,   Elizabeth G.
In this study it is argued that conflicting empirical results on the relationship between technical efficiency and education may be in part attributed to difficulties in the measurement of key variables.  Calculation of technical efficiency with three alternative frontier methods for a sample of Guatemalan corn farms resulted in significant differences both in the average technical efficiency of the sample and the efficiency rankings of individual farms.  Furthermore, following two-step procedures where technical efficiency is regressed against a set of explanatory variables, it is shown that the choice of efficiency measurement technique can alter the importance of education as a contributing factor to increased technical efficiency.  An alternative...

THE FEASIBILITY OF POULTRY LITTER TRANSPORTATION FROM ENVIRONMENTALLY SENSITIVE AREAS TO DELTA ROW CROP PRODUCTION
Provedor de dados: 31
Autores: Govindasamy,   Ramu; Cochran,   Mark J.
Arkansas ranks first in broiler production in the USA with more than a billion broiler and 1.5 million tons of litter produced in 1993.  Transporting litter from western to eastern Arkansas can accomplish two goals: 1) avoid potential threat to clean water in western Arkansas and 2) can increase productivity of graded lands in the Delta.  This paper examines the feasibility of litter transport from areas of high poultry concentrations to the Delta for use as a soil amendment.  We establish the conditions for economical litter transport from source to destinations and determine the optimal rates of litter applications.  The results suggest that it is economical to transport significant portions of litter.

Autores: Darwin,   Roy; Tsigas,   Marinos E.; Lewandrowski,   Jan; Raneses,   Anton.
Recent studies suggest that possible global increases in temperature and changes in precipitation patterns during the next century will affect world agriculture. Because of the ability of farmers to adapt , however, these changes are not likely to imperil world food production. Nevertheless, world production of all goods and services may decline, if climate change is severe enough or if cropland expansion is hindered. Impacts are not equally distributed around the world.

This report analyzes the effects of grain market reform and food subsidy elimination in Eastern and Southern Africa on access to food for low-income consumers. The report also assesses the potential to use "self-targeted commodities" to improve vulnerable groups access to food though market development strategies and food aid programs. While much research has been devoted to understanding how producers and traders would respond to reform of staple food markets, relatively little is known about the potential or actual responses by consumers. The report presents recent findings from six household-level surveys in urban areas of Zimbabwe, Kenya, Zambia, and Mozambique between 1991 and 1994. Secondary data from South Africa and Malawi are also presented where...

A PRINCIPAL-AGENT MODEL FOR REGIONAL PEST CONTROL ADOPTION
Provedor de dados: 31
Autores: Ahouissoussi,   Nicolas B.C.
Investigating the underlying producer characteristics associated with regional pest control adoption revealed an interesting proposition. Early adopting producers of firm-specific techniques with characteristics including higher education, more specialized operations, and larger sized business units are dissatisfied with a regional pest control technique. This study provides an explanation of the proposition based on a principal-agent model. Empirical support for the proposition is also presented by developing a multinomial logit model for predicting producers' dissatisfaction with boll weevil eradication.

REGIONAL DIFFERENCES IN THE CONTRIBUTION OF OFF-FARM WORK TO INCOME INEQUALITY
Provedor de dados: 31
Autores: El-Osta,   Hisham S.; Bernat,   G. Andrew, Jr.; Ahearn,   Mary Clare.
This paper uses the concept of the Gini Coefficient and data from the 1991 Farm Costs and Returns Survey (FCRS) to measure the role of off-farm income and that of other income sources in the size distribution of farm operator households' total personal income.  Disaggregated FCRS data by region and by level of participation in off-farm employment show that nonparticipating farm operator households have, as a group, higher income inequality than participating households.  The results also indicate that, irrespective of the off-farm work status of the farm operator household, the distribution of income among households in the North Central region is least unequal and that in the West is most unequal.

RURAL-TO-URBAN WATER TRANSFERS: MEASURING DIRECT FOREGONE BENEFITS OF IRRIGATION WATER UNDER UNCERTAIN WATER SUPPLIES
Provedor de dados: 31
Autores: Taylor,   R. Garth; Young,   Robert A.
Irrigation water from a southeastern Colorado county has been sold to distant municipalities. The county's junior water right delivered limited and uncertain water supplies which were used on relatively poor soils. The ability of water markets to allocate water to the highest-valued use was addressed by assessing the direct foregone benefits of the transfer using deterministic and discrete stochastic sequential (DSSP) programming models. Crop mix predicted by the DSSP followed observed regional patterns. The DSSP was thus used to derive regional water demand from which foregone value was estimated.  Direct regional foregone agricultural benefits were relatively low-due to uncertain water supplies and unproductive soils-indicating the market selected a...

MODELING ECONOMIC GROWTH WITH UNPREDICTABLE SHOCKS: A STATE-LEVEL APPLICATION FOR 1960-90
Provedor de dados: 31
Autores: Goetz,   Stephan J.; Ready,   Richard C.
A Barro-type economic growth model is estimated for the 50 states in the U.S. using data for three decades beginning in 1960. Frontier estimation techniques are used to test for the presence of state-specific shocks to economic growth that are independent of the usual, normally-distributed random errors. We find that large, positive shocks to growth occur during the period 1960-90. Our results indicate that the error term structure assumed each other OLS may not be appropriate for modeling economic growth.

Designing Policy Research on Local Organizations in Natural Resource Management
Provedor de dados: 31
Autores: Scherr,   Sara J.; Buck,   Louise; Meinzen-Dick,   Ruth Suseela; Jackson,   Lee Ann.
As policy research on natural resource management (NRM) evolves, new priorities are emerging related to the strategy, design and implementation of policies to support local organizations (LOs) as managers of natural resources. However, research on policies affecting LOs is at a very early stage, with no accepted body of indicators, methodologies and conceptual approaches, and little documentation or critique of the research methods that have been used. To address this gap, and to lay the basis for a future program of comparative research, IFPRI, CIFOR and ODI co-sponsored an international workshop in October 1994, with experts from different disciplines and different resource domains. This synthesis paper highlights and further explores the discussions and...

Period Equity and Tax Averaging Schemes
Provedor de dados: 31
Autores: Moon,   Lynelle; Peterson,   Deborah C.; Kokic,   Philip; Douglas,   Robert A.
The tax differential caused by variability of taxable income across tax thresholds is estimated for broadacre family farmers using individual taxable income data. Estimates of the tax differential without income averaging are compared with the tax differential under a number of alternative averaging schemes, including the current averaging scheme, modified averaging, block averaging and carry forward tax credits. Only limited evidence is available to indicate the potential tax differential borne by non-primary producers. The availability of such information would assist future analysis of comparative period inequity of farmers and others in the community subject to variable pre-tax incomes.

This article considers the political, economic, and environmental factors associated with the allocation of federal LISA (Low Input/Sustainable Agriculture) funds among states.  A tobit model is estimated with LISA allocations as the dependent variable.  Results indicate that pressure groups are important.  LISA funding depends positively on membership in environmental organizations, the number of farms, and the size of the rural-nonfarm population, while it depends negatively on the size of the urban population.  States with host LISA institutions receive significantly more funding, as do states with Senators in leadership positions on key congressional agricultural committees.

The Economics of a Regulated Dairy Market: An Empirical Analysis of Factors Determining the Values of Fluid Milk Quota
Provedor de dados: 31
Autores: Veeman,   Michele M.; Dong,   Xiao-Yuan.
Based on the hypothesis that tradeable marketing quotas may be analysed as an economic input in the production process of regulated firms, the standard capital asset pricing model is adapted to assess the impact of expectations of quota rents on Ontario fluid milk quota values. The analysis provides estimates of the marginal impacts on quota values of two variables postulated to proxy the rent that arises from the highly regulated market for this product. The results are consistent with expectations from economic theory for a divisible capital asset. It appears that the regulated marketing system for fluid milk has enabled appreciable returns from improvements in milk production technology and administered prices to be appropriated by producers.

Quality-Equivalent and Cost Adjusted Measurement of International Competitiveness In Japanese Rice Markets
Provedor de dados: 31
Autores: Ito,   Shoichi; Rosegrant,   Mark W.; Agcaoili-Sombilla,   Mercedita C.
In this research, the quality of foreign japonica rices was evaluated in terms of prices relative  to  Japanese  domestic  retail  prices.    Then,  retail  prices,  consumer  benefit,  and  competitiveness among the foreign rices in the Japanese market were estimated assuming  those  rices  were  imported  at  prices  based  on  their  production  and  transportation  costs.   According to the results, rices produced in China are quite superior to rices grown in the  United States.  Further, a 700 percent of tariff, which was discussed in the GATT negotiation  and assumed to be imposed on rices imported to Japan, appears to be too low for Chinese  rices and too high for American rices.

Measures of Buyer Concentration in the Australian Wool Market
Provedor de dados: 31
Autores: Hanson,   Phillip; Simmons,   Phil.
The study uses empirical measures of market concentration to examine buyer competition in wool between 1974 and 1992.  Three measures of concentration are examined, concentration ratios, Herfindahl indices and Lorenz curves. Data from the Australian Council of Wool Exporters are used to obtain estimates of these measures over the sample period. The results indicate that the buying sector in the Australian wool market is relatively concentrated and calculation of Spearman correlation coefficients indicate that rankings have not altered significantly in recent years.

EFFECTIVENESS OF USE-VALUE ASSESSMENT IN PRESERVING FARMLAND: A SEARCH-THEORETIC APPROACH
Provedor de dados: 31
Autores: Tavernier,   Edmund M.; Li,   Farong.
Search theory is used to present a theoretically defensible model to examine the effectiveness of use value assessment (UVA) in preserving farmland. The model is empirically tractable and supports the findings of past research. The analysis considers the impact of farm income, uncertainty, and the distribution of the offer price on the effectiveness of UVA in preserving farmland and shows, through the effect on the reservation price, that for a given distribution of the offer price, property-tax rate, and the difference between market-value and use-value of land, the preservation of agricultural land only takes place within a relevant range.

This paper is concerned with the evolution of the agricultural system and its consequences for the international research.  In particular, the gradual liberalization of international markets, the changing in consumer’s preferences in western countries, the increasing in concentration in food distribution and industry, and the economic and demographic problems of developing countries are affecting the demand and supply of agricultural and food products.  Consequently, also the agricultural research has to follow or, even better, to anticipate the changings in order to answer to the different and new demand of technology and information.

Autores: Araji,   A.A.; White,   Fred C.; Guenthner,   Joseph F.
Returns to investments in potato research were estimated for the United States and six subregions. The study combines time-series and cross-sectional data to estimate the supply response for potatoes. Two research variables, research within the state and within the region, were included as exogenous variables to identify spillovers of research results.  The rate of return to investments in potato research in the U.S. is estimated at 79%. Of this, 31% accrues to states conducting the research and 69% is accounted for by the spillover effects.

PESTICIDE PRODUCTIVITY: WHAT ARE THE TRENDS?
Provedor de dados: 31
Autores: Teague,   Mark L.; Brorsen,   B. Wade.
Obtaining estimates of pesticides productivity is an economic response to the growing public concern about the steady increase of pesticide use in the United States. This type of research indicates the cost of limiting pesticide use in terms of foregone output. Pervious empirical studies give a "snap-shot", or "average", look at pesticide productivity. This research effort employs a random coefficient model to determine the trend of the marginal value product of pesticides in agriculture in the United States. Results show a distinct downward trend in two states, Iowa and Texas. California, however, shows no evidence of a downward trend.

RESPONDENTS TO CONTINGENT VALUATION SURVEYS: CONSUMERS OR CITIZENS?
Provedor de dados: 31
Autores: Blamey,   Russell K.; Common,   Mick S.; Quiggin,   John C.
The fundamental assumption of the contingent valuation method (CYM) is that responses to CY questionnaires may be interpreted as expressions of consumer preferences. The consumer preference interpretation has been challenged in recent papers arguing that willingness to pay for wildlife preservation is generated, at least in part, by ethical concerns, rather than by a view that wildlife preservation will yield any benefit to individual respondents. Some further evidence bearing upon these questions is derived from a study of forest management in Australia undertaken by the Resource Assessment Commission (RAC). The evidence supports the interpretation that respondents are acting primarily as citizens.

OBLIGATIONS AND PENALTIES UNDER LEMON LAWS: AUTOMOBILES VERSUS TRACTORS
Provedor de dados: 31
Autores: Centner,   Terence J.; Wetzstein,   Michael E.
Distinctive new provisions of tractor lemon laws which create obligations and provide penalties for defective self-propelled agricultural equipment are contrasted with provisions of automobile lemon laws. Lemon-law obligations involve both producers'’ guarantees to provide consumers with a serviceable vehicle and producers'’ promise to remedy defects. Due to fewer manufacturer obligations under the tractor lemon laws as opposed to automobile lemon laws, tractors may be expected to have more defects than automobiles. Yet the tractor lemon laws contain fewer penalties in the form of restitution remedies. The inconsistencies of these obligations and penalties suggest tractor laws may be inefficient.

THE INFLUENCE OF THE LOCAL ECONOMY AND THE WILLINGNESS TO MOVE ON HUMAN CAPITAL ACCUMULATION IN CENTRAL APPALACHIA
Provedor de dados: 31
Autores: Broomhall,   David.
This study uses logit analysis to examine the influence of the perception of local economic opportunities and the willingness to move on the educational aspirations of rural high-school-aged youths. Those youths who are more willing to move have a greater career opportunity set and a string incentive to achieve in school, since education allows them to compete for jobs elsewhere. A low willingness to move, coupled with a low perception of local job opportunities, translates into a low expected return to education, which reduces the incentive to achieve in school.

The reform of the Common Agricultural Policy (CAP) adopted on 21 May 1992, to be implemented by 1996, anticipates some essential features of the 1994 Uruguay GATT Agreement to be implemented between 1995 and 2000.  Together these two events will change substantially, and sometimes reverse, the past trends in the EU agricultural policy, and generate unprecedented changes in production, trade, as well as in producers’ and consumers’ welfare, creating conditions for a more timely structural adjustment.  This paper will first outline the new scenario of agricultural policy in the EU in order to better devise its likely impact on the economy, namely on income distribution, on resource allocation and on the natural and social environment.

The Role of Income Taxation in Natural Resources Management
Provedor de dados: 31
Autores: Davenport,   Scott V.
It is widely accepted that accelerated depreciation concessions, such as sections 75B and 750, are a poor means for government to address environmental objectives. This position is further supported by recent information highlighting the limited behavioural effect of this form of intervention. The continued existence of poorly targeted subsidy measures, in the face of mounting evidence of their ineffectual nature, suggests they are an important source of political benefits. It is further proposed that as assistance to agriculture declines, the political value of 'generic' policies providing economic rents to industry, such as taxation concessions, will increase and potentially impede the development of agricultural-environmental policy.  The further point...

The paper computes income- and expenditure-based poverty measures and investigates their sensitivity to the use of per capita and per adult equivalent units. It also tests for differences in poverty incidence between individuals in male- and female-headed households using stochastic dominance analysis. Stochastic dominance analysis reveals that differences between male- and female-headed households among the very poor are not sufficiently large that one can conclude that one is unambiguously worse- or better-off, except for a few exceptions. When we use the method of endogenous bounds, persons in...

USING ECONOMIC INCENTIVES TO CONTROL POLLUTION IN RUSSIA
Provedor de dados: 31
Autores: Golub,   Alexander; Kolstad,   Charles D.
This paper investigates Russia's system of environmental management, especially economic tools used to control pollution.  It also describes the Russian experience with a system of pollution fees.  In particular, we consider how the system of pollution fees works, how fee levels are set, the incentive properties of the fees, and the ultimate use to the Russian government of the revenue from the emission fees.  Although the emission fees are quite substantial for some pollutants, the incentive properties of the fees are almost nonexistent.  The primary purpose of pollution fees is to generate funds for state-owned enterprises to invest in pollution abatement equipment.  This is substantially different from the operation of a pollution fee in the West.

Economic Comparisons of Alternative and Conventional Production Technologies for Eggplant in Southern Georgia
Provedor de dados: 31
Autores: Brunson,   Kathryn E.; Stark,   C. Robert, Jr.; Wetzstein,   Michael E.; Phatak,   Sharad C.
Environmental concerns about pesticide usage in traditional production systems are prompting vegetable producers to consider alternative systems. Research results from a multi-year study on eggplant in southern Georgia compare two alternative production technologies to the conventional rye cover crop technology. Alternative technologies utilize beneficial insect principles as substitutes for conventional pesticide controls. Using field data, eggplant production budgets are developed to generate net return estimates under each system. Cost reductions achieved by using alternative technologies are not sufficient to offset the reduced yields and returns generated from these technologies. Cash input requirements for alternative systems suggest potential for...

Estimation of the Usual Intake Distributions of Ratios of Dietary Components
Provedor de dados: 31
Autores: Carriquiry,   Alicia L.; Fuller,   Wayne A.; Goyeneche,   J.J.; Dodd,   Kevin W.
In recent years, it has become apparent that ratios of usual intakes of dietary components, such as the percent of calories from fat or the percent of calories from standard fat, are important indicators of dietary adequacy.  The problem of estimating a percentile of the distribution of ratios of usual intakes of nutrients presents problems that arise from the fact that, from a statistical point of view, ratios of dietary components can be viewed as ratios of random variables.  The methods developed by Nusser et al. (1995) to estimate usual intake distributions of nutrient, for example, cannot be directly applied to ratios, since the ratio of usual intakes is not equal to the mean of the ratio of daily intakes.  In this paper we discuss the problem of...

IMPACTS OF EGYPTIAN SOCIO-ECONOMIC ENVIRONMENT ON DIETARY PATTERN AND ADEQUACY
Provedor de dados: 31
Autores: Soliman,   Ibrahim; Eid,   Nafissa.
Health and nutrition status including dietary adequacy are basic components of the human development and indicators for welfare in a certain community. The study focused upon how far a socio-economic environment would affect the dietary pattern and adequacy in Egypt. The current dietary pattern was compared with that before the economic reform adjustment, i.e. before 1986. Dietary adequacy of energy and protein was assessed to define the poverty line among urban and rural populations. The investigated changes in the socio-economic environment were income level, distribution, growth and price level by region; as well as demographic features of the household. Finally, the study discussed policy implications on both micro and macro level and provided...

Using a maximum entropy technique, we estimate the market shares of each firm in an industry using the available government summary statistics such as the four-firm concentration ratio (C4) and the Herfindahl-Hirschmann Index (HHI).  We show that our technique is very effective in estimating the distribution of market shares in 20 industries. Our results provide support for the recent practice of using HHI rather than C4 as the key explanatory variable in many market power studies, if only one measure is to be used.

Autores: Chen,   Jin.
This paper reviews recent empirical research on measures of industrial performance in world trade.  Two recently developed indices, comparative advantage and competitive advantage, are used to analyze trade patterns of major rice exporting countries in the world rice market.  The empirical test results conclude that there is no significant difference between revealed comparative advantage and revealed competitive advantage for the five major rice exporters.  The ranking for the five exporters based on test results suggest that Burma has the greatest comparative advantage and competitive advantage in exporting rice, Thailand and Pakistan rank second, and the United States and China rank third among the five major exporters.

