O estudo relaciona-se a agricultura familiar e sua variante especial, os assentamentos rurais. Sua perspectiva e a de uma analise socioambiental, dado que os processos de degradação tem sempre tanto determinações como efeitos sociais. A partir da analise do período da modernização, bem como da base de recursos naturais dos agroecossistemas (potencial de biodiversidade restante dos sistemas agrícolas) familiares, o mesmo busca subsidiar a discussão sobre a concepção de novos desenhos de sistemas agrícolas ecologicamente sustentáveis.

Desempenho reprodutivo de cabras mestiças anglo-nubianas em três diferentes épocas de cobertura, no Acre.
Provedor de dados: Informação Tecnológica em Agricultura (Infoteca-e)
Autores: MAIA, M. da S.
Nas regiões tropicais, onde as condições climáticas são relativamente constantes o ano todo, e onde não ocorrem variações aparentes no fotoperíodo, a atividade reprodutiva dos caprinos se estende por todos os meses do ano. No entanto, a eficiência reprodutiva do rebanho resulta da interação entre o patrimônio genético do indivíduo e o meio ambiente. Desta forma, a manipulação do ambiente no sentido de oferecer aos animais melhores condições de manejo, resultará em maiores índices produtivos. O estabelecimento de uma estação de cobertura que contemple os eventos cobertura, parição e desmame com épocas que lhes sejam favoráveis, possibilitará ao criador a obtenção de uma maior produtividade do rebanho e, conseqüentemente, maior lucro com a exploração. Neste...

This report gives the result of macrofauna densities and biomasses, for the dry and rainy seasons, in five systems: 1) primary forest; 2) long-term pasture (15 years) (called old pasture); 3) long-term (11 years) abandoned (in 1992) pasture (called pasture degr); 4) short-term ( 5 years) abandoned (in 1987) pasture (called pasture aband); and 5) short-term (5 years) pasture turned to capoeira (in 1987) and then to agrosylvicultural systems in 1991 (called agsosylv.). Preliminary results: a) dry season - macrofauna biomasses and densitiesshowed high differences between plots; b) rainy season - the degraded pasture was notsampled at this date. A few macrofauna groups are dominante in these systems. Other groups less abundant were also present (Diptera...

Em grandes áreas irrigadas das Regiões Centro-Oeste e Sudeste, o feijão tem se constituído na principal alternativa para o cultivo no período de inverno. Entretanto, a excessiva mão-de-obra necessária na colheita, para o arranquio e enleiramento das plantas, e um problema de grande relevância para os produtores. Reconhecendo tal importância, a EMBRAPA, através do Centro Nacional de Pesquisa de Arroz e Feijão, num esforço conjunto com a industria de maquinas e com a participação do produtor, conduziu um projeto em Goiânia (GO), Paracatu (MG) e Formoso (TO), visando o desenvolvimento de tecnologias que viabilizem a colheita totalmente mecanizada do feijoeiro. Os resultados obtidos, ate então, em testes com as colhedoras Ford New Holland e Maxion, ambas com...

Provedor de dados: Informação Tecnológica em Agricultura (Infoteca-e)
Autores: NUNES, M. U. C.; OLIVEIRA, J. B. de; FAZOLIN, M.
O repolho (Brassica oleracea var. Capitata) é, economicamente, a hortaliça mais importante da família das brássicas. Constitui uma excelente fonte de sais minerais, principalmente cálcio e fósforo, além de vitaminas A, B e C, sendo também, um alimento bastante versátil à mesa e de fácil digestão. O baixo conteúdo de açúcares permite o consumo de 100g diárias, sem prejuízos às pessoas diabéticas. Na família das brássicas é a hortaliça de maior teor de vitamina C. A composição nutritiva varia com fatores ambientais, irrigação, adubação, estágio de desenvolvimento na colheita, métodos de estocagem, processamento caseiro e industrial e cultivares. Na medicina natural é usado como estimulante do crescimento de cabelo, nevralgias faciais e dentárias, úlceras...

A primeira tentativa de incrementar a exploração de caprinos e ovinos no Acre foi implementada pelo Programa de Desenvolvimento Rural Integrado do Acre - POR!, que no ano de 1985 financiou um projeto de produção de caprinos da raça Anglonubiana e ovinos das raças Santa Inês e Morada Nova, sob coordenação da EMBRAPA, então UEPAE de Rio Branco, com o objetivo de produzir e distribuir matrizes e reprodutores destas raças aos colonos assentados pelo Instituto Nacional de Colonização e Reforma Agrária (INCRA), no Estado. Isso culminou, ainda em 1985, com a importação de animais das raças acima citadas, da Região Nordeste. A raça Santa Inês originou-se na Região Nordeste, provavelmente por meio de cruzamentos entre carneiros da raça Bergamácia com ovelhas...

Recomendações técnicas para o enraizamento de estacas herbáceas de pimenta-do-reino nas condições edafoclimáticas do Acre.
Provedor de dados: Informação Tecnológica em Agricultura (Infoteca-e)
Autores: PIMENTEL, F. A.; LODI, N. V.
A pimenta-do-reino (Piper nigrum L.) vem sendo cultivada no Estado do Acre desde a década de 80. A não expansão da cultura deve-se, principalmente, à carência de material genético, à baixa produção de mudas, bem como ao número reduzido de informações técnico-científicas dessa piperacea nas condições edafoclimáticas do estado. Assim, foi conduzido um experimento, em fevereiro de 1992, onde foram testados quatro métodos de enraizamento, visando oferecer alternativas no uso de substratos para o enraizamento de estacas herbáceas de pimenta-do-reino.

Provedor de dados: Informação Tecnológica em Agricultura (Infoteca-e)
Autores: NUNES, M. U. C.; OLIVEIRA, J. B. de; FAZOLIN, M.
A cenoura (Daucus carota L.) é um alimento rico, principalmente em cálcio e vitamina A, que juntamente com o baixo valor calórico e o teor de fibra em tomo de 2%, fazem desta um alimento indicado na dieta de crianças, pessoas convalescentes e pessoas anêmicas. A coloração alaranjada indica a presença de B-caroteno, que no organismo humano transforma-se em vitamina A, essencial à visão. A tecnologia de produção ora disponível, permite incentivar o cultivo e o maior consumo de cenoura no Estado do Acre, onde verifica-se a necessidade de uma dieta mais rica em vitaminas e sais minerais.

O Brasil ostenta a primeira posição na produção mundial de frutas, com 30 milhões de toneladas em uma área cultivada de 2,3 milhões de hectares. A desorganização dos sistemas de produção e a inexistência de técnicas adequadas de pós-colheita, entretanto, ensejam perdas expressivas na produção, variando de 15 a 40%. As condições brasileira para a produção de frutas, tanto para o mercado interno, como para o mercado externo, confere-lhes vantagens comparativas em ralação aos países correntes devido as condições climáticas favoráveis, grande disponibilidade de área e acervo razoável, representa a região com maior potencial para a produção de frutas tropicais tendo em vista os solos e climas adequados, o que tem proporcionado um rápido crescimento da...

Autores: OLIVEIRA, M. V. N. d'.
Foi realizado um inventário florestal em 195 ha de floresta no Centro de Pesquisa Agroflorestal do Acre (CPAF-Acre), da EMBRAPA. A floresta inventariada foi dividida em três estratos: floresta densa, floresta aberta e capoeira. Foram avaliados o potencial para extração madeireira e o extrativismo. A floresta densa foi a que apresentou os melhores resultados para produção madeireira, com 29 espécies comerciais listadas e média de 35,953 m3 de volume de madeira (árvores com DAP &gt; 50 cm) de espécies de interesse econômico por hectare. A floresta aberta, apesar de possuir um volume significativamente menor (27,04 m3/ha) ainda pode ser considerada apta para manejo com vistas à produção de madeira. A capoeira, presente em 47% da área, teve sua origem em...

Vantagens e limitações dos capins Tanzânia-1 e Mombaça para a formação de pastagens no Acre.
Provedor de dados: Informação Tecnológica em Agricultura (Infoteca-e)
Autores: VALENTIM, J. F.; MOREIRA, P.
Os problemas da pecuária no Acre incluem a falta de adaptação e persistência produtiva das forrageiras utilizadas na formação de pastagens, aliada à sua baixa qualidade, especificamente durante o período da seca. Novas cultivares forrageiras devem ser introduzidas como mais um dos componentes para a diversificação das pastagens nos sistemas de produção animal do Acre, permitindo reduzir os riscos de perda dos pastos pelo ataque de pragas e doenças, aumentando a oferta de alimento de boa qualidade e em quantidade suficiente para satisfazer às necessidades nutricionais dos animais durante o ano todo.

Urucui - cultivar de arroz de sequeiro de ciclo precoce para o Piaui.
Provedor de dados: Informação Tecnológica em Agricultura (Infoteca-e)
Autores: CAMPELO, G. J. de A.; PEREIRA, J. A.; TEIXEIRA NETO, M. L.
A orizicultura tem uma grande importancia social e economica para o Piaui. Segundo a FIBGE (1991), na safra de 1988/89 foram produzidos 347.919 toneladas de arroz numa area de 261.903 ha, o que colocou o Estadono nono lugar em producao entre todas as unidades da Federacao. O manejo da cultura, os frequentes periodos de defic hidrico que ocorrem durante as fases de desenvolvimento do arroz e o uso de cultivares com ciclo relativamente longo e a baixa estabilidade produtiva sao apontadoscomo as principais causas desse fraco desempenho. Para fazer face a essa realidade, a EMBRAPA/CPAMN, vem desenvolvendo um projeto de melhoramento de arroz de sequeiro, onde, entre outros objetivos, procura identificar cultivares de ciclo precoce (em torno de 100dias), porte...

Considerações sobre a caprinocultura no Brasil.
Provedor de dados: Informação Tecnológica em Agricultura (Infoteca-e)
Autores: MAIA, M. da S.
Os caprinos foram introduzidos no Brasil pelos colonizadores portugueses, juntamente com os primeiros animais domésticos por volta de 1535. Provavelmente, as raças aqui introduzidas tenham sido aquelas criadas em Portugal e regiões limítrofes da Espanha, na época (Silva Neto, 1950; Figueiredo, 1981; Figueiredo et al. 1987). No Brasil, a caprinocultura se faz presente em todas as regiões do país. Porém, 89,8% do efetivo do rebanho nacional está distri-buído na região Nordeste, tendo como principais produtores, os Estados da Bahia, Piauí, Pernambuco e Ceará.

Recomendações técnicas para formação de mudas de castanha-do-brasil (Bertholletia excelsa HBK).
Provedor de dados: Informação Tecnológica em Agricultura (Infoteca-e)
Autores: MOREIRA, P.
Embora reconhecida como relevante econômica e socialmente para a Região Norte, a castanha-do-brasil jamais recebeu a devida atenção das autoridades governamentais amazônidas. Mesmo protegida pela Portaria nº 2570 de 28/02167 do IBDF, que proíbe o abate da castanheira (Bertholletia excelsa HBK), a sua população, na Amazônia, foi drasticamente reduzida pelos desmatamentos ocorridos nas décadas de 1970 e 1980. Hoje, ainda que a derrubada desta Lecythidaceae ocorra em menores proporções, necessário se faz a implantação de uma política de incentivo ao cultivo racional, nos moldes que se apresentou o Programa de Incentivo à Borracha Vegetal (PROBOR), tendo-se o cuidado de corrigir os graves erros de conccpção e condução daquele programa.

Estudo voltado para a regiao semi-arida do Nordeste brasileiro, visa a espacializacao e a caracterizacao fito-edafica das areas com processos de degradacao ambiental. Relata-se que alem da atuacao predatoria do homem, o tipo de solo e o principal condicionante da intensidade da pauperizacao da biodiversidade. Assim foram definidos 4 graus de degradacao ambiental, ligados a 4 tipos ou associacoes de solos com suas respectivas distribuicoes nos Estados do Nordeste, perfazendo um total de aproximadamente 20 milhoes de hectares. Salienta-se ainda que a degradacao ambiental nesta regiao, nao pode ser considerada como um processo irreversivel, sendo possivel, na maioria dos casos, uma reabilitacao natural num espaco de tempo relativamente curto.

The neurohormonal induction of the release of oocytes and sperm from Pecten maximus
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Devauchelle, Nicole; Micarelli, P; Guerrier, P; Desilets, J.
In order to induce in vitro maturation of Pecten maximus oocytes, experiments were carried out using different concentrations of the serotonin and dopamine agonists TFMPP, 8-OHDPAT, quinpirole and bromocriptine. The greatest germinal vesicle breakdown (GVBD) occurred using TFMPP. Metaphasic blocks were rarely observed. Oocytes treated with TFMPP at 10 super(-3) and 5x10 super(-4) M could be fertilized at low levels. The maximum fertilization rate recorded was 23%. A second series of experiments was conducted to determine the effects of serotonin, dopamine, the agonists cited above and PGE sub(2) on the release of oocytes and sperm from P. maximus. These inducers were injected into both the male and female parts of the gonads and spermiation was...

Recirculation is it viable ? Is it insurable ?
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Paquotte, Philippe.
Recirculation techniques in aquaculture exist and are applied at an industrial scale in sea-bass, sea-bream and turbot rearing for sho rt (incubation, larval rearing, weaning) or long (broodstock) rearing phases whatever the biomass. Experiments are carried out by IFREMER in partnership with producers and equipment makers to develop super intensive fish production in closed system. From the economic viewpoint, recirculation makes it possible to reduce fingerling production cost while it is still unknown in the case of ongrowing. From the insurance viewpoint, recirculation will make risk appraisal and risk m anagement easier. [NOT CONTROLLED OCR]

Year-to-Year changes in meteorological features of the french coast area during the last half-century - examples of 2 biological responses
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Fromentin, Jean-marc; Ibanez, F.
Chronological series (1949 to 1992) of air temperature, precipitation, atmospheric pressure and wind in different parts of the French coast show evidence of important year-to-year changes, trends and cycles: seven-eight years for temperature, and around three years for precipitation and atmospheric pressure. On the scale of France, it appears that spatial heterogeneity of meteorological factors is smaller than temporal heterogeneity. New methods, such as the cumulative sums method or the envelopes of a variable reveal the interest for ecologists of essaying different numerical approaches. A comparison between climatic series and biological series of a benthic and a pelagic species is described for this purpose.

Compte-rendu de la campagne "Resubguy 4" (mai 1994) sur le plateau continental de la Z.E.E. guyanaise
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Rose, Joel.
Le cycle biologique du principal stock de crevettes pénéïdes (Penaeus subtilis) exploité sur le plateau continental guyanais est court (18 mois environ). Les variabilités intra et inter annuelles de l'abondance des individus appartenant aux différentes composantes des premières phases du cycle (larves, post-larves, juvéniles) sont considérées comme très fortes, ce phénomène étant exacerbé par le double changement de milieu au cours du cycle, passage d'un habitat en eau salée à celui en eau douce, puis retour au premier.  La pêcherie de la flottille crevettière guyanaise est ainsi basée sur un stock au renouvellement rapide et variable, aussi l'optimisation de sa gestion implique une meilleure compréhension des mécanismes de recrutement des crevettes et...

Etude des sources potentielles de contamination microbienne sur le bassin versant d'une zone conchylicole en Sud Vendée
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Felgines, Dorothée.
Les zones littorales connaissent souvent une multiplicité d'usages : la saliculture, la pisciculture, l'agriculture, le tourisme, l' urbanisme et la conchyliculture. Pour cette dernière activité, c'est à la fois les apports d'eau salée et d'eau douce, riche en nutriments qui peuvent constituer des conditions idéales au développement des coquillages. Mais ces zones conchylicoles sont particulièrement sensibles au niveau de la qualité de l'eau. Situées en aval, elles reçoivent directement à marée basse les apports terrigènes contenus dans l'eau douce. Si ces apports peuvent être intéressants pour les conchyliculteurs, car ils sont en partie nécessaires à l' alimentation des coquillages, ils peuvent être également une source de contamination bactérienne...

Étude de matière humique sédimentaire par application de la technique de pyrolyse-chromatographie liquide-chromatographie gazeuse
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Noureddin, S; Vandenbroucke, M; Courtot, P.
Preparative pyrolysis followed by liquid chromatographic separation and gas chromatography of hydrocarbons (Pyrolysis-LC-GC) were used to study the participation of terrestrial and/or aquatic compounds in the formation of humic substances in sediments. Analyses performed on humic substances from recent sediments sampled in the Elorn river estuary (France) show that these substances are similar in many respects to other lacustrine or marine humic substances, with regard, for instance, to their high nitrogen and sulphur content and their low aromaticity. Mass balances on pyrolysis products and group composition of the C-14+ fraction of the pyrolysates were performed. The distribution of the total alkane and alkene fraction, isocyclo alkanes and alkenes from...

South equatorial current of the indian-ocean - a 50-day oscillation
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Heywood, Kj; Barton, Ed; Allen, Gl.
Observations of a fifty-day oscillation in the meridional component of the South Equatorial Current in the Western Indian Ocean are presented. Currents measured in 4000 m of water close to the atoll of Aldabra (46-degrees-E, 9-degrees-S) reveal the oscillation throughout the water column to a depth of 3 000 m. Further evidence of the oscillation is presented in shipboard Acoustic Doppler Current Profiler (ADCP) sections and in Coastal Zone Color Scanner (CZCS) imagery. The oscillations are consistent with a zonally propagating Rossby wave caused by shear instability in the zonal flow of the South Equatorial Current.

Culturable heterotrophic bacteria from the euphotic zone of the indian-ocean during the summer monsoon
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Nair, S; Bharathi, Pal; Chandramohan, D.
Cuturable heterotrophic bacterial counts (viable counts: VC) by surface plating on ZoBell medium and total bacterial counts (TC) by epifluorescence microscopy were carried out in sea water off the southwest coast of India during the monsoon. TC were three orders of magnitude higher than VC. Pseudomonas/Alteromonas group I was dominant in both nearshore and offshore regions. Pigmented bacteria were more abundant in offshore stations and showed multiple antibiotic resistance. Statistically there was found to be no significant differences in bacterial number and their activities between offshore and nearshore isolates. Nevertheless, the former tend to be more versatile and resistant to metals and drugs.

Autores: Faure, Catherine; Devauchelle, Nicole; Girard, J.p; Cosson, J.
Sperm of the scallop Pecten maximus (L.) can be collected by various methods for artificial reproduction. Characteristics such as spermiation time, fertilizing capacity, respiration and motility of the spe can be modified by collection method. In the current study, sperm was collected quickly by scarification, but its quality was only average. When thermal shock or serotonin injection was used to stimulate the release of sperm, it was collected and concentrated as "dry" as possible after exit fr the kidney. Its quality was comparable to that of diluted sperm collected after thermal shock, a technique commonly used in bivalve hatcheries. The results also showed that serotonin injection systematically decreased spermiation time and induced the production of...

Autores: L'Helguen, S.; Le Corre, P.
Les quantités d'éléments nutritifs, en particulier d'azote, et de matière organique déversées par les fleuves dans les eaux côtières ont considérablement augmenté ces dernières années en raison d'une part d'une intensification des pratiques agricoles, d'autre part, d'une industrialisation et d'une urbanisation croissante des zones littorales. Ces apports peuvent, à une échelle locale ou à mésoéchelle, modifier de manière importante le fonctionnement des écosystèmes côtiers. Ils peuvent, en particulier, en enrichissant le milieu en azote intensifier les processus d'absorption du phytoplancton et déclencher des proliférations algales.

Autores: Verlaque, M.
This review addresses the problem of recently introduced plants in the Mediterranean in order to analyse their vectors, the dispersal processes and the possible ecological and economic consequences. Ninety-five cases (94 macroscopic algae and one seagrass) are listed and discussed. Three major routes of access into the Mediterranean are indicated: shipping, the Suez canal and aqua-culture. The recent introduction of Caulerpa taxifolia along our coasts has called attention to a new potential source: aquaria. Among the successful acclimatizations, cold-temperate Pacific and Atlantic species remain confined to the north of the Mediterranean (Gulf of Lions, Adriatic), whereas some tropical or sub-tropical plants colonize large areas. Some introduced algae...

Autores: Renault, Tristan; Le Deuff, Rose-marie; Cochennec, Nathalie; Maffart, Patricia.
Sporadic mortalities were reported in june and july of 1992 and 1993 among batches of hatchery-reared larval Pacifie oyster, Crassastrea gigas, and at the beginning of July and in August of 1993 among five batches of 3-7 month old young spats, C. gigas. Observations with transmission electron microscope showed the presence of herpes-like virus particles in infected larvae and young spats. The viruses observed in diseased larvae and affected young spat oysters were very similar. Elevated temperature and crowding may increase susceptibility of oysters to these herpes-like virus infections.

Fisheries are managed by stocks. A stock is defined by species and geographical area. Their management is international including all the countries which have a fishing activity in each geographical area. The International Council for Exploration of the Sea (ICES) is an international structure which undertakes to organize working groups each year. The groups are made up of scientists from different countries. Those experts are put in charge of assessing the most important stocks. The main results of these assessments are described in that report. The most important French and international landings of demersal fishes and nephrops in North-Eastern Atlantic are presented in the introduction of the report. The species are cod, whiting, saithe, haddock, sole,...

Combined effects of temperature-salinity on larval survival of the Eastern oyster Crassostrea virginica in the Maryland portion of the Chesapeak Bay (USA)
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Goulletquer, Philippe; Heral, Maurice; Prou, Jean.
Oyster landings in the Maryland portion of the Chesapeake Bay have declined by more than 50fold since the early part of the century, despite intensive management efforts. The annual shell repletion program is the most critical programmatic element to effect recovery of the ailing Eastern oyster Crassotrea virginica stock and fishery. The overall efficacy of shell repletion management depends primarily on the success of spat settlement on the planted shell, and furthermore on their survival rate. The Operations Research techniques and mathematical programming developed by Rothschild et al. (1991) attempt to maximize spat recruitment to the oyster stock subject to a series of operational constraints. Allocation and timing of shell deployment are the most...

Simulation of long equatorial waves in the pacific-ocean in relation with sea-level oscillations and zonal mean currents
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Brossier, F; Monier, L; Delecluse, P.
Wave-Like oscillations over a period of 30 days, with a wavelength of 1 000 to 1 200 km, have been observed in the Pacific Ocean between 2 degrees N and 4 degrees N. Eddies with the same time-space scale are present in the sea-level oscillations observed by satellites. A numerical modelling of these long equatorial waves is presented in this paper. Fluctuations of currents and density around given mean fields are computed by a cyclic perturbation model. The oceanic response has to fit given sea-level oscillations. Three sea-level data sets have been considered : one is deduced from Geosat altimetric measurements; the other two are analytically constructed, with random time-dependence. Three mean circulations have also been studied : no mean flow, and mean...

Some results of a cruise carried out within the Project on the Physical Oceanography of the Eastern Mediterranean (POEM BC-091, October 1991) are reported and discussed. The major aim of this work was to study, in the upper layers of the Ionian basin the distribution of particulate matter, phytoplankton and bacteria, with emphasis on the influence of North Atlantic Water. Some tentative conclusions may be drawn from the results: the examined situation (October) is representative of the final stage of a probably annual cycle of production in an oligotrophic system; the well-developed Deep Chlorophyll Maximum between 75 and 100 m (mainly due to degradation products) does not match the biomass maximum. Possible explanations of this are: a) phytoplankton...

Variability of delta-c-13 of sigma-co2 in ocean waters of the equatorial pacific
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Laubelenfant, E; Pierre, C.
The transect from East to West Pacific realized along the equator during the Alize 2 cruise (January-March 1991) offers a unique opportunity to evaluate the effect of the equatorial upwelling on the partial derivative(13)C values of Sigma CO2 in oceanic waters. The surface partial derivative(13)C distribution from 95 degrees W to 165 degrees E is characterized by a general increase from 0.90 to 1.54 parts per thousand which parallels the temperature rise from 23 to 30 degrees C, both giving a signature of the upwelling and of the westward advection of superficial waters: the C-13 depletion in the Sigma CO2 marks the progressive influence of upwelled waters which are rich in C-13-depleted CO2 generated by organic matter remineralization.

Autores: Levy, A.
Archaias angulatus is a soritid species found in abundance on littoral intertropical carbonate platforms. In the margino-littoral euryhaline biotopes, wedged in the neighbouring littoral marine environment, lives a distinct but similar form: Androsina lucasi. As the latter cannot migrate by sea or be transported by birds or fish, it cannot have been derived phylogenetically from an ancestral species before colonizing this wedged habitat in space and time. Only the idea of a reiterated phenomenon of speciation induced by the environment from another littoral species (Archaias angulatus) can explain its noticeable ubiquity in margino-littoral biotopes isolated from one another but each in contact with the biotopes favoured by Archaias angulatus.

Autores: Robledo, Jaf; Boulo, Viviane; Mialhe, Eric; Despres, Béatrice; Figueras, Antonio.
Digestive glands of mussels Mytilus edulis from Brittany, France, infected with Marteilia sp. (Ascetospora) were used to purify the parasite. A modification of a previously used purification protocol increased purification efficiency, permitting sporangial primordia and sporangia of Marteilia sp. to be obtained. Mouse (Balb/c) monoclonal antibodies were generated against this parasite. From the fusion, 26 monoclonal antibodies against Marteilia sp. were obtained. Antibodies from 6 clones reacted only with Marteilia sp. cells and not with normal host tissues. Four of these antibodies (1/1-3, 3/1-1, 4/1-1 and 6/2-3) reacted with the sporangia wall and two with the spore cytoplasm (9/1-1 and 12/5-1). Antibodies cross-reacted with Marteilia refringens from...

Concomitant enrichments of uranium, molybdenum and arsenic in suboxic continental-margin sediments
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Legeleux, F; Reyss, Jl; Bonte, P; Organo, C.
Elemental analyses were carried out by Neutron Activation Analysis on eleven sediment cores from the North-East Tropical Atlantic, collected at two sites of the French EUMELI programme. Total uranium, molybdenum and arsenic concentrations increase from the surface to about 20 cm depth in cores from the eutrophic site, but remain constant in cores from the mesotrophic site. These profiles clearly highlight an enrichment of the three elements in the sediments from the eutrophic site, linked to the suboxic conditions encountered in these sediments. This entrapping of uranium in suboxic sediments, observed in previous studies (Barnes and Cochran, 1990; Klinkhammer and Palmer, 1991), is thus confirmed at the EUMELI eutrophic site. Furthermore, other elements,...

Due to lack of knowledge about the seabass (Lates calcarifer) market in Polynesia, various production levels were considered to develop a managing tool for decision, making relevant development strategy and adapted rearing technology. This work is an analysis of the economical parameters of known rearing techniques depending on various production levels.  The comparative study of the techniques, phase by phase, regarding the production cost and the investments prompted us to select the semi-intensive larval rearing technology under the current economical conditions. However, the larval rearing extensive technique could be of highest interest for productions lower than 60 metric tons a year. Growing-out in floating net-cages appeared to be the only...

Autores: Bertrand, Jacques; Catanzano, Joseph; Rey, Hélène; Tempier, Elisabeth.
The beginning of the 1990s was marked by the will of French and European Community policy makers to change the methods of managing fishing in the Mediterranean. To contribute to this dynamic by an analysis on fishing operations based on exploitation itself and by developing proposals to reinforce participation of fishing professionals in the management of regional fishing were the objectives of the study presented below. The research was conducted based on principles of action research, involving a common discussion among the actors. Within a context of implementing the principle of subsidiarity and Community integration, it became necessary to anticipate the methods of reinforcing the capacity of professional facilities so that the latter could continue...

Estimating the sea-state bias of the topex and Poseidon altimeters from crossover differences
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Gaspar, P; Ogor, Florian; Le Traon, Pierre-yves; Zanife, Oz.
TOPEX (Ku band) and POSEIDON altimeter measurements at crossover points are used to estimate the sea state bias (SSB) of these two instruments. Different SSB models are tested, ranging from a constant fraction of the significant wave height (SWH) to more elaborate models involving up to four adjustable parameters. For TOPEX, the data show a decrease in the magnitude of the relative bias (SSB/SWH) with SWH. This behavior is well reproduced using a simple empirical model with two adjustable parameters. The three-parameter SSB model used in the NASA geophysical data records does well in explaining the wind-induced variations of the bias. A model including four adjustable parameters is needed to account for both the wind- and SWH-related variability of the...

Optimization of triploid induction by the use of 6-DMAP for the oyster Crassostrea gigas (Thunberg)
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Gerard, Andre; Naciri, Yamama; Peignon, Jean-marie; Ledu, Christophe.
A novel method using 6-dimcthylaminopurinc (6-0MAP) has recently been demonstrated to be a good triploid inductor for bivalve molluscs. The effects of 6-DMAP concentration, timing of treatment after fertilization and treatment duration on survival and triploid induction of Crassostrea gigas (Thunberg) embryos were examined. An influence of sperm concentration was also detected and discussed. Survival to D-stage was inversely related to 6-DMAP concentration and the percentage of triploids was shown to be 6-DMAP dose dependent. Two optimal moments for treatment application were determined corresponding to extrusions of the first and second polar bodies. Optimal treatment of 450 µmol/l 6-DMAP beginning 15 min after fertilization over a 10 min period yielded...

Organic-carbon and humic-acids in sediments of the arabian sea and factors governing their distribution
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Sardessai, S.
Organic carbon and humic acids in the sediments of the Arabian Sea show distinct regional variations to the south and north of 15-degrees-N latitude. Significant variations are also observed from the shelf of the slope regions. Organic carbon and humic acids are enriched on the slope compared to the inner and outer shelf. While upwelling, primary productivity and redox conditions at the bottom are known to influence organic matter accumulation in sediments, bacterial population and sediment texture also contribute to the preservation of organic matter and humic acids. A positive correlation (r = 0.716) between total organic carbon and humic acid content in the sediments indicates fairly favourable conditions for the humification of organic matter. The C/N...

Autores: Chatain, Beatrice.
By gathering specific measurement criteria and an objective analysis  of field methods, the main purpose of this work is to help estimate larval Sea Bass (Dicentrarchus labrax) and Sea Bream {Sparus auratus) stock performance raised under intensive conditions. As such, it is a  methodology guide zootechnicians can use, in their daily quantitative and  qualitative evaluation stock issues. The first part of this work covers defining the precision of current counting  methods and establishing their limitations. The quantification methods  analysed, as well as the new proposed methods, relate to the major phases of larval farming, from laying to postlarval stage. Three field methods commonly used in aquaculture to quantify egg population  are therefore...

A mathematical model for the determination of the shape and the tensions of a trawl placed in a uniform current
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Theret, Francois.
The determination of trawls shapes and tensions is a very complex problem. At this time only the static aspect has been considered, the trawl being placed into a uniform current. Three types of difficulties have been met : - Firstly, the hydrodynamic behaviour of the meshes is not well known ; - Secondly, a net is a complete flexible structure with no own shape unless submitted to the action of external forces, but so we are facing an actual " fluid-structure interaction" problem ; - Thirdly, a flexible reticulate structure is made of an anisotropie and discontinus material. ln this paper, the net studied is a trawl for which, the only parameters known are the drawing and the characteristics of the cables which link it to the trawler. The method that we...

Tropical instability waves in the atlantic-ocean - a contributor to biological processes
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Morliere, A; Lebouteiller, A; Citeau, J.
Long tropical instability waves are described at around 3-4 degrees N based on results of a simulation performed with a general circulation model for the Atlantic Ocean. This description is in agreement with earlier observations of organized undulations of the summer thermal front associated with anti-cyclonic eddies propagating westward at 30-40 km/day along 3-4 degrees N from 10 to 40 degrees W through the Atlantic basin. However, the simulation indicated the presence of long waves in early boreal winter. In this respect, satellite observations during short cold events in winter show thermal front undulations similar to those associated with long wave propagations. The simulation clearly demonstrated large vertical movements between the surface and a...

Estimation de la biomasse d'huîtres non cultivées dans le bassin de Marennes-Oléron
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Prou, Jean; Pouvreau, Stephane; Renaud, Vivian.
In the Marennes-Oléron oyster culture basin, the cultivated oyster stock shows an unbalanced age distribution: 25 000 to 30 000 tonnes are commercialized each year for a total cultivated biomass of 95 000 tonnes (1993). The biological overexploitation of the basin requires a reduction of the stock in order to get back to productivity rates that are compatible with the restrictions of the oyster market. This study gives an estimated natural deposit biomass of around 3 000 tonnes. An estimate of the abandoned and wild oyster biomass shows that 20 000 tonnes of these animals can be considered as competitors to cultivated oysters. [...].

Autores: Suquet, Marc; Billard, Roland; Cosson, Jacky; Dorange, Germaine; Chauvaud, Laurent; Mugnier, Chantal; Fauvel, Christian.
This paper presents some features of turbot sperm and compares them with data reported in the literature on other freshwater and marine fish. In captivity, turbot spermiation period lasts 6 months. When compared to other fish species, turbot males are characterized by low values of maximum gonadosomatic index (0.6-0.8%) and are poor sperm producers in terms of volume (0.2-2.2 ml), concentration (0.7-11.0 x 10(9) spermatozoa/ml) and total sperm number released per stripping (0.2-12.0 x 10(9) spermatozoa). Compared to most freshwater species, the duration of cell movement is long (1-17 min). The spermatozoon of turbot can be considered to be of a primitive type. A very high protein content (8.8 mg/ml) is found in the seminal fluid of turbot. Increasing...

Autores: Lundberg, L.
The net air-sea exchange of CO2 in the ocean area enclosed by the Fram Strait in the north and by the Greenland-Scotland ridge in the south is estimated on the basis of oceanic pCO(2) data from three different expeditions. The data comprise observed pCO(2) as well as pCO(2) calculated from data on dissolved inorganic carbon (C-t), total alkalinity (TA) and pH. Data on atmospheric content of CO2 are available from two of the expeditions and are supplemented with monthly mean values from ocean station ''M'' (66 degrees N, 2 degrees E). Wind speed drawn from a data set with a spatial resolution of 75 km and a temporal resolution of six hours are used in the calculation. The pCO(2) data are interpolated to the same spatial resolution as that of the wind speed...

Autores: Bassinot, Franck; Beaufort, Luc; Vincent, Edith; Labeyrie, Laurent; Rostek, Frauke; Muller, Pj; Quidelleur, Xavier; Lancelot, Y.
We examined coarse fraction contents of pelagic carbonates deposited between 2000- and 3700-m water depth in the tropical Indian Ocean using ocean Drilling Program (ODP) sites 722 (Owen Ridge, Arabian Sea) and 758 (Ninetyeast Ridge, eastern equatorial Indian Ocean), and four giant piston cores collected by the French RN Marion Dufresne during the SEYMAMA expedition. Over the last 1500 kyr, coarse fraction records display high-amplitude oscillations with an irregular wavelength on the order of approximately 500 kyr. These oscillations can be correlated throughout the entire equatorial Indian Ocean, from the Seychelles area eastward to the Ninetyeast Ridge, and into the Arabian Sea. Changes in grain size mainly result from changes in carbonate dissolution as...

Autores: Guezennec, Jean; Rimbault, A; Godfroy, Anne; Fromage, M; Marec, F; Rocchiocioli, F.
The existence of deep-sea hydrothermal thermophilic archaebacteria raises interesting questions about their metabolism and metabolic products both in a natural environment and in a culture medium. Moreover, the use of these microorganisms as a potential source of molecules of biotechnological interest must be considered, in the light of the fact that metabolic produits can enhance the risk of microbially-induced corrosion. Organic acids formed by an anaerobic thermophilic sulphur-dependent archaebacterium were analysed as tert-butyldimethylsilyl derivatives by GC and GC/MS. Data indicated the presence in significant amounts of propanoic, 2-methyl propanoic, 3-(methylthio) propanoic, phenylacetic and 4-hydroxyphenylacetic acids. In addition, the use of...

Rifting consequences of three plate separation
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Sibuet, Jean-claude; Srivastava, Shiri.
Submarine sedimentary basins parallel to the trends of passive continental margins are well explained by tensional processes between two lithospheric plates. This leaves open the enigma of many basins which strike across margins. We use examples from the North Atlantic to show that such basins may be formed during the initial rifting stage due to enhanced lithospheric thinning caused by the separation of three plates. We suggest that volcanics can be emplaced in these basins and, in the extreme case, where mantle temperature and consequently the degree of partial melting are particularly high, that basaltic flows can be thick enough to fill and hide the basins.

Parsimonious analysis, a method used in cladistics, which considers the coherence of characters, is used to establish the phylogeny of different taxa. Its use in the analysis of ecological and biogeographical data in marine benthic studies remains rare. Application to data collected from ecological or biogeographical works and previously studied by classical analysis demonstrates the potential and the advantages of this method in the study of spatio-temporal marine benthic series.

Situations et perspectives de l'aquaculture mondiale
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Ferlin, Philippe; Michel, Alain; Paquotte, Philippe.
On a global scale, aquaculture produced around 17 million tonnes in 1991, compared with 11 million tonnes in 1985 and 6 million tonnes in 1975. Since the beginning of the 80s, this production increased by an average of 7.5% per year in volume, and more than 13% in value. This amount represents only 17 tonnes of the global volume of sea and fresh water products, but more than 25% of its value. On a worldwide scale, water products account for an important part of the animal product supply in human food. For example, aquaculture accounts for a larger part than ovine production and represents around 5% of the world's animal protein supply. Aquaculture is an activity that is still booming from a technological development point of view and should be one of the...

Shallow-water volcanic edifices in high-resolution seismic-reflection profiles - examples from the gulf of naples (italy)
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Fusi, N.
The Gulf of Naples (southern Italy) is well known for active subaerial volcanism (Somma-Vesuvius and Phlegrean Fields). Several shallow submarine volcanic edifices are known to exist around the Phlegrean area, but these have never been studied in detail. These volcanoes, located on the shelf, at a maximum depth of 150 m, are characterized by two different seismic facies in high-resolution seismic reflection profiles: 1) chaotic reflections, with variable amplitude and frequency; 2) in-phase reflections, with low frequency and high amplitude or high frequency and low amplitude. Seismic facies (1) is interpreted as an image of massive volcanic deposits, such as lava flows, domes, pyroclastic flows or lahars; while seismic facies (2) is interpreted as...

Recherche de biomarqueurs de toxicité liés à l'activité estérase non spécifique et à la résistance multixénobiotique chez divers organismes marins
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Minier, Christophe.
The atm of this work was to find new non-specifie biomarkers to biomonitor the environmental impact of xénobiotics in marine organisms : the non-specifie esterase activity and the multixenobiotic resistance phenomena (MXR) similar to the multidrug resistance phenomena (MDR). As for the esterase activity, a simple and rapid method based on fluorescent measurements of fluorescein diacetate (FDA) has been developed with unicellular micro-algae : Calothrix sp. , Haslea ostrearia and Prorocentrum micans. This biomarker is very sensitive to many physical and chemical factors such as light intensity, temperature,  salinity, stage of growth and, among the main marine pollutants, to organophosphates and, in a lesser extent, to polycyclic aromatic hydrocarbons...

Conséquence sur la santé de la consommation des coquillages de pêche à pied dans le bassin d'Arcachon en période estivale
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Achard-stablo, Catherine.
La consommation de coquillages, bien que représentant une faible part de la ration alimentaire, pose tm réel problème de santé publique. Ces mollusques, filtrant une grande quantité d'eau, concentrent les micro-organismes du milieu pouvant entraîner un risque pour le consommateur. Le risque sanitaire encouru à la suite d'ingestion de coquillages est essentiellement bactérien ou viral. Cela nécessite une surveillance des gisements naturels, au même titre que des sites d'élevage. La qualité de l'évaluation du ii.sque pose le délicat choix des indicateurs de contamination (virus, bactéries pathogènes et formes viables non cultivables). Dans ce travail, nous avons essayé de mettre en relation les troubles digestifs observés dans la population, en période...

INTRODUCTION: Norway Lobster fisheries in the Celtic Sea are mostly located in the Vllg and Vllh subdivisions. The communal regulation applying to Norway Lobster mesh size has been in effect since 1978. The use of derogative mesh size to catch Norway Lobsters is only allowed if the percentage of species protected by marketable size caught at the same time as Norway Lobsters is inferior to a fixed threshold in relation to the mesh size in effect. This regulation has been applied according to a specific schedule.  With a percentage of protected species higher than 60 %, catching is considered as geared towards fish and mesh size is what the global regulation requires, i.e. 80 mm. As a matter of fact, as it has been mentioned many times, under the pressure of...

The submersible-study of four segments of the East Pacific Rise between 17 degrees and 18 degrees 40'S, where the spreading rate is greater than 150 mm/a, allows us to confirm the variability of the accretion processes. The segment between 17 degrees and 17 degrees 30'S shows an intense present-day magmatic activity. The one between 18 degrees 10' and 18 degrees 22'S shows a mainly tectonic activity. The segment between 18 degrees 22' and 18 degrees 37'S is an intermediate stage with an axial graben in which fresh lavas were emplaced by an extremely young eruption. On all the segments the hydrothermal activity exists ranging from shimmering water up to black smokers, It is associated with different stages of animal colonization.

Le chrome en milieu marin
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Chiffoleau, Jean-francois.
This document constitutes a synthesis of current knowledge on the chromium biogeochemical cycle. The natural and anthropogenic sources are evaluated, the fluxes between the various geochemical compartments are assessed, with special attention to the riverine and atmospheric inputs to the marine environment. Chromium levels in these compartments are described and show in several areas a very high contamination of marine organisms. Due to the important toxicity of this element, further investigations are absolutely required to better understand its behaviour in the marine environment.

A quasi-meridional hydrographic section carried out between 60-degrees and 20-degrees-N offshore from the European and African continental slopes is analyzed in terms of water masses and zonal transports in and out of the eastern boundary. Outstanding features of the meridional distribution of water masses are focused on, such as the transition between North Atlantic and South Atlantic Central Waters at 20-degrees-25-degrees-N, the properties and anticyclonic circulation of the Rockall Channel mode water, and the northern boundary of the large-scale Mediterranean Water plume at about 50-degrees-N. An eastward transport of about 11 X 10(6) m3 s-1 is found to enter the eastern boundary layer at densities lower than 27.25 and feed southward alongshore...

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

Species dominance and niche breadth in bloom and non-bloom phytoplankton populations
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Ignatiades, L.
This paper describes the quantitative relationships between phytoplankton abundance and species number, dominance and niche breadth during ''bloom'' and ''non-bloom'' stages in a coastal marine environment of the Eastern Mediterranean Sea. Analysis of the relative frequency distribution of the species breadth per sample showed each assemblage to be a mixture of species with narrow (&lt; 3), moderate (4-8) and broad (&gt; 8) niche breadth. Assemblages with higher (&gt; 30) numbers of species tended to have a greater proportion (up to 25-30 %) of species with narrow breadth in relation to the samples with fewer taxa. In ''bloom'' assemblages, the total cell abundance increased above the concentration level of ''non-bloom'' assemblages (baseline population)...

Autores: Le Grand, Jacqueline.
En 1983, l'IFREMER met en place un REseau de surveillance PHYtoplanctonique (REPHY) sur tout le littoral français dont l'un des objectifs est la protection de la santé publique. Il permet de suivre continuellement l'évolution de la flore phytoplanctonique dans l'eau et de cerner les risques dus à l'apparition d'espèces toxiques (Dinophysis). En Normandie, l'évolution de la production phytoplanctonique est caractérisée par un bloom printanier et parfois un second plus faible en automne. Le phytoplancton est essentiellement composé de diatomées. Les 5 points de suivi présentent des compositions floristiques à peu près similaires malgré des situations géographiques assez différentes (estuaire, milieu plus océanique). Dinophysis est la seule algue toxique qui...

Comparisons of european populations of the cerastoderma-glaucum c-lamarcki complex based on reproductive physiology and biochemistry
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Brock, V; Wolowicz, M.
Five European populations of the Cerastoderma glaucum/C. lamarcki complex were studied to elucidate differences between Mediterranean, Western European and Baltic populations: one from the French Mediterranean; two from the west coast of France; one from the Limfjord, Denmark; and one from the metal contaminated Gdansk Bay, Poland. The biochemical tissue composition related to five reproductive stages was analysed, and the results for the five populations were compared. The comparison showed that at similar maturity stages the biochemical composition of the cockle tissue was different for populations from each of the three regions, Northern Europe (region I), the French West coast (region II), and the Western Mediterranean (region III). These differences...

Effects of dissolved mercury on embryogenesis, survival, growth and metamorphosis of Crassostrea gigas oyster larvae
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Beiras, Ricardo; His, Edouard.
The effects of mercury (Hg) concentrations ranging from 0 (control) to 1024 µg 1-1 upon embryogenesis, survival, growth and metamorphosis of Crassostrea gigas (Thunberg) oyster larvae were investigated. Embryogenesis was abnormal in 50 % of the individuals at 11 µg 1-1 . The 48 h LD50 for D·shaped, umbonate and pediveliger larvae were 33, 115 and 200 µg 1-1 respectively. The increase in LD50 was partially explained by the larval weight increase, although weight-specific tolerance to Hg was higher in smaller larvae. Growth, the most sensitive physiological process studied, was significantly retarded at 4 µg 1-1. The metamorphosis rate was significantly reduced when competent pediveligers were exposed to 64 µg 1-1 for 48 h prior to the addition of the...

The effect of stratification on tidal current profiles in a region of fresh-water influence
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Visser, Aw; Souza, Aj; Hessner, K; Simpson, Jh.
Observations of the semi-diurnal tidal current ellipses within the Rhine ROFI are reported. The vertical structure of these tidal ellipses are observed to be significantly different for stratified and well mixed conditions. in particular, during well mixed conditions, tidal currents are essentially rectilinear and directed parallel to the coast. With the onset of stratification, significant cross-shore components, reaching 40% of the magnitude of the along-shore components appear. These components are 180 degrees out of phase from near surface to near-bottom with surface currents rotating anticyclonically, and bottom currents cyclonically. It is proposed that this phenomenon may be explained by a decoupling of the upper and lower portions of the water...

Autores: Fixot, Servane.
Il existe 2 espèces d'huîtres sur nos côtes : Ostrea edulis, l'huître plate et Crassostrea gigas, l'huître creuse. Ces 2 espèces fondent l'essentiel de l'ostréiculture française. Si l'huître creuse a prospéré sur nos côtes depuis 1868 (C.angulata puis par C. gigas à partir de 1973 ), l'huître plate dont la production en 1960 approchait les 15000 à 20000 tonnes a failli disparaître. Deux épizooties ont successivement décimé les bancs d'huîtres plates en Bretagne. Martelia refringens dont la première apparition remonte à 1968 est un parasite de la glande digestive. Un autre parasite, le Bonamia ostreae, apparu en 1979 affecte le système circulatoire de l'huître plate. Cette épizootie a fait chuter la production à moins de 2000 tonnes (Grizel,  1985). Les...

Exoproteolytic activity determined by flow injection analysis: its potential importance for bacterial growth in coastal marine ponds
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Delmas, Daniel; Legrand, Catherine; Bechemin, Christian; Collinot, Cecile.
The measurement of the fluorescent 4-methyl-7-coumarinylamine released from the hydrolysis of a non-fluorescent peptide model substrate by exoproteolytic enzymes has been adapted to flow injection analysis (FIA). FIA allows samples to be processed very quickly (less than 2 min. for triplicate determinations) with good sensitivity (&lt; 0.1 muM) and reproducibility (relative standard deviation &lt; 3 % at the 0.2 muM level). In a coastal marine pond, exoproteolytic activity was closely related to bacterioplankton biomass. The high activity measured in pond water (maximum velocity: V(M) almost-equal-to 1.46 to 2.54 muM.h-1) emphasizes the importance of dissolved protein hydrolysis for bacterial growth and for dissolved organic nitrogen cycling. The mean...

Absorption et régénération de l'azote dans la zone frontale du courant Algérien (Méditerranée Occidentale) : réévaluation de la production nouvelle
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Gentilhomme, V; Raimbault, P.
The uptake and regeneration of four forms of nitrogen NO3-, NO2-, NH4+ and urea) have been studied, in the euphotic layer of a frontal area (Algerian current), in relation with hydrological, chemical and biological parameters. Ln this area vertical stratification is pronounced; a deep chlorophyll maximum at the bottom of the euphotic layer is present. Results show the importance of measuring urea uptake and regeneration in the study of nitrogen cycling, because this component can be regenerated as rapidly as ammonia, and is a source of nitrogen for phytoplankton. Other results show the oxidation of ammonia to nitrate in the euphotic layer, and particularly at the base of this layer. This nitrification is a source of in situ regenerated nitrate, and could...

Diagnostic des pathologies rencontrées chez les mollusques bivalves marins
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Chollet, Bruno.
L'huître creuse, Crassostrea gigas, est aujourd'hui une des espèces de mollusques bivalves marins la plus élevée dans le monde. Cette espèce a été importée du Japon, dans les années 1960-1970, et a remplacé l'huître portugaise, Crassostrea angulata, espéce décimée à cette époque par deux iridoviroses. Suite à la disparition de l'huître portugaise du littoral français et à l'apparition de protozooses (Marteiliose et Bonamiose) chez l'huître plate, Ostrea edulis, une situation de quasi monoélevage de l'huître japonaise s'est installée en France. De ce fait, les risques sur les plans sanitaire et économique sont loin d'être négligeables pour le milieu ostréicole français. En particulier, l'apparition de maladies chez cette espèce pourrait aboutir à une...

Lepidochronological analysis in the mediterranean seagrass posidonia-oceanica state-of-the-art and future-developments
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Pergentmartini, C; Pergent, G.
After blade shedding in the seagrass Posidonia oceanica, leaf sheaths remain attached to the rhizome and can persist for several decades within a ''matte'' They show, according to their insertion rank, cyclical variations in parameters such as thickness and tissue structure. These cycles are always annual, and may be influenced by environmental parameters such as light, temperature or water movement. The study of cyclic changes in Posidonia oceanica sheaths is thus a technique that can be used to investigate past changes in the near-shore environment. By analogy with dendrochronology, this study is termed lepidochronology. A number of applications of lepidochronological analysis have already been successfully tested : (i) Estimation of the growth rate and...

The Conservation of Potential vorticity along Lagrangian Trajectories in Simulations of Eddy-Driven Flows
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Hua, Bach-lien.
The purpose of this note is to investigate the use of Lagrangian potential vorticity conservation as a numerically independent method for checking a posteriori the dynamical consistency of an eddy-resolving GCM simulation. This is performed for a series of simulations with increasing horizontal and vertical resolution. The result that higher vertical modes play a catalytic role in the largest scales of eddy-driven flows is independently confirmed through this Lagrangian test.

The economic development of the French fisheries : the major trends of supply and demand
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Foucault, Francois.
In the context of an economic crisis with the recession in 1993 and a fall-off in demand, the combination, in the beginning of 1993 and 1994, of the following eventsled to a drop in prices which triggered off a social faintness in the French fishing industry, e.g. the adjustment of exchange rates, the reduction in air-freight tariffs, etc... The problem is not so much about the significance of the short term drop  inprices - which is usual at this time of the year- but about the long term trends whichthis sector has been subject to for decades. Beyond the resource's biological constraints, the 1975 difficulties of French fisheries have revealed their vulnerability and dependence on the market of competitive agricultural products, the international market...

