Биокартирование сообществ макробентоса Каламитского залива Черного моря: многомерная классификация в целях экологического мониторинга
Provedor de dados: 13
Autores: Погребов В.Г.; Ревков Н.К.; Рябушко В.И.
On basis of SCUBA samples obtained in summer period of 1989 on the depth up to 25 m, the distribution on macrobenthos in the region of intensive development of Mytilus mariculture is described. In order to select biocartography methods, which are most adequate for purposes of planned ecological monitoring, 14 variants of classification are tested (by dominants, by faunistic composition, structural on the basis of Czekanowski indices, Euclidian and MacNaughton — Smith distances by means of absolute and relative biomass values, for total and reduced on 2/3 massive of observations). The variants of polythethic classification are recognized as optimum and for the final presentation of information the results of structural classification by Czeka­nowski indices...

A pesquisa objetiva obter uma maior e mais uniforme brotacao das videiras na Regiao do Submedio Sao Francisco com o uso de diferentes praticas culturais e reguladores de crescimento de plantas. A cultivar utilizada foi a Italia, por ser a mais plantada na regiao e por apresentar o problema de baixa brotacao de gemas bem evidente. Os experimentos foram sempre instalados durante o periodo do ano de clima mais ameno, entre os meses de maio e agosto, quando o indice de brotacao e bastante reduzido.

Controle biológico do pulgão da inflorescência em cajueiro.
Provedor de dados: 14
Autores: BLEICHER, E.; MELO, Q. M. S.; ABREU, A. R. M. de.
O pulgão Aphis gossypii Glover, 1876 (Homoptera: Aphididae), é um inseto polífago, controlado naturalmente, em várias culturas, por uma série de agentes de controle biológico, principalmente predadores das ordens Coleopteras (família: Coccineliidae); Diptera (família: Syrphidae) e Neuroptera (família: Chrysopidae), bem como parasitóides da ordem Hymenoptera (família: Braconidae) cuja espécie mais comum é Aphidius testaceips (Cresson). A importância do controle biológico natural de uma praga, em determinada cultura, pode ser auferida pela exclusão dos inimigos naturaisde uma área comparada com outra onde esses não foram excluídos. São descritas várias técnicas de exclusão, entre elas destaca-se o uso de agroquímicos, que eliminam somente os insetos benéficos.

Autores: GRIGOLETTI JUNIOR, A.; SÔNEGO, O. R.
A escoriose da videira (Phomopsis viticola) é uma doença fúngica que vem preocupando por sua crescente incidência e eIevados danos causados. Em condições de alta umidade primaveril, o controle químico é necessário, principalmente em cultivares sensíveis. Nos anos de 1988 e 1989, foram conduzidos dois experimentos, em condições de campo na cultivar Cabemet Sauvignon, com o objetivo de avaliar a eficiência de fungicidas no controle da doença. As aplicações foram realizadas com pulverizador costal manual, na fase inicial de brotação (estádios P e E de Baggiolini), em plantas com sintomas previamente marcadas. Foi avaliada a percentagem de lesões na base do ramo ate o 4º entrenó. Os resultados obtidos demonstram que os fungicidas a base de Dithianona 75 PM...

Descrição de danos e dinâmica populacional das pragas e inimigos naturais que ocorrem na cultura do caupi (Vigna unguiculata ( L.) Walp.), em Rio Branco, AC.
Provedor de dados: 14
Autores: FAZOLIN, M.
O feijão caupi, vigna unguiculata (L.) Walp., é cultivado nas regiões tropicais da África, Ásia e América, constituindo-se na principal fonte de proteínas para as populações de baixa renda. No Estado do Acre, apesar de ser um produto bastante consumido, poucas variedades são cultivadas, pois a disponibilidade de sementes é limitada. Assim, o caupi participa com aproximadamente 10% do total da área destinada aos feijões comestíveis. As informações a respeito das pragas relacionadas com esta cultura, na região de Rio Branco são restritas, sendo necessário levantamentos e estudos de flutuação populacional visando a implantação de um programa de manejo integrado.

O cultivo do cajueiro (Anacardium occidentale L.) e bastante expressivo nos solos dos tabuleiros costeiros da regiao Nordeste Ocidental, em face da sua rusticidade e adaptabilidade as condicoes edafoclimaticas locais. A regiao litoranea do Ceara e constituida, igualmente, de solos arenosos com problemas de deficiencia hidrica e baixa fertilidade natural, exigindo o conhecimento detalhado de suas caracteristicas para o desenvolvimento das tecnicas de manejo mais apropriadas. Nestas areas, verifica-se uma exploracao continua para atender a demanda de alimentos e de materia-prima para a agroindustria do caju, intensificada pelo uso crescente de mecanizacao em substituicao ao trabalho humano.

Localizado a aproximadamente 9 graus de Latitude Sul e 62 graus de Longitude Oeste, o Projeto Machadinho, hoje transformado em Município de Machadinho d'Oeste, visou assentar 2934 famílias de agricultores sem terra, superando os problemas tradicionais da colonização agrícola em Região Equatorial. Em 1996, uma equipe de pesquisadores levantou cerca de 45% dos colonos, fornecendo uma visão circunstanciada dos agricultores e de seus sistemas de produção. No final de 1989, cientes das transformações ocorridas na região, os pesquisadores revisitaram os lotes estudados em 1986 e mais uma significativa amostra complementar de agricultores chegados nos últimos três anos. Este documento retrata, em 247 tabelas, um novo perfil agro-sócio-econômico dos agricultores e...

Hoje somos o Centro Nacional de Pesquisa de Agroindustria Tropical - CNPAT em substituicao ao Centro Nacional de Pesquisa de Caju - CNPCa. Com essa nova sigla, aumentam nossos compromissos com a sociedade brasileira, na medida que acrescentamos novas culturas as nossas atividades de pesquisa e ousamos nos envolver, enfim, no setor da agroindustria. Mesmo assim, o caju e o carro-chefe do CNPAT, motivo pelo qual foi criado o personagem eleito pelos empregados desta unidade de pesquisa com o nome cajulino. Atualizando dados, passamos a ser Embrapa Agroindústria Tropical. Assuntos: Como coletar amostra de solo. Adubação. Recomendações após o plantio. Pragas que ocorrem na floração e frutificação: traça-da-castanha, pulgão-da-inflorescência, mofo-preto....

Em cada uma foram avaliadas 28 paniculas por ponto cardeal; dezesseis colhidas aos 30, 45, 60 e 75 dias e as outras dize observadas diretamente nas plantas. Em cada panicula tomaram-se o comprimento, o numero de ramificacoes, de botoes florais, de flores masculinas e hermafroditas, a duracao do florescimento e o numero de frutos jovens e colhidos. Nas paniculas estufadas em laboratorio foram estimados a media e o intervalo de confianca por epoca de coleta, dentro e entre cada ano de observacao e, nas avaliadas em campo, as medias anuais para cada carater avaliado....

Autores: SANTOS, S. A.; SILVA, M. P. da; MAURO, R. de A.
Entre os herbivoros que habitam o Pantanal, destaca-se o cavalo Pantaneiro, importante para o desempenho das atividades agropecuarias da regiao. A maioria dos pecuaristas mantem os cavalos juntamente com os bovinos, onde as pastagens nativas constituem a base alimentar da regiao. Este estudo foi conduzido no periodo de marco de 1990 a fevereiro de 1991, na fazenda Nhumirim da EMBRAPA-CPAP, Pantanal da Nhecolandia, para identificar a preferencia alimentar, uso do habitat, disponibilidade e composicao quimica das forrageiras consumidas pelo cavalo Pantaneiro, em diferentes epocas do ano. Na epoca da cheia (out./marco), de 31 forrageiras, as mais consumidas em importancia de ocorrencia foram Reimarochloa brasiliensis (28,3%), Axonopis purpusii (14,7%),...

Avaliação de sementes de caupi quanto ao ataque do caruncho em diferentes condições de armazenamento.
Provedor de dados: 14
Autores: FAZOLIN, M.; MESQUITA, J. E. de L.
O caupi, Vigna unguiculata, (L.) Walp. é cultivado na região Norte do Brasil como cultura de subsistência, sendo que os pequenos excedentes de produção são destinados à comercialização, evidenciando desta forma, a importância socioeconômica desta cultura. Vários são os fatores que contribuem para a queda de produção da cultura do caupi. No armazenamento são encontrados insetos que conprometem significativamente a qualidade e a quantidade dos grãos e sementes produzidos. O objetivo do ensaio foi o de encontrar, dentro das limitações do pequeno produtor rural acreano, condições eficientes de armazenamento de sementes de caupi, observando a adoção de recipientes e controle químico do gorgulho.

Efeito da simulação de dano de inseto pela despaniculação na produção de cajueiro anão precoce.
Provedor de dados: 14
Autores: BLEICHER, E.; FURTADO, I. P.; MELO, Q. M. S.
Uma das principais pragas do cajueiro, Anacardium accidentale L., é a broca-das-pontas, que ataca a inflorescência onde a larva broqueia a medula, ocasionando o seu secamento. A exemplo de outras culturas, é possível que também o cajueiro possa tolerar uma perda parcial de suas estruturas de reprodução sem que haja danos de caráter econômico. Nesse experimento preliminar, procura-se verificar o efeito da retirada de inflorescências na produtividade da cultura, bem como definir princípios metodológicos para estudos mais detalhados.

RECOMENDAÇÕES técnicas para o cultivo do feijão: zonas 67, 70, 72, 75, 76, 87, 90 e 92.
Provedor de dados: 14
A partir do Delineamento Macroagroecológico, realizado pelo Serviço Nacional de Levantamento e Conservação de Solos, foram selecionadas regiões brasileiras homogêneas com destacada participação na produção da cultura do feijão no País, de acordo com os registros do Instituto Brasileiro de Geografia e Estatística. O objetivo é caracterizar a forma de condução das lavouras de feijão nas zonas estudadas, identificando as principais restrições à produtividade e indicando as tecnologias capazes de superá-las ou amenizá-las. O dinamismo da tecnologia agropecuária não permite que consideremos as recomendações aqui apresentadas como "encerradas" em sua totalidade, pois a pesquisa introduz a cada momento novos procedimentos e ações que visam a melhoria da...

Sistema de cultivo de citros com culturas intercalares.
Provedor de dados: 14
Autores: COELHO, Y. da S.
A necessidade de aumentar a eficiencia no uso da terra induz os produtores a exploracao de culturas intercalares nos pomares. Tipica de pequenas propiedades, a pratica das culturas associadas permite o ingresso de capital a curto prazo, visto que a producao economica dos citros apenas se inicia a partir do terceiro ano. Paralelamente, minimizam-se os riscos decorrentes do monocultivo e se estimula a utilizacao intensiva das terras mais nobres disponiveis para a agricultura. No presente trabalho, e apresentado o desempenho de dez culturas intercalares, a expectativa de rendimento, os cuidados necessarios e os coeficientes tecnicos para a exploracao.

Interprétation des stries valvaires pour l'évaluation de la croissance de Ruditapes decussatus L.
Provedor de dados: 5
Autores: Garcia, F.
Counting annual rings on shells, under favourable climatological conditions, usually permits determination of the age of many bivalves. But the application of this method becomes impossible when meteorological conditions are highly variable, as in the Bay of Fos. Annual winter rings are, in fact, often merged with other rings induced by important physiological processes like gametogenesis. When, therefore, annual rings and pseudoannual rings occur, it is impossible to distinguish between them. SEM offers a good solution to this problem, through the establishment of a scheme of interpretation. This method would also be suitable to identify the two main types of rings that could be confused in Ruditapes decussatus L. of the Bay of Fos, using optic microscopy...

Rôle du plancton dans le cycle biogéochimique du cadmium et du vanadium en baie de Seine orientale : premiers résultats
Provedor de dados: 5
Autores: Miramand, P; Bentley, D; Guary, Jc; Brylinski, Jm.
Cd and V were analyzed in planktonic species (zooplankton and diatoms), in flocks and in total seston (suspended materials) collected at eleven stations for seven sampling periods in the eastern area of the bay of Seine. Cd concentrations measured in planktonic species of the bay of Seine are identical to those measured in other oceanic areas, but V concentrations are generally higher. In the conditions of sampling, the role of both planktonic species and flocks in the horizontal fluxes of Cd and V in the bay of Seine appears not to be important (Cd) or negligible (V) compared to non-living materials (tripton). Nevertheless, this study should be continued in periods of diatom blooms. Flocks which present high Cd and V concentration probably have an...

Use of an ecosystem model for the assessment of the influence of cultivated oysters (Crassostrea gigas) on the nitrogen cycling in the Marennes-Oleron Bay
Provedor de dados: 5
Autores: Bacher, Cedric.
A model of the growth of cultivated oyster in the Marennes-Oléron bay was developped to assess the influence of the nutrients input and of the amount of oysters on the growth performance (Railiard. 1991). The ecosystem main characteristics are: - short residence time of the water. - high turbidity level, depending on the season, tidal level, bathymetry, currents and wind. The turbidity acts on the primary production through light limitation and on oyster production as a food dilution factor. - presence of high density cultivated areas on mid-tidal flats. The amount of oysters is ranging between 80 000 and 110 000 tons according to the year. - spatial variability of the biological and physical features. - coupling effects of the physic process (transport,...

Analysis of gear interactions in a hake fishery: The case of the Gulf of Lions (NW Mediterranean)
Provedor de dados: 5
Autores: Aldebert, Yvonne; Recasens, Laura; Lleonart, Jordi.
The hake of the Gulf of Lions is the most important target species of the demersal fishery. It is exploited by four types of gear (two trawls, gillnet and longline) used by two countries (France and Spain). Some analyses of its dynamics, based on 19 88 length frequency data by gear, have been performed. These analyses consisted in a VPA (Virtual Population Analysis). phis a Y/R (Yield per Recruit analysis) carried out on two parameter scenarios by sex, under a steady state hypothesis (with constant recruitment). Some estimates of biomass and exploitation level were obtained, and sensitivity to the biological parameters and interaction between types of gear were studied. As a main conclusion, it can be seen that the types of gear fishing mainly small...

Lymphocystis outbreaks in farmed sea bream, Sparus aurata, first report on French Mediterranean coast
Provedor de dados: 5
Autores: Le Deuff, Rose-marie; Renault, Tristan.
Among the Iridovirus related infections frequently described on many teleosts fish species, Viral Erythrocytic Necrosis (VEN) (Pinto et al., 1989), Epizootic Haematopoietic Necrosis Virus (EHNV) (Langdon et al., 1988) as weil as Lymphocystis Disease Virus (LDV) are not considered to directly cause fatality. Indeed, Lymphocystis outbreaks of farmed fish could be observed in some cases, as a consequence of a bacterial double infection or cannibalism (Ahne ef al., 1991; Moate et al., 1992). Here, we report for the first time a strong LDV infection, and an additional physical stress responsible for mortalities of reared sea bream, Sparus aurata, from Toulon area, on French Mediterranean coast. Although, since the first report of Lymphocystis in sea bream under...

Feeding of Crassostrea gigas at high seston load : modeling requirements
Provedor de dados: 5
Autores: Barille, Laurent; Prou, Jean.
Ecophysiological experiments conducted in situ in the Bay of Marennes-Oléron during a spring and neap tide cycle in May 1991 , were designed to get a better representation of 2 important components of the energy budget of the Japanese oyster Crassostrea gigas : clearance rate and selection efficiency. The relationships previously established by Raillard et al. ( 1993) are re-evaluated by integrating the effects of high seston loads, typical of tidal effect within estuaries, on the physiological processes. For the clearance rate, the re-evaluated parameterization includes: - a negative effect of turbidity. - a clogging threshold set to 192 mg/l. Selection efficiency parameterizations are modified by incorporating : - a constant inorganic ingestion for...

Monosaccharide composition of suspended organic particulate matter in relation to its origin
Provedor de dados: 5
Autores: Compiano, Am; Romano, Jc; Delagiraudiere, I; Laborde, P.
Samples of phytoplankton cultures and of suspended particulate matter from continental, brackish and marine waters were examined by HPLC for the monosaccharide content of their hydrolysable sugar fraction. Eight monosaccharides were currently assayed and their weight compared to HPLC-assayed chlorophyll a concentrations. With the exception of oligotrophic waters, these two variables are well correlated in the various prospected environments. Glucose was always the strongly dominant form, not only in fresh and brackish waters but also in marine samples with high phytoplanktonic biomass. If samples are compared on a salinity basis, only four monosaccharides showed significant differences in their relative concentrations, as a consequence of sampling...

Répartition des Noelaerhabdaceae (nannofossiles calcaires) dans le Quaternaire moyen et supérieur des océans Atlantique et Pacifique
Provedor de dados: 5
Autores: Pujos, A; Giraudeau, J.
Calcareous nannofossil assemblages of the family Noelaerhabdaceae have been studied in sediments of seventeen Quaternary cores raised from various climatic areas of the Atlantic and Pacific oceans. These sections display a regular, hiatus-free sedimentation for the last 500000 years. They have been dated using oxygen-isotopic measurements, variations of calcium carbonate content, variations of total nannofossil abundance, thorium measurements and volcanic ash horizons. Coccoliths of the genus Gephyrocapsa have been placed in three distinct taxonomic groups, based on morphological criteria inferred from light-microscope observations. Their acmes, as well as the acme of Emiliania huxleyi, are considered as stratigraphic markers. These markers characterize...

Autores: Quadfasel, D; Baudner, H.
High resolution synoptic hydrographic surveys carried out during 1982 to 1987 are used to delineate the two-dimensional baroclinic flow pattern of the Red Sea. it is shown that the circulation can be characterized through a succession Of four gyres, some 200 km in diameter, the locations of which are linked to the major topographic basins of the Red Sea. The gyres have a transport almost an order of magnitude larger than the large-scale thermohaline driven flow. They appear to be forced by the strongly rotational wind field over the Red Sea.

Elevage intensif du loup Dicentrarchus labrax
Provedor de dados: 5
Autores: Coves, Denis; Gasset, Eric.
Different seabass (Dicentrarchus labrax) intensiv rearing technics have been experimented in the pilot scale unit of our laboratory. During these upscalfing operation, the results obtained allow us to compare costs related to each fingemng production method. Closed system combined with early weaning with an efficient micropellet saves at least 69 % of direct production costs by comparison with an open system with Arternia during larval phase. However if closed systems are commonly used by private hatcheries, larval micropellets are always at experimental step.

Provedor de dados: 5
Autores: Hekinian, Roger; Bideau, Daniel; Francheteau, Jean; Cheminee, Jean-louis; Armijo, Rolando; Lonsdale, Peter; Blum, Norbert.
The Hess Deep, a rifted oval-shaped depression located east of the Galapagos Triple Junction at the tip of the Cocos-Nazca ridge (about 101-degrees-W, 2-degrees-N), was explored in 1988 during 21 submersible dives. A total of 11 dives were devoted to the exploration of the E-W trending Intrarift ridge (15 km in length, 3000-5400 m in depth) north of the Hess Deep depression. The Intrarift ridge represents, an outcrop of recent (1 m.y.) crustal and subcrustal material created at the axis of the East Pacific Rise (EPR), and emplaced during the lithospheric extention responsible for the westward propagation of the Cocos-Nazca rift (Francheteau et al., 1990). The lithospheric block has undergone cataclastic deformation and was dislocated by tectonic activity...

Aspects of the geochemistry of dissolved and particulate Cd, Cu, Ni, Co, and Pb in the Dover Strait
Provedor de dados: 5
Autores: James, Rh; Statham, Pj; Morley, Nh; Burton, Jd.
Water column samples have been collected at six stations across the Dover Strait within the framework of the FluxManche programme every month for fifteen months and analyzed for particulate and dissolved trace metals. Important seasonal variations in trace metal distributions have been identified. Dissolved Cu and Ni exhibit similar behaviour in the Strait; while seasonal variation in their distribution may be determined by changes in freshwater input, additional processes including biological uptake and regeneration and benthic input probably perturb water column inventories. Consistently with the suggestion of other authors, Co and Mn in both the dissolved and particulate phase exhibit some degree of covariance; substantial increases in the concentration...

Autores: Bouloubassi, I; Saliot, A.
Surface sediments were collected in the Rhone delta, NW Mediterranean, at two seasons and analyzed for composition of non-aromatic hydrocarbons (NAH), long-chain linear alkylbenzenes (LAB) and polycyclic aromatic hydrocarbons (PAH) by GC and GC/MS following fractionation by normal phase HPLC. Concentrations varied from 21.2 to 166.7 mu/g for NAH, from 2097.9 to 9324.2 ng/g for total PAH and from 342.5 to 2713.0 ng/g for LAB. These levels are comparable to those reported for other coastal areas worldwide in the vicinity of important urban and industrial activities. Detailed analysis permitted identification of several contributions to the bulk sedimentary hydrocarbon mixture from fossil fuel related sources, pyrolytic processes, domestic wastes as well as...

At present, the majority of fisheries are monitored and regulated in areas which are delineated by arbitrary ICES boundaries which do not necessarily have logical or consistent relationships with biological processes or fish movements. The biogeographical identification of Channel stocks is, therefore, an important step towards developing a rational strategy for the management of their fisheries. This synthesis is based on the wide available knowledge which has not been yet entirely exploited with the purpose of stock identification, for 25 commercially important species in the Channel. In addition, principal technics for stock identification are reviewed likewise environmental characteristics of the Channel, which represent fundamental components in...

Le sédiment a un rôle important de réservoir et de régulateur dans l'océan. Comme son étude est fastidieuse, pendant longtemps peu d'expériences ont été menées à son sujet. Depuis quelques années seulement , on étudie le sédiment très sérieusement et son rôle apparait primordial dans l'explication de certains phénomènes biologiques et chimiques du milieu océanique. Mais les océanographes sont souvent confrontés au problème de conservation des échantillons : En effet , pour pouvoir étudier sur de longues périodes les matériaux prélevés , il faut les réfrigérer ou les congeler. Or les effets de ce conditionnement sur la qualité chimique du sédiment, et ses effets biologiques sont encore très mal connus faute d'avoir été étudiés. Le but de ce stage est...

In this paper, we suggest two causal non-ideal approximations of this ideal non-causal controller. These time-domain absorbing relations differ in whether or not one knows a dominant frequency of the incident wave train to be absorbed. Their performances are compared to the absorption efficiency of the low frequency asymptotic Sommerfeld relation. Preliminary results of this study were already presented in Maisondieu and al.

Deformation and mixing in any medium are controlled by its viscosity and elasticity. The present study provides preliminary information, at oceanic shear rates, on the viscosity and elasticity in the bulk phase of seawater. Thirty-two samples of seawater, obtained on cruises at four times of year in a meso-oligotrophic part of the Mediterranean, were measured for bulk-phase viscoelastic properties in an oscillating-shear Couette flow with measuring gap 0.5 mm, over shear rates gamma from 0.0021 to 0.286 s-1. Fifteen samples were obtained on a single cruise in the German Bight, North Sea, when Phaeocystis blooms were taking place, and these were similarly measured at gamma from 0.0021 to 0.973 s-1.

Marine crustacean farming: present status and perspectives
Provedor de dados: 5
Autores: Laubier, Annie; Laubier, Lucien.
For centuries, several species of prawns and crabs have been raised from wild-caught juveniles in coastal brackish-water fish ponds in various countries of south east Asia. The Indonesian "tambaks" are well known examples of such traditional practices. In western countries, since the turn of the century, advances of marine biology and fast increase of marine fisheries enabled the development of large-scale production and release of larval stages of American and European lobsters in a fruitless attempt to restock natural populations. After the Second World War, the increasing demand for crustaceans in United States and Japan was satisfied by opening new prawn fisheries all over the world. A major breakthrough was achieved with the development of hatchery...

Les modèles polynomiaux du premier, second et troisième ordre se sont avérés inadaptés. Le modèle de régression multilinéaire a été testé avec les variables concentrations en phosphate (PO4) et en nitrate (NO3).

Time and space scales of significant wave heights
Provedor de dados: 5
Autores: Tournadre, Jean.
This paper presents a study of the temporal and spatial variability of the significant wave height (H(s)) based on stationarity and correlation (spectral) analyses. A sea state is defined as a stationary state of a piecewise stationary stochastic random wave process. Rupture detection, i.e., detection of abrupt changes in H(s), is used to identify the stationary components of the wave process. A sea state is characterized by its energy (i.e., H(s)) and by its duration of stationarity (spatial analysis) and length of stationarity (temporal analysis). Intensive in situ measurements of H(s) and Geosat radar altimeter data are used to study the temporal and spatial H(s) scales at two locations, in the North Sea and in the equatorial Atlantic. The stationarity...

Electron microscopy showed a typical dinoflagellate ultrastructure, though with certain peculiarities, and the presence of an abundant associàted bacterial microflora free-living or bound to P. lima cells. A few intracellular (endosymbiotic or infectious) bacteria were also detected within P. lima cells. Double-staining with anti-OA antibody and DNA staining revealed the presence of OA mainly in peripheral cytoplasm. OA was not detected in extranuclear DNA, indicating that these bacteria do not contain the toxin. High-pressure liquid...

Nutrition azotée du phytoplancton dans les eaux brassées de la Manche occidentale
Provedor de dados: 5
Autores: Lhelguen, S; Madec, C; Lecorre, P.
Uptake of nitrogenous nutrients (NO3-, NO2-, NH4+ and urea) by phytoplankton was measured over an annual cycle at a coastal station in the well-mixed waters of the western English Channel. Seasonal changes of nitrogen uptake showed a single, but spread-out, maximum in summer. The phytoplankton took up the various forms of nitrogen simultaneously. Ammonium uptake accounted for 48% of the total nitrogen uptake and was quantitatively important from the beginning of spring until early autumn. Nitrate uptake was relatively less important (32% of total nitrogen uptake) though nitrate was the major component of available inorganic nitrogen. Nitrate uptake rates were comparable to those of ammonium in winter and spring, but were much lower than the latter in...

Production costs in french scallop farming
Provedor de dados: 5
Autores: Paquotte, Philippe; Fleury, Pierre-gildas.
(Not controled OCR) The French King scallop farming method (hatchery, intermediate culture in cages nnd sea-bed extensive ongrowing) has been developed since 1983. A multi-steps project analysis has been carried out to estimate the economic feasability of the rearing activity. Because there is no market for spat in France at the moment, the project concerns the whole production cycle from hatchery to harvest. The project is designed to supply 150 m.t. of maketable scallops, which is the expected French farmed production in the near future. The project analysis software developed by IFREMER provides the main financial criteria, i.e. internal rate of return, potential earning power, cash requirements and a breakdown of the production costs. The first...

L'idée qui prévaut dans l'opinion du public est la surexploitation de la mer. Or, seule une très faible partie de la biomasse marine est prélevée via les pêches et cultures marines. Traditionnellement appréciés pour leurs qualités nutritionnelles, les poissons représentent de surcroît une importante source de molécules dont les activités biologiques intéressent au plus haut point les industries pharmaceutiques et cosmétiques La part de ces molécules marines, comparée aux matières premières d'origine animale terrestre, bien qu'encore très minoritaire, est appelée à connaître une croissance forte et rapide.

The dragonet Callionymus lyra, a target species used for evaluation of biological effects of chemical contaminants on French coasts
Provedor de dados: 5
Autores: Burgeot, Thierry; Bocquene, Gilles; Truquet, Philippe; Le Dean, Loic; Poulard, Jean-charles; Dorel, Didier; Souplet, Arnauld; Galgani, Francois.
An oceanographic cruise in 1991 along the English Channel and Atlantic coasts of France indicated the value of dragonet Callionymus lyra Linnaeus, 1758 as a target species for monitoring biological effects. Ethoxyresorufin-O-deethylase measurements in this species provided a first assessment of the effects of hydrocarbons (PCB, PAH, dioxins) on the marine environment. The specific behavior of dragonet was defined by biochemical characterization. Biological data were obtained during 3 additional oceanographic cruises to study changes in the abundance and distribution of the species in the English Channel and the Bay of Biscay. This first assessment, carried out in the context of the National Observation Network, indicated that pollutants do not have...

Sediment transport pathways in the eastern english-channel
Provedor de dados: 5
Autores: Grochowski, Ntl; Collins, Mb; Boxall, Sr; Salomon, Jc; Breton, M; Lafite, R.
Sand transport pathways are predicted, by combining outputs from an hydrodynamic numerical model with empirical sediment transport formulae. Tidal simulations, combined with various wind conditions, are compared with patterns presented in the literature. Results show that tides determine the long-term transport pattern in the area; this consists mainly of an ebb-dominated (North Sea towards Channel) mid-Strait region and flood-dominated pathways along the coastlines, which narrow towards the (Dover) Strait. Localised transport paths are identified; these are believed to be responsible partially for the presence of large sandbanks. Superimposed SW and NE wind activity overwhelms the tidally-induced pattern; this occurs infrequently and long-term pattern is...

Computed residual flow through the Dover Strait
Provedor de dados: 5
Autores: Salomon, Jean-claude; Breton, Marguerite; Guegueniat, Pierre.
A two-dimensional numerical model was used for the empirical deduction of a mathematical expression of water flow through the Dover Strait, for all conditions of tide, wind and ocean slope.  The theoretical results were correlated with sea measurements of radioactive tracers discharged at La Hague cape.  Nine actual years (1983-1991) were then examined, determining an average annual flow of 114000 mas-1 with a very high monthly variability, but with little difference from one year to the next.  These residual currents being highly sensitive to weather conditions, the mildness of the past few years has occasioned a decrease in fluxes towards the North Sea

Nonlinear friction effect in air-pressure forcing of the flow-through the strait of gibraltar
Provedor de dados: 5
Autores: Malacic, V.
The simple analytical two-strait and two-basin model built by (Candela et al., 1989), which well describes the barotropic flow through the Strait of Gibraltar forced by homogeneous fields of oscillating atmospheric pressure over the Eastern and Western Mediterranean, was improved by allowing the coefficient of linear bottom friction lambda to be frequency-dependent. The coefficient lambda is here proportional to the magnitude of the volume flow through the Strait of Gibraltar, and therefore increases with the frequency at very low frequencies, starting from zero. After reaching the extreme, which was tuned to be close to the value of frequency-independent lambda, the coefficient slowly decreases with frequency. Both approaches, with frequency-dependent and...

Selecting flat oysters, Ostrea edulis, for survival against the parasite Bonamia ostreae : assessment of the resistance of a first selected generation
Provedor de dados: 5
Autores: Martin, Anne-genevieve; Gerard, Andre; Cochennec, Nathalie; Langlade, Aime.
In 1989, a selected strain of flat oyster. Ostrea edulis, was produced from breeders that survived Bonamia ostreae and that were over selected by injection of purified parasites. This generation (G 1) was compared to native oysters which had settled during the same year. After a growing period of 21 months,  the oysters were tested according to three procedures: exposure to natural infection in an intertidal area, maintenance at the laboratory in tanks near heavily infested oysters, injection of parasites. The test lasted 7 months. In each procedure, oysters of the first generation (G1) showed a better survival rate than control oysters (72 to 94% versus 48 to 66%). On the other hand, the highest mortalities were observed among injected oysters (G1 and...

Hydrobiologie d'un écosystème conchylicole : le Pertuis Breton (17)
Provedor de dados: 5
Autores: Barille, Anne-laure.
La Baie de l'Aiguillon fut le berceau de la conchyliculture: les premiers parcs à moules furent établis au XIII""'· siècle par un irlandais P. Walton, naufragé en 1235 prés du port d'Esnande. C'est à lui que l'on attribut l'invention des bouchots. L'élevage traditionnel sur bouchot, initialement implanté à l'intérieur de la Baie de l'Aiguillon, a entraîné un tel envasement, que la culture des moules y est devenue impraticable. Les mytiliculteurs ont du installer leur bouchot à la sortie de la baie. Cette culture représente 20 000 tonnes; ce qui fait . du Pertuis Breton le plus important secteur de production mytilicole de la façade Atlantique. Cet élevage traditionnel occupe actuellement tous les sites exploitables, il faut donc conquérir de nouveaux...

Measurements of dissolved and particulate Cd, Co, Cu, Fe, Mn, Ni, Pb and Zn have been made on a regular basis over a fifteen month period at stations across the Strait of Dover, as a part of the Fluxmanche programme. These measurements have been integrated with data on fluxes of water and suspended particulate matter also obtained within the Fluxmanche programme to provide estimates of fluxes of these elements into the southern North Sea. For Fe, Mn, and Pb, particulate fluxes are greater than dissolved fluxes, whilst the reverse is true for Cd, Cu and Ni. Significant daily changes in magnitude of the modelled fluxes of water through the Strait when combined with averaged metal concentrations over longer timescales, result in large changes of fluxes of...

A three-dimensional, primitive equation, ocean general circulation model is used to study the response of the Gulf of Mexico to Hurricane Camille (1969). The free-surface dynamics and the mixed-layer features are included in the model. The numerical model incorporates the realistic coastline and bottom topography. The sigma coordinate model has eighteen levels in the vertical and 0.2-degrees x 0.2-degrees horizontal resolution for the entire gulf. The study focuses on nonlinear interaction between hurricane induced currents and the Loop Current. The numerical simulations show that there is a strong nonlinear interaction between the hurricane and the Loop Current in the southern and central parts of the eastern gulf. The surface currents due to nonlinear...

A note on progress in the bioeconomic modelling of fishing activity in the North Sea
Provedor de dados: 5
Autores: Catanzano, Joseph; Cunningham, S.
Over the relatively recent past, bioeconomic modelling has advanced by  integrating major theoretical and analytical progress made in both economic and biological modelling. The movements from static towards dynamic models and from global towards analytical models were the first steps in this advance. More recently, research has turned towards veritable optimisation models incorporating risk, asymmetrical information, and chaotic and multiple equilibria. Attempts to validate such models have been based on case studies of more and more homogenous fisheries (jesmall numbers of stocks and exploitation systems) so that the objective function is quite explicit and limited. This change of emphasis has occurred however without a re-consideration of the aim of the...

The deep-water benthos (115-2100 m) was sampled in the Atlantic-Mediterranean exchange area (Balgim cruise, N.O. Cryos: lberian-Moroccan Gulf, Strait of Gibraltar, Alboran Sea). The species richness of the bryozoan fauna (146 spp.) showed a marked between-site variability. Peaks of species richness occurred on both sides and in the Strait of Gibraltar under various conditions of temperature and salinity. 'rhe common features of the corresponding sites were the abundance of suitable substrates and the presence of currents facilitating supply of food and propagules. In the Alboran Sea, the species richness decreased with depth more rapidly than in the Atlantic and the depth distribution of several deep-water species showed an upward shift. There is an...

Vitellogenin (VTG) was isolated from the haemolymph of Penaeus vannamei by a three step procedure including ultracentrifugation, gel filtration and ion exchange chromatography. VTG was used to raise polyclonal antibodies that were purified by ion exchange chromatography. A two step competitive assay was developed in which VTG could be quantitated by its capacity to inhibit the binding of antibody to the VTG previously adsorbed onto a solid phase. Sensitivity from equilibrium and from non-equilibrium assays was 41 and 2.3 ng/ml respectively. Estimates of within-assay and between-assay variabilities of standard curves were 4.2 and 9.6% respectively.

Benthic carbon budget for the bay of saint-brieuc (western channel) - application of inverse method
Provedor de dados: 5
Autores: Chardy, Pierre; Gros, Philippe; Mercier, Herle; Monbet, Yves.
A steady-state energy flow model is proposed for the benthic fine sand community of the Bay of Saint-Brieuc. The main objective is to assess the relative importance of benthic processes associated with the carbon cycle in an eutrophicated bay. Available data include biomass estimates of the major trophic groups and measurements of the most critical fluxes : particulate organic carbon sedimentation, community respiration, microbial production. A balanced annual carbon budget is estimated using an inverse method, particularly appropriate in food web research where the number of unknowns is far higher than the number of independent observations. The method offers the possibility of taking dynamical constraints into account, by introducing global flow...

Elles ont été soumises sur trois périodes de l'année à trois conditions différentes de renouvellement d'eau : quotidien, biquotidien ou apport continu, le témoin étant caractérisé par l'absence de tout renouvellement d'eau. Les résultats permettent de dégager un ensemble de remarques sur l'état physiologique, sur l'activité métabolique des...

Modelling growth and feeding of the Japanese oyster Crassostrea gigas in Marennes-Oleron Bay (France)
Provedor de dados: 5
Autores: Raillard, Olivier; Deslous Paoli, Jean-marc; Heral, Maurice; Razet, Daniel.
A model simulating growth and feeding is presented for Crassostrea gigas and incorporates such physiological processes as filtration rate, pseudo-faeces production and ingestion, oxygen consumption and spawning. The only state variable is flesh weight. This model is designed to incorporate the effects of quantity and quality of food, temperature and oyster dry weight. Comparison of simulation outputs with real data showed that the model closely simulated the seasonal changes in weight over a two-year sample interval. This simulation confirms that oyster growth in Marennes-Oleron Bay is strongly regulated by the non-organic concentration in the seston. This latter factor dilutes the potential food for oyster and causes a large amount of food rejection in...

Analyse et modelisation des parametres d'exploitation du stock de coquilles saint-jacques (pecten maximus, l.) en baie de saint-brieuc (manche ouest, france).
Provedor de dados: 5
Autores: Fifas, Spyros.
The population dynamics is developed upon data on the age-composition of catches collected since 1974 by a sampling technic at two levels (fishing day, vessel). A temporally stratified sampling is carried out. A cohort analysis is realized through these data ; assumptions for the coefficients of natural and indirect fishing mortality are set up. Catchability models for all age groups are fitted. Catchability of the most abundant age groups (2 and 3) is an increasing function of their abundance and of the fishing fleet mean horse power. These functions present a maximum asymptotical value. Their adequation is explained by the adaptations of dredges and by the population sedentary life allowing the concentration of fishing fleet on the most abundant areas. A...

Inertial Resonance Induced by an Oceanic Jet
Provedor de dados: 5
Autores: Klein, Patrice; Treguier, Anne-marie.
The dynamics of the mixed layer in the presence of an embedded geostrophic jet has been investigated using a simple 1 1/2-layer model and a two-dimensional primitive equation model. The jet vorticity induces a spatial variability of the wind-driven inertial motions that can have some important consequences on the mixed-layer dynamics. With a steady wind stress parallel to the front. the main effect is the generation of steady upwellings and downwellings due to the divergence of the mean Ekman drift (as reported by Niiler). With a cross-front wind, however, a dramatic exponential amplification of the inertial oscillations caused by an inertial resonance mechanism is found: this mechanism can increase the inertial waves amplitude by a factor up to 10 within...

Ce mouvement d'ouverture s'observe aussi au niveau des instances institutionnelles chargées de la gestion du secteur. Ainsi le nouveau cadre de la Politique Commune de la pêche même s'il recherche toujours un équilibre entre ressource et exploitation, s'adjoint de façon explicite un objectif socio-économique de pérennisation des activités, qui des lors que l'on prend en compte les aspects sociaux, fait apparaître au coté des questions d'efficacité, celle de léquité. Les nouveaux axes de cette Politique Commune Européenne sont définis en trois points:  -la...

Rapport relatif au projet d'étude en génotoxicité de l'environnement marin
Provedor de dados: 5
Autores: Vincent, Francoise.
La toxicologie génétique a pour but d'apprécier le mode d'action d'un agent chimique ou physique sur le matériel héréditaire et d'en mesurer les conséquences en terme de mutations et de cancers (Moustacchi, 1983). Elle est née du besoin d'évaluer et de prévenir les risques génétiques potentiels inhérents au développement et à l'emploi massif des produits chimiques. Cette appréciation qualitative et quantitative des risques génétiques est fondée sur l'existence d'une batterie de tests et a abouti à une législation (Lohman et al., 1992; Scott et al., 1991; CEE, 1992; OCDE, 1987). L'élaboration d'un projet de recherches en toxicologie génétique à l'IFREMER s'inscrit dans la suite logique des travaux réalisés au laboratoire d'écotoxicologie sur les effets...

Provedor de dados: 5
Autores: Rathier, I.
The stock of Lambi, Strombus gigas (gastropod: strombidae), coastal benthic resource, has been exploited artisanally since the prehistoric period in Martinique. Nowadays, three lines of work exploit the species: free diving, nets (since the middle of the century) and scuba diving since 1985. This report presents the activity of each line of work, surveyed directly from 1986 to 1987: fishing zones and resource allocation, production, effort and performance, detail of catches (by length). The socio economic characteristics of the lambi fishermen are studied. The significant production of leisure fishing is also estimated. The decrease in the production and performance, as well as the lowering of the size of the first catch for about thirty years show that...

Autores: Omnes, Marie-helene; Temey, Yann; Daniel, Jean-yves; Nicolas, Jean-louis.
Bacterial infections have been suspected to be one cause of variable success in the incubation of turbot (Scophthalmus maximus) eggs. The assessment of bacterial flora (bacterial environment) associated with ova, sperm and developing eggs was conducted just at stripping gametes and during incubation. Gametes were collected in sterile conditions before fertilization. Eggs were held in an open-circulation 401 incubator, at 13 degree C during 6 days until hatching. Samples of those were collected every day. They were rinsed several times with sterile seawater, counted and grown. Viable counts of bacteria were determined on two media, Zobell and TCBS agar. Epibiotic bacteria on the surface of the eggs and impact on the chorion were observed at scanning...

Autores: Legiot, Anne-dominique; Le Mao, Patrick; Convenant, Aliette; Penot, Julia.
La conductance-métrie est une nouvelle méthode d'analyse bactériologique. Elle est utilisée dans de nombreux produits alimentaires pour la détection des salmonelles. La réponse (absence ou présence présumée) est donnée plus rapidement par cette technique que par les techniques classiques, permettant ainsi de diminuer le risque sanitaire lié à ce pathogène. La méthode a été testée sur différents coquillages artificiellement contaminés par les souches de salmonelles les plus fréquemment retrouvées dans le milieu naturel. Les résultats obtenus indiquent qu'elle pourrait convenir pour le milieu marin. Toutefois des tests sur coquillages naturellement contaminés sont nécessaires pour établir sa fiabilité avant son application en routine.

An ELISA technique for rapid diagnosis of vibriosis in sea bass Dicentrarchus labrax
Provedor de dados: 5
Autores: Romestand, B; Dragesco, A; Breuil, Gilles; Coste, F; Bouix, G.
Three batches of rabbits were immunized against 2 strains of Vibrio anguillarum (Va V 62 and Va V 408), which cause vibriosis in sea bass Dicentrarchus labrax (L. 1758) Serranidae. Homologous and heterologous reactions were obtained against these Vibrio strains and other bacteria using an improved indirect ELISA technique. Antibody and antigen titrations revealed high immunogenecity (high antibody titers for the antisera) of the 2 Vibrio strains. They correspond to serotype I and show close affinity. The specificity and sensitivity of 1 selected antiserum were tested on brain extracts from healthy sea bass and those infected artificially with V. anguillarum serotypes I and III. Preliminary results confirm the reliability of the technique and warrant its...

Among the marine molluscs, Pacifie oyster, Crassostrea gigas, is actually the most reared specie in the world. Noticely in France, where it was imported between 1960 and 1970, and replaced by Portuguese oyster, Crassostrea angulata, which specie was decimated during this period because of iridoviruses. Uncontroled introductions of new species may however be hazardous. Indeed, they might be responsible for the appearance and the dissemination of new diseases of bivalve molluscs in importing country. In addition to these observations, the quasi monobreeding of Pacific oyster in France enhances the necessity to develop research concerning the diagnosis of pathologies affecting this specie, namely the diagnosis of viral diseases. Several families of viruses...

Modeling Japanese oyster physiological processes under natural tidal variation in suspended particulate matter
Provedor de dados: 5
Autores: Barille, Laurent; Prou, Jean.
Feeding and growth of the Japanese oyster Crassostrea gigas is simulated by a deterministic model. However, physiological processes, estimated by statistical relationships, have not been tested under extreme environmental conditions such as high level of suspended particulate matter. Ecophysiological experiments were therefore conducted in situ in the Bay of Marennes-Oléron during a spring and neap tide cycle in May 1991, to get a better representation of 2 important components of the energy budget of the Japanese oyster: clearance rate and selection efficiency. The relationships previously established by Raillard et al. (1993) are re-evaluated by integrating the action of high seston load, typical of tidal effect within estuaries, on the physiological...

The last global synthesis of the evolution of the Indian ocean which satisfactorily describes the kinematics of the five major plates, up to the initial stages, dates back to Norton and Sclater [1979]. Although the most recent phases of evolution have been largely detailed, in particular in the proximity of the triple junction, the initial stages of evolution have been generally described by models quite speculative and generally only constrained by pairs of plates.  The recentmost gravity data based on the altimetric satellites SEASAT, GEOSAT and ERS1 [Sandwell and Smith, 1992] give an homogenoeus image of sea-floor topography. These data, declassified to the south of 30°S, reveal previously unknowkn features of the sea-floor fabric and allow to further...

Autores: Aminot, Alain; Guillaud, Jean-francois; Andrieux, Francoise.
The Bay of Seine receives the French river with the highest nutrient concentrations, especially phosphorus. Dissolved (phosphate) and particulate phosphorus fluxes have been determined from fortnightly serial data collected by the Port Autonome de Rouen. These determinants exhibit behaviour opposite to that of the river flow: phosphate concentration decreases hyperbolically and particulate phosphorus increases linearily. An approach based on the rate of domestic effluent treatment agrees well (20%) with the measured phosphate flux. The determination of the main particulate phosphorus forms (adsorbed, apatite, non-apatite inorganic, organic) was undertaken over the whole estuarine salinity range. The speciation of particulate phosphorus exhibits a great...

Within the framework of the European Fluxmanche programme, 92 samplings of suspended particulate matter were collected during eight cruises through the Dover Strait. The mean concentrations obtained for Al (44.3 mg/g), Fe (27.4 mg/g) and Ca (110 mg/g) are comparable to those obtained by Nolting and Eisma in January 1980. However, the concentrations of Mn (0.585 mg/g) Ti (3.14 mg/g) and V (0.225 mg/g) are twice as large. An important gradient of concentration is observed between the coastal and offshore waters, reflecting coastal erosion and human activities. Detailed examination of the contents of the major elements indicates that these remain practically constant in the particulate matter during a tidal cycle. On the other hand, the concentrations of...

During the STARMER programme the submersibles Nautile and Shinkai-6500 carried out 14 dives on the NS segment of the North Fiji Basin Ridge (Station 14 at 18-degrees-50 S). From structural point of view, two types of morphology appear: in the northern part, the axis is not tectonically well expressed hut the hydrothermal activity is important. in the southern part, a graben structure 150 m wide exists, with both a.fossil and a present-day hydrothermal activity. The station 14 shows a morphostructural variability of the spreading axis which can be related to the different stages of the volcanic and tectonic cycles. Another station explored at 19-degrees-S, a few kilometres to the south, confirms the fact that different stages of tectonic and magmatic...

Autores: Moguedet, Philippe; Mahe, Jean-claude.
The late winter distributions of the American plaice (Hippoglossoides platessoides) in St. Pierre Bank (NAFO Subdiv. 3Ps) during the period 1978–90 were analyzed using catchesper- 30-min-tow data obtained during the French groundfish surveys which have been conducted annually in February–March. Water temperatures from surface to bottom recorded at the end of each trawling operation were used along with temperature recordings from a standard hydrographic transect. Largest temperature fluctuations occurred in the two upper depth ranges (0–99 and 100–199 m) and were assessed to be due to the great influence of the Labrador Current. Generally, American plaice was well represented in the Halibut Channel. During cold winters (1982, 1985–87, 1989 and 1990),...

Autores: Kawahata, H; Ishizuka, T.
Biogenic siliceous and calcareous sediments were drilled at sites 677 and 678 on the flank of Costa Rica Rift in the Panama basin. We analysed DCAA (dissolved combined amino acids) and DFAA (dissolved free amino acids) in the interstitial waters as well as THAA (total hydrolyzable amino acids) in the sediments in order to evaluate the relationship between THAA, DCAA and DFAA. Comparison of the THAA in the sediments and in marine settling particulate matter (Ittekkot et al., 1984 b) showed that the concentration of non-protein amino acids (e. g., beta-alanine, gamma-aminobutyric acid, and ornithine) was much higher in the sediments and that the neutral amino acid fraction was depleted in the sediments. These results, together with the organic carbon...

