Autores: Заика В.Е.; Валовая Н.А.; Повчун А.С.; Ревков Н.К.
В монографии изложены результаты многолетних сравнительных исследований по биологии и экологии черноморских митилид (Mytilus galloprovincialis, Mytilastei lineatus, Modiolus phaseolinus, M. adriaticus). Анализируются особенности распределения, размножения, темпов роста и другие популяционные характери­стики в зависимости от условий обитания моллюсков. Рассматриваются морфоло­гия и морфометрия митилид в онтогенетическом и экологическом аспектах, обсуждаются их роль в экосистемах моря и реакция на антропогенные воздей­ствия. Для. экологов, гидробиологов, специалистов по аквакультуре и охране ок­ружающей среды.

Autores: Гаевская, А. В.; Мачкевский, В. К.
The development of parasitic systems on artificial reefs is analyzed. Simple two-member parasitic systems wich are characteristic of parasites with the direct life cycle are first to appear; later multi-member systems composed by di- and tri-xenoparasites appear. Over the succession of the ecosystem on the reef quantitative and qualitative complicacy of parasitic systems increases.

Lepidapedon elongatum (Trematoda, Leporeadiidae) - ошибочно определенный паразит черноморской скумбрии.
Provedor de dados: 13
Autores: Гаевская А. В.
Факт паразитирования черноморской скумбрии (Scomber scombrus L.) трематоды Lepidapedon elongatum (Lebour, 1908) был отмечен в литературе дважды (Чернышенко, 1949, 1955). В первой из этих работ приводится подробное описание вида, снабженное оригинальной иллюстрацией. Это описание позднее вошло в "Определитель паразитов позвоночных..." (1975), но сопровождается иллюстрацией, заимствованной из статьи, где этот паразит описывается от глубоководного полорыла из вод Флориды (Manter, 1934).

Provedor de dados: 14
Autores: CARDOSO, M. J.; FREIRE FILHO, F. R.; ATHAYDE SOBRINHO, C.
Entre os fatores que limitam a produção do feijão macassar no Piaui, destaca-se a utilização de cultivares de baixo potencial genetico, associado a suscetibilidade a pragas e doenças, principalmente as viroticas que chegam a comprometer seu rendimento em mais de 70%. Objetivando melhorar o padrão de germoplasma no momento utilizado pelos produtores, a EMBRAPA/UEPAE de Teresina estar lancando a cultivar BR 14 Mulato por ter sobressaido nas avaliações de produção no Programa Integrado de Melhoramento de Feijão Macassar, coordenado pelo CNPAF. Esta cultivar e originaria da populaçãoa CNCx 249-313F, obtida do cruzamento entre os genotipos CNC 0434 x CNCx 27-2E.

Avaliação da eficiência da adubação organo-mineral na batata.
Provedor de dados: 14
Autores: OLIVEIRA, M. R. C. de.
No estado do Acre, a ausência de produção local de batata é explicada por diversos fatores destacando-se entre eles a susceptibilidade da cultura à murcha bacteriana, enfermidade comum em regiões de temperaturas elevadas e chuvas frequentes, aliadas a adubações inadequadas. a recomendação pela UEPAE Rio Branco de cultivares adaptadas às condições climáticas do Estado, foi a primeira tentativa no sentido de de estimular o plantio desta hortaliça entre os produtores acreanos. A indisponibilidade de material de plantio certificado (batata-semente) e o preços proibitivos dos adubos no mercado local, são fatores limitantes à adoção desta tecnologia. Desta forma, com o objetivo de determinar uma fórmula de adubação equilibrada para a cultura da batata, vem0se...

Autores: CAJUEIRO, I. V. de M.
A moderna tecnologia agrícola tem um custo muito elevado e, para que se justifique sua adoção plena, o agricultor necessita ter a garantia de lucratividade. No momento da colheita, a oferta do produto colhido é farta, devido ao fato de que todos os que o colhem o fazem na mesma época. A melhor maneira de garantir uma remuneração compatível com os custos de produção é adquirir um poder de retenção da safra, para comercializá-la no momento mais oportuno.

Autores: LIMA FILHO, A. B. de; MELO, L. A. S.
No Estado do Amazonas, a bovinocultura de corte mista e' explorada com baixo nivel tecnologico. Os rebanhos demonstram desempenho produtivo e reprodutivo inferior aos de outras regioes, em decorrencia principalmente de altas temperaturas, umidade e pluviosidades, que incidem na regiao; padrao zootecnico dos animais; ocorrencia de doencas; manejo inadequado; alimentacao deficiente; superlotacao; e degradacao das pastagens. Diante desse contexto, e' relevante, para as instituicoes que desenvolvem pesquisa com pecuaria, a priorizacao das seguintes linhas de pesquisa com bovino: melhoramento genetico, sanidade animal, manejo animal, alimentacao e nutricao e pastagem.

A azolla e a cultura arrozeira.
Provedor de dados: 14
Autores: RUSCHEL, A. P.
A azolla é uma planta aquática; possui uma alga capaz de absorver o nitrogênio do ar atmosférico, vivendo no interior de suas folhas. Atualmente, tem sido mais utilizada como fonte de nitrogênio e outros macro e micronutrientes na cultura arrozeira irrigada e como aceleradora da decomposição da palhada do arroz, facilitando o melhoramento do solo para o plantio subsequente. Há registro do aumento de produção por influência da introdução da Azolla no cultivo de arroz em diversos locais.

Como alternativa para o incremento da pecuaria de corte no Pantanal, o bufalo Bubalus bubalis, apresenta-se como um potencial favoravel devido a sua rusticidade e adaptabilidade aos ambientes da planicie pantaneira. Visando avaliar o aproveitamento das forrageiras nativas da sub-regiao da Nhecolandia pelos bubalinos, utilizou-se a tecnica microhistologica de analise fecal (Hansen et al., 1971). Foram identificadas 53 especies nativas que mais contribuem na dieta dessa especie na sub-regiao. Os locais com maior incidencia de pastejo foram: campos altos e cordilheiras (ambos com 34%), campo inundavel (17%) e baia (15%). Axonopus purpusii e Elyonurus muticus sao predominantes nas pastagens e contribuem muito na dieta. E. muticus e caracterizado por ser...

Avaliação agronômica de capim-elefante (Pennisetum purpureum cvs. Cameroon e Anã) sob três frequências de corte.
Provedor de dados: 14
Autores: COSTA, N. de L.
O ensaio foi conduzido no campo experimental da UEPAE Porto Velho, da EMBRAPA, durante o periodo de marco/1987 a novembro/1988. O delineamento experimental utilizado foi em blocos casualizados com tres repeticoes. Os tratamentos consistiram de duas cultivares de capim-elefante (Cameroon e Ana) e tres frequencias de corte (28, 42 e 56 dias). As parcelas mediam 4,0 x 4,0 m tendo uma area util de 4,0 m2. Resultados permitiram concluir que o aumento do intervalo entre corte, em ambas as cvs. de capim-elefante implicou em maiores rendimentos de MS e PB, contudo, provocou decrescimos significativos nos teores de PB. As duas cultivares de capim-elefante apresentaram desempenho agronomico semelhante, exceto para cortes a cada 28 dias, onde a cv. Ana foi superior a...

Efeitos da adubação orgânica e do fósforo sobre a produção de alho em Rio Branco-AC.
Provedor de dados: 14
Autores: OLIVEIRA, M. R. C. de; PEREIRA, J. B. M.
O alho é a quarta hortaliça em importância econômica para o Brasil (Filgueira 1982), e o seu cultivo continua em expansão, porém, apresentando de modo geral rendimentos baixos. Segundo Galli et al (1968), citado por Mascarenhas et al (1985), as principais causas desses baixos rendimentos são as doenças causadas por fungos. No Estado do Acre, além das condições climáticas favoráveis às doenças fúngicas, a baixa produtividade deve-se à falta de práticas culturais e fórmulas de adubação adequadas para a cultura. Todos esses fatores são imperativos na pesquisa do alho para essa região. O alho é bastante exigente em nutrientes, principalmente o fósforo e o nitrogênio, e os solos do Acre na sua maioria necessitam de correção de fertilidade, sendo este outro...

A agricultura estadual é caracteristicamente do tipo familiar e baseada em cultivos consorciados. Tal fato cria para os órgãos de pesquisa e extensão o compromisso de gerar sistemas de produção capazes de incorporar as demandas tecnológicas daí decorrentes. O que se observa no entanto, é que os resultados obtidos estão aquém das necessidades, estimulando assim, estudos que possam preencher as lacunas existentes.

Avaliação de cultivares de milho precoce no município de Brasiléia-Acre.
Provedor de dados: 14
Autores: PIMENTEL, F. A.; LODI, N. V.
O cultivo de milho (Zea mays L.) é de grande importância para o município de Brasiléia. Este município se situa à margem esquerda do rio Acre, fazendo fronteira com a cidade boliviana de Cobija, através do igarapé Bahia e distando 222 km de Rio Branco. Esta cultura é utilizada na alimentação humana, na ração animal e o excedente da safra é comercializado nos mercados de Brasiléia, Rio Branco e Cobija. Embora a cultura do milho seja tradicional no município, sua produção não atende à demanda, pois ocorrem excedentes apenas na safra (março/maio). Este estudo em como objetivo obter cultivares de ciclo curto visando efetuar dois cultivos por ano, iniciando o primeiro cultivo em setembro/outubro e colhendo em março/abril, uma vez que o agricultor tem o hábito...

Plantio direto do feijão na palha do arroz: alternativa para controle da "Mela do Feijoeiro".
Provedor de dados: 14
Autores: CAMPOS, I. S.; GOMES, T. C. de A.; PAZ, F. das C. A.
A doença conhecida como Meia do Feijoeiro", causada pelo fungo de solo (Thanatephorus cucumens), é um dos fatores limitantes da cultura do feijão (Phaseolus vulgaris) na região amazônica. A produtividade obtida no Estado do Acre, nos últimos anos, não ultrapassou 600 Kg/ha. Nesta região, as lavouras tradicionalmente implantadas na segunda quinzena de março e início de abril, geralmente, são atacadas pela "Mela» com perda total da produção. Mesmo quando as plantas chegam a frutificar, os grãos são danificados pela doença. Agricultores que plantam um pouco mais tarde, conseguem colheitas razoáveis. Entretanto, o plantio tardio tem provocado muitas perdas devido a falta de chuvas por ocasião da floração do feijão. Com o impacto da chuva o fungo presente no...

A citricultura no mundo e no Brasil.
Provedor de dados: 14
Autores: PASSOS, O. S.
A citricultura é uma das atividades agrícolas de maior relevância no mundo, destacando-se entre as espécies frutíferas, como a mais importante, tendo superado as culturas da banana, uva e maçã (FAO, 1988). A razão básica desta expressão estaria na adaptação ecológica das plantas cítricas em todos os continentes dentro da faixa intertropical compreendida entre o Japão, a 40º de latitude Norte e a Austrália, em latitude aproximadamente igual, só que no Hemisfério Sul. Outras ponderações estariam ligadas ao consumo generalizado das frutas cítricas, independente do segmento da sociedade, e a baixa densidade das plantas por hectare, induzindo a utilização de maior espaços físicos.

Comportamento de cultivares de alface (Lactuca sativa L.) de verao em varzea do rio Solimoes.
Provedor de dados: 14
Autores: CARDOSO, M. O.
Visando avaliar o comportamento de cultivares de alface de verao em condicoes de varzea do Amazonas, um experimento foi conduzido no Campo Experimental do Caldeirao, no municipio de Iranduba, em delineamento de blocos ao acaso, com 4 repeticoes, sendo os tratamentos constituidos pelas cultivares Vitoria, Regina, Simpson e Brisa. A colheita foi ralizada em tres datas diferentes. Segundo os dados de producao, o peso medio de todas as cultivares foi abaixo (inferior a 200g/planta), provavelmente com consequencia da alta temperatura (media= 26,6oC) ocorrida no periodo de conducao do experimento.

Como sao restritos os trabalhos de pesquisas para se conhecer o real comportamento de cabras Marota, a EMBRAPA/UEPAE de Teresina desenvolveuo presente estudo com o objetivo de avaliar a sua variacao anual de peso. O trabalho foi conduzido entre janeiro/82 e dezembro/88, em Castelo do Piaui, onde os animais eram mantidos em pastagem nativa, em sistema de pastejo direto, a uma taxa de lotacao de 1,5 ha/animal/ano. Nos periodos secos, quando havia escassez de forragem, os animais eram suplementados com capim verde e restolhos de culturas. Verificou-se pelasmedias dos dados que nao houve variacao anual de ganho de peso vivo dos animais, apenas uma tendencia de no periodo seco, devido a suplementacao alimentar.

Avaliação de germoplasmas de Centrosema sp. nas condições edafoclimáticas de Rio Branco, Acre.
Provedor de dados: 14
Autores: VALENTIM, J. F.
O ecossistema das pastagens cultivadas estabelecidas no Acre, onde se verificam ciclos de utilização predominante de uma espécie forrageira, se contrapõe à diversidade natural na floresta tropical úmida da região. uma vez rompido o equilíbrio ecológico, o plantio homogêneo das pastagens favorece o aumento acentuado nas populações de certos organismos (insetos, fungos, bactérias e nematódeos) que passam a se constituírem em pragas e doenças das pastagens. A diversificação das pastagens, através da utilização de leguminosas na forma de pastagens puras (banco de proteínas) e em consorciação com gramíneas, se apresenta como alternativa tecnológica economicamente viável para a formação, melhoramento e renovação de pastagens degradadas no Acre.

São apresentadas informações sobre a cultura da banana e "plátano" no que concerne as principais regiões produtoras do mundo, sistemas de cultivo adotados em áreas tropicais, subtropicais e trópicos úmidos e importância social e econômica dessas culturas nestas regiões. Há uma imensa área cultivada com esses produtos, superior a 4,0 milhões de hectares, a qual gerou produção estimada em 65,8 milhões de toneladas métricas em 1988, das quais apenas 7,0 milhões foram exportadas. Cerca de 58,8 milhões de toneladas métricas destinaram-se ao consumo humano nas próprias regiões produtoras, especialmente pelas populações de baixa renda. Ha regiões em que o consumo per capita aproxima-se de 1kg/dia; em outras gera beneficios econômicos através de sua contribuição...

Influência da cobertura e do pH do solo na incidência da "mela" do feijoeiro (Phaseolus vulgaris L.).
Provedor de dados: 14
Autores: RITZINGER, C. H. S. P.
a "mela" é uma doença que limita a produção de feijão na Região Amazônica em função de não existir um método de controle tecnicamente viável para o agricultor, nas condições atuais de infraestrutura da região. Tem como agente causal Thanatephorus cucumeris, um fungo de solo, com habilidade de sobrevivência no solo por muito tempo através de estruturas de resistências, escleródios. Ensaios realizados na UEPAE Rio Branco indicaram que a incorporação de resíduos culturais ao solo pode favorecer o desenvolvimento de fungos antagônicos ao agente da "mela" favorecendo, portanto, a redução do inócuo potencial do solo. Com base nestes trabalhos, foram instalados ensaios visando verificar o efeito da cobertura morta sob dois níveis de pH do solo na incidência da...

Research and the northeast brazilian citrus industry.
Provedor de dados: 14
Autores: PASSOS, O. S.
A review is made focussing on the influence of EMBRAPA's (Brazilian Enterprize for Agricultural Research) program on the development of the citrus industry in Northeastern Brazil, one of the poorest regions of the country. This region comprises almost 20% of the total land surface and almost 30% of the country's population and exhibits serious social and economic contrasts. Due to this extensive area (approximately 1,600,000 km(quadrado) and the large range of climates and soils, although the annual rainfall in almost 60% of the total area is less than 750 mm, the export/import balance is always favorable. Neverthless, continually unbalanced growth between north and south has brought several social problems to the country as a whole. Recognizing this...

Sistemas de cultivo com leguminosas e seus efeitos sobre a produtividade das culturas e propriedades de um solo no Acre.
Provedor de dados: 14
Autores: GOMES, T. C. de A.; CAMPOS, I. S.
No estado do Acre, o manejo de sistemas agrícolas utilizado, baseia-se na broca, derruba e queima da floresta, utilização da área durante poucos ciclos produtivos (2 a 3 anos), seu consequente abandono e abertura de novas áreas, de forma a dar continuidade ao manejo itinerante ou migratório. Além do aumento de problemas com invasoras, pragas, doenças e erosão, o esgotamento da fertilidade do solo tem sido um dos principais motivos para o abandono das áreas exploradas. Com o objetivo de avaliar o efeito do uso de leguminosas em diferentes sistemas de manejo sobre o rendimento de culturas anuais e propriedades químicas, físicas e biológicas do solo, foram instalados em 1987, dois experimentos no campo experimental da UEPAE de Rio Branco.

Tendo por objetivo avaliar o potencial de respostas das pastagens nativas de campo cerrado do Amapá os uso de fertilizantes químicos, foi desenvolvido um ensaio de fertilização nas fazendas São Jorge e Campineiro, localizadas nos municípios de Amapá e Macapá, respectivamente. O solo da primeira fazenda e do tipo Latossolo Amarelo de textura media, enquanto na segunda e concrecionario lateritico, ambos acidos e de baixa fertilidade natural. A cada dois meses no período das chuvas e a cada três meses no de estiagem, cortes de 15cm do solo eram realizados para determinação da produção da meteria seca. Embora diferenças significativas tenham sido observadas, os acrescimos obtidos podem ser considerados baixos, principalmente, levando-se em conta os níveis dos...

Cultivares de milho recomendadas para o Estado do Acre.
Provedor de dados: 14
Autores: COSTA, J. G. da; CAMPOS, I. S.
Um dos aspectos que pode proporcionar aumentos substanciais na produtividade de uma cultura é a utilização de cultivares com alto potencial genético e adaptados às condições locais. No Estado do Acre, devido a falta de estrutura para multiplicação de sementes, a importação deste insumo é realizada anualmente, pelo comércio e Secretaria de Desenvolvimento Agrário.

No período de 1980 a 1984, foi conduzida, em Londrina, PR, uma serie de cinco experimentos, objetivando quantificar o efeito de diferentes populações de percevejos sobre o rendimento e seus componentes, as características agronômicas e a qualidade da semente de soja. A cultivar utilizada foi a UFV-1, por sua característica de ciclo longo, constando o experimento de seis tratamentos que previam a aplicação de endosulfan (525 g i.a./ha) quando a população de ninfas grandes e adultos de percevejos (Nezara viridula, Piezodorus guildinii e Euschistus heros) atingisse 1, 2, 4 ou 6 exemplares por metro de linha. Adicionalmente, havia um tratamento com aplicação de inseticida em caráter preventivo, de forma a impedir o surgimento de percevejos nestas parcelas, e...

Os solos do Acre, dominados por florestas tropicais úmidas, quando utilizados para agricultura, são submetidos ao manejo migratório praticado por agricultores de recursos muito limitados. Embora o citado manejo se adapte a agricultura de subsistência em regiões fracamente habitadas, torna-se insustentável a medida que a densidade populacional aumenta. O regime pluviométrico e a exposição direta do solo As intempéries durante os períodos de cultivo, têm como resultado o depauperamento do mesmo após dois ou três anos. Áreas de vegetação secundária onde não foi permitido o tempo de pousio necessário para a recuperação natural da fertilidade, são reincorporadas ao processo produtivo acentuando os danos causados pela erosão.

Autores: ALVES, J. E.
Cultivam-se no Nordeste diversas fruteiras tropicais de significativa importância tanto para o mercado regional e nacional como internacional. Os cultivos são em sua maioria tradicionais, com baixos índices de capitalização e níveis tecnológicos. Contudo, há um alto potencial para cultivos intensivos, especialmente se levar em consideração a meta do governo de irrigar um milhão de hectares na região até 1990. Este fato, associado a disponibilidade de várias tecnologias geradas pelo Sistema Cooperativo de Pesquisa Agropecuária-SCPA, coordenado pela EMBRAPA, tornará possível elevar a produtividade e melhorar a qualidade de produtos com abacaxi, banana, citros e manga, dentre outros, em diversas regiões produtoras.

Deep diving service submarines
Provedor de dados: 5
Autores: Freitas, A.
Service submarines have been developed for support duties in offshore operations in deep waters. Three submarine concepts have been designed for water depths ranging from 400 to 1500 m. The operation philosophy is to use an autonomous manned submarine as a carrier for components, tools and work modules and as a base for IMR operations on subsea installations. The design principles are similar to that of the Space Shuttle incorporating a payload bay, energy supply and a closed environment for the crew and operators. The operation profile of an offshore submarine demands capabilities above those of naval submarines: deep diving, long endurance underwater, dynamic positioning. New technology had to be developed: air-independent energy system, regenerative...

Photosynthèse et nutrition carbonée chez ULVA SP
Provedor de dados: 5
Autores: Piriou, Jean-yves; Duval, Valérie.
Laboratory experiments have been conducted in order to examine the grouth of ULVA SP. Results show that growth suddenly stops at a precise moment. Collectively, the results of simultaneously analysis of culture media constituents demonstrate that several components may alter the growth process of UIva sp. Based on the culture experiments, we argue that the gowth responses of UIva sp. are unaffected by pH or oxygen concentrations, but field plants of ULVA sp. are libely to be ponctually limited in growth by carbon (DIC) depletion, together with nitrogen limitation and pigments degradation.

IFREMER aims at digitalizing trawl gear in order to reach two goals: on the one hand, participating in the realisation of a computer assisted trawl conception software; on the other hand, being able to study quickly and easily the influence of different adjustment parameters on the shape of the trawl in order to indicate to the skipper, if possible in real time, the optimal adjustment for the conditions he's in. From an international point of view, there are only two strategies to approach this problem: - the first strategy is based on statistical studies on the existing nets (almost limited to their reproduction on different scales), but this approach does not leave much room for innovation as it can only be applied to the same type of nets as those that...

The market for fresh sole and its importance in northern french fisheries
Provedor de dados: 5
Autores: Ioannidis, Chris; Lantz, Frederic.
(Not controled OCR) Sole is a species whose market has been expanding steadily since the end of the 70's ; landings have doubled, from 4097t in 1979 to 8048t in 1987. In real terms (1980=100) the value of landings has increased from FF124 m to FF265 m over the same period. One must appreciate that the importance of fresh sole lies in its high valuation. Despite the fact that the species occupies no more than 1.66% of total landings in terms of weight, in value terms exceeds 8.5% of the total, making sole the third most valuable species in France. Sole is consumed essentialy fresh and its price to the consumer does not therefore depend on any transformation process. It depends solely on demand and supply (domestic landings plus imports) conditions. The role...

Ecosystemes benthiques profonds et chimiosynthese bacterienne: Sources hydrothermales et suintements
Provedor de dados: 5
Autores: Laubier, Lucien.
Hydrothermal communities of various species compositions have been described from the eastern and western Pacific and Atlantic. Brine and cold seeps and hydrocarbon seepages have been found off Florida, off the Oregon and Japanese subduction systems, on the Laurentian Fan, near Barbados, and off Louisiana. Biomasses range from 10 to 70 kg/m super(2), fresh weight. Basic microdistribution of species groups in aureoles centered around hydrothermal vents reveals different levels of adaptation to harsh physico-chemical conditions. Two groups of primary producers can be recognized: a highly efficient cool water group with large vestimentiferan tube worms and bivalves, and alvinellid polychaetes adapted to hot waters. Both groups are exploited by specific...

Une procédure systématique pour le sous-échantillonnage des prélèvements de plancton
Provedor de dados: 5
Autores: Koutsikopoulos, Constantin; Petitgas, Pierre.
It is often necessary to sub-sample plankton samples even if the precision of the estimation is thereby decreased. A methodological optimization is looked for. The variance depends on the procedure of construction of the aliquot (strategy) and the number of individuals counted (effort). The sub-sampling effort is allocated in a general context of repartition of the total effort between sampling and sub-sampling. This effort depends on the time consumed by the sub-sampling procedure, the volume of the aliquot and the number of individuals counted. For the same effort, a systematic procedure for the construction of sub-samples is more precise than a random one because it travels through the entire sample and is thus less dependent on the spatial distribution...

Autores: Michard, A; Montigny, R; Schlich, R.
Rare earth element abundances and Sr, Nd, Pb isotope compositions have been measured on zero-age dredge sample from the Rodriguez Triple Junction (RTJ) and the South-East Indian Ridge (SEIR). Along the SEIR, the geochemical "halo" of the St. Paul hot spot has a half-width of plus or minus 400 km and the data may be fairly well accounted for by a binary mixing between an Indian MORB-type component ( super(87)Sr/ super(86)Sr = 0.7028, super(143)Nd/ super(144)Nd = 0.51304, super(206)Pb/ super(204)Pb = 17.8) and the plume-type St. Paul component (0.7036, 0.5129, and 18.7 respectively). The RTJ has distinctive geochemical properties which contrast with those of the adjacent ridge segments. Low super(206)Pb/ super(204)Pb ratios which plot to the left of the...

Effets de l'apport de phytoplancton (Skeletonema costatum) sur la croissance et les variations de la composition biochimique de la palourde japonaise Ruditapes philippinarum cultivée en marais
Provedor de dados: 5
Autores: Baud, Jean-pierre; Haure, Joel; Garnier, Jacqueline.
A bulk production of phytoplankton (Skelelonema costatum) has been obtained in concrete tanks from saline groundwater. This was used in various concentrations to feed an intensive cultivation of the Manila clam (Ruditapes philippinarum) in ponds. No difference was observed in growth rates of molluscs, with food concentrations between 31 to 126 µg/l Chl a. However, the growth rates obtained from March to November with a food supplement were 1.5 times higher than those observed in the traditional, extensive cultivation. The biomass doubled and the increase in flesh dry weight was 2.5 times higher. The condition index reached a value of 100 in the intensive cultivation. During growth, the proximate composition analysis revealed that the lipid and carbohydrate...

Modelisation de la coherence spatiale du bruit genere par les vagues

Autores: Plaisant, M.
Empirical models already exist for ambient noise spectral density function of frequency, sea state or wind speed but they give no information on the spatial structure or coherence of the noise field which is essential as soon as array beamforming is involved. We have developed a model which computes the spatial coherence matrix of the noise field due to a continuous distribution of sources located at the sea surface, and also the noise power spectral density after classical beamforming on an equidistant hydrophones linear array. In this model, propagation effects like rays bending due to variations of index of refraction and multiple bottom and surface reflections are taken into account. Principles of the modeling are presented and results demonstrate that...

During the world tour of R/V Jean Charcot , 2 types of polymetalic deposits have been investigated: the cobalt-rich crusts in the Tuamotu Archipelago (French Polynesia) and the manganese nodules in the Clarion-Clipperton Fracture Zone. In the South Pacific Ocean, a genetic model of site bearing cobalt-rich crusts has been identified: the polymetallic deposits are located at a 1,000 m water depth on a subsident fossil atoll built on a volcanic substrate. In the North Pacific Ocean, a 2 months cruise has been conducted on the basis of preexisting data (seabeam, bottom photographs, nodules and sediment sampling). Three types of geological environment have been characterized: a sedimentary plateau, an area particularly representative of the abyssals hills...

Une approche analytique permet de coupler un modèle physique avec un modèle biologique qui prédit la croissance des huîtres en fonction de la quantité, de la qualité de la nourriture particulaire et de la température. Ce modèle montre clairement l'effet de surcharge du bassin induisant un ralentissement des performances de croissance avec un gradient marqué du nord au sud. Un modèle phytoplanctonique basé sur les apports respectifs en nitrates de la Charente et de l'océan permet de prédire la production primaire en fonction de la température et de la transparence de l'eau. Une simulation supprimant les apports de la Charente permet de préciser la quantité de phytoplancton dépendant de ces apports. Un troisième modè le s'applique à représenter dans une...

Etude expérimentale de la rétention et du tri particulaire chez Crassostrea gigas : utilisation de régimes alimentaires monospécifiques composés d'Haslea ostrearia
Provedor de dados: 5
Autores: Barille, Laurent.
L'aquaculture extensive de l'huitre japonaise Crassostrea gigas représente, avec 130 000 tonnes par an, la première ressource marine nationale (Heral, 1986). Le bassin de Marennes-Oléron, qui compte pour 40 %  dans cette production, enregistre depuis vingt ans un ralentissement de la croissance des huîtres. La capacité trophique du bassin, production du phytoplancton et apport organique, ne permettrait pas une production optimale compte tenu du stock de mollusques actuel (Heral et al., 1990). Une partie de la réponse passe par une meilleure compréhension de l'adaptation trophique de Crassotrea gigas soumise dans ce milieu estuarien, à des variations marquées de la qualité et de la quantité de la nourri ture disponible. Dans le but de mieux comprendre les...

Cruise Seamewe 2 has been devoted to the survey of the projected track of a telecommunication cable on a distance of 2300 miles between Djibouti and Colombo. Supplementary data relevant to Djibouti approaches (side scan survey) and the areas were obtained during Leg 1 of Seamewe. The survey involves the seabeam for bathymetry and a mud penetrator 3.5 KHz with a correlator for determination of the acoustic character of the sea floor. Magnetism and gravimetry have been also recorded on most of the surveyed tracks. The near-bottom water temperature had also to be checked in a number of stations.

Autores: Camus, Patrick; Treguier, Cathy; Le Gars, Jean-claude.
La Petite Mer de Gâvres est une zone conchylicole classée salubre. L'activité principale actuelle est la pêche à pied semi-professionnelle ou familiale des coquillages et gastéropodes. De ce fait la denrée échappe 0 tout contrôle sanitaire.  A la suite de problèmes de salubrité rencontrés sur les coquillages de cette zone (rapport DRV 89-002 CSRU/La Trinité/Mer) une étude bactériologique plus approfondie portant principalement sur les coquillages fouisseurs (palourdes) a été entreprise pendant l'année 1989 sur 8 points d'observations.

Spatial scales of mesoscale variability in the North-Atlantic as deduced from geosat data
Provedor de dados: 5
Autores: Le Traon, Pierre-yves; Rouquet, Mc; Boissier, C.
Two years of Geosat data were used to systematically investigate the mesoscale variability and spatial scales of the North Atlantic. We first calculated sea surface height variability and eddy kinetic energy. These compare well with the eddy kinetic energy obtained with surface drifters. Then the spatial scales of mesoscale variability were characterized in 10° (latitude) × 10° (longitude) areas by their wave number spectra and autocorrelation functions. Comparison with existing in situ data shows good agreement, and it is believed that the total error budget is globally below that of the oceanic signal. The wave number spectra show significant differences as a function of latitude and longitude, and these can be related to different types of forcing...

Les enjeux de la recherche en économie maritime
Provedor de dados: 5
Autores: Abric, M; Weber, Jacques.
In September 1989, Mr Pierre Papon, Chairman of the IFREMER, expressed his wish for a study on the issues of research in marine economy. Carried out under the direction of Jacques Weber, this document is the result of this study. Dealing with marine economy equals, mutatis mutandis, dealing with terrestrial economy: the uniqueness of the subject, economy, as that of the marine element, hides a wide heterogeneity and a multiplicity of research questions. This is the reason why eight different fields were chosen to be investigated. It was decided to take an inventory, for each field, of all the specialised research centres, and to interview their directors or some specialists. Interviews were thus carried out by sector.

Following the development of the hatchery tool, different triploidy induction techniques have been tried out in vitro. The method using cytochalasin B was selected and successfully applied to cupped oysters, Crassostrea gigas and especially to clams, Ruditapes philippinarum. Larval survival rates were lower than control rates. On the other hand, larvae's growth speed was comparable. These methods will now be used to produce significant test populations which will then be cultivated in French coastal waters.

Sediment instability appears to be important as a part of global sedimentary budget. Among the various types of sedimentary instabilities, submarine slides are probably the most spectacular and the hardest to study and predict, although their consequences on human and industrial marine activities can be dramatic. IFREMER is conducting a research project on this topic. An area off Nice (France) has been particularly studied because of its recent activity. Mapping and instability area detection have been carried out. With the possibility of direct interactive observation and highly accurate submarine in -situ operation, the submersible is an extremely efficient tool for sediment studies, but diving purposes have to be precisely defined to provide useful...

Une recherche des causes de la mortalité des moule au printemps dans le Pertuis Breton a été entreprise en 1989. La faible pluviométrie observée cette année là n'a pas entrainé de dessalures importantes et les mortalités constatées ont été si faibles qu'elles n 'ont pas eu de conséquences sur la production de moules. Les essais réalisés en milieu contrôlé ont montré que même pendant la période de reproduction au cours de laquelle les moules sont plus fragiles, il fallait des salinités inférieures à 15 p . mille et se maintenant pendant plusieurs jours avant que des mortalités n 'apparaissent. Il est prévu de remettre le même programme en place au printemps 1990.

Disappearing of oxygen, mainly tabes place in the breeding areas and near the bottom because of the concentration of shells and the abundance of biodeposit. A correlation is shown between the level of the oxygen in the water and the speed of the wind which is the main factor of balance.

Management of oyster and mussel culture
Provedor de dados: 5
Autores: Heral, Maurice; Drinkwaard, A.; Bohle, B.; Figueras, Antonio; Lavoie, R.; Maurer, Daniele.
The world aquaculture production (fresh and marine waters) achieved 11.1 million tonnes in 1986 (FAO, 1989). The molluscs represented 21 % of the total production. Marine aquaculture with 5.45 million tonnes reached 49% of the total production. The marine cultivated mollusc production was 2.25 million tonnes due mainly to oysters (36%), mussels (34%), clams (16%), and scallops (6%).  As the aquaculture production is clearly identified in the statistics only since 1984, the evolution of the production of oysters and mussels for the last 15 years has been analyzed with the FAO data for the total catch (fisheries and culture). By comparison of the two statistics for the same year (1986), the fisheries represented only 17% for oysters and 16% for mussels. Fig....

Two studies of depuration, one in laboratory conditions and the other one in an oyster's pond were performed using 2 sets of contaminated mussels with diarrhetic toxins at a high and a low level (3 and 1 M.U.). Depuration kinetics were followed both by the adult mouse test and okadaïc acid analysis. Results are - in the pond, high toxic mussels need about 20 days to become eatable (toxicity level : 0.5 M.U.g-1 digestive glands), -this time decreases when the initial toxicity is low but it increases when mussels are underfed, - a good correlation is observed between the total toxicity and okadaïc acid concentration.

The focus of the Rapanui expedition, part of the "Tour du monde" of the French research vessel Jean Charcot , was to collect detailed structural and geophysical data along the northern and southern Easter microplate boundaries in order to test, in a rigorous manner, the most recent tectonic and kinematic models for the microplate. In developing detailed bathymetric, morphotectonic and magnetic maps of these boundaries, we have found that our new plate boundaries differ considerably from those of Hey et al. (1985).

Impact sanitaire de la navigation de plaisance
Provedor de dados: 5
Autores: Leon, Michel.
Lors des récentes décennies, le parc des bateaux de plaisance s'est fortement accru en France. Cela a nécessité la construction de ports exclusivement réservés à cette activité. La création d'ouvrages portuaires offrant un accès et un abri permanents a attiré une nouvelle clientèle de plaisanciers. On a assisté simultanément à un développement anarchique des mouillages individuels, posant un problème de coexistence avec les activités de pêche et de conchyliculture. Depuis 1980, le parc des bateaux de plaisance a progressé de 5 % par an en moyenne, sans amélioration sensible des équipements sanitaires à bord. La saturation des ports existants, liée à la faible mobilité de nombreux bateaux, nécessiterait la création d'infrastructures supplémentaires. Mais...

Consommation des produits de la mer

Autores: Piquion, Jean-claude.
« En France, on ne mange pas de poisson » voici une de ces affirmations couramment répandue, dont on sait quelle réalité elle dépeint. Cette petite phrase témoigne sans doute, un moment ou un autre, d'une période de récession, de baisse des cours ou d'une certaine mévente des produits de la mer. Néanmoins, si l'on s'en réfère à certaines études, d'aucuns seront peut-être étonnés de savoir que la France se situe tout de même au 7ème rang européen des pays consommateurs des produits de la mer. Aussi convient-il de s'interroger sur l'adaptation de la production française (frais, transformés et produits destinés à être transformés à l'évolution de la demande ?

From 1988 to 1989, a study has been conducted pertaining to the growth of the flat oyster Ostrea edulis, as well as Marteilia refringens and Bonamia ostreae outbreaks.  Commercial mono specific farming (flat oysters), with low density or mixed (flat and hollow oysters) along with higher density, has been taking place in the Arcachon basin oceanographic sectors, where main hydrobiological parameters were acquired simultaneously.   The excellent growth of the flat oyster was witnessed in mono specific farming. However this growth was average in mixed farming, probably due to higher total oyster density and interspecies competition. Regardless of the type of farming, Marteilia refringens infection was very quick and may have been related to climatic bay water...

Sublethal and histopathological effects of trace levels of tributyltin fluoride on adult oysters Crassostrea gigas
Provedor de dados: 5
Autores: Chagot, Dominique; Alzieu, Claude; Sanjuan, Jane; Grizel, Henri.
Shell malformations and histological effects of environmental concentrations of TBTF (2, 13.1 and 64.8 ng/!) were assessed on adult oysters Crassostrea gigas during a I-month experiment, incIuding both an exposure and a depuration phase. The results showed that the digestive gland is the primary target organ. Recoverable modifications were observed at the lowest concentration. Limited necrosis was observed at the highest concentration and a longer exposure could have led to extensive and irreversible tissue lesions. Shell malformations (chambering) were observed during the depuration phase. Finally the authors suggest that safe TBT levels in mariculture waters should be lower than 2 ng/l.

Jamstec/deep tow camera system (on the manned submersible "SHINKAI 2000 vehicle")
Provedor de dados: 5
Autores: Otsuka, K.
The JAMSTEC/Deep Tow Camera System conducts pre-site-surveys for the manned submersible "SHINKAI 2000". The vehicle is towed by double armored coaxial cable (RG-8/U) of 4500 m length. The color composite video signal is converted to an FM signal with central frequency of 6.15 MHz because it is very difficult to compensate completely for the transmission loss of video frequency through the coaxial cable. The data from the CTD sensors and the altimeter are displayed with date and time on the monitor screen in real time. Temperature data has proved very important in finding hydrothermal anomaly phenomena. Two years ago, our research group found an active chimney at North Fiji Basin during cooperative cruise between France and Japan. Last year, we deployed...

The North Fiji Basin (NFB) is a shallow oceanic basin, with depths between 2000 and 4000 m, which lies between latitude 10 degree and 25 degree South and longitude 170 degree and 180 degree East. Situated at the boundary of the Indo-Australian and Pacific plates, the NFB stands between two subduction zones of reverse polarity: the New-Hebrides subduction on its western side and the Tonga. The aim of the Seapso 3 cruise of N.O. Jean Charcot (December 1985), was to delineate the recent spreading location in the North Fiji Basin, and to observe possible associated hydrothermal manifestations. For that we first have performed a large scale bathymetric and geophysical survey and then a detailed survey (complete coverage Seabeam) on two boxes. Finally, rocks...

Génétique des populations de bivalves en milieu lagunaire: la palourde dans l'étang de Thau (Méditerranée)
Provedor de dados: 5
Autores: Borsa, Philippe.
The genetic structuration of populations of the palourde, Ruditapes decussatus, a bivalve species of the Mediterranean coastal lagoons, was studied at the enzymatic gene level, in relation to their ecology and their demography. A genetic comparison of local populations of the Languedocian lagoons suggested that they constitute a metapopulation. In the Thau lagoon, genetic heterogeneity could be related to demographic features. Genetic differences between cohorts appeared to account for significant heterozygote deficiencies, although not fully explaining them. For this, a Wahlund effect could be rejected. The hypothesis of selection affecting pre-recruits appeared most likely and it was confirmed by preliminary results of experiments conducted on larvae. It...