THE STRUCTURE OF FARMERS' PERCEPTIONS OF GROUND WATER POLLUTION
Provedor de dados: 31
Autores: Elnagheeb,   Abdelmoneim H.; Jordan,   Jeffrey L.; Humphrey,   Vonda.
Data from a 1992 Georgia Farm Practices survey are used to examine the structure of farmers' perceptions of ground water pollution and their support of regulations to protect ground water. Estimates of the influence of farm and farmer characteristics on pollution perceptions and support for pollution control were computed using a multiple-indicator model. Results show that the willingness to change farm practices to protect ground water is positively related to how an operator perceives the seriousness of the pollution problem. Regulatory policies that negatively affect farmers' income are likely to be opposed by farmers.

SPATIAL EQUILIBRIUM WITH INTERMEDIATE PRODUCTS:  IMPLEMENTATION AND VALIDATION IN THE MERCOSUR
Provedor de dados: 31
Autores: Waquil,   Paulo Dabdab; Cox,   Thomas L.
This paper develops the formulation of a spatial equilibrium model with intermediate products. The presence of intermediate products brings a better representation of the real world, accounting for the technological relationships among commodities in the several stages of production. Instead of the usual assumption of constant costs of transformation, positively sloped cost of transformation functions are assumed, reflecting increasing marginal costs of transformation. The model is implemented and validated in the analysis of the optimal allocation and pricing of animal products, grains and oilseeds in the MERCOSUR.

MARKET CONDUCT UNDER GOVERNMENT PRICE INTERVENTION IN THE U.S. DAIRY INDUSTRY
Provedor de dados: 31
Autores: Liu,   Donald J.; Sun,   Chin-Hwa; Kaiser,   Harry M.
The degree of market power exercised by fluid and manufactured processors in the U.S. dairy industry is estimated. Appelbaum’'s quantity-setting conjectural variation approach is cast into a switching regime framework to account for the two market regimes created by the existence of the dairy price support program: (a) government supported regime (market price is at the support price) and (b) market equilibrium regime (market price is above the support price). The model is also used to test whether government price intervention has a pro-competitive to anti-competitive influence on market conduct.

An Analysis of Alternative Maize Marketing Policies in South Africa
Provedor de dados: 31
Autores: Jayne,   Thomas S.; Hajek,   Milan; van Zyl,   Johan.
The maize-oriented agricultural economies throughout Southern Africa are in fundamental transition. Increased recognition of the costs of historical controls on pricing and marketing already has led to partial maize market liberalization in several countries in the region. However, there is still intense debate over the appropriate scope and implementation of future food market reform. Much of the debate derives from uncertainty over the consequences of comprehensive and politically risky changes to domestic markets, especially at a time when regional market conditions are also in flux due to agricultural restructuring in neighboring countries. There is currently little information on the direction and magnitude of grain trade between South Africa,...

The purpose of this study was to determine whether there is a statistical difference in sales responsiveness to advertising among whole, lowfat, and skim milk consumers. A case study for New York City which used monthly time series demand data from 1986 through 1992 is presented. Separate per capita demand functions were estimated for whole, lowfat, and skim milk when per capita generic fluid milk advertising expenditure was used as one of the explanatory variables. Other explanatory variables of per capita sales included retail prices of whole, lowfat, and skim milk, retail price of orange juice, per capita income, and a health index representing consumer concerns about fat in one's diet. Long run sales responsiveness to generic milk advertising were...

The Role of Taxation in the Prevention and Treatment of Land Degradation
Provedor de dados: 31
Autores: Peterson,   Deborah C.
Tax provisions for land care are often justified as corrections for externalities. It is argued in this paper that land care provisions can be justified independently of an externality correction objective, since land care provisions can be viewed as a partial correction of the failure of the depreciation provisions in the Income Tax Assessment Act 1936 to recognise that items other than plant and articles devalue through use. This argument only applies to depreciation over the effective life of the asset and not to the provision of accelerated depreciation. There may be a role for Pigouvian subsidies in the case of land degradation to address the externality problem, and some degree of accelerated depreciation may be viewed as an approximation of such. It...

Autores: Perali,   Carlo Federico; Cox,   Thomas L.
This study examines some of the issues that are often encountered when analysing the socio-economic information of expenditure surveys using the Colombian 1985 urban expenditure survey as an example. This study discusses the problem of estimating prices when only information on expenditures and demographic characteristics is available, the options available when aggregating commodities and defining demographic or labour information, and the advantages and drawbacks in choosing total expenditure as a proxy for income or as the metric for poverty measurement. The study also applies non-parametric density estimation as a form of exploratory data analysis and as a means to learn from the data about the most proper parametric specification.

Quebec, Ontario and the Northeast U.S. are expected to be important players in Canada-U.S. dairy trade. This study explores two dairy trade scenarios between Quebec, Ontario and the Northeast U.S. In simulation I, the U.S. is allowed to unilaterally export yogurt and frozen desserts to Canada, and simulation II reflects a total free trade environment. In both trade simulations, the Canadian farm milk value decreases significantly.

Retroactive Liability and Future Risk: The Optimal Regulation of Underground Storage Tanks
Provedor de dados: 31
Autores: Boyd,   James; Kunreuther,   Howard.
The optimal design of environmental liability policy focuses on two primary policy issues: the cleanup of existing sources of pollution and the definition and enforcement of policies to promote prospectively efficient environmental risk reduction. Through the analysis of a policy toward a pervasive environmental risk -- leaking underground storage tanks - we analyze the effectiveness of an existing policy governing retroactive and prospective liability issues and suggest ways in which that policy can be improved. While we find some theoretical support for the public financing of UST cleanups, we also find the current system to be flawed in its implementation. In general, the paper argues that public financing of past pollution cleanup costs can lead to...

Natural resource prices: will they ever turn up?
Provedor de dados: 31
Autores: Berck,   Peter; Roberts,   Michael J.
Hotelling's theory predicts that natural resource rents should increase over time. However, technical progress in resource extraction, environmental constraints, or great natural abundance could result in stagnant or declining product prices. Thus, there is no theoretical reason to believe that product prices will rise in the near future. The prediction of product prices by time-series methods is shown to depend critically upon whether the series are modeled as differenced or trend stationary. Dickey-Fuller and Lagrange Multiplier tests are used to show that the series are differenced stationary. Long- and short-sample series are tested. Trend-stationary modeling strongly predicts rising resource prices. The result from differenced-stationary modeling is...

Market Development and Food Demand in Rural China
Provedor de dados: 31
Autores: Huang,   Jikun; Rozelle,   Scott.
This paper seeks to understand how market imperfections affect the behavior of consumers in China's rural economy. A theoretical and empirical model is developed and estimated using a household-level data from six counties in Hebei Province. The results show that market development plays an important role in explaining food consumption behavior in China. As the market develops, farmers demand less grain and vegetables and consume more meat, fruit, and other food products after control for income and price effects. Moreover, the elasticities of demand also change as farm households begin to rely more on rural markets. The results of this paper suggest that a government concerned about the welfare of its rural population may want to be paying a more active...

Determinants of Household Expenditures on Alcohol
Provedor de dados: 31
Autores: Yen,   Steven T.; Jensen,   Helen H.
This paper examines the determinants of household alcohol expenditures by using a nonnormal and heteroscedastic double-hurdle model to accommodate zero observations in the sample. The model is a generalization of the double-hurdle model estimated in previous studies of alcohol consumption. We also examine the effects of explanatory variables by calculating and decomposing the elasticities. Findings support the use of a more generalized error distribution. Income, region, education, and household demographics are among the significant determinants of alcohol expenditures.

Rural Income Tax Reform: The New Zealand Experience 1985-1994
Provedor de dados: 31
Autores: King,   John M.
This paper outlines the New Zealand experience in reforming primary sector income tax regimes in 1987 and the subsequent review in the 1991-93 period. The reforms were undertaken to remove tax concessions to primary producers, and to thereby improve tax neutrality with other sectors. This was achieved, but not without considerable opposition and resistance from the industry. The reforms, the processes of development and implementation together with the industry reaction are discussed with a minimum of technical detail.

RECENT DEVELOPMENTS OF THE EU FARMLAND MARKETS: NATIONAL VARIABLES AND COMPARATIVE EFFECTS OF THE CAP REFORM IN SELECTED COUNTRIES; Proceedings of the Fourth Minnesota Padova Conference on Food ,Agriculture, and the Environment, September 4-10, 1994, MN
Provedor de dados: 31
Autores: Bazzani,   Guido Maria; Canavari,   Maurizio; Grillenzoni,   Maurizio; Ragazzoni,   Alessandro.
The present paper consists of two main parts. The first one gives a picture of the more recent development of the farmland market in selected EC countries since 1985/86.  Two main indicators are used to make relatively comparable the observed trends concerning: i) land mobility, ii) farmland values.   The second one tries to evaluate the effects of the CAP reform and the influence of national variables overtime, taking into account the following indicators: i) mobility (on land transfers; on tenancy), ii) income (for agricultural or forest use), iii) farmland values (in the plain; in the hill/mountain areas). Considerations on land market complexity and segmentation are finally included, with justification on the empirical approach adopted in the paper.

The Green Industry Today - Some Issues and Future Prospects
Provedor de dados: 31
Autores: Johnson,   Doyle C.; Christensen,   Robert L.
Green industry sales are projected to total $40.4 billion in 1994. The industry ranked sixth in 1991 among farm commodity groups in total cash receipts, and over the past decade total receipts increased 10 percent per year. Net income per farm is the highest of all the commodity groups. Nevertheless, the sector has received scant federal support compared to other commodities. In spite of growth and significance, economic analysis and data availability and reliability have been limited. There is clear justification for increased efforts in data collection and economic analysis of this industry’s problems.

METHOD TO ESTIMATE PESTICIDE USED IN AGRICULTURE AND GROUNDWATER IMPACT POTENTIAL IN MICHIGAN
Provedor de dados: 31
Autores: Yen,   Yi-Yu.
Pesticide contamination of groundwater has been linked to intensive agricultural activity. Several federal legislations have been applied to protect groundwater quality from on-farm pesticide contamination, but results have not been notable. The environmental protection agency has mandated that states develop management plans based on area-specific differences in groundwater use, value, and vulnerability. The Michigan Department of Agriculture (MDA) has been structuring its programs based on a combination of aquifer sensitivity and groundwater impact potential; and attempting to estimate aquifer sensitivity based on soil type and sub-surface geology. This paper is to define the method to estimated total mass of "likely to leach" pesticides applied in each...

THE ECONOMICS OF CONVERTING CONVENTIONALLY MANAGED EASTERN VINEYARDS TO ORGANIC MANAGEMENT PRACTICES
Provedor de dados: 31
Autores: White,   Gerald B.
A five-year study was conducted to analyze the economic results of growing grapes using conventional management practices compared with organic management practices. Grape cultivars evaluated in the project were Concord, Elvira, and Seyval. Growing costs were higher for each cultivar in each season, Le. for 15 comparisons for the organic system. Operations which were especially costly in the organic system were fertilization, tillage operations which replaced herbicides used in the conventional system, and hand hoeing which was occasionally necessary to supplement weed control in the organic system. The organic system, however, had a clear advantage in most seasons in the cost of spraying operations. The results of this five-year study suggest that grapes...

The interface between RS-CRAM and the environmental component of the integrated modeling system is described for crops, crop sequences, and management systems representative of western Canada.  An experimentally designed set of EPIC simulations were performed to generate erosion output that was used to construct wind and water erosion metamodels (response functions).  The results of the EPIC simulations indicate that wind and water erosion would be the dominant erosion problem over most of Saskatchewan and Manitoba.  For Alberta, water erosion was predicted to be the dominant problem, except for the southern portion of the province.  Erosion impacts were sensitive to tillage and cropping patterns.  EPIC-predicted yields did not vary much across tillage, a...

DOES TECHNICAL PROGRESS IN AGRICULTURE ALLEVIATE POVERTY? A PHILIPPINE CASE STUDY
Provedor de dados: 31
Autores: Coxhead,   Ian A.; Warr,   Peter G.
We examine the impact of technical progress in agriculture on changes in measured poverty and aggregate welfare in a developing country. Using a small general equilibrium model, we show how the economic components of an observed change in poverty can be isolated to expose the significance of intersectoral linkages and the economic roles of changes in relative commodity and factor prices. Variation in the measured rate and distribution of poverty alleviation depends somewhat on the choice of poverty measure, but more substantively on structural assumptions and the effects of policy interventions in agricultural markets.

Research on the transition to a new world economic order has already produced rich empirical results which help to validate sixteen specific research hypotheses for socialist and capitalist, underdeveloped and developed contexts, as well as the world economy as a whole. This multi-disciplinary literature on the NWO also maps out appropriate strategies that nations could follow to reach the goals of international efficiency, equity, equilibrium and positive evolution. Because of remaining lacunae and occasional disagreement, further research on the natural environment, economic motivation, social structures, political institutions, unifying values, and modeling techniques must be pursued.

Depreciation erodes the Coase Conjecture
Provedor de dados: 31
Autores: Karp,   Larry S.
If a durable good monopolist produces at constant marginal costs and the good depreciates, there exists a family of Strong Markov Perfect Equilibrium (SMPE) with an infinitesimal period of commitment. One member of this family entails instantaneous production of the level of stock produced in a competitive equilibrium; this is consistent with the Coase Conjecture. Other SMPE in the family entail steady state production at a stock level lower than in the competitive equilibrium. In these equilibria, there may be a jump to the steady state, or the steady state may be approached asymptotically. Monopoly profits are positive in these equilibria, and the Coase Conjecture fails. We contrast this result to other papers which use non-Markov strategies to construct...

TRADE-OFF ANALYSIS OF HERBICIDE WITHDRAWALS ON AGRICULTURAL PRODUCTION AND GROUNDWATER QUALITY
Provedor de dados: 31
Autores: Liu,   Shiping; Carlson,   Gerald A.; Hoag,   Dana L.
This study examines the trade-off between agricultural production and groundwater contamination potential for ten potential herbicide cancellations. Theoretical and empirical models are developed for estimating losses in consumer and producer benefits in the agricultural commodity market and changes in groundwater quality. Using corn and soybean production in the southeastern Coastal Plain as a study area, the analysis concludes that (1) effects of herbicide cancellations on groundwater quality can be very significant; (2) a cancellation does not guarantee groundwater quality improvement; (3) effects of a multiple cancellation are different from the summation of the effects of independent cancellations; and (4) weed density has a very strong effect on...

ANALYSIS OF MARKETING MARGINS IN THE U.S. LAMB INDUSTRY
Provedor de dados: 31
Autores: Capps,   Oral, Jr.; Byrne,   Patrick J.; Williams,   Gary W.
Factors affecting marketing margins were identified and assessed using a relative price spread technique.  Margins were disaggregated into slaughter-to-wholesale and wholesale-to-retail for a more complete understanding.  Marketing costs, concentration, demand, and price were used to explain variations within these margins.  Results showed that packer concentration had a significant effect on margins.  Forces of supply and demand (as represented by production and market price) and changes in marketing costs also explained the variation in margins.  A higher degree of price transmission from slaughter-to-wholesale level was observed in comparison to the wholesale-to-retail level.

A Note on Accelerated Depreciation and Investment Allowances
Provedor de dados: 31
Autores: Douglas,   Robert A.; Peterson,   Deborah C.; Kokic,   Philip; Parameswaran,   Bhamathy.
Accelerated depreciation and investment allowances are frequently requested by industry as a means of encouraging investment and promoting the adoption of socially desirable practices by farmers. Examples include the 100 per cent tax deduction for capital expenditure to combat and prevent land degradation (Section 750), and the recently introduced 10 per cent investment allowance for fodder and water storage for livestock, water conveyancing and minimum tillage equipment.  Farm level survey data are used to provide evidence of the extent and distribution of benefits to farmers that flow from different rates of depreciation, and from the introduction of a 10 per cent investment allowance. A priori, it may be difficult for the farmer (or farm financial...

THE IMPACT OF AN AGING RURAL POPULATION ON LOCAL TAX STRUCTURES

Autores: Kelsey,   Timothy W.; Smith,   Stephen M.; Luloff,   A.E.
The growing American retired population increasingly is viewed for its economic development potential.  The relationship between the elderly and local taxes may have a critical effect on this potential, however.  This paper examines the local tax implications of an increasing elderly population in communities prohibiting tax referenda.  In such communities, citizens have no direct role in tax decisions.  The elderly's attitudes towards different local taxes are examined using telephone survey data, before using aggregate data to investigate the relationship between the elderly and the specific taxes used in communities.  The results suggest that a high proportion of elderly do not affect the mix of local taxes, but that an increasing proportion does have...

AFRICA'S CHANGING AGRICULTURAL DEVELOPMENT STRATEGIES: PAST AND PRESENT PARADIGMS AS A GUIDE TO THE FUTURE
Provedor de dados: 31
Autores: Delgado,   Christopher L.
This paper looks at the often conflicting changes, frequently shaped by foreign institutions, that have affected policies for agricultural development in most  Sub-Saharan African countries since the 1960s. Reviewing past and present paradigms, Delgado contends that none of the strategies, including today's,                has provided a "magic bullet" for solving Africa's development problems. He argues that a new resolve by Africans to solve their own problems and a new willingness of international entities to invest heavily in African institutions hold the greatest hope for future development planning.

EXAMINATION OF ALTERNATIVE HETEROSCEDASTIC ERROR STRUCTURES USING EXPERIMENTAL DATA
Provedor de dados: 31
Autores: Mjelde,   James W.; Capps,   Oral, Jr.; Griffin,   Ronald C.
Impacts of alternative specifications for heteroscedastic error structures are examined by estimating various production functions for corn in Central Texas. Production- and profit- maximizing levels of input and the shape of the profit equation obtained from models not corrected for heteroscedasticity differed from those obtained from models corroded for heteroscedasticaity. Using the profit-maximizing input levels for each production function gave essentially the same estimated yield and profit, regardless of the specification for heteroscedasticity employed. Differences of up to one-quarter to one-third are noted, however, in the amount of profit-maximizing levels of input used, depending on the heteroscedasticity correction.

AGRICULTURAL WAGES AND FOOD PRICES IN EGYPT: A GOVERNORATE-LEVEL ANALYSIS FOR 1976-1993
Provedor de dados: 31
Autores: Datt,   Gaurav; Olmsted,   Jennifer.
The trend in real agricultural wages in Egypt is described well by an inverted U-shaped curve with a peak around 1985. But the rise and fall of real wages masks a complex dynamic process by which nominal wages adjust in response to changes in food prices. We use governorate-level panel data for 1976–1993 to explore the nature of this adjustment process. Our results indicate that nominal wages adjust slowly. There is a significant negative initial impact of rising food prices on real wages, though wages do catch up in the long run.

PRICE BARGAINING WITHOUT SUPPLY CONTROL
Provedor de dados: 31
Autores: Kinnucan,   Henry W.
Primary food producers are permitted to bargain as a group for higher prices.  Supply response, however, is critical to the long-run success of producer cartels.  This article presents a model that elucidates that role of supply response in agricultural price bargaining when no overt action is taken to limit quantity and participation in the cartel is voluntary.  Free-riding, for example, is seen as having a dual nature: it undermines the cartel's influence at the negotiating table but it enhances the cartel's ability to sustain a negotiated price increase by attenuating supply response.  That price bargaining can result in significant transfers from processors to producers when demand is inelastic and supply is uncontrolled is highlighted in the empirical...