Modelisation du cycle de dégradation bactérienne de la matuère organique - Application à la zone de Turbidite maximale de l'estuaire de la Loire
Provedor de dados: 5
Autores: Maurice, Laurence.
Depuis plusieurs années, on observe dans l'estuaire de la Loire, une forte mortalité de mulets au cours de leur avalaison en septembre. Ce problème est directement lié à la présence d'une zone anoxique. Comme dans d'autres estuaires européens, les minima d'oxygène dissous correspondent à la zone de turbidité maximale. En Loire, en période d'étiage fort, cette zone peut remonter jusqu'à la commune de Nantes. Pour pallier à cette problématique, l'IFREMER, à la demande du Port Autonome de Nantes Saint Nazaire, a développé plusieurs outils numériques. Un modéle d'oxygène dissous a été mis en oeuvre afin de reproduire l'évolution des teneurs en oxygène dissous le long de l'estuaire. Les premiers résultats ont souligné l'importance, dans la demande en oxygène...

Multiple Equilibria for Cross-Gyre Flow between Subpolar and Subtropical Gyres
Provedor de dados: 5
Autores: Schopp, Richard.
A simple Sverdrup-type two-layer model that allows the outcropping of isopycnals is forced by wind stress, is completed with a frictional western boundary layer, and is investigated along the zero wind-stress curl line separating the subpolar gyre from the subtropical gyre. The study focuses on the different cross-gyre flow patterns. Intermediate length-scale dynamics, which is able to take the dispersion of Rossby waves and the steepening of isopycnals into account, is used to analyze the evolution of these cross-gyre currents. In particular, these transients show that the solution, which exhibits an arrested Rossby wave, is unstable in the western part of the basin. Nevertheless, this solution is able to evolve to other more stable solutions present in...

Relations biométriques chez l'araignée de mer Maja squinado : longueur de référence, distinction juvénile-adulte, taille-poids.
Provedor de dados: 5
Autores: Le Foll, Didier; Latrouite, Daniel; Noel, Philippe.
For the analysis of spider crab populations it is necessary to split the size composition by sex and between age groups, and to convert length to weight. In some cases different length measurements need to be correlated in order to compare the results from different authors. Morphometricaly it is easy to use the abdominal flap to distinguish between male and female, and between immature and adult females, but for immature and adult males it is necessary to use Somertons method to analyse the relation between carapace length and claw width. The relation between carapace length and weight is normally established at moult stage 4, and it obtained separately for males, females, immature and adults spider crabs. When measuring carapace length the present length...

Autores: Paulmier, Gerard.
For several years the fishermen of the West Indies have directed their activities towards new fishing grounds, notably the bathyales zones adjacent to island plateaux up to approximately 1000 metres in depth. Explorations earned out since 1989 have shown that diverse crustacean populations could be exploited. However, populations and exploitable stocks arc not well known. The use of crustaceans traps as a fishing technique permits the capture of shellfish, shrimps and prawns of which at least six species could have commercial interest. The main objective of this work is do draw up an inventory of the principal commercial species as well as the accompanying species belonging to the subordres Decapoda macrura, anomura, brachyura, and to the orders Isopoda...

En mer du Nord, il a été montré que la prédation qu'exercent entre elles les espèces exploitées constitue un des facteurs majeurs qu'il faut prendre en compte pour analyser les effets de différents régimes de gestion des ressources halieutiques. Pour cette zone, les biomasses de poissons consommées à l'intérieur du système par les principaux prédateurs sont équivalentes à celles qui y sont pêchées.   En particulier le merlan (Merlangius merlangus) y a été reconnu comme un prédateur majeur de juvéniles des autres espèces, au point que pour la modélisation multispécifique des pêcheries les valeurs de mortalité naturelle pour les poissons les plus jeunes sont fonction de la biomasse du stock de merlan.

Increased offshore advection of migratory neritic plankton may occur by the pathway of nearshore submarine canyons. The nocturnal distribution of migratory bentho-hyponeustonic crustacea was investigated in the axis and on both sides of three submarine canyons, over the continental shelf and slope of the northwestern Mediterranean. The three canyons arc frequently exposed to strong northerly and northwesterly winds blowing seaward. A horizontal surface haul and a vertical haul from bottom to surface were successively achieved with an OMORI plankton net over each depth, from the isobath 50 m to more than 1000 m, in the middle of the night. The Mysidacea Anchialina agilis, Haplostylus lobatus, Siriella clausii, Siriella norvegica and Leptomysis gracilis, and...

Autores: Prandle, D.
Contaminants from the Channel flow through the Dover Strait into the North Sea where they represent a significant fraction of the enhanced concentrations observed along the continental coast. Despite numerous previous investigations, the magnitude of this net flow and its dependency on various forcing factors remain uncertain. The new UK H.F. Radar system, OSCR (Ocean Surface Current Radar) developed for measuring nearshore surface currents offers a clear opportunity of establishing the magnitude and nature of this flow. Starting in July 1990, H.F. Radar observations were made in the Dover Strait for five months from the French coast overlapping (for two months) with five months from the English coast. These measurements involved fully-automised monitoring...

Eddies in the greenland sea observed from infrared and visible satellite radiometry
Provedor de dados: 5
Autores: Mitchelsonjacob, G.
The complex dynamical structure of the Greenland Sea and its associated mesoscale processes can be observed in satellite imagery. Intense temperature gradients, e. g. between the East Greenland Current and the West Spitsbergen Current, are detected by infrared radiometry, as is the mesoscale activity associated with these fronts. Ocean colour data showing variations in phytoplankton biomass depict the underlying physical processes of the Greenland Sea. The variability in spatial scales of these features can be estimated from radiometry data. The highest pigment concentrations (&gt; 20 mug l-1) are observed in the colder water close to the marginal ice zone (MIZ) which is clearly visible in the near-infrared data.

A steady-state model of PCB accumulation in dab food web
Provedor de dados: 5
Autores: Loizeau, Veronique; Menesguen, Alain.
A five-compartment steady-state food web model is proposed for the benthic food web leading to the dab. Three exposure pathways are considered in the description of accumulation by benthic animals: ingestion of particulate contaminants associated with either sediment or phytoplankton, and respiratory uptake of free dissolved contaminant in overlaying water. Application of the model to a simple food web in the Bay of Seine (Eastern Channel) indicates that : a) feeding is the principal route of contamination, especially for PCB which have more than four chlorine atoms in the molecule ; b) excretion and growth rates, phytoplankton lipid fraction and organic carbon content of sediment are the parameters which mostly determine the chemical bioaccumulation in...

Mediterranean sapropel formation, dynamic and climatic viewpoints
Provedor de dados: 5
Autores: Bethoux, Jp.
Sapropels, i. e. discrete, black and organic-rich layers sedimented in the Eastern basin in anoxic conditions, constitute record, over the past 500,000 years, of eleven particular interactions between marine circulation and biology during glacial as well as temperate climates. Considering climatic and dynamic aspects, we argue that this formation is preconditioned by the stoppage of dense water formation in the Adriatic Sea, following sea-level and/or freshwater input changes. In this case, oxygenation of eastern deep water depends solely on the dense water formation in the South Aegean Sea, a process modified by episodic freshwater inputs. This scheme explains correlations between sapropel events and the strong African monsoons responsible for Nile river...

This study deals with comparison of morphology and in situ behaviour of three Alvinocarididae species from the Snake Pit hydrothermal area (mid-Atlantic ridge), explored during the Hydrosnake cruise (1988). Spatial distribution on the site is described and illustrated for the three species. Rimicaris exoculara highly predominates. Modifications, apparently more morphological than functional, allowed adaptation to an environment characterised by extreme physico-chemical conditions and richness in bacteria. This species has developed a culture of bacteria on its mouthparts and under the carapace to complement nutrient input drawn from bacterial production from the surface of active chimneys. Rimicaris exoculata aggregates on active diffusers and affect the...

A 3.5 KHz high-resolution seismic survey carried out on the West-Riffian continental shelf, between Cap Spartel and Rabat, has shown that the morphostructural lineaments already identified on the continent, mainly within the South-Riffian western basin and its margins, extends towards the sea, on the continental shelf. These structures are related to stepped anticlinal flexures with a large curvature radius. The paleozoic acoustic substratum to the south and the cenozoic to the north are both characterised by a succession of abrupt erosion surfaces whose relatively constant bathymetric position could be attributed to paleoshorelines. We have also shown that the river mouth of Oued Sebou has changed position in the course of the Quaternary, under the...

A sampling strategy and methodology for assessment and monitoring of Mediterranean small-scale fisheries
Provedor de dados: 5
Autores: Farrugio, Henri; Le Corre, Gildas.
In order to reach a quantitative assessment of the Mediterranean small-scale fisheries one of the main problems is to evaluate in space and time the elementary fishing efforts and yields of every component and their corresponding variations. These elements are essential for the evaluation of global production and fishing effort, the monitoring of which is of paramount interest for the study of the fisheries and exploited resource dynamics. This paper presents a methodology based on the statistical principles of so-called "stratified random sampling" which we have developed in an attempt to solve this problem. The collection of data is achieved in the field by a team of investigators which operates within a space-time stratification of the study area. The...

Use of a disjunctive kriging to model areas of high pelagic fish density in acoustic fisheries surveys
Provedor de dados: 5
Autores: Petitgas, Pierre.
Schooling fish may aggregate in very high densities covering very small areas. Thus the probability of hitting such high-density spots during a large-scale sampling is very low. The sampling fluctuations of the tail of the histogram are thought to be very significant. The stock biomass estimate and its precision rely greatly on how precisely the tail of the histogram can be sampled. In order to acquire elements for improving survey designs and abundance estimators wc study here the relation in space that the high values have with the other values. A disjunctive kriging approach is used. Different quantiles of the histogram are coded by indicators. The spatial structure of each indicator and its spatial covariation with the others are studied by computing...

During a survey at six stations in the Dover Strait, from July 1990 to November 1991, water samples were collected to measure : suspended sediment load and its organic content; particle characteristics; photosynthesis pigments; and heavy metals. In this contribution, particle measurements are interpreted in terms of hydrodynamical effects and seasonal evolution. Multi-modal grain size spectra are indicative of depth and cross-sectional variations, from die coastline to the central waters. Tidal variations, biological productivity and wind effects can be identified. Suspended particulate matter (SPM) components (determined using SEM, when combined with size spectra) illustrate hydrodynamical, geomorphological and biological effects on the composition of the...

Autores: Littaye-mariette, Anne; Bouget, Jean-francois.
Pour la quatrième année depuis 1989, des lots d'huîtres creuses calibrées sont réparties sur 10 sites ostréicoles de Bretagne Nord et Sud. L'objectif est de décrire les caractéristiques et les tendances de la croissance des huîtres sur les principaux bassins d'élevage. Par rapport aux années précédentes, la croissance des huîtres et en teneur en chair des coquillages ont été meilleures en 1992. Seulement 2 sites (Morlaix et Pénerf) démontrent une tendance inverse. L'infestation des coquilles par le ver Polydora est également en augmentation, notamment dans les estuaires. Les résultats d'élevage différent selon la configuration des sites ouverts (Cancale, Paimpol) et les sites enclavés (Aber Benoît, Pen Bé). La rade de Brest, intégrée pour la premiére fois...

Organisation spatio-temporelle des peuplements ichtyologiques dans deux lagunes côtières : au Portugal et en Guadeloupe
Provedor de dados: 5
Autores: Aliaume, C; Monteiro, C; Louis, M; Hoai, Tl; Lasserre, G.
Fish communities from two lagoon ecosystems, Ria Formosa (Portugal) and Grand Cul-de-Sac Marin (Guadeloupe), show interesting similarities of spatial and temporal organization. On the temporal scale, three community changes are observed in both systems, corresponding to massive arrivals and/or departures of migratory species. However, these migrations are more conspicuous in the Ria Formosa than in the Grand Cul-de-Sac Marin. On a spatial scale, the community structure is also largely determined by migratory species, whose abundance is a factor of homogenization. This is clearly observed in Ria Formosa, where the lagoon selection applies on a regional scale. Conversely, the community of sedentary fish identifies remarkable stations affected by chronic...

Plankton transfers and coastal front in the dover strait
Provedor de dados: 5
Autores: Brylinski, Jm; Aelbrecht, D.
Zooplankton and current studies were carried out in the coastal front of the Dover Strait. We show that the maintenance of both offshore and inshore planktonic communities is due to two coupled phenomena: 1) the residual drift of water differs in the upper and in the deeper waters; and 2) the vertical distribution of plankton differs for inshore and offshore species. In the frontal area, the coastal species remain in the lower water layer where the residual drift is landward. Conversely, the offshore species remain in the upper water layer where the residual drift is seaward.

Circulation of the cretan sea-water masses (eastern mediterranean-sea)
Provedor de dados: 5
Autores: Zodiatis, G.
The autumnal circulation of the Cretan Sea is discussed on the basis of CTD data from the POEM-3 cruise (autumn 1986). Analysis of the thermohaline and dynamic regimes of the basin revealed the existence of a large scale cyclonic gyre. In addition to the data, a numerical model was used to compute the steady-wind driven circulation pattern, taking into consideration the autumnal fields of water density. The resulting dynamic structure of the Cretan Sea waters differs from that of the other seasons. In the surface layer of the western Cretan Sea down to 100 m predominated a relatively brackish water layer of Black Sea origin. In the SE Cretan Sea, this water mass penetrated as far southeast as the Kasos Strait. During this season, the circulation in the...

La surveillance bactériologique de 1989 à 1992 du bassin de Marennes-Oléron et de la rive droite de la Gironde met en évidence la bonne qualité du milieu. Les dépassements de la norme (&gt;300 coliformes fécaux/100 g de chair et liquide intervalvaire) sont peu fréquents. Quelques pollutions sporadiques peuvent apparaître, le plus souvent en été, et sont liées au dysfonctionnement passager des systèmes d'assainissement (postes de relèvement, stations d'épuration) ou aux infiltrations d'eaux usées dans les réseaux pluviaux. L'application de la directive européenne de 1991 aurait une incidence limitée sur le classement des zones de production conchylicoles du bassin de Marennes-Oléron.

Thermal structure of the western indian-ocean during the southwest monsoon, 1983
Provedor de dados: 5
Autores: Sarma, Yv; Sarma, Mss; Rao, Lvg.
The thermal structure and the variability of heat content of the upper 400 m of the Western Indian Ocean were examined using the expendable bathythermograph (XBT) data collected onboard RV Sagar Kanya during July-August, 1983. Vertical displacement of the thermocline was found to be closely associated with the spatial changes in the heat content integrated to 300 m depth. Besides, the low heat content in the study region near the land boundaries was also due to the coastal upwelling along India and Somalia. The south central Arabian Sea appeared to be a warm region with higher heat content, while the cold regions were located essentially along the coasts of Somalia and India. In the south central Arabian Sea the heat was transferred vertically downwards...

The population of Pinctada margaritifera and Pinctada maculata lay eggs throughout the year. Temperature variations induce huge but asynchronous laying. Preferential periods of gonad maturity correspond to the season changings in both species. However. some differences between the two specics are noticed. Both species are protandric hermaphrodites. Female condition is unstable: a reversion to the male condition may be observed and is probably linked with stress. The average size for the first sexual maturation as weil as for sexual conversion are specified in P. margaritifera. The breeding conditions induce modifications in some reproductive cycle processes (maturation, sex-ratio). Some conditions suitable for reproduction may become unfavorable to...

Modélisation de l'écosystème de l'étang de Thau : rôles du sédiment et des huîtres cultivées sur le cycle de l'azote
Provedor de dados: 5
Autores: Bioteau, Hélène.
L'étang de Thau, sur la côte méditerranéenne française, est régulièrement soumis à des phénomènes anoxiques appelés "malaïgues". Ces phénomènes interviennent lors de baisses d'intensité du vent en été et sont principalement dus à l'accumulation dans le sédiment de rejets organiques provenant des cultures conchylicoles qui occupent 1/5 ème de la superficie de l'étang. Dans le but de lutter contre ces crises anoxiques, un programme de recherche appelé OXYTHAU a été lancé en 1991 et propose entre autres d'aborder la modélisation de l'écosystème de l'étang afin d'obtenir une vision synoptique du fonctionnement de ce dernier. Le modèle biologique présenté dans ce document simule ainsi le cycle de l'azote sur un an dans la colonne d'eau et le sédiment au niveau...

Alors que les recherches étaient jusqu'alors essentiellement biologiques en même temps que centrées sur la phase d'exploitation, l'histoire récente de l'halieutique témoigne d'une ouverture de ses problématiques scientifiques en direction de l'écologie et des sciences sociales. Tandis que l'ouverture vers l'écologie est fondée sur l'importance des processus hydrodynamiques dans la régulation des populations au niveau du recrutement, la prise en compte des comportements des pêcheurs conduit l'halieutique à évoluer vers l'analyse des interactions entre systèmes naturels et systèmes sociaux. Il s'en suit une remise en cause certains des paradigmes des méthodologies classiques d'évaluation de ce secteur. Conséquence de ces évolutions le concept de pêcherie...

Modeling of tidally-induced hydro-sedimentary processes in the coastal zone of the southern part of the dover strait
Provedor de dados: 5
Autores: Chapalain, G; Smaoui, H; Lepretre, A; Nguyen, Kd; Ouahsine, A; Tessier, B.
The present paper deals with the modelling of hydro-sedimentary processes in the coastal area near Cape Gris-Nez and Cape Blanc-Nez (Dover Strait). The modelling procedure consists in coupling different hydro-sedimentary process models with a high spatial resolution two-dimensional tidal flow model (Nguyen and Ouahsine, 1992). The sediment transport models used include two semi-empirical models based on a dimensionless analysis and energetic concepts (Ackers and White, 1973; Engelund and Hansen, 1967), and a more heuristic cu (concentration times velocity) model (van Rijn, 1984 a; b). All these models are applied to predict instantaneous and tidally-integrated sediment transports in the area under investigation.

Genomic DNA cloning of rickettsia-like organisms (RLO) of Saint-Jacques scallop Pecten maximus : evaluation of prokaryote diagnosis by hybridization with a non-isotopically labelled probe and by polymerase chain reaction
Provedor de dados: 5
Autores: Kellner-cousin, Kristell; Le Gall, G; Despres, Béatrice; Kaghad, M; Legoux, P; Shire, D; Mialhe, Eric.
Genomic DNA fragments of a rickettsia-like organism (RLO) of Saint-Jacques scallop, Pecten maximus, were extracted from purified RLO and cloned. A DNA sequence of 1500 bp taken from one of the sequenced clones was coupled to horseradish peroxidase and the resulting probe was assayed for the diagnosis of RLO by nucleic acid hybridization. The specificity of the probe for RLO DNA was established from its lack of hybridization with scallop DNA. The sensitivity limit of the probe detected by enhanced chemiluminescence was determined to be around 500 ng of total RLO nucleic acids, equivalent to about 2.5 X 106 copies of RLO DNA. A pair of polymerase chain reaction (PCR) primers were synthesized that amplified a 1300 bp segment of the 1500 bp RLO fragment. After...

Quality in aquaculture : a major issue in international competition
Provedor de dados: 5
Autores: Paquotte, Philippe.
Despite its youth, aquaculture is an activity which is definitely subjected to the rules of international trade. The dependence on natural conditions is the first cause for the existence of national or regional comparative advantages. But both economic and institutional environment have to be taken into account when listing the assets or constraints of a location for implementing aquaculture. Because of little possibilities of economies of scale and because of fast technological spread in aquaculture, it is very difficult to obtain a price competitiveness based on industrial size of the activity or on technological advance. That is the reason why aquaculture has to look for other sources of competitiveness like the quality or the control of the market...

Why carrying capacity models are useful tools for management of bivalve molluscs culture
Provedor de dados: 5
Autores: Heral, Maurice.
In areas where oyster or mussel culture is very intensive, declines of growth rate and decreases of survival rate have occurred. For these reasons, plans have been proposed to regulate the cultivated biomasses in order to fit the carrying capacity of the different ecosystems (Heral et al 1990; Heral, 1991). In areas where new aquaculture of molluscs is beginning, oyster or mussel farmers need to know how large the extension of the culture could be and what the maximal densities should be in order to obtain the maximum economic benefit. Furthermore, as mollusc cultures are developed in coastal areas, they are very susceptible to changes in environmental conditions that can modify trophic relationships, or directly reduce growth rate, physiological...

Hydrographic (0-1000 dbar) and direct current measurements (0-600 dbar) along 165-degrees-E (20-degrees-S-10-degrees-N) between January 1984 and July 1991 are used to investigate the mean circulation and its relationships with the distributions of salinity and potential vorticity on isopycnal surfaces. Less well documented mean sections along 142-degrees-E and 137-degrees-E are used to complement the 165-degrees-E analysis. The Equatorial Undercurrent is centered on the equator at 165-degrees-E and on 0.5-degrees-N at 142-degrees-E. No variation in its transport (15.0 x 10(6) m3 s-1) is found between those longitudes.

Sea-level variability and semiannual rossby waves in the South-Atlantic subtropical gyre
Provedor de dados: 5
Autores: Le Traon, Pierre-yves; Minster, Jf.
We derived the sea level variability in the South Atlantic subtropical gyre between 15-degrees and 35-degrees-S from 2 years of the Geosat exact repeat mission altimeter data. On the mesoscale, along-track wavenumber spectra are those of nonlinear dynamics with a steeper slope and stronger energy along the eastern boundary. Frequency/wavenumber spectra reveal a significant semiannual signal at a wavelength of about 500 km. West of the Walvis ridge (5-degrees-E), this signal appears to correspond to semiannual Rossby waves of 2- to 3-cm amplitude, propagating westward at 3 cm s-1, and showing latitude refraction effects. The pattern is very similar to that of annual Rossby waves as modeled by Reason et al. (1987). These waves are probably related to the...

Gross sedimentation-rates in the north sea-baltic sea transition - effects of stratification, wind energy-transfer, and resuspension
Provedor de dados: 5
Autores: Lundhansen, Lc; Pejrup, M; Valeur, J; Jensen, A.
Gross sedimentation rates (GSR) were measured using sediment traps placed at different levels above die seabed (0.3, 0.5, 0.8, 1.0, 2.0, 4.0, 6.0, 8.0, 10.0 m) at a water depth of 17 m. The traps were deployed for 1.25 year. The study was carried out at a location in die semi-enclosed Aarhus Bay, in the southwestern part of the Kattegat, which forms the transitional zone between the highly saline (32-34) North Sea and the less saline (15-20) Baltic Sea. Hydrographic conditions in the Aarhus Bay are dominated by significant changes in salinity during the year, and the water column was stratified for 80 % of the time. High GSR values were recorded near the seabed with a mean of 114.8 (g m-2 day-1) at 0.3 m above the seabed, whereas low GSR values were...

Modeling the nitrogen cycle in the channel : a first approach
Provedor de dados: 5
Autores: Hoch, Thierry; Menesguen, Alain; Bentley, D.
A simple model of the nitrogen cycle in the Channel is proposed. Based on the long-term circulation, this box-model permits the description of the spring phytoplankton bloom in the whole Channel. Spring western thermal stratification has not been taken into account; consequently, the earliest phytoplanktonic development is observed in the eastern Channel, followed by the western, deeper part. This model also shows the influence of nutrient supply from the rivers on the Channel ecosystem, and particularly the influence of the river Seine on the chlorophyll concentrations along the eastern French coast. Comparison of calculated data with measurements shows a fairly good agreement in the eastern Channel but discrepancies are encountered for the western part....

Marine cytophaga-like bacteria (CLB) isolated from diseased reared sea bass (Dicentrarchus labrax L.) from French mediterranean coast
Provedor de dados: 5
Autores: Pepin, Jean-francois; Emery, Eric.
During spring of 1993, an epizootic outbreak occurred in a sea bass farm, located on the French Mediterranean coast. The cumulative mortality reached 25%. First examination of cutaneous lesions revealed filamentous bundles of flexuous bacteria which exhibited gliding motility. Bacterial growth was obtained only from skin lesions. The biochemical characteristics of isolates are described. Pathogenicity tests of representative slrains were carried out. Until fuller data is available, the pathogen here reported was provisionally identified as a Cytophaga·like bacterium (CLB).

Micronecton et macroplancton en Mer Ligue (Méditerranée) : migrations nycthémérales et distributions verticales
Provedor de dados: 5
Autores: Sardou, J; Andersen, V.
Vertical distributions and diel migration of some species of micronekton and macroplankton are given in the 0-965 m water column on a fixed station in the Ligurian Sea (Northwestern Mediterranean Sea). The hauls performed with a multiple opening/closing net system permit detailed description of the vertical distributions of eighteen species: five euphausiids, one mysid, one decapod, three fishes, three siphonophores, one hydromedusa, one pyrosomid and three pteropods. Only the euphausiid Stylocheiron longicorne and the fishes Cyclothone braueri and C. pygmaea show no migratory behavior. The other species perform migrations of more or less large amplitude: 155 m as a mean for the mysid Eucopia unguiculata until 630 m for the decapod Gennadas elegans. All...

La qualité des eaux dans l'Estuaire de la Gironde. 1- Traitement des données. 2 - Synthèse
Provedor de dados: 5
Autores: Maurice, Laurence.
The main problem of the Girond estuary is a pollution by the cadmium. During this last ten years, the good quality of the water is proved by the analysis of the main physico - chemical and biochemical parameters and bacteria. But since 1989, straight to the Blayais power station, the BOD5 varied between 2 and 3,5 mg.l-1 and a diminution of the dissolved oxygen has been observed; it's probably caused by the accumulation of biodegradable organic matter in the maximum turbidity zone during years characterized by low river flows. For average river flow, urban discharges takes part for 20 % in total fluxes of BD05; in 1991, this part attempts 35 %. During the last 7 years, the pluriannual evolution of the nitrate concentrations measured in the Garonne river...

A phytosociological method for interpreting plankton data
Provedor de dados: 5
Autores: Fromentin, Jean-marc; Ibanez, F.; Legendre, P.
Multivariate techniques allow data sets to be summarised, but are not deslgned to causally model ecological phenomena. The ambiguity of the interpretation results from the ambiguity of the scaling space. The phytosociological method proposed by Grandjouan (1982; These d'etat, Universite Louis Pasteur, Strasbourg) is a general interpretive framework allowing separate consideration of 3 distinct reference spaces. a geographical space to visualise the spatio-temporal distribution of the descriptors, an ecological space showing the effects of the environmental variables on the biological descriptors, and a bio-ethological space showing the statistically meaningful species cornmunities. It is thus possible to define the position of each biological category and...

Autores: Weikert, H; Koppelmann, R.
Full-depth profiles of zooplankton numerical abundance and major taxa composition are presented with special attention to the dominant copepod fauna, for directly comparable data sets from sites to a depth of 4 300 m in the Levantine and Red Seas, which are also compared with the deep mid-latitude NE Atlantic. Copepods showed highest proportions of calanoids, cyclopoids sensu lato and harpacticoids in the 333 mum net subsurface samples from the Atlantic. Among the calanoids as the predominant group, there was a distinctly disproportionate, extended and depth-related sequence of zonal dominance by one single species of a family each at mesopelagic and bathypelagic depths in the Levantine Sea and the Red Sea. The mass occurrence of dormant Eucalanus monachus...

Distribution and origin of dissolved aluminum in the english-channel
Provedor de dados: 5
Autores: Chou, L; Wollast, R.
The distribution of dissolved Al in the Channel along the English coast shows the existence of a strong gradient of this element extending over a distance of several hundred nautical miles. These profiles suggest that wind-driven export from the North Sea to the Channel is seasonally important. These findings confirm the predictions of the recent circulation models of Salomon and Breton (1991). A gross mass balance of dissolved Al in the Channel indicates that the input of the river Seine is insignificant and that the contribution of other minor fresh water sources cannot account for the observed values. The input of dissolved Al from the North Sea seems thus to be the most likely largest source of this element in the Channel. This could also be the case...

L'outil est élaboré par étapes successives qui voient la mise en jeu de nouveaux processus et l'introduction de nouvelles variables (Bacher, 1989 ; Raillard, 1991). La forte variabilité spatio-temporelle des matériaux dissous et particulaire de la baie a focalisé l'attention sur les processus hydrodynamiques. Les modèle de couplage des processus physiques et biologiques développés jusqu'à présent ont privilégié la représentation des phénomènes biologiques en moyennant dans le temps et l'espace les phénomènes physiques.

Autores: Laane, Rwpm; Groeneveld, G; Devries, A; Vanbennekom, J; Sydow, S.
Recent measurements (1986-1988) of the distribution of the concentration of different nutrients (nitrogen, phosphorus and silicate) in the Dover Strait have been used, combined with older results, to calculate the total flux (dissolved and particulate) of nutrients into the North Sea. Special efforts are made to take into account in the fluxes the tidal, geographical and temporal variations in the concentrations of the different nutrients. No vertical gradients in the concentration of the different nutrients were found. Increased nutrient concentration was found in the coastal zones of England and France, compared to the Atlantic water in the central part of the Dover Strait The variation within a single year and between different years in the data...

Le cheptel d'huîtres creuses, Crassostrea gigas, du Bassin de Marennes-Oléron a subi ces dernières années des morta lités (mai 88, mai 91, été 1992 et hiver 92-93). Les examens histopathologiques pratiqués durant celles-ci n'ont pas permis de déceler d'agents pathogènes. Les causes avaient été attribuées essentiellement, pour les premiers cas, à un manque de nourriture corrélé avec des conditions de sécheresse (donc un manque d'apport d'eau douce pour le bassin) et à des surcharges trop importantes des biomasses de fiItreurs, huîtres y compris. L'explication du dernier cas de mortalité survenue au cours de l'hiver serait d'un autre ordre: l'abaissement brutal des salinités, notamment dans les claires où étaient épurées soit des huîtres natives fragilisées,...

Defining the chemical character of aerosols from the atmosphere of the mediterranean-sea and surrounding regions
Provedor de dados: 5
Autores: Chester, R; Nimmo, M; Alarcon, M; Saydam, C; Murphy, Kjt; Sanders, Gs; Corcoran, P.
Atmospherically-transported trace metals can play an important role in biogeochemical cycles in the Mediterranean Sea. However, although the magnitude of trace metal air to sea fluxes is initially dependent on the metal concentrations in the air, it is the ''chemical character'' of the aerosol which constrains the fate of the metals in sea water; for example, the solubility of trace metals is considerably greater from anthropogenic than from crustal components. To a first approximation the chemical composition of the Mediterranean particulate aerosol is controlled by the extent to which an anthropogenic-rich ''background'' material, having a mainly European origin, is perturbed by mixing with crustal components having a desert origin. These perturbations...

Le comportement alimentaire de la dorade (Sparus aurata), différent de celui du bar (Dicentrarchu labrax), nécessite une étude des méthodes de nourrissage, préalablement à la mise au point de l'élevage de cette espèce en marais maritimes. Nous avons testé trois systèmes d'alimentation (manuelle, automatique et à la demande) pour lesquels nous avons suivi l'influence sur les performances de l'élevage. Les résultats de cette étude montrent l'avantage de l'alimentation à la demande, sous réserve d'une programmation du fonctionnement des distributeurs pour éviter les éventuelles pertes d'aliments nocturnes. Malgré cela, la distribution manuelle reste une technique performante, même si elle entraîne un sous-nourrissage des animaux. Quel que soit le système...

A realizable force feedback-feedforward control loop for a piston wave absorber
Provedor de dados: 5
Autores: Maisondieu, Christophe; Clément, Alain.
We consider the problem of the absorption of 2D water waves by the horizontal motions of a vertical plane in response to the hydrodynamical force it experiences. The solution of this problem is straightforward in the frequency domain. Unfortunately, the transposition of the frequency domain solution to the time domain by inverse Fourier transforming leads to a non-causal impulse response function. Thus it cannot be used just as it is, neither as a control loop for physical absorbing devices nor as a non radiating boundary condition (NRBC) in numerical modeling. In this paper, we propose a method to derive causal approximations of this ideal controller. Two time-domain absorbing relations are proposed, differing in whether or not one knows a dominant...

Autores: Prou, Jean; Dardignac, Marie-jose.
Since 1979, the IFREMER Laboratory follows mussel recruitement in the Pertuis Breton. Gametogenesis generally begins in September or October and ends in Décember. Spawning may begin in Februrary and continues up ta the end of April, but it usually occurs in the second fortnigh of March. The most important settlement generaly runs after the middle of May up to the middle of June. Duririg the study period, four years are noticeable by lack of settlement : 1982, 1989, 1990 and 1991. This failure thraughout these three last years resulted in a breakdown of the cultivated biomass. The present paper outlines a preliminary analysis on the influence of temperature and sunshine.

Acoustic detection of the spatial and temporal distribution of fish shoals in the Bay of Biscay
Provedor de dados: 5
Autores: Scalabrin, Carla; Masse, Jacques.
Echo sounder data were used to investigate the spatio-temporal variability of shoal behaviour in the Bay of Biscay. Data collected from annual surveys were processed using MOVIES-B software in order to mcasure this variability. The software was designed to measure morphological, energetic and space-time distribution descriptors from the acoustic signal received from fish shoals. Two surveys, DAAG 90 and DAAG 91, provided the appropriate characteristics for such an analysis. The survey's objective was to obtain relative abundance indices for the anchovy (Engraulis encrasicolus) biomass in the Bay of Biscay. The surveys were carried out in the same area (southern Bay of Biscay), at the same period (April) within one year interval (1990 and 1991), using the...

Precision of acoustic fish abundance estimates: separating the number of schools from the biomass in the schools
Provedor de dados: 5
Autores: Marchal, Emile; Petitgas, Pierre.
The gulf of Cariaco, Venezuela, is a rather isolated piece of coastal ocean where spatio-temporal variability has been measured. In 1986, three repeated surveys have been carried out in this gulf. The important differences in biomass estimates are attributed to sampling error only. The biological nature of this variability is studied. It is due to a high concentration of the biomass in a few schools and correlatively to the hit or the miss of these large schools, during the sampling. Structural information for predicting them is sought. Also, the number of schools per elementary sampling distance unit (ESDU) and the biomass in each school were measured by echointegration. It is found that there is no clear relation between these two variables. Thus their...

On the variability of yellow substance in the skagerrak and the kattegat
Provedor de dados: 5
Autores: Karabashev, Gs; Khanaev, Sa; Kuleshov, Af.
The variability of ''yellow substance'' in waters of the Skagerrak and the Kattegat was studied during the international Skagex programme in 1990 and 1991. Data on attenuation of light and fluorescence of dissolved organic matter (DOM) in sea water were collected with a spectral transmissiometer and a submersible fluorometer within a depth range of 0-250 m at several stations. More than fifty-fold variations of fluorescence intensity over space and time were due to the combined action of different sources of DOM in the straits. The surface maximum of fluorescing DOM, related to river outflow, was spreading from Oslo fjord to the central Skagerrak in late spring. This maximum may be ecologically important because it diminishes shortwave PAR. In the autumn...

Nonsteady state diffusion and advection model of transient concentration-depth profiles from the barbados accretionary complex
Provedor de dados: 5
Autores: Blanc, G; Doussan, C; Thomas, C; Boulegue, J.
We present a non-steady-state diffusion and advection model that describes the distribution of methane, manganese and silica concentrations versus depth at sites 671, 676, and 672 of ODP Leg 110 through an oceanic sedimentary pile undergoing horizontal shortening by means of thrust-faults and folds. The model suggests that the distribution of these chemical components above and below fluid flow conduits is controlled by molecular diffusion. Upward fluid advection from the pathways to the surrounding sediments appears to be without significance for this environment (about 1.10(-11) m.s-1, i.e. almost-equal-to 0.3 mm.yr-1). Estimates of the time necessary to produce the diffusion profiles indicate that average ages of the chemical anomalies increase from...

Bilan des connaissances relatives à la faune et à la flore, aux paysages, à l'occupation du sol - Inventaires des contraintes d'environnement - Biologie de l'estuaire de la Gironde - Synthèse des prospective

Autores: ,.
Sur les quelques 150 publications recensées sur la biologie de l'estuaire, seulement 18 ont été publiées avant 1975. Or c'est à partir de 1975 que le CNEXO et EDF ont commencé à promouvoir et soutenir les études d'écologie en Gironde dans la perspective de la construction de la centrale du Blayais. Ceci montre le désintérêt de la communauté scientifique pour l'écologie estuarienne dans les années 60-70 alors que l'écologie terrestre et limnique était en plein essor.

Pisciculture marine et environnement en France: specificite par rapport a l'eau douce
Provedor de dados: 5
Autores: Kempf, Marc; Merceron, Michel; Dosdat, Antoine.
French marine fish farming deals with several species: sea bass, sea bream, turbot, trout and salmon. In 1992, 20 M fingerlings and 2600 t of fish were produced, for a turnover of 165 MFF: This very technical activity is developing, but still fragile and risky. Environment protection regulation applied to marine fish farming directly inspires from that in force in fresh water, which comes from the industry: i.e. the so-called "classified installation" regulation, concerning activities likely to produce polluting effluents. It does not really adapt to diluted effluents, like fish growing ones, and still less to marine farming; this is true for parameters like biological oxygen demand (BOD) and chemical oxygen demand (COB) and, to a lesser extent, for...

Le cycle biologique du priucipal 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 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 précédent.  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 notamment de ses...

Autores: Littaye-mariette, Anne; Mazurie, Joseph.
Since 1989, an homogeneous Crassostrea gigas oyster stock has been distributed once a year on several rearing sites in Brittany (3 populations per site). The main quantitative and qualitative growth descriptors, which reflect water quality effects during the monitoring period, are estimated at the end of each year. The 1989-1992 analysis prompted us to describe various growth responses correlated to biotops: oyster production in open areas influenced by oceanic waters was fairly constant in quality, including size and Polydora sp. infestation. In contrast, oysters in estuarine areas, partly affected by eutrophication (e.g., Aber Benoît, Pen Bé), or with a low carrying capacity, were characterized by weight and Polydora sp. infestation heterogeneity. These...

Data collected during two embarked observers campains in 1992 and 1993 and the results of a sighting survey in 1993 give an estimation of the population size of common and striped dolphins (61 888 and 73 843) and mean values of ratio fishing of mortality (0.7 and 1.6%). A model was built in order to simulate the effect of the 5% upper limits of fishing mortality (1.5 and 3%). These values would leed to an annual rate of decrease of -1 %. It is unlikely that such values would jeopardize the survival and the presence of these species. Total incidental catches represent 15% of these total catch; albacore tuna...

Autores: Latrouite, Daniel; Noel, Philippe.
Few observations have been reported on the reproductive cycle and size at maturity of female edible crab in the Channel. This could be linked to non catchability of berried females. During the present study carried over three different years, females were taken from commercial catches prior to the spawning period and placed in tanks in the laboratory. The various criteria used to establish the mean size at first maturity are discussed and the relation between size and functional maturity is described. The smallest berried females are at a carapace length of 76mm, and maximum values are reached at about 105mm. The mean value is between 85 and 90mm carapace length. The duration of the spawning period was the same in each years, extending from mid-November to...

Evolution of oyster aquaculture : problems and perspectives
Provedor de dados: 5
Autores: Heral, Maurice.
The total marine molluscs produced by aquaculture had increased from 1984 to 1990 by 1 000 000 tons going from 1 993 985 tons to 2 964 688 tons. The oyster production remained constant with 870 000 tons. Crassostrea gigas, the Japanese oyster, represented more than 80 % of the oyster production but high mortalities appeared in different countries connected to end of winter and summer mortalities and development of new diseases. The cultivation of Crassostrea virginica, the American oyster, was limited (80 000 tons) by the spreading of two diseases (MSX and dermo) destruction of habitat and over-exploitation. Production of the fiat oyster Ostrea eduIis was still very limited by the presence of the Bonamia diseases in a11 the countries except on...

During the Kanaut cruise of the submersible Nautile and its mothership Le-Nadir (15 November-16 December 1992), one dive was devoted to the detailed study of a specific area of the neovolcanic ridge of the MAR around 29-degrees-06'N and 43-degrees-11'W. This study emphasizes the importance of the juxtaposition and the stacking of hundreds of small volcanoes in the construction of a neovolcanic ridge and confirms the general observation made from multibeam and side-scan sonar data. The very large magnetic anomaly associated with these massifs favours an extreme freshness.

Have the recent hydrological changes in the northern gulf of guinea induced the sardinella-aurita outburst
Provedor de dados: 5
Autores: Binet, D; Servain, J.
Sea surface temperature along the northern coast of the Gulf of Guinea drops abruptly twice a year, with a moderate decrease in boreal winter and a greater one in summer. Several mechanisms have been proposed to explain these coolings: Ekman upwelling due to local wind, remote wind forcing in the western Atlantic, geostrophic adjustment to the Guinea current variations or eddies created by headlands in the current. The resulting seasonally-induced plankton production has led to the development of pelagic fisheries, with dramatic increases in Sardinella aurita catches in Cote d'Ivoire and Ghana during the last decade and new spatial and seasonal distributions. A study to account for these changes was undertaken on the basis of wind and temperature data...

The artisanal fisheries industry has experienced a major development over the 80's: technology has improved and ship building costs have increased. The firms' economic behaviour and financial performances have shown that the marginal profitability of capital is lower for large units than for small units, the latter being used by coastal fisheries. Overall, conclusions on the financial situation of the industry must be qualified. Public intervention has materialized through (1) an increasing amount of state aids supporting modernization investment (Brittany being the most supported region), (2) more political and financial involvement of regions as a result of more administrative and decision making responsibilities being devolved to them, (3) the...

Des piscicultures marines se sont développées sur le littoral Manche Atlantique qui offre de nombreux sites abrités et faciles d'accès. Ces élevages piscicoles, le plus souvent situés à proximité de zones de tradition conchylicole, sont sources de rejets de substances organiques (aliments non consommés, fêces), minérales (produits azotés) et zoosanitaires (médicaments) (Gowen et Bradbury, 1987). Ce n'est que depuis environ cinq ans que des équipes de recherche, pour la plupart scandinaves, se sont plus particulièrement intéressées aux substances chimiques, notamment aux antibiotiques, rejetées dans le milieu des piscicultures marines en cage (Samuelsen, 1989 ; Bjorklund et al., 1990 ; Lunestad et Goksoyr, 1990 ; Bjorklund et al., 1991).

The use of mineral magnetic measurements to study the transport and sedimentation of particles in the Gulf of Lions (NW mediterranean)
Provedor de dados: 5
Autores: Scoullos, Mj; Zeri, C.
Mineral magnetic and chemical studies indicate the impact and great importance of atmospheric versus riverine input of particles in the sediments of the Gulf of Lions and provide some strong indications about the presence of anthropogenic particles in offshore deep sediments of this region. The data indicate that Saharan dust and anthropogenic particles coexist at several depth intervals in the sediment, supporting the hypothesis that Saharan dust episodes could play an important role in facilitating deposition and coprecipitation of anthropogenic particles from the atmosphere and the water column.

Growth rates and RNA/DNA ratios were significantly affected by the nature of the detritus offered. However, there was no significant (n = 65, r = 0,07) correlation between growth rates and RNA/DNA ratios. These results show that there were significant qualitative differences in the tested detritus. They suggest that the...

L'absorption Dynamique des Ondes de Gravité en Régime Instationnaire
Provedor de dados: 5
Autores: Maisondieu, Christophe.
This study deals with the dynamic absorption of water waves. We focus here our attention on the case of a simple devce, a 2D piston, in order to exploit the well-known expressions of the potential as far as possible in the design of new absorption laws. We consider a semi-infinite two dimensional wave tank closed by a mobile vertical plane. An unsteady wave train generated at infinity impiges on this plate. The problem of the dynamic absorption consists in finding, in real time, the velocity to be given to the plate so that the radiated and the reflected wave trains should cancel each other. We propose here to derive this velocity from the forces measured on the plate. We first derive a frequency dependant transfer function between the optimal velocity of...

Autores: Soletchnik, Patrick; Heral, Maurice; Razet, Daniel; Bougrier, Serge; Geairon, Philippe.
Ecophysiological study was conducted on the japanese oyster (Crassostrea gigas) reared in Marennes-Oléron bay (France), during May 1992. Most of the somatic growth of the oyster occured during that month. The measurements were achieved from a removable laboratory stated in Le Chapus for 3 days at different tide level (coefficient of 49, 57, and 88). The food conditions were monitored through a computer with a continuous record of the turbidity during aIl the tidal cycle.  In spite of an important variation between the food conditions in mean seston load, from 13,5 to 54,6 mg/!, the available organic matter ranged from 3 to 4,9 mg/l. The rate of organic matter in the water ranged 22 % to 9 %. The organic selection efficiency was significantly higher for the...

Evaluation de la qualité sanitaire des gisements de moules non-emergents de l'estuaire de la Loire Octobre-Novembre 1992
Provedor de dados: 5
Autores: Allenou, Jean-pierre; Dumont, Francoise; Menanteau, Chantal.
Les gisements de moules non-émergents de l'estuaire de la Loire sont régulièrement exploités avec une production annuelle pouvant atteindre mille tonnes. Le caractère insalubre des gisements nécessite un traitement des moules avant la commercialisation, reparcage ou purification en bassin. Une bonne connaissance de la qualité initiale des produis permet d'optimiser le traitement. Cette étude, effectuée durant la campagne de pêche, a pour objectif l'estimation du niveau de salubrité des gisements. Elle a reposé sur la recherche des germes témoins de la contamination fécale, les coliformes fécaux. La contamination chimique a été discutée à partir des résultats obtenus dans le cadre du RNO sur les gisements de moules découvrants de l'estuaire.

L'aquaculture francaise en bref
Provedor de dados: 5
Autores: Dosdat, Antoine; Kempf, Marc; Merceron, Michel; Paquotte, Philippe.
Aquaculture in France is characterised by great species diversity. Furthermore, traditional activities (farming of marine shellfish and freshwater fish) coexist with still-developing recent ones (marine fish farming, new pratices in shellfish rearing, etc.). Traditional cultures are the main contributors to the tonnage produced and employment generated. Another noticeable point is the importance of the western part of the country, which carries the main part of the production (&gt; 80 %): the Channel Atlantic coast for shellfish, and nearby rivers for freshwater salmonid farming. On the Mediterranean coast, marine fish farming of bass and bream, as well as shellfish production by new methods (mussels on longlines in open waters), are developing. Important...

Spatial and temporal scales in altimetric variability in the brazil-malvinas current confluence region - dominance of the semiannual period and large spatial scales
Provedor de dados: 5
Autores: Provost, Claire; Le Traon, Pierre-yves.
Two years of Geosat data are used to investigate the space and time scales of the mesoscale variability in the Brazil-Malvinas Current confluence region. The mesoscale activity is highly inhomogeneous and anisotropic. The inhomogeneity is characterized by low values of sea level variability in the Malvinas Current (less than 8 cm, i.e., eddy kinetic energy less than 150 cm2 s-2), intermediate values in the Brazil Current (typically 16 cm/800 cm2 s-2) and high values in the Brazil-Malvinas frontal region (30 cm/1700 cm2 s-2). The anisotropy is marked with meridional variances of velocity that are typically three times larger than zonal ones in the region of maximum variability. Mesoscale variations are dominated by relatively large spatial scales and...

Autores: Delpech, Jean-paul.
Longtemps, le port de Boulogne/Mer a, sans concurrence, été le premier port de pêche fraîche de France. Se disputant cette primauté avec Lorient depuis les années 80, il a repris cette place au début des années 90 et ne l'a plus quitté depuis. L'Office des pêches puis l'ISTPM et maintenant l'IFREMER y ont donc logiquement maintenu un laboratoire de recherches halieutiques depuis 1883.

Risques en aquaculture et implications pour un système d'assurance : éléments de réflexion
Provedor de dados: 5
Autores: Antona, Martine; Paquotte, Philippe.
Les expériences en matière d"assurance des entreprises de cultures marines se sont développées dans la décennie 70. Elles se sont caractérisées par une couverture très large du risque avec des taux de prime importants qui ont restreint le champs des assurés et par  une couverture géographique très faible. Dans la pratique, seuls les ostréiculteurs de Bretagne Nord ont été assurés. L"arrêt brutal de ces expériences à la fin des années 70 est dû au retrait des assureurs après I"épizootie de l'huître plate. La mise en place de systèmes d"assurance en aquaculture nouvelle à la fin des années 80 et leur réexamen actuel pour la conchyliculture ont été favorisés par plusieurs facteurs : - le développement des productions aquacoles sur incitation publique, - la...