Impact of oceanic asperities on the tectogenesis of modern convergent margins
Provedor de dados: 5
Autores: Lallemand, S; Collot, J-y; Pelletier, B; Rangin, C; Cadet, J-p.
This paper presents some of the implications of oceanic asperities in subduction zones, based on examples gathered during the world circumnavigation of R/V Jean Charcot . The study of these examples provides a new overview of active margin modelling in response to asperity subduction. It is concluded that both erosion and accretion may be governed by the oceanic plate even though frontal tectonic erosion is better documented because it is accessible to conventional surveys. Most of the time, erosion is due to the relaxation of the arc slope in the wake of asperity/subduction.

In remote control, the master element which the user operates looks for practical and historical reasons like the slave arm and therefore features a series architecture, with a few drawbacks in terms of mass, dimensions, rigidity and mechanical complexity. To remedy these defects, we are now introducing a new master element with parallel kinematics. This syntactor, derived from Steward's manipulators, has six degrees of freedom and comprises six motor-driven links arranged on a fixed plate (the base) and a moving plate on which a 6-axis force transducer and a handle are mounted. The device is made artificially free along a few or all axes by means of a hybrid position/force control software which translates the wrench of forces applied by the operator on...

Une étude hydrobiologique de quatre secteurs ostréicoles a été menée de mars à octobre 1987. Les eaux de la baie de Bourgneuf sont favorables à l'ostréiculture en raison de leurs teneurs en chlorophylle, sels nutritifs et seston. Les caractéristiques hydrobiologiques sont cependant différentes entre les secteur nord et sud, ces derniers présentant des conditions de milieu d'élevage plus stables. Le gradient de richesse phytoplanctonique de la zone intertidale proche du continent est orientée selon la veine principale du courant résiduel des masses d'eau, avec une décroissance marquée du nord au sud. Le secteur le plus nord (S3) est en période estivale une zone à forte probabilité de développement de dinoflagellés durant les marées de vives eaux. La zone du...

Burial of submarine telecommunication cables: Use of ROV.
Provedor de dados: 5
Autores: Dupin, G.
The development of telecommunications and in particular the constantly increasing demand of digital services make the submarine telecommunication cables very strategic and the users of these services very sensitive to interruptions or degraded quality. Then, the main cause of faults on submarine telecommunication cables is trawler or anchor damage. Therefore, once the route has been finalized, only a good quality of burial can reduce the risks linked to these external aggressions. The tools used to-day by France Telecom for burial are: a standard sea-plough, with a share, towed by the cableship simultaneously to the laying operation; ROVs (SCARAB) to post-lay bury cables by jetting, repair buried cables and rebury the cable after repair.

The less evolved stage is represented by the Okinawa basin, where accretion is evidenced only by volcanic intrusion into a thinned continental crust. The most evolved stage is illustrated in the North Fiji basin, where the present-day accretion can be directly compm·ed to the East Pacific Ridge. The Lau basin displays an intem1ediate stage with a complex system of accretionary ridges. This difference in the evolution stage is translated in...

Qualité bactériologique des coquillages sur les zones de production et les gisements naturels du Quartier Maritime de St-Brieuc (Côtes d'Armor) (Bilan de l'année 1988)
Provedor de dados: 5
Autores: Rougerie, Michel; Le Mao, Patrick.
Ce rapport présente le bilan pour 1988 des analyses bactériologiques effectuées sur les coquillages prélevés dans les zones d ' élevage et sur les gisements naturels découvrants du quartier maritime de Saint Brieuc. L'année 1988 a été particulièrement pluvieuse en début d'année ce qui a entraîné des interdictions de commercialisation des coquillages. D'une manière générale les zones de culture de coquillages et les gisements naturels découvrants ne correspondent pas aux normes de salubrité fixées par l'arrêté du 12/10/1976 . Cette mauvaise qualité bactériologique est très préoccupante et est dûe tant à une pollution urbaine qu 'à une pollution agricole.

Observatoires sismiques sur le fond de la mer

Autores: Avedik, Felix.
Detecting and localizing nuclear blasts was an essential stimulus of the actions undertaken in the 1960's to emplace seismological observatories on the seafloor. The plate-tectonic theory, in which the oceanic areas play a major role, greatly accelerated the evolution of modern oceanology. The contribution of Ifremer's department of Marine Geosciences, in helping to advance this area of research, has been significant since 1972. The need for refraction studies to explore the deep structure of the margins and ocean-continent transition zones led us to design a deep-sea Ocean Bottom Seismograph (OBS) MK I in 1975, rated to 6,000 metres depth. This system introduced, for the first time, the concept of "isolated seismic sensors". This principle was adopted...

Marine geophysical surveys using Seabeam, single channel seismic reflection, gravity and magnetic profiling were conducted along the Acapulco Trench (21 degree 30'N-18 degree 00'N) during the Seamat Cruise of R/V Jean Charcot in June-July 1987. The surveyed areas are centered around latitude 18 degree N and 20 degree 30'N across the trench. Detailed surveying was also conducted at the East Pacific Rise (EPR) - Rivera Fracture Zone (RFZ) eastern junction. Unpublished bathymetric data of the Searise Cruise of R/V Jean Charcot conducted at the Western junction of EPR and RFZ in 1980 are also presented.

La collision ride des Loyaute/Arc des Nouvelles Hebrides (Pacifique Sud-Ouest)
Provedor de dados: 5
Autores: Monzier, M; Daniel, I; Maillet, P.
The collision between the 22 degree S salient of the Loyalty Ridge and the southern New Hebrides Arc began some 300,000 years ago. Nevertheless, the ridge probably influences, since 1 to 2 Ma, the subduction at the southern arcuate New Hebrides Trench through its action on the bulge of the downgoing plate. The morphology of the ridge, its deep root and relative buoyancy affect the flexure and the subduction of the downgoing plate in several ways. The proposed effects of this arc-ridge collision may be traced on a regional scale: in front of the collision zone, the southern New Hebrides active volcanic line is weakly developed, the intra-arc troughs are absent, and the Benioff zone is short. On the nearby north Fiji basin, the offset of the southern active...

(Not controled OCR) The economic results of artisanal fishing enterprises are investigated through a sample of 300 to 700 artisanal vessels for which account books. The use of economic (such as added value) and financial ratios (solvency and financial autonomy) leads to identification of four groups of firms. Over the period, financial rentability and autonomy show obvious damaging that underlines the relance of a (current) analysis on the impact of public subsidies on the enterprises behaviour.

The understanding of the processes involved in large climatic changes as the last glacial/interglacial cycle asks for detailed descriptions of the changes which occurred during the last deglaciation, the only transition which may be dated accurately. In that matter, the super(14)C Accelerator Mass Spectrometry (AMS) allows unprecedented sensitivity on the dating of the foraminifera which are used for isotopic analysis. The partial differential super(13)C of the benthic foraminifera is a good indicator of the changes in bottom water ventilation. We present here a comparison of the changes in the oxygen and carbon isotopic records of benthic and planktonic foraminifera in 2 cores from the north west slope of the Pacific Ocean, along the Japan continental...

Introduction Starting in 1986, the ANVAR contributed well appreciated financial support in order to set up an original seeding technique characterized by artificial seeding production in a laboratory. This advantageous new way of seeding, i.e. independency from nature, yield increase and true competitiveness compared to traditional methods, nevertheless requires strict adherence to a procedure progressively elaborated during numerous trials in laboratory as well as at sea. The program ended in July 1989 after testing the cultivation protocol on a 2 hectare exploitation scale, in order to better detect what could be improved to greatly increase productivity, facilitate the work of the harvester and to better adapt the operating mode to environmental...

Sensitivity and variance estimators for virtual population analysis and the equilibrium yield per recruit model
Provedor de dados: 5
Autores: Pelletier, Dominique.
Fish stock assessment makes Widespread use of Virtual Population Analysis (VPA) and long-term equilibrium prediction models. Although there have been some statistical investigations about the properties of VPA results, apparently there are no complete analyse about predictions statistical and numerical behaviour. However, management decisions generally rely upon production forecasts. This paper compares stability properties of VPA and the yield per recruit model with regard to various errors concerning all the input parameters. Robustness fis assessed by means of first-ordo sensitivities whereas variances are inferred from delta-method estimators. Sensitivity of yield per recruit appears to be mainly due to terminal mortality rate and age-specific weights,...

Because of the papers that precede this one and focus on resources and markets, I will limit my topic to the economic aspects of fisheries management, that is, solely to the business of capture. Not because I underestimate the importance of the other levels of the fishing system, but out of a concern not to repeat what my colleagues have explained. I will begin with a brief economic overview of fishing in the member states, by means of simple indicators, and with the goal of bringing to light a certain number of questions. The second part of the paper will deal with fishing management when dealing with the EEC, to examine how important questions are treated and to update a few of the challenges for the future of fishing.

Provedor de dados: 5
Autores: Gilbert, Franck; Galgani, Francois.
A new method for the assessment of several contaminant effects on marine microalgae (Tetraselmis suesica, Skeletonema costatum) has been developped. The method is based on the measure of cells esterase activity using a fluorimetric stain, fluorescein diacetate (FDA). The experiments are performed in microplates using a fluorimetric microplate reader. The different steps of the experiments and the data processing are controlled by an original specific software. Application of the system for rapid ecotoxicological tests (determination of LC 50) and for assessment of environment quality by observation of water samples are proposed.

Two types of stations were occupied: CTD hydrocast stations for water chemistry and continuous vertical profiles of chemical parameters in the upper 200 meter layer (SHET profiles). Selected biological stations were carried out mainly for primary productivity (in situ super(14)C method), phytoplankton biomass and photometric measurements (quantum- and spectroirradiance-meters) in the photic zone. Zooplankton was collected at nearly all the stations of the cruise in order to determine biomass and species composition. A long Peru-Galapagos connecting section with 19 stations was carried out for water chemistry down to 2000 meters.

Echantillonnage des débarquements en criée. Estimateurs des captures et variances associées
Provedor de dados: 5
Autores: Pelletier, Dominique.
Stock assessment models generally rely upon catch analysis. Catches are estimated from the sampling of landings. The evaluation of the variance associated to these estimators allows to study the induced uncertainty on models results and hence on stock management decisions. Moreover, the sampling scheme may be improved by analysing the variance components. The results show that the variance is mainly due to the variability of landings between days. In addition, as assessment models show liUle sensitivity to old age groups, sampling effort could be partially transferred from the corresponding market category to those of major economie interesl.

Effets de la subduction de la ride le sur l'arc des Tonga-Kermadec
Provedor de dados: 5
Autores: Pelletier, B; Dupont, J.
The Louisville Ridge, a hotspot chain, obliquely subducts at the Tonga-Kermadec consuming plate boundary (Southwest Pacific). This ridge has swept the Tonga Trench and the ridge-trench junction point is rapidly (at least 10 cm per year) migrating southward along the Kermadec trench. Results from a comparative morphological study between the Kermadec and Tonga margins, and from the Seapso 5 seabeam survey around the ridge-trench junction consider the effects of the subduction of an oblique ridge on an active margin. Underplating of material scraped and pushed in the front of the ridge could be responsible for the high-standing position of the Tonga platform in the prolongation of the Kermadec active volcanic line.

Autores: Laval, P.
The gelatinous macroplanktonic organisms living in the deep sea can only be studied with manned submersibles. There is presently in increasing interest in the study of the role of this part of the pelagic ecosystem, because they are strongly involved in the transformation of the particulate organic matter. Their transparency, small size and mobility present technical challenges, unanticipated by the designers of the first submersibles, aimed at the sea bottom observation. Despite these limitations, the use of conventional submersibles has brought very interesting results. It is hoped that engineers will take into account the requirements of pelagic observations in the design of future submersibles.

Provedor de dados: 5
Autores: Haure, Joel; Baud, Jean-pierre.
A study on mortalities, growth and fattening of the oyster Crassostrea gigas was carried out spring with the autumn 1987 in four sites of bay of Bourgneuf. Mortalities, more important in spring, prove to be higher in the sectors North compared to the Southern sectors of bay of Bourgneuf.  The performances of growth are rather weak when they are compared with other French oyster sectors. They however present a better production in the cattle-breeding areas located at the South of bay. The spring phase is marked by the formation of glucidic reserves, at the moment of the reheating of water, which is quickly transformed, in the majority of the sites, in lipids of reserves of the ovocytes, during the gamétogenèse.   The state of fattening of Crassostrea gigas...

In July 1988, the first re-access to a deep sea borehole was performed using the logging shuttle NADIA 1 and the manned submersible NAUTILE during the cruise FARE. This operation was conducted on the site DSDP 396 B, drilled by the Glomar Challenger within the framework of the Deep Sea Drilling Project in 1976, close to the axis of the mid Atlantic Ridge at 23 degree N. A temperature logging hole and a fluid sampler was introduced in that hole and lowered to -300 m below the sea floor. It was the first time such an operation was done without a drill string and a drilling ship equipped with a dynamic positioning system. From this experience, a new logging shuttle, NADIA 2, was developed. NADIA 1 was designed with the objective of demonstrating the...

Excessive proliferation of UIva sp. (Chlorophyta) during spring and summer was responsible for increasing injuries to recreational use of several beaches of Britanny (France) during the last decade.

Numerical modelling of the coupled physical and biological aspects clearly explains the Ulva mass blooms by the dynamical trapping of water masses in bays where tidal residual drift vanishes, and shows the main responsability of the increase of nitrogen inputs (of agricultural sources) in triggering the recent magnification of a natural phenomenon.

Structure crustale d'une dorsale lente : tomographie sismique 3D sur la dorsale de Mohn (72°20N, 1°30E)
Provedor de dados: 5
Autores: Lecomte, Isabelle.
The formation of oceanic crust along ridges is not well understood. Geological and geochemical studies of ophiolites and samples dragged on the sea floor introduced the concept og magmatic chamber where the oceanic crust would be created. Classical refraction seismic often had difficulties to determine the velocity structure of a ridge. International research is so going towards seismic tomography.

Geochemical investigation of Pt, Pd, Rh, Ru and Au in cobalt-rich deposits from the Tuamotu Plateau (French Polynesia)
Provedor de dados: 5
Autores: Amosse, J; Le Suave, R.
Pt, Pd, Rh, Ru and Au contents were determined in 35 samples of hydrogenous ferromanganese crusts and nodules from the Tuamotu Plateau (French Polynesia), collected during the Nodco II cruise undertaken by IFREMER during March 1987. These samples are characterized by high Pt and Rh contents. A statistical analysis including PGE and data on Mn, Fe, Ni, Co and Cu contents does not reveal significant correlations between the elements. Although meteoritical origin of PGE remains possible, the process of fractionation and deposition is probably hydrogenetic as confirmed by normalization diagrams to chondrite C1. This point of view is supported by the determination of some partition coefficients of PGE between the oxidized phase and the aqueous medium. The...

Relations entre le contenu lipidique des ovocytes de Pecten maximus (Mollusque, bivalve) et les performances des larves en élevage
Provedor de dados: 5
Autores: Le Pennec, Marcel; Gueguen,.
The lipid content of spawned oocytes of Pecten maximus was studied by image analysis of semi -thin histological sections and a lipid index was defined. The female gametes were obtained by thermic stimulations of mature adults scallops from different populations after out of season conditioning or sampled in situ during the spawning season. After fertilization, the larval development was followed. The results reveal a large variability in lipid content of normal oocytes. The lipid content can be regarded as homogeneous inside a spawning but the heterogeneity is greater for wild scallops than for conditioned ones. A strong relationship appears between the lipid index and the hatching success, and the number of abnormal larvae after two days rearing. But no...

La biocorrosion. Processus caractéristiques et moyens d’études
Provedor de dados: 5
Autores: Guezennec, Jean.
In contrast to the situation of a few years ago, the phenomenon of microbiologically induced corrosion is now generally accepted as being one of a number of mechanisms whereby corrosion occurs. A considerable amount of multi-disciplinary effort has been expended to determine the extent of the problem and to understand the phenomenon. Microbial corrosion refers to the degradation of metallic or non metallic structures resulting from the presence and the activity of a variety of organisms on the surfaces. Although, in many cases, microbial corrosion is closely associated with biofouling phenomena, the area in which it causes most damages concern the deterioration of metallic structures in soils and sediments with the well-known sulphate-reducing bacteria.

Evaluation des stocks d'huîtres (Crassostrea gigas) et des stocks de moules (Mytilus edulis) sur les gisements naturels et en élevage sur bouchots dans la Baie de Bourgneuf (Année 1988)
Provedor de dados: 5
Autores: Baud, Jean-pierre; Lefrancois, Josiane; Haure, Joel.
Les différentes études menées durant l'année 1988 ont permis d'estimer les stocks d'huîtres en élevage à 46 000 tonnes ± 11 % et de moules de bouchots à 940 tonnes ± 25 %. Les stocks sur les gisements sauvages de moules situés sur un axe médian Est-Ouest à l'intérieur de la baie, sont estimés en 1988 à 6 700 tonnes ± 49 %. Ils n'ont pas perturbé la croissance des huîtres élevées en aval comme en 1986. Ces croissances demeurent toutefois faibles par rapport à une zone localisée à l'extérieur de la baie. Suite à la décision d'instaurer des mesures de régulation du cheptel, une tendance à la régression du nombre de collecteurs au mètre linéaire est notée en baie de Bourgneuf. Il reste cependant à réduire durablement les stocks d'huîtres creuses et de moules...

Etude geophysique des dorsales de l'ocean Indien dans la region du point triple de Rodriguez
Provedor de dados: 5
Autores: Munschy, M; Schlich, R.
The Indian Ocean is dominated by as system of 3 mid-ocean ridges converging at the Rodriguez Triple Junction located near 25 degree 30'S and 70 degree E. Numerous studies carried out on these 3 ridges provided the basic information on spreading rates and spreading directions. In 1984 the R/V Jean Charcot conducted a detailed survey over the Rodriguez Triple Junction and over an axial ridge segment located on each of the 3 associated ridges. The ridge axes are cut by distinct rift valleys; the depth of these rift valleys is a function of spreading rates. The rift valleys are not in isostatic equilibrium, but show clear density and mass deficits (0.4 to 0.8 g.cm super(-3) for spreading rate of 1 cm/a and 0.1 to 0.3 g.cm super(-3) for spreading rates of 3...

Responsible for large exchanges between the Ocean and the Lithosphere, oceanic hydrothermalism covers wide scientific domains, from the ocean chemistry to metallogeny. The exploration covers all scales, from the hydrothermal site to the Mid-oceanic ridge system. Modern bathymetry and imagery are required. Physical and chemical anomalies created in the ocean are used to detect and map its distribution. A specific effort in the field of ROV (Remote Operated Vehicle) is needed to acquire data at the corresponding working scale.

Autores: Alayse, Anne-marie.
With the advent of deep submergence research vessels (DSRVs) biological and ecological studies of ocean deeps have made great strides. Especially these submersibles allowed to conduct physiological and biochemical experiments on benthic fauna directly on the bottom or on board with alive retrieved animals. A second great interest is the possibility to work in chaotic areas and on microenvironments. Without DSRVs most of measurements and observations obtained on hydrothermals vents would had been impossible. We will present the different equipment designed for the two French DSRVs used during the cruises conducted by the Departement "Environnement Profond" de l'IFREMER to study hydrothermal and "normal" deep-sea ecosystems. We will discuss the new devices...

Les premiers essais d'aquaculture du bar puis de la dorade remontent aux années 60-70 en Méditérranéenne avec des tentatives de mise en valeur de zones lagunaires (valle en Italie, salines en France et Espagne). L'insuffisance de l'offre de pêche en dépit de la surexploitation des stocks de bars et dorades, l'existence de marchés connus, la valeur commerciale élevée de ces produits incitent à la recherche de techniques d'élevage adaptées à ces espèces.

Salient geological results from the Biocal cruise are based on 3.5 khz echosondeur profiles. Slopes morphology is controlled by tectonics and erosion/sedimentation balance. From Thio to Lifou, an uniform basin bottom is depressed southwestward by tectonic subsidence and uneven northeastward by a tectonic ridge (the Levi Ridge). Sedimentation is fed by 5 main sources: Great-Land of New-Caledonia, yielding an important terrigenous flux, reefal barriers surrounding it and raised reefs of Loyalty islands, benthic communities dwelling on slopes and in the basins, plankton and volcanoes of New-Hebridean arc. The development of Quaternary reefal barriers around islands of the new-caledonian archipelago has reduced severely the input from emerged lands and...

Polyploidy in the Manila clam Ruditapes philippinarum. II. Chemical induction of tetraploid embryos
Provedor de dados: 5
Autores: Diter, Alain; Dufy, Christian.
Tetraploidy was induced in embryos of Ruditapes philippinarum by treating the eggs with cytochalasin B. (CB). Two treatment times were found to be effective in inducing tetraplidy : 0 to 10 minutes after insemination (before formation of the first polar body) and 45 minutes after insemination (just before the first cleavage). Treatments, started 5 and 45 minutes after insemination, produced 64.4 ± 7.8% and 28.3 ± 2.3% tetraploid embrios, respectively, after 6 hours (on the average over 3 experiments). However, no tetraploids were detected in 4-month-old spat. Sperm entry delayed by the CB could be involved in induction of tetraploidy by early treatment.

The continuous obtention of current (speed and direction) turbidity and phytoplanktonic   fluorescence was achieved for 9 successive days during the month of May 1988. Each two hours, during the day, the faeces and pseudofaeces productions of 7 oysters have been sampled individualy. The filtration rate were calculated in continuous. It appeared that the concentration in particular matter and also the planktonic fluorescence fluctuated in direct relation with the water depth, the origin of the water masses and the speed of the wind. During the tidal cycle the mean filtration rate was constant which induced a food consumption largely variable. The oysters were always above the limit of pseudofaeces production which regulated the ingested quantity. Their...

Mass mortalities of oysters (Crassostrea gigas) during spring 1988 in the Bay of Marennes-Oleron, related to environmental conditions
Provedor de dados: 5
Autores: Bodoy, Alain; Garnier, Jacqueline; Razet, Daniel; Geairon, Philippe.
Mass mortalities of oysters were recorded in the South of the Bay of Marennes-Oleron, during spring 1988. The percentages of mortality averaged 50 % and reached up to 90 % in some areas of bottom culture. The losses were estimated to 7 800 tonnes. This paper present the results of the investigations carried out in several fields. Among them, pathological examination revealed that no pathogenic agent or parasitic infestation could be evoked to explain these mortalities. Analyses of pollutants were either negatives, or the concentrations were far below the toxicity levels. Climatological and hydrological observations showed that rainfalls were twice more abundant then the average, for a period of 6 months preceding the mortalities. The salinity was low and...

Infrared measurement at the sea surface, which constitutes an operational technology in remote-sensing, has become essential for the study of ocean dynamics. Nevertheless, observations are only usable when clouds do not mask infrared radiation coming from the ocean, a condition which rarely pertains in the Bay of Biscay as a whole. lt is consequently a matter of primary concern to have at one's disposai an effective method which permits the computation of mean SST fields from a chronological succession of incomplete images. In the case under consideration, "kriging" is the most widely practised method of performing geostatistical estimates. Before mapping isotherms, temperatures are estimated by interpolation on a regular gridnet. The process was applied...

Variation des sources de sediments dans le detroit de Makassar (Indonesie) au quaternaire recent: Role des facteurs morphostructuraux et eustatiques
Provedor de dados: 5
Autores: Faugeres, J-c; Gayet, J; Gonthier, E; Latouche, C; Maillet, N.
Mineralogical analyses of sediments from the Makassar Strait, collected during the Corindon and Misedor cruises (dredges, piston and box cores) show the existing differences between sediments supplied from Kalimantan in the West and sediments supplied from Sulawesi in the East. The Kalimantan source is characterized by quartzitic sand, with rare feldspars, heavy minerals consisting mainly of pyroxene (hypersthene) and amphibole and predominant illite-kaolinite in the clay mineral assemblage. In contrast, the Sulawesi source differs by a great abundance of feldspars, lithoclasts and micas with predominant amphibole and pyroxene (augite) and major illite-chlorite clay minerals.

Environmental and species features which lead to increases in cell density of the D.S.P. Dinoflagellate Dinophysis in inshore and offshore waters of the île de Ré - île d'Oléron area, France (cruises "Dinopertuis89"). Four weekly sampling series have been carried out, within 10 May – 31 May 1989, at 24 stations located from inshore to offshore waters of the "île de Ré" - "île d’Oléron" area, with the aim to investigate (i) whether Dinophysis increases in cell density occur first in offshore waters and then, eventually, are pushed to the coast, or develop simultaneously in the whole area, and (ii) whether there are some environmental conditions which are related to Dinophysis blooms. Depths of sampling have been stated on the bas is of STD profiles. All...

Stock characteristics of Atlantic salmon (Salmo salar) in France: a review
Provedor de dados: 5
Autores: Prouzet, Patrick.
The general characteristics of the main salmon (Salmo salar L.) stocks in the Massif armoricain (Brittany and Lower Normandy), in the Loire-Allier and in the Adour-Gaves-Nive have been summarized. Due to the poor quality of the previous fishing statistics, there is no clear picture of the historical evolution of the salmon stock. However, a dramatic decrease in the endemic range of Atlantic salmon in France can be shown since the mid-18th century a nd more particularly during the last 50 years. The lack of precise informations describing the size of the catches and the levels of exploitation at sea and in the estuaries make it impossible to estimate the impact that exploitation has led on the evolution of salmon stocks. The mean age of salmon in freshwater...

The side looking sonars have been developed for greater swath coverage, digital processing of the signals has improved the quality of the images and interferometric techniques have been used to determine the depth of the bottom features. A review of the systems existing today is presented. Documents such as graphs, block diagrams, images, maps, sections, created from data acquired at sea level suffer from a filtering or smoothing effect that restricts the representativity of the measured parameters and therefore limits their interpretation. The greater the depth of the seafloor, the greater the filtering. It is due not only to the nature of the measured phenomenon but also the characteristics of the sensors, to their operation and to the data processing....

Methods of gynogenesis, androgenesis and polyploidy induction were developed with the aim of genetic improvement in the rainbow trout, the Pacific oyster, the Manila clam and the black scallop. In the trout: · haploid androgenesis was induced by means of a pressure shock applied on diploid eggs, probably at the time of karyogamy. Diploid androgenetic individuals were directly produced from eggs fertilized with sperm from tetraploid male. · a heat shock treatment effective for suppressing the first egg mitosis was developed. This treatment allows the production of homozygous gynogenetic lines (checked using enzyme electrophoresis technique) from eggs inseminated with ultraviolet irradiated sperm. The treatment also induced tetraploidy in eggs normally...

By using electrochemical measurements and bacteria counting, we have verified that the added elements in an AISI 316L stainless steel, as poison allowing elements for the bacteria, like copper or arsenic, change the electrochemical properties versus the time, and modifie the structure of the bacterial population on the surface. Comparisons of the obtained results in synthetic sea water, sterilized or inoculated, and in natural sea water have permitted to observe very great differences versus the added elements. The use of sterilized natural sea water and then inoculated, gives results which permit to show the specific role of the aerobic and the anaerobic bacteria.

Optical and geochemical study of organic matter in present oxic sediments (Equatorial North Pacific Ocean Nixo area)
Provedor de dados: 5
Autores: Lallier-verges, E; Alberic, P.
Optical (palynofacies) and geochemical (C, N, amino acids) study of surface sediments from the Equatorial North Pacific Ocean, which are deposited in an oxic environment and characterized by ferromanganese nodule occurrence, revealed figured remains of pelagic, benthic and terrestrial organic matter. These organic remains consist of a residual organic fraction, related to alteration phenomena. The scarcity of amorphous organic matter contrasts markedly with anoxic sediments. Amino acid comparison between hand-picked figured organic elements and bulk sediments indicates that coarse components have distinct compositions, some being biologically active sites; the preserved amino acid content of bulk sediments being mostly related to fine fractions as clays.

The Krakatau project has been launched as a regional study along the Indonesian island arc aiming at understanding the response of an island arc and of its fore-arc to an increased obliquity in the convergence along its subducting border. Along the Sunda island arc, convergence varies from near-to-normal along Java to increasingly oblique along Sumatra, and to near-to-tangent along the Andaman-Nicobar ridge. As a result of this increased obliquity, it has been assumed that the fore-arc region has been mobilized, as a whole as a series of segmented units with a resulting strike-slip motion parallel to the island-arc.

The Rodriguez Triple Junction (RTJ) corresponds to the junction of the 3 Indian Ocean spreading ridges. A detailed survey of an area of 90 km by 85 km, centered at 25 degree 30 degree S and 70 degree E, allows detailed mapping (at a scale of 1/100,000) of the bathymetry (Seabeam) and the magnetic anomalies. The Southeast Indian Ridge, close to the triple junction, is a typical intermediate spreading rate ridge (2.99 cm/a half rate) trending N140 degree . The Central Indian Ridge rift valley prolongs the Southeast Indian Ridge rift valley with a slight change of orientation (12 degree ). The half spreading rate and trend of this ridge are 2.73 cm/a and N152 degree respectively. A model is proposed to explain the evolution of the unstable RRF Rodriguez...

The historical landings of the oyster production are described for the Maryland part of the Chesapeake Bay. The different trends are analysed concurently with the main events and management strategies which occured on the bay. Three main periods are identified : - the greatest fishery from 1840 to 1890 with a large overfishing and the destruction of the oyster habitat caused by the oyster gears, - the decrease and stable landings from 1900 to 1980 due to the failure of the reseeding plan connected to the heavy sedimentation and the anoxic summer conditions, - the large decrease of the production (1981-1988) caused by high mortalities related to diseases (MSX and Perkinsus marinus) prédation and management practices.

Influence de l'apport de la Charente sur la qualité bactériologique des eaux de l'estuaire - Campagnes 1988 et 1989
Provedor de dados: 5
Autores: Masson, Daniel; Faury, Nicole; Ratiskol, Jacqueline.
Le bassin de Marennes Oléron, comme toutes les zones conchylicoles, est susceptible d'être touché par les apports pollués. Dans ce domaine, le vecteur potentiel que constitue la Charente méritait d'être étudié plus particulièrement, la qualité bactériologique des eaux pouvant affecter par la suite la salubrité des coquillages. L'étude précédente (Masson et al. 1988) a fait apparaître que la pollution bactérienne apportée par la Charente (particulièrement en étiage) sédimentait rapidement, la quantité de germes devenant très faible à la sortie de l'estuaire. Toutefois, comme l'enjeu économique est important (perspectives européennes) il était nécessaire de confirmer ce résultat avec un système de suivi identique à celui utilisé en 1987. De plus, un certain...

Traitement du sédiment contaminé par le vibrio P1 : effet d'un antiseptique sur la palourde Ruditapes philippinarum, la faune et la flore benthiques
Provedor de dados: 5
Autores: Calves, Magali.
Since 1980, the clam's farming in Brittany (Ruditapes philippinarum) has increased. But unfortunately in 1986, a high mortality especially in the "Aber" area (Nothern Finistere) was observed. The origin of this is a "brown ring" inside the shell caused by a pathogenic agent : a vibrio : vibrio Pl. The therapetic investigations was carried out with two objectives : on one hand to treat the clams, and on the other hand to eradicate the vibrio from the sediment of the rearing area. We got good results in vitro for this former treatment with an antiseptic called "Agroseptil" at the level of 40 ppm of active molecule.Before using "Agroseptil" on a large scale, toxicity was tes ted in the field and in laboratory. There tests were carried out on clams and on...

Etude expérimentale du pouvoir pathogène de bactéries du genre vibrio isolées dans la région Nord Pas de Calais
Provedor de dados: 5
Autores: Herdandez, Jean-françois; Daubelcour, Christine.
Des travaux effectués dans notre laboratoire (Hemandez 1989) ont permis d'une part le développement d'une méthode en microplaque, simple et rapide, pour le dénombrement des vibrions et d'autre la sélection critères phénotypiques permettant une identification présomptive, au niveau de l'espèce, des vibrions halophiles. Cette méthodologie a été appliquée sur le site de la centrale thermonucléaire de et sur littoral Nord - Pas de Calais. Elle a d'ores et déjà permis de confirmer que ce groupe microbien y profite de l'échauffement eaux et des rejets de matières organiques. D'autres facteurs comme la saison, la dessalure ou l'apparition de blooms phytoplanctoniques peuvent modifier la répartition des espèces à l'intérieur du groupe. Associées à V. alginolyticus...

The Teahitia-Mehetia hot spot region located in the southeastern extension of the Society Islands chain, near 18 degree S-148 degree W consists of several active volcanoes. The distribution of recent volcanic activity correlates with seismic epicenters, and covers an area of more than 1000 km super(2). Intermittent volcanic activity has given rise to large (&gt; 1000 m high) and small (&lt; 500 m high) edifices composed of various types of flows. Several recent volcanic events have produced a suite of alkalic rocks ranging from ankaramites, through alkali basalts to trachyphonolites. The presence of altered MORB-like tholeiites on one small seamount suggests that a different mantle source material was involved in forming some of the crust in this hot spot...

Detection de fissure sur structure en mer en presence de salissure marine projet "Crabe"
Provedor de dados: 5
Autores: Daste, S.
The "CRABE" method is a crack detection technique based on the use of low electromagnetic frequencies. This (patented) method relies on a global injection of current within the structure under inspection. The presence of a crack shall cause a disruption in the current flow, and consequently of the magnetic field off the surface in the vicinity of a defect. It is this magnetic signature which is detected by the magnetic sensor used with "CRABE". The major advantage of this process, developed by TRAVOCEAN and the LETI Division of CEA with the help of IFREMER, appears clearly: No preliminary cleaning of the welds to be inspected is required, since no contact is necessary. Similarly, it shall be possible to inspect the whole of structures to a total cost all...

Autores: Maguer, Jean-francois.
Des mesures de cuivre total dans les sédiments de quelques estuaires bretons ont été réalisées. Il a été trouvé une relation directe entre le cuivre et la granulométrie, les concentrations les plus élevées correspondant aux granulométries les plus fines. La relation entre le cuivre et la matière organique n'est pas évidente. Il semble que les concentrations en cuivre sont en relation avec le rapport : porcs (sauf petits en lactation) / surface cultivée, dans les cantons où ont été faits les prélèvements.

Hydrofast Cruise of the R.V. Jean Charcot addressed the important problem of the variation of hydrothermal activity along the strike of the Ridge over a distance of 100 km with respect to the structure of the ridge axis. This cruise was conducted along the East Pacific Rise between the OSC at 11 degree 45'N and the topographic high at 13 degree N. To reach that objective, a new tool, the dynamic hydrocast, was used. This technique obtains average samples mile per mile, horizontally, at 4 different depths above the bottom. Temperature is recorded at the same time. In addition, the side-scan sonar SAR gave a continuous picture of the fissures along the strike and of the different facies within the 300 to 400 m width of the axial graben. A magnetometer and a...

Avec l'accroissement démographique, le volume des eaux résiduaires déversées quotidiennement dans l'environnement marin a atteint des niveaux considérables. Le littoral marin reçoit, en effet, les eaux usées provenant des émissaires des agglomérations littorales, les eaux fluviales et d'estuaires utilisées parfois pour les rejets domestiques, et les eaux de ruissellement terrestre pouvant entraîner détritus et déchets animaux. D'une manière générale, ces eaux résiduaires renferment des matières organiques en grande quantité, des micropolluants (détergents, hydrocarbures) mais surtout des micro-organismes apportés le plus souvent par les matières fécales. En dépit de leur traitement au niveau des stations d'épuration, leur concentration en bactéries reste...

Autores: Greger, B.
A conceptually new, modularly designed exploration system for the deep sea (600 m) has been constructed and tested. In its base unit, different soil sampling tools can be integrated. These are, for the time being, a drill core barrel with 0 48 mm iD and a length of 500 mm for rocky basements as a box corer for softer soils as well as an orange peel grab. Towed along via a coaxial cable from a research vessel, the system is TV-guided and can be actively positioned by means of 2 thrusters in order to be lowered precisely and horizontally levelled on the seafloor. The total system is operated by the help of an onboard computer and may be controlled by sensor displays and operation messages. Microprocessors control the underwater unit which is partially...

Autores: Mauffret, A; Jany, I.
During the Seacarib Cruise the region south of the Greater Antilles (Hispaniola and Puerto Rico) has been investigated. During this survey we recorded continuously Seabeam, magnetic, gravity and seismic digitized data. The Muertos Trough disappears toward the west where the Beata Ridge reaches the trough. The volcanic rocks outcropping in the Southern Peninsula of Haiti and those of Beata Ridge have the same composition. These oceanic rocks and the emergence of the Muertos prism suggest a collision between Beata Ridge indenter and the northern block of Hispaniola. The Caribbean Plate has an eastward motion relative to the America Plate; however the crushing of the northern Hispaniola Block between two jaws, Beata Ridge and Bahamas Bank, leads to the...

Campange Misedor: Etudes sedimentologiques et geochimiques du detroit de Makassar (Indonesie)
Provedor de dados: 5
Autores: Gayet, J.
The aim of this oceanographic cruise, included in this GIS MISEDOR project was to study the distribution and evolution of the organic matter in the Strait of Makassar, within a distance ranging from the Mahakam delta to the abyssal plain. The particularity of the strait lies in its morphostructural aspect and climatic trend. It is a half-closed basin situated at the far end of the Asiatic (passive margin of Borneo) and Indo-Australian plates (active margin of Sulawesi). Its geographical proximity to the Equator accounts for the very few climatic variations during the Quaternary, a period characterized only by glacio-eustatic fluctuations of the sea level.

Campagnes Kaiko (legs 1 a 3): Divers aspects de la subduction dans les fosses japonaises
Provedor de dados: 5
Autores: Pichon, Xle; Renard, V; Cadet, J P.
Many scientists have participated at these Kaiko cruises. Three legs have been studied. The observations show that the trenches around Japan exhibit a whole range of possible subduction processes. It has been demonstrated that the subduction could fairly "swallow" as sharp-pointed fishbones as volcanoes as Fuji Yama or as big lumps as the palau Kyushu volcanic arc. The subduction then changes into collision and these surveys provide the first indications about the way. The transition from the Nankai trench to the Izu collision takes place. Such transition is accompanied by an oceanic lithosphere overthrust. Last, it appears that scars exhibited by the oceanic lithosphere in the form of fossil rift valleys and faults are reactivated upon the bending of the...

Estimation du captage d'huître Crassostrea gigas dans le bassin d'Arcachon de 1985 à 1989
Provedor de dados: 5
Autores: Maurer, Daniele; Borel, Michel.
Les conditions très favorables à la reproduction de l'huître dans le bassin d'Arcachon, lui ont donné traditionnellement une vocation de centre de captage. Cette activité, très perturbée durant 5 années consécutives (peintures antisalissure à base d'organostanniques), a retrouvé son cours normal depuis 1982. Il est donc apparu intéressant de faire le point sur l'importance du captage réalisé dans le bassin, du fait de ses répercussions à la fois sur la vente de naissains et sur le recrutement de la population de Crassostrea gigas en élevage. Les estimations ont été menées durant 5 années, de 1985 à 1989, selon différents plans d'échantillonnage.