Autores: Dahl,   Bruce L.; Cobia,   David W.; Dooley,   Frank J.
Economic-engineering cost data and a simulation model was used to analyze the impact of sales area size and volume and equipment configuration on costs of custom application of bulk fertilizer by cooperatives. Fixed costs accounted for most of the custom application costs regardless of sales density or size of sales area for the relevant range of these variables in North Dakota. Increasing the radius of a sales area from 5 miles to 50 miles increased average costs by $2.79/ton to $32.26 per ton in Eastern North Dakota. Doubling sales by either doubling the size of the sales area or the  sales density reduced average total costs by over a third for the smallest plant (500-ton storage) and over 40% for a 2,000-ton plant. Therefore, substantial savings,...

A nonnormal and heteroskedastic double-hurdle model is used to study household expenditure on breakfast, lunch and dinner away from home in the United States.  In the 1992-93 period, nearly 40 percent of households purchased breakfast, and about 75 percent of households purchased lunch or dinner in a two-week period.  Wife's employment has a positive effect on the probability and level of lunch and dinner expenditures but not on breakfast expenditures.  Income effects are al statistically significant and positive.  The role of household composition, other demographics and region are also important.

General Equilibrium Analysis of Supply and Factor Returns in U.S. Agriculture, 1949-91
Provedor de dados: 31
Autores: Munisamy,   Gopinath; Roe,   Terry L.
General equilibrium - open economy trade theory and time series data on the US agricultural sector are used to provide insights into the structure of agricultural supply, factor returns and linkages to the rest of the economy. Output expansion and changes in factor rental rates depend on relative factor intensities. Theoretically consistent price elasticities of supply and factor rental rates are also obtained. The effect of the rest of the economy, particularly the increase in price of services, is found to have relatively large negative impacts on agriculture. The static effects on growth of supply and factor rental rates tend to be dominated by rate effects which are shown to have strong positive effects on returns to family labor.

Using a maximum entropy technique, we estimate the market shares of each firm in an industry using the available government summary statistics such as the four-firm concentration ratio (C4) and the Herfindahl-Hirschmann Index (HHI). We show that our technique is very effective in estimating the distribution of market shares in 20 industries. Our results provide support for the recent practice of using HHI rather than C4 as the key explanatory variable in many market power studies, if only one measure is to be used.

Improving the Efficiency of Taxation of Livestock in Australia
Provedor de dados: 31
Autores: Douglas,   Robert A.
In this paper, the neutrality of the income tax provisions for livestock are examined and compared with policies in selected other countries. It is argued that the current system provides significant concessions by deferring the recognition of income. The deferral of recognition of income distorts investment decisions by providing an incentive to invest in livestock which is not available for similar investments. A more efficient system, based in part on the New Zealand National Standard Cost Scheme is suggested, as are possible transition measures.

THE RHETORIC OF DUALITY
Provedor de dados: 31
Autores: Paris,   Quirino; Caputo,   Michael R.
Agricultural economists’' view of duality has often assumed the characteristics of an ambivalent relation. During the eighties, several authors published papers which put in doubt this or that aspects of duality. This study emphasizes the notion that duality is a time-honored approach suitable for solving problems that can be expressed mathematically. Contrary to many assertions that appeared in the agricultural economics literature, duality does not seem to suffer from any theoretical limitations any more than does the formulation of the primal problem. The article presents two problems that can be solved with dual methods. The authors are incapable of deriving the same results using primal approach.

Autores: Whittaker,   Gerald W.; Lin,   Biing-Hwan; Vasavada,   Utpal.
A sample of 226 cash grain farms in the Lake States-Corn Belt region are analyzed to estimate the impact of restricting pesticide use on profits. These 226 farms are classified into small medium, and large farms according to their sale revenues. The results suggest the existence of pest management practices that could substantially reduce pesticide use without incurring economic losses. The reductions in profit associated with gradual reduction in pesticide expenditure appear to increase with farm size.

Total Quality Management Techniques Explored at Carolina Cream and Scott Specialty Foods: A Case Study
Provedor de dados: 31
Autores: Crank,   David A.
This case study examines the implementation of Total Quality Management (TOM) in two food processing firms. The two firms, which are separate divisions of a large food processor, used different implementation strategies, management leadership and employee empowerment. These strategies are compared on a strengths-and-weaknesses basis. The analysis shows that the context in which TQM is implemented is an important factor when planning such a dramatic strategic change and that the implementation of TQM or any other managerial innovation requires building teamwork and devotion of significant resources by all stakeholders in a company.

Autores: Vere,   David T.; Griffith,   Garry R.
The purpose of this paper is to evaluate the influence of alternate price determination specifications on the ability of a structural econometric model of the Australian prime lamb industry to accurately forecast saleyard lamb prices. Five variations of this model were specified according to the manner in which the farm prices of lamb were assumed to be determined. and these were used to produce 12 quarterly dynamic price forecasts over 1991:1 to 1993:4. The results confirmed the importance of the assumed nature of the price determination process in influencing the model's solution and its subsequent ability to forecast farm prices. Based on the forecasts' mean squared errors, the preferred specification was one which incorporated a traditional market...

Previous research on the relationship between diet and health has increased consumer interest in the nutritional content of specific foods. Federal programs, such as the Dietary Guidelines for Americans and The Food Pyramid, have had similar impacts. A 1994 mail survey of 3,080 Louisiana households in eight rural and urban parishes examined consumer awareness of the nutritional labeling of fresh meats and its importance. Rural respondents placed more emphasis on nutritional labeling than did urban respondents. The respondents also ranked three descriptive terms (lean, extra lean and low fat) for fat content as defined by the USDA. Eighteen percent of households ranked them correctly with white households displaying better ranking capability. These results...

Estimating the Costs of Revenue Assurance
Provedor de dados: 31
Autores: Xu,   Feng; Hart,   Chad E.; Smith,   Darnell B.; Meyers,   William H.
This study estimates the government cost of revenue assurance, one of the many proposals for the 1995 Farm Bill. Under the assumptions of nonnegativity and normality of revenue, a formula for computing the government cost of revenue assurance is derived. This formula is employed to estimate per acre revenue assurance costs at the 70, 75, and 80 percent levels of expected revenue coverage. These costs are compared with results from previous studies and with crop insurance premiums. The relative impacts of changes in yield mean, yield standard deviation, and price-yield correlation are also explored through metamodel analysis. The costs estimated for revenue assurance show that this program would result in substantial budget savings over the current program.

COMPETITION AND POLICY CONFLICTS IN CANADA-U.S. BARLEY TRADE
Provedor de dados: 31
Autores: Johnson,   D. Demcey; Wilson,   William W.
Changes in policy, institutional and competitive environments have led to increased trade and a rise in trade tensions in the Canada-U.S. barely market. These tensions stem from policies and marketing institutions that have evolved independently in these two countries. Results from a detailed spatial equilibrium model of the Canada- U.S. barley market are presented in this article. Simulations are used to quantify effects of U.S. import restrictions; removal of Canadian rail subsidies, different Export Enhancement Program (EEP) subsidy levels, restoration of Conservation Reserve Program (CRP) acres to U.S. production, and retention of Canadian Wheat Board control over Canadian barley sales—all of which affect trade flows in the barley sector.

ESTIMATING THE OPPORTUNITY COST OF TIME WHEN LABOR SUPPLY DECISIONS ARE INSTITUTIONALLY CONSTRAINED
Provedor de dados: 31
Autores: Phagan,   Tiffany D.
Policy decisions concerning options for the recreational use of natural resources typically call for recreation demand and benefit measures that are not revealed by market prices and must therefore be estimated. Travel cost models use a proxy for the unobserved market price to estimate recreation demand. The "price" is typically equal to the sum of time and monetary costs of traveling to the recreation site in addition to any site access fees. This price proxy allows individual recreation demand schedules and their corresponding benefits to be estimated. The time element of the price proxy is converted to its price equivalent and is referred to as the "opportunity cost of time". Conventional methods use the marginal wage as the rate of conversion....

The Erosion Productivity Impact Calculator (EPIC) model was validated using long-term data collected for two southwest Iowa watersheds in the Deep Loess Soil Region, which have been cropped in continuous corn Zea Mays L. under two different tillage systems (conventional tillage and ridge-till). The annual hydrologic balance was calibrated for both watersheds during 1988-94 by adjusting the runoff curve numbers and residue effects on soil evaporation. Model validation was performed for 1976-87, using both summary statistics (means or medians) and parametric and nonparametric statistical tests. The errors between the 12-year predicted and observed means or medians were less than 10 percent for nearly all of the hydrologic and environmental indicators, with...

The objective of this study was to examine the effect of nutrition  and health on labor productivity for women and men workers on subsistence farm households. The study emerged from the well founded Efficiency Wage Hypothesis which asserts that nutrition affects labor productivity in subsistence economies.  This study develops the Efficiency Wage Hypothesis further by including an anthropometric measure of health along with caloric intake and other production inputs in the productivity analysis The conceptual model was based on an economic model of household behavior developed by Gary Becker.  Through optimization it was shown that consumption and production decisions were not separable. The relevant step was to estimate an inherently non-linear production...

International Trade in Exhaustible Resources: A Cartel-Competitive Fringe Model
Provedor de dados: 31
Autores: Karp,   Larry S.; Tahvonen,   Olli.
We characterize the open-loop and the Markov perfect Stackelberg equilibria for a differential game in which a cartel and a fringe extract a nonrenewable resource. Both agents have stock dependent costs. The comparison of initial market shares, across different equilibria, depends on which firm has the cost advantage. The cartel's steady state market share is largest in the open loop equilibrium and smallest in the competitive equilibrium. The initial price may be larger in the Markov equilibria, so a decrease in market power may make the equilibrium appear less competitive. The benefit to cartelization increases with market share.

Estimating the Net Energy Balance of Corn Ethanol
Provedor de dados: 31
Autores: Shapouri,   Hosein; Duffield,   James A.; Graboski,   Michael S.
Studies conducted since the late 1970's have estimated the net energy value of corn ethanol. However, variations in data and assumptions used among the studies have resulted in a wide range of estimates. This study identifies the factors causing this wide variation and develops a more consistent estimate. We conclude that the net energy value of corn ethanol has become positive in recent years due to technological advances in ethanol conversion and increased efficiency in farm production. We show that corn ethanol is energy efficient as indicated by an energy ratio of 1.24.

Environment in Three Classes of Endogenous Growth Models
Provedor de dados: 31
Autores: Elbasha,   Elamin H.; Roe,   Terry L.
The implications of environmental externalities are studied within three classes of endogenous growth models viz. the linear technology models, the human capital models, and the R&amp;D and innovation models. The long-run rate of economic growth changes when environmental extemalities are introduced; the direction of change depends on the severity of extemalities and the intertemporal elasticity of substitution. The presence of environmental externalities cause the decentralized growth rate to diverge from the efficient rate. Which rate is bigger than the other depends, among other things, on the valuation of consumption relative to environmental quality. Several policy changes to align the two paths are discussed. The models are calibrated to U.S. data.

This paper examines the extent to which the Uruguay Round's implementation and other policy reforms are likely to alter the fortunes of Australasian and other farmers. It finds that, compared with other structural adjustment pressures, the Uruguay Round per se is likely to have a positive but relatively minor effect. Nonetheless, the net gains are likely to be very substantial relative to the efforts expended by the Cairns Group to ensure agricultural reform remained in the final agreement of the Round. Those gains will be larger the more the Cairns Group remains vigilant in ensuring (a) that the promised cuts in protection are actually implemented, (b) that the reforms are not accompanied by the imposition of compensating support policies and (c) that...

Tracking Foodborne Pathogens from Farm to Table: Data Needs to Evaluate Control Options
Provedor de dados: 31
Food safety policymakers and scientists came together at a conference in January 1995 to evaluate data available for analyzing control of foodborne microbial pathogens. This proceedings starts with data regarding human illnesses associated with foodborne pathogens and moves backwards in the food chain to examine pathogen data in the processing sector and at the farm level. Of special concern is the inability to link pathogen data throughout the food chain. Analytical tools to evaluate the impact of changing production and consumption practices on foodborne disease risks and their economic consequences are presented. The available data are examined to see how well they meet current analytical needs to support policy analysis. The policymaker roundtable...

This article systematically estimates the allocative efficiency losses in the U.S. food and tobacco manufacturing industries under alternative oligopoly pricing regimes using a formal model of oligopoly. Using 1987 data for 44 industries and an industry-wide oligopoly pricing scheme, these losses were estimated at approximately 3% of sales--2% in the food industries and 19% in the tobacco industries. Five additional oligopoly pricing regimes, four of which are price leaderships, are simulated and their results compared and tested relative to the industry-wide pricing regime. Findings underscore the importance of cost structure assumptions and that the impact of the type of oligopoly behavior assumed is not as dramatic when differences in demand and cost...

Benefits of Protecting Rural Water Quality: An Empirical Analysis
Provedor de dados: 31
Autores: Crutchfield,   Stephen R.; Feather,   Peter; Hellerstein,   Daniel.
Concerns about the impact of farm production on the quality of the Nation's drinking and recreational water resources have risen over the past 10 years. Because point sources of pollution were controlled first, agricultural nonpoint sources have become the Nation's largest remaining single water-quality problem. Both public and private costs of policies that address the conflict between agricultural production and water quality are relevant, but measuring the off-farm benefits and costs of changing water quality is difficult. Many of the values placed on these resources are not measured in traditional ways through market prices. This report explores the use of nonmarket valuation methods to estimate the benefits of protecting or improving rural water...

APPROACHES TO RURAL DEVELOPMENT IN THE THIRD WORLD: LESSONS FOR SOUTH AFRICA
Provedor de dados: 31
Autores: Machethe,   Charles Lepepeule.
The eradication of rural poverty has been a major concern of Third World governments and donor agencies for many decades. Various approaches have been used to eradicate rural poverty. Community Development (CD) emerged as the dominant approach in the early 1950s in many Third World countries, especially in Asia and Latin America. However, the CD movement declined in the 1960s when it was realized that it was not effective in reaching the poor. The French counterpart of CD, animation rurale(AR), was adopted in Francophone countries, especially in Africa in the late 1960s (Geller et al., 1980). Disappointment with the results of CD and AR gave rise to Integrated Rural Development (IRD) and the Basic Needs (BN) approaches in the early 1970s. However, by 1980...

DISTANCE EDUCATION VIA TELEVISION: SOME REFLECTIONS AFTER FOUR YEARS
Provedor de dados: 31
Autores: Kendrick,   Jim.
Four years of televising a university course for delivery to an audience of agricultural producers provides some reflections on the feasibility of combining traditional classroom instruction with in-depth extension educational programs.  There are a sizable number of active agricultural producers who are eager to study academic topics in greater depth than could be obtained in traditional workshops or seminars.  It seems possible to overcome many obstacles that earlier suggested distance education via television was not feasible from an administrative, budgetary or client acceptance point of view.  The results seem worth the effort, with the providing institution benefiting from increased national recognition.

Efficiency properties of taxation of agriculture are difficult to assess because some capital income is taxed according to an expenditure base, some to a real income base and some to a nominal income base.

Data obtained from dietary intake surveys are often used to estimate the proportion of the population with insufficient (or excessive) intake of certain dietary components.  It is generally agreed that the usual or long-run average intake of a nutrient is the appropriate measure of an individual's intake.  In this light, assessments of the dietary status of the population should be based on the distribution of usual intakes for each dietary component. Several methods have been proposed for estimating the distributions of usual intakes from dietary data.  The methodology presented by Nusser et al. (1995) is very appealing, since it accounts for all of the attributes of dietary intake data, and explicitly recognizes that when data are collected on...

PERFORMANCE OF MINNESOTA BANKS: AN ANALYSIS OF STRATEGIC MANAGEMENT CHOICES
Provedor de dados: 31
Autores: Stensland,   Jeffrey; Pederson,   Glenn D.
The success of various bank management strategies is evaluated using data from banks located in Minnesota during 1988-1994. These strategies are identified using a combination of data from financial statements and survey data.  Each strategy is evaluated based on its effect on rate of return on assets and rate of return on equity.  The study finds that cost containment strategies are relatively more successful than strategies which emphasize the expansion of services.  The implications for the future structure of the Minnesota banking industry are discussed.

DO FARM BUSINESSES AND BIG BUSINESSES APPLY DIFFERENT CAPITAL BUDGETING PROCEDURES?
Provedor de dados: 31
Autores: Arthurton,   Daniel A.; Moffitt,   L. Joe; Allen,   P. Geoffrey; Cox,   Douglas A.
Recent studies of capital budgeting procedures used by business executives suggest increasing use of present value methods.  This study compares Massachusetts greenhouse business managers use of capital budgeting procedures to those of Fortune 1000 firms.  Results indicate that different capital budgeting procedures are used and that the payback criterion remains the most popular for the farm firms studied.  Some implications for Extension finance educators are drawn.

Women's Labor Force Participation During and After Communism: A Study of the Czech Republic and Slovakia
Provedor de dados: 31
Autores: Chase,   Robert S.
This research uses four micro-data sets to examine differences in married women's labor force participation between Communist and post- Communist Czech Republic and Slovakia. Descriptive statistics show that participation has dropped in both regions following the regime change, particularly for young women. To explain this phenomenon, one hypothesis is that own and spouse wage elasticities of participation are the same during and after Communism and the behavior change results from different offered wages. An alternative hypothesis is that wage elasticities changed. We expect higher elasticities in the regime which offers a broader set of options to families making time allocation decisions. Rejecting the hypothesis that elasticities are unchanged, the...

THE ECONOMIC VALUE OF HIKING: FURTHER CONSIDERATIONS OF OPPORTUNITY COST OF TIME IN RECREATIONAL DEMAND MODELS
Provedor de dados: 31
Autores: Casey,   James F.; Vukina,   Tomislav; Danielson,   Leon E.
The paper tests two alternative specifications for the opportunity cost of time in travel cost models. The standard travel cost survey design is enriched to include a contingent valuation type question about peoples' willingness to accept compensation to forgo a precisely defined recreational experience. It is hypothesized that individually revealed value of time more appropriately reflects the opportunity costs of time associated with a particular aspect of recreation than the wage rate which measures the trade-off between work and leisure generally. The results seem to indicate a better overall fit for the models with the elicited value of individual consumer's time than for the models with the more traditional hourly earnings (wage rates).

TECHNOLOGY AND MANAGEMENT IN MAURITANIAN CEPHALOPOD FISHERIES
Provedor de dados: 31
Autores: Diop,   Hamady; Kazmierczak,   Richard F., Jr.
If the technology in a multi-species fishery is such that there is jointness in inputs and non-separability between inputs and outputs, then management on a species-by-species basis may lead to unintended outcomes, including over-exploitation of the resource. This study investigates the nature of the technical and economic relationships underlying the 1989-1990 Mauritanian cephalopod fishery by estimating a system of dual output supply functions derived from a generalized Leontief revenue function.  Model results indicate the existence of jointness in inputs and non-separability between inputs and outputs in the fishery.  Cross-price elasticities indicated a number of substitute and complementary relationships, with these relationships changing in...

In 1992 the National Oceanic and Atmospheric Administration (NOAA) convened a panel of prominent social scientists to assess the reliability of natural resource damage estimates derived from contingent valuation (CV). The product of the Panel's deliberations was a report that laid out a set of recommended guidelines for CV survey design, administration, and data analysis. One of the Panel's recommendations was that CV surveys should employ a referendum approach. This method describes a choice mechanism that asks each respondent how they would vote if faced with a particular program and the prospect of paying for the program through some means, such as higher taxes. The Panel also recommended that CV referendum questions which commonly use only "for" or...