Hydrological regime and water volume transport in the faeroe-shetland channel in summer of 1988 and 1989
Provedor de dados: 5
Autores: Schlichtholz, P; Jankowski, A.
This paper deals with the hydrological regime and the water volume transport in the Faeroe-Shetland Channel in early summer of 1988 and 1989. The oceanographic conditions in the channel and in its vicinity are reviewed briefly. Then, some thermohaline and dynamical analyses are presented. The results are based on the vertical CTD soundings carried out during the cruises of R/V Oceania in the region of the channel in July 1988 and in July 1989. The upper part of the water column in the channel, down to the bottom of the main pycnocline, was warmer and more saline in 1988. However, the net transport of warm waters with theta greater-than-or-equal-to 3-degrees-C was oriented to the north, and was rather larger in 1989 (1.8 +/- 2.0 Sv) than in 1988 (1.0 +/-...

Autores: Duclerc, Jean; Bertrand, Jacques.
The laying out of an offshore site in the gulf of Lion has been realized by immersion of concrete structures in 1985. Two complementary studies have been conducted in order to estimate the impact of such artificiel reef. Gillnet fishery surveys have been done in the vicinity of the structures and also on a control site. Moreover the local profcssional fishery has been investigated for two periods of 16 months, one berore and one arter the reef immersion. The results of the gillnet surveys have already been submitted to publication and the present study displays the investigations concerning the local fishery. It has been shown by the gillnet fishing surveys that the artificial reef led in their very close vicinity to variations in marine species...

A 20 g clam total weight was reached in 19 months at a 300.m-2 density using a mixture of sea water and Skeletonema costatum algae. Currently, initiating an intensive ongrowing clam business is not economically viable since the marketable value is at a record low of 30FF.kg-l . Phytoplankton production and sea water pumping cost effectiveness should be improved. However, a company's activities may be diversified using intensive clam rearing techniques but without labor staff increase.

The determination of polycyclic aromatic hydrocarbons in seawater from the Fluxmanche transect (Dover Strait)
Provedor de dados: 5
Autores: Law, Rj; Whinnett, Ja.
Concentrations of a range of polycyclic aromatic hydrocarbons (PAH) were determined by means of coupled gas chromatography-mass spectrometry (GCMS). Water samples were collected, using a contamination-free sampling device, at two depths (Im subsurface and 3 m above the seabed) at each of the six stations established in the Dover Strait. The stations were occupied during June and October 1990, and July 1991. Concentrations of PAH were often close to or below the limits of detection for samples of 10.8 1 volume, although a number of samples exhibited high concentrations (of naphthalenes in particular) which were apparently derived from shipping inputs in the Dover Strait. Future work will require the development of methods with lower limits of detection, and...

Hydrothermal methane venting between 12°N and 26°N along the Mid-Atlantic Ridge
Provedor de dados: 5
Autores: Charlou, Jean-luc; Donval, Jean-pierre.
Hydrographic surveys along the Mid-Atlantic Ridge (MAR) between 12°N and 26°N, carried out from 1984 to 1990, show a variable pattern of CH4-rich water column plumes. The vertical distribution of CH4 at stations located every 20–40 km is presented along this 1200-km-long section of the MAR. CH4 venting is clearly demonstrated. CH4-enriched fluids rise from vents as plumes; spreading is confined to the axial valley due to the topography of the MAR. CH4 contents from 45 nmol to 675 nmol/kg are measured in the buoyant plumes above the two active hydrothermal sites (MARK 23°N; TAG 26°N) known at present, whereas CH4 anomalies up to 3.6 nmol/kg are typically observed in plumes emitted either on the inner floor, on the walls, and/or at the top of the rift...

The Flow of Antarctic Bottom Water into the Brazil Basin
Provedor de dados: 5
Autores: Speer, Kevin G; Zenk, Walter.
The total transport of Antarctic Bottom Water across the Rio Grande Rise, including the western boundary, the Vema Channel, and the Hunter Channel is estimated from hydrographic measurements across these pathways. The contribution of the Vema Channel is greatest at 3.9 X 10(6) m(3) s(-1), which is very close to earlier estimates. The western boundary current contribution is 2.0 X 10(6) m(3) s(-1) and that of the Hunter Channel 0.7 X 10(6) m(3) s(-1). The lower values outside the Vema Channel are offset by the important source of mass they form to the lower density classes of bottom water. About 40% of the now is concentrated in the highest density class representing the source of Weddell Sea Deep Water to the Brazil Basin. The flow structure is...

Impact de la variabilité du recrutement sur le stock d'oursins commercialisables de l'archipel de Glénan (Sud-Bretagne)
Provedor de dados: 5
Autores: Guillou, M; Michel, C.
In Brittany, the edible sea-urchin Sphaerechinus granularis (Lamarck) is at the northern limit of its range. Small-scale exploitation of this species occurs in the Glenan islands, in the bay of Concarneau (Finistere, France). Three extensive diving surveys undertaken in 1990, 1991 and 1992 show a significant variation of the stock which was estimated at between 700 and 1400 tonnes during this study. The constant level of the annual sea-urchin harvest suggests that these fluctuations may be attributed to variation in recruitment. This can be considered as non-existent in 1989 and 1992, substantial in 1990 and moderate in 1991. The causes of this variability are complex. It is certainly directly related to the phenology of the reproductive cycle (recruitment...

Autores: Paquotte, Philippe; Fleury, Pierre-gildas.
The development of king scallop (Pecten maximus) culture in France has been subsidised by the State and the Brittany Region for the past 10 years. Technical progress has been made and the public authorities now wish to know if this activity is economically feasible. While continuing research to improve the performance of this type of shellfish culture (culture techniques and physiology), Ifremer (public institute for oceanological research) also undertook an economic assessment on costs, marketability and legal and social limitations. The study of the costs of production presented here was carried out by analysing a pilot farm. This approach helped detail the financial needs and the degree of profitability of scallop farming.

MOVIES-B: an acoustic detection description software. Application to shoal species' classification
Provedor de dados: 5
Autores: Weill, Alain; Scalabrin, Carla; Diner, Noel.
Software, MOVIES-B, developed by IFREMER (Institut français de recherche pour l'exploitation de la mer), enables the recognition of echogram features as acoustic detection structures according to spatial-energetic contiguity criteria. These structures (shoals, plankton layers) are described by energetic, morphological, spatial and temporal descriptors. Specifying acoustic detections as individual shoals will allow shoal by shoal echo-integration and may lead to better biomass estimation and shoal species description. The conceptual and operational framework of MOVIES-B is presented in the first part of this paper. The second part presents preliminary work performed in order to assess the feasibility of classification and possible species identification of...

Le bassin de la Charente avec ses quelques 10 000 km2 et 600 000 habitants est l'objet d'importants prélèvements d'eau.  En effet, outre les besoins propres aux activités industrielles et agricoles et à la population, le fleuve doit assurer l'approvisionnement en eau de la zone littorale qui constitue à la fois un important centre touristique et conchylicole.  Aussi, la résorption des sources de pollution est une action prioritaire.  Une démarche engagée en 1978 sur le bassin charentais et actuellement poursuivie, consiste à définir des objectifs de qualité des eaux superficielles.

Questions sur la dynamique de l'exploitation halieutique

Whether what is at stake is land-use management and stabilising the economy of the shoreline areas for a good number of developed countries or involvement in food self-sufficiency, contributing to the balance of payments and stabilising employment for developing countries, in every instance, the economic and/or political importance of fisheries management as a business sector is far from being marginal in most of the countries concerned. Thus, from the moment the question of the inexhaustibility of the resources was posed, the desire to manage them manifested itself by the emergence of social demand, peculiarly at around the same time as research, due to the involvement of the researchers in the decision-making bodies of land-use and business management...

Water-level variations in the sea of marmara
Provedor de dados: 5
Autores: Yuce, Hy.
Characteristics of water level variations in the Sea of Marmara have been investigated. Long-period oscillations of non-tidal origin have been identified in the analysis. These oscillations are due to regular fluctuations of water level throughout the year caused by meteorological and oceanographic influences. Greater fluctuations are produced by local winds, river runoff and inflow from the Black Sea. These fluctuations increase rapidly in spring and early August, the latter due to Black Sea fresh water inflow. The data show the presence of small amplitude diurnal tidal variations. Far from the entrances to the straits, the Sea of Marmara is not affected by short period tidal oscillations of the neighbouring seas.The harmonic tidal constituents indicate...

Distribution of zooplankton populations in marennes-oleron bay (france), structure and grazing impact of copepod communities
Provedor de dados: 5
Autores: Sautour, B; Castel, Jerome.
Zooplankton distribution in Marennes-Oleron Bay (France) varies during the year and is essentially determined by seasonal rhythms. The whole set of zooplanktonic taxa can be divided into three groups: the first bearing oceanic affinities; the second with estuarine tendencies; and the third more intermediate. Important water flows inhibit the establishment in a specific zone of an autochthonous community (this community is reduced to such species as Acartia discaudata, Acartia grani and Euterpina acutifrons). Zooplanktonic populations reach their maximum abundances at the end of spring and during summer, particularly during spring tide in the inner neritic zone. The estimation of die grazing pressure of copepods (which are the dominant taxa) is variable...

Aspartate transcarbamylase du mesozooplancton et prerecrutement de la sole: les conditions d’une approche systémique en Manche
Provedor de dados: 5
Autores: Bergeron, Jean-pierre.
In temperate neritic areas, meteorological conditions prevailing during winter and the following spring play a major role on the main features of the spring development pattern of pelagic ecosystems. Interannual fluctuations of this environment lead to qualitative and quantitative variations of secondary production which may strongly influence processes regulating the recruitment of many species. A method for assessing pelagic secondary production is based on measurement of the activity of an enzyme, aspartate transcarbamylase, and has been carried out during spring periods for six years in succession, in the southwestern part of the English Channel. These works have permitted the establishment of a close correlation between the quantitative variations of...

An overview of the history, knowledge, recent and future research trends in Mediterranean fisheries
Provedor de dados: 5
Autores: Farrugio, Henri; Oliver, Pere; Biagi, Franco.
The Mediterranean sea is an area which has a longlived oceanographic tradition. Since the remote antiquity, it has been the object of observations and descriptions in which maritime activities and fishing hold a paramount place, This paper presents a synthetic view on the history of the fisheries research and its evolution in the area. The very rich mediterranean fauna and the highly multispecific nature of the catches certainly favoured the fact that the first works were mainly oriented towards attempts of exhaustive descriptions of the vital cycles and biological parameters of a given species. The passage from marine biology sensu-stricto to fisheries research is relatively recent in the Mediterranean, the first attempts to apply some mathematical...

Evaluation quantitative de la crépidule ( Crepidula Fornicata) en Baie de Cancale
Provedor de dados: 5
Autores: Blanchard, Michel; Youenou, Gilles.
La prolifération de la crépidule (Crepidula fornicata), sur le littoral français, est actuellement importante. Ce mésogastéropode, s'il est présent sur une grande surface du plateau côtier, se développe particulièrement dans les secteurs abrités, tels que les estuaires et les baies. Dans les secteurs abrités, cette espèce est depuis quelques années, une gêne sérieuse pour la pratique de la pêche par dragage ou par chalutage, mais également pour la conchyliculture, puisqu'elle occupe de plus en plus largement les secteurs concédés, à tel point que les quantités de crépidules pêchées sont supérieures à celles des espèces commerciales. La crépidule est donc un compétiteur spatial des espèces benthiques littorales. C'est aussi un compétiteur trophique,...

Relationship between larval type and geographic range in marine species - complementary observations on gastropods
Provedor de dados: 5
Autores: Bhaud, Mr.
From a faunal list of 216 of the most common species of prosobranch gastropods at Beaufort, North Carolina, a group of 87 species was selected on the basis of known life cycles and geographic distributions. The larval types were categorized as teleplanic, actaeplanic, or nonplanktonic. The presence of these species in eight approximately equivalent latitudinal zones along the western shore of the Atlantic Ocean was then recorded (Scheltema, 1989). This list has been used, in the present paper, in three different ways: to identify homogeneity or heterogeneity of spatial distribution of the three biological groups; to record the presence of species in geographic sectors defined on the basis of average annual sea surface temperature; and to compare, at the...

La prise en compte des contraintes d'environnement dans l'economie des entreprises aquacoles
Provedor de dados: 5
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 part of...

L'étude des processus de changement nous conduit à explorer certains mécanismes dynamiques. Sans entrer dans des querelles d'écoles, on exclura ici l'immobilisme en admettant comme le précise Le Fur que l'équilibre est impossible dans un environnement fluctuant. On suppose donc ici qu'un processus dynamique est un processus de changement.

Effects of twelve pesticides on larvae of oysters (Crassostrea gigas) and on two species of unicellular marine algae (Isochrysis galbana and Chaetoceros calcitrans)
Provedor de dados: 5
Autores: His, Edouard; Seaman, Matthias.
The effects of seven herbicides, four insecticides and one molluscicide were tested at concentrations of up to 10 mg/l on larvae of oysters, Crassostrea gigas (9 days exposure), and on laboratory cultures of the algae Isochrysis galbana and Chaeloceros calcilrans (21 days exposure). Ali of the pesticides tested had significant toxic effects on at least one of the test organisms. The strongest effects were those of lindane and isoproturon on survival and growth of C.gigas larvae, and of isoproturon and carbetamide on growth of Isochrysis and Chaeloceros cultures. The log-probit model for the relationship between dosage and effect, and Haber's rule for the relationship between duration of exposure and effect, hardly ever applied to our data. In sorne cases...

Le milieu marin côtier est constamment soumis à des apports polluants continentaux. Des agents pathogènes, parmi lesquels des virus entériques humains, présents dans ces rejets, contribuent à la contamination microbiologique du littoral. La survie des virus dans l'eau de mer est prolongée grâce à leur association aux matières organiques, aux particules en suspension et aux sédiments qui constituent un véritable réservoir de virus. Les fruits de mer, de par leur activité de nutrition par filtration, se comportent comme de véritables filtres à micro-organismes : en même temps qu'ils absorbent les éléments nécessaires à leur alimentation, ils retiennent et accumulent activement les virus libres ou associés à des supports particulaires.

Chemical, isotopic and enzymatic monitoring of free and enclosed seawater : implications for primary production estimates in incubation bottles
Provedor de dados: 5
Autores: Collos, Yves; Descolas Gros, Chantal; Fontugne, Michel; Mortain-bertrand, A; Chretiennot-dinet, Marie-josèphe; Frikha, Mg.
Enclosing seawater samples in incubation bottles had 3 main effects on the phytoplankton: first, a large (5-fold in 12 h) increase of phytoplankton biomass, due to the release of grazing pressure by herbivores, Second, an increase (2-fold in 6 h) in ribulose biphosphate carboxylase specific activity (per unit chlorophyll a), which could be due to a smaller dependence on regenerated production (less heterotrophy on excreted compounds). This was also supported by a tight relationship between phosphoenol pyruvate carboxykinase activity and dissolved ammonium. Finally, the large changes in the carbon isotopic composition of the incubated particulate matter, which were highly dependent on the dissolved inorganic nitrogen concentration, were due mainly to...

As part of the MAST I-FluxManche initiative, a monthly (September 1990 to November 1991) sampling programme has been carried out in the Dover Strait. Samples were taken (weather permitting) at two depths at each of six standard stations between Folkestone and Cap Gris-Nez. Data from all surveys, in conjunction with estimates of water movement derived from hydrodynamic numerical model, have been used to calculate fluxes of nutrients between the Channel and the North Sea. Results demonstrate that although nutrient concentrations are lower in the central channel-waters than in the coastal zone, the dissolved nutrient flux to the North Sea is mom important for stations of the central part of the Dover Strait as water.

The aim of the 20 Nautile dives of the recent Kanaut cruise was the study of the Kane Fracture Zone from its intersection with the Mid-Atlantic Ridge up to 80 km to the west. The dives have been conducted along four massifs located along the southern wall of the fracture valley. The flanks of the massifs consist of slightly tilted peridotites, gabbros and basalts, which have been exposed along normal and strike-slip major faults. No dike complex similar to that observed along the ZF Vema was observed The observed sections show pervasive cataclastic deformation and greenschist-facies metamorphic overprint.

Videoscopic study of deep-sea hydrothermal vent alvinellid polychaete populations: biomass estimation and behaviour
Provedor de dados: 5
Autores: Chevaldonne, P; Jollivet, Didier.
Biomass is a poorly documented parameter of the hydrothermal ecosystem, partly due to the difficulties in estimating it. Because the hydrothermal alvinellid polychaete worms mostly live in tubes, and on very irregular surfaces difficult to sample, an original biomass estimation method based on video analysis was proposed and tested on populations of the East Pacific Rise at 13-degrees-N. The area covered by the 3 main alvinellid species was accurately estimated from geometrical calculations in oblique-angle conditions, requiring only 3 object measurements on the monitor screen. The total density of alvinellids was estimated on video by modelling the pattern of worm movements in and out of their tubes. The Richards function was found appropriate to model...

Populations of Abra alba (Wood) (Mollusca : Bivalvia) were studied over a fifteen-years period at three sites: the southern part of the North Sea (Gravelines area), the Bay of Seine, and the Bay of Morlaix in the western English Channel. These surveys provide an example of long-term changes in a species considered as ''opportunistic'' and as a ''biological indicator'' of disturbance. A summed cumulated function was used to compare the changes of the Abra alba populations and of mean air temperature in each area. The graph of this function shows the timing and duration of changes. Four or five main periods were identified at each site, with a succession of periods of abundance, stability, and decrease. The abundance periods were separated by ten years in...

Variations in demographic parameters between intertidal populations of Nereis virens and Nephtys caeca were studied. These polychaetes are major component of the Macoma balthica community in the Lower St. Lawrence estuary (Quebec, Canada). We compared spatial distribution between differently oriented shores in a small geographic area. Our results revealed an interpopulation variability that appears to be dependent on hydrodynamical processes, edaphic parameters and biological interactions. In north and northeast oriented flats, the higher densities of young individuals of Nereis virens are found in the higher tidal levels where we observed larval recruitment and the highest organic matter contents. On the other hand, the lower densities of adult worms are...

La conservation des échantillons a souvent constitué un problème tant pour les chimistes que pour les biologistes. Si les chimistes semblent satisfaits de leurs techniques de conservation, les biologistes quant à eux sont indécis du fait que l'action toxique se modifie au cours du temps et selon la technique employée (réfrigération, congélation, lyophilisation, conservation en azote liquide à -196°C). Le présent rapport constitue une étude préliminaire qui, si elle est poursuivie, pourrait permettre de déterminer le mode de conservation le plus approprié pour chaque type d'échantillons.

Generation of a residual current by interaction between the coastal boundary-layer and the ekman layer in a tidal motion
Provedor de dados: 5
Autores: Aelbrecht, D; Dhieres, Gc; Zhang, Xz.
Some experiments have been made with the large rotating tank at the Institut de Mecanique de Grenoble to reproduce a sinusoidal flow along a vertical wall, over a flat bottom, with or without slope, in a homogeneous fluid. The objective of these experiments was to simulate a tidal motion, restricted to its main harmonic component M2, parallel to a vertical coast; and to demonstrate a particular mode of generation of residual circulation near the coast as a result of the interaction between friction, background rotation of the system (Ekman pumping) and oscillatory motion (Stokes effects). Moreover, the stabilizing (or otherwise) effects of the Earth's rotation on this shear flow may modify the rectification process. The configuration is in a good agreement...

Estimation des flux engendrés par l'activité métabolique des mollusque filtreurs intertidaux en baie de Saint-Brieuc
Provedor de dados: 5
Autores: Blanchard, Michel; Gros, Philippe.
Three main intertidal macrofauna communities are identified in Saint-Brieuc Bay: a Macoma balthica community, a Tellina tenuis community; and a third community with Cerastroderma and Tellina tenuis. Physiological parameters such as filtration, respiration and excretion are examined, for the filter-feeding molluscs with the highest biomass (the cockle Cerastoderma edule, the tellinid Tellina tenuis, and the blue mussel Mytilus edulis), either through laboratory experiments, or through previous literature. These results are used together to build up an annual energy budget for the complete soft bottom community, and to observe trophic relations. Results show that the mussel population has a negative influence on the cockle beds that lie just above.

This work is the result of collaboration between the English, French, Channel Isles and Belgian laboratories which are involved in a study of the English Channel. Its subject is the activities of fleets and fleet interactions, and it complements other work on the biogeographical identification of Channel fish and shellfish stocks (published), and on modelling the fleets' interactions as they exploit the resources (in preparation). The concept of a métier is defined as being the use of one fishing gear to catch one or several species targeted during a particular season in a given area. On this basis, 74 métiers were identified during 1989-90. For each métier we give a brief description of the catching gear, the target species and most usual by-catch, the...

On the relationship between scattering layer, thermal structure and tuna abundance in the eastern atlantic equatorial current system
Provedor de dados: 5
Autores: Marchal, E; Gerlotto, F; Stequert, B.
A migrating Sound Scattering Layer (SSL) was observed in the Eastern Atlantic equatorial system during warm and cool seasons. Averaged column scattering strength was nearly the same during daytime at 350-400 m depth and during night-time close to the surface. The depth of the nocturnal SSL was correlated with the depth of the thermocline. In the warm stable season, the maximum column scattering strength was found south of the equator in a dome shaped structure. In the cool season, the maximum was found at the northern convergence where the thermocline was well-marked, whereas upwelled waters were acoustically poor. For the warm season, this pattern is consistent with the distribution of chlorophyll, zooplankton and micronekton. For the cool season, it fits...

Topography and grounding in a simple bottom layer model
Provedor de dados: 5
Autores: Speer, Kevin G; Tziperman, Eli; Feliks, Yizhak.
A reduced-gravity model for a dense bottom layer under a motionless deep layer is used to investigate bottom layer flow with topography. The two competing effects in the model are topography, which introduces a topographic beta effect, and strong layer thickness variation, which allows for the possibility of zero-layer thickness or grounding. The goal is to arrive at a simple, observationally relevant characterization of the model which can help to distinguish different dynamical mechanisms operating in the ocean. Several regimes are identified, including situations for which the layer depth goes to zero with and without topography. Ways of distinguishing observationally between competing effects are suggested. The study is motivated by the observed shift...

La mytiliculture en baie de Vilaine - Aspect socio-économiques. Situation sanitaire des zones d'élevage (Année 1988)
Provedor de dados: 5
Autores: Chauvin, Jacky.
La culture de moules sur bouchots est apparue en baie de Vilaine vers la fin du 19ème siècle. Aujourd'hui la mytiliculture compte 65 entreprises, génère 130 emplois et produit annuellement 2000 à 2600 tonnes de moules. Le site de Vilaine se place au 5ème rang des centres mytilicoles français. L'industrie agro-alimentaire, l'agriculture et l'urbanisation représentent l'essentiel des apports polluants du bassin versant de la Vilaine. Le suivi réalisé en 1988 a permis d'évaluer les niveaux de contamination bactériologique des eaux conchylicores de la baie de Vilaine, en prenant comme intégrateur de cette contamination bactérienne, la moule Mytilus edulis.

Periodic stratification in the rhine ROFI in the north-sea
Provedor de dados: 5
Autores: Simpson, Jh; Bos, Wg; Schirmer, F; Souza, Aj; Rippeth, Tp; Jones, Se; Hydes, D.
The nature of the physical regime in the vicinity of the Rhine ROFI (Region Of Freshwater Influence) has been determined in a series of collaborative observations. Extensive surveys with shipboard CTD/rosette systems have been used to complement time series observations by an array of moorings instrumented with currentmeters, transmissometers and fluorimeters. The observations reveal a highly variable system in which the influence of the freshwater input from the Rhine extends northeastwards from the source and out to 30 km from the coast. The mean flow within this region is generally parallel to the coast (northeastwards) and with surface speeds, determined by the HF radar, of 15-20 cm.s-1. The residual current at sub-tidal frequencies was strongly...

Evaluation of dissolved and particulate arsenic flux in the Dover strait (fluxmanche program)
Provedor de dados: 5
Autores: Michel, Pierre; Averty, Bernard; Noel, Joelle; Sanjuan, Jane.
In order to estimate arsenic flux from the English Channel toward the North Sea, 168 samples were obtained from September 1990 to November 1991 along a transect between Boulogne and Folkestone comprising six stations and two depths. Organic and inorganic arsenic were measured in dissolved phase and total arsenic in suspended particles. The mean concentration of dissolved total arsenic in water was 1.38 +/- 0.12 mug.l-1. The variability of measured concentrations was low, particularly for the four intermediate stations. Results were slightly more sensitive for English (1.38 +/- 0.12 mug.l-1) and French (135 +/- 0.11 mug.l-1) coastal stations due to exchanges with shallower sediments. Dissolved organic arsenic was nearly negligible from December to March...

Feeding behaviour of the mussel, Mytilus edulis : responses to variations in quantity and organic content of the seston
Provedor de dados: 5
Autores: Bayne, Bl; Iglesias, Jip; Hawkins, Ajs; Navarro, E; Heral, Maurice; Deslous Paoli, Jean-marc.
Mussels were fed four concentrations of seston (between 0•99 and 10•3mgtotalseston P), comprising three levels of organic content (71•9, 63•6 and 40•8%), made up from natural silt and two species of cultured phytoplankton. Two of the seston concentrations were below, and two above, the threshold at which pseudofaeces were produced. Measurements of physiological traits (filtration rates, pseudofaeces production, selection efficiency, absorption efficiency, absorption rates and rates of oxygen consumption) were made after 2 days and, for two of the seston concentrations, also after 12 days. When fed at a high concentration of seston of low organic content, the mussels increased their filtration rate, rejected a higher proportion of filtered material as...

Simultaneous deep and intermediate depth convection in the northern levantine sea, winter 1992
Provedor de dados: 5
Autores: Sur, Hi; Ozsoy, E; Unluata, U.
The northern Levantine Sea is the primary source region for the Levantine Intermediate Water (LIW) in the Mediterranean Sea. The Deep Water (DW) of the Eastern Mediterranean mainly originates in the Adriatic basin, but local contributions from the Levantine Sea have also been suspected in the past. Observations in the northern Levantine Sea during March 1992 shed new light on the above processes, showing simultaneous formation of DW in the cyclonic Rhodes Gyre (Rhodes Gyre) area, and of LIW in the adjacent regions. The deep convection region coincides with the permanent dome structure of the Rhodes Gyre, where overturning of the water is generated by cooling during sufficiently severe winters. The LIW is produced in a much larger area of the northern...

Début 1990, l'IFREMER et les Affaires Maritimes sont contactés par un ostréiculteur de l'Aber-Benoit afin d'effectuer le constat de mortalités survenues depuis 1989 sur ses concessions. L'expertise révèle des taux de mortalité allant de 20 à 70% sur les huîtres en élevage, tous âges et toutes techniques confondues (Cl. Le Bec, 1989). Dès cette date, un gradient décroissant de mortalité est noté d'amont en aval et du chenal à la berge. Ces mortalités anormales, par comparaison avec les autres bassins ostréicoles bretons, sont également observées sur les poches expérimentales des stations de l'Aber Benoit du réseau "Huître Creuse Bretagne" (C.

Management practices and sugar end potatoes
Provedor de dados: 18
Autores: Westermann, Dale T.
French fries processed from sugar end potatoes become  undesirably dark on one end while remaining  light on the other (fig. 1). The darkening is usually  caused by a higher concentration of reducing sugars  in the darkened end of the fry strip. Sugar ends are  associated with tubers that are pointed on the stem  end but also occur in ideally shaped tubers.  "Translucent end," "jelly end," and "sugar end"  describe the same physiological tuber problem. Translucent  end tubers with high levels of sugars develop  jelly end rot after progressive tissue breakdown  occurs. The Russet Burbank variety is particularly  susceptible to sugar end formation when subjected to  water and heat stress.

Phosphorus nutrition of potatoes
Provedor de dados: 18
Autores: Tindall, Terry A.; Westermann, Dale T.; Stark, Jeffrey C.; Ojala, John C.; Kleinkopf, Gale E.
Phosphorus (P) is an essential nutrient required by  potatoes and all other plants. Potato plant roots readily  absorb P in the form of phosphate from the soil ( water)  solution. The absorbed phosphate moves upward  and downward in the plant. Phosphorus-deficient potato  plants transfer P from older tissues to actively growing,  younger tissues.  Symptoms of P deficiency include darker green, stunted,  spindly leaves with younger leaflets that turn upward  or curl. With prolonged deficiency, plants are  small and have reduced leaf area.

Autores: Roberts, T.R.
A catalog of 79 species of freshwater fishes collected by Kuhl and van Hasselt in western Java in 1820-23 is presented, based on examination of publications, archival materials and specimens in Paris and Leiden. Archival material includes copies of their original drawings (many watercoloured) and handwritten descriptions in Latin and German or Dutch of nearly all of their new genera and species in rough drafts and in near final or final version ready for publication. A number of the descriptions, such as that of Dermogenys pusilla, include extensive anatomical and biological observations. Study of the manuscripts, drawings, and specimens has resulted in numerous reidentifications and new records, including a number of species not previously reported from...

Ultrastructure of the ascus and the ascospore wall in Scutellinia (Pezizales, Ascomycotina)
Provedor de dados: 16
Autores: Brummelen, J. van.
The development of wall layers in the ascus top and of ornamentation of ascospores is studied with the electron microscope in Scutellinia pseudolrechispora, S. umbrorum, S. patagonica, S. trechispora, and S. scutellata. In all species studied the ascus top shows a roughly delimited operculum and ascostome, a subapical ring, and special plasmatic structures just beneath the operculum. Details of these structures, as found with different methods of fixation and contrasting, are summarized. The structure and dehiscence mechanism of the ascus as described here for Scutellinia are considered to be characteristic of the family Pyronemataceae. The developmental pattern of the ascospore wall in S. pseudotrechispora is different from that found in the other...

De ontwikkeling van de vegetatie op stuifzand van de Veluwe
Provedor de dados: 16
Autores: Prach, Karel; Fanta, Josef; Lukešová, Alena; Liška, Jiří.
The colonisation of mobile sand dunes in the Veluwe, the Netherlands, was studied, as well as the spontaneous development of the vegetation into pine (Pinus sylvestris) forest. Three permanent plots were established, A, B and C, respectively, representing initial and transient stages of the succession. A list of the species is presented, and the abundance of each species in each separate plot is estimated. On account of these data the participation of higher taxonomie groups of species in each stage of the succession is described. It appears that lichens and soil algae appear first on mobile sand dunes, soon to make place for a vegetation consisting of herbs. These in turn suffer a temporary decline once the pine forest develops and forms a closed canopy....

A revision of the Malesian monotypic genus Cheilosa Bulme (Euphorbiaceae)
Provedor de dados: 16
Autores: Welzen, Peter C. van; Banka, Roy A.; Leoncito, Cecilia D.
The West Malesian genus Cheilosa Blume has been revised; the variability of the only species, C. montana Blume, will be described. Cheilosa montana combines the two former species C. montana and C. malayana (Hook. f.) Airy Shaw. Typical for Cheilosa are the presence of glands in the teeth of the leaves; thyrsoid, mainly unbranched, ramiflorous to terminal inflorescences; absence of petals; the presence of a disc; 9 or 10 stamens; 3- (rarely 4)-locular ovaries with one ovule per locule; thick-walled fruits; an aril around the seed; and endosperm. Fascicled hairs are usually present on the lower surface of the leaves, but are caducous. The excluded C. whiteana Croizat is provisionally transferred as a new species to Trigonostemon by Airy Shaw.

Het voorkomen van Rivierfonteinkruid (Potamogeton nodosus Poir.) in Nederland
Provedor de dados: 16
Autores: Coops, H.; Zant, F.M.; Doef, R.W.
Potamogeton nodosus occurs in the less dynamic parts of the rivers Rhine and Meuse, as well as in the lower parts of the river IJssel including the area around its mouth. Recently, P. nodosus has established itself in the Biesbosch area. The size of the populations of P. nodosus may vary from year to year. This is ascribed to fluctuations in the discharge of the river, as well as to fluctuations in the temperature of the water in spring.

Autores: Baas, P.
With over 80 original publications on foliar sclereids, published in the last 30 years, Dr. T. Ananda Rao is a well qualified author for a compendium on the subject. The book consists of a general and a special part. The former includes a historical and methodological introduction, a major chapter on the morphological classification of the various types of sclereids and tracheoids and their distribution patterns, and sections on their taxonomic significance as well as their ontogeny and (presumed) functions. The special part is an ‘abstract review’ of literature records and original observations on 121 families of angiosperms, arranged according to the Takhtajan system. The book is richly illustrated with line drawings as well as numerous halftone plates....

Provedor de dados: 16
Autores: Bremer, P.
The major part of the valley of the river Overijsselse Vecht has been assigned to the Fluviatile District. Of the various species which are regarded as characteristic for this valley, many have suffered a decline since 1976. Their present distribution supports the upstream delimitation of this part of the Fluviatile District, between the villages Ommen and Hardenberg.

Autores: Balgooy, M.M.J. van.
This is the final volume of the series Pacific Plant Areas, initiated by the former director of the Rijksherbarium, Dr. H.J. Lam, during the sixth Pacific Science Congress at Berkeley, USA, in 1939. Lam became the chairman of the subsection Pacific Plant Areas in 1953. The actual start of the project did not take place until 1958 when Dr. C.G.G.J, van Steenis took over the chairmanship of Dr. Lam, whom he was also later to succeed as director of the Rijksherbarium. The first volume published in 1963 by the National Institute of Science and Technology in Manila consisted of an extensive Bibliography of Pacific plant maps, scrutinously compiled by Mrs. M.J. van Steenis-Kruseman and 26 maps and text prepared by the general editor, Professor van Steenis.

Tien jaar Knolcyperus (Cyperus esculentus L.) in Nederland
Provedor de dados: 16
Autores: Rotteveel, A.J.W.
Yellow nutsedge ( Cyperus esculentus L.) was first recorded in 1981 as an agricultural pest. A considerable number of fields was found to be infested. Because the species is very damaging to agriculture legal measures were taken to restrict the dispersion and promote the control of the weed. During the eighties a monitoring system yielded much information on the development of the nutsedge populations. After 1985 the legal measures led to a decline of the species; however, the eradication was not successful on the national level. Failure in obtaining sufficient financial support led to the abandonment of the legal measures. Yellow nutsedge is now increasing again and it is expected that it will reach the status of a common weed in agriculture. Attention of...

Van vrijdag 12 tot en met maandag 15 juni 1992 is er een kamp gehouden in West-Brabant voor de floristen van FLORON. We logeerden in een kampeerboerderij te Hoeven. Er waren 16 deelnemers opgekomen, 5 mensen hebben afgezegd of zijn niet gekomen. We hebben voor deze omgeving gekozen, omdat van deze streek weinig bekend is en hier voor FLORON geen medewerkers zijn. Vanuit Hoeven vertrokken we in groepjes van 3 of 4 personen om kilometerblokken te inventariseren. Vrijdagmiddag bezochten we gebieden in de omgeving met zandige leemgronden met overgangen van zand naar klei en van droog naar nat.

Autores: Lemmens, J.W.T.J.
The scleractinian fauna of the Watamu Marine National Reserve, Kenya, was surveyed between November 1982 and April 1983. The survey yielded 276 specimens representing 113 species in 45 genera, which are presented in an annotated checklist. Four genera and 43 species are added to the the list of previously known Scleractinia for East-Africa, bringing the number of species recorded for this region to 169. This substantial increase, as well as the high coral diversity of nearby communities, suggests that further additions can be expected.

Biometric variation in Spadella cephaloptera on the Canary Islands (Chaetognatha)
Provedor de dados: 16
Autores: Broerse, Alexandra T.C.
Specimens of Spadella cephaloptera from Tenerife, Gran Canaria and Gomera (Canary Islands) were compared biometrically in regards to morphometric and meristic characters. Variation exists among the populations on the islands as well as between the islands. The populations on Gomera seem more distinct from the populations on Tenerife and Gran Canaria than the two latter are mutually. An apparent decline in the number of adults occurs in July, which is related to a decrease in the number of eggs. A shortage of food can explain the reduced fecundity of the specimens. S. cephaloptera prefers habitats protected from the influence of waves.

Progonomys Schaub, 1938 and Huerzelerimys gen. nov. (Rodentia) : their evolution in Western Europe
Provedor de dados: 16
Autores: Mein, P.; Martín Suárez, E.; Agustí, J.
In this paper the various species and populations attributed to the genus Progonomys Schaub, 1938 are revised. Valerymys Michaux, 1969 is considered to be synonymous with Occitanomys Michaux, 1969, since the type-species V. ellenbergeri (Thaler, 1966) was included in Occitanomys by Aguilar et al. (1986a). Other species from Western Europe that had been included in Valerymys cannot be transferred to Occitanomys. They are the descendants of Progonomys cathalai, for which we create the new genus Huerzelerimys, that includes the known species H. vireti (Schaub, 1938), H. turoliensis (Michaux, 1969) and H. oreopitheci (Engesser, 1989), and the new species H. minor.

The polyphyletic origin of endoparasitism in the cyclostome lineages of Braconidae (Hymenoptera): a reassessment
Provedor de dados: 16
Autores: Quicke, D.L.J.
A recent phylogenetic analysis of selected groups of cyclostome braconid wasps by Whitfield (1992) was used to investigate the evolution of biological characters associated with the transition from ecto- to endoparasitism. Incorrect methodology in character polarization and incorrect scoring of characters, and a failure to include other available data are shown by reanalysis of a corrected data matrix to compromise Whitfield's conclusion that endoparasitism evolved twice in his selected set of taxa. Greater rigor and the use of additional informative characters are advocated to obtain more robust phylogeny upon which conclusions regarding biological evolution can be more reliably based.

Review
Provedor de dados: 16
Autores: Keßler, Paul J.A.
As almost half of the Malesian species of Meliaceae are found in the genus Aglaia, we are glad to receive a sound monograph published for this ecologically so important genus. The format can be characterized as ‘classical’, with chapters on taxonomic history, morphology, floral biology and pollination, fruit and seed-dispersal, germination, cytology, variation and distribution, besides the pure taxonomic revision. The first part would have been a little more attractive for the reader if certain characters had been drawn, especially some of the very intricate or minute features as scales and stellate hairs which have been used intensively in the key and for which, unfortunately, every botanist seems to have his own definition. The 105 species are described...

The genera of the superfamily Pterophoroidea are redescribed. Three new genera are described: Dejongia, Stockophorus and Shafferia. The characters of the genera and their states are translated into a data matrix. A majority rule consensus tree composed with PAUP serves as a basis for a phylogenetic analysis. A cladogram, representing the views of the author, based on the data acquired, is presented with argumentation. The evaluation of the characters is discussed. A new subfamily is erected, the Deuterocopinae. The Pterophorinae are redefined. The Platyptiliinae are synonymized with the Pterophorinae. The Macropiratidae, considered by Minet (1991) a subfamily or a genus of the Pterophoridae, has been raised to family rank, and is placed as the sister group...

The taxonomic significance of the short-shafted mesotriaene reviewed by parsimony analysis: validation of Pachastrella ovisternata Von Lendenfeld (Demospongiae: Astrophorida)
Provedor de dados: 16
Autores: Maldonado, Manuel.
The spicule complement of a demosponge specimen collected from the Atlantic coast of Spain was noted to be similar to that of Pachastrella monilifera, but particularly characterized by the presence of short-shafted mesotriaenes. After detailed examination, it was concluded that the specimen undoubtedly belonged to the species Pachastrella ovisternata Von Lendenfeld, 1894. For a long time, this species has been regarded a synonym of Pachastrella monilifera Schmidt, 1868. Examination of this new specimen showed that Pachastrella ovisternata was a valid species of the genus Pachastrella. Moreover, it denoted the real existence of mesotriaenes in this genus. The parsimony analyses indicated that the species Yodomia perfecta, traditionally assigned to the genus...

The kernel of this book consists of an enumeration of some 1600 publications of importance to the flora of the Mascarenes (East of Madagascar; main islands Réunion, Mauritius, Rodrigues), arranged alphabetically by author. Fairly often a short note is given on contents and importance. Counterpart to this enumeration is an extensive Subject Index which gives many different entries to the first part. The practical value of a book like the present one depends primarily on its completeness, secondarily on its selectivity. As to the first point, this is not easy to check. Comparison with the literature on some families the reviewer is acquainted with gave the impression that the enumeration is still (rather?) incomplete. Therefore, we may hope that future, ever...

A Late Pliocene rodent fauna from Alozaina (Malaga, Spain)
Provedor de dados: 16
Autores: Aguilar, J.P.; Michaux, J.; Delannoy, J.J.; Guendon, J.L.
In this paper 11 species of rodents are described, that have been found in the fossiliferous karst fissure of Alozaina (Malaga, Spain). Three species of Stephanomys (Murinae) are present in this fauna: S. thaleri, S. minor, and the new species S. prietaensis. The latter exhibits a lesser degree of evolution than Stephanomys balcellsi from Valdeganga 7 and Islas Medas. The association of rodents from Alozaina is a new one for the Upper Pliocene in Spain. It indicates that the locality of Alozaina is younger than Moreda 1B and Rambla Seca Ab, and older than Valdeganga 7.

An early note on the occurrence of the Magnificent Frigate Bird, Fregata magnificens Mathews, 1914, in the Cape Verde Islands: Columbus as an ornithologist
Provedor de dados: 16
Autores: Hartog, J.C. den.
The importance of ornithological observations with respect to Columbus' discovery of America as recorded in the "Diario del descubrimiento" is recognized. The fact that his first and crucial crossing of the Atlantic coincided with the autumn migration may have contributed to its success. Columbus' log contains the first historical record of the [Magnificent] Frigate Bird, Fregata magnificens Mathews, 1914, in the Cape Verdes, with a surprisingly accurate description of its characteristic habits.

The laophontid genus Loureirophonte Jakobi, 1953 (Copepoda, Harpacticoida) *
Provedor de dados: 16
Autores: Fiers, F.
So far, only three species are known in the laophontid genus Loureirophonte Jakobi. In the present contribution five new species are described, and two species formerly attributed to other laophontid genera (Paraiaophonte subterranea Lang and Laophonte cesareae Por), are allocated to Loureirophonte. A redescription of L. cesareae, based on type-material, is included. Relying on the increased understanding of loureirophontid morphology, the diagnoses of L. catharinensis, type-species of the genus, and L. paranaensis are amended. Finally, three species-groups are defined within the genus: the catharinensisgroup, the cesareae-group and the subterranea-group.

Bird dispersal of loranthaceous mistletoes to remote Pacific islands: symbiosis in default
Provedor de dados: 16
Autores: Barlow, Bryan A.; Schodde, Richard.
Mistletoes of the family Loranthaceae have characteristically low dispersibility. Whereas the family is represented by c. 400 species on the continental masses and intervening archipelagos on the western Pacific rim, and by a similar number in South America, only a few species have reached remote South Pacific islands. Recent bird dispersal of Ileostylus micranthus from New Zealand to Norfolk I (c. 700 km) is comparable in distance with island-to-island bird dispersal in the most widespread species, Decaisnina forsteriana, from New Guinea to the Marquesas in Quaternary time. Once established in island communities, even species of generally low dispersibility may have an increased probability of further waif dispersal. For mistletoes a shift in avian...

Review
Provedor de dados: 16
Autores: Kalkman, C.
The title of this volume is a bit misleading. Apart from Rosaceae also the Chrysobalanaceae (two autochthonous species) and the Neuradaceae (one species) are treated. The bulk, however, concerns the Rosaceae in the more restricted and generally adapted sense. In India 32 genera of this family, comprising some 450 species, are autochthonous. Nine genera are treated in this volume, four ( Aruncus, Neillia, Sorbaria, and Spiraea) belonging to the subfamily Spiraeoideae and five ( Agrimonia, Alchemilla, Filipendula, Geum, and Sanguisorba) to the Rosoideae. Most of the genera have only few species (1 to 6) in India but Spiraea has 31 and Alchemilla has 26. The second part of the series is now in production and will contain studies on Rosa, some Maloideae and...

This monograph is a fine example of the thorough work we may expect from Wageningen in general, from its author in special. What present-day botanist gets the opportunity to study the material of his group from about a hundred herbaria all over the world and more than half the number of species in nature! Each species gets: nomenclature, typification and literature; an extensive description about 1 page long; short paragraphs on Distribution and Ecology; a citation of (part of) the specimens studied, including the precise locality and the herbaria; sometimes one or a few note(s); full-page drawing and map.

Provedor de dados: 16
Autores: Boer, A.J. de.
A new concept is proposed for the cicad genus Aedeastria De Boer, 1990, so that ten species can be added, bringing the total number of species to twelve. Of these ten species added to the genus, two (A. latifrons (Blöte) and A. digitata (Blöte)) are redescribed and transferred from Baeturia Stål, while eight species (A. bullata, A. cheesmanae, A. dilobata, A. hastulata, A. kaiensis, and A. moluccensis, A. obiensis, A. waigeuensis) are described as new. A key to the males of Aedeastria is presented. Aedeastria belongs to a group of Australian and New Guinean genera, defined earlier as the “Baeturia and related genera complex” and is very closely related to the genus Thaumastopsaltria Kirkaldy of that complex. Though no cladogram is presented, the...

Tolypella prolifera is a rare stonewort-species. Its distribution is centred in the Netherlands. Recent investigations in the province of Zuid-Holland show that it is less rare than was previously known. It is usually found in narrow, frequently cleaned ditches on clay soils, growing in shallow water with comparatively low amounts of potassium and phosphate. A frequent and thorough cleaning of the ditches by which all vegetation and organic matter is removed, is important for its survival. Tolypella prolifera then colonizes the barren clay soil.

Review
Provedor de dados: 16
Autores: Balgooy, M.M.J. van.
The recent surge of interest in plants growing over serpentine is reflected in a spate of papers on the subject, so much so that it is difficult to keep track of what has been published. The present volume is an attempt in that direction. Both editors can glory in a long career of research on serpentine plants. The term serpentine is often used to denote a wide range of ultramafic rocks which are characterized by high concentrations of toxic heavy metals (Cr, Co, Ni), high Fe and Mg and low Ca and Si concentrations. The vegetation growing on serpentine often shows a striking contrast with surrounding vegetations on different soils. The stature is mostly low, xeromorphic structures prevail and floristic diversity is usually low, although endemism may be...

On the history and type specimens of the Cape Verde Cane Warbler Acrocephalus brevipennis (Keulemans, 1866) (Aves, Sylviidae)
Provedor de dados: 16
Autores: Hazevoet, C.J.
The Cape Verde Cane Warbler Acrocephalus brevipennis was first described in 1866, and again in 1871 and 1883. These descriptions were all made after specimens from the same series. A type specimen was never designated and only one syntype from the original series can be traced today. The taxonomic history of the species is discussed and the single remaining syntype described. The present status and distribution of the species are briefly discussed.

Neocyclops Gurney from Brazilian sandy beaches (Copepoda: Cyclopoida)
Provedor de dados: 16
Autores: Lotufo, Guilherme Ribeiro; Falavigna da Rocha, Carlos Eduardo.
Neocyclops medius Herbst, 1955 and Neocyclops vicinus (Herbst, 1955) are redescribed from intertidal interstitial water of sandy beaches along the Brazilian coast. The male of N. vicinus is described for the first time. Neocyclops vicinus can be easily distinguished from N. medius by the relatively longer caudal rami, the presence of a mandibular palp, and the sexually dimorphic antenna. This study revealed the leg 4 endopodite segments 2 and 3 as being fused in both species. The terminal segment of the 2-segmented leg 4 endopodite of the copepodite 5 does not differentiate into 2 distinct segments during the molt to adult. The plane of fusion is marked by a thin and incomplete line on the frontal surface. This scar was erroneously interpreted as a...