Three cruises (POP 1, SEAPSO 3 and SEAPSO 4) carried out during the "Tour du Monde" of the R.V. Jean Charcot allow us to obtain new structural and geochemical data for the Okinawa, North Fiji and Lau basins. Taken together, the structural and geochemical data illustrate a difference in evolution stages of these sites. The less evolved stage is represented by the Okinawa basin, where accretion is evidence only by volcanic intrusion into a thinned continental crust. The most evolved stage is illustrated in the North Fiji basin, where the present-day accretion can be directly compared to the East Pacific Ridge. The Lau basin displays an intermediate stage with a complex system of accretionary ridges. This difference in the evolution stage is translated in the...

Autores: Lancelot, Y; Froger, V; Cheminee, J L; Galisson, H; Larson, R; Mauffret, A; Schlanger, So; Sclater, J G.
The Mesopac Cruise was the first multichannel seismic study of the western basins of the Pacific Plate. It was concentrated in the Nauru Basin and in the western area of the Central Pacific Basin. Profiles were calibrated with drilling results from DSDP Sites 462 and 169. For the first time one could observe reflectors within the Cretaceous volcanic complex down to approximately equals 8.5 seconds. Profiles did not allow direct observation of the top of the oceanic crust. After correcting for the load on top of the oceanic crust, results suggest that it cannot lie much deeper than those reflectors. If the oceanic crust lies only a few hundred meters beneath the 2.4 km thick complex, it would be right on the normal thermal subsidence curve corresponding to...

A zoological survey of all macrofauna of benthic Invertebrates has been made along the slopes. New taxa of all taxonomic ranks are abundant. High faunal specific diversity and originality is obvious to all taxonomists. It is worth to mention that since the "Challenger" expedition over a century ago, the whole south-western Pacific region has been kept away from the great deep-sea research vessels routes. The study of both the BIOCAL collections and all the others from further cruises around New Caledonia is insured to provide new data to understanding the biogeography and evolution of the deep sea fauna.

Added water in frozen scallop muscles french specifications and methodology
Provedor de dados: 5
Autores: Loreal, Henri; Etienne, Monique.
The problem of foreign or added water is not really specifie of scallop muscles. Nevertheless, the astonishing ability of scallop muscle to soak up water makes the problem keen.  Heavy water additions that bring about excessive loss of water when thawing scallops are clearly a falsification.  Frequent abuses have been established in France in the 1980-1986 years, much so that the product might depreciate in the eyes of the consumers.  Consequently French importers and administrations decided to elaborate a standard in order to eliminate excessively soaked scallops and to preserve the brand image of the product.  Three points are defined in this standard :  . a sampling plan (codex plan NQA 6,5 S3) . the water/protein ratio on deglazed scallop muscles as...

Suivi des efflorescences phytoplanctoniques en Charente-Maritime en 1988
Provedor de dados: 5
Autores: Burgeot, Thierry; Fillon, Alain; Ratiskol, Gilles; Vayne, Jean-jacques.
La synthèse des informations collectées en 1988 en Charente Maritime, en matière de développement microalgaux a pour but de mettre en évidence, à partir des données recueillies au cours d'une année, des tendances et niveaux de contaminations phytoplanctoniques, ainsi qu'une certaine identité du secteur surveillé. L'année 1988 est marquée par une efflorescence monospécifique de Gymnodinium sp. en période estivale et par l'apparition du Dinophysis à des concentrations supérieures au seuil toxique sans qu'aucne toxicité ne soit décelée. Le réseau de suivi confirme, à travers la bonne représentativité des stations de prélèvement, la spécificité des pertuis charentais

Development of culture techniques for new bivalve species
Provedor de dados: 5
Autores: Bodoy, Alain; Mercer, J. P.
Were are two main reasons for the development of cultivation techniques of new  bivalve species. First, the risk exists that traditionally reared species may be ereadicated or severely depleted by pathogenic agents. For example the Portuguese 0yster  Crassostrea angulata. disapeared from the French coasts in the early 1970's and worldwide production of the flat oyster, Oslrea edulis has been dramatically reduced by the effects of Bonamia.  Secondly, in some countries production may he self-Iimiting by the size and availabilily of national and international markets and a wider species range could offer some promising new economic opportunities for aquaculturists. In particular this applies to species where there are identifiable market shortfalls.

Dans le cadre d'un programme de recherche financé partiellement par la région Poitou-Charentes, un élevage expérimental du pétoncle noir, Chlamys varia, a été réalisés dans deux sites aquacoles. L'un concerne la mer ouverte, au moyen de filière d'élevage de type subflottant, l'autre les bassins en terre du marais maritime (claire). Une production en écloserie et un prégrossissement intensif ayant été réalisé, le naissain d'une taille d'environ 18 mm a fait l'objet d'un élevage hivernal, selon un plan expérimental qui comprenait un facteur relatif au milieu d'élevage et un facteur relatif à la densité. D'importantes mortalités ont été constatées juste après la mise en élevage. Elles semblent être en relation avec le transfert des individus entre le site de...

As the third millennium draws near, industrial societies are becoming aware of the limits of what they can do to constrain the biosphere, ending up where "primitive" societies left off.  If the perverse effects of a century of technical revolution and economic expansion are above all perceptible in the area of multiple contaminations that put in danger the well-being of people, environments and in a general way the biosphere's functioning, they also concern the standardisation of products and landscapes and overinvestment in the means of exploiting resources (inputs increasing more rapidly than outputs, when they are not bringing about their decrease).  The search for solutions to the growing imbalance of the relationships Man – Nature – Resources cannot...

A method for optimal analysis of fields with spatially-variable mean
Provedor de dados: 5
Autores: Le Traon, Pierre-yves.
This brief report addresses the problem of objective analysis of fields with spatially variable mean. Conventional objective analysis is confined to fluctuations, where the larger scale is assumed to be known; this report shows how to use the method described by Davis (1985) to estimate simultaneously a large-scale component and a mesoscale component with an accurate error budget. The extension to multivariate analysis is also discussed. The method is then applied to simulated data; this illustrates its contribution in relation to conventional objective analysis.

Polyploidy in the Manila clam Ruditapes philippinarum - 1 - Chemical induction and larval performances of triploids
Provedor de dados: 5
Autores: Dufy, Christian; Diter, Alain.
An effective treatment using catochalasin B (1 mg CB/ml dimethylsulfoxyde in 1 litre of sea water) was developed to induce triploidy in the Manila clam Ruditapes philippinurum (Adams and Reeve). The percentage of induced triploidy was assessed by karyological examination of embryos and spat. The treatment was found to be optimal between 20 to 35 minutes post-insemination exposure to CB, at 25'C, and produced 75.8 ± 5.7% triploid embryos on the average over four experiments. Growth and survival of larvae to metamorphosis were recorded for two different rearings each split into two replicates. Both larval rearings showed similar survival up to settlement: 19.3 and 27.0%, on average over two replicates, in the treated batches relative to the controls. Mean...

Autores: Flores-hernandez, Domingo.
When an important oxygen defficit occurred in the bottom waters of the Vilaine bay during 1982 summer, a great mortality rate of conger eels pointed the failures of our knowledge about the biology and of the ways of exploitation of this stock. This study tries to improve our data about these two topics. Counting of the otoliths rings is relevant for age determination. The length frequencies inside age groups 5 to 11, show two groups with different mean sizes. These two populations are understood as a growth difference between sexes. Females reach 2 metres, but males only 1. The catches sex-ratio point out that the female ratio is more important than the male one. This means changes into distribution area by sexes, with females in shallow waters. The...

Evolution des concepts d'exploitation miniere en mer
Provedor de dados: 5
Autores: Bivaud, J.
At present, offshore placers are generally exploited by means of traditional dredging equipment. This technique, called the "vertical method," consists of working the seabed directly from the surface support vessel through a rigid upflow pipe equipped, when necessary, with a sediment preloosening system. In contrast with the vertical method, this approach is based on the principle of working along the seabed with transfer of spoil up to the surface after extraction. We therefore call this the "horizontal method." Although it varies according to sites, in most cases this method comprises the design of a vehicle, self-propelled to some degree, which moves along the seafloor, carries and operates the appropriate mining tools and includes a system to transfer...

Autores: Catherine, Martial; Blateau, Dominique; Mazurie, Joseph; Le Bec, Claude.
La recrudescence du ver Polydora dans les coquilles d'huîtres creuses observée dès l'été 1988 a pour principale conséquence le développement parfois très important de formations variqueuses et des chambres à vase à l'intérieur des huîtres, ce qui est très préjudiciable à leur qualité commerciale. Le bilan de l'infestation des coquilles d'huîtres par le ver Polydora sur le littoral normand et atlantique en mai et juin 1989 montre que les secteurs ostréicoles les plus touchés se situent à proximité de la Loire et de la Vilaine. Divers traitements des huîtres contre le Polydora sont possibles. Les meilleurs résultats sont obtenus par la combinaison de l'action de la saumure et d'un assec de 24 heures.

Autores: Guennegan, Yvon.
INTRODUCTION : « The fishing industry is still flourishing » but in Corsica as elsewhere, it has already been declining; sea floors are getting depleted. Several vessels have laid up. Where are we in 1989? Corsica fishing is strongly seasonal. The bulk of the activity takes place from spring time to early fall and focuses on bottom fish and sea crayfish. Three types of fishing can be identified: - Trawl fishing on the eastern coast plateau, (16 trawlers). - Trammel fishing to catch rock fish and sea crayfish on the western coast of the island (300 low power and tonnage ships, i.e. 50 KW and 4TJB). - Pond fishing (a few small units). Total catching amounts to roughly 1 000 tons. The fishing fleet is very dispersed along 1 080 km of coast and sometimes faces...

Structure and morphology of the submarine flank of an active volcano: Piton de la Fournaise (Reunion Island, Indian Ocean)
Provedor de dados: 5
Autores: Lenat, J-f; Bachelery, P; Bonneville, A; Galdeano, A; Labazuy, P; Rousset, D; Vincent, P.
In 1984, a Seabeam bathymetric survey and the measurement of the gravity and magnetic fields of the submarine east flak of Piton de la Fournaise were carried out with R/V Jean Charcot . Piton de la Fournaise, one of the most active volcanoes in the world, is a basaltic shield volcano which occupies the southeastern thirdt of Reunion Island in the southwestern Indian Ocean. Most recent volcanic activity occurred within the youngest caldera and along two volcanic rift zones, which trend northeast and southeast and extend beyond the seashore. Three main types of volcanic or volcano-tectonic features have been identified on the Seabeam map. The results show that the history of Piton de la Fournaise is characterized by very large episodes of landsliding.

Elle a considérablement étendu son aire de répartition, en partie grâce au vecteur que constitue le naissain d'huître japonaise Crassostrea gigas (Thunberg). A l'heure actuelle, sa répartition mondiale concerne, en dehors des côtes du Japon, de Chine et de Corée, la côte Ouest l'Amérique du Nord, de Vancouver au Nouveau Mexique (Norton, 1981), les côtes atlantiques de l'Europe et la Méditerranée occidentale française.

Nowadays, side-looking sonar is the only equipment able to carry out long-range underwater imaging. The use of optics is limited to short-range identification by means of conventional video-cameras. However, active optical systems (lidars) manufacturing, using a blue-green laser, will enable optics to hold its place in the field of long-range underwater imaging. After a short comparison between acoustics and optics in underwater detection and a description of the proper features of underwater optical propagation, we present the different conceivable imaging principles and propose a method to determine their performances. The experimentations described concern a lidar imager mock-up using one of the imaging principles proposed. The pictures obtained deal...

Les intoxications humaines résultant de la consommation de coquillages sont connues en France depuis plusieurs siècles. On peut supposer que la cause principale a d'abord été d'origine bactériologique, eu égard aux conditions de transport et à l'absence de contrôles de salubrité dans le passé. Quoi qu'il en soit, il faut compter aujourd'hui avec une autre origine, à savoir les proliférations de certaines algues unicellulaires planctoniques (phytoplancton), qui causent dans notre pays jusqu'à plusieurs milliers d'intoxications par an. Soulignons que la France a été jusqu'ici largement épargnée, puisque d'autres pays comptabilisent des dizaines ou centaines de décès depuis le début du siècle.

Introduction: Setting up a policy of coastal fisheries management goes through a preliminary stage of understanding the dynamics of the fishing fleets as much as their tactics.  Small fleets, such as those of the Côtes d'Armor, are characterised by: - the boats' home ports are scattered widely, - the heterogeneousness of the types of vessels and fishing gear used,  - the versatility of the fishing units, - the plurispecificity of the exploited resource, - the flexibility of operating strategies, that is, the fishing owners' ability to change occupation. However, this flexibility is limited by the availability of the resource, by the market, by the investments granted (boats, fishing materiel), as well as by "cultural" context and know-how.   This...

1988 s’avérait être, pour le bassin d'Arcachon, l'année d'un réel départ de l’élevage de la palourde Japonaise Ruditapes phillipinarum. Cinq millions de naissains étaient ainsi ensemencés, principalement au printemps, soit 4 a 5 fois plus que les années antérieures. La récolte théorique aurait dû avoisiner 50 tonnes en 1990, soit 1/10 de la production nationale . Or d'importantes mortalités étaient signalées au cours de l’été 1988, 80% environ du cheptel ensemencé ayant été touché.

L'aquaculture marine est une activité pratiquée à l'échelle mondiale qui concerne un nombre relativement limité d'espèces de poissons, mollusques et crustacés. Consécutivement aux progrès zootechniques et notamment à la maîtrise des cycles complets d'élevage, les productions aquacoles se sont développées, en particulier celles issues d' écloseries. Cependant, quelle que soit l'espèce considérée et quelles que soient les techniques d'élevage, la pathologie infectieuse constitue un aléa majeur pour les productions, les maladies à caractère épidémique ou endémique étant le plus souvent provoquées par des protozoaires intracellulaires, des bactéries ou des virus. Parmi les viroses, la famille des Iridoviridae pose problème chez un certain nombre d'espèces de...

The major purpose of the Estase cruise has been the coring of the high sedimentation rate sediment, along the continental slope of Japan (Estase I 03 09 84 to 17 09 84) and Philippine islands (Estase II 14 11 84 to 08 12 84), in the north-west Pacific Ocean. Two main scientific objectives were involved in this operation: High resolution paleoclimatology and paleoceanography of the eastern side of the Asian continent, by micropaleontological and isotopic studies of fossil foraminifera, and palynology of the wind and river transported pollens from the continent, and a detailed study of the paleovolcanism, by tephrochronology.

Mise au point technique de l'élevage de l'ombrine Sciaenops ocellata. Document 5 : Le grossissement
Provedor de dados: 5
Autores: Soletchnik, Patrick; Goyard, Emmanuel; Thouard, Emmanuel.
Aux USA, et plus particulièrement en Caroline du sud, l'étude de la croissance de l'ombrine, a commencé dès 1947, à partir des populations naturelles retenues dans les marais salants (Lunts 1951, d'après Smith et al, 1985) puis se sont poursuivies (Theling and Loyacano 1976), également en Louisiane (Beckman et al, 1988 ; Boothby et Avault, 1971 ; Bass et Avault, 1975). En élevage, très peu de données existent sur les performances de croissance de cette espèce jusqu'à une taille commercialisable. Hopkins et al, (1987) fait part de quelques résultats en bassin de terre. Peu de travaux existent sur les besoins alimentaires de l'espèce (Daniels et Robinson, 1986 Williams et Robinson, 1988, Robinson, 1988). Dans le cadre du programme de mise au point technique...

La contamination de l'étang de Bages-Sigean par le cadmium - Première évaluation
Provedor de dados: 5
Autores: Claisse, Didier; Boutier, Bernard; Aranda, Alain.
High levels of cadmium in soft parts of mussels from the Bages-Sigean pond (located to the south of Narbonne, France) have been identified by the National Chemical Monitoring Network (Réseau National d'Observation de la Qualité du Milieu Marin, RNO). To explain this situation, a sampling of water, sediments, and mussels was organised in April 1990. Very high concentrations of dissolved cadmium have been measured in the pond waters and in some of its drainage basin canals (32.4 to 998.0 ng.l-1).  This heavy contamination seems to come from an industrial zone located along the Tauran canal, above Narbonne, and shows the same exceptional feature than the pollution of the Gironde estuary.

Manipulator requirements for NDT (ROV characteristics and the NDT tooling).
Provedor de dados: 5
Autores: Duncan, N.
Pressures of economics are driving the ROV industry to develop NDT equipment which will allow the ROV to detect, and assess, the presence of fatigue induced surface breaking defects in nodal welds and their associated heat affected zones. Two main techniques of NDT are currently being developed by Comex to provide ROV services to meet client needs. One is an MPI system and the other an Eddy Current system. Both are derivatives of equipment currently being used successfully by divers in the North Sea. The two systems are complementary to each other rather than in competition and offer a high degree of defect evaluation. This paper will discuss the requirements placed on the tool deployment system by the task, the worksite, the ROV characteristics and the...

Returns and fishermen income in the artisanal fisheries : a review
Provedor de dados: 5
Autores: Lantz, Frederic.
(Not controled OCR) Investment decision in the artisanal fisheries is a complex process involving a number of parameters (biological, economic) which are not known with certainty. Net investment is an effort capacity increase, so investment policy plays a major role in the fisheries management policy. Charles (1986) has pointed out the influence of the unit cost (including the cost of capital) on fisheries activity. In this study, capital budgeting methods are used to evaluate the investment projects. The first section recalls the cash flows calculation applied to artisanal enterprises. The consequences of the share system and public subsidies on the capital budgeting criteria are examined in section 2 and 3.

L'huître creuse Crassostrea gigas en Bretagne. Etude pilote en 1989 pour l'élaboration d'un réseau de données en biochimie, croissance, mortalité et pathologie de l'huître creuse sur huit sites conchylicoles bretons
Provedor de dados: 5
Autores: Le Bec, Claude.
Depuis son introduction en Bretagne, au début des années 70, peu d'études ont été consacrées à l'huître creuse Crassostrea gigas sur cette région, sauf lors de pollutions (Amoco Cadis) ou d'anomalies de croissance de la coquille. En l'absence de données récentes, des stations expérimentales "d'élevage" ont été mises en place sur 8 sites conchylicoles bretons. Un lot d'huîtres de "18 mois" est réparti en début d'année dans 96 poches, à raison de 6 poches par station et 2 stations par site. Des mesures de biométrie, de composition de la chair, d'lindex de qualité, de taux de survie, et de parasitisme sont réalisées après 7 mois d'élevage. Après étude des résultats variable par variable, une analyse descriptive par A.C.P. montre 6 groupes de sites ou stations...

Essai de cryoconservation des gamétophytes de l'algue alimentaire Undaria pinnatifida (Laminariale)
Provedor de dados: 5
Autores: Arbault, Suzanne; Renard, Philippe; Pérez, Rene; Kaas, Raymond.
Low temperature tolerance was determined for gametophytes of food alga Undaria pinnatifida according to various cryopreservation methods. Survival durations after storage in a medium containing 28% glycerol at −80 °C or in a 5-10% glycerol solution at −196 °C were only 9 and 4 days respectively. On the other hand, cooling at 5 °C/min. and storage at −15 °C for 15 minutes, without cryoprotective medium, did not reduce viability but this was highly decreased by storage for 15 minutes at −30 or −196 °C, with or without DMSO. The morphological cooling injuries were depigmentation and/or a contraction of the cells.

Autores: Littaye-mariette, Anne.
In the northern Bay of Biscay (France), catches of Atlantic sardine (Sardina pilchardus, Walbaum) fluctuated widely at a time-scale of a few days until the end of the fishery in 1970. These variations were not syndhronous between the adjacent Douarnenez, Audierne and Concarneau Bays in southwest Brittany, or between Belle-Ile, Quiberon and Le Croisic or the fishing harbours of Les Sables d'Olonne and Saint-Gilles-Croix-de-Vie further south. Wind speed effects on hydrology and circulation also varied between these areas. Significant relationships between wind speed from one specific component or an index composed with the tide range and the wind speed and catches per unit of effort or CPUE were obtained from regression analyses for all areas except Audierne...

After a literature overview of growth models applied to intensively cultured fishes, a new one is proposed for assistance in rearing operations, with following characteristics. A simple and integratable mathematic expression simulates growth while eliminating individual weight influence. It gives way to a specific growth general definition. Temperature action mode on growth speed is simulated by substraction of two exponential functions. An automatic calculation method of thermal parameters is proposed. The torpid action of low temperatures is considered. Feeding ration influences growth through simple rules which are explicitly taken in account by mean of a two parameters function. The other growth factors, more difficult to seize, are expressed through a...

After a description of the french fisheries management main features and institutionnal actors, we will try to analyse the rationalities at work in the French fisheries and their level of compatibility. It is generally assumed that a management scheme has to be chosen on the basis of its economical or biological efficency, which must be optimized. Actually, a constraint from outside seems to be the best incentive for management. The weigth of historical and cultural backgrounds often explains the diversity of answers provided by diverse actors facing the same constraint. In the French case, it also enlightens attitudes towards resource ownership and rights based fishing. Then, we will compare the advantages of the different management schemes implemented...

Élevage de la palourde japonaise Ruditapes philippinarum dans le bassin d'Arcachon. Bilan des dix dernières années et  perspectives de développement
Provedor de dados: 5
Autores: Robert, Rene; Deltreil, Jean-pierre.
Farming of the Japanese clam Ruditapes philippinarum took place for the first time in 1980 in the Arcachon basin. After an experimentation period of about ten years, a farming strategy, taking into consideration the distinctive features found in the bay, was able to emerge. For example, in order to fight against clam predators, crabs such as Carcinus maenas, and balistes such as Balistes capriscus, vertical protection coupled with prior ground gravelling, and laying of nets over the beds during the summer months, have become necessary. The best raising technique seems to rest on early spring planting of middle size spats (T5), after checking that no brown rings are visible. If clam growth seems to be better in oceanic zones, it looks similar in other areas...

Short term upper ocean oxygen changes at a fixed station in the southwestern Tropical Pacific (15 degree S, 173 degree E)
Provedor de dados: 5
Autores: Dandonneau, Y.
Oxygen concentrations were measured at discrete depths (0 to 250 m) at 20-day fixed station in an oligotrophic area (Proligo cruise of R/V Jean Charcot , 15 degree S, 173 degree E, September-October 1985). Measurements are available for both early morning and evening over a period of 14 days. Daily oxygen production is very variable, and does not permit a precise estimation of photosynthetic carbon fixation. Empirical orthogonal function analysis shows that the variability of the oxygen concentrations is null at the surface, increases evenly downwards, reaches a maximum at the depth of the nutricline and at the deep chlorophyll maximum, and decreases to null values at 187 m depth. Absence of a pronounced daily periodicity of the oxygen concentration is...

The Taumotou Archipelago, is considered as a potential area for the occurrence of cobalt rich ferromanganese crusts. A detailed seismic and seabeam survey carried out on the northern extension of the plateau has identified topographic highs along 2 main structural directions N 80E and N 150E. In this area, two sites have been surveyed with seabeam, 3.5 kc, and SAR side looking sonar; in addition, dredging and bottom photographs survey have been performed. For all the polymetallic crusts sampled dredged between 1,600 and 600 m, we confirm the enrichment in cobalt as a depth function; the increase in cobalt content is maximum at the outer part of the samples.

Observations dans les zones peu accessibles de l'environnement bathyal (biologie et geologie) grace a l'usage des soucoupes plongeantes
Provedor de dados: 5
Autores: Roux, M.
On the bathyal slope for continental margins, steep and rocky substrates punctuated with cliffs and collapsing zones are frequently found. As survey and sampling with the classical technics from the sea surface is practically impossible in such an environment, in situ exploration with a submersible allows significant advances in ecology, with implications in paleoenvironment reconstruction. Mixing of material from shallow-water and deep-sea origins into bathyal sedimentation suggests that the so-called "fossil assemblages of outer platform" were frequently misinterpreted. Dense populations of animals closely related to fossil groups which were only considered as relict of the Past ("living fossils") and previously interpreted as shallow-water inhabitants...

Autores: Monsaingeon, L.
The search for a panoramic, real-time, high frequency sonar has been a major goal for operating ranges where optical systems have established limitations. HYPSON 400 meets such requirements and provides a simultaneous and continuous beam-forming, no-scanning, wide opening system, using a hybrid beam-forming technique allowed by new component technologies. Up to seven images per second can be formed at a range of 100 meters, and more at shorter distances, as allowed by the speed of sound, thus providing the highest possible rate of information renewal required by operations at sea.

The mechanical behaviour of sediments is usually studied from laboratory core analyses which do not take into account the real state of in-situ stresses. Therefore, the aimed purpose is presently to determine the in-situ geotechnical properties which mainly depend on the relationship between fine-grained particles and intergranular fluids. At IFREMER, these achievements have been pursued in the framework of 2 scientific program: "Nodules and Sedimentary Processes and Instability on Slopes, for which surficial measurements were conducted on selected seafloor targets usually pre-defined from high resolution geophysical data." 2 kinds of instrumentation were developed in correlation to 2 different strategies of handling at sea. There is the instrumentation of...

The Teahitia-Mehetia hot spot region located in the southeastern extension of the Society Islands chain, near 18 degree S-148 degree W, consists of several active volcanoes. The distribution of recent volcanic activity correlates with seismic epicenters, and covers an area of more than 1,000 km super(2). Intermittent volcanic activity has given rise to large (&gt; 1,000 m high) and small (&lt; 500 m high) edifices composed of various types of flows. Several recent volcanic events have produced a suite of alkalic rocks ranging from ankaramites, through alkali basalts to trachy-phonolites.

Kystes modernes de Dinoflagellés en Baie de Vilaine-Bretagne Sud (France)
Provedor de dados: 5
Autores: Larrazabal, Me; Lassus, Patrick; Maggi, Pierre; Bardouil, Michele.
A preliminary study of modern marine dinoflagellate cysts has been performed in Vilaine Bay through winters 1986, 1987 and 1989. Direct observations of muddy sand samples and most probable number (MPN) method applied to cysts have evidenced a low win ter species diversity with Spiniferites spp. and Scrippsiella sp. cysts as predominant species. Change in relative importance of maximum species diversity area from ycar to year suggests a possible action of bottom currents. A study of dormant stages of toxie dinoflagellates, genus Alexandrium and Dinophysis, has corroborated the occurrence of A. minutum cysts (IO to 30 cysts.g-I sediment) at low amounts and absence of Dinophysis sp. resting stages. More generally, comparison of cysts in sediments with summer...

La chloration des effluents urbains avant rejet en mer
Provedor de dados: 5
Autores: Abarnou, Alain; Guillaud, Jean-francois; Miossec, Laurence; Batt, Agnes.
Chlorination of wastewater prior to effluent discharge into the sea is used as disinfecting treatment to preserve salubrity of the coastal marine environment wich is necessary for such activities as shellfish-farming and nautical sports. The disinfecting capacity of chlorine results from its oxydizing property which gives rise to various chemical reactions with constituents present in wastes. ln wastewaters, highly loaded with organic matter and ammonia, monochloramine is the main active chlorine species. Due to organic matter oxydation, thèse active chlorine species rapidly disappear by transformation into non toxic chloride. However, a very sm ail part of the initial chlorine dose can be found as stable and toxic chloroorganics. Monochloramine is also...

Intelligibilite de la parole en milieu subaquatique
Provedor de dados: 5
Autores: Casanova, M; Avon, M; Marchal, A; Gavarry, P.
Gas mixture and pressure modify the spectral characteristics of diver's speech. Additionally, constraints imposed on jaw movements by wearing a facial mask affect the speech production process. The auditory feedback loop is equally concerned. Furthermore, underwater adverse working conditions are characterised by noise from different sources. As a result, divers' speech is poorly intelligible and communications between divers and surface control need to be enhanced. To this end, "voice unscramblers" are being used. However, the technological state of commercially available equipment is dated and the quality of speech remains insufficient. To help with the design, testing and qualification (NORM) of new communication devices, a bilingual (French-English)...

Autores: Boutier, Bernard; Chiffoleau, Jean-francois; Gonzalez, Jean-louis; Noel, Joelle.
Raw and processed outflow from the Morlaix city sewage treatment plant were monitored every fourth hour for a 24 hours period, and monthly for eight months. The urban Hg, Cd, Cu, Zn and Pb outflow was shown to be much less than the river-borne flux. Sediments from the catchment area and estuary show that the influence of the town on the metal concentrations is limited to the harbour basin. The metal concentations are essentially controlled by granulometry.

La sedimentation quaternaire recente dans le detroit de Makassar (Indonesie)
Provedor de dados: 5
Autores: Gayet, J; Faugeres, J-c; Gonthier, E.
Corings have been obtained during the Misedor Cruise in the Strait of Makassar (Indonesia). Previous works showed that Recent Quaternary sediments originated from Kalimantan and Sulawesi. These deposits are associated either with settling processes or with paleogeographic events related to eustatic variations. At low sea level, gravity flow from Kalimantan supply deep-sea zones where deposits are arranged locally in stratodecreasing successions. During the rise of the sea level, inputs change both qualitatively and quantitatively. In addition to river-borne inputs (Mahakam), one can observe reworked sediments originating from the continental shelf in the course of its immersion. At high sea level (Holocene) inputs issued from Kalimantan contribute to the...

Autores: Chapelle, Annie.
The Vilaine bay (South Brittany) has been showing for many years eutrophication troubles (red tides, anoxia, toxic blooms...). Facing these biological and economical problems, scientific studies have been performed and the results are joined in an ecological box model of the bay. It simulates the primary production through nitrogen cycle, dissolved oxygen, and salinity, used to calibrate the advection-dispersion fluxes of the physical submodel. The model is running several years to bring out the seasonal characteristics of this site. A special attention is reported on the oxygen balance sheet. Simulations try to quantify the oxygen demand and to recognize the major cause of anoxia. These results are applied to reproduce the July 1982 anoxia, which caused...

Structure, age et origine des fosses arriere-arc des Nouvelles-Hebrides (Sud-Ouest Pacifique)
Provedor de dados: 5
Autores: Recy, J; Pelletier, B; Charvis, P; Gerard, M; Monjaret, M-c; Maillet, P.
The New Hebrides back-arc troughs are restricted to the southern and northern rear of the arc. Lack of trough in the central part is related to the compression induced by the collision of the d'Entrecasteaux ridge and the New Hebrides arc. The southern troughs are 50-60 km wide and are composed of one or two grabens striking N130-140 degree , while the northern troughs extend over 70 km wide and are composed of a succession of N-S trending grabens, horsts and half-grabens. Although the location and the main trend (N150 degree ) of the troughs indicate that they are largely guided by the subduction, the direction of extension (N40-45 degree ) is clearly oblique to the volcanic line and thus does not seem related to the subduction process.

The Okinawa Trough, lying to the East of China, is a back-arc basin formed by extension within continental lithosphere behind the Ryukyu trench-arc system. Middle to late Miocene uplift, associated with normal faulting of the initially adjacent Ryukyu non volcanic arc and the Taiwan-Sinzi folded belt, corresponds to the first rifting phase. The timing of rifting is supported by the presence of marine sediments of corresponding age drilled in the northern Okinawa Trough. The rifting occurred after a major early Miocene change in the motion of the Philippine plate with respect to Eurasia and ceased during the Pliocene.

From Normandy to Belgium bordary, the coastal fishery became during the ten last years a significant social and economic actor, which mostly lives by predominant exploitation of eastern Channel. Recently discovering a situation of resource overexploitation and a difficult cohabitation between "métiers", these coastal fleets are in the heart of various preoccupations of managment at regional, national and european levels. Since 1985, a coordinated programme including Boulogne and Ouistreham allowed to progress in the knowledge of complex fisheries through: improvement of statistics, characterisation of coastal fleets and their activity, assessment of the knowledge on the resources. This synthesis describes, for 1987-88, the quality of the regional landings...

Biomarker data associated with isotopic curve partial differential super(18)O served to establish a stratigraphic scale and thereby a chronology of fluctuations in the circulation and sedimentation of the Kalimantan continental rise throughout the last climatic cycle. During the glacial maximum, period of low sea-level sediments were deposited by turbidity currents originating from Kalimantan. During deglaciation, during rise of the sea-level and more particularly in the Holocene, material issued from Kalimantan either contributed to the building of the Mahakam delta or was dispersed over the shelf. Sulawesi inputs, less abundant and mineralogically different from Kalimantan material, were observed onto the Kalimantan rise. During this same period,...

Nitrogenous nutrient transfers in oyster ponds role of sediment in deferred primary production
Provedor de dados: 5
Autores: Sornin, Jean-marc; Collos, Yves; Delmas, Daniel; Feuillet-girard, Michèle; Gouleau, Daniel.
The oyster pond under study has a natural sediment bottom and water is changed only once or twice every month depending on tidal height. Between successive water renewals, the pond is a closed system, equivalent to a batch culture in which sinking and biodeposition of particulate matter are the only sources of organic matter to the bottom. Particulate organic matter enrichment of the sediment in winter is followed by intensive ammonification in summer with very limited nitrification. Seasonal nitrogen budgets involving particulate and dissolved phases show that in summer during batch mode period, ammonium enrichment from the sediment to the overlying water is an order of magnitude higher than the initial nutrient supply in the feed water. This allows a...

Evenements volcaniques cretaces dans le Pacifique Ouest et origine du bassin de Nauru (campagne Mesopac)
Provedor de dados: 5
Autores: Froger, V; Lancelot, Y.
The western part of the Pacific plate, where the oceanic crust is of Jurassic age, has undergone exceptional volcanic activity during the Cretaceous. It has produced numerous volcanoes (oceanic islands, guyots, seamounts) as well as very thick accumulation of volcanogenic material in the deep basins. The Mesopac cruise of the R/V Jean Charcot in the Nauru Basin obtained multichannel seismic profiles for the first time in these regions. This technique aimed at estimating the thickness of the cretaceous volcanics and locating the top of the underlying Jurassic crust. The results, when compared with those of DSDP drill holes, demonstrate that the abnormally shallow depth of the Nauru Basin results from an accumulation of flows and sills that constitute a...

Il est vrai que dans les pertuis charentais on ne rencontre pas de criée bien individualisée, hormis celle de La Rochelle, et les débarquements s'effectuent en de très nombreux points qu'il est difficile de cerner. La pêche n'intéresse qu'une flottille de petites unités travaillant pour la majorité d'entre-elles sur une base saisonnière. Elles doivent cohabiter avec un ensemble d'autres activites comme le tourisme et la conchyliculture qui tiennent un rôle non moins important. A cela s'ajioute les difficultés d'obtention de l'information sur les activités des flottilles. Pendant de nombreuses...

Application of spot data to a base-line ecological study of the mahakam delta mangroves (east kalimantan, indonesia)
Provedor de dados: 5
Autores: Dutrieux, Eric; Denis, Jacques; Populus, Jacques.
The objective of this study is to explain the spatial and temporal distribution of the vegetal communities of the Mahakam delta, chiefly on the basis of its physical and chemical characteristics. The delta is at present subjected to intense oil exploitation, and it is necessary to describe the situation on the site and its natural evolution in arder to be able to evaluate the damage that accidentai oil spillage could cause. The authors provide elements to define the sensitive zones whose protection should be a matter of priority. SPOT imagery was chosen as the tool allowing such an approach on a delta measuring 1 500 km2 SPOT satellite images of the Mahakam delta show that different plant communities succeed one another bath in time and in space. The...

Depuis la dernière journée RECHERCHE-ADMINISTRATIONPROFESSION consacrée aux « licences », trois ans se sont écoulés, au cours desquels sont apparus de nouveaux impératifs et de nouvelles contraintes tant économiques que politiques, parmi lesquelles de nombreux systèmes de régulation visant à limiter directement ou indirectement l'effort de pêche.  Certains systèmes de gestion des pêcheries, aujourd'hui assez largement éprouvés, avaient été abordés et analysés lors de la première rencontre de ce type, et la mise en commun des idées par les différents acteurs de l'interprofession avait permis, sinon de mieux accepter, à tout le moins, de mieux appréhender les grands principes qui avaient présidé aux prises de décision nationales.

Un modèle empirique du recrutement pour le stock de coquilles Saint Jacques, Pecten maximus (L.) en baie de Saint-Brieuc (Manche, France)
Provedor de dados: 5
Autores: Fifas, Spyros; Dao, Jean-claude; Boucher, Jean.
This paper proposes an empirical model for the recruitment of the scallop stock, Pecten maximus (L.), in Saint-Brieuc Bay (English Channel, France). This stock shows important fluctuations in recruitment. The use of traditional models for fish population dynamics based upon an equilibrium state were inadéquate. This model includes three independent variables: spawning biomass, effects of fishing effort on the unexploited year classes, and temperature. Correlations between these expressions of independent parameters and recruitment are systematically analysed. The choice of the final model relies on minimization of the total variance unexplained portion. Introduction of fishing pattern into the model is realized by testing fishing effort effects upon two...

Bonamia ostreae, an intrahemocytic protozoan parasite infecting the oyster Ostrea edulis, is responsible for an endemic disease affecting all intensive breeding areas of European countries. Epidemiological studies showed variable prevalences, 43% in Galicia (Spain), from 6% to 32% in France and 45% in the most important area of Ireland. The impact of oyster transfers, handlings, high densities have been implicated in the disease development but environmental stressors could be more involved than zootechnical methods. The effect of water temperature, salinity and tidal exposure were particulary examined to assess stress induced changes and determine physiological, biochemical and immunological state indices of oyster populations, which will contribute to...

Implantation sur le modèle courantologique Oko des lois de remise en suspension
Provedor de dados: 5
Autores: Raillard, Olivier.
Cette étude a pour but d'introduire dans le modèle de production globale du bassin de Marennes-Oléron une nouvelle source de variabilité des teneurs de la colonne d'eau en éléments particulaires par la prise en compte des échanges verticaux à l'interface eau-sédiment. Dans la précédente formulation du modèle les biodépots, alors la seule source d'alimentation du fond, sont instantanément remis en suspension. Toutefois la faible bathymétrie ainsi que des régimes de courants et de vents variables déterminent des variations importantes dans les concentrations du matériel particulaire (Bacher, 1989) susceptibles d'influer sur la production biologique primaire et secondaire (fig. 1). Ces échanges conditionnent en partie les fluctuations de quantité de lumière...

Autores: Gerla, Daniel.
Depuis son implantation en 1954, la mytiliculture en baie du Mont-saint-Michel a été frappée par de très graves crises. En collaboration avec l'ISTPM puis l'IFREMER, les professionnels ont su analyser les causes de ces chutes de production et mettre en place des mesures adaptées à la situation. La dernière en date étant une restructuration de l'implantation de l'ensemble des bouchots de la baie de 1985 à 1981. Cette volonté de gestion globale du bassin mytilicole du Vivier-sur-Mer semble aujourd'hui porter ses fruits au vu du niveau et de la qualité de sa production.

Nazca Plate fragmentation off Peru: The Mendana Fracture Zone
Provedor de dados: 5
Autores: Bourgeois, J; Huchon, P.
The Mendana Fracture Zone is a major intra-oceanic feature on the Nazca Plate off Peru. During the Seaperc cruise of R/V Jean charcot in 1986, Seabeam bathymetric data, single channel seismic records, geomagnetic and gravity measurements and heat flow data were obtained over this area. In this paper, we show that the Mendana Fracture Zone is actively opening perpendicular to its trend, resulting in the formation of new oceanic crust since about 3.5 Ma. This new rift is propagating westward along the fracture zone at a velocity of about 17 cm/yr with respect to the trench). The origin of the Mendana spreading centre would be the extensional stress acting parallel to the Peru Trench in this area.