APPLICATIONS OF SOCIAL CAPITAL THEORY
Provedor de dados: 31
Autores: Schmid,   A. Allan; Robison,   Lindon J.
Experiments and studies were conducted to investigate the role of social capital.  Social capital (relationship to others) is a productive asset which is a substitute for and complement to other productive assets.  The productivity of social capital leads to the expectation that firms and individuals invest in relationships.  Data were collected to answer the following questions: Does the identity (relationship) of trading partners affect selling and buying prices; the acceptance of catastrophic risk; the choice of share or cash leases in agriculture; loan approval; and the banks investment to retain customers?  The evidence is in the affirmative.

THE CHANGING RURAL POLICY CONTEXT
Provedor de dados: 31
Autores: Smith,   Stephen M.
A characteristic of our rural policies is that we seem to treat farm policy and other rural policy as if agriculture and the rest of the rural economy and society are separate.  Literature from each perspective tends to ignore the existence and context of the other.  There has been enough change in the rural context, however, to require a different approach to rural policy analysis and formulation.  We must start from a comprehensive view of the rural economy, including both the agricultural and nonagricultural rural economies.  The paper discusses issues that have changed the rural policy context: the changed rural economic structure, macro forces, farm-nonfarm interdependence, and the political arena.  These changing contexts create new opportunities for...

RECENT DUALITY CONTRIBUTIONS IN PRODUCTION ECONOMICS
Provedor de dados: 31
Autores: Shumway,   C. Richard.
This article is a limited assessment of the agricultural production economics literature since 1982 that resulted from dual modeling approaches. Contributions have removed several perceived obstacles to dual modeling, such as testing curvature, identifying the technology when prices are collinear, and examining dynamics of production. Some contributions have also removed obstacles to primal modeling. Dual methods have been used in risk applications only recently and still appear less convenient than primal methods. Convenience may become the primary criterion for selecting primal or dual methods.

A TRADE NETWORK GAME WITH ENDOGENOUS PARTNER SELECTION
Provedor de dados: 31
Autores: Tesfatsion,   Leigh.
This paper develops a Trade Network Game (TNG) that combines evolutionary game play with endogenous partner selection. Resource-constrained buyers and sellers choose and refuse trade partners on the basis of continually updated expected payoffs. Partner selection takes place in accordance with a "deferred choice and refusal" mechanism that is shown to have interesting stability, optimality, and uniqueness properties.  The iterated prisoner's dilemma strategies used by buyers and sellers to conduct their trades are evolved over time via a genetic algorithm that biases reproduction in favor of strategies that have been successful in past trades.  The TNG is shown to encompass a variety of economic applications, such as job search games, labor markets...

Optimal Design of a Voluntary Green Payment Program Under Asymmetric Information
Provedor de dados: 31
Autores: Wu,   JunJie; Babcock,   Bruce A.
Green payment programs, where the government pays farmers directly for environmental benefits, have been proposed as an alternative to the current method of achieving environmental benefits by restricting farming practices in exchange for deficiency payments. This paper presents a voluntary green payment program using the principles of mechanism design under asymmetric information.  The information asymmetry arises because government knows only the distribution of individual farmers' production situations, rather than farm-specific information.  The program is applied to irrigated corn production in the Oklahoma Panhandle, where nitrogen fertilizer is a nonpoint source of pollution.  We demonstrate empirically that a green payment program can increase farm...

Autores: Lambert,   David K.; Shonkwiler,   John Scott.
This study attempts to link factors affecting the demand for Bureau of Land Management grazing to perceived changes in permittee welfare over the 1962-92 period. Annual demand for federal forage is found to be sensitive to active preference, beef cow and breeding ewe inventories, and grazing fees and nonfee allotment utilization costs. No evidence is found to support the notion that the demand for grazing has been affected by changes in property rights associated with the federal grazing permit that are not reflected in higher user costs. The total decrease in welfare generated from the permit that are not reflected in higher user costs. The total decrease in welfare generated from the permit to graze public lands has been about 9% per authorized cattle...

VALUATION OF INTANGIBLE CAPITAL IN AGRICULTURE
Provedor de dados: 31
Autores: White,   Fred C.
This study examines the valuation of research as intangible capital in agriculture using Tobin's q theory. The market value of public research capital is estimated to be 8.6 times higher than conventional assets. Private research capital is valued 5.2 times higher than conventional assets. The estimated valuation multiplier for all farm assets dropped 1/3 over the last decade. In recent years the valuation multiplier has dropped below a dollar, which indicated the market is undervaluing farm assets.

MEASURING THE ENVIRONMENTAL IMPACTS OF ECONOMIC CHANGE:  THE CASE OF LAND DEGRADATION IN PHILIPPINE AGRICULTURE
Provedor de dados: 31
Autores: Coxhead,   Ian A.; Shively,   Gerald E.
We evaluate the on-site land degradation effects of economic changes occurring both within agriculture and elsewhere in the Philippine economy, simulated with the APEX applied general equilibrium model. We derive changes in land degradation rates from changes in land use in rainfed annual crops, using Philippine data on upland erosion under a range of crops, rainfall patterns and slopes. In general equilibrium, land degradation rates are affected by endogenous price changes as well as by direct interventions in agriculture and agricultural processing sectors. We examine the effects of technical progress in corn, and of a capital subsidy to the rice and corn milling sector. Using the nutrient replacement cost method, we calculate the value of changes in...

Provedor de dados: 31
Autores: Taff,   Steven J.; Senjem,   Norman.
In this paper, we postulate that uncertainties associated with nonpoint source pollution and with certain features of pollutant trading may tend to outweigh the potential benefits of pollutant trading from the standpoint of regulatory agencies and point source dischargers. After identifying several major sources of such uncertainties, we outline a trading scheme for a typical phosphorus-polluted water body in an agricultural watershed.  The scheme limits uncertainty while preserving the efficiency-seeking features of trading to effect water quality improvements.

CLIMATE CHANGE AND GRAIN PRODUCTION IN THE UNITED STATES: COMPARING AGRO-CLIMATIC AND ECONOMIC EFFECTS
Provedor de dados: 31
Autores: Li,   Zhuang; Mount,   Timothy D.; Kaiser,   Harry M.
The analysis is based on an integrated climatic, agronomic and economic model of grain production in the midwestern region of the U.S. The model represents a typical farm and the objective is to select an optimum combination of cultivars for four crops (maize, soybean, wheat and sorghum) conditionally on climate, soil characteristics and the prices of the four crops. The first part of the analysis uses a complete two-way factorial design to estimate the effects of five climatic and agronomic variables and the four prices on yields, total production and net return. With this design, variability can be allocated uniquely to individual explanatory variables. As expected, prices have little effect on yields. For total production and net return, temperature and...

The rapid introduction of new chemicals has outpaced the scientific community’s ability to test for toxicity and interpret its results. Testing and interpretation is confounded by the natural presence of chemicals in food. Limitations of animal experiments are discussed along with problems of calculating and communication risk, the latter being subject to public fear and outrage.

This summary and analysis of 321 New York dairy farm businesses demonstrates the use of cash accounting and accrual adjustments to measure farm profitability, cash flow, financial performance, and costs of producing milk. Traditional methods of analyzing dairy farm businesses are combined with improved evaluation techniques to show the relationship between good management performance and financial success. These farms averaged 151 cows per farm and 20,091 pounds of milk sold per cow in 1994, which are above the average size and management level of all New York dairy farms. Net farm income excluding appreciation, which is the return to the operator's labor, management, capital, and other unpaid family labor, averaged $56,084 per farm. The rate of return...

Supermarket Bakery Consumers: Attitudes, Preferences, Behaviors
Provedor de dados: 31
Autores: McLaughlin,   Edward W.; Hawkes,   Gerard F.; Park,   Kristen; Perosio,   Debra J.
For at least a decade, supermarket operators have turned increasingly to fresh foods for the strategic direction of their business by remodeling existing stores and building new stores to feature and emphasize produce, the delicatessen, the bakery, and other perishable departments. These departments have been the fastest growing and offer the greatest future sales potential as consumer demand for "fresh" and "ready to eat" prepared foods continues to grow. Despite these prospects, little is actually known about how consumers perceive and respond to product offerings and retailer initiatives in perishable departments.

Non-market Valuation Biases Due to Aboriginal Cultural Characteristics in Northern Saskatchewan: The Values Structures Component
Provedor de dados: 31
Autores: Murray,   Eloise C.; Adamowicz,   Wiktor L.; Beckley,   Thomas M.; MacDonald,   Darla Hatton; Just,   Lesley; Luckert,   Martin K.; Phillips,   William.
Current non-market valuation techniques have been developed based on assumptions about values held within the Eurocentred culture. Contentions between cultures over natural resources are hypothesized to occur because of differences in held values resulting in different values being assigned to the resources in question. This study measured the held values of an Aboriginal band in Northern Saskatchewan as the first dimension of a non-market valuation study of natural resources. These held value structures are presented noting differences by age and gender and in comparison with the local Non-Aboriginal community and another Aboriginal group in northern Alberta.

Role of Terms of Trade in Indian Agricultural Growth: A National and State Level Analysis
Provedor de dados: 31
Autores: Hazell,   Peter B.R.; Misra,   V.N.; Hojjati,   Behjat.
Using time series data, this paper analyses the relative contributions of terms of trade and non-price variables in explaining agricultural growth in recent decades in India. Agricultural growth is largely explained by expansion of irrigation, (which in the model is also a proxy for HYVs and other capital investments), and, until the 1970s, by increases in the net cultivated area. Agricultural output is inelastic, and is becoming increasingly more so over time. The terms of trade was not an important factor in explaining past growth. Even during the late 1960s and early 1970s when the terms of trade improved by 18 percent for agriculture, they only accounted for 15 percent of the growth in output. Increases in agricultural output are also found to worsen...

INTEGRATION OF AGRICULTURE AND TECHNOLOGICAL CHANGE
Provedor de dados: 31
Autores: White,   Fred C.
Market structure has implication for research policies.  The public sector reduced its support for technological change for poultry relative to beef and pork after poultry became integrated.  However, market integration causes private sector research to be below the optimal level from society's perspective.  In order to get the appropriate response from the private sector, the public sector should not reduce its support for technological change after market integration.  Instead, the public sector should increase its support for research such as basic science that complements private sector research.

TOWARD A FRAMEWORK FOR ANALYZING MULTIMARKET CONTACT AND MULTINATIONAL COMPETITION
Provedor de dados: 31
Autores: Ding,   John Y.
The possibility of noncompetitive behavior resulting from multimarket contact (i.e., mutual forbearance) has always been a source of concern among industrial organization economists and policy makers. The increasing global presence of multinational corporations has added a new dimension to the analysis of multimarket competition. Their growing influence on the world economy poses new questions about the effects of multinational competition on domestic welfare and the international competitiveness of domestic industries. Recent developments in the interface between industrial organization and international trade theories provide new research opportunities and may shed some light on the economic consequences of multinational competition and its policy...

Improving the Measurement and Analysis of African Agricultural Productivity: Promoting Complementarities between Micro and Macro Data
Provedor de dados: 31
Autores: Kelly,   Valerie A.; Hopkins,   Jane; Reardon,   Thomas; Crawford,   Eric W.
A wide variety of multilateral and bilateral agencies, private sector firms, and African governments have a need for high quality, reliable data on agricultural productivity. This paper identifies numerous situations where poor data lead to incorrect estimates of African land and labor productivity. The paper argues that better coordination of macro, meso, and micro data collection, reporting, and analysis efforts can lower costs and improve our ability to monitor trends and to quantify determinants of agricultural productivity. Seven key points are made in the discussion: (1) Missing or poorly measured variables used in the numerator (output) or denominator (land and labor, for example) are biasing productivity ratios; (2) In most cases, these errors...

An Investigation of Equivalent Scales in Demand Using the 191 Latvian Household Budget Survey
Provedor de dados: 31
Autores: Hossain,   Ferdaus; Jensen,   Helen H.
The 1991 Latvia household budget survey provided data for establishing basic information about food consumption levels and patterns in Latvia during the first year of major economic reforms.  This study evaluates one aspect of economic decision making of households: how income is allocated for consumption of various broad categories of food items. The analysis uses the 1991 data to examine the importance of income and household composition on food expenditures.  Estimated income elasticities for various food commodities suggest the magnitude of changes in real household income that have occurred in Latvia.  With relativity low income elasticities (estimated from the 1991 data), declines in household income would not be met by significant reductions in food...

GAME MODELS OF ENVIRONMENTAL POLICY IN AN OPEN ECONOMY
Provedor de dados: 31
Autores: Batabyal,   Amitrajeet A.
In this paper we study some aspects of the question of international environmental regulation from a game theoretic perspective. We address two broad questions. First, we examine the circumstances under which the pursuit of unilateral environmental policy by a country in a Stackelberg game will make that country worse off. Second, we study the effects of environmental regulation by means of alternate price control instruments in a Stackelberg game where there is transboundary pollution. We find that there are plausible theoretical circumstances in which the pursuit of unilateral environmental policy is not a good idea. Further, we show that in choosing between alternate pollution control instruments, national governments typically face a tradeoff between...

This study presents a new explanation of asymmetric price behavior infood markets based on the presence of transactions costs,and provides evidence from a developing country. Price liberalization can in many cases be insufficient for efficien toperation of African food markets. This is mainly due to the existence of significant transactions costs, caused by deficient infrastructure and information systems. A model based on search costs and kinked demand curves is used to explain asymmetric price behavior in retail markets in Kinshasa (Zaire).

Competitive Relationship of Three Warm-Season Turfgrass Species
Provedor de dados: 31
Autores: Adrian,   John L., Jr.; Duffy,   Patricia A.; Lloyd,   Michael.
The competitive position of three warm-season turf species commonly grown in the South (bermudagrass, centipedegrass, and zoysiagrass) is evaluated for a farm with 100 acres available to allocate to turfgrass-sod production. A multiperiod linear programming model is used to determine optimal mixes of grasses and resulting net returns for a seven-year planning horizon. Within current observable price ranges, variation in the prices of the different grasses has little impact on the profit-maximizing combination of grasses. Bermudagrass, with the shorter production cycle and positive influence on cash flow, dominates the higher-valued, longer-production-cycle alternative grasses. Availability of initial money capital from internal sources does not alter the...

CONTINGENT VALUATION IN FOOD POLICY ANALYSIS: A CASE STUDY OF A PESTICIDE-RESIDUE RISK REDUCTION
Provedor de dados: 31
Autores: Buzby,   Jean C.; Ready,   Richard C.; Skees,   Jerry R.
This study demonstrates how contingent valuation techniques can be used in a cost-benefit analysis of a food safety policy issue. The analysis focuses on banning a specific post harvest pesticide used in fresh grapefruit packinghouses. Benefits of the ban are measured using consumers' aggregated willingness to pay (WTP) for safer grapefruit. A national contingent valuation survey used the payment card method to obtain WTP data. Costs of the ban stem predominantly from increased post harvest losses and were estimated using a model of the market for Florida grapefruit. Results indicate that benefits of the ban outweigh costs.

Factors Related to the Adoption of rBST Among a Population of Farmers in Ontario County, New York
Provedor de dados: 31
Autores: Lyson,   Thomas A.; Tauer,   Loren W.; Welsh,   Rick.
A population of 50 dairy farms in Upstate New York was surveyed in 1993 to collect data on the organizational and structural characteristics of their farm businesses and households, including information about their attitudes towards rBST. In the fall of 1994, six months after rBST was approved for general use, this same population of farmers was resurveyed. Findings show that in 1994 one-half of the farmers were using rBST or planned to use it within one year. Compared to non-adopters, farmers who adopted rBST were generally larger, used more advanced dairy technologies, and reported higher production herd averages. Differences in attitudes and goals were also observed. Implications of rBST for the future organizational structure of New York dairies are...

AN AUTOMATED ECONOMETRIC APPROACH FOR ESTIMATING AND REPORTING DAILY COTTON MARKET PRICES
Provedor de dados: 31
Autores: Brown,   Jeff E.; Ethridge,   Don E.; Hudson,   Darren; Engels,   Carlos.
An automated price reporting system developed through computer technology and hedonic price theory is used to estimate daily cotton market prices, premiums, and discounts. This objective approach for reporting cotton market prices was developed to complement the objective measures of high volume instrument grading of cotton. The computerized, econometric system is limited to the Texas and Oklahoma marketing regions where sales are readily available from electronic markets. The econometric based system has shown all the characteristics of an efficient price reporting system; it is accurate, reliable, consistent, and repeatable in its working process and price estimates.

FARM PROGRAMS AND THE ENVIRONMENT: THE CASE FOR A LIMITED LAND PAYMENT
Provedor de dados: 31
Autores: Peterson,   Willis L.
The results of estimating reduced form supply and input demand functions suggest that farm programs have increased the area planted to corn and soybeans in the corn belt by about 12 percent, and increased fertilizer and chemical use per acre by about 18 percent. It is argued that a limited land payment (LLP) program would be neutral in its effect on the environment while helping to preserve family farms and rural communities.

The Strategic Interdependence of a Shared Water Aquifer: A General Equilibrium Analysis
Provedor de dados: 31
Autores: Roe,   Terry L.; Diao,   Xinshen.
In a region with shared water aquifers, the use of water by one country becomes an externality to another. A policy to subsidize water is shown to lead to both countries being made worse off, but is likely to be supported by special interests having water rights, and those in sectors such as agricultural that uses water relatively intensively. The unilateral water tax will reduce own country's GNP and rise GNP in the other country. Only when both countries impose a tax cooperatively, will GNP rise in both countries.

The Economic, Environmental, and Fiscal Impacts of a Targeted Renewal of Conservation Reserve Program Contracts
Provedor de dados: 31
Autores: Babcock,   Bruce A.; Lakshminarayan,   P.G.; Wu,   JunJie.
What to do with CRP contracts as they expire is one of the most pressing issues confronting U.S. agricultural policymakers in 1995. Because CRP renewal will compete in 19959 with other agricultural programs for funding, greater attention will be paid to improve targeting of payments to maintain a significant portion of existing environmental and farm benefits at a reduced program cost.  We consider three alternative renewal criteria: (1) renewal of least expensive land first (cost-raking), (2) renewal of most environmentally sensitive land first (benefit-ranking), and (3) renewal of land according to the cost per unit of environmental benefit offered (cost/benefit-ranking). Environmental indicators used to measure benefits include sheet and rill erosion,...

JAKARTA, INDONESIA: THE ECONOMICS OF WATER AND WASTE
Provedor de dados: 31

Jakarta's main streets are landscaped, manicured, and modern.  Off these streets, however, the environment is that of an overgrown village.  Compared to other Asian cities, Jakarta's drinking water, sewerage treatment, solid waste disposal, and general environment are seriously deficient. This case study briefly outlines the deficiencies.  Less than one-fourth the residents have piped water.  Almost no one is attached to a sewer.  One-third of the city's solid waste never reaches the landfill. The source of the problems is historical -- for a long time, the problems of this rapidly growing city were not adequately addressed.  And the problem has become worse in recent years by the policymakers' concern with providing first-class service to all, despite the...