Cnesmocarpon (gen. nov.), Jagera, and Trigonachras (Sapindaceae—Cupanieae): Phylogeny and systematics
Provedor de dados: 16
Autores: Adema, F.; Ham, R.W.J.M. van der.
Cladistic analyses of pollen-morphological, leaf-anatomical and macromorphological data of Jagera, Trigonachras, and several new species lead to the conclusion that a new genus, Cnesmocarpon, has to be described (see the Taxonomic Part on p. 195). Two pollen types are described, one including Cnesmocarpon, the other including Jagera and Trigonachras. The morphologies of these pollen types suggest different harmomegathic systems: nonapertural and apertural folding respectively. The ornamentation of Cnesmocarpon pollen resembles that of several other Cupanieae genera. The scabrate ornamentation of Jagera and Trigonachras pollen, often provided with hair-like appendages, is unique in that tribe. Leaf-anatomically Jagera is characterised by the presence of...

Provedor de dados: 16
Autores: Gittenberger, E.
To provide background information for a proposal to the International Commission on Zoological Nomenclature to suppress five subjective senior synonyms of Trochoidea geyeri, the synonymies of this and some other hygromiid species are given. The nominal taxa that are dealt with concern species that are conchologically more or less similar. These species were studied to minimize the risk that even more unused senior synonyms of T. geyeri would be discovered, which would require an additional ruling of the Commission. Distributional data and short conchological diagnoses are added to increase the usefulness of the present paper.

De Franse aardkastanje [Conopodium majus (Gouan) Loret] nadert de Nederlandse grenzen
Provedor de dados: 16
Autores: Weeda, E.J.
Op 14 mei 1988 toonde Onno de Bruijn me bij Bentheim in Nedersaksen een aantal planten van een Schermbloemige, die daar door enkele Twentse floristen waren opgemerkt en die niet met zekerheid op naam konden worden gebracht. Aanvankelijk dachten we aan Meum athamanticum (wat in vergelijkbare gevallen wel vaker schijnt te gebeuren). Pogingen om één plant in haar geheel te verzamelen, mislukten door de hardheid van de kalkgrond ter plaatse: een bloeistengel zonder ook maar een aanduiding van een wortel was al wat we in handen kregen. Dat voedde de veronderstelling dat de plant weieens een knol zou kunnen bezitten. Bij raadpleging van Tutins ‘Umbellifers’¹ bleek dat in dat geval maar twee opties openbleven: Aardkastanje ( Bunium bulbocastanum) en Franse...

The scientific career of the zoologist Max Wilhelm Carl Weber (1852—1937)

It is shown that the pinnacle of Max Weber’s scientific career was the organization and leadership of the Siboga Expedition to the former Netherlands East Indies (now Indonesia) in the years 1899—1900. Before that time, as Professor of both General and Special Zoology at the University of Amsterdam, he had devoted his research mainly to the anatomy of mammals, which resulted in the fundamental reference work Die Säugetiere published in first edition in 1904. Just before his departure with the Siboga Expedition Weber was appointed Extraordinary Professor of Special Zoology in Amsterdam. This gave him more time to edit the results of the Siboga Expedition and for taxonomic studies, especially on the fishes of the Indo-Australian Archipelago. Nevertheless he...

Phylogeny and biogeography of the Niphargus transitivus group of species (Crustacea, Amphipoda)
Provedor de dados: 16
Autores: Sket, Boris; Notenboom, Jos.
The Niphargus transitivus group includes 12 groundwaterdwelling species. It is defined by an upright body position during locomotion, a small, stout body with short appendages, except for long coxae and dactyli, coxae V-VI equilobate or posterolobate, accessory flagellum subject to reduction, and the body endowed with adaptations for volvation ( = ability to enroll into a ball). The biogeography of this southeastern European group of species is discussed and a cladistic analysis of the group is presented. Some cases of parallel character evolution in groundwater amphipods are mentioned. The inference of biogeographic and phylogenetic information in elucidating the evolutionary history of the group is hampered by inconsistency of the data. One of the...

This paper presents an analysis of the Kislangia-material from the localities of Almenara 1 (= Casablanca 1) and Galera 2 (Guadix-Baza Basin). This revision led to the recognition of a new species, Kislangia gusii, distinguished from the Central European K. rex, to which most of the Spanish populations were referred until now. Two different lineages of Kislangia existed during the late Villanyian in Europe, one leading to K. gusii and the other one leading to K. rex. K. gusii is compared with other samples, from French and Spanish localities.

Autores: Luegmayr, Eva.
Pollen of 30 species and 12 hybrids (88 samples in total) of Hawaiian Cyrtandra, covering all 6 sections recognized on the Hawaiian archipelago, was examined using light, scanning and transmission electron microscopy. Hawaiian Cyrtandra is stenopalynous. The pollen grains are binucleate, isopolar, small-sized and 3-colporoidate (very rarely 4-colporoidate). In equatorial view they are spheroidal, in polar view circular or semiangular. The tectum is mostly microreticulate with brochi of different sizes (heterobrochate), very rarely reticulate or perforate. Supratectal elements are lacking. Some variation can be observed in number and diameter of the lumina. Palynological features of most of the investigated taxa tend to overlap and thus are not very helpful...

Peltopus, and sect. Uncifera (all mainly occurring in New Guinea). Together these include 110 species and 9 subspecies. Fortyseven species and 4 subspecies are new; they are either described in this revision or in precursors to this revision. The genus Dactylorhynchus is reduced to Bulbophyllum. Keys to the species, as well as synonymy, descriptions and illustrations of each species are provided. Some aspects of the morphology of the plants are discussed. A cladistic analysis of each revised section is given. A method to select the closest outgroup species from a number...

On the only Greek Sphincterochila species, two Libyan close relatives, Cerigottella subgen. nov., and an extended diagnosis of the Sphincterochilidae (Mollusca, Gastropoda Pulmonata)
Provedor de dados: 16
Autores: Gittenberger, E.
From Greece, based on conchological characters, a single, endemic Sphincterochila species has been reported about a century ago. Its occurrence is still thought to be restricted to the islet of Andikithira. The structure of the genitalia, hitherto unknown, demonstrates that it concerns a separate species indeed; its closest relatives known are two Libyan species. These three species differ from the Sphincterochila species studied so far most clearly by the stimulatory organ, inserting not on the genital atrium but far more distally on the vagina. They are classified within Cerigottella subgen. nov.

The porcupine Hystrix suevica Schlosser, 1884 from the lower Turolian of Crevillente 2 (Spain)
Provedor de dados: 16
Autores: Montoya, P.
The fossil record of the genus Hystrix is rather scarce, and little is known about its origin. Its presence in Crevillente 2, a well-dated Lower Turolian (MN11) Spanish locality, is an important fact because, from a stratigraphic point of view, it is one of the oldest references of this genus. The comparative study of the remains from Crevillente 2 reveals the presence of a small species, Hystrix suevica, which lived in Europe from Middle Aragonian to Early Turolian time. In most recent revisions of the genus Hystrix, this species has not been taken into account. H. suevica shows undeniable morphological affinities with H. primigenia. The latter was a large-sized Hystrix, which spread over Europe from Middle Turolian to Late Pliocene time, reaching Africa...

Provedor de dados: 16
Autores: Raam, J.C. van; Maier, E.X.
Until 1930, the stonewort Nitella translucens was known from six localities the Southern and Eastern parts of the Netherlands. In the following period (1930—1980) the species disappeared from these localities, but was found to grow profusely on nine new ones, partly in the same areas, but also in the central part of the Netherlands. Particularly large populations occurred in fens. Since 1970 it suffered a serious decline; at present the species appears to have survived on four localities only, mainly in ditches. Data on all known localities, ecology and phytosociology are presented. [Article 3 in this series has been published in Gorteria 18 (1992): 33—39.]

Eleven seagrass species were found in South Sulawesi, Indonesia. Seagrasses occurred in five different habitats, i.e. intertidal terrigenous mudflats, shallow terrigenous sandy bays, coastal reef flats, reef flats of patch reefs, and sandy reef bases, from the intertidal to a maximum depth of 35 m. Thalassia hemprichii and Enhalus acoroides were the dominant constant species of stable environments (permanently present in climax vegetations). Cymodocea rotundata, Halodule uninervis and Halophila ovalis were the dominant pioneering species in the area. A considerable number (117) of macroalgal taxa were found associated with seagrass vegetation, but only 13 of these were found exclusively in association with seagrasses.

Seasonal variation in copepod abundance in relation to other zooplanktonic groups in the northwestern Mediterranean
Provedor de dados: 16
Autores: Kouwenberg, Juliana H.M.
Abundance of adult copepods and late copepodid stages from the upper 50 m in the Golfe du Lion (N.W. Mediterranean) was studied by the author in 1986, 1987, and 1988 for each season. Altogether 87 stations at 22 fixed locations were sampled in the frame of the multidisciplinary French/Spanish programme Pélagolion/Leopel in the near-coastal region (≤ 25 m bottom depth), the Rhone dilution zone, the neritic region (≤ 200 m bottom depth), and the oceanic region (200—2000 m bottom depth). Abundance of other zooplanktonic groups was estimated and total zooplankton biomass was determined for the upper 50 m. Copepod abundance was highest during September 1986 (all regions) and July 1987 (neritic). Total biomass was highest during July 1987 and May/June 1988,...

Zur taxonomischen und phylogenetischen Bedeutung der Feinstruktur der Eischale der Parnassiinae (Lepidoptera: Papilionidae)
Provedor de dados: 16
Autores: Häuser, Chr.L.; Naumann, C.M.; Kreuzberg, A.V.-A.
The chorion surface structure of the eggs of 31 species of the subfamily Parnassiinae was studied by SEM on a comparative basis. The eggs are briefly described and taxonomic characters are illustrated. The eggs of all examined species of the genus Parnassius possess a very thick, externally highly sculptured chorion, whereas in all other genera of the Parnassiinae the eggs are externally smooth, as in most Papilioninae. The thickened, externally sculptured chorion is regarded as an autapomorphy of the genus Parnassius, which probably is linked to the hibernation of the fully developed first instar larvae within the egg shell.

Autores: Verkley, Gerard J.M.
The ultrastructure of the ascus apical apparatus is compared in 19 species of the Hymenoscyphoideae, currently placed in seven genera. The ascus wall consists of an outer layer of two strata, and an inner layer of also two, and in one species of three strata. At the apex only the inner layer increases in thickness. On the basis of the general morphology and PA-TCH-SP reactivity pattern of the apex five main groups are recognized. A further division into subgroups is also outlined. The most important diagnostic features used in the analysis are the relative development and the reactivity pattern of the apical thickening, the occurrence of an annular protrusion, the structure and the reactivity pattern of the annulus, and the apex maturation pattern.

G. flava is designated as the type species of the genus. Baeturia minuta Blöte, 1960 is synonymized with Guineapsaltria flava. The phylogeny of Guineapsaltria is discussed and some remarks are made on its phylogenetic relationships with other New Guinean and Australian tibicinid genera. A key to the males...

Review
Provedor de dados: 16
Autores: Leenhouts, P.W.
The Goodeniaceae is a fascinating family, nearly exclusively Australian. It comprises 11 genera with some 400 species. Most of the genera are small to medium; the largest genera are Scaevola with nearly 100 species and Goodenia with 178 Australian species. The closely allied Brunoniaceae is monotypic, strictly Australian. By now the format of this series is well known. To its special attractions belong the fine colour photographs, especially in a family like the present one. Furthermore, it is illustrated with simple but clear habit pen-drawings, drawings and photographs of indumentum types, hairs, and seeds, and for every species a small map with the distribution within Australia. These maps, and the citation of up to five representative specimens per...

Phylogenetic and systematic position of Sesarma rubripes Rathbun, 1897 (Brachyura: Grapsidae)
Provedor de dados: 16
Autores: Niem, V.H.
The American grapsid crab Sesarma rubripes, classified as Metasesarma rubripes by Rathbun (1918), was compared with M. rousseauxi, the type species of Metasesarma, and was found to be different in a number of characters. On the other hand, S. rubripes is very close to those species of American Sesarma that are considered to be members of the subgenus Chiromantes. The characters common to S. rubripes and the American Chiromantes can be interpreted as synapomorphies by means of an outgroup comparison. Aratus pisonii and the West African Sesarma elegans are further members of the group in question and both share special derived characters with S. rubripes. As a consequence, S. rubripes should be returned to the genus Sesarma. It is recommended, however, to...

Data from this century on the distribution of Caltha palustris and Hottonia palustris are used tot illustrate the role of volunteers in a monitoring scheme. Actual patterns in the distribution of the two species are discussed. About 40 percent of these data has been sampled by volunteers. It is demonstrated that both Caltha and Hottonia showed a decline in the period 1975—1989. In contrast to Caltha, the occurrence of Hottonia is strongly linked to areas with seapage water.

East Palaearctic Cordulegastridae from the former Lieftinck collection are identified. Two Neallogaster species are described and figured. Neallogaster is supposed to consist of two speciesgroups. Cordulegaster lunifera and C. pekinensis are redescribed and figured. A single female from Central China belongs to C. jinensis. It is assumed that these three Cordulegaster species belong to a separate supraspecific taxon. A single male Cordulegaster from 'Tsingtau" is not conspecific with other cordulegastrids known from China; it resembles the European C. boltonii and will be described as a new species in a revision of the C. boltonii species-group. It is emphasized that the cordulegastrid fauna of the East Palaearctic is still insufficiently known.

On the basis of both detailed distributional field studies and morphological analyses, a revision of the polytypic species Albinaria hippolyti from Central and Eastern Crete is presented. True subspecies are distinguished from mere geographic varieties by the presence of narrow hybrid zones. Using this criterion, four adjoining subspecies are recognised: A. h. hippolyti (Boettger, 1878), A. h. aphrodite (Boettger, 1883), A. h. holtzi (Sturany, 1904) and A. h. harmonia subspec. nov. Additionally, two geographically isolated and conchologically distinctive forms are also treated as subspecies: A. h. arthuriana (Boettger, 1878) and A. h. asterousea subspec. nov.

The Kimberley is an extremely rugged area in NW Australia extending over 170,000 square kilometers. It has always been one of the biologically unknown wilderness areas of the world. The presence of rainforest in this part of the continent was not even known before 1965. In 1986 a three-year exploration was started to unravel its mysteries. The results of this study are laid down in the present volume which deals with a variety of subjects, such as: soil, vegetation, floristics, landsnails, scorpions, spiders, insects, amphibians, reptiles, birds, mammals and nature conservation. The forest is of the monsoon type and consists of a number of patches varying from a clump of a few trees to 100 hectare. In many places these patches are continuous with mangrove...

All species and subspecies of the Hesperiidae known from the Philippines are listed and their distribution across the islands, preferred habitats and flight habits are indicated. By far the richest habitat is the primary lowland forest. In view of the high rate of deforestation it is estimated that 50% of the hesperiid species is endangered and may become extinct over the next 10 to 15 years. With 151 species the Philippines is considerably poorer than Borneo (214 species), but much richer than Sulawesi (84 species). In terms of endemicity, however, the Philippines is with 35 endemic species (23.2%) relatively much richer than Borneo (12 species, 5.6%), and almost as rich as Sulawesi (20 species, 23.8%).

Keys are given to the genera of geophytic Aroideae in Australasia and to the species of Typhonium. Apparent affinity between two new Australian Typhonium species and the Indian genus Theriophonum is noted. It is suggested that Australasian representation of Areae is mostly autochthonous and ancient rather than immigrant and comparatively recent in origin.

The Australasian/Malesian group of genera Amylotheca, Cyne, Decaisnina, Lampas, Lepeostegeres and Loxanthera is reviewed. Particular attention is given to the species of the Malesian region, as a precursor to a treatment of Loranthaceae for Flora Malesiana. The genera are part of a floristic element of Gondwanan derivation which has diversified in the southeast Asian and western Malesian region, and has reached the Papuasian/Australasian region from the west following the establishment of Charles’s Line. The six genera comprise 46 species ( Amylotheca 4, Cyne 6, Decaisnina 25, Lampas 1, Lepeostegeres 9, Loxanthera 1). Along with the Australian genus Lysiana (8 species) they form a natural group with tribal or subtribal status. Major centres of species...

State of affairs regarding Flora Malesiana: progress in revision work and publication schedule
Provedor de dados: 16
Autores: Roos, M.C.
The last two years I have made an inventory of the Flora Malesiana network and the revision work remaining. In total the network comprises c. 130 contributors working on 90 of the remaining 135 families (see Appendix). From an estimate by specialists on species numbers of vascular plants in Malesia it appears that the Malesian flora is far richer than traditionally assumed, amounting to some 42000. This means that the flora comprises c. 13% of the world flora of vascular plants on c. 2% of the land surface. For the ferns the figure is probably up to 30% of the total number of species. Subsequently, all specialists revising taxa for Flora Malesiana were sent a questionnaire asking information on progress, possible bottlenecks, and the expected date of...

This thesis is a continuation of the study of a linear, mitochondrial plasmid of Claviceps purpurea. The molecular expression and function of this plasmid were studied. It remained difficult to identify the terminal proteins of these linear genetic elements. Experiments to transfer linear plasmids between strains of Claviceps purpurea and Neurospora crassa showed that such transfers do not occur. The author concludes that the study of the linear plasmid of Claviceps purpurea strongly suggests that these genetic elements are most probably of viral origin.

Over het komen en gaan van de Glanzige ooievaarsbek (Geranium lucidum L.) in Nederland
Provedor de dados: 16
Autores: Weeda, E.J.
Although the Netherlands lie within the rough limits of the area of Geranium lucidum, this species is no native of this country. In the past century it was recorded at some country-seats in the province of Utrecht, but it was not recorded there anymore in the present century. Recently two localities were discovered in the coastal area. Of one of these, in the inner dunes near Overveen (Haarlem), a vegetation ‘relevé’ is given. The plant thrives here for the fourth year in succession, and the conditions seem rather favourable for its survival.

Pentastemonaceae
Provedor de dados: 16
Autores: Duyfjes, Brigitta E.E.
The taxonomic position and rank of the only genus Pentastemona has been under discussion since Van Steenis (1982) described the genus in the Stemonaceae. Dahlgren et al. (1985) found it highly distinctive and suggested it worthy of family rank. Later on more material of P. sumatrana and P. egregia has become available facilitating a more accurate description of the androgynoecium. Conspicuous differences from the Stemonaceae, viz. the inferior ovary, the five pouches caused by the fusion of connectives and stigma (especially well-developed in P. egregia), the berry-like fruit and the exotesta (sarcotesta) of the seed, warranted the distinction of a separate new family for the genus. Note — Pentastemona is the first genus in the Monocotyledons with normally...

Six species of Copepoda Poecilostomatoida of the families Myicolidae, Sabelliphilidae, Lichomolgidae, and Mytilicolidae are recorded from six different species of intertidal bivalves in the East Scheldt (The Netherlands), a branch of the southern bight of the North Sea. One bivalve species may harbour more than one species of copepod, and one copepod species may use more than one species of bivalves as host. Mytilicola orientalis and Myicola ostreae are new to the North Sea, both being undoubtedly carried in accidentally with oriental oysters, successfully introduced for mariculture.

Pleurotus ostreatus and P. pulmonarius, wood-destroying and edible basidiomycetes, were the subject of an ecophysiological study with regard to the connection between water household in the fruitbody and sporulation. Field observations were combined with controlled laboratory experiments on cultivated fruit-bodies. In the field it appeared that when it is about freezing point during the day, sporulation is mainly determined by temperature factors. In milder periods, water content of the fruit-bodies is the major factor influencing the sporulation. There was not found a daily pattern in sporulation nor endogenic rhythm. In cultivated fruit-bodies, the field observations were confirmed as to the influence of relative humidity for the duration of the...

Determination of Prostaglandins in the Colostrum of Dairy Cattle by Thermospray High-Performance Liquid Chromatography-Mass Spectrometry.
Provedor de dados: 19
Autores: FUKUSHIMA, Michihiro; NAKANO, Masuo; ENDO, Tsuyoshi; NEGISHI, Takashi; 福島, 道広.
A thermospray high-performance liquid chromatography-mass spectrometry (TSP HPLC-MS) method is described for the analysis of prostaglandins (PGs) E1 and E2, which have several physiological actions at the trace level. HPLC separation was carried out on a reversed-phase column by using 50mM ammonium acetate (pH 4.5)-acetonitrile (7:3, v/v) as the mobile phase at a flow rate of 1.0ml/min. In MS detection, the vaporizer temperature was set at 220°C and the ion-source block temperature at 264°C. The mass spectra obtained from PGs typically exhibited the [M+NH4]+ ion (5 to 30% relative intensity) and several fragment ions due to sequential losses of water from both the [M+H]+ and [M+NH4]+ ions. PGE1 (46.9ppb) and PGE2 (1.9ppb) in the colostrum of dairy cattle...

Estudio sedimentológico y mineralógico en Bahía Chile, Isla Greenwich, Islas Shetland del Sur (Antártida)
Provedor de dados: 20
Autores: Villacrés, J.; Goyes A., P.
En este trabajo se presentan los resultados de los análisis realizados sobre los sedimentos superficiales de fondo en Bahía Chile, Isla Greenwich, desde el punto de vista granulométrico y mineralógico. En un total de 18 muestras del área se observa una predominancia de limos muy mal seleccionados, platicúrticos y con asimetría hacia los tamaños finos. Mineralógicamente, se observa mayor concentración de minerales livianos sobre los pesados, con altos porcentajes de fragmentos de rocas igneas, deduciéndose que son sedimentos inmaduros y que el área fuente se encuentra en una zona cercana. Los sedimentos depositados en la bahía son de orígen mixto: Procedentes de la erosión de las formaciones costeras y en menor porcentaje, del aporte de organismos marinos....

Autores: Villón, C.; Balladares, M.
En 1992 fueron visitados los puertos de Esmeraldas, San Mateo, Manta, Anconcito, Sta. Rosa, Engabao, Playas y Puerto Bolívar, obteníendose información de la actividad pesquera artesanal mediante un sistema de entrevistas aplicado a 2000 embarcaciones, las que en conjunto forman la flota operativa de los ocho puertos antes mencionados. El desembarque total acumulado durante 1992 se estimó en 38632,8 t, fluctuando entre 897 t en Playas y 9006 t en Anconcito. Este desembarque total acumulado fue superior al realizado durante los años 1990 y 1991. El esfuerzo pesquero se mantuvo casi constante en los puertos visitados durante 1992, sin embargo el número de botes activos registrados al día del muestreo presentó una variación significativa.

The composition of the fleet is analyzed. The boats range 50-200 HP of engine and have 9-16 m in length overall. Most of the boats have been improving their equipment (echosounders, new engines) since 1980. An inverse relationship was found between sea surface temperature and CPUE as measured by mackerel catch permit time spent on fishing gounds. Yields are negligible over 20°C with a optimum of 20°C.

Consideraciones sobre la alimentación de la caballa con especial enfasis en la depredación de huevos y larvas de peces
Provedor de dados: 20
Autores: Pájaro, M.
Adult and juvenile fish inter and intraspecific predation may be an important source on these first development stages. In this work, adult and juvenile mackerel samples from two areas of Buenos Aires province, one south of Cape San Antonio and the other near Mar del Plata city were analyzed. An important anchovy postlarvae ingestion in both regions considered was observed. A high number of mackerel eggs in the stomach contents from adults was identified. This evidence of cannibalistic behaviour in the argentine mackerel is the first of its kind made in this species and allows to suggest that embryo mortality due to cannibalism might constitute and important percentage of the total embryonic mortality.

This volume of tuna statistics for the West Indian Ocean (WIO) is the second to be based on the "New tuna" program.  It includes the figures for 1992 as well as 1993.  Due to the necessity of rapidly publishing 1993 statistics only one volume has been produced for the whole year and not one for each quarter.  In future the whole year and not one for each quarter.  In future the system of publishing a Tuna Bulletin each quarter will be reverted to.  Due to the inclusion of trips which started at the end of 1992 but which finished in early 1993 the 1992 total catch has been revised upwards from 273,852 MT. published in the last Tuna Bulletin to 278,218 MT.

Mackerel from SW Atlantic (22° -39°S) and the coast of Cataluña (42° 30'N) were compared by analizing both morphometric and meristic characters. A multivariate analysis, i.e. principal components was used. The growth curves corresponding to mackerels from different regions (Canarias, North of Chile, Mar del Plata and Rincón in Argentine) were also compared, as well as the mean length at ages 1 and 2 (Mar del Plata- Cataluña, Rincón- Cataluña). Significant differences in the growth were found between two groups. The first group was integrated by three SW Atlantic population (Brasil, Mar del Plata, Rincón), which possible conform a subspecies of Scomber japonicus. The second one was represented by the coastal mackerel off Cataluña.

Au large de la côte sénégalaise, il y a deux grandes circulations: (1) le courant nord-équatorial qui prend naissance vers les îles du Cap-Vert et qui transporte les eaux froides du courant dit des Canaries vers l'ouest; (2) le contre-courant équatorial transportrant vers l'est les eaux chaudes et salées formées sur le bord sud du courant nord-équatorial.  Prés de la côte, les courants de surface ont une forte variabilité due à la succession du courant des Canaries et du contre-courant équatorial. Les courants de marée sont...

Geomorphology of the Kenyan Coast: Not as a Result of Sea-Level Change Alone
Provedor de dados: 20
Autores: Abuodha, P.A.W.
The coastal setting and the geology control the geomorphology on the Kenyan coast. The evolution of the physical environment has also been influenced by climate, wave and tidal regime, sedimentation and river discharge. The shore terraces of Kenyan coast correspond to eustatic movements of sea level. There seems to be evidence of a high water level during the late Pleistocene. For the lower terraces a Holocene age is suggested. During the Pleistocene, sea level fluctuations associated with glacial / interglacial phases left well developed raised platforms and beaches. The Kenyan coast has a strong tectonic influence and it is difficult to describe the coast in terms of emergence or submergence only. It can therefore be concluded that the geomorphology of...

Autores: Castro, R.; Rosero, J.
The aim of this study was to determine the characteristics, dimensions, materials used in the fishing gear and boats currently used by the artisanal fisheries along the ecuadorian coast. Three provinces were visited (Guayas, Manabí and Esmeraldas), in which the artisanal ports with the greatest fishing effort and landings along the coast are registered. Interviews with the fishermen, identification of the fishing gear and certain measurements were taken to obtain the information on the desing, dimensions and materials used in the fishing gear as well as the techniques and principal fishing zones. Aditionally the diversity of the fishing boats was noted varying from small sailing rafts to the fast-glass boats with outboard engines.

Autores: Avit, J.-B.L.F; Luquet, P.
Une expérience sur le mode d'alimentation du mâchoiron,chrysichthys nigrodigitatus,élevé en cage-enclos en milieu lagunaire (lagune EBRIE ,Côte d'Ivoire),a été menée pendant 5 mois ,d'octobre à mars.Ont été comparées les performances zootechniques permises par les deux modes de distributions suivants:manuelles ou en libre service. Ce dernier mode de distribution de la nourriture, en situation d'iso-ingestion journalière, améliore la croissance pondérale et l'indice de consommation. les deux méthodes permettent, en outre de mettre en évidence les mêmes variations mensuelles de performances.

Cycle sexuel et fécondité du mâchoiron Chrysichthys nigrodigitatus en lagune Ebrié, Côte d'Ivoire.
Provedor de dados: 20
Autores: Otémé, Ziriga Josué.
L'évolution saisonnière du développement des gonades chez les femelles de Chrysichthys nigrodigitatus en lagune Ebrié (Côte d'Ivoire) a été étudiée sur un cycle annuel de reproduction. Sept stades macroscopiques de maturation des gonades ont été identifiés. Ces poissons ne pondent qu'une seule fois durant une saison de reproduction qui s'étend de juillet à novembre. La fécondité potentielle varie entre 4878 et 87724 ovocytes et 5438 et 36257 ovocytes respectivement pour le milieu naturel et le milieu d'élevage. La corrélation entre la fécondité et la longueur du poisson est légèrement plus marquée que celle entre la fécondité et et le poids des gonades

Cette étude présente la morphologie récente de l'embouchure du fleuve Bandama à Grand-Lahou. A l'interface eau/sédiment apparaissent des chenaux et des hauts fonds tapissés respectivement par des sables fins à très fins et des sables moyens. Les levés périodiques des contours de la passe effectués jusqu'en 1993 indiquent une migration significative de l'embouchure vers l'ouest avec une vitesse de déplacement de l'ordre de 1,1m/mois. Trois chenaux bien individualisés caractérisent la zone . Ce sont au sud-ouest le chenal lagunaire, à l'Est le chenal fluvial dont la profondeur atteint 8 mètres et au Nord le chenal de Lahou Kpanda. L'analyse hydrologique montre l'importance du flot à l'embouchure Ouest tandis que les masses d'eau du jusant empruntent...

Origin and geomorphology of the wetlands of Tanzania
Provedor de dados: 20
Autores: Mwanukuzi, P. P. K.
Wetlands are dynamic landforms which vary in both time and space. Tanzania's wetlands areclassified according to the physiography and the environment in which they exist. Coastalwetlands, Rift System wetlands and the wetlands of highland drainage basins are the majorgroups. Coastal wetlands are formed by wave action and tidal influence; beaches and lagoons exist because of wave action; mudflats, marshes, mangrove swamps, estuaries and deltas aretidal in origin. Rift System wetlands occur in the rift depressions and are characterised by salt lakes, playas, swamps and short streams with inland drainage. The highlands are drained by long rivers originating in the inland catchments and ending in oceans or lake basins. On theway to their outlets, they form...

Se presentan las características hidroquímicas de las aguas de las Bahías Chile, Almirantazgo y Fildes, en las Islas del Archipiélago Shetland del Sur, en base a la distribución horizontal y vertical de los parámetros: Oxígeno disuelto, salinidad y micronutrientes inorgánicos (fosfato, nitrito, nitrato y silicato). En forma general, se observa aguas bién oxigenadas, con salinidad relativamente baja, especialmente en la capa superficial, parámetro influenciado por el aporte de aguas de deshielo de los glaciares cercanos. Igualmente alta concentración relativa de micronutrientes inorgánicos, con escasa estratificación de los mismos.

Daily growth increments (DGI) density - otolith radius relationship according to the von Bertanlanffy's growth model: application to Lutjanus sebae (Cuvier, 1828) in Seychelles. Often, age determination of fishes is conducted from several parts (scales and otoliths for teleost fishes, vertebrae, spine, opercular bones, ...) displaying seasonal marks (annuli) associated with growth checks, which can be used for the estimation of individual age. Since Panella's (1971, 1974) discovery of the daily growth increments (DGI) in the teleost otoliths, age determination with DGI method has been used more and more on larval stages of both temperate and tropical species and juvenile and adult individuals of, principally, snapper and grouper species.

During november 1992 an intense bloom of the toxic dinoflagellate Alexandrium tamarense accurred in coastal waters from Mar del Plata, Argentina. Toxicity testing of Mytilus edulis populations of the region revealed high levels of paralytic shellfish poison. In order to study the possible PSP accumulation in mackerel (Scomber japonicus), mouse bioassay(AOAC) was performed in livers from individuals captured during December 1992. Liver extracts were lethal to mice; the sumptoms observed were typical of those caused by paralytic shellfish toxins. Although PSPS concentration is below the established limit for human consumption, it suggests that mackerel can accumulate PSP toxins from its food. On the basis of stomach content analysis of sampled mackerel and...

Forestry resources in Tanzania's wetlands:concepts and potentials
Provedor de dados: 20
Autores: Nshubemuki, L.
Forestry resources include land occupied by, or proclaimed to be forest; the produce found insuch land; and human resources capable of fostering the development of such resources. The following landscape units constitute Tanzania's wetlands: estuaries, open coasts, wetlands incoastal forests, floodplains, freshwater marshes, lakes, peatlands, swamp forests, and ground water forests. Wetlands are sources of food and forest produce, contain plants potentially suitable for agro-forestry and phyto-reclamation, reduce beach erosion, and arc sources of genetic material.Most wetlands face intensive utilisation pressure which endangers their continued existence. Given the multi-utility of wetlands and their diversity in structure, it is not possible to adopt...

The present work is a study of the fishery of Panulirus gracilis (Green spiny lobster) in the ports of Chanduy, El Real and Anconcito in the north east of the Gulf of Guayaquil 58, 252 specimens caught in the 10 year period 1970 to 1979 were examined. A comparison was made of the sizes of lobsters caught with the established regulation for the explotation of the crustaceans. It was found that both the monthly and annual mean sizes were maintained above the ”minimum permitted length” which is 25 cm total length. Males predominated over females in the ratio 2:1. The percentage of males was 66,5% and of females 33,5%. During the period of the study, berried females of various sizes were frequently found, being most abundant in the months of May, June and July...

Autores: Nwadukwe, F.O.; Ayinla, O.A.
Weekly spawn and hatching rates of Clarias gariepinus and Heterbranchus longifilis were determined in earthen ponds during the rainy and dry seasons. There was a significant increase in spawn weight from the 2nd to the 7th  week after stocking C. gariepinus brood fish (p&lt;0.05).  In H. longifilis; the increase in spawn weight was significant from the 4th to the 9th weeks (P&lt;0.05). A positive correlation was found between spawn weight and female broodfish weight from the 4th to the 9th weeks for both species. The best hatching rates were obtained during the 7th week for C. gariepinus, and in the 8th week for H. longifilis.  Rainy season trials gave better results in both species than in the dry season, while only C. gariepinus produced hatchable...

The most original part consist in the application of bioenergetic and simulation models for estimating the annual food consumption by individuals and by stocks of common hake during 1970-1987, considering at the same time, the effects of commercial catches on the stockbiomasses in predator-prey relationships. From this point of view three trophic-fishery relationships are evident, namely: "Common...

From 1989 to 1992, five cruises were conducted in an area covering the English Channel, the Celtic Sea and the Gulf of Biscay. During these campaigns, suspended matter was collected by different techniques in order to analyze the spatial and vertical distribution of several particulate trace elements in relation to the global biogeochemical cycle of carbon. It appears that horizontal distribution varies strongly from one element to another and is mainly influenced either by  anthropogenic and terrigenous inputs or by scavenging processes. On the other hand, the vertical distribution seems mainly linked to the primary production. In parallel to these trace element measurements, experiments were carried out to estimate the transfer rates of these elements...

An ELISA to detect &lt;i&gt;Vibrio anguillarum&lt;/i&gt; antigen in &lt;i&gt;Artemia salina&lt;/i&gt; was developed. This assay was then used to determine the time course of antigen uptake by &lt;i&gt;Artemia&lt;/i&gt; during incubations with &lt;i&gt;Vibrio&lt;/i&gt; vaccine with a view to using &lt;i&gt;Artemia&lt;/i&gt; as a vaccine carrier for oral vaccination of fish fry. The rate of uptake of vaccine by &lt;i&gt;Artemia&lt;/i&gt; was shown to be concentration dependent.

Hatching, survival, activity and penetration efficiency of second-stage larvae of &lt;i&gt;Anguillicola crassus&lt;/i&gt; (Nematoda)
Provedor de dados: 27
Autores: Thomas, K.M.; Ollevier, F.P.
Hatching of eggs of &lt;i&gt;Anguillicola crassus&lt;/i&gt; was studied at temperatures between 5 and 30°C. Hatching occurred between 10 and 30°C and the incubation time was inversely related to temperature. Survival, spontaneous and excitatory rate of activity of 2nd-stage larvae of &lt;i&gt;A. crassus&lt;/i&gt; were also affected by temperature. The percentage of larvae eaten by &lt;i&gt;Paracyclops fimbriatus&lt;/i&gt; was not always influenced by the activity of the larvae. Penetration efficiency into the haemocoel of the intermediate host was highest for freshly hatched larvae and declined gradually with age. Completely non-active larvae were still able to penetrate, although penetration efficiency was lower.

Elemental composition of aircraft-sampled aerosols above the Southern Bight of the North Sea
Provedor de dados: 27
Autores: Rojas, C.M.; Van Grieken, R.; Maenhaut, W.
During the period from September 1988 to October 1989, 23 flights were carried out over the Dutch Continental Shelf of the North Sea and a total of 108 aerosol filter samples were collected. The samples were analyzed for Na, Mg, Al, Si, P, S, Cl, K, Ca, Ti, V, Cr, Mn, Fe, Ni, Cu, Zn, Br and Pb using both particle-induced X-ray emission (PIXE) and energy-dispersive X-ray fluorescence (EDXRF). The results from PIXE exhibited better precision and lower detection limits than those from EDXRF. Therefore the further discussion and interpretation was based on the PIXE data only. It was observed that Si, S, V, Mn, Ni, Cu and Pb were enriched with respect to the earth's crust. It was seen that winds from the sector Southeast-South contributed most significantly to...

The use of brine shrimp &lt;i&gt;Artemia&lt;/i&gt; in biological management of solar saltworks
Provedor de dados: 27
Autores: Tackaert, W.; Sorgeloos, P.
In recent years, there has been a growing awareness of the hydrobiological aspects of the solar salt production process. Saltworks are man-managed artificial ecosystems that are highly vulnerable to biological disturbances, including uncontrolled proliferation of microalgae resulting in a reduced evaporation and contamination of the salt with gypsum and insoluble organic materials.Optimal production of solar salt, both in terms of quality and quantity, requires a well-established balance between the primary and secondary producers, with brine shrimp &lt;i&gt;Artemia&lt;/i&gt; grazing on phytoplankton constituting the major interaction. In this paper, we discuss the beneficial role of &lt;i&gt;Artemia&lt;/i&gt; in balancing the hydrobiological activity of...

EDXRS study of aerosol composition variations in air masses crossing the North Sea
Provedor de dados: 27
Autores: Injuk, J.; Van Malderen, H.; Van Grieken, R.; Swietlicki, E.; Knox, J.M.; Schofield, R.
X-ray emission techniques for bulk and individual particle analysis (EDXRF, EPXMA, micro-PIXE) were combined and applied in atmospheric research on the North Sea area as part of a field-study on air-sea exchange processes of particulate matter. The atmospheric loading for a number of elements was determined by EDXRF, yielding bulk concentrations for Mg, Al, Si, S, Cl, K, Ca, Cr, Mn, FE, Ni,Cu, Zn, BR and Sr. From these EDXRF data, deposition rates were derived and, based on a classical multivariate statistical approach, different aerosol sources were identified. Complementary to this work, EPXMA combined with automated image analysis was applied to individual size-segregated aerosol particles to determine their inorganic composition, physical size and...

Eocene siliciclastic continental shelf sedimentation in the Southern Bight North Sea, Belgium
Provedor de dados: 27
Autores: Jacobs, P.; Sevens, E.
Eocene sedimentation in the Southern Bight of the intracratonic North Sea Basin is determined by its ramp margin setting. Lithofacies analysis of siliciclastic shallow marine sediments enables reconstruction of sedimentation model in relation to relative sea level changes. Two major sedimentary cycles composed of sequences of metric to decametric thickness can be discerned. The lower transgressive/regressive cycle evidences 3 sedimentary environments. Lowermost Eocene sediment units are mainly clayey, display an overall fining upward trend an are deposited on a mud shelf. A delta prograding out on the continental shelf deposits middle to upper Lower Eocene units, gradually becoming more sandy. Middle Eocene sediments are mainly sandy, contain calcarenite...

Provedor de dados: 27
Autores: Hamerlynck, O.; Cattrijsse, A.; Arellano, R.V.
In order to estimate daily ration of juvenile &lt;i&gt;Potamoschistus lozanoi&lt;/i&gt; and to evaluate the effect of tide and daylight on its feeding activity, two 24h samplings were performed, one (in 1985) with high water around midnight, the other (in 1986) with low water around midnight. Incidently, the sampling in 1985 was around neap tide and in 1986 it was around spring tide. The fish were observed to feed more intensively during the night. Daily ration in 1985 was estimated to be about 1% of body ash-free dry weight (ADW). For 1986, the estimate is about 5% of body ADW in spite of similar water temperatures at both sampling dates. It is suggested that a semilunar rhythm, either in the fish or in the invertebrate prey, is the basis of the observed...

The use of the McLaren Model for the determination of residual transport directions on the Gootebank, Southern North Sea
Provedor de dados: 27
Autores: Lanckneus, J.; De Moor, G.; Van Lancker, V.R.M.; De Schaepmeester, G.
Sixty samples were collected on the Gootebank to assess the application of the McLaren sediment transport model on a tidal sandbank environment. Residual sediment transport directions were deduced and compared with the results of a detailed bedform analysis obtained by side-scan sonar recordings. Results show that when sediments become finer and better sorted, the corresponding skewness becomes more positive which is in contradiction with the sediment transfer function of McLaren and Bowles (1985). Comparison of the directions of residual sediment transport deduced from bedform analysis and from the sediment trend analysis shows that a good similarity is reached in the adjacent swales and that an offset of 90° exists on the bank. The transversal grain-size...

This note reports on the presence of a well established population of the isopod &lt;i&gt;Synidotea laevidorsalis&lt;/i&gt; (Miers) in the Gironde estuary (southwestern France). This species is new for the European fauna. &lt;i&gt;S. laevidorsalis&lt;/i&gt; is a nonendemic cool-temperate to subtropical, shallow-water species which was probably introduced into the study area from Asia. In the salinity range of 1 to 10 g l&lt;sup&gt;-1&lt;/sup&gt; of the Gironde the species constitutes an important component of the brackish-water hyperbenthic community. The population was already present in 1975 when it was misidentified as the native species &lt;i&gt;Idotea emarginata&lt;/i&gt; (Fabricius).

Autores: Van Alsenoy, V.; Bernard, P.; Van Grieken, R.
The elemental composition of sediment and suspended matter samples from the Belgian coastal and offshore regions of the Southern Bight of the North Sea and from the Scheldt estuary has been determined using X-ray fluorescence and atomic absorption spectrometry.Special attention was given to the heavy metals of the black and grey lists. The bulk sediment and the clay/silt fraction were analyzed. The average heavy metal contents in the fraction &lt;63 µm were comparable to the levels in the suspended matter. Different normalization techniques led to the identification of two different populations of sediments. Most of the sediments were enriched in Cd, Cr, Hg, Pb and Zn but no enrichment was found for Cu and Ni. Comparing these data with older data indicates...

This paper reports on enrichment techniques oriented towards a specific DHA accumulation in the live prey &lt;i&gt;Brachionus plicatilis&lt;/i&gt; and &lt;i&gt;Artemia sp.&lt;/i&gt; The product used in these experiments (DHA7) is an experimental emulsion with a DHA/EPA ratio 6.7:1. Rotifers enriched with this pure DHA7 emulsion contained up to 69 mg/g DW DHA and a DHA/EPA ratio of 1.6. The DHA/EPA ration could be increased to a much higher level by different enrichment techniques. Dilution of the DHA7 emulsion with coconut oil prior to enrichment also had a beneficial effect on the DHA/EPA ratio of the rotifers. Using a mixture DHA7/coconut oil 3:7 the DHA/EPA ratio could be raised to 4.9. In &lt;i&gt;Artemia&lt;/i&gt; DHA levels were slightly influenced...

Autores: Merchie, G.; Lavens, P.; Nelis, H.; De Leenheer, A.P.; Sorgeloos, P.
A study was undertaken to upgrade the levels of vitamin C in &lt;i&gt;Artemia&lt;/i&gt; and &lt;i&gt;Brachionus&lt;/i&gt; through bioencapsulation and to investigate in this way the requirements for ascorbic acid (AA) during larviculture of fish and prawn. Ascorbyl palmitate (AP) was used as the vit C source because of its stable and lipophylic characteristics which allowed its incorporation in booster emulsions and its readily conversion into AA by &lt;i&gt;Brachionus&lt;/i&gt; and &lt;i&gt;Artemia&lt;/i&gt; . Under standard conditions very high levels of AA could be incorporated into the &lt;i&gt;Artemia&lt;/i&gt; nauplii: supplementation of the enrichment emulsion with 20% AP (w/w) increased the AA-content up to 2000 ppm after 24h enrichment.

Among the many techniques available at the Micro and Trace Analysis Center (MiTAC) for the observation and analysis of individual particles, electron probe X-ray microanalysis (EPXMA) in combination with multivariate classification techniques allows the most advanced characterization of individual particles in a fast and efficient way. All facilities of EPXMA were used for the source apportionment of more than 25,000 individual aerosol particles detected above the North Sea, the English Channel and the Celtic Sea. The North Sea aerosol is predominantly composed of sea salt, sulfur-rich particles, silicates and calcium sulfate particles.

An intensive approach to Atlantic halibut fry production

The larval stage is regarded to be the main bottleneck of halibut production. Halibut eggs were obtained from captive broodstock both by stripping and by natural spawning. Artificial photoperiods were used to increase the total spawning season. Yolk sac larvae are presently produced either in small stagnant units or in large flow through systems. A major consideration is to avoid stress of the larvae, caused by mechanical disturbances of the larvae and by high bacterial load or high ammonia levels in the water.The experimentation showed that halibut larvae began to ingest algae earlier than rotifers &lt;i&gt;Brachionus&lt;/i&gt; sp. Supplementation of algae to first feeding tanks resulted in enhanced survival and growth rate of the larvae. Both rotifers...

The invertebrate zooplankton fauna of the Westerschelde (Belgium and The Netherlands) was investigated during 2 yr by means of monthly samples along a salinity gradient. Copepods were usually the most abundant holoplanktonic metazoans except in the freshwater zone where Rotifera were most numerous. The combination of a classification technique and an ordination-regression technique proved to be a valuable tool for the analysis of such an extensive data set. The presence of 4 groups was established, representing spatially distinct populations but with temporally shifting boundaries. Few zooplankton species were truly estuarine in their distribution, but many were derived from nearby coastal waters. This intrusion of marine species started in spring,...

Autores: Dhont, J.; Lavens, P.; Sorgeloos, P.
The brine shrimp,&lt;i&gt;Artemia&lt;/i&gt; has played a significant role in the expansion of the commercial production of shrimp and prawn during the last decade. Being an off-the-shelf and easily usable live food,&lt;i&gt;Artemia&lt;/i&gt; is the main alternative for the natural diet of shrimp larvae. It appeared in the late 1970s that the nutritional value of &lt;i&gt;Artemia&lt;/i&gt;, especially for marine organisms, is not constant, but varies both geographically and temporally, causing unreliable outputs in marine larviculture.

This paper describes apparatus, techniques and methods used by participants in MAST G6M project 4 (Cohesive Sediments) for determining cohesive sediment properties. This comparison of methods aims to stimulate a more general discussion on standardisation of techniques which will lead to characterisation of muds in terms of physical parameters. Such characterisation would allow intercomparison of muds from different sources. Methods are given for sediment properties of grain size distribution, settling velocity and rheological parameters and for water-bed exchange properties of permeability, effective stress and critical shear stress for erosion and deposition. Accuracy and repeatability are discussed. A typical range of values is indicated for each of...

An overview of the wet deposition of micropollutants (trace metals -Cd, Cr, Cu, Pb, Hg, Zn- and organic compounds -PAHs, PCBs, pesticides) to the North Sea and adjacent areas is presented. The results of (in)direct measurements of the wet flux are compared to modeling results. Attention is given to specific problems like revolatilization, sea-spray, contamination, gas-to-particle ratios in wet deposition of Hg and the organic substances. Also, the importance of wet deposition is weighted to that of dry deposition and non-atmospheric input routes to the North Sea. It is concluded that -especially for organic micropollutants- current knowledge is insufficient to yield an accurate and detailed image of the impact and importance of wet deposition to the North...

Autores: Rojas, C.M.; Injuk, J.; Van Grieken, R.; Laane, R.W.P.M.
During the period from September 1988 to October 1989, 23 sampling flights were carried out over the Southern Bight of the North Sea. In the campaign, both bulk and size-segregated airborne particulate matter samples were collected. Dry deposition velocities for Cd, Cu, Pb and Zn have been estimated using a modified version of the two-layer of Slinn and Slinn and the particle size distribution obtained from size-fractionated samples. Results pointed out that the main difference between our results and those reported in the literature lies in the aerosol size distribution. Dry deposition rates calculated using these deposition velocities as a function of wind sector showed that continental air masses, particularly those associated with the wind sector west...