Autores: Catherine, Martial; Blateau, Dominique; Mazurie, Joseph; Le Bec, Claude.
La recrudescence du ver Polydora dans les coquilles d'huîtres creuses observée dès l'été 1988 a pour principale conséquence le développement parfois très important de formations variqueuses et des chambres à vase à l'intérieur des huîtres, ce qui est très préjudiciable à leur qualité commerciale. Le bilan de l'infestation des coquilles d'huîtres par le ver Polydora sur le littoral normand et atlantique en mai et juin 1989 montre que les secteurs ostréicoles les plus touchés se situent à proximité de la Loire et de la Vilaine.

Managing nitrogen during the crop rotation to increase income and protect the environment
Provedor de dados: 18
Autores: Carter, David L.
National concern about nitrate contamination of  groundwater is raisin g many questions about the  use of nitrogen fertilizer to grow high-quality crops.  Some extremists are suggesting that commercial  inorganic nitrogen fertilization should not be permitted.  Such a limitation would seriously reduce crop  productivity and farming profitability. We hope that it does  not occur. However, the farming industry has become  somewhat careless in nitrogen management because  nitrogen fertilizer has been relatively cheap for the past  couple of decades. Commonly, "a little extra nitrogen" has  been applied to assure against a deficiency and less than  maximum yield. in recent years. sugar beet growers have  learned that such a practice can be costly because high...

Allocation of the Mantridae Leigh-Sharpe to the Cyclopoida (Crustacea: Copepoda) with notes on Nearchinotodelphys Ummerkutty
Provedor de dados: 16
Autores: Huys, Rony.
Mantra speciosa Leigh-Sharpe, 1934 (ex Poecilostomatoida), collected during the Siboga Expedition is redescribed on the basis of the holotype female. The 15-segmented antennule and the gnathostomous nature of the mouthparts exclude the Mantridae from the Poecilostomatoida and point to a relationship with the tunicate-infesting families Ascidicolidae, Notodelphyidae and Archinotodelphyidae (Cyclopoida). Nearchinotodelphys indicus Ummerkutty, 1960 (ex Archinotodelphyidae) is transferred to the Mantridae. It is suggested that the bivalveinhabiting mantrids have diverged from the ascidicolous lineage leading to the Notodelphyidae and Ascidicolidae.

Host utilization during ontogeny by two pycnogonid species (Tanystylum duospinum and Ammothea hilgendorfi) parasitic on the hydroid Eucopella everta (Coelenterata: Campanulariidae)
Provedor de dados: 16
Autores: Russel, David J.; Hedgpeth, Joel W.
The calyptoblast hydroids Aglaophenia struthionides (Murray, 1860), Eucopella (= Campanularia) everta (Clark, 1896), and Abietinaria spp. in the low intertidal zone at Mussel Point, Pacific Grove, Monterey Bay, California, often bear the adult pycnogonids Tanystylum duospinum Hilton, 1939 and Ammothea hilgendorfi (Böhm, 1879). Larval stages of these pycnogonids were found living and feeding on Eucopella everta. The larvae of Tanystylum duospinum are ectoparasitic. Those of Ammothea hilgendorfi are endoparasitic in the gastrovascular cavities of hydranths. Larvae of both species feed on the gut contents of Eucopella everta, often on the same hydroid colony.

Moult of wing and tail-feathers in the Ostrich, Struthio camelus
Provedor de dados: 16
Autores: Brom, Tim G.; Dekker, René W.R.J.
Structure and moult of wing and tail of a full-grown Ostrich, Struthio camelus, are described. In the wing, at least three feather generations could be recognized. The pattern of moult is more or less symmetrical in both wings and the sequence of feather replacement is not random. The tail consisted of 93 feathers of two different generations. Moult in the tail proceeds asymmetrically and seems to be fully irregular. The phylogenetic significance of these findings is discussed.

Resurrection of Hyla wavrini Parker (Amphibia: Anura: Hylidae), a gladiator frog from northern South America
Provedor de dados: 16
Autores: Hoogmoed, M.S.
During field work in Venezuela and Brazil a difference in call was noticed between specimens of large hylids of the Hyla boans-group. Based on this and on morphological differences, it was concluded that Hyla wavrini Parker, 1936, up till now considered a synonym of Hyla boans (Linnaeus, 1758), should be considered a valid species, of which Hyla miranda-ribeiri Melin, 1941 is a synonym. Durante trabajo de campo en Venezuela y el Brasil se nota una diferencia en el canto de especimenes de gran Hílidos del grupo Hyla boans.

In our paper on seaweeds of the Snellius-II expedition (Coppejans &amp; Prud’homme van Reine, 1989) we suggested that the new species Rhipilia nigrescens had been described in Phycologia. Due to regulations of that journal and corroborated by the short spell between acceptance and publication in Blumea, the Latin description can no longer be expected to be published as suggested. To validate the name of the new species a Latin description and a designation of the holotype is published here.

A new Benthopelagic species of Heterokrohnia (Chaetognatha) from the North Atlantic Ocean
Provedor de dados: 16
Autores: Casanova, Jean-Paul; Chidgey, Kathleen.
A new species of Heterokrohnia, H. mirabiloides, is described from the “Discovery” collections made in the North-East Atlantic. It differs from the two other species of the “mirabilis” group mainly in the cephalic armature, particularly the posterior teeth which are much less numerous and bent at rigth-angle. Although H. mirabiloides is benthopelagic as are all the Heterokrohnia species, most specimens have been caught using benthic sampling gear (31 out of 33 specimens). On the other hand H. mirabilis has been found in both benthic and pelagic samples (14 and 19 specimens, respectively). It appears that H. mirabiloides is the shallowest living species of the genus because the great majority of specimens (24) have been found at depths between 1300 and 1400...

Notes on a drawing of Indian elephants in red crayon by Petrus Camper (1786) in the archives of the Rijksmuseum van Natuurlijke Historie
Provedor de dados: 16
Autores: Bruggen, A.C. van; Pieters, F.F.J.M.
A drawing of two Indian elephants, signed "P. Camper f. 10 Sept. 1786", in red chalk or crayon, was found in the archives of the Rijksmuseum van Natuurlijke Historie in a manuscript by T.G. van Lidth de Jeude (1788-1863). Van Lidth de Jeude, professor at Utrecht university, obviously intended to use it as an illustration in his projected manual of the mammals in Dutch. The drawing is almost completely identical to an unsigned drawing in the Artis library, one of a series of three. The Leiden drawing is traced back to H. Schlegel, director of the Leiden museum 1858-1884, who most probably obtained the Van Lidth de Jeude papers upon his death. Van Lidth de Jeude is likely to have acquired the Camper drawing from G.J. van Klinkenberg (1768/69-1841), who in...

Laophontopsis Sars and the taxonomic concept of the Normanellinae (Copepoda: Harpacticoida): A revision
Provedor de dados: 16
Autores: Huys, Rony; Willems, Kris A.
The taxonomie concept of the subfamily Normanellinae Lang (Harpacticoida, Laophontidae) is revised. As a result a new family Laophontopsidae is proposed to accommodate Laophontopsis Sars and two new genera Aculeopsis and Telodocus. It is concluded that the presumed boreo-mediterranean distribution pattern displayed by the type species L. lamellifera (Claus) is merely the result of erroneous identifications. The population of northwest Europe is assigned to a new species L. borealis and another new species L. monardi is proposed for Monard’s (1928) material from Banyuls-sur-Mer. L. secundus Sewell is placed in the new genus Telodocus. Aculeopsis gen. nov. embraces only A. longisetosa spec. nov. and constitutes the most primitive genus of the family. The...

A field impression of the lichen and bryophyte zonation on Mount Kinabalu
Provedor de dados: 16
Autores: Sipman, H.J.M.; Tan, B.C.
Vegetation descriptions of Mount Kinabalu (4101 m), the highest mountain in tropical Asia between the Himalayas and New Guinea, have resulted in different, conflicting zonations. Some stress more on floristic affinities, others more on physiognomy. A lowland zone reaching to about 1000 m is usually distinguished. The next 2000 m comprising the mountain forests are treated in many different ways. A summit zone (above 3800 m) is recognized rather often (cf. Stapf, 1895; Gibbs, 1914; Meijer, 1963; Van Steenis, 1964; Menzel, 1988). In our opinion the most convincing is the zonation proposed by Van Steenis, who stressed the floristic composition. This comprises three zones: 1. the foothill zone below 1000 m; 2. the montane zone from 1000 to 2500 m; 3. the...

A taxonomic revision of the orchid genus Oberonia Lindley for India with 41 species is presented. Two new species, O. balakrishnanii and O. nayarii are established. Oberonia bisaccata and O. rangannaiana are considered conspecific with O. platycaulon and O. chandrasekharanii respectively. Oberonia acaulis and O. myriantha, which were treated as synonymous to each other by earlier workers, are now proved to be distinct species based on detailed study of the column. The species are grouped under six sections after modifying the classification proposed by Seidenfaden (1968) to suit the Indian plants. Dichotomous keys are provided for all taxa. The geographical distribution of each section within the country is discussed. All species are illustrated.

Autores: Renner, Susanne S.
Celestin Alfred Cogniaux, third of eight children of a customs officer, was bom on the 7th of April, 1841, in the village of Robechies on the border between Belgium and France. A promising pupil from the start, he got his higher education at the Ecole Normale in Nivelles where he received a teacher’s diploma at the age of 22. The next ten years Cogniaux taught at five different schools until 1872, when he was offered a position at the Jardin Botanique in Brussels due to the influence of his friend and mentor, the botanist-turned-politician Barthélemy Dumortier. Apparently the student Cogniaux, alone and without guidance, had taken an interest in the local flora, especially in the mosses and hepatics. In 1862, when he was 21, Cogniaux was one of the 92 men...

Discontinuous distribution of the tropical West Atlantic hydrocoral Millepora squarrosa
Provedor de dados: 16
Autores: Weerdt, Wallie H. de.
The hydrocoral Millepora squarrosa (Hydrozoa, Coelenterata) exhibits a limited, partly disjunct, distribution in the tropical western Atlantic. In the Caribbean the species is known from the Dominican Republic, Puerto Rico, Vieques, Culebra, the Lesser Antilles arc, and Barbados. It also occurs in Brazil. It is hypothesized that M. squarrosa is the descendant of an ancestor shared with the Indo-Pacific species M. platyphylla and that vicariance events prior to the Pliocene uplift of the Panamanian Isthmus have induced speciation of this ancestor into these species. The restricted Caribbean distribution of M. squarrosa is hypothesized to be the result of extinction of this species in certain parts of the Caribbean and its inability to re-intrude in these...

The newly defined order consists of the “old” families Axinellidae/Bubaridae and Desmoxyidae, a “new” family Dictyonellidae (containing Dictyonella, Acanthella, Liosina and Dactylella), and the new concept of the family Halichondriidae.

Taxonomy as a critical science
Provedor de dados: 16
Autores: Wattel, Jan.
The critical function is an important aspect of the science of taxonomy. Every classification is built upon a critical evaluation and emendation of a previously existing one. Ultimately, this reaches back to pre-scientific classifications which are, like scientific ones, hierarchically structured. The critical function is strongly developed in phylogenetic systematics in which some time-honoured taxa are no longer considered natural groups. Rejection of paraphyletic taxa has given rise to opposition against the phylogenetic methodology. It is suggested that paraphyletic taxa may be retained for administrative reference, but not for scientific evaluation of biogeography and evolutionary differentiation.

Phylogeny of the subfamilies of the family Braconidae (Hymenoptera: Ichneumonoidea)
Provedor de dados: 16
Autores: Quicke, D.L.J.; Achterberg, C. van.
A phylogenetic analysis of the subfamilies of the family Braconidae Nees, 1812 is presented. The analysis employing 96 phylogenetically informative characters was performed using the computerized parsimony programmes PAUP and Hennig86. The cladograms obtained show that the Braconidae can be divided into three major groups of subfamilies. These are a lineage comprising the mainly ectoparasitic cyclostomes and relatives, and two advanced endoparasitic groups, both apparently derived from somewhere near the endoparasitic cyclostome subfamily Rogadinae Foerster, 1862 sensu stricto. As a result of the phylogenetic analysis subfamily rank is given to the Exothecinae Foerster, 1862 (including the Hormiini Foerster, 1862), the Rhyssalinae Foerster, 1862 (including...

Provedor de dados: 16
Autores: Hovenkamp, P.H.; Viane, R.L.L.; Bremer, P.
Dryopteris expansa was recently discovered at two localities in the Netherlands (Havelterberg, prov. of Drenthe; Kuinderbos, prov. of Flevoland). Its diagnostic characters and taxonomic status are discussed. The taxon is morphologically very similar to D. dilatata and can only be identified by means of microscopical research (microglands c. 80 µm against c. 110 µm in D. dilatata; the diploid chromosome number whereas D. dilatata is a tetraploid). Nevertheless it is concluded that it must be regarded as a separate species. In the field D. expansa resembles Athyrium filix-femina in the light green colour and the soft texture of the lamina.

Dicrotrichura tricincta gen. et spec. nov.: A new tantulocaridan (Crustacea: Maxillopoda) from the Mediterranean deep waters off Corsica
Provedor de dados: 16
Autores: Huys, Rony.
The new genus and species, Dicrotrichura tricincta, is described from deep mud (1220 m) in the Ligurian Sea (western Mediterranean). It is the first tantulocaridan not found to be attached to a crustacean host but free living in the sediment. It is assigned to the Deoterthridae on the basis of the absence of a rostrum, the abdominal segmentation and the characteristic cephalic pore pattern. It can be distinguished from all known tantulocaridans in the presence of peculiar, bi-articulated caudal setae and the difference in thoracopodal setation between leg 2 and legs 3-5. Some new structures located on the attachment disc are described for the first time. D. tricincta is the second tantulocaridan to be recorded from the Mediterranean.

Frustrating facts about area cladistics and species individuality
Provedor de dados: 16
Autores: Gittenberger, E.
Area cladistics suffer from the fact that areas have various “histories”, as such dictated by different groups of taxa. Consequently, a generalized area cladogram has not or hardly any biological meaning. Conflicting area cladograms may be derived from even the same species, when their ranges in different geological periods are used. This is a consequence of the individuality of species.

Sexual strategies in the newts Triturus cristatus and Triturus marmoratus
Provedor de dados: 16
Autores: Zuiderwijk, Annie.
Courtship display characteristics are described and compared for the newts Triturus cristatus and T. marmoratus and patterns of male competitive behaviour are recognized. In interpreting the data, the operational sex ratio has to be taken into account, which was highly biased towards males in both species, more in T. marmoratus than in T. cristatus. When sexual active, males of cristatus had more encounters than males of marmoratus, whereas the latter spent more time residing mating places. The male’s display towards a female differed in time structure, variability and in behaviour characteristics. T. marmoratus display follows a fixed pattern; males succeeded better in restraining a female than males cristatus did. Courting males cristatus allowed other...

This book was composed after a manuscript left by W. Troll of his work Die Infloreszenzen II, part III, chapter 5, Fischer, Jena, 1969. Part I was published in 1964, part II in 1969. Weberling elaborated and updated this manuscript, describing examples of monotelic families, in the style of W. Troll. Together the three books – all wrapped in orange covers – represent a standard work consisting of more than 1700 pages and 1436 figures. The figures are combinations of photographs of living plants, explanatory drawings, and schemes. The drawings especially show good old handwork.

Arsenic accumulation in some higher fungi
Provedor de dados: 16
Autores: Stijve, T.; Vellinga, Else C.; Herrmann, A.
The high arsenic concentrations reported in literature for Laccaria amethystina were amply confirmed. In addition, it was demonstrated that Laccaria fraterna also accumulates the element, whereas in other species of Laccaria the phenomenon was far less outspoken. Few other basidiomycetes proved to have an affinity for the toxic element. The arsenic concentrations in the principal edible mushrooms of commerce were found to be very low, i.e. on the average 0.5 mg/kg on dry matter. Among the ascomycetes Sarcosphaera coronaria was recognized as an accumulating species. The arsenic content of four collections ranged from 360-2130 mg/kg with an average of 872 mg/kg on dry matter.

The zoogeography of the western Palaearctic Tipulidae (Diptera). X. The Tipulidae of the eastern Mediterranean islands
Provedor de dados: 16
Autores: Theowald, Br.; Oosterbroek, P.
A discussion is presented about the zoogeography of the Tipulidae known from the eastern Mediterranean islands; 54 nonendemic and 19 endemic species and subspecies are presently known from 25 islands. The non-endemic and endemic Tipulidae fauna of the islands close to Greece and Turkey is very similar to the fauna of the adjacent mainland. Older endemic as well as more widespread but relict species are found especially on the southern Aegean islands and on Cyprus. The Tipulidae fauna of the Kikládhes apparently is at large of quite recent, probably late Pleistocene origin.

Autores: Frisvad, Jens C.; Samson, Robert A.; Stolk, Amelia C.
A number of so far not correctly typified species of the genus Penicillium were re-examined. The profiles of secondary metabolites in old type strains and fresh isolates were compared. The type culture of P. implicatum Biourge was found to be identical with P. citrinum Thom. The first available name for P. implicatum sensu Raper &amp; Thom is P. hispanicum Ramírez &amp; al. Penicillium fellutanum Biourge and P. phaeojanthinellum Biourge are both considered to be synonyms of P. citrinum. Penicillium janthinellum Biourge sensu Raper &amp; Thom agrees with the iconotype of Spicaria simplicissima Oud., while P. simplicissimum (Oud.)

Aspects of the evolution and biogeography of stygobiontic Isopoda (Crustacea: Peracarida)
Provedor de dados: 16
Autores: Wägele, Johann-Wolfgang.
The evolution of the stygobiontic isopods is discussed correlating the phylogenetic system with biogeography. All stygobiontic isopods probably are derived from remote marine ancestors. The colonization of subterranean aquatic biotopes occurred in two ways: (1) via the coastal groundwater in the case of the Microparasellidae, Gnathostenetroididae, Stenetriidae, and in Cyathura (Stygocyathura), (2) in most families, however, via epigean freshwater ancestors. Ancient freshwater isopods that must already have existed before the Cretaceous and whose stygobiontic phylogenetic lines partly must have existed before the opening of the Atlantic are the Aselloidea, Calabozoida, Phreatoicidea, and probably also the Protojaniridae. In the course of Cretaceous and...

Biochemical systematics of the leaf mining moth family Nepticulidae (Lepidoptera). III. Allozyme variation patterns in the Ectoedemia subbimaculella group
Provedor de dados: 16
Autores: Menken, Steph B.J.
Gel electrophoretic techniques were used to analyse patterns of variation at 12 genetic loci within and among species of the Ectoedemia subbimaculella group from western Europe. Geographically separated conspecific populations were similar to one another genetically, with the exception of E. subbimaculella where the malate dehydrogenase locus exhibited clinal variation. Genetic differences among species often concerned loci that were monomorphic or slightly polymorphic within populations. Three of the species could not be diagnosed by their allozyme content; allele distribution patterns at some loci suggest that speciation took place recently and did not involve a genetic bottleneck. Phylogenetic trees constructed from allozyme data paralleled closely the...

Lovenula (Neolovenula) alluaudi (Guerne and Richard, 1890) in the Canary Islands (Copepoda: Calanoida: Paradiaptominae). Stygofauna of the Canary Islands, 19
Provedor de dados: 16
Autores: Bowman, Thomas E.
Lovenula (Neolovenula) alluaudi is widespread on Lanzarote, where it occurred at 22 of the 105 stations. On Fuerteventura it was found at only 2 of the 53 stations, both in the extreme northwest part of the island. It was also found in a reservoir on the south side of the small island of Alegranza. Samples collected at several hundred stations in the other Canary Islands failed to yield a single calanoid, supporting the belief that the eastern islands are fragments of the African continent that drifted to deeper waters. Males outnumbered females in about 2/3 of the samples, often heavily.

Het voorkomen van de Klimopwaterranonkel (Ranunculus hederaceus L.) in Nederland in relatie tot de hydrologie
Provedor de dados: 16
Autores: Diggelen, Riuiy van; Klooker, Julia.
In the Netherlands Ranunculus hederaceus L. is a relatively rare species, occurring in shallow streams. Measurement of water quality, however, showed that the species is quite tolerant with respect to mineral content and trophic status. In addition to this Ranunculus hederaceus is found in a wide variety of plant communities ranging from mesotraphent to very eutraphent ones. A map is presented showing the distribution of the species in relation to contour lines of the shallow ground water (fig. 3). This map indicates that the species is confined to steep gradients in contour lines adjacent to discharge areas. It is hypothesized that the rareness of this species nowadays in the Netherlands is caused not only by habitat destruction but most of all by changes...

Since the first edition (1949-1979) information has increased tremendously and therefore a second revised edition is now being prepared.

The genera Scotonycteris Matschie, 1894, Casinycteris Thomas, 1910, Pteropus Brisson, 1762 and Eidolon Rafinesque, 1815 are characterized. An effort is made to assess the possible relationship between the genera Scotonycteris and Casinycteris. Within Scotonycteris zenkeri Matschie, 1894 a number of geographically disjunct or probably disjunct and morphologically distinct population groups are recognized. The available material of Scotonycteris ophiodon Pohle, 1943 suggests that this species may also consist of a number of geographically disjunct and possibly morphologically distinguishable groups. Its distribution shadows that of S. zenkeri. The genus Casinycteris and the nature and function of its peculiarly shortened bony palate are discussed, in...

The Bulletin itself was felt to be an indispensable tool for local botanists and many complimentary words were spoken to its Editor (thanks!). Nevertheless, in a later evaluation at the Rijksherbarium, it was felt that the Bulletin contained information and a bibliography not always relevant to the plant taxonomy of the area. Hence this issue shows some changes. Some chapters have been merged and others deleted altogether. The one on New Records was not the success that we had expected as hardly any information was...

Tilia cordata and T. platyphyllos are both rare indigenous species. Also their hybrid, Tilia x vulgaris, can occur spontaneously. Among older trees (of girth &gt; 4.5 m) in villages or estates some specimens are found which may be original. About 50 of them have been located and are described in this paper, most of them belonging to Tilia x vulgaris. This hybrid was also cultivated since the 17th century, possibly starting from indigenous material. Propagation of originally indigenous specimens is important in order to develop more natural woodlands in the Netherlands. Older cultivars are of importance for restoration of historical sites.

Discovery of scientific correspondence of P.P.C. Hoek (1851—1914), including three unpublished letters by Charles Darwin
Provedor de dados: 16
Autores: Pieters, Florence F.J.M.; Winthagen, Diny.
Recently the scientific correspondence of the Dutch zoologist P.P.C. Hoek (1851—1914) turned up in the Artis Library. This collection contains three hitherto unpublished letters from Charles Darwin. It appears that Charles Darwin recommended Hoek to the favour of Sir Charles Wyville Thomson upon Hoek’s request for duplicates of Pycnogonida collected by the Challenger Expedition. This led to Hoek’s participation in the publication of the scientific results of the Challenger Expedition. Hoek’s report on the Pycnogonida was published in 1881 and those on the Cirripedia in 1883 (Systematic Part) and 1884 (Anatomical Part). In a letter to Hoek dated November 23, 1881 Charles Darwin praises Hoek’s contribution on the Pycnogonida as a magnificent piece of work...

Provedor de dados: 16
Autores: Pretus, J.L.
Odontozona addaia, a new species of stenopodid shrimp is described from a marine cave in the island of Minorca (Balearic Islands), being the first record of the genus for the western Mediterranean. One male and one ovigerous female were found during a systematic propspection of several Balearic caves during 1988. Sexual dimorphism is observed and described; the differences mainly concern a more developed third pereiopod in the male, and a distinct shape and armature of the pleonites and pleopods in both sexes. The distinction of this new taxon from the other known closely related species, O. minoica, is discussed.

Review
Provedor de dados: 16
Autores: Leenhouts, P.W.
Hawai’i is the most isolated major island group in the world, built up by and of volcanos and accordingly unstable but with a remarkable diversity of ecological niches. This has led to a flora on the one hand disharmonic (only three native orchids and one native genus of palms; no Gymnosperms nor primitive flowering plant families), on the other hand one of the worlds finest and most interesting ones. Though the island group is nearest to North America, most of the native flora is of Malesian affinity. In a sense, the flora is poor; one or a few colonist(s) often gave rise to a number of more or less closely related endemic species, some of which often relatively young polymorphic ones. The last complete treatment of the Hawaiian flora was Hillebrand’s...

Autores: Deets, Gregory B.; Dojiri, Masahiro.
A new species of siphonostomatoid copepod, Dissonus pastinum, is described from the horn shark, Heterodontus japonicus (Dumeril), from Awa, Japan. The new species differs from all congeners except D. ruvetti Nunes-Ruivo &amp; Fourmanoir, 1956 and D. nudiventris Kabata, 1965 by the presence of the sternal furca and absence of spines on the genital complex. However, the new species can be distinguished from D. ruvetti by having a 1-segmented abdomen and from D. nudiventris by the absence of a large accessory spine on the second antennal claw.

A characteristic species of small ephemeric waters in the Dutch riverclay area is Tolypella prolifera. The distribution of this species is most likely restricted to Europe, with an optimal occurrence in the Netherlands. Due to the pollution of the river Rhine many localities of this species have disappeared. Data on distribution, taxonomy, ecology and phytosociology are presented and possibilities for the protection of this rare species in the Netherlands are discussed.

Autores: Bosscha Erdbrink, D.P.; Bree, P.J.H. van.
Six cranial and two postcranial fossil and subfossil odobenid remains that have come to our notice since our 1986 paper on the same subject are described and discussed. One of these can, with some confidence, be identified as Odobenus antverpiensis (Rutten, 1907). The others either belong to the recent species, Odobenus rosmarus (Linnaeus, 1758), or should simply be identified as Odobenus species. Some remarks are made on the morphological differences between antverpiensis (perhaps identical with huxleyi) and rosmarus.

Genetic differentiation and estimated levels of gene flow in members of the Gammarus pulex-group (Crustacea, Amphipoda) in western Europe
Provedor de dados: 16
Autores: Scheepmaker, Maarten.
Genetic differentiation of morphologically variable members of the G. pulex-group in northwestern Europe was investigated by electrophoresis at 20 enzyme loci. Five recently described related forms were examined with reference to the “classical” species G. pulex, G. wautieri and G. fossarum. G. pulex and G. wautieri were shown to be genetically homogeneous and clearly distinct species. In the other species, morphologically similar forms were shown to be genetically distant, and inter-areal intraspecific genetic differentiation may warrant recognition of subspecies or sibling species. In some cases, levels of reproductive isolation of the forms involved could be assessed by cross-breeding experiments. To estimate dispersal capabilities, gene flow levels...

Precopulatory mate guarding in copepods
Provedor de dados: 16
Autores: Boxshall, Geoffrey A.
In many copepod species adult males clasp females for an extended period before transferring spermatophores. Clasping juvenile females (first to fifth copepodid inclusive) is interpreted as mate guarding and is shown to be widespread among podoplean copepods. It is distinct from copulation, which takes place only between adults and is often distinguishable from mate guarding by a difference in clasping posture.

This book is sequel to Volume 14A, Tropical Forest Ecosystems, structure and function. Whereas the first volume deals with system ecological aspects such as community organization and processes, the present volume concentrates on biogeographical aspects such as species composition, diversity, and geographical variation. Recent ecological research in the tropical rain forest has greatly extended our understanding of biogeographical patterns on variation in the various groups of organisms and has revealed many of the ecological and evolutionary forces that led to the present patterns of variation. Many important systems of co-evolution between the tropical rain forest ecosystems have also come to light, and the loss of species and related damage is better...

Genetic differentiation, origin and dispersal of Gammarus gauthieri from the Iberian peninsula and North Africa (Crustacea, Amphipoda)
Provedor de dados: 16
Autores: Scheepmaker, Maarten.
Genetic differentiation among population samples of G. gauthieri on both sides of the Strait of Gibraltar was investigated by enzyme electrophoresis at 20 enzyme loci with reference to G. gauthieri and G. ibericus from different areas in the Iberian peninsula. Levels of divergence resolved suggest that G. gauthieri reached North Africa from the Iberian peninsula, and not vice versa. With reference to geological evidence, this was likely to occur during the Messinian (6—5 My ago). As the opening of the Strait of Gibraltar represents a well dated geological event, an attempt has been made to calibrate the molecular clock for the G. pulex-group. Indirect estimations of gene flow levels were shown to be extremely low. Probably as a consequence of frequently...

Nephelieae pollen (Sapindaceae): Form, function, and evolution
Provedor de dados: 16
Autores: Ham, R.W.J.M. van der.
Two main types may be distinguished within Alectryon pollen: the colporate type and the parasyncolporate type. These types are not clear-cut, but merge into each other through a complete series of intermediate forms. The colporate type has usually a colporate apertural system, a high P/E value (av. 0.97), a low A/E value (0.32), and striate to striate-rugulate ornamentation. The parasyncolporate type shows usually a parasyncolporate apertural system, a low P/E value (av. 0.76), a high A/E value (av. 0.46), and striate-rugulate to rugulate ornamentation. In addition, there is some difference in endoaperture and nexine morphology, and the relative length of the peripheral columellae of a mesocolpium. An endoaperture in a colporate grain often shows acute or...

New distribution data for Podocnemis erythrocephala (Spix) with remarks on some other turtle taxa (Reptilia: Chelonia: Pelomedusidae)
Provedor de dados: 16
Autores: Hoogmoed, M.S.; Avila-Pires, T.C.S. de.
During fieldwork in the Lago de Faro, the lower reaches of the Rio Nhamundá, on the border of the Brazilian states of Pará and Amazonas, several species of pelomedusid turtles were observed. Podocnemis erythrocephala and P. unifilis occur in the area and breed there; P. expansa seems to be absent or at least very rare, though it does occur nearby in the Rio Trombetas. A single specimen of Peltocephalus dumeriliana was collected opposite the Ilha dos Maicós in a small igarapé emptying in the Rio Trombetas. It is concluded that the distribution area of Podocnemis erythrocephala is more extensive than recently thought.

Tuluweckelia cernua, a new genus and species of stygobiont amphipod is described from six anchialine caves near the northeastern coast of the state of Quintana Roo on the Yucatan Peninsula in Mexico. The new genus is closely allied morphologically with Mayaweckelia Holsinger, which is also recorded from caves on the Yucatan Peninsula. Both taxa have probably evolved from marine ancestors since the late Tertiary.

Charles Chilton: the Phreatoicoidea and other interests of a phreatic pioneer from down under
Provedor de dados: 16
Autores: Hurley, D.E.
Besides his widespread activities in zoology and university development, Charles Chilton (1860—1929) was a pioneer in phreatic research who opened up the possibilities of the new science in the Southern Hemisphere. He described phreatic and subterranean species of Isopoda and Amphipoda from New Zealand, Australia and elsewhere and discussed the significance of their morphology and habitat. His finds included the first species of the widespread endemic Southern Hemisphere group, the Phreatoicoidea, and he pointed to Gondwanaland connections in this and other groups which he accepted and interpreted in the context of his time.

The Hamameli(i)dae comprise, according to the new classification by Thorne, about one quarter of the genera to one third of the families of the Dicotyledonae. The symposium held at the University of Reading, U.K, 22-25 March 1988, highlighted some of the many questions concerning phylogeny and evolution in this group as a contribution to the insight in the main lines of dicotyledonous evolution. The symposium report contains a wealth of information on a wide variety of topics. The phylogenetic position of the Hamamelidae in a wider or narrower sense, or parts thereof, is subject of a number of papers. F. EHRENDORFER reviews the existing diverging interpretations and concludes that the Hamamelidae can be regarded as ancient and partly relictual survivors...

Growing knowledge and understanding of dichromatism and sex reversal in Labridae
Provedor de dados: 16
Autores: Roede, Machteld J.
A brief survey is given of current literature in comparison with former studies. Since the 18th century phenotypic diversity of Labridae is a matter of argument. At first in dribs and drabs, yet last decades at a rapid rate, dichromatic adult morphs are synonymized. There are few monochromatic species. Wrasses are protogynous hermaphrodites. Most species are described as monandric, but a minority (of slightly or extremely dichromatic) species is diandric, with both primary and secondary males. Terminal males reproduce with single females, but initial phase males spawn in aggregations. Some species are haremic, and large males are permanently or temporarily territorial. Last decades insight in the various social factors has greatly increased, resulting in...

日高山脈ペテガリ岳西尾根における小哺乳類の垂直分布
Provedor de dados: 19
Autores: 柳川, 久; 伊藤, 晴康; Yanagawa, Hisashi; Itoh, Haruyasu.
北海道日高山脈のペテガリ岳において1981年7月と8月に小哺乳類の垂直分布を調べた。食虫目1種,翼手目2種,齧歯目5種および兎目1種の生息が確認された。標高500-1736m間の捕殺わなによる採集で,オオアシトガリネズミ,ヒメネズミ,エゾアカネズミ,ミヤマムクゲネズミ,エゾヤチネズミ,ミカドネズミの2目6種の地上性小哺乳類が捕獲された。ヒメネズミは森林において優占し,特に低標高の下部落葉広葉樹林から針葉樹林に多かった。他方,エゾアカネズミはこれらの森林では殆ど見られず,その理由としてヒメネズミとの種間関係が考えられる。コウモリ類はキクガシラコウモリとホオヒゲコウモリの2科2種が標高470mの地点でかすみ網によって捕獲された。エゾナキウサギはペテガリ岳Bカール(標高1340m)において鳴き声によって確認された。  Vertical distribution of small mammls was surveyed on Mt. Petegari, the Hidaka Mountains, Hokkaido in July and August 1981. One species of Insectivora, two of Chiroptera, five of Rodentia and one of Lagomorpha were recorded. Snap-trapping was done at the altitudes of 500 to 1736 m . Six species of small terrestrial mammals belonging to two orders were captured, i.e. Sorex unguiculatus, Apodemus...

Global climate change and the vulnerability of the Nigerian coastal zone to accelerated sea level rise: Impacts and responds.
Provedor de dados: 20
Autores: Ibe, A.C.
In the recent past, climatic changes and variations have occurred in Nigeria with resulting adverse socio-economic impact. From these experiences, it is inferred that the expected change in global climate will have far reaching disastrous consequences for Nigeria if appropriate anticipatory technical and policy Measure are not taken. More recent results from various models based on an eventual warming from a doubling of greenhouse gases of between 1.5 and 5oC by the end of the 21st century predict an acceleration of the eustatic rise in sea level from 1.2-1.5mm/yr. over the last hundred year s to 4 – 6mm/yr. although previous estimates were much higher [e.g.56–3.68m by the end of the 21 century] on the low lying Coastal zone of Nigeria, which is rich in...

Estudio de la edad y crecimiento del recurso merluza común (Merluccius hubbsi) durante el período 1968-1970; determinación de las fluctuaciones del recurso
Provedor de dados: 20
Autores: Villarino, M.F.
La merluza común (Merluccius hubbsi) es uno de los más importantes recursos pesqueros del Mar Argentino. Constituye aproximadamente el 68 por ciento de las capturas desembarcadas, según lo indicado por las estadísticas oficiales (Boletín Oficial, Subsecretaría de Pesca, 1988). Su explotación ha mantenido una tendencia creciente a partir de 1974, como consecuencia del incremento de las capturas de Argentina y el plan de desarrollo pesquero implementado por Uruguay. Las capturas de 1978 y 1979 superaron ampliamente el valor del rendimiento máximo sostenible, estimado en 344.000 toneladas (Verazay y Otero, 1986), y se mantienen próximas al mismo a partir del último año mencionado.Como resultado de esta explotación el recurso pesquero se redujo aproximadamente...

Autores: Chavance, P.
Résumé : En 1988, 63 chalutiers pélagiques (55-102m, 2000-3880cv) ont opéré dans la ZEE mauritanienne ainsi qu’un senneur de 55m et 3600 cv. La Mauritanie, et quatre nationalités étrangères sont représentées : le Ghana, la République démocratique allemande, la Roumanie et l’URSS. La capture totale etteint 400800 tonnes dont 69,3% est pêchée par les soviétiques, 29,9% par les roumains, 0,6% par les allemands de l’est et 0,2% par la flottille nationale. Les espèces principales sont les chinchards qui prédominent dans les captures avec 53,2%, la sardine (13,2%), les sardinelles (10,7%), le maquereau (7,5%) et le sabre (6,4%). L’activité des flottilles est parue, comme les années précédentes, très marquée par les saisons hydrologiques. #

Se registra un total de 263 especies de moluscos (201 encontradas vivas) colectadas entre 1982 y 1989 en siete localidades arrecifales de la región de Santa-Marta, Colombia. Los moluscos fueron ordenados de acuerdo a las zonas de arrecife en que fueron encontradas, a sus hábitos alimentarios y a su modo de vida. El dendrograma resultante del análisis de similaridad faunística entre las zonas muestra que existen tres tipos básicos de comunidades en el arrecife (asentadas respectivamente en zonas someras, zona de declive arrecifal y zona con coral muerto y arena), más una comunidad pobre en especies y restringida a la zona dominada por el coral Agaricia tenuifo/ia. Existen algunas diferencias entre las zonas arrecifales en cuanto a la distribución porcentual...

Autores: Cornejo Rodríguez, M.P.; Lucero, M.
Parámetros físicos tales como: temperatura, salinidad y velocidad geostrófica han sido estudiados en conjunto para realizar un análisis de la estructura de la Corriente de Cromwell (Subcorriente Ecuatorial), entre 92° 30' W y 84° 30' W y entre las latitudes de 1°N y 4°S, para épocas normales y anómalas como la ocurrida durante el evento de El Niño 82-83. Los valores de velocidad fueron obtenidos usando el método de Montgomery (método indirecto), el cual permite calcular velocidades geostróficas en latitudes bajas. Los resultados conseguidos con este método muestran la presencia de la Subcorriente Ecuatorial, concluyéndose que la metodología aplicada es confiable. Sin embargo, cuando se trata de épocas anómalas como en el caso de "El Niño", los altos...

Seychelles tuna bulletin : fourth quarter 1990
Provedor de dados: 20
The number of purse seiners active in the western Indian Ocean average 41 during the fourth quarter compared to 49 vessels during the same period last year.  Fishing activity was high during the first half of the year with a record of 54 vessels present in February and March. The overall fishing results for the year were not as good as those previously recorded in the last three years.  Catch rates averaged 16MT/day compared to 18 MT/day in 1989 and 22 MT/day in 1988, attaining a similar level to results of 1986.  This was due to poor fishing conditions during January to May causing several vessels to leave the Indian Ocean in June.  However this situation changed as catch rates improved during the second half of the year, with exceptionally high yellow...

Seychelles tuna bulletin : first quarter 1990
Provedor de dados: 20
The number of purse seiners active in the Western Indian Ocean peaked to an all times high for the first quarter of 1990 ranging from 50 in January to 53 in March.  This represents an increase over the same period last year when an average of 48 vessels was in operation. Fishing results were rather poor throughout the first quarter of this year. Catch rates increased only slightly from a low of 8.18 mt/day in December 1989 to 16.7 mt/day in March 1990.  The proportion of yellow fin in the catch however increased considerably from 39% in December to 67% in February 1990, with a corresponding decrease in the proportion of skipjack in the catch.  This is usual for this time of the years when yellow fin is the predominant species. The fishing pattern was...

An upsurge in the prevalence of rusty-yellow discoloration of the skin of the two tilapia species, being cultured at the African Regional Aquaculture Centre (ARAC), gave a basis for an urgent clinical and epizootiological studies of the condition.  The studies were therefore carried out along with the performance of some catfishes in polyculture with Oreochromis niloticus, under the integrated poultry cum fish farming system. It was observed that this condition affects the tilapia species only, and the antemortem, and postmortem examination revealed that the discolouration is restricted to the surface of the cutaneous tissue; affecting the underside of the exposed part of the scales, the fins and the skin flap covering the scale pockets, mostly in adult...