Benthic microphytic activity at 2 mediterranean shellfish cultivation sites with reference to benthic fluxes
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Barranguet, C; Alliot, E; Plantecuny, Mr.
Microphytobenthos activity in coastal waters has been studied at two shellfish fanning sites: an oyster farm in Thau lagoon and a mussel farm in Carteau bay (NW Mediterranean coast). In both cases, shellfish are cultivated on ropes hanging from rigid structures (tables) in shallow waters (- 5 m). An ''under table'' station and an ''outside table'' (reference) station were chosen at each site. Oxygen and ammonia fluxes at the water-sediment interface were measured in dark and transparent benthic chambers. Chlorophyll a concentrations were two- to threefold higher in ''under table'' sediments than outside (260 mg Chl a m(-2) under the oyster table, 436 mg Chl a m(-2) under the mussel table in winter). Net oxygen fluxes were negative at all stations, except...

A simulation of nitrogen and phosphorus exchanges for the sediment-water interface is presented, The aim of the sttudy is to understand the dynamic behaviour of an eutrophie coastal lagoon (Thau, France), ln situ experiments were performed to estimate the different pools of nitrogen and phosphorus in the water column and in the sediment. The diffusive fluxes between them were also estimated. A numerical mode1, simulating nitrogen and phosphorus cycles, was developed and calibrated with data recorded .at two seasons (winter and summer). This study leads to the conclusion that is necessary to know the different pools of nitrogen and phosphorus in order to estimate which fraction is bioavailable and the rate of nutrient exchange between sediment and water. It...

Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Robert, Rene; Miner, Philippe; Mazuret, Michel; Connan, Jean-paul.
The influence of density on Patinopecten yessoensis larval development was studied during production of an F2 generation. Setting behaviour of P. yessoensis on PVC removable spat collectors, previously tested with Pecten maximus, was determined. Poor larval growth of P. yessoensis was observed at a larval density of 7 ·ml·1 and post larval settlement occurred mainly on the bottom of the baskets, as has been observed with the king scallop, P. maximus. The PVC collector is not suitable for either species of scallop.

Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Guerault, Daniel; Desaunay, Yves; Beillois, Pierre; Prouzet, Patrick; Martinet, Jean-pierre; Cuende, François - Xavier.
The exploitation of amphihaline species by marine and freshwater commercial fishermen in the Loire estuary in 1989, and by marine commercial fishermen in the Adour estuary from 1985-1991 is described in this study. This fishery employs 320 fishermen and represents a commercial value of 38 million FF. This is mainly due to the exploitation of glass eel, especially in the Loire River, the landings of which have decreased alarmingly. In the Adour River, the diversity of the exploited species and the total commercial value of drift gillnet catches - on the average 43% - in this fishery are high. The landings of migratory salmonid species are high and they may attain 25% of the total commercial value. This study emphasizes the uniqueness, the socio-economic...

Cycle de développement d'une population intertidale de Nereis virens (Polychaeta Nereidae) de l'estuaire maritime du Saint-Laurent
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Desrosiers, G; Caron, A; Olivier, M; Miron, G.
An intensive study was conducted from 1986 to 1988 to schematize the life history of the intertidal population of the annelid Nereis virens. Spawning occurred between late April and early June on the south shore of the Lower St. Lawrence estuary. Then, epitokous males leave the sediment and move towards female burrows, displaying heteronereid movements before releasing gametes. Femalesremain in their burrow and release oocytes which adhere to sediment surface where they will be fertilized. All mature individuals die after spawning. Larvae go through conspicuous changes during suprabenthic, pelagic and benthic development (monotrochophore, trochophore, metatrochophore, nectochaete). Settlement occurs in the upper intertidal zone and depends essentially on...

During a fortnightly tidal cycle, a Mytilus edulis population was submitted to natural food conditions in the bay of Marennes-Oléron. During 4 tidal cycles, in vivo continuous measurements of turbidity and fluorescence were recorded to study the evolution of Total Particulate Matter (TPM), phaeopigments and chlorophyll-a concentrations. Turbidity in the water column is clearly influenced by resuspension of sediment. Degradated cells of phytoplankton were associated with sediments, involving strong correlation between phaeopigments and turbidity. High values of chlorophyll-a were encountered during neap tides when turbidity was low. No relation with resuspension processes were observed.  No effect of fortnightly variability on retention was observed by...

Quantitative sampling of soft-bottom macroepifauna for assessing the benthic system in the bay of brest (france)
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Jean, Frederic; Hilly, C.
Macroepifauna of mixed sediments was quantitatively studied at three stations in the Bay of Brest. Samples were collected with the quantitative video dredge Aquareve II. Sampling performance varied from 6.1 to 55.6 m2 according to the mesh diameter of the net (10, 40, and 70 mm) and the quality and quantity of the hard structures lying on the bottom. The efficiency of the different sampling options is tested. The ecological analysis shows differences between epifaunal assemblages, which are mainly explained by the characteristics of the ruggedness in each station. Ruggedness is defined in terms of quality and quantity of hard structures (pebbles, gravel, shells, coraline algae and macroalgae) lying on the sediment surface. Hard substrates act as...

Phytoplankton fluorescence and deep chlorophyll maxima in the northeastern mediterranean
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Yilmaz, A; Ediger, D; Basturk, O; Tugrul, S.
Two expeditions in the northeastern Mediterranean by the R/V Bilim (in July 1988 and March 1989) scanned an area of about 3 x 10(5) km2 to determine, in situ, the relative fluorescence intensities of the upper layer waters. The in situ fluorescence intensities exhibited a fair correlation with the discrete chlorophyll-a concentrations when the concentrations exceeded 0.1 mug/L. Light intensities indicated that the euphotic zone had an average thickness of 100 m in the open waters. The deep chlorophyll-a maxima (DCM) at the bottom of the euphotic zone usually coincided with the maxima observed by in situ fluorometry and were a prevalent characteristic of the oligotrophic northeastern Mediterranean. The formation, maintenance and location of the DCM were...

Etude Sédimentaire Appliquée à l'Aquaculture pour Cinq Estrans de Bretagne Sud (Morbihan et Loire Atlantique).
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Lemoine, Gérard.
Within the national molluscan monitoring network, a sedimentary study was carried out on five experimental sites located in southern Brittany (i.e., from Etel to Pen-Bé rivers). The study aimed to specify sediment integrating characteristics with regards to hydrobiological variables. Moreover, interactions between sediment and water column characteristics were specified. It appears that this approach is likely unappropriate to characterize interdical rearing area productivity. However, this approach can support the site evaluation on a long term basis to sustain shellfish culture management. This would require additional study to assess sediment reactivity to abnormal events like drastic salinity decrease.

Autores: Merceron, Michel; Gaffet, Jean-dominique.
Current recordings were performed near the middle of the great breakwater of Cherbourg ("Grande Digue", inner side) during two months of the 1993 summer. The data show that, in this site, the currents drive mostly westwards. They are driving eastwards only during the first half of flood. In the tidal cycle, there is only one current slack, at law tide. The most important velocities are observed during the high tides : 0.5 to 0.6 m.s-1• The fish net pens, which are located there, tend to speed up the undemeath currents and, thus, contribute to scatter the farm effluents. The temperature and salinity records are also displayed. _

Gestion de l'eau douce et conchyliculture en Charente-Maritime
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Masson, Daniel.
The wetlands of Charente-Maritime represent 100,000 ha and are classified in three categories: flooded marshland valleys, freshwater marshes (farmed land) and coastal salt marshes (traditional and modern shellfish farms). The economic character of the latter two categories gives rise to conflicts of use. Both the agricultural and aquacultural professions are particularly sensitive to these conflicts due to the difficult economic times they are currently experiencing. The main issue is freshwater management, in both its qualitative and quantitative aspects. Charente-Maritime climate is characterised by rainy winters and dry summers and all players need water (or wish to evacuate it) during the same periods. It is thus necessary to mediate disputes or even...

The impact of harmful algal blooms on finfish. Mortality, pathology and toxicology
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Brusle, Jacques.
Many algal blooms ("red tides" or "brown tides") may be noxious for finfish, either causing anoxia through decay process, clogging the gills or producing specific toxins. Since the 1970's, records of the incidence of injury and mortality to wild and cultured fish due to toxic phytoplankton have increased. It was even demonstrated that toxic algal blooms are spreading in intensity, geographic distribution and number of algal species involved. Thus, algal blooms are becoming one of the major economic threat to fisheries and fish culture industry. This review deals with the literature available (more than 250 references) on the occurrence of fish kills associated with worldwide algal blooms. Their negative effects on fish that result in economic losses are...

Growth and proximate biochemical composition of the American oyster Crassostrea virginica were studied in the Patuxent river (Maryland), located in the middle reach of the Chesapeake bay (U.S.A.). The effects of stocking densities and environmental variables (depth, temperature) were examined in 1989-1990 on oyster population by using off-bottom culture. No significant density effect was observed on the shell growth, which is described by using a seasonally oscillating function. In contrast, the meat growth and the proximate biochemical composition were bath affected by the stacking density and the depth location. The variability of the resulting effects was observed based on a seasonal trend. Different hypothesis mainly related tO environmental conditions...

Autores: Le Traon, Pierre-yves; Demey, P.
Two years of Geosat data (November 1986 to December 1988) for the Azores-Madeira region of the North Atlantic are analyzed. The objective is to study the eddy field associated with the terminal retroflection of the Azores current. The rms variability of sea level anomaly is 4 to 8 cm, with maximum values between 33-degrees and 35-degrees-N being associated with the Azores current and located on its northern flank. Higher energy is observed during winter and during the year November 1987 to November 1988. Analysis of velocities at crossovers reveals anisotropy with larger meridional velocity variances. This is the signature of meanders and/or eddies elongated in the north-south direction. The eddy-mean flow interaction is studied through the analysis of the...

Trace elements (As, Cd, Cu, Hg, Se and Zn) were determined in liver and kidney of pilot whales Globicephala melas Traill, 1809 collected from 7 schools caught at different seasons around the Faroe Islands. These and other biological data at our disposal enabled us to confirm and to define more accurately the relations shown previously between age, sex and trace element concentrations in marine mammals. The most striking features were: (1) the elevated levels of Cd and Hg in pilot whales compared to other marine mammals and to minimum adverse-effect levels established for humans; (2) the biocumulative behaviour of Cd and Hg; (3) the high correlations between Hg and Se, predominantly influenced by age; and (4) the high correlations between Cd and Zn, the...

The yields, compared to those of commercial fishermen, were medium or good for Plesionika...

Decline of the Chesapeake Bay oyster population : a century of habitat destruction and overfishing
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Rothschild, Bj; Ault, Js; Goulletquer, Philippe; Heral, Maurice.
The oyster population in the Maryland portion ot Chesapeake Bay, USA, has declined by more than 50-Iold since the early part of this century. The paper presents evidence that the mechanical destruction of habitat and stock over fishing have been important factors in the decline, even thouqh it is commonly thought that 'water quality' and, more recently, oyster diseases are critical. Quantitative analyses show that the long-term decline 01 oysters largely resuIts from habitat loss associated with intense fishing pressure early in this century and stock over fishing from early in the century throuqh recent limes. Furthermore, the major ecological effects on Chesapeake Bay occurred weIl betore World War II, before industrialization and the reported prevalence...

Possible sources and mechanisms of manganese enrichment in the deep-sea sediments of the marmara trough depressions (ne-mediterranean, turkey)
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Ergin, M.
Enrichment of Mn in deep-water relative to shallow-water sediments in the Marmara Basin was investigated using earlier metal data and some geochemical information from other similar marine regions on a comparative basis. Deep-water (1152-1276 m) sediments from the three depressions located along the Marmara Trough of the seismically-active North Anatolian Fault Zone contained much higher Mn concentrations (&lt; 6355 ppm; over 10 600 ppm in some core horizons; on a carbonate-free basis) than those from the surrounding shallow-water (54-855 m) sediments (307-2059 ppm Mn on a carbonate-free basis). Cu and Ni showed the same trend altough their concentrations were small. On the other hand, the sediments were not enriched in other metals (Fe, Co). The low...

Three biomarkers [ethoxyresorufm-o-deethylase (EROD), DNA adducts and micronuclei (MN) were studied for biomonitoring applications along French coasts. EROD was developed at an experirnental stage in two pilot sites, Seine Bay and Fos sur Mer, using the dab (Limanda limanda), dragon et (Callionymus lyra), red mullet (Mullus barbatus) and comber (Serranus hepatus) as target species. Higbest EROD activity was observed in the subestuarial part of Seine Bay and at the stations closest to sources of pollution from Cortiou and Fos sur Mer. The suitable number of fish for detection of a significant difference between two EROD activities was deterrnined as a function of sampling variance and a preselected statistical power. A preliminary study on hepatocytes in a...

Autores: Barille, Laurent; Bougrier, Serge; Geairon, Philippe; Robert, Jean-michel.
The influence on the feeding physiology (clearance, filtration, ingestion, absorption) of the Japanese oyster Crassostrea gigas of low concentrations of suspended particulate matter (SPM ranging from 2 to 20 mg.l-l) and high food quality (mean organic fraction =54 %) was studied in the laboratory. Experimental diets were made up with three strains of the "blue diatom" Haslea ostrearia, which is responsible of the greening of oyster-ponds. The strains were characterized by different sizes (48, 65 and 98 µm respectively) but possessed the same density and biochemical composition. Clearance rate was found constant at 2.2 1.h(-l).g-l dry weight and therefore was not influenced by increasing seston load. Pseudofaeces production was observed for SPM...

Autores: Martineu, Pierre.
Les populations naturelles sont soumises à un ensemble de contraintes écologiques dont on distingue deux composantes : - les contraintes biotiques, qui résultent de l'interaction avec d'autres organismes : compétition, prédation; - les contraintes abiotiques, qui traduisent l'action des facteurs physiques : température, circulation hydrodynamique, ... L'action conjuguée de ces contraintes conduit la population dans un domaine de fonctionnement dont on peut faire une lecture démographique ou évolutive. D'un point de vue démographique, le domaine de fonctionnement de la population concerne l'évolution de la structure des effectifs: répartition dans l'espace, dans les stades de développement, les classes d'états individuels.

Estimation des biomasses de moules (Mytilus edulis L.) en élevage dans les bouchots du Pertuis Breton - Evolution entre 1988 et 1993
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Dardignac-corbeil, Marie-jose.
The biomass of the cultivated mussels has been estimated every year in the Pertuis Breton dulring the period 1988-1993. The method used is first recalled, then the question of the biomass trends during spring -i.e. during the sampling period- is discussed. Based on the results, it appears that the mussel volume starts decreasing in 1990 to reach a minimum in 1991. A slight increase is observed in 1992 but no further improvement in 1993. The factors possibly related to this evolution are finally discussed.

Water masses and phytoplankton biomass distribution during summer in the weddell sea marginal ice-zone
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Perez, Ff; Tokarczyk, R; Figueiras, Fg; Rios, Af.
This study - carried out between the Elephant and the Orkney islands - showed that spatial variability in the marginal ice-edge zone (MIZ) was greater than that found in open sea. Salinity and silicate contents point to the existence of two fronts: the first - near Elephant Island - separates the Surface Antarctic Water coming from Drake Passage from the winter water originating in the Weddell Sea. This water is characterized by its high concentrations of nitrate (&gt; 30 mu M) and silicates (&gt; 80 mu M). The second front - near the South Orkney Islands undergoes the influence by a less saline water lens (&lt; 34 %), poor in nutrients (N-NO3 &lt; 24 mu M) and rich in chlorophyll (&gt; 3.5 mg Chl a 1(-1)). Water masses circulation reveals the existence of...

Des essais de toxicité aigue font toutefois apparaître des seuils de toxicité inférieurs au mg/l notamment chez les crustacés qui semblent les organismes les plus sensibles à ce métal. A des concentrations de l'ordre de 30 à 100µg/l, le nickel exerce des effets inhibiteurs sur la reproduction et le développement embryonnaire de plusieurs espèces d'invertebrés.

This study concerns numerical simulations carried out following the elaboration of an oceanological multidomain model. These simulations demonstrate the value of such a model for physical oceanography. A simplified, two-domain version of the multidomain model is presented. It is based on a computer code which solves the Navier-Stokes and temperature equations in the three dimensions of space for an incompressible fluid in accordance with the hydrostatic approximation and Boussinesq's assumption. This model permits a zoom on a specific region of the spatial domain, where the primitive equations are solved, with a mesh refinement, in order to correct by feedback the global numerical solution. It includes a nested procedure which manages the resolution of the...

The Normandy region is presently a leading shellfish rearing area in France yielding 35,000 metric tons of oysters C. gigas and Il,000 metric tons of mussels M. edulis on a yearly basis. Preliminary studies were initiated in 1989, 1991 and 1992 to develop the sampling strategy for cultured mussel stock assessment. Comprehensive mussel stock assessment and concomitant growth monitoring were carried out in 1993 to study mussel population and optimize overall s1l1ellfish culture management.  A three-stage cluster sampling strategy combined with stratification was tested on the 278 kms 'bouchot' type culture with a sampling effort of 275 units. Stratification was based upon two criteria including geographical sector and tidal level. Overall biomass was...

Pecten maximus larvae exhibit amylase as a main digestive enzyme indicating the possibility of starch hydrolysis. The food value of Rhodomonas salina and Porphyridium cruentum, both rich in starch, on the development of Pecten maximus larvae was investigated. The larval development was studied by means of an image analysis technique and epifluorescence microscopy was used for detecting ingestion and digestion of each phytoplankton species. The biochemical contents of algae and larvae were also assessed. The best growth of Pecten maximus larvae was observed when fed with the mixture PTS (plurispecific control). No growth was observed for larvae fed with Porphyridium cruentum of which most of the population died on day 16 (90%). This algal species was...

In these increasingly cost-conscious times, tax-payers are entitled to ask whether their national environmental research and monitoring programmes are delivering value for money, and it is understandable and right that they should. More people than ever are now inclined to enquire as to the quality of the results of chemical analysis before using them for their intended purpose, and 'Quality Assurance' is the phrase on everyone's lips. It is no secret that marine chemists have generated their share of random numbers in the past. That said, sorne of the techniques in use in environmental analysis twenty years ago were not sufficiently well-developed for their intended task ; for example, the role of contamination and its influence on these techniques was...

They affect various littoral sites and belong to diverse species (Ulva, Enteromorpha and especially Cladophora). In 1990, on the North Brittany shore, more than 80 000 m3 ulvas have been mechanically removed by affected communities. Up until recently, the Arcachon basin escaped from such phenomenon, even if the diversity and quantity of algae found there had already undergone increasing periods in the past. However, the first algae proliferations only started in the 80's, which scale was large enough to be a nuisance to all activities taking place in the basin.  At first (starting in1982), those proliferations were...

Instability of wind-forced inertial oscillations
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Treguier, Anne-marie; Klein, Patrice.
An instability mechanism that can amplify wind-forced inertial oscillations in the upper ocean is investigated. This forced instability happens because of the phase relationship between the mixed-layer depth and the surface current. It allows the inertial oscillations propagating against the wind to extract energy from it and amplify. The key ingredients for the instability to work are (a) a non-zero mean wind stress, (b) a spatial variability of the oscillations in the direction of the wind stress. The amplification is demonstrated using a simple shallow-water model in a few situations: the dispersion of a localized disturbance with steady and time-varying wind forcing, generation of inertial waves at a coast, and spatial variability induced by mesoscale...

Western boundary current variability off french-guiana as observed from moored current measurements
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Colin, C; Bourles, B; Chuchla, R; Dangu, F.
Moored current measurements carried out from 31 March 1990 to 15 September 1991 in two stages at a point (near 6 degrees N) located over the mid-continental slope off French Guiana are presented. Six current meters were positioned between 200 and 2700 m depth. Upper level mean current data showed a northwestward flowing North Brazil Current (NBC) with mean velocity values decreasing from 10 cm/s in the range 200-250 m to almost zero at 800 m depth, the level of the Antarctic Intermediate Waters. In the range 500-800 m, the current reversed in spring in the presence of the southeastward Western Boundary Under Current (WBUC); the mean velocity from February to June 1991 is around 2 cm/s. Deep currents over the continental rise show a strong southeastward...

Autores: Fouquet, Yves; Auzende, Jean-marie; Ballu, V; Batiza, R; Bideau, Daniel; Cormier, Mh; Geistdoerfer, P; Lagabrielle, Yves; Sinton, J; Spadea, P.
69 new hydrothermal sites were discovered during the Naudur diving cruise. Dives were conducted between 17 degrees 5 and 18 degrees 40'5 on four segments showing marked contrast in morphology, volcanic, tectonic and hydrothermal activity. At 17 degrees 10'5, 17 degrees 25'5 and 18 degrees 37'5 the ridge has a dome shaped cross-section and is dominated by very active volcanic activity. Early widespread low temperature (&lt;50 degrees C) diffuse hydrothermal discharge is followed by focused high temperature black smokers. At 18 degrees 15'S tectonic activity is dominant, no recent lava was observed, and only two of the 20 hydrothermal sites are active. At 18 degrees 32'5 recent lava representing a new volcanic episode partly covers the bottom of the graben....

NAUDUR explorers discover recent volcanic activity along the East Pacific Rise
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Auzende, Jean-marie; Sinton, John.
Surveying an ultra‐fast spreading ridge along the East Pacific Rise (EPR), explorers aboard the submersible Nautile examined features such as lava pillows and tubes, sulfide chimneys, black smokers, hot shimmering waters, and colonies of animals living in hydrothermal vents to learn more about the processes of accretion and tectonics on the ocean floor. Taken together, the observations of the EPR between 17°S and 19°S from the 1993 NAUDUR cruise (a French acronym for Nautile on Ultra‐fast Ridge) indicate recent volcanic eruptions occurring as frequently as every few years. The NAUDUR cruise was designed to study the interaction between magmatic, tectonic, and hydrothermal processes at an ultra‐fast spreading axis of the EPR. Researchers performing twenty...

Structural and biochemical characteristics in adult scallop shells
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Devauchelle, Nicole; Cuif, Jean Pierre; Larvor, H; Larzul,.
This paper presents results of studies carried out on the microstructure, composition of organic matter and amino acids in abnormal shells of adult Pecten maximus. Results indicate that abnormal P. maximus shells can have two types of brown material on the inner layer of the valves. Brown calcified areas can be present and they have abnormal crystals on the internal foliated layer of the shell. An index (MIBC) was developed to describe this type of abnormality that depended on the extent of the brown areas. The other type abnormality had brown material consisting of uncalcified membranes that were embedded in mud tubes made by Polydora sp. worms. The amino acid composition of these two materials was completely different. When compared to white (normal)...

Les départements et territoires d'outre mer sont généralement l'objet d'enjeux économiques importants, et de conflits d'activités liés au développement touristique, aquacole, agricole et industriel. Les études font généralement état d'une lente dégradation de l'environnement marin avec diminution des coraux et de la faune associée, au profit d'une augmentation de la couverture algale. On constate parfois un envasement ou un ensablement des sites, la présence dans l'eau de polluants organiques, dont des pesticides, des métaux ainsi que des microorganismes d'origine fécale. En Martinique, ce dernier aspect, lié à l'assainissement des zones rurales, urbaines et touristiques est actuellement considéré comme une préoccupation majeure pour les prochaines années....

Lactic acid bacteria increase the resistance of turbot larvae, Scophthalmus maximus, against pathogenic vibrio
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Gatesoupe, Fj.
Characteristics of Lactic Acid Bacteria (LAB) isolated from rotifers, Brachionus plicatilis, resembled those of Lactobacillus plantarum or Carnobacterium sp. It was investigated whether the artificial maintenance of a high concentration of LAB in rotifers might increase their dietary value for turbot larvae, particularly when the fish were infected with pathogenic Vibrio sp. One LAB strain was cultivated, then introduced daily into the enrichment medium of rotifers. In this way, LAB were retrieved in large amounts in turbot, and a significant limitation of larval mortality rate was observed when turbot were challenged with pathogenic vibrio at day 9. The inoculum concentration of LAB had a decisive effect on survival rate, and the optimum was between 10(7)...

Small-scale melt processes governing the flushing of nutrients from a first-year sea-ice, Hudson-Bay, canada
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Hudier, E; Ingram, G.
This work formed part of a multi disciplinary research programme conducted 25 km offshore of Kuujjuarapik in southeastern Hudson Bay (Canadian Arctic). Large differences in salinity and nutrient concentration between brine, ice and under-ice surface water were used to study the different phases observed during the period of melt initiation. We present a discussion of processes governing the flushing of brine and the development of a melt layer below first-year sea ice. Phosphate, nitrate + nitrite and silicic acid distributions within the first 30 cm below the ice are described. Three distinct steps were observed during the melt initiation: a phase of brine rejection; a phase of flushing associated with the development of a buoyant melt layer rich in...

Induced triploidy in the European clam, Ruditapes decussatus (L.) and performance of triploid larvae
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Gerard, Andre; Naciri, Yamama; Noiret, Christophe; Ledu, Christophe; Peignon, Jean-marie.
For the first time, effective treatments using cytochalasin B were developed to induce triploidy in the European clam, Ruditapes decussatus (L.). The percentage of triploid embrios was assessed by karyological or image analysis. Two treatments (O.5 or 1 mg of cytochasin B (CB per ml of dimethylsulfoxide in 1 l of sea water) were applied at different times after fertilization (10 to 25 mn), for two different periods (15 and 20 min). Best results were obtained for a CB concentration of 1 mg/l. When treatment was applied 15 min after fertilization for a 20 min period, 94% and 95% of triploid embryos were obtained in two repeated experiments. At metamorphosis, the treated larvae appeared to be no smaller than the control larvae in all experiments. Thowever, in...

Quantitative estimation of biodiffusive and bioadvective sediment mixing - in-situ experimental approach
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Gerino, M; Stora, G; Durbec, Jp.
An in situ experiment was conducted over a short period of time to quantify bioturbation with a pulse input of particulate and conservative tracers, the luminophores. Application of a biodiffusive and bioadvective model gives estimations of the mean biodiffusive mixing rate (D = 4.3 +/- 2.8 cm2.y(-1)) and the mean vertical transport rate (V = 27.5 +/- 15.1 cm.y(-1)). The heterogeneity of the results from every core is attributed to the different composition of the benthic community in each of them, and provides evidence of the horizontal variability of the bioturbation measurements on the same site. Only experiments of brief duration permit assessment of the bioadvective and non-local mixing events that superimpose biodiffusion effects in most of the...

We measured the utilization (i.e., ingestion and absorption) rates of the detritus derived from three microphytes (Nitzschia acicularis, Nitzschia sp., and Pavlova lutheri) by the deposit-feeding bivalve Abra ovata. The labelling procedure consisted in labelling Live microphytes with C-14 sodium bicarbonate. The cultures were then rinsed, frozen, and freeze-dried. The analysis of temporal changes in the distribution of radioactivity within the control chambers showed: (I) a significant production of (CO2)-C-14 and (2) a rapid transfer of radioactivity from POM (i.e., detritus) to DOM. Modelling of the exchanges of radioactivity between compartments within the control chambers permitted quantification of these two processes, and computation of the initial...

L'aménagement du littoral prend une acuité particulière dans les estuaires qui ont toujours été des zones d'intense activité maritime. Des ports se sont installés très tôt à la croisée des routes et de la voie d'eau, là où le flot de marée permet une pénétration profonde de la navigation à l'intérieur des terres. Rouen, Nantes, Bordeaux sont ainsi établis sur les grands fleuves. Au fur et à mesure de l'expansion du commerce maritime, la taille des bateaux a augmenté et, avec elle, le tirant d'eau. Il a fallu, pour assurer la remonté de navires de plus en plus gros, lutter contre l'envasement, creuser les chenaux pour maintenir les profondeurs. Les aménagements n'ont pu suivre l'évolution récente de la taille et du tirant d'eau des navires et les activités...

Adaptation of digestive enzymes to dietary protein, carbohydrate and fibre levels and influence of protein and carbohydrate quality in Penaeus vannamei larvae (Crustacea, Decapoda)
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Le Moullac, Gilles; Van Wormhoudt, A; Aquacop, Aquacop.
Activity of digestive enzymes (trypsin, chymotrypsin and amylase) was studied in relation with food in Penaeus vannamei larvae first stages. Microparticles containing casein involved the decrease of soluble protein content and enzyme activities. Specific trypsin activity but not chymotrypsin was correlated (p&lt;1%) to casein level between 10 and 60% in microparticles. Cellulose fibres in food seemed to have little effect on digestive enzymes. Starch, between 1 and 20% in microparticles, had no influence on specific amylase activity. The effect of different feeding conditions were also tested on growth. No clear relationship between growth and enzyme is established since only trypsin is concerned in the case of a casein dose effect in the food. The protein...

Bar codes in fisheries research: development of the "ichthyometer"
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Morizur, Yvon; Ogor, Andre; Lespagnol, Patrick.
A patent was registered in 1991 for using bar codes to make up fish measuring board. Collection of data such as the length of the captured fish and sometimes their ages are required in order to manage fishery resources. It is a time-consuming operation as this work is usually carried out throughout the year for each species. The computerization of this phase has been the subject of much research work. Electronic fish measuring boards have been developed in Scotland, Canada, and Spain but they have not spread for a number of reasons. Going beyond these developments, IFREMER designed a more efficient and new open-ended fish measuring system - the ichthyometer - which features higher flexibility by using the bar code principle

Tectonique compressive cénozoique sur les rides de Fairway et Lord Howe, entre Nouvelle-Calédonie et Australie
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Lafoy, Yves; Pelletier, Bernard; Auzende, Jean-marie; Missegue, F; Mollard, L.
The new bathymetric, magnetic and mainly seismic data acquired during the Zoesis cruise, reveal the presence of compressional features in the ''Fairway Ridge-Fairway Basin-Lord Howe Rise (northern part)'' area, west of New Caledonia. The compressive strain is especially responsible for the formation of the Fairway Ridge. The compression is emphasized by a regional unconformity that could be dated late Eocene, according to DSDP data in the area, and therefore synchronous with the late Eocene obduction of the New Caledonia ophiolites. The westward extension of the late Eocene compressive strain in the New Caledonia area is more developed than previously thought.

Tandis que l'informel a pendant longtemps été considéré comme une déviance ou une survivance de mécanismes « traditionnels », il est à présent de plus en plus envisagé de laisser s'étendre le champ de son intervention, pour les possibilités intéressantes qu'il ouvre en matière de création d'emploi et de dynamisation du développement. Ainsi, les institutions internationales qui, comme le Bureau international du travail, s'étaient attachées à tenter d'évaluer le phénomène, mettent à présent en oeuvre des politiques qui visent à sa promotion. Cette évolution paraît paradoxale puisqu'elle se fonde sur la reconnaissance par l'État d'un secteur dont le non-enregistrement est à la fois un facteur de dynamique et le seul critère commun de spécification (CHARMES,...

Les dinophycées pélagiques et benthiques du Golfe de Gascogne sud de la Bretagne à Arcachon
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Paulmier, Gerard.
Les microphytes planctoniques et benthiques du Golfe de Gascogne sont relativement diversifiés. Cette diversification est probablement en rapport avec la situation hydrologique particulière de cette région enrichie par des mélanges de masses d'eau de diverses origines et par des apports continentaux importants. Dans ce contexte, les dinophycées sont nombreuses et variées et occupent toutes les niches écologiques. 230 taxons ont été répertoriés. Quelques espèces sont connues pour provoquer périodiquement des colorations de la mer "eaux rouges" et quelques-unes sont maintenant redoutées pour leur toxicité.

Skewness of the generalized centrifugal force divergence for a joint normal distribution of strain and vorticity components
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Hua, Bach-lien.
This note attempts to connect the skewness of the probability distribution function (PDF) of pressure, which is commonly observed in two-dimensional turbulence, to differences in the geometry of the strain and vorticity fields. This paper illustrates analytically the respective roles of strain and vorticity in shaping the PDF of pressure, in the particular case of a joint normal distribution of velocity gradients. The latter assumption is not valid in general in direct numerical simulations (DNS) of two-dimensional turbulence but may apply to geostrophic turbulence in presence of a differential rotation (beta effect). In essence, minus the Laplacian of pressure is the difference of squared strain and vorticity, a quantity which is named the generalized...

Impact de l'aquaculture marine sur l'environnement : aspects juridiques et économiques
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Paquotte, Philippe.
Aquaculture is an economic activity which is characterised by a great dependence on environmental conditions. Therefore aquaculture development is subdued to institutional context which defines the rules for use and conservation of the environment. This paper analyses the impact of marine environment regulations on economic operating of aquaculture enterprises and on industrial dynamics. Because aquaculture enterprises use a collective good, an economic approach of aquaculture has to take into account not only the relations between enterprises and environment, but also the relations between the enterprises themselves, through production externalities. In this study, several economic tools are considered in order to incite enterprises to integrate pad of...

Equilibrium temperature as a parameter for estimating the net heat-flux at the air-sea interface in the central red-sea
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Ahmad, F; Sultan, Sar.
The net rate of heat exchange at the water surface in the central Red Sea is calculated with reference to the equilibrium temperature and the thermal exchange coefficient, both of which depend on meteorological variables. The monthly means of this exchange agree well with the values computed on the basis of heat balance processes which include sensible, evaporative and radiative heat fluxes.

Le milieu marin est continuellement alimenté en matières organiques et minérales d'origine naturelle ou anthropique, apportées en solution, sous forme colloïdale ou particulaire. Ces matières, dont certaines contiennent des contaminants sont, dans l'ensemble, très rapidement incorporées aux sédiments par décantation, précipitation, ou adsorption. De ce fait, les sédiments estuariens et côtiers constituent le plus vaste dépôt de contaminants et une source importante de contamination potentielle pour le milieu marin ( HORZEMPA et Di TORO, 1983). ll est donc nécessaire, pour gérer au mieux l'environnement côtier, de connaître le contenu en micropolluants des sédiments ainsi que les principaux processus qui régissent le "devenir" de ces contaminants dans le...

Modifications des communautés algales méditerranéennes en présence de l'algue envahissante Caulerpa taxifolio (Vahl) C.Agardh
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Verlaque, M; Fritayre, P.
The introduced invasive alga Caulerpa taxifolia is altering the appearance of algal communities in the western Mediterranean sea. A detailed study of two similar areas, one with and one without Caulerpa taxifolia, shows a drastic impoverishment of the algal community where Caulerpa has invaded. Many of the normally expected species have disappeared; firstly the fleshy species with their epiphytes, then the filamentous species and finally the crustose algae. The most marked effect is seen at the end of the summer and autumn when the Caulerpa reaches its maximum size. Hardly any epiflora is found on the Caulerpa except in spring when old branches with epiphytes predominate. In the Alpes-Maritimes region, species-poor meadows of Caulerpa taxifolia are...

Oxygen and carbon dioxide fluxes at the water-sediment interface of a tropical lagoon
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Boucher, Guy; Clavier, Jacques; Garrigue, Claire.
Oxygen demand, carbon dioxide release and total alkalinity shift were calculated from changes in oxygen, pH and total alkalinity produced by bottom dark incubations at the water-sediment interface of the 3 bottom types identified in a southwest lagoon in New Caledonia. Total sediment oxygen demand (AO?) was corrected from nonbioloyical oxygen demand (NBOD) In order to obtain the apparent biological activity (AOlO)T.o tal carbon dioxide flux (AC02)w as corrected from total alkalinity shift in order to estimate organic carbon processes. The resulting mean carbon dioxide flux (ACOzO= 2.58 mm01 m-' h-', SE = 0.12) exceeded biological oxygen demand (AO," = 1.60 mm01 m-' h-', SE = 0.08).

Autores: Gerard, Andre; Naciri, Yamama; Peignon, Jean-marie; Ledu, Christophe; Phelipot, Pascal; Noiret, Christophe; Peudenier, Isabelle; Grizel, Henri.
For determination of ploidy levels in bivalves,  three techniques are now routinely used: karyological determination. microfluorimetry and flow cytometry. This paper proposes an alternative technique which is based on determination of the optical density (OD) of stained nuclei using image analysis. A karyological and image analysis comparative experiment conducted on juveniles of Crassostrea gigas (Thunberg) and Ruditapes philippinarum (Adam &amp; Reeve) is described and highlights the advantages of the image analysis technique. Initially developed on C. gigas and R. philippinarum, the image analysis method was easily extended to other bivalve species and to different developmental stages, as demonstrated by two experiments conducted on Ostrea edulis (L.)....

Autores: Francour, P.
From July 1988 to September 1992, Scuba divers used a non-destructive sampling method to study the fish communities of rocks and Posidonia oceanica seagrass beds, in Scandola Marine Reserve. Sites were established in the integral reserve (protection of the marine environment), in the non-integral reserve (partial protection) and outside the reserve (no protection). Average density and biomass of the sampled population in P. oceanica seagrass beds showed no significant difference between the sites in the integral reserve and the others. Only the integrally-protected shallow and deep water zones showed considerably reduced seasonal variations. For rocky substrata, the integral reserve site demonstrated higher density and biomass than the other sites. The...

The sterolic composition of Caulerpa taxifolia (Vahl) C. Agardh (Ulvophyceae), a green alga recently introduced in the Mediterranean sea, is characterized by the presence of a major sterol, clionasterol, with small amounts of cholesterol, 24-methyl-cholesterol, 24-methylene-cholesterol, 24Z-ethylidene-cholesterol. The clionasterol present in some other Caulerpa species seems to be a chemotaxonomic marker in the genus Caulerpa.

L'élimination de la crépidule est une préoccupation majeure de la part de nombreux ostréiculteurs. Que leurs concessions soient sous 10 mètres d'eau, comme à Cancale, ou sur l'estran, elles sont de plus en plus envahies par ce gastéropode proliférant. Les professionnels sont obligés de procéder à de fréquents nettoyages. Le problème qui se pose alors est le devenir du produit ainsi débarqué. Très peu de solutions intéressantes sont actuellement proposées, en dehors de l'écrasement et de l'enfouissement dans les terrains agricoles, pour la culture des primeurs comme cela se pratique au Vivier-sur-Mer.

Autores: Maurice, L.
The organic matter trapped in the turbidity maximum zone of the Loire estuary, as a support of bacterial activity, constitutes a basic element in the biogeochemical cycle which permits us to understand the causes of the anoxia observed in September. Measurements of the main physical and chemical parameters and of bacterial biomass were carried out in the water column and in the fluid mud in September 1990 and 1991. The anaerobic fluid mud is presumed to be the centre of fermentation and/or hydrolysis processes; the formation rate of dissolved organic carbon (DOC) in this layer reaches 3 g C.m(-3).d(-1). When particles are suspended in the water column, the organic products formed in the fluid mud are integrated into the aerobic metabolic cycle and...

Croissance et mortalite du petoncle noir Chlamys varia dans le bassin d'Arcachon, France
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Trut, Gilles; Robert, Rene; Laborde, Jean-louis.
Until 1960, the Black scallop Chlamys varia was relatively abundant along the French Atlantic coasts. Today most of these natural beds have disappeared. Because mollusc hatchery and nursery techniques have been mastered, the reintroduction of this species, under control, was carried out in several areas and particularly in the bay of Arcachon, from 1989 to 1992. Good results were obtained in hatchery and nursery but the development of the juveniles in the natural fields was poor. The growth of Chlamys varia was satisfactory but heavy mortalities were rapidly recorded which could not be related to the hydrobiological conditions. This species seems to be very sensitive to short emersion and removal operations which are incompatible with aquaculture processes.

Global oceanic and atmospheric oxygen stability considered in relation to the carbon-cycle and to different time scales
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Duursma, Ek; Boisson, Mprm.
This paper constitutes an overview and synthesis concerning atmospheric and oceanic oxygen and related carbon dioxide, particular attention being paid to potential regulation mechanisms on different time scales. The world atmospheric oxygen reserve is remarkably large, so that a lack of oxygen will not easily occur, whether in confined spaces or in major conurbations. On ''short'' scales, measured in hundreds or thousands of years, feedback processes with regard to oxygen regulation, solely based on atmospheric oxygen variations, would have to be so highly sensitive as to be barely conceivable Only oxygen in the oceans can vary between zero and about twice the saturation - a fact which suggests that here, at least potentially, there exist possibilities for...

Causes of decline of oyster production (Crassostrea virginica) in the Maryland portion of the Chesapeake Bay : a literature study
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Goulletquer, Philippe; Heral, Maurice; Rotschild, Brian.
The historical landings of Eastern oyster Crassostrea virginica are described for the Maryland part of the Chesapeake Bay. The different trends are analyzed concurrently with the main events and management strategies which occurred. Three main periods are identified : (1) the great fishery when annual oyster landings from 1840 to 1890 reached 600,000 metric tons. This period was characterized by gross overfishing and the destruction of oyster habitat by the oyster gears; (2) the reduced but stable landings from 1900 to 1980, with failure of the reseeding plan connected to heavy sedimentation and anoxie summer conditions. Landings did not exceed 80,000 metric tons; (3) the large decrease of production (1981-1988), with landings as low as 15,000 metric tons...

Structure et organisation de l'étang de Thau d'après la faune benthique (macrofaune, méiofaune). Relations avec le confinement
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Guelorget, O; Perthuisot, Jp; Lamy, N; Lefebvre, A.
The biogeological organization of Thau lagoon was investigated through the granulometric analysis of surficial sediments and study of the qualitative and the quantitative distribution of benthic macrofauna and meiofauna. These show clearly that the lagoonal system is organized according to confinement as conceived by Guelorget and Perthuisot (1983 a; 1992), which depends upon the rate of exchanges with the open sea and the hydrodynamic pattern of the basin. The latter appears to be composed of a pair of lagoonal subsystems separated by a hydrodynamically unstable barrier. The northern subsystem displays the classical concentric organization of Mediterranean lagoons with a clearly defined hydraulic umbilicus. The southern subsystem displays a transverse...

An example of GIS potentiality for coastal zone management: preselection of submerged oyster culture areas near Marennes-Oleron (France)
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Durand, H.; Guillaumont, Brigitte; Loarer, Ronan; Loubersac, Lionel; Heral, Maurice; Prou, Jean.
The Charente Maritime coast, in central western France, is the most important area for oyster and mussel production in Europe. High density, in this restricted intertidal area, induces low growing rate and socio-economic difficulties. One of the possible solutions is to shift some oysters from intertidal area to submerged areas. Bathymetry, sedimentology, hydrodynamism, fisheries and administrative rules are some conditions which are considered to establish the better selection of potential zone. The successive steps of setting up the prototype of GIS are presented: digitized traditional data from charts, extracted data from grid models (hydrodynmaic model), merging of thematic covers, proposal of favorable areas. The results are discussed especially on...

Downward flux of particulate dimethylsulphoniopropionate (dmspp) in the tropical open-ocean
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Corn, M; Belviso, S; Nival, P; Vigot, A; Buatmenard, P.
We report results from free-drifting sediment trap deployments at 200 m depth which enable measurement of the diel variations in the downward flux of detrital particulate dimethylsulphoniopropionate (DMSPp) over periods of 24-72 hours in three contrasting trophic regimes of the tropical northeastern Atlantic Ocean off Mauritania. The source of DMSPp was the phytoplankton living in surficial water layers. The three regimes exhibited similar strong diel cycles, the nocturnal fluxes being up to 100-fold lower than the daytime fluxes. High (or low) detrital DMSPp, fluxes were associated with high (or low) numbers of pteropods trapped inside the sampling cups. Thus, contamination of sinking material is likely to have occurred, promoting an overestimate of the...

Autores: Crassous, Philippe; Khripounoff, Alexis.
Nine sediment traps were assembled in triplicate on a frame and deployed at 100 m above the bottom in the California abyssal plain (4 100 m depth) for ten days. The distances between traps were from 30 cm to 11 km. The main flux measured during this period was 167 mg m(-2) day(-1) with a minimum of 43 mg m(-2) d(-1) and a maximum of 283 mg m(-2) d(-1). This high variation of the particulate flux at the kilometric scale was also observed at a metric scale: for example, the particulate flux measured with one of triplicate traps was equal to 82.3 +/- 46.5 mg m(-2) d(-1) (more than 50 % of variation) between traps distant of less than 1 m. To explain this heterogeneity of the flux measurement, some hypotheses are developed in this study: sampling artefact,...

The study of logbooks from commercial fishermen on the Adour River and commercial samples allowed characterization of the allis shad population (Alosa alosa L.) caught during the period 1988-91. A better knowledge of the influence of hydroclimatic factors (rate of river flow and intensity of tidal coefficient) on the catchability of the species in that never was also obtained. Allis shad are mainly recruited to this fishery from the beginning of April to the end of May: between 78 and 89 % depending on year. Males in the population were on average younger than females. However, at the same age, males were significantly smaller in size and in weight than females. These results reinforce the knowledge already obtained on French stocks in the Loire and...

Autores: Hoepffner, N; Barker, T; Nykjaer, L; Estrada, M; Schlittenhardt, P.
Spectral models of solar irradiance in the atmosphere and underwater are combined with satellite ocean colour data to determine the water column integrated daily rate of primary production in an upwelling centre off the coast of Mauritania. The local algorithm of primary production is based on first principles of photosynthetic physiology in marine algae, and accounts for some optical characteristics of the atmosphere over various marine environments. The results (integrated daily rate of primary production) are shown for different computational schemes, including the segmentation of the studied area into several provinces, each of them having a proper set of bio-optical and meteorological parameters. Some examples are given to illustrate the validation of...

Microbial utilization of occurring hydrocarbons by the sediment microbiota of Guaymas basin hydrothermal site (Gulf of California) The Guaymas Basin (Gulf of California) is an actively spreading oceanic basin and a site of hydrothermal activity. The basin floor, at about 2,000 m depth, is covered with a thick layer of pelagic sediments. The thermal alteration of recent sedimentary organic matter by the hydrothermal system generates hydrothermal petroleum.

Un capteur biologique original enregistrant les mouvements valvaires des mollusques bivalves
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Floch, Armelle.
L'auteur définit le concept de capteur biologique détectant les altérations de l'environnement à partir des réponses d'espèces sentinelles, puis présente les principaux systèmes existant en milieu aquatique. Il réalise ensuite la validation de deux dispositifs nouveaux enregistrant les mouvements valvaires de mollusques bivalves. Après une étude des principes de mesure, il analyse le comportement valvaire de moules marines, en conditions normales et lors de variations de la qualité de l'eau. Une discussion méthodologique sur ces capteurs valvaires conclut cette partie expérimentale, suivie d'une revue des applications envisageables, principalement en surveillance de l'environnement aquatique, dulçaquicole et marin.

Recherche de micro-organismes toxinogènes associés aux dinoflagellés responsables d'intoxication diarrhéique sur les côtes françaises
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Sechet, Veronique.
Ce document fait l'état des connaissances sur l'influence des bactéries au niveau de la dynamique des efflorescences marines à caractère toxique. Il prend également en compte les donnés récentes sur la production bactérienne autonome des "phycotoxines" et sur l'application de nouvelles technologies, immunologiques et génétiques. L'handicap majeur en toxicologie bactérienne est le manque d'information sur la composition spécifique des assemblages procaryotiques naturels dans les milieux aquatiques. Seul un infime pourcentage (moins de 1 %) des bactéries du milieu marin peut être isolé sur milieux gélosés. Des technologies nouvelles sont donc nécessaires pour 1°) mettre en évidence une éventuelle production bactérienne autonome des toxines, durant les...

Simulation of o-2, po4 and organic-carbon behavior during a benthic chamber experiment on the deep-sea floor
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Rabouille, Christophe; Gaillard, Juliette.
Using a time-dependent model for organic matter mineralization by oxygen and the resulting phosphate production in deep-sea sediments, the progress of a benthic chamber experiment is simulated. Assuming a known steady state as starting condition, the vertical distribution of chemical species in the sediments, pore water and solids, and the concentrations in the benthic chamber are calculated. Compared to previous approaches, the computation scheme utilized here considers explicitly a coupled and non-linear kinetic formulation of organic carbon oxidation and oxygen reduction. The purpose of this modeling approach is to assess the validity of conventional interpretations of benthic chamber experimental data. The results of the calculations show that the...

Seamount,anton,dohrn and the evolution of the rockall trough
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Jones, Ejw; Siddall, R; Thirlwall, Mf; Chroston, Pn; Lloyd, Aj.
Seismic data from the flat-topped Anton Dohrn Seamount in the central Rockall Trough reveal that the feature is capped by a thin (approximately 100 m) sedimentary layer which covers an extensive erosion surface lying approximately 800 m below sea level. The surface of erosion truncates a volcanic sequence that outcrops on the eastern side of the seamount to form a well-defined terrace from which alkali basalts and chalks of late Cretaceous age have been recovered. A refraction profile shot over the summit plateau and ultrasonic measurements on the basalts suggest that sedimentary and volcanoclastic units are abundant constituents of a low-velocity (3.69 km s-1) volcanic core which persists to depths of over 1 500 m. The seamount differs from the shallow...

Water-level variations in the northern levantine sea
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Yuce, H; Alpar, B.
Characteristics of water level variations in the northern Levantine Sea have been investigated by reference to a sequence of hourly water level observations at Antalya and Iskenderun. Long and short period oscillations of non-tidal origin have been identified. Long-period oscillations (several days) correspond to variations in barometric pressure; the short-period oscillations (2.8 to 4.6 hours) can be attributed to seiche-like motions. The tidal oscillations are small in amplitude, with a spring range of 21 and 41 cm in Antalya and Iskenderun respectively. Tidal oscillations are dominated by semi-diurnal constituents. The seasonal fluctuations of monthly mean sea level show two maxima and two minima; the major minimum occurs in March and is followed by a...

Autores: Colin, C; Bourles, Bernard.
Pegasus current measurements carried out along a section located off French Guiana are presented; the section was repeated five times from September 1989 to June 1991 during the NOE (region Nord-Ouest equatoriale)/STACS (Sub Tropical Atlantic Climate Studies) cruises on board the NOAA (National Oceanographic and Atmospheric Administration) research vessels. The data (vertical and horizontal distributions) show, as suggested by earliest observations, the presence of different currents. At the surface, and in winter, the North Brazil Current (NBC) flows northwestward (positive), is strong (120 cm/s), confined in the first 250 m, coastally trapped (within 250 km) and fed by offshore waters; in summer the NBC strengthens (the velocity increases to 150 cm/s),...

Apports des hautes résolutions spatiales pour l'étude et la cartographie des algues vertes.  Application à la grève de St-Michel(22)
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Ruiz, Olivier.
The increasing amounts of agricultural effluents associated with particular hydrodynamical locations are resulting in strong proliferations of suspended green algae Ulva lactuca. During ebb tide, the algae deposit on beaches, creating a nuisance for both tourism and fishermen. Biomass estimates are hence needed both for understanding the phenomenon and for measuring its magnitude. During the spring tide period of September 1993, two high resolutions digital sensors were run jointly on the French A.R.A.T (Remote Sensing and Atmospheric Research Aircraft). A pushbroom instrument called RAMI (run by C.N.E.S.) with spectral bands identical to those of S.P.O.T. and the Canadian C.A.S.I (which possesses a lot of spectral bands) acquired images over the sandy...

On the radiational anomaly in the global ocean tide with reference to satellite altimetry
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Cartwright, De; Ray, Rd.
The increasing precision of satellite altimetry in relation to tides justifies making a distinction between the gravitationally generated S-2 tide and its observed values in the ocean, which are affected indirectly by solar radiation. In view of the relatively high noise background, we propose a simplified form of response analysis in which the purely solar semidiurnal harmonics of the gravitational potential are modified by an arbitrary amplitude-factor R* and a phase lag r*. Analysis of a globally representative set of 80 tide-recording stations shows that the observed S-2 constituent is strongly coherent with its gravitational part deduced from lunar tides, with regression constants R* = 0.97, r* = 5.9 degrees. The corresponding 'radiational anomaly has...