Styracothoracidae (Copepoda: Harpacticoida), a new family from the Philippine deep sea
Provedor de dados: 27
Autores: Huys, R.
A new family is proposed to accommodate Styracothorax gladiator, new genus, new species, collected from 2,050-m depth in the Philippine Sea. The Styracothoracidae is placed in the Cervinioidea on account of the fused rostrum, the setation of the antennary endopod, the reduction of the maxillulary exopod, and the uniramous fifth legs in at least the female. A suite of synapomorphies, including the subchelate maxilliped, suggests a sister-group relationship with the cave-dwelling Rotundiclipeidae. The primitive features of the Styracothoracidae and the phylogenetic relationships of the cervinioid families are discussed.

Carbon and nitrogen isotopic composition of different strains of &lt;i&gt;Artemia&lt;/i&gt; sp.
Provedor de dados: 27
Autores: Spero, H.J.; Andreasen, D.J.; Sorgeloos, P.
Stable carbon and nitrogen isotope ratios have been determined on 41 strains of &lt;i&gt;Artemia&lt;/i&gt; sp. from different geographic regions around the world. The delta &lt;sup&gt;13&lt;/sup&gt;C and delta &lt;sup&gt;15&lt;/sup&gt;N values ranged between -13.7 to -25.0 per mil and -0.7 to 21.2 per mil respectively. &lt;i&gt;Artemia&lt;/i&gt; delta &lt;sup&gt;13&lt;/sup&gt;C values from coastal environments are consistent with a marine origin for the food source. &lt;i&gt;Artemia&lt;/i&gt; from inland salt lakes have a range of carbon isotope values suggesting C&lt;sub&gt;3&lt;/sub&gt;, C&lt;sub&gt;4&lt;/sub&gt; and CAM based organic matter could form the base of the &lt;i&gt;Artemia&lt;/i&gt; food chain.

Substitute diets for live algae in the intensive rearing of bivalve mollusks: a state of the art report
Provedor de dados: 27
Autores: Coutteau, P.; Sorgeloos, P.
Hatchery rearing of bivalve mollusks depends on the production of live micro-algae, which is costly and often unpredictable, and the development of a cost-effective artificial diet would greatly reduce the operating costs and improve the efficiency of bivalve seed production. This paper reviews the literature on the use of various alternatives to on-site algal production, plus the results obtained by the authors using manipulated yeasts as algal substitutes in feeding trials with juveniles of various commercially important bivalve species, and compares this information with experience "from the field" obtained through an international survey of operators of 50 commercial and research hatcheries. Despite the extensive research efforts, it appears that...

Autores: Elskens, M.; Chou, L.; Dauby, P.; Frankignoulle, M.; Goeyens, L.; Loijens, M.; Wollast, R.
Since the role of continental shelves and coastal areas in the global biochemical carbon are nowadays a leading concern in oceanographic research programmes, this study aims to define the specific effect of nutrients on the onset and development of the phytoplankton bloom at the ocean margins. Comparison experiments of the carbon, nitrogen and phosphorus assimilation rates were carried out from 1989 to 1991 in the English Channel and the Gulf of Biscay. New production were obtained from the traditional approach using &lt;i&gt;f&lt;/i&gt;-ratio values, i.e. the ratios of directly measured nitrate to carbon uptakes and/or the ratios of nitrate to nitrate plus ammonium uptakes. Values of &lt;i&gt;f&lt;/i&gt; agree well on the shelf, slope and deep basin...

Autores: Cattrijsse, A.; Mees, J.; Hamerlynck, O.
Data are reported on the amphipods and isopods taken in a sledge-type hyperbenthos sampler in the subtidal of the Voordelta, a shallow coastal area in the Westerschelde, the last estuary of the delta area (SW Netherlands). More than 300 samples were collected between 1988 and 1991. Two salt marches in the brackish part of the estuary were sampled monthly with a flume net in 1990 and 1991.A total of 46 amphipod species (42 gammarideans, 3 caprellids and 1 hyperiid), 19 of which are new for the area were recorded. The dominant amphipod species in the Voordelta and the marine part of the Westerschelde estuary are &lt;i&gt;Atylus swammerdami&lt;/i&gt; and &lt;i&gt;Gammarus crinicornis&lt;/i&gt;.

Habitat verlies en degradatie is één van de belangrijke ecologische problemen van deze eeuw. Hoewel alle ecosystemen hieronder te lijden hebben, blijken wetlands of waterrijke gebieden, op wereldschaal vrij zeldzame gebieden, onder zeer zware antropogene druk te staan. Het is daarom ook niet te verwonderen dat deze ecosystemen sinds meerdere jaren een belangrijke prioriteit vormen voor het natuurbehoud. Binnen de wetlands vormen estuaria zeer produktieve systemen waarvan het rijke voedselaanbod wordt benut door grote aantallen steltlopers, die buiten het broedseizoen bijna volledig op dergelijke getijdengebieden zijn aangewezen.

&lt;i&gt;Mesacanthion diplechma&lt;/i&gt; (Nematoda: Thoracostomopsidae), a link to higher trophic levels?
Provedor de dados: 27
Autores: Hamerlynck, O.; Vanreusel, A.
The nematode Mesacanthion diplechma Southern is relatively rare in sediments of the Southern Bight of the North Sea and the Dutch Delta. Strangely, it is about the only free-living nematode found in the stomachs of the sand goby Pomatoschistus minutus Pallas from the same general area and even more peculiarly several hundred animals were found in sand gobies from the central part of the Oosterschelde. The large size of the nematode and its preference for the superficial sediment layers are probable causes for the first observation. For the second observation there is at present no explanation that can be substantiated. Some nematodes are known to aggregate on dead animals and possibly the Oosterschelde gobies may have been feeding on such an aggregation.

Provedor de dados: 27
Autores: Huys, R.; Conroy-Dalton, S.
A new genus and species of Cylindropsyllidae (Copepoda, Harpacticoida), collected from shallow subtidal sand in the Southern Bight of the North Sea, is described and illustrated. Willemsia calceola gen. et sp. n. exhibits a unique kind of sexual dimorphism on the male P3 not observed thus far in any other harpacticoid. It is further distinguished from all known Cylindropsyllinae by the absence of an isolated midventral copulatory pore, the fades of the P2-P3 in the female and the peculiar shape and orientation of the fifth pair of legs in both sexes. Based on the sexual dimorphism of the P2 exopod and P3 endopod, it is suggested that W. calceola shares a sistergroup relationship with Stenocaris kerguelenensis Bodiou, 1977 which is transferred to a new...

In 1988 juvenile bib (&lt;i&gt;Trisopterus luscus&lt;/i&gt;) and whiting (&lt;i&gt;Merlangius merlangus&lt;/i&gt;) were studied in a shallow coastal area by monthly sampling with fine-meshed nets. 0-group fish of both species are first caught in May. By the end of the first growth season bib reached about 150mm SL (standard length), whiting about 170mm SL. Maximal densities were recorded in June and by the end of the year most fish had left the area. The instantaneous mortality is estimated at 0.008 day&lt;sup&gt;-1&lt;/sup&gt; (0.77% day&lt;sup&gt;-1&lt;/sup&gt; for bib and 0.76% day&lt;sup&gt;-1&lt;/sup&gt; for whiting) for both species.

The size spectra and biomass of the nematode assemblages in the sediments of &lt;i&gt;Avicennia marina, Bruguiera gymnorrhiza, Ceriops tagal&lt;/i&gt; and &lt;i&gt;Sonneratia alba&lt;/i&gt; at Gazi Bay (Kenya), are described. Weighted mean length (resp. dry weight) of the nematodes varies from 0.543 to 1.367mm (resp. 0.10 to 0.19µg) and differs considerably from geometric and median values. Nematodes become longer (around &lt;i&gt;Avicennia&lt;/i&gt; and &lt;i&gt;Sonneratia&lt;/i&gt;) or remain similar in length (around &lt;i&gt;Bruguiera&lt;/i&gt; and &lt;i&gt;Ceriops&lt;/i&gt;) with increasing depth into the sediment.

Comparison of three dry deposition models applied to field measurements in the Southern Bight of the North Sea
Provedor de dados: 27
Autores: Rojas, C.M.; Van Grieken, R.; Laane, R.W.P.M.
Dry deposition velocities have been calculated using three different approaches. Turbulent wind profile theory has been used to predict the drag coefficient, wind speed and friction velocity at 10m height when the wind speed is measured at a higher altitude. The resulting parameters were introduced in a two-layer deposition model. The second approach was the well-known model of Slinn and Slinn (1980, Atmospheric Environment 14, 1013-1016), whereas the third corresponded to the model published by Williams (1982, Atmospheric Environment 16, 1933-1938). Results point to clear differences. However, in a field experiment carried out at the Southern Bight of the North Sea, all three approaches show relatively comparable results. The role played by the size...

During the ANTARKTIS VIII/5 cruise (December 1989 -March 1990), which was jointly carried out by AWI and RCMG, the seismic grid already available in the Weddell Sea could be expanded with up to 4100 km of high-resolution reflection seismic profiles. The Meso-Cenozoic seismostratigraphic model, originally defined on ODP Site 693 (Leg 113), was extended throughout the existing seismic database along the entire eastern Weddell Sea continental margin. This correlation effort provides some closer time constraints on different stratigraphic units elsewhere in the Weddell Sea, a.o. within the Crary Fan depositional system.

Geochemical characterization of recent sediments in the Baltic Sea by bulk and electron microprobe analysis
Provedor de dados: 27
Autores: Belmans, F.; Van Grieken, R.; Brügmann, L.
Nineteen samples of silty and clayey sediments of the Baltic Sea were analyzed by bulk methods (atomic absorption spectrometry and inductively coupled plasma optical emission spectrometry), as well as by electron probe X-ray microanalysis (EPXMA). Processing of the EPXMA-data resulted in nine different particle types which have been identified as different mineral species. Quartz and aluminosilicate particles are most abundant (often more than 95%), although they are not of much help for the characterization of the geochemistry of Baltic sediments. Reduction products, such as Fe-sulfides and rhodochrosite, are found in anoxic sediment environments (e.g. Gotland Deep). The oxides/hydroxides of iron and manganese are more indicative of toxic environments...

Among the live diets used in the larviculture of fish and shellfish, the brine shrimp &lt;i&gt;Artemia&lt;/i&gt; nauplii constitute the most widely used food item; i.e., over 700 metric tons of dry &lt;i&gt;Artemia&lt;/i&gt; cysts are annually marketed worldwide for on-site hatching into 0.4 mm nauplii.Although the use of &lt;i&gt;Artemia&lt;/i&gt; appears to be simple, considerable progress has been made in the past decade in improving and increasing its value as a larval diet for marine fish larvae. The improvements include: identification of the most appropriate strains and batches; new techniques for cyst disinfection; decapsulation and hatching; and enrichment and cold storage of nauplii.

Archisenia gen. nov. is proposed to accommodate the sibirica-group of the genus Danielssenia Boeck, 1872. Re-examination of Alaskan material of D. stefanssoni Willey, 1920 has shown the latter species to be a junior synonym of D. sibirica Sars, 1898, the type and only species of the new genus. Danielssenia robusta Sars, 1921 and Fladenia intermedia (Wells, 1965) are synonymous and consequently F. robusta comb. nov. becomes the type species of the genus Fladenia Gee &amp; Huys, 1990. Danielssenia similis Chislenko, 1971 is regarded as species inquirenda and the genus Danielssenia is redefined from the type species D. typica Boeck, 1872, and two other species (D. quadriseta Gee, 1988 and D. reducta Gee, 1988).

Autores: Dhert, Ph.; Bombeo, R.B.; Sorgeloos, P.
Juvenile and adult &lt;i&gt;Artemia&lt;/i&gt; produced in a semi flow-through culture system were used as food for postlarval shrimp. The growth performance of shrimp reared on such ongrown &lt;i&gt;Artemia&lt;/i&gt; live prey is identical to the growth obtained when feeding newly hatched &lt;i&gt;Artemia&lt;/i&gt; . However, a significantly better stress resistance is obtained when the postlarvae are exposed to a low salinity in a stress test. Besides nutritional and energetic advantages, the use of &lt;i&gt;Artemia&lt;/i&gt; biomass for feeding postlarval shrimp also results in improved economics as expenses for cysts and weaning diets can be reduced.

Autores: Adriaens, D.; Decleyre, D.; Verraes, W.
Like most gobies, &lt;i&gt;Pomatoschistus lozanoi&lt;/i&gt; is a benthic fish species. During locomotion the pectoral fin adduction is of great importance in generating a forward propulsion. Several specimens of &lt;i&gt;Pomatoschistus lozanoi&lt;/i&gt; were dissected, cleared with staining and sectioned with staining, in order to examine the morphology of the pectoral girdle-apparatus. In this paper a detailed description is given of the skeletal elements, the musculature and the ligaments of the pectoral girdle-apparatus. The pectoral fins of gobies seem better adapted to powerful adduction than a generalised teleost. The proximal radials form a large rigid shoulder plate with a long distal margin on which a high pectoral fin articulates. The fin muscles...

Diagnóstico da agricultura orgânica no estado do Rio de Janeiro e propostas para sua difusão.
Provedor de dados: 21
Autores: Assis, Renato Linhares de.
A agricultura organica tem sido citada recentemente por um numero cada vez maior de pessoas como uma opção viavel ao modelo agricola atual, o qual tem provocado sérios problemas ambientais e para saude humana. No entanto, pouco se tem observado como se da o processo de adocao deste sistema de producao por agricultores e consumidores para que se possa difundi-lo cada vez mais. A partir de entrevistas com produtores organicos fluminenses, procedeu-se a uma analise do processo de adocao deste tipo de agricultura e das dificuldades para sua difusao no Estado do Rio de Janeiro. Verificou-se que os agricultores entrevistados, possuidores de forte posicionamento ideologico, funcionam como importante vanguarda no processo de difusao, o qual, para ser incrementado...

Effect of three farming systems (bio-dynamic, bio-organic, conventional) on yield and quality of beetroot (Beta vulgaris L. var. esculenta L.) in a seven year crop rotation
Provedor de dados: 21
Autores: Mäder, P.; Pfiffner, L.; Niggli, U.; Balzer, U.; Balzer, F.; Plochberger, A.; Velimirov, A.; Besson, J.-M.
In a long-term field trial in Therwil, Switzerland, the bio-dynamic, bio-organic and conventional farming systems were compared (DOC trial). The present paper focuses on long-term yield development and on product quality of beetroot. Due to the favourable climate and soil, beetroot yields were generally high. The yield of beetroot in both biological systems was about 75 % that of the conventional system, but the input of nitrogen and potassium was about 60 % lower.

Boundaries between soil compartments formed by microporous hydrophobic membranes (GORE-TEX®) can be crossed by vesicular-arbuscular mycorrhizal fungi but not by ions in the soil solution
Provedor de dados: 21
Autores: Mäder, P.; Vierheilig, H.; Alt, M.; Wiemken, A.
Various container systems have been described in which soil regions available to hyphae only are separated from the mycorrhizal root region by 30–60 μm mesh screens to study nutrient exchange between plants and fungi in the mycorrhizal symbiosis. The screens designed up to now prevent penetration by roots but allow easy passage of fungal hyphae as well as diffusion or mass flow of water and nutrient solutions. We tested hydrophobic microporous polytetrafluorethylene (PTFE) membranes (GORE-TEXR) with 5 to 15 μm diameter pores in an attempt to obtain a better seal between compartments and to prevent uncontrolled nutrient transport by diffusion or mass flow. We found that these membranes completely prevented diffusion or mass flow of ions between two soil...

Influência da cobertura morta no comportamento dos herbicidas imazaquin e clomazone
Provedor de dados: 87
Autores: Rodrigues,Benedito N.
Experimentos de campo e bioensaios em casa-de-vegetação foram realizados para se estudar a influência da cobertura morta de trigo (Triticum aestivum L.) no comportamento dos herbicidas imazaquin {ácido 2-[4,5 dihidro-4-metil-4-(1-metiletil)-5-oxo-1H-imidazol-2-ilo]-3-quinolinacarboxílico} e clomazone {2-[(2-clorofenil)metil]-4,4-dimetil-3-isoxazolidinona}, aplicados em pré-emergência na cultura da soja [Glycine max (L.) Merril], no sistema de plantio direto. O clomazone mostrou evidências de ter sido interceptado pela cobertura morta. A presença da cobertura morta não influiu na retenção do imazaquin, sendo este lixiviado da palha para o solo com as chuvas que ocorreram após a aplicação.

Injúria potencial de herbicidas de solo ao girassol: II - chlorimuron-ethyl
Provedor de dados: 87
Autores: Fleck,Nilson G.; Vidal,Ribas A.
Conduziu-se um ensaio de 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 do herbicida chlorimuron-ethyl aplicado em três doses à superficie do solo (PRE) ou incorporado no mesmo (PPI), sobre a cultura de girassol. A atividade de chlorimuron-ethyl (etil 2-((((4-cloro-6-metoxipirimidina-2 il)amino)carbonil)amino)sulfonil)benzoato) não foi dependente de sua posição no solo. Chlorimuron-ethyl promoveu injúria inicial acentuada, constatando-se pouca ou nenhuma resposta ao aumento da dose para matéria seca da parte aérea do girassol, área foliar e estatura das plântulas. Contudo, avaliação de estatura das plantas, realizada...

Provedor de dados: 87
Autores: Carvalho,José Eduardo B. de; Caldas,Ranulfo C.; Cardoso,Silvana S.; Costaneto,Antônio O.
Durante 4 anos agrícolas, conduziu-se um experimento no município d Rio Real, BA, com o objetivo de determinar o período em que as plantas daninhas apresentam maior interferência na produção da cultura durante o ano, levando-se em consideração a disponibilidade de água no solo, em função do balanço hídrico climatológico que estimou sua capacidade de armazenamento em 125 mm de água. Os tratamentos constituíram um arranjo do controle do mato nas quatro épocas pré-estabelecidas. As principais plantas daninhas presentes foram a falsa-serralha (Emilia sonchifolia), capim-colchão (Digitara horizontalis), capim-favorito (Rynchelitrum roseum) e picão-preto (Bidens pilosa). Na época 1 (dezembro, janeiro e fevereiro) ocorrem pouquíssima água armazenada no solo e...

Injúria potencial de herbicidas de solo ao girassol: I - clomazone
Provedor de dados: 87
Autores: Vidal,Ribas A.; Flecks,Nilson G.
Conduziu-se um ensaio de campo na Estação Experimental Agronômica da Universidade Federal do Rio Grande do Sul, em Eldorado do Sul, RS, em 1989/90. O objetivo deste trabalho foi determinar o efeito residual potencial do herbicida clomazone, aplicado em três doses à superfície do solo (PRE) ou incorporado no mesmo (PPI), sobre a cultura de girassol. Através de ensaio complementar, realizado em casa-de-vegetação em 1990, procurou-se determinar o local de absorção de clomazone por plântulas de girassol. A localização de clomazone no solo foi muito importante na determinação de sua injúria para o girassol. A campo, clomazone promoveu injúria mais acentuada nas plântulas, quando aplicado em PRE do que em PPI. Clomazone, aparentemente, foi mais absorvido pelo...

Analyzing the Impacts of the Proposed North American Free Trade Agreement on European-North American Dairy Trade Using a Joint-Input, Multi-Product Approach
Provedor de dados: 31
Autores: Bishop,   Phillip M.; Pratt,   James E.; Novakovic,   Andrew M.
Mathematical programming models, as typically formulated for international trade applications, may contain certain implied restrictions limiting price responsiveness, intermediate product flows, and arbitrage possibilities. These restrictions are especially important in the case of dairy, and may lead to results which are technically infeasible, or if feasible, not consistent with market equilibrating behavior. The difficulties encountered when modeling dairy trade are described, and an alternative formulation of a spatial model is presented. This formulation allows joint-inputs, multi-products, intermediate markets, and pure transshipment and product substitution forms of arbitrage.

AN ANALYSIS OF ECONOMIC EFFICIENCY IN AGRICULTURE: A NONPARAMETRIC APPROACH
Provedor de dados: 31
Autores: Chavas,   Jean-Paul; Aliber,   Michael.
A nonparametric analysis of technical, allocative, scale, and scope efficiency of agricultural production is presented based on a sample of Wisconsin farmers. The results indicate the existence of important economies of scale on very small farms, and of some diseconomies of scale for the larger farms. Also, it is found that most farms exhibit substantial economies of scope, but that such economies tend to decline sharply with the size of the enterprises. Finally, the empirical evidence suggests significant linkages between the financial structure of the farms and their economic efficiency.

THE CAP REFORM AND EC-US RELATIONS: THE GATT AS A "CAP" ON THE CAP
Provedor de dados: 31
Autores: Guyomard,   Herve; Mahe,   Louis Adrien Pascal; Roe,   Terry L.; Tarditi,   Secondo.
Reform of the Common Agricultural Policy has entailed the substitution of new income support instruments for the former price based instruments, mainly in the cash crop sector.  Our first point is that the domestic political balance was unable to generate such a large change in policy design, in spite of inefficiencies and inbalances.  The pressure of the US has been a major factor in the design of the reform.  We argue that trade interests have been crucial to catalyze international collective action in order to countervail domestic pressure groups.  The pursuit of an agreement in the GATT is therefore a means to place a cap on the CAP and foster some reform and control over sectors such as sugar and dairy in other countries.  We do not foresee the...

PRICE ARBITRAGE BETWEEN QUEENSLAND CATTLE AUCTIONS
Provedor de dados: 31
Autores: Williams,   Christine H.; Bewley,   Ronald A.
In a competitive market with free information flows, spatial arbitrage will ensure that average prices at geographically separate markets will move in unison. The speed of adjustment is related to information flows between markets; if adjustment lags exist, there may be opportunities for arbitragers to gain. The transmission of price information is modelled using Johansen's procedure and the existence of long-run arbitrage opportunities is investigated. An innovation analysis is used to examine the varying responses to changes in prices at spatially separate markets.

DO CORN FARMERS HAVE TOO MUCH FAITH IN THE SUGAR PROGRAM?
Provedor de dados: 31
Autores: Rendleman,   C. Matthew; Hertel,   Thomas W.
Corn producers frequently have been told that the sugar program provides an important stimulus to corn demand through its positive influence on the high fructose corn syrup sector. In this article we qualify the extent of this support and find it to be very small- not more than 3 cents per bushel, and probably less. Previous studies have overstated this effect due a lack of attention to the interindustry linkages in the sweetener complex.

The National Dairy Heifer Evaluation Project ( NDHEP ) was conducted by the National Animal Health Monitoring System (NAHMS ) from April 1991 through July 1992. A total of 921 producers monitored calves on a daily basis from the first through the eighth week of life; results were extrapolated to the U.S. dairy population. Mortality of heifer calves was examined according to region ( west, midwest, northeast, southeast ). Mortality was highest in the western region ( 9.1 percent ) and lowest in the midwestern region ( 5.6 percent ). Calf deaths were highest in the two quarters October-December and January-March ( 8.4 percent each quarter ) and lowest in the quarter April-June ( 5.2 percent ). The overall average of stillborn calves was 1.6 percent. Calving...

THE IMPACT OF DOMESTIC AND FOREIGN MACROECONOMIC VARIABLES ON U.S. MEAT EXPORTS
Provedor de dados: 31
Autores: Liu,   Donald J.; Chung,   Pin J.; Meyers,   William H.
This paper examines the impact of domestic and foreign macroeconomic variables on U.S. meat exports, including beef, pork, turkey, and chicken, in the context of an open economy.  The results show that foreign macroeconomic variables exert more significant and persistent effects on U.S. meat exports than domestic macroeconomic variables.  The implication is that the U.S. can increase its meat exports more effectively by expending efforts on international macroeconomic policy coordination rather than on domestic sectoral policy.  The results also suggest that macroeconomic models of the agricultural sector should include foreign variables and should not be limited only to domestic ones.

Autores: Karungu,   Peter; Reed,   Michael R.; Tvedt,   Douglas D.
A capitalization approach is used to estimate econometrically the effects of exchange rate, interest rate and tax law changes on thoroughbred yearling prices.  The analysis found that exchange rate and tax law changes have significantly influenced yearling prices since the early 1980s.  Another serious price-reducing event was the 1986 tax law change.

ACREAGE RESPONSE, EXPECTED PRICE FUNCTIONS, AND ENDOGENOUS PRICE EXPECTATIONS
Provedor de dados: 31
Autores: Choi,   Jung-Sup; Helmberger,   Peter G.
Taking the price of futures as a proxy for expected price, this article treats acreage planted to soybean, the price of futures, and other variables as jointly dependent. A futures price equation is embedded in a simultaneous equations model along with the consumption demand and acreage response. The model is estimated using both ordinary and three-stage least squares. Estimated price elasticities for consumption demand, demand for stocks, and acreage response equal, respectively, -.5, -1.8, and +.2 (short run) and +.59 (long run).

MANAGING AGRICULTURAL OPERATIONS OVERSEAS: LESSONS FROM THE PAST
Provedor de dados: 31
Autores: Johnson,   Nancy L.
The prospect of trade liberalization at both the regional and global level opens up the possibility of increased agricultural investment in developing countries.  Such opportunities can be very appealing to developed-country producers who face high domestic costs, particularly for land and labor.  Further, foreign investment could be an extremely positive development in terms of using developed country technical knowledge to increase global food production.  However putting this experience into practice overseas has not always been successful in the past.  The history of expatriate investment in developing country agriculture does not offer many encouraging examples.  Often overlooked in the literature of both agricultural economics and management, private...

Autores: Byrne,   Patrick J.; Capps,   Oral, Jr.; Williams,   Gary W.
The analysis focused on economic forces influencing U.S. lamb consumption at the consumer level. The demand for lamb was shown to be inelastic. Key determinants of lamb consumption were habit persistence, seasonality, own price, and the price of pork. Income, trend and the price of beef were not statistically important factors.

ILLINOIS PRODUCE GROWERS STUDY - VIABILITY OF SOUTH WATER MARKET IN CHICAGO AS AN OUTLET FOR MARKETING PRODUCE AND ANALYSIS OF NET RETURNS RECEIVED THROUGH ALTERNATE MARKETING CHANNELS
Provedor de dados: 31
Autores: Mandal,   Sanjay; Thompson,   Sarahelen R.; Good,   Darrel L.
Most Illinois produce growers do not participate in the wholesale marketing system. Instead, most concentrate their efforts in direct marketing of their produce via pick-your-own operations, roadside stands, farmers' markets, and contracting with food processing firms. Currently only 2-3 percent of the produce arriving in Chicago is of Illinois origin. The wholesale market for produce in Chicago has traditionally been organized around the South Water Market. The small involvement of Illinois producers in the South Water Market is of concern because 1) it may be indicative of problems in the wholesale marketing system used to bring produce to regional retail and hospitality markets, and 2) because it may imply that income generating opportunities for...

ON MODELING SYSTEMS OF CROP ACREAGE DEMANDS
Provedor de dados: 31
Autores: Coyle,   Barry T.
This article presents an alternative approach to the specification of systems of crop acreage responses. Derived demands for acreages of individual crops are specified as conditional on total crop acreage, and related separability and dynamic specifications help to reduce the effects of multicollinearity in the system. A simple econometric model of crop acreage demands for Western Canada illustrates the methodology.

MEASURING PROTECTION IN AGRICULTURE: THE PRODUCER SUBSIDY EQUIVALENT REVISITED
Provedor de dados: 31
Autores: Masters,   William A.
In the 1980s, the Producer Subsidy Equivalent (PSE) became the dominant measure of protection in applied studies of international agricultural trade. This paper analyzes potential biases in the ratio form of the PSE introduced by using actual domestic prices rather than social opportunity costs in the denominator. It is shown that doing so introduces a consistent under-estimation of the effects of trade restrictions and other price-support policies, relative to deficiency payments and other income-support policies. It is found that under plausible conditions this bias leads the PSE to rank protection levels across countries or crops incorrectly. In a sample of 250 activities across 33 countries, such errors were found to occur in 5% of crop comparisons and...

EVALUATING U.S. GENERIC MILK ADVERTISING EFFECTIVENESS USING AN IMPERFECT COMPETITION MODEL
Provedor de dados: 31
Autores: Suzuki,   Nobuhiro; Kaiser,   Harry M.; Lenz,   John E.; Forker,   Olan D.
An analytical model to evaluate the effectiveness of u.s. generic milk advertising which incorporates the degree of market competition is presented. Unlike traditional perfect competition models, the imperfect competition model allows for simultaneous movement of both price and quantity with an endogenous fluid (Class I) price differential. The simulation results of the imperfect competition model are compared with the conventional exogenous fluid price differential model. It is shown that the conventional fixed fluid price differential model may under-state the effectiveness of U.s. generic milk advertising in terms of returns to producers.

IMPACTS OF CHAPTER 12 AND LENDER LIABILITY SUITS ON BANKERS' PROPENSITY TO LEND IN WESTERN ARKANSAS
Provedor de dados: 31
Autores: Dixon,   Bruce L.; Raub,   Kristin M.; Flaccus,   Janet A.
The recent availability of Chapter 12 bankruptcy and the more frequent use of lender liability suits by borrowers are factors that may be adversely affecting the supply of agricultural loans.  An experiment using hypothetical loan applications was undertaken involving 34 banks in western Arkansas.  Responses were used to estimate the impacts of these legal procedures on banks' lending behavior.  The estimated models indicate Chapter 12 is not a significant factor in the loan approval process.  Lender liability has marginal significance in lowering the probability of granting an intermediate term loan.

A GAME THEORY ANALYSIS OF MANAGEMENT STRATEGIES FOR THE SOUTHERN BLUEFIN TUNA INDUSTRY
Provedor de dados: 31
Autores: Klieve,   H. M.; MacAulay,   T. Gordon.
Game theory offers an alternative approach to standard means of resource assessment which can be of value in the definition and assessment of policy options for competing parties. Using a Nash co-operative game it has been possible in this paper to show the significance of fishing strategies for southern bluefin tuna which take into account the age distribution of the catch. Assuming Japan and Australia act according to a cooperative game then the optimal fishing strategy was found to involve Australia avoiding the fishing of the very young cohorts and Japan taking a moderate catch in subsequent older age classes but not the oldest of the age classes. Sub-optimal strategies were also presented and evaluated along with an indication of the level of biomass...

FARM VALUE OF TOPSOIL IN SPRING WHEAT PRODUCTION
Provedor de dados: 31
Autores: Williams,   Jeffery R.; Tanaka,   Donald L.; Herbel,   Kevin L.
Relationships among topsoil removal treatments and additions of nitrogen and phosphorus fertilizer in spring wheat yields are used to determine the effects on net returns and to estimate the marginal value of soil. The results indicate that risk-averse managers are not willing to make an expenditure for controlling erosion from the first 2.5 inches of soil if the erosion rate is 20 tons/acre/year or less and the planning horizon is 20 years or less. These managers would be willing to make an erosion control investment for the second 2.5 inches of soil equivalent to $4.90 to $5.20/acre from the twenty-first to forty-third year in the planning horizon.

Land Tenure and the Management of Land Resources in Trinidad and Tobago
Provedor de dados: 31
The potential of the agricultural sector in Trinidad and Tobago has not been realized in recent decades. The more productive land resources of the country are underutilized, while many of the more fragile ecosystems are in danger. This threatens to deny the country potential income from ecotourism as well as deprive future generations of a stable land, forest, and water base. The optimal use of the country's land resources requires a stable and secure tenure system defining land rights. The Government of the Republic of Trinidad and Tobago contracted the Land Tenure Center to carry out land rationalization studies, which are intended to assist in the preparation of an action plan to deal with the problems of the land tenure system. The result was the...

Since 1980, incremental state and national policy decisions concerning public higher education have had a variety of effects on students and institutions.  Although there has been very little research, most of these effects appear to be detrimental to the health of the system of public higher education and to the nation's stock of human capital.  A thorough economic analysis of the effects of policy changes on public higher education is needed to guide the system into the 21st century.

INCORPORATING THE 1990 FARM BILL INTO FARM-LEVEL DECISION MODELS: AN APPLICATION TO COTTON FARMS
Provedor de dados: 31
Autores: Duffy,   Patricia A.; Cain,   Danny L.; Young,   George J.
A five-year, 0.1, mixed integer programming model was developed to analyze the effects of 1990 Farm Bill legislation on the crop-mix decisions made on cotton farms.  Results showed that, when compared to the 1985 Farm Bill, the 1990 Farm Bill can result in higher whole-farm income despite new "triple base" provisions limiting payment acres.  The increase in income results from elimination of limited cross-compliance provisions and the change to a three-year base calculation.  The model was also used to assess the likely impact of possible changes in the current legislation.

Modelling the adoption of HYV technology in developing economies may be effectively prosecuted at the microlevel in a non-separable, decision-theoretic system. The degree of adoption of high-yielding varieties of rice can be incorporated into the household decision framework and account can be taken of imperfections in labour and commodity markets. Despite the gap between theory and practice, an embryonic empirical model is implemented using survey data from Orissa, India to appraise the effectiveness of a range of agricultural policies on farm-family welfare, farm output, marketed surplus of food and rural employment.

An Analysis of Alternatives to the Dairy Price Support Program
Provedor de dados: 31
Autores: Kaiser,   Harry M.
The U.S. dairy industry has operated under a price support program since 1949. Between 1949 and 1980, the dairy price support program generally operated without incurring large government costs and was an effective price stabilizer. However, since 1980, the dairy industry has experienced chronic excess production relative to consumption and consequently government purchases under the price support program have been excessively large (particularly in the mid-1980s). The tremendous increase in government costs of the dairy price support program and a growing dissatisfaction with the program by farmers has prompted proposals to modify or replace this program. This paper examines the potential market impacts of five different dairy policy scenarios. The five...

MORALE AND FACULTY DEVELOPMENT IN AGRICULTURAL ECONOMICS
Provedor de dados: 31
Autores: Purcell,   Wayne D.
Morale and faculty development are closely related. The agricultural economics profession must decide what it is about. There is room to practice the principle of comparative advantage and allow a degree of specialization in teaching, extension, and research. To continue in the role of an applied discipline, there must also be an opportunity for the young professional to establish rapport with, and understanding of, the private sector and the policy-making arena. If that is to happen, there must be encouragement in the institutional setting and by faculty colleagues who respect the importance of investment in building rapport and in establishing credibility. If that environment is present, morale should be good and faculty development will occur.

WHEAT CLEANING DECISIONS AT COUNTRY ELEVATORS
Provedor de dados: 31
Autores: Johnson,   D. Demcey; Wilson,   William W.
This article presents a mathematical programming model of wheat cleaning and blending decisions at a country elevator. Simulations are performed to illustrate the sensitivity of cleaning to selected variables, including the value of screenings, transportation costs, and market discounts for excess dockage.  In addition, the model is used to assess the impact of including dockage in the grade standards for wheat.

A CROSS-SECTION ANALYSIS OF INTRA-INDUSTRY TRADE IN THE U.S. PROCESSED FOOD AND BEVERAGE SECTORS
Provedor de dados: 31
Autores: Hartman,   Darcy A.; Henderson,   Dennis R.; Sheldon,   Ian M.
This paper analyzes the determinants of variation across industries in levels of intra-industry trade (IIT) for a sample of 36 U.S. processed food and beverage industries in 1987, previous studies of intra-industry trade having focused on industry characteristics in the manufacturing sectors. The determinants predicted by IIT theory are measures of product differentiation, economies of scale, and imperfect competition; the results of this analysis indicate that IIT variation across the food and beverage industries is positively related to product differentiation, U.S. total trade, similarity of tariff barriers among trade partners, and economies of scope, but negatively related to industry concentration.

Economic Significance of Peanut Production and Income to Georgia Farms, Rural Communities
Provedor de dados: 31
Autores: Shurley,   W. Donald.
Peanuts accounted for 34 percent of Georgia’s crop income and 13 percent of the State’s total farm income in 1992. The total economic impact of peanut production to the Georgia economy is $1.16 billion annually. Per acre, peanuts provide 2.8 times the debt serving capacity of cotton, 6.1 times that of soybeans and 16.4 times that of corn. The peanut price support and quota program adds economic stability to local economies. The value of peanut quota adds an estimated $48 million to Georgia farmland values, which provides collateral for agricultural lenders. A reduction in peanut prices would adversely reduce farm income and cash-flow, quota values, land values, and the real estate tax base of rural communities. Adverse changes may not alter the comparative...

Experience with World Bank Funded Rural Development
Provedor de dados: 31
Autores: Donaldson,   Graham.
Rural development projects, designed to reach large numbers of families in villages throughout the world, were a major element in World Bank strategy in the 1970s and 1980s. Evaluation of nearly 400 completed projects shows two out of three have been satisfactory. This paper reviews and extracts lessons from evaluation of both satisfactory and unsatisfactory projects. Based on these findings it postulates a three part model of successful rural development initiatives based on incentive, production and institutional components.

The Economics of New Technology Adaptation and Adoption
Provedor de dados: 31
Autores: Anderson,   Jock R.
Adaptation is a critical aspect of applied agricultural research but is one that should be better understood. Accordingly, its dimensions are explored here through analogies with the adaptive behaviour of a person seeking a change in employment. A similar process is then used to illustrate the sequential phases of the adoption of a new technique by  farmer-in this case through analogy with the purchase of an automobile. Although adaptation and adoption are quite different phases of the implementation of new technology, their economics are closely interrelated, since an ex ante investigation of the economics of adoption is a necessary consideration in the ex ante appraisal of a process of adaptive research.

QUANTIFYING THE EFFECTS OF NEW PRODUCT DEVELOPMENT: THE CASE OF LOW-FAT GROUND BEEF
Provedor de dados: 31
Autores: Brester,   Gary W.; Lhermite,   Pascale; Goodwin,   Barry K.; Hunt,   Melvin C.
Low-fat ground beef (LFGB) is a new product designed to be as palatable as beef products that contain significantly higher levels of fat. A hedonic model shows that each unitary increase in the leanness of ground beef products carries a price premium of $.0206/lb. If LFGB garners a 10% share of the ground beef market, the retail price of all ground beef products will increase by $.01/lb. and consumption will increase by 39.75 million lbs. The price of commercial cows will increase by $.56/cwt. Price quantity, and welfare measures are magnified as the market share captured by LFGB increases.

THE IMPACTS OF LESSER DEVELOPED COUNTRIES ON SOUTHERN REGION AGRICULTURAL EXPORTS
Provedor de dados: 31
Autores: Marchant,   Mary A.; Ruppel,   Fred J.
Lesser developed countries (LDCs) serve as both customers and competitors for agricultural commodities produced in the Southern region of the United States.  This paper focuses on the impacts of LDCs on exports of the major agricultural commodities produced in the South (cotton, rice, tobacco, poultry, and, to a lesser extent, citrus and peanuts).  First the importance of LDCs as export markets for Southern commodities is explored.  Then the role LDCs play as producers and exporters of these commodities is considered.  Finally, these separate roles are combined into an index of LDC competitiveness with Southern agricultural commodities.  Data analysis shows that Southern agricultural interests truly are divided over the role LDCs play in Southern...

This study aimed to investigate the strategic assumptions and practices in World Bank project appraisal programs. Semistructured interviews of senior World Bank field officers in Addis Ababa and Nirobi and extensive review of World Bank appraisal directives and related documents provided the data for the study. The purpose was to see the correspondence between Bank project appraisal methods, assumptions, and criteria and the iterative/participatory development model.   The findings suggest that despite the Bank's awareness of the inherent value of the iterative/participatory development model and expressed interest in changing the direction of the Bank's development practices towards it, the project approach with appraisal emphasis on monetary and...

Many countries of the Western Hemisphere in recent years have shown interest in participating in preferential trading arrangements (PTA) in anticipation of expanding exports. Results in this paper show that export expansion depends upon the type of agreement that is formed and who else is participating. Trade of two agricultural commodities are examined; wheat, and fruit and vegetable juices. Five PTAs are examined, each including the United States and one or more Western Hemisphere countries.

PRIVATISING THE PRODUCTION OF KNOWLEDGE: PROMISE AND PITFALLS FOR AGRICULTURAL RESEARCH AND EXTENSION
Provedor de dados: 31
Autores: Lindner,   Robert K.
In the absence of some form of government intervention, knowledge is a classic public good which will be under-produced because of lack of price excludability. Government intervention may take the form of establishing intellectual property rights, or other means of shielding knowledge-based innovations from imitation or copying. Such intervention offers the prospect of 'privatising' the production of knowledge in the sense that a certain level of private knowledge production may become profitable if producers can appropriate at least part of the benefits of R&amp;D.  However, publicly funded R&amp;D or extension still can 'crowd out' private knowledge production by charging lower prices. The principal finding of this study is that such 'crowding out'...

ANALYSIS OF GENERI&lt;; DAIRY ADVERTISING SCENARIOS ON RETAIL, WHOLESALE, AND FARM MILK MARKETS
Provedor de dados: 31
Autores: Kaiser,   Harry M.; Forker,   Olan D.
An econometric model of the United States dairy industry is used to simulate the economic impact of alternative strategies in the generic advertising of dairy products. Advertising programs for fluid milk, cheese, and butter are considered. The historic quarterly advertising expenditure levels experienced during the period October 1984 through December 1990 are used as a basis of comparison. A national model enables the analyst to simultaneously estimate the impact of changes in advertising expenditures on price and volume of sales at retail, wholesale, and farm levels of trade. The impact on government purchases can also be estimated. The simulations indicate that the largest impact of decreases or increases in advertising expenditures is on price. A 50...

The Impact of Investments in Maize Research and Dissemination in Zambia Part I: Main Report
Provedor de dados: 31
Autores: Howard,   Julie A.; Chitala,   George M.; Kalonge,   Sylvester M.
Michigan State University (MSU) is currently assessing the impact of agricultural research on various commodities in seven African countries: Cameroon (maize, cowpea, sorghum), Kenya (maize, wheat), Malawi (maize), Mali (maize), Niger (sorghum, cowpea, millet), Uganda (oilseeds), and Zambia (maize). These countries were selected because they represent a variety of agro-ecological regions, and because their research systems have received significant levels of funding from USAID. The country studies undertaken by MSU are part of a series of research works recently commissioned to help USAID and the U.S. Congress analyze the effectiveness of aid given to strengthen national agricultural research systems in Africa.

Factor Input Demand Subject to Economic and Environmental Risk: The Case of Nitrogen Fertilizer in Corn Production
Provedor de dados: 31
Autores: Carriker,   Gordon L.
Nitrogen (N) fertilizer demand in relation to economic and environmental risks associated with N-fertilizer management are examined. Both nominal and environmental damage-adjusted net returns distributions are evaluated using stochastic dominance analysis. Results suggest that, in the absence of environmental risk, N demand becomes more elastic as farmers become more risk averse. When environmental risk is introduced to the decision-making process, N demand becomes even more elastic.

Economic Criteria for Settling Federalism Disputes with an Application to Food Safety Regulation
Provedor de dados: 31
Autores: Caswell,   Julie A.; Kleinschmit,   Jaana K.
Federal ism disputes arising from state regulations, particularly those pursuing health, safety, and environmental goals, are a common feature of the U.S . political system. Discussion of bases for settling such disputes often focuses on the in- and out-state incidence of benefits and costs but incidence is a complex concept that has not been systematically analyzed. We discuss five factors important to evaluating incidence and present spillover criteria for judging disputes based on them. When applied to a Massachusetts regulation of daminozide residues in heat-processed apple products, the criteria reach different conclusions on its appropriateness, although the main criteria suggest it should be invalidated by the courts or preempted by federal law.

Autores: Richardson,   James W.; Anderson,   David P.; Peel,   Derrell S.; Phillips,   Mike.
A whole-farm simulation model is used to analyze the impacts of PST adoption on representative farms in Missouri and Indiana. Farmers who do not adopt experience lower average annual net cash farm incomes than adopters. Lower feed prices and/or an average PST/feed response decrease the incentive adopt. Payment of a 5 percent carcass merit premium (CMP) and/or higher grain prices greatly increase the economic incentive to adopt.

Autores: Runge,   C. Ford.
This study has attempted to respond to four key questions surrounding  the debate over NAFTA and its impact on Minnesota.  The first question concerns its employment impacts:  Will NAFTA cost jobs in Minnesota? The answer appears to be no.  The magnitude of employment impacts from NAFTA is small but positive.  Many of the gains will be in Minnesota      agriculture with some widely distributed benefits in manufacturing and  no effect on services employment.  If the effect of NAFTA is to lead Mexico into a period of higher sustained growth, the dynamic process of income generation that results could boost demand for trade with Minnesota to levels higher than predicted, with accompanying increases in employment.  But taking the most conservative predictions,...

Autores: Karlson,   Nicholas; Anderson,   Brad; Dahl,   Reynold P.
This study analyzes the role of futures markets in corn marketing decisions.  Besides price discovery and price-risk management, hedging in the futures market facilitates a return to corn storage.  First, the seasonality in corn marketings and prices is examined.  Second, the seasonality of the difference between cash and futures prices, the basis, is analyzed.  Understanding the basis is important because it is a useful guide for decisions on corn storage and sale.  Finally, several corn marketing strategies are developed and analyzed.  Cash corn prices at Clarkfield, Minnesota, and futures prices on the Chicago Board of Trade are used in the analysis.

Provedor de dados: 31
Autores: Unnevehr,   Laurian J.; Bard,   Sharon K.
A nationwide retail survey is used to estimate hedonic prices of fat characteristics in beef table cuts.  Results show that consumers consistently place a negative value on external fat for all table cuts and on seam fat in chuck and round cuts, but do not consistently value intramuscular fat.  These consumer preferences are not transmitted to cattle feeders through price signals, even though the current beef grading system can distinguish carcasses with undesirable fat characteristics.

Expectations of Cattle Feeding Investors in Feeder Cattle Placements
Provedor de dados: 31
Autores: Kastens,   Terry L.; Schroeder,   Ted C.
Cattle feeders appear irrational when they place cattle on feed when projected profits are 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 information than the live cattle futures market price when making placement decisions. This paper examines feeder cattle placement determinants and compares performance of expected hedgeable profits with past actual profits in explaining feeder cattle' placements. Past actual profits are found to be more important placement determinants than expected profits based upon the live cattle futures market, even though hedgeable profits provide...

Provedor de dados: 31
Autores: Siegel,   Paul B.; Leuthold,   Frank O.
Retirement/recreation communities (RRCs) have been promoted as a way for some rural regions to develop their economies.  RRCs can have substantial economic impacts (changes in employment and income) and fiscal impacts (changes in local government revenues and costs) on rural communities.  Because the magnitude and direction of these impacts are site-specific, assessments of RRCs as a rural development strategy should consider both the economic and fiscal impacts for a given region.  This paper presents a case study of the economic and fiscal impacts of Tellico Village on Loudon County, Tennessee.

Segmenting the Milk Market into bST-Produced and Non-bST-Produced Milk
Provedor de dados: 31
Autores: Tauer,   Loren W.
This paper discusses the value to milk producers and consumers of segmenting the milk market into bST-produced milk and non-bST-produced milk markets, versus losing milk consumption from consumers who will not consume bST-produced milk. Results indicate that both bST-using producers and non-bST-using producers benefit from a segmented market when compared to losing milk markets. Even if market loss does not occur, segmenting the market benefits producers not able to effectively use b~T and may even benefit bST users if the use of bST significantly shifts the supply curve for milk. Non-bST consuming consumers benefit from the availability of non-bST milk, and consumers who are indifferent to the use of bST pay about the same price in a segmented market.

With the rapid increase in consumption of some livestock products in Indonesia, expansion of domestic production of these commodities may enhance smallholders' incomes, increase rural employment and add to the country's trade balance.  Policy analysis matrices (PAMs) were constructed to estimate divergences between private and social costs and returns in poultry and pig production in selected regions of Indonesia.  In each case, producers' use of capital was subsidized but feed input private costs exceeded social values, and output prices received by producers fell short of values based on world prices.  Production of all products as import substitutes was socially profitable, but in many instances private returns to farmers were negative.  Product price...

Organic farming in Australia: An economist's perspective
Provedor de dados: 31
Autores: Marshall,   Graham R.
Organic agriculture has emerged as an important contributor of ideas in the continuing Australian search for sustainable farming systems. Recognising this, choices arise over the need for government intervention to foster the development of organic approaches to agriculture. Even when the choice is to not intervene directly, an understanding of factors behind how voluntary conversion to this way of farming would help governments, farmer organisations and agribusiness to meet the demands of converting farmers for knowledge, inputs and services. The aim in this paper is to assist informed resolution of these questions.