The number of purse seiners active in the Western Indian Ocean increased from a low of 41 at the end of the last quarter to 45 vessels in September. Fishing results improved slightly with daily catch rates for the third quarter averaging 22 MT, increasing from 17.7 MT/day in August to 31.5 MT/day in September.  These results are considerably better than those for the same period last year when it averaged 16 MT/day. The fishing pattern for the third quarter showed that fishing effort was concentrated between 5 degrees north and 5 degrees south of the Equator in the vicinity of the Northern sector of the Seychelles EEZ. Fifty five percent of the third quarter catch was made up by skipjack tuna compared to 58% for the second quarter.  This is partly due to...

The fishery is presently comprised of an industrial trawler component and an artisanal component. During 1989 there were sixteen trawlers engaged, two belonging to the parastatal Tanzania Fisheries Corporation (TAFICO) and the rest being foreign-owned. The landings from these vessels included 974 tonnes (whole weight) of shrimp and 1,069 tonnes of fish by-catch. Almost all the shrimp were exported. The wholesale (fob) value of the shrimp was probably in the order of US$ 5.5 million. On the basis of data collected during a socio-economic study undertaken immediately prior to the Workshop, the estimated landings by the about 859 artisanal fishing units in 1989 was 1,212 tonnes of shrimp suitable for export, along with over 3,000 tonnes of fish.

Résumé : Au mois de mars 1989, 770 embarcations employant 3537 pêcheurs ont été recensées, tandis qu’au mois d’août de la même année seules 540 embarcations ont été recensées. Ces dernières emploient 2236 pêcheurs, soit une diminution du parc d’embarcation de 30% et de l’effectif des pêcheurs de 38%. Les « Imraguen » commencent à diversifier leur technique de pêche en utilisant de nouveaux engins. La pêche artisanale intéresse de plus en plus les mauritaniens qui n’ont pas une tradition de pêche. En effet, des pêcheurs originaires des régions de l’intérieur de la Mauritanie représentaient 10% de l’effectif en février 1989 et 34% en août 1989. #

Velocidades superficiales de las aguas fueron medidas en la Bahía chile en la Isla Greenwich, como parte de la Segunda Expedición Ecuatoriana a la Antártida, durante el verano del hemisferio sur, en 1990. Masas de hielo a la deriva desprendidas desde la costa fueron usadas como trazadores lagrangianos. Son comparadas corrientes superficiales y observaciones de vientos. La circulación superficial es determinada por los vientos cuando la velocidad de estos últimos exceden los 6 m/s.

Coral bank obstructions to trawling in the middle to outer continental shelf east and west of Lagos.
Provedor de dados: 20
Autores: Awosika, L.F.
The continental shelf east and west of Lagos [long.2o.04.00E to long.4o 00’.00”E] is narrow shelf ranging in width between 25 to 30 kilometers. Echograms from several NIOMR’s cruises reveal the presence of some isolated and in some cases continuous bands of dead Holocene coral banks, within the middle to outer continental shelf [40-120m depth]. The most prominent of these structures are ones occurring between 75-100m of water and running almost parallel to the coastline. The dead coral structures are non-reef forms. They are found either as continuous Bands of rough bottom with width ranging between, 100 to 3,500m or in isolated pinnacled shapes. The pinnacled forms reach heights of over 7 meters in some cases. These coral structures pose obstructions to...

Introduction of Fish Aggregating Devices in the Southwest Indian Ocean (A Case Study)
Provedor de dados: 20
Autores: Venkatasami, A.
During the past decades, several countries of the Southwest Indian Ocean region have attempted setting Fish Aggregating Devices (FADs) with varying success. Initially, FADs were rapidly lost without being able to produce any results. The gradual improvement in design through the work carried out mainly by SWIOP1 in the region, lead to the development of long lived FADs in Mauritius. The transfer of that technology to other islands such as Reunion, Madagascar, Comores and Rodrigues (Mauritius) gave a new impulse to the activity.

Seychelles tuna bulletin : second quarter 1990
Provedor de dados: 20
The number of purse seiners active in the Western Indian Ocean decreased sharply from an all high of 54 in the first quarter of 1990 to 44 by June.  This, however, still represents an increase in the number of active vessels from the same period last year when there were 38 vessels in operation. Fishing results continued to be poor throughout the second quarter, showing only a slight improvement in June. Catch rates were an all time low since 1985 averaging 10.3 MT/day for the quarter compared to 13.5 MT/day for the same period in 1989.  The proportion of yellow fin in the catch decreased to 25% in April, 23% in May and then recovered remarkably in June (80%).  These results however are not entirely unusual for this time of the year.

Altas temperaturas estacionales del agua como condición disturbadora de las macroalgas del Parque Nacional Tairona, Caribe colombiano: una hipotesis
Provedor de dados: 20
Autores: Bula-Meyer, G.
Con base en observaciones de campo y en mediciones de los factores temperatura, salinidad, nutrientes, transparencia y movimiento del agua, se analizó cada uno de éstos con el fin de conocer el factor más importante en el control del crecimiento y productividad de las macroalgas del Parque Nacional Tairona en la costa Caribe de Colombia. Se hipotetiza que el factor clave que regula estos aspectos fisiológicos de las macroalgas del Parquees la temperatura. Su ascenso por encima de los 26°C, como resultado de la declinación del afloramiento y de otros fenómenos oceanográficos-meteorológicos, produce la disturbancia (remoción de biomasa) de las macroalgas que se observa anualmente en la estación húmeda mayor.

Résumé : Les 6 campagnes de chalutage réalisées en 1987 et 1988 ont permis d’évaluer les indices d’abondance des diverses ressources démersales, essentiellement poisson et céphalopodes, par strate, zone et, pour l’ensemble du plateau continental. Des estimations de biomasse apparente (77'000 tonnes en 1988) et de potentiel maximum exploitable (59'200 t. en 1988) ont aussi été avancées. La comparaison de ces résultats avec ceux des années 1982-1984 a fait ressortir une nette tendance à l’amélioration générale depuis 1987. Si la situation de la zone nord (Cap Blanc) demeure encore préoccupante par rapport à celle du sud, l’abondance globale des ressources du plateau a retrouvé un niveau peu inférieur à celui des années 1982-1983.

The effect of oil exploration, production and other oil related industrial activities on the estuarine environment of the Niger Delta has resulted in increasing need of baseline information to be used as background levels against which pollution effects could be detected and monitored.  A one-year (December, 1986 - December, 1987) baseline survey of the benthic foraminiferal fauna of the Bonny estuary showed that arenaceous forminifera strongly dominated the total and living assemblages.  The subordinate calcareous groups were mostly found in the lower reaches of the estuary.  The foraminiferal fauna was represented by thirty-three species, twenty-three of which were arenaceous, nine calcareous and one porcellaneous. Twenty nine of the thirty-three species...

Seychelles schooner fishery: an analysis of data collected during the period January 1985 to July 1990
Provedor de dados: 20
Autores: Mees, C. C.
Schooners are the largest category of vessel participating in the local fishery. They are fully decked fishing boats equipped with inboard engines and fish with handlines or electric fishing reels. They account for about 15% of the total artisanal catch, but commercially valuable demersal species predominate. Their economic importance is thus greater than the catch volumes would indicate. Furthermore, they have the greatest range and are able to undertake longer fishing trips than other local vessels. They, or a similar class of vessel, are thus considered vitally important for the future development of the local fishery, where the potential for expansion from demersal species is considered to be offshore on the more distant banks and island groups. The...

The effect of season on the controlled propagation of C. gariepinus was investigated.  The hypophysation of C. gariepinus using the pituitary extract from the sacrificed C. gariepinus was carried out from July, 1987 to June 1988.  The female broodstock weight ranged from 0.50kg while the male weight, from 0.5kg to 0.6kg.  The condition factor of the female broodfish was more or less uniform (1.3 to 1.7). The results showed that there was peak production of eggs by the female during the rainy season.  Eggs production for rainy season ranged from 28,000 eggs/kg body weight in June to 37,600 eggs/kg body weight in August.  The percentage hatching of the fertilized eggs was also higher in the rainy season than the dry season.  The highest hatching of the...

Grâce aux flux migratoires on note une présence de pêcheurs étrangers qui contribuent au développement de ce secteur en introduisant des nouvelles techniques (engins,  embarcations) et organisations. Ces pêcheurs (mauritaniens et étrangers), en majorité Wolofs, composent l’essentiel des effectifs présents sur la façade maritime mauritanienne. Avec les Imraguen, ils travaillent en complémentarité car n’exploitant pas les mêmes espèces de poisson. #

Provedor de dados: 20
Autores: de Montaudouin, X.; Hallier, J.-P.; Hassani, S.
The tuna purse seine fishery based in Seychelles is analysed using data collected by observers on board French, Spanish, Japanese and Soviet vessels. From 1986 to 1989, diffferent types of data were recorded such as meteorolical and oceanographic parameters, aspects and sizes of schools sighted, seiner activities, fishing characteristics (catch, yield, duration of fishing sets). Reliability of observers data with respect to catches is assessed by comparison with log data from French purse seiners.

Autores: Dublin-Green, C.O.
This study is based on eight research cruises carried out on the bonny river system from December 1986-september 1988.  Variations in some physico-chemical parameters of water [Transparency, temperature, pH, DO, salinity, conductivity, PO4, NH4 SiO2 and alkalinity] observed at 10 stations located in the main channel of the river are presented.  Results showed that salinity, conductivity, pH, DO, and alkalinity exhibited spatial and temporal variations. In general, the upper estuary was slightly acidic while the middle and lower estuary were alkaline .A slight decrease in water temperature with depth was observed in most of the stations.  The amplitude of variation in surface and bottom water temperature was generally between 0.5-2oC.  Significant salinity...

Caracterización ecológica de la salina artificial Pozos colorados, Caribe colombiano
Provedor de dados: 20
Autores: Mancera-P., J.E.
Un estudio ecológico de la salina marina Pozos Colorados se llevó a cabo entre enero y agosto de 1987. Si bien las dos estaciones de muestreo presentaron amplias diferencias entre si; en general la dinámica del ecosistema dependió aparentemente de la salinidad, la cual varió entre 75 y 341 °/oo; su incremento y la disminución del nivel de agua, al parecer generaron aumento de la temperatura y disminución del oxígeno disuelto, con rangos de 26,3 y 41 °C para la primera y O y 5,4 mg/l para el segundo. Aunque en promedio el pH fue neutro (7,5), este sistema reductor, caracterizado además por abundante materia orgánica, generó en ocasiones una ligera acidez (6,7). La producción primaria neta fue negativa en la mayoría de los casos, como resultado de una...

La langouste rose Palinurus mauritanicus de Mauritanie : Biologie, pêche et état du stock
Provedor de dados: 20
Autores: Kojemiakine, A.; Diop, M.
Résumé : La biologie de la langouste rose des côtes mauritaniennes est aujourd’hui bien connue. Nous avons cependant rappelé les traits marquants. Sur le plan de la pêche, de 1963 à 1988, le stock de la langouste rose a connu trois phases d’exploitation. Après une phase de surexploitation entre 1963 et 1970-1971, le stock de langouste rose de Mauritanie a pu se reconstituer grâce à une réduction importante du nombre de langoustiers. Ceci c’est traduit à partir de 1971 par une augmentation sensible des captures et aussi de la PUE. Mais le dédoublement du nombre de ces derniers en 1987 et 1988 a fait chuter les P.U.E de 50% ce qui est un signe d’effondrement du stock à nouveau.

A study of the performance of Clarias gariepinus (African Mudfish) in a polyculture with Oreochromis niloticus (Tilapia), integrated with broiler chicken production was carried at the African Regional Aquaculture Centre, Nigeria.  Three experimrntal treatments were utilized.  Treatment I was a polyculture of C. gariepinus and O. niloticus integrated with broiler chicken production, with application of supplemental feed to fish.  Treatment II was a repeat of treatment 1, except that no supplemental feed was applied to fish, while treatment III was a polyculture of the two fish species per se with application of supplemental feed to fish.  Results showed that the final individual weight, individual weight gain and recovery rate were best for C. gariepinus,...

Autores: Huys, R.
&lt;i&gt;Mantra speciosa&lt;/i&gt; Leigh-Sharpe, 1934 (ex Poecilostomatoida) collected during the Siboga Expedition is redescribed on the basis of the holotype female. The 15-segmented antennule and the gnathostomous nature of the mouthparts exclude the Mantridae from the Poecilostomatoida and point to a relationship with the tunicate-infesting families Ascidicolidae, Notodelphyidae and Archinotodelphyidae (Cyclopoida). &lt;i&gt;Nearchinotodelphys indicus&lt;/i&gt; Ummerkutty, 1960 (ex Archinotodelphyidae) is transferred to the Mantridae. It is suggested that the bivalve-inhabiting mantrids have diverged from the ascidicolous lineage leading to the Notodelphyidae and Ascidicolidae.

The density distribution of meroplanktonic larvae is compared with the density distribution of adults in the benthos, at five coastal stations in the Southern Bight of the North Sea (&lt;i&gt;Abra alba&lt;/i&gt; community). Plankton communities were sampled during one tidal cycle, along a buoy traject or at a fixed point; southern and northern locations, 250 m from each central sampling point, have been investigated too. Benthos samples were taken only at the central points of this traject. Meroplankton consisted of polychaete larvae (9 families) and bivalve and echinoderm larvae. The highest density values of these larvae (6,400 ind.10.25 m&lt;sup&gt;2&lt;/sup&gt;) are found on the southern sites of each traject (closest to the coastline). The highest...

Decapsulated &lt;i&gt;Artemia&lt;/i&gt; cysts have been evaluated as a direct food source for larvae of the carp &lt;i&gt;Cyprinus carpio&lt;/i&gt; L. All decapsulated cyst diets gave excellent survival of carp larvae during the first two weeks of culturing. Unlike traditionally brine-stored decapsulated cysts, dried &lt;i&gt;Artemia&lt;/i&gt; embryos provided growth results comparable to those obtained with freshly hatched &lt;i&gt;Artemia&lt;/i&gt; nauplii.

Zooplankton grazing pressure in the Oosterschelde (the Netherlands)
Provedor de dados: 27
Autores: Tackx, M.; Bakker, C.; Van Rijswijk, P.
Grazing activity by the dominant zooplankton species in the Oosterschelde (SW Netherlands) was studied as part of an ecological survey accompanying the construction of a storm-surge barrier at the mouth of this tidal inlet. At station WEST, situated at the mouth, potential grazing pressure by the zooplankton amounted to 6% d&lt;sup&gt;-1&lt;/sup&gt; of the phytoplankton standing stock and 18% of the primary production. At station EAST, in the inland part, 16% of the phytoplankton standing stock and 11% of the primary production was potentially consumed daily. Because the dominant zooplankton species in the inland part (&lt;i&gt;Acartia&lt;/i&gt; spp. and cirriped nauplii) tended to feed more on small particles than the dominant species in the seaward part...

Organochlorines in different fractions of sediments and in different planktonic compartments of the Belgian continental shelf and the Scheldt estuary
Provedor de dados: 27
Autores: Delbeke, K.; Joiris, C.R.; Bossicart, M.
PCB levels in sediments (bulk and fraction &lt;63µm), suspended matter and zooplankton from the Belgian continental shelf of the North Sea and the Scheldt estuary were educated in relation to their organic carbon content, their lipid content and, for sediments, their particle size distribution. PCB accumulation mechanisms are discussed, considering the importance of direct contamination (absorption onto the cell surfaces, absorption through the cell walls and partitioning into the cell lipids) for suspended matter and sediments, and of indirect contamination through the food for zooplankton. Geographical and seasonal variations are described.

On suspended barite and the oxygen minimum in the Southern Ocean
Provedor de dados: 27
Autores: Dehairs, F.A.; Goeyens, L.; Stroobants, N.; Bernard, P.; Goyet, C.; Poisson, A.; Chesselet, R.
Particulate Ba profiles were measured in the Indian sector of the southern ocean. The largest fraction (&gt;80%) of this barium is present as barite microcrystals. The profiles of total barium are characterized by a subsurface maximum between 200 and 500 m depth in the vicinity of the oxygen minimum. Highest barium values are found just south of the Polar Front, while lowest values occur close to the Antarctic Divergence. Between the divergence and the Polar front a tight inverse relationship is observed between oxygen in the oxygen minimum and barium in the barium maximum. This relationship disappears north of the Polar Front. Since suspended barite is known to be of biological origin, the correlation of barite with oxygen suggests that the observed...

Sand gobies are extremely abundant in coastal waters and estuaries. &lt;i&gt;Pomatoschistus lozanoi&lt;/i&gt; tends to be overlooked due to identification problems. This paper summarizes the characteristics to distinguish &lt;i&gt;P. lozanoi&lt;/i&gt; from &lt;i&gt;P. minutus&lt;/i&gt; and presents a new distinctive feature that allows identification of juveniles from 15-20 mm standard length onward. The known geographic distribution of &lt;i&gt;P. lozanoi&lt;/i&gt; is extended northward to 53°30'N and southward to 40°N on the coast of Europe. In northern Europe &lt;i&gt;P. lozanoi&lt;/i&gt; seems better adapted to the estuarine habitat than previously thought.

Improvement of the semiautomated headspace analysis method for the determination of methylmercury in biological samples
Provedor de dados: 27
Autores: Lansens, P.; Baeyens, W.F.J.
An improvement in the extraction step in the method of Decadt et al. for determining methylmercury in biological tissues is described. The methylmercury is released from the tissue by use of sulphuric acid as the cleaving agent and immediately converted to the iodide form by iodoacetic acid. These reaction steps take place in a closed headspace vial. The methylmercury iodide is then headspace-injected into a gas-chromatograph and detected with a microwave-induced plasma detector. Quantitation is accomplished by standard addition. Analysis of one sample takes less than 15 min. The detection limit of the method is 20 ng methylmercury per gram biological tissue when 50 mg of tissue are taken.

In our paper on seaweeds of the Snellius-II expedition (Coppejans &amp; Prud'homme van Reine, 1989) we suggested that the new species &lt;i&gt;Rhipilia nigrescens&lt;/i&gt; had been described in Phycologia. Due to regulations of that journal and corroborated by the short spell between acceptance and publication in Blumea, the Latin description can no longer be expected to be published as suggested. To validate the name of the new species a Latin description of the holotype is published here.

Two new Desmodoridae species are described: Croconema otti sp. n. and &lt;i&gt;Pseudochromadora incubans&lt;/i&gt; sp. n. The cuticular ornamentation and somatic setae of &lt;i&gt;C. otti&lt;/i&gt; sp. n. display features previously unknown within the genus. In &lt;i&gt;P. incubans&lt;/i&gt; sp. n. the position of the cephalic setae and latero-subdorsal amphids on the cephalic capsule, which is divided into two sections, are characteristic. Brood protection occurs in both species. In &lt;i&gt;C. otti&lt;/i&gt; sp. n. a single line of similar embryos is attached laterally on the left side of the body.

For some years now the parasitic swim bladder nematode &lt;i&gt;Anguillicola crassus&lt;/i&gt; of the European eel &lt;i&gt;Anguilla anguilla&lt;/i&gt; L., has been reported from several European countries. The entire life history of this parasite has recently been elucidated in our laboratory. Young larvae leave the swim bladder of the host via the pneumatic duct and reach the water through the digestive tract. They are ingested by small copepods (Cyclopoida), which act as intermediate hosts. Larvae remain in the hemocoel until the copepods are eaten by the final host, the European eel. Larvae penetrate through the intestinal wall and reach the swim bladder where they develop into adults. When infected copepods are eaten by other small fish, such as carp...

The First International Conference on Oceanography (Brussels, 1853)
Provedor de dados: 27

M. F. Maury, head of the U.S. Naval Observatory. started to compile meteorological and sea surface data from the logbooks. This allowed him, during the 1840's to expand knowledges in descriptive oceanography. Willing to extend the geographical coverage of his data bank and chartings, Maury wanted to involve merchant navy as well as ships from other nations. This led him to consider favourably projects of universal networks for meteorological data collection such as proposed by the Russian Kupffer in the early 1850's. Maury tried to establish such co-operation when British and US officials came together to uniformize their network. Maury did not succeed to bring the project at an international level. Instead, he only was allowed to call upon an...

Grain size-, facies- and sequence analysis of West Belgian Eocene continental shelf deposits
Provedor de dados: 27
Autores: Jacobs, P.; Sevens, E.; De Batist, M.; Henriet, J.-P.
Grain size trends and sedimentary structures of Eocene continental shelf deposits from offshore and onshore drillings in West Belgium were combined for reconstruction of depositional environments.The VAIL-model for siliciclastic sedimentation on shelf margins allows systems tracts identification on basis of grain size signals. The (put into revision) Eocene lithostratigraphy could therefore be transferred into sequence stratigraphy.Sediment genetic interpretation of sedimentary structures and grain size trends, together with sediment supply indications, suggests a Pre-Rhine-Meuse-Scheldt delta high on the shelf as depositional system.

(1) Based on vegetation relevés of sample units along transects perpendicular to the coastline, the mangal ecosystem of Gazi Bay (Kenya) has been investigated.(2) An indirect gradient analysis is performed by the ordination method Detrended Correspondence Analysis.(3) The first ordination axis can be interpreted in terms of resistance of the different species to flooding.(4) A similar zonation pattern is found as described by Walter &amp; Steiner (1936).(5) Zonation is closely connected with morphological and ecophysiological features of the mangrove species. Therefore stomatal density has been measured. &lt;i&gt;Sonneratia&lt;/i&gt; has by far the lowest stomatal density, &lt;i&gt;Lumnitzera&lt;/i&gt; the highest.

Autores: Coutteau, P.; Lavens, P.; Sorgeloos, P.
In this study baker's yeast was evaluated as a substitute for live &lt;i&gt;Dunaliella tertiolecta&lt;/i&gt; algae in the culture of the brine shrimp &lt;i&gt;Artemia&lt;/i&gt; . Consumption of fresh baker's yeast resulted in poor growth and survival of brine shrimp. However, the nutritional value of the yeast significantly improved after complete removal of the yeast cell wall by enzymatic treatment. Baker's yeast was also made digestible for &lt;i&gt;Artemia&lt;/i&gt; by simple chemical treatment which did not reduce rigidity of the yeast cell. The external mannoprotein layer of the yeast cell wall is probably the major barrier to digestion by &lt;i&gt;Artemia&lt;/i&gt; .

Diversity of the nematode communities in the Southern Bight of the North Sea
Provedor de dados: 27
Autores: Vincx, M.
The nematode communities from 102 stations in the Southern Bight of the North Sea, sampled between 1972 and 1984, are examined. Overall, 456 species, belonging to 159 genera and 37 families were found. Sediment structure and chlorophyll a content were found to be determining environmental factors in the species composition of the nematode communities. Diversity is determined at different levels of the nematode community; &lt;i&gt;i.e&lt;/i&gt;. species diversity of the whole community, species diversity of eight dominant families (Chromadoridae, Comesomatidae, Cyatholaimidae, Desmodoridae, Microlaimidae, Oncholaimidae, Thoracostomopsidae and Xyalidae), species diversity of the four feeding types, family diversity and trophic diversity within the whole...

Distribution and adaptations of sea ice inhabiting &lt;i&gt;Harpacticoida&lt;/i&gt; (Crustacea, Copepoda) of the Weddell Sea (Antarctica)
Provedor de dados: 27
Autores: Dahms, H.-U.; Bergmans, M.; Schminke, H.K.
Seven harpacticoid species were found to be associated with sea ice collected during 5 Antarctic cruises of the &lt;i&gt;RV Polarstern&lt;/i&gt;. Their distribution within the fast ice and pack ice zones of the Weddell Sea is presented. Whereas some individuals probably become entrapped into the ice only accidentally, at least 4 species are genuinely sympagic. These have evolved remarkable adaptations, as evidenced by field and laboratory studies of &lt;i&gt;Drescheriella glacialis&lt;/i&gt;, which is by far the most abundant. Such adaptations include: the ability to penetrate deep into ice; a comparatively high salinity tolerance allowing it to endure large salinity fluctuations associated with ice crystal formation and melting; good swimming ability,...

Comparison of the fatty acid profile of wild caught fingerlings and yolk sac sea bass (&lt;i&gt;Dicentrarchus labrax&lt;/i&gt;) larvae with cultured healthy larvae and larvae suffering from whirling disease
Provedor de dados: 27
Autores: Corneille, S.; Agius, C.; Ollevier, F.P.
Analysis of the fatty acids of total lipids of wild fingerlings (1-4 g) of sea bass (&lt;i&gt;Dicentrarchus labrax&lt;/i&gt;) caught off the northcoast of France shows that more than 30% of total fatty acids consists of the two essential fatty acids eiopentaenoic (C20:5 n-3) and docosahaenoic (C22:6 n-3) acids. One- and three-day old yolk sac larvae have even higher amounts of these two important fatty acids (about 40%). On the other hand, laboratory-reared 60-day old larvae had much lower concentrations of C20:5 n-3 (4% of total fatty acids) and C22:6 n-3 (5,5% of total fatty acids). In larvae suffering from whirling or spinning disease the percentage of C20:5 n-3 was only 2,8% and only traces of C22:6 n-3 were found. These results emphasize the...

An improved method for artificial infection of the European eel, &lt;i&gt;Anguilla anguilla&lt;/i&gt;, with &lt;i&gt;Anguillicola crassus&lt;/i&gt; (Nematoda, Dracunculoidea)
Provedor de dados: 27

A standardized method was developed for artificially infecting the European eel with &lt;i&gt;Anguillicola crassus&lt;/i&gt;, a parasitical swim bladder nematode. For this purpose, an intermediate host, &lt;i&gt;Paracyclops fimbriatus&lt;/i&gt;, and a paratenic host, &lt;i&gt;Cyprinus carpio&lt;/i&gt;, were used. Parasite prevalence in the artificially infected eels was very high, although there was a large variation in the number of worms per eel. Compared to other methods of artificial infection described in the literature, this method appears to be more efficient ad reliable; there were also more infectious larvae that were recovered and the mortality rate of eels under treatment was lower.

Provedor de dados: 27
Autores: Coutteau, P.; Lavens, P.; Léger, P.; Sorgeloos, P.
The development of a cost-effective algal substitute would greatly reduce operating costs of bivalve hatcheries and has therefore been the subject of many studies. Previous work has resulted in the development of a yeast diet with improved digestibility and nutritional composition. Preliminary trials showed that this diet can substitute up to 80% of the algal diet in the seed culture of the Manila clam &lt;i&gt;Tapes semidecussata&lt;/i&gt;. In this communication we propose a culture test diet which will be used to study further dietary improvements of the yeast product.Juveniles of the Manila clam (1 to 5 mg unit weight) were batch cultured in a 51 recirculating system.

Sustainable and Conventional Agriculture in South-Eastern Australia - A Comparison
Provedor de dados: 21
Autores: Wynen, Els.
A survey of sustainable cereal/livestock farmers in South-Eastern Australia in 1985-86 is described in this study.     The first conclusion is that the average net financial results of producers who farm without the use of synthetic fertilisers and pesticides can not be seen to be different from those obtained on comparable conventional farms in 1985-86.      The sustainable farms were in areas with similar climate and soil quality (as measured by improved capital value per hectare) to that of their conventional counterparts. The use of less fertilisers per cropped unit of land on sustainable farms is therefore not due to the intrinsic quality of the land, but to a conscious decision to adopt an approach to farming very different from the conventional...

Autores: Pannell,   David J.
A biologically realistic model of crop yield response to herbicide application is presented. It includes functions for weed mortality from herbicide application and yield loss due to surviving weeds. The optimal herbicide rate and two types of decision thresholds are derived theoretically and illustrated with empirical examples. Responses of the various decision criteria to changes in parameters are also examined theoretically and empirically. A multidimensional threshold for weeds based on weed density and weed-free yield is presented. The issue of farmers using other than officially recommended herbicide rates is discussed.

A transshipment model of the Northeast dairy sector is developed to assess the potential for structural change in the manufacturing industry. It is detennined that the reduction of existing hard product processing capacity near metropolitan areas would diminish total costs. Industry-wide savings of about 60 million dollars annually would be realized by fluid, soft product, cheese and butter/powder manufacturers. The model points to finn level as well as industry level incentives to move toward a more concentrated dairy manufacturing sector in the Northeast.

PUBLIC CHOICE THEORY AND AUSTRALIAN AGRICULTURAL POLICY REFORM
Provedor de dados: 31
Autores: Martin,   William J.
Recent discussion of the process of policy reform has tended to focus on public and private interest theories of public choice as alternative models. The analysis of Australian agricultural policy presented in this paper draws on several extensions of the private interest model including the contractarian framework, extra-rational considerations such as moral attitudes and the desire to participate. Recent agricultural policy reforms in Australia are examined in the light of those theories. This examination highlights the importance of ideas and changes in the rules for policy formulation in influencing policy outcomes. In some cases the private interest theory appears to offer an adequate explanation while, in others, it provides only a partial...

Packaging potatoes in institutional size retort pouches is analyzed as a possible market outlet for Michigan potatoes.  A two-pronged research approach involves estimation of unit costs of retort pouch potato products (RPP) and an assessment of the market potential for RPP in the food service industry.  Break-even costs for a six-pound pouch is estimated to be $2.62 (44¢ per pound), which translates to a likely price disadvantage relative to competing products.  Food service operators expressed general satisfaction with existing potato products and will not readily switch to use of retort pouch potato products.

The economic impacts of recreational visits to state parks on the economies of North Carolina, South Carolina, Georgia, and Tennessee were estimated using the U.S. Forest Service IMPLAN input-output modeling system. Recreational expenditure data associated with state parks were obtained from the Public Area Recreation Visitors Study (PARVS). Results suggest that recreational spending may stimulate a considerable amount of economic activity in the state economies studied. Hence, future research into the economic development potential of outdoor recreation seems warranted.

THE EFFECTS OF CHANGES IN THE TAX STRUCTURE ON AGRICULTURAL ASSET REPLACEMENT
Provedor de dados: 31
Autores: Smith,   Vincent H.
This paper uses a deterministic asset replacement model to examine the implications of the 1986 Tax Reform Act (TRA) for replacement investment in U.S. agriculture. The optimal replacement age for an asset is shown to be inversely related to the size of investment tax credits and the present value of depreciation allowances but generally directly related to marginal tax rate. Simulation results indicate that the net effects of the TRA vary across assets. Replacement ages for assets with relatively long depreciation lives (e.g., farm structures) tend to fall. Those for assets with relatively short depreciation lives rise (e.g., tractors).

Optimal Trade Policies for a Developing Country Under Uncertainty
Provedor de dados: 31
Autores: Choi,   E. Kwan; Lapan,   Harvey E.
This paper investigates optimal trade policies for a developing small open economy which faces international price uncertainty. Trade taxes are used to finance provision of a public good, which enters the utility function of consumers. If demands for private goods are independent of the public good, the optimal composite tariff dominates the optimal quota. If the optimal state-contingent tariff increases with the foreign price, the optimal specific tariff also dominates the optimal quota, regardless of risk aversion. However, the ranking of the optimal specific tariff and the optimal quota generally depends on risk attitudes as well as ordinal preferences.

The Almost Ideal Demand System Approximation and Separability
Provedor de dados: 31
Autores: Brown,   Mark G.; Lee,   Jonq-Ying.
The paper focuses on separability in the almost ideal demand system (AIDS) in time series analysis.  The AIDS approximation based on Stone's price index is specified in terms of the Rotterdam model and block additivity is imposed for illustrative purposes.  A generalization to other types of separability is then considered.  The model can be viewed as an extension to Theil et al.'s Working-PI time series model.  In both the Theil et al. model and the AIDS model examined here, the marginal propensity to spend on a good is allowed to depend on the good's budget share.  In the model in this paper, the Slutsky coefficients are further allowed to depend on the budget shares.  The model provides a consistent way to analyze subgroup demand relationships.

Tariff reform in the presence of sector-specific distortions
Provedor de dados: 31
Autores: Beghin,   John C.; Karp,   Larry S.
The problem of choosing second-best trade policies is modified by including sector-specific policies as well as tariffs. We obtain conditions under which reduction of the largest tariff is welfare improving. Formulae for the optimal tariff and sector-specific subsidy are used to study the design of optimal policy menus. The theory is illustrated by an empirical general equilibrium model of the U. S. economy which emphasizes agriculture. The model suggests that reductions in agricultural protection in the United States would be welfare improving.

Provedor de dados: 31
Autores: Brown,   Mark G.; Lee,   Jonq-Ying; Behr,   Robert M.
Demand relationships for two closely related products -- grapefruit juice and grapefruit-juice cocktail -- were estimated from grocery-store scanner data to analyze the contention that consumer confusion exists between the two products.  Results suggest confusion may exist, with grapefruit-juice advertising not only increasing the demand for grapefruit juice but also for grapefruit-juice cocktail.

COMMON PROPERTY RESOURCES IN A GLOBAL CONTEXT
Provedor de dados: 31
Autores: Runge,   C. Ford.
The "global commons" is a metaphor. Metaphorically, all of the earth's resources are held in common by this and future generations, to be used and abused as we and our heirs see fit. Yet "the commons" metaphor may also be seen at a less global level, and less metaphorically. In much of the developing world, common property provides a complex system of norms and conventions regulating individual use rights to a variety of natural resources, including forests, grazing lands, fisheries and water resources.  This article will examine both macro-level issues of the commons, and micro-level cases, with emphasis on developing countries. Macro-level issues involve problems of international governance, while micro cases involve local management of natural and human...

STRUCTURE OF SOUTH CENTRAL AGRICULTURAL PRODUCTION
Provedor de dados: 31
Autores: Polson,   Rudolph A.; Shumway,   C. Richard.
Using a dual economic specification of a multiproduct technology, the structure of agricultural production was tested for five South Central states (Texas, Oklahoma, Arkansas, Mississippi, and Louisiana). A comprehensive set of output supplies and input demands comprised the estimation equations in each state. Evidence of nonjoint production in a subset of commodities was detected in four of the five states. Several commodities also satisfied sufficient conditions for consistent aggregations. However, the specific outputs satisfying each structural property varied by state. Sufficient conditions for consistent geographic aggregation across the states were not satisfied. These results provide empirical guidance and important cautions for legitimately...

Crop Management Decision Making: Information Used and Required By Manitoba Crop Producers
Provedor de dados: 31
Autores: Zbeetnoff,   Darrell M.; Jeffrey,   Scott R.
As part of the project entitled "Management Options for Grain Production in the 1980s and 1990s", a farmer survey was conducted during the fall and winter of 1988-89. A total of 234 Manitoba crop producers were interviewed, and asked questions concerning the information used and required in making specific crop management decisions. The survey respondents were asked questions pertaining to the following management decisions: 1. fertilizer rates, and method/timing of nitrogen application, ii. method/timing of pesticide application, 111. varietal selection for wheat and canola, and iv. canola acreage decisions. In each case, farmers were requested to provide actual practices, information used in making decisions, and perceived information gaps. Producers...

Systematic and Unsystematic Risk Costs for Southeastern Kansas Farm Enterprises
Provedor de dados: 31
Autores: Amegbeto,   Koffi N.; Featherstone,   Allen M.
Six measures of farm returns are used to estimate the most "appropriate" market index for southeastern Kansas farms. Systematic and nonsystematic risks and risk costs are estimated for farm planning. Results suggest that regional indices are more appropriate for use as the market index than state indices.

CHANGING FORCES AFFECTING RURAL COMMUNITIES IN THE 1980'S AND POLICIES TO HELP DEAL WITH THOSE FORCES
Provedor de dados: 31
Autores: Peltola,   Asko Antero.
The number of farms in industrialized countries has been declining continuously over the last few decades. The transition from an agrarian to an industrial society is a complex process involving many consequences to the economy as a whole and particularly to rural regions and communities. The industrial countries have tried to cushion the adjustment process, mostly by using agricultural policy tools, but they have proved to be incapable of preserving the viability of rural areas and recognizing their increasing diversity.   In the U.S., the 1980s reversed the favorable rural growth trends of the seventies. The nonmetro population growth slowed and the traditional sectors of rural areas suffered from unfavorable trade conditions and from the recession of...

DICHOTOMOUS-CHOICE, CONTINGENT-VALUATION QUESTIONS: FUNCTIONAL FORM IS IMPORTANT
Provedor de dados: 31
Autores: Boyle,   Kevin J.
A variety of questioning formats have been used in contingent-valuation studies, with dichotomous-choice questions becoming the preferred format.  However, as with any empirical technique, continued applications raise questions that require attention if the credibility of the procedure is to be maintained.  It is shown that estimated Hicksian surplus can be substantially affected by the selection of a functional form when analyzing responses to dichotomous-choice questions.  Given that theory, intuition, and empiricism all play a role in developing these estimates, several maxims are suggested for evaluating and/or mitigating such effects in future studies.

By 1850, New South Wales (NSW) appeared to have entered a period of long term economic stability which was almost entirely dependent on the production of fine wool. The prospects of such a future vanished with the discovery of large quantities of alluvial gold in 1851. The population of the colony almost doubled, increasing from 179,000 in 1851 to 351,000 in 1861 (Vamplew 1987, p. 26).

Autores: Dinar,   Ariel; Yaron,   Dan.
This article describes the influence of input quality and scarcity, environmental conditions, human capital, water price, and other variables on adoption rates for modern irrigation technologies in terms of both speed and extent of application. An empirical model is developed to apply these relationships to citrus groves in Israel. Results show that modern irrigation technologies tend to be adopted sooner and to a greater extent (a) on groves located on relatively low quality land, (b) in regions with higher evaporation rates, (c) on groves planted with more sensitive rootstock, and (d) on groves grown under conditions of restricted water allotments and higher water prices. Management, human capital, and scale of operation also affect the level and speed...

MARKETING INFORMATION AS A CONSTRAINT TO LOCALLY GROWN PRODUCE: EVIDENCE FROM OHIO
Provedor de dados: 31
Autores: Jones,   Eugene; Batte,   Marvin T.; Schnitkey,   Gary D.
A random sample of 200 Ohio fruit producers were surveyed in January 1988, regarding their use of information for decision making.  Survey responses were used to determine if improved marketing information increases the likelihood of Ohio fruit producers gaining a larger share of Ohio's produce market.  Results from the production adequacy equations show that larger producers and those marketing a predominate share of their fruit through wholesalers and retailers are the ones most likely to agree that their fruit production is limited by insufficient marketing information.  These results suggest an opportunity for Ohio to gain a larger share of the produce market.

EFFECT OF CONTRACT DISCLOSURE ON PRICE:  RAILROAD GRAIN CONTRACTING IN THE PLAINS

Autores: Fuller,   Stephen W.; Ruppel,   Fred J.; Bessler,   David A.
The Staggers Rail Act of 1980 granted railroads freedom to establish rates and enter into confidential contracts with grain shippers. Recent legislation (1986) required that certain contract terms be disclosed. This study shows rail rates in the Plains region commenced an upward trend after implementation of the disclosure policy. Results suggest contract disclosure and increased reliance on posted tariffs facilitated rate coordination within the oligopolistic railroad industry.

Autores: Gineo,   Wayne M.; Omamo,   Steven Were.
This paper develops Engel relationships to identify the determinants of household expenditures on nursery products and specifies their impact on consumer purchases of these goods for subregions of the United States. Household income, the number of single family home construction starts, educational level attained, and age composition of the population were found in influence nursery product expenditures. The economic variables of income and construction starts appear to be key factors affecting nursery purchases. To maintain a competitive edge, industry participants should monitor these variables carefully and adjust their production and marketing plans to meet changing market conditions.