LAND ALLOCATION IN THE PRESENCE OF ESTIMATION RISK
Provedor de dados: 31
Autores: Lence,   Sergio H.; Hayes,   Dermot J.
Estimation risk occurs when parameters relevant for decision making are uncertain. Bayes'’ criterion is consistent with expected-utility maximization in the presence of estimation risk. This article examines optimal (Bayes’') land allocations and land allocations obtained using the traditional plug-in approach and two alternative decision rules. Bayes’' allocations are much better economically than the other allocations when there are few sample observations relative to activities. Calculation of certainty equivalent returns (CERs) with estimation risk is also discussed and illustrated. CERs are typically (and incorrectly) calculated with the plug-in approach. Plug-in CERs may be extremely misleading.

A NOTE: A CLARIFICATION OF THE ROLE OF YIELD UNCERTAINTY IN INFLUENCING OVER-QUOTA PRODUCTION
Provedor de dados: 31
Autores: Fraser,   Rob W.
The literature shows that the influence of yield uncertainty on production relative to quota is ambiguous in the case of a single market. This paper uses a two-market framework (quota market and secondary market) with multiplicative yield uncertainty to show that if over-quota production in the absence of yield uncertainty is profitable, then the presence of yield uncertainty is unambiguously a further stimulus to over-quota production. The analysis is discussed in the context of recent changes to the marketing arrangements for Western Australian potatoes.

ANALYSIS OF U.S. EXPORT ENHANCEMENT TARGETING AND BONUS DETERMINATION CRITERIA
Provedor de dados: 31
Autores: Haley,   Stephen L.; Skully,   David W.
This research analyzes the criteria set from which policymakers have selected import markets to target EEP wheat bonuses. Results presented herein indicate that the administration of EEP has favored no specific criterion -- rather, the emphasis placed on various criteria has fluctuated over time. Although putting pressure on the EU was a much repeated justification for the program, expanding U.s. wheat exports and pressuring the Canadians guided targeting allocations as much as, if not more than, pressuring the EU. This research also develops a method for predicting which wheat import markets are likely to be important in the future, based on an identification of specific policy objectives.

Tax Traps and Opportunities Associated with Family Farm Transfers
Provedor de dados: 31
Autores: Smith,   Stuart F.
Transferring farm property from the Senior to the Junior farm family generation with conventional methods such as sales and debt transfer can cause tax traps or burdens. The most serious tax traps and related problems occur when the farm business being transferred has high debt and is below optimum size and profitability. Farm families should recognize the conditions that cause tax traps when farm property is transferred. Alternative planning and transfer strategies can be used to avoid serious tax traps and maximize after tax income.

STOCHASTIC INTEREST RATES AND PRICE DISCOVERY IN SELECTED COMMODITY MARKETS
Provedor de dados: 31
Autores: Zapata,   Hector O.; Fortenbery,   T. Randall.
The temporal relationship between Chicago corn and soybean cash prices, nearby futures prices, and interest rates is examined using daily 1980-1989 data. Johansen cointegration tests suggest joint movement of the three series over the data period considered. In addition, analyses of individual crop years, which is consistent with previous work, shows co-movement between cash, futures, and interest rates in years when bivariate cointegration between cash and futures prices was not found. The results provide initial empirical evidence that a potential limitation of previous research in the study of cash- futures simple efficiency has been the exclusion of the interest rate as a common stochastic factor explaining equilibrium in models of cash and futures...

THE RESPONSIVENESS OF U.S. RICE ACREAGE TO PRICE AND PRODUCTION COSTS
Provedor de dados: 31
Autores: Salassi,   Michael E.
Ordinary least squares and seemingly unrelated regression procedures were used to analyze the impacts of changes in rice prices and production costs on U.S. rice planted acreage. National and regional response models were estimated over the 1970-92 period. Supply-inducing prices of rice were estimated as a function of effective rice support prices and seasonal average market prices. Expected production costs per acre were estimated using lagged actual total variable cash production expenses per acre adjusted by the previous 3-year average annual change in variable expenses. Estimated short-run price and production cost elasticities were found to be inelastic at the national level. However, the magnitude of the production cost elasticities were found to be...

Gender Differentials in Farm Productivity: Implications For Household Efficiency and Agricultural Policy
Provedor de dados: 31
Autores: Alderman,   Harold; Hoddinott,   John; Haddad,   Lawrence James; Udry,   Christopher R.
Within many African households, agricultural production is simultaneously carried out on many plots controlled by different members of the household. Detailed plot-level agronomic data from Burkina Faso provides striking evidence of inefficiencies in the allocation of factors of production across the plots controlled by different members of the household. Production function estimates imply that the value of household output could be increased by 10 to 20 percent by reallocating currently-used factors of production across plots. This finding contradicts standard models of agricultural households. A richer model of behavior, which recognizes that the individuals who comprise a household compete as well as cooperate, has important implications for the...

Agricultural Input Market Reforms. A Review of Selected Literature
Provedor de dados: 31
Autores: Goletti,   Francesco; Alfano,   Anna.
The objective of this paper is to derive lessons from selected literature concerning the impact and the conditions of successful agricultural input market reform. The agricultural inputs of interest in this review are: fertilizers, seeds, agricultural equipment, pesticides, and livestock services and health inputs. The paper examines the rationale for market reform, its impact on growth, productivity, and income of farmers, and the conditions for success. Six main conclusions emerge from this review. First, market structures are the result of evolutionary processes that accompany the adoption and the diffusion of modern technology in agriculture. Second, the development of markets and private sector cannot occur unless an adequate infrastructure is in...

Local Organizations For Natural Resource Management: Lessons From Theoretical and Empirical Literature
Provedor de dados: 31
Autores: Rasmussen,   Lise Nordvig; Meinzen-Dick,   Ruth Suseela.
The sustainability of natural resource management depends not only on  appropriate technology and prices, but also upon the institutions involved in resource  management at the local level.  Heavy state involvement in natural resource management  has been justified based on the prevalence of market failures, notably the positive and  negative externalities and the strategic importance of the resources. Policies of devolving  management responsibility from the state to users have become increasingly widespread  in response to the performance deficiencies of government agencies, the fiscal crisis of  the state, and broader policies of decentralization.  The success of these policies depends  upon the local capacity for collective action, but the factors that...

THE BIOECONOMICS OF REGULATING NITRATES IN GROUNDWATER FROM AGRICULTURAL PRODUCTION THROUGH TAXES, QUANTITY RESTRICTIONS, AND POLLUTION PERMITS
Provedor de dados: 31
Autores: Thomas,   Arthur C.; Boisvert,   Richard N.
Agricultural production in the United States, through its intensive use of nitrogen fertilizer, has contributed to nitrate accumulation in groundwater. Concern over this contamination has led to increased public interest in schemes designed to reduce nitrate leachate from agricultural lands. This research compares the costs of alternative regulatory policies in an area of the Com Belt with those for an area of the Northeast. The bioeconomic models of agricultural production and nitrate leaching are used to compare alternative policy instruments. They include soil-specific leaching and productivity characteristics, variables for management response, the dynamic nature of nitrogen movement through the soil, and the stochastic influence of precipitation on...

Autores: Tanguay,   Mark; Adamowicz,   Wiktor L.; Boxall,   Peter C.
The purpose of this study was to identify the values Saskatchewan residents place on their Woodland Caribou conservation programs. Using contingent valuation methods, individual values for maintaining caribou numbers within Millar Western-NorSask Forest Management Licence agreement area were estimated. Using these value estimates, societal benefits were estimated for the implementation of a woodland caribou maintenance program within the forest licence agreement area. The data used in this study were collected using a mailout survey to Saskatchewan residents. Two contingent valuation formats were used, the opened ended willingness to pay and the dichotomous choice. A number of question structures were employed in order to judge the sensitivity of the...

Autores: Garrett,   James L.
This paper synthesizes the strategies put forth at a 2020 workshop on Latin America held in Cali, Colombia, in March 1995, which looked at ways to eradicate extreme poverty, hunger, and malnutrition by 2020; to distribute  income more equitably; and to protect natural resources and the environment. The workshop participants concluded that today's freer economic environment       and reduced barriers to trade will help Latin America to achieve this vision,  provided the region makes full use of its resources and promotes social objectives. A strong food and agricultural system is essential to reach these goals.

Gender Differences In Agricultural Productivity: A Survey of Empirical Evidence
Provedor de dados: 31
Autores: Quisumbing,   Agnes R.
This paper reviews the econometric evidence on gender differences in agricultural productivity. It provides a methodological overview and a critique of (1) production function-based estimates of technical and labor productivity differences by gender, (2) individual (gender-disaggregated) labor supply and earnings functions and (3) studies of the determinants of technological adoption. The review finds that (1) in general, male and female farmers are equally efficient as farm managers. Women farmers' lower yields are attributable to lower levels of inputs and human capital than men. However, the use of coefficients estimated from these studies for simulation exercises may not be valid if endogenous input choice is not considered; (2) returns to schooling...

A consumer-oriented survey at eighteen independently owned garden centers in North Carolina focused on why consumers selected a particular garden center and why they purchased the particular products they selected. Results indicate that potential customers are looking for garden centers that offer good quality plants, a wide selection of plant material, a knowledgeable sales staff, and a convenient location. There is also evidence that most shopping trips are planned and garden centers may be losing potential sales.

EMPLOYMENT HISTORY AND OFF-FARM EMPLOYMENT OF FARM OPERATORS
Provedor de dados: 31
Autores: Stallmann,   Judith I.; Nelson,   James H.
Employment history affects subsequent choices. Based on their original job choice, operators are divided into farmers and workers. Equations are estimated to determine their probabilities of working off-the-farm. Education increased the probability that workers work off-the-farm, whereas vocational training increases farmers' probability. The probability of working off-the-farm decreases as unearned income increases, and its impact on workers is larger than on farmers. An employed spouse increases the probability that farmers work off-the-farm, but has the opposite impact for workers. Employment density increases the probability that workers will work off-the-farm.

DYNAMIC INPUT DEMAND FUNCTIONS AND RESOURCE ADJUSTMENT FOR U.S. AGRICULTURE: STATE EVIDENCE
Provedor de dados: 31
Autores: Warjiyo,   Perry; Huffman,   Wallace E.
The paper presents an econometric model of dynamic agricultural input demand functions that includes research based technical change and autoregressive disturbances and fits the model to data for a set of state aggregates pooled over 1950-82.  The methodological approach is one of developing a theoretical foundation for a dynamic input demand system and accepting state aggregate behavior as approximated by nonlinear adjustment costs and long-term profit maximization.  Although other studies have largely ignored autocorrelation in dynamic input demand systems, the results show shorter adjustment lags with autocorrelation than without autocorrelation.  Dynamic input demand own-price elasticities for six input groups are inelastic, and the demand functions...

Voluntary Incentives for Reducing Agricultural Nonpoint Source Water Pollution
Provedor de dados: 31
Autores: Feather,   Peter; Cooper,   Joseph C.
Agricultural chemicals and sediment from cropland may reduce the quality of America's surface and ground water resources. The Clean Water Act stipulates that individual States are responsible for controlling agricultural nonpoint source pollution. Most State plans rely chiefly on education and technical assistance to promote the adoption of less polluting practices. Because profitability drives production decisions, these programs tend to be most successful when they promote inexpensive changes in existing practices. This report presents research findings on the success of incentive programs to control agricultural nonpoint source pollution.

Income Equalisation Deposits: Enhancing Farm Viability
Provedor de dados: 31
Autores: Buffier,   B.D.; Metternick-Jones,   M.A.
In this paper it is argued that liquidity is an important determinate of farm viability. This is particularly so with a rural sector which suffers large variations in income and has a business cycle which typically extends for several years. Present tax arrangements, coupled with a desire by producers to minimise tax, means that surplus cash in high income years is mostly invested in further improvements, developments or capital equipment. An enhanced Income Equalisation Scheme could play a significant role as a risk management tool for producers as well as reducing calls for government assistance during periods of adversity. Suggestions are made for improving the operation and delivery of the scheme including amalgamating Farm Management Bonds and the...

Price Transmission and Price Integration in Food Retail Markets: The Case of Kinshasa
Provedor de dados: 31
Autores: Minten,   Bart; Kyle,   Steven C.
Integration of commodity markets in developing countries has received considerable attention because price integration is perceived to be central to the success of food and agricultural policies. Price integration tests are performed in retail markets in Kinshasa (Zaire), i.e. between commodities, among retail markets, and between the wholesale and retail market level. Price transmission is measured by incorporating the co-integration concept into the classical long-run and shon-run market integration test. It is shown that although wholesale prices are input prices for retailers, they lack shon-run integration with retail prices. Differences exist between retail markets which do not reflect services or transponation costs. It is hypothesized that this is...

TRADE AND THE POLITICAL ECONOMY OF AGRICULTURAL POLICY: THE CASE OF THE UNITED STATES PEANUT PROGRAM
Provedor de dados: 31
Autores: Borges,   Robert B.
NAFTA and GATT will dramatically alter regulations protecting U.S. peanut markets and will allow foreign producers considerable access to domestic market. Traditionally, the political economy surrounding peanut policy has been favorable to domestic producers. Rising peanut butter imports, decreasing domestic demand, and possibly the inadvertent effects of domestic policy, ironically implemented to protect domestic producers, have contributed to significant increases in Treasury costs. These increased Treasury costs have dramatically changed the political climate surrounding the peanut program. In this light, the effects of GATT appear manageable; NAFTA may ultimately require major policy reform. Possible alternatives are presented.

'Second-Best' Adjustments to Externality Estimates in Electricity Planning with Competition
Provedor de dados: 31
Autores: Burtraw,   Dallas; Palmer,   Karen L.; Krupnick,   Alan J.
A number of state public utility commissions are using "social costing" methods to consider externalities in electricity resource planning. The most comprehensive and formal method is the use of monetary place-holders in the financial evaluation of new investments and potentially in system dispatch to reflect quantitative estimates of externality values. This approach necessarily must take existing environmental and social regulation as given. Furthermore, regulated utilities face increasing competition from electricity generators outside their service territory who may not be affected by social costing. The lack of universal and uniform social costing places PUC actions soundly in the realm of "second-best policy" and they may have unintended consequences...

Australian Beef Exports: Dead or Alive?
Provedor de dados: 31
Autores: Rutherford,   Arlene.
Northern Australia's live cattle exports to Southeast Asia have increased dramatically in recent years. In Australia's current political environment calling for greater domestic value-adding, the issue of potential trade-offs between Australia's live cattle and slaughtered beef exports are examined. From an investigation into the origins of Australia's live cattle export industry and the production and marketing of beef in Australia's major live cattle importing countries, it is concluded that the two industries supply separate segments of the market. Trade-offs between imported Australian beef and beef derived from imported Australian cattle are not significant issues at present.

Autores: Biasi,L.A.; Bilia,D.A.C.; São José,A.R.; Fornasieri,J. L.; Minami,K.
Com o objetivo de estudar a viabilidade da utilização de turfa e de bagaço-de-cana como substrato para a produção de mudas de tomateiro 'Rio Grande' e maracujá-amarelo realizou-se experimento, cujos tratamentos consistiram de turfa (100%), bagaço-de-cana (100%) e suas misturas em proporções volumétricas de 25, 5O e 75%. O delineamento experimental foi inteiramente casualizado com 4 repetições. A maior quantidade de bagaço-de-cana conferiu maior porosidade e aeração ao substrato, favorecendo a emergência do tomateiro e desfavorecendo a do maracujá-amarelo. Para esta espécie, a emergência foi melhor nos tratamentos com maiores porcentagens de turfa, onde a retenção de água pelo substrato foi superior. Entretanto, a utilização integral de cada um dos...

Autores: Cuzzuol,G.R.F.; Gallo,L.A.; Almeida,M. de; Crocomo,O.J.
Baixos níveis de benziladenina (BAP), baixo potencial de água no meio e baixa umidade condicionada por tampas de algodão foram capazes de inibir a vitrificação de cravo (Dianthus caryophyllus L.) cultivado In vitro, mas essas condições implicaram no baixo desenvolvimento das plantas e da taxa de propagação. Elevados níveis de NH4NO3 demonstraram serem altamente promotores da vitrifícação assinalada pelo alto conteúdo de proteína, enquanto relação inversa foi constatada para altos níveis de CaCl2, aos quais seguiu-se aumento na atividade da peroxidase. Os resultados permitiram estabelecer um protocolo para controle da vitrificação do cravo, constituído de 4,0 g/1 de "Gelrite", 0,5 mg/1 de ácido naftalenoacético (ANA), 0,05 mg/1 de BAP, doses normais das...

Autores: Kava - Cordeiro,V.; Luna - Alves - Lima,E.A.; Azevedo,J.L.
A wild strain of Metarhizium anisopliae, an entomopathogenic fungus, was submitted to three mutagenic agents: gamma radiation, ultraviolet light and nitrous acid. Survival curves were obtained and mutants were selected using different mutagenic doses which gave 1 to 5% survival. Morphological and auxotrophic mutants were isolated. Morphological mutants were grouped in a class with yellow conidia and other with pale vinaceous conidia as opposed to the green wild type conidia. Auxotrophic mutants had requirements for vitamin and aminoacid biosynthesis. More than 58% of the total auxotrophk mutants required proline/aipnine. Gamma radiation showed to be the most efficient mutagenic agent giving 0.2% of auxotrophk mutants followed by ultraviolet light (0.12%)...

Características de latossolos roxos desenvolvidos de rochas alcalinas e básicas de Jaboticabal, SP
Provedor de dados: 63
Autores: Centurion,J.F.; Andrioli,L.; Marques Jr.,J.; Marchiori,D. G.
Comparou-se as características químicas, físicas e mineralógicas de Latossolos Roxos desenvolvidos de rocha alcalina (LRe) e de rocha eruptiva básica (LRd), da região de Jaboticabal, SP. Os resultados indicaram que o LRe apresenta-se num estádio de desenvolvimento, comparativamente, menos evoluído que o LRd, enquanto esse se apresenta com tendência para a maturidade. Os menores teores de argila e ferro total e maiores teores de saturação por bases, Ki e CTC da fração argila apresentados pelo LRe comprovam esta tendência. Conclui-se que a ocorrência de Latossolo Roxo eutrófico no campus da UNESP-Jaboticabal, pode estar associada a participação de rochas alcalinas na sua pedogênese.

Eliminação da produção de bacteriocinas em Erwinia e Pseudomonas fitopatogênicas
Provedor de dados: 63
Autores: Biagi,C.M.R. de; Azevedo,J.L.
Duas linhagens de bactérias fitopatogênicas do gênero Pseudomonas e duas do gênero Erwinia produtoras de bacteriocinas, foram submetidas a diferentes tratamentos visando estimar a estabilidade desse caráter. Houve eliminação da produção de bacteriocinas após tratamento com duas concentrações de brometo de etídio e a porcentagem de eliminação variou com o hospedeiro e com a concentração da droga. Não houve eliminação em temperaturas elevadas e também a preservação da linhagem por três anos em laboratório não causou perda do caráter. A eliminação da produção de bacteriocinas com brometo de etídio sugere que os genes envolvidos tenham localização plasmidiana.