Farmer Productivity at Various Ages
Provedor de dados: 31
Autores: Tauer,   Loren W.
The productivity of farmers at six different age cohorts was computed by estimating production functions using 1987 census data. The results suggest that farmers of different ages operate with slightly different technologies and use various inputs at different efficiencies. Compared with previous 1978 estimates, the productivity of middleaged farmers appears to be even greater than the productivity of younger and older farmers. The average age of U.S. farmers exceeds the age of highest productivity from these estimates.

A SURVEY OF ECONOMIC MODELS OF THE DAIRY INDUSTRY
Provedor de dados: 31
Autores: Kaiser,   Harry M.; Blayney,   Donald P.
The purpose of this report is to catalog, describe, and provide information concerning existing models of the dairy sector. Many types of dairy models are listed in this report. The models vary by geographic aggregation (e.g., farm, state, regional, national, and international levels), time dimension (e.g., comparative static, annual, quarterly, monthly, weekly, daily specifications), principal application (e.g., Federal Milk Marketing Order, dairy price support program, operations analysis, etc.), computer requirements (mainframe vs. micro-computer, DOS vs. Apple), ease of use, i.e., "user friendliness," and other dimensions. The report should be useful for individuals interested in the dairy industry, public policy, or quantitative methods.

Micro-level Studies and Policy Analysis: Experiences from Tonga and South Kalimantan
Provedor de dados: 31
Autores: Delforce,   Julie C.; Potter,   Lesley M.
Policy-oriented studies at the household and village level are undertaken by researchers from a range of disciplines. In this paper, we focus on two such studies, one conducted in Tonga by agricultural economists, the other in Indonesia by a geographer. While there are differences in disciplinary approach, some fundamental requirements emerge for the successful integration of micro-level research into the policy making process.

THE IMPACT OF REDUCED AGRICULTURAL CHEMICAL USE ON FOOD: A REVIEW OF THE LITERATURE FOR THE UNITED STATES
Provedor de dados: 31
Autores: Senauer,   Benjamin.
Concerns about food safety and environmental quality have increased in recent years.  Consumers are particularly concerned about the health risks posed by pesticide residues in food and the environmental impact of agricultural chemicals.  These concerns have stimulated a considerable amount of recent research to assess the effects of reduced agricultural chemical use.  This paper focuses on the research in the United States which has examined the impact of reduced agricultural chemical use on food, including food prices, consumer acceptance, food quality, and food demand and consumption. This review is divided into three major sections.  The first gives an overview of consumer concerns and behavior, using the results of the annual Food Marketing Institute...

ECONOMIC DEVELOPMENT IN A FLEDGLING DEMOCRACY: THE POTENTIAL OF THE POLISH AGRICULTURAL EXTENSION SYSTEM
Provedor de dados: 31
Autores: Doye,   Damona G.
Agricultural economists who serve as educators in emerging democracies have the opportunity to contribute to economic development by building human capital.  A channel for educators to share lessons learned in these countries could benefit individuals preparing for assignments in foreign countries.  Understanding the cultural and social differences in decision-making systems is critical to successful educational program development and implementation.  Individuals in the emerging democracies often need training in management and market economics to apply at institutional as well as personal levels.  Similar training for recipients of economic development funds could result in more effective application of funds.

Estimating Regional Demand for Feed Barley: A Linear-Programming Approach
Provedor de dados: 31
Autores: Johnson,   D. Demcey; Varghese,   Beena.
The regional demand for feed grains is not directly observable. This study uses a programming model to derive a demand schedule for feed barley. The model is applied to a major barley producing region (North Dakota and Minnesota) and an important feed deficit region (California). Direct and cross-price elasticities are evaluated, and sensitivity analysis shows the potential impact of improved barley varieties on regional demand.

GRANTSMANSHIP AND CONSULTING POLICY
Provedor de dados: 31
Autores: Knutson,   Ronald D.
Market forces, when viewed from the perspective of faculty salaries alone, clearly indicate that the highest and best use of a faculty member's time and expertise is no longer university employment. As a result, many productive faculty members are becoming increasingly dissatisfied, and many top domestic undergraduate students are eliminating academia as an employment alternative. This trend operates to the long-run detriment of the land grant university system. In part, these forces are a direct result of outdated and/or unimaginative administrative policies, inadequate reward systems, and the inability of the profession to demonstrate its productivity in terms that society understands and appreciates. Implications are drawn for land grant consulting and...

OUTPUT CHANGE IN U.S. AGRICULTURE: AN INPUT-OUTPUT ANALYSIS
Provedor de dados: 31
Autores: Holland,   David W.; Martin,   R.P.
This paper analyzes output changes in the U.S. agricultural economy from 1972 to 1977 using a 477-sector input-output framework. The empirical model is based on benchmark input-output data from the U.S. Bureau of Economic analysis for 1972 and 1977. Output changes were decomposed into components attributable to technical change, domestic final demand change, export demand change and import substitution. A major advantage of the decomposition is its ability to identify the output change in a given sector due to general equilibrium effects in all sectors.

Does Muscle Matter? An Economic Evaluation of Live Cattle Characteristics
Provedor de dados: 31
Autores: Williams,   Christine H.; Rolfe,   John; Longworth,   John W.
The Queensland Livestock Market Reporting Service (QLMRS) was established in 1980 by the livestock and Meat Authority of Queensland. Weekly reports on the major live cattle auctions in Queensland indicate the prices of different types of cattle, categorised by their age, sex, weight, fat score and type of feed. Previous research has suggested that differences in these characteristics account for only some of the price variation observed at cattle auctions. This paper investigates other characteristics not included in the QLMRS market reports which may be important in determining the price of cattle. Data on the standard QLMRS characteristics and on other potentially important characteristics have been collected by the authors for a large number of lots of...

Opaluch and Just reported the top 20 departments in pages per faculty of articles in the American Journal of Agricultural Economics for the five year period 1968-1972.  To determine how much has changed and how much has not during the intervening two decades, the analysis was repeated for the five year period 1988-1992.  Some things seem not to change.  University of California, Berkeley, remains at the pinnacle twenty years later.  And 13 of the top 20 departments two decades ago, remain there during the 1988-1992 period.  But seven did change, and the most notable aspect is that the number of Northeast departments in the top 20 rose from two to five.

The purpose of this consumer survey was to learn more about consumer preferences for meat characteristics.  Value added meat processors faced with the problem of trying to identify market niches wanted to know what types of consumers had similar preferences and what their specific preferences and concerns are.  In addition, we wanted to learn more about attitudes that are believed to be changing due to new information about the relationship between diet and long term health, lifestyles that demand more convenient foods and less home cooking, the environmental impacts of cattle production, and social issues such as animal rights.

A Review of the Taxation of Property: Local Government Rates in Victoria 1
Provedor de dados: 31
Autores: Johnson,   David T.
The paper reviews the taxation of property in Victoria and in particular the method of raising revenue for local government from rural landowners. A major contradiction between the apparent philosophical basis and its application is identified. A modification to the existing method of calculation is suggested based on the use value of rural land. The advantages and disadvantages of the use value modification are discussed and compared to the system of property taxes presently used. The use method system implies a changed incidence of tax on the three categories of taxpayer; farm, residential and commercial. The split between these categories for aggregations of local governments under the proposed situation and in the present situation is compared.

Formula Price Contracts as an Alternative to Forward Integration by Farmer Cooperatives
Provedor de dados: 31
Autores: Royer,   Jeffrey S.; Bhuyan,   Sanjib.
Firms may seek contractual alternatives to vertical integration in order to achieve transactional economies or adjust for market imperfections. Blair and Kaserman have shown that under fixed-proportions production technology. Firms within bilateral and successive monopoly market structures can use formula price contracts to achieve results economically equivalent to integration. This paper examines whether formula price contracts are a viable alternative to forward integration for farmer cooperatives. Analysis of a three-stage vertical market structure indicates that the conditions under which a cooperative assembler can use a formula price contract are more restrictive than those for an investor-owned firm.

The acceptance of the NAFTA and GATT trade agreements will impact the U.S. peanut industry. This paper examines trade distorting policies and evaluates the effects of trade liberalization on peanut producers, shellers, manufactures, and U.S. consumers of peanut products. Decreasing marketing quotas and support prices are expected to reduce gross income peanut farmers, revenues to local governments, and tax bases in rural communities. Reduced peanut production would impact buyers/shellers through greater price variability and risk, changes in marketing methods and contractual relationships, and increased emphasis on buying high quality peanuts. Manufactures will have additional sources for peanut supplies. Consumers’ savings from decreases in raw peanuts...

Autores: Cummings,   Ronald G.
This paper addresses the critical importance for Georgia of a comprehensive state-wide water plan, as well as statutory and regulatory structures that make manifest the state’s commitment to the efficient use of its water resources. To establish this importance, the author draws form experiences in Western States. Aside from benefits attributable to improved in-state allocations of water, the benefits of comprehensive state water plans are shown to relate to criteria now being used by the Supreme Court in adjudications involving equitable apportionment and/or commerce clause limitations on a state’s right to protect intrastate groundwater resources.

This paper reviews theories that identify motives for mergers, reviews recent empirical research, specifies a model that incorporates alternative motives, and tests the model with data from food manufacturing mergers between 1979 and 1986. Results suggest that capital markets are not efficient, and that mergers are not to redress agency problems. Acquirers paid higher premiums for target firms that have recently had low profitability, and paid higher premiums when the stock market was low. The model explains at best 30 percent of the variation in premiums, suggesting that major explanations for mergers remain as yet unidentified.

Recognizing that the green revolution has resulted in considerable success in production of rice and wheat in many Asian countries, which are now self-sufficient or surpluses in these cereals, IFPRI believes that further growth in agriculture will rely on the productivity of these countries to diversify their agricultural production, while improving productivity in cereals through management and human capital-intensive increase in yield levels. Indonesia is an important example of a country where policy successes in rice production combined with other domestic and world developments in the economic environment of agriculture encouraged policymakers to consider agricultural diversification policies. Key developments leading to an increased interest in...

Discovering Production and Supply Relationships: Present Status and Future Opportunities
Provedor de dados: 31
Autores: Just,   Richard E.
In this paper the current state of supply modelling in agriculture is reviewed. It is argued that (I) the stock of knowledge of elasticities is depreciating, (2) historical estimates are misleading because many phenomena are confounded in few parameters, (3) available data are not being efficiently exploited, and (4) a proliferation of hypotheses is leading to an inability to discriminate in an appropriately comprehensive context. The latter problem is leading to an inability to do forward-looking analyses. Several suggestions are made for dealing with these problems that involve some relaxation of the standard of objectivity which in reality is unattainable in many kinds of practical applied work.

Autores: Tauer,   Loren W.
Short-run and long-run technical and allocative efficiencies were computed for 395 New York dairy farms using data envelopment or nonparametric procedures on 1990 Dairy Farm Business Summary data.  The farms were, on average, more allocatively efficient in the short run than in the long run, but were more technically efficient in the long run than in the short run.  Stanchion barns were as efficient as milking parlors, and milking more than two times per day did not increase efficiency.

Agricultural Cooperatives and Market Performance in Food Manufacturing
Provedor de dados: 31
Autores: Rogers,   Richard T.; Petraglia,   Lisa M.
Support for the cooperative yardstick hypothesis was found using a standard structure-performance model that was extended to include a cooperative market share variable and was estimated with a large cross-section of food manufacturing markets. Market concentration and advertising intensity were positively related to price-cost margins. In addition, the aggregate market share of the one hundred largest agricultural marketing cooperatives was inversely related to price-cost margins. The magnitude of the effect was largest in the more concentrated markets. This suggests that. where cooperatives have vertically extended themselves into food processing. more competitive outcomes are found even in highly concentrated markets.

Supply functions, elasticity estimates, and nonjointness test results consistently indicated that few commodities compete economically in the production of six major Texas vegetables (cabbage, cantaloupes, carrots, onions, potatoes, and watermelons). Significant bias effects caused by government-supported commodities, fixed inputs, and technological change were observed and measured. Nonnested test results for the hypothesis of sequential decision making by vegetable producers were inconclusive, but they gave greater likelihood support to sequential than to contemporaneous decision making.

THE DEMAND FOR MEAT PRODUCTS IN THE UNITED STATES: AN EMPIRICAL ANALYSIS
Provedor de dados: 31
Autores: Olowolayemo,   Surajudeen O.; Martin,   Neil R., Jr.; Raymond,   Jennie E.
Given the importance of meat consumption, and the proportion of consumers' income spent on meat, this study estimates the demand for eight meat categories using two different functional forms. An inverse almost ideal demand system (IAIDS), and linear double-log price dependent demand models are specified. In most cases, flexibilities obtained from both methods are comparable and show that the demand for meat products is price inflexible. In addition, there are regional as well as seasonal variations in the demand for meat products.

Price Transmission Processes: A Study of Price Lags and Asymmetric Price Response Behavior for New York Red Delicious and McIntosh Apples
Provedor de dados: 31
Autores: Hansmire,   Michelle R.; Willett,   Lois Schertz.
An economic model was developed to gain an understanding of price flows in the markets for New York Red Delicious and New York McIntosh apples. Price transmission processes of two apple products, fresh apples and apple juice, are analyzed and compared. Specific emphasis is placed on evaluating price lags and price asymmetry, two factors which complicate the flow of prices between market levels. Results indicate that retail prices of fresh New York Red Delicious apples and fresh New York McIntosh apples respond more fully to wholesale price increases than wholesale price decreases. Results suggest that wholesale prices of fresh New York Red Delicious and fresh New York McIntosh apples are not determined by shipping point price increases and decreases....

Autores: Boadu,   Frederick O.; Thompson,   Marla R.
This paper presents an empirical analysis of the strategic forces shaping U.S.-Mexico trade relationships and the possibilities of extending the trade agreement to the rest of the Americas. The paper concludes that constituency interests, party loyalty, the proportion of a state's population of Hispanic origin, and the influence of textile-related employment in the state were significant explanatory factors in the Congressional Fast Track vote that occurred in May of 1991.

MICRO-LEVEL SMALL RUMINANT TRANSACTION ANALYSIS AND LIVESTOCK POLICY IN SENEGAL
Provedor de dados: 31
Autores: Ndiaye,   Ousmane.
This study uses one year (1989-90) of households survey data covering all livestock transactions and input expenditures to examine the equity impacts of the Senegalese livestock policy and the factors affecting purchases and sales of small ruminants in three study zones of the Senegalese Peanut Basin. It also explores the potential for market development through more production and sales of small ruminants.  The study found that a price depressing policy on small ruminants hurts richer households more than poorer households and that the two income groups of households have the same strategy of purchase and sale of small ruminants. The major cause of small ruminant income disparities are the relatively low productivity of the poorer households. The study...

A Note on Dumping, Interest Groups and the Public Policy Process
Provedor de dados: 31
Autores: Ahmadi-Esfahani,   Fredoun Z.; Jensen,   Paul H.
As a signatory of the General Agreement on Tariffs and Trade (GATT), Australia is permitted to impose duties on goods that have been imported below 'normal value' and have caused or threatened to cause 'material injury' to the domestic industry producing 'like goods'. There has been a recent push from various industries to increase protection for producers who have been injured by such practices. The Government is concerned, however, that harsher anti-dumping regulations will damage its position in the Uruguay Round of the GATT negotiations. As a result, a Senate Inquiry was established in 1990 to review Australia's anti-dumping legislation. The objective of this paper is to examine the effectiveness of the public policy process in addressing this issue....

Wheat Cleaning and its Effect on U.S. Wheat Exports
Provedor de dados: 31
Autores: Haley,   Stephen L.; Leetmaa,   Susan E.; Webb,   Alan J.
This analysis shows that there could be net gains to the U.S. wheat industry if all U.S. export wheat were to be cleaned to a dockage level between 0.35 to 0.40 percent. These results are based on survey results of major importers of U.S. wheat, and a model of world wheat trade. Larger benefits to the U.S. wheat industry would be possible from cleaning only wheat destined to countries that demand higher quality U.S. wheat. However, these gains in export revenue from selling cleaner wheat could be offset if other exporters, especially Canada, responded in ways that would maintain their market share.

The economic feasibility of fertilizing irrigated grain sorghum with compos ted manure is evaluated using net return budgeting and production function analysis. Although the use of compost is technically feasible, the economic analysis indicates that compost does not comprise a large percentage of the nitrogen source in the profit-maximizing combination with commercial fertilizer.

On the creation and destruction of public goods : the matter of sequencing
Provedor de dados: 31
Autores: Carson,   Richard T.; Flores,   Nicholas; Hanemann,   W. Michael.
We consider sequences where a subset of public goods are systematically being created or destroyed. For the case of strict Hicksian substitutes between all pairs of this subset of public goods, we show that willingness to pay for an increase in a particular public good is strictly decreasing the farther out in a sequence it is valued. For the destruction of public goods the reverse is true for willingness to accept compensation. Thus, sequencing has opposite implications for the assessment of the benefits of providing public goods and for the assessment of the damages from destroying them.

Origins of a Current Conflict? An Examination of Stock-Nonstock Cooperative Law
Provedor de dados: 31
Autores: Suhler,   Diane Rizzuto; Cook,   Michael L.
The earliest state cooperative laws in the United States were stock laws modeled upon the Rochdale experience and were adaptations of basic corporate laws of incorporation to the cooperative form of organization. They emphasized stock as the basis of membership and the distribution of profits to members in proportion to patronage. After 1911, the dominant form of cooperative law became the nonstock law. which emphasized service at cost and the personal. fraternal nature of membership in a cooperative. Since 1925. both forms of cooperative law have coexisted. The different emphasis placed on capital stock. profit. and membership in a cooperative by the two different legal structures may be one contributing factor to current dilemmas cooperative leaders face...

TESTING DYNAMIC SPECIFICATIONS FOR IMPORT DEMAND MODELS: THE CASE OF COTTON
Provedor de dados: 31
Autores: Arnade,   Carlos Anthony; Pick,   Daniel H.; Vasavada,   Utpal.
Error correction models impose few prior restrictions on dynamic model specification and allow the data to determine model structure. Despite this obvious advantage, few applications have adopted the error correction model to explain trade flows. An error correction model of cotton import demand is estimated for France, Japan, and Hong Kong. A variety of tests are applied to determine the dynamic structure of the model. We find the most general models are those that best fit the data for cotton import demand. Long-run elasticities from these general models are significantly different than elasticities derived from a comparable static model.

The Symposium on the Impact of Technology on Agricultural Transformation in Sub-Saharan Africa funded by AID/AFR/ARTS and AID/RD/EID under the Michigan State University Food Security Cooperative Agreements, was held in Washington, D.C., Oct. 14-16, 1992. A primary purpose of the symposium was to present evidence which would either confirm or contradict the perception that the accomplishments of TDT were insufficient to justify continued funding. A secondary objective was to consider the adequacy of available analytical tools for impact assessment. The rate of return (ROR) is the most commonly used valuative measure of investments in technology development and transfer. Examined as a group, the estimated RORs support the proposition that African...

FUNCTIONAL FORM AND U.S. AGRICULTURAL PRODUCTION ELASTICITIES
Provedor de dados: 31
Autores: Shumway,   C. Richard; Lim,   Hongil.
Because so much agricultural policy analysis utilizes estimates of supply and demand elasticities, it is crucial to obtain the most reliable estimates possible.  Where reliability cannot be adequately assessed, the sensitivity of elasticities to equally plausible a priori specifications should at least be ascertained.  In this article, the sensitivity of U.S. output supply and input demand elasticities to choice of functional form.  Considerable sensitivity is found to choice of functional form.  Although most frequently used, the translog is generally the outlier and is the least preferred among the alternatives.

IMPACTS OF PST ON OPTIMAL PRODUCTION AND MARKETING DECISIONS OF A GROW-FINISH HOG FARM OPERATION
Provedor de dados: 31
Autores: Govindasamy,   Ramu; Liu,   Donald J.; Kliebenstein,   James B.
This paper examines the impact of PST on the optimal production/marketing decisions of a grow-finish hog farm operation.  The analysis evaluates PST from three angles: the feed efficiency effect, the leaner meat price effect, and the aggregate-supply-induced price effect.  When limited to the feed efficiency effect only, the primary response to the new technology is to increase the animal turnover rate of the operation.  When the leaner meat price effect is also included, marketing weight increases while turnover rate remains relatively unchanged.  Additionally, if the increased aggregate supply depressed the market price by more than 10%, the benefits from improved feed efficiency and learner meat will be completely dissipated.  Aggregate price...

Welfare Effects of and Supply Responses to Recent Australian Agricultural Policy Changes
Provedor de dados: 31
Autores: Fraser,   Rob W.
This paper examines the joint impact of wheat market deregulation and removal of the wool Reserve Price Scheme on Australian wheatbelt farmers using a simple model of land allocation between the two products and empirical details of the impact of the two policy changes on farmers' uncertain economic environment. It is shown that key parameters are wool micronage, wheat yield variability and the presence or not of a wool price ceiling due to stockpile disposal. Consequently, important regional differences in welfare impacts and supply responses may exist and these may be of significance to the mechanics of stockpile disposal.

Autores: Hardaker,   J. Brian; Jarrett,   Frank G.
This paper is an introduction to the Development Studies Conference and an overview of the four main topics that were the focus of conference discussion. A survey of the evolution of development thought serves to introduce the presentation of nine hypotheses. The latter provide a framework for comment upon the four conference themes: household and village economy; the economics of institutional change; the economics of new technology adaptation and adoption; and overall planning and the economics of human resource and infrastructure development. Not unexpectedly, the chief conclusion is that there is no magic formula for development.

Revenue instability induced by conservation rate structures : an empirical investigation of coping strategies
Provedor de dados: 31
Autores: Chesnutt,   Thomas; Bamezai,   Anil; Hanemann,   W. Michael.
Water suppliers have been adopting new rate structures to promote conservation. The shift away from rates based on historical average cost toward rates based on marginal cost has been motivated by the desire to send consumers the "right" price signal about the need to conserve drinking water. The shift toward conservation rate structures, though perhaps providing better incentives to use scarce water resources wisely, has predictable effects-it changes who pays what and it increases the variability of future revenue streams to the water agency. Though the definition of the "correct" rate structure can rightfully vary in different communities-depending on the marginal cost of new supplies or avoided demand and on the community's understanding of equity-the...

ESTIMATED COSTS AND RETURNS FOR CATFISH FARMS WITH RECIRCULATING PONDS ALONG THE UPPER TEXAS COAST
Provedor de dados: 31
Autores: Lambregts,   Johannes Adrianus; Griffin,   Wade L.; Lacewell,   Ronald D.; Davis,   James T.; Clary,   Gregory M.
Cost, returns, and economies of scale for small, medium and large catfish farms with recirculating ponds are presented for the upper Texas coast. Internal rates of return are 0.150, 0.183 and 0.219, respectively. Total investment is higher than farms with static ponds but investment per unit production capacity is 7 percent to 16 percent lower. Average total cost per pound is between $0.565 and $0.541, (11 percent –20 percent lower than farms using current technology). These results have implications for regional comparative advantage of catfish production as well as incentive for adoption of new technology in conventional ponds.

THE RELATION BETWEEN FARM PRODUCTION RISK AND OFF-FARM INCOME
Provedor de dados: 31
Autores: Kyle,   Steven C.
This paper presents a model of the farm labor allocation decision based on risk and return characteristics of different activities.  It is shown that off-farm employment can play an important role in the diversification of farm family income, implying that portfolio models of risk and return to farm activities should take into account the possibility of off-farm employment.  A model of the labor allocation decision based on the risk and return characteristics of each activity is developed and tested using a state level cross section of the United States over the post-war period, and performs well in explaining variation in reliance on off-farm income.

This study compared and analyzed actual 1989 production costs for representative regional feedlots in the U.S. The results show that grain-surplus regions have lower total costs and poorer feeding efficiencies. The analysis suggests that Iowa has a comparative advantage in producing heavily marbled beef required by the Japanese market. Southwestern states have an advantage in producing leaner beef and stand to benefit if U.S. consumers develop a taste for Select-quality beef.

The strategic effects of subsidies on output and subsidies on investment differ substantially in dynamic models where a government's commitment ability is limited. Output subsidies remain effective even as the period of commitment vanishes, but investment subsidies may become completely ineffective. This difference has been obscured because most existing models of strategic trade policy are static.

MELDING PRIVATE AND PUBLIC INTERESTS IN WATER RIGHTS MARKETS
Provedor de dados: 31
Autores: Lynne,   Gary D.; Saarinen,   Phyllis.
The debate over privatizing and water markets has moved back and forth for decades between the "I" and the "We" perspectives. Rather than either/or, a balanced "I&amp;We" view of water institutions is needed. West is meeting east in water law. Public interest needs must be satisfied in appropriate decision forums, but marketing may prove a social improvement when used as a supplement. Balancing an "I&amp;We" institution involves establishing an acceptable or tolerable level of interference through judicious mixing of state, common and private property regimes. Third-party effects are eliminated as mutual gain arises in a variety of decision forums.

IMPACT OF CHANGING CONSUMER PREFERENCES ON WILLINGNESS-TO-PAY FOR BEEF STEAKS IN ALTERNATIVE RETAIL PACKAGING
Provedor de dados: 31
Autores: Schmitz,   John D.; Menkhaus,   Dale J.; Whipple,   Glen D.; Hoffman,   Elizabeth; Field,   Ray A.
The purpose of this study was to identify how consumer perceptions of selected attributes of beef steaks, individual consumer demographics and perceived changes in purchases of substitute meats affect willingness-to-pay for beef rib-eye steaks in the traditional overwrapped styrofoam tray and vacuum skin packages. A laboratory auction was used to obtain willingness-to-pay data.   The results suggest that health related factors, particularly the concern regarding cholesterol, reduced the willingness-to-pay for beef rib-eye steaks, regardless of package type. For the vacuum skin package to be successful, information about the package is necessary, along with providing a consistent and quality product, particularly with respect to trim.

Many florist crop producers have reported difficulty with attracting qualified employees to positions within their businesses. The purpose of this study was to define the difficulties florist crop producers face in attracting qualified workers. Managers of 72 florist crop production firms in Michigan, New York, Ohio, and Pennsylvania participated in a telephone survey designed to gather information on recruitment and selection issues for florist crop producers. The survey results revealed that recruitment practices were not used as frequently as they could be. It also appeared that managers were doing a better job with the selection process than they were with the recruitment process. In addition, compensation appeared to be closely linked to the ability...

Autores: Misra,   Sukant K.; Carley,   Dale H.; Fletcher,   Stanley M.
Survey data of 2,538 dairy farmers located in 12 southern states were used to analyze the factors influencing farmers' choice of milk handlers.  Results from a qualitative response model indicate that a combination of price and non-price factors contribute to dairy farmers' attitudes toward their milk handlers.  Specifically, the decision to change milk handlers was significantly influenced by prices paid and deductions charged.  However, non-price factors including field services, friendly personnel, and loyalty to a handler contributed to the longer term affiliation of dairy farmers with their milk handlers.

Autores: Chi,   R.; Lesser,   William H.
This study attempts to reconcile divergent results between two previous studies of CRJprice affects for supermarkets. A more complete data set from Kaufman and Handy is used in an earlier model by Marion et al. to determine if the differences are attributable to (1) model specifications, (2) interim structural change or (3) role of leading firm compared to all firms. The first two comparisons were indeterminate but the third provides some support for the CRJprice hypothesis compared to the size economy/service explanations. While not conclusive, these results argue for caution in rejecting SMSA supermarket concentration as an influence over prices.

Household Goals and Technology Adoption of Smallholders in Eastern Kenya
Provedor de dados: 31
Autores: Parton,   Kevin A.
The farm-household system of smallholders in semi-arid eastern Kenya is described. This is followed by a review of the extent of adoption of a set of new practices. A lexicographic utility framework is then developed to analyse the interaction between household goals and technology adoption. The results highlight the importance of closely considering goals of individual farmers when designing technologies and disseminating information on new practices.

Agriculture in the Uruguay Round: Sanitary and Phytosanitary Measures
Provedor de dados: 31
Autores: Petrey,   L.A.; Johnson,   R.W.M.
In this paper the sanitary measures for the meat trade in Pacific Rim countries are assessed from the perspective of the current GATT negotiations on sanitary and phytosanitary (SPS) measures. These negotiations include harmonisation of standards, greater transparency of domestic technical regulations, better risk assessment, promoting area freedom and improved dispute settlement procedures. It is concluded that greater coordination of SPS measures can overcome the potential misuse of some domestic policy sanitary instruments that impede international agricultural trade.

EXPIRING MINNESOTA CRP CONTRACTS: 1996-98; STATE AND COUNTY SUMMARIES
Provedor de dados: 31
Autores: Taff,   Steven J.
Nearly two million acres of Minnesota farmland have been idled under federal Conservation Reserve Program (CRP) contracts.  Starting in 1996, these 27,000 contracts will begin to expire.  The contracts summarized in this report, those which expire between 1996 and 1998, account for nearly four-fifths of the total state enrollment (Tables 1 and 2, Map 1).  This report is largely descriptive: analysis and interpretation of the data presented here are pretty much left to the reader.  The first portion of the report provides state-wide CRP summaries.  The same information at the county level is presented in Tables 9-15.

A set of ordinary and inverse demand systems for U.S. quarterly meat consumption is estimated for use to measure the effects of U.S. meat trade on consumers' welfare.  The approach is useful to incorporate all direct- and cross-commodity effects into price forecasting and the Hicksian compensating variation measurement.

COMMODITY POLICY, PRICE INCENTIVES, AND THE GROWTH IN PER-ACRE YIELDS
Provedor de dados: 31
Autores: Foster,   William E.; Babcock,   Bruce A.
We estimate the influence of policy-induced price changes and of technology supply on North Carolina flue-cured tobacco yields.  The decline in land rent and effective output price that accompanied a 1965 policy change from acreage allotments to poundage quotas caused a 12 percent decrease in yields.  Farmer yields were more responsive to yield-increasing technologies under acreage allotments than under poundage quotas.  Annual yield growth was 0.5 percent under poundage quotas and 4.32 percent under acreage allotments.  The growth rate decline is attributable to changes in relative prices and to a slowdown in the supply of available technologies.

THE IMPACT OF POLLUTION CONTROLS ON LIVESTOCK-CROP PRODUCERS
Provedor de dados: 31
Autores: Schnitkey,   Gary D.; Miranda,   Mario J.
A discrete-time, continuous-space model of a livestock- crop producer is used to examine the long-run effects of phosphorus runoff controls on optimal livestock production and manure application practices. Quantity restrictions and taxes on phosphorus application are shown to reduce livestock supply and impose greater costs on livestock-crop producers than on crop-only producers. Restrictions on manure application, without accompanying restrictions on commercial fertilizer application, will have only a limited effect on phosphorus runoff levels.

EFFICIENCY ANALYSIS OF DEVELOPING COUNTRY AGRICULTURE: A REVIEW OF THE FRONTIER FUNCTION LITERATURE
Provedor de dados: 31
Autores: Bravo-Ureta,   Boris E.; Pinheiro,   Antonio E.
This article reviews and critiques the frontier literature dealing with farm level efficiency in developing countries.  A total of 30 studies from 14 different countries are examined.  The country that has received most attention is India, while rice has been the most studied agricultural product.  The average technical efficiency (TE) index from all the studies reviewed is 72%.  The few studies reporting allocative and economic efficiency show an average of 68% and 43%, respectively.  These results suggest that there is considerable room to increase agricultural output without additional inputs and given existing technology.  Several of the studies reviewed have sought to explain farm level variation in TE.  The variables most frequently used for this...

On-farm Economics of Laser Landforming for Rice Farmers
Provedor de dados: 31
Autores: Marshall,   Graham R.; Jones,   Randall E.
The whole farm financial effects of laser land forming were analysed using a two stage modelling procedure. In the first stage, linear programming models of representative Murrumbidgee Irrigation Area (MIA) rice farms were used to predict the profit-maximising activity mixes with and without successive increments of land forming. In the second stage, the profit-maximising activity mixes with and without an increment became inputs into a spreadsheet model designed to undertake discounted cash flow analysis of investment in the increment. The transition over time of yields to the achievable levels for land formed layouts was accounted for in the spreadsheet model, as were the effects of taxation (including taxation concessions for land forming) and access to...

Mechanisms of Socio-economic Change in Rural Areas: The Case of Education and Health in Thailand
Provedor de dados: 31
Autores: Khoman,   Sirilaksana.
An emphasis on the public provision of health and education in Thailand assisted both sectors to make a substantial contribution to the consistently high growth rates achieved during the 1980s. However, a review of development goals is opportune. Three types of reform are recommended: (a) redirection of expenditure towards activities in which government participation is most critical; (b) increased reliance on user and other benefit-related charges to finance such spending; and (c) decentralisation of some public responsibilities to those in closer touch with local needs and conditions.

POLICY IMPLICATIONS OF TEXTILE TRADE MANAGEMENT AND THE U.S. COTTON INDUSTRY
Provedor de dados: 31
Autores: Shui,   Shangnan; Wohlgenant,   Michael K.; Beghin,   John C.
This study investigates the effects on the U.S. cotton industry of textile trade liberalization using a multi-market equilibrium displacement model. The simulation results suggest that textile trade liberalization would induce small changes in the total demand for U.S. cotton but would affect considerable y U.S. cotton demand structure, making U. S, cotton growers more dependent on world markets. The welfare analyses reveal that textile trade liberalization would result in a small welfare loss for U, S. cotton producers. As expected, textile trade liberalization also would lead to considerable substitution of imports for domestic production and substantial declines in prices of all textile products.

Autores: Caputo,   Michael R.; Lynch,   Lori.
In the spirit of Leamer'’s commitment to sensitivity analysis, we employ Farrell'’s nonparametric efficiency methodology and compare our results with those of Sexton, Wilson, and Wann.  Testing the implicit assumption of technical efficiency in the methodology employed by Sexton, Wilson, and Wann, we find that the lack of technical efficiency is the cotton gins'’ main cause of overall inefficiency.  We extend the nonparametric methodology by subjecting the shadow prices of technical efficiency to nonparametric statistical tests to draw stronger conclusions.  In addition, the nonparametric methodology permits us to make gin-specific recommendations to improve the performance of the gins.

ECONOMIC REFORMS IN POLAND: IMPLICATIONS FOR AGRICULTURE

Throughout the world, agriculture has become integrated into the economy at large.  Therefore, it is not possible to analyze the process of economic and political transformation of agriculture without reference to the general thrust and speed of reform (Pasour, 1992).  In this paper, we will argue that Poland, like other countries in Central and Eastern Europe, faces a dilemma of economic and political reform.  Further, we will discuss some of the central variables which tend to constrain the process of economic transition and recovery.                Following we will first discuss some of the central effects of partial and stepwise economic reform.  Second, we will analyze the pros and cons of economic shock therapy, i.e., of a rapid switch to a market...

This research explores the factors that influence the commitment of members to their cooperative organization. Previous empirical and theoretical research is reviewed. The cooperative members' decisions regarding patronage are then described in terms of a random utility model. Logit analysis, with data from member surveys of a large grain marketing cooperative. indicates that the factors that influence member patronage are: the ability to share in profits through dividends. The ability to purchase chemicals and fertilizers at the grain elevator, and the percentage of the total farm income obtained from grain operations. There is some evidence that farmers' patronage is positively associated with competitive grain pricing and negatively associated with the...

ROYALTY COLLECTION FOR PATENTED LIVESTOCK
Provedor de dados: 31
Autores: Lesser,   William H.
Allowing animal patents provides potential benefits and costs for livestock producers. Costs, considered here, are royalty payments and collection mechanisms, made more complex by the unknown future distribution of multiple patented traits in the herd. This article evaluates three proposed collection systems, Qualified Sales, registration and pooled royalties. The first two are imposed only on breeding stock and at first sale, creating a cash flow and risk factor for producers. The third collects payments from all animals at point of slaughter, based on traits in a sample. It favors producers at the cost of delayed payments to the patent holders. The eventual system used will depend on the cost and speed of testing for patented traits.

The objectives of this study were to: (a) quantify differences in liquidity costs between Kansas City and Chicago wheat futures contracts, and (b) identify the factors which influence liquidity in these two markets. Regression results suggest that there are significant differences in liquidity costs between Chicago and Kansas City which are in part due to the lower trading volume at Kansas City. However, there appears to be a significantly higher cost of doing business at Kansas City which is independent of trading volume. The implications of these findings to traders is that transacting is more expensive in Kansas City than in Chicago.

PHASING IN AND PHASING OUT PROTECTIONISM WITH COSTLY ADJUSTMENTS OF LABOUR
Provedor de dados: 31
Autores: Karp,   Larry S.; Paul,   Thierry.
We study the dynamics of optimal trade policy in a model with costly inter-sectoral adjustment of labour, where migrants pay less than the marginal social cost of migration. If workers have rational expectations, a future tariff has an announcement effect on the current migration decision. If the government is able to commit itself to future policy, the optimal trajectory involves phasing in and then phasing out protection of the dying sector. This contrasts with recommendations of gradual liberalization. Without the ability to make commitments, the equilibrium policy begins with and maintains free trade.

Concerns about the recent trends away from the consumption of red meat have led to tests for structural change in demand. These tests have typically treated the individual meats as homogeneous commodities. This article uses disaggregated data to test for structural change in the demand for differentiated meat products in Sydney over the seasons from winter 1987 to autumn 1991 using a revealed preference approach. The results fail to provide any evidence of structural change.

AGRICULTURE IN A WORLD OF TRADING BLOCS
Provedor de dados: 31
Autores: Josling,   Timothy E.
The recent trend towards the negotiation of free trade areas has potentially important implications for agriculture. Agricultural trade will increasingly be influenced by the treatment of agriculture within free-trade areas and other regional trade associations. Such blocs will have to deal internally with many of the same issues as face the GATT. This will tend to reinforce the move to less trade-disruptive domestic policies. Moreover, independent trade policies become difficult to maintain in a trade bloc, even if there is no common external tariff. This could lead to harmonisation of external policies. As a consequence, the inclusion of agriculture in free-trade areas could be an important part of overall trade liberalisation in years to come.

THE DYNAMIC EFFECTS OF AGRICULTURAL SUBSIDIES IN THE UNITED STATES
Provedor de dados: 31
Autores: de Gorter,   Harry; Fisher,   Eric O'N.
This article analyzes the dynamics effects of the farm subsidies in the United States. The subsidies a farmer receives are based upon historical plantings, also called based acreage. It is sometimes optimal for a farmer temporarily not to participate in a program in order to increase future subsidies. The farmer’'s optimal policy is the solution to a deterministic dynamic program. Farmers with low base acreage opt out of these programs, whereas those with high base acreage participate in them. The article examines aggregate data involving corn, cotton, rice, and wheat during 1987. It shows that these programs increase the output of each of these crops and represent an annual deadweight loss of more than $2 billion.

Recent Developments in Commonwealth Drought Policy
Provedor de dados: 31
Autores: Simmons,   Phil.
Some key elements in drought relief policy are outlined and the major themes in associated lobbying are discussed. Recent policy changes announced in 1992 are described in detail against the background of the Report of the Drought Policy Review Task Force (1990). Indifference curve analysis is used to compare recent developments with the preceding policies and the targeting problems associated with both policy regimes are discussed. It is found that the new drought relief policy is unsatisfactory in a number of ways. Discussion of the welfare implications of recent changes in drought policy is then provided and conclusions are finally drawn.

STRUCTURAL CHANGE IN HIGHER EDUCATION: IMPLICATIONS FOR AGRICULTURAL ECONOMICS EXTENSION; OR DOES DIFFEDENCE, DECADENCE AND DISSONANCE MAKE A DIFFERENCE?
Provedor de dados: 31
Autores: McDowell,   George R.
Discussion of changes taking place in American agriculture followed by a review of the traditional model of extension suggests there is dissonance between what is needed to inform contemporary agriculture and what extension actually does.  The paper further suggests that difficulty in packaging the newly needed information in ways that achieve the institutional maintenance objectives of extension explain a part of the system's decadence and reluctance to charge.  Since the intellectual problems of market failure, even political market failure, are within the domain of economists, diffidence by agricultural economists to those issues within the Land-Grant system can make a difference.

Sources and Effects of Instability in the World Rice Market
Provedor de dados: 31
Autores: Jayne,   Thomas S.
This report reassesses the causal link between domestic agricultural policies and world price instability, using the case of the rice market. Specifically, the report develops a framework for analyzing the effects of domestic policies on international price stability, identifies the conditions required for government policies to destabilize world markets and econometrically examines whether these conditions apply to the trade behavior of seven major rice trading countries over the period 1960-87. This is done by comparing the estimated transmission and absorption effects with those implied under free trade, by incorporating several behavioral restrictions drawn from standard trade theory. Sensitivity analysis is then used to discern how robust the results...

Human Resources Development: A Paradigm Shift?
Provedor de dados: 31
Autores: Corner,   Lorraine.
A paradigm shift is taking place in contemporary understanding of the role of human resources in development. Support for the supply-sided human capital model rests on the proposition, not yet established empirically, that it leads to more rapid rates of development than alternative approaches. The human resources development strategy stresses that human resources are both producers and the intended beneficiaries of development. It thus focuses on the achievement of human development directly, as well as indirectly through investment in human capital, and emphasises the role of rewarded economic activity and demand in successful implementation of human resources development. Important policy implications of the new HRD-based paradigm are discussed.

THE EFFECTS OF SECTORAL AND ECONOMY-WIDE POLICIES ON TOBACCO PRODUCTION IN THE DOMINICAN REPUBLIC
Provedor de dados: 31
Autores: Pena,   Pedro Pablo; Norton,   George W.
This study analyses the effects of specific agricultural and exchange rate policies on tobacco production in the Dominican Republic.  Direct protection resulting from output and input subsidies and taxes was positive on average from 1966 to 1988, but total protection was negative when exchange rate policies are considered.  Tobacco policies were quite volatile and resulted in increasing production in the 1970s but decreasing production in the 1980s.  Overall, tobacco production was 4.8 percent less than it would have been had there been no policy interventions.  Several reasons are provided for the policies.

ENVIRONMENT, INCOME, AND DEVELOPMENT IN SOUTHERN AFRICA
Provedor de dados: 31
Autores: Chapman,   Duane.
It is widely believed that rural forest and agricultural resources in Southern Africa are overused, in the sense that both biomass and harvest levels are significantly below levels of maximum sustainable yield.  However, economic theory suggests that high interest and time preference rates cause the economic optimum to coincide with generally-observed patterns.  In addition, low income may be the driving factor behind high interest and time preference rates. In macro-economic terms, Southern Africa may be experiencing a productivity crisis.  This leads to a downward shift in the labor demand curve, and an equilibrium result with undesirably low wage rates, high unit labor costs, and high and growing unemployment. In this context, the imposition of...

CHANGING AGRICULTURAL PRIVATE PROPERTY RIGHTS
Provedor de dados: 31
Autores: Bontekoe,   P.A.
Private ownership of property is a fundamental right in our democracy. Historically, land ownership and the virtually unrestricted right to use one's property, played a key role in the development and growth of this country. But private property rights are being challenged, redefined, and reallocated, resulting in new restrictions and changes in agricultural landowners' rights to use their land.  Increased awareness and concern about health and environment are causing a change in public attitudes toward agriculture. In the name of environmental protection, new restrictions are being placed on private property rights, causing uncertainties and altering the economic options available regarding the use of land for agricultural production.  This paper deals...

Empirical studies of firm diversification suggest the existence of a positive relationship between the relatedness of diversification and firm performance. Using evidence from the food manufacturing sector, we find that this relationship is weak at best and that market share appears to be a more powerful predictor of firm performance.

THE IMPACT OF SALES CHANGES ON AGRIBUSINESS PAYROLLS
Provedor de dados: 31
Autores: Gunter,   Lewell F.; Wise,   James O.
Agribusiness firms face substantial market risk associated with variations in farm production, output and input prices, exchange rates, and other factors.  Some of the risk faced by agribusiness is passed through to the employees of the firm and to the communities where the firms are located, as employment levels are changed in response to these variations.  An econometric analysis of the transmission of sales changes into payroll changes was performed for a sample of Georgia agribusiness firms.  Transmission elasticities were found to be affected by firm type, size, age, and by the degree of use part-time employees.

MEASURING FOOD SAFETY PREFERENCES: IDENTIFYING CONSUMER SEGMENTS
Provedor de dados: 31
Autores: Baker,   Gregory A.; Crosbie,   Peter J.
Conjoint analysis was used to estimate individual preference functions for food safety attributes.  Consumer segments were constructed by using cluster analysis to form groups which were homogeneous with respect to preferences regarding food safety.  Although substantial differences existed among the three distinct groups, consumers in all segments were willing to pay a moderate amount to ensure that apples met established safety standards.  However, a policy which restricts pesticide use would likely result in substantial consumer dissatisfaction, unless it could be achieved with little impact on price or quality.

Whither European Community Common Agricultural Policy, MacSharried, or Dunkeled in the GATT?
Provedor de dados: 31
Autores: Roningen,   Vernon O.
The Uruguay Round of trade negotiations in the General Agreement on Tariffs and Trade (GATT) has been deadlocked over disagreement between the European Community (EC) and other GATT members about policy reform in agriculture. Last July, Mr. MacSharry, the EC Agriculture Commissioner, proposed an internal reform of the EC Common Agricultural Policy (CAP). Meanwhile, Mr. Dunkel of the GATT Secretariat has proposed a compromise GATT agreement that would reduce support to agriculture in the EC and other member countries. This paper summarizes these two proposals for agriculture and compares the effect of their implementation by the EC. The two proposals are then contrasted from an EC policy management viewpoint.

MULTIDIMENSIONAL EVALUATION OF FLEXIBLE FUNCTIONAL FORMS FOR PRODUCTION ANALYSIS
Provedor de dados: 31
Autores: Ornelas,   Fermin S.; Shumway,   C. Richard.
Several common flexible functional forms are evaluated for Texas agricultural production utilizing three procedures. Nested hypothesis tests indicate that the normalized quadratic is the marginally-preferred functional form followed by the generalized Leontief. Predictive accuracy results are ambiguous between the generalized Leontief and the normalized quadratic. Statistical performance favors the normalized quadratic. These two functional forms consistently dominate the translog.

FACTORS AFFECTING THE ADOPTION OF SUSTAINABLE AGRICULTURAL PRACTICES
Provedor de dados: 31
Autores: D'Souza,   Gerard E.; Cyphers,   Douglas; Phipps,   Tim T.
The extent to which individual factors influence the adoption of sustainable agricultural practices is estimated using a logit model and data from a 1990 survey of West Virginia producers.  The results are, as expected, different than those for conventional agricultural technologies.  For example, the effects of human capital characteristics are significant, while those for structural and institutional characteristics are not.  However, the likelihood of adoption of sustainable agricultural practices is affected most by the environmental characteristic of whether or not the producer is aware that ground water contamination exists on his farm.  This creates an important "awareness effect" upon which policies to promote sustainable agriculture adoption can...

This paper discussed food quality issues associated with both food safety and food nutritional content.  Policy approaches to satisfying consumer demands for safe, nutritious food are described from administrative as well as economic perspectives.  Current priority issues include instituting better ways of reducing risks from microbial pathogens, from agricultural chemical residues, and – on the nutritional front – enhancing the nutritional profile of consumers' diets.  Nutrition labeling changes have been achieved.  Thus, dietary change must be attained primarily through effective means of enhancing nutritional knowledge, changing attitudes and, ultimately, behavior.

THE IMPACT OF PARCEL CHRACTERISTICS ON THE COST OF DEVELOPMENT RIGHTS TO FARMLAND
Provedor de dados: 31
Autores: Wichelns,   Dennis; Kline,   Jeffrey D.
This paper examines the economic impact of selected farmland characteristics on the appraised value of development rights.  Price elasticities are estimated for the size and location of farmland parcels, the amount of road frontage, the existence of panoramic views, and the distance to urban centers.  Estimated elasticities suggest that parcel characteristics have a substantial impact on the cost of preserving farmland.  For example, the per-acre cost of development rights is estimated to be 53 percent higher on farmland parcels that have a panoramic view of water than on parcels that have no water view.  Similarly, the per-acre cost of development rights on a typical 25-acre farm is estimated to be 90 percent higher than on a typical 150-acre farm....