IMPACT OF NOMINAL AND REAL PRICE CHANGES ON THE SWEET POTATO PACK IN LOUISIANA
Provedor de dados: 31
Autores: Hinson,   Roger A.
Changes in consumer demand have led to a prolonged decline in per capita consumption of sweet potatoes, both fresh and processed form. With a product line of various container sizes and styles, processors may respond to changes by altering product line composition to enhance sales. Changes in quantity of individual products were contrasted to changes in nominal and real prices. Quantities were not consistently related to real prices in an inverse manner, though recent increases in total production of canned sweet potatoes have occurred while real price has decreased.

Autores: Onafowora,   Olugbenga; D'Souza,   Gerard E.; Colyer,   Dale.
A disaggregated econometric model of the agricultural sector at the state level is constructed.  Using time series data on West Virginia agriculture and three-stage least squares in estimation, the model is employed to examine how various components of the state's agricultural sector adjust to changes in certain price and nonprice variables.  Results reveal characteristics of the state's agricultural economy that are both unique and useful - characteristics that are usually masked in aggregate models but that have profound implications for modeling producer decision making and policy formulation.

The results of a three-year study to establish baseline estimates of the importance of wholesale produce markets (WPM) are reported. It is estimated that a third of all produce marketed in the United States and Canada goes through WPM. These facilities tend to be most important in larger urban areas. Gate and unloading fees commonly charged at WPM may place them at a competitive disadvantage relative to off-market sites.

Autores: White,   Fred C.; Araji,   A.A.
The decision-making process by which academic departments within an experiment station allocate funds among commodities is examined. The decision to conduct research on some commodities and not on others introduces a problem of censored dependent variables. In order to overcome this problem, a simultaneous equations model with selectivity was used; it was applied to data from the Idaho Experiment Station. The results indicated a simultaneous relationship between research funding levels and expected benefits. Marginal products of one dollar in research investment were $53.80 for applied research, and $8.49 for maintenance research.

A SOCIOECONOMIC ANALYSIS OF MARKETING INFORMATION USAGE AMONG OHIO FRUIT PRODUCERS
Provedor de dados: 31
Autores: Jones,   Eugene; Batte,   Marvin T.; Schnitkey,   Gary D.
Farm producers attempt to mitigate risk and uncertainty by utilizing accurate and reliable information. This research attempts to identify sources of information used by Ohio fruit producers and then determine which of these sources are best meeting their information needs. Results are based on a logit analysis of Ohio fruit producers and several factors are shown to influence producers' evaluation of the "adequacy" of their marketing information. Among these factors are age, business size, education, type of enterprise, and types of information sources. Reported findings have implications for marketing efficiency, particularly if producers' evaluation of information as adequate is positively related to its efficient use.

BOTSWANA'S APPROACH TO DROUGHT:  HOW DISASTER RELIEF CAN BE DEVELOPMENTAL
Provedor de dados: 31
Autores: Siegle,   Joe.
Integrating disaster relief and development is not a new concept. Addressing underlying problems that have made a society susceptible to disaster have their origins dating back to the Indian Famine Relief Codes of the 1860's. Today, this is a popular notion among many people involved with emergency response. Still, there are relatively few instances where disaster relief has emphasized both long and short term needs - cases from which other countries and international organizations can learn. The problem of not having a successful example from which to model relief responses has often been cited as creating a serious barrier to implementing successful relief-development responses during recent famines (Cutler and Stephenson, RDI, Garvelink). The need for...

Local labor market characteristics are theoretically relevant to the determination of off-farm earnings of farm operators, but the empirical analysis of these effects has been hindered by a lack of appropriate data. This study employs the new census public use micro-data sample, PUMS-D, to investigate the effect of local labor market characteristics on off-farm earnings of farm operators. The PUMS-D data allow local characteristics to be defined on a labor market area basis, rather than on a political boundary basis. For a sample of Georgia farm operators, local labor market size, unemployment rates, and industrial structure were found to have significant impacts on off-farm employment and earnings.

There's no such thing as free housing for hired agricultural workers
Provedor de dados: 31
Autores: Perloff,   Jeffrey M.
One-quarter of hired agricultural workers live in housing that is provided without rent. whereas few workers in other industries are provided with rent-free housing as part of their employment compensation. Workers who live in rent-free housing are paid more than comparable agricultural workers. possibly reflecting the low-quality and isolation of such housing.

Breaking the Incrementalist Trap: Achieving Unified Management of the Great Lakes Ecosystem
Provedor de dados: 31
Autores: Allee,   David J.; Dworsky,   Leonard B.
Policy evolution was characterized by Charles Lindblom three decades ago as "fragmented, disjointed incrementalism. " He argued incrementalism made the best use of very limited theory and data upon which to base decisions. This was a maj or intellectual challenge to the advocates of comprehensive planning based upon scientific principles and analysis. The result has been further research on how to achieve effective strategic policy innovations. Of special relevance to the Great Lakes has been recent research stimulated by the prospect of global climate change. We combine it with the results of a seminar that has simulated the application of ecosystem planning to the Great Lakes, and use the synthesis to illustrate that the prerequisites for nonincremental...

THE DEMAND FOR FLUID MILK PRODUCTS IN THE U.S.:  A DEMAND SYSTEMS APPROACH
Provedor de dados: 31
Autores: Gould,   Brian W.; Cox,   Thomas L.; Perali,   Carlo Federico.
The demand for fluid milk products has changed dramatically in recent years not only in terms of lower levels consumed but also in terms of the composition of the products consumed.  A time-series based demand system analysis of the market for lowfat and whole milk products is developed incorporating the effects of changes in prices and demographic characteristics.  From the estimated model, the impacts of future changes in the demographic profile of the U.S. population on fluid milk demand are analyzed.

This paper outlines DEBET (Decision Based Economic Theory), a method for determining revealed preferences of governments. DEBET is applied to US wheat policy decisions in the 1980s. This method has a number of advantages over alternative approaches to the analysis of revealed preferences of government. It makes use of information contained in policy alternatives contemplated but not agreed upon, and it is suitable for modeling the discrete - continuous choice problem of policy makers in a multi-instrument context.

Adoption of Soil Conservation Measures in Manilla Shire, New South Wales
Provedor de dados: 31
Autores: Sinden,   Jack A.; King,   David A.
Land in Manilla Shire, New South Wales, is characterised by serious soil erosion and land use is characterised by high rates of adoption of the recommended soil conservation measures. This behaviour is analysed to attempt to determine what factors are promoting soil conservation at each stage in the adoption process. The results suggest that policies to promote farmer perception of erosion problems should be formulated differently from those to promote actual adoption of the recommended measures. Perception of the problem depends mainly on the percentage of farm area that is eroded, but the likelihood of adoption depends mainly on the intensity of the erosion. The farmer's rating as an investor, the size and security of farm income, and the presence of...

AN INVESTIGATION OF DIFFERENCES IN AGRICULTURAL EXPENDITURE BY STATE GOVERNMENT
Provedor de dados: 31
Autores: Ospina,   Enrique; Gunderson,   Ralph O.
Agriculture department programs in 43 states surveyed offer similar services in regulation, market promotion, and natural resource conservation but are organized differently. Two OLS equations were estimated to explain state agriculture department expenditures as a function of gross farm sales, farm receipts mix, degree of government centralization, the proportion of metropolitan area residents, and tax capacity. A positive relation was found between state agricultural spending and gross farm sales and the percent of fruit/vegetables farm receipts. However, the results cast doubt over the Leviathan thesis of increasing government spending resulting from bureaucratic power.

AN ECONOMIC ANALYSIS OF THE U.S. GENERIC DAIRY ADVERTISING PROGRAM USING AN INDUSTRY MODEL
Provedor de dados: 31
Autores: Liu,   Donald J.; Kaiser,   Harry M.; Forker,   Olan D.; Mount,   Timothy D.
The market impacts of generic dairy advertising are assessed using an industry model which encompasses supply and demand conditions at the retail, wholesale, and farm levels, and government intervention under the dairy price support program.  The estimated model is used to simulate price and quantity values for four advertising scenarios: (1) no advertising, (2) historical fluid advertising, (3) historical manufactured advertising, and (4) historical fluid and manufactured advertising.  Compared to previous studies, the dairy-industry model provides additional insights into the way generic dairy advertising influences prices and quantities at the retail, wholesale, and farm levels.

ESTIMATING SOURCES OF FLUCTUATIONS IN THE AUSTRALIAN WOOL MARKET: AN APPLICATION OF VAR METHODS
Provedor de dados: 31
Autores: Myers,   Robert J.; Piggott,   Roley R.; Tomek,   William G.
Vector autoregression (VAR) methods are used to analyse the contribution of supply, demand and policy shocks to unpredictable fluctuations in the market for Australian wool. VAR procedures are compared with conventional structural econometric models as methods for decomposing sources of instability. While each has advantages and disadvantages, VAR procedures might be viewed as preferable when the underlying market structure is complex and uncertain, as it is in the case of wool. Based on the results obtained, demand shocks are the dominant source of uncertainty in the wool market in the absence of Australian Wool Corporation intervention, but intervention has blunted their effects, reducing market uncertainty and increasing the average level of prices and...

UNCERTAINTY, PRICE STABILIZATION AND WELFARE
Provedor de dados: 31
Autores: Choi,   E. Kwan; Johnson,   Stanley R.
This paper investigates whether a small country facing foreign price instability benefits from active stabilization of the domestic price of the importable. If the random tariff revenue is rebated ex post, domestic price stabilization increases income instability, and nonintervention is optimal. If an ex ante rebating scheme is employed, a small country can benefit from domestic price stabilization, and there exists a partial stabilization policy that dominates free trade. Partial stabilization of the domestic price with the ex ante rebate requires a variable import levy inversely related to the foreign price.

Agricultural Policies and the GATT: Reconciling Protection, Support and Distortion
Provedor de dados: 31
Autores: de Gorter,   Harry; Harvey,   David R.
This paper analyzes the relationship between the theory of protection, farm income support and international trade distortion. To parallel those of protection, a measure of distortion is derived which compares trade volumes under support policies with those which would occur under multilateral free trade. Estimates are made of these measures for the European Community and the United States for a selection of commodities. The relationship between measures of protection and economic efficiency is also highlighted. The conclusion is that present measures of protection such as the Producer Subsidy Equivalent are confusing as measures of either trade distortion or income support. Some implications are drawn for the GAIT negotiations on agriculture and for the...

DYNAMIC REGIONAL ANALYSIS OF THE CALIFORNIA ALFALFA MARKET WITH GOVERNMENT POLICY IMPACTS
Provedor de dados: 31
Autores: Konyar,   Kazim; Knapp,   Keith C.
Alfalfa's heavy reliance on irrigation water and its role as an alternate to program crops makes it susceptible to changes in government farm policies. This article presents a dynamic spatial equilibrium model of the California alfalfa market. The model is used to forecast alfalfa acreage, prices paid and received, and transportation flows for the short run and the long run under the base year conditions. The base year results then are compared to a situation of changing demand due to reductions in federal water subsidies and the implementation of a cotton acreage-reduction program.

The purpose of the research on which this report was based was to determine the projected impact that an aging American market could have on retail food stores.  A survey was sent to 2,600 households resulting in a total of 721 responses.  The data were analyzed to determine present retail food store selection criteria and food purchasing behaviors compared with behaviors projected for the year 2000.  Several recommendations for food retailers were made based on the results of the survey.  The survey respondents did not project significant changes in store selection criteria between 1989 and the year 2000.  Service requirements did differ.  Home shopping and grocery delivery were projected to be more important in the year 2000.  Shopping and food...

Autores: Parliament,   Claudia; Lerman,   Zvi; Fulton,   Joan R.
A comparison of regional dairy cooperatives with investor-owned dairy firms from the period 1976-87 produced empirical findings that are at variance with the hypotheses suggested by the theory of cooperatives. The cooperatives in the sample performed significantly better than the IOFs when compared by leverage, liquidity, asset turnover, and coverage ratios, while the rate of return to equity was not found to be significantly different. Techniques are also proposed for valuing the nonmarket aspects of cooperatives that are not captured by financial ratio analysis.

AGRICULTURAL PRICES: THIRD WORLD DILEMMA
Provedor de dados: 31
Autores: Peterson,   Willis L.
Due to a lack of internationally comparable agricultural price data, implicit output/input price ratios are constructed as the reciprocals of input MPPs. The MPPs are estimated by a production function fitted to data from a world cross section of 119 countries. Although the output/purchased input price rations are substantially higher for the developed nations than the less developed countries, the opposite is true of the output/labor price ratio. The price of agricultural output relative to wages and per capita income is nearly three times greater in the third world than in the developed countries. Price and trade policies which maintain output prices in developing countries below world market levels are seen as a compromise between the low...

China's Economic Growth, Changing Comparative Advantages and Agricultural Trade
Provedor de dados: 31
Autores: Anderson,   Kym.
The rapid growth of the Chinese economy during the 1980s was accompanied by an equally rapid shift in China's comparative advantage towards light manufactures, such as textiles and clothing, at the expense of agriculture. If that economy were to resume the economic reform process that was stalled in 1988-89, its comparative advantages would move even further in that direction, following the pattern of its more industrialised neighbours. Dependence on agricultural imports - particularly feed grains, cotton and wool would rise unless domestic prices for farm products are increased substantially. Model simulation results are presented to support this conclusion (which is based on theory and historical experience) and to indicate the orders of magnitude that...

PREDATOR-PREY SYSTEMS IN PEST MANAGEMENT
Provedor de dados: 31
Autores: Harper,   Carolyn R.
The use of chemical pesticides frequently causes minor pests to become serious problems by disturbing the natural controls that keep them in check.  As a result, it is possible to suffer heavier crop losses after pesticides are introduced than before their introduction.  Efficient use of pesticides requires complete biological modeling that takes the appropriate predator-prey relationships into account.  A bioeconomic model is introduced involving three key species: a primary target pest, a secondary pest, and a natural enemy of the secondary pest.  Optimal decision rules are derived and contrasted with myopic decision making, which treats the predator-prey system as an externality.  The issue of resistance in the secondary pest is examined briefly.

PROBABILISTIC COST EFFECTIVENESS IN AGRICULTURAL NONPOINT POLLUTION CONTROL
Provedor de dados: 31
Autores: McSweeny,   William T.; Shortle,   James S.
Conceptual weaknesses in the use of costs of average abatement as a measure of the cost effectiveness of agricultural nonpoint pollution control are examined. A probabilistic alternative is developed. The focus is on methods for evaluating whole-farm pollution control plans rather than individual practices. As a consequence, the analysis is presented in a chance-constrained activity analysis framework because activity procedures are a practical and well developed device for screening farm planes. Reliability of control is shown to be as important as reduction targets in designing farm plans for pollution control. Furthermore, broad-axe prescriptions of technology in the form of Best Management Practices may perform poorly with respect to cost effectiveness.

The objective of this article is to estimate historical economic surpluses for the subsectors involved in the U.S. sugar market.  Annual producer and consumer surpluses were computed based on a five-equation model and 1958-87 data.  In the last decade, the welfare position of cane- and beet-sugar producers has been roughly maintained, the domestic consumer surplus and the export quasi-rents to foreign countries have both declined, and quasi-rents of the corn-sweetener industry now surpass those that accrue to the cane industry and are about the same as those of the beet-sugar industry.  Some policy implications are discussed.

Economics of Food and Safety: Risk, Information, and the Demand and Supply of Health

Autores: Falconi,   Cesar; Roe,   Terry L.
A model of expected utility maximization and a stochastic health production function are used to show how consumer's beliefs, the certainty of beliefs, and the presence of information affects demand for goods as they are driven by the demand for health. Then, it is shown that competitive markets fail to account for the health implications of substances in the production of a commodity that affects health, nor are incentives provided to inform consumers of substance concentrations and its implications to health. This result is shown to not necessarily follow in concentrated industries.

REGIONAL ADJUSTMENT RESPONSE IN THE U.S. DAIRY SECTOR TO CHANGES IN MILK SUPPORT PRICE
Provedor de dados: 31
Autores: Weersink,   Alfons; Howard,   Wayne H.
Milk production supply response at the regional level for the U.S. dairy sector is estimated through the use of dynamic dual models. Adjustment rates and elasticity measures are presented, and then the estimated parameter coefficients are used to stimulate shifts in production resulting from price changes. A drop in milk price designed to realign market conditions is projected to be borne largely by the Corn Belt and, to a lesser extent, the western states.

GRANGER CAUSALITY FROM THE EXCHANGE RATE TO AGRICULTURAL PRICES AND EXPORT SALES
Provedor de dados: 31
Autores: Bradshaw,   Girard W.; Orden,   David.
In-sample and out-of-sample Granger causality tests are applied to determine whether the real trade-weighted agricultural exchange rate helps predict monthly real prices and export sales of wheat, corn, and soybeans. An ARIMA model, alternative univariate and bivariate autoregressive models, and a restricted bivariate autoregressive model based on Hsiao’s procedure are specified for each variable. Results of the causality are shown to be sensitive to specification choice. Forecasting performance of the models is compared and out-of-sample Granger causality is determined using univariate and bivariate models with the best (lowest mean-square forecast error) forecasting accuracy. These tests provide evidence supportive of Granger causality from the exchange...

Autores: Craig,   Barbara J.; Pardey,   Philip G.
This abstract describes alternative output aggregates that provide both cross-sectional and temporal comparisons appropriate for the analysis of panel data sets. Several of these multidimensional output indices are constructed using detailed data on agricultural production to illustrate the effects of fixing price weights over time, employing sample average price weights, and choosing between alternative approximations of Divisia indices.

A TEST OF ASSET FIXITY IN SOUTHEASTERN U.S. AGRICULTURE

Autores: Taylor,   Timothy G.; Kalaitzandonakes,   Nicholas G.
A test for static equilibrium developed by Schankerman and Nadiri is used to evaluate the hypothesis that land and capital in aggregate southeastern U.S. agriculture behave as fixed inputs. Empirical results reject the hypothesis that these two inputs are at their long-run equilibrium levels implied by observed prices. Thus, some degree of asset fixity may be concluded.

This report on Pakistan is one of a series of country studies undertaken by the International Trade and Food Security Program are IFPRI on trade and macroeconomic policies. Other studies in this series include research reports on Colombia, Argentina, Nigeria, Zaire, and the Philippines, and collaborative work with the World Bank on this tonic in several other countries in Asia, Africa, and Latin America.  The findings from this research have vividly shown the need to analyze the effects of policy interventions in agriculture in developing countries in an economic-wide framework. There is now an overwhelming body of evidence showing that trade and exchange rate policies have, in most countries, had a far greater impact, generally adverse, on agricultural...

POPULAR INFORMATIONAL PRIORITIES IN AGRICULTURAL EXTENSION
Provedor de dados: 31
Autores: Moffitt,   L. Joe; Christensen,   Robert L.; Fleming,   Kent D.
Due to agriculture's increasingly complex technical and economic environment, the diversity of information required for competitive and profitable farming is growing as never before.  With constant and, in some cases, reduced resources for agricultural programs, Extension must exercise special care in prioritizing informational efforts to best meet farm-client needs and retain an important base of public support.  This paper presents a method of identifying popular informational priorities in Agricultural Extension.  The method is illustrated by application to dairy programming in Massachusetts.

ESTIMATING THE VALUE OF THE 0/92 REDUCED PLANTING ALTERNATIVES OF THE 1985 FARM BILL FOR FARM PROGRAM PATICIPANTS
Provedor de dados: 31
Autores: Thompson,   Troy N.; Knight,   Thomas O.; Boren,   Billy D.
The 50/92 and 0/92 reduced planting alternatives of the 1985 farm bill allow farm program participants more flexibility in making production decisions. Specifically, these provisions relax the incentive to produce inherent in earlier commodity programs that linked deficiency payments directly to harvested acreage. This study examined the value of this additional decision flexibility for crop producers in the Blacklands of Central Texas. The results suggest that the reduced planting alternatives would not be used by, and have no value for risk neutral producers, but have substantial value for risk averse producers who would reduce planted acreage in years when yield expectations are low.

PERSPECTIVES ON COMPETITIVE BIDDING: RETIREMENT OF ENVIRONMENTALLY SENSITIVE FARMLAND
Provedor de dados: 31
Autores: Kozloff,   Keith; Taff,   Steven J.
The USDA has used bidding to enroll land into the Conservation Reserve Program (CRP) and may use similar mechanisms to implement other policy instruments in which some or all agricultural land cropping rights are acquired to protect or increase environmental amenities. Experience with the CRP suggests that current enrollees are being compensated in excess of the lowest payment they would be willing to accept in exchange for loss of cropping rights. While it may be prohibitively expensive to estimate such reservation prices on all potential CRP parcels, it is likewise difficult to design a bidding mechanism that induces landowners to reveal these values.  While the competitive bidding and contingent valuation literatures provide some guidance, the problem...

EVIDENCE FOR A WEATHER PERSISTENCE EFFECT ON THE CORN, WHEAT AND SOYBEAN GROWING SEASON PRICE DYNAMICS
Provedor de dados: 31
Autores: Stevens,   Stanley C.
The growing season weather in the corn, wheat and soybean production areas of the United States is an important determinant of the U.S. supply of these commodities.  The weather and climatology literature strongly suggest that during the summer months there is a degree of persistence in the North American weather patterns.  Given this nonrandom character of weather and given that the corn, wheat and soybean belts are geographically concentrated enough to be dominated by a regional weather phenomenon, their futures markets are hypothesized to reflect this assimilation of nonrandom weather information as nonrandom price fluctuations.  An empirical test of this question is the subject of this paper.

PRODUCT DIFFERENTIATION AND STATE PROMOTION OF FARM PRODUCE: AN ANALYSIS OF THE JERSEY FRESH TOMATO
Provedor de dados: 31
Autores: Adelaja,   Adesoji O.; Brumfield,   Robin G.; Lininger,   Kimberly.
Product differentiation, a prerequisite for successful state promotion of state branded farm products, may be reflected by differences in the own-price, cross-price and income elasticties of demand between a state's brand and other products. This paper tests for such differentiation by estimating demand functions for tomatoes available at the retail level in New Jersey. The "Jersey Fresh" brand is shown to have higher own-price and income elasticities of demand. It is thus perceived to be of higher quality than others. Consumers are also found to be origin biased. Promotion based on the Jersey Fresh's unique attributes and on encouraging further origin bias may have a good chance of success.

Over the last ten years, international donors and African governments have singled out  “inappropriate policies” as a major factor influencing the poor performance of the agricultural  sector and the chronic problem of human hunger. Faced with increasing budget deficits, declining  export earnings, and diminishing access to sources of capital, African governments, as a  condition for receiving debt relief, have been compelled to implement macroeconomic and sectoral  policy reforms - structural adjustments - aimed at rectifying the disincentive policies and  improving the external and domestic public accounts. The reorientation of reforms in the  agricultural sector has centered on improving agricultural incentives through liberalization of  input and...

The lead-lag relationships present in the regional price discovery process are important indicators of market performance. Differences across markets in the speed of adjustment to evolving information may have implications for pricing efficiency within these markets. This study estimates intertemporal price relationships among 11 regional slaughter cattle markets. Larger volume markets, located in the major cattle feeding regions, were the dominant price discovery locations. Price adjustments across markets were complete in one to two weeks in the large volume markets located relatively close to each other and in two to three weeks in the more remote, smaller volume markets.

GROUNDWATER CONTAMINATION AND THE MANAGEMENT OF A CONJUNCTIVE GROUND AND SURFACE WATER IRRIGATION SYSTEM
Provedor de dados: 31
Autores: Tsur,   Yacov.
Irrigation water (including rainfall) that infiltrates the subsurface carries salts, pesticide and fertilizer residues, and other trace elements, thus causing a contamination of aquifers and soils. A similar situation occurs when irrigating with saline groundwater (aquifers containing saline water often are found in arid and semi-arid regions, where agricultural production depends critically on groundwater irrigation). Evaporation of the irrigation water increases salt concentration, causing salinization of soils and aquifers. Although not immediately noticeable, these quality deterioration processes will have long-term effects and therefore require careful management. The paper describes a general framework for the intertemporal management of a...

ANALYSIS OF DRY BEAN PRICE BEHAVIOR IN BURUNDI
Provedor de dados: 31
Autores: Ndarusigiye,   Mevin.
Dry bean production and price statistics for Burundi from 1972 to 1987 indicate significant year-to-year (bean production) and monthly (bean prices) fluctuations.  These fluctuations are influenced by, among other things, climatic conditions, unpredictable markets, government policy, and phytopathological factors.  The objective of the study is to analyze the behavior of dry bean production in Burundi under uncertain prices and assess the degree of uncertainty for the period 1972-1987.  The hypotheses are that dry bean prices in Burundi are uncertain, and that annual dry bean production per capita has been falling because of dry bean price uncertainty.  Two types of regressions models, one with average annual data and another with monthly real price data,...

Aid and Australian Aid Policy
Provedor de dados: 31
Autores: Bhattacharya,   Debesh.
Few issues of economic development arouse such deep emotions or controversies as the role of the foreign sector. Most orthodox economists believe that foreign aid, investment, technology and transnational corporations (TNC) are important contributory factors to economic development. On the other hand, the neo-Marxist paradigm suggests that the present system revolving around the foreign sector represents the continuation of domination over the developing by developed countries. Foreign aid, investment, technology and TNC are regarded as tools of neo-imperialism, the devices by which developed countries continue to retain control over the economies of the ex -colonies. The role of foreign aid in economic development is also criticised by some extreme right...

This report describes relationships between major farm characteristics and co-op use and membership. Analyses were based on multivariate logit regression. Statistically significant relationships were found between farm size and farm location and co-op use but relationships varied greatly by farm type and type of use activity. No statistically significant relationship was found between co-op use and operator age. Statistically significant relationships were found between co-op membership and farm size, operator age, and farm location. These relationships varied also by farm type.

UNDERWRITING ASSISTANCE TO THE AUSTRALIAN WHEAT INDUSTRY - AN APPLICATION OF OPTION PRICING THEORY
Provedor de dados: 31
Autores: Bardsley,   Peter; Cashin,   Paul.
For the ten crop seasons 1979-80 to 1988-89, returns to producers in the Australian wheat industry were underwritten by a government-guaranteed price floor. Similar schemes operate in other rural industries (dairy, apples and pears, dried fruits). Although the underwriting provisions have only been triggered once (in the 1986-87 season), the provision of this scheme has acted to reduce the risk normally associated with returns to producers of wheat in all years of its operation. This reduction in risk has been granted free-of-charge by the Commonwealth Government.  The guaranteed price can be viewed as a put option taken out by the Government on behalf of growers - it gives growers the option to sell to the Australian Wheat Board at this floor price. The...

Assessing the Effectiveness of Farm Supply Cooperatives: A Comparison of Farmer and Manager Viewpoints
Provedor de dados: 31
Autores: Burt,   Lawrence A.; Wirth,   Myron E.
This paper reports the results of a survey of attitudes of commercial farmers and supply cooperative managers about agricultural supply cooperatives. Cooperative managers and farmers frequently made significantly different responses to questionnaire statements. With a few expectations, farm size and farmer age did not appear to influence perceptions about supply cooperatives. Whether a farmer was a cooperative member was important in some cases. Lower prices in lieu of easy credit and patronage refunds were found to be acceptable to farmers, but not at the expense of good service. Managers placed great importance on member loyalty to the supply cooperative without regard to price consideration.

HEDGING RISK FOR FEEDER CATTLE WITH A TRADITIONAL HEDGE COMPARED TO A RATIO HEDGE
Provedor de dados: 31
Autores: Elam,   Emmett W.; Davis,   James.
This paper compares hedging risk for various weights of feeder cattle hedged with a traditional cross hedge and a ratio cross hedge. A traditional hedge calls for the purchase/sale of one pound of futures for each pound of cash feeder cattle. By contrast, a ratio hedge requires estimation of a hedge ratio to determine the number of pounds of futures needed to hedge one pound of cash feeder cattle. Hedge ratios were found to be larger than 1.0 for light-weight feeder cattle. By using the estimated hedge ratios, it was shown that hedging risk could be reduced 20-50 percent compared to that achieved by using a hedge ratio of 1.0.

A dynamic model of oligopoly in the coffee export market
Provedor de dados: 31
Autores: Karp,   Larry S.; Perloff,   Jeffrey M.
A linear-quadratic, dynamic feedback oligopoly model that nests various market structures is used to estimate the degree of competitiveness and the adjustment paths of the two largest coffee exporters, Brazil and Colombia. Their estimated behavior is relatively competitive. This subgame perfect dynamic model is-compared to a standard static oligopoly model and the open-loop model (the dynamic generalization of the standard static model). Both classical and Bayesian tests of open-loop and feedback dynamic models are reported.

Autores: Peters,   Steven E.; Janke,   Rhonda R.; Johnson,   Dale M.; Hanson,   James C.
A long-term whole-farm analysis compared conventional and low-input farming systems.  Data from a nine-year agronomic study at the Rodale Research Farm, Kutztown, Pennsylvania, were used to analyze profitability, liquidity, solvency, and risk on a representative commercial grain farm.  Conventional and low-input farms participating in government programs are the most profitable scenarios, followed by conventional and low-input farms not participating in government programs.  All farms increased their net worth.  The low-input approach is advantageous for risk-averse farmers using a safety-first criterion.

TARGET MARKETS FOR RETAIL OUTLETS OF LANDSCAPE PLANTS
Provedor de dados: 31
Autores: Turner,   Steven C.; Dorfman,   Jeffrey H.; Fletcher,   Stanley M.
Merchandisers of landscape plants can increase the effectiveness of their marketing strategies by identifying target markets. Using a full information maximum likelihood tobit procedure on a system of three equations, target markets for different types of retail outlets in Georgia were identified. The results lend support and empirical evidence to the premise that different retail outlet types have different target markets and thus should develop different market strategies. The estimated target markets are identified and possible marketing strategies suitable for each type of retail outlet are suggested.

The methodology of LaFrance and Hanemann for analysing the structure of incomplete demand systems is applied to models that are linear or logarithmic in quantities, prices and/or income. The structure of each model is presented when the implications of consumer choice theory are satisfied. The usefulness of the approach is illustrated. It is shown that considerable prior information is obtained from the theory of consumer choice when it is applied to this set of functional forms for demand equations.

The relationship between the degree of competitive market pressure and the rate of productivity growth is empirically investigated with a case study of the Florida fresh winter vegetable industry. The results indicate that crops which faced considerable competitive pressure exhibited significant productivity growth while the crops that faced minimal competitive pressure generally exhibited little growth in productivity. Thus, the hypothesis that competitive pressure is positively related to productivity growth is supported.

This research reports the findings of focus group interviews which explored potato buying motives and preferences for russet, red skinned and round white potatoes among selected Northeastern consumers.  The results indicate that the group members perceived all russets as "Idaho" potatoes, associated the red potatoes with gourmet meals, and viewed the round whites as generic potatoes, unsuitable for company meals.  However, participants identified round whites as their personal favorite and as the kind they purchased most often.

This study analyzed consumer response to potatoes tested for pesticide residues. These potatoes were packed in five pound bags and priced at three different levels in participating supermarkets. Even when sold at identical prices, consumers continued to favor the traditional round white over the reside-tested potatoes. However, sales of residue-tested were equal at all three price levels, indicating little price resistance among consumers interested in this type of product.

Autores: McKinnell,   Cathy S.; Kahl,   Kandice H.; Curtis,   Charles E., Jr.
Risk-efficient portfolios from a subset of marketing strategies were identified using Target-MOTAD. Portfolios were generated for Illinois, Arkansas, and South Carolina to determine whether regional price and yield characteristics affected the optimal marketing strategy selection during 1972-1985. The results support previous conclusions that the risk borne when following a combination of marketing strategies was less than the risk of any single marketing strategy examined. The results also show that the marketing strategies representing efficient risk-return combinations for a producer in one region were different from the efficient risk-return combinations for a producer in another region. Therefore, generic marketing advice would have produced results...

Autores: Fischer,   Dieter F.; Craig,   William L.; Ashby,   B. Hunt.
In-transit vibration damage to grapes and strawberries results in reduced quality for the consumer and reduced profits for the produce industry.  To solve this problem, the first step is to determine which vibrational frequencies are causing the damage.  In various tests, grapes and strawberries were subjected to different frequencies at constant force levels.  The effects of the vibration treatments were evaluated on the basis of grading, color analysis, firmness, respiration rate and ethylene production rate.  The critical frequency was found to lie between 7.5 and 10 Hertz for both commodities.  Color change and respiration rate were shown to be good indicators of damage in grapes.  Strawberries did not show a significant effect due to color.  Firmness...

Product attributes that determine nursery-stock sales from wholesalers to retail garden centers and landscapers were studied.  Conjoint analysis was used to obtain data on buyer preferences.  The data were analyzed using ordinary least squares and logit procedures to determine the attributes that are preferred by buyers.  It was determined that good- to excellent-quality stock, offerings with a full line of additional plants, taller plants, and cash discounts are desirable attributes.  Quality is the dominant attribute affecting preferences.  Packaging the preferred attributes together significantly increases the probability of a plant being purchased by buyers.

Almost all applications of the Travel-Cost-Method demand function which include site quality variable(s) are multisite models. The results of this study serve as a note of warning that using the demand equation derived from multisite cross-sectional data to perform a benefit-cost analysis of changes in quality at a single site may not accurately predict the resulting change in the number of trips to that site. In this situation, estimates of the benefits of quality improvements may be unreliable.

This paper employs the dual approach to trace the impact of public policy instruments upon the operational and financial performance of U.S. dairy cooperatives.  A restricted profit function is applied to the Operations and Finance Statements for years 1980-1988 of thirty major dairy cooperatives.  The data set for this study is provided by the Agricultural Cooperatives Service, USDA.  A specification search such  as described in Mountain and Hsaio (1989) is conducted to ensure the most appropriate fit for the data provided.  From the estimated parameters, output supply and factor demand elasticities will be obtained by way of well-known functional relationships.  From these elasticities, the short-run effect of any change in Federal Marketing Order prices...

Concern has been voiced that U.S. Department of Agriculture (UDSA) Farm Costs and Returns Surveys are used for a wide variety of policy analyses but produce questionable estimates. USDA-developed crop and livestock cost and return estimates for New Mexico and other selected states are compared to estimates developed by state universities. Major differences exist, most important of which relate to the ability of the survey respondent to answer the questions posed. Regardless of the cause of the differences, closer cooperation between the USDA and state universities clearly is needed to develop consistent estimates.

ECONOMETRIC ANALYSIS OF FARMER PARTICIPATION IN THE DAIRY TERMINATION PROGRAM IN NORTH CAROLINA AND VIRGINIA
Provedor de dados: 31
Autores: Gale,   H. Frederick, Jr.
Farm-level data are used to estimate equations explaining the probability of bidding and the level of the bid for the 1986 Dairy Termination Program. Participation was attractive to older farmers, to those who were not planning to transfer the farm to a family member, to less experienced farmers, and to those using less sophisticated management techniques. Schooling, off-farm work, and nonfarm experience did not have significant effects. The participation pattern suggests that the long-term effects of the program on milk supply are small.

RETAIL FOOD STORE INVENTORY BEHAVIOR

Autores: Miller,   Stephen E.
A stock-adjustment model is applied to monthly retail food store inventory data from 1968 through 1988. Estimates of the speed-of-adjustment coefficient (.34 to .75) are higher than estimates from previous research, indicating that periods of inventory disequilibrium in food retailing are short-lived. The results indicate that inventories are insensitive to financial carrying costs. The hypothesis that parameters of the model are constant over the sample period cannot be rejected, indicating that changes in food retailing (e.g., electronic scanning and diversification of product mixes) have not affected inventory behavior.

Autores: Freeze,   Brian S.; Hironaka,   R.
A maximum profit linear programming feedlot model is presented to determine if diet combinations of moderate amounts of hay and grain are economically optimal when time (length of the feeding period), form of hay (long versus cubed alfalfa), and carcass quality are considered.  While the experiment did not include concentrate-to-hay ratios as high as commercial feedlot use, the results show that highest concentrate diets are economical in all stages of the finishing program, except that when time and carcass grade effects are considered and hay-to-concentrate price ratios are at historical lows, a switch is made for the last 90 kg of grain to diets somewhat above 50% hay.

SCALE NEUTRALITY OF BOVINE SOMATOTROPIN: EX ANTE EVIDENCE FROM THE SOUTHEAST
Provedor de dados: 31
Autores: Kinnucan,   Henry W.; Hatch,   L. Upton; Molnar,   Joseph J.; Venkateswaran,   Meenakshi.
Bovine somatotropin (BST), a new technology capable of enhancing a cow's ability to produce milk by 7-23 percent, is expected to be available for commercial use soon. Ex ante survey procedures are used to determine the potential effect of BST on the size distribution of dairy farms in the Southeast. Results of logit analysis indicate a positive link between farm size and (1) farmers' knowledge of BST and (2) intentions to adopt early, suggesting BST will not be scale neutral. An estimated "price elasticity" of -1.8 to -2.1 indicates an elastic demand for the input. Price, therefore, may be an effective instrument for attenuating the scale bias.

ORGANIC FOOD ADOPTION DECISIONS BY NEW MEXICO GROCERIES
Provedor de dados: 31
Autores: Ireland,   Polly E.; Falk,   Constance L.
Sales for organically grown foods, particularly organic fresh produce are increasing. This study focuses on the characteristics of grocery stores in New Mexico who sell or intend to sell organic foods. The results suggest most grocery stores do not carry organic foods because of the low availability and perceived consumer demand. However, stores that sell organic foods reported consumer demand prompted them to carry organic foods. The results can provide information for grocery stores to further understand problems and benefits associated with adopting organic foods.

CONJOINT ANALYSIS OF DEER HUNTING
Provedor de dados: 31
Autores: MacKenzie,   John.
This paper develops a logit-based conjoint analysis of willingness to pay for individual attributes of deer-hunting trips.  Since deer-hunting success is uncertain, willingness to pay for enhanced likelihood of bagging a deer, rather than for certain success, is evaluated.  Implicit costs of recreational travel time are also evaluated from hypothetical trade-offs between travel time and trip expenditures.  The valuation of travel time derived here appears to reflect more the opportunity cost of foregone hunting than the opportunity cost of foregone work.  This implies that travel-cost analyses of recreational demand, which impute costs of recreational travel solely from wage data, can yield biased valuations of recreational amenities.

Binary logit and bivariate probit models were used to investigate the investment behavior of farmers relative to two energy-conserving assets, heat-recovery systems and precoolers.  The bivariate probit procedure was useful in correcting for self-selectivity bias.  Holdout samples and cross-validation procedures were used to develop true model statistics.  Farm size, educational level of the operator, and the type of milking system in use were the important factors influencing investment behavior.

A procedure using linear programming and Bayesian analysis for incorporating risks associated with cattle prices and forage yields was developed for maximizing net ranch income in the Southern Plains of Texas. Risk-efficient production/marketing (buy/sell) strategies included strategies which assume normal and low cattle prices and low and normal forage production. Only one of the enterprises in the risk-efficient strategies constituted a traditional marketing approach of spring buying and fall selling.

ENVIRONMENTAL HAZARDS OF FARMING: THINKING ABOUT THE MANAGEMENT CHALLENGE
Provedor de dados: 31
Autores: Shabman,   Leonard A.
What an economist argues about managing the hazards of new production technologies depends on that individual's beliefs about the scientific credibility of assessed risk of new technologies, about the meaning of voluntary risk and compensations, and about the meaning of "progress" and "nature." None of these beliefs is derived from the core of the economics discipline. Indeed, the economist's arguments often rest not on economic considerations, but on these matters of belief that are established outside the discipline.