Autores: Muller, Fll; Tappin, Ad; Statham, Pj; Burton, Jd; Hydes, Dj.
Two transects across the Celtic Sea and adjacent continental slope in August 1985 and August 1988 illustrate the importance of dynamic physical processes on dissolved trace metal distributions (Cd, Ni, Cu, Pb, Co, Fe, Mn). The influence of a coastal frontal zone can be seen in the 1985 transect, while an intrusion of open ocean waters into the shelf environment is the main factor influencing the horizontal distribution of trace metals in 1988. A third transect across the continental slope bordering the Porcupine Seabight (May 1984) reveals marked horizontal fronts in the concentrations of Fe, Mn and Cu at the shelf edge (over a 21 km distance, concentrations fall from 3 to 1 nM for Fe, from 2 to 0.5 nM for Mn, from 2 to 1 nM for Cu) which are unaccompanied...

Autores: Moguedet, Philippe.
During the years 1975, 1976, 1980 and 1982 cod (Gadus morhua) tagging experiments were conducted, inside the Gulf of St. Lawrence and outside in areas south of Newfoundland, by French scientists from IFREMER St. Pierre and Miquelon laboratory, in order to study the population distribution and migration and to complement the experiments carried out by Canadian scientists. The analysis from all recoveries and results from these experiments are presented here. The relevance is that the comparison with the Canadian results would lead to a better understanding of the cod stock exchanges in the area. The migratory patterns were believed to be mainly a response to seasonal environmental condition changes. In winter the cod were noted to migrate from the central...

During the French-Mexican cruise 'Guaynaut', carried out in November 1991 in the southern depression of the Guaymas Basin (gulf of California), an actively spreading oceanic basin, various samples were collected by means of the submersible 'Nautile'. The on-line coupling of purge and trap to capillary gas chromatography-mass spectrometry (P/T-GC-MS) has been applied to the analysis of volatile organic compounds (VOC) in water, sediments and hydrothermal deposit samples in order to contribute to the characterization of the bacterial microflora activity which is developed on this particular hydrothermal site. The results obtained for alkanes, monoaromatic hydrocarbons and organosulfur compounds lead to successful interpretation in terms of bacterial activity.

Depth profiles of amino-acids in porewater of sediments from the norwegian - greenland sea
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Mintrop, L; Duinker, Jc.
Dissolved free amino acids (DFAA) and dissolved combined amino acids (DCAA) were determined in the porewater of sediment cores from the Norwegian-Greenland Sea (water depth from 1000 to 3300 m). Concentrations in the sediment column were generally found to decrease with depth. The amino acid composition of DFAA and DCAA was remarkably constant. The relative contributions of acidic amino acids decrease with depth, however. Composition patterns for samples for water depth 1000-2000 m and for deep-sea samples (water depth &gt; 3000 m) show characteristic differences. Some secondary concentration maxima several centimeters below the sediment-water interface are found, probably related to the bioturbation activity of benthic macrofauna.

Experimental transmission of a Herpes-like virus to axenic larvae of Pacific oyster, Crassostrea gigas
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Le Deuff, Rose-marie; Nicolas, Jean-louis; Renault, Tristan; Cochennec, Nathalie.
A herpes-like virus which was associated with mortalities amongst hatchery-reared larvae of Pacific oysters, Crassostrea gigas. was observed for the first time in France during the summer 1991 (Nicolas et al.. 1992). Since this first report, we have noted further outbreaks of the disease in the summers of 1992 and 1993 in hatcheries on the western coasts of France in which a similar virus was associated with moribund larvae. Moreover, in the summer 1991, Hine et al. (1992) described a herpes-like virus responsible for larval mortality of hatchery reared C. gigas, in New Zealand. Ail these viruses are c10sely related with respect to their size and morphology and to their apparent cellular tropism for fibroblastic cells.

La modélisation de la dynamique sédimentaire est conduite en conformité avec les objectifs susmentionnés. L'étude est scindée en deux parties. En considérant une maille égale à 500 m (au lieu de 1000 m) et la même implantation géographique du maillage, le premier chapitre a pour objectif de valider le calcul hydrodynamique et de diagnostiquer le calcul hydro-sédimentaire dans sa ' nouvelle configuration. Sur la base des résultats précédemment acquis, des choix sont réalisés et appliqués au niveau de la calibration du modèle (chapitre 2). Pour des raisons indépendantes de notre volonté et de nos compétences, le chapitre de l'agitation (houle, clapot) n'a pu être abordé dans le cadre de cette étude.

Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Ollitrault, Michel.
From July 1983 to June 1989, the TOPOGULF experiment took place in the North Atlantic, to investigate the large scale and mesoscale circulations in the area of the Mid-Atlantic Ridge (MAR). The TOPOGULF experiment comprised hydrographic (CTD, O2 and nutrient data) sections, long-term current meter measurements, tracking of lagrangian surlace and subsurface floats, and geochernical observations. Hydrographie and eulerian data have aIready been published (The TOPOGULF group, 1986 and 1987). This data report presents the results obtained from the 3 surface drifters and the 30 SOFAR floats launched during the TOPOGULF experiment. In early July 1983, 3 surface drifters, drogued at 100 m depth and 15 SOFAR floats ballasted for 700 dbar were launched in the...

Spécificités des mollusques, conditions de mise en oeuvre chez l'huître creuse Crassostrea gigas à l'échelle de l'écloserie et premiers résultats de terrain
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Gerard, Andre.
The reproduction effort in Crassostrea gigas, as in most bivalve molluscs, has priority over their somatic growth. At the beginning of spring, the energetic metabolic processes are geared towards gametogenesis over glucidic stocks, thus inducing a slowing down of the growth and a change in the organoleptic qualities of the flesh (Héral &amp; Deslous-Paoli, 1983). The same authors showed that this effort increases along with age (figure 1). In young one-year-old oysters, the energy is mostly burnt in growth, only 18 % is involved in reproduction, whereas in two-year-old oysters, 60 to 65 % of the energy is used for gamete formation (Deslous-Paoli &amp; Héral, 1983). In order to limit the impact of gonadogenesis and to try and re-orientate this energy flux...

Bilan des essais d'élevage du pétoncle noir, Chlamys vria (Linné) dans le Bassin d'Arcachon France

Autores: Robert, Rene; Trut, Gilles; Laborde, Jean-louis; Miner, Philippe.
Until 1960, the black scallop Chlamys varia (Linné, 1758) was largely distributed over the French Atlantic coast. Nowadays, most of the deposits are gone. Since controlled mollusc reproduction techniques are now relatively mastered, some reimplatation attempts have been conducted on a number of oyster culture sites, including the Arcachon Bay, from 1989 to 1992. Despite some good results in hatchery and nursery, the rearing attempts failed. If some good growth rates have been monitored in the Arcachon Bay over these three years, these performances have been frustrated by very high mortality rates occurring shortly after the setting up of the farms. Although this species is known to be relatively sensitive to environmental factors, the hydrobiological...

Project analysis and market analysis, two complementary tools to help aquaculture fit demand : the cases of scallop and sea-bass
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Paquotte, Philippe.
Despite its youth, aquaculture is faced with market difficulties which make profitability of the activity more and more difficult to reach. Time is long gone when the price ofsome top-grade sea products was very high and the demand seemed limitless. In a context of uncertainty concerning economic conditions, institutional rules and characteristics of the demand, it is very important to have tools to facilitate decision-making by investors, bankers, entrepreneurs, researchers and public-policy makers. The first tool we propose is the market analysis. This is necessary to check adequacy between supply and demand. It is aimed at describing the present state of the market for a range of products (origin, characteristics, seasonality, volume and price) in order...

La collecte d'informations dans le cadre du réseau de suivi du phytoplancton (REPHY) au laboratoire de La Tremblade a pour but de suivre les fluctuations phytoplanctoniques et de mettre en évidence leurs effets sur le cheptel et sur la santé publique. La mise en place d'un second point de surveillance à Boyardville a permis de mieux cerner la pénétration des efflorescences phytoplanctoniques dans le bassin de Marennes-Oléron, et ainsi d'avoir une meilleure connaissance des phénomènes sur l'ensemble du secteur. On peut retenir que globalement la charge phytoplanctonique a été moins élevée en 1989 par rapport à 1988 avec une abondance plus grande en Dinoflagellés. Les Dinophysis spp ont été présents à faible concentration (maximum de 400 cell.l-1 en octobre)...

Geochemical features of site-840 from the tonga platform - a comparison with the other sites from leg-135 odp
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Vitali, F; Blanc, G; Larque, P; Samuel, J.
The sedimentary sequence recovered at Site 840 ODP in the Tonga Platform is 597 m thick and ranges in age from Holocene to late Miocene. Here, from the 49 samples analysed, three classes of sediments can be identified, based on their proportion of biogenic carbonate and volcanogenic content. These three classes are comparable with those previously differentiated in the Lau Basin (Sites 834-839) and with some sediments from the Tonga Trench Margin (Site 841). In constrast with neighbouring Site 834-839 sediments from the Lau Basin, the Site 840 sediment composition appears to be exempt of hydrothermal pending material and seems to be characterized only by biogenic and terrigenous andesiticrhyolitic volcanic inputs. The alteration of volcanic material...

Numerical-simulation of the turbidity maximum transport in the gironde estuary (france)
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Li, Zh; Nguyen, Kd; Bruncottan, Jc; Martin, Jm.
A coupled two-dimensional vertical width-integrated hydrodynamic and sediment transport numerical model is presented to simulate the ''turbidity maximum'' formation and dynamics in the Gironde estuary. A turbulence closure sub-model is used to parametrize the turbulent mixing process. The numerical results of a five-day simulation are compared with field measurements carried out at several locations. The formation and the displacement of the turbidity maximum during one tidal cycle are correctly simulated. The intensity of the ''turbidity maximum'' is strongly related to the turbulent energy field. The influence of the tidal amplitude on the suspended matter transport is also studied during the simulation.

Autores: Dardignac, Marie-jose.
Les stocks de moules en élevage dans les bouchots du Pertuis Breton ont été estimés chaque année de 1988 à 1993. Après un bref rappel de la méthode utilisée, le problème dû à l'évolution de la biomasse pendant la période d'échantillonnage est évoqué. Les résultats montrent que le volume de moules commence à diminuer en 1990, passe par un minimum en 1991 puis remonte très légèrement en 1992. Aucune augmentation n'est observée en 1993. Les facteurs susceptibles d'être responsables de cette évolution sont étudiés.

L'IFREMER a fêté ses dix ans en 1994. Au cours de la décennie écoulée, la recherche océanographique a connu de profondes mutations dans la définition et la prise en compte de nouveaux problèmes nécessitant la mise en place de programmes à grande échelle et de nouveaux moyens : raréfaction des ressources halieutiques, climat, environnement littoral ... Ainsi le rôle capital de l'océan mondial a conduit à développer de grands programmes rendus possibles par l'amélioration notable des moyens de mesure et d'observation, en mer ou embarqués sur des satellites, et par le spectaculaire développement des moyens de calcul. Le milieu littoral, par son importance dans le fonctionnement de l'océan, le devenir et la valorisation des ressources halieutiques, par leur...

La transformation stable de cellules SF9 de Lépidoptère a été mise au point et l'efficacité de différents vecteurs d'expression a été comparée. Cela nous a permis de mettre en évidence un activateur transcriptionnel sur le génome du densovirusJcDNV. Nous avons fait exprimer des ARN anti-sens artificiels dirigés contre des gènes d 'AcMNPV dans les cellules SF9. Nous avons mis en évidence des ARN transcrits en sens inverse sur le promoteur du gène de l'ADN polymérase (dnapol) du baculovirus AcMNPV, mais il a été établi qu'ils n'avaient aucun effet sur la transcription du gène dnapol. Alors, nous avons déterminé que ces ARN avaient la capacité d'être traduits en une protéine dont la fonction reste inconnue.

Autores: Druet, C; Zielinski, A.
The paper presents a one-dimensional mathematical model describing the vertical distribution of chlorophyll a and nutrients in a stratified sea. The model takes into account the most important physical, chemical and biological processes controlling the evolution of this function. This model was tested with data obtained in situ during the Baltic research expedition of R/V Prof. Siedlecki in 1980. The vertical distributions of temperature field, chlorophyll a and nutrient concentrations were taken as initial conditions for various simulations. The results of numerical simulations explained the influence of biological processes on the variability of phytoplankton concentration in time and space under various dynamic conditions.

Sélection des mollusques : bilan et nouvelles perspectives concernant la croissance, la qualité et les résistances aux maladies
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Naciri, Yamama.
In the case of molluscs, the implementation of selection programs with a precise evaluation of the available genetic variability and the estimate of the transmissibility of the characters as well as their correlations, face two main obstacles: the first one, specific, derives from the existence of some reproduction systems that are sometimes complex and still imperfectly mastered as for the flat oyster plate Ostrea edulis; the other, more general, is directly dictated by the importance of the infrastructures needed to keep a large number of differentiated families in controlled farming conditions. Despite these obstacles, a number of programs have been developed over the last twenty years with encouraging results.

The uptake and release of material by oysters (Crassostrea gigas) in the intertidal zone were estimated in situ in the Bay of Marennes-Oléron (France) in spring and autumn. 10 m long plexiglass tunnels were placed over small tables with bags containing oysters or empty oyster shells (control). Although in the very turbid conditions of the water column sedimentation of suspended particulate material could be observed in control experiments, higher fluxes (uptake) of seston, POC and PON and especially chlorophyll occurred in the presence of live animals. Release of dissolved nutrients was not evident from the tunnel with oysters, which is in contrast with studies in other areas with bivalves. This is ascribed to limited mineralization of biodeposits as an...

Afin d'améliorer les gestion des bassins conchylicoles, de nombreux auteurs ont élaboré des modèles mathématiques simulant les activités physiques et biologiques des bassins étudiés (Bacher et al.. 1990, bassin de Marennes-Oléron ; Bioteau, 1993, étang de Thau ; Chapelle, 1993, Baie de la Vilaine ; Radford. 1993, mer du Nord ; Smaal et Scholten, 1989, bassins mytilicoles hollandais; Santhanam et al., 1990, sud-est de l'Inde ; Keizer et al., 1987, bassin de Cumberland). Un des problèmes majeurs qui se pose au modélisateur est l'estimation de la capacité trophique d'un bassin. Quel facteur est le plus représentatif de la nourriture disponible pour les mollusques filtreurs ? Widdows et al. (1979) caractérisent le potentiel nutritif disponible pour les...

Seston dynamics and bivalve feeding in the Bay of Marennes-Oléron (France)
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Zurburg, Wouter; Smaal, Aad; Heral, Maurice; Dankers, Norbert.
Within the framework of an investigation into the carrying capacity of the Bay of Marennes-Oléron (France) for bivalve culture, the in situ uptake of suspended particulate material by oysters (Crassostrea gigas) and mussels (Mytilus edulis) was determined in experiments with benthic ecosystem tunnels. Very high fluctuations in seston quantity and quality were observed within and between tidal cycles. The percentage of organic carbon was inversely related to seston quantity at low concentrations. Organic carbon was diluted by resuspension of material rich in inorganic matter. At high seston concentrations a constant level of about 2% organic carbon was found. The CIN ratio was relatively constant throughout the seasons and fairly low (6.5 to 8.4). Owing to...

Autores: Le Traon, Pierre-yves; Stum, J; Dorandeu, J; Gaspar, P; Vincent, P.
A global statistical analysis of the first 10 months of TOPEX/POSEIDON merged geophysical data records is presented. The global crossover analysis using the Cartwright and Ray (1990) (CR) tide model and Gaspar et al. (this issue) electromagnetic bias parameterization yields a sea level RMS crossover difference of 10.05 cm, 10.15 cm, and 10.15 cm for TOPEX-TOPEX, POSEIDON-POSEIDON, and TOPEX-POSEIDON crossovers, respectively, All geophysical corrections give reductions in the crossover differences, the most significant being with respect to ocean tides, solid earth tide, and inverse barometer effect. Based on TOPEX-POSEIDON crossovers and repeat-track differences, we estimate the relative bias between TOPEX and POSEIDON at about -15.5 +/- 1 cm. This value...

Autores: Mialhe, Eric.
Les productions d'invertébrés sont prépondérantes en aquaculture marine qui est économiquement très importate pour un grand nombre de pays, notamment de la zone Sud. Cette activité est confrontée à de nombreux problèmes des pathologie qui remettent en cause sa périnnité et son développment. Jusque dans les années quatre-vingt, les travaux relatifs à la pathologie des mollusques et des crevettes ont essentiellement porté sur la description des agents pathogènes. La création en 1985 par l'ISTPM/IFREMER d'un laboratoire pourvu de tous les équipements nécessaires aux techniques de pathologie a permis de mettre en place un programme de recherches orienté vers le contrôle des maladies. Une double stratégie de travail a été alors défine pour apporter  à...

In the present paper three new species of the genus Adelophryne from the coastal Atlantic forest in Brazil are described. The species are separated from the two species formerly known from the Amazon forest by caatinga vegetation and a distance of at least 1600 km. A. pachydactylus from Bahia has a reduced number of phalanges in the fourth finger, and large subdigital pads under fingers and toes. A. baturitensis has distinct subarticular tubercles under the toes and a relatively large size. A. maranguapensis has large discs on fingers and toes and is boldly patterned. During fieldwork in Amapá two specimens of A. gutturosa were collected and based on them additional data are provided and some concepts from the original description are revised. Literature...

On altitude dependent characters in Albinaria idaea (L. Pfeiffer, 1849), with a revision of the species (Gastropoda Pulmonata: Clausiliidae)
Provedor de dados: Naturalis Digital Academic Repository
Autores: Engelhard, G.H.; Slik, J.W.F.
Several forms of Albinaria idaea (L. Pfeiffer, 1849) have been described as (sub)species from various sites on Mt. Ida (Central Crete). In recent years, however, much additional material has been collected, which made clear that no sharp boundaries exist between these forms. Moreover, several characters proved to be altitude dependent to a certain extent. It may be concluded that on Mt. Ida only a single evolutionary entity can be distinguished, viz. A. i. idaea. On the isolated Mt. Kedros, south-west of Mt. Ida, an undescribed allopatric form was found, which because of its smaller size and differences in altitude dependent characters was given subspecific rank as A. i. amabilis ssp. nov. On the Paximadia Isles, south of Central Crete, a percostate and a...

Two new Mycenas of section fragilipedes from southern Norway
Provedor de dados: Naturalis Digital Academic Repository
Autores: Aronsen, A.
Mycena austera and Mycena parca, belonging to section Fragilipedes, are proposed as new species. Mycena austera is identified mainly by the 4-spored basidia, the absence of clamp connections, the dark pileus, and the nitrous odour. The species is compared with M. leptocephala and M. deceptor. Mycena parca is compared with M. leptocephala from which it differs mainly on account of the absence of nitrous odour, and differently shaped cheilocystidia and terminal cells of the cortical layer of the stipe.

Advertisement calls of Bolivian species of Scinax (Amphibia, Anura, Hylidae)
Provedor de dados: Naturalis Digital Academic Repository
Autores: Riva, Ignacio de la; Márquez, Rafael; Bosch, Jaime.
The advertisement calls of eight Bolivian species of Scinax are described including information on the calling behaviour of each species. A characteristic audiospectrogram and oscillogram are presented for each species, as well as numerical information about the spectral and temporal features of the calls. Two phenograms based on the characteristics of the mating calls are constructed, the first one using a traditional multivariate technique (UPGMA) and the second one using audiospectrogram correlation, a new technique that allows holistic comparisons of single vocalizations.

A new variety of Sarcotheca Laxa (Oxalidaceae) from Sumatra
Provedor de dados: Naturalis Digital Academic Repository
Autores: Veldkamp, J.F.
In 1985 during the Fourth Expedition to S Aceh, Sumatra, in the neighbourhood of the G. Leuser National Park a representative of Sarcotheca (Oxalidaceae) was collected. It clearly is a member of the S. laxa complex previously known only from Malaya and the Riouw Archipelago. It differs from all by the golden puberulous, soon glabrescent innovations, the thicker, broader, more ovate leaflets, and the structure of the inflorescences (short, slender, subequally branched). In the technical characters it seems closest to var. sericea (Ridley) Veldk., but it differs by the leafblades with fewer pairs of nerves, the sparsely white puberulous inflorescence axes and branches (the hairs can easily be distinguished separately and seem longer), the pedicels with the...

Taxonomy, phylogeny, and geography of Neoscortechinia Hook. f. ex Pax (Euphorbiaceae)
Provedor de dados: Naturalis Digital Academic Repository

Six species are recognized in Neoscortechinia, two more than before, because N. angustifolia is raised to species level and N. forbesii is split into N. philippinensis (new combination) and N. forbesii s.s. The varieties of N. kingii are united. The genus Cheilosa, which closely resembles Neoscortechinia, is kept separate and it is used as the outgroup in the cladistic analysis of Neoscortechinia. The latter analysis resulted into a cladogram, which shows a first branching off of the sister species N. angustifolia and N. sumatrensis, followed by a subsequent branching off of N. nicobarica, N. philippinensis, and finally N. forbesii and N. kingii. Four of the six species show a wide-spread distribution in W Malesia ( N. kingii, N. nicobarica, N....

On October 1st, 1993 Professor Dr. Hermann Otto Sleumer died at the age of 87, after a short illness. His ashes have been interred at Liederbach (near Kirchberg), Germany. Dr. Sleumer had been our colleague at the Rijksherbarium and eminent contributor to Flora Malesiana for many years. He generously shared his vast knowledge and experience with many of us. For younger botanists the many anecdotes and intimate stories he indulged in telling about colleagues he had known, especially from the Englerian circles in Berlin, were always an enriching and entertaining experience.

Tintinnomorphs from deep-sea sediments of the Banda Sea (Indonesia)
Provedor de dados: Naturalis Digital Academic Repository
Autores: Waveren, I.M. van.
Preservational circumstances, probably related to high productivity and high sedimentation rates, result in the occurrence of a wide variety of tintinnid palynomorphs in (sub-)Recent sediments of the Banda Sea. These organic (probably chitinous) remains include both loricae and cysts, as well as the stalked pouches in which the cysts were originally encapsulated. Collectively termed 'tintinnomorphs', these palynomorphs are described and classified in an informal scheme that may serve as a key to the recognition of 76 morphologically distinctive types.

Review
Provedor de dados: Naturalis Digital Academic Repository
Autores: Wilde, W.J.J.O. de.
In this volume the author concentrates on the comparative study of tropical flowers. He gives a practical approach (see Introduction, page 3) to recognize tropical flowers at three levels: a) Organization (‘Bauplan’), with emphasis on history and macroevolution (see Chapter 2); b) Construction (‘Gestalt’), i.e. architecture (see Chapter 3); and c) Mode, with emphasis on ecology and microevolution (see Chapters 4 &amp; 5). Its scope is the understanding or biological interpretation of characters and character variation of flowers for the phylogenetic reconstruction of the angiosperms at these levels. The author claims that knowledge of the phylogenetic history and of the interactions between animals and plants may be of vital importance for the evaluation...

Chitinous palynomorphs and palynodebris representing crustacean exoskeleton remains from sediments of the Banda Sea (Indonesia)
Provedor de dados: Naturalis Digital Academic Repository
Autores: Waveren, I.M. van.
Palynological residues from surface sediments in the Banda Sea (Indonesia) are characterised by the presence of chitinous palynomorph types that can be correlated with exoskeletons of crustaceans, notably calanoid copepods. A series of 27 palynomorph types are described and informally categorised. Also the quantitatively prominent transparent palynodebris and its diffuse degradation products are derived from crustaceans. Selective preservation of the chitinous remains is considered to be related to the effects of high plankton production and high sedimentation rate.

Nogmaals de Franse aardkastanje [Conopodium majus (Gouan) Loret]
Provedor de dados: Naturalis Digital Academic Repository
Autores: Slim, P.A.; Londo, G.
Naar aanleiding van de vondst in 1988 van Conopodium majus te Bentheim (D)¹ kunnen wij melden dat deze neofiet ter plaatse al zeker 12 jaar langer voorkomt. Op 3 juni 1976 maakte de afdeling Botanie van het vroegere Rijksinstituut voor Natuurbeheer een excursie naar onder andere het Bentheimerwald. In een gazon op vochtige, lemige bodem nabij het ‘Kurort’ werd in lichte schaduw van de bosrand een niet-bloeiende Umbellifeer gevonden, die in de harde kalkondergrond een knol bleek te hebben. Hij werd vergezeld door Phyteuma spicatum subsp. nigrum, Sanicula europaea, Carex pallescens, Poa trivialis, P. annua, Plantago major, Dactylis glomerata, Belis perennis, Taraxacum officinale, Glechoma hederacea, Aegopodium podagraria, Ajuga reptans, Anthoxanthum odoratum...

Nongeniculate Corallinaceae (Corallinales, Rhodophyta) from the spermonde Archipelago, SW Sulawesi, Indonesia
Provedor de dados: Naturalis Digital Academic Repository
Autores: Verheij, Eric.
A critical study of the nongeniculate Corallinaceae (Corallinales, Rhodophyta) from the Spermonde Archipelago, Southwest Sulawesi, Indonesia, has been carried out. More than 750 collections, including type- and other relevant collections, were examined. In total 16 taxa belonging to 7 genera of nongeniculate Corallinaceae are reported. These are Lithophyllum (4 species), Hydrolithon (3 species), Mastophora (2 species), Neogoniolithon (1 species), Spongites (2 species), Lithothamnion (1 species), and Mesophyllum (3 species). The synonymy, type collection(s), type locality (ies), specimens examined, a detailed description, and remarks are given for each taxon. Two collections are referred to an unidentified taxon, probably belonging to the genus Spongites.

Microcanuella bisetosa gen. n., sp. n., a new taxon of Canuellidae (Crustacea, Copepoda) from the Costa Rican Pacific coast, with remarks on Galapacanuella beckeri
Provedor de dados: Naturalis Digital Academic Repository
Autores: Mielke, Wolfgang.
A new canuellid, Microcanuella bisetosa gen. n., sp. n., was collected on the Pacific coast (Gulf of Nicoya) of Costa Rica. Though the male is still unknown, a new genus is established, mainly because of the reduced armature of P1, P4, and P5. The small-sized M. bisetosa sp. n. is a mesopsammic species, inhabiting the interstices of coarse sediments of a beach slope.

Het doel van deze presentatie is een overzicht te geven van wat er in de genoemde drie jaren aan gegevens is verzameld. Er wordt bekeken op welke wijze er wordt geïnventariseerd, hoe het staat met de landsdekking van de waarnemingen, of er grote verschillen in wijze van inventariseren zijn tussen de verschillende districten en of er in die drie jaren veranderingen in de wijze van inventariseren waarneembaar zijn. Tenslotte wordt aan de hand van enkele voorbeelden bekeken hoe zich wat FLORON in drie jaar gedaan heeft verhoudt tot de verspreidingskaarten in de Atlas van de Nederlandse Flora.¹ Het gevaar van het presenteren van grafieken in dit verband is al gauw dat er een soort competitie gaat ontstaan tussen de verschillende districten.

The genus Pseudocricetodon (Cricetidae, Mammalia) in the upper Oligocene of the province of Teruel (Spain)
Provedor de dados: Naturalis Digital Academic Repository
Autores: Freudenthal, M.; Hugueney, M.; Moissenet, E.
Two new species of Pseudocricetodon are described: P. simplex sp. nov. is characterised by a simple dental pattern in the lower molars. It has been discovered almost simultaneously in Oligocene beds near Martín del Río (Teruel Basin) and near Alcorisa on the southern border of the Ebro Basin. P. adroveri sp. nov. had previously been described from Vivel del Río as P. aff. thaleri, and is characterised by a complex dental pattern. These two new species change the current ideas on the evolution of the genus Pseudocricetodon.

Ook in 1995 zullen er weer een aantal meerdaagse excursies gehouden worden. Het zullen er dit keer meer zijn dan in voorgaande jaren. Hiervoor zijn verschillende belangrijke redenen. Tijdens de excursies worden km-hokken door groepjes floristen geïnventariseerd op het voorkomen van plantesoorten. Voor beginnende floristen zijn deze bijeenkomsten daarom zeer geschikt om determinatie-vaardigheden en soortenkennis op te doen. Daarnaast bieden ze de mogelijkheid om met andere floristen in contact te komen. Het uitwisselen van ervaringen en informatie blijft echter ook voor meer ervaren floristen belangrijk. De excursies leveren vaak aanzienlijke aanvullingen op reeds bekende gegevens. Een groep heeft tenslotte meer ogen en specialistische kennis in huis dan...

Agrarisch natuurbeheer: nieuwe perspectieven
Provedor de dados: Naturalis Digital Academic Repository
Autores: NN.
It is argued that the ongoing transformation of Dutch agriculture towards sustainability implies a renewed interest in those farming practices that till recently were considered to be ‘out-dated’ and/or ‘traditional’. Dutch agriculture contains a wide array of farming practices that differ from the dominant model. These deviant styles of farming turn out to be quite interesting from the scope of landscape maintenance and nature preservation. Special attention is paid to common initiatives as e.g. the one of farmers of the Frisian village of Eastermar. Some links between these new perspectives and the work of naturalists are highlighted.

The ultrastructure of the apical apparatus and lateral ascus wall is compared in Leotia lubrica and five species currently placed in the Geoglossaceae. The lateral ascus wall consists of two layers, of which the inner one increases in thickness in the apical apparatus. Considerable differences in substructure of both layers are described. On the basis of general morphology of the apical apparatus, structure and PA-TCH-SP reactivity of the apical thickening and annulus, and occurrence of an annular protrusion four main categories are distinguished. A reactive annulus is demonstrated in the apical apparatus of all species, including L. lubrica. The species studied are arranged as follows: Category 1a. Geoglossum nigritum and G. cookeianum; 1b.

Gymnocarpium dryopteris is rather rare in the Netherlands. Distribution and ecology have been surveyed, especially for the period 1979-1991. In this period the species was detected with more than 670 individual stands, 90% at the Kuinderbos. In this article the Kuinderbos population is compared with other Dutch populations. Gymnocarpium dryopteris prefers shadowy ditches, but may grow in various other habitats as well. Especially in the western and southern part of the Netherlands it is growing on walls. The vegetation on the sites belongs to different syntaxa, with a preference for the Quercion (Fago-Quercetum) or plantations (Pseudotsuga) and in the Kuinderbos especially plantations of Picea sitchensis.

The first edition of this work appeared in a single volume in 1969. Now, about a quarter of a century later, so many additional species had to be included, that two volumes are needed. Most of the additions are new species described since 1969, partly as a result of the splitting tendencies of some recent Australian botanists, of which Dockrill is highly critical. Each species is described in detail and illustrated with a full-page line drawing. While perhaps not of professional quality, the drawings are sufficiently clear and accurate to make the task of identifying almost any tropical Australian orchid a light one. In addition, all genera and species are keyed out. The distribution within Australia is usually given in considerable detail, but for those...

This book contains the proceedings of the special tapetum symposium, held during the VIII International Palynological Congress in 1992 (Aix-en-Provence, France). Twelve contributions demonstrate the importance of the tapetum in the reproduction of land plants. As the editors state: any tapetum malfunction causes pollen sterility. All papers deal with basic research, not with applied research such as plant breeding and genetic engineering. Although ‘evolution’ is listed in the title, very little (no special contribution) is devoted to this subject. It is a pity, because a phylogenetic theory has been suggested in the past, which should be treated in a book covering such a highly and diversely specialised structure.

Clerodendrum fistulosum (Verbenaceae), an unspecific Myrmecophyte from Borneo with spontaneously opening domatia
Provedor de dados: Naturalis Digital Academic Repository
Autores: Maschwitz, U.; Fiala, B.; Linsenmair, K.E.
Clerodendrum fistulosum Becc. is a true myrmecophyte as it offers nesting space for ants in hollow internodes. In contrast to previous reports our investigations proved that these domatia open by themselves, thus providing cavities for a variety of different ant species. In Sarawak, Malaysia, we did not find an obligate relationship between C. fistulosum and a specific ant-partner. For comparison, studies on herbarium material of other Clerodendrum species were carried out: a further species, C. deflexum from the Malay Peninsula and Sumatra presumably also is myrmecophytic.

Introduction Amid the gaudily-coloured parade of tropical crabs few are more splendidly patterned than the matutine genera. But the patterns decorating these species brought about taxonomic disarray and from the very beginning they baffled their researchers. Already in 1817 Leach remarked: "the characters which distinguish the species are very obscure". MacLeay (1838) wrote in exasperation: "there are many species confounded together under the name Matuta victor, I do not consider the above names of the family and genus to possess any authority". Stebbing (1905) concurred: "From the interminable discussion of minute differences, as to the importance of which distinguished authors neither agree one with another nor always with themselves, it seems safe to...

Most of these are now nature reserves. The various vegetation types are briefly described, and a few very rare species, such as Carex divisa and an annual form of Pedicularis palustris are mentioned. The environmental management of the nature reserves is outlined, and a planning for the near future is given.

Revisionary notes on Negulus O. Boettger, 1889, a genus of minute African land snails (Gastropoda Pulmonata: Vertiginidae)
Provedor de dados: Naturalis Digital Academic Repository
Autores: Bruggen, A.C. van.
The genus Negulus is reviewed; only four Recent species, restricted to continental Africa, are recognized. The genus is extinct in Europe, being only recorded from Tertiary deposits. A key to the shells of the Recent species (all figured) is supplied. The anatomy is as yet unknown. A sinistral shell of N. abyssinicus is described from among a series of paralectotypes in the Leiden Museum, the first such abnormality in the genus (figured). A fair amount of shell material has become available (among which some historical specimens) so that metric data may be compared with greater confidence. Recent occurrence is established/confirmed for Eritrea, Ethiopia, Sudan, Kenya, Tanzania, Zaire, Zambia, Malaŵi, and Bioko (Fernando Poo). The small size of the shell...

Review
Provedor de dados: Naturalis Digital Academic Repository
Autores: Roos, M.C.
This book summarizes in a rather popular way scattered information on the problem of conservation of plant diversity. Ordered to the eight major regions of the world, a rather arbitrary selection of about 2000 rare and endangered species are described, some 250 also illustrated, partly in colour. The commission on endangered plant species under the IUCN has estimated that c. 20,000 species of higher plants need protection, whereas they include only 250 species in the Red data book of plants. This illustrates the very much incomplete knowledge of the current conservation status of plant species. Therefore, any attempt to summarize the present state of knowledge is unavoidably rather erratic.

The northeastern Atlantic species Mycale micracanthoxea Buizer &amp; Van Soest, 1977 is a component of subtidal shallow water and brackishwater harbour poles and pontoons from The Netherlands, where it grows attached to shells, barnacles, etc. It was found in similar zones and habitats of Algeciras Bay (Gibraltar Strait, southern Spain) and Isla Cristina (Huelva, southern Spain) where it is very common. This new record constitutes the southernmost limit of the geographical range of this species. This article presents some data on the anatomical variability of Mycale micracanthoxea, along with a discussion on the possible causes of its observed distribution.

Owen revisited: a reappraisal of morphology in evolutionary biology
Provedor de dados: Naturalis Digital Academic Repository
Autores: Minelli, Alessandro; Schram, Frederick R.
A new analysis within the framework of developmental genetics provides both raw data and theoretical support to the “old” morphology and suggests a new, more predictive, approach to the concept of homology. We distinguish between “positional homologues” and “structural homologues” as independent components of the more general concept of homology. We discuss some general patterns seen in the anatomy of animals and in their morphogenesis. Slack et al. (1993) advanced the concepts of the “zootype”, a particular spatial pattern of gene expression, and the “phylotype”, a particular stage of embryonic development that expresses the zootype. We build upon these concepts and expand them. This allows us to propose some additional phylotypes (arthrotype, cyclotype,...

Secondary pollen presentation is a taxonomically widespread phenomenon that is unknown to many botanists. As defined by the author, it embraces those cases in which pollen is transferred within the flower, and presented to pollinators on or by floral structures other than the thecae. The intraflower transfer often involves intriguing adaptations of petals, androecium and distal parts of the gynoecium. The present book is largely a case of secondary presentation itself, being actually a review of the literature on the subject, supplemented with unpublished data and drawings. The main part (208 pp.) extensively describes familywise all taxa known to have secondary pollen presentation, with many comments inserted. Papaveraceae, Leguminosae, Proteaceae,...

A new account of the genus Myristica Gronov. in the Pacific area, here defined as comprising the Carolines, the Solomon Islands including Bougainville, and the islands further towards the East, up to Fiji and Samoa. There are 16 species and eight infraspecific taxa, most locally endemic. Three species, one subspecies, and two forms are described as new; five new subspecific combinations are proposed. Only one key to the species is given, to be used for male flowering as well as for female flowering or fruiting material. The key is primarily based on vegetative characters. Besides the typical appearance of the fruit, also the exact nature of the inflorescences ranks among the major characters for the distinction of species. Fruits are illustrated to enhance...

Between Arenaria leptoclados on the one side and A. serpyllifolia s.s. (including subsp. macrocarpa) on the other a difference exists in the structure of the mature, dry capsules. In A. leptoclados these usually have a dented or pleated appearance. When compressed between finger nails they flatten without breaking, or with some crumbling only. The dry capsules of A. serpyllifolia, however, are usually smooth. They are brittle and respond to pressure applied to the top part of the capsule by snapping open lengthwise. Usually they disintegrate entirely. Transverse sections of the mature capsule wall differ in absolute thickness (40-150 µm in A. serpyllifolia; 15-30 µm in A. leptoclados in sections taken through the middle portion of the fruit), as well as in...

Some relatively rare Taraxacum species of the sections Palustria and Celtica occurring in the province of Friesland are discussed. During the development of the plant five different stages can be distinguished, each with a different leaf morphology. This has led to the description of a number of superfluous species. The observation and comparison of cultivated plants may therefore lead to the synonymisation of a considerable number of names. Within the Taraxacum nordstedtii group of the section Celtica a number of different forms can be recognised when comparing cultivated plants and subjecting them to a genetic analysis.

In addition to a taxonomic review of the whole order Thermosbaenacea, the general morphology and chaetotaxy are discussed in detail. Due to the results of cuticular staining, and through the study of specimens with SEM techniques also, corrections to earlier interpretations could be made. A chaetotaxic classification, modified after the one of Watling (1989), is presented. In the taxonomic part 34 species are recognized, belonging to seven genera (one new), four families (one new). The examination of adult material of the type species of Monodella, i.e., Monodella stygicola Ruffo, 1949, warranted the creation of Tethysbaena gen. nov., to comprise all other taxa previously included in Monodella. Transferred to Tethysbaena are: M. argentarii Stella, 1951; M....

The present volume contains 73 families out of some 250-500 families which can be recognized within the Angiosperms, depending on the taxonomic concepts applied. The 73 families represent three major blocks of comparatively ‘primitive’ dicotyledons: Magnoliid, Hamamelid, and Centrospermous families. The families are treated in an alphabetical order, with among the larger families Aizoaceae (127 genera, with c. 2500 species), Annonaceae (128 genera, with c. 2300 species), Amaranthaceae, Cactaceae, Caryophyllaceae, Chenopodiaceae,...

This paper deals with silicified ostracods obtained from material dredged from Orphan Knoll, a submerged continental remnant in the Labrador Sea. Thirteen determinable species, belonging to the suborders Palaeoecopina and Podocopina, had been found in the material. Two species are new, the rest are left in open nomenclature. Among the smooth shelled podocopines, ancestral Pachydomellidae are of special interest, viz. Aboilia Becker &amp; Adamczak (type species A. blessi Becker &amp; Adamczak). The ostracod species are thought to indicate an age of Middle to Late Ordovician and include forms with both North American and North European affinities. It is believed that the collection of Ordovician ostracods is endemic at the species level and that they have...

A black, non-troglomorphic amphibian from the karst of Slovenia: Proteus anguinus parkelj n. ssp. (Urodela: Proteidae)
Provedor de dados: Naturalis Digital Academic Repository
Autores: Sket, B.; Arntzen, J.W.
A morphologically distinct cavernicolous salamander Proteus anguinus from southeastern Slovenia (Bela Krajina) is described as P. a. parkelj ssp. n. It differs from P. a. anguinus in a dark pigmentation, fully developed eyes, a skull with broader and shorter bones and fewer teeth, a voluminous jaw musculature that gives the head a bulky appearance, a proportionally longer trunk with a higher number of vertebrae, shorter extremities, and a shorter tail. Most of these traits are considered to be plesiomorphic character states. An allozyme analysis over 40 loci has shown the new dark pigmented taxon to be genetically similar to a white and troglomorphic neighbouring population from Stična (DNei = 0.23). Both populations in turn are genetically dissimilar to a...

A taxonomic and phylogenetic analysis of Rhysotoechia (Sapindaceae)
Provedor de dados: Naturalis Digital Academic Repository
Autores: Etman, B.
This study comprises a taxonomic revision of Rhysotoechia (Sapindaceae) preceded by a phylogenetic analysis. Fifteen species are recognised and three imperfectly known species are discussed. Five new species from New Guinea are described. Two species from the Philippines, Borneo and one species from Australia are reduced. There are no excluded species. A key, based on both flower and fruit characteristics, gives access to the species. The study was restricted to the macromorphological characters, leading to a data matrix with 25 characters. The cladistic analysis was run with the computerprogram HENNIG86. Eventually one cladogram has been accepted.

The subcommittee on Education and Training had an informal meeting in Yokohama. It asked the Board to contact the 6 major national institutions in the region (BO, BRUN, FRIM, LAE, SING, PNH) with the suggestion for each to appoint a person, who together should act as a regional clearing house (cf. recommendations of the Second Flora Malesiana Symposium). Prof. RIFAI and Dr. Roos will collect information to coordinate all research carried out by students in the region. Dr. BARLOW has proposed that he will organise a post-graduate training programme in Australia (from 1995 onwards) for Indonesian students (and – probably – for students from the other countries as well).

Taxonomic congruence between external morphology and male and female genitalia characters of members of Rasahus Amyot &amp; Serville (Heteroptera: Reduviidae: Peiratinae)

Autores: Coscarón, M.C.; Díaz, N.B.; Povel, G.D.E.
The occurrence and degree of taxonomie congruence is analyzed between classifications based on the external morphology and male and female genitalia of the genus Rasahus Amyot &amp; Serville, 1843 (Reduviidae) using multivariate analyses. The results demonstrate that a classification based on size differences, and a data set of ratios are incongruent with a classification of a set of characters of the male and the female genitalia. The last two classifications are congruent with each other at a speciesgroup level, e.g., that of the R. scutellaris and R. hamatus group. The classifications are discussed and a generalized phenetic classification is given.

Autores: Weeda, Eddy.
The occurrence of Poa bulbosa var. bulbosa (non-proliferous form) on the island of Ameland is discussed. It was first observed there in 1973. Eighteen years later it has settled in 26 kilometer squares. It occurs only along paths and roads in the dune area. On Ameland, the distribution pattern shows three main areas, separated by major gaps. All three areas are frequented by tourists. The bulbs may adhere to clothing of man and thus be spread. Usually only small intervals are bridged, but sometimes the species may travel considerable distances. This way, the plant may suddenly appear at distant localities.

A new species of Theridomys, T. truci, is described. It occurs in a stratigraphic succession at Saint Martin de Castillon (Vaucluse, France) approximately at the boundary between Lower and Upper Oligocene. Its characteristics are: small size; moderate hypsodonty; thin and regular enamel borders; flat occlusal surfaces; wide and short synclines and synclinids; first syncline of the upper molars of the same size as the second; the first synclinid begins its development in the lower molars and the fourth syncline in the upper molars; the external tubercles of the upper molars are fused, forming a labial wall. The phyletic relationships of T. truci are discussed and a new hypothesis on the evolution of the T. lembronicus lineage is proposed. Une nouvelle...

Are the genera Hallea and Mitragyna (Rubiaceae-Coptosapelteae) pollen morphologically distinct?
Provedor de dados: Naturalis Digital Academic Repository
Autores: Huysmans, S.; Robbrecht, E.; Smets, E.
Recent literature is controversial as regards the segregation of Hallea and Mitragyna, and pretends that the two genera show pollen morphological differences. In the present study the pollen morphology of all ten species of the complex is described on the basis of light and scanning electron microscopy (including examination of broken grains, which were obtained with a technique never applied in palynology, viz. shaking with glass beads). The two genera have 3-zonocolporate grains with compound apertures (endoapertures are always H-shaped, sometimes incompletely so). While Hallea showed to be stenopalynous (sexine always tectate-perforate), Mitragyna is more variable (sexine microreticulate or tectate-perforate), and several of its species have pollen...

To make a meadow it takes a clover and a bee: the entomophilous flora of N.W. Europe and its insects
Provedor de dados: Naturalis Digital Academic Repository
Autores: Ellis, Willem N.; Ellis-Adam, Albertine C.
An analysis of the anthophilous fauna of N.W. Europe is presented, stressing the role plants play for insects. The study is based on some 29,000 relations between about 2,600 insect species and 1,300 plant species (569 genera). The data are derived from our database (“CrypTra”) of biotic relations between Cryptobiota and Tracheophyta, that is based on published sources. It is suggested that a ratio of 2 to 5 anthophilous insect species per entomophilous plant species is the rule in N.W. Europe, where other types of zoophily are virtually absent. A small minority of the plant species/genera play a disproportionally important role as hosts to flower visitors; many of these so-called cornucopian taxa belong to the commonest entomophilous plants in the region,...

Four species have for the first time crossed the border of the Netherlands, while extending their range: Bidens radiata, Bupleurum falcatum, Callitriche brutia, and Scirpus holoschoenus. Possible recent immigrants are Hypericum androsaemum, Leucanthemum paludosum and Polycarpon tetraphyllum. It is unlikely that Cerastium brachypetalum and Helichrysum arenahum are again part of the Dutch flora.

Autores: Rödl-Linder, G.
The present revision deals with the systematics of the genus Polypodiopteris which is endemic to Borneo and is a precursor for the Flora Malesiana treatment of the family Polypodiaceae which will appear in the near future. It includes the recognition, the description and a full synonymy of three species with pectinate fronds, irregularly anastomosing veins, and lacking any soral paraphyses. Certain characters suggest a relationship with the genus Selliguea, but no conclusions can be made before the revision of that genus is finished.

Gulella adami spec. nov. is described from a classical West African locality, Assini in the Ivory Coast (Côte d'Ivoire). It is most unusual in showing two superficial parietal processes, which may also be interpreted as a double angular lamella, in the aperture of the shell. The shell closely resembles that of various Enidae in SE Europe and adjoining areas around the Mediterranean, thereby providing a striking example of convergent evolution.

Cephalopods of the Red Sea, Gulf of Aden and the Western Indian ocean off Somalia are studied. A preliminary annotated list is presented. This study was based on the examination of 381 specimens captured with a Rectangular Midwater Trawl (RMT8) during three cruises of the Netherlands Indian Ocean Programme. The taxa identified represent: 22 families, 35 genera and 56 species. Two species new to science are found. Systematic position and taxonomic re-evaluation in the Chiroteuthidae, Mastigoteuthidae and Octopodidae is briefly discussed. The present collections represent a valuable contribution to the species composition from the Western Indian Ocean and to cephalopod juvenile morphology.

New species of Zyzzya, Cornulella, Damiria, and Acheliderma (Porifera: Poecilosclerida), with a review of fistular genera of Iophonidae
Provedor de dados: Naturalis Digital Academic Repository
Autores: Soest, R.W.M. van; Zea, S.; Kielman, M.
New sponge species belonging to the closely related fistular genera Zyzzya, Cornulella, Damiria, and Acheliderma are described from reef habitats off the coasts of Colombia, Bonaire and Curaçao in the southern Caribbean. With very few exceptions these sponges are small to tiny specimens inhabiting crevices and other cryptic habitats; some may be excavating. For comparison both published and unpublished material belonging to these genera from other parts of the world was examined, and this yielded several nomenclatorial changes and a further three new species from the Indian Ocean. The new species are: Zyzzya invemar (Caribbean), Cornulella santamartae (Caribbean), C. tyro (Seychelles), C. amirantensis (Seychelles), Damiria leonorae (Caribbean), D. toxifera...

A concise history of the botanical collecting and abbreviated reports of the exploration tours by C.G.G.J. van Steenis and De Wilde &amp; Duyfjes in the Gunung Leuser Park and vicinity, northern Sumatra (mainly Aceh Province) is given. This shows that essential areas of the Park, e.g. at the West side, are still botanically unknown. The remarkable achievements in field work by Van Steenis are recorded. The detailed descriptions of the itineraries give a good impression of the constitution and botanical conditions of the terrains of the interior and will be useful for the logistics of future exploration efforts in this difficult and unsurveyable area. The amount of botanical collecting done in the various vegetation types traversed is indicated. The...

Reviews
Provedor de dados: Naturalis Digital Academic Repository
Autores: Schuiteman, André; Koning, J. de.
This book is essentially a much expanded and updated version of Dressier’s well known ‘The Orchids; natural history and classification’ (1981), without the parts on natural history. Dressier divides the orchid family in five subfamilies: Apostasioideae, Cypripedioideae, Epidendroideae, Spiranthoideae, Orchidoideae. The Epidendroideae have swallowed the Vandoideae, which he recognized in his earlier book. At the tribal and subtribal level there are many changes too. Most of these changes reflect increased knowledge and the results of in-dept studies, and are therefore likely to be improvements. The classification proposed is the most thorough and best-argued one currently available. Much is still tentative, however, and even the number of subfamilies and...

The genera Padbruggea Miq., Whitfordiodendron Elmer, and Millettia sections ‘urybotryae’ and ‘ustromillettia’ were united under Callerya Endl. by Geesink (1984). This article presents the necessary new combinations for Callerya sensu Geesink. An outline of the taxonomic history of the genus is given together with some notes on the taxonomic and phylogenetic position. The genus is separated from the remaining bulk of Millettia on account of its thick paniculate inflorescences and diadelphous stamens. A majority also shares conspicuous bracts and bracteoles and a more or less bilaterally symmetric calyx. A key to the nineteen species recognized and full descriptions of the species are provided in the taxonomic part.

Systematic notes on Megapodiidae (Aves, Galliformes), including the description of five new subspecies
Provedor de dados: Naturalis Digital Academic Repository
Autores: Roselaar, C.S.
Megapodiidae (megapodes, brush-turkeys, scrubfowl, and relatives) form a peculiar family within the Galliformes. They show an unusual incubation strategy which shows resemblance to that practiced by reptilians but which is unknown for other bird families: eggs are laid in burrows or in mounds of leaves or other organic debris gathered by the birds, and heat generated by decaying leaves or, in case of burrownesting, heat from geothermal activity or from sunradiation results in hatching of the chicks, providing that a temperature of c. 33°C and a moderate humidity are maintained (Dekker &amp; Jones 1992). Once hatched, the chick struggles to the surface and leaves the hatching-area on the foot or on the wing without its parents paying attention to them. This...

Voor het overzicht van de spreiding van en de aantallen bezochte km-cellen en voor het globale aantal taxa per cel is dit geen probleem. Voor het maken van soortsverspreidingskaartjes kan het echter hinderlijke fouten opleveren. Een bestand van vele honderdduizenden waarnemingen zal nooit foutloos zijn. Het streven is echter wel om het percentage fouten zo klein mogelijk te houden.

Botanical Files on Lettuce (Lactuca sativa). On the chance for gene flow between wild and cultivated Lettuce (Lactuca sativa L. including L. serriola L., Compositae) and the generalized implications for risk-assessments on genetically modified plants
Provedor de dados: Naturalis Digital Academic Repository
Autores: Frietema de Vries, F.T.; Meijden, R. van der; Brandenburg, W.A.
In Botanical Files, a study of the real chances for gene flow from cultivated plants to the wild a system of dispersal codes (Dpdf) was introduced (see text box Dpdf).³7 They are indications of already occurring gene flow from cultivated plants to the wild flora, as can be deduced from herbarium collections and florisdc archives. These codes apply to the Netherlands only. One of the crops of which the real chances for gene flow could not be determined, because of uncertainties regarding the relationship between the cultivated plant and its wild relatives, is Lettuce (Lactuca sativa L.). Its relationship with the wild L. serriola L. is accepted to be very close, but the species are considered to be distinguishable. In a field trial, using 350 specimens from...