Flutuação das proteínas séricas em vacas primíparas e multíparas no período pré-parto
Provedor de dados: 63
Autores: Machado Neto,R.; Prado,G.V.B.; Bessi,R.; Hattnher,F.L.
O comportamento das proteínas séricas foi avaliado em dois grupos de vacas de leite, 6 primíparas e 6 multíparas, durante as ultimas 6 semanas pré-parto. Para separação da fração protéica foi empregado o método de eletroforese, enquanto para quantificação da proteína total foi utilizado o método de biureto. O sangue, retirado da região coccígea, foi amostrado nos períodos 5, 4, 3, 2, 1 semanas pré-parto e no dia do parto. Os resultados indicam uma queda na concentração da proteína total (p &lt; 0.0001), em função do decréscimo da concentração de imunoglobulina (p &lt; 0.0001), durante o período analisado. A proteína total decresceu de 9,82 + 0,7 g/100 ml, na quinta semana pré-parto, para 7,92 + 0,6 g/100 ml no dia do parto (valor mínimo médio registrado)....

O presente trabalho teve por objetivo avaliar as relações entre fonte de assimilados e grão-dreno, bem como o comportamento de fatores morfo-fisiológicos que limitam o rendimento de grãos em plantas de milho de diferentes ciclos (normal, precoce e superprecoce), cultivadas em semeadura tardia (safrinha), com três densidades (33 mil, 55 mil e 77 mil plantas/ha). Verificou-se a eficiência de híbridos de milho quanto à duração do crescimento e rendimento, nas fases vegetativa e reprodutiva. Os rendimentos em grãos variaram entre os híbridos e entre as densidades e foram significativamente superiores nas maiores densidades de cultivo, para os três híbridos avaliados. Valores máximos de índice de área foliar, dentro de híbrido, resultaram em maiores rendimentos...

Poliaminas na embriogênese somática em cenoura (Daucus carota L.)
Provedor de dados: 63
Autores: Schons,J.; Brasil,O. G.
As poliaminas, putrescina (put), espermidina (spd) e espermina (spm) são amplamente distribuídas na natureza, desempenhando importante papel em vários eventos celulares. Considerando que as poliaminas estão envolvidas no processo embriogênico, torna-se importante conhecer as bases para estas alterações no metabolismo. O objetivo do presente trabalho foi observar os teores de poliaminas durante as diferentes fases da embriogênese somátka da cenoura. As análises foram realizadas, através da modificação do método de Flores e Galston a cada 96 horas durante 50 dias da cultura de células em suspensão. As células foram obtidas a partir de calos e inoculadas em meio de Murashige &amp;amp; Skoog (MS), modificado e acrescido de 0,2 mg/l de 2,4-D e 0,1 mg/l de...

Provedor de dados: 63
Autores: Oliveira,F.C.; Marques,M.O.; Bellingieri,P.A.; Perecin,D.
O presente trabalho foi realizado em condições de casa-de-vegetação com o objetivo de avaliar os efeitos da aplicação de doses de lodo de esgoto (equivalentes a 0, 5, 10 e 20 t/ha), complementadas ou não com nitrogênio e/ou potássio, sobre parâmetros de fertilidade do solo, absorção de macronutrientes e produção de matéria seca por plantas de sorgo granífero (Sorghum bicolor L. Moench.) cultivadas em Latossolo Vermelho Escuro. De maneira geral, foi possível observar que o lodo de esgoto, através de sua decomposição no solo, liberou nutrientes para as plantas, refletindo no aumento da produção de matéria seca. Entretanto, visando-se atender às necessidades da cultura, fez-se necessária a complementação com potássio.

Tolerância à salinidade em feijão (Phaseolus vulgaris L)
Provedor de dados: 63
Autores: Broetto,F.; Lima,G.P.P.; Brasil,O.G.
Uma das aplicações das técnicas da cultura de tecidos no melhoramento é a identificação de linhas de células que apresentam tolerância à salinidade. Vários autores obtiveram linhas de células tolerantes ao estresse salino; e estudo de mecanismos bioquímicos da tolerância a sais em plantas tem demonstrado altas correlações entre estes e o acúmulo de macromoléculas em tecido de plantas superiores. Para verificar essas correlações em feijão (Phaseolus vulgaris cv IAC carioca), calos oriundos de eixos embrionários foram cultivados em meio sólido, suplementado com NaCl nas concentrações de 0 a 60 mM. Após 13 dias de incubação, os calos foram coletados e analisados quanto ao crescimento relativo, teor de proteínas, teor de prolina e atividade da peroxidase. Os...

Autores: Hebling,S.A.; Silva,W.R. da.
Foram estudados os efeitos do ultra-som de baixa intensidade (230 e 1750 W/m²) sobre o desempenho de sementes de milho (Zea mays L.) utilizando situações variáveis quanto à disponibilidade hídrica. A emergência e o desenvolvimento de estruturas embrionárias reagem proporcionalmente à disponibilidade de água, não havendo influência marcante do tratamento com ultra-som nos fenômenos envolvidos na germinação das sementes. Contudo, são detectáveis tendências indicadoras de interferência positiva desse tratamento no desenvolvimento das plántulas em situações de deficiência hídrica.

Foi conduzido em casa de vegetação um experimento com o objetivo de avaliar o efeito de fontes de enxofre, na presença ou não de aditivos (uréia e glicose), sobre a absorção do demento pelas folhas de feijoeiro. Os tratamentos: soluções de ácido sulfúrico e de sulfates de amonio, potássio, magnésio, manganês e zinco marcadas com 35S, contendo ou não os aditivos, foram aplicados ao primeiro trifólio das plantas para avaliar a absorção e translocação de enxofre. Os resultados permitiram concluir que 33% do S adicionado foi absorvido, e desse total 27% foi translocado, não havendo influência dos aditivos sobre esses processos.

Autores: Vitti,D.M.S.S.; Abdalla,A.L.; Lopes,H.O.S.; Pereira,E.A.; Meirelles,C.F.
To evaluate non-conventional phosphorus sources, a group of 400 Nellore cows mantained under pasture received a mineral mixture with different P sources (group I: superphosphate - 500 ppm P; group II: superphosphate - 340 ppm P plus rock phosphate Patos 160 ppm P; group III: superphosphate 340 ppm P plus dicalcium phosphate 160 ppm P; group IV - dicalcium phosphate 500 ppm P). There were no differences in pregnancy rate, calving rate and calving interval. A fluorine deposition in bone was observed for the treatments with superphosphate and rock phosphate (66.92 ± 15.53; 69.97 ± 6.5 and 64.05 ± 3.35% respectively for group I, II and III). Superphosphate was almost as good dicalcium phosphate to provide phosphorus for grazing cows and there was a potentially...

Daily rainfall variability at a local scale (1,000 ha), in Piracicaba, SP, Brazil, and its implications on soil water recharge
Provedor de dados: 63
Autores: Reichardt,K.; Angelocci,L.R.; Bacchi,O.O.S.; Pilotto,J.E.
Daily rainfall variability at a local scale (1,000 ha) was studied at Piracicaba, SP, Brazil, for the period of one year (1993-1994), in order to better understand the process of soil water recharge. Coefficients of variation of daily data for ten observation points varied from 2.2 to 169.3% and the variability was independent of rain type, i.e. whether convective, frontal or of other origin. Data were not related to separation distances between observation points and it is concluded that one observation point does not represent areas as far as 1,000 to 2,500 m apart, for daily, monthly or even quarterly averages. Yearly totals for the ten observation points presented a coefficient of variation as low as 3.06%, indicating that all points can replace each...

Effects of light on the propagation and growth of bulbs of Hippeastrum hybridum cv. Apple Blossom (Amaryllidaceae)
Provedor de dados: 63
Autores: Stancato,G.C.; Mazzafera,P.
Commercially bulbs of Hippeastrum hybridum are propagated by twin scales, which are cultured in wet vermiculite in the darkness until bulbil appearance. We showed that twin scales kept under sun light produced bulbils, that once transferred to the field, did not undergo severe light stress. They had higher bulb dry weight and due to the presence of green leaves they grew faster when transplanted to the field than bulbils produced from scales kept in the darkness. An intermediary treatment (a period of darkness followed by transference to light) confirmed the advantages of producing bulbils under sun light conditions. It appears that in the field, growth of bulbs from dark grown bulbils was retarded due to the strong competition among leaves and roots for...

Autores: Stefanutti,R.; Malavolta,E.; Muraoka,T.
O trabalho compara a recuperação do P2O5 residual através de cultivos sucessivos em um solo que recebeu doses crescentes de um termofosfato magnesiano com diferentes granulometrias e superfosfato simples granulado. Os resultados obtidos pela determinação do P extraído pelas plantas em 7 cultivos em vaso permitem concluir que o termofosfato na forma pó, apresenta efeito residual semelhante ao do superfosfato simples granulado; a granulometria mais grosseira do produto termofosfato resultou em menor recuperação do fósforo residual.

O presente trabalho teve por objetivo a apresentação de um modelo iterativo para utilização em microcomputadores capaz de estimar valores de evapotranspiracão de referencia em diversos níveis de probabilidade, a partir de uma série de dados. O procedimento matemático envolvido na técnica iterativa empregada relaciona-se à utilização das funções de densidade gama incompleta e beta. Para tanto, foram utilizados dados quinzenais de evapotranspiracão do mês de março, a partir de uma série de 30 anos para a região de Piracicaba-SP. Através do teste de Kolmogorov-Smirnov, verificou-se que dados estimados através do modelo apresentaram alto grau de ajuste com dados relatados em literatura, justificando assim sua utilização.

Using termite nests as a source of organic matter in agrosilvicultural production systems in Amazonia
Provedor de dados: 63
Autores: Batalha,L. S.; Silva Filho,D. F. da; Martius,C.
The growth of two annual crops, okra (Abelmoschus escutentus) and egg-plant (Solatium melongena) and one perennial crop, andiroba (Carapa guianensis, a native forest tree of Amazonia) under different treatments with organic manure derived from termite nest material of wood-feeding Nasutitermes species was tested (randomized block design). The use of 25-100 g of nest material gave no significant increase in okra productivity, and 25-200 g gave no significant response in andiroba. The combined use of NPK with 200 g of nest material gave a significant higher production in egg-plant (total number and total fresh weight of fruits) when compared to the control (without fertilizer) and to the treatment with NPK only.The results suggest the possibility to use...

Clones de seringueira (Hevea spp ) são enxertados sobre porta-enxertos oriundos de sementes de ascendência desconhecida e por isto não exteriorizara todo seu potencial genético de produção de látex. A superação desta dificuldade pode ser obtida com o enraizamento de estacas clonais. Todavia, a seringueira é considerada em seu estágio adulto como uma planta de difícil enraizamento. Estas plantas possuem na base do caule um cilindro quase contínuo de tecidos lignificados, que juntamente com barraras químicas podem dificultar o enraizamento. Atualmente, algumas plantas de difícil enraizamento, têm enraizado com a ajuda de um conjunto de técnicas modernas como estiolamento total ou localizado e estrangulamento.

Reproductive behavior of Cycloramphus dubius Miranda-Ribeiro (Amphibia, Anura, Leptodactylidae)
Provedor de dados: 104
Autores: Giaretta,Ariovaldo A; Cardoso,Adão J.
Cycloramphus dubius Miranda-Ribeiro. 1920 is a frog species from the coastal Atlantic Forest in Southeastern Brazil. It uses waterfalls of forested rivulets as breeding sites. The eggs are placed outside of water, between rock crevices or roots constantly wetted by water dripping. Clutches have about 60 eggs, and the tadpoles grow attached to rocks, out of water. Males of this species exhibit parental care, biting and/or pushing away strange objects approaching the egg masses. Two types of calls were identified in the spectrograms. The "advertisement calls" consist of juxtaposed pulses lasting 200ms; the "aggressive calls", also have the short pulses structure, and last around 300ms. The aggressive calls are emitted during territorial invasion.

Provedor de dados: 104
Autores: Bombonato,Maria T. Siqueira; Gregório,Elisa A.
Hemocytes of Diatraea saccharalis larvae aging from 13 to 26 days old were morphological and quantitatively characterized by phase contrast microscopy. Six hemocyte types were described and identified as: prohemocytes (PR), plasmatocytes (PL), granulocytes (GR), oenocytoides (OE). spherulocytes (SP) and verm cells (VE). The total hemocyte counts showed no significant difference in the number of these cells along the normal development of the larvae. However, the relative number of different circulating hemocyte types fluctuated, and it could be expressed as: PL &gt; GR &gt; SP&gt; PR &gt; VE &gt; OE in larvae up to 14 days old; and as: GR &gt; SP &gt; PL &gt; VE &gt; OE &gt; PR in those older than 24 days.

Autores: Lopes,Benedito C.
A survey on the use of host plants by treehoppers in plants in cerrado (savanna) vegetation at Moji-Guaçu (São Paulo, Southeastern Brazil) was made. Fifty-two species of treehoppers were recorded in association with 40 host plant species from October 1980 to February 1982. The families Araliaceae, Asteraceae, Leguminosae, Malpighiaceae, Myrtaceae and Nyctaginaceae were the most commonly used for oviposition. Byrsonima intermedia A. Juss. (Malpighiaceae) had the highest number of associated treehopper species (10 species). The abundance of treehopper individuals was related to the hot and rainy season (from October to February), while during the cold and dry season (from March to September) there was a decrease in the number of these Homoptera. After the...

A simple net trap for capturing agile porcelain crabs living amongst superposed stones of the midlittoral rocky shore was developed. About a hundred pebbles and boulders were dislodged from I m² area and Im depth, so that a pit was formed. A sheet net of Im² and Imm mesh size was spread on the bottom of this pit and the stones were replaced again, like the original condition. After a cicle of high tide (about 12 hours), the same stones in the pit were carefully searched by dislodging and by rinsing them. The porcelain crabs were slowly getting out from the handling stones towards the bottom until they found the net sheet. The net border was lifted and the animais captured.

From 1978 to 1991, 48 bird species have exploited some kind of resource in a residential quarter reasonably well provided of vegetation. There was a predominante of species with generalist feeding habits (omnivores and non-specialized insectivores), forest edge or secondary growth dwellers, and species that feed and nest in arboreal and shrub layers. Only 23 species are certain or probable residents; the presence of others is due to migration or to displacement of populational excedents coming perhaps from nearby urban parks. Although the vegetation is not exactly profuse, it is enough to be exploited by many forest species. As the city of São Paulo confines with the Atlantic Forest, this kind of urban vegetation may be important to the maintenance not...

The aim is to determine the relationship between the diversity of small mammals and the structural heterogeneity and/or secondary successional stages in an Atlantic forest fragment at Viçosa (Minas Gerais). We used Sherman and hook live traps to sample this fauna, monthly from may 1992 to april 1993 in three areas: an abandoned plantation of Melinis minutiflora (campo) and two distinct forest areas (capoeira and mata). The structural heterogeneity was determined as a function of the presence of dead trees, pioneer species, epiphytes, the distances between trees, the tree height and basal area measured by a modified quadrant sample method (Cottam &amp;amp; Curtis 1945). lt was sampled a total of 340 individuals belonging to 17 species.

The fauna of Euglossinae bees were studied in two areas of "terra firme" continuous forest in the Central Amazon. Brazil. During one year (september/1989-august/1990) the collections were done fortnightly, using traps with eight kinds of seents baits. The traps were placed in the understory and in the tree crowns. The continuous forest of "terra firme" near Manaus are among those with the highest speeies richness of Euglossinae in the Neotropics. The species richness was higher than that found in other studies carried out in Brazil also. One study area had higher species richness and abundance, while species diversity was higher in another one. The diversity was different significally between the two areas.

Bairdiella ronchus is one of the most common species of demersal ichthyofauna in Guaratuba Bay, south Brazil. However, this study reveals that is does not inhabits permanently the mangroove area. Individuals with more than 94mm total lenght leave mangroove area in late summer and early auntumn and returming in the spring. when they start ovarian veitellogenesis. During late spring and early summer, the oocytes are hydrated, and empty follicles can be found in the ovaries, indicating that this is the reproductive time for this species As other Sciaenidae. B. ronchus is a multiple spawner species.

The ocurrence of males, gamic and ambiohasic females of the greenbug Schizaphis graminum (Rondani, 1852) among parthenogenetics reared on Sorghum bicolor (Linnaeus) Moench, in Ribeirão Preto (São Paulo, Brazil), from 1980 through 1983, follows an annual cycle. They appear from April through June, when the photoperiod has about 11 hours of daily photophase. Despite the low number these findings support the potential for holocycle, triggered by variable abiotic factors in this region with mild winters.

Autores: Pires,Ana Maria Setubal.
Three species of janirid isopods were found on the sea star Echinaster brasiliensis Müller &amp;amp; Troschel collected in São Sebastião Channel, southeastern Brazil. Janaira gracilis Moreira &amp;amp; Pires and Carpias nereus (Pires) were previously known from the area and Carpias asterophilus, sp.n. is described. The three isopod species were found together on the dorsal surface of the sea star, and juveniles performed nearly 73% of the population. The janirids presented homeochromy with the sea stars, and food and shelter were the observed benefits that the crustaceans received from the association. A key to separate the species of Carpias with a spoon-like gnathopod is included.

Autores: Rego,Amilcar Arandas.
The morphology, ontogeny, life-cycles and distribution of species of the Order Proteocephalidea (Cestoda), is discussed. A brief historic of the classifications is presented. The actual scheme of taxonomy of WOODLAND (1924-1935) is criticicized and a new classification for the group is proposed. The phylogenetic uniformity of Proteocephalideans is reestablished with this classification. The genera of Monticelliidae (sensu Woodland) are transferred to the subfamilies Proteocephalinae and Corallobothriinae. Only one family is accepted in the Proteocephalidea. Proteocephalidae La Rue. 1911: with five subfamilies: Proteocephalinae. Corallobothriinae. Sandonelliinae. Gangesiinae and Acanthotaeniinae.

A quali-quantitative survey of avifauna was earried out at the Santa Genebra forest reserve (MSG) in order to evaluate the current state of conservation of this important conservation area in the interior of São Paulo Stale. The qualilative survey recorded 134 species and the quantitativo survey through unlimited distance point counts recorded the abundance of 97 species. The low number of species recorded in both surveys was due to the small size (251 ha) and the high degree of isolation of the MSG. These factors plus the extensivo degradation of the forest cover prevent recolonization of extinct species and allow the expansion of some species tolerant to disturbance. The quantitative survey showed some species with an unusually high abundance index. The...

It has heen responsible for the majority of deaths of captive animals. Twenty-six marked wolves have been followed in the field with ear-tags and radio-collar tagged (Tab. II) to investigate their interactions with the environment, their diurnal shelters, movements and habits, and their delivery sites. Ten years of life history data have heen gathered. They are territorial and monogamous, and give birth to two or three young once a year, after a 63 days gestation, on average. Maned wolves inhabit the open areas and have omnivorous feeding habits.

Morphological study of the testes of the dove Columba livia (Gmelin) (Columbidae, Columbiformes)
Provedor de dados: 104
Autores: Maruch,Sandra Maria das Graças; Teles,Maria Eloiza de Oliveira; Ribeiro,Maria das Graças.
Known as "domestic dove", the Columba livia (Gmelin, 1789) is a columbidae species widely distributed in Brazil, whose reproductive biology has been studied by many researchers. The testes of 12 Columba livia males were collected and prepared for histologic examination under an optical microscope, the results of which were analysed and photographed. The tunica albuginea that covers the testes consists of a thick, not very cellular layer of dense connective tissue. Groups of interstitial cells with typical morphological appearance and surrounded by loose, well vascularized connective tissue are observable within the organ, between the seminiferous tubules. The seminiferous tubules are thick, intensely wound and, when seen in cross section, show Sertoli...