Fifty Years of Farm Management in Australia: Survey and Review
Provedor de dados: 31
Autores: Malcolm,   Bill.
Fifty years of Australian academic literature about farm management is surveyed and reviewed chronologically and methodologically. Farm management started as a field of academic inquiry during the 1940s, and at the end of the first decade most of the major emphases which were to predominate over the ensuing decades had made their debut in the literature. Major emphases over the fifty years have been records and accounts, production economic thinking, linear programming, decision theory and systems simulation approaches. Overtime came increasing doubt about the usefulness of each of these emphases, and in the 1980s journal writings about farm management declined greatly. Much academic work about farm management during the past fifty years lacked relevance...

PRODUCT CHARACTERISTICS AND ARBITRAGE IN THE AUSTRALIAN AND NEW ZEALAND WOOL MARKETS
Provedor de dados: 31
Autores: Angel,   C.; Beare,   Stephen; Zwart,   A.C.
The physical characteristics of wool are important determinants of its spinning properties, yarn quality and end use. The degree to which wools from different countries of origin may be substituted has important implications for the domestic marketing policies of Australia and New Zealand. The hypothesis examined in this paper is that the differences in wool prices can be explained by differences in the physical characteristics of the wool and that objective measures of these characteristics allow for effective arbitrage between these markets. The alternative hypothesis is that premiums or discounts exist owing to country of origin. A hedonic price analysis was conducted on wool prices in Australia and New Zealand using a balanced sample of sale lot data...

MARKETING RESPONSES TO CHANGING CONSUMER PREFERENCES IN THE FRESH BEEF INDUSTRY
Provedor de dados: 31
Autores: Procopio,   Mary Elizabeth.
The fresh meat industry is changing the way it markets its products. The decline in red meat consumption that has resulted from greater consumer concerns about the "healthfulness" of red meat, coupled with changes in consumer lifestyles emphasizing a need for convenience is contributing to the diminishment of "commodity selling" in favor of a true "marketing" approach (Pierson and Allen, 1986). In a traditional industry such as meats, the shift from a commodity-selling perspective (i.e., selling of homogeneous goods) to a marketing (i.e., selling of homogeneous goods) to a marketing (i.e., marketing of differentiated goods) perspective is a slow transition. The fresh beef industry is moving toward the adoption of this contemporary food marketing strategy...

A set of rigorous diagnostic techniques is used to evaluate the forecasting performance of five multivariate time-series models for the U.S. cattle sector. The root-mean-squared-error criterion along with an evaluation of the rankings of forecast errors reveals that the Bayesian vector autoregression (BVAR) and the unrestricted VAR (UVAR) models generate forecasts which are superior to both a restricted VAR (RVAR) and a vector autoregressive moving-average (VARMA) model. Two methods for calculating a test evaluating the ability to forecast directional changes are implemented. The BVAR models and the UVAR model unambiguously outperform the VARMA model in the forecasting directional change

The substantial investment in models of international food markets immediately prior to and during the Uruguay Round of international trade negotiations has been a mixed blessing so far as the prospects for reform are concerned. At worst, results from these models have mislead the negotiations, first because they have served the losers from reform better than the gainers and second, because they have tended not to address a primary concern lending domestic political support to food market interventions, namely the avoidance of risks borne of dependence on international markets. The paper reviews some errors which have stemmed from the application of 'standard' but inappropriate models and examines the implications of extending the standard methodology to...

American Agricultural Policy and the 1990 Farm Bill
Provedor de dados: 31

The United States (U.S.) government recently finished its five year ritual of farm legislation. In general, the 1990 Farm Bill, or the Food, Agriculture, Conservation and Trade Act of 1990, extends most of the program features of its predecessor, the Food Security Act of 1985 (FSA). The recent bill continues a 57 year old tradition represented by loan rates, target prices, deficiency payments, base acres and yields, quotas, production controls, marketing loans, and other devices which support prices and income in return for retiring acres. However, the bill introduces several features that move it incrementally in the direction of "decoupling", and continues the trend set in 1985 of adding new environmental restrictions on farm practices.

Autores: Rwamasirabo,   Serge.
This study is uniquely structured to assess the potential for future development of the Rwandan goat industry based on a thorough empirical analysis of how farm households of many different types participate in, and depend on, this pervasive industry. Data from the 1984 National Agricultural Survey in Rwanda and the 1989 follow-on survey permit us to highlight recent trends in goat (and other livestock) production in Rwanda, and to assess the degree to which variations in goat production are linked to other household and farm characteristics. Findings show that farmers are adapting to population pressure by shifting away from the production of cattle in favor of small ruminant production. Declining farm size, low start-up costs and relatively low mortality...

Consumers' willingness to pay for cowpea products was analyzed by a multi-ordered response model.

Thus, akara products, made from cowpea paste, have potential for extending the utilization of cowpeas.

Cooperatives' Role in the Artificial Insemination Industry
Provedor de dados: 31
Autores: Hogeland,   Julie A.
The artificial insemination industry provides breeding products and services for both dairy and beef cattle. Two-thirds of the industry is organized as producer-owned cooperatives. The industry has been so highly successful in meeting the needs of producers for a high-quality reliable product that the United States is the world's leading producer and exporter of bull semen. Yet, more bulls (and consequently more cooperatives) are available than are technically needed for genetic variation and breeding requirements. The result of such product proliferation is higher semen prices and excessive costs for inventory, distribution, and marketing. To maintain their prominent role in the industry, the 22 cooperatives need to consolidate to streamline the...

Agricultural economists in both the United States and Canada have been trying to answer this complicated question for over 12 years. Although there is no simple answer t researchers generally agree that the "right level" of advertising investment is a function of the promotion program's objective. The actual level of advertising investment in 1987 totaled $490 million in 22 dairyproducing countries. The United States t Canada t Australia t and the United Kingdom have similar levels of promotion investment per unit of milk production ($0.12 to $0.17 per hundredweight). A review of economic studies "indicates commodity advertising investment in the U.S. is probably less than optimum at its current level of around $145 million.

POLICY ANALYSIS IN AN IMPERFECTLY COMPETITIVE MARKET: A CONJECTURAL VARIATIONS MODEL FOR THE FOOD MANUFACTURING INDUSTRY
Provedor de dados: 31
Autores: Maier,   Leopold.
The effects of government policies are analyzed in a conjectural variations model of U.S. food manufacturing. The policy elasticities of the perfectly competitive model are valid predictors of policy effects irrespective of the type of oligopoly. Changes in the degree of competition may alter the magnitude of the policy elasticities.  Keywords: firm behavior, market structure, imperfect competition, conjectural variations model, policy analysis, food manufacturing

CONSUMER ACCEPTANCE OF IRRADIATED FOOD PRODUCTS: AN APPLE MARKETING STUDY
Provedor de dados: 31
Autores: Terry,   Danny E.; Tabor,   Richard L.
This study was exploratory in nature, with emphasis on initial purchases and not repeat purchases or long-term loyalties to either irradiated or non-irradiated produce.  The investigation involved the actual sale of irradiated and non-irradiated apples to consumers.  Limited information about the process was provided, and apples were sold at roadside stands.  Prices for the irradiated apples were varied while the price for the non-irradiated apples was held constant.  Of these 228 West-Central Missouri shoppers, 101 (44%) bought no irradiated apples, 86 (38%) bought only irradiated apples, and 41 (18%) bought some of both types.  Results of probit regressions indicated three significant independent variables.  There was an inverse relationship between the...

Debt-For-Nature Swaps and the Environment in Africa
Provedor de dados: 31
Autores: Kyle,   Steven C.
This paper discusses the use of debt-for-nature swaps as a funding mechanism for environmental expenditures in Sub-Saharan Africa. The pros and cons of such transactions for creditor banks, environmental groups and debtor countries are discussed and evaluated in terms of their ability to address environmental problems prevalent in the region. It is concluded that the usefulness of debt swaps may be limited and that direct donations to developing countries for environmental purposes may often be superior to swap transaction.

THE INFLUENCE OF CONSUMER CONCERNS AND DEMOGRAPHIC FACTORS ON PURCHASING PATTERNS FOR BEEF
Provedor de dados: 31
Autores: Menkhaus,   Dale J.; Pingetzer,   Robert L.; Whipple,   Glen D.; Field,   Ray A.
The results of a cross-tabulation analysis indicate that health-related concerns for roasts, steaks and ground beef are expressed significantly more frequently by survey participants eating less beef as compared to those who report the same amount in beef usage. The results generally suggest that chicken is served more frequently by those eating less beef than by those who have not changed their beef-eating habits or are eating more beef. Expense was identified as a concern for both roasts and steaks. Those eating less beef are typically older than those indicating more or the same beef usage.

Use of Firm Level Agricultural Data Collected and Managed at the State Level for Studying Farm Size Issues
Provedor de dados: 31
Autores: Casler,   George L.
Individual farm financial data are collected in about two dozen states by colleges of agriculture, farm record associations and state vocational-technical school programs. A wide variety of methods are used by the various systems to calculate measures of profitability, making it difficult to make comparisons across states or to use data from several states to study farm size issues. This paper reviews some of the issues related to measuring profitability such as asset valuation, appreciation of assets, depreciation, interest changes, and value of operator and family labor and management. Data from three states are used to relate farm size to profitability. In general, larger farms have higher net returns regardless of the measure of profitability used, but...

The Feudal Society in Today's University
Provedor de dados: 31
Autores: Houck,   James P.
Few institutions puzzle outsiders as much as the modern university. Even insiders may not grasp the primal essence of its life and behavior. The sheer size and diversity of many universities defeats orderly consideration. We adopt crude simplifications or, worse, numbing obfuscation. This is entirely unnecessary. The core of university life can be illuminated clearly through the prism of a rich and beguiling metaphor. This metaphor requires only that we see today's university as a thinly disguised feudal society such as existed in Europe during the 11th or 12th century A.D. In this medieval context, many otherwise baffling modern mysteries in academe become transparent.

RISK AND SUSTAINABLE AGRICULTURE: A TARGET-MOTAD ANALYSIS OF THE 92-YEAR "OLD ROTATION"
Provedor de dados: 31
Autores: Novak,   James L.; Mitchell,   Charles C., Jr.; Crews,   Jerry R.
Target-MOTAD was used to assess the risks and returns of sustainable cotton crop rotations from Auburn University's 92-year "Old Rotation." Study results analyze rotations of continuous cotton, with and without winter legumes; two years of cotton-winter legumes-corn, with and without nitrogen fertilization; and three years of cotton-winter legumes-corn and rye-soybeans double-cropped. Ten years of observations on deviations from target income were used to identify optimal sustainable rotation(s). Study results suggest that diversification in rotations, as well as in crops, results in the least risk for a given level of target income.

EFFECT OF THE 1985 FARM BILL PROVISIONS ON FARMERS' SOIL CONSERVATION DECISIONS
Provedor de dados: 31
Autores: Gillespie,   Jeffrey M.; Hatch,   L. Upton; Duffy,   Patricia A.
Conservation initiatives in the 1985 Farm Bill affected farmers' decisions regarding soil conservation. A farmer survey was conducted and a multiperiod mixed-integer programming model was developed to determine an optimal farm plan with choice of crop-tillage combinations and land retirement. Results indicate that farmers' incentives to reduce soil loss in the Sand Mountain region in Alabama are not substantially affected by provisions of the 1985 Farm Bill. The bid price for the Conservation Reserve Program will have to be considerably higher than 1988 levels to provide an incentive to remove land from production.

Provedor de dados: 31
Autores: Manalo,   Alberto B.
The use of conjoint analysis in assessing consumers' preferences for attributes is demonstrated with the apple as an example.  Conjoint analysis may be used to estimate the importance of attributes and attribute levels through decomposition of consumers' ranking of alternative attribute combinations.  It is shown that conjoint analysis provides results that may not be obtained from a survey where respondents are asked to directly state their assessment of the importance of attributes.

ANALYSIS OF CONSUMER ATTITUDES TOWARD NEW FRIED FOOD PREPARED FROM COWPEA FLOUR
Provedor de dados: 31
Autores: Fletcher,   Stanley M.; McWatters,   Kay H.; Resurreccion,   Anna V.A.
American consumers are exposed to thousands of new food products on supermarket shelves each year.  For new products, such as akara products, it is crucial to determine consumer preferences and buying intentions.  In this study, 346 randomly selected consumers were surveyed to reveal their preference for five akara products prepared from cowpea flour.  Preference data were analyzed through use of a multi-ordered response model.  Model results indicate that socio-demographic factors were weakly linked to explaining consumer preferences while product characteristics were much more important in preference considerations.

IMPERFECT COMPETITION, TRADE POLICY AND PROCESSED AGRICULTURAL PRODUCTS: SOME INITIAL RESULTS
Provedor de dados: 31
Autores: McCorriston,   Steve; Sheldon,   Ian M.
This paper applies some recent developments in international trade theory to processed agricultural product markets.  Theoretical results are derived showing that when such markets are characterized by imperfect competition, there may be a case for government intervention in the form of subsidies and tariffs.  In order to provide some empirical background, a simulation model is used to assess the level of an optimal tariff on U.S. cheese imports.  The implications of this analysis for the liberalization of agricultural trade are also considered.

The use of computable general equilibrium models to assess water policies
Provedor de dados: 31
Autores: Berck,   Peter; Robinson,   Sherman; Goldman,   George E.
This paper discusses basic issues in project analysis and shows how these issues can be resolved in a computable general equilibrium (CGE) framework. The role of border prices and intersectoral linkages is explored. The CGE framework is compared to less comprehensive frameworks, including benefit-cost analysis, input-output models, multi-market models, and models based on social accounting matrices (SAMs). An illustrative CGE model of the southern portion of the San Joaquin Valley is constructed and is used to find the effects of reducing water inputs on aggregate Valley gross domestic product (GDP) and on sectoral output, employment, and land use. The model is also used to determine demand curves for water by the southern portion of the Valley, given...

A TEST OF BAYESIAN LEARNING FROM FARMER TRIALS OF NEW WHEAT VARIETIES
Provedor de dados: 31
Autores: Lindner,   Robert K.; Gibbs,   Melissa.
In this study, elicited estimates of farmers' subjective beliefs about the mean and variance of wheat variety yields were used to test propositions about Bayesian learning developed in the recent literature on innovation adoption. A series of empirical tests of the Bayesian adoption model were conducted using beliefs elicited from farm surveys conducted in 1982, 1983 and 1984. The results of the analysis neither confirm nor reject the Bayesian approach as a model of how farmers revise subjective beliefs, but do raise serious doubts about its realism, and suggest some issues requiring further investigation. Shortcomings in the elicitation techniques are discussed and the assumptions of the Bayesian model are reviewed.

IMPACTS OF ALTERNATIVE TILLAGE, FERTILIZATION, AND HERBICIDE APPLICATION METHODS ON CORN PRODUCTION COSTS AND RETURNS
Provedor de dados: 31
Autores: Olson,   Kent D.; Weber,   Craig.
The impacts on actual corn production costs and returns were analyzed. Tillage, fertilization, and herbicide alternatives are reported. Both stubble and ridge till planting had lower costs per bushel and higher returns per acre than conventional tillage. Banding of fertilizer and, to a lesser extent, manure management had lower costs per bushel and higher returns per acre than broadcast application of fertilizer. Manure applications increased both diesel fuel use and time required per acre. Since corn yields by herbicide application method varied in the same order as the cash rent cost (a proxy for land quality), the differences between application method may be due to both factors. These observations were from one year and a few farms so should be...

THE ECONOMICS OF A STOCK POLLUTANT: ALDICARB ON LONG ISLAND
Provedor de dados: 31
Autores: Conrad,   Jon M.; Olson,   Lars J.
A stock pollutant is a residual waste that can accumulate or degrade over time. Aldicarb was a pesticide used by farmers growing fruit and vegetables. Potato growers on eastern Long Island, New York, used aldicarb from 1975 to 1979 to control the Colorado potato beetle and the golden nematode. In August of 1979 aldicarb residues were detected in well water, and subsequent testing found more than 2,000 wells with concentrations in excess of the New York State health standard of 7 parts per billion (ppb). Aldicarb was banned from use on Long Island after 1979. In this paper we develop a dynamic model of a stock pollutant. The model is calibrated for aldicarb on eastern Long Island and steady-state solutions for static profit-maximizing rate and the...

One of the most uncertain resources for a western beef cattle ranch is the availability of reliable spring forage. The impact on ranch equity position and income variability of investments in crested wheatgrass seedings designed to stabilize spring forage supplies is examined. Expected ending net worth under stochastic forage production and cattle prices is maximized subject to secondary safety-first objectives. Seedings increase expected ending net worth and increase annual net ranch incomes after plant establishment.

Over the past several years IFPRI has undertaken research on the production, consumption, and nutrition effects of agricultural commercialization in The Gambia, Guatemala, Kenya, the Philippines, and Rwanda. While it is widely recognized that the commercialization of agriculture is essential to overall economic development, various rural population groups adapt differently to the process of commercialization, depending on the resources available to them, economic and social conditions, and government policies. Many households benefit in the form of higher incomes; others may suffer a decline in income. A particular concern of policymakers has been the effect of commercialization on nutrition. The purpose of these studies has been to analyze the process of...

GENERALIZED STOCHASTIC DOMINANCE: AN EMPIRICAL EXAMINATION
Provedor de dados: 31
Autores: McCarl,   Bruce A.
Use of generalized stochastic dominance (GSD) requires one to place lower and upper bounds on the risk aversion coefficient. This study showed that breakeven risk aversion coefficients found assuming the exponential utility function delineate the places where GSD preferences switch between prospects. However, between these break points, multiple, overlapping GSD intervals can be found. Consequently, when one does not have risk aversion coefficient information, discovery of breakeven coefficients instead of GSD use is recommended. The investigation also showed GSD results are insensitive to wealth and data scaling but are sensitive to rounding.

A linear-quadratic, dynamic feedback oligopoly model that nests various market structures is used to estimate the degree of competitiveness and the adjustment paths of the two largest coffee exporters, Brazil and Colombia. Their estimated behavior is relatively competitive. This subgame perfect dynamic model is-compared to a standard static oligopoly model and the open-loop model (the dynamic generalization of the standard static model). Both classical and Bayesian tests of open-loop and feedback dynamic models are reported.

COMPARATIVE FORECAST ACCURACY IN THE NEW SOUTH WALES PRIME LAMB MARKET
Provedor de dados: 31
Autores: Vere,   David T.; Griffith,   Garry R.
The market for Australian prime lamb is characterised by high production seasonality and a highly competitive retail demand. Because these factors often translate into substantial market variability, regular forecasts of supply and demand are important requirements of lamb market participants. There has been some forecasting activity in the state and national lamb markets but it has been a somewhat controversial activity. This paper assesses the comparative forecast accuracy of a range of methods in the New South Wales lamb market. The results indicate that no single method is clearly superior in all situations and the greatest scope for improving forecast accuracy in the New South Wales lamb market is through the use of combined econometric and naive...

ANALYSIS OF FACTORS AFFECTING COW AUCTION PRICE DIFFERENTIALS
Provedor de dados: 31
Autores: Mintert,   James R.; Blair,   Joanne; Schroeder,   Ted C.; Brazle,   Frank.
Data from Kansas cattle auctions were analyzed to estimate the impact a wide variety of physical characteristics had upon cow prices. Weight, lot size, health, pregnancy, grade, dressing percent, breed, time of sale, and market location were important factors affecting the differences in cow prices across lots on a given day. Results suggest that producers interested in maximizing the price they receive for their cows should market healthy cows in desirable lot sizes at higher dressing percentages.

A SEQUENTIAL CHOICE MODEL OF RECREATION BEHAVIOR
Provedor de dados: 31
Autores: Adamowicz,   Wiktor L.; Jennings,   Sarah; Coyne,   Alison.
The travel cost model is the standard model used in the recreation demand literature. This model assumes that the decision on the number of trips to a particular site in a given period (a season, for example) is determined at the beginning of the period. For certain types of recreation activity, this decision may be more appropriately modeled as a sequential process, in which the decision of whether or not to take each additional trip is made after previous trips have occurred.  This decision is dependent on the realization of random variables on previous trips as well as travel costs.  A model is developed in which the choice of a discrete number of sequentially chosen trips to a given site is specified as function of site-specific variables and variables...

ANALYZING FRESH VEGETABLE CONSUMPTION FROM HOUSEHOLD SURVEY DATA
Provedor de dados: 31
Autores: Reynolds,   Anderson.
To analyze fresh vegetable consumption using household survey data, the tobit model and a more flexible parameterization to the tobit model - the "double hurdle" model - were considered. Based on the likelihood ratio test, the tobit model was rejected against the "double hurdle" specification. Moreover, the results suggest that the tobit model underestimated the impact of the explanatory variables on fresh vegetable expenditures. Other results indicate that total food expenditures (proxy for income), age, household composition, sex, race, marital status, urbanization, region, and seasonality are all important determinants of fresh vegetable expenditures.

The Elicitation of Subjective Probabilities with Applications in Agricultural Economics
Provedor de dados: 31
Autores: Norris,   Patricia E.; Kramer,   Randall A.
Probability judgements are important components of decision making under uncertainty. In particular, economic decisions can be aided by assuring more accurate assessment of probabilities and more realistic modelling of economic problems through the inclusion of subjective probabilities. The purpose of this paper is to describe the techniques which can be used to elicit subjective probabilities and the ways in which these techniques can be incorporated into agricultural economics research. The review draws from the statistics, psychology, management, operations research, meteorology and economics literature.

ESTIMATING THE PROFITABILITY OF POOL COOPERATIVES
Provedor de dados: 31
Autores: Lerman,   Zvi; Parliament,   Claudia.
Profitability measures are omitted from performance analyses of marketing pool cooperatives that do not include raw products in their reported costs.  A procedure to estimate the profitability of these cooperatives is proposed, converting net proceeds to a figure comparable to standard net profit or net margin.  The median ROE calculated using the proposed adjustment was found to be significantly different from the median ROE of "net-margin-reporting" pools over the period 1971-1987. Application of this procedure will allow pool cooperatives to compare their profitability to other cooperatives and investor-owned firms.

DETERMINANTS OF IRRIGATION TECHNOLOGY CHOICE
Provedor de dados: 31
Autores: Negri,   Donald H.; Brooks,   Douglas H.
Two discrete choice models relate the probability of choosing two water-saving irrigation technologies - —sprinkler and tailwater recovery pits- —to the underlying physical and economic attributes of the farming using a national cross section of farm level data. The results show that small farm size, high water or labor costs, and soils with low water-holding capacity increase the likelihood of adopting sprinkler irrigation. For gravity irrigators, large farms, high water costs, and solid with high water-holding capacity increase the probability of recirculating field runoff. In both models soil characteristics and, to a lesser extent, climate dominate the selection probabilities.

EVALUATION OF SELECTED FRESH VEGETABLE TERMINAL MARKETS: A STOCHASTIC DOMINANCE APPROACH
Provedor de dados: 31
Autores: Hinson,   Roger A.; Lee,   John G.; Huh,   Mooyul.
Vegetable production can offer a high-valued cash crop alternative. While returns may be high, vegetables are perceived to have more risk than conventional row crops. This study used stochastic dominance analysis to evaluate terminal market price risk for four vegetable crops across five market locations. Results from the analysis identify differences in efficient market selection depending on the form which price risk follows. While vegetables as a whole are considered risky, substantial differences in the type of terminal market price variability existed between the commodities.

A VARIABLE PRICE SUPPORT FARM PROGRAM: A TRANSITION TOOL TO A FREE MARKET
Provedor de dados: 31
Autores: Huang,   Wen-Yuan; Hyberg,   Bengt; Segarra,   Eduardo.
This paper analyzes a variable price support program (VPS) as an alternative to the current farm income support program. The VPS program can control U.S. agricultural production while protecting income of small farmers. The VPS is designed to alter farm level production decisions by reducing commodity support prices for each additional unit of production produced. This will serve to discourage excess aggregate production. The VPS program can be a mechanism to stabilize income of efficient small farms during the transition from the current farm programs to a free market environment. An illustrative study is used to target government program benefits to various farm-size groups.

WELFARE IMPLICATIONS OF THE WOOL ACT

Autores: Whipple,   Glen D.; Menkhaus,   Dale J.
A model of the U.S. sheep industry is estimated and simulated to determine the impact of the wool incentive program on actors in U.S. sheep product markets.  The simulation analysis indicates that U.S. sheep producers and lamb and wool consumers are the program’s gainers while lamb and wool exporters and taxpayers are its losers. Net societal losses averaged $26.4 million per year during the 1980-85 period, considering U.S. as well as exporter interests. This loss is about 2.5% of average U.S. consumer expenditures on lamb and wool over the period.

THE MODERN SEED-FERTILISER TECHNOLOGY AND ADOPTION OF LABOUR-SAVING TECHNOLOGIES: THE PHILIPPINE CASE
Provedor de dados: 31
Autores: David,   Cristina C.; Otsuka,   Keijiro.
While intervillage differences in the adoption of modern rice varieties (MVs) are explained mainly by environmental variables, rather than by socioeconomic factors, relative factor prices are the most important determinants of the adoption oflabour-saving technologies. There is no indication that MV adoption is correlated with the adoption of tractors and threshers as well as cropping intensities. Adoption of direct seeding, however, appears to be associated with MV adoption.

COMMODITY PROGRAM SLIPPAGE RATES FOR CORN AND WHEAT
Provedor de dados: 31
Autores: Love,   H. Alan; Foster,   William E.
Slippage rates for corn and wheat are estimated using a simultaneous system explaining per-acre yields, input usage, technical change, and levels of participation in government programs. Soybeans are included due to cross-compliance requirements and because they substitute for corn in production. Slippage rates for wheat are in the range of 29-37% and for corn in the range of 48-58%. The results imply that efficient design of commodity programs must account for the slippage of aggregate yields due to changes in land quality and the use of constrained resources over fewer acres.

ACCOUNTING FOR THE IMPORTANCE OF NONFARM INCOME ON FARM FAMILY INCOME INEQUALITY IN NEW YORK
Provedor de dados: 31
Autores: Boisvert,   Richard N.; Ranney,   Christine K.
As the proportion of farm family income due to nonfarm sources continues to grow nationally, it is important to understand how farm families in various regions or states are affected.  This paper develops a better understanding of the contribution of income from nonfarm sources to the level and distribution of income among farm families in New York.  In analyzing income distribution, the Gini ratio is decomposed to determine the effects of  marginal changes in income by source to overall inequality.  The results are compared with the simulated changes in income inequality due to changes in income by source as measured by an "adjusted" Gini ratio which accounts specifically for negative farm incomes.  Differences in the policy implications from both...

Agricultural Competitiveness and Environmental Quality: What Mix of Policies Will Accomplish Both Goals?
Provedor de dados: 31
Autores: Creason,   Jared R.; Runge,   C. Ford.
Agricultural competitiveness and environmental quality are increasingly consensus objectives for American agriculture. Yet the institutional interests undergirding agricultural policy are often at odds with those promoting improved environmental quality. This paper examines ways in which institutional reforms can improve both agricultural competitiveness and the environment. Farmers, like other business managers, make decisions based on information received from markets and other sources. This report shows how farm management as an activity responds to signals from commodity markets, federal agricultural policies, federal and state environmental regulations, and private sector and university extension recommendations. These individual signals are examined...

Factors Associated with the Selection of Cooperative vs. Proprietary Handlers of Milk in Tennessee
Provedor de dados: 31
Autores: Jensen,   Kimberly L.
Factors that influenced the decision by dairy farmers to select cooperatives milk handlers versus proprietary handlers were examined. In a 1989 survey, Tennessee dairy farmers were asked to indicate reasons that influenced their choice of milk handler, such as better price, an assured market, and better service. Characteristics of the dairy farmers were then compared between those who selected a specific reason and those who did not. Better service and an assured market were the most often cited reasons by cooperative members, and higher price and lower deductions were cited more often by nonmembers. Farmers who cited price as a reason tended to have larger dairy farms, be less diversified, and more indebted than those who did not cite price as a reason....

A control model of the U.S. dairy sector was constructed to determine optimal policy when bovine somatotropin is released. Social welfare defined as consumer plus producer surplus minus adjustment and net government costs was maximized. Control variables were the milk support price and government purchases of cows. Compared to previous simulation research where government policy and adoption were modeled exogenously, the results show that policy not overly disruptive to the dairy sector is possible.

An Analysis of Consolidation for the Farm Supply Sector
Provedor de dados: 31
Autores: Taylor,   William J.; Vogler,   Larry L.
Changing farm numbers and a changing farm supply industry have prompted many regional cooperatives to consider consolidation of local branches as a means of remaining profitable. A behavioral model has been developed that would permit management of regional cooperatives to consider consolidation of product lines or complete branch closures. This model was used in an empirical analysis of a regional cooperative with an overinvestment in capital assets in its local branches. The results indicated that product line consolidation of major products would result in a greater savings than store closure.

CITRUS EXPORT MARKET DEVELOPMENT AND MAINTENANCE
Provedor de dados: 31
Autores: Fairchild,   Gary F.; Lee,   Jonq-Ying.
The marketing of agricultural commodities and food products has assumed an international dimension over the past two decades. Increased funding of export development programs by the federal government and commodity organizations suggest the need for improved understanding of U.S. export development programs and of the issues associated with export market development and maintenance. The lesson to be learned from the citrus industry experience is that unless the commodity or food product being promoted can be differentiated from other competitive products, or unless the product is priced lower than competitive products, or unless the product is priced lower than competitive products, the long-run effectiveness of export promotion programs will be limited.

Conclusions include: (a) flexible cropping increases net discounted returns and substantially reduced soil erosion compared to the predominant crop rotation; (b) chemical fallow is a viable alternative to tillage fallow but only when topsoil already has been eroded substantially; and (c) an increase in the discount rate is soil conserving, since it causes producers to plant more often rather than fallow.

INFORMATION VALUE IN WEED MANAGEMENT
Provedor de dados: 31
Autores: Gillmeister,   William J.; Moffitt,   L. Joe; Bhowmik,   Prasanta C.; Allen,   P. Geoffrey.
Use of the economic threshold to improve the efficiency of preemergent-herbicide treatment decisions is limited by a lack of weed information.  An economic model for assessing the expected value of weed information needed to implement a threshold decision rule is developed.  Empirical results suggest that early season weed information can have value in cabbage weed management in Massachusetts.

A HEDONIC ANALYSIS OF PRIVATE HUNTING LAND ATTRIBUTES USING AN ALTERNATIVE FUNCTIONAL FORM
Provedor de dados: 31
Autores: Messonnier,   Mark L.; Luzar,   E. Jane.
A hedonic framework is used to analyze selected attributes of Louisiana deer hunting leases that are hypothesized to be significant contributors to lease value. The flexible Box-Cox functional form is used in contrast to the often utilized linear regression specification. Additionally, the hypothesis of regional differences in slope coefficients of lease attributes is addressed. Results indicate that hunters in the two analyzed regions value lease attributes and services differently.

AN ANALYSIS OF THE COMPETITIVENESS OF SOUTHEASTERN FRESH VEGETABLE CROPS USING QUADRATIC PROGRAMMING
Provedor de dados: 31
Autores: Chien,   Ming-Che; Epperson,   James E.
This study determined the competitive potential of the temperate southeastern U.S. region to produce selected fresh vegetables for the national market. Results indicated that the region may be competitive in the production and marketing of snap beans, cucumbers, bell peppers, and spring tomatoes. The region would also be competitive in the production and marketing of broccoli, summer and fall tomatoes, and spinach, given cost reductions of 10 to 15 percent. Major cost reductions were required for the region to be competitive in the production and interregional marketing of sweet onions in the absence of effective product differentiation.

TEXAS FIELD CROPS:  ESTIMATION WITH CURVATURE
Provedor de dados: 31
Autores: Shumway,   C. Richard; Alexander,   William P.; Talpaz,   Hovav.
Some implications of theory are easily maintained in econometric estimation, but computational costs of maintaining curvature properties (sufficient for existence of an optimal solution) have often proved prohibitive. They also have been violated frequently by unrestricted econometric estimates. A computationally manageable procedure for maintaining and testing curvature is used here to obtain estimates of product supplies and input demands for Texas field crops consistent with the theory of the competitive industry. The curvature properties are tested along with several technology restrictions.

DETERMINING FIRM-SPECIFIC VALUES FOR RISKY INVESTMENTS
Provedor de dados: 31
Autores: Atwood,   Joseph A.
This article demonstrates that the usefulness of time-state contingent investment evaluation models need not be constrained by limited time-state contingent markets. Dual solutions to stochastic programs can be used to obtain firm-specific values for risky investments while allowing linear dependence between initial values and later time-state contingent income-technical coefficients. The model could be useful when the exogenous a priori determination of appropriate (and project-specific) risk-adjusted discount rates and/or certainty equivalents is difficult or when the cash equivalents of noncash investment effects are difficult to estimate.

Autores: Tegene,   Abebayehu.
Granger-causality tests and Sims' VAR techniques were used to analyze the impact of macrovariables on farm output and prices in the U.S. for the period 1934-1987. Granger-causality tests show one-way causality from the macrovariables to the farm sector variables, and this is supported by impulse response functions from a VAR model. Money and interest rate effects on agricultural prices and output are apparent in the data.

ECONOMIC SURPLUS AND THE DISTRIBUTIONAL CONSEQUENCES OF DEREGULATING TOBACCO PRODUCTION
Provedor de dados: 31
Autores: Sureshwaran,   Suresh; Thompson,   C. Stassen; Henry,   Mark S.; Loyd,   M.I.
Reservations on technical and theoretical grounds in the use of the consumer surplus approach to measure benefits of government programs have often appeared in the literature. Therefore, this paper uses an alternative approach in a case study to estimate the annual economic surplus created in South Carolina from deregulating tobacco production. Impacts of deregulation on cropping patterns and income on representative tobacco farms, and distribution of benefits in the economy are examined. Results of this study indicate that deregulation stimulates the economy and would increase the net value added by $5.8 million in the long run.

DETERMINANTS OF CONSUMERS' PURCHASE DECISION FOR MAINE ROUND WHITE POTATOES
Provedor de dados: 31
Autores: Cheng,   Hsiang-Tai; Kezis,   Alan S.; Peavey,   Stephanie R.; Smith,   Duane A.
Potatoes are marketed by type (i.e. round white, russet, red, etc.), rather than by variety.  However, the round white varieties currently marketed by the Maine potato industry are known to differ considerably in terms of product characteristics.  This study was designed to test the hypothesis that consumer acceptance of potatoes in home use varies by variety and to quantify how their level of acceptance and other characteristics impact their repurchase decision.  A discrete choice model was used.  The results indicated that consumers do differentiate round white potato varieties based on the performance of the potatoes in home use.  Their willingness to repurchase the round white potatoes is affected by the variety used and the overall serving quality of...

RESTAURANT CONCENTRATION IN LOUISIANA
Provedor de dados: 31
Autores: Schupp,   Alvin R.; Dennis,   Winston.
Growth of the franchise restaurant industry and merger activity among restaurants raise questions concerning concentration in the Louisiana restaurant industry.  Firm employment data from the Louisiana Department of Labor for selected urban and rural parishes for 1975-86 and the concentration ratio, herfindahl index and the entropy measure were used for these concentration estimates.  Concentration was, in general, low in urban parishes and higher in rural parishes.  Concentration decreased from 1975 to 1986 in five of the seven urban parishes and increased or was unchanged in five of the eight rural parishes.  Ceteris paribus, this would imply higher profits in rural as opposed to urban parishes.  The correlation between the concentration ratio and a...

SUPPLY RESPONSE IN THE AUSTRALIAN SHEEP INDUSTRY: A PROFIT FUNCTION APPROACH
Provedor de dados: 31
Autores: Fisher,   Brian S.; Wall,   Charles A.
Profit function models for the three major regions in which the Australian sheep industry operates are specified and estimated. The supply response elasticity estimates are made using a normalised quadratic functional form and time series cross-sectional data. Elasticity estimates, together with their confidence intervals, are presented for the pastoral, wheat-sheep and high rainfall zones. In general, the supply response elasticity estimates derived in this study are lower than those previously reported for studies in which little or no account has been taken of the multi-product nature of Australian agriculture.

Production and Consumption of Foodgrains in India: Implications of Accelerated Economic Growth and Poverty Alleviation
Provedor de dados: 31
Autores: Sarma,   J.S.; Gandhi,   Vasant P.
The role of agriculture in India’s economic development continues to be of great importance, as a producer of food, as an employer of about two-thirds of the labor force, and as a source of purchasing power for much of the nonagricultural consumer goods and services in the economy. Thus, rapid growth in agricultural is essential for sustainable growth and development of the economy. Within agriculture, foodgrain production is by far the major activity, covering about 80 percent of the cropped area in India and providing the main staple source of food. Foodgrains provide almost all the calories and proteins consumed by the poor and provide the rural poor with the bulk of their employment and income. Further, with a population of some 800 million people,...

RISK CONSIDERATIONS IN THE REDUCTION OF NITROGEN FERTILIZER USE IN AGRICULTURAL PRODUCTION
Provedor de dados: 31
Autores: Lambert,   David K.
Nonpoint pollution problems resulting from current agricultural practices are forcing policymakers to examine alternative mitigation strategies. Two mechanisms suggested to control the use of nitrogen fertilizer, a source of potentially harmful contaminants of water sources, are quantitative standards and incentives through per-unit taxation. Impacts of both policies on the distribution of farm net returns are analyzed. Risk attitudes are observed to influence the magnitude of farmer response to alternative policies.

The congruence of beef consumers’ purchases with their stated preferences regarding internal fat content are examined. The role of U.S. Department of Agriculture (USDA) grades and housebrand labeling of beef in providing information to consumers is studied in the theoretical framework of search theory. The empirical results indicate that the current system of USDA grades and housebrand labels is not disseminating information regarding internal fat content effectively to consumers. Suggestions are made for providing consumers with better information and education necessary to increase congruence of expressed preferences regarding internal fat content and actual beef purchases.

We examine the impact of major tax legislation on business capital investment during the 1980-88 period. We detail the tax changes and imbed them into a neoclassical rental price of capital goods. We then use this rental price in two popular models of business fixed investment, a standard and a modified neo-classical model. We estimate these two models along with an accelerator model of capital investment. The models, in general, exhibit parameter instability regardless of fit. We then develop a model incorporating expected delivery lags for new capital goods and embed a forecasted output and the rental price of capital services. Again, parameter instability and fit are examined. Finally we conduct simulations of tax, price and output shocks. We conclude...

EFFECTS OF GENERIC ADVERTISING ON PERCEPTIONS AND BEHAVIOR: THE CASE OF CATFISH
Provedor de dados: 31
Autores: Kinnucan,   Henry W.; Venkateswaran,   Meenakshi.
An eight equation partially-recursive econometric model is specified to indicate the effects of catfish advertising on product awareness, beliefs, attitude and consumption. Results indicate that the ad campaign in its first year (i) increased consumer's awareness on farm-raised catfish 15 percent, (ii) improved consumers' perceptions of and attitude toward catfish 3 to 6 percent, and (iii) increased at-home and restaurant purchases of catfish 12 to 13 percent. The response to the ad campaign is broken down into an "attitude effect" and a "reminder effect" to determine the relative behavioral importance of the affective and cognitive components of the ad copy. Model simulations suggest primacy of the reminder effect, implying the factual content of the ads...