Bioconcentration of manganese and iron in Panaeoloideae Sing
Provedor de dados: Naturalis Digital Academic Repository
Autores: Stijve, T.; Blake, C.
According to literature, the manganese content of most basidiomycetes fluctuates between 10 and 60 mg/kg, whereas the iron levels range from 100-500 mg/kg (both expressed on dry weight). The present authors report that bioconcentration of manganese is a distinguishing feature of the Panaeoloideae, as demonstrated by the analysis of 44 collections representing 15 taxons. Carpophores generally contain between 250 and 2500 mg/kg on dry weight, and, with the notable exception of Panaeolus semiovatus, P. antillarum and P. phalaenarum, their iron content is 2 to 3 times lower. This phenomenon was not observed in members of related genera such as Psathyrella and Coprinus.

Sediment samples from the Banda Sea were clustered according to the percentages of the different morphotypes of copepod egg-envelopes they contained. The clustering indicates a geographically distinct cluster determined by the occurrence of higher percentages of a single type of copepod egg envelope. It may be indicative of the influence of Equatorial Indian Ocean surface water, notably in the southwestern part of the Banda Sea that is not affected by upwelling.

Valkruid is een reeds lang uit Drenthe bekende plantesoort. Uit archiefmateriaal en mondelinge overleveringen van oudere Drenthen blijkt dat Valkruid tot in de vijftiger jaren algemeen voorkwam op nog niet ontgonnen, vrij droge tot vochtige heidevelden en heischrale graslanden op een lemige bodem en in blauwgraslanden. In dit laatste terreintype kwam Valkruid vooral voor op de beekdalflank, de overgang van het plateau met heischraal grasland naar het eigenlijke blauwgrasland in het beekdal zelf. Het beheer bestond voorheen veelal uit een combinatie van begrazing, maaien, plaggen en branden. Door een verdere versnippering, het achterwege blijven van traditioneel beheer en de toenemende invloed van zure regen en ontwatering is Valkruid in Drenthe de laatste...

A biosystematic basis for pelagic biodiversity
Provedor de dados: Naturalis Digital Academic Repository
Autores: Spoel, S. van der.
Biodiversity can be considered to be a human appreciation of the biological entity diversity. Diversity can be expressed numerically on the basis of taxa found, but it can also be expressed as the contribution of a specimen to the diversity, for which a formula is proposed. Diversity is the sum of the taxonomic or numerical diversity, and the ecological, genetical, historical, and phylogenetic diversity. Moreover, each group, or larger taxon, has its own characteristic diversity. These types of diversity are considered separately. One formula is tentatively proposed to calculate the overall diversity. Diversity in nature is variable, which is demonstrated in a diagram for comparison with societyinduced diversity changes. Diversity in the pelagic fluctuates...

De Blaugerzen van Akmarijp
Provedor de dados: Naturalis Digital Academic Repository
Autores: Altenburg, Wibe; Wymenga, Eddy.
In the Dutch province of Friesland large areas of Cirsio-Molinietum vegetations still existed in the beginning of the 20th century. Embankment of periodically flooded areas, lowering the water table in these new polders and using fertilizer caused a dramatic decline of this area. Nowadays Cirsio-Molinietum vegetations are extremely rare in the Netherlands and probably in the whole of Western Europe. ‘De blauwgraslanden van Akmarijp’, the largest of the remaining Dutch Cirsio-Molinietum vegetations (c. 100 ha), has from the 1950’s on been set aside as a nature reserve. The data in this paper show that the well-developed Carex panicea/Cirsium dissectum dominated Cirsio-Molinietum vegetations of the first half of this century have for the greater part changed...

Revision of the Archiloa genus complex with description of seven new Archilina species (Platyhelminthes, Proseriata) from the Mediterranean
Provedor de dados: Naturalis Digital Academic Repository
Autores: Martens, Paul M.; Curini-Galletti, Marco C.
Based on morphological and karyological investigations, the genus complex Archiloa sensu Karling (1966) is revised. The group contains seven genera, two of which are here described as new: Archiloa de Beauchamp, 1910, Archilopsis Meixner, 1938, Mesoda Marcus, 1949, Monocelopsis Ax, 1951, Archilina Ax, 1959, Inaloa gen. n., and Tajikina gen. n. The genus Pistrix Marcus, 1951 is synonymized with Mesoda Marcus, 1949. Eleven species are transferred to other genera. Seven new Archilina species are described from the Mediterranean: A. brachycirrus, A. deceptoria, A. etrusca, A. palestinica, A. selenifera, A. biselenifera, and A. caliban. Two distinct “morphs” are recognized within A. endostyla Ax, 1959. The genus Archilina now contains 12 species, 8 of which...

Provedor de dados: Naturalis Digital Academic Repository
Autores: Roos, M.C.
Last year I have reported on the results of a first annual questionnaire sent out to all collaborators in the Flora Malesiana network early 1993, asking information on progress, possible bottlenecks, and the expected date of completion of the manuscript. The present report deals with the results of the second questionnaire, which was circulated early 1994. The response was somewhat lower compared to the first one (c. 80% and 85%, respectively).

Contributions towards a monograph of Phoma (Coelomycetes) — III. 1. Section Plenodomus: Taxa often with a Leptosphaeria teleomorph
Provedor de dados: Naturalis Digital Academic Repository
Autores: Boerema, G.H.; Gruyter, J. de; Kesteren, H.A. van.
Twenty-six species of Phoma, characterized by the ability to produce scleroplectenchymatous pycnidia (and often also pseudothecia) are documented and described. An addendum deals with five atypical species, but which on account of literature data may be related. The following new taxa are proposed: Phoma acuta subsp. errabunda (Desm.) comb. nov. (teleomorph Leptosphaeria doliolum subsp. errabunda subsp. nov.), Phoma acuta subsp. acuta f. sp. phlogis (Roum.) comb. nov., Phoma congesta spec. nov. and Phoma vasinfecta spec. nov. Detailed keys and indices on host-fungus and fungus-host relations are provided and short comments on the ecology and distribution of the taxa are given.

The taxonomy and biogeography of the guttulinervis group of the genus Baeturia Stål, 1866 (Homoptera, Tibicinidae)
Provedor de dados: Naturalis Digital Academic Repository
Autores: Boer, A.J. de.
The guttulinervis group is proposed for a monophyletic group of four northern New Guinean species of the cicada genus Baeturia Stål, 1866. B. guttulinervis Blöte, 1960, is redescribed and three species (B. biroi, B. inconstans, and B. roonensis) are described as new to science. The phylogenetic position of the guttulinervis group, within the genus Baeturia, is discussed. The distribution of shared characters suggests a sister group relationship with the conviva group. A key to the males is provided and a map of distribution is presented.

Autores: サビニアーノ, ナオミ S.; 石橋, 憲一; 弘中, 和憲; 山本, 和夫; SABINIANO, Naomy S.; Ishibashi, Ken-ichi; Hironaka, Kazunori; Yamamoto, Kazuo.
The effect of temperature on the properties of potato starch during storage at 1, 5 and 10 centigrade for 6 months were determined. The Brabender peak viscosity, final viscosity at 92.5 centigrade breakdown, swelling power, solubility and phosphorus content decreased while initial pasting temperature, temperature at peak viscosity and blue value of the starches increased during storage. Phosphorus content was highly correlated with Brabender peak viscosity and breakdown(r =0.92 and 0.82, respectively, p&lt;0.01). Higher rates of decrease in viscosity and phosphorus content occurred at 1 and 10 centigrade during storage....

Relaciones peso seco-talla y volumen-talla en Themisto gaudichaudii, principal anfípodo hiperído del Mar Epicontinental Argentino.
Provedor de dados: Ocean Docs: e-repository of  publications
Autores: Alvarez Colombo, G.L.; Viñas, M.D.
Themisto gaudichaudii, the most abundant and widely distributed hyperiid amphipod in Argentine shelf waters, provides a source of food for several species of economical value such as the anchovy, mackerel, hake, and squid. Predictive dry weight-length and volume-length regression were established in order to provide an indirect estimation of the individual body mass from a measurement of body length. Samples were collected in San Jorge Gulf and fixed with a 4 o/o formaldehyde solution. The possible effect of formaldehyde fixation on dry weight and volume is discussed.

The mothership/dory fishing operation 'Pecheur Breton' spent 13 days fishing at the northwestern submarine promontory of Saya de Malha Bank between 24th February and 14th March 1993. The mothership fished using 12 dories which were equipped with echo-sounders and electric fishing reels. A total of 74.3 tonnes of fish was caught in the depth range of 55 to 130 m. of which the blue spotted jobfish (Pristipomoides filamentosus) represented 80%. The catch rates were observed to decreased with time and could not be attributed to changes in climatic conditions, fishing depth, fishing method or bait type.  The initial biomass of Pristipomoides filamentosus at the northwestern submarine promontory of Saya de Malha Bank was estimated at 76.1 tonnes through...

Chemical and physical investigations of water on a 10 km section of     the Sondu-Miriu river in Kenya were conducted in 1988-1990. They     revealed no significant spatial variation between three sampling     stations. Variation existed between the waters of a floodpool and the     river. Flooding had a general diluting effect on the nutrients. All     the physical and chemical parameters investigated were within     tolerable limits of water quality according to WHO criteria for     drinking water, fisheries and other aquatic life. A total of 22     phytoplankton and 9 zooplankton genera were recorded. The algae     Microcystis (cyanobacteria) and Navicula (diatom) were dominant. Mean     densities were 283 cells or colonies per ml for phytoplankters and...

Provedor de dados: Ocean Docs: e-repository of  publications
Autores: Mwalo, O.M.
The work reported was conducted during the watershed period of 1976 when Nile perch (Lates niloticus) started to replace Haplochromis spp. in dominance in the Nyanza Gulf of Lake Victoria. Seventy four "groups" of Haplochromis species flock obtained from a stock assessment survey of that year were used in the study. The length of fish examined varied between 57 and 237 mm total length, and between 1 and 182 g wet weight, with means of 101.05 mm and 18.53 g respectively. Frequency distribution curves for both sexes were unimodal with a maximum between 70 and 130 mm. The t-test showed that the two sexes came from the same population. Clutch size per fish (mean weight 25.3 g and mean total length 106.7 mm) was 78 eggs. The minimum size at maturity was 89 mm...

Working Group on capital needs and availability in artisanal fisheries: methodology and lessons learned from case studies
Provedor de dados: Ocean Docs: e-repository of  publications
Autores: Kébé, M.; Horemans, B.; Odoi-Akersie, W.
The existing way of financing of artisanal fisheries in West Africa is an element which has received so far few attention during the preparation of development policies. Unfortunately, this lack of knowledge has led to field actions of which the results have often be disappointing. Moreover, the informal sector continues to be the main source of financing of artisanal fisheries and the repayment rate of loans granted by the institutional sector is generally low. On this basis; the Programme for Integrated Development of Artisanal Fisheries in West Africa (IDAF) set up a Working Group on capital needs and availability in artisanal fisheries. Its objectives are: (i) to elaborate a simple but efficient methodology likely to facilitate the identification of...

Data used to generate the Tables and Figures presented in this report are based on logbook returns from the fishing vessels. Readers should, therefore, be aware that figures presented in this report are likely to change in future publications of the Tuna Bulletin once all the data relating to the quarter being reported on becomes available. The initial estimate for the total WIO purse seine tuna catch for the first nine months of 1994 is 176,216 Mt. However, this figure may also be^ revised upwards when trips starting in the third quarter of 1994 and finishing in the fourth quarter are included in the next quarterly Tuna Bulletin of 1994. This compares with 203,797 Mt caught in the first nine months of 1993. Some 2,532 days were fished in the third quarter...

Autores: Hansen, J.E.
Two pelagic cruises were carried out by R/V"Cap.Oca Balda" in the spring of 1988 and the following summer. Anchovy samples were taken in order to increase the knowledge on the differences between two main stocks of the species, inhabiting the Argentine Sea from 35°S southwards, with distributional boundary situated at about 41°S. Length-weight relationships were statistically different among populations. Weight-at-length values calculated for the summer cruise were higher tha sprin estimates, and they were also higher within Northern individuals. The differences were not statistically significant between stocks, but there are reasons to believe that if ages 1 and 6 of both stocks had been represented those differences would have been increased.

The management and directions for future research on Lake Victoria multispecies fisheries
Provedor de dados: Ocean Docs: e-repository of  publications
Autores: Okemwa, E.
A brief review is presented on some of the measures taken to manage Lake Victoria multispecies fisheries. It is suggested that management enforcement is not working. The linkage between research, policy making, industry and artisanal fishery is considered. The paper examines how the whole process of taking management decisions might be modified to take into account the realities of life in the riparian states around the lake and of the complexities and uncertainties of multispecies fisheries. Research and assessment are considered. Understanding the multispecies fisheries and characteristics of contemporary fisheries management are described. Recommendations for future research are given.

Autores: Lung'ayia, H.B.O.
Some aspects of the reproductive biology of the Nile tilapia,     Oreochromis niloticus population in the Nyanza Gulf of lake Victoria,     Kenya were investigated from March to August 1991. The overall sex     ratio was 2.08:1 in favour of males. A variation in sex ratio was     observed with females predominating over males in lengths between 37.5     and 41.0 cm total length. Fecundity ranged from 864 to 6316 eggs with     an average of 2141. The relationship between fecundity (F), and total     length (L) and weight (W) was F=22.755 L super(1.2141); F=177.142 W     super(0.342).

Provedor de dados: Ocean Docs: e-repository of  publications
Autores: Ogwai, C.
The occurrence of ichthyoparasites and their cumulative effects was     observed at the inner Nyanza Gulf region of Lake Victoria. Protozoa,     Nematoda, Cestoda, Crustacea and Trematoda are mentioned. The parasite     fauna and the biocoenology of the hosts were studied and the seasonal     variation in infectivity was observed. Infection in the dams was     prevalent and was 75% at the peak. Some gill infected specimens were     examined between July and February. Infestation rates were higher     during the dry season. Males and juveniles dominated the infected     samples throughout the study period. The distribution pattern of the     hosts was also noted.

Autores: Ogutu-Ohwayo, R.; Twongo, T.; Wandera, S.B.; Balirwa, J.B.
On the basis of observations, it is recommended that 127 mm should be     the minimum mesh size of gillnet permitted on Lakes Victoria and     Kyoga. The minimum length of Nile tilapia (Oreochromis niloticus)     should remain at 28 cm but that of Nile perch (Lates niloticus) should     be increased from 46 cm to 50 cm. The minimum mesh size limit of seine     net for Mukene on Lake Victoria should be 10 mm and fishing for Mukene     should be done using lampara net operated offshore.

Autores: Grandcourt, E.
The mothership/dory fishing operation 'Pecheur Breton' spent 13 days fishing at the northwestern submarine promontory of Saya de Malha Bank between 24th February and 14th March 1993.  The mothership fished using 12 dories which were equipped with echo-sounders and electric fishing reels.  A total of 74.3 tonnes of fish was caught in the depth range of 55 to 130 m. of  which the blue spotted jobfish (Pristipomoides filamentosus) represented 80%.  The catch rates were observed to decreased with time and could not be attributed to changes in climatic conditions, fishing depth, fishing method or bait type.  The initial biomass of Pristipomoides filamentosus at the northwestern submarine promontory of Saya de Malha Bank was estimated at 76.1 tonnes through...

Multigear fishery of Nile perch (Lates niloticus) in the Winam Gulf of Lake Victoria: with special reference to mortality, selection and catch/effort data
Provedor de dados: Ocean Docs: e-repository of  publications
Autores: Manyala, J.O.; Rabuor, C.O.
A survey of multigear fishery of Nile perch (Lates niloticus) in the     Winam Gulf of Lake Victoria indicates that total mortality coefficient     (Z) determined from longline fishery using hook number 6 was double     that of hook number 7. Total mortality coefficient determined from     gillnets and beachseines were lower than those of hooks. The catch per     unit effort (C/f) measured using different criteria indicated an     increase for all gears in 1990 as compared to 1989 except for     gillnets. A two-fold increase in unit effort (f) increased the C/f for     mosquito seines by only 30%. The typical exponential decay of C/f with     increasing f of exploited stock in equilibrium was lacking in the case     of Nile perch in the Winam Gulf.

Preliminary study on the food and feeding habits of Schilbe mystus (Linn., 1762) in River Nyando
Provedor de dados: Ocean Docs: e-repository of  publications
Autores: Omondi, R.; Ogari, J.
Schilbe mystus (butterfish) is one of the "endangered species" of Lake     Victoria, whose fishery was once of commercial importance. The annual     landings have declined from about 400 mt in 1968 to a bare 15 mt in     1991. The average size of the species is smaller than that reported by     Greenwood (1966). During the study, the size range sampled was 11.2 to     25.6 cm fork length with the majority measuring 14.0-15.0 cm FL. The     food and feeding habits of the fish are discussed. Study on the gut     content shows that S. mystus preys mainly on insects with chironomid     larvae as the dominant prey.

The assessment covers hake between 34° and 48°S (Argentina and Uruguay), excluding Golfo San Matías. Total international landings and Argentine catch-at-age and effort data available for the 1983-1991 period allowed an analytical assessment. Tunning of the VPA was made using Laurec-Shepherd analysis and Extended Survivor analysis. The results of these analysis are congruent with the information about the state of the stock. VPA biomass estimates are aound 2.1 and 2.7 mill. Tonnes, which are similar to those calculated through surveys. The Spawning Stock Biomass estimated for 1991 is considered to be within limits where the stock shows stable recruitment. At the present effort level, yield and Spawning Stock Biomass appear to remain stable. Management...

The species, like other members of the Family Sparidae, has a hermaphroditic phase in its sexual development, affecting the population partially during the first period of life. The sexual differentiation mechanisms have been inferred by the way of macroscopic characterization and proportionality of the different stages observed during the first five year classes. The highest proportion of specimens with bisexual gonads is observed during the third year of life: from the macroscopical point of view, both sexes are equally developed or with predominance of the masculine crest; microscopically, both are functional and synchronous. The masculine portion demostrate a normal expulsion of germ cells and in the ovaric part post-ovulatory and atretic follicles...

The age study of fishes using daily growth increments DGI observations is made from: 1- either the exhaustive determination of increments, 2- or the calculation of daily growth increments density for different otolith zones between the nucleus and the margin edge of otolith, the width of increments being presumed constant for each zone. To apply the first method, increments may be readable individually from the nucleus to the margin edge of otolith. This is a very time consuming operation. It can cause miscalculation of increments and errors of the age estimation. The second method, called "DGI density method" is based on the decrease of the increment width in relation to the slowing down of the growth phenomena. The more used approach according to this...

Initial results of the benthic fauna studies in the northern Lake Victoria
Provedor de dados: Ocean Docs: e-repository of  publications
Autores: Mbahinzireki, G.B.
The paper presents initial results of relative abundance, composition     and distribution of benthic organisms in an ecologically and     environmentally changing northern Lake Victoria. The results suggest     that the density of most of the zoobenthos has gone up since the     pre-perch era despite the absence of comparative data. Increases in     densities were noted for dipteran larvae followed by Caridina     nilotica, ostracods, oligochaetes, molluscs and nymphs of Anisoptera     and Ephemeroptera, in that order. Possible reasons to account for the     increase are advanced. Inshore stations held higher densities than the     offshore station. Type of the sediment and physico-chemical factors     seem to influence the production and distribution of...

Ecological changes in Lake Victoria after the invasion of Nile perch (Lates Niloticus): the catchment, waters quality and fisheries management
Provedor de dados: Ocean Docs: e-repository of  publications
Autores: Ochumba, P.B.O.; Goshen, M.; Pollinger, U.
Lake Victoria, the second largest lake in the world, has undergone     successive dramatic changes since 1920's. Intensive non-selective     fisheries, extreme changes in the drainage basin of vegetation,     industrialization, agricultural developments, dams, introduction and     invasion of exotic fish species that led to the destruction of the     native and endemic components followed by a progressive build-up of     physical and chemical changes in Lake Victoria have identified     substantial increases in chlorophyll concentration and primary     productivity as well as decreases in silica compared to values     measured 30 years ago. Present sulphate concentration (0.1 mg/L) are     lower than the lowest values reported from other large lakes in the...

The aim of this paper is to discuss the validity of the taxonomic status formerly assigned to the rough scad inhabiting shelf waters off Buenos Aires Province, Argentina. Until recently the species had been considered, mainly by Argentine authors, as Trachurus picturatus australis, on the basis of a description by Nani (1950). Other authors, however, consider that the only valid species for the West Atlantic is Trachurus lathami. In general terms, there references are based on rather scarce material for this region. In this paper, we compare meristic and morphometric data from 160 specimens collected off Mar del Plata. Statistical analysis of the characteristics lead us to conclude that the valid scientific name of the Argentine rough scad is Trachurus...

Due to the inclusion of trips which started at the end of 1993 but which finished in early 1994 the 1993 total catch for the WIO has been revised upwards from 263,918 MT, published in the last Tuna Bulletin, to 275,058 MT. The initial estimate for the total WIO purse seine tuna catch for the first three months of 1994 is 61,159 MT (the figure of 70,000 MT published in the Globefish Bulletin 2/94 was based on an early estimate).  However, this figure may also be revised upwards when trips starting in the first quarter of 1994 and finishing in second quarter are included in the next quarterly Tuna Bulletin of 1994.

Floodplain fishery of the lower Sondu-Miriu River with emphasis on the Nile perch (Lates niloticus) (Linnaeus)
Provedor de dados: Ocean Docs: e-repository of  publications
Autores: Manyala, J.O.
Experimental beach seine surveys in 1990 in the lower Sondu-Miriu     River in Kenya indicate a potential catch rate of up to 59.8 kg ha     super(-1) hr super(-1). Lates niloticus dominated the catches in the     lower reaches (37.5%), while catches in the upper reaches were     dominated by Labeo victorianus, Schilbe mystus and Barbus altianalis.     L. victorianus contributed up to 84.8% of the catch in the upper     reaches by weight. Catches in the floodplain were dominated by     Oreochromis niloticus, O. variabilis and Clarias gariepinus, which     contributed more than 50% by weight. The size frequency distribution     of L. niloticus suggests that larger specimens occur in the river as     compared to the floodplain.

Florecimiento de microalgas relacionado con mortandad masiva de peces en el complejo lagunar Ciénaga Grande de Santa Marta, Caribe colombiano
Provedor de dados: Ocean Docs: e-repository of  publications
Autores: Mancera-P., José E.; Vidal-V., Luis A.
Entre los meses de julio y agosto de 1994 un fenómeno discontinuo de muerte masiva de peces se registró en aguas del complejo lagunar de la Ciénaga Grande de Santa Marta, Colombia. El primer evento se presentó del 15 al 19 de julio, el segundo alrededor del día 20 de agosto y el tercero entre el 26 y 31 del mismo mes. La presencia en altas concentraciones de la cianofita filamentosa Cf. Anabaenopsis sp., registrada en la literatura como altamente tóxica, podría estar relacionada con las causas del primer evento. Un incremento en las concentraciones de fósforo, y un posterior florecimiento de nano y picoplancton, especialmente cianofíceas y algas flageladas, explicaría en parte las condiciones hipóxicas y anóxicas observadas en el tercer evento, las cuales...

Preliminary Resource Assessment of Yellowfin Tuna (Thunnus Albacares) in the Western Indian Ocean by the Stock-Fishery Dynamic Model
Provedor de dados: Ocean Docs: e-repository of  publications
Autores: Nishida, T.
Yellowfin tuna (Thunnus albacares, YFT) in the Indian Ocean has been exploited for more than 200 years (Anderson and Hafiz, 1985), while official statistics are available for some 40 years. In this region, the YFT resource has been commercially important as a protein source for both developing and developed countries. Hence, it is essential to manage and conserve YFT resources properly for future generations. To this end, an assessment of the YFT stock is presented in this paper, in order to provide fundamental information for its management. More than 80% of the YFT catch from the Indian Ocean comes from the western part (Figure 1), so this assessment is focused on that part. In this study, the stock structure of the Indian Ocean YFT is assumed to be two...

Oreochromis niloticus forms the third most important commercial     fishery in Lake Victoria after Lates niloticus and Rastrineobola     argentea. Because of its commercial importance as a cheap source of     animal protein, a study of its landing trends, growth and mortality     rates was conducted to assess the state of its stock in the lake and     recommend guidelines for its exploitation and management. To arrive at     the trends, landing data between 1976 and 1989 were analysed. For the     estimation of the growth and mortality rates, length frequency data     were collected from trawl surveys conducted fortnight between     Sseptember, 1989 and August, 1990 in the Nyanza Gulf. The results show     increased landings during the study period, with a...

The age study of fishes using daily growth increments DGI observations is made from: 1- either the exhaustive determination of increments, 2- or the calculation of daily growth increments density for different otolith zones between the nucleus and the margin edge of otolith, the width of increments being presumed constant for each zone. To apply the first method, increments may be readable individually from the nucleus to the margin edge of otolith. This is a very time consuming operation. It can cause miscalculation of increments and errors of the age estimation. The second method, called "DGI density method" is based on the decrease of the increment width in relation to the slowing down of the growth phenomena. The more used approach according to this...

Bathymetric changes in groundfish catch composition are analyzed, on the basis of routine reports of 106 bottom longline strings. The project was conducted from 12 December 1986 to 29 November 1987, covering areas from coastal waters to the outer shelf of the continental shelf off Argentina from 36° to 55°S. As a preliminary step to the analysis, the validity of each factor as probable explanatory variable in each area, was analyzed with consideration as to their range and variation. Obtained results show that the kingclip (Genypterus blacodes), a main objective of the project, could become one of the most profitable target species of the high-sea bottom longline, in areas along the outer edge of the continental shelf, at bottom depths slightly below 200...

Low nutrient availability is not the single factor limiting &lt;i&gt;Artemia&lt;/i&gt; cyst productivity in salinas of NE-Brazil
Provedor de dados: Open Marine Archive
Autores: Camara, M.R.; Tackaert, W.
&lt;i&gt;Artemia&lt;/i&gt; production in NE-Brazil began in 1977 after a successful inoculation of &lt;i&gt;Artemia franciscana&lt;/i&gt; (San Fransisco Bay, California, USA) in solar salt ponds in Macau (RN state) and was followed by a rapid natural dispersion of this crustacean to all saltwork areas in the region. &lt;i&gt;Artemia&lt;/i&gt; is basically produced in extensive conditions as an opportunistic by-product collected from salt evaporation ponds. This type of approach has, however, brought about very unpredictable results, as is reflected in a drastic decline of cyst production occurring from 1982 onwards. Low nutrient concentrations and a drop in primary productivity have been suggested as possible causes for this decline. In order to provide a...

De Belgische staatshervorming en het Zeerecht
Provedor de dados: Open Marine Archive
Autores: Franckx, E.
Belgium became officialy a federal state in 1993. The federal competence was reshuffeled and parts of it attributed to the Communities and Regions. Since the latter became competent in economic matters, it is mostly the redistribution of powers between the federal and regional level which is at order in this study. At first sight, a rather simple rule of thumb can be applied. All waters located on the land-side of the baseline, i.e. the low-water line in Belgium, belong to the competence of the Regions. All waters on the seaside of the baseline, on the other hand, remain a federal competence. This is the result of a basic interpretation given by the Conseil d’Etat in 1976. This body reached the conclusion that the territorial sea did not form part of the...

Autores: Verdonck, L.; Swings, J.; Kersters, K.; Dehasque, M.; Sorgeloos, P.; Léger, P.
Samplings were organized in three marine fish hatcheries. Samples were taken at different steps during the production of algae, rotifers and &lt;i&gt;Artemia&lt;/i&gt; . There were 233 dominant colony types isolated for further characterization. The isolates were compared to each other and to reference strains of &lt;i&gt;Photobacterium, Vibrio&lt;/i&gt; and &lt;i&gt;Alteromonas&lt;/i&gt;, using cellular fatty acid fingerprints. Fatty acid profiles of the isolates were grouped using principal component analysis. The isolates fell into at least ten major groups, of which two correspond to the genera &lt;i&gt;Vibrio&lt;/i&gt; and to &lt;i&gt;Alteromonas&lt;/i&gt;, respectively. Some groups seem to be restricted to a particular type of live food or isolation...

Grain size trends associated with net sediment transport patterns: an example from the Belgian continental shelf
Provedor de dados: Open Marine Archive
Autores: Gao, S.; Collins, M.B.; Lanckneus, J.; De Moor, G.; Van Lancker, V.R.M.
Grain size trends in relation to net sediment transport pathways are examined, using some commonly-used grain size parameters. The results of the trend analysis (for 15 types of the trends) are compared with a known  net sediment transport pathways established on the basis of the sandbank hydro- and sediment-dynamics (i.e. general water and sediment movement patterns and bedform asymmetry). It is shown that: (1) the results for grain size trends associated with "a worsening in sorting along the transport pathways" have little similarity to transport pathways; (2) the results for grain size trends associated with "an improvement in sorting along the transport pathways" have relatively high degree of similarity to the identified pathways; and (3) the...

Autores: Rees, J.F.; Curé, K.; Piyatiratitivorakul, S.; Menasveta, P.; Sorgeloos, P.
&lt;i&gt;Penaeus monodon&lt;/i&gt; postlarvae (PL-5) were reared for 10 days on &lt;i&gt;Artemia nauplii&lt;/i&gt; enriched with various levels (2.65, 5.30, 12.60, 22.35 and 31.20 mg/g DW) of (n-3) highly unsaturated fatty acids (HUFA). On day 5 and 10, their resistance to osmotic shocks (transfer from 30 ppt to 0, 5, and 10 ppt diluted seawater) was analyzed. After 5 days, postlarvae fed &lt;i&gt;Artemia&lt;/i&gt; containing 12.6 mg/g (n-3)HUFA or more had a significantly higher resistance (p&lt;0.05) than controls. Five days later, no significant difference could be detected among the treatments. A positive correlation was found between the stress resistance of PL-10 and the survival recorded five days later in each tank (p&lt;0.02). It is concluded that...

Air sampling on a series of 10 cruises, spanning the whole area of the North Sea, yielded detailed spatial distributions of atmospheric concentrations of Al, Si, S, Cl, P, K, Ca, Ti, V, Cr, Mn, Fe, Ni, Cu, Zn, and Pb determined by EDXRF. A strong influence of the air mass history on the heavy metal concentrations was demonstrated for the whole sampling period of 5 years. Factor analysis performed on all samples collected with a stack filter unit resulted in the identification of three factors for the coarse particle fraction (sulphate particles with trace metals, sea salt particles and soil dust or metallurgic particles containing Fe) and four factors for the fine particle fraction (sea salt, sulphate with Pb and Zn), trace metal particles with Cu, Ni, Zn...

A new species of &lt;i&gt;Umalgillid rhabdocoel&lt;/i&gt; is described from echinoids from the Kenyan coast. &lt;i&gt;Syndesmis longicanalis&lt;/i&gt; sp.nov. is found in the intestine of both &lt;i&gt;Tripneustes gratilla&lt;/i&gt; and &lt;i&gt;Toxopneustes pileolus&lt;/i&gt; collected near Mombasa. The most stricking characteristic, which distinguishes the new species from all known species of the &lt;i&gt;Syndesmis-Syndisyrinx&lt;/i&gt; group is the very long scelotic bursal canal and the three ventral glandular papillae. A more detailed comparison between the specimens from the two different hosts demonstrates that they belong to the same species although some differences are statistically significant.

Effect of temperature on the uptake of copper by the brine shrimp, &lt;i&gt;Artemia franciscana&lt;/i&gt;
Provedor de dados: Open Marine Archive
Autores: Blust, R.; Van Ginneken, L.; Decleir, W.
The effect of temperature on the uptake of copper by the brine shrimp &lt;i&gt;Artemia franciscana&lt;/i&gt; has been studied in chemically defined saltwater solutions. Animals were acclimated to temperatures ranging from 10°C to 35°C and exposed to copper at different temperatures within this range. The results show that within each temperature acclimation group, copper uptake increases with increasing temperature of exposure. Within each temperature acclimation group most of the variation can be related to the combined effect of temperature on the chemical speciation and diffusion rate of copper in the diffusion layer lining the exchange surfaces. The magnitude of the apparent activation energy for copper uptake indicates that it is a facilitated...

The harbour seal, &lt;i&gt;Phoca vitulina&lt;/i&gt;, in the Oosterschelde: decline and possibilities for recovery
Provedor de dados: Open Marine Archive
Autores: Mees, J.; Reijnders, P.J.H.
Within the timespan of a few decades, the harbour seal almost completely disappeared from the estuaries in the south-west of the Netherlands. In 1960 a population of around 350 animals still lived in the Oosterschelde and Westerschelde area. About a quarter of this population lived in the Oosterschelde. At present less than 17 animals can be regularly observed in the whole area. Human influences are responsible for the rapid decline of the population. Initially the high hunting pressure and later environmental pollution are the main causes. Loss of habitat and disturbance at the resting places are additional important factors. The Oosterschelde still is a suitable habitat for seals. A short term natural development of a viable population in the area is not...

Autores: Triantaphyllidis, G.V.; Pilla, E.J.S.; Thomas, K.M.; Abatzopoulos, T.J.; Beardmore, J.A.; Sorgeloos, P.
We present evidence that incubation of brine shrimp &lt;i&gt;Artemia&lt;/i&gt; encysted embryos (cysts) at high temperatures (36-37°C) suppresses hatching of cysts from a parthenogenetic population, while at the same time allowing cysts of the New World bisexual species (&lt;i&gt;A. fransiscana&lt;/i&gt;) to hatch. This approach is used to verify the presence of contaminating foreign material from the New World in natural cyst populations of Old World &lt;i&gt;A. parthenogenetica, A. sinica, A. urmiana&lt;/i&gt; and &lt;i&gt;A. tunisiana&lt;/i&gt;.

Living in the twilight: estimating net phytoplankton growth in the Westerschelde estuary (The Netherlands) by means of an ecosystem model (MOSES)
Provedor de dados: Open Marine Archive
Autores: Soetaert, K.; Herman, P.M.J.; Kromkamp, J.
Net phytoplankton productivity in the Westerschelde, a relatively deep. highly turbid and eutrophic estuary in the Southwest Netherlands, was examined by means of a 13-compartment dynamic simulation model. The description of the light-Iimited primary production was based on the model of Eilers and Peeters (1988. &lt;i&gt;Ecol. Model.&lt;/i&gt;, 42, 185-198). This light limitation was parameterized to the different model compartments by integrating the Eilers-Peeters model over a day and over depth taking into account the morphology of the Westerschelde compartments, the daily fluctuating light regime and characteristics of the photosynthesis-Iight curves of the phytoplankton community. The availability of light to the phytoplankters limited primary...

Annual dynamics of meiobenthic communities in the Ligurian Sea (northwestern Mediterranean): preliminary results
Provedor de dados: Open Marine Archive
Autores: Danovaro, R.; Mees, J.; Vincx, M.
The dynamics of meiobenthic community were investigated on sandy sediments of the pilot station of Zoagli (Ligurian Sea) between January 1991 and January 1992. Meiofaunal densities ranged between 447 (April) and 3421 (July) ind./10 cm2. Nematodes were the dominant group comprising on the average 75 % of the total fauna. Harpacticoid copepods were the second most abundant group (from 1.7 to 55.3 %) followed by Turbellaria (on the average 5.5 % of total fauna) and Polychaeta (on average 1.2 % of total fauna). The importance of several environmental parameters (such as total organic matter, grain size and RPD depth) in structuring the meiobenthic community is discussed.

Plankton size distributions and trophic relations before and after the construction of the storm-surge barrier in the Oosterschelde estuary
Provedor de dados: Open Marine Archive
Autores: Tackx, M.L.M.; Herman, P.M.J.; Van Rijswijk, P.; Vink, M.; Bakker, C.
Phytoplankton and zooplankton biomass distributions were calculated on a carbon basis for the inland part of the Oosterschelde, in the period before (1983), during (1984, 1986) and after (1987, 1988) the construction of the storm-surge barrier. In all years studied, both phytoplankton and zooplankton distributions are very irregular, and little consistent patterns emerge. The data were used to test the model of Sheldon et al. (1977). The observed standing stock ratios of zooplankton to phytoplankton agree with the model predictions in 1983, and are slightly higher during the period 1984-1987. In 1988, the model predictions are very different from the observed values, because of important changes in the zooplankton species abundance occurring in this year.

Changes in the fish fauna of the Oosterschelde estuary: a ten-year time series of fyke catches
Provedor de dados: Open Marine Archive
Autores: Hamerlynck, O.; Hostens, K.
Frequency of occurrence of fish species was monitored on a fortnightly basis in four fykes and a weir in the Oosterschelde estuary from 1979 through 1988. This was done in order to record changes in the fish fauna that may have occurred as a response to the construction of a storm-surge barrier in the mouth of the Oosterschelde (1984-1986) and the concomitant building of compartmentalization dams in the landward part. These compartmentalization dams reduced the freshwater inflow into the system. Principal component analysis using the annual averages in frequency of occurrence suggests a slight shift occurred in the fish community separating a cluster of years 1979-1984 from the cluster 1985-1988. Many of the changes in individual species could be...

A study of &lt;i&gt;Heterocucumis steineni, H. denticulata&lt;/i&gt; (Ekman, 1927) and &lt;i&gt;Staurocucumis liouvillei&lt;/i&gt; (Vaney, 1914) shows that the main ossicle change occurs early when specimens are 20 mm long or even less. A review of holothurian ossicle variation is given.

Two producers are described for the solid-phase extraction of ascorbic acid 2-sulfate from cysts of the brine shrimp &lt;i&gt;Artemia&lt;/i&gt; . The first one is based on reversed-phase ion pair extraction on an octadecylsilica cartridge using tetrabutylammonium as the counterion, followed by elution with methanol. In the second procedure ascorbic acid 2-sulfate is retained on a DEAE silica cartridge and eluted with 0.1M sodium salicylate. Both approaches were used as part of a quantitative reversed-phase ion pair liquid chromatographic method with detection at 254nm. The anion exchange extraction procedure is superior to its ion pair counterpart in terms of recovery (88.7±3,5% versus 63.0±12.7%), reproducibility (CVs of 3.6-7.7% versus 6.3-18.7%), and...

An oral challenge for turbot larvae with &lt;i&gt;Vibrio anguillarum&lt;/i&gt;
Provedor de dados: Open Marine Archive
Autores: Chair, M.; Dehasque, M.; Van Poucke, S.; Nelis, H.; Sorgeloos, P.; De Leenheer, A.P.
There is a need for a standard in vitro procedure to infect larval fish with bacteria. Such a procedure could be used as a tool to evaluate fish quality, verify fish sensitivity to a certain bacterial strain or evaluate the pathogenicity of a bacterium towards a given fish species. The availability of a challenge test is a prerequisite in studies dealing with the effect of different medicinal treatments on diseased fish. An oral challenge test would offer the possibility to investigate the routes of infection via the digestive tract, i.e. after feeding contaminated feeds. The present study aims to verify this hypothesis and proposes a standard challenge procedure for turbot (&lt;i&gt;Scophthalmus maximus&lt;/i&gt;) larvae with a pathogenic &lt;i&gt;Vibrio...

Fish species of the lower Zeeschelde (Belgium): a comparison with historical checklists
Provedor de dados: Open Marine Archive
Autores: Van Damme, P.A.; Hostens, K.; Ollevier, F.P.
In the 19th century approximately 40 fish species (excluding freshwater species) were recorded in the lower Zeeschelde between the Dutch/Belgian border and Antwerpen. In comparison with the 19th century and the first half of the 20th century the total number of fish species in the Beneden-Zeeschelde has decreased considerably. The present checklist (1991-1993) of fishes of the lower Zeeschelde (excluding freshwater species) contains only 26 species. The fish community is composed of marine species (13), catadromous species (3), estaurine residents (9) and one anadromous fish species. Besides, 6 freshwater fis species have presently been recorded. The distribution of diadromous fishes, estaurine residents and freshwater fishes is probably greately affected...

Effect of lipid supplementation on growth, survival and fatty acid composition of bivalve larvae
Provedor de dados: Open Marine Archive
Autores: Coutteau, P.; Caers, M.; Mallet, A.; Moore, W.; Manzi, J.J.; Sorgeloos, P.
Lipids, particularly triglycerides, play an important role in early life stages of bivalves as a source of energy and essential fatty acids. Ingestion and incorporation of the fatty acids supplied through lipid emulsions were verified analytically for larval oysters &lt;i&gt;Ostrea edulis&lt;/i&gt;. Changes of the fatty acid composition, in particular of (n-3) highly unsaturated fatty acids (n-3 HUFA), were demonstrated in total lipids, polar lipids and triglycerides of oyster larvae fed the lipid emulsions as a supplement to &lt;i&gt;Isochrysis galbana&lt;/i&gt; (clone T-Iso), and were dependent on the level and proportion of (n-3) HUFA present in the emulsion. Preliminary culture trials with &lt;i&gt;Mercenaria mercenaria&lt;/i&gt; showed better growth...

Autores: Sorgeloos, P.
Much progress has been made in the last decades in the industrial farming of several species of marine fish. The pioneering country has been Japan with the red seabream, however, in the last decade Europe made quick progress with seabass and gilthead seabream. Today Japan is still the biggest producer of marine fish fry with about 200 million fry per year, 70% of the production consisting of red seabream and Japanese flounder. Without any doubt, the most significant progress achieved during the last decade has been the result of improved nutrition, more particularly through the manipulation of the fatty acid profile of the live preys &lt;i&gt;Brachionus&lt;/i&gt; and &lt;i&gt;Artemia&lt;/i&gt; by application of enrichment or boosting techniques with...

The development of a cost-effective algal substitute would greatly reduce the operating costs of bivalve hatcheries. Previous work has resulted in the development of a yeast diet with improved digestibility and nutritional composition. The use of this yeast product as a partial algal substitute for the culture of juvenile hard clams &lt;i&gt;Mercenaria mercenaria&lt;/i&gt; was investigated in a series of growth experiments. Juveniles of the hard clam (1 mg live weight) were batch cultured in a 1 8 1 recirculating system for 2 or 3 weeks.

&lt;i&gt;Penaeus monodon&lt;/i&gt; postlarvae (PL-5 to PL-15) were fed 5 different diets consisting of enriched &lt;i&gt;Artemia nauplii&lt;/i&gt; with a specific n-3 HUFA content. Although the postlarvae grew well on an &lt;i&gt;Artemia&lt;/i&gt; diet with low HUFA-content, the ability of PL-10 to endure osmotic stress remained low. Feeding &lt;i&gt;Artemia&lt;/i&gt; enriched with medium levels of n-3 HUFA (sum n-3 HUFA =12,55mg/g DW) for 5 days considerably enhanced the resistance of PL-10 to osmotic stress and their survival recorded 5 days later. However, very high dietary levels of n-3 HUFA (31,2 mg/g DW) did not have any growth promoting effect, thus suggesting that an excessive supply of n-3 may not be beneficial to the shrimp.

Nekton communities of an intertidal creek of an European estuarine brackish marsh
Provedor de dados: Open Marine Archive
Autores: Cattrijsse, A.; Makwaia, E.S.; Dankwa, H.R.; Hamerlynck, O.; Hemminga, M.A.
The utilization of an estuarine brackish marsh in the Westerschelde estuary (southwest Netherlands) by fish and crustaceans visiting the intertidal creeks at rising tides was investigated over an 18 mo period. Samples were collected every month over a tidal cycle. A stow net passively fished the nekton migrating in and out of the marsh habitat. Simultaneous measurements of current speed and waterheight allowed for quantification of the catches. Multivariate clustering and ordination techniques were applied to assess temporal changes in the nekton assemblage. A total of 68 fish and crustacean species were caught but only 38 were regular visitors of the marsh creek. The marsh nekton community proved to have a very stable character. Only 40% of the observed...

Evidence for the induction of cyst diapause by heat-shock in &lt;i&gt;Artemia&lt;/i&gt; (International study on &lt;i&gt;Artemia&lt;/i&gt;: 48)
Provedor de dados: Open Marine Archive
Autores: Abatzopoulos, Th.; Triantaphyllidis, G.; Sorgeloos, P.; Clegg, J.S.
The brine shrimp &lt;i&gt;Artemia&lt;/i&gt; produces embryos (cysts) in a state of obligate dormancy called diapause. Diapause is terminated by a variety of treatments, including dehydration. Previous work suggested that some cysts can be induced to reenter diapause when exposed to prolonged anoxia. Results presented in this paper indicate that heat shock (42-43°C) can also lead to diapause induction. The basis for this proposal is the finding that the final hatching level of heat-shocked cysts is increased by a post-heat dehydration, a treatment known to terminate diapause. The respiration rate of postheat-shocked cysts was found to be much lower than controls. Electrophoretic profiles of proteins in extracts from control and heatshocked cysts suggest...

Subsidence in coastal lowlands due to groundwater withdrawal: the geological approach
Provedor de dados: Open Marine Archive
Autores: Baeteman, C.
The vulnerable situation of coastal lowlands with respect to flooding is aggravated by land subsidence due to groundwater withdrawal. Because of the growing demands of the ever increasing population, industry and tourism, excessive and uncontrolled pumping is the order of the day in most of the great coastal cities. Therefore, well-balanced groundwater management has become imperative for the survival of these sinking cities. Groundwater management implies geotechnical and hydrogeological research. The geological data, however, still form the basic framework, but geological data can only be useful if the three-dimensional spatial extension of relevant units is delineated. The elaboration of the geometry based on the knowledge of processes responsible for...

The meiobenthic fauna of the Westerschelde, a highly polluted and physically disturbed estuary in the south-west Netherlands, was investigated. Samples were taken in spring from six transects, including the intertidal, subtidal and channel area, and located along the salinity gradient. The samples were subdivided into slices to examine the vertical distribution of meiobenthos. Meiobenthos densities were higher in the intertidal than in most permanently submersed areas; the subtidal sites below 7 salinity were nearly devoid of meiobenthic life. Nematodes were by far the most abundant meiobenthic organisms in the intertidal, but were less dominant in the other areas. Gastrotrichs, turbellarians, copepods and large ciliates were usually more numerous in the...

One foot in the grave: zooplankton drift into the Westerschelde estuary (The Netherlands)
Provedor de dados: Open Marine Archive
Autores: Soetaert, K.; Herman, P.M.J.
The net growth rate of marine zooplankton entering the Westerschelde estuary was investigated using an advective-dispersive transport model that simulates zooplankton biomass behaving conservatively in the estuary. Total biomass of marine zooplankters in the Westerschelde was much lower than what would be expected based on transport alone, indicating negative growth rates in the estuary. Including a net consumption term in the transport model allowed the estimation of total net mortality. About 3% of all marine zooplankters that enter the Westerschelde with the flood currents are retained in the estuary, where they die. On average, 5% of the total marine zooplankton biomass in the estuary died per day. Each year a net amount of about 1500 t of zooplankton...

Vertical profiles of SO&lt;sub&gt;2&lt;/sub&gt; and O&lt;sub&gt;3&lt;/sub&gt; concentrations were measured continuously within the lower atmosphere during 18 flights over the Southern Bight of the North Sea. The average SO&lt;sub&gt;2&lt;/sub&gt; concentration below the temperature inversion layer ranged from 1.9 to 19.5 ppb. The highest levels were observed when the air masses came from the southeast-east and under variable wind sector conditions: 15.2 and 12.0 ppb, respectively. The highest SO&lt;sub&gt;2&lt;/sub&gt; concentrations were found at altitudes between 100 and 200 m. The overall average O&lt;sub&gt;3&lt;/sub&gt; concentration was 46 ppb, with values of 30-40 ppb at sea level to 60-70 ppb at altitudes above 100 m. Low O&lt;sub&gt;3&lt;/sub&gt;...

The mobile epifauna of the soft bottoms in the subtidal Oosterschelde estuary: structure, function and impact of the storm-surge barrier
Provedor de dados: Open Marine Archive
Autores: Hostens, K.; HamerlyncK, O.
Data on the mobile epifauna of the Oosterschelde estuary, collected by beam trawl, were compiled from several studies. Multivariate statistical techniques brought out the fact that the Oosterschelde, when compared with neighbouring areas, has a characteristic epibenthic fauna. Diversity as measured by Hill's diversity numbers N through N &lt;sub&gt;+infinite&lt;/sub&gt;, is higher for the Oosterschelde (N&lt;sub&gt;1&lt;/sub&gt;=4.5) than for the Voordelta (N&lt;sub&gt;1&lt;/sub&gt;=3.5) and the Westerschelde (N&lt;sub&gt;1&lt;/sub&gt;=2.2).Four epifaunal communities can be distinguished within the Oosterschelde, the two most seaward communities being the richest. Annual production is estimated at about 6 gADW m&lt;sup&gt;-2&lt;/sup&gt;...

Individual aerosol particle composition variations in air masses crossing the North Sea
Provedor de dados: Open Marine Archive
Autores: De Bock, L.A.; Van Malderen, H.; Van Grieken, R.
Single-particle analysis on North Sea and rainwater samples was performed by electron-probe X-ray microanalysis (EPXMA). The analysis was mainly focused on the determination of the inorganic composition of giant particles with diameters above 1 µm. Multivariate techniques were used for the reduction of the data set and for source apportion. Based on the relative abundances found by hierarchical cluster analyses according to the Ward error sum method, three to eight different aerosol types were distinguished. Crossing the North Sea, the changes in air mass composition appeared as a decrease in the abundance for the aluminosilicate particles and relative increase for NaCl and seawater crystallization products. Principal factor analysis revealed four...

Sprays Used in Ecological Agriculture: Potential and Constraints for Use
Provedor de dados: Organic Eprints
Autores: Znaor, Darko.
Due to the benefits of diversity, autonomous ecosystem management and careful farmers' stewardship, pest and disease control doesn't pose a profound problem in ecological agriculture practice. However, during the conversion period, and in ecological horticulture, particularly in fruit growing, this preventive control is often not sufficient enough, and additional control, mostly (curative) spraying is needed. This need for additional pest and disease control (spraying) in ecological horticulture, may be linked with our incomplete understanding of the role of those subsystems in the agro-ecosystem as a whole.     Currently, organic standards normally do specify permitted (environmental friendly, mainly natural substances), prohibited (synthetic pesticides),...

Seeing the positive and negative effects of current agricultural practices,which replaced those used for thousands of years,  has allowed to search and, as a result, developing new ways of operating, new ideas, approaches and global considerations.    Liebig's ideas have been applied in limited profitability approaches and little considerations of sustainability of ecosystems or crop quality have been made(just remember about some military synthesized products during the great wars which were later used in agriculture as fertilizers or pesticides looking for new "markets"). We must resume some management issues such as organic matter, rotations or mineral contributions which are defended by the "law of the minimum".    Under this framework, the Spanish...

Energy use in crop production on danish mixed farms: Systems modelling of data from farm studies
Provedor de dados: Organic Eprints
Autores: Halberg, Niels; Kristensen, Erik Steen; Refsgaard, Karen.
The problems of balancing agricultural production methods against environmental concern cannot be solved by focusing on single activities of livestock farming and experimental knowledge alone because of interactions between herds and crops and between the production system and the manager. An alternative method based on studies in private farms is proposed to evaluate the effects of the production intensity on pollution and resource efficiency. Energy use and crop yield in gram and grass-clover crops registered on conventional and organic mixed dairy farms were analyzed in order to facilitate modelization of energy efficiency in different production systems on different danish soil types. The energy efficiency was higher in organic crops on all soil types...