THE EFFECTS OF MULTIPLE COMPONENT PRICING ON PRODUCERS AND HANDLERS IN THE FEDERAL ORDER NO. 4 MARKETING AREA
Provedor de dados: 31
Autores: Meek,   Kimberly R.
The Federal Milk Marketing Order Program was established in the Agricultural Marketing Agreement Act of 1937 to address the specific marketing problems associated with milk marketing. A supply and demand problem is created due to the daily production process of milk as well as its perishability. Fluid milk cannot be stored for long periods of time, therefore, a continual surplus must be produced in order to assure an adequate supply of fluid milk to meet the day-to-day needs of the consumers.  In order to accomplish this goal, milk orders were created, the scope and terms of which are spelled out in the Agricultural Marketing Agreement Act (7 CFR 1000-1199). The general provisions included in all orders are a "classified pricing plan, a system of minimum...

African capacity building was first identified as a major development problem during the transition to independence in the 1950s. After billions of dollars of investment in education over the past three decades, capacity building has been identified as one of Africa's most serious development problem of the 1990s. This paper analyzes African capacity building experiences over the last four decades. It focuses on the treatment of African capacity building by colonial powers, African governments, donors, and international agencies during the transition to independence in the 1950s and the post independence period since 1960. Nigeria and Kenya are used as case studies to highlight some of the key issues and draw some lessons for South Africa.   Capacity...

EFFECTS OF NON-PRICE EXPORT PROMOTION: SOME EVIDENCE FOR COTTON
Provedor de dados: 31
Autores: Solomon,   H.; Kinnucan,   Henry W.
An Annington-type trade model is estimated to determine the effects of government-subsidized export promotion on the demand for U.S. cotton in the Pacific Rim. Results show a significant relationship between promotion expenditures and U.S. market share in four of the six countries examined. One of the two countries exhibiting a non-significant effect had very low promotion expenditures, suggesting that a minimal level of funding may be necessary to achieve a market response. The hypothesis that export promotion has a carryover period lasting beyond one year in general is supported by the data. The question of the economic impacts of export promotion on domestic producers and taxpayers must await additional research.

Provedor de dados: 31
Autores: Fritsch,   David A.; Collins,   Alan R.
Centralized, off-farm compost facilities were evaluated as a disposal option for poultry litter.  Disposal fees to growers were required to develop an economically feasible facility for a private investor.  The potential for a compost facility to compete with current litter alternatives depends upon development of compost markets comparable to urban areas along with a depressed market price for litter.  Given disposal fees and uncertainty associated with market development, further expansion of land application and cattle feeding disposal alternatives is recommended.

The paper is organized into three major sections. The first section considers agricultural production prior to German reunification in 1990. It looks at the agricultural production structure in the region prior to the division of Germany in 1945 as well as the patterns which arose under the communist government. The second section starts with the 1989 situation and then discusses the initial adjustments seen as market forces are introduced -- 1990 and 1991. The third section builds upon this base to speculate on how the production structure will unfold in the future.

The central objective of this study was to estimate the implicit marginal prices for the following attributes of hybrid seed corn:  yield, moisture content, root lodging, stalk lodging, stand survival and ear drop.  This study fills an existent gap in the application of a hedonic price technique to agricultural commodities. A hedonic price equation was constructed and estimated using characteristics data on hybrid corn varieties obtained from the Iowa State University Extension Service.  Seed price data were solicited from seed companies for the same set of hybrids.  In total, fifty-nine seed companies were asked for suggested retail prices for their hybrids.  Forty companies responded with 1991 price information which was used in estimating the parameters...

Poverty - Dynamic and Sustainability Perspectives Implications for Welfare and Policy with Reference to India
Provedor de dados: 31
Autores: Tisdell,   Clement A.
After outlining some comparative features of poverty in India, this article reviews critically recent literature on the dynamics of poverty.  On economic efficiency grounds, it rejects the view that the chronically poor are more deserving than the non-chronic poor of poverty assistance.  Mechanisms of households and communities for coping with poverty are discussed.  The possibility is raised that where poverty has been persistent that rational methods for coping with it are likely to be well established, and less suffering may occur than for households and communities thrown temporarily into poverty.  However, situations can also be envisaged where such rational behaviours deepen the poverty trap and create unfavourable externalities for poverty...

Milk sold per cow, machinery expense per COW, feed expense as a percentage of net milk receipts, hired labor expense per cow, "mailbox" milk price, and percentage of total farm receipts from dairy were the most consistently important explanatory variables. Herd size was inconsistent, statistically significant in only two models.

URBAN ENVIRONMENTAL SERVICES IN DEVELOPING COUNTRIES
Provedor de dados: 31
Autores: Coolidge,   Jacqueline G.; Porter,   Richard C.; Zhang,   Z. John.
As cities in the developing world grow, their poor residents are being deprived of services, especially water, sewer, and solid waste collection, that can only be purchased expensively in private markets.  But the inadequate provision of urban environmental services is not inevitable.  A lack of will in this respect is partly due to an ambivalent attitude toward city growth and a widespread feeling that rural-urban migration is excessive.  Provision of optimal urban environmental services is also expensive.  While the budget problems are exacerbated by foolish pricing policies and cost inefficiencies, it may not be feasible for developing countries to provide all urban residents with optimal service levels.  There are many ways to provide basic services to...

Generic Advertising Wearout
Provedor de dados: 31
Autores: Kinnucan,   Henry W.; Chang,   Hui-Shung (Christie); Venkateswaran,   Meenakshi.
Advertising wearout, defined as the declining effectiveness of a commercial or campaign associated with increased exposure, is examined from a generic advertising perspective. Generic advertising campaigns of the type typically undertaken by agricultural commodity groups differ from branded advertising in that the former seek to increase aggregate demand for a product category (e.g., beef, milk, wool) rather than the market share of a particular brand within a category. A major hypothesis addressed in this research is whether generic campaigns are subject to the same generation-satiation-decay cycles found for the more typical brand advertising campaigns. The hypothesis is examined by estimating a time-varying parameter model using data from the first...

A GSD ESTIMATION OF THE RELATIVE WORTH OF COVER CROPS IN COTTON PRODUCTION SYSTEMS
Provedor de dados: 31
Autores: Giesler,   G. Grant; Paxton,   Kenneth W.; Millhollon,   E.P.
Cover crops can help reduce the negative environmental impacts of cotton production. Using time series yield data, this study utilizes generalized stochastic dominance to evaluate the relative worth, via risk premiums, of three cover crop and two conventional production systems based on expected net returns of each system and decision maker risk attitude. Results indicate, within the limitation of the study, two cover crop regimes possess a high degree of dominance over conventional systems. Determination of the dominant regime depends upon the risk attitude of a specific decision maker. This research suggests cover crop production systems may be feasible alternatives to conventional practices.

Efficiency Aspects of Transferable Dairy Quotas in New South Wales: A Linear Programming Approach
Provedor de dados: 31
Autores: Tozer,   Peter R.
In July 1990 the New South Wales Dairy Corporation altered the regulations governing the transferability of market milk supply quotas. These changes allow producers to trade in milk quotas to suit their individual production patterns. In this study, a farm-level analysis of the effects of changes in dairy quota policy in New South Wales was undertaken. In addition, an indication of the effectiveness of these changes, with respect to the original objectives of the policy makers, is provided. This research was based on a linear programming model designed to select the optimal farm plan, including quota transactions and milk production patterns. It was found that a farm could produce more milk for less cost, under a transferable quota scheme, than under the...

VALUING AMBIGUITY: THE CASE OF GENETICALLY ENGINEERED GROWTH ENHANCERS
Provedor de dados: 31
Autores: Buhr,   Brian L.; Hayes,   Dermot J.; Shogren,   Jason F.; Kliebenstein,   James B.
A split-valuation method is developed and implemented to elicit the willingness to pay to consume- or avoid consuming- a product of ambiguous quality. The split-valuation method uses experimental auction markets to separate and value the positive and negative attributes of the ambiguous good. The results show that the method can be used to successfully value a good ambiguous quality. Our application reveals that for a sample of students at a midwestern land-grant institution, the average respondent is willing to pay a premium for meat produced with the use of a genetically engineered growth enhancer that has 30% to 60% fewer calories and is 10% to 20% leaner.

MODELING PERENNIAL CROP SUPPLY: AN ILLUSTRATION FROM THE PECAN INDUSTRY
Provedor de dados: 31
Autores: Elnagheeb,   Abdelmoneim H.; Florkowski,   Wojciech J.
Two methodological approaches were applied to estimating the number of non-bearing trees in the absence of such date using data for the Southern USA pecan industry.  The first approach distinguished between bearing and non-bearing phases of a tree life and directly estimated the number of non-bearing trees.  The second focused on indirect estimating of the non-bearing tree number from changes in production.  This approach relaxed the assumption of maintaining maximum yields for infinite period as used in earlier studies.  Empirical applications used two data sets from the pecan industry.  The comparison of empirical results suggested that the first method was more accurate than the alternative approach in predicting the number of newly planted trees over...

An Assessment of U.S. Market Access for Traditional and Nontraditional Agricultural Exports Under the  Caribbean Basin Initiative
Provedor de dados: 31
Autores: Ames,   Glenn C.W.
The Caribbean Basin Economic Recovery Act (CBERA) provides duty-free access for Caribbean and Central American products entering U.S. markets. This paper compares the performance of traditional agricultural exports (beef, bananas, coffee, sugar and tobacco products) and nontraditional exports (pineapples, melons, fresh citrus, frozen orange juice and vegetables) under the CBERA. The decline in the value of traditional agricultural exports exceeded the gains in nontraditional exports by 400 percent. Tariffs and a limited range of duty-free goods still constrain CBERA’s development potential despite gains under the amended legislation.

Legal Rights of Debtors and Creditors, Bankruptcy for Financially Distressed Farmers
Provedor de dados: 31
Autores: Saxowsky,   David M.; Petersen,   Gary J.
Bankruptcy is a federal court procedure intended to benefit both debtors and creditors if a debtor is unable to pay all obligations. Filing bankruptcy' stops, or stays, all creditor's debt-collection procedures. The stay is to prevent some creditors from receiving more than their fair share from a financially distressed debtor. A bankruptcy trustee is usually appointed to assist in the fair distribution of the debtor's property. Equitable distribution of the debtor's property also is furthered by the trustee's avoidance powers, the debtor's exempt property, and the court's discharging the debtor from unpaid obligations. There are two basic types of bankruptcy proceedings--liquidation and reorganization. Chapter 7 liquidation provides for the sale of the...

The Evolution of Property Rights to Land in Sarawak: An Institutionalist Perspective
Provedor de dados: 31
Autores: Cramb,   Rob A.
The paper examines the evolution of customary land tenure in Sarawak. It first reviews economic theory relating to the evolution of land tenure, then outlines the tenure system of the !ban, the major indigenous group in Sarawak. The impact of the Sarawak state on customary tenure is examined for the Brooke period (1841-1941), the British colonial period (1946-63) and particularly the period since the formation of Malaysia (1963 to present). The paper concludes that both economic and political factors have affected the evolution of property rights to land in Sarawak.

PRICE COMPETITION BETWEEN NATIONAL BRAND AND PRIVATE LABEL FOOD PRODUCTS: 1966-1992
Provedor de dados: 31
Autores: Rodgers,   Trey; Ali Jafri,   S. Hussain; Padberg,   Daniel I.
The presence and behavior of private labels add a significant dimension to price competition among the food system's subsectors. Recent surveys in two college towns in Texas show a larger price difference between national brands and private labels than previous studies. The increase in price differences are attributed to "horizontal" and "vertical" influences on prices and also to advertising and the proliferation of brands. This competitive process gives the consumer the advantage of new products and products with brand appeal (national brands) as well as low cost copies (private labels) of these successful products.

SCHISTOSOMIASIS AND WATER RESOURCES DEVELOPMENT: A RE-EVALUATION OF AN IMPORTANT ENVIRONMENT-HEALTH LINKAGE
Provedor de dados: 31
Autores: Grosse,   Scott.
Many people argue that water resource development projects have negative health effects.  In particular, they claim that an increase in schistosomiasis almost automatically results from building dams, irrigation systems, and other water-related activities in regions endemic for the disease.  However, this literature review finds many cases where no such increase seems to occur.  Some people explain this phenomenon by the adopting of preventive measures, such as providing adequate sanitary and water facilities and appropriate water management practices.  Even when these are absent, there is often no increase in schistosomiasis transmission.  Ecological variations in snail populations may be more important. Generalizations are usually misleading.

MODELING ADVERTISING CARRYOVER IN FLUID MILK: COMPARISON OF ALTERNATIVE LAG SPECIFICATIONS
Provedor de dados: 31
Autores: Venkateswaran,   Meenakshi; Kinnucan,   Henry W.; Chang,   Hui-Shung (Christie).
The performance of restricted estimators such as Almon and Shiller in modeling advertising carryover is tested and compared to the unrestricted OLS estimator, using 1971-1988 monthly New York City fluid milk market data.  Results indicate that in the absence of autocorrelation and multicollinearity among the lagged advertising variables, the unrestricted OLS estimator is still the preferred estimator, based on Mean Square Error and Root Mean Square Percent Error criteria.  In this case, the Almon and Shiller estimators perform equally well, although next only to the OLS estimator.  In the presence of autocorrelation or multicollinearity however, the restricted estimators may outperform the OLS estimator, in a MSE sense, with the flexible Shiller estimator...

The U.S. government’s export promotion programs for red meats and the U.S. trading situation for red meats are reviewed. The Cooperator Market Development Program (CMDP), Target Export Assistance (TEA), and Market Promotion Programs (MPP) are examined with respect to expenditures for activities and regions. While generic consumer promotions accounted for the largest percentage of funding for activities, more than half of CMDP expenditures and roughly three quarters of TEA/MPP expenditures for red meats between 1986 and 1991 were allocated to Pacific Rim markets. Japan, the largest U.S. export market, received majority of regional funding during the period.

Provedor de dados: 31
Autores: Boyd,   Roy; Uri,   Noel D.
This study examines the effect of the sugar tariff-rate import quota program on the U.S. economy. Based on a computable general equilibrium model, the analysis suggests that a complete elimination of the sugar program will reduce output for all producing sectors by about $2.85 billion. For producing sectors in addition to the agriculture-program crops, crude oil and petroleum refining sectors, output will increase by about $2.98 billion. Additionally, there will be an increase of about $197 million on $121 million in the consumption of goods and services and in welfare, respectively. The government sector realizes a reduction in revenue of about $15 million.

The strategic effects of subsidies on output and subsidies on investment differ substantially in dynamic models where a government's commitment ability is limited. Output subsidies remain effective even as the period of commitment vanishes. but investment subsidies may become completely ineffective. This difference has been obscured because most existing models of strategic trade policy are static.

THE U.S. APPLE INDUSTRY: ECONOMETRIC MODEL AND PROJECTIONS
Provedor de dados: 31
Autores: Willett,   Lois Schertz.
A dynamic model of the U.S. apple industry, including relationships for bearing acres, production, utilization, and allocation to the fresh, canned, frozen, juice, dried and other markets, is specified.  Demands for each of these markets are modeled.  Model coefficients are obtained using Zellner's seemingly unrelated regression procedure and data from 1971 through 1990.  Elasticities and flexibilities are compared with other studies.  Projections indicate that price fluctuations will continue in the industry when acreage is held at 1990 levels.  A ten percent increase in fresh exports strengthens all apple prices.  However, a ten percent decrease in the price of juice imports mitigates some of this effect.

Estimation of Factor Demand and Substitution in the Australian Pig Industry: A Dual Approach
Provedor de dados: 31
Autores: Buetre,   Benjamin L.; Ahmadi-Esfahani,   Fredoun Z.
This study seeks to estimate the rate by which inputs in Australian pig production are substituted for one another when prices change. It employs a dual approach to response analysis. Using cost shares of inputs and input price indexes for the period 1977-78 to 1990-91, a set of equations derived from a transcendental logarithmic function is estimated with symmetry and homogeneity constraints imposed. The results indicate that, with the exception of the demand for feed which is a vital production input, pig producers are very responsive to own price changes. The estimated elasticities generally differ in magnitude from similar studies of the Australian agricultural sector, and suggest that, at a lower level of aggregation, farmers are more flexible in...

Poverty, Household Food Security, and Nutrition in Rural Pakistan
Provedor de dados: 31
Autores: Alderman,   Harold; Garcia,   Marito.
Designing strategies and policies that will alleviate poverty and improve household food security and nutritional well being is one of the most important challenges facing government policymakers in developing countries. The choice of strategies and policies depends in large part on understanding the dynamics of poverty, especially the mechanisms by which households acquire and spend income and cope with cries such as poor harvest or loss of employment. This work by Harold Alderman and Marito Gracia represents IFPRI's first comprehensive analysis of the longitudinal data on 800 households collected between 1986 and 1989 in Pakistan. This unique data set enables researchers to examine the temporal dimensions of food security, income and labor dynamics,...

Two Government Failures? A Tale of Sugar and Wool
Provedor de dados: 31
Autores: Edwards,   Geoff W.
A discussion is provided of policy developments and policy debate for the sugar and wool industries in 1992 and the first half of l993. The discussion is set against a characterisation of the longer-term economic situations of the two industries. It is suggested, perhaps controversially, that government failure has been a longstanding feature of both industries. Understanding of the policy reform needed to remove economic inefficiency is better for sugar than for wool. However, the decisions taken on sugar policy in February, 1993 mean that incentives for wasteful use of resources are maintained. In the case of wool, the Gamaut inquiry faces a challenge in trying to come to grips, in a period of three months, with the major short- to medium-term problems...

Producers and marketers of agricultural commodities are often beset with a similar set of problems that generally may be reduced to the following question: "how can we modify our product or program in such a way as to gain a competitive edge on our competition?" As every commodity marketer knows, there is, unfortunately, no easy answer to this question. Obtaining higher prices and returns for agricultural products is possible, but requires commitment, vision and attention to the ever-changing marketplace. The current monograph contains two case studies that approach this perennial question from different agricultural commodity industries--fresh produce and turkeys--that are surrounded by different sets of basic supply and demand conditions. Yet, in each...

STOCHASTIC ENERGY DEMAND AND THE STABILIZATION VALUE OF ENERGY STORAGE
Provedor de dados: 31
Autores: Tsur,   Yacov; Zemel,   Amos.
The economic value of energy storage to meet peak electricity demand is analyzed with an emphasis on the role of demand uncertainty. The concept of the stabilization value, which measures that part of the benefit of the storage project which is due solely to the stochastic demand components, is defined. The magnitude of the stabilization value, relative to the overall value of energy storage, is evaluated in terms of a simple model that accounts for the relevant characteristics of the electric power utility's production mix. It is found that neglecting the demand uncertainty can seriously bias the benefit assessment of the storage project as well as the determination of the optimal storage capacity.

THEPOUTICALECONOMY OF A CROP INSURANCE EXPERIMENT
Provedor de dados: 31
Autores: Skees,   Jerry R.
A new crop insurance alternative will be available for eight major crops in 1994. This paper provides background on the development and potential for the new Group Risk Plan (GRP). The policy issues surrounding the Federal Crop Insurance Program are reviewed with an emphasis on the microlevel problems. Recognition of the micro-level problems of adverse selection and moral hazard led to the development of a pilot test of GRP in 1993. Limited Federal funding and the political demands for improving the actuarial performance of the Federal Crop Insurance Program led to the rapid expansion of GRP for crop year 1994. ideas for using GRP to improve the mixture of government and private initiatives to assist U.S. farmers in managing risk are introduced.

The health care industry's far-reaching economic influence within North Dakota is the focus of this report. An input-output model is used to estimate the economic impact of hospitals and long-term care nursing facilities. The analysis shows that nearly 8 percent of the state's total business activity, nearly 10 percent of the state's total retail sales, and nearly 19 percent of the state's total employment in 1991 were attributable to hospitals and long-term care nursing facilities. In addition, these facilities generated nearly $41 million of tax revenues for the state in 1991.

Provedor de dados: 31
Autores: Erba,   Eric M.; Pratt,   James E.; Wasserman,   Walter.
A survey of the milk haulers in New York and Pennsylvania was conducted to assess the changes in the northeast milk hauling industry since 1981. Detailed information was collected on characteristics of the hauling businesses as well as the equipment operated. Some of the general topics discussed include the number of hauling businesses, the size of hauling businesses, and the cost of milk hauling equipment. To address the subject of hauling efficiency, a section describing common measures of efficiency is included. Where possible, comparisons have been made to statistics obtained from a similar study completed in 1981.

THE RELATIONSHIP BETWEEN PRICE STABILIZATION AND CYCLES IN THE CANADIAN WHEAT MARKET
Provedor de dados: 31
Autores: Clark,   J. Stephen; Klein,   Kurt K.
In this study, moving average price stabilization schemes were analyzed under the assumption of rational expectations.  It was shown that moving average price schemes may induce cyclical behavior into market prices where no cyclical pattern previously existed.  Moving average price stabilization schemes are important to Canadian agricultural policy analysis because they are a characteristic of stabilization programs in Canada.  Indeed, the Agricultural Stabilization Act, introduced in 1975, and the Gross Revenue Insurance Program, introduced in 1991, use moving average prices to calculate returns to producers.

HOW SENSITIVE ARE CROP YIELDS TO PRICE CHANGES AND FARM PROGRAMS?
Provedor de dados: 31
Autores: Choi,   Jung-Sup; Helmberger,   Peter G.
A two-stage approach is used to estimate sensitivity of corn, wheat, and soybean yields to changes in prices and land idled.  Estimated elasticity of demand for fertilizer per acre with respect to expected output price equals 0.47, 0.10, and 0.82 for corn, wheat, and soybeans.  Upper estimates of the elasticity of yield with respect to fertilizer equals +0.58, +0.29, and +0.16 for corn, wheat, and soybeans.  Yields are found to be quite insensitive to price changes.  Fertilizer demands and yields are insensitive to land idled under farm programs.

A Note Comparing Single-Index Models and Quadratic Programming Models for Farm Planning Under Risk
Provedor de dados: 31
Autores: Batterham,   Robert L.; Drynan,   Ross G.; Oarke,   D.K.; Carter,   P.H.
Single-index models from portfolio theory have previously been adapted for risk efficient farm planning in North America. The potential for using single-index models in farm planning is considered in this paper both theoretically and in the light of two illustrative Australian case studies. It is concluded that single-index models have no significant computational or other advantages over full quadratic programming portfolio selection models for farm planning and may produce relatively poor plans and poor assessments of the risks associated with those plans.

Provedor de dados: 31
Autores: Hanson,   Kenneth; Robinson,   Sherman; Schluter,   Gerald E.
The effects of a world oil price shock on U.S. agriculture are analyzed in an economywide environment. We use an input-output model to analyze the direct and indirect cost linkages between energy and other sectors of the economy. Then, to allow sectoral output adjustment and the effects on the U.S. current account, we use the U.S. Department of Agricultural/Economic Research Service  Computable General Equilibrium (CGE) model to analyze the sectoral effects under three different macro adjustment scenarios. The effects on agriculture are not limited to the direct and indirect energy costs and government support programs for agricultural also matter.

Autores: Leistritz,   F. Larry; Coon,   Randal C.; Thompson,   JoAnn M.
The basic sectors are central to the growth and vitality of any economic system, and current and accurate information regarding changes in an area's economic base is vital to local economic development planning efforts. This report provides estimates of the economic base by economic sector for North Dakota counties for the period 1960-1991. The data indicate that agriculture remains North Dakota's most important basic sector, accounting for 50 percent or more of the economic base in 31 of the state's 53 counties in 1991. The energy sectors play a significant role in the economic base of a number of western North Dakota counties. Energy extraction and conversion accounted for 50 percent or more of the economic base in seven counties in 1991. Manufacturing...

INSTITUTIONAL ISSUES AND STRATEGIES FOR SUSTAINABLE AGRICULTURE: VIEW FROM WITHIN THE LAND-GRANT UNIVERSITY
Provedor de dados: 31
Autores: Batie,   Sandra S.; Swinton,   Scott M.
Sustainable agricultural research and education have gained acceptability within the land-grant system in less than a decade, an impressive change. Attitudes were changed by a set of forces which include lobbying by sustainable agriculture advocates, requests from farmers as a result of the cost-price squeeze of the early 1980's, changing demands for both environmental quality and less pesticide residues from food consumers, and the availability of new funding sources.  Despite its hard-won acceptability, there are tensions with respect to sustainable agriculture within the land-grant system. Sustainable agricultural issues are not yet integrated into the fabric of the land-grant institution. In order to integrate it fully, challenges remain in three key...

Autores: Lesser,   William H.
Hedonic pricing is used to value certificates of plant variety protection for soybean seed in New York. The estimated price premium of 2.3 percent (.7 ¢/lb.) is low, and another indicator that US Plant Breeders' Rights protection likely provides inadequate incentives for breeding investment. Soon the Congress will decide on amending the Plant Variety Protection Act to strengthen protection. The current results suggest strengthening is needed, but additional study is required to determine if the proposed amendments are optimal.

EVALUATING ENVIRONMENTAL IMPACTS OF RURAL DEVELOPMENT PROJECTS
Provedor de dados: 31
Autores: Laarman,   Jan G.
Discussions of "sustainable development" call attention to various dimensions of human well-being to be considered concomitantly with traditional financial and economic measures. The challenge of environmental impact analysis (EIA) is to encourage re-design of projects so that net benefits are maximized over some weighting of economic, environmental, and other criteria. To date, development organizations have been under attack by environmentalists for ignoring or conveniently overlooking environmental damages of development projects.  Explanations for this include inadequate institutional commitment to link resource conservation with economic development, short time horizons, narrow evaluation criteria, problems of monetary valuation, and problems with...

Noncooperative Game Theory: A Review with Potential Applications to Agricultural Markets
Provedor de dados: 31
Autores: Sexton,   Richard J.
This paper is a survey on noncooperative game theory relevant to agricultural markets.  It is divided into two parts.  Part I discussed types of noncooperative games and reviews important developments in noncooperative game theory solution concepts, including Nash equilibrium, subgame perfect equilibrium, and perfect Bayesian equilibrium.  Strengths and weaknesses of game theory as a modelling tool are also assessed.  Part II 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, vertical control, auctions, and bargaining.   A shortened version...

SUSTAINABLE GROWTH IN AGRICULTURAL PRODUCTION: POETRY, POLICY AND SCIENCE
Provedor de dados: 31
Autores: Ruttan,   Vernon W.
In this paper I review the evolution of the sustainability concept.  This is followed by a description of three "classical" systems of sustainable agriculture.  None of these systems were or are capable of generating growth of output consistent with modern rates of growth in demand.  I then turn to three unresolved analytical issues that continue to divide the conventional resource economics and the sustainable development communities.  In a closing section I argue sustainable growth in agricultural production should be viewed as a research agenda rather than as a package of practices that is available to producers whether in developed or developing countries.

The North Dakota wild fur industry exists as a small, but important economic and recreational activity. This paper describes the role of furbearers and estimates the impact of recreational furbearer hunting and trapping on economy. Furbearers are animals whose pelts human's use for clothing. Furs are almost exclusively used for garments and trim on clothing. Furbearers are harvested for sport and for profit and to prevent damage to domestic livestock, fowl, and crops. North Dakota furbearer hunters and trappers harvest about $500,000 worth of raw furs per year. Wild fur harvesters spend $30 million each year hunting and trapping in the state. Most of these are recreational hunters and trappers, who, in the aggregate, get about $12 million in nonmonetary...

Provedor de dados: 31
Autores: Featherstone,   Allen M.; Schurle,   Bryan W.; Duncan,   Steven S.; Postier,   Kevin D.
The ultimate loss financial institutions bear for foreclosed loans is determined by their success in liquidating their acquired property portfolios. This study examines the price received for land sold by private individuals and financial institutions from 1977 through 1990. After adjusting for quality differences, financial institutions received on average 9.2% less than private individuals. Further analysis reveals that commercial banks received a discount of 5.8%, the Farm Credit System (FCS) a 9.2% discount, and Farmers Home Administration (FmHA) a 14.7% discount. For this sample of 13,375 Kansas sales, it is estimated that the sum of the transfers from financial institutions to land buyers amounted to $9.2 million.

Provedor de dados: 31
Autores: Parliament,   Claudia; Lerman,   Zvi.
This research examines the effect of risk on the proportion of equity held by agricultural cooperatives. The measured components of risk are business risk and the financial risk that is dependent on the proportion of debt in the cooperative's capital structure. The empirical results indicate the proportion of equity is inversely related to financial risk and positively related to business risk. These risk effects are estimated to differ based on the commodity handled by the cooperative. No Significant relation between the proportion of equity and whether or not the cooperative operates on a pooling basis is estimated.

A STRUCTURAL APPROACH TO ESTIMATING RATE OF RETURN EXPECTATIONS OF FARMERS
Provedor de dados: 31
Autores: Ahrendsen,   Bruce L.
A dual cost function approach is developed as an alternative to time series and simplistic approaches for estimating farmers' expected operating rates of return on assets. A translog restricted cost function is estimated using data provided by 152 North Carolina dairy farmers over the period 1976 through 1986. The predicted costs from the fitted restricted cost function are used to construct estimates of farmers' expected operating rates of return on assets. The estimates from this structural approach explain more of the variation in observed rates than do time series estimates or sample mean observed rates.

Producer Behaviour Under Strict Rationing and Quai-Fixed Factors
Provedor de dados: 31
Autores: Guyomard,   Herve; Mahe,   Louis Adrien Pascal.
The paper examines the effect of rationing outputs and inputs on producer behaviour. Full representation of the modified supply-demand system after rationing, including shadow prices for the constrained netputs, is derived from the unrestricted profit function before rationing, and vice-versa. Attention is focused on cross-price effects which have been less explored than own-price effects which obey to the Le Chatelier principle. The theoretical framework is applied to the EC agricultural sector in order to analyse the effects of output and input rationing on the production structure of the EC agricultural sector, with emphasis on the impact of the milk quota constraint on unrestricted output supplies and input demands.

An eight-sector, single-period, agricultural-focused computable general equilibrium (CGE) model of Malaysia using 1983 as the base year was developed to evaluate effects from changes in the external trade environment and domestic economic policies. The simulation results demonstrate the growing resiliency of the increasingly diversified Malaysian economy to external shocks. Also, they point to the domestic economy's ability to buffer internal policy-induced distortions.

The period under review has been one of steady consolidation rather than spectacular change. The agricultural sector has accommodated itself to the deregulated environment and has indeed benefited from the macro-economic emphasis on stable exchange rates and low interest rates. Further reform of the state marketing boards has proceeded; the situation exacerbated by a failure of the Kiwifruit Marketing Board to control its payouts within current income. Over the period 1984 to 1993 there has been sustained growth in real net output of agriculture reflecting a considerable improvement in the use of resources. Incomes in the sheep and beef sector have been static in the period but not disastrous, and the dairy sector continues in a phase of steady growth in...

The Economics of Institutional Change In Agriculture
Provedor de dados: 31
Autores: Barlow,   Colin; Quizon,   Jaime.
The key role of institutions in mediating rural markets, and thus in influencing economic change in agriculture, is explored. Pertinent theories of institutional change are reviewed and the place of external intervention, whereby outside agencies attempt to assist market mediation, is examined. The institutional cases of plantations and smallholdings in tree crop agriculture are scrutinised, and their respective performances are compared with a focus on market failures. The case of traditional land rights is investigated in similar vein. The analyses indicate that government interventions to remedy market failures may be helpful in improving information, capital, land, and output markets, but should be carefully designed to match economic and social...

Autores: Smith,   Rodney B.W.; Gardner,   Bruce L.
This paper attempts to improve our understanding of the effects of market prices on cattle marketing decisions, using futures prices as measures of unobserved price expectations.  This approach has been used successfully in explaining feeder cattle placements, but not in marketings.  Our aim is to provide empirical evidence on an unresolved issue in cattle marketing, the differential effects of the current price and near-term price expectations.  When the cash price of fed cattle rises, the higher returns from current sales encourage increased marketings; yet, if the price is expected to remain high it may pay to feed cattle longer, holding them back from current marketing.  By estimating marketings as a function of cash and futures prices simultaneously...

RISK AND PROBABILITY PREMIUMS FOR CARA UTILITY FUNCTIONS
Provedor de dados: 31
Autores: Babcock,   Bruce A.; Choi,   E. Kwan; Feinerman,   Eli.
The risk premium and the probability premium are used to determine appropriate coefficients of absolute risk aversion under CARA utility. A defensible range of risk aversion coefficients is defined by the coefficients that correspond to risk premiums falling between 1 and 99% of the amount at risk or to probability premiums falling between .005 and .49 for a lottery that pays or loses a given sum. The consequences of ignoring risk premiums when selecting risk-aversion coefficients for representative decision makers are illustrated by calculation of the implied risk premium associated with the levels of absolute risk aversion assumed in six selected studies.

OPTIMAL HOG SLAUGHTER WEIGHTS UNDER ALTERNATIVE PRICING SYSTEMS
Provedor de dados: 31
Autores: Boland,   Michael A.; Preckel,   Paul V.; Schinckel,   Allan P.
Three hog genotypes are simulated to determine how producer profits, economically optimal slaughter weights, and carcass component weights change under three pricing models.  Live weight pricing pays more for the fatter barrows whereas a three component (separate payments for fat, lean, and byproducts) and six component (separate payments for major primal cuts, other lean, fat, and byproducts) pricing system pay more for the leaner gilts.  Implications for selection of genetic stock and pricing system are presented.

ON PRICE RISK AND THE INVERSE FARM SIZE-PRODUCTIVITY RELATIONSHIP
Provedor de dados: 31
Autores: Barrett,   Christopher B.
The oft-observed inverse relationship between farm size and productivity is generally explained by labor market imperfections. Although other explanations exist (e.g., size-sensitive cropping patterns and variable soil quality), the literature ignores uncertainty as an explanation. Using a simple two-period model of an agricultural household that both produces and consumes under price uncertainty at the time labor allocation decisions are made, this paper demonstrates analytically that an inverse relationship may exist, even absent any of the more common explanations. A simple data exercise suggests the plausibility of temporal price risk as an explanation for this phenomenon.

Technology Adaptation and Adoption: The Experience of Seed-Fertiliser Technology and Beyond
Provedor de dados: 31
Autores: Byerlee,   Derek R.
Technical change in agriculture is examined for two contrasting situations in the developing world: the largely irrigated wheat-based systems of South Asia, where improved seed-fertiliser technology has been widely used for more than two decades, and rainfed maize-based systems of sub-Saharan Africa, where adoption of this technology remains incomplete. Zones of medium to high production potential and relative land scarcity are the primary focus of the analysis. Experience with the adoption of seed-fertiliser technology in these areas helps to identify the key changes in institutions and policies needed to foster continuing growth in food grain production by small-scale farmers, especially changes in research and extension strategies and in input supply...

LABOR MARKET INCENTIVES TO STAY IN SCHOOL
Provedor de dados: 31
Autores: Stallmann,   Judith I.; Johnson,   Thomas G.; Mwachofi,   Ari; Flora,   Jan L.
Human capital theory suggests that job opportunities will create incentives for human capital investment. If job information does not flow freely, or if  they prefer not to move, students will make investment decisions based upon local job markets. Communities with a high percentage of low-skill jobs which do not reward high school and higher education do not create incentives for students to finish high school or continue beyond high school. Data from Virginia support this hypothesis. Targeted job creation, and improved labor market information may create incentives for increased human capital investment in many rural communities.

Simulation of nonparametric efficiency shows that even when the number of firms is large, defining ten or more inputs results in most firms being efficient. Comparison of empirical with simulated results suggests that the dimension of the problem rather than actual efficiencies has the greater effect for some empirical results.

ALTERNATIVE BREEDING INVENTORY SPECIFICATIONS IN A LIVESTOCK MARKET MODEL
Provedor de dados: 31
Autores: Vere,   David T.; Griffith,   Garry R.; Bootle,   B.W.
The procedures adopted for incorporating breeding decisions in a livestock market model have implications for the simulation of the model. Specifically, there is a need to consider the nature of the biological lags between livestock breeding decisions and outputs, and how these are incorporated in the breeding inventory used in such a model. In this paper, five alternative breeding inventory specifications are used in a structural econometric model of the Australian prime lamb market. The predictions of lamb slaughterings and of price responses of lamb producers are affected by the specification of the lamb breeding inventory used. The extent to which the modelling results approximated reality was substantially improved when disaggregated and seasonally...

This article reviews various models that may be used to explain optimal leverage choice for the proprietary farmer in a stochastic dynamic environment and develops a new model that highlights the risk of failure rather than the usual concept of risk as the variability of wealth. The model suggests that in addition to the usual factors, farm financial leverage is affected by age, wealth, and the opportunity cost of farming.

"ECONOMIC CORRECTNESS" AND AGRICULTURAL ECONOMICS

Autores: Christy,   Ralph D.
This address is directed toward applied economists as they provide information to private and public decision makers. Central to this discussion is the role of markets as institutions in achieving society's desired ends. Current "economic correctness" -the view that unfettered markets are superior in achieving efficiency, growth, and welfare- has attempted to return a larger role to the private sector, but the relative roles of market-oriented versus government-oriented solutions to problems are often not well appraised. Views presented herein calls for agricultural economists to move simultaneously toward an understanding of the strategic behavior of firms in imperfectly competitive markets and toward an adoption of policy analysis consistent with a...

The Agricultural Business Management Program: Lessons Learned at Oregon State University
Provedor de dados: 31
Autores: Lindsey,   Patricia J.; Martin,   Michael V.
This study argues that the uniqueness of the agricultural industry justifies the development of agribusiness as an alternative degree major within traditional agricultural economics department. Successful curricula must focus on elements of decision making that are unique to agricultural business industries. In particular, agribusiness program should complement and not duplicate the curricula offered by business school. Special characteristics of agriculture were identified and presented as the conceptual framework for agribusiness programs. Using Oregon State University as a case study, the analysis examines in depth the experiences and lessons learned from its implementation of agribusiness management programs.

Micro-Level Approaches to Analysing Rural Development Problems
Provedor de dados: 31
Autores: Fleming,   Euan M.; Hardaker,   J. Brian.
Micro-level analyses of the farm sector may be conducted at intra-household, household or village levels. Most economists have preferred to work at the household level because of the existence of a well-developed farm-household theory. Empirical studies at the micro level have mostly used econometric or mathematical programming approaches. For both, but especially the former, the strong assumption of separability of production and consumption decisions is usually crucial. While the number and sophistication of empirical studies continue to grow, operational shortcomings remain severe. The limited use in policy making of many analyses is noted and the merits of combining comprehensive formal models with less formal and relatively simple approaches are...

This summary and analysis of 357 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 123 cows per farm and 18,789 pounds of milk sold per cow in 1992, 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 $45,274 per farm. The rate of return...

Experimental markets can be a useful tool to guide and evaluate environmental policy.  This paper reviews four experiments to illustrate.  Two institutional experiments are considered-Coasian bargaining with positive transaction costs, and a gaming experiment of dynamic choice in a conflict.  Two valuation experiments are also discussed-the impact of sequential reduction mechanisms on the value of risk, and experimental auction markets to elicit the value of safer food.

THE EFFECTIVENESS OF STATE LOGOS FOR FARM-RAISED CATFISH

Product differentiation can consist of identifying the corporate firm that produces the product (such as Kraft) or the producer cooperative that produces the product (such as Ocean Spray). The Catfish Institute (funded by producers, feed mills and processors) was created to promote the generic sales of farm-raised catfish. Also, a number of Mississippi catfish processors are differentiating their product by promoting it as Mississippi Farm-Raised Catfish.  Louisiana farm-raised catfish are highly comparable in breeding, feeding and processing to catfish marketed as Mississippi Farm-Raised Catfish. Use of a state logo is based o the premise that loyalties tend to encourage food consumers to patronize local producers. Louisiana State University Agricultural...

This paper analyzes the determinants of variation across industries in levels of intra-industry trade (IIT) for a sample of thirty-six U.S. processed food and beverage industries in 1987, previous studies of intra-industry trade having focused on industry characteristics in the manufacturing sectors.  The determinants predicted by IIT theory are measures of product differentiation, economies of scale, and imperfect competition; the results of this analysis indicate that IIT variation across the food and beverage industries is positively related to product differentiation, economies of scope, and similarity of tariff barriers among trade partners, but negatively related to industry concentration.

The Failure of Strategic Industrial Policies Due to the Manipulation by Firms

The strategic effects of subsidies on output and subsidies on investment differ substantially in dynamic models where a government's commitment ability is limited. Output subsidies remain effective even as the period of commitment vanishes, but investment subsidies may become completely ineffective. This difference has been obscured because most existing models of strategic trade policy are static.

RURAL DEVELOPMENT, PRIVATIZATION AND PUBLIC CHOICE: SUBSTANCE DEPENDS UPON PROCESS
Provedor de dados: 31
Autores: Hite,   James C.
Whether or not privatization facilitates rural development depends upon what rural development means. In practice, rural development often is the result of a struggle between rent defenders and rent seekers. A positivist concept of rural development is proposed, and the institutions of public choice are examined to determine how they might influence privatization decisions. The conclusion is that whether or not privatization improves efficiency of adjustment in rural economies depends upon the specifics of political deals required to achieve a particular act of privatization.

The principal objective of this study is to determine the financial impacts of changing feed procurement strategies for a specified southeastern Minnesota dairy farm.  Growing all feed for the dairy herd on the farm itself, currently the most prominent mode of procurement, is compared to: (1) producing all forage and purchasing all concentrate feeds from others, and (2) purchasing all feeds from others.  The effect of herd size on the comparisons is considered to determine if size has a bearing on the chosen method of feed procurement.

THE DISTRIBUTION OF FULL INCOME VERSUS MONEY INCOME IN THE UNITED STATES
Provedor de dados: 31
Autores: Thomas,   Saji; Senauer,   Benjamin.
This paper compares the distribution of money income and full income across households in the United States.  The concept of full income was introduced in Becker's household model and provides a framework for estimating the economic value of productive non-market activities and leisure.  If the allocation of time is voluntary, full income may be a better measure of economic welfare than money income.  Non-parametric Lorenz curves and Gini coefficients are used to compare the two distributions.  The data are from the Census Bureau's Survey of Income and Program Participation for 1984-86.  Full income is more equally distributed than money income.  However, the distribution remains very unequal.  The income distributions are also compared for specific types...

Foi realizada a avaliação do desempenho de equipamento experimental para a determinação de curvas de umidade de equilíbrio - isoterma de adsorção - de farinhas pelo método dinâmico. Para o ajuste dos valores definidos (0,51; 0,57; 0,67; 0,75; 0,79 e 0,81) de atividade de água - Aa - na corrente de ar, foram usadas soluções saturadas de sais. A comparação da eficiência do equipamento, com e sem recirculação de ar, foi feita determinando-se a isoterma de adsorção de farinha de soja a 35°C. A versão com recirculação de ar permite a obtenção de dados de equilíbrio em elevados níveis de Aa, nos quais há perda das amostras por crescimento microbiano quando se emprega a versão sem recirculação. Os tempos necessários para a obtenção do equilíbrio da farinha com as...

Geometria fractal em física do solo
Provedor de dados: 63
Autores: Bacchi,O.O.S.; Reichardt,K.
A geometria fractal tem sido aplicada nos mais diversos ramos da ciencia, mostrando grande potencial na descrição de estruturas altamente complexas. A sua aplicação em ciência do solo tem despertado grande interesse e vem se intensificando nos últimos anos. Apesar da sua divulgação através da literatura científica internacional, de conhecido acesso por parte dos pesquisadores brasileiros, o assunto parece não ter merecido ainda a nossa atenção, a contar pela ausência do tema em nossas revistas especializadas. Tratamos aqui da conceituação básica dessa nova abordagem e de algumas aplicações em física do solo.

Autores: Falleiros,M.C.; Ravelo Sanchez,A.; Souza,M.Dornelas de; Bacchi,O.O.S.; Pilotto,J.E.; Reichardt,K.
The problem of neutron probe soil water content measurements close to soil surface is analysed from the spatial variability and also from the slow neutron "loss" to the atmosphere points of view. Results obtained on a dark red latosol of the county of Piracicaba,SP, indicate the possibility of precisely measuring the neutron "sphere of influence" when different media are used on soil surface.

Autores: Ono,E.O.; Rodrigues,J.D.; Sabino,J.C.; Pinho,S.Z. de.
O presente trabalho teve como objetivo, verificar o tempo de armazenamento necessário para que seja atingida a viabilidade máxima e o tempo de embebição máxima de sementes de macadâmia (Macadamia integrifolia Maiden &amp;amp; Betche var. IAC-4-20). As sementes foram pesadas e colocadas em recipientes com água para que ocorresse o processo da embebição, sendo realizada a pesagem a cada 6 horas. Pode-se concluir que a embebição foi máxima ao redor de 90 horas após o início da embebição. Para a análise da viabilidade das sementes, estas foram semeadas mensalmente, durante 12 meses a partir da colheita. Verificou-se que a viabilidade máxima das sementes é atingida, 4 meses após o início do armazenamento.

Fatty acid composition of commercially important fish from Brazil
Provedor de dados: 63
Autores: Gutierrez,L.E.; Silva,R.C.M. da.
Total fat and fatty acid composition of seven fresh-water and nine marine fish commercially important in Brazil were determined. Palmitic acid was the predominant saturated fatty acid in both freshwater and marine fish. In the fat from freshwater fish the total C-16 fatty acids were higher than in marine fish. Oleic acid was the most abundant monounsaturated fatty acid and it was found in higher levels in freshwater fish. The data revealed that most freshwater fish from Brazil examined were a poor source of eicosapentaenoic (20:5) and docosahexaenoic (22:6) acids. Of the marine fish analysed, only sardine and manjuba could be recommended as a good sources of n-3 fatty acids.

Changes in trehalose content of baker's yeast as affected by octanoic acid
Provedor de dados: 63
Autores: Gutierrez,L.E.
Octanoic acid inhibited ethanolic fermentation by Saccharomyces cerevisiae (bakers yeast) and the trehalose accumulation, however did not affect the endogenous degradation of trehalose. This inhibition may be explained by the binding of octanoic acid to hexokinase or other proteins of plasma membrane because they are not necessary for endogenous fermentation. The degradation of trehalose may be due to an activation of trehalase.

Aflatoxin removal of peanut meals with aqueous ethanol
Provedor de dados: 63
Autores: Fonseca,H.; Regitano-d'Arce,M.A.B.
A preliminary approach to achieve compatible simultaneous extraction of aflatoxin and residual oil from pressed oil meals was conducted to determine the minimum amount of water to be added to ethanol versus necessary time to achieve complete removal of aflatoxin. Commercial anhydrous, 96, 93 and 90°GL ethanol were utilized in trials with Soxhlet extractors. Commercial anhydrous ethanol did not remove aflatoxin completely and the extraction efficiency in minutes was directly proportional to the amount of water present in the ethanol, as expected. Although 96°GL ethanol was efficient, alcoholic strengths between 96 and 99°GL need be evaluated to improve oil extraction, provided they do not decrease aflatoxin removal efficiency.

Autores: Gutierrez,L.E.
A study was carried out in order to determine the effect of vitamins (biotin, thiamine, pantotheniic acid and pyridoxal) and micronutrient (zinc, boron, manganese and iron) deficiencies on higher alcohol production during alcoholic fermentation with the industrially used yeast Saccharomyces cerevisiae M-300-A. Zinc deficiency induced a reduction on the levels of isobutyl and isoamyl alcohols. An increase on isobutyl alcohol (fivefold) and a reduction of isoamyl alcohol (two fold) and n-propyl alcohol (three fold) contents resulted from pantotheiiic acid deficiency, whereas pyridoxal deficiency caused an increase on the levels of isobutyl and isoamyl alcohols. Biotin was not essential for the growth of this strain.

Autores: Nogueira,J.N.; Cantarelli,P.R.; Gallo,C.R.; Moreno,I.A.M.; Matsuura,F.C.A.V.
O presente trabalho foi desenvolvido com o objetivo de fornecer informações, não encontradas na literatura, sobre o efeito da acidificação (cinco ácidos orgânicos), fermentação e adição de cálcio na qualidade de couve-flor (cultivar Shiromaru III), processada pelo calor. A qualidade da couve-flor processada foi avaliada através de análise física, química, microbiológica e sensorial, após dois meses de armazenamento à temperatura ambiente. Os resultados mostraram a possibilidade de processar couve-flor enlatada, de alta qualidade, em pequenas indústrias, com redução de gastos em equipamentos, instalações e energia. O procedimento da acidificação oferece também uma segurança maior para o consumidor, pois elimina possíveis riscos de incidência do botulismo.