Politically Acceptable Trade Compromises Between The EC and The US: A Game Theory Approach
Provedor de dados: 31
Autores: Johnson,   Martin; Mahe,   Louis Adrien Pascal; Roe,   Terry L.
A model is developed to quantify the special status of agriculture in the US and the EC trade negotiations. The role of special interests are measured by a policy goals function (PGF) whose weights are estimated for each special interest group. The analysis searches for mutually acceptable, mutually advantageous trade agreements between the US and the EC using a partial equilibrium world trade model coupled with game theory. Results suggest that it is in the best interest of the US (resp. EC) 'for the EC (resp. US) to liberalize whi1e the other follows the status quo policies of 1986. Mutual gains in PGF values to both countries pursuing "large" liberalizations are unlikely to exist, although "small" liberalizations may give rise to "small" mutual gains....

Retail food store employees presumably improve the level of satisfaction customers realize during a shopping trip.  A review of the literature revealed few significant contributions supporting or refuting this contention.  A telephone survey of 505 households in Fort Collins, CO during the Fall of 1988 was conducted to generate information on retail food store employees helpfulness.  The findings revealed little explicit impact of helpfulness.  Statistical analysis determined a number of relationships between dollars spent in a store and the perceived level of employee helpfulness.  Retail food stores were not selected, patronized nor avoided based exclusively nor extensively on perceptions of employee helpfulness.  On the other hand, employees were...

SUBSTITUTION BETWEEN WOOLS OF DIFFERENT FIBRE DIAMETER
Provedor de dados: 31
Autores: Beare,   Stephen; Meshios,   Helen.
The extent to which wools with different fibre characteristics can be substituted in textile production and consumption holds implications for Australia's international and domestic marketing policies. An analysis of price-induced substitution between Australian wools of different fibre diameters was conducted. Fibre diameter was used to parameterise cross-price relationships in order to estimate a system of demand equations for wools by diameter class. The results indicate that direct substitution takes place within a very limited range of fibre diameters. The use of product characteristics to parameterise price relationships may be extended to other graded commodities.

EXPLAINING THE DISTRIBUTION OF QUOTA RENTS FROM US CHEESE IMPORTS
Provedor de dados: 31
Autores: Hornig,   Ellen; Boisvert,   Richard N.; Blandford,   David.
A theoretical model is outlined to illustrate how rents are generated from import quotas. The model is used to estimate rents from US cheese import quotas; rents are substantial. Relative rent capture by importers and exporters is explained by estimating an industrial organisation-type model. Unequal market power is important in explaining the distribution of rents between importers and exporters. Exporters tend to maintain price-cost margins and let importers capture a larger share as rent size increases.

An ex ante adoption model of bovine somatotropin (BST) is estimated with survey data of California milk producers. Theoretical justification is developed for incorporation of socioeconomic explanatory variables in a technology-adoption model. The advantages of a multinomial over a binomial ex ante model also are presented. The multinomial logit model is used to predict BST adoption, to test hypotheses on characteristics associated with knowledge and receptiveness towards BST, and to predict potential structural changes in the California dairy industry due to the release of BST technology.

Autores: Carriker,   Gordon L.; Williams,   Jeffery R.; Barnaby,   Glenn Arthur, Jr.; Black,   J. Roy.
This study compares the effectiveness of five crop insurance/disaster assistance plans: an individual farm yield insurance plan similar to the current FCIC multi-peril program ; two area yield insurance plans; a farm yield disaster assistance plan; and an area yield disaster assistance plan. These methods are examined for reduction in yield and gross income variability with and without participation in the government deficiency payment programs using farm-level yield data from 98 dryland wheat farms and 38 dryland corn farms in Kansas . Although individual farm yield insurance is complex, suffers from moral hazard and adverse selection problems, and is likely to be the most expensive to administer , it provides more yield and gross income risk reduction...

A CASE STUDY OF TIMELINESS IN THE SELECTION OF RISK-EFFICIENT MACHINERY COMPLEMENTS
Provedor de dados: 31
Autores: Wetzstein,   Michael E.; Musser,   Wesley N.; McClendon,   Ronald W.; Edwards,   David M.
The importance of timeliness is investigated in the selection of machinery complements for double-crop wheat and soybean production in the southeastern coastal plain. An intertemporal stochastic simulation model was developed to generate probability distributions that were evaluated with stochastic dominance analysis. This research investigated the importance of intertemporal production linkages and adequate soil moisture on machinery selection. Failure to include these dimensions can result in erroneous machinery choices.

Provedor de dados: 31
Autores: Chuzu,   Pia Nwanza.
Zambia, Some County Statistics: Zambia is a landlocked country in the Southern African region. With an area of 74,072,000 hectares (ha) and a population estimated at 7 million, it has one of the lowest person/land ratios in Africa. Its annual population growth rate is high, however, estimated at 3.5 percent (World Development Report, 1988). Zambia's economy is highly dependent on copper earnings. Mineral exports formed 96 percent of total exports in 1986. With generally declining copper prices since 1974 and a rising import bill, Zambia's economy has been severely strained. Fuel imports formed 43 percent of the total imports in 1985, rising from only 10 percent in 1965.  The economy: Despite its efforts to diversify the economy from a mining base to...

Autores: Buschena,   David E.; Perloff,   Jeffrey M.
Legal and institutional changes that centralized control of the Philippine coconut oil refining and exporting industries enabled the Philippines to exercise some of its potential dominant-firm market power. If the elasticity of demand for coconut oil continues to increase. in part due to concerns about the health risks from eating saturated fats. Philippine exports will increase slightly while the price and Philippine revenue will fall significantly within the next decade.

The importance of understorey on wildlife in a brazilian eucalypt plantation
Provedor de dados: 104
Autores: Stallings,Jody R.
Wildlife surveys were conducted in two stands of Eucalyptus, one homogeneous and the other with a native species understorey in the Atlantic forest region of southeastern Brazil Deforestation has reduced the original forested habitat to a patchwork of cultivated fields and mono-specific forestry plantations. Wildlife communities were depauperate in the homogeneous stand, but richer in eucalypt forest with native species understorey. Small mammals, particularly didelphid marsupials, used the understorey rather than the eucalypt emergent trees Primates were absent from both areas. The increasing demand for charcoal for the growing steel industry in the region means that eucalypt plantations will persist until an alternative energy source is found. It is...

A condição das coxas anteriores, do meso-catepímero e do meso-catepisterno dos Tabanidae (Diptera) e sua possível importância na classificação
Provedor de dados: 104
Autores: Bernardi,Nelson.
The condition of certain neglected structures and their possible importance to the classification of the family Tabanidae are studied. The front coxae are considered as belonging to two types: 1) short and robust; 2) long and slender. The posterior edge of the meso-katepimeron presents two conditions: 1) without projection, 2) with backward projection. Similar conditions are found in the meso-Katepisternum, but with intermediate conditions. These characters are discussed in relation to the system proposed for the family by Mackerras. Conditions 1 and 2 of the former two structures separate, respectively, the Pangoniinae and Scepsidinae from the Chrysopsinae and Tabaninae. Condition 2 of the third structure seems to be developing independently in different...

In this paper the authors give a histological analysis of the albumen gland of mature and immature females of Pomacea canaliculata (Lamarck, 1822). In the immaturity, tthe gland doesn't show any secretory activity, although in the maturity this activity is indicated by the presence of a homogeneous and eosinophilic material in its lumen. We could notice in the capsule gland of matures females a calcareous element is present as a granular and basophilic deposit. The albumen gland is envolved by a thin conjunctive layer that can be seen in van Gieson's coloured preparations.

Autores: Cure,José Ricardo; Bastos Fo.,Guilherme S.; Oliveira,Ma. José Faccini de; Souza,Og Francisco de.
The effect of area size, number of collecting hours and months surveyed, on the estimation of relative richness of bees is analized. In order to characterize a biogeographical region, it is suggested to collect various samples of no less than 400 especimens for each one, in contrasting localities within a region, utilizing the usual standardized methodology for wild bees collecting. Thus, it is possible to have a better profit of the effort invested in the survey, making it possible to estimate the relative species richness among different biogeographical regions, in shorter periods of time.

Anatomia e histologia do conduto genital feminino de Pomacea canaliculata (Lamarck, 1822) (Mollusca, Gastropoda, Pilidae)
Provedor de dados: 104
Autores: Mesquita,Eliana de Fátima Marques de; Coelho,Arnaldo Campos dos Santos; Santos,Jefferson Andrade dos.
In this paper the authors give an anatomical and histological analysis of the genital duct in mature and immature females of Pomacea canaliculata (Lamarck, 1822). Anatomically, the vagina has an equal dimension in its extension, varying in form and volume, according to the maturation period. In the immaturity, it has a smaller diameter and volume. In the maturity, the vagina increases in volume, having the aspect of a tumescent organ, and in certain specimens shows an albuminous pink thread in its lumen. Histologically, the calcigenic activity of the gland is evidentiated by the presence of an amorphous and basophilic mass, without nuclear material. This material has a fragmented aspect in the vagina lumen that reacts positively in van Kossa's coloured...

Anatomia e histologia do aparelho reprodutor masculino de Pomacea canaliculata (Lamarck, 1822) (Mollusca, Gastropoda, Pilidae)
Provedor de dados: 104
Autores: Mesquita,Eliana de Fátima Marques de; Coelho,Arnaldo Campos dos Santos; Santos,Jefferson Andrade dos.
In this paper the authors give an anatomical and histological analysis of the male reproductive system of Pomacea canaliculata (Lamarck, 1822). Anatomically, the testis is better evidentiated than the ovary. In the structure of the testis a great number of very small channels converges to a single one. The male copulatory organs result of transformations that take place in the inner surface on the palial membrane. Histologically, the testis of immature males shows seminiferous ducts with round egg-shaped forms. In their lumens we could notice masses of cells that will originate spermatozoids. The penis has a conjunctive muscular sheath that can be seen in van Gieson's coloured preparations.

Provedor de dados: 104
Autores: Velez,Imelda; Thatcher,Vernon.
Nudacotyle carollia sp. nov. (Trematoda, Nudacotylidae) is described on the basis of specimens from the intestinal tracts of three Colombian bats of the species Carollia perspicillata L. The new species resembles both of the genera of the family, Nudacotyle and Neocotyle, in the general position of the organs and in having a vertical cleft. It differs from Nudacotyle in the position of the ovary and cirrus sac and in the lenth of the ceca. The new species differs from Neocotyle in the shape of the body and the vitelline lobes and in the length of the ceca. The ventral cleft is considered to be an important generic character which can be used to unit all the species of both genera in the single genus, Nudacotyle.

Paratrygon aiereba (Müller &amp;amp; Henle, 1841): the senior synonym of the freshwater stingray disceus thayeri Garman, 1913 (chondrichthyes: potamotrygonidae)
Provedor de dados: 104
Autores: Rosa,Ricardo S.
A review of the original descriptions and available types of the South American freshwater stingrays Trygon aiereba Müller &amp;amp; Henle, 1841, Trygon strogylopterus Schomburgk, 1843 and Disceus thayeri Garman, 1913 indicates that these three nominal species are synonymous. The senior name, placed in the monotypic genus Paratrygon Duméril, 1865, established for Trygon aiereba, is available and valid. Based on its description, T. aiereba is a freshwater stingray. Therefore, this taxon is not the same as Raja ajereba Walbaum and Raja orbicularis Schneider, both names established for the marine "Aiereba" of Marcgrave, and which preferably should be treated as nomina dubia. Paratrygon does not replace Potamotrygon Garman, 1877 as the type genus, because the...

Fruits are predated by man and seeds by rodents. Lateral shoots grow weell with enough light or show leaf etiolation and reduced number in shade. Two seedlings were found, with low leaf number, riolated petioles and low leaf area, suggesting extremely slow growth in shade. Reproduction appears to depend upon natural or manmade clearings, the former of insuficient duration to permit natural regeneration. This, combined with other modifications, confirms pejibaye's status as a full domesticate.

São comparadas num mesmo latossolo podzólico amarelo de textura média, situações sob vegetação natural, depois da queimada, após um e cinco anos de cultivo e após três anos de pousio consecutivos a dois anos de cultivo. Depois da queimada e um ano de cultivo, há uma forte diminuição de todos os resíduos vegetais. Esta diminuição foi quantidade na liteira e na camada 0-15 cm do solo através do fracionamento granulométrico da matéria orgânica. Esta evolução continua durante os cinco anos de cultivo e se inverte quando o solo é abandonado à capoeira após dois anos de cultivo. O carbono da fração 0-50 μm, que concentra o complexo argilo-húmico, não sofre grandes variações quantitativas. O fracionamento químico desta fração mostra que, sob cultivo, o húmus é...

Autores: Fisch,Gilberto.
The purpose of this study is to analyse the climatic aspects of the data collected in a forest site in comparison with conventional data obtained at different sites, such as clearing, rural an urban areas. The results showed that diverse climatic conditions do exist among the sites: the urban site showed higher temperature and lower relative humidity. In addition, evapotranspiration (potential and actual rates) was computed from the forest data set, using the classical Penman-Monteith's equation. The actual evapotranspiration is 30% of the potential value during dry period and seems to be almost constant during the whole year (tipically 2.0 to 2.5 mm day-1).

Biologia de Anofelinos Amazônicos. XIII. Estudo do ciclo biológico de Anopheles nuñez-tovari Gabaldon, 1940 (Diptera, Culicidae)
Provedor de dados: 36
Autores: Scarpassa,Vera Margarete; Tadei,Wanderli Pedro.
No estudo do ciclo biológico de Anopheles nuñez-tovari foram analisadas 108 posturas, totalizando 13.999 ovos. A média de ovos postos por postura foi de 128,83 + 4,85 e uma taxa de eclosão elevada de 84,06%. Foi constatado qe 89% dos ovos eclodem com 48 horas após a oviposição, mostrando, no total, um período médio de eclosão de 1,86 + 0,004 dias. A média de ovos eclodidos por postura foi de 109,39 + 5,26. Os dados de correlação entre ovos postos e ovos eclodidos evidenciaram que à medida que aumenta o número de ovos por postura há também um aumento correspondente na taxa de eclosão . Contudo, quando as posturas são reunidas em intervalos de classe de 40 ovos, constatou-se que não há correlação para algumas delas. Para as fases imaturas, verificou-se que...

A situação da Citotaxonomia de angiospermas nos trópicos e, em particular, no Brasil
Provedor de dados: 39
Autores: Guerra,Marcelo.
A citotaxonomia vegetal desenvolveu-se inicialmente nos países do primeiro mundo, acumulando dados e estabelecendo modelos evolutivos baseados principalmente em táxons e floras temperadas. A introdução de técnicas citogenéticas mais refinadas tem permitido uma análise mais acurada da variabilidade cariotípica, mas até o momento estes novos métodos têm sido aplicados apenas a um número muito pequeno de táxons. Assim, o principal instrumento do citotaxonomista continua sendo a variabilidade cromossômica numérica. A região tropical ainda é muito carente de dados, especialmente os trópicos americanos. No Brasil, a citotaxonomia se desenvolveu como parte da citogenética e não como uma abordagem taxonômica. Mesmo assim, nos últimos anos tem crescido o número de...

Provedor de dados: 39
Autores: Mori,Scott.
As Lecythidaceae (família da castanha-do-Pará) são árvores tropicais de planície que atingiram sua maior diversidade em espécies nos neotrópicos. No Novo Mundo, a família está mais diversificada em habitats de terra firme na Amazônia e nas Guianas. Pouco mais de 50% de todas as espécies neotropicais de Lecythidaceae são encontradas na Amazônia, sendo a Amazônia central especialmente rica em espécies. Uma única área de 1,00 hectares, 90 Km ao norte de Manaus apresenta 38 espécies diferentes de Lecythidaceae. Além disso, um grande número de espécies de Lecythidaceae têm o centro de distribuição na província floristica das Guianas. As espécies de Lecythidaceae com flores actinomórficas são mais numerosas no noroeste da América do Sul, enquanto que as espécies...

Autores: Clark,Lynn G.
The present paper analyses the distribution of bamboos in New World. For convenience, bamboos are divided into two broad groups, the woody bamboos and the herbaceous bamboos. These categories do not necessarily reflect phylogenetic relationships among bamboo groups. The Bambuseae includes all of the woody bamboos and is probably monophyletic, whereas the herbaceous bamboos are classified into eight tribes. In the New World (including underscribed taxa), 45-46 genera and approximately 515 species are represented; only two genera: Arundinaria and Streptogyna are not exclusively neotropical. The area of greatest endemism and diversity is the humid coastal forests of Bahia, Brazil. 22 genera have been found in this relatively small area, representing 48% of...

Provedor de dados: 39
Autores: Grangeiro,T.B; De Oliveira,J.T.A; Moreira,R.A; Cavada,B.S.
Sementes de Dioclea rostrata Benth. Têm uma lectina que é melhor extraída em tampão acetato de sódio a pH 4,0 e é seletivamente adsorvida em Sephadex G-50, apresentando um alto título de hemaglutinação contra eritrócitos de coelho. A lectina também aglutina inespecificamente hemácias de carneiro e humanas. A atividade hemaglutinante é inibida por glicose, frutose, manose e alfa-metil-D-manosídeo, sendo os dois últimos os mais potentes inibidores. A lectina é uma metaloproteína, uma vez que a atividade hemaglutinamente desaparece na presença de EDTA.

Variação intraespecífica dos nutrientes em folhas de Methodorea pubescens (Rutaceae) em dois tipos de mata do Distrito Federal
Provedor de dados: 39
Autores: Nascimento,Marcelo Trindade; Hay,John Duvall.
Metrodorea pubescens é uma árvore comum nas matas do Distrito Federal, ocorrendo em matas mesofíticas (solos calcáreos) e matas de galeria (solos ácidos). Em cada tipo de mata foram coletadas todas as folhas de 15 indivíduos jovens, sendo cinco por classe de altura (5-50, 50-100, e 100-150 cm). As folhas foram separadas em três categorias: novas, maduras e senescentes e depois foram secas e analisados para os seguintes elementos: P, K, Ca, Mg e Al. A concentração dos nutrientes nas folhas não diferiu em relação ao tamanho dos indivíduos. Apenas o alumínio apresentou menores teores nos indivíduos de 5-50 cm. As folhas novas apresentaram maiores teores de P e K. Já o Ca, Mg, e Al foram maiores nas folhas maduras. Há um decréscimo de P da folha madura para...

Provedor de dados: 39
Autores: Almeida,Francisco Célio Guedes; Almeida,Francisco Aécio Guedes; Almeida,Francisco Flávio Guedes; Carvalho,Paulo Rogério de.
O cajueiro é uma planta geralmente propagada por semente. Sua multiplicação vegetativa ainda não é comercialmente viável. Neste estudo os efeitos do estiolamento e do ácido indolebutírico (AIB) na formação de raízes do alporque da planta de caju foram investigados. O estiolamento foi realizado 30 dias antes do início do processo de alporquia. Por ocasião do anelamento do ramo, o AIB foi aplicado. Após 30 dias da realização da alporquia, os ramos já enraizados foram removidos da planta progenitora. Em seguida foram colocados em saco plástico na casa de vegetação sob condições de irrigação intermitente. Os resultados sugeriram um prévio estiolamento do ramo antes do processo de alporquia e uma aplicação de AIB, por ocasião do anelamento para, garantir a...

Diversidade taxonômica e distribuição geográfica das Orchidaceae brasileiras
Provedor de dados: 39
Autores: Barros,Fábio de.
Orchidaceae é uma das maiores famílias do Reino Vegetal, e sua distribuição geográfica obedece a limites definidos já a nivel de sub-famílias. O genero Laelia, com 7 seções das quais 5 ocorrentes no Brasil, apresenta características evolutivas interessantes, principalmente a sect. Parviflorae, que ocorre predominantemente em Minas Gerais e que representa um exemplo de "evolução explosiva" ainda em andamento. Os tratamentos taxonómicos dados a cada diferente grupo dentro da família não se apresentam uniformes, o que leva à aceitação de um grande número de gêneros pequenos em alguns grupos e de poucos gêneros grandes e complexos, em outros grupos.

Provedor de dados: 39
Autores: Acevedo-Rodriguez,Pedro.
The present paper analyzes the distribution of Serjania in Brazil, by comparing and contrasting the species occuring in three major phytogeographic regions: the Atlantic coast, the planalto, and the Amazon basin. The Atlantic coast region has the highest percent (70%) of species endemic to the area, and shares many species with the planalto region. The planalto region shares most of its species with the Atlantic coast and the neighboring countries, but still has a 33% of endemic species to the area. The Amazon basin has only a 4% of species endemic to the area, with most of the reminder species widely distributed through-out the area.

Estudo comparativo entre o desenvolvimento de plântulas de milho após período de exposição a vários potenciais hídricos
Provedor de dados: 43
Autores: Silva,W.R. da; Marcos Filho,J.
Submetendo sementes de milho com e sem tratamento fungicida, a ambientes de germinação variáveis quanto à disponibilidade de água (0 a -12atm), o presente trabalho avaliou o desenvolvimento posterior das plântulas postas em ambientes sem limitações hídricas. Os resultados obtidos permitiram concluir que a ocorrência de déficit hídrico, durante o início do processo de germinação, promove reduções posteriores no comprimento das estruturas embrionárias e, de forma mais acentuada, do epicótilo; apesar disso, esse efeito se atenua com o passar do tempo pela elevação progressiva na velocidade de crescimento em ambientes que oferecem menores potenciais hídricos. Paralelamente, o tratamento fungicida das sementes pode não trazer vantagens em ambientes hidricamente...

Levedura de panificaçao (Saccharomyces cerevisiae) foi obtida anaerobicamente (sem e com adição dos ácidos graxos palmítico, oleico e linoleico) e aerobicamente e utilizada em ensaios de fermentação com 14% e 16% de sacarose a 32°C. Não houve diferenças significativas, quanto a viabilidade celular, entre os tratamentos das leveduras com ácido oleico, ácido linoleico e aerobicamente (as quais foram ricas em palmitoleico e oleico). As leveduras enriquecidas com ácido palmítico e anaeróbicas apresentaram maior redução na viabilidade do que com ácidos graxos insaturados. Foi observado um aumento na produção de ácido pirúvico e uma redução nos álcoois superiores com a redução da viabilidade celular.

A fase larval do predador Nusalala uruguaya (Navás, 1923) alimentada com pulgão-preto-dos-citros Toxoptera citricidus (Kirk), pulgão-da-couve Brevicoryne brassicae (L.) e pulgão-do-picao Dactynotus sp. foi estudada, em condições de laboratório à 25 ± 2°C, UR de 70±10% e fotofase de 14 horas. A espécie de presa consumida afetou a fase larval do predador, influenciando a duração e a viabilidade de cada instar, a largura da cápsula cefálica, o peso e o tamanho de suas larvas. Dactynotus sp. foi a espécie mais consumida e que propiciou o melhor desenvolvimento larval, sendo que T. citricidus acarretou 100% de mortalidade no primeiro instar. As larvas de N. uruguaya somente se alimentaram de pre-ovos e larvas da sua própria espécie.

Efeito de várias disponibilidades hídricas, atuando como pré-condicionamento fisiológico durante a germinação das sementes de milho, no desenvolvimento das plântulas
Provedor de dados: 43
Autores: Silva,W.R.da; Marcos Filho,J.
O presente trabalho buscou estimar os eventuais efeitos de pré-condicionamento fisiológico promovidos, durante o início da germinação das sementes de milho, por ambientes variáveis quanto à disponibilidade de água (0 a -12 atm). Para tanto, os períodos de deficiência eram sucedidos por prazos fixos de 5 dias sem limitações hídricas e comparados com uma testemunha que permaneceu, igualmente, sem restrições quanto à disponibilidade de água durante 5 dias. Os resultados encontrados indicaram que a técnica de pré-condicionamento hídrico das sementes pode, se devidamente adaptada em seus detalhes, propiciar algumas vantagens no desenvolvimento das plântulas delas oriundas. Adicionalmente, o tratamento químico fungicida das sementes, submetidas a...

Avaliação da embebição e do desenvolvimento inicial das estruturas embrionárias de sementes de milho submetidas a diferentes potenciais hídricos
Provedor de dados: 43
Autores: Silva,W.R.da; Marcos Filho,J.
Empregando substratos com potenciais hídricos variáveis entre 0 e -12atm, o presente trabalho objetivou avaliar o comportamento das sementes de milho postas a germinar. As situações de deficiência hídrica foram diretamente comparadas à testemunha (plena disponibilidade de água), usando sementes com e sem tratamento fungicida. A análise e a interpretação dos resultados permitiram concluir que a absorção de água, a emergência e o desenvolvimento inicial das estruturas embrionárias são interdependentes e reagem no mesmo sentido ao déficit hídrico; para esses casos, a redução do potencial hídrico promove dificuldades na evolução dos processos. Paralelamente, a presença de tratamento fungicida pode não influenciar, quantitativamente, os fenômenos envolvidos no...

Decomposição de resíduos de cultura de milho (Zea mays L.) medida pelo teor de carbono e relação C/N do solo
Provedor de dados: 43
Autores: Albuquerque,G.A.C. de; Mello,F.de A.F. de.
Foi feito um ensaio em vasos com três solos arenosos do município de Piracicaba a fim de se avaliar o período de decomposição mais ativa de restos de cultura de milho e início de estabilização desse processo e testar a determinação do teor de C do solo e da relação C/N como parâmetros de avaliação da decomposição. Utilizou-se o delineamento experimental inteiramente casualizado, com e sem adição do material orgânico e com adição de doses crescentes de nitrogênio. Concluiu-se o seguinte: a) Tanto o teor de C do solo como a relação C/N foram eficientes para alcançar o objetivo visado, devendo-se, entretanto, para fins práticos, utilizar o primeiro processo por ser de execução mais fácil e mais rápida, b) A decomposição tendeu a se estabilizar aos 45 dias,...

Ácaros do pinheiro-do-Paraná em Lages, Santa Catarina
Provedor de dados: 43
Autores: Fenilli,R.; Flechtmann,C.H.W.
Coletas quinzenais de ácaros de ramos do Pinheiro-do-Paraná, Araucária angustifolia, em Lages, Santa Catarina, revelaram a presença, durante um ano (Setembro de 1983 a Agosto de 1984) das espécies fitófagas Oligonychus urunguis (Jacobi) e Tydeus formosus (Cooreman) e de ácaros predadores da família Phytoseiidae, dos gêneros Amblyseius e Proprioseiopsis. Também ácaros oribatídeos foram coletados durante todo o ano. De ocorrência mais restrita foram obtidos ácaros das famílias Ascidae, Bdellidae, Cheyletidae e Acaridae. O método de coleta batendo-se o material vegetal sobre tela e bandeja revelou-se pouco mais eficiente do que o emprego do funil de Tullgren.

Acúmulo de trealose em linhagens de Saccharomyces durante fermentação alcoólica
Provedor de dados: 43
Autores: Gutierrez,L.E.
A pesquisa foi realizada para comparar os efeitos de diversos fatores (temperatura, pH, concentração de sacarose, 2,4-dinitrofenol e fontes de nitrogênio) sobre a produção de trealose em Saccharomyces uvarum IZ-1904 e Saccharomyces cerevisiae (M-300-A e de panificaçao) durante a fermentação alcoólica. Com a levedura IZ-1904 houve menor produção de trealose do que M-300-A e de panificaçao. A trealose foi formada em maior quantidade (p &lt; 0,05) a 34°C. Em pH 4,5 houve maior acúmulo de trealose do que em pH 3,0 para as leveduras M-300-A e de panificaçao. A adição de 18ppm de 2,4-dinitrofenol acarretou decréscimo (p &lt; 0,05) na quantidade de trealose formada pela levedura de panificaçao e sem efeito para IZ-1904. O aumento da concentração de sacarose...

Mapeamento de solos através do caráter espectral, da rede de drenagem e da vegetação
Provedor de dados: 43
Autores: Marchetti,D.A.; Garcia,G.J.
O presente trabalho reuniu três metodologias conhecidas para o estudo de solos, todas associadas às técnicas de sensoriamento remoto. Para uma mesma área, os solos foram relacionados aos seus parâmetros espectrais obtidos digitalmente de imagens de satélite; os índices de drenagem da área foram também relacionados aos respectivos solos; a conhecida relação entre tipos de cerrado e respectivos solos suporte foi também estudada. Para cada situação foi preparado um mapa de solos, que se aproximava do mapa já existente. Quando as informações de tais mapas foram agregadas em um único mapa, a aproximação com o mapa de controle foi altamente satisfatória evidenciando a aplicabilidade da metodologia.

No ano agrícola de 1986/87, nas Estações Experimentais de Mococa e Ribeirão Preto, efetuaram-se experimentos com o objetivo de avaliar o efeito da aplicação de níveis crescentes de calcário dolomítico (0, 4, 8 e 12t/ha) sobre os teores de óleo e proteína nos grãos dos cultivares de soja IAC-Foscarin-31, IAC-11, IAC-12 e Cristalina. Os maiores teores de óleo e de protefna foram observados nos grãos colhidos em Mococa. Independentemente da calagem e das localidades, o 'IAC-12' apresentou as maiores produções médias de óleo e proteína por área, 561 e 963kg/ha respectivamente. Em todas as localidades, a calagem promoveu a elevação do teor de proteína e a redução do teor de óleo nos grãos. A produção de óleo e proteína (kg/ha) aumentou linearmente com os níveis...

Pré-embebição em água e porcentagem e velocidade de emergência de sementes de palmiteiro
Provedor de dados: 53
Autores: Bovi,Marilene Leão Alves.
Quatro períodos de pré-embebição em água foram aplicados a frutos e sementes de palmiteiro (Euterpe edulis Mart.) visando determinar seus efeitos na velocidade, na porcentagem e na duração média do processo de emergência. A pré-embebição do fruto foi prejudicial à porcentagem final e velocidade de emergência, provavelmente por permitir maior contaminação por microorganismos patogênicos. A aplicação desse tratamento por dois dias em sementes mostrou efeito benéfico sobre a porcentagem final, não sendo, porém, eficiente para acelerar sua emergência. Períodos maiores do que dois dias foram prejudiciais, tanto à porcentagem como à velocidade de emergência. O uso de frutos despolpados acelerou e aumentou a emergência, diminuindo o tempo médio do processo...

Provedor de dados: 53
Autores: Boaventura,Yone M. Sellito.
Realizou-se o estudo do comportamento meiótico de C. canephora tetraplóide com 2n =44 cromossomos por tratar-se de uma espécie considerada possível ancestral de C. arabica (2n = 44): constatou-se, em 92,0% das células-mães de pólen, em todas as fases da microsporogênese estudada, 2n = 44 cromossomos. Em diacinese os cromossomos se apresentaram na forma de mono-, bi-, tri- e tetravalentes. Em metáfase 1, somente 13,16% das células apresentaram 22II sendo a seguinte a fórmula média do pareamento: 3,61I; 15,21II 0,71III e 1,93IV. As irregularidades anafásicas resumiram-se praticamente na disjunção desigual dos cromossomos para os pólos de 21-23, 20-24 e 19-25. Somente 37,65% das células apresentaram segregação normal de 22 cromossomos para cada pólo. Em...

Autores: Guerreiro Filho,Oliveiro; Medina Filho,Herculano Penna; Gonçalves,Wallace; Carvalho,Alcides.
Estudaram-se diversos parâmetros agronômicos em progênies oriundas de potinização aberta e de hibridações envolvendo os cafeeiros C 1195-5-6-1 e C 1195-5-6-2, resistentes ao bicho-mineiro (Perileucoptera coffeella). Ambos apresentam florescimento abundante e precocidade de maturação, características da espécie Coffea racemosa, da qual se originaram por retrocruzamentos com C. arabica. Hibridações desses dois cafeeiros foram realizadas com os cafés Icatu, Catimor, Híbrido de Timor e Catuaí. Os três primeiros, derivados de retrocruzamentos de C. canephora com C. arabica, são resistentes ao agente da ferrugem (Hemileia vastatrix) e, o último, cultivar de grande expressão econômica, tem porte reduzido e elevada capacidade produtiva.

Organogênese floral do pessegueiro in vitro
Provedor de dados: 53
Autores: Barbosa,Wilson; Campo Dall'orto,Fernando Antonio; Ojima,Mario.
Coletaram-se meristemas do pessegueiro 'Tropical' (Prunus persica L. Batsch) em 30 de outubro, 30 de novembro e 30 de dezembro de I986 e 30 de janeiro e 28 de fevereiro de 1987 e cultivados in vitro. Aqueles coletados até 30 de novembro desenvolveram-se vegetativamente, produzindo vitroplantas normais de pessegueiro. O mesmo não ocorreu com os meristemas coletados em dezembro, janeiro e fevereiro, os quais se transformaram em botões florais após quinze dias de cultivo in vitro. Evidenciou-se, assim, que o processo de indução floral para o pessegueiro 'Tropical' ocorreu em dezembro na região de Jundiaí, SP (23°08'S.), uma vez que nenhuma vitroplanta se desenvolveu após esse período. Evidenciou-se, ainda, a irreversibilidade dos meristemas após o processo...

Provedor de dados: 122
Autores: Benítez, Lilyan.
El Ecuador como Estado independiente contó desde 1830 con una Constitución y un cuerpo de leyes para normar las diferentes actividades de la sociedad. Junto con las leyes generales se expidió la Ley Especial de oriente con disposiciones específicas para reglamentar las actividades en esta región, la misma que rigió hasta 1969, cuando fue incorporada al Régimen Administrativo General del Estado. Si bien es cierto que las limitaciones de un Estado débilmente articulado y con presupuestos restringidos puede explicar, en una primera aproximación, el manejo de la reg10n como una zona marginal, no es menos cierto que en el fondo de la cuestión pueden encontrarse otros argumentos que provienen de concepciones ideológicas o de las necesidades de acumulación del...

Autores: Alvear, Ana Lucía.
El 10 de agosto de 1988, el presidente Borja terminaba su discurso de posesión con una frase alusiva a la soledad del poder, que parecía fuera de lugar, pronunciada frente a un Congreso integrado por absoluta mayoría de diputados del partido de gobierno y de su aliada DP. Hoy, transcurridos dos años, el pronunciamiento del presidente cobra vigencia en una práctica del ejecutivo que tiende a ser cotidiana.

Los campesinos obreros de la construcción (Ciudades)

Autores: González, Iván.
Al deambular por las calles del centro de la ciudad de Cuenca, en la plaza de San Francisco, el caminante se topará durante los primeros días de cada semana, con un nutrido grupo de personas charlando, criticando la carestía de la vida y la falta de trabajo, aguardando con confianza o recelo. Son los obreros de la construcción que buscan un contrato. Llegan desde los pueblos que rodean a la ciudad, pedaleando sus bicicletas en largas caravanas mañaneras, e invierten el recorrido por las tardes para retornar a la casa, la agricultura, la artesanía, a la vida del campo.

En las últimas elecciones municipales realizadas en noviembre de 1989, la coalición de las izquierdas (FRENTE AMPLIO) obtuvo la mayoría relativa de sufragios (34,8%), logrando acceder al gobierno local por primera vez en la historia (Intendente -Alcalde- y mayoría de la Junta Municipal). La propuesta electoral del Frente Amplio en su campaña municipal se centró en el tema de la participación popular-y la descentralización, concretada en la idea de crear 18 Centros Comunales Zonales (CCZ) en el conjunto del Departamento de Montevideo. Habiendo ganado las elecciones nacional es una coalición de centro-derecha (Partido Nacional o Blanco) que tiene el apoyo de la mayoría del otro partido "tradicional" (Partido Colorado) para su programa de severo ajuste...

Provedor de dados: 122
Autores: Torres Galarza, Ramón.
El tránsito de la sociedad agraria a los procesos de urbanización dejó profundas huellas en las actuales formas de organización social y del Estado en el Ecuador. La herencia de la sociedad agraria y el intento de modernización del Estado, creó un Derecho no correspondiente con los procesos sociales y los cambios que se producían. En el ámbito urbano esta falta de correspondencia del Derecho se torna más evidente por cuanto la violación de los derechos  de los pobladores existen en cada acto y cada día.

El proceso migratorio en el austro ecuatoriano no es un fenómeno nuevo. El minifundio, la mala calidad de la tierra, las crisis cíclicas de las actividades artesanales (tejidos, cerámica, paja toquilla, calzado y otras) han golpeado duramente a las frágiles economías campesinas y artesanales urbanas, obligándolas a encontrar en el trabajo extra parcelario y migratorio, el ingreso complementario destinado a cubrir las necesidades de subsistencia.

Las obras, proyectos y leyes han sido sustituidos por la vocinglería y el escándalo, mientras el cálculo político se ha puesto por encima del servicio a la comunidad.

El consumo de chicha, guarapos y aguardientes forma parte importante de la vida de los pueblos andinos. La chicha, en particular, ha constituido desde tiempos antiguos uno de los recursos privilegiados en la comunicación con los otros y con lo desconocido. Aún en el mundo contemporáneo y en el mundo de la ciudad, la chicha, combinada con puntas y licores baratos, guarda un significado simbólico especial en el ceremonial de los migrantes y entre los pobladores de las comunas urbanas. No es que el consumo de bebidas sea exclusivo de los andinos, pero no cabe duda que cada pueblo (o pueblos) tiene su forma peculiar de perderse (y ganarse) con ellas.

En 1979 nuestro país retoma al orden constitucional. En todo el continente se expande el mapa de las democracias constitucionales. El tiempo de las dictaduras militares se cierra. Los diferentes países escogen diversos caminos para estos retornos: Asambleas Constituyentes, nuevas Constituciones. Pero en todos los casos la nueva legitimidad se asienta en el voto popular. En el Ecuador el retomo constitucional encuentra a una nueva clase obrera, constituida al calor del boom petrolero, iniciado en 1972, bajo la dictadura de Rodríguez Lara. El movimiento sindical se fortaleció y logró constituirse en una de las fuerzas fundamentales en la lucha contra la dictadura. Precisamente en medio de estas luchas se consolida un proceso unitario de las centrales...

Nuestro análisis parte de una primera proposición: aunque existe una copiosa legislación que trata múltiples aspectos de la vida urbana, no se ha desarrollado en el Ecuador un "derecho urbano".

Una breve revisión de las áreas más importantes, permitirá evaluar el alcance de esta afirmación.

Cuando Henri Michaux, al finalizar la segunda década del siglo actual, vino a Quito invitado por ese empinado y excepcional poeta nuestro que fue Alfredo Gangotena (cuya poesía tanto se comenta y tan parcamente se conoce), para emprender en una extravagante y fallida aventura de atravesar el Continente por la Amazonía, siguiendo la ruta de Orellana; observó a la ciudad tan pequeña que la consideró un pueblecito asido a un cráter de nubes donde las montañas, al abatirse sobre él, lo cobijaban asombradas. Fue ésta una visión fugaz y poco laudatoria, quizás injustificable, porque aquel poeta procedía de la metrópoli gala y, según confesaba, él necesitaba de una ciudad "con un gran consumo de envidia", diferente a la nuestra donde "todos aquí en voz baja y...

El material preparado aborda entre otros temas una problemática poco discutida en nuestro país: el derecho urbano. Todos debemos movernos, de un modo o de otro, sujetos a una maraña de reglamentaciones y normas que muchas veces ni siquiera comprendemos o, peor aún, conocemos. Parece ser que en el caso de la legislación urbana el problema se complica por el caos de que está hecha: dispersa en varios cuerpos legales, obsoleta y contradictoria; su racionalización parece ser exigencia urgente. Pero no se trata tan solamente de eso. Los textos que componen este bloque temático nos llaman la atención sobre el hecho de que la ley es una creación social e histórica.