CONTRIBUIÇÃO AO CONHECIMENTO DO SISTEMA RADICULAR DA PUPUNHEIRA (Bactris gasipaes KUNTH, PALMAE). II. SOLO LATOSSOLO AMARELO, TEXTURA ARGILOSA
Provedor de dados: 36
Autores: FERREIRA,Sidney A. do Ν; CLEMENT,Charles R; RANZANI,Guido; COSTA,Suely de S.
A distribuição da biomassa e da área absorvente do sistema radicular da pupunheira (Bactris gasipaes)foram estudadas num latossolo amarelo, textura argilosa, perto de Manaus, Amazonas, Brasil. Aproximadamente 80% da biomassa se encontrava no horizonte Ap, da qual 90% se encontrava dentro da área de projeção da copa. A biomassa total estimada pesou 72 kg, excluindo-se a massa logo abaixo do estipe. A área superficial das raízes aumentou significativamente conforme se afastava do estipe, devido a proporção cada vez maior de raízes terciárias e quartenárias, embora sua abundância por m3 diminuiu de forma similar à biomassa. A área superficial total estimada chegou a 545 m2, da qual se supõe que 50% é ativa na absorção de nutrientes. Supõe-se ainda que existam...

São descritos aspectos morfológicos e estruturais dos frutos e sementes, em desenvolvimento, de Platonia insignis(Clusiaceae), visando principalmente esclarecer a origem da camada comestível presente no fruto. Concluiu-se que a camada carnosa branco-amarelada, que envolve as sementes, é de origem endocárpica e começa a se diferenciar já nos estádios iniciais do desenvolvimento do fruto, através de um acentuado alongamento radial das camadas mais internas do endocarpo. Estas, juntamente com as células dos septos, que também se alongam à medida que o fruto se desenvolve, vão se aderindo à testa por meio de interdigitações. Posteriormente, no fruto maduro, o endocarpo destaca-se do restante do pericarpo, permanecendo firmemente ligado à semente.

Seedling morphology was studied in Campa guianensisAubl. and Carapa proceraD. C. from germination to 90 days age. In both species germination is hypogeal and cryptocotylar. Both have rare albino seedlings. Though both species have compound leaves when adult, C, proceraputs out an average total of six simple leaves at germination, while leaves of C. guianensisare compound at all stages. This is the best diagnostic character for separation of the two species at the young seedling stage. Not diagnostic, but none the less useful, is the fact, that polyembryonic seeds are often found in C. procera,but not observed in C guianensis.

O cupuaçu (Theobroma grandiflorum,Sterculiaceae) é uma frutífera da Amazônia usada na fabricação de sucos, sorvetes, doces e chocolate. A sua popularidade vem aumentando e atualmente é considerada uma das culturas mais lucrativas da região Amazônica. O cupuaçu é uma espécie predominantemente alógama e muitas flores não chegam a dar frutos mesmo quando polinizadas com póíen compatível. A taxa de polinização natural é baixa (estimado em 1,6% para pístílos polínízados com mais de 60 grãos de pólen). No presente trabalho, foram estudados alguns aspectos da sua polinização. Polinizações manuais foram feitas próximo à antese (entre 17-18:00 h) e na manhã seguinte após a antese, da seguinte maneira: retiraram-se três estaminódios da flor que iria ser polinizada...

De 40 folhas de plantas de cupuaçu com 2,5 meses de idade, foram medidos: área de cada folha, peso da folha fresca, peso do limbo fresco, comprimento da folha, comprimento do limbo, maior largura do limbo, distância da base do limbo até a sua maior largura e o peso da folha seca. Entre essas variáveis, com o uso da análise de regressão por passos (stepwise), foram obtidas equações de regressão para estimar a área da folha e o peso da folha seca. Com a equação obtida para a determinação da área da folha (log da área da folha = -0,133 + 1,095 log Comprimento do limbo + 0,872 log Largura do limbo R2= 0,996), conseguiu-se que 92,5% dos dados calculados apresentassem desvios menores do que 10% do valor observado. As equações testadas para a determinação do peso...

CTENOCHAETUS MARGINATUS (VALENCIENNES) (PISCES: ACANTHURIDAE) EN LA ISLA DE GORGONA: PRIMER REGISTRO DEL GÉNERO PARA EL PACÍFICO COLOMBIANO
Provedor de dados: 50
Autores: Zapata,Fernando A.; Morales,Yaneth A.
The genus Ctenochaetus is reported in the waters of the Colombian Pacific based on two specimens of C. marginatus (Valenciennes) collected in 1993 at Gorgona Island (2°59' N, 78°12' W). These specimens differ in several morphometric characteristics from those previously examined. Such differences appear to be an artifact of the small number of specimens formerly examined and the consequent narrow ranges reported. We suggest that temperature variability affects the distribution of C. marginatus in the tropical eastern Pacific.

Mytilopsis sallei es una especie que se encuentra ampliamente distribuida sobre sustratos duros en la Ciénaga Grande de Santa Marta, siendo particularmente abundante sobre bancos de ostra de mangle (Crassostrea rhizophorae), donde alcanza densidades de hasta 5000 indiv/m². Aunque posee una amplia tolerancia a variaciones en la salinidad y temperatura, prefiere aquellos lugares donde la afluencia de aguas dulces es constante. Puede además tolerar aguas turbias con un alto contenido de sedimentos, como en la desembocadura de los ríos. M. sallei no parece aparentemente, competir con la ostra, incluso en aquellos bancos sometidos a intensa explotación. Esto se debe a las preferencias ambientales de cada especie y a la alta productividad de las aguas de la...

BENTHIC COMMUNITIES AND GEOMORPHOLOGY OF THE TESORO ISLAND CORAL REEF, COLOMBIAN CARIBBEAN
Provedor de dados: 50
Autores: Sánchez M.,Juan Armando.
The benthic communities distribution in Tesoro Island (Colombian Caribbean) coral reef was determined by cartography of reef morphology and functional groups from aerial photographs, theodolite triangularon, and bottom transects over depths ranging from 0 to 30 m. Tesoro Island is a sand cay reef developed over an emerged reef platform whose basal cone possibly originated by mud diapirism on the continental shelf. The benthic communities are distributed as subzones of the geomorphologic units. The reef crest lies along the breaker zone, formed by Millepora spp. buttresses covered on their tops by Palythoa spp. and seawardly by a turf of Dictyota spp. The rear reef (varying from 0.5-1.5 m in depth) is composed of pavement and grooves with live Porites...

SUCCESSIONAL PATTERNS ON FOULING PLATES IN THE BAY OF SANTA MARTA, COLOMBIAN CARIBBEAN
Provedor de dados: 50
Autores: Garcia,Camilo B.; Salzwedel,Horst.
Successional progress was followed in fouling communities, developing under tropical conditions. Primary succession was simulated by immersing asbestos plates. The plates represent small, discrete, isolated parts of habitat. According with expectations, a trend of increasing space dominancy by colonial forms was detected as succession progressed. High within-habitat diversity but global persistency was confirmed for this tropical system. Several mechanisms of succession were found to operate simultaneously. In this Caribbean fouling system thestrong self-replacement tendencies of solitary forms and the low recruitment and growth rates of the potential space dominants (colonial forms) were mostly responsible for the successional patterns observed.

A necessidade da discriminação de cultivares de arroz determinou o estudo das características físicas, fisiológicas e químicas das sementes e plântulas. Selecionaram-se as técnicas pelos seguintes fatores: precisão, reprodutibilidade, simplicidade, rapidez e custo de execução. Todas as características morfofisiológicas das sementes e plântulas foram de grande utilidade na diferenciação dos cultivares; na maioria das vezes, o conjunto de diferentes características é que permitiu uma discriminação segura. A coloração pelo fenol e a técnica de eletroforese utilizadas não foram eficientes na discriminação dos cultivares.

Sítios de penetração do quinclorac em sementes e plântulas de pepino e capim-arroz
Provedor de dados: 53
Autores: Amarante,Luciano do; Lopes,Nei Fernandes.
Experimentos realizados em casa de vegetação ou em laboratório, em Viçosa (MG), visaram determinar os sítios preferenciais de penetração do quinclorac em sementes e plântulas de Echinochloa spp. e Cucumis sativus L. cv. Caipira AG 221. O quinclorac foi eficientemente absorvido por semente, radícula, coleóptilo ou hipocótilo do capim-arroz e do pepino. As maiores reduções no alongamento e na massa seca do sistema radicular e aéreo ocorreram quando o herbicida foi absorvido por radículas, em ambas as espécies, indicando ser o sítio preferencial de penetração em estruturas jovens. O quinclorac produziu sintomas visuais de fitotoxicidade ou alterações morfológicas nas plantas tanto de pepino quanto de capim-arroz.

Autores: Rosier,Jean Pierre; Carbonneau,Alain.
Este trabalho avalia a influência de dois sistemas de condução (lira e espaldeira) e do tipo de solo (arenoso e argiloso) no crescimento do aparelho vegetativo da videira. As diferenças observadas foram maiores no crescimento dos netos do que no dos sarmentos e estão ligadas à precocidade determinada pelo tipo de solo. Os efeitos da poda verde e do estresse hídrico associados aos sistemas de condução foram os responsáveis pelas diferenças na velocidade de crescimento dos sarmentos e dos netos.

Autores: Pommer,Celso V.; Ramming,David W.; Emershad,Richard L.
Eighteen seedless grape genotypes differing in ripening season (early, mid and late) and in seed trace size (small, medium and large) were harvested at 6, 10, 14, 18 and 22 weeks past bloom (wpb). Using embryo rescue techniques it was studied if embryo do abort as the fruit matures and what percent embryos remain viable at later stages. The size of seed trace was also investigated to determine its influence on embryo viability during maturation. It was found that genotype have great influence on embryo culture traits. Late maturing genotypes showed fewer rescued embryos, germinated embryos and transplantable plants than early and mid season ones. The best culture time for grape embryo rescue is 6 and 10 wpb. At these dates, the largest number of embryos,...

Em latossolo roxo, ácido e de baixa fertilidade, do município de Guaíra (SP), implantou-se, em 1976, um ensaio permanente de calagem e adubação potássica com o algodoeiro, variedade IAC 18. Em esquema de parcelas subdivididas, o calcário dolomítico foi incorporado às parcelas nas doses de 0, 2, 4 e 6 t/ha no primeiro ano. O potássio foi aplicado anualmente, nas doses de 0, 50, 100 e 150 kg/ha de K2O, na forma de cloreto e na presença de doses constantes de N, P2O5 e, quando necessário, boro. No sexto ano (1981/82), reaplicou-se o calcário nas doses originais e, nos anos subseqüentes até 1985/86, utilizou-se a variedade IAC 20. No primeiro ciclo de calagem, o calcário alterou positivamente a massa de um capulho e deprimiu a de cem sementes. Ambas as...

Desenvolvimento do sistema radicular da soja em sucessão à crotalária
Provedor de dados: 53
Autores: Tanaka,Roberto Tetsuo; Mascarenhas,Hipólito Assunção Antonio.
A obtenção de elevada produtividade agrícola depende, entre muitos fatores, do bom desenvolvimento radicular das plantas. Neste trabalho, investigaram-se as causas das diferenças no desenvolvimento do sistema radicular da soja, cultivada em duas glebas adjacentes de um mesmo tipo de solo, sendo uma implantada em semeadura direta em sucessão ao cultivo da crotalária (Crotalaria juncea L.) e a outra, em sistema convencional de manejo do solo. As variáveis analisadas indicaram que: (1) a partir de 10 cm até a profundidade estudada de 120, a gleba com manejo convencional mostrou melhores condições químicas para o desenvolvimento das plantas; (2) as concentrações de fósforo, potássio e cálcio da parte aérea das plantas de soja cultivadas tendo como substratos...

Encontrou-se, anos atrás, em uma lavoura de Coffea arabica (2n = 44), uma forma de café bastante distinta das demais. Inicialmente, julgou-se tratar de um cafeeiro autotetraplóide de C. liberica (2n = 22) ou de C. dewevrei (2n = 22). Estudos morfológicos e citológicos de tal cafeeiro, denominado Piatã (prefixo C387 da Seção de Genética do IAC), assim como de seus descendentes, indicaram tratar-se, provavelmente, de um híbrido natural derivado da união de um gameta normal de C. arabica e de um não reduzido de C. dewevrei. No presente trabalho, os estudos dos padrões eletroforéticos das enzimas PGI, PGM e ADH do endosperma de sementes confirmaram a origem interespecífica do café Piatã. A combinação de alelos dessas enzimas é distinta e específica para C....

Tratamentos com fungicidas no comportamento de sementes de amendoim
Provedor de dados: 53
Autores: Maeda,Jocely Andreuccetti; Lago,Antonio Augusto do; Gerin,Marcelo Aparecido Nunes.
As sementes de amendoim (Arachis hypogaea L.) são especialmente vulneráveis à invasão fúngica, causa freqüente de estandes insatisfatórios e, conseqüentemente, de baixas produções da cultura. A eficiência dos fungicidas Captan, Thiram (TMTD), Benomyl, Quintozene (PCNB) e Thiabendazole, aplicados em sementes de amendoim do cultivar Tatu, foi estudada com relação à emergência de plântulas em casa de vegetação, e à emergência inicial, ao estande final e à produção de vagens no campo. Em todos os parâmetros, não houve efeito de época nem de interação fungicida x época de aplicação. A vantagem do uso de fungicida ficou bem evidenciada, uma vez que as sementes tratadas apresentaram, em relação às não tratadas, emergência de plântulas superior em casa de...

Autores: Queiroz-Voltan,Rachel Benetti.
Estudaram-se as alterações anatômicas em plantas de algodoeiro com sintomas de murchamento avermelhado em dezembro de 1993-fevereiro de 94. Analisaram-se amostras de raiz, caule e folha de Gossypium hirsutum L. 'IAC 20' provenientes de áreas de ocorrência do sintoma. Estimou-se o número de glândulas secretoras das folhas dos cultivares IAC 20 e CNPA ITA 90 (que se tem mostrado resistente). Observou-se que as células parenquimáticas apresentavam, no interior, substâncias insolúveis em água, cuja concentração aumentava à medida do grau do sintoma. As folhas apresentaram uma concentração maior dessas substâncias em relação ao restante do corpo vegetal. Os núcleos das células do parênquima paliçádico encontravam-se aumentados e os cloroplastos do mesofilo,...

Estimativa do tamanho ótimo de parcelas experimentais através de cálculos algébricos
Provedor de dados: 53
Autores: Barros,Inácio de; Tavares,Marcelo.
Este trabalho visa estabelecer um método que propicie a determinação do tamanho ótimo da parcela experimental, determinando o ponto de máxima curvatura por meio de cálculos algébricos. Há uma relação entre a variância da parcela e seu tamanho, como também entre o coeficiente de variação da parcela e seu tamanho. Mediante a apresentação e discussão de um exemplo, conclui-se que o método oferece uma solução algébrica para o ponto de máxima curvatura e não leva a interpretações diferentes quando se altera a escala do gráfico. Entretanto, pode apresentar um tamanho de parcela que corresponda a um coeficiente de variação ainda alto, revelando-se, então, desaconselhável.

Objetivando avaliar a adsorção de boro em alguns solos sob vinhedos do cv. Concord, na região da Serra Gaúcha, desenvolveu-se, em 1991, um trabalho a partir de oito amostras onde se adicionaram diferentes concentrações de boro para obtenção da concentração de equilíbrio, determinando-se, através da equação de Langmuir, sua adsorção máxima para cada solo. Os solos estudados apresentaram capacidade de adsorção de boro, no pH original, de 71 a 416 mg/kg de solo. A equação de Langmuir foi mais consistente na descrição da adsorção de boro em quatro amostras das oito avaliadas.

Provedor de dados: 53
Autores: Monteiro,Domingos Antonio; Kanthack,Ricardo A.D.; Peressin,Valdemir A.; Lorenzi,José Osmar; Perecin,Dilermando.
Nas condições do Estado de São Paulo é freqüente o armazenamento de ramas de mandioca (Manihot esculenta Crantz) para aguardar a melhor oportunidade de efetuar o plantio. Utilizam-se os sistemas de empilhamento horizontal e vertical, sendo mais comum o primeiro. Raramente, empregam-se ramas recém-colhidas para plantio. 0 presente trabalho teve por objetivo estudar o efeito do material de plantio em alguns parâmetros fitotécnicos da cultura, em função dos diferentes estádios fisiológicos causados pelo armazenamento ou não das ramas. Num esquema fatorial de 2 x 3, em blocos ao acaso com quatro repetições, utilizaram-se dois cultivares - IAC 12-829 e SRT 1287-Fibra, de alta e baixa capacidade de ramificação respectivamente - e três tipos de manivas,...

Ensaio de longa duração com calcário e cloreto de potássio na cultura do algodoeiro
Provedor de dados: 53
Autores: Silva,Nelson Machado da; Carvalho,Luiz Henrique; Quaggio,José Antonio.
Decorridos cinco anos de um ensaio de calagem e adubação potássica do algodoeiro, em latossolo roxo distrófico do município de Guaíra (SP), reaplicou-se o calcário nas mesmas doses da primeira fase (0, 2, 4 e 6 t/ha). Utilizou-se o calcário dolomítico com 25,3% de CaO, 19,9% de MgO e 68% de PRNT. O potássio foi aplicado em subparcelas nas doses anuais de 0, 50, 100 e 150 kg/ha de K2O, na forma de cloreto de potássio. Fez-se, anualmente, a adubação com N, P2O5 e B nas doses respectivas de 60, 100 e 1,5 kg/ha. O efeito da calagem no aumento dos valores de pH e da saturação por bases da camada arável do solo foi imediato, havendo, no entanto, um decréscimo nos valores desses índices após o segundo ano e um retorno aos níveis da fase anterior....

Variabilidade espacial do potencial de erosão das chuvas do Estado de São Paulo
Provedor de dados: 53
Autores: Vieira,Sidney Rosa; Lombardi Neto,Francisco.
Utilizaram-se dados de 292 pluviômetros da rede oficial do Estado de São Paulo para o cálculo do fator R da equação universal de perdas de solo, segundo modelo disponível na literatura. O objetivo deste trabalho foi usar a geoestatística para estudar a variabilidade espacial do potencial de erosão das chuvas e construir mapas de isolinhas com precisão. Calculou-se a dependência espacial através do semivariograma para os períodos das secas (abril a setembro), das águas (outubro a março) e para a erosividade média anual. Os alcances dos semivariogramas variaram de 50 a 70 km, porém a autovalidação das estimativas mostrou que o número de vizinhos utilizados em uma estimativa não deve ultrapassar 16 para que as hipóteses a respeito dos dados não sejam...

Nesse estudo, realizado em 1992, nos Institutos Agronômico, de Tecnologia de Alimentos e de Zootecnia, procedeu-se à caracterização bromatológica e mineral dos resíduos de broto de bambu (Dendrocalamus giganteus Munro), a fim de utilizá-los como alimento animal. Os resultados mostraram que tais resíduos, constituídos basicamente por bainhas e pedaços tenros de colmo, apresentaram elevados teores de proteína (131,4 g/kg), açúcares (115,3 g/kg), fibras (235,4 g/kg) e ácido cianídrico (213 mg/kg). Essa concentração de ácido cianídrico pode causar efeito tóxico em animais, devendo-se, portanto, eliminá-lo, adotando o mesmo procedimento utilizado para a fração comestível do broto, o qual se resume no cozimento em água fervente durante 20 minutos. Após esse...