Autores: Vartdal, Barbro; Løes, Anne-Kristin.
Conversion to organic agriculture as a process of social adaptation was qualitatively analysed by the sociologists Barbro Vartdal and Arild Blekesaune during 1990-92. Altogether, 33 farmers were analysed, giving the sociologists interviews, written diaries or reports as material. The farmers participated in the "30 farm-project", conducted by the Norwegian Centre for Ecological Agriculture. The sociologists described three categories of eco-farmers, according to whether the farmer was cosmopolitically or locally orientated: The antroposopher,the ecosopher and the reformist. Their motivations of farming, conversion and mastering strategies as well as social barriers for conversion were described. It is argued that conversion is a social process as well as a...

Resistência de plantas daninhas aos herbicidas
Provedor de dados: Planta Daninha
Autores: Christoffoleti,Pedro J.; Victoria Filho,Ricardo; Silva,Clóvis B. da.
A resistência de plantas daninhas aos herbicidas ocorre em função de um processo evolutivo. O desenvolvimento de biótipos de plantas daninhas resistentes é imposto pela agricultura moderna, através da pressão de seleção causada pelo uso intensivo dos herbicidas. O conhecimento dos mecanismos e fatores que favorecem o aparecimento de biótipos de plantas daninhas resistentes é fundamental para que técnicas de manejo sejam utilizadas no sentido de evitar ou retardar o aparecimento de plantas resistentes em uma área. São poucos os relatos ou citações de literatura no Brasil. Sendo assim, este trabalho de revisão procura relatar os principais avanços e descobertas na área de plantas daninhas resistentes aos herbicidas.

A losna (Artemisia verlotorum) é uma planta daninha com alta capacidade de rebrota de seus rizomas e tolerante à maioria dos herbicidas, principalmente os de contato, o que dificulta consideravelmente o seu controle químico e mecânico. O 2,4-D, na dose de 1,662 kg/ha (por interpolação), reduziu o número de plantas vivas de losna de 34 para 6 aos 30 dias após sua aplicação, enquanto que, o glifosate, na dose de 0,856 kg/ha, reduziu esse número de 27 para 10. O glifosate, na dose de 0,811 kg/ha, aos 60 dias após a sua aplicação, reduziu o número de plantas vivas de losna de 34 para 18, enquanto o 2,4-D não mais apresentou efeito.

Potencial alelopático de 2-benzoxazolinona (boa) e sua interação com atrazine no crescimento de plantas
Provedor de dados: Planta Daninha
Autores: Souza,Itamar F.; Einhellig,Frank A.
Dois experimentos de laboratório foram conduzidos na Universidade de South Dakota, Vemillion, SD, EUA, em 1990, para determinar os efeitos do ácido hidroxâmico benzoxazolinona (BOA), do herbicida atrazine e de suas misturas sobre o crescimento e teor de clorofila de lentilha dágua (Lemna minor). BOA na concentração de 0,5 mM foi aplicado em combinação com atrazine a 0,001 e 0,005 mM em caixas plásticas com 24 células de 2,5 ml, contendo 3 frondes de lentilha dágua em solução nutritiva. BOA e atrazine, aplicados isoladamente, inibiram o número, o peso sêco e o teor de clorofila. Atrazine apresentou uma maior ação inibitória que BOA. A combinação BOA (0,05 mM) e atrazine à 0,001 mM foi antagonística. A inibição induzida pelo atrazine a 0,001 mM foi, em...

Interferência das plantas daninhas na cultura do amendoim das águas: efeitos de espaçamentos, variedades e períodos de convivência
Provedor de dados: Planta Daninha
Autores: Martins,Dagoberto; Pitelli,Robinson A.
O presente experimento, conduzido em Jaboticabal, SP, em Latossolo Vermelho Escuro, textura média, teve por objetivo verificar a interferência de plantas daninhas sobre aspectos da produção do amendoim. O delineamento experimental adotado foi o de blocos casualizados, com três repetições, dispostos em esquema fatorial 2x2x8. Constituíram variáveis duas variedades (Tatu e Tatui), dois espaçamentos entre sulcos de semeadura (0,4 e 0,6 m) e oito períodos de controle manual da comunidade infestante (sem controle e com controle até os 10, 20, 30, 40, 50, 60 dias e até o final do ciclo da cultura, a partir da emergência do amendoim).

Injúria potencial de herbicidas de solo ao girassol: III - imazaquin e imazethapyr
Provedor de dados: Planta Daninha
Autores: Fleck,Nilson G.; Vidal,Ribas A.
Conduziu-se um ensaio em campo na Estação Experimental Agronômica da Universidade Federal do Rio Grande do Sul, em Eldorado do Sul, RS, em 1989/90. O objetivo do trabalho foi determinar o efeito residual potencial dos herbicidas imazaquin e imazethapyr, aplicados em três doses à superfície do solo (PRE) ou incorporados no mesmo (PPI), na cultura de girassol. Num sistema de rotação soja-girassol, o efeito residual potencial de imazaquin foi mais acentuado que o de imazethapyr. A atividade herbicida de imazaquin e imazethapyr não foi dependente do método de aplicação. Imazaquin e imazethapyr, nas maiores doses, promoveram danos iniciais acentuados. As plantas de girassol recuperaram-se dos sintomas de intoxicação de imazethapyr, os quais diminuíram com o...

Controle químico da losna em plantio direto de trigo
Provedor de dados: Planta Daninha
Autores: Brighenti,Alexandre M.; Silva,José F. da; Lopes,Nei F.; Cardoso,Antonio A.; Ferreira,Lino R.
A losna (Artemisia verlotorum) é uma planta daninha com alta capacidade de rebrota de seus rizomas e tolerante à maioria dos herbicidas, principalmente os de contato, o que dificulta consideravelmente o seu controle químico e mecânico. Areas naturalmente infestadas com essa planta foram tratadas com glifosate e 2,4-D, em diferentes doses combinadas entre si. O glifosate foi mais eficiente que o 2,4-D. O 2,4-D não apresentou efeito sobre a losna aos 90 dias após sua aplicação. O glifosate apresentou um efeito mais prolongado que o 2,4-D, reduzindo o número de plantas vivas até os 90 dias após sua aplicação. A aplicação das doses intermediárias proporcionou um controle mais eficiente da losna em detrimento do uso de doses mais elevadas. Os valores máximos...

PRICING STRATEGY UNDER MONOPOLY CONDITIONS: AN EXPERIMENT FOR THE CLASSROOM
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Nelson,   Robert G.; Beil,   Richard O., Jr.
This classroom experiment allows students to explore pricing strategies available to the monopolist.  Students are given full information about their costs but know nothing about demand except that it is simulated by the instructor.  They submit their price-asked and quantity-offered records on one day and receive the quantity-sold response from the instructor on the next day, continuing this routine until they discover the profit-maximizing price and quantity.  One of the objectives is to demonstrate that search strategies based on economic principles (MC=MR) can be more efficient than trial-and-error.

TWO-STAGE UTILITY MAXIMIZATION AND IMPORT DEMAND SYSTEMS REVISITED: LIMITATIONS AND AN ALTERNATIVE
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Davis,   George C.; Jensen,   Kimberly L.
Two-stage utility maximization theory has been widely used in the literature to estimate import demand for agricultural commodities that are often inputs. This article examines the overlooked conceptual and empirical limitations of applying two-stage utility maximization theory to model the demand for imported commodities that are inputs. A discussion is presented about how the underutilized theory of two-stage profit maximization overcomes these limitations. Also discussed are the conditions under which errors illustration of the two-stage profit maximization procedure is provided.

A Review of Environmental Valuation in Australia
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Sinden,   Jack A.
Australian attempts to value the environment began at least 40 years ago. Since then, environmental protection and natural resource management have become major national issues. But have the methods of valuation kept pace with the importance of the issues that they are meant to resolve? Can environmental and resource values actually be measured? This paper chronicles, reviews, and assesses the valuations of 40 years and more than 100 Australian authors.

AJAE per capita page counts provide one measure of an institution's research strength.  In this article we refine Willis et al.'s measure of department size and, based on the refined measure, recomputed departmental rankings for North American institutions.  Results indicate that Northeastern United States departments are more widely represented among the top 20 institutions than 20 years ago and that two Canadian institutions-Guelph and British Columbia-rank in the top 12.  The median AJAE publication frequency for the top 30 research institutions is about one article per research faculty member every 12 years.  The AJAE page-count measure was found to be highly correlated (R2 = 0.82) with citation counts, whether narrowly or broadly defined.  Thus, AJAE...

RELEVANCE OF POLICY ANALYSIS: NEEDS FOR DESIGN, IMPLEMENTATION AND PACKAGING
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Skees,   Jerry R.
This article challenges the traditional model of the economist as a humble technocrat who simply provides analysis given the preferences of policy decision-makers.  Since decision-makers rarely reveal their preferences, it is important that the would-be policy research/analyst know the political economy and be willing to identify potential performance goals for society.  Researchers who are willing to incur the transaction cost associated with becoming involved in useful policy research must learn to work within the imperfect policy process.  Policy research that considers the importance of implementation and that acknowledges the institutions and the history will have the highest chance of being useful to policy-makers.

The purpose of this paper is to present some elements of one or more paradigms for assessing a region's economic growth prospects and related infrastructure requirements. These concerns are central to a regional policy that offers guidance for individual decision makers of local governments and their resident populations. A paradigm for regional policy is a model of regional structure and activity that provides a basis for understanding and foresight about regional growth and change. It is a framework for well-targeted infrastructure investments, vigorous and sustained capacity-building, and continuing efforts in intra-regional cooperation.

Wheat Marketing and Trade: Further Issues for Research - a Comment on Ryan
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Ahmadi-Esfahani,   Fredoun Z.
Ryan challenges agricultural economists to help overcome a number of vexed problems facing the Australian wheat industry. Previous attempts to analyse these problems have been inadequate largely because of their inability to integrate real-world market imperfections and dynamics. Accordingly, there may be considerable merit in pursuing an alternative research agenda which employs non-traditional theories, models and estimation methods. Several alternative frameworks including the sunk cost model and strategic trade policy are proposed to address the issues of single desk selling status of the Australian Wheat Board and the US Export Enhancement Program. Additional problems including product differentiation, value adding and liberalisation in importing...

Reforming Water Allocation Policy Through Markets in Tradable Water Rights: Lessons From Chile, Mexico, and California
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Rosegrant,   Mark W.; Gazmuri,   Renato S.
Increasing water scarcity, rising costs of irrigation subsidies, and general economic liberalization are creating strong incentives for comprehensive water reform with establishment of tradable water rights and the development of markets in these rights. Experiences in Chile, Mexico, and California indicate that water allocation through markets in tradable water rights offers a viable approach to improving the efficiency of water allocation, and should receive serious consideration from developing country policy makers. Laws establishing tradable rights should be simple and comprehensive, should clearly define the characteristics of water rights and the conditions and regulations governing the trade of water rights; should establish and implement water...

Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: McLemore,   Donna L.; Keeler,   Andrew G.; Turner,   Steven C.
This study examines the potential success of the futures contract in SO2 Emissions Allowances. Factors affecting the success of the futures contract are presented including the uncertainties of air pollution and public utility regulation, emission control technology, electricity demand, and electric utility needs for an allowance price discovery mechanism for long-range compliance planning under risk. If SO2 futures market is successful, there is some potential for expanding futures trading to other pollutants. Since SO2 is uniquely suited to a national market, duplication of SO2 futures for other pollutants may be difficult.

Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Hillman,   Jimmye S.
It is not likely that Governments will take precipitous action following the Uruguay Round. However, the large industrial economies should continue to press heavily for the revision of farm programs until a better accommodation is reached. The moves toward gradual decoupling of farmers' support payments from agricultural output and price levels should be the first order of business of Governments everywhere. This reform should be supplemented by greater international attention to domestic policies which create non-tariff barriers to trade.

THE ADOPTION OF IPM TECHNIQUES BY VEGETABLE GROWERS IN FLORIDA, MICHIGAN AND TEXAS
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Fernandez-Cornejo,   Jorge; Beach,   E. Douglas; Huang,   Wen-Yuan.
Factors influencing the adoption of Integrated Pest Management (IPM) techniques are studied using survey data from individual vegetable producers from Florida, Michigan, and Texas.  Farmers who adopt IPM tend to be less risk averse and use more managerial time on farm activities than nonadopters.  Adopters are also more likely to operate large, irrigated farms and use more family labor.  Locational factors and the type of crop grown are also influential in IPM adoption.  The analysis uses a logit framework and introduces adopter categories first conceptualized by rural sociologists.

The Uruguay Round trade agreement includes a new programme of work to examine the relationship between trade and environmental policies. Environmental groups remain suspicious that trade liberalisation will undermine or discourage improvements in environmental standards. In this paper, the use of trade measures to protect producers from competition with goods produced under less stringent environmental standards is examined. It is shown that such measures will not improve national welfare, and may undermine environmental policies. Failure of a government to enact appropriate environmental policies constitutes an implicit subsidy, and equity considerations suggest that this will continue to create pressure for changes to the GATT to protect producers who...

FINANCING FARMLAND PRESERVATION: THE TWIN CITIES METROPOLITAN AREA EXPERIENCE
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Greden,   Leah R.; Taff,   Steven J.
Two farmland protection programs in the Twin Cities (Minnesota) Metropolitan Area--Green Acres and Agricultural Preserves-- together enrolled 608,331 acres in 1992.  The principal financing tool was a provision common to both programs under which participating landowners paid reduced property taxes in exchange for certain non- development assurances.  The resulting shift in property tax obligations to other taxpayers amounted to $7.6 million for the 1993 tax year, an average shift of $12.50 per enrolled acre.  Annual per- acre tax reductions across localities ranged from zero to $933.

ENVIRONMENTAL ECONOMIC RESEARCH HAS AN AUDIENCE BUT NOT A SPONSOR: DISCUSSION
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Kealy,   Mary Jo.
There exists no mechanism for federal agencies, national laboratories, industry, and academic institutions to set a national environmental research agenda.  Moreover, funding for social science research is inadequate for providing a sound scientific basis for making environmental policy.  Despite this lack of leadership, it is quite possible to define an environmental economic research agenda that could lead to improved policies for protecting and managing the environment.  The present paper makes some recommendations from an insider's viewpoint.

Resource Economics and the Environment
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Harrison,   Stephen R.; Tisdell,   Clement A.
Recently, a number of specialty areas have developed dealing with the economics of natural systems, resources and the environment. These include natural resource economics, environmental economics, ecological economics and bioeconomics. As well, new government departments, research institutes and tertiary courses have evolved in these areas. This paper examines the evolution and characteristics of the new areas of specialisation, and their relationship with the more traditional discipline of agricultural economics. Environmental economics is viewed as a wider interdisciplinary field than natural resource economics, and ecological economics or bioeconomics is depicted as a branch of natural resource economics dealing with living resources.

INTERREGIONAL EFFECTS OF REDUCED TIMBER HARVESTS: THE IMPACT OF THE NORTHERN SPOTTED OWL LISTING IN RURAL AND URBAN OREGON
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Waters,   Edward C.; Holland,   David W.; Weber,   Bruce A.
A core-periphery, multiregional, input-output model of western Oregon is used to estimate impacts of periphery timber harvest reductions resulting from listing of an endangered species.  Under the most probable scenario, 31,620 total jobs would be lost in the two regions.  Fourteen percent of this impact is absorbed in the core (Metro) region.  Forty percent of periphery and 80% of Metro jobs lost are from service sectors, a result of important core-periphery trade in central place services.  Explicit inclusion of unemployment benefits for displaced workers reduces employment loss estimates by 12% to 14%.

A DYNAMIC ANALYSIS OF THE IMPACT OF WATER QUALITY POLICIES ON IRRIGATION INVESTMENT AND CROP CHOICE DECISIONS
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Wu,   JunJie; Mapp,   Harry P., Jr.; Bernardo,   Daniel J.
A dynamic model is developed to analyze farmers' irrigation investment and crop choice decisions under alternative water quality protection policies.  The model is applied to an empirical example in the Oklahoma High Plains.  The choices of crops and irrigation systems and the resulting levels of irrigation, income, and nitrogen runoff and percolation are simulated over a ten-year period.  An effluent tax on nitrogen runoff and percolation is shown to be effective in reducing nitrate pollution.  The efficacy of cost sharing in adopting modern irrigation technologies and restrictions on irrigation water use depends on soil type.  A tax on nitrogen use is shown to be the least effective policy.

PESTICIDE TAX, CROPPING PATTERNS, AND WATER QUALITY IN SOUTH CENTRAL TEXAS
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Shumway,   C. Richard; Chesser,   Rayanne R.
The impact of an ad valorem pesticide tax on cropping patterns and pesticide use was examined in the South Central Texas Crop Reporting District.  Output supply equations were econometrically estimated and used in the simulation.  A 25 percent tax on pesticide was estimated to have major impacts on cropping patterns and on pesticide use.  Assuming other input and output prices were unaffected, the supply of one important crop would fall by more than half.  Demand for some of the highly soluble and persistent pesticides, which present the greatest threat to groundwater quality, would also decrease substantially (some as much as 50 percent).

We want to clarify the way in which we think about the global commons, particularly the problem of global warming caused by greenhouse gas emissions and tropical deforestation.  We develop a policy framework in which the policy goal is the sustainability of the earth's ability to absorb greenhouse gases.  The framework considers the unequal incidence of benefits and costs of particular policies.  We identify several resource management regimes and suggest that management under a common property regime is most appropriate.  We conclude by identifying and briefly discussing types of policies that can achieve sustainability.

THE ECONOMICS OF CLEANING WINTER WHEAT FOR EXPORT: AN EVALUATION OF PROPOSED FEDERAL "CLEAN GRAIN" STANDARDS
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Adam,   Brian D.; Kenkel,   Philip L.; Anderson,   Kim B.
Buyer complaints about poor quality U.S. wheat have led to proposals to enforce minimum dockage standards for exports.  An economic-engineering approach is used to evaluate costs and benefits of cleaning wheat in order to meet these standards for 13 possible cleaning configurations.  These results are used in an optimization framework to estimate costs and benefits of cleaning all U.S. export wheat.  The estimates indicate that cleaning U.S. export winter wheat to .35% dockage would cost an average of 1 cent/bu., requiring an initial capital investment of $28 million.  Value of wheat lost in cleaning is a significant cost that previously has been overlooked.

THE MEANING OF ROCHDALE: THE ROCHDALE PIONEERS AND THE CO-OPERATIVE PRINCIPLES
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Fairbairn,   Brett.
Rochdale, England, is known by millions for one reason: a handful of labourers established a co-operative there in 1844 known as the Rochdale Society of Equitable Pioneers. That co-operative was adopted as the inspiration and model for a movement that now includes nearly 700 million people around the world.  As this paper is being written, co-operators around the world are preparing to celebrate the 150th anniversary of its birth.  But what did Rochdale mean? Why is it considered so important?

UNDERINVESTMENT AND TIMBER RIGHTS: AN EXAMINATION OF THE EARLY TASMANIAN AND VICTORIAN TIMBER INDUSTRIES
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Pitchford,   R.
This paper distinguishes between the hypothesis that the Victorian government developed a reputation for easy renewal of timber rights, so that the lack of clearly defined site sizes and the short-term nature of these rights did not matter, and the hypothesis that tenure and site size as written in law was the major determinant. A model of a firm's investment choice when there is uncertain tenure is developed to examine the effect of changes in the tenure prospect on capital intensity. The predictions of this model are then used to assess the competing hypotheses with reference to data on capital labour ratios and legislation regarding tenure and site size laws in Victoria and Tasmania from 1890 to 1927.

DEPOSIT-REFUND SYSTEMS: ECONOMIC INCENTIVES FOR THE REDUCTION AND PROPER DISPOSAL OF HAZARDOUS WASTES
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Chu,   Mei-Chin.
Hazardous wastes such as spent solvents and heavy-metal paint waste are characterized by certain adverse properties which include toxicity, reactivity, corrosivity, and flammability. Improper disposal of hazardous wastes may lead to air pollution, water pollution, or soil contamination which are dangerous for human health and for the ecosystem. These effects are known as externalities if the consequences, or costs, are not considered in the waste-generators' decisions. Due to externality, the social costs, including externality costs, and private costs diverge. Since the Love Canal event, hazardous waste disposal (HWD) has drawn national attention. A Roper poll reported that hazardous waste was perceived by the American public as the most important...

The Potential Returns to Oilseeds Research in Uganda: The Case of Groundnuts and Sesame
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Laker-Ojok,   Rita.
The study which follows is an ex-ante analysis of expected returns to investment in agricultural research on groundnuts and sesame in Uganda. Studies have shown that it generally takes a minimum of six to ten years for new technologies to begin to have an impact on agricultural production practices. In the case of Uganda, Michigan State University was asked to measure the impact of a program which only began the process of rehabilitating the collapsed national agricultural research system in 1985 and began support for commodity research on groundnuts and sesame as recently as 1989 and 1991. As a result, the assessment which follows relies upon the projection of expected future benefits. While every effort has been taken to make reasonable projections based...

The cyclical nature of numbers and prices of sheep and lambs was examined from 1924 through 1993.  Tests for structural change also were conducted utilizing the minimization of Akaike's information criterion (MAIC).  Results indicate that cyclical length in both stock sheep numbers and lamb prices has decreased over time, with a current 10- and 27-year cycle in stock sheep numbers and nine- and 27-year cycle lamb prices.  Structural changes occurred in 1951 and 1968 for stock sheep number and in 1952 and 1972 for lamb prices.

Global Competitiveness in the Bottled Water Industry: A Case Study
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Jain,   Subhash C.
The bottled water market in the U.S. is a recent development.  Most water bottlers had traditionally positioned their products as an alternative to tap water.  A few imported waters were sold for health reasons.  The real growth in the bottled water market took place in the second half of 1970s when Perrier was introduced as anon alcoholic, chic alternative to soft drinks and alcoholic beverages.  Bottled water accounted for $3.2 billion sales in 1992 out of a total beverage sales of $159 billion.  Although bottled water is the smallest in terms of revenue, its gallonage market share stood at 8.7 percent, and it is by far the fastest growing category of all beverages.  The future prospects of the bottled water industry in the U.S. appear bright due to the...

A framework was developed in order to specify a model for annual U.S. per capita consumption of cigarettes.  Three separate time related variables were utilized to measure the effects of health related information regarding smoking.  The empirical results from the post World War II data set reveal that while prices and income are important determinants of cigarette consumption, the estimates for both were in the inelastic range.  The age distribution of the adult population is also an important variable.  While the development of the filter tip has been successful in stimulating smoking, the low tar and nicotine innovation has not had a statistically significant effect.  Health information has repeatedly produced substantial short and long run effects....

COST, INPUT AND MARKET SURVEY RESULTS OF THE TEXAS FOOD PROCESSING INDUSTRY
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Wildenthal,   Marie; Capps,   Oral, Jr.; Goodwin,   Harold L., Jr.
State governments are concerned with economic development because the condition of their well being determines residents' standard of living.  Therefore, state governments are interested in strategies for strengthening their economies.  States with substantial agricultural production can implement a strategy of maintaining or increasing markets for that production, positively affecting all of the aforementioned measures.  In some states, the focus has been to "add value" to raw agricultural commodities.  Texas's food processing industry is the focus of this research.  A survey was conducted to determine the cost components of Texas food processors, the percent of purchases from Texas, and reasons for these purchases.  This article summarizes the results of...

Declines in dairy farm numbers and milk production in Minnesota and Wisconsin continue to cause concern to the industry and stimulate activities and proposals to reverse the trend.  But, simply viewing the   aggregate changes in the states' industries overlooks some of the more positive changes in industry structure.  The purpose of this article is to utilize the data that have recently been made available from the 1992 Census of Agriculture to illustrate some divergent trends in dairy farm structure and to make some projections of future industry structure in  these two states.

A Reexamination of the U.S. Export Demand for Soybeans and Soybean Products
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Uri,   Noel D.; Hyberg,   Bengt.
This paper addresses the question of whether the export demand for soybeans and soybean products changed structurally over the 1950 to 1992 period as the U.S. agricultural sector became more integrated with the rest of the world economy. The results suggest that export demands were stable for soybeans, soybean meal and soybean oil over the sample period. Moreover, it is possible to infer conclusively that the long-run soybean and soybean product export price elasticities were in the elastic range. The implications include that for each one percent reduction in the price of soybeans, soybean meal and/or soybean oil brought about through a government program, exports increased by more than one percent, leading to a reduction in the variability of soybean and...

HEDONIC ESTIMATION APPLIED TO THE FARMLAND MARKET IN GEORGIA
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)

Farmland offered for its productive or consumptive value may be viewed as a class of goods characteristic of product differentiation.  Using the generalized Box-Cox transformation, an unrestricted hedonic model was employed to derive implicit valuations of parcel attributes.  Results suggest that the significance and level of importance of attributes on land pricing depends on the spatial extent of markets in Georgia.  Differences in the productive or consumptive use of farmland may imply that different factors and functional forms are appropriate to different farmland markets.

Interstate Differences in the Cost of Complying With Feedlot Environmental Regulations: an Initial Investigation
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Ridley,   Emma J.H.; Morison,   Julian B.; Griffith,   Garry R.
Environmental regulations impose construction and recurring costs on Australian feedlot operators. However to date there has been no published empirical information on these costs of environmental regulation. Additionally, variations in regulations between states and inconsistencies in the application of these regulations may have resulted in a pattern of location different from that dictated by least cost grain and feeder cattle inputs and processing and transportation services. The aim of this study was to attempt to measure the cost of complying with environmental regulations by large commercial feedlots in different Australian states. From data provided from a survey of 20 commercial feedlots it was found that the average cost of complying with these...

ECONOMICS OF TRADE-OFF BETWEEN UREA NITROGEN AND POULTRY LITTER FOR RICE PRODUCTION
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Govindasamy,   Ramu; Cochran,   Mark J.; Miller,   David M.; Norman,   Richard J.
This paper identifies optimal combinations of nitrogen in the form of urea, fresh litter and composted litter for rice production.  Traditional cost minimization techniques using data from experimental results conducted at three sites in Arkansas during 1991 have been employed.  Comparisons between different scenarios indicate that the trade-off between the use of poultry litter and urea nitrogen depends on such factors as soil fertility, the yield response to litter application and the relative prices of nitrogen and litter.  The use of litter is more economical at high target yields than at low target yields.

GROWTH IN AGRICULTURAL LOAN MARKET SHARE FOR ARKANSAS COMMERCIAL BANKS
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Ahrendsen,   Bruce L.; Dixon,   Bruce L.; Priyanti,   Atien.
Changes in commercial bank market shares of farm debt are decomposed into portfolio decisions loanable funds availability and loan market size for 64 counties in Arkansas from 1986 through 1990.  A seemingly unrelated regression model is hypothesized to identify county characteristics that are related to changes in commercial bank market shares.  Regression results indicate that county differences in economic activity, the relative risk associated with agriculture, farm structure and regional location contributed to changes in commercial bank market shares.  The results imply a market niche for rural commercial banks emphasizing agricultural loans in the presence of unlimited branch banking.

Autores: Betubiza,   Eustacius N.; Leatham,   David J.
A discrete stochastic, programming model is formulated to study the gains from diversification when farming operations are augmented with off-farm financial assets that are not highly correlated with returns from farming.  We extend past research by considering the dynamics of accumulating these financial assets and the farm's leverage and tenure position.  Results show that farmers' income level and stability can be improved by including nonfarm financial assets in their portfolios.

REFLECTIONS ON RELEVANCE OF PROFESSIONAL JOURNALS
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Robison,   Lindon J.; Colyer,   Dale.
It appears the major private benefit from peer reviewed journals such as the Review of Agricultural Economics (RAE) is certification.  To maintain public support for our journals, increased efforts are needed to demonstrate the social benefits from peer reviewed publications.  Research cost considerations have led agricultural economists to emphasize applied disciplinary work using secondary data and to ignore the important work of careful data collection and reporting.  Moreover, pressures to publish have led to more isolated research efforts ignoring other disciplines.  Recommendations to improve the relevance of journal publications include more active efforts by journal editors to make applied journals such as RAE more accessible to the public.

Autores: Garcia,   Philip; Adam,   Brian D.; Hauser,   Robert J.
This study provides additional evidence of the usefulness of mean-variance procedures in the presence of options which can truncate and skew the returns distribution.  Using a simulation analysis, price hedging decisions are examined for hog producers when options are available.  Mean-variance results are contrasted with optimal decisions based on negative exponential and Cox-Rubinstein utility functions over 56 ending price scenarios and two levels of risk aversion.  The findings from our simulation, which considers discrete contracts, basis risk, lognormality in prices, transactions costs, and alternative utility specifications, affirm the usefulness of mean-variance framework.

Population projections depend on censuses, vital statistics, and sample surveys, all of which have deficiencies that are most marked in developing countries.  Long-range projections by international agencies have recently undergone major revisions, and forecasts of the United States (U.S.) population have changed drastically over the past four years.  The United Nations (UN) typically prepares high, medium, and low projections.  Even the high projection contains optimistic assumptions about fertility decline, while assumptions of constant or increasing fertility receive no serious attention.  This paper suggests that high and constant fertility projections should receive more attention from policymakers. They should treat medium estimates as targets...

NUTRITION INFORMATION AND HOUSEHOLD DIETARY FAT INTAKE
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Gould,   Brian W.; Lin,   Huei Chin.
An endogenous switching regression model is used to examine how meal planner health knowledge affects dietary fat intake. Ethnicity, income, meal planner age, being on a low-fat diet, and other health awareness behaviors had significant effects on health knowledge. After controlling for differences in household and meal planner characteristics, intake of total and saturated fat was found to depend on health knowledge status.

Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Stycos,   J. Mayone.
Although recent academic and popular attention has argued for a wedding between population and environmental problems and policies, the scientific knowledge base for these topics has grown separately and at different rates.  Environmental research has grown faster than population research, while the joint treatment of these topics remains in its infancy.  International polls that have included many questions concerning environmental attitudes have included far fewer on population.  The few surveys on population attitudes have ignored the environment.  The World Fertility Survey and the Demographic and Health Survey are fertility, rather than population, surveys.  They have been useful in precipitating national policies on family planning but are poor...

Market Power and the Demsetz Quality Critique: An Evaluation for Food Retailing
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Cotterill,   Ronald W.; Harper,   C. David.
This study analyzes supermarket firm prices to determine whether prices are related to market structure and whether the Demsetz quality critique is valid.  Factor analysis is used to identify five service factors that are modeled with price as endogenous variables in a simultaneous equations framework to test whether a more concentrated market structure is related to higher service levels which, in turn, are related to higher prices (the Demsetz hypothesis) and whether a more concentrated market structure is directly related to higher price (market power hypothesis).  For this study of supermarkets in 34 local markets in six southwestern states, market share and concentration are not significantly related to any service factors.  Concentration has a...

A Survey of Noncooperative Game Theory with Reference to Agricultural Markets: Part 2. Potential Applications in Agriculture
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Sexton,   Richard J.
This paper is the second of a two-part survey on noncooperative game theory relevant to agricultural markets. Part 1 of the survey focused on important game theory concepts, while this paper illustrates applications of the theory to agricultural markets. Game theory is relevant when markets are imperfectly competitive, and this paper argues that this condition is commonly met in agriculture. Specific topics of application include principal-agent models, auctions, and bargaining.

THE NATIONAL INTEREST, WESTMINSTER, AND PUBLIC CHOICE
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Johnson,   R.W.M.
There has been increasing scrutiny of government policy decisions and advice in recent years. The supremacy of the national interest has been questioned and self interest theories explored. Administrative systems have been reformed, and the role of the Westminster model of government decision-making endlessly reviewed. Increased interest by economists in the policy process has created a new subject area in economics, namely, public choice theory. It places greater emphasis on individual choice and hence on the way political institutions meet society's needs. It provides a suitable framework for explaining political decision making and administrative processes. In this Address, New Zealand agricultural policies and processes in the last two decades are...

Global Competitiveness in the Beer Industry: A Case Study
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Jain,   Subhash C.
Three companies (Anheuser-Busch, Miller, and Coors) in the brewing industry accounted for 78 percent of the U.S. market in 1992.  Among these three, Anheuser-Busch is the apparent leader with 46.2 percent of the market.  Although Anheuser-Busch produces and markets a number of brands, the Budweiser brand has been the top selling beer with 24.1 percent market share in 1992.  Lately, light beers have been gaining ground, a trend likely to continue in the future.  Foreign beer brands account for about eight percent of the U.S. market.  The foreign brands are popular in certain niches of the market.  While the imported brands are likely to remain popular, they are no threat to the domestic competitors.  A new trend in the market is the emergence of the...

THE EFFECTS OF INCREASING FLEX ACRES ON FARM PLANNING AND PROFITABILITY
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Duffy,   Patricia A.; Taylor,   C. Robert.
Dynamic programming techniques were used to evaluate the effects of alternative levels of normal flex acreage requirements on a Midwestern corn-soybean farm and a Southeastern cotton farm.  Results indicate that increasing normal flex acres from the current level of 15 percent to 35 percent would provide inducement for farmers in both regions to plant more soybeans.  In general, the cotton farm incurs considerably higher expected losses from the change.  Thus, there are unequal regional consequences of such a policy change.

Financial Appraisal of the Banks for Cooperatives
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Weldon,   Richard N.; Srinarni,   Endah; Moss,   Charles B.; VanSickle,   John J.
This study examines the financial situation of the Farm Credit System Banks for Cooperatives using comparative analysis for the period 1978 through 1991. Profitability and leverage measures of the Banks for Cooperatives are compared with similar measures of large commercial banks. The Banks for Cooperatives were found to have performed as well as large commercial banks. Some differences can be explained as compatible with differences in the goals and objectives of a cooperative versus an investor-owned firm. Most differences can be attributed to the financial strength of the Banks for Cooperatives relative to the commercial banking industry.

PREMIUM RATE DETERMINATION IN THE FEDERAL CROP INSURANCE PROGRAM: WHAT DO AVERAGES HAVE TO SAY ABOUT RISK?
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Goodwin,   Barry K.
This article reviews actuarial procedures used to calculate premium rates in the federal crop insurance program. Average yields are used as an important indicator of risk under current rating practices. The strength and validity of this relationship is examined using historical yield data drawn from a large sample of Kansas farms. The results indicate that assumed relationships between average yields and yield variation are tenuous and imply that rating procedures that rely on average yields may induce adverse selection.

Interactions Between Food Market Reform and Regional Trade in Zimbabwe and South Africa: Implications for Food Security
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Jayne,   Thomas S.; Takavarasha,   T.; van Zyl,   Johan.
A major role of agricultural policy is to identify policy changes that may induce technological innovation and productivity growth throughout the food system, in order to increase the living standards of people who must relate to it in one way or another. While food market reform has been subject to contentious and often emotional debate over the last decade in Africa, the debate has generally been over assumptions about how food markets work in reality as opposed to theory, and how markets actually respond to particular forms of policy change. The lack of consensus is partially due to a shortage of empirical, ground-level information linking specific policies to specific impacts. It is in this context that we draw on applied analysis in Southern Africa to...

CONSUMER PREFERENCE FOR PST-SUPPLEMENT PORK
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Halbrendt,   Catherine K.; Pesek,   John D., Jr.; Parsons,   April; Lindner,   Robert K.
Conjoint measurement was used to determine consumer preference for fresh pork produced with genetically engineered porcine somatotropin (pST). A preference model was constructed based on three pork attributes, degree of fat reduction, price, and production technology, which allowed for interactions between attributes to be estimated. Interview surveys were used to collect data in several shopping centres in three Australian cities. Respondents generally preferred leaner pST-supplemented pork, but only at fat reduction levels greater than those possible with conventionally produced pork, and at competitive prices.

PRICE-BAND STABILIZATION PROGRAMS AND RISK: AN APPLICATION TO THE U.S. CORN MARKET
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Holt,   Matthew T.
The impacts of introducing a partial price stabilization scheme in the U.S. corn market are investigated by using a modified version of the bounded price variation model.  Specifically, a model is developed and estimated that includes rational expectations of the first three central moments of the (truncated) equilibrium price distribution.  The estimated model is used to stimulate market equilibrium effects of introducing upper and lower price limits through a tax-subsidy scheme.  The results show that corn producers are downside risk averse, and that market feedback effects of price stabilization can, at times, be more important than direct effects.

Autores: Kaiser,   Harry M.
This paper investigates the impacts of alternative federal dairy policies on the U.S. dairy sector.  In addition to the current dairy price support program, five alternatives are investigated: (1) immediate deregulation, (2) gradual deregulation, (3) target price-deficiency payment program without supply control, (4) target price-deficiency payment program with supply control, and (5) mandatory supply control.  An econometric model of the national dairy industry is used to simulate quarterly equilibrium price and quantity values at the farm and wholesale levels for each policy over the period 1980-90.  Consumers are better off under both immediate and gradual deregulation, as well as the target price-deficiency payment scenarios because prices are lower,...

DEVELOPING FLEXIBLE ECONOMIC THRESHOLDS FOR PEST MANAGEMENT USING DYNAMIC PROGRAMMING

Autores: Harper,   Jayson K.; Mjelde,   James W.; Rister,   M. Edward; Way,   Michael O.; Drees,   Bastiaan M.
The rice stink bug is a major pest of rice in Texas, causing quality related damage.  The previous threshold used for assisting in rice stink bug spray decisions lacked flexibility in economic and production decision variables and neglected the dynamics of the pest population.  Using stochastic dynamic programming, flexible economic thresholds for the rice stink bug were generated.  The new thresholds offer several advantages over the old, static thresholds, including increased net returns, incorporation of pest dynamics, user flexibility, ease of implementation, and a systematic process for updating.

Concentration-Price Relations in Regional Fed Cattle Markets
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Marion,   Bruce W.; Geithman,   Frederick E.
Since 1977, the U.S. beef packing industry has been restructured at a pace unprecedented in large American industries.  By 1987, four packers slaughtered over two-thirds of all steers and heifers.  In the thirteen regional feedlot-packer markets studied here, the four leading packers slaughtered 85 percent of fed cattle, on average.  The impact of packer concentration on fed cattle prices during 1971-86 was examined using several econometric models.  The results generally support the hypothesis that packer concentration was negatively related to live cattle prices.  Cattle prices were estimated to be about 3 percent less in the most concentrated region compared to the least concentrated region.  There was evidence of a critical concentration of CR4 = 60 in...

AN EXPERIMENT IN CONTINGENT VALUATION AND SOCIAL DESIRABILITY
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Laughland,   Andrew S.; Musser,   Wesley N.; Musser,   Lynn M.
Social desirability (SD) represents the problem of subjects responding with social norms rather than individual values.  This paper briefly surveys the SD literature and considers its relevance for contingent valuation (CV) studies.  In an empirical study, undergraduate students were administered the Marlowe-Crowne Social Desirability Scale, as well as CV questions.  High SD scores were hypothesized to imply a greater likelihood of offering a protest reason for a zero bid and to increase bids for socially desirable commodities.  While all hypotheses were not supported, the empirical results suggest that SD can influence CV responses and should not be dismissed prematurely.

IDENTIFYING A REDUCED SET OF SALIENT ATTRIBUTES THAT INFLUENCE CONSUMERS' CHOICE AMONG WHOLE, LOW-FAT, AND SKIM MILK FOR BEVERAGE USE
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Miles,   Heiko; Schwager,   Steven J.; Lenz,   John E.
Fishbein's Theory of Reasoned Action models behavior as based on beliefs and evaluations on a small set of salient attributes. Two methods of reducing large sets of potentially salient attributes into a smaller set of salient attributes are proposed. The methods are based on expectancy valuation analysis and logistic regression analysis. When applied to consumer beliefs and evaluations on 59 attributes over three milk types (whole, low-fat, and skim milk), both methods identify reduced sets of attributes. The reduced attribute sets are then used to model whether or not respondents drink a particular milk type. Results indicate that the reduced models are statistically significant in explaining choice of m"ilk type although there is some loss of information...

YIELD RESPONSE AND PRODUCTION RISK: AN ANALYSIS OF INTEGRATED PEST MANAGEMENT IN COTTON
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Hurd,   Brian H.
Production uncertainty is commonly believed to be an impediment to the adoption of less pesticide-intensive methods in agriculture such as integrated pest management (IPM).  To investigate the effects of pest control inputs on yields and yield variability, data from a cross-section of San Joaquin Valley cotton producers were analyzed in a heteroskedastic production model.  The results suggest that yields are increasing with soil quality, crop rotation, frequency of field monitoring, and the use of independent pest control advisors.  Yield variability was not found to be significantly affected by production inputs, including pesticides and IPM practices with the exception of frequent contact with extension farm advisors which was found to contribute to...

PROJECTED CONSUMPTION OF LIVESTOCK PRODUCTS
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Grande,   Jorunn; Houck,   James P.; Olson,   Kent D.
The U.S. consumption pattern of livestock products has changed considerably and is expected to keep changing. The first part of this paper reviews the consumption trends and the price and nonprice factors affecting those trends. In the second part, future consumption patterns are projected. The projections of the constant income elasticity model and the Tornquist functions are rejected due to recent trends which do not receive enough weight in these models. A third model which projects consumption shares is selected as a more accurate predictor. By the year 2010, national consumption of beef is estimated to decrease by 5 to 10%; pork to increase by up to 5%. Lamb and mutton will continue to be consumed less. Poultry consumption will increase dramatically...

This summary and analysis of 343 New York dairy farm businesses demonstrates the use of cash accounting and accrual adjustments to measure farm profitability, cash flow, financial performance, and costs of producing milk. Traditional methods of analyzing dairy farm businesses are combined with improved evaluation techniques to show the relationship between good management performance and financial success. These farms averaged 130 cows per farm and 18,858 pounds of milk sold per cow in 1993, which are above the average size and management level of all New York dairy farms. Net farm income excluding appreciation, which is the return to the operator's labor, management, capital, and other unpaid family labor, averaged $43,936 per farm. The rate of return...

COORDINATING PRODUCTION AND DISPOSAL OF COMMODITY STOCKPILES WITH APPLICATION TO AUSTRALIA'S WOOL INDUSTRY
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Hertzler,   Greg.
Following the dismantling of a price-support program, a central bureaucracy is left with a commodity stockpile to dispose. It happened with wheat and feed grains in the U.S. in 1986 and wool in Australia in 1991. It soon may happen in Europe with grains, manufactured dairy products and other commodities which have supported prices. Obvious policies include privatising the stockpile, disposing of the stockpile by a central bureaucracy and quarantining the stockpile from the market. Each policy imposes constraints on disposal based, perhaps, on judgments of political acceptability to producers and government. In this article, optimal rules for production and disposal are derived and solved and a new policy is proposed. Then the model is applied to the...

THE EFFECT OF QUALITY ASSURANCE POLICIES FOR PROCESSING TOMATOES ON THE DEMAND FOR PESTICIDES
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Starbird,   S. Andrew.
In California, acceptance sampling is used to monitor the quality of processing tomatoes delivered by growers to processors.  A proposal to change the current quality assurance policy was recently put forth to reduce the growers’' incentive to use pesticides.  In this article we examine the effect of alternative quality assurance policies on profit-maximizing grower’s' demand for pesticides.  The results indicate that the demand for pesticides is sensitive to changes in the quality assurance policy and that the proposed policy would reduce the optimal level of pesticide use on processing tomatoes.  Disregarding the impacts of quality assurance policy may be the reason that the demand for pesticides has been underestimated so often in the past.

Sesgos en la medición de la inflación en contextos inflacionarios: el caso peruano
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Escobal D'Angelo,   Javier; Castillo,   Marco.
La posible sobrevaluación del Indice de Precios al Consumidor de Lima Metropolitana ha sido un problema que ha venido preocupando tanto a académicos como a tomadores de decisiones y a la opinión pública en general desde hace ya algún tiempo.  Muchos desconocen que la sobreestimación del Producto Bruto Interno per cápita y del retraso cambiario, o la subestimación de la presión tributaria, tiene su origen en el mismo problema de medición del IPC. Sin embargo, la existencia de dichos sesgos es reconocida cada vez más como asuntos que necesitan ser urgentemente abordados y solucionados.  Entender la naturaleza exacta de estos problemas es indispensable si se pretende corregirlos adecuadamente. Este documento parte de la teoría de los índices del costo de vida...

HABIT FORMATION AND VARIETY SEEKING IN A DISCRETE CHOICE MODEL OF RECREATION DEMAND
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Adamowicz,   Wiktor L.
The recreational site choice decision modeled in most economic analyses seldom contains previous experience with the site as a characteristic or attribute.  A rational dynamic model is used to incorporate previous experience with the site in a model of the choice of recreation sites.  Based on the comparison of dynamic and static models, it is apparent that dynamic elements influence choice.  The use of previous consumption as an attribute (either in a naïve or rational form) is an improvement over static models of choice.  In welfare analysis, this effect may be a significant factor.  For example, a change in prices or quality attributes may have a much larger impact on those individuals who have developed habits.

TASTE CHANGES IN THE DEMAND FOR FOOD BY DEMOGRAPHIC GROUPS IN THE UNITED STATES: A NONPARAMETRIC EMPIRICAL ANALYSIS
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Cortez,   Rafael; Senauer,   Benjamin.
This study uses nonparametric techniques to analyze the stability of demand for 19 major food categories among various demographic groups in the United States. Households are divided into population groups by income, the head's age, and the spouse's education level. The data used are from the 1980-1990 Dairy portion of the Bureau of Labor Statistics annual Consumer Expenditures Surveys. The programming model developed by Sakong and Hayes is used to test for and measure taste changes. Substantial differences in preference trends between population groups are found for many of the food commodities.

THE ROLE OF SMALL RICE MILLS IN THE RICE SUBSECTOR OF THE OFFICE DU NIGER, MALI
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Diarra,   Salifou Bakary.
The presence of the small rice mills in the Office du Niger zone has changed the structure of the rice subsector, helping to reduce concentration and changing marketing options of both farmers and retailers. Current proposals call for major initiative to liberalize the rice market further and to shift the principal role of the O.N. toward provision of water and extension. In this context, it is extremely important to investigate the role of small mills in the subsector, their relative costs, and the segments of the market they serve.  Budgeting techniques were used to analyze milling cost data. Price data were used to calculate both correlation coefficients and spatial marketing margins. The analyses of correlation and calculation of spatial margins...

POPULAR PARTICIPATION IN THE MANAGEMENT OF NATURAL RESOURCES: LESSONS FROM BABAN RAFI, NIGER
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Elbow,   Kent M.
This paper is divided into six chapters. The first introduces the central issue under investigation: the hypothesized relation between devolution of authority over natural resources and the sustainable exploitation of those resources. This chapter also provides a discussion of the research methodology employed in the course of the investigation. Chapters 2 and 3 constitute a unit compiling a broad composite of social and (to a lesser degree) physical traits relevant to locally prevailing resource exploitation practices and patterns. Thus chapter 2 consists of a detailed physical and social profile of the site of Baban Rafi, while chapter 3 focuses on past and present resource use and tenure systems. Chapters 4 and 5 address the broad institutional issues...

PRODUCTION STRUCTURE AND THE AUSTRALIAN SAWMILLING INDUSTRY
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Bigsby,   Hugh R.
This paper examines the production structure of the Australian sawmilling sector over the period 1950-51 to 1984-85 using a translog cost function. The results show that the sawmilling industry is best represented by a production function which does not have any restrictions on functional form. Inputs, including capital, labour, materials and energy, are generally found to substitutable for one another, although the degree of substitutability is small. There have been economies of scale in the Australian sawmilling industry, and technological change has been capital and energy-using, and labour and materials-saving.

Assessing the Impact of Cowpea and Sorghum Research and Extension in Northern Cameroon
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Sterns,   James A.; Bernsten,   Richard H.
Throughout Africa, per capita food production has been declining since the early 1960s. Cameroon has sought to counter this trend by increasing agricultural productivity through research and extension. In order to establish future investment priorities, policy makers need to know if past agricultural research investments have earned sufficient returns to justify continued funding. Further, national experiences need to be compared to see if returns varied across programs, and in cases where they did, explanations need to be sought to discover why these variations exist. To address these issues, data were collected in Cameroon and analyzed in order to estimate the benefits and costs of investments in sorghum and cowpea research and extension in northern...

RISK PREFERENCES AND CONTRACTING IN THE U.S. HOG INDUSTRY
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Johnson,   C. Scott; Foster,   Kenneth A.
Much of the increase use of vertical coordination in the U.S. swine industry has taken place through contract production.  While the incidence of contracting is much higher in nontraditional hog production areas, a growing number of Midwestern producers are being faced with contract options.  A variety of contractual arrangements are available through feed companies, integrators, genetics firms, and packers.  However, little is known about the profitability and risk characteristics of these alternatives.  This research suggests that risk neutral producers in the Midwest would prefer independent production, and risk averse producers would prefer to choose among the various types of coordination arrangements.

Endangered Species and Natural Resource Exploitation: Extinction vs. Coexistence
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Tsur,   Yacov; Zemel,   Amos.
The threat on the survival of animal species due to intensive use of natural resources is incorporated within resource management models, paying special attention to uncertainty regarding the conditions that lead to extinction. The manner in which the potential benefits forgone due to the species extinction (denoted extinction penalty) induce more conservative exploitation policies is studied in detail. When the extinction penalty is ignored, the optimal policy is to drive the resource stock to a particular equilibrium level from any initial state. When the extinction penalty is considered and the conditions that lead to extinction are not fully understood (i.e., involve uncertainty), an interval of equilibrium states is identified, which depends on the...

THE ECONOMICS OF GRAIN PRODUCER CARTELS
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Gleckler,   James; Tweeten,   Luther G.
The objective of this study is to measure economic payoffs from a grain cartel. Two basic approaches to extract economic rents are considered: (i) Mandatory supply controls to restrict production and raise grain price, and (2) export price discrimination using export taxes or subsidies. The economic impacts of different producer cartel scenarios were estimated using a long-term, nine-region world trade simulation model incorporating the assumptions of neoclassical trade theory. The SWOPSIM program was used to write the model equations. Economic Research Service trade data for 1989 were used to initialize the model. Results reflect long-run changes from 1989conditions and are at 1989 general price levels. The model simultaneously estimated outcomes in...

AGROENVIRONMENTAL ECONOMIC RESEARCH FOR THE 21ST CENTURY: ANITICIPATING AND RESPONDING TO CHANGE
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Smith,   Katherine R.
It is proposed that "real" research issues are socially relevant, provide findings with utility beyond the profession, and are anticipatory.  An industrializing agricultural sector, an evolving political economy of agroenvironmental policy, an increasingly transnational economy, and rapid population growth are important sources of change to which research on real agroenvironmental issues must respond.  Specific, identified "real" research issue areas include: benefit-risk assessment methodology; agroenvironmental regulation for industrialized agriculture; trade agreements and environmental quality; the recreation-tourism-agriculture interface; sustainable development; and the formation of preferences.  The nature of identified issues suggests more...

Improving Horticultural Export Performance of Developing Countries in Asia
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Jansen,   Hans G.P.
Many developing countries in Asia have a comparative advantage in the production of horticultural commodities with favourable growth prospects in world markets due to relatively high income and price elasticities. As a result, the horticultural sector has traditionally been an important source of foreign exchange earnings in Taiwan, China, the Philippines and (more recently) Thailand and Malaysia. On the other hand, the performance of potentially significant exporters in South Asia has been disappointing. Drawing from the widely diverging experiences of six countries, it is concluded that government policies significantly influence horticultural export performance. To meet strict consumers' specifications in importing countries, maximum cooperation is...

RETHINKING CONTRACTS FOR PURCHASING POWER: THE ECONOMIC ADVANTAGES OF DISPATCHABILITY
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Dorris,   Gary W.; Mount,   Timothy D.
The purpose of this article is to evaluate and compare the incremental cost of purchased power from non-utility generators versus utility built generation considering a variety of contracts for energy purchases. Four types of contracts are evaluated: I) Flat Rate Produce and Pay, 2) On-Peak/Off-Peak, 3) Basic Dispatchable, and 4) Actual Cycle Energy Dispatch. The type of contract can affect the competitiveness of electric rates through increased energy production costs as well as increased risks, in terms of financial liability, affecting the cost of debt to the purchasing utility. An analysis conducted for a representative utility calculates the effects of NUG power purchases on a utility's energy production costs and the cost of new debt issuances....

ECONOMIES OF THROUGHPUT AND TRANSPORT BOTTLENECKS IN GRAIN DISTRIBUTION SYSTEMS
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Brennan,   Donna C.
In this paper, a model is presented which shows the relationship between country grain storage costs and transport bottlenecks that exist in the harvest period. It is shown that transport bottlenecks limit the amount of grain that can be transported from receival points in the peak receival period. This constraint means that the cost of operating country receival points is high because the turnover of storage capacity is limited. However, system costs can be reduced by focusing the peak transport task at sites that are less intensive users of scare transport capacity. This allows more grain to be transported out of the system in the peak period, decreasing the need for costly long term storage at country sites.  In the longer term, differences in the...

THE INVERSE LEWBEL DEMAND SYSTEM
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Eales,   James S.
A new model of consumer preferences is introduced.  It is appropriate for modeling perishable commodities which are produced with a lag, where it is reasonable to assume the market-level quantities are fixed by previously made production decisions.  The inverse Lewbel system, as it is called, is a flexible nonlinear system of share equations, which nests two other inverse demand systems, the direct translog and the inverse AIDS.  Thus, the inverse Lewbel may be employed to test whether these more restrictive preference structures are appropriate.  In an application to quarterly U.S. meat consumption, the more restrictive structures are rejected.

KANSAS WHEAT YIELD RISK MEASURES AND AGGREGATION: A META- ANALYSIS APPROACH
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Marra,   Michele C.; Schurle,   Bryan W.
A meta-analysis approach to prediction of farm level yield risk from county level yield series is applied to Kansas wheat yields.  A nonlinear relationship between county level and farm level yield risk is found, which indicates that yield risk increases at an increasing rate as the number of acres in the risk measure decreases.  County level yield variability should be adjusted upward by approximately .1% for each percent difference in county acreage and average farm acreage within the county.  The meta-analysis approach is shown to be promising for the prediction of farm level yield risk when farm level information is difficult to obtain.

ECONOMETRIC PRODUCTION MODELS WITH ENDOGENOUS INPUT TIMING: AN APPLICATION TO ECUADORIAN POTATO PRODUCTION
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Antle,   John M.; Capalbo,   Susan Marie; Crissman,   Charles C.
In this article, a model was developed in which the quantity and timing of input and harvest decisions are endogenous.  The endogenous timing model allows all of the information about input and harvest behavior to be utilized, and it provides a basis for linking econometric production analysis to the time-specific analyses in other scientific disciplines used to assess the environmental or human health impacts of agricultural production practices. The case study of fungicide use on Ecuadorian potatoes was conducted with a unique data set containing detailed information on both quantity and timing of input use.  The results showed that both quantity and timing of chemical use were responsive to economic variables.

CATTLE FEEDER BEHAVIOR AND FEEDER CATTLE PLACEMENTS
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Kastens,   Terry L.; Schroeder,   Ted C.
Cattle feeders appear irrational when they place cattle on feed when projected profit is negative. Long futures positions appear to offer superior returns to cattle feeding investment. Cattle feeder behavior suggests that they believe a downward bias in live cattle futures persists and that cattle feeders use different expectations than the live cattle futures market price when making placement decisions. This study examines feeder cattle placement determinants, comparing performance of expected hedgeable profit with past actual profit in explaining feeder cattle placements. Past actual profit is a more important placement determinant than expected profit based upon the live cattle futures market, even though hedgeable profit provides a superior forecast...

NONFARM EMPLOYMENT IN SMALL-SCALE FOREST-BASED ENTERPRISES: POLICY AND ENVIRONMENTAL ISSUES
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Arnold,   John Edward Michael.
Employment and income from non-farm activities are of increasing importance in the rural economy of developing countries.  Small forest-based enterprise activities constitute one of the largest sources of such income.  They also account for a large part of the total harvest from forests in many areas. Many agriculturalists supplement their income through gathering and trading products such as forest foods, medicinal plants, and fuel wood.  Small-scale manufacturing of items such as furniture, baskets, mats, and craft goods constitute substantial informal sector industries.  Income from these activities tends to be particularly important during seasonal shortfalls in food and cash crop income and in periods of drought or other emergencies. Ease of access to...

Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Thayer,   Sharon; Zulauf,   Carl R.; Schnitkey,   Gary D.; Forster,   D. Lynn.
Crop yields which determine farm income deficiency payments have been frozen at 1981-1985 levels since 1986.  Data from a longitudinal survey of Ohio farm operators are analyzed to evaluate whether updating payment yields will differentially affect farm operators.  Results of the analysis imply that farm operators who operate larger farms, live in counties with higher yields, and have higher fertilizer and pesticide expenses per acre of corn will benefit more.  In addition, low (high) existing payment yields are understated (overstated) relative to updated payment yields.

AN OPTIMAL MANAGEMENT MODEL FOR INTENSIVE AQUACULTURE - AN APPLICATION IN ATLANTIC SALMON
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Hean,   Robyn L.
In this paper the optimal management strategy for intensive aquaculture is viewed in terms of a combined strategy of releasing the optimal number of recruits and harvesting those recruits at the optimal harvesting time. A model which can be used to determine the optimal management strategy is developed. In the model the optimal harvesting model documented by Bjorndahl (1988, 1990) in which harvesting and feed costs are considered, is extended by including release costs and how they influence the optimal number of recruits. The model forms the basis for an empirical analysis in which the optimal management strategy for a yearclass of Atlantic salmon farmed in Australia during 1989-91 is considered.

EFFECTS OF SOCIOECONOMIC AND DEMOGRAPHIC FACTORS ON CONSUMPTION OF SELECTED FOOD NUTRIENTS
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Nayga,   Rodolfo M., Jr.
The effects of socioeconomic and demographic factors on the consumption of food energy, protein, vitamin A, vitamin C, thiamin, riboflavin, niacin, calcium, phosphorus, and iron are examined.  Socioeconomic and demographic factors analyzed are urbanization, region, race, ethnicity, sex, employment status, food stamp participation, household size, weight, height, age, and income.  Several of these factors significantly affect consumption of certain nutrients.  Income is an important factor affecting the consumption of vitamin A, vitamin C, and calcium.  Income elasticities are relatively small at low income levels.  For example, income elasticities range from 0.016 for calcium to 0.123 for vitamin C at an income level of $20,000.

ARE LOWER-INCOME SHOPPERS AS PRICE SENSITIVE AS HIGHER-INCOME ONES?: A LOOK AT BREAKFAST CEREALS
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Jones,   Eugene; Chern,   Wen S.; Mustiful,   Barry K.
Scanner data for breakfast cereals are used to estimate demand elasticities for six supermarket stores in two distinct socio-economic areas.  Three stores are in low-income locations and three are in high-income locations.  A time series cross-section model is estimated for five product categories across six cross sections over forty-two weeks.  Results show lower-income shoppers to have more elastic demands for four of the five product categories: private label cold cereals, the top ten brands of cold cereals, all other brands of cold cereals, and hot cereals.  Price is not statistically significant for a fifth product category, snack cereals.

MARKET SEGMENTATION: IDENTIFYING THE HIGH-GROWTH EXPORT MARKETS FOR U.S. AGRICULTURE
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Reed,   Michael R.; Salvacruz,   Joseph C.
A cluster analysis based on a five-year growth rate of agricultural imports from the United States was conducted on 86 countries and revealed two significant market segments for U.S. agriculture: the high-growth markets and the low-growth markets.  Multiple discriminant analysis was then used to test the significance of the countries' trade-related and macroeconomic variables to their market growth classification.  The discriminant function was used to predict the high-growth markets for U.S. agriculture in 1994.  High-growth markets for U.S. agriculture exhibit faster GDP and agricultural import growth rates, are relatively agriculturally self-sufficient, and are near the United States.  On the other hand, low-growth markets exhibit slower GDP and...

NONCOMPETITIVE PRICING AND EXCHANGE RATE PASS-THROUGH IN SELECTED U.S. AND THAI RICE MARKETS
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Yumkella,   Kandeh K.; Unnevehr,   Laurian J.; Garcia,   Philip.
A "pricing to market" international trade model is applied to U.S. and Thai rice exports to high and middle income countries that are continuous rice importers.  These markets are characterized by strong quality preferences and highly inelastic demand, and thus exporters may exercise market power.  Evidence of noncompetitive pricing either through price discrimination across destinations or through imperfect exchange rate pass-through is found in this small but growing segment of the international rice trade.

Understanding Linkages among Food Availability, Access, Consumption, and Nutrition in Africa: Empirical Findings and Issues from the Literature
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Diskin,   Patrick K.
This paper starts with the unsurprising observations that (1) having enough food available at national and local levels is necessary but not sufficient for ensuring that households have adequate access to food; (2) having adequate household access to food is necessary but not sufficient for ensuring that all household members consume an adequate diet; and (3) consuming an adequate diet is necessary but not sufficient for maintaining a healthy nutritional status. Recognizing that the links from food availability to access to consumption to nutritional status are not automatic, the challenge for policy makers and analysts concerned with achieving food and nutrition security is to understand how these variables are linked to one another, how closely they are...

THE FINANCIAL FEASIBILITY OF ESTABLISHING A FRESH PRODUCE PACKING HOUSE IN JORDAN
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Hattar,   Raed F.; Bacon,   J. Richard; Toensmeyer,   Ulrich C.; Gempesaw,   Conrado M., II.
Historically, Jordan's traditional markets for fresh produce have been the Persian Gulf countries.  However, these exports have declined in recent years and new markets in Europe have been tapped.  One of the main constraints to expanding the European market is the lack of quality-oriented packing houses in Jordan.  This study considers the feasibility of a vegetable packing house designed to meet the quality requirements of the European market.  The overall objective is to evaluate the economic viability of packing and transporting various fresh produce items to the European market.  Specifically, four transportation scenarios were evaluated using a comprehensive firm-level, dynamic and stochastic, multiple-year, capital budgeting computer simulation...

STOCHASTIC SIMULATION OF A SMALL-SCALE MEAT PACKING PLANT
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Falk,   Constance L.
A small-scale meat packing plant selling lambs and steers in northern New Mexico was analyzed in three Monte Carlo simulations.  The monthly distributions of steer liveweights and prices at the feedlot were fit and the parameters estimated.  The distributions were correlated between liveweights and prices each month and between all monthly prices.  An annual distribution of lamb liveweights was also fit.  The three simulations assumed that retail prices of beef in northern New Mexico were comparable to the national average, minimum and maximum weighted prices.  If minimum national beef prices are used, there is a better than 50 percent probability that net profits will be negative every month except June-September.  In January-May and November, there is a...

AN ANALYSIS OF FARMERS' POLICY ATTITUDES AND PREFERENCES FOR FREE TRADE
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Kastens,   Terry L.; Goodwin,   Barry K.
This study evaluates the attitudes of U.S. (Kansas) farmers regarding "free-trade" and "free-market" policy environments.  In contrast to earlier studies, non-specific policy attitudes are evaluated.  A direct measure of farm program benefits is also included.  Attitudes vary significantly with farm and operator characteristics.  Support for free trade was shown to decrease with education and experience, to increase for farms with relatively more rented land, and to increase as total farm wealth increased.  Support for free-trade was also higher for crop farms.  Farms receiving more government payments are less likely to favor a free-trade policy environment.

The Role of Management Behavior in Agricultural Cooperatives
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Cook,   Michael L.
Mintzburg’s managerial working role model is used to explore the ways roles and behavior of the general manager of a user-oriented firm differ from those of the manager of an investor-owned firm (IOF). It is argued that, in the roles of conflict resolution, resource allocation, information spokesperson, and leadership, the challenges of a user-oriented manager are not only significantly different but often more difficult. It is concluded that managers comfortable with complexity; technical-operation, people-oriented resource allocation; multi-stakeholder communication; and with strong coalition- building skills are most successful in user-oriented organizations.

WHAT DO WE KNOW ABOUT DECISION MAKING UNDER RISK AND WHERE DO WE GO FROM HERE?
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Buschena,   David E.; Zilberman,   David.
This article reviews two major approached used in the past for risk analysis—the expected utility approach and the use of safety rules—and endeavors to reconcile their applicability and use in light of the recent nonexpected utility risk literature and working using the mean-Gini coefficient for risk analysis. This leads to the identification of several “"reduced form”" hypotheses that hold under a variety of theoretical structures and to a discussion of some empirical evidence regarding these hypotheses. The major lesson of recent research of individual behavior under risk is that it is not always consistent with the expected utility approach; in short, there is no generic model for evaluating behavior under risk.

THE POTENTIAL FOR SUPPLY MANAGEMENT OF SOUTHEASTERN SWEET ONIONS
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Epperson,   James E.; Huang,   Wan-Tran.
The degree of effectiveness of a marketing order limiting shipments was examined by simulating prices, shipments, and total revenue.  The results suggest that a supply management marketing order would be beneficial to Southeastern sweet onion producers.  These findings reinforce the importance of a marketing plan for achieving price and revenue goals over the course of a shipping season.  Optimal control appears appropriate as a tool to determine intraseasonal shipment goals for a number of commodities under the umbrella of a marketing order.

Autores: Brown,   Mark G.; Behr,   Robert M.; Lee,   Jonq-Ying.
The question of endogeneity of conditional expenditures, as well as prices, in conditional demand equations for justices is examined.  Both conditional expenditures and prices were found to be uncorrelated with the conditional demand errors, based on Wu-Hausman tests.  Conditional demand error variance/covariance estimates and corresponding Slutsky coefficient estimates were approximately proportional, as predicted by the theory of rational random behavior, further supporting independence of conditional expenditures and conditional errors for juice demands.

Targeting Assistance to the Poor and Food Insecure: A Review of the Literature
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Lundberg,   Mattias K.A.; Diskin,   Patrick K.
Targeting involves the identification and selection of certain groups or households or even individuals, and the distribution of benefits (or costs) to them. Targeting is required because governments face resource constraints, and because households have different needs: some are poorer and more food insecure than others. In general, the managerial costs of targeting increase with its narrowness or intended accuracy, and these costs may exceed the savings achieved by targeting. The benefits of targeting arise precisely because it reduces the size of the target population, and the cost of narrower targeting includes the unintentional exclusion of some of the target population. The literature highlights several factors common to successful public works...

Decision support systems are generally geared to short-term tactical decision making.  As an alternative, this paper develops a mathematical programming model to evaluate long-term strategic alternatives in the context of farm-level agricultural production where a broiler farm considers long-term implications of diversification into commercial aquaculture.  The model considers a ten-year strategic planning horizon, incorporates financial risk and return considerations, and accommodates capacity variations.  Results indicate that a diversification strategy significantly increases farm profitability over a strategic planning horizon while simultaneously maintaining financial risk below a predetermined tolerance level and return on investment above a...

Australian Agricultural Policy Since 1992: New Emphases, Old Imperatives
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Malcolm,   Bill.
Since 1992 there have been some major debates and decisions on Australian agricultural policy issues. Recent policy issues of the dairy, wool, wheat and meat industries are canvassed, as well as current policies on rural adjustment and drought, and the latest policy direction of the National Farmers Federation are documented. Emerging emphases in policy include adding value to commodities, privatization of activities of statutory authorities, and the management of resources and risk by farmers. In agricultural policy formation in 1992-1994 these new emphases confronted the old imperatives of agriculture.

Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Skaggs,   Rhonda K.; Kirksey,   R.E.; Harper,   Wilmer M.
Conservation Reserve Program (CRP) land retirement contracts will begin to expire in late 1995.  A multinomial logit model is used to identify characteristics influencing New Mexico CRP participant post-CRP land use plans.  Results indicate post-CRP land uses intentions will vary with attributes reflecting characteristics of the land enrolled, socioeconomic variables, and participant attitudes.  Results point to a CRP-facilitated retreat from crop production to future ranching by many producers.  The analysis suggests future changes in the structure and character of southern Great Plains agriculture and surrounding communities.

Benefits of Reducing Nutrient Variation in Fertilizer Mixes
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Chamberlain,   Peter J.; Shumway,   C. Richard.
This article examines nutrient deficiencies (below guaranteed levels) in major blended commercial fertilizers and their economic impact on net revenues of Texas farmers. Violations by fertilizer manufactures in meeting specific labeled nutrient levels were more than offset in economic value by excesses in other nutrients and by production of blends that contained more than the required levels of all nutrients. The study concluded that economic losses to Texas farmers would likely be associated with requiring nutrient levels to be more tightly distributed around the guaranteed or labeled nutrient levels.

Breeding for food-staple plant varieties that load high amounts of iron and zinc in their seeds holds great promise for making a significant, low-cost, and sustainable contribution to reducing iron and zinc deficiencies in humans in developing countries. This strategy also may well have important spinoff effects for increasing farm productivity in developing countries in an environmentally-beneficial way. Understanding how household incomes, food prices, and culturally-based preference patterns interact to drive food consumption and nutrient intake patterns can provide crucial background information for designing effective nutrition intervention programs. Research in both of these areas is being pursued under a five-year project organized by the...

THE EFFECTS OF TIME-OF-USE ELECTRICITY RATES ON NEW YORK DAIRY FARMS
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Schenkel,   Mark; Boisvert,   Richard N.
Recent concern among New York dairy farmers has grown regarding potential increases in energy costs as upstate utilities, under mandate from the New York Public Service Commission, move to time-of-use electricity rates. Furthermore, since it is often desirable to maintain relatively fixed intervals between daily milkings, farmers have expressed further concern about their ability to shift electricity consumption from expensive peak period hours to relatively inexpensive off-peak hours. To determine the effects of time-of-use electricity rates on New York dairy farms and to gain a better understanding of methods farmers can adopt to save energy, an empirical model estimating the time-of-day demand for electricity is developed. The parameters from this model...

AN ANALYSIS OF POTENTIAL CONSERVATION EFFORT OF CRP PARTICIPANTS IN THE STATE OF MISSOURI: A LATENT VARIABLE APPROACH
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Kalaitzandonakes,   Nicholas G.; Monson,   Michael J.
This study investigated the influence of economic, personal, and attitudinal factors on the intended conservation effort of a sample of Conservation Reserve Program (CRP) contract holders after their contracts have expired.  Economic factors were found to dominate the decision about future conservation effort.  Attitudes towards conservation were found to have no significant influence on the decision.  This fact may relate to the recent changes in the regulatory environment brought about by the 1985 Food Security Act which changed conservation from a voluntary to regulated nature.

Institutional perspectives of land reclamation operations in Punjab: A case study of the Lower Chenab Canal (East) Circle Area
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Bandaragoda,   Don Jayatissa; Rehman,   Saeed ur.
The Directorate of Land Reclamation (DLR), which was set up in 1945, is a special unit of Punjab's Irrigation and Power Department for undertaking research and field operations to combat the problem of salinity.  Approaching the end of five decades of existence, the directorate is yet to demonstrate its effectiveness in its assigned task; its inability to fully cope with the conditions of a fast changing irrigation environment makes this rather an illusive goal. In the selection of lands for reclamation, the Directorate is heavily dependent on the visual salinity survey (Thur Girdawari) carried out every year by the Irrigation Department's field staff.

The Geographic Structure of Milk Hauling Cost and Efficiencies In New York State
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Erba,   Eric M.; Pratt,   James E.
A survey of the milk haulers in the Northeast was conducted in June 1992 to assess the status of the industry. Detailed information on characteristics of the hauling businesses as well as the equipment operated was collected. Data submitted by milk haulers with New York addresses was isolated from the survey data set and analyzed on a regional basis. Some of the general topics addressed include the number, size, and location of hauling businesses, wages paid to hired drivers, and the cost of milk hauling equipment. A section is devoted to measures of hauling efficiency. Two sections review the costs involved in milk hauling, the first of which is more general in its approach. The second cost-based section investigates differences in hauling costs between...

AN ANNOTATIVE BIBLIOGRAPHY OF RESEARCH ON THE ECONOMIC EFFECTS OF CLIMATE CHANGE ON AGRICULTURE
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Kaiser,   Harry M.
Anthropogenic emissions of carbon dioxide and other "greenhouse" gases have the potential to substantially warm climates worldwide.  While the timing and magnitude of global warming is uncertain, scientists on the Intergovernmental Panel on Climate Change (IPCC) predict that average global temperature may increase by 1.5- 4.5³C (2.7-8.1³F) over the next 100 years. Changes in precipitation will likely accompany any changes in temperature.  However, the magnitude, and even direction of these changes is difficult to predict with much confidence on a regional basis.      The agricultural sector may be profoundly affected by future changes in temperature, precipitation, solar radiation, and carbon dioxide concentrations. Over the past decade, there has been a...

PRICE-LINKED FARM AND SPATIAL EQUILIBRIUM MODELS
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Batterham,   Robert L.; MacAulay,   T. Gordon.
The integration of detailed farm supply models with the basic spatial equilibrium model, is outlined. The direct linking of farm linear programming models with the spatial equilibrium model is achieved so that both prices and quantities are endogenous. Both the farm model and the spatial equilibrium model must be specified in primal-dual form to make the linkages. Limited details of the use of such a model in a study of a segment of the grain handling system in New South Wales are presented along with conclusions relating to the pricing of grain handling services.

FACTORS INFLUENCING FARMERS' SELECTION OF A MILK HANDLER
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Kilmer,   Richard L.; Lee,   Jonq-Ying; Carley,   Dale H.
A structural probit model is estimated to determine the change in the probability of selecting a milk handler.  Cooperatives are thought to have lower prices and higher deductions than independent milk handlers and these factors reduce the probability that a farmer will select a cooperative by 0.39 and 0.32.  Cooperatives are thought to have better services and an assured market and payment than independent mile handlers and these factors increase the probability that a farmer will select a cooperative by 0.20 and 0.26.  This indicates that many cooperative members value monetary characteristics over non-monetary characteristics.

CHANCE CONSTRAINED PROGRAMMING MODELS FOR RISK-BASED ECONOMIC AND POLICY ANALYSIS OF SOIL CONSERVATION
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Zhu,   Minkang; Taylor,   Daniel B.; Sarin,   Subhash C.; Kramer,   Randall A.
The random nature of soil loss under alternative land-use practices should be an important consideration of soil conservation planning and analysis under risk.  Chance constrained programming models can provide information on the trade-offs among pre-determined tolerance levels of soil loss, probability levels of satisfying the tolerance levels, and economic profits or losses resulting from soil conservation to soil conservation policy makers.  When using chance constrained programming models, the distribution of factors being constrained must be evaluated.  If random variables follow a log-normal distribution, the normality assumption, which is generally used in the chance constrained programming models, can bias the results.

Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Kingwell,   Ross S.
Commercial export from Australia of native birds, wild or captive bred, is prohibited. This paper firstly describes the current legislation and regulations that restrict the export of native birds and discusses why governments have adopted such a regulatory approach to bird species preservation. Secondly, the paper reviews the debate concerning the export ban, pointing out strengths and weaknesses in arguments and indicating the important role of CITES. Lastly, the paper outlines a new case for a conditional lifting of the ban, whereby DNA fingerprinting is used to establish transferable property rights to overcome a main source of market failure in the preservation of bird species. Application of this DNA technology offers an opportunity both to protect...

Thinking Critically About Agricultural Issues
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Barkley,   Andrew P.
The agricultural sector of the United States provides an enormous number of issues that require critical thought and evaluation, such as low farm prices, soil depletion, free trade agreements, food safety, rural depopulation, water quality, and farm subsidies. Individuals addressing these issues bring with them different backgrounds, experiences, and perspectives. Often, these differences result in divergent and conflicting opinions on agricultural issues. The objective of this paper is to describe how critical evaluation of agricultural issues in the classroom can lead to greater comprehension, refinement of opinions and ideas, and a passion for lifelong learning. Class discussions and weekly writing assignments on agricultural issues can be used...

THE VALUE OF INFORMATION IN HERBICIDE DECISION MAKING FOR WEED CONTROL IN AUSTRALIAN WHEAT CROPS
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Pannell,   David J.
Most weed control decisions are made with the benefit of some information about weather conditions and actual weed densities. This study is an investigation of the value of adjusting weed control decisions in response to these types of information. For a specific example, it is found that the expected value of information can reach 15% of expected gross margin. The value of information about yield prospects is higher than that for weed density. The value of information is markedly affected by the degree of risk aversion and the type of decision rule adopted. Use of information reduces the expected level of herbicide usage.

SELECTING DELIVERY METHODS FOR OUTREACH EDUCATION PROGRAMS
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Carter,   Bryson R.; Batte,   Marvin T.
Farmer perceptions of extension program delivery methods and an analysis of the relationships of method and farmer characteristics to evaluation scores are presented.  Evaluation scores tend to increase with written, interactive and variable-scheduled methods and methods where users determine the agenda.  Evaluations tend to be lower for high user cost and "high-tech" methods.  Substantial similarity of results exists across groups of farmers differing by age, education levels, farm size and farm type.  There are differences, however, in absolute valuation of the method characteristics across the groups.

THE VALUE OF PLANTING FLEXIBILITY PROVISIONS IN THE 1990 FARM BILL TO THREE REPRESENTATIVE TEXAS FARMS
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Chien,   Ming-Che; Leatham,   David J.
The 1990 Farm Bill reduces deficiency payments but also provides more planting flexibility for program participants.  In this study, a mean-standard deviation analysis is used to analyze the impacts of planting flexibility provisions on crop selection decisions, farm returns, and farm risk.  Results show that gains from the added planting flexibility do not offset the mandatory loss in the deficiency payments for program participants.  Planting flexibility will lead to an increase in corn and wheat planted in the Northern Plains and an increase in cotton planted in the Rolling Plains and Coastal Bend, Texas.

AN EMPIRICAL ANALYSIS OF LOUISIANA SMALL FARMERS' INVOLVEMENT IN THE CONSERVATION RESERVE PROGRAM
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: McLean-Meyinsse,   Patricia E.; Hui,   Jianguo; Joseph,   Randolph, Jr.
The study examines Louisiana small farmers' reasons for not participating in the Conservation Reserve Program (CRP), their awareness of the program, and their willingness to participate in the program.  The results suggest that: farmers do not participate in the CRP if revenues from cropland are an important source of income, or if they are tenants; awareness is significantly related to education, income, race, and average return per acre; willingness is positively influenced by payment per acre, age, and farm status.  Participation depends on whether payments per acre are comparable to the opportunity costs of removing cropland from production.

Little comprehensive research, however, has been done on the effects of those technologies themselves on human fertility -- leaving unanswered the question of whether particular types of agricultural technologies were actually increasing, or decreasing, this demographic "breathing space." This paper uses District-level data from rural India on agricultural change (from 1961 to 1981) and changes in human fertility (from 1971 to 1981) to assess the impact of the former on the latter, with particular emphasis on high yielding (HYV) Green Revolution technologies.

Autores: Osteen,   Craig D.
Pesticide use is regulated within a complex legal framework that includes the Federal Insecticide, Fungicide, and Rodenticide Act; the Federal Food, Drug, and Cosmetic Act; and other environmental laws.  The framework includes risk-benefit rules for some decisions that permit full consideration of comparative performance, cost, and risks of a pesticide and its alternatives before decisions to permit or ban uses.  The framework also includes risk-only standards, such as the Delaney Clause, that prohibit such comparisons and can have unintended and undesirable consequences by increasing health or environmental risks while increasing the cost of producing agricultural commodities.

JAPANESE MEAT IMPORT DEMAND ESTIMATION WITH THE SOURCE DIFFERENTIATED AIDS MODEL
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Yang,   Seung-Ryong; Koo,   Won W.
A source differentiated AIDS model is specified to estimate Japanese meat import demand. Block separability and product aggregation are rejected at conventional levels of significance. The model with the block substitutability restriction explains more than 95% of data variation. The empirical results indicate that the U.S. has the largest potential for beef exports to Japan. Taiwan is in a strong position in the pork market, and Thailand and China are strong in the poultry market. The U.S. competes with Canada and Taiwan in the pork market, but the competition between Taiwan and European countries is the strongest in the market. The U.S. competes with Thailand in the poultry market, where the U.S. is the most vulnerable.

AGRICULTURAL DIVERSITY AND CASH RECEIPT VARIABILITY FOR INDIVIDUAL STATES
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Tauer,   Loren W.; Seleka,   Tebogo B.
Changes in individual states' agricultural production diversity and variance of cash receipts were measured over the 30-year period 1960 through 1989.  Diversity was measured using a general index, of which the inverse Herfindahl and the Entropy are special cases.  Cash receipt variability was measured using a heteroscedasticity correction process.  Although 38 states experienced an increase in cash receipt variability, only 14 states also experienced a decrease in diversification.  Thus, it appears that an increase in cash receipt variability was not due to reduction in diversification for most states.

FACTORS INFLUENCING TECHNOLOGY ADOPTION IN A LOUISIANA AQUACULTURE SYSTEM
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Caffey,   Rex H.; Kazmierczak,   Richard F., Jr.
A multinomial logit model was estimated and used to analyze the impact of various producer characteristics on the adoption of flow-through and recirculating technology in soft-shelled crab production.  Because of the industry's geographic isolation and high turnover rate, data was collected by personal interviews in 1991.  The results suggest that increased adoption might be fostered by targeting education programs towards full time, family operated businesses in nontraditional production regions.  However, development of effective education programs may be hindered by the lack of a significant relationship between producer adoption decisions and the information provided by university or extension personnel.

Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Ribaudo,   Marc; Bouzaher,   Aziz.
Restricting or eliminating the use of atrazine in the Midwest would have important economic consequences for farmers and consumers. Atrazine is an important herbicide in the production of corn and other crops in the United States. Since atrazine is such an important herbicide, mandatory changes in application strategies are likely to generate sizable costs for producers and consumers. However, recent findings indicate that elevated amounts of atrazine are running off fields and entering surface water resources. This report presents the costs and benefits of an atrazine ban, a ban on pre-plant and pre-emergent applications, and a targeted ban to achieve a surface water standard. A complete atrazine ban is hypothesized to be the costliest strategy, while the...

The consumer cooperative movement is the largest mass organisation in Japan, with more members than the agricultural cooperatives and trade unions. With the opening of the Japanese market to food imports, consumer cooperatives will play an increasingly important role. They will form relationships with foreign suppliers that will give these suppliers access to their members - a group of consumers who are perhaps the most affluent and discerning of Japanese consumers. They will require that their foreign suppliers produce products with residue levels lower than those the Japanese government sets. They may also apply pressure to foreign suppliers to adopt practices that are environmentally friendly.

ENVIRONMENTAL AND ECONOMIC IMPACTS OF AGRICULTURAL POLICY REFORM: AN INTERREGIONAL COMPARISON
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Painter,   Kathleen M.; Young,   Douglas L.
Mathematical programming results revealed that moving toward more flexible agricultural policies would generate substantial economic and environmental gains in a North Carolina diversified cropping region.  But in a Washington-Idaho dryland grains region, only the use of relatively new and sometimes problematic alternative cropping systems permitted environmental and economic gains under policy reform.  In both regions, a recoupling policy, which links government payments to resource-conserving farming practices, was needed to protect environmental quality when market prices for program crops were high.

A LOGIT ANALYSIS OF PARTICIPATION IN TENNESSEE'S FOREST STEWARDSHIP PROGRAM
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Bell,   Caroline D.; Roberts,   Roland K.; English,   Burton C.; Park,   William M.
This study determines the likely effect of cost-share incentives on participation in the Tennessee Forest Stewardship Program and identifies other factors that may contribute to participation.  A random utility model is used to determine the probability that a landowner will choose to participate in the program.  A binary choice model is specified to represent the dichotomous decision and a logit procedure is used to fit the model. Data are obtained from mail surveys of 4,000 randomly selected landowners.  Results indicate that attitudes and knowledge of forestry programs may be more influential in a landowner's decision to participate than monetary incentives.

This article compares willingness-to-pay (WTP) estimates from an actual survey using a checklist question regarding WTP for groundwater quality improvements to WTP estimates that would have been obtained had a single-bounded referendum (SBR) or a double-bounded referendum (DBR) question been asked.  Results indicate differences among estimates from the three types of question formats.  There was a loss of statistical efficiency of parameter and WTP estimates when moving from the checklist and DBR formats to the SBR format.  WTP estimates from the SBR question were more sensitive to sample size and model specification than the others.

THE TRADE AND ENVIRONMENTAL DEBATE: RELEVANT FOR SOUTHERN AGRICULTURE?
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Marchant,   Mary A.; Ballenger,   Nicole.
This paper introduces and briefly discusses the economics of two important trade and environment policy issues--international harmonization of environmental standards and the use trade measures for environmental purposes.  Both issues are likely to generate lively international debate among environmentalists, industry representatives, and trade negotiators over the next few years.  As the international community seeks new multilateral rules in these areas, agricultural producers will want to know how they will be affected.  Thus, this paper also examines the potential impacts of environmental policy on the competitiveness of commodities unique to the Southern region of the United States.

Optimal exploitation of renewable groundwater resources when extraction affects the probability of occurrence of an irreversible event is studied. The term irreversible signifies that the event occurrence renders the resource obsolete. It is found that uncertainty concerning the event occurrence has a profound effect. Under certainty - when the stock level below which the event occurs is known in advance - the optimal state process converges to a unique equilibrium state. Under uncertainty, when the event occurrence level is unknown, we identify equilibrium intervals and show that optimal processes initiated elsewhere converge to a boundary of one of these intervals. Inside an equilibrium interval, the expected loss due to the event occurrence is so high...

Real and ideal water rights: the prospects for water-rights reform in Israel, Gaza, and the West Bank
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Berck,   Peter; Lipow,   Jonathan.
The ideal water contract for a heterogeneous population of users is a prioritized right that is fully vested and fully tradable. A set of tradable, prioritized rights contracts will span the same space as the Debreu contingent commodities. Therefore, they lead to a competitive equilibrium that is Pareto optimal. Equal sharing of water shortfalls does not have this property.  Existing water policies in Israel and the Disputed Territories are not characterized by an efficient set of water contracts. The system misallocates water over both time and space.  Current policies are driven by strategic and ideological objectives. With peace, reform of water policies will become politically feasible. The paper concludes with a proposal for a new water-allocation...

FOOD PROCESSORS' LOBBYING ACTIVITY AND FARM POLICY
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Ndayisenga,   Fidele; Kinsey,   Jean D.
This study tests the hypothesis that lobbying by food firms does not contravene United States farm policy, particularly commodity programs.  The research is important in the analysis and understanding of the difficulties of designing and reforming agricultural policies. If farm programs significantly benefit downstream food firms, there is effectively no countervailing power to the farm lobby because (1) farm input supply and marketing firms have been shown to benefit from existing farm policies - and have therefore no incentive to lobby against the policies - and (2) consumers and taxpayers, two important stakeholders in agricultural policies, are known to be quite inefficient in lobbying due to their "large-group" characteristics. Information on food...

THE FINANCIAL SUSTAINABILITY OF WATER SUPPLY AND SANITATION SERVICES:  A FRAMEWORK FOR ANALYSIS
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: McVeigh,   Paul.
This paper outlines a framework that will facilitate the assessment of the financial sustainability of proposed improvements in water and sanitation facilities.  Financially sustainable services are those in which the revenues generated from the service users exceed the cost of providing the service.  This analytical framework identifies the levels or amounts of the service that can be financially self-supporting.  It will also reveal the extent of any subsidy that would be required for levels of the service at which the costs to provide the service exceed the revenues that can be generated.  The framework that is used is the conventional supply and demand model of microeconomic theory.  Three case studies illustrate how data from contingent valuation...

DAIRY HERD MANAGEMENT PRACTICES FOCUSING ON PREWEANED HEIFERS
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Ott,   Stephen L.
The National Dairy Heifer Evaluation Project ( NDHEP ) was conducted by the National Animal Health Monitoring System (NAHMS ) from April 1991 through July 1992 with the assistance of 1,811 producers from 28 states. Producers included in the study each had herds of 30 or more milk cows, representing 78 percent of the milk cows in the U.S. The average total of cattle and calves on each operation was 169.4. The main breed on 94.9% of operations was Holstein. Slightly over 46 percent of operations stated reproductive problems as the cause of low milk production of cows culled from the herd. Newborn calves were separated from their mothers before nursing on 28.0 percent of operations and less than 12 hours after birth on 39.6 percent of operations. On 64.0...

The optimal suppression of a low-cost technology by a durable-good monopoly
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Karp,   Larry S.; Perloff,   Jeffrey M.
If a durable-good monopoly can use either of two technologies whose properties are known to consumers, the monopoly uses only the technology with the lowest average cost at low levels of production. If consumers only know about technologies in use, the monopoly may use an inferior technology initially to increase its profits, keeping the new, efficient technology secret and switching later. Thus, in either case, an inferior technology may be used; however, switching between technologies occurs only if consumers are not fully informed about both technologies.

A COMPARISON OF DEMANDS FOR MEAT PRODUCTS IN THE PACIFIC RIM REGION
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Capps,   Oral, Jr.; Tsai,   Reyfong; Kirby,   Raymond; Williams,   Gary W.
The Rotterdam model is used to obtain estimates of demand parameters for meat products in Taiwan, South Korea, and Japan.  Unlike most previous studies of demand systems, the model takes into account simultaneous-equation bias which arises due to the endogeneity of total expenditure.  Beef, pork, and chicken are separable from marine products for each Pacific Rim country.  However, demand elasticities for beef, pork, and chicken are different among the various Pacific Rim nations.  One may not then use the elasticity estimates of a particular country and apply them to other Pacific Rim markets.

AMENITY BENEFITS AND PUBLIC POLICY: AN APPLICATION TO THE CONNECTICUT DAIRY SECTOR
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Lopez,   Rigoberto A.; Altobello,   Marilyn A.; Shah,   Farhed A.
This article develops a conceptual framework for analyzing the role of state-level policies towards the dairy sector in the presence of farmland amenity benefits, and applies it to Connecticut.  Milk supply, demand and amenity benefit functions are estimated, and three exogenously determined milk prices are considered.  The empirical findings show, under each price scenario, the extent to which land is underallocated to the dairy sector if amenity benefits are ignored.  Analysis of policy options reveals that a partial production cost subsidy represents the least-cost alternative for attaining the socially optimal solution for the region.

Cooperatives are unique business organizations. Many of their unique characteristics have a direct impact on how decisions are arrived at as well as the ultimate decision made. This study reviews current literature on cooperatives and decision making. A decision making model is developed to arrive at a set of provisional hypotheses. Fourteen U.S. agricultural cooperatives were studied through interviews with chief executive officers and chairpersons of the board of directors. The organizations in the sample were selected by volume of business, tenure of executives, successful performance and type of organization. Cooperatives in the sample were larger and on average better endowed with resou rces to focus on making informed decisions than the general...

DESIGNING GREEN SUPPORT: INCENTIVE COMPATIBILITY AND THE COMMODITY PROGRAMS
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Runge,   C. Ford.
The purpose of this brief analysis is to consider the potential points  of contact between a program of "green support" and the existing commodity programs in U.S. agriculture.  These points of contact may      take the form of conflict, complementarity, or neutrality.  We shall assume initially that green support is "added" to the programs as they exist in 1994.  Five main commodity program areas are considered:       A. Deficiency payments resulting from the loan rate/target price structure       B. Acreage reduction programs (ARPs) operating in conjunction with A.        C. Conservation compliance, sodbuster and swampbuster programs        D.

Mathematical programming models, as typically formulated for international trade applications, may contain certain implied restrictions which lead to solutions which can be shown to be technically infeasible, or if feasible, then not actually an equilibrium. An alternative formulation is presented which allows joint-inputs and multi-products, with pure transshipment and product substitution forms of arbitrage.

EFFECT OF RISK AVERSION ON FEEDER CATTLE PRICES
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Lee,   Jung-Hee; Brorsen,   B. Wade.
This paper determines the effects of cattle feeders' risk aversion on feeder cattle prices using pen data of Kansas feedlots.  Higher profit risk results in lower feeder cattle prices.  The elasticity of feeder cattle price with respect to profit risk was small (-0.013).  The risk elasticity estimated here is similar to risk elasticities in previous studies and thus, the use of pen-level data does not seem to add much to the study of risk.

Factors affecting the frequency of purchase of fish and other seafood for at-home and restaurant consumption by Northeastern consumers were investigated.  Cluster analysis identified six groups of consumers with similar perceptions of the attributes of fish.  Demographic and cluster membership variables were employed in logistic regressions to identify the characteristics of frequent at-home use and restaurant purchasers.  At-home purchase was more likely to be frequent among respondents with white collar occupations, older ages, urban/suburban and New England residence, recreational fishing participation, and membership in one of five attitudinal clusters.  Restaurant purchase was more likely to be frequent among whites and among those with higher...

Marketing Australia's Wheat Crop: The Way Ahead
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Ryan,   Timothy J.
The 1989 Wheat Marketing Act has set in motion forces, in particular the deregulation of the domestic market for wheat and the establishment of the Wheat Industry Fund, which have irrevocably altered the way in which wheat and other grains are marketed in Australia. This article examines these forces and subsequent developments and seeks to address which marketing structure is best suited to maximise the position of Australian growers into the next century. Using some tenets drawn from industrial organisation economics, the international grain market and the current Australian system are discussed. Some benefits from the operation of the Australian Wheat Board are postulated and a discussion of continuing developments possibly leading to a corporatised AWB...

Fresh Fruit and Vegetable Procurement Dynamics: The Role of the Supermarket Buyer
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: McLaughlin,   Edward W.; Perosio,   Debra J.
Over the past several decades, the fresh fruit and vegetable industry has been one of the most dynamic sectors in the U. S. food system. Consumer demand has soared to record levels and both suppliers and distributors have responded with impressive new programs, products and technologies. The objective of this report is to provide critical information on one of the most influential but least studied elements of the produce system: the supermarket produce buyer. This buyer represents the "gate-keeper" between the supply end of the distribution channel and the supermarket shelves. His standard operating practices (SOPs) and decisions have an enormous influence on industry performance. A "framework" for produce buying and selling SOPs is set forth in Section...

In this paper we present measures of land and labor productivity for a group of 98 developed and developing countries using an entirely new data set with annual observations spanning the past three decades.  The substantial cross-country and intertemporal variation in productivity in our sample is linked to both natural and economic factors.  We extend previous work by dealing with multiple sources of measurement error in conventional agricultural inputs when accounting for observed differences in productivity.  In addition to the mix of conventional inputs in agriculture, we find that indicators of quality change in these inputs and the amount of publicly provided infrastructure are significant in explaining cross-sectional differences in productivity...

Lifting the Wool Curtain: Recent Reforms and New Opportunities in the Chinese Wool Market with Special Reference to the "Up-country" Mills
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Brown,   Colin G.; Longworth,   John W.
From being an insignificant buyer of Australian wool at the start of the 1980s, China had emerged as Australia's major, if somewhat erratic, customer by the 1992/93 season. Continued development of Sino-Australian trade in wool is vital to the future of the Australian wool-growing industry. This article describes recent market and trade reforms in China and examines their likely impact on wool imports. Particular attention is devoted to the effects the recent changes will have on the up-country mills which represent a poorly understood but potentially significant new market for Australian wool. In many respects the problems/opportunities identified in relation to the up-country mills also exist for many other mills in China which, for various reasons, have...

Biotechnology is expected to produce significant economic and environmental benefits as a result of the development of new varieties of plants and animals and improved agricultural productivity. Seen by many as a key technology for the 21st century, and as an economic stimulus for the State of New Jersey and for the Nation, biotechnology has been the subject of intense scientific and public debate. Yet, while experts and activists continue to argue, genetic engineering techniques are already leading to agricultural products that may soon be on supermarket shelves.

A number of factors including budget pressures, emphasis on environmentally sensitive agriculture, emphasis on finding agricultural export markets, and anti-agricultural program sentiment have fueled a climate for change in United States agricultural policy. Whether significant changes will occur depends on the political strength of agricultural interest groups and on the compromises which can be reached between them.  Several notable achievements have been accomplished in recent domestic agricultural policy legislation.  The 1995 farm bill will define the commodity and conservation programs for the next five years. In addition to domestic developments, there have been history-setting accomplishments in reducing barriers to international agricultural...

LOW CAPITAL DAIRY STRATEGIES IN WISCONSIN:  LESSONS FROM A NEW APPROACH TO MEASURING PROFITABILITY
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Barham,   Bradford L.; Chavas,   Jean-Paul; Klemme,   Richard M.
This paper proposes a new way to evaluate the role of profitability and risk in the dairy industry, one that incorporates the effects of uncertainty about future returns when investments are irreversible, or sunk. The usefulness of this new approach is demonstrated by the light it sheds on recent attempts by Wisconsin dairy farmers to develop low capital investment strategies and why these initiatives might be crucial to the vitality of the state's industry as a whole. The value of this paper, however, reaches beyond the contribution it offers to comparisons of the viability of alternative investment strategies in dairy, because it is applicable to evaluating profitability and risk in any economic activity, inside or outside of agriculture, where much of...

Autores: Clay,   Daniel C.; Guizlo,   Mark; Wallace,   Sally.
In this paper, we argue that there exist no significant direct links between human populations and their environments and that the intervening processes create the context within which land degradation occurs.  We examine some of the intermediate mechanisms through which mounting demographic pressure leads to soil erosion and the depletion of soil fertility.  The focus of attention is on set of variables defined in this paper as the structure of landholding (size of holdings, fragmentation/ dispersion, fragility, tenure, etc.).  How demographically-induced changes in the structure of land-holding affect land management strategies (investments and land use) is key to understanding land degradation.  Traditional perspectives on population and agricultural...

ESTIMATING CORN YIELD RESPONSE MODELS TO PREDICT IMPACTS OF CLIMATE CHANGE
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Dixon,   Bruce L.; Hollinger,   Steven E.; Garcia,   Philip; Tirupattur,   Viswanath.
Projections of the impacts of climate change on agriculture require flexible and accurate yield response models.  Typically, estimated yield response models have used fixed calendar intervals to measure weather variables and omitted observations on solar radiation, an essential determinant of crop yield.  A corn yield response model for Illinois crop reporting districts is estimated using field data.  Weather variables are time to crop growth stages to allow use of the model if climate change shifts dates of the crop growing season.  Solar radiation is included.  Results show this model is superior to conventionally specified models in explaining yield variation in Illinois corn.

AN INDUSTRY PERSPECTIVE OF ALTERNATIVE PORTS OF ENTRY FOR LATIN AMERICAN FRUIT AND VEGETABLE IMPORTS
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Hinson,   Roger A.; Lambert,   Bruce; Picha,   David H.
Trade is a venue for economic development and diversification.  U.S. concerns focus on exports.  However, imports of counter-seasonal produce items stimulate port activity.  At ports used for these products, a marketing infrastructure develops that can be useful to the domestic produce industry.  Most imported produce enters at Miami or along the Delaware River.  Use of Gulf of Mexico ports could shorten transportation distance for Latin American product destined for Southern and Midwestern U.S. markets.  This paper reports results of a survey designed to reveal industry perceptions of the physical and marketing infrastructure, and marketing advantages and constraints, offered by selected Gulf ports.

Autores: Miller,   Lynn H.; Sherrick,   Bruce J.
A multi-factor capital asset pricing model is used to examine the return characteristics of physical assets comprising the farm asset portfolio. Physical assets analyzed are: 1) farm real estate; 2) machinery and motor vehicles; 3) crops stored on farm; and 4) livestock and poultry. Results for the years 1950-1990 indicate that unexpected inflation is more appropriate than the more commonly used realized inflation factor; and that the systematic risk component to these asset classes is, in general, low. Further, excess returns measures are significant for farmland, machinery, and crops stores on farm but not for livestock and poultry.

TECHNOLOGICAL CHANGE AND AGRICULTURAL TRADE PATTERNS
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Salvacruz,   Joseph C.
An international trade model which explains trade patterns of processed foods relative to textiles using relative technological change and relative factor endowments was developed.  This model was tested in the case of the United States and a number of ASEAN countries.  Results indicate that exogenous technology drives the trade pattern of the Asian Newly Industrializing Countries (NICs) while endogenous technology drives the trade patterns of the lesser developed ASEAN countries.  Significant determinants of endogenous technology were identified: foreign aid flows, research and development expenditures, and market power.  Two significant issues were raised in the course of the analysis: (1) the effectiveness of U.S. foreign aid package in developing the...

FARM-LEVEL EVALUATION OF ALTERNATIVE POLICY APPROACHES TO REDUCE NITRATE LEACHING FROM MIDWEST AGRICULTURE
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Swinton,   Scott M.; Clark,   David S.
Policies to reduce nitrate leaching are evaluated using a mixed integer linear programming model of a representative Michigan cash grain farm.  At spring 1993 prices, elimination of the current deficiency payment program is found to be more efficient at reducing leaching than a nitrogen input tax, a tax credit on biologically fixed nitrogen, a rotation payment, or obligatory use of the Integrated Farm Management Program Option (IFMPO).  However, elimination of the deficiency payment program would significantly reduce farm income.  Modeling risk management and nitrate leaching dynamics are useful extensions of this research, as is estimating the benefits from averting nitrate leaching.

CAN PRICE SUPPORTS NEGATE THE SOCIAL GAINS FROM PUBLIC RESEARCH EXPENDITURES IN AGRICULTURE?
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: de Gorter,   Harry; Swinnen,   Johan F.M.
The burgeoning literature on how the benefits from research may be negative for a given price support arbitrarily ignores the costs of price supports for a given level of research. Furthermore, the very existence of price supports is inconsistent with the normative criterion that governments simply maximize social income. We show that there are always gains from research, even if governments maximize social income subject to a farm income goal. Our results are also consistent with the statements made by Schultz and Ruttan that ignoring price supports will result in all over (or under) valuation of research benefits. Finally, we indicate that the predictions of the "no gains from research" literature may not be substantiated by empirical evidence and that...

THE EFFECTS OF INCLUDING BANKRUPTCY ON DYNAMIC INVESTMENT DECISIONS
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Novak,   Frank S.; Schnitkey,   Gary D.
This article evaluates the effects of including the costs of bankruptcy in a dynamic model of off-farm investment decisions using a stochastic dynamic programming (SDP) model which incorporates the stochastic dynamic nature of investment returns and the interrelationships between financial structure and investment decisions.  Our results suggest that in the presence of bankruptcy, optimal investment decisions are affected by financial structure and financial market conditions.  Ignoring bankruptcy costs in determining investment decisions results in a high probability of bankruptcy.

Market-Oriented Strategies to Improve Household Access to Food: Experience from Sub-Saharan Africa
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Jayne,   Thomas S.; Tschirley,   David L.; Staatz,   John M.; Shaffer,   James D.; Weber,   Michael T.; Chisvo,   Munhamo; Mukumbu,   Mulinge.
The objectives of this report are to identify market-oriented strategies to alleviate both chronic and transitory food insecurity, and to examine the interactions between short-run targeting mechanisms and longer-run strategies designed to alleviate the chronic causes of inadequate access to food. The main premise of the report is that sustained improvements in household access to food in Sub-Saharan Africa require the development of more reliable food and input markets that (a) create incentives to adopt cost-reducing investments at various stages in the food system; and (b) offer incentives for rural households to shift from a subsistence-oriented pattern of production and consumption to more productive systems based on specialization and gains from...