Autores: Biasi,Luiz Antonio.
Desenvolveram-se dois experimentos para verificar o efeito do ácido nalidíxico, do cloranfenicol e da estreptomicina sobre a cultura in vitro do abacateiro 'Ouro Verde'. No primeiro, testou-se a influência de diversas concentrações (0, 12,5, 25, 50, 100 e 200 mg/L) desses antibióticos sobre a calogênese de discos foliares e, no segundo, o efeito sobre a brotação de gemas de segmentos nodais. Enquanto a formação de calos foi reduzida à metade com o uso de 50 mg/L de cloranfenicol, sua massa foi drasticamente reduzida já na concentração de 12,5 mg/L. Restringiu-se o comprimento das brotações, adicionando os antibióticos ao meio de cultura, concluindo-se que os três foram tóxicos para o abacateiro, sendo recomendados apenas em casos de extrema necessidade,...

Estudou-se o efeito de vários níveis de compactação na densidade do solo, porosidade total e resistência à penetração, objetivando determinar o nível que impede o desenvolvimento das raízes de plantas de soja. O trabalho foi realizado em casa de vegetação, com amostras deformadas do horizonte superficial de uma terra roxa estruturada e de um latossolo roxo, controlando os níveis de compactação e o teor de água. A influência da compactação no desenvolvimento das raízes foi avaliada um mês após a germinação. Os valores de densidade do solo, para um mesmo nível de compactação, foram maiores para a terra roxa estruturada. O teor de água ótimo para a compactação foi de 21,0% para a terra roxa estruturada e de 29,8 para o latossolo roxo. A compactação artificial...

Lâmina adicional de irrigação
Provedor de dados: 53
Autores: Pires,Regina Célia de Matos; Arruda,Flávio Bussmeyer.
Um dos critérios que podem ser utilizados no manejo das irrigações consiste na aplicação de água sempre que for consumida uma lâmina líquida (h1) prefixada. Dessa forma, a lâmina de irrigação realmente necessária (h1n) para repor a umidade do solo à capacidade de campo será sempre maior ou igual à lâmina h1 inicialmente projetada. Para quantificar esse valor adicional, simularam-se irrigações por meio de balanço hídrico diário, em duas diferentes épocas do ano, com vários valores de h1 para Ribeirão Preto (SP). Analisaram-se as freqüências relativas de h1n comparadas à h1 e calcularam-se as porcentagens adicionais de água (%h a). Os resultados mostraram que à %h a mais importante correspondem a h1 pequena e os valores elevados de evapotranspiração e do...

Autores: Coraggio, José Luis.
El  tema propuesto para esta sesión se refiere a los procesos de descentralización como instrumento para la democratización de la sociedad en el ámbito local. Se trata entonces de pensar la descentralización desde la perspectiva de su instrumentación, no como un objetivo en sí mismo. Por lo tanto, se hace necesario aclarar cuál es el sentido de descentralizar. Es importante dejar esto sentado porque hoy en día coexisten proyectos y procesos de descentralización que se inspiran en motivos o en sentidos distintos, aunque todos usan el mismo termino.

La familia campesina en el período de la violencia. El ejemplo de Paca y Coracora en Ayacucho
Provedor de dados: 122
Autores: Landa Vásquez, Ladislao H.
La década del 80 e inicios del 90 fue uno de los períodos más difíciles para la mayoría de los campesinos ayacuchanos como consecuencia de la violencia política. La presencia de los militares significó represión, secuestros, desapariciones, violaciones de mujeres, robos, etc.; los militantes del PCP Sendero Luminoso por su parte realizaron ajusticiamientos o asesinatos a autoridades y pobladores, tomas de ciudades, reclutamiento voluntario y forzoso de jóvenes, arengas, sabotaje, etc. Este proceso de violencia ha producido también ciertos cambios que parecen ser irreversibles, sus efectos pueden observarse en una serie de variaciones a nivel de la economía campesina, por ejemplo, ha habido un crecimiento inusitado de la aparcería, una agudización de falta...

La globalizaci??n de la econom??a ha tra??do como consecuencia el auge de un estilo de vida utilitario que nos recuerda las ideas de Jeremy Bentham y John Stuart Mili. Pero hay motivos de desconcierto: ??Es la ??tica empresarial del neoliberalismo un aut??ntico renacer de la doctrina cl??sica? ??Ha sido diferente el l??beral??smo europeo del de Am??rica Latina? ??Tiene todav??a alg??n mensaje v??lido ese pensamiento para los que no nos conformamos con un mundo de injusticia social  generalizada?

De hecho, la revoluci??n liberal, abri?? un proceso que se ha desarrollado hasta el presente;gener?? una profunda transformaci??n de la estructura jur??dico-pol??tica del Ecuador, y un haz de relaciones sociales potenciales que se desplegar??an a lo largo de todo el siglo.

Como el surgimiento del nuevo Estado (la relación de éste con los indígenas-campesinos) y la reforma agraria del 53. Particularmente resaltamos la relación de la nueva forma de organización “campesina”: los sindicatos y sus líderes con el "Estado del 52" y el proceso de autonomización. Finalmente~ intentamos un...

Esta investigación analiza la política del Banco Central en su primera década de funcionamiento.

Sus cuatro primeros años de funcionamiento estuvieron fielmente apegados a la ortodoxia determinada por su creador, pero a partir de 1932 la crisis deflacionaria producida por la estricta conjugación de los preceptos contenidos en la Ley de Monedas y en el primer estatuto del Banco Central, a cargo de los personeros de este último, hizo ineludible una radical variación de política. A partir de entonces, cambió la tendencia del nivel general de precios...

El espacio amazónico hay que pensarlo como un producto social que condensa, expresa y crea relaciones sociales. En tanto producto de la acción humana, este espacio no puede ser concebido como un ente independiente. Por el contrario, es la expresión del tipo de relaciones que cada una de las sociedades nacionales ha instaurado con el área. Así por ejemplo, es diferente el espacio amazónico construido por Brasil que el espacio construido por el Perú. Son distintas las concepciones en torno al espacio, las relaciones sociales surgidas en el proceso de ocupación y las maneras como cada una de estas sociedades se ha apropiado de los recursos naturales del área y del excedente del trabajo humano.

¿Ya no hay indios en el Perú?, una investigación sobre el concepto de la etnicidad y la identidad social de los migrantes del sur de los Andes en Lima
Provedor de dados: 122
Autores: Huayhua Curse, Margarita.
Existe en el Perú, particularmente entre los científicos sociales que tratan sobre la realidad social actual de este país, un "acuerdo" relativo a la existencia de una identidad social "chola" como una misma realidad empírica. Este acuerdo, que está muy lejos de ser tomada como una mera tesis sobre los fenómenos socio-culturales que ocurren en este país, según los intelectuales peruanos que trabajan sobre esta temática, estaría probada por procesos específicos como: la migración masiva de "provincianos serranos" a Lima, la urbanización generalizada del país sin industrialización y la "informalización" de la economía. En conjunto, estos procesos sociales habría dado lugar a que la población total del país se haya "cholificado" o estaría "cholificándose".

Las corrientes mundiales de pensamiento han inducido a casi todas las diversas sociedades del orbe, a emprender agresivos procesos de modernización, privatización y simplificación en todas las actividades. La época de las sociedades y revoluciones centralistas vive su ocaso, el crecimiento demográfico en todos los países exige que la población sea atendida con eficiencia y rapidez mediante el ejercicio del poder por organismos cercanos a la población. Dentro de éste proceso son llamados a asumir el rol protagónico los municipios que día a día asumen de manera creciente su papel de gobiernos locales.

Autores: Terrazas Farfán, Norma Jesús.
La realización del estudio de los cambios producidos en el lenguaje político es uno de los medios para entender los problemas que la traducción causó en documentos escritos tempranamente como las crónicas del siglo XVI y las visitas a comienzos del siglo XVII. Los elementos de análisis en este estudio son en sí mismos de lenguaje que luego del proceso de traducción al español y de su registro en escritura por parte de extranjeros permite conocer la transformación del rol de los Kurakas en las épocas inca y colonial en los que esta tesis se enmarca. De igual forma estos parámetros constituyen la base sobre la cual se sustentan estudios relacionados a la sucesión, genealogía, funciones económicas como la producción, distribución y tributación, funciones...

Cuando los montes se vuelven carbón : la transformación de los paisajes en los alrededores de Quito 1860 - 1940
Provedor de dados: 122
Autores: Pérez, Pilar.
En el Ecuador durante siglos los cambios en el paisaje agrario se dieron de manera paulatina, casi imperceptibles, a penas visibles. A finales del siglo XIX y en las primeras décadas del siglo XX las técnicas de producción y los principios consuetudinarios que reglan el aprovechamiento de los recursos cambian de manera más acelerada. Los tiempos se acortan y las transformaciones en el paisaje se vuelven evidentes. Es más, se busca el cambio, se lo provoca. La sociedad se proyecta políticamente hacia adelante con miras a transformarse y sepultar la barbarie del pasado colonial. El objetivo es enrumbarla hacia la civilización, encarnada a juicio de las elites políticas e intelectuales, por los países europeos. Gabriel García Moreno, Eloy Alfaro y Leonidas...

Realidades, mitos y retos sobre descentralización municipal, agua y saneamiento (Artículos)
Provedor de dados: 122
Autores: Vásconez, Mario.
La descentralización del Estado no es un proceso nuevo en la Subregión Andina, aunque en estos países tradicionalmente ha primado más bien la centralización económica, política y administrativa. "El estímulo a la descentralización en la subregión, coincide con una general aplicación de mecanismos de ajuste estructural, la globalización de las economías nacionales, un casi nulo crecimiento económico y el aumento de 1a pobreza y los conflictos sociales".

El tributo republicano indios y Estado en el Ecuador: 1830-1857
Provedor de dados: 122
Autores: Guarisco, Claudia.
El presente trabajo busca evaluar los factores que posibilitaron la adhesión indígena al mandato estatal de contribuir con el financiamiento de la asociación política a través del tributo. El escenario en que se desarrolla es la sierra nor-central y meridional de la actual república ecuatoriana y, temporalmente, abarca la primera mitad del siglo XIX. La investigación no pretende elucidar los factores subjetivos presentes en la legitimidad de la dominación, sino simplemente situar las condiciones en que los indios estuvieron más o menos dispuestos a acatar el mandato estatal. En ese sentido, el trabajo pone especial énfasis en las condiciones de vida del campesinado ecuatoriano, atendiendo al destino de los resguardos y a la incidencia que tuvo su...

La economía ecológica y las formas de propiedad del manglar de la zona norte de Esmeraldas
Provedor de dados: 122
Autores: Rosales Estupiñan, Mauricio.
Hay dos problemas urgentes por resolver en la zona norte de Esmeraldas: La pobreza de las comunidades locales, y la conversión (destrucción) de los manglares a camaroneras y sus externalidades. En la zona norte de Esmeraldas se encuentra el sistema de manglar comprendido entre los ríos Mataje y los alrededores de la desembocadura del río Santiago, con un extensión aproximada de 50.000 ha. Los manglares son un sistema ecológico abierto que interactúa con el mar, los estuarios, los esteros y la tierra firme; uno de los componentes de este ecosistema es el bosque de mangle, que se encuentra en los bordes alrededor de las diferentes islas, en las orillas de los ríos (esteros) y en la desembocadura de los ríos al mar, en franjas de 30 m a 100 m.

Nacionalismo en el Ecuador : ¿presente, pasado y futuro?

Autores: Nina, Andrea.
La imagen de Atahualpa, sus historias, sus valentías, sus grandezas ha sido una imagen que durante décadas ha formado parte de la mitología nacional. Tal vez se ha construido como uno de los pilares de la "identidad ecuatoriana". Esta mitología en torno a este "héroe" se ha repetido en los últimos cincuenta años repetidas veces sobre todo y con mucha fuerza, en los distintos enfrentamientos militares que ha tenido el Ecuador frente al Perú.  El último enfrentamiento bélico fue en enero de 1995 y condujo, al igual que los anteriores, a la efervescencia de un sentimiento de unión que provocó la imagen de una nación consolidada por lo menos durante los momentos más intensos del conflicto.  Sobre el nacionalismo ecuatoriano, hay quienes sostienen que el...

La presente investigación es el resultado de un estudio comparativo de dos casos de violación a los derechos humanos ocurridos en contextos sociales y políticos distintos. Se trata del caso "Restrepo" y el caso "Degollados", para Ecuador y Chile respectivamente. Planteamos que los casos "Restrepo" y "Degollados" se convirtieron en un problema de interés público al romperse los implícitos de la ciudadanía con respecto al tema de los derechos humanos, seguridad ciudadana y seguridad del Estado en los contextos socio-políticos particulares de Ecuador y Chile.

Autores: Torres de la Vega, Martha Gabriela.
The Guatemalan government I s counter insurgency campaigns of the 1980's resulted in the deliberate assassination of more than one hundred thousand people and the enforced exile of more than fifty thousand Guatemalans. In exile, Guatemalan refugees faced not only their memories of their violent past but also structured radical changes in their way of life. The restrictions placed upon them by living in United Nations sponsored camps transformed household economies and constrained refugees in multiethnic compounds.

Mientras tanto las experiencias del mundo real, cualesquiera sean su orientación o sesgo ideológico, en su abrumadora mayoría han sido muy poco eficaces en su propósito discursivo de reducir la pobreza y de incrementar la participación de las comunidades con mayores carencias en la gestión de lo público.

La estrategia es estudiar el desempeño del sistema de partidos en el periodo que va desde el retorno al régimen democrático en 1979 hasta la actualidad. En el primer capítulo (Elementos Teóricos) se sistematizan los referentes teóricos que sirven de base para el estudio empírico, aludiendo sobre todo a la teoría de sistemas, el enfoque institucionalista de la democracia y a las teorías elitistas...

En el territorio europeo, surgieron primero los caminos, y después recién sus ciudades. En el territorio latinoamericano, surgieron primero las ciudades y doscientos años después de su condición de estados independientes, aun no se han construido los caminos para entrelazarlas. La consecuencia es un continente compuesto de regiones cultural, social y económicamente heterogéneas, que establecen sus vínculos propios con el exterior, ausentes en la creación de aquellas trazas necesarias para promover el intercambio entre ellas. Mientras tanto, los manuales de historia continúan transmitiendo la visión euro céntrica de la génesis de las ciudades.

Estas prácticas y discursos interculturales se regularon en un contexto de negociación entre grupos indígenas, demás sectores guerrilleros y el Estado. La investigación trata las relaciones interculturales dentro de un marco regional, intentando así romper con la idea de grupos culturales aislados e ahistóricos que tradicionalmente ha sido el enfoque de la antropología colombiana.

El contexto del estudio involucra la categorización de las políticas de precios en tres períodos diferenciados, los que responden a contextos socioeconómicos distintos: en el modelo de sustitución de importaciones en los años 70, en medio de la fijación de las políticas de ajuste estructural, y en la nueva estrategia orientada hacia la promoción de exportaciones.

Sobre la tolerancia
Provedor de dados: 122
Ser??a la tolerancia una palabra con significados contradictorios. Aunque vista bien la cosa, la tolerancia parece tener dos  movimientos, un primero de rechazo, de  combate contra algo, y un segundo de aceptaci??n, admisi??n, aprobaci??, paciencia,  respeto, perd??n, consideraci??n o condescendencia ante ese algo.

Autores: Santana, Roberto.
El gobierno del presidente Sixto Dur??n Ball??n(1992-1996) ha dado inicio definitivamente al proceso de modernizqci??n del Estado. Una serie de leyes han venido siendo aprobadas, entre las cuales la ley de Modernizaci??n del Estado permite la descentralizaci??n, la desb??rocratizaci??n y la racionalizaci??n administrativas. adem??s de la privatizaci??n y la transferencia de los servicios p??blicos a la iniciativa privada. La toma de iniciativa, la discusi??n y aprobaci??n de diversos textos legales orientados a la modernizaci??n del pa??s se ha hecho y se sigue haciendo en medio de un contexto de desorden poUtico y de improvisaci??n jur??dica tales, que la duda se impone sobre su adaptabilidad a las exigencias del per??odo y en cuanto a su esperada...

Incidencia de la participación empresarial en el proceso de toma de decisiones en la integración andina durante los periodos 1988-1992 y 1992-1995. El caso del sector automotriz
Provedor de dados: 122
Autores: Garcés Almeida, Ivonne.
El Pacto Andino constituye un largo proceso de integración, que hasta la fecha no ha podido consolidarse debido a una serie de circunstancias, a pesar del permanente impulso dado por los diferentes gobiernos de turno; sin embargo, esta investigación se centra exclusivamente en la incidencia de los empresarios. Los esquemas de integración andina responden a un contexto internacional concreto al cual los países tienen que dar respuestas, puesto que impulsa a la adopción de esquemas específicos, más allá de las voluntades individuales de los actores que participan en el proceso de integración, entre ellos los empresarios. De hecho, el esquema original del Pacto Andino responde a un auge de la corriente cepalina que propugnaba un proceso de integración cerrado...

Los mecanismos de conversión de la deuda externa ecuatoriana a través del mercado secundario 1987-1993
Provedor de dados: 122
Autores: González J., Adela.
En los últimos años, en Ecuador, sí como en la mayoría de países de la región, la conducción y el debate económico ha girado alrededor de los programas de ajuste, la renegociación de la deuda externa y los mecanismos para su reducción, la modernización del estado y la apertura comercial. Estos procesos han constituido, en esencia, los mecanismos a través de los cuales las autoridades económicas han tratado de enfrentar el desafío planteado por la severa crisis económica y de deuda externa que se afronta desde 1982. La presente tesis constituye un esfuerzo para analizar y discutir algunos elementos relacionados con las implicaciones macroeconómicas de los canjes de deuda externa en general y en base del estudio de la experiencia ecuatoriana, extraer...

La política económica del Banco Central del Ecuador, ciclos recesivo y expansivo de política monetaria y control del tipo de cambio 1927-1937
Provedor de dados: 122
Autores: Oleas Montalvo, Julio.
Esta investigación analiza la política del Banco Central en su primera década de funcionamiento. La institución modelada por el profesor Kemmerer fue, en el proyecto modernizador concebido por la Revolución Juliana, el ejemplo de la entidad considerada como indispensable para impulsar el desarrollo nacional. Sus cuatro primeros años de funcionamiento estuvieron fielmente apegados a la ortodoxia determinada por su creador, pero a partir de 1932 la crisis deflacionaria producida por la estricta conjugación de los preceptos contenidos en la Ley de Monedas y en el primer estatuto del Banco Central, a cargo de los personeros de este último, hizo ineludible una radical variación de política. A partir de entonces, cambió la tendencia del nivel general de precios...

Guatemala women as refugees. a study of change in gender relations in the context of social movements
Provedor de dados: 121
Autores: Martha Gabriela Torres de la Vega; Torres de la Vega, Martha Gabriela.
The Guatemalan government I s counterinsurgency campaigns of the 1980s resulted in the deliberate assassination of more than one hundred thousand people and the enforced exile of more than fifty thousand Guatemalans. In exile, Guatemalan refugees faced not only their memories of their violent past but also structured radical changes in their way of life. The restrictions placed upon them by living in United Nations sponsored camps transformed household economies and constrained refugees in multiethnic compounds.