Cash Wheat Marketing: Strategies for Real People
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Brorsen,   B. Wade; Anderson,   Kim B.
A new paradigm is needed in extension marketing programs. Attempts to help producers time the market, either through cask sales or futures trading, appear to be of little benefit. Marketing extension programs need to place less emphasis on outlook and futures trading and more emphasis on simple marketing strategies that people really use. An empirical example of strategies for Oklahoma wheat producers shows selling cash wheat at harvest and participating in government programs as the preferred marketing strategy.  Implications for extension programs in other states are that extension programs can help producers decide whether to store their grain and whether to participate in farm programs.

Autores: Liapis,   Peter S.
A net trade model that includes environmental variables is used to analyze economic and environmental implications of various EC policies.  There are environmental benefits from CAP reform, but a fertilizer tax results in greater nitrate and phosphate abatement.  The input tax also results in smaller drops in EC farm income compared to CAP reform.

Rice Self-Sufficiency in Papua New Guinea
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Gibson,   John.
Policy makers in Papua New Guinea want to increase rice self-sufficiency. Food security has been cited as a reason, because the recent fall in the world price for tree crops causes rice imports to make a larger call on scarce export earnings. Analysis of the long run trend in the terms of trade between rice and tree crops suggests that rice self-sufficiency will not produce a sensible allocation of resources. The falling relative price of rice makes it is more efficient to devote resources to expansion of exports, particularly cocoa and coffee, in order to import rice.

A PRIMAL-DUAL APPROACH TO NONPARAMETRIC PRODUCTIVITY ANALYSIS: THE CASE OF U.S. AGRICULTURE
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Chavas,   Jean-Paul; Cox,   Thomas L.
Nonparametric methods for measuring productivity indexes based on bounds for the underlying production technology are presented. Following Banker and Maindiratta, the lower bound is obtained from a primal approach while the upper bound corresponds to a dual approach to nonparametric production analysis. These nonparametric bounds are then used to estimate input-based and output- based distance functions. These radial measures provide the basis for measuring productivity indexes. Application to times series data on U.S. agriculture indicates a large gap between the primal lower bound and the dual upper bound. This generates striking differences between the primal and dual nonparametric productivity indexes.

MODELS OF INTRAHOUSEHOLD RESOURCE ALLOCATION: ASSUMPTIONS AND EMPIRICAL TESTS
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Doss,   Cheryl R.
This paper reviews and analyzes a literature that examines the  restrictiveness of focusing on households as single units of analysis.   In particular, this literature asks:  To what extent can we use the household as a unit of analysis, and when do we need to disaggregate the household and look at individual behavior within the household?  In this paper, I examine the different models of intrahousehold resource allocation and the empirical work they have generated.  Each of the models has a different set of assumptions about the four components of household decisions.  The assumptions and predictions of each of the main models of intrahousehold resource allocation are presented; then I discuss the empirical work that tests the validity of the assumptions...

COMPARATIVE COSTS OF DAIRY MARKETING IN NORWAY AND THE U.S.
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Hoveid,   Oyvind; Hammond,   Jerome W.
Technical marketing efficiency is an important component of comparative  advantage that countries may possess in food marketing. This aspect of marketing efficiency may be affected by size of market(s), technology  used, input costs, and institutional factors. With regard to the latter, Norwegian policy makers have asked whether the extensive regulation and monopolization by a single processing cooperative in the Norwegian dairy sector have resulted in technical inefficiency that leads to excessive costs of milk marketing. Excessive marketing costs could have three important impacts; increased prices for domestic consumers, reduced prices for farmers, and reduced competitiveness in international markets.  International competitiveness is critical for...

AN ADAPTIVE MODEL OF PERISHABLE INVENTORY DISSIPATION IN A NONSTATIONARY PRICE ENVIRONMENT
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Vukina,   Tomislav; Anderson,   James L.
The paper develops an adaptive model of perishable commodity dissipation based on the individual's price expectations and risk perception.  A two-step, state-space procedure for modeling nonstationary time series is presented.  The method combines an impulse response model for estimating deterministic components with an innovations model for the remaining stationary stochastic noise.  Combined parameters are used to generate forecasts and to derive a measure of risk in a nonstationary price environment.  Defined as the variance (covariance) of out-of-sample forecast error, the measure of risk is the difference between the historical estimate of the stationary noise auto-covariance and the variance (covariance) of out-of-sample forecasts.  The optimal...

LONG-TERM PLANNING OF A LIVESTOCK-CROP FARM UNDER GOVERNMENT PROGRAMS
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Kouka,   Pierre-Justin; Duffy,   Patricia A.; Taylor,   C. Robert.
Optimal crop and livestock mix was determined for a representative Alabama farm using a dynamic programming model.  Results indicate that decisions concerning livestock production are highly influenced by the amount of cotton base available on the farm.  In most cases, increasing cotton base results in less cattle production.  The triple base provisions of the 1990 Farm Bill, however, may give some cotton farmers an incentive to produce more stocker cattle during the winter months.  Research results also indicate that the availability of farm programs can alter the optimal enterprise mix on a farm with no beginning base in cotton.

LABOR ADJUSTMENT AND GRADUAL REFORM: IS COMMITMENT IMPORTANT?
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Karp,   Larry S.; Paul,   Thierry.
We analyze a model in which a government uses a second best policy to affect the reallocation of labor, following a change in relative prices. We consider two extreme cases, in which the government has either unlimited or negligible ability to commit to future actions. We explain why the ability to make commitments may be unimportant, and we illustrate this conjecture with numerical examples. For either assumption about commitment ability, the equilibrium policy involves gradual liberalization. The dying sector is protected during the transition to a free market, in order to decrease the amount of unemployment Our results are sensitive to the assumptions about migration.

SCANNER DATA: NEW OPPORTUNITIES FOR DEMAND AND COMPETITIVE STRATEGY ANALYSIS
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Cotterill,   Ronald W.
This paper reviews prior research by agricultural economists on the demand for food products using scanner data.  Thereafter, a differentiated product's oligopoly model with Bertrand price competition is developed and used to specify brand level demand and oligopoly price reaction equations.  The model has sufficient detail to estimate brand level price elasticities and price response elasticities which in turn can be used to estimate three indices of market power.  The first index estimated is the familiar Rothschild Index.  The paper develops estimates two new indexes, the observed index and the Chamberlin quotient for tacit collusion.  It concludes with comments on how the proposed method for the measurement of market power in a differentiated oligopoly...

Agricultural Research Impact Assessment: The Case of Maize Technology Adoption in Southern Mali

Adoption of the improved maize package was particularly rapid during the period 1980-86 when an attractive guaranteed price was offered and extension activities were reinforced by a maize project that included the establishment of a seed multiplication program. Following cereal market price liberalization in 1986, maize prices fell and have been subject to considerable variability. Area has continued to expand, but farmers have greatly reduced fertilizer use, switched back to maize-late millet intercropping, and substituted early maturing varieties better suited to their own food security needs. The estimated internal rate of return (IRR) to investment in maize research and extension in southern Mali over the period 1969-90 is 135%. This high rate can be...

CONSUMER AND FOOD STORE MANAGER PERCEPTIONS OF FOOD INSPECTION REQUIREMENTS
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Potakey,   Harold; Schupp,   Alvin R.; Montgomery,   Donna E.
Federal and state governments operate inspection systems to help assure consumers of the wholesomeness and cleanliness of food products.  Each major outbreak of human illness attributed to foodborne pathogens or to cancer-causing residues in foods raises questions as to the effectiveness of this food inspection.  How do food store managers and consumers differ in their perceptions of needed food inspection?  Mail surveys of households and food stores in three urban and five rural Louisiana parishes in 1992 provided data on consumer perceived inspection requirements for domestically processed seafood, imported seafood and red meats, and for maximum permissible content of cancer-causing substances.

A survey of 139 men and 123 women in four communities bordering Los Haitises National Park in the Dominican Republic took place in late 1992.  The survey followed a presidential decree ordering the army to clear the forest of people and cattle and to resettle a number of villages.  The survey found that people admitted using the forest for firewood and cash crop cultivation.  However, they were aware of the need to conserve the forest and expressed willingness to compromise on its use.  They were less aware of park boundaries and did not understand the concept of a national park.  Villagers welcomed rapid population growth, and women favor (and have) large families despite high rates of sterilization.  Nearly everyone opposed resettlement and favored...

SUSTAINABILITY ISSUES: HOW SHOULD GOVERNMENT COORDINATE FARM REGULATIONS AND POLICY?
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Johnson,   Larry A.
Agricultural sustainability is an evolving process ever-seeking a balance between society's economic, environmental and social demands.  Governmental policy and regulations while attempting to correct adverse externalities, have at times within themselves created adverse externalities.  Failures often lie within the policies themselves, but poor coordination among government agencies is also at fault.  This paper outlines a number of coordination issues and attempts to show how the empowerment of communities through ecosystem management is a partial solution to environmental degradation.

Determinants of credit rationing: a study of informal lenders and formal credit groups in Madagascar
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Zeller,   Manfred.
Previous research on the determinants of credit rationing exclusively focused on the behavior of formal lenders who contract directly with an individual borrower. Based on a household survey in Madagascar, this paper presents an analysis of credit rationing behavior by informal lenders and by members of community-based groups that allocate formal group loans among themselves. The results show that group members obtain and use locally available information about the applicant's creditworthiness in much the same way that informal lenders do. This paper therefore empirically confirms theoretical arguments made that community-based groups have an information advantage over distant formal bank agents.

Effects of the Boll Weevil Eradication Program on Alabama Cotton Farms
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Duffy,   Patricia A.; Cain,   Danny L.; Young,   George J.; Wetzstein,   Michael E.
Five-year, 0-1 mixed integer programming models of two representative Alabama farms were developed for analyzing the effects of the Boll Weevil Eradication (BWE) program on farm program participation and crop-mix decisions by Alabama cotton farmers. In previous research the BWE program was found to increase yields by approximately 100 pounds per acre in Georgia and southern Alabama where the program has been in effect for several years. In this study, these increased yields are shown to be an important factor contributing to the expanded cotton acreage in southern Alabama. For northern Alabama, gains to producers are also possible, but not to the extent realized in the southern part of the state.

DEMAND FOR WHEAT CLASSES BY PACIFIC RIM COUNTRIES
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Wilson,   William W.
The transcendental logarithmic function is used to derive demand functions which are estimated for wheat classes imported by Pacific Rim countries.  Results indicate substantial differences exist in underlying demand parameters for wheat of different classes as well as across countries.  In addition, the expenditure level has important impacts on the distribution of imported wheat classes, and preferences have shifted significantly through time, generally toward higher protein wheats.

AN ANALYSIS OF U.S. DAIRY POLICY DEREGULATION USING AN IMPERFECT COMPETITION MODEL
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Suzuki,   Nobuhiro; Kaiser,   Harry M.; Lenz,   John E.; Forker,   Olan D.
An imperfect competition model of the U.S. milk market is developed for analyzing the impacts of dairy policy deregulation.  Estimated degree-of-competition parameters indicate that the U.S. milk market has become more competitive over time.  The usefulness of the model is demonstrated by showing the relative differences of dynamic simulation results of the imperfect competition model with the results of a conventional exogenous fluid differential model.

SUBSIDIES, ENDOGENOUS TECHNICAL EFFICIENCY AND THE MEASUREMENT OF PRODUCTIVITY GROWTH
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Lachaal,   Lassaad.
The impacts of program subsidy on productivity growth is investigated in this study Mundlak's concept of endogeneity is applied to technical efficiency and generalized within a dual framework.  Technology is described by an aggregate cost function while technical efficiency is conditional on a vector of state variables.  Empirical evidence from the U.S. dairy sector supports the hypothesis that protectionism, in the form of program subsidy, is the source of considerable technical inefficiencies.

STRUCTURAL ADJUSTMENT AND AGRICULTURAL EXPORT RESPONSE IN LATIN AMERICA
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Markussen,   Kristin A.; Lee,   David R.
Expanding exports has been one of the principal goals of structural adjustment programs aimed at restoring external balance of payments equilibria in many developing countries. This paper analyzes the changing responsiveness of agricultural exports to price and exchange rate variation for selected crops in eight Latin American countries over the period 1961-1990. The results show that: (1) commodity and country disaggregation in estimation generates much higher export response elasticities than previously estimated; (2) real exchange rate changes dominate price changes in stimulating export response; and (3) statistical tests confirm structural change in export response elasticities in over half of the equations estimated. Overall, the evidence suggests...

The recently completed round of negotiations under the General Agreement on Tariffs and Trade focused on domestic and international agricultural policies. If this agreement is approved by Congress, U.S. agricultural programs must comply with GATT provisions.  The policy choices made during the 1995 farm bill debate about domestic programs, import policies, and export programs could all be affected by the approval of GATT.

SIMULTANEITY OF TECHNOLOGY ADOPTION AND PRODUCTIVITY
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Zepeda,   Lydia.
A simultaneous equation generalized probit model is estimated to determine factors affecting technology adoption by California dairy farmers.  Since productivity and technology choice are jointly determined, a single-equation approach to determine whether productivity affects technology adoption is subject to simultaneity bias.  Since the system of equations contains both continuous and discrete endogenous variables, generalized probit is used.  The findings indicate that the biased single-equation estimates tend to exaggerate relationships with explanatory variables, and in some cases, lead to different implications.  This emphasizes the need to use the consistent and asymptotically more efficient generalized probit results to account for simultaneity.

ALTERNATIVE OLIGOPOLISTIC STRUCTURES IN INTERNATIONAL COMMODITY MARKETS: PRICE OR QUANTITY COMPETITION?
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Carter,   Colin A.; MacLaren,   Donald.
It has been shown in new trade theory that trade taxes/subsidies may be optimal in the case of oligopolistic markets. This result has relevance for international commodity markets because there is growing evidence of imperfect competition in commodity trade. However, it has also been demonstrated that the optimal strategic trade policy depends on whether the market is distinguished by Bertrand (price) or Cournot (quantity) competition. We argue that commodity markets may be characterised by either form of imperfect competition and also by product differentiation. As an illustration, we present a set of models of the Japanese market for beef imports in which account is taken of various forms of strategic interaction between Australian and United States...

NEW ESTIMATES OF WELFARE AND CONSUMER LOSSES IN U.S. FOOD MANUFACTURING
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Connor,   John M.; Peterson,   Everett B.
In the past 15 years, industrial-organization economists have significantly expanded the range of algorithms for calculating welfare losses due to imperfect competition. We compare eleven empirical estimates of economic losses due to market power in 47 U.S. food manufacturing industries, almost all of them previously unpublished. Each of the studies incorporate different theoretical assumptions about demand conditions, supply conditions, or industry pricing behavior; or they utilize various data sources, time periods, and assumptions about the proper competitive benchmark. The estimates of average allocative losses due imperfect competition range from 0.2 percent to an impossibly high 289 percent of industry output; consumer losses range from 6.0 percent...

ALMOST IDEAL AREA YIELD CROP INSURANCE CONTRACTS

Using yield data for a sample of 123 dryland wheat producers in Montana, the effects of three area yield contracts, including the contract currently offered by the United States Federal Crop Insurance Corporation and two individual yield contracts on individual farm yield variability, are examined.  The results indicate that while the Federal Crop Insurance Corporation area yield contract provides all farmers in the sample with some protection against yield variability, a simpler, actuarially equivalent "almost ideal" area yield contract provides substantially larger reductions in yield variability.  However, actuarially equivalent individual yield contracts provide levels of protection against yield variability similar to those obtained under the "almost...

POLICY LESSONS FROM HISTORY AND NATURAL RESOURCE PROJECTS IN RURAL HAITI
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: White,   Thomas A.
The rural population of Haiti is sinking ever deeper into poverty and misery in parallel with the rapid degradation of its agricultural and forest lands.  With essentially no remaining agricultural frontier, no significant value-added products and markets, and very few off-farm employment opportunities, many view emigration as their only hope. This downward spiral of welfare results mostly from taxes on rural production coupled with lack of government investments in rural infrastructure and measures.  Traditional rural institutions that could contribute to development have been seen as a political threat and have been repressed. It is evident from the history of Haiti that even good projects have not made up for bad sectoral policies and repressive...

Impacts of alternative federal milk marketing policies which result in reduced fluid (Class I) milk prices were assessed using a simulation model of the U.S. dairy industry.  Results indicated that milk production, farm milk prices and producer revenues were significantly reduced in the Southern and Northeast regions of the country under some options.  The regional shares of total U.S. milk production were not significantly altered from those which would exist under a continuation of the current policy.

COMMERCIAL AGRICULTURE IN METROPOLITAN AREAS: ECONOMICS AND REGULATORY ISSUES
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Gardner,   Bruce L.
Metropolitan agriculture is economically important, especially in the Northeast.  While faced with substantial economic and regulatory obstacles, commercial farming in urban areas is surviving and even prospering.  In terms of standard models of agriculture in economic development, this is a puzzle.  But more detailed, spatial economic models indicate how labor-intensive production of perishable commodities in urbanized areas can make economic sense, especially when coupled with environmental amenities that farming generates for nonfarm people.  At the same time, environmental disamenities of agriculture are larger in densely populated areas.  The political economy outcomes have tended to be favorable to continued farming, albeit with increased regulation....

This simple classroom experiment demonstrates many of the behavioral phenomena associated with the voluntary provision of a public good.  The mechanics of the game are explained in detail and complete instructions are provided, as well as suggestions for follow-up lectures.  Influences such as anonymous voting, persuasion, returns to free-riding, and duration of association can be explored in connection with concepts of incentives, individual rationality, and group welfare.  A number of variations and extensions can be used to incorporate prisoners' dilemmas, incentive compatible mechanisms, negative externalities, and Coasian bargaining.

OUT-OF-STATE EXPORTS OF HARDWOOD MANUFACTURING INDUSTRIES IN THE NORHERN AND CENTRAL APPLALACHIAN STATES
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Bodenman,   John E.; Smith,   Stephen M.; Jones,   Stephen B.
Natural resource-based economic development efforts are becoming increasingly popular.  Interest focuses on industries that export from a state, in order to expand the state and local economic base.  The Northern and Central Appalachian states should be ideally positioned to benefit from forest-based resources, as they have extensive hardwood forests, a favorable growth-to-drain ratio, and easily accessible national and international markets.  This paper examines the export levels of several hardwood product industries and uses tobit analysis to examine establishment and location characteristics related to higher export levels.

A HEDONIC PRICE FUNCTION FOR AUSTRALIAN PREMIUM TABLE WINE
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Oczkowski,   Edward A.
A hedonic price function, relating the price of Australian wine to its attributes, is estimated. Six attribute groups are found to be statistically important in explaining deviations from average wine prices, i.e., quality, cellaring potential, grape variety/style, grape region, grape vintage and producer size. Various interaction terms between these variables and the impact of the year of marketing are also modelled. The consequent marketing implications for producers and consumers are discussed.

Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Sills,   Erin O.; Alwang,   Jeffrey Roger; Driscoll,   Paul J.
The economic impact of migrant farmworkers on an agriculture-dependent region is investigated.  The direct effects of inflows of state and federal dollars for migrant services, and production of high-valued commodities are computed.  Indirect and induced effects are modelled through the use of the IMPLAN input output model.  Various alternatives to migrant labor are investigated, including production of less labor-intensive crops, acreage retirement, and contract H2A workers.  Migrants are found to create substantial economic activity on the Eastern Shore of Virginia.

The future of the Conservation Reserve Program (CRP) will be a pivotal issue in the 1995 farm bill debate. Established under the Food Security Act of 1985, the original objectives of the CRP were to provide a voluntary form of supply control and to reduce soil erosion by retiring highly erodible land on a long-term basis. The latter objective was expanded in 1990 to include retirement of lands for the purpose of protecting water quality.

Intensive double or triple monocropping of rice has caused degradation of the paddy micro environment and reductions in rice yield growth in many irrigated areas in Asia. Problems include increased pest infestation, mining of soil micronutrients, reductions in nutrient-carrying capacity of the soil, build-up of soil toxicity, and salinity and waterlogging. Emerging sustainability problems in intensive rice agriculture show the need for a greater understanding of the physical, biological and ecological consequences of agricultural intensification and greater research attention to long term management of the agricultural resource base.

Weekly customer counts for five supermarkets located in a Southeastern metropolitan area covering 261 weeks are analyzed.  Descriptive statistics indicate that food shopper patterns vary by outlet.  Regression equations are estimated for each location.  Results point to store specific relationships.  They indicate that evaluation of television and radio ads and double couponing can be quite involved.

ESTIMATING THE IMPACT OF CONSERVATION RESERVE PROGRAM CONTRACT EXPIRATION ON CORN AND WHEAT PRICES
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Garrison,   Carl O.; Dicks,   Michael R.; Adam,   Brian D.
The Conservation Reserve Program reduced available cropland in the United States by 34 million acres under the first nine signup periods (1986-1990).  Among these are ten million acres with wheat base and four million acres with corn base, which could potentially produce 288 million bushels of wheat and 340 million bushels of corn per year upon contract expiration.  The impacts of expiring CRP contacts on the production and prices of wheat and corn in the United States are estimated.  Based on past production practices and post-CRP land-use intentions of contract holders, 48.2% of base acres enrolled in CRP will return to production.  Under this scenario, wheat prices will decline by more than 7% and corn prices by more than 2% by 2000, unless ARP levels,...

GEOGRAPHIC INFORMATION SYSTEMS AND APPLIED ECONOMICS: AN INITIAL DISCUSSION OF POTENTIAL APPLICATIONS AND CONTRIBUTIONS
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Taupier,   Richard; Willis,   Cleve E.
Geographic Information Systems (GIS) are becoming increasingly important to virtually all of the natural and social sciences.  Applied economists will find that GIS can make valuable contributions to many of the problems with which they are concerned.  Moreover, a great deal of the science behind GIS technology would benefit from the contributions of applied economists.  This paper presents some initial suggestions for the ways in which GIS may be important to economics and the GIS related issues concerning which applied economists could provide useful insights.

NON-PURCHASING HOUSEHOLDS IN FOOD EXPENDITURE SURVEYS: AN ANALYSIS FOR POTATOES IN SWEDEN
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Andersson,   Mari; Senauer,   Benjamin.
A common problem in food expenditure surveys is that many households report not purchasing some products.  Usually the reason for these zero expenditures is unknown.  The issue may be treated as a potential sample selection bias problem.  This study estimates Engel functions for expenditures for fresh potatoes, processed products, and the value of home-grown potatoes with data from the 1989 Swedish Household Food Expenditure Survey.  The two-step Heckman procedure is used.  A strong generational pattern is found in potato consumption as well as several other significant effects.

SCHOOL CHOICE IN RURAL GEORGIA: AN EMPIRICAL ANALYSIS
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Keeler,   Andrew G.; Kriesel,   Warren.
Previous empirical studies of school choice have been at the national level, or have focussed on northeastern states.  We estimate the demand for private education in rural Georgia, using proportion of private school attendance as an indicator variable.  We find that income, tuition, race and school quality are important choice determinants.  The results provide useful information for rural school administrators, and suggest that a tuition tax credit would have to be substantial to cause a significant exodus from public schools.

Autores: Nayga,   Rodolfo M., Jr.; Capps,   Oral, Jr.
This article examines the impact of socio-demographic factors on individual consumption of alcohol in the United States using the Heckman procedure and logit analysis.  Factors considered are urbanization, race, ethnicity, region, weight, height, sex, food stamp participation, employment status, diet status, day of consumption, household size, age, and income.  All the variables, with the exception of ethnicity and food stamp participation, significantly influence the decision to consume alcohol.  Results also indicate that urbanization, region, sex, food stamp participation, and household size significantly affect the level of alcohol consumption.

WATER MARKETS AND DECENTRALIZED WATER RESOURCES MANAGEMENT
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Easter,   K. William; Hearne,   Robert R.
Because of its importance and the perceived inability of private sector sources to meet water demands, many countries have depended on the public sector to provide water services for their populations.  Yet this has resulted in many inefficient public water projects and in inadequate supplies of good quality and reliable water.  Decentralization of water   management, including the use of water markets, cannot solve all of the water problems, but it can improve the efficiency of water allocation.  When given adequate responsibility and authority, water user associations have effectively taken over water management activities at a savings to tax payers. Moreover, water markets add the potential benefit of improving  water efficiency within the sector as...

In October 1992, the Peace Accord was signed in Mozambique. Many positive changes have taken place since then. and the countryside in postwar Mozambique is in a state of intense transformation. Nevertheless, the government has been largely silent on the issue of land tenure reform, while some of the recommendations regarding land-policy reform that have been proposed are simplistic, uninformed, and fail to reflect the present political reality in Mozambique. This report shows the need to initiate a comprehensive discussion on land policy reform, natural resource management, and decentralized control over resources. The discussion must address fundamental questions about what types of land rights will exist or, more specifically, what types of property...

This paper reports a test of the endowment effect in an economic analysis of localized air pollution.  Regression techniques are used to test the significance of perceived property rights on household WTP for improved air quality versus WTA compensation to forgo an improvement in air quality.  Our experiment contributes to the research into the WTP/WTA divergence by providing a new basis for supporting the existence of an endowment effect.  Our results are in contrast to recent work by Shogren et al. which supports the substitution proposition of Hanemann while rejecting the endowment effect.

ACREAGE RESPONSE UNDER FARM PROGRAMS FOR MAJOR SOUTHEASTERN FIELD CROPS
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Duffy,   Patricia A.; Shalishali,   Kasazi; Kinnucan,   Henry W.
An expected utility model that includes output price and yield uncertainty was used to estimate cotton, corn, and soybean acreage response equations for the Southeast.  The model appeared to fit the soybean and corn data well, resulting in own-price elasticity estimates of 0.317 for corn and 0.727 for soybeans.  When applied to cotton acreage, however, the model did not yield satisfactory results. When elasticity was allowed to change over time, however, statistical results for the cotton equation improved, yielding an own-price elasticity of 0.915 at data means.

Consumer Perceptions of, and Attitudes Toward, Rabbit Meat
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: McLean-Meyinsse,   Patricia E.; Hui,   Jianguo; Meyinsse,   Joseph.
Results from a consumer-oriented study of households in Louisiana and Texas suggest that the nutritional properties of rabbit meat play a minor role in its consumption. In general, users regard rabbit meat as inferior to chicken, beef or pork and non-users are reluctant to try rabbit meat. Based on these results, the market for rabbit meat is likely to remain small, and rabbit production may not be a viable enterprise for farmers in this region of the country.

Do women and minorities earn less due to occupational segregation, lower wages, or fewer hours?
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Lynch,   Lori; Perloff,   Jeffrey M.
Using consistently estimated occupational, wage, and hours equations, we calculate earnings differentials by gender, race, and ethnicity. For example, if the market treated women like men, the average women would have earned $133 more per week so that American women would have earned $338 billion more per year. We decompose the earnings differential into wage, hours, and occupational effects. Occupational segregation explains little of the earnings differential for women, but roughly a fifth of the differential for black and Hispanic men. For all groups, within-occupation wage discrimination is responsible for most of the earnings differential.

A Review of the Socio-Economic Analysis of Soil Degradation Problems for Developed and Developing Countries
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Thampapillai,   Dodo J.; Anderson,   Jock R.
In this paper, the main socio-economic concepts and their applications in the study of soil degradation are reviewed under three broad headings: soil conservation as an input in agricultural production; topsoil as a natural resource somewhere between being renewable and nonrenewable; and the effects of dealing with common property resources. The treatment of soil conservation as an input has involved the demonstration of damage functions and a study of factors influencing the adoption of soil conservation. The study of renewability, or the lack of it, has involved the application of the concept of user costs, whilst the consideration of common property resources has concentrated on the need to minimise the divergences between social and private values.

Technological Change Embodied in Southern NSW and British Wheat Varieties
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Godden,   David P.; Brennan,   John P.
A comparison was made of increases in British and southern NSW wheat yields associated with genetic improvements. Estimates of these improvements were initially compared in each location using two different techniques. These techniques were a "variety improvement index" and a "vintage yield function". Yield increases "due to" genetic improvements were then compared between countries using both techniques. The variety improvement index technique suggested that there was little overall difference between genetic improvement in wheat in Britain and southern NSW. The vintage yield function technique suggested that the rate of yield increase for all varieties "due to" genetic improvement was markedly inferior in southern NSW. Estimated genetic improvement in...

Quantity Surcharges on Groceries
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Agrawal,   Jagdish; Grimm,   Pamela E.; Srinivasan,   Narasimhan.
A quantity surcharge exists when the unit cost of a given brand is higher for a large-size package than for a smaller one.  This paper examines some product and household characteristics that influence observed quantity surcharging practices.  Results indicate that the propensity to buy a large-size package of a product is positively influenced by the extent of a household's usage of that product, procurement cost, and carrying capacity, and is negatively influenced by the propensity to price search.  A retailer's decision to levy a quantity surcharge is, in turn, influenced by the demand for the product, the propensity to buy large-size packages, and to some extent the product's carrying cost.

INTERVENTIONS AND PRODUCTION SECTOR WASTE IN LDC AGRICULTURE
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Fulginiti,   Lilyan E.; Perrin,   Richard K.
Recent studies have revealed that less developed countries (LDCs) have been taxing their agricultural sectors at rates of 40-50%.  This study uses quantity-based general equilibrium measures of deadweight loss to evaluate the cost of these distortions in 18 of these countries.  The Allais-Debreu loss measures indicate that from 7-16% of either output or of the agricultural resource base has been wasted due to the associated misallocation of agricultural inputs across these countries.

Cotton and synthetic fiber competition in textile mills between 1961-1990 was examined using a time-varying parameter regression model.  Results indicate that the structure of demand for cotton is not stable and cotton's share responses to changes in the prices of cotton and synthetic fiber vary over time.  Cotton and synthetic fiber competition in textile mill use is essentially between cotton and noncellulosic fiber.  Cellulosic fiver is not a cotton competitor.

DIFFERENCES IN CONSUMERS OF FRESH TOMATOES AT FOUR RETAIL VENUES
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Brumfield,   Robin G.
This paper presents the results of surveys of fresh tomato consumers conducted in 1990 in four New Jersey produce venues: a supermarket, a farmers' market, an at-the-farm store, and two roadside stands.  The surveys were conducted through face-to-face interviews.  Consumers' preferences, purchasing patterns, attitudes and demographics were examined.  Results of the surveys suggest that supermarkets should emphasize price and convenience in marketing fresh tomatoes; whereas farmers' markets, at-the-farm stores, and roadside stands should emphasize taste and freshness.

Contact for this paper: Laura Bipes/University of Minnesota/Department of Applied Economics/ 1994 Buford Avenue./ St. Paul, MN 55108 USA.  From the start, agriculture played a central role in the Uruguay Round of GATT trade negotiations.  The Punta del Este Declaration called for a solution to the problems facing agricultural trade through modified trade rules and an agreement to lower protection levels.  It was recognized that such an improvement implied negotiations on the national farm policies as well as just trade policies.  The time that it took to reach agreement reflected the political sensitivity and technical complexity of this task.   The Agreement embodied in the Final Act of the Uruguay Round breaks new ground for agriculture, and takes a big...

PRICE-CONDITIONAL TECHNOLOGY
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Fulginiti,   Lilyan E.
Economics theorists for years have considered the possibility that the direction of technical change is altered by changes in relative prices.  Prices also have been identified as one of the determinants of technical change through innovation.  This article extends the theory of the firm to cover situations in which the firm’s' technology set is conditional on expected prices.  The basic idea is to distinguish between “"market prices,"” or the prices that guide the firm’s choices subject to the technology that is in place, and “"normal prices,"” the prices conditioning the choice of technology.  A “"generalized”" price effect is obtained that included the traditional price effect as well as the technical change effect of price changes, and an example is...

Adoption of Hybrid maize in Zambia: effects on gender roles, food consumption, and nutrition
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Kumar,   Shubh K.
Enhanced agriculture productivity in sub-Saharan Africa is critical to promote economic growth and poverty alleviation and to avoid increasing food scarcities in the region. The impact of commercialization and intensification of agriculture on the well- being of the rural poor depends on how they are carried out. Past research by IFPRI and collaborating institutions on commercialization of small- scale farming in about a dozen countries provided new knowledge about the relationships between commercialization and rural well- being as measured by incomes, consumption, and nutrition. These links were shown to depend greatly on household behavior, which in turn is influenced by intrahousehold processes. A better understanding of these processes is likely to...

GOVERNMENT VERSUS PRIVATE QUALITY ASSURANCE FOR AUSTRALIAN FOOD EXPORTS
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Wills,   Ian R.; Harris,   Jane.
Most foodstuffs have quality attributes that are difficult to determine prior to purchase. Thus quality assurance is an inherent problem in food exporting. Private quality assurance can succeed if exporters can credibly signal that they have much to lose from cessation of purchases. If exporters do not provide credible quality signals, and foreign importers judge food quality according to country of origin, honest exporters can suffer negative spillovers from others' cheating under either government or private quality assurance. For both economic and political reasons, the best choice between government and private quality assurance will differ between foods and importing countries.

Various events have led to the development of highly complex cooperative operations and to concepts for understanding operations. However. development of membership structures and concepts for understanding these structures has lagged. This paper imports organizational design and contingency theory into the member control literature. Membership structure is understood as organization-like, producing a service (Le., member control). Member control structure is understood as having three aspects (representation, policy making, and oversight) and two environments (the members themselves, and management and operations). Building from cooperative principles and following the development of cooperatives from simple to complex organizations, this paper develops a...

WHEN FLEXIBLE FORMS ARE ASKED TO FLEX TOO MUCH
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Driscoll,   Paul J.
Taylor series-based flexible forms cannot be interpreted as Taylor series approximations unless all data used in estimation lie in a region of convergence.  When flexible forms lose their Taylor series interpretation, elasticity estimates will be biased.  When the flexible form is a translog, Rotterdam, or AIDS model, the region of convergence is shown to be the entire positive orthant.  Regions of convergence associated with quadratic, Leontief, and any flexible form that does not employ logged arguments are smaller and may not encompass the entire data set.  Implications for production and demand analyses and experimental design are discussed.

Autores: Lambert,   David K.
Nonparametric procedures are used to compare technological change in SIC 2011, meatpacking, and SIC 2015, poultry slaughter and processing.  There has been a greater increase in total factor productivity in poultry than in the red meats.  Evidence also suggests recent differences in the bias of this technological change, with production changes being labor using in poultry and biased towards greater efficiency in the use of live animal inputs in meatpacking.

FEEDFORWARD NEURAL NETWORK ESTIMATION OF A CROP YIELD RESPONSE FUNCTION
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Joerding,   Wayne H.; Li,   Ying; Young,   Douglas L.
Feedforward networks have powerful approximation capabilities without the "explosion of parameters" problem faced by Fourier and polynomial expansions.  This paper first introduces feedforward networks and describes their approximation capabilities, then we address several practical issues faced by applications of feedforward networks.  First, we demonstrate networks can provide a reasonable estimate of a Bermudagrass hay fertilizer response function with the relatively sparse data often available from experiments.  Second, we demonstrate that the estimated network with a practical number of hidden units provides reasonable flexibility.  Third, we show how one can constrain feedforward networks to satisfy a priori information without losing their flexible...

QUALITY PREMIUMS FOR AUSTRALIAN WHEAT IN THE GROWING ASIAN MARKETS
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Ahmadi-Esfahani,   Fredoun Z.; Stanmore,   Roland G.
An hedonic price function is applied to Australia's wheat exports to the growing Asian markets. The values for the quality characteristics in the wheat markets of Indonesia, Malaysia, Singapore, South Korea, and Thailand are estimated. The data base for the study is from the Australian Wheat Board shipments over the period 1984 to 1991. The sample is divided into two separate time periods to test the consistency in demand for export wheat and to trace recent trends in quality premiums. The implications of the results for wheat marketing and trade are explored.

We assess the nonmarket value for retention of farmland in the Moncton area of New Brunswick.  We examine a number of factors explaining household external values for farmland preservation and expand on previous work by Beasley et al., Bergstrom et al., and Halstead.  Our findings indicate that the marginal external benefit of preserving farmland in general in this region is small compared to the market price and that spatial embedding is not automatic in contingent valuation studies.

REPORTING RESPONSE RATES FOR TELEPHONE SURVEYS USED IN AGRICULTURAL ECONOMICS RESEARCH
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Gripp,   Sharon I.; Luloff,   A.E.; Yonkers,   Robert D.
Response rates are one indicator of a survey's data quality, as a great deal of importance has been placed on the mail survey's response rate.  However, a telephone survey's response rate usually is not reported.  Even if one is reported, the numbers used in the calculation are rarely defined making the response rate interpretation unclear.  Using a recent telephone survey of Pennsylvania dairy managers, this paper demonstrates how telephone survey data should be reported.  Essentially, every research report should include a discussion of how the survey was conducted, a disposition table, and well-defined formulas used to calculate response rates.

Comparison of Two Angler Data Collection Methods In North Dakota
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Baltezore,   James F.; Leitch,   Jay A.; Vachal,   Shawn R.
North Dakota's recreational fishing industry is an important part of the state's economic base. Resident and nonresident anglers spent nearly $260 million dollars on fishing-related activities in the state in 1990 (Baltezore and Leitch 1992). Management of a resource that generates this amount of economic activity requires accurate and periodic information. Management uses information in at least two ways. Information is initially used to make a decision. Once a decision is made, additional information is collected to assess the results or outcomes of that decision. In effect, information is used to make a decision and monitor changes resulting from that decision (Kerestes and Leitch 1983). Periodic information is needed to monitor the outcomes of...

Economic Analysis of the Impact of Paratuberculosis on the Kentucky Cattle Industry
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Meyer,   A. Lee; Hall,   Harry H.
Paratuberculosis (Johne's disease) is endemic in the U.S. and Kentucky cattle industry, affecting both beef and dairy cattle. The disease affects the productivity of cattle ( lowering milk production, reducing the weights of calves) and eventually causes the death of infected animals. The disease spreads among cattle on farms, primarily through fecal shedding of the organism, and may be brought onto a farm through the purchase of infected animals. Since the disease often has long incubation and subclinical stages, testing may be necessary to confirm its presence. From late 1993 into early 1994, a random sample of blood samples drawn for brucellosis testing was also examined for paratuberculosis. This analysis indicated that less than one percent of...

SEQUENCING CAPITAL AND LAND MARKET REFORMS FOR BROADLY BASED GROWTH
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Carter,   Michael R.
After developing a conceptual apparatus, this paper econometrically explores the basis and bias of agrarian growth in contemporary Paraguay, a country where increasing land scarcity and rural unrest have occurred in the midst of rapid export growth. By taking apart the microeconomics of the growth boom, the goal is not only to uncover what is happening, but to identify policy options which might modify the outcome. The paper's chief finding is that more broadly based or inclusionary growth not only requires a microeconomic activism which reaches beyond the broad dictates of liberalization, but also attention to the specific temporal sequencing or ordering of these sectoral policies.

Land Tenure, Agrarian Structure, and Comparative Land Use Efficiency in Zimbabwe: Options for Land Tenure Reform and Land Redistribution
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Roth,   Michael J.; Bruce,   John W.
Zimbabwe reached a crucial crossroads in its land reform with the expiration of the Lancaster House Constitution in April 1990, which opened the door for policy debate on alternative land-redistribution options. Proponents of the land reform have aggressively called for an expansion of the resettlement program to help redress the unequal distribution of land resources and to rectify acute land scarcity in communal areas. Opponents of rapid and substantial land reform have emphasized the superior efficiency of the commercial farming sector and the adverse consequences that a substantially expanded resettlement sector would have on agricultural output and the balance of trade. Many key questions lie at the heart of the land policy debate. First, what tenure...

Rooting stimulation in muscadine grape cuttings
Provedor de dados: Scientia Agricola
Autores: Castro,P.R.C.; Melotto,E.; Soares,F.C.; Passos,I.R.S.; Pommer,C.V.
The muscadine grape (Vitis rotundifolia Michx.) is native to Florida and has been cultivated for many years in U.S.A. It is harvested as single berries instead of in bunches and has small leaves. The fruit skin is thicker than those of bunch-type grapes. One reason for its popularity is that the muscadine is seldom seriously affected by diseases or insects. The muscadine grape is not readily propagated by hardwood cuttings, therefore the present work was carried out to develop a method for commercial propagation of its cuttings, using treatments with growth regulators (auxins) and low temperature. The results showed that the rooting of both basal and middle shoots of muscadine grape is better than the rooting of terminal sections of the shoots. Cuttings...

Study on vinasse dynamics in soil usin energy dispersive X-ray fluorescence with radioisotopic excitation
Provedor de dados: Scientia Agricola
Autores: Simabuco,S.M.; Nascimento Filho,V.F.
The distribution of S, Cl, K and Ca along the profiles of two soils of different texture (Red Yellow Podzolic and Dark Red Latosol) treated with amounts of vinasse equivalent to 4000 m³/ha were studied using energy dispersive X-ray fluorescence, observing a significant increase in the contents of these elements. The same effect was observed for Cu, Zn, Rb and Sr contents in soils treated with vinasse as compared to the control. The concentrations of Al, Si, Ti, Mn, Fe and Zr could also be evaluated but no significant variation was observed due to the high soil initial concentrations of these elements as compared to the low concentrations in the vinasse. Annular radioactive sources of Fe-55 and Cd-109 were employed for the excitation of these elements in...

Provedor de dados: Scientia Agricola
Autores: Villagra,M. M.; Michiels,P.; Hartmann,R.; Bacchi,O.O.S.; Reichardt,K.
Experimentally determined values of unsaturated soil hydraulic conductivity are presented for an Alfisol of the county of Piracicaba, S.P., Brazil. Simultaneous measurements of soil water content and pressure head are made along a 125 m transect within an irrigated field during the internal drainage process. Calculations of the soil hydraulic conductivity were made using the instantaneous profile method (Watson, 1966) and the unit gradient method (LIBARDI et al., 1980). The spatial variability of the soil hydraulic conductivity manifested along the transect indicates the need to develop a field method to measure K(theta) within prescribed fiducial limits, taking into account quantitative evaluation of spatial and temporal variances associated with the...

Discutiram-se os critérios de avaliação de materiais orgânicos empregados como fertilizantes adotados na legislação brasileira atual. Trabalhando com amostras de compostos, estéreos, resíduos industriais e turfa, discutiu-se a determinação de carbono orgânico através de oxidação pelo íon dicromato. Sugeriu-se que o atual método de determinação de matéria orgânica total por combustão tenha sua utilização restrita ou desaconselhada, devido aos erros grosseiros que proporciona. Como forma de se avaliar a qualidade de materiais orgânicos, discutiu-se a determinação da capacidade de retenção de cátions (CTC) em fertilizantes e materiais orgânicos em geral. O grau de maturação ou estabilidade de compostos orgânicos pôde ser convenientemente expresso através da...

Autores: Nogueira,S.S.S.; Nagai,V.; Braga,N.R.; Novo,M. Do C.S.S.; Camargo,M.B.P.
An experiment to study the growing pattern of a chickpea variety, IAC-Marrocos, was carried out at the Monte Alegre Experimental Station, SP, during 1987 and 1988. The dry matter production of all parts of the plant, as well the leaf area index, were weekly evaluated. Exponential quadratic models of regression were adjusted to total dry matter, leaf dry matter and leaf area index, and a linear model to dry matter of grain. Based on the growth analysis it was concluded that the chickpea is a rustic eatable plant that can be recommended as an alternative winter crop for similar climatic conditions as those of the experiment.

Concluiu-se que a expressão proposta deve ser utilizada para determinação da lâmina média ponderada por estar conceitualmente mais correta, apesar de na prática os valores calculados pela metodologia proposta serem muito próximos daqueles obtidos pelo cálculo tradicional.

Competition effects with mixed stands of wheat and kochia (Kochia scoparia) biotypes resistant and susceptible to acetolactase synthase inhibitor herbicides
Provedor de dados: Scientia Agricola
Autores: Christoffoleti,P.J.; Westra,P.
Greenhouse experiments were conducted to compare the competitive ability of sulfonylurea resistant and susceptible kochia (Kochia scoparia L. Schard) compared to wheat. The results of several replacement series experiments indicate that wheat was the dominant competitor, and an average of one wheat plant reduced resistant kochia yield per plant equal to the effect of 4.8 resistant kochia or 5.4 susceptible kochia plants. Intraspeciflc competition was more important than interspecific competition for wheat, whereas the reverse was true for the resistant and susceptible kochia. The results of the niche differentiation index (NDI) indicate that wheat and either resistant or susceptible kochia are only partly limited by the same resources. The resistant and...

Autores: Silva,W.R. da; Chamma,H.M.C.P.; Novembre,A.D. da L.C.; Moraes,M.H.D. de.
Objetivando verificar a interferência da excisão de partes da semente de milho no desempenho biológico, a pesquisa foi conduzida a partir de tratamentos representados por remoções aproximadas de 0, 14, 28 e 37%, em peso, sem que o embrião fosse diretamente afetado. A avaliação, conduzida em laboratório (germinação e vigor) e em campo (emergência e produção), permitiu as seguintes conclusões: - Há a possibilidade biológica de excisar parte (±14% em peso) da semente de milho, em pré-semeadura e com tratamento fungicida, em lotes de alta qualidade fisiológica a serem utilizados em regiões favoráveis ao desenvolvimento da espécie; a retirada de partes da semente de milho contribui para a redução do seu potencial de conservação.

Provedor de dados: Scientia Agricola
Autores: Marques,P.V.
Analisaram-se indicadores de concentração no mercado de abate de frango de corte inspecionado no Estado de São Paulo desde 1978 até 1989. Os índices de concentração de Hirschman-Herfíndahl (H) e os índices de concentração de Gini (G) mostraram tendência estatística de se elevarem com o passar do tempo. O índice de concentração dos quatro maiores frigoríficos (C4) não apresentou tendência estatística para se elevar, enquanto que o índice de concentração das oito e das dezesseis maiores empresas (C8 e C16, respectivamente) mostraram tendência para se elevar a partir de 1980. Concluiu-se que a concentração do mercado de abate e processamento de frangos manteve-se mais ou menos estável com leve tendência a aumentar dos oito menores frigoríficos para baixo....

The effect of feed supplementation on the onset of puberty in Brazilian dairy heifers
Provedor de dados: Scientia Agricola
Autores: Meirelles,C.F.; Abdalla,A.L.; Vitti,D.M.S.S.
Most Brazilian dairy production is conducted by small holders whose general management skills and feeding programs are often deficient. One common problem directly attributed to underfeeding is that heifers rarely reach sexual maturity before 15 months of age. Groups of growing heifers were treated to detect the effects of protein supplementation and antihelmintic treatment on sexual maturity. The first ovulation occurred at 513 ± 44 and 573 ± 36 days (P&lt;.01) in supplemented and control groups, respectively. Liveweight gains from start of the trial to the first ovulation were 378 ±.02 and 331 ±.04 g for suplemented (S) and control (C) groups. Only 52.17 % of heifers in C group (11 of 23) but 95.65 % in S group (22 of 23) reached sexual maturity before...

Umidade relativa de equilibrio e oxidação de lipídeos em farinhas de castanha do Pará, de macadâmia e de soja
Provedor de dados: Scientia Agricola
Autores: Prado-Filho,L.G. do.
Foi estudada a oxidação de lipídeos adicionados a farinhas de castanha do Pará (Bertholleta excelsa), de macadâmia (Macadâmia integrifolia) e de soja (Glycine max) equilibradas nas atividades de água (Aa) 0,51; 0,57; 0,67; 0,75; 0,79 e 0,81, a 35°C. O substrato utilizado para quantificar tanto a oxidação autocatalítica como a oxidação enzímica foi o óleo de soja na proporção de 20% (p:p). Dois mecanismos de oxidação de lipídeos concorrem pelo substrato nas condições estudadas. A baixos valores de Aa - de 0,51 a 0,75 - o mecanismo mais eficiente é a autoxidação devida à maior exposição do substrato ao oxigênio e à menor mobilidade dos reagentes - enzima e lipídeo - nas reações de natureza enzímica. Em valores de Aa maiores - 0,79 e 0,81 - predomina a...

Autores: Bassoi,L.H.; Fante Júnior,L.; Jorge,L.A.C.; Crestana,S.; Reichardt,K.
A distribuição do sistema radicular do milho irrigado, até 1 m de profundidade, em uma terra roxa estruturada latossólica em Piracicaba, SP, foi analisada aos 126 dias após a emergência das plantas. As raízes expostas pela abertura de trincheiras longitudinalmente às Unhas de plantas foram filmadas e essas imagens digitalizadas e processadas para a contabilização de sua distribuição no perfil do solo, por meio do sistema SIARCS desenvolvido para esse fim. A densidade de raiz de milho a 0-60 cm foi maior para a aplicação de N via solo, enquanto que a 60-100 cm a fertirrigação proporcionou uma maior presença de raízes. Por meio de tensiômetros e da sonda de nêutrons, notou-se, respectivamente, que a maior amplitude de variação do potencial matricial da água...

Autores: Pacheco,F.B.P.; Reichardt,K.; Tuon,R.L.; Bacchi,O.O.S.; Villagra,M.M.
As variabilidades de medidas de potencial mátrico da água no solo e de gradiente de potencial hidráulico são analisadas utilizando conceitos geoestatísticos e estatística da distribuição normal. São analisados 25 pares de dados, coletados ao longo de uma transecção de terra roxa estruturada, de 125 m de comprimento. Autocorrelogramas e semivariogramas não indicaram dependência espacial nas variáveis estudadas. A variabilidade do potencial mátrico da água no solo, medida através de tensiômetros, é menor do que a variabilidade do gradiente de potencial hidráulico. Este último apresentou alta variabilidade, a ponto de comprometer seu uso em estimativas de fluxos de água no solo.

Objetivando verificar a influência do teor de água do substrato no enraizamento de estacas de eválvulo branco (Evolvulus pusilus), conduziu-se um ensaio sob condições de laboratório. Os efeitos de cinco níveis de água no substrato (solo x areia 3:1 de 20, 40, 60, 80 e 100% da capacidade de retenção) no enraizamento, foram avaliados através da porcentagem de estacas enraizadas. Para cada repetição, 20 estacas apicais, com comprimento médio de 15 cm, foram introduzidas a uma profundidade de 6 cm, perfazendo 80 estacas por tratamento. Os resultados permitiram concluir que o teor de água do substrato entre 50% e 70% da capacidade de retenção, possibilitou enraizamento superior para estacas de eválvulo branco.

Autores: Villagra,M.M.; Gabriels,D.; Verplancke,H.; Hartmann,R.; Reichardt,K.
Soil water balance components were measured during two periods (from 1989 to 1991) on a Dark Red Latosol (oxisol) in Piracicaba,SP, Brazil. The change in soil water storage and the soil water fluxes at the lower limit of the rooting zone were calculated for a transect of 25 observation plots. Hydraulic head gradients were determined by tensiometer measurements. Soil water flux densities were estimated through Darcy's equation. The actual evapotranspiration of the crops and weeds and the actual evaporation of bare soil were obtained from the water balance equation and this for two periods under different crop rotations. For the first period the sequence was bare soil-corn-weeds and for the second period it was stubble mulch-weeds-corn. For assessing the...

Avaliou-se, em fins do verão de 1993, o grau de incidência da ferrugem (Tranzschelia discolor f. sp. domesticae), em dezoito seleções IAC de pessegueiro e seis de nectarineira, mantidos em lote de germoplasma na Estação Experimental de Jundiaí (23°08'S; 46°55'W). A porcentagem de incidência do patógeno foi estimada através de observações macroscópicas das folhas, atribuindo-se notas de 1 a 5 (1 = nula, 2 = leve, 3 = moderada, 4 = severa, 5 = muito severa), conforme o grau da severidade do sintoma. Todo o material pesquisado mostrou-se suceptível ao patógeno, entretanto, as seleções apresentaram sensíveis variações em graus de susceptibilidade. As seleções com maior tolerância ao patógeno foram: 1) pêssegos 'Régis' e IAC 4685-45 e 2) nectarinas 'Josefina' e...

Mineralogia e mobilidade de cations de uma alteração intempérica de diabásio
Provedor de dados: Scientia Agricola
Autores: Clemente,C.A.; Marconi,A.
Em uma seqüência de alteração intempérica de diabásio, situada no município de Capivari, SP, foram estudadas a mobilidade de cátions liberados no processo e a evolução mineralógica ocorrida. A seqüência situa-se em condições de clima sub-tropical semi-úmido e de boa drenagem. A mineralogia do diabásio, constituída essencialmente de plagioclásios e piroxênios, evoluiu para uma mineralogia simples, onde na fração argila do solo ocorre apenas a caulinita, associada a óxidos de ferro, que não foram determinados. Vermiculita ocorre nas fases intermediárias, como o único argilomineral 2:1. A lixiviação de cátions solúveis ocorre já nos primeiros estágios do processo, seguidos da sílica, também com remoção rápida, mas que, em face de seu elevado teor na rocha de...

Condições de conservação pós-colheita de frutos de pimentão (Capsicum annum L.)
Provedor de dados: Scientia Agricola
Autores: Barros,J.C. da S.M. de; Goes,Á. de; Minam,K.
Com o objetivo de verificar a conservação de frutos de pimentão, foi estudada a utilização de dois tipos de embalagem e um seqüestrador de etileno, em condições ambientais e em geladeira. As avaliações foram realizadas a cada cinco dias, obtendo-se as seguintes conclusões: a melhor temperatura para conservação de pimentões situa-se entre 7 e 9°C; o armazenamento de pimentões em bandejas envolvidas com filme de PVC, constitui-se na melhor alternativa para sua conservação, naquela faixa de temperatura. O permanganato de potássio, colocado em cápsulas perfuradas no interior das embalagens, não apresentou efeito evidente como absorvente de etileno. Após 30 dias, foram verificadas perdas de frutos por senescência e/ou pela incidência de doenças.

Soybeans IAC-8 were harvested in the growth stages R7 and R8 commercial harvesting time and at two other subsequent times to compare their physiological and technological characteristics. Seeds were stored at two moisture levels, 12% and 15%, for 6 months. Germination and vigor (acelerated aging, electrical conductivity), oil and free fatty acids, peroxide and iodine values were evaluated periodically. As expected, the time of harvesting and seed moisture content affected seed performance, while oil content did not correlate to physiological quality as did acidity, peroxide value and iodine number.

Arroz e feijão foram cultivados em soluções nutritivas em presença de três níveis de N, P e K. O método da bioavaliação do estado nutricional em que raízes destacadas absorvem elementos marcados, no caso presente 15N e 32P, foi comparado com o de diagnose foliar. Foram tiradas duas conclusões principais: 1) os bioensaios mostraram ser um procedimento rápido e útil para o diagnóstico do estado nutricional das duas espécies, visto haver correlação significativa negativa entre absorção e produção de matéria seca; 2) a absorção de dois isótopos pelas raízes da planta previamente submetida a níveis diferentes de N e de P na solução foi inversamente proporcional aos teores foliares desses elementos.

Autores: Setubal,J. W.; Zanin,A.C.W.; Nakagawa,J.
A ocorrência de sementes duras em quiabeiro (Abelmoschus esculentus (L.) Moench) foi estudada em função da colheita única dos frutos na senescência das plantas ou da colheita periódica dos frutos no estádio de maturação morfológica. As cultivares utilizadas foram "Amarelinho", "Santa Cruz-47" e "Campinas-2 IAC 4076" e os frutos foram separados em aqueles provenientes da haste principal e os oriundos dos ramos laterais. A porcentagem de sementes duras foi avaliada por meio do teste padrão de germinação e os dados obtidos permitiram verificar que o método de colheita única aumentou a ocorrência de sementes duras e, pelo fato de "Amarelinho" não apresentar essa característica, esse método pode ser utilizado para a mesma, com redução nos custos de produção de...

Provedor de dados: Scientia Agricola
Autores: Hernandez,F.B.T.; Modesto,J.C.; Suzuki,M.A.; Corrêa,L.S.; Reichardt,K.
In order to evaluate qualitative and nutritional aspects of fig-trees with respect to six irrigation and six nitrogen levels, at Ilha Solteira, SP, Brazil, an experiment was carried out in randomized blocks, with subdivided plots, and four replications. Results showed that in four dates during harvest, only the first analysis (January 2, 1991) showed influence of nitrogen fertilization on fruit soluble solids (brix). There was no significant effect of treatments on pulp/peel relation for the four harvestings. In relation to leaf macronutrient concentration at flowering, water supply influenced N, P and Ca concentrations, and nitrogen influenced only Ca concentration. For an average of 10 t.ha-1 of mature fruit and 1.3 t.ha-1 of immature fruit production,...

Provedor de dados: Scientia Agricola
Autores: Fonseca,H.; Gallo,C.R.; Calori-Domingues,M.A.; Gloria,E.M.; Approbatto,P.J.; Fonseca,E.L.; Zambello,I.V.
The present experiment aimed to evaluate the effect of sodium ortho-phenylphenate (SOP) application to in-shell moist peanuts for the control of aflatoxin production. Previous studies showed the need to improve the SOP solution distribution on peanut pods to evaluate the product. Thus, in this experiment the place of the spray system was the bag filler pipe of the pre-cleaning machine in the warehouse. In the 1989 rainy season two lots of 120 bags of in-shell moist peanuts were sprayed with 0.5 and 1% SOP solutions and aflatoxin production was not controlled. In the dry season of 1989 and in the rainy season of 1990, in-shell moist peanuts were sprayed with 5% SOP solution. The coverage of pods with the solution was efficient, allowing a uniform...

Regime alimentar de Schizodon intermedius Garavello &amp;amp; Britski do rio Tibagi, Paraná, e sua relação com algumas características morfológicas do trato digestivo (Osteichthyes, Anostomidae)
Provedor de dados: Zoologia
Autores: Yabe,Regina de Souza; Bennemann,Sirlei Terezinha.
In order to analyse the diet of Schizodon intermedius Garavello &amp;amp; Britski, 1990, captures were made every season during the period of April/1990 to February/1991, using gillnets of different mesh size at Sertanópolis, a region of Paraná State. An analysis of stomach fullness degree was made upon 76 individuals (including young ones). A sample of 20 adult specimens was chose to compare the morphology of the digestive tract with the diet found. It was concluded that S. intermedius is a grazer herbivore whose principal diet consists of leaves and stalks of two monocotyledonous plants: Poaceae and/or Cyperaceae. This species shows quanlitative, but not qualitative feeding seasonal variations. It was verified that intestinal quotient of the species is X...

Bottom-nets as a new method for quantitatively sampling tadpole populations (Amphibia, Anura)
Provedor de dados: Zoologia
Autores: Gascon,Claude.
A new technique to reliably estimate true tadpole abundance in small ephemeral forest ponds based on a sample taken from a bottom net is presented. The bottom net is placed in the pond before it fills with water. At given intervals the bottom net is lifted through the water column and all tadpoles can be counted. Based on a series of calibrations, the technique showed significant correlations between estimated abundance of Osteocephalus taurinus Steindachner, 1862, Colostelhus marchesianus Melin, 1941, Phyllomedusa tomoptema Cope, 1868, and aeshnid larvae, and true abundances based on total counts.

Attrativeness of differents baits (fish, faeces and banana) upon ovarian development fases of Calliphoridae and Sarcophagidae was evaluated. The insects were captured in Distrito Federal (urban area) and Rio de Janeiro city (beach, zoological garden, urban area and Tijuca forest). The most frequent species captured were: Calliphoridae - Chrysomya megacephala (Fabricius, 1794) 78,9% and Chtysomya puloria (Wiedemann, 1818) 5,4% - and Sarcophagidae - Sarcophagula Wulp, 1887 2,3% and Peckya chrysostoma (Wiedemann. 1830) 2,2%. Fish was more attractive to females of Calliphoridae flies in intense ovarian vitelogenesis, although banana atracted more flies with mature eggs. Faeces and fish were more atractive for Sarcophagidae in the beggining of vitelogenesis.

Skin to lung migration of Schistosoma mansoni Sambon, 1907 - (75 Se) - selenomethionine-labeled cercariae was tracked by tissue autoradiography on days 1, 4, 6, 8 after challenge, in rabbits immunized with a S. mansoni derived saline extract. Either in vaccinated animals or in those of the control unprimed group, the peak of skin schistosomula occurs 24hs after infection. Comparison between peaks of lungs migrating larvae showed that, in control animals, the increase of worm burden in this site, is detected on the 6th day post-infection, differing from immunized rabbits, in which this peak occurs on day 4, when skin and lungs counts are still equivalent, decreasing gradually, showing a different pattern of the S. mansoni migration and suggesting that main...

Autores: Chaves,Paulo de Tarso da C.
At Guaraluba bay, the catfish Genidens genidens shows incubating behavior during the summer months. The larvae are either less or heavier than the eggs, and their stomach analysis confirms the exogenous leeding during incubation. Embryos sizes can increase to 59mm in total lenght and 2,8g in total weight, including the yolksac. It was observed that the largest larvae are guarded by the largest adults, and that the embryo size is similar among individuals from the same adult.

Qualilative and quantitative studies of Isopoda species were made at Mundaú/Manguaba Estuary-Lagoon Complex on the Coast of Alagoas State. Six points were established in order to carry out methodical collections of animals. These collections were made monthly, without interruption, from April, 1990 to March, 1991, in which three families, five genera and seven species of Isopoda were identified. A special key for identification of Isopoda and also diagnosis for each species are presented. Sphaeromatidae Family was the most significant and Cassidinidea fluminensis (Mane-Garzón, 1944), was the species with numerical dominance. Space/time distribution of the species of Isopoda was related to the variation of salinity.

A modelização matemática das trocas de massa e de energia resultantes da interação entre vegetação e atmosfera é tratada pela combinação de análises das equações diferenciais representando a conservação de propriedades do ar (temperatura e umidade) com a equação do balanço de energia local do meio vegetal. Fluxos e fontes de calor e de massa, perfis de temperatura e umidade foram calculados através das relações matriciais das equações diferenciais discretizadas. As transferências radiativas são definidas no modelo, considerando a vegetação como um meio túrbido, onde as superfícies vegetais são distribuídas de forma aleatória no espaço. Os resultados produzidos pelo modelo para floresta são comparados com medidas micrometeorológicas realizadas na Reserva...

CONSERVAÇÃO Ex Situ DE RECURSOS GENÉTICOS DE PLANTAS NA REGIÃO TROPICAL ÚMIDA
Provedor de dados: Acta Amazonica
Autores: PAIVA,João Rodrigues de.
Nas duas últimas décadas, a Amazônia tornou-se foco de um processo de ocupação acelerado e desordenado, criando sérias preocupações quanto ao futuro de seu vasto patrimônio genético. A situação tende a se agravar à medida em que os métodos de conservação dos recursos genéticos, que ora são utilizados na Amazônia para manter coleções de plantas em campo, revelam-se inapropriados. Além de onerosos e limitados à espécies de reconhecido valor econômico. Resultados de pesquisa evidenciam a importância de diversidade de espécies, densidade de plantas e variabilidade genética, como estratégias utilizadas pelas plantas para sobreviverem à heterogeneidade do ambiente tropical. Tomando-se como referência essas características, propõe-se discutir e apresentar um...

Estudou-se o comportamento alimentar de morcegos e o seu papel na dispersão de sementes de Vismia cayennensis na região de Manaus, Amazonas. As características da planta e dos frutos correspondem à síndrome de quiropterocoria. Cinco espécies de morcegos filostomídeos se alimentaram dos frutos: Sturnira lilium, Sturnira tildae, Artibeus concolor, Carollia perspicillata e Rhinophylla pumilio. Aparentemente, há uma relação entre o comportamento de forrageamento em grupos e a maior disponibilidade de frutos na primeira parte da noite. O comportamento alimentar foi semelhante para todas as espécies de morcegos, variando em função do modo de apresentação dos frutos. Os testes de germinação e os padrões de distribuição das plantas indicam que morcegos são os...

Amido no megagametófito de Araucaria angustifolia (Bert.) O. Ktze: degradação durante a germinação e desenvolvimento do esporófito
Provedor de dados: Acta Botanica Brasilica
Autores: Rosado,Rosa Maris; Ferreira,Alfredo Gui; Mariath,Jorge Ernesto de Araujo; Cocucci,Alfredo Elio.
O pinheiro brasileiro possui um diásporo de grandes dimensões, o pinhão, rico em reservas amiláceas. A mobilização dessas reservas pelo embrião foi quantificada em secções transversais do megagametófito, em cinco estágios de desenvolvimento da plântula, sob dois tratamentos, na luz e no escuro. Na luz, o consumo das reservas do megagametófito pela plântula é mais rápido do que no escuro e, existe uma tendência ao consumo do amido realizar-se primeiro na região do megagametófito próxima ao embrião.

Predação de sementes de leguminosas por bruquídeos (Insecta: Coleoptera) na Serra dos Carajás, Pará, Brasil
Provedor de dados: Acta Botanica Brasilica
Autores: Lomônaco,Cecília.
Estudou-se a predação de sementes em Bauhinia pulchella Benth. (Caesalpiniaceae), Mimosa acutistipula Benth. var. nigra Hub., Mimosa somnians H.B. ex Willd. (Mimosaceae) e Phaseolus linearis H.B.K. (Fabaceae) para investigar a taxa de predação e a existência de defesas contra a ação de predadores. Foi constatada a preferência por sementes de maior tamanho pelo bruquídeo de Bauhinia pulchella, o que pode significar uma adaptação das plantas em ter sementes pequenas que escapem da predação. Em Mimosa somnians, a imprevisibilidade do número de sementes viáveis produzidas poderia consistir num mecanismo de defesa, por impedir a otimização da quantidade de ovos deixados pelo predador em cada fruto. O formato extremamente achatado das sementes de Mimosa...

Germinação e desenvolvimento pós-seminal de Tibouchina moricandiana (DC) Baill. (Melastomataceae)
Provedor de dados: Acta Botanica Brasilica
Autores: Andrade,Antonio Carlos Silva de; Pereira,Tânia Sampaio.
Estudou-se o efeito de diferentes temperaturas (20,25, 30, 35 e 30-20ºC) sob condição de luz (fotoperíodo de oito horas) e escuro sobre a germinação de sementes de Tibouchina moricandiana (DC) Baill. Posteriormente, estudou-se a morfologia do desenvolvimento pós-seminal, visando o conhecimento das estruturas essenciais da plântula. Os resultados demonstraram que a temperatura ótima para a germinação de sementes foi de 30ºC; as temperaturas de 20 e 35ºC causaram o decréscimo da porcentagem e da velocidade de germinação. As sementes são tipicamente fotoblásticas positivas, necessitando de vários dias de exposição a luz para alcançar a máxima germinação. O estudo do desenvolvimento pós-seminal permitiu classificar a plântula como faneroepígea, típica de...

Seed production and seed quality of the dune building grass Panicum racemosum Spreng
Provedor de dados: Acta Botanica Brasilica
Autores: Cordazzo,Cesar Vieira; Davy,Anthony John.
Seed production, pollination requirement, seed characteristics related to quality and the relationship between number and mass of seeds were examined for Panicum racemosum in three successional populations in southern Brazilian coastal dunes. The seed production was generally low and declined further between the frontal dunes and the backdunes, dropping from 4.05 seeds per panicle in the former to 1.8 seeds in the latter. However fertility (% fertile florets) did not differ among the three habitats. Plants cross-pollinated in a glasshouse showed an increase in seed production to 41.4 seeds compared to no seed production in self-pollinated plants. Caryopses varied in mass from 3.2 to 12.2 mg with a mean of 7.98 mg. A strong negative correlation was found...

Root carbohydrate storage in young saplings of an Amazonian tidal várzea forest before the onset of the wet season
Provedor de dados: Acta Botanica Brasilica
Autores: Scarano,Fabio Rubio; Cattânio,José Henrique; Crawford,Robert M.M.
Root starch and glucose content were measured for young saplings of 18 Amazonian tidal várzea tree species during a dry season. The pattern of carbohydrate storage depended on the type of plant involved and soil topography which is directly linked to flood regime. Most plants showed high root carbohydrate content at this point in the dry season, however, several typically flood-tolerant species (particularly palm trees) presented a low root carbohydrate content, suggesting a strategy of acquiring reserves during the wet season to survive the dry season, when depletion occurs. Plant survival in these flood-prone forests seems to be the result of more than only one adaptive mechanism.

FLORECIMIENTO DE MICROALGAS RELACIONADO CON MORTANDAD MASIVA DE PECES EN EL COMPLEJO LAGUNAR CIÉNAGA GRANDE DE SANTA MARTA, CARIBE COLOMBIANO
Provedor de dados: Boletín de Investigaciones Marinas y Costeras (INVEMAR)
Autores: Mancera P.,José Ernesto; Vidal V.,Luís Alfonso.
Entre los meses de julio y agosto de 1994 un fenómeno discontinuo de muerte masiva de peces se registró en aguas del complejo lagunar de la Ciénaga Grande de Santa Marta, Colombia. El primer evento se presentó del 15 al 19 de julio, el segundo alrededor del día 20 de agosto y el tercero entre el 26 y 31 del mismo mes. La presencia en altas concentraciones de la cianofita filamentosa Cf. Anabaenopsis sp., registrada en la literatura como altamente tóxica, podría estar relacionada con las causas del primer evento. Un incremento en las concentraciones de fósforo, y un posterior florecimiento de nano y picoplancton, especialmente cianofíceas y algas flageladas, explicaría en parte las condiciones hipóxicas y anóxicas observadas en el tercer evento, las cuales...

Provedor de dados: Boletín de Investigaciones Marinas y Costeras (INVEMAR)
Autores: Ortíz,Manuel.
El estudio de los anfípodos, dada su gran importancia ecológica, se ha incrementado considerablemente en los últimos años. Los del Atlántico occidental tropical, no han sido una excepción. La complejidad de su estudio es tal que resulta rara la inclusión de familias, géneros o especies de este grupo en trabajos ecológicos dei bentos del área. Se presenta una clave gráfica que permite identificar con relativa facilidad las 36 familias y los 137 géneros de anfípodos del suborden Gammaridea (excepto los dulceacuicolas) de la mencionada región. No se conoce ningún precedente en la literatura especializada sobre anfípodos, de una clave como esta, al menos hasta el nivel genérico.

Trocas gasosas e condutância estomática em três espécies de gramíneas
Provedor de dados: Bragantia
Autores: Machado,Eduardo Caruso; Lagôa,Ana Maria Magalhães Andrade.
Avaliou-se, sob condições naturais e sem deficiência hídrica, o comportamento diário das taxas de assimilação de CO2 (A) e de transpiração (E), a condutância estomática (g) e a eficiência fotossintética do uso de água (E/A) em milho (C4), arroz (C3) e trigo (C3). Nas três espécies, a curva de resposta de A em função da irradiância (I), apresentou a forma de uma hipérbole retangular, porém em milho não houve saturação lumínica. A resposta de g em relação a I apresentou a mesma forma, respondendo E linearmente, nas três espécies. Em relação à variação de g, a curva de resposta de A também mostrou a forma de hipérbole retangular, enquanto E respondeu linearmente. Devido à resposta diferencial de A e de E, tanto em função de I como de g, a razão E/A aumentou...

Avaliação preliminar de perdas na produção devidas a nova anormalidade do algodoeiro no Brasil
Provedor de dados: Bragantia
Autores: Chiavegato,Ederaldo José; Fuzatto,Milton Geraldo; Cia,Edivaldo; Pettinelli Júnior,Armando.
Foram determinadas, em condições de campo, as perdas na produção do algodoeiro devidas a nova anormalidade, de causa desconhecida, à qual os autores se referem como "murchamento avermelhado". Mediante marcação de plantas afetadas - excluídas as que já se encontravam secas ou mortas - realizadas aos cem dias de idade, estabeleceram-se três grupos, de acordo com a intensidade crescente de sintomas, cujas produções foram comparadas com a do grupo de plantas aparentemente normais. Diferenças altamente significativas foram verificadas entre os grupos e, mediante análise de regressão (r² = 0,996), perdas esperadas de 16, 33 e 49% foram estimadas na produção média das plantas, à medida que crescia a severidade dos sintomas. Embora rebrotas ou aparente...

Sistema radicular e nutrição da soja em função da compactação do solo
Provedor de dados: Bragantia
Autores: Rosolem,Ciro Antonio; Almeida,Ana Cristina da Silveira; Sacramento,Luiz Vitor Silva do.
A compactação do solo diminui o crescimento radicular, podendo afetar tanto o desenvolvimento quanto a produtividade da soja. No presente trabalho, estudaram-se os efeitos da compactação subsuperficial na morfologia radicular da soja (Glycine max L. Merrill), procurando relacioná-los ao crescimento e à nutrição da planta. O 'Primavera' foi cultivado até os 37 dias da emergência, em vasos onde a camada de 15-18,5 cm de profundidade foi campactada a 1,03, 1,25, 1,48 e 1,72 g/cm³, em um latossolo vermelho-escuro com 80% de areia e 16% de argila e cuja compactação em subsuperfície levou a um acúmulo de raízes na camada superficial do vaso, sem grandes conseqüências na nutrição da planta. Na densidade aparente de 1,72 g/cm3, as raízes não conseguiram penetrar,...

Autores: Tulmann Neto,Augusto; Cristofani,Mariangela; Mendes,Beatriz Madalena Januzzi; Ando,Akihiko.
Para futuros trabalhos com indução de mutação "in vitro", determinou-se a sensibilidade de diferentes explantes do cultivar de laranja Pêra (Citrus sinensis Osbeck) a raios gama visando a escolha das doses a utilizar. Para isso, após a irradiação, avaliou-se o número de explantes responsivos, de embrióides e de brotações adventícias, a massa do calo e a formação de enraizamento. Resultados diferentes foram obtidos de acordo com o tecido empregado. Assim, para a irradiação de nucelos, recomenda-se o uso de doses entre 20 e 40 Gy; em calos embriogênicos, de 120 Gy e, para a irradiação de cotilédones de embriões nucelares, a dose situa-se ao redor de 40 Gy.

Provedor de dados: Bragantia
Autores: Mascarenhas,Hipólito Antonio Assunção; Tanaka,Roberto Tetsuo; Miranda,Manoel Albino Coelho de; Carmello,Quirino Augusto de Camargo; Oliveira,Fábio Álvares de.
Uma das inviabilidades econômicas da agricultura praticada em solos de baixa fertilidade é a acidez elevada que geralmente resulta em toxicidade de manganês (Mn) às plantas. O desenvolvimento de cultivares tolerantes a essa limitação química do solo resultará em benefícios sociais, pela redução do custo de produção. Com esse objetivo, foi desenvolvido um experimento com a linhagem de soja que mostrara, em ensaio preliminar, tolerância a altos teores de Mn em solução nutritiva. O cultivar IAC-Foscarin 31, que deu origem à linhagem, foi ensaiado como testemunha. Ambos os genótipos foram cultivados em vasos contendo latossolo roxo com excessiva disponibilidade de Mn. As plantas da linhagem foram sempre vigorosas, três vezes mais altas do que as do...

Aplicaram-se, por ano e por cova, 40 litros de esterco quando na ausência de NPK e 20 litros quando com NPK. A adubação mineral constou da utilização de 120 g de N, 40 g de P2O5 e 120 g de K2O por ano e por cova; quando em presença de esterco, usou-se metade dessas doses. O calcário foi aplicado na quantidade de 1 kg por ano e por cova, e zinco e boro, na quantidade de 20 g de sulfato de zinco...

Retenção de zinco em solos paulistas
Provedor de dados: Bragantia
Autores: Cunha,Rodrigo César de Araújo; Camargo,Otávio Antonio de; Kinjo,Toshiaki.
Para avaliar os atributos do solo que têm maior influência na retenção de zinco, desenvolveram-se experimentos de laboratório com amostras de horizontes superficial e subsuperficial de quatro latossolos, dois podzólicos e uma terra roxa estruturada de grande importância geográfica e econômica no Estado de São Paulo. No experimento de retenção, as amostras foram equilibradas com soluções de Zn nas concentrações 0,0, 0,3, 0,6, 0,9, 1,5, 3,0, 6,0, 9,0, 12,0 e 24,0 (x 10-3)mg/dm³ de Zn usando-se uma solução de CaCl2 na concentração de 2 mol/m³ como suporte. Correlacionaram-se os coeficientes das equações de Langmuir e Freundlich com os diversos atributos do solo. Tendo em vista a possibilidade de estimar a energia de ligação e a adsorção máxima de zinco pelos...

Provedor de dados: Bragantia
Autores: Tulmann Neto,Augusto; Ando,Akihiko; Sabino,José Carlos.
Para a indução de mutantes com maior altura basal (soma das alturas do hipocótilo e epicótilo), sementes de feijoeiro (Phaseolus vulgaris L.) cultivar Carioca 80 foram irradiadas com raios gama. Um mutante que apresentou altura basal 1,7 vez maior que o controle foi obtido na geração M2, do tratamento com 24 krad. A mutação foi monogênica devido a um alelo recessivo. Trata-se do primeiro mutante obtido por indução de mutação, para tal característica.

Autores: Amaral Júnior,Antonio T.; Casali,Vicente Wagner D.; Cruz,Cosme Damião; Silva,Derly José H. da; Silva,Luiz F. Corbeira da.
Sete caracteres morfoagronômicos, avaliados em oito acessos de moranga (Cucurbita maxima Duchesne) foram submetidos à análise de correlações fenotípicas, genotípicas e de ambiente. As correlações genotípicas foram superiores às fenotípicas e de ambiente, indicando moderada influência deste último na expressão dos caracteres. Todos os pares de caracteres apresentaram correlações genotípicas positivas (&gt; 0,75), evidenciando que a seleção para aumento na média de um caráter provocará alterações na média do outro, no mesmo sentido. Os caracteres comprimento da rama principal até a primeira flor feminina (RAMA F) e o comprimento da rama principal até o ápice (RAMA T) apresentaram a maior correlação genotípica, enquanto a menor magnitude dessa correlação...

Provedor de dados: Bragantia
Autores: Camargo,Marcelo Bento Paes de; Ortolani,Altino Aldo; Arruda,Hermano Vaz de.
Verificou-se o ajuste dos dados mensais de freqüência de rajadas máximas diárias de vento, referentes a uma série de vinte anos para Campinas (SP), aos modelos probabilísticos de distribuição "gama" e "normal". As freqüências observadas e as estimadas pela distribuição normal apresentaram melhor ajuste que aquelas pela distribuição gama para todos os meses. A partir da distribuição normal, quantificaram-se as probabilidades mensais de ocorrência de rajadas máximas diárias. Setembro a novembro apresentaram maiores probabilidades de rajadas acima de 20, 30 e 40 km/h, e maio e junho, as menores. Para velocidades de 10 e 50 km/h, não se observou sazonalidade pronunciada.

Autores: Amarante,Luciano do; Lopes,Nei Fernandes.
O experimento foi desenvolvido em condições de casa de vegetação em Viçosa (MG). Os efeitos de doses de quinclorac sobre características morfológicas do arroz (Oryza sativa L. cv. Inca) irrigado foram avaliados aos 7, 14 e 21 dias após o tratamento. O 'Inca' mostrou alta tolerância ao herbicida. A área e a massa seca foliares, aos 21 dias após o tratamento, foram inibidas em 50% somente com doses, respectivamente, 5 e 7 vezes maiores do que a recomendada. A altura das plantas não foi reduzida pelo quinclorac até a última colheita e nenhum sintoma visual de fitotoxicidade foi detectado.

Autores: Cervellini,Genésio S.; Igue,Toshio.
Foram plantados, em um latossolo roxo da região de Ribeirão Preto e em um podzólico vermelho-amarelo orto da de Mococa, dois experimentos com cafeeiro Bourbon Vermelho. Os tratamentos com nitrogênio, fósforo, potássio e esterco constituíram um fatorial 2(4) em quadrado quase latino com quatro repetições. Foram analisados os dados de produção, obtidos em três períodos de quatro anos. O efeito do esterco foi significativo nos dois solos, sendo maior no latossolo roxo, enquanto o nitrogênio, também significativo em ambos, destacou-se no podzólico vermelho-amarelo orto. O potássio apresentou pequeno efeito somente no latossolo roxo, cuja análise de terra revelou menor teor do elemento.

Variação na qualidade culinária das raízes de mandioca
Provedor de dados: Bragantia
Autores: Lorenzi,José Osmar.
A falta de regularidade na qualidade culinária das raízes de mandioca de mesa é um dos fatores de restrição à expansão de seu consumo. Raízes cozidas de boa qualidade, entre outras características, devem apresentar-se, quando esmagadas por um garfo, na forma de uma massa não encaroçada, plástica e não pegajosa. O tempo de cozimento culinário correlaciona-se bem com a qualidade da massa cozida, isto é, quanto menor esse tempo, melhor a massa gerada. Dessa forma, neste trabalho, a duração do tempo de cozimento (DTC) foi usada como método indireto e expedito para avaliação da qualidade culinária das raízes de mandioca. Os fatores que interferem na DTC podem ser reunidos em dois grupos: (a) intrínsecos: variação dentro e entre raízes da mesma planta e entre...

El estado ecuatoriano y la población indígena 1830 - 1860
Provedor de dados: Buscador Latinoamericano de Ciencias Sociales
Autores: Toche Medrano, Eduardo.
La Independencia fue un acontecimiento que provoco situaciones inéditas. La ruptura política que marcó el fin del periodo colonial, genera la necesidad de elaborar un nuevo discurso, que diera legitimidad a los regímenes republicanos recién inaugurados. Era claro que las bases fundamentales que debían regir la existencia de la República, tenían que diferenciarse nítidamente de aquellas que habían sustentado el ordenamiento colonial contra el cual se estaba irrumpiendo. En la región andina la dimensión indígena fue un aspecto crucial en donde se localizó el debate del momento. No podía ser de otra manera, en tanto esta población presentaba factores decisivos para dilucidar sobre la naturaleza de la República, al margen de su decisivo peso demográfico.

Provedor de dados: Ciência Rural
Autores: Santos,Ivo Walter dos; Neves,Jairo Pereira.
Para caracterização Geográfica da involução uterina e reinício da atividade ovariana, o puerpério de 15 vacas da raça charolesa foi acompanhado pela ultra-sonografia a partir do 8° dia, com intervalo de 3 dias, até o 40° dia pós-parto. Utilizou-se um aparelho de ultra-som Pie Medical Inc., mod. 450 com transdutor de 5MHz, arranjo linear e uma impressora. A involução completa do útero foi detectada aos 28,12±1,55 dias nas vacas com parto eutócico e aos 32,57±1,13 dias nas vacas com parto distócico, e o conteúdo uterino não foi mais visualizado aos 18,87±1,12 dias e 25,28±1,38 dias, respectivamente, após o parto. O curso do puerpério foi testado por regressão linear e quadrática, quando observou-se uma diferença altamente significativa entre partos eutócico...

AFLATOXINAS - ASPECTOS CLÍNICOS E TOXICOLÓGICOS EM SUÍNOS
Provedor de dados: Ciência Rural
Autores: Mallmann,Carlos Augusto; Santurio,Janio Morais; Wentz,Ilmo.
Aflatoxinas são metabólitos fúngicos produzidos por linhagens de Aspergillus flavus var. parasiticus encontrados ubiquitariamente nos substratos alimentares que compõe a dieta dos suínos. A aflatoxicose dos suínos é uma doença dependente da dose ingerida e do tempo de exposição, caracterizando-se principalmente pela atividade hepatotóxica desta micotoxina. Na suinocultura os maiores problemas são provocados por doses subclínicas onde esta intoxicação se manifesta na forma de prejuízos sobre o desempenho traduzidos principalmente por uma baixa conversão alimentar e por imunodepressão.

Provedor de dados: Ciência Rural
Autores: Dorneles,Liane Terezinha; Oliveira,Antônio Costa de; Siebeneichler,Susana Cristine.
RESUMO Plantas de feijão foram regeneradas via organogêse, a partir de sementes da cultivar FT 83-120 germinadas em meio MS acrescido de vitaminas B5. Explantes caulinares contendo 3/4 do nó-cotiledonar foram submetidos a três cultivos sucessivos, com intervalos de 21 dias cada um, em três concentrações de BAP (Benzil-aminopurina). A formação de brotos ocorreu entre o sexto e o oitavo dia de cultivo, a partir do eixo embrionário, sendo influenciado pelo tempo de cultivo e pelas concentrações de BAP. Os brotos foram enraizados em meio MS acrescido de 2µM/I de ANA (Ácido Naftaleno Acético) e 0,5µM/I de GA3 (Ácido Giberélico). As plantas obtidas foram transferidas para o solo e aclimatadas em casa de vegetação, onde cresceram até o amadurecimento.

ASPECTOS PECULIARES DO DESENVOLVIMENTO DO TIMO EM SUÍNOS
Provedor de dados: Ciência Rural
Autores: Sincai,Mariana; Marcu,Adrian.
RESUMO O desenvolvimento morfometabólico do timo foi estudado na ontogenia pré e pós-natal em suínos. Os estudos indicam que o timo já está organizado muito cedo durante o período pré-natal, por volta dos dois meses de prenhez. Os estudos histoquímicos indicam uma intensa atividade secretora das células reticuloepiteliais e também dos corpúsculos tímicos. Os estudos histológicos no período pré-natal revelaram uma presença maciça de corpúsculos tímicos e a existência de algumas células mióides que aumentavam paralelamente com o desenvolvimento no timo. Quando já adulto não existe uma involução completa do timo pois parte das funções secretora e hematopoiéticas são mantidas por algumas células.

OBSERVAÇÃO SOBRE O DESENVOLVIMENTO DE PLACENTA EM ALGUNS ROEDORES
Provedor de dados: Ciência Rural
Autores: Sincai,Mariana; Marcu,Adrian.
RESUMO A placenta do cobaio, rato, camundongo e ratão do banhado (Myocastor coypus) foram estudadas e revelaram aspectos interessantes. A placenta nestas espécies é do tipo discoidal no início da gestação e após a união entre a mucosa uterina com as vilosidades coriônicas passa a ser do tipo hemocorial. O exame microscópico da placenta da cobaia e do ratão do banhado era do tipo multilobular, enquanto que a placenta do rato e do camundongo parece a metade de um lóbulo da placenta de cobaia e do ratão do banhado. Esta observação poderia ser uma prova para a evolução filogenética dos roedores. O exame microscópico da placenta dos roedores revelou passagem de linfócitos através dos trofoblastos embrionários para o feto, o qual precisa de imunidade placentária.

Autores: Balardin,Ricardo Silveiro; Facco,Milto José.
RESUMO O objetivo do experimento foi avaliar a eficiência e fitotoxicidade de cinco fungicidas aplicados no tratamento de sementes para o controle de Drechslera teres, agente causal da mancha reticulada em cevada. A produtividade da cultura foi afetada pelos fungicidas testados. Os fungicidas tebuconazole e triadimenol reduziram a altura das plântulas. enquanto que o difenoconazole reduziu significativamente a matéria seca (30g/100kg de sementes). O efeito dos fungicidas sobre a emergência mostrou que difenoconazole (30g/100kg de sementes) e iprodine + thiram possibilitaram as maiores percentagens. Os fungicidas reduziram a incidência da Drechslera teres, o comprimento do coleóptilo e das radículas.

Provedor de dados: Ciência Rural
Autores: Lopes,Sidinei José; Storck,Lindolfo; Garcia,Danton Camacho.
Estudou-se o efeito de três formas de adubação sobre o erro experimental. As formas constituíram-se de: adubação para rendimento menor que 3t/ha; adubação para rendimento maior que 6t/ha e tratamento de sementes com Zn; e adubação para rendimento maior que 6t/ha, tratamento de sementes com Zn e incorporação ao solo de um fertilizante orgânico. O delineamento experimental utilizado para as formas de adubação foi inteiramente casualizado com quatro repetições. Cada repetição das formas de adubação foi composta por duas cultivares de milho híbrido igualmente e aleatoriamente repetidos. Os resultados mostraram que uma forma de adubação constituída por vários componentes provoca maior erro quando comparada com formas mais simples. O aumento do nível de...

FATORES QUE AFETAM A EXPRESSÃO SEXUAL EM PLANTAS DE PEPINO
Provedor de dados: Ciência Rural
Autores: Menezes,Nilson Lemos de.
RESUMO O artigo descreve a morfologia floral e os principais fatores que afetam a expressão sexual das plantas de pepino (Cucumis sativus L.) incluindo fatores genéticos, fotoperíodo, temperatura, nutrição, reguladores de crescimento e outros. Em pepino, como nas demais espécies da família Cucurbitaceae, a produção de frutos está na dependência direta da floração feminina, dos diversos tipos sexuais, os quais são controlados por fatores genéticos, ambientais e hormonais. A ação dos hormônios e outros produtos, capazes de afetar a expressão sexual, ocorre somente em nível fisiológico. O número de nós, à partir das folhas cotiledonares, até o nó que contém a primeira flor feminina, na haste principal, é uma boa medida da tendência sexual e da precocidade da...

SUMMARY Ovine mastitis causes varying economic fosses in all countries where sheep are kept. A survey of 3128 breeding ewes in 22 farms in two areas with different management practices in Southern Brazil showed that the average prevalence of subclinical and chronic mastitis was 14.1% of ewes with at least one affected gland. From those, 4.49% were also bacteriologically positive. The prevalence in individual farms varied from 0 to 37% of ewes with clinical abnormalities of the udder. The overall prevalence was greater in Area II, where meat breeds predominate and animals are housed at night. It is concluded that subclinical and chronic mastitis is uniikely to be an economic problem in Area I, where wool production is the objective of the sheep industry....

Autores: Streck,Nereu Augusto; Schneider,Flavio Miguel; Buriol,Galileo Adeli.
SUMMARY Temperature modification in soil of plastic greenhouse caused by solarization was measured during the summer in the Subtropical Central Region of the Rio Grande do Sul State, Brazil. The experiment was carried out in a 10m x 25m greenhouse covered with low density transparent polyethylene (PE). Four 6m x 4m plots were mulched with 100µm thickness PE sheets, from December 12, 1992 to March 7, 1993. Four other plots (same size) without the cover were used as control (bare soil). Results indicated that solarization incrased the maximum soil temperature. The average was 11.9, 10.8, 9.8, and 8.6°C over uncovered control soil at 2, 5, 10, and 20cm depth, respectively. The soil temperature reached values of up to 54.4°C at 2cm and 50.2°C at 5cm depth....

RESUMO Quantificou-se a modificação na temperatura do solo de uma estufa plástica causada pela solarização, durante o verão, em Santa Maria, RS. O experimento foi conduzido no interior de uma estufa de polietileno transparente de baixa densidade (PEDB) de 10m x 25m. A solarização foi feita em quatro parcelas de 6m x 4m utilizando PEDB 100pm de espessura. no período de 17/12/92 a 07/03/93. Quatro parcelas de mesmas dimensões foram mantidas sem cobertura (solo desnudo). Os resultados mostram que a temperatura máxima no solo solarizado foi, em média, 11,9°C, 10,8°C, 9,8°C e 8,6°C maior do que no solo não solarizado, nas profundidades de 2, 5, 10 e 20cm, respectivamente. Constata-se também que ocorreram valores absolutos de 54,4°C e 50,2°C nas profundidades de...

Provedor de dados: Ciência Rural
Autores: Balardin,Ricardo Silveiro; Verona,Luiz Augusto; Rebelo,José Angelo.
RESUMO Este trabalho foi conduzido com o objetivo de avaliar o comportamento de materiais inertes para controle de tombamento durante a emergência. Os tratamentos foram cobertura do sulco de semeadura com areia e serragem, tratamento químico com brometo de metila e uma testemunha. Os parâmetros avaliados foram percentagem e velocidade de emergência, percentagem de tombamento de pré e pós-emergência. Os dados obtidos permitiram concluir que, dentre os materiais inertes testados, a areia pode constituir-se em uma alternativa eficiente no controle do tombamento em sementeiras de repolho e beterraba, pois permitiu o maior número de plântulas emergidas e o menor número de plântulas tombadas não alterando a velocidade de emergência, enquanto que nas sementeiras...

PESTE SUÍNA CLÁSSICA: UMA ATUALIZAÇÃO EM MÉTODOS DE DIAGNÓSTICO LABORATORIAL
Provedor de dados: Ciência Rural
Autores: Roehe,Paulo Michel; Rosa,Julio Cesar de Almeida; Oliveira,Liliane Guimarães.
RESUMO Neste artigo são revisados os diferentes métodos internacionalmente utilizados no diagnóstico de Peste Suína Clássica (PSC). A detecção rápida de antígenos virais é feita através do exame direto de cortes em criostato dos tecidos de animais, por imunofluorescência direta (IF). O diagnóstico é confirmado pelo isolamento do vírus em cultivos celulares. A detecção de anticorpos contra o vírus é baseada em testes de soroneutralizaçâo seguidos de IF, imunoperoxidase (IPX), ou ensaios imunoenzimáticos. Anticorpos monoclonais são úteis na distinção entre o vírus da PSC e outros pestivírus que podem eventualmente infectar os suínos. Técnicas moleculares, como hibridização, reação de polimerase em cadeia (PCR) e seqüenciamento, ainda não são empregadas...

OS CAMPONESES FACE À EXTENSÃO RURAL
Provedor de dados: Ciência Rural
Autores: Marin,Joel Orlando; Rossato,Ricardo.
RESUMO O artigo aponta que as práticas sociais dos camponeses frente à Extensão Rural são ambíguas e contraditórias, resultando em conformismo e resistên-cia. Por um lado, a supremacia do conhecimento científico, o caráter impositivo das práticas educacionais extensionistas, o controle através do crédito agrícola e dos pacotes tecnológicos são mecanismos de imposição de novos conhecimentos e tecnologias que, assi-milados pêlos camponeses, conformam-nos à hegemonia da sociedade capitalista. Por outro lado, os camponeses resistem à essa racionalidade tecnológica, fundamentando-se em sua forma própria de organizar a produção agrícola, na sua cultura e saberes adquiridos em suas experiências de vida.

MORFOLOGIA E MORFOMETRIA DAS DILATAÇÕES GLANDULARES NO ENDOMÉTRIO DA ÉGUA
Provedor de dados: Ciência Rural
Autores: Monteiro,Cristina Maria Rodrigues; Silva,Carlos Antônio Mondino; Barros,Severo Sales de.
RESUMO Os endométrios de 923 éguas foram revisados histologicamente para se verificar a presença de dilatações glandulares. O material se originou de 873 biópsias uterinas e 50 amostras uterinas de matadouro. Esta alteração foi detectada em 164 (18,8%) biópsias e em 23 (46%) casos de matadouro. Destas, 30 amostras de biópsia e 17 de matadouro foram analisadas morfológica e morfometricamente. A dilatação das glândulas endometriais estava associada à fibrose peri-glandular em 68,8% dos casos de biópsia e em 86,1% dos de matadouro. Não foi possível estabelecer a(s) causa(s) da dilatação glandular, mas os dados morfológicos sugerem um distúrbio local na relação entre os hormônios, as células do estrema, as células glandulares e a matriz extracelular.

RESUMO Em solo pertencente a Classe Terra Roxa Estruturada (Paleudult), nas estações do outono, inverno e primavera do ano de 1991, em Teutônia-RS, avaliou-se os efeitos de diferentes sistemas de cultivo (cultivo convencional, plantio direto e mata natural) sobre distribuição de agregados estáveis em água, Diâmetro Médio Geométrico (DMG) e população de oligoquetas. O DMG e população de oligoquetas foram mais elevados em solo sob mata natural em todas as estações, seguidos pelos das áreas de plantio direto e cultivo convencional. Isto evidencia que as frequentes incorporações da cobertura morta do solo, aliadas a fatores climáticos, têm grande influência sobre o DMG e a população de oligoquetas.

Autores: Siewerdt,Frank; Farias,José Viriato da Silva; Osório,José Carlos da Silveira; Jacondino,Ilo Francisco Ribeiro.
Data from 82 purebred and crossbred Large White and Duroc barrows and gilts were used to describe the growth of carcass primal cuts, of tissues, and of several organs. Pigs were allowed ad libitum to a conventional diet, which contained com and soybean meal. Pigs were weighted weekly and were slaughtered when attained a liveweight over 90kg. An allometric pattern of growth was assumed. Within the observed range of liveweight, the carcass grew slower than the whole animal. An increase of carcass weight corresponds to a similar increase of lean, but also corresponds to a larger increase of fat tissues. A suggestion to slaughter pigs near to 90kg of liveweight is presented, in order to obtain leaner carcasses.

Autores: Corrêa,Gilson Luiz Borges.
RESUMO A criptococose é uma enfermidade micótica, causada pela levedura denominada Cryptococcus neoformans, que tem distribuição cosmopolita. O agente etiológico já foi isolado de diversos materiais, incluindo: frutas, amostras de solo, fezes de aves principalmente de pombos. Apesar de ser encontrado como saprófita na natureza, o Cryptococcus neoformans pode produzir doença no homem e várias espécies de animais domésticos ou silvestres. Em gatos, essa levedura pode ser encontrada provocando infecções, especialmente nos pulmões, sistema nervoso central, região facial ou se manifestar de forma generalizada. A doença nos gatos, pode produzir sinais clínicos semelhantes aos de outras enfermidades necessitando, portanto, de uma definição diagnostica rápida e...

RESUMO Com o objetivo de avaliar o efeito da calagem, e da adubação com fósforo e com zinco no rendimento da pensacola (Paspaium notatum Flugge var. saurae P.) em solo franco arenoso, conduziu-se uni experimento em casa de vegetação na UFSM, utilizando-se delineamento inteiramente casualizado com quatro repetições. Os tratamentos foram a combinação de três doses de zinco (zero, 4 e 20ppm de Zn) e três doses de fósforo (zero, 30 e 150ppm de P2O5) com e sem acidez corrigida com calcário. Os resultados foram avaliados pelo rendimento de matéria seca, fósforo e zinco absorvidos pela planta. Observou-se interação entre calagem e fósforo e entre zinco e fósforo. O aumento de pH do solo pela calagem de 4,8 para 6,5, diminuiu o rendimento de matéria seca e o...

AVALIAÇÃO TEMPORAL DA UMIDADE DO SOLO COMO CONSEQÜÊNCIA DO TIPO E PERCENTAGEM DE COBERTURA VEGETAL
Provedor de dados: Ciência Rural
Autores: Campos,Ben-Hur Costa de; Reinert,Dalvan José; Albuquerque,Jackson Adriano; Nicolodi,Renato.
No sistema de plantio direto a cobertura vegetal do solo favorece a infiltração de água da chuva e/ou irrigação e diminui as perdas por evaporação, mantendo a umidade em valores mais elevados em períodos de estiagem, principalmente, na camada superficial. Este trabalho foi desenvolvido de maio de 1991 a maio de 1992, em área do Departamento de Solos, no Campus da UFSM. O objetivo foi avaliar o efeito de diferentes tipos de coberturas vegetais sobre a umidade da camada superficial do solo, para a cultura do milho cultivada em sistema de plantio direto. Os tratamentos constaram das espécies de inverno: chícharo (Lathyrus sativus), tremoço (Lupinus angustifolius), ervilhaca (vicia sativa), aveia preta (Avena strigosa) e pousio invernal, antecedendo a cultura...

O presente experimento teve por finalidade verificar o efeito na prenhez de diferentes técnicas de inseminação cervical com sêmen congelado, em 234 ovelhas Corriedale, em cio natural. Utilizou-se sêmen congelado em peletes de três carneiros Suffolk e um Corriedale. Cento e trinta e seis ovelhas foram inseminadas por via cervical, com (60) e sem (76) tração cervical. Como grupo controle, noventa e oito ovelhas foram submetidas à inseminação laparoscópica. Para a análise do índice de prenhez, verificado através da ecografia, os graus de penetração foram classificados em cervical superficial e profundo. Considerando-se todas as ovelhas submetidas à inseminação cervical, obteve-se resultados de prenhez de 44,19% e 32,26%, respectivamente para maior e menor...

Autores: Aude,Maria Isabel da Silva; Marchezan,Enio; Dariva,Thelmo; Pasqualetto,Antônio.
A adaptação de cultivares e o efeito da colheita anual na produção de colmos industrializáveis e outras características agronômicas da cana-de-açúcar foram verificadas em 10 cultivares em Santa Maria-RS. No experimento, instalado em outubro de 1983, foram realizadas cinco colheitas com intervalos de 12 meses. A colheita da cana-planta apresentou maior produtividade de colmos industrializáveis, decrescendo gradativamente nas colheitas seguintes. Foi possível fazer quatro cortes em colheitas anuais, visto que ocorreu drástico decréscimo na quinta colheita. Todas as cultivares testadas, com exceção da RB 72-5147 podem ser recomendadas aos produtores de cana-de-açúcar da região pois apresentaram alta produção de colmos industrializáveis e teor de sólidos...

AGENTES MUTAGÊNICOS E A INTENSIDADE DE VARIABILIDADE GENÉTICA NO CARÁTER ESTATURA DE PLANTAS DE AVEIA (AVENA SATIVA L.)
Provedor de dados: Ciência Rural
Autores: Nascimento Júnior,Alfredo do; Carvalho,Fernando Irajá Félix de; Neto,José Fernandes Barbosa; Federizzi,Luiz Carlos.
RESUMO Há evidências de que a variabilidade genética é um dos pontos básicos para o progresso da aveia no Sul do Brasil. O caráter adaptativo, como estatura da planta, poderá contribuir para o desenvolvimento da cultura, desde que existam diferenças genéticas para a seleção. Desta forma, a indução à mutação poderá ser um mecanismo eficiente no melhoramento da espécie. A azida sódica e o cobalto-60 foram testados na indução de mutações em duas variedades de aveia, UFRGS-7 e UFRGS-8, em diferentes doses. A média e a variância das gerações provenientes de sementes tratadas foram comparadas aos genótipos não tratados, evidenciando alteração genética no caráter estudado para todos os tratamentos. A azida sódica foi mais favorável para a indução de modificações...

BIOCHEMICAL POLYMORPHISMS IN SHEEP AND THEIR POTENTIAL USE FOR PATERNITY TESTS
Provedor de dados: Ciência Rural
Autores: Henkes,Luiz Ernani; Weimer,Tania de Azevedo; Moraes,José Carlos Ferrugem de.
The genetic variability of 22 protein loci was investigated in two sheep flocks: 22 females Romney Marsh and 124 animals derived from crossbreeding between Romney Marsh and Merino Booroola, reared by the Brazilian Agricultural Research Corporation (Empresa Brasileira de Pesquisa Agropecuária -EMBRAPA, Bagé, RS, Brazil). Eight loci were polymorphic; the others showed no variation. The usefulness of the eight plymorphic systems (Cat, DIA I, EP-1, EsA, HbB, ME, Tf, and X Prot.) in parentage tests was analyzed. The probability to find two random identical animals in each breed was estimated as 1:1000. The efficiency of these proteins for exclusion of one of two possible sires in parentage tests was about 77% both for Romney Marsh and Romney/ Booroola flocks....