Pupae of Anastrepha suspensa (Loew) were irradiated 2 days before adult eclosión in an air atmosphere with 15, 20, 25, 30, 50 and 70 Gy of gamma radiation (Co-60). The radiation effects on sterility and other parameters of quality and behavior of males and females of caribfly were established. Males became fully sterile with a dose of 50 Gy and females laid no eggs when exposed to 25 Gy. Radiation had no significant effect on adult eclosion, sex ratio, flight ability and irritability, but female mortality was affected significantly by radiation, showing higher survival rates in low dosage treatments. The mating behavior of the males was reduced significantly by increasing the radiation doses.

Autores: Gutierrez,L.E.; Silva,R.C.M. da.
Lipid extract and fatty acid composition of cane molasses and yeasts (Saccharomyces cerevisiae M-300-A and Saccharomyces uvarum IZ-1904) grown in molasses medium were determined. In molasses, linoleic acid was found in higher levels (around 42%) and was followed by palmitic, oleic and linolenic acids. The lipid extract varied from 1.02 to 3.13 gkg-1. In yeasts, the level of lipid extract varied from 16.65 to 31.12 g.kg-1 (dry matter basis) depending on the molasses type and yeast species. Both yeasts were able to incorporate fatty acids from molasses' and therefore linoleic and palmitic acids were the major fatty acids found in them.

Experiment on banana flour production is presented. The varities of banana used in this study were Klue numwa and Klue hakmuk. The effect of heat pretreatment on peeling and cutting under pressure at 250"F were investigated. It was shown that heating for I min. gave the best result on peeling and cutting. The proximate analysis at different heating times yielded similar results. However, the percent amylose content to dry basis of Klue numwa and Klue hakmuk flours were 12.06 and 10.58, respectively. The physical properties of Klue numwa and Klue hakmuk flour were also studied. The swelling and gelatinization properties of Klue numwa flours was similar to rice starch while Klue hakmuk flour was alike that of glutinous rice starch. The mixture of Klue nLlmwa...

The digestive gland of Phyllocaulis soleiformis is a compound tubular gland. The secretory tubules are made up of two main cell types: the digestive cells and calcic cells. The digestive cells are the most numerous, usually columnar, and exhibit three different functional stages: absorptive, secretory and excretory. These cells contain two cytoplasmic granules types and, in the excretory stage, most of the cell is occupied by a large vacuole. The calcic cells occursingly or frequently in groups of two or three, are triangular shaped and have distinct apical granules, and yet calcic histochemical detected granules. In addition, there is a third cell type, without characteristic cytoplasmic granules and which correspond to the undifferentiated cells. The...

In Partamona cupira, caste determination follows the general patterns of Trigonini bees. The effects of the juvenile hormone and the amount of food on the process were studied. The frequency of queens increased with the quantity of food ingest by the larvae and or whith the amount of juvenile hormone topically applicated. Queens emerged earlier than workers. Intercastes were not found, sugesting that castes differentiation is a canalised process in this species.

In nature, the Sciaridae live in moist and shady places, where exists vegetable material in decomposition. It is very dificult to determine the proper Sciaridae's alimentary habit and then, it is dificult, also, to rear Sciaridae species in laboratory. To improvement the Bradysia hygida rearing, the objectives of this research were to analyse the nutritive value of mucuna bean foliage for the larves, to verify the role of the ground (as larvae substrate and in diet composition) and also to verify the possibility of ground substituition by another kind of substrate. Two kinds of sand were employed in the place of the ground and three diets, free of ground, were prepared. The parameters analysed were: duration of the life cicle, porcentage of emergence, egg...

Trichogenes longipinnis (Britski &amp;amp; Ortega, 1983) is a leather fish restricted to the rivers on the shore in the southeast of Brazil. In this work, the oesophagous structure is being showed. The oesophagous appears itself short, dorsally inclinated toward pericardium and ventrally covered by liver lobe. By electron microscopy we can observe a mucosa layer formed by stratified squamous epithelium and lamina propria with stratum compactum. The epithelium is composed by three types of cells: superficial squamous cells; mucous cells, similar to the globet cells and polyhedric cells. The stratification of this epithelium provides a complete basal layer of proliferation polyhedric cells. The cells in the intermediate region of the epithelium are also...

Repertoire of the acoustic communication of the azure jay Cyanocorax caeruleus (Vieillot) (Aves, Corvidae)
Provedor de dados: 104
Autores: Anjos,Luiz dos; Vielliard,Jacques M. E.
The vocal repertoire of the Azure Jay Cyanocorax caeruleus (Vieillot, 1818) is approached from a quali-quantitative point of view. The qualitative analysis was carried out both in the field and in captivity: the quantitative analysis was made only in captivity. Social acoustic communication in the Azure Jay is achieved through the use of two types of call: basic and intermediate calls. Fourteen basic calls are identified and presented through sonograms: the sotto voce song (courtship call) is related only to courtship and the social call is interpreted as the song in the Azure Jay. The intermediate calls are recombinations of the basic calls uttered during an alteration in motivation level. Examples of them are presented through sonograms of vocalizations...

Several families were added in the past in order to constitute the Xanthidae, but the boundaries between Xanthidae, Parthenopidae and Goneplacidae were diluted, and the classification of some genera doubtful. By this reason was made the analysis of a typical genus of each subfamily occurring in Brazil. 50 characters were selected and coded as (0) for absence and (1) for presence. The data matrix was analysed by computer programs NTSYS and NMIX. The phenetic analysis shows the Xanthidae as a good family, but the cladistic one (Wagner tree) split them in four families: Carpiliidae, Xanthidae (with the subfamilies Menippinae, Platyxanthinae, Xanthinae and Eucratopsinae), Eriphiidae and Pilumnidae (with the subfamilies Trapeziinae and Pilumninae)....

Preliminary checklist of the herpetofauna of the upper Rio Urucu, Amazonas, Brazil
Provedor de dados: 104
Autores: Gascon,Claude; Pereira,Ocírio de Souza.
Thirty-three species of anuran amphibians and 22 species of reptiles were found in 9 days and nights of sampling in an unexplored region of Central Amazon. The community is characterized by typical lowland Amazonian species. The relatively short sampling time and high number of species caught indicates that this region probably has very high species richness.

Variação morfométrica e demográfica em Phaleria testacea Say (Coleoptera, Tenebrionidae) de duas praias do Rio de Janeiro
Provedor de dados: 104
Autores: Almeida,M.D. de; Caldas,A; Almeida,J.R. de.
The species Phaleria testacea Say, 1824 (Coleoptera, Tenebrionidae) varies a lot in size, and its populations along the coast of Brazil, where it lives buried in sandy beaches, have temporal and geographical variation in density. In order to find out which factors were contributing to these variations, we sampled populations from three different areas in Rio de Janeiro, during summer and winter. Simultaneously, we made an analysis of the different substracts where the individuals were found, including their total fresh weight. The results show a significant difference in size of individuals between and within populations, when summer and winter were compared. There is also a positive association between the population density of P. testacea and the amount...

Estádios evolutivos de tripanossomas de Hipostomus punctatus Valenciennes (Osteichthyes, Loricariidae) em infecção natural de Batracobdella gemmata Blanchard (Hirudinea, Glossiphoniidae)
Provedor de dados: 104
Autores: D'Agosto,Marta; Serra-Freire,Nicolau Maués da.
Seventeen leeches obtained from armoured catfish (Hypostomus punclatus Valenciennes, 1840) infected with Trypanosoma spp. were examined. It was observed the presence of tripomastigotes, epimastigotes and amastigotes forms as well as dividing forms in the proboscis and in the stomach, different from the ones found in the vertebrate host as regards the morfometric features and developing forms. The examination of the contents of rectum did not show tripanosomes. These facts seem to demonstrate that Batracobdella gemmata (Blanchard, 1900) is an invertebrate host of trypanosomes and the transmission is done by means of inoculation.

The objective of this study was to determine the size and composition of a group of wild Callithrix jacchus Erxleben, 1777, a small neotropical primate from the North East Brazil. The study was carried out in Dois Irmãos Forest, Recife, Pernambuco, Brazil, in an area of 6ha where this social group of marmosets had its home range. A graded transects system was cut to provide the access and moving during the observation period. To provide an individual identification for the members of the marmosets group and to achieve the objective of this study, two captures were made, with a six month interval between them in a 50x50m² area at the nuclear range of the group's area. The animals were realeased after a maximum period of 24h after traping. We made, during...

The food cycle and geographical variation of Dysdercus diet were studied as strategy elements of trophic resources exploitation. The species used were D. fulvoniger, D. maurus, D. mendesi and D. ruficollis. A random sampling method was adopted at two regular sampling areas (Vassouras and Itaguaí, Rio de Janeiro, Brazil). The places sampled only once were selected based on the potential migration of Dydercus. Various transects were determined, with 99 places; these transects involved six morpho-climatic-phytogeographical domains: Atlantic Tropical, Cerrado, Caatinga, Amazonic Equatorial, Pantanal and "Planalto das Araucárias". The food cycle of Dysdercus at Vassouras is based on the exploitation of reproductive structures (flowerand fruit) of some...

Provedor de dados: 104
Autores: Valenti,Wagner Cotroni; Mello,Jeanette de Toledo Cardoso de; Castagnolli,Newton.
In this article the length growth curves of Macrobrachium rosenbergii (De Man, 1879) held in different population densities were analysed. Postlarvae prawns were stocked into five 0,02 ha earthen ponds at densities of 4, 8, 12, 16 and 20 ind./m² during six months. Forthnightly, the mean total length of animals from each pond were obtained by means of random samples. For each population the length growth curves and the instantaneous growth rate expressions were determined. The growth rate and the asymptotic maximum length decreased with the stocking density raised. This effect is greater when the density ranges in low levels. The growth decrease can be due to intraspecific competition for life resources and to negative interactions between individuals, as...

Longevity and survival of the predator Podisus connexivus (Hemiptera: Pentatomidae) were studied in three alternative preys: T1 - Bombyx mori (Lepidoptera, Bombycidae) catterpilars; T2 - Musca domestica (Diptera, Muscidae) larva and T3 - Tenebrio molitor (Coleoptera, Tenebrionidae) larva. Longevity and survival were: 22,1±0,6 days and 54,3±5,3%; 25,2±1,3 days and 56,0±4,9% and 22,0±0,8 days and 34,6±8,6%, for treatments T1, T2 and T3, respectively. Comparing to other researches, a lower survival was found. This is probably because a F2 generation from field material, was used. Since the insect was not well adapted to the laboratory conditions this could have led to lower survival.

Rock paintings of mammals have been studied in five of the 243 localities contained within the 270,000 km² Archeological Region of Central, Bahia. From features of external morphology, it was possible to recognize 11 mammals represented in the paintings: for five, to attribute the species; another five, the genera; and, for one, merely the family. This study aims to underline the importance of prehistoric man's contribution, by way of these rock paintings, to our knowledge of the mammals depicted, both taxonomically and in terms of their distribution within the bounds of the Project in the State of Bahia.

Autores: Aranha,José Marcelo R.; Caramaschi,Érica P.; Caramaschi,Ulisses.
Patterns of spatial occupation, feeding, and reproductive period of two species, Corydoras aeneus and Corydoras gr. carlae (Siluroidei, Callichthyidae), coexistents in the Alambari River (Botucatu, São Paulo), were studied. High diet overlap, partial spatial segregation, and well differentiated reproductive strategies were verified. These findings do not permit to evidence the occurrence of competitive interactions between the analysed species.

Studies of the cymothoid isopod Livoneca symmetricaVan Name, 1925, showed that this species has characters that preclude its inclusion in LivonecaLeach, 1818, or in any other known genus. The species is redescribed on the basis of male and female specimens from the mouth cavities of Amazonian piranhas (Serrasalmus spilopleura(Kner) and S. elongatusKner) and Vanameagen. nov. is proposed for it. The new genus is defined as having: a cephalon that is not immersed in pereonite 1; mandibles that are "foot-shaped" and without incisors, pereopods that are long and unequal in size and shape; a pleon that is not immersed in the pereon; and a pleotelson that is inflated anteriorly and medially.

A duração do período de desenvolvimento de cada estágio é apresentada para larvas criadas no laboratório, sob diferentes condições de dieta, temperatura e luminosidade. As larvas de T. h. haemorrhoidalis,criadas com dieta de ração, completam seu desenvolvimento, apesar de demorarem mais para atingir o estágio adulto. A luminosidade não teve influência no tempo de desenvolvimento das larvas alimentadas com presas, ao contrário das alimentadas com ração. A baixa temperatura influenciou o desenvolvimento das larvas, independentemente da dieta, prolongando o período de desenvolvimento.

Avaliaram-se os atributos morfológico, agronômicos e nutricionais em quatorze introduções de Aráceas comestíveis em Manaus-AM, nos anos de 1983 e 1984. Em geral os acessos de inhames (Colocasia sp.) apresentaram porte baixo, com folhas de tamanho médio ou pequeno, com rizomas secundários com maior valor para proteína, destacando-se 02/79 como o mais produtivo. Nas taiobas (Xanthosoma sp.) o porte variou muito entre os acessos e a produção total de rizomas o maior rendimento se deve ao rizoma principal onde se concentra também o maior valor nutricional.

Autores: COLLART,Olga O.; ENRICONI,Adriana.
A ecologia do camarão Palaemonetes carteri Gordon, 1935 (Decapoda: Palaemonidae) foi estudada através de coletas mensais, realizadas de janeiro 1989 até maio 1990, na região de Manaus. P. carteri vive na liteira submersa dos igarapés de terra firme em áreas baixas inundadas periodicamente pelas enchentes dos rios. A estratégia de reprodução e a dinâmica da razão sexual foram estudados na base dos 4,441 indivíduos coletados. P. carteri mostrou um dimorfismo sexual do comprimento, as fêmeas sendo maiores que os machos. O período de reprodução foi restrito a enchente e a cheia das águas.

EFEITO DA VELOCIDADE DE SECAGEM SOBRE A EMERGÊNCIA E VIGOR DE SEMENTES DE PUPUNHA (Bactris gasipaes Kunth)
Provedor de dados: 36
Autores: FERREIRA,Sidney Alberto do N.; SANTOS,Lenoir Alves dos.
As sementes de pupunha perdem rapidamente a viabilidade quando sua umidade é reduzida, dificultando o seu transporte e armazenamento. Para determinar o efeito da velocidade de secagem, as sementes de pupunha foram submetidas às seguintes condições: a) meio ambiente de laboratório; b) dessecador com sílical gel na proporção de 1:1 (por peso); c) dessecador com silica gel na proporção de 2:1. A cada dois dias, uma amostra de cada ambiente foi utilizada para testes de emergência e determinação da umidade. Conclui-se que: a) a viabilidade e o vigor das sementes de pupunha são dependentes da interação de sua umidade com a velocidade de secagem; b) a emergência e o vigor das sementes são afetados por pequenas reduções na sua umidade, além da velocidade com que...

Autores: FIM,Jorge D. I.; HARDY,Elsa R.
Os organismos zooplanctônicos desempenham um importante papel na alimentação de larvas e pós-larvas de peixes, tanto na natureza, como em cativeiro em tanques de piscicultura. No aspecto do cultivo de zooplâncton cm massa, somente conhecendo-se os valores de alguns parâmetros importantes do ciclo de vida de um único indivíduo, em situações diversas, é que se pode avaliar se este estará respondendo de maneira adequada, ou não, a determinado tratamento aplicado. O trabalho mostra uma adaptação de mamadeiras plásticas comerciais para a utilização no estudo individualizado de microcrustáceos zooplanctônicos (cladóceros), em laboratório (aquários), viveiros de piscicultura, ou ambientes naturais (lagos e igarapés).

Esses resultados (ainda que preliminares) revelam uma heterogeneidade química em Paepalanthus, em comparação a outros gêneros de Eriocaulaceae.

RECRUITMENT PATTERNS OF SESSILE INVERTEBRATES ONTO FOULING PLATES IN THE BAY OF SANTA MARTA, COLOMBIAN CARIBBEAN
Provedor de dados: 50
Autores: García,Camilo B.; Salzwedel,Horst.
Recruitment of sessile invertebrates onto fouling plates immersed for consecutive two-week periods during one year was found to correlate with the local climatic regime. For selected species it was found that they recruited at significantly higher levels in certain local climatic periods, but that these periods are not necessarily the same for the different species. A conceptual model is presented in which the recruitment process is divided in a pre-settlement and a post-settlement phase. The model attempts to predict under which combination of global circumstances periods of increased recruitment are to be expected. Application of the model to the data at hand highlights where the research needs for the future are.

Las concentraciones de Cu, Pb, Zn, Fe, Mn y materia volátil fueron determinadas en sedimentos superficiales y testigos, materia en suspensión y el ostión Crassostrea rizophorae en la bahía de Manatí, Cuba. La normalización de los contenidos de metales en sedimentos, respecto a la materia volátil, facilitó la interpretación de los resultados y permitió distinguir la afectación por Cu y Zn en la zona de vertimiento de los residuos de una central azucarera y el poblado de Manatí. La especie analizada, aunque mostró variaciones estacionales a lo largo del período estudiado, no reflejó su utilidad como bioindicadora de contaminación por los metales estudiados, lo que parece motivado por las condiciones ambientales de la zona.

Avaliaram-se dados fenológicos da videira 'Niagara Rosada' em diferentes regiões do Estado de São Paulo para as seguintes épocas de poda: 15/7; 1/8; 15/8 e 1/9, durante os anos agrícolas de 1989/90 e 1990/91, com o objetivo de avaliar o comportamento fenológico e as necessidades térmicas da cultura. A duração das fases fenológicas variou em função do local e da época de poda. O ciclo total durou de 116 dias para a época de poda 1º/9, em Tietê e Mococa, até 199 dias para a poda de 15/7 em São Roque. A temperatura-base para a fase brotação-maturação foi de 12°C e a necessidade térmica (graus-dia) média, de 1.330, variando de 1.248 para Jundiaí a 1.386 para São Roque. A data de poda não influenciou o valor da necessidade térmica num mesmo local.

Autores: Reichardt,Klaus; Bacchi,Osny Oliveira Santos; Villagra,Maria Mercedes.
Com dados obtidos em perfis de terra roxa estruturada do município de Piracicaba (SP), é mostrada a dificuldade da estimativa de fluxos de água no solo, utilizando o modelo de Darcy-Buckingham. O experimento trata do estabelecimento de balanços hídricos em 25 parcelas de 5 x 5 m, alinhadas ao longo de uma transeção de 125 m. O componente drenagem profunda do balanço hídrico é estimado mediante medidas de umidade do solo (teta, cm³/cm³), feitas com sonda de nêutrons, e de potencial total da água do solo H (cm H2O) obtidas com tensiômetros. O trabalho mostra a grande dificuldade da estimativa de fluxos de drenagem q (mm/dia), a qual está relacionada: (1) à exponencialidade da relação entre a condutividade hidráulica do solo k (mm/dia) e a umidade do solo ou...

Avaliou-se, em Campinas (SP), o efeito da irrigação por aspersão e da densidade de semeadura na temperatura média do ar e na duração do período de molhamento (DPM), e sua influência em helmintosporiose e oídio na cultura do trigo, em experimentos ao nível de campo durante os invernos de 1990 e 1991 respectivamente. Os resultados foram submetidos a análises estatísticas: de diferença de dados pareados (microclima) e de intervalos de confiança (taxa de crescimento das moléstias). As áreas com maior densidade de plantas e irrigadas mostraram a seguinte tendência: as temperaturas médias foram mais baixas, 0,7°C, e a DPM, com maior duração, 45 minutos. Com relação às taxas de crescimento, notou-se que foram influenciadas positivamente pela irrigação e pela...

Autores: Camargo,Marcelo Bento Paes de; Pedro Júnior,Mário José; Alfonsi,Rogério Remo; Ortolani,Altino Aldo; Brunini,Orivaldo.
Avaliou-se modelo de "distribuição de valores extremos" (Gumbel) para dados de temperaturas mínimas absolutas mensais (maio a setembro) e anual e incidência de geadas, para séries de trinta anos referentes a vinte localidades paulistas. Os parâmetros da função de densidade de probabilidade da distribuição foram estimados para todas as localidades e períodos analisados. O modelo mostrou bom ajuste entre as freqüências estimadas e as observadas. Foram identificadas e quantificadas as áreas com maior risco de ocorrência de temperaturas baixas em nível mensal e anual. As maiores probabilidades de ocorrência de baixas temperaturas foram observadas em junho-agosto, com valores entre 60 e 95% para as regiões serranas e sudoeste do Estado.

Provedor de dados: 53
Autores: Felício,João Carlos; Camargo,Carlos Eduardo de Oliveira; Pedro Júnior,Mário José.
Estudou-se, durante o período 1985-91, o comportamento de 21 cultivares de trigo no Vale do Paranapanema, Sudoeste paulista, avaliando-se a produtividade de grãos, as reações aos agentes causais de ferrugem-da-folha, da helmintosporiose e do oídio, e às condições climáticas da região. A precipitação pluvial foi dividida em decêndios dentro de cada mês (março a outubro). O excesso de umidade no segundo decêndio de junho de 1987 favoreceu a ocorrência das moléstias estudadas. Os cultivares OCEPAR 14, IAC 227, IAPAR 17, IAC 60, IAC 28, IAC 18, IAC 17 e IAC 21 apresentaram produtividade média superior à do 'BH 1146' (testemunha), e os cultivares OCEPAR 7 e Alondra foram os menos produtivos.

Efeito da falta de normalidade em testes de homogeneidade das variâncias
Provedor de dados: 53
Autores: Conagin,Armando; Nagai,Violeta; Igue,Toshio; Ambrósio,.
Em experimentos de campo, é freqüente o aparecimento de tratamentos com variâncias heterogêneas, decorrente, muitas vezes, do tipo dos tratamentos que estão sendo estudados. Os dados desses ensaios são usualmente submetidos à análise da variância, cuja aplicação correta exige que as observações tenham uma variância comum. A falta de homogeneidade pode surgir, também, segundo alguns autores, quando, os erros experimentais têm distribuição assimétrica. A falta de normalidade dos erros tem sido considerada como um fator que pode distorcer os resultados de testes empregados para verificar a hipótese de igualdade de médias ou das variâncias. Para avaliar a influência da falta de normalidade sobre os testes de Bartlett, Cochran e Hartley (Fmáx), com e sem...

Provedor de dados: 53
Autores: Cristofani,Mariângela; Mendes,Beatriz Januzzi; Tulmann Neto,Augusto; Ando,Akihiko.
Estudou-se a viabilidade de protoplastos de laranja 'Pêra' (Citrus sinensis Osbeck), submetidos a diferentes doses de radiação gama, com a finalidade de determinar a dose letal (DL) 50 - dose que causa 50% de letalidade. Empregou-se a análise por fluorescência, utilizando-se o corante diacetato de fluoresceína (DAF): suas diluições testadas - 1:50; 1:100 e 1:150 - não mostraram diferenças significativas entre si, tendo sido possível o uso da maior diluição para a determinação da viabilidade dos protoplastos. A viabilidade mostrou-se inversamente proporcional às doses de radiação gama e a DL 50 foi cerca de 41 Gy. Os protoplastos não irradiados apresentaram até 84% de viabilidade, quando esta foi estudada logo após o isolamento daqueles.

Em dezesseis experimentos de campo desenvolvidos com o cultivar IAC 20 em diferentes regiões paulistas, de 1984 a 1987, estudou-se a competição de adubos nitrogenados na cultura algodoeira. Sulfato de amônio e uréia foram aplicados em cobertura incorporada nas doses de 0, 25, 50, 75 e 100 kg/ha de N, em esquema fatorial, com quatro repetições distribuídas em blocos ao acaso. Em dois anos agrícolas, testou-se a não-incorporação da cobertura, na dose de 75 kg/ha de N, com o auxílio de tratamentos extras. Nos solos em pousio, ou seja, que estiveram anteriormente cobertos com pastagens antigas ou com leguminosa, ocorreram altas produtividades associadas às baixas respostas das plantas ao N mineral aplicado. O aumento da produtividade, de certa forma,...

Seletividade de trifluralin incorporado ao solo para batata-doce
Provedor de dados: 53
Autores: Monteiro,Domingos Antonio; Peressim,Valdemir Antonio; Lorenzi,José Osmar; Perecin,Dilermando.
No Estado de São Paulo, a batata-doce é cultivada em escala comercial como produto hortigranjeiro. Em vista das dificuldades para o controle manual e o mecanizado das plantas infestantes da cultura, há grande interesse pelo método químico desse controle. Com essa finalidade, tanto pelo baixo custo relativo como pelas facilidades técnicas de utilização, o trifluralin desperta a atenção dos agricultores. Para avaliar a seletividade do herbicida para essa cultura, foi realizado um experimento em vasos, com doses crescentes do produto, nas seguintes concentrações: 0,00; 0,11; 0,22; 0,44; 0,88; 1,76 e 3,52 mg.kg-1 de i.a. em peso.

Autores: Igue,Toshio; Conagin,Armando; Nagai,Violeta; Ambrósio,Luís A.
Para verificar se a pequena influência da heterogeneidade das variâncias, observada em trabalho anterior, sobre os testes de Bonferroni, "t" e Tukey se devia ao fato de ter sido utilizado o erro médio que corresponde ao quadrado médio da interação tratamentos x blocos (Q.M. trat x bloco), os autores estudaram o comportamento do teste "t" com o uso de três tipos de erro: Q.M. trat x bloco, erro do contraste específico e erro ponderado dos contrastes. Foram simulados 200 experimentos, em grupos de 50, para cada uma das 56 combinações de quatro coeficientes de variação, dois efeitos de tratamentos e sete grupos de heterogeneidade, totalizando 11.200 experimentos.

Autores: Conagin,Armando; Nagai,Violeta; Igue,Toshio.
A análise clássica de grupos de experimentos constitui um dos problemas mais sérios com que se defrontam os estatísticos, fitotecnistas e melhoristas de plantas. Vários métodos têm sido propostos para contornar os problemas que podem surgir na análise conjunta e que tomam, muitas vezes, complicada a comparação entre médias. O desenvolvido por Fisher permite combinar a probabilidade dos resultados de testes de comparação de médias ou testes de contrastes, independentemente, entre outros fatores, do tipo de teste e de experimento, do número de repetições, da existência de erros experimentais diferentes ou de interações. Neste trabalho, procurou-se avaliar a importância da precisão experimental, da média geral do experimento e da amplitude das diferenças...

No Estado de São Paulo, além das culturas comerciais que destinam sua produção às indústrias de transformação ou aos mercados hortifrutigranjeiros, a mandioca (Manihot esculenta Crantz) é muito difundida em culturas denominadas de "fundo de quintal". Nesse caso, muitas variedades são cultivadas e utilizadas precipuamente para consumo doméstico, tendo o presente trabalho por objetivo avaliar a amplitude de variação do seu teor de ácido cianídrico (HCN). Foram analisadas raízes de 206 variedades originárias de uma coleta sistemática realizada em 126 municípios paulistas, utilizando-se o método de Liebig, com maceração por 24 horas. Os resultados mostraram que a amplitude máxima de variação do ácido cianídrico foi de 16 a 482 mg.kg-1 na polpa crua das raízes....

Entre el spray y la pared. Graffiti : liminalidad en el espacio urbano
Provedor de dados: 122
Autores: Ensignia, Marco A.
Desde hace algo más de dos años a la fecha, se viene desarrollando en un sector de la ciudad de Quito, un hecho significativo para la aprehensón de la dinámica de la vida social urbana: la apropiación de los muros citadinos mediante pintas graffitti. La bibliografía sobre el graffitti no es abundante, y no profundiza en una interpretación relacional entre el graffitti y los sujetos de la experiencia. El cuestionamiento, entonces, que cruza este trabajo y que informa la especifidad de los que de él se derivan es el ¿por qué el hecho de desarrollo en Quito y en el tiempo?.

Protestantismo: formas de creencia. Estudio de caso de la presencia protestante en Chimborazo, Ecuador
Provedor de dados: 122
Autores: Laporta Velásquez, Héctor.
El estudio de lo religioso a través del tiempo ha sido abordado partiendo de diversas entradas y disciplinas, sin embargo persisten algunas dificultades y problemas. Por un lado, al no percibir la dimensión subjetiva de la religión, la creencia ha sido vista como un armazón elemental de signos y significados que explican totalidades de lo real y envuelven a la persona particular dejando de lado la certeza religiosa sumergida en el correr de lo cotidiano, lo que ella significa en la experiencia práctica de los sujetos.

Durante algunos años he sido testigo de los diarios sacrificios y alegrías de los campesinos en su esfuerzo por asegurar la vida de sus familiares.

La vasta teorización acerca de las economías campesinas profundiza en algunos aspectos, pero expresa parcialmente la dinámica y complejidad de estas formas de producción. ¿Cómo integrar una perspectiva histórica en el análisis de las unidades productivas campesinas? ¿Cómo aprehender la complejidad de sus intercambios?, ¿Cómo analizar unas prácticas productivas en que se manifiestan dimensiones familiares, sociales y rituales?

Lo novedoso de esta investigación no radica en haber tomado en cuenta la perspectiva del análisis medioambiente/antropologia, perspectiva que ha sido abordada con mucho acierto por las diversas corrientes teóricas en la antropologia ecológica, sino que el aporte y el esfuerzo que representa este trabajo es la valoración del tratamiento ecopolítico del espacio, articulado por los conceptos de "tácticas y estrategias" como...

Esta tesis busca desarrollar una aproximación teórica al estudio del derecho consuetudinario en los pueblos indígenas amazónicos. Aún cuando la naturaleza profundamente heterogénea de los distintos pueblos amazónicos, es una dificultad, es posible esbozar algunos elementos teóricos que, incorporando las " diferencias entre las distintas etnias, sirvan como instrumento de análisis de la realidad del derecho indigena amazónico. Este estudio se apoya en la hipótesis de que toda sociedad tiene una organización social propia y que dicha organización social requiere de un mecanismo adecuado de resolución de conflictos, por tanto, es posible afirmar la existencia del derecho en ellas

Proceso socio-económico sobre la explotación del caucho en la Amazonía ecuatoriana 1850-1920
Provedor de dados: 122
Autores: Vicuña Cabrera, Azucena.
El período del caucho, que en términos generales se extiende entre 1850 y 1914, implicó para los países de la cuenca amazónica grandes cambios en lo que se refiere al peso de la producción de esta región geográfica, y a las diversas formas en que los estados intentaron controlar los ingresos derivados del comercio del caucho. Si bien conocemos a través de diversos trabajos etnohistóricos y etnográficos (Muratorio: 1978; Reeve:1988) que el Ecuador participó de estos cambios y dinámicas, poco se sabe acerca de cuál fue el devenir de la economía cauchera en el país . Para otros países contamos con estudios sobre la economía cauchera, más o menos profundos y más o menos englobantes.

Desarrollo sustentable y manejo de bosques naturales en la Amazonía peruana : un estudio económico ambiental del sistema de manejo forestal en fajas en el valle del Palcazu
Provedor de dados: 122
Autores: Elgegren Apuela, Jorge Octavio.
Es obvio que los bosques tropicales tienen valores pertenecientes a la esfera del mercado y valores que escapan a su influencia: por ejemplo, la madera es un producto que tiene (casi siempre) valor de mercado; en cambio, la protección del cauce de un río por parte de la cubierta vegetal no tiene un valor de mercado. Esta asimetría en la asignación de valores implica un sesgo considerable a favor del uso de la tierra hacia fines lucrativos más que de conservación y es una causa fundamental para explicar desde la perspectiva económica el fenómeno de la deforestación y el uso no sustentable de recursos naturales.

Autores: Maman Rodríguez, Ítala de.
En el marco de la estructura político-administrativa del régimen colonial, el cargo de corregidor era uno de sus pilares fundamentales. El estudio de esta institución sin lugar a dudas permitirá entender mejor una parte importante de la trama de relaciones del mundo colonial, muy particularmente en el período 1750-1790, en que la vigencia de esta institución es puesta en tela de juicio. En la historiografía sobre la época colonial, han prevalecido los estudios sobre temas referentes a los centros de política o económica, mientras que zonas periféricas como Audiencia de Quito solo fueron tomadas en parte como tema interés por los investigadores.

Si bien el sistema de áreas protegidas responde a teorías filosóficas y ecológicas internacional y nacionalmente legitimadas, se topan en la práctica con limitaciones provenientes del modelo de desarrollo imperante a nivel mundial y sobre todo de las condiciones económicas sociales y políticas de un país dependiente como es el Ecuador. En este contexto, en el momento actual, este sistema enfrenta un sinnúmero de presiones de todo tipo, por parte de diversos sectores sociales involucrados en él, que ha llevado a que las áreas protegidas, se conviertan en espacios de alta conflictividad ecológica, económica, social y política.

Estos símbolos, quiero mostrarlo en el estudio, llegan a constituirse como tales, entre otras cosas, en la confrontación con la idea que la sociedad mayor, concretamente los hacendados, tiene sobre los dos elementos seleccionados.

Lo que es más grave, plantear que nuestra producción y nuestros productos acaban en la mera representación escrita supone aislarse artificialmente del lenguaje y las acciones de la vida cotidiana.

La identidad es una pol??tica y no una herencia.
Provedor de dados: 122
Autores: Echeverr??a Almeida, Jos??.
La identidad vista desde la cultura y en referencia al estado, como un proceso hist??rico, es un fen??meno complejo que requiere una gran acuciosidad de parte del antrop??logo para poder observar los procesos de identidad. En la compleja interacci??n humana  la identidad se va modelando de acuerdo a los requerimientos micro y macro de una realidad determinada. La identidad es una expresi??n y una ratificaci??n continuas que se materializan en la manera de pensar y autodeterminarse, por eso, la identidad se construye siempre con respecto a algo, en la interdependencia entre grupos.

Parteras, entre brujas y doctores : juegos de poder ambiguos entre agentes de los sistemas de salud formal e informal en la sierra ecuatoriana
Provedor de dados: 122
Autores: Goblet Malve, Veronique.
Este ensayo analiza la articulación de los sistemas de salud formal e informal en el campo político. Se ve los juegos de poder entre los diferentes agentes que entran en competición para la atención del embarazo, parto y posparto. Son juegos recíprocos, pero asimétricos, que tratan de evitar el choque frontal. Las parteras, en algunas circunstancias, sufren de "violencia simbólica" por parte de los doctores, pero, en otras, luchan y resisten mediante tácticas sutiles, ambiguas e invisibles que les permiten llegar de alguna manera a reapropiarse del orden y espacio dominante. Las apropiaciones, que se hacen tanto por parte de las parteras como de los doctores, son materiales y simbólicas, selectivas y funcionales. Para atraer más clientela y valorizar su...

La reserva faunística Cuyabeno : un espacio de conflicto y constitución de actores
Provedor de dados: 122
Autores: Garcés Dávila, Alicia.
Si bien el sistema de áreas protegidas responde a teorías filosóficas y ecológicas internacional y nacionalmente legitimadas, se topan en la práctica con limitaciones provenientes del modelo de desarrollo imperante a nivel mundial y sobre todo de las condiciones económicas sociales y políticas de un país dependiente como es el Ecuador. En este contexto, en el momento actual, este sistema enfrenta un sinnúmero de presiones de todo tipo, por parte de diversos sectores sociales involucrados en él, que ha llevado a que las áreas protegidas, se conviertan en espacios de alta conflictividad ecológica, económica, social y política.

During 20 months of the 1987-1990 period, lung tissue samples from 351 calves were obtained at a slaughterhouse. These calves were from counties nearby Porto Alegre. The direct and indirect fluorescent antibody tests (FAT) using polyclonal and monoclonal antibody conjugates were performed on frozen lung sections. Eighteen (5.13%) of the calf lung samples were positive for the Bovine Respiratory Syncytial Virus (BRSV). The BRSV was isolated from FAT positive samples.

Procurou-se verificar as possíveis alterações no quadro hematológico de doze cães, sem raça definida, com idade de 1 à 7 anos, de ambos os sexos e clinicamente sadios que sofreram ostetomia diafisária da tíbia direita e esquerda acompanhada de terapia "laser" (AsGa) nas regiões operadas do membro esquerdo. As aplicações foram diárias com dosimetria de 5 joules/cm² de forma pontual e em varredura. Foram feitas aplicações de "laser" do 1° ao 10° dia e do 31° ao 40° dia do pós-operatório. As colheitas de sangue para hemograma foram realizadas no pré-operatório e no 1°, 5°, 10°, 31°, 35° e 40° dias do pós-operatório, imediatamente antes da aplicação "laser". Os resultados encontrados não apresentaram alterações significativas, comparativamente com as amostras...

Autores: Unk,Dionisio; Costa,Ervandil Corrêa; Miotti,Jorge Humberto Vasquez; Balardin,Clarice Rubin.
Visando o controle do ataque do caruncho, Sitophilus oryzae (L, 1763) em trigo armazenado, aplicou-se, em mistura direta com os grãos, 7,5; 10; 15 e 20g i.a. de Diclorvos (DDVP-500) e 12g i.a de Diclorvos (DDVP-1000) por tonelada. Utilizando-se um calador retirou-se 0,5 litros de grãos por parcela, em cinco ocasiões, sendo uma antes e quatro após a aplicação dos produtos, para avaliação do número de insetos vivos. Todas as doses e produtos controlaram eficientemente o caruncho no trigo armazenado, com exceção da dose de 7,5g i.a./t de grãos, de Diclorvos, que não atingiu 90% de controle em todas as datas e, pêlos níveis de infestação ocorrentes durante o teste não deve ser recomendada.

SOIL TEMPERATURE MODIFICATIONS CAUSED BY SOLARIZATION IN NURSERIES
Provedor de dados: 65
Autores: Streck,Nereu Augusto; Schneider,Flavio Miguel; Buriol,Galileo Adeli.
Solarization effects on soil temperature were evaluated during the autumn. The increase in soil temperature caused by the use of transparent polyethylene (PE) low tunnels over solarized nurseries, in subtropical central region of the Rio Grande do Sul state, Brazil, was also quantified.

SEROLOGICAL SCREENING FOR INFECTIOUS CATTLE DISEASES: II. ASSOCIATION BETWEEN PREVALENCE AND LEVEL OF ELISA RESPONSE
Provedor de dados: 65
Autores: Rojas,José Alfonso Barajas-; Riemann,Hans; Franti,Charles.
A herd of cattle (Holstein-Zebu crosses) was screened every two months by ELISA during a period of two years for IgG antibodies against 19 infectious disease agents. Two hundred and ninety five sera were collected from 157 young animals (0-4 months of age), 1037 sera from 292 developing animals (4-36 months of age) and 1468 sera from 259 producing animals (&gt; 36 months of age). The results indicate that the difference in ELISA between positive and negative tests is associated with the overall prevalence of positive tests. When the prevalence of positive tests is low the difference between positive and negative tests is greater than when the prevalence is intermediate or high. This means that ELISA, presumably other serological tests for IgG antibodies,...

Provedor de dados: 65
Autores: Happke,Klaus; Rosa,Monica do Nascimento; Kubota,Ernesto Hashime; Terra,Nelcindo Nascimento.
Três partidas de mortadela foram elaboradas segundo uma mesma formulação, diferenciando-se porém quanto ao antioxidante utilizado. Uma das partidas recebeu 0,25% de Fixador A-80 (ácido ascórbico), a outra 3,35% de destilado de refinaria de óleo de soja (tocoferóis) e a terceira, o controle, não recebeu a adição de antioxidante. As peças de mortadela foram mantidas em temperatura ambiente (8 a 20ºC) e analisadas semanalmente visando-se o acompanhamento da oxidação lipídica. O destilado do refino do óleo de soja demonstrou propriedades antioxidantes similares às do Fixador A-80. O baixo custo deste destilado irá refletir-se na redução do custo de fabricação dos embutidos curados.

MARKOV CHAIN MODELING OF ENDEMIC CATTLE DISEASES IN THE TROPICS OF MEXICO
Provedor de dados: 65
Autores: Rojas,José Alfonso Barajas; Riemann,Hans; Franti,Charles.
Endemic diseases measured by prevalence of IgG antibodies by ELISA all showed remarkably stable overall prevalences over a study period of 3 years. This however does not mean that incidence is low or absent. Observed transition from the state of being positive for a disease to the state of being negative and vice versa suggested fairly high incidence rates (and rates of waning antibodies) for all 19 disease agents tested for. In spite of this dynamic situation Markov Chain simulations indicate that a steady prevalence is reached in a fairly short time. Markov Chain simulations may also be useful in elucidating seasonal changes in prevalence.

Através do presente trabalho procurou-se determinar a idade ideal para a vacinação de potros contra o herpesvírus eqüino tipo 1 (HVE-1) direcionada para o tipo de criação regional, uma vez que os protocolos de vacinação comumente utilizados são originários de outros países. Para tal, utilizou-se soro de 61 potros filhos de éguas vacinadas contra o HVE-1. A recomendação da vacinação de potros, baseados nos resultados, situou-se por volta dos dois meses de idade, pois nesse período grande parte da população estudada possuía títulos de anticorpos considerados baixos e provavelmente insuficientes frente a um possível desafio de campo.

Provedor de dados: 65
Autores: Pinto,José Eduardo Brasil Pereira; Pinto,César Augusto Brasil Pereira.
Tubérculos de três novos clones de batata e da cv. "Red Pontiac" foram armazenados sob temperaturas de 1ºC, 8ºC e 20ºC. Os tubérculos armazenados sob condições de baixas temperaturas foram mantidos por 30, 60, 90 ou 180 dias e posteriormente recondicionados por 10 dias a 20ºC. Nenhuma diferença significativa foi detectada entre os clones sob as condições estudadas. O armazenamento a 1ºC estimulou o acúmulo de açúcares redutores e sacarose, principalmente nas primeiras semanas. O recondicionamento a 20ºC reduziu estas concentrações.

Provedor de dados: 65
Autores: Pianta,Celso.
Diarréia neonatal em bovinos é um quadro complexo, normalmente responsável por altas taxas de morbidade e mortalidade. Os prejuízos são observados não somente nos gastos com a medicação, mas também na perda do animal em caso de morte e na redução do desenvolvimento e do desempenho do futuro animal adulto, comprometendo os índices de ganho de peso ou produção leiteira. A etiologia múltipla da enfermidade envolve a interação de diversas variáveis dos agentes, hospedeiro e meio ambiente. Nesta revisão são abordados os aspectos clínicos da colibacilose sanitário, a prevenção e o tratamento são também abordados.

A STUDY OF ASSOCIATION BETWEEN ELISA RESPONSE TO INFECTIOUS DISEASE AGENTS AND CALVING INTERVAL IN CATTLE IN THE TROPICS OF MÉXICO
Provedor de dados: 65
Autores: Barajas-Rojas,José Alfonso; Riemann,Hans; Franti,Charles.
Forty eight cows of Holstein-Zebu crosses with at least one completed pregnancy were tested for antibodies to 20 disease agents. The testing was performed within one month (average two weeks) after calving when the IgG level constantly reaches its lowest value during the cows reproductive cycle. The results indicate that increasing levels of IgG against Leptospira interrogans serovar hardjo and Mycobacterium paratuberculosis may be associated with an increased calving interval. Increase in calving intervals could not be explained by age of cows or their genotypic characteristics.

A herd of Cattle (Holstein-Zebu crosses) was screened bimonthly for two years by ELISA for IgG antibodies to infectious disease agents. The herd was composed of 3 age groups: Young animals ( &lt; 4 months of age), developing animals (4-36 months of age) and producing animals ( &amp;gt; 36 months of age). Ali young animals received colostrum within two hours after birth. The overall consistency of ELISA results, i. e agreement between two consecutive tests was about the same for the three age groups and was lowest for infections of intermediate prevalence (40-50%). The interpretation of changes in seroprevalence is most straight forward for young animals. Young animals positive at their first test reflect the immune status of their mothers while young...

O trigo é um dos cereais cultivados pelo homem que sempre mereceu destaque, pois apresenta grande importância econômica e na alimentação humana. Em termos de produção no Brasil, a cultura do trigo tem amplas possibilidades de expansão, tanto nas áreas tradicionais de cultivo quanto na região central do País, dependendo apenas da disposição do governo em apostar na busca da auto-suficiência. Entretanto, a produção nacional é ainda insuficiente para atender às necessidades de consumo anual, que atualmente são de 6,8 milhões de toneladas. Hoje os estados do Rio Grande do Sul, Santa Catarina e Sul do Paraná detêm cerca de 50% da área cultivada e 45% da produção nacional, enquanto o norte do Paraná, Mato Grosso do Sul e São Paulo detêm cerca de 47% da área e...

EFEITOS DA DISPONIBILIDADE DE SOMBRA DURANTE O VERÃO SOBRE A PRODUÇÃO DE LEITE DE VACAS DA RAÇA HOLANDÊS
Provedor de dados: 65
Autores: Carvalho,Nelcy Madruga de; Olivo,Clair Jorge; Buriol,Galileo Adeli.
O objetivo do presente trabalho foi o de avaliar o desempenho de vacas da raça Holandês em lactação, submetidas a manejo com e sem disponibilidade de sombra, durante as horas mais quentes do dia, no verão, com relação à produção de leite. Após um período de 55 dias, ficou evidenciada uma clara tendência de menor produção de leite por parte dos animais que não tiveram acesso à sombra, sendo que os de maior produção mostraram-se mais sensíveis às condições desfavoráveis do manejo ao Sol. Com base nos dados obtidos, concluiu-se que se faz necessária a disponibilidade de sombra durante os meses quentes de verão, para as vacas leiteiras em lactação, principalmente para aquelas de mais alto nível de produção.

ANÁLISE DE ESTABILIDADE FENOTÍPICA DE CULTIVARES DE SOJA EM 28 AMBIENTES DO RIO GRANDE DO SUL
Provedor de dados: 65
Autores: Saccol,Ailo Valmir; Storck,Lindolfo.
O presente estudo utilizou os dados de rendimento de 21 cultivares de soja, em 28 ambientes do Rio Grande do Sul, para uma análise de estabilidade pelo modelo bi-segmentado descontínuo (STORCK, 1989), com correções devido a erros nas variáveis. As principais conclusões foram; 1) O método mostrou-se adequado para o estudo da estabilidade fenotípica de cultivares de soja, porque houve uma boa variação ambiental e um bom ajustamento dos dados ao modelo; 2) O grupo de cultivares estudado pode ser classificado em: a) Indesejáveis (Hill, IAS-2, Paraná, Prata, Sel. Foscarin, Louisiana, Hardee, Bienville, Industrial, Santa Rosa, Bossier e Viçoja); b) Adaptáveis tanto aos ambientes inferiores como aos superiores, dentro da região estudada (Pérola, Bragg e Jakson);...

Foram analisadas amostras de lã de várias regiões do velo de borregas pertencentes a duas raças (Ideal e Corriedale) seguindo duas seqüências diferentes para as determinações de porcentagem de cera e suor, cor e pH do suor e coloração da lã. No primeiro método extraiu-se inicialmente a cera e depois o suor (Cera + Suor) e no segundo método a ordem inversa (Suor + Cera). As raças diferenciaram-se quanto à tendência dos valores nas características de cor e porcentagem de suor. Diferenças significativas (P &lt; 0,001) foram observadas na porcentagem de cera, sendo que o método de análise que iniciava pela extração da mesma apresentou valores mais elevados, nas duas raças, para esta característica. A porcentagem de suor foi superior (P &lt; 0,005) para o...

PRODUCTION OF OVOGONIA BY GERMINATIVE EPITHELIUM OF THE OVARY AT SOME MAMMALIA AND BIRDS
Provedor de dados: 65
Autores: Sincai,Mariana; Marcu,Adrian.
The studies were effected on ovaries from sows, cows, bitches, dous and hens. Our investigations revealed the generation of cellular rows of germinative epithelium into the cortex not only during the embrionary period but also in the adult ovary. The histological investigations revealed an intense proliferative process of the germinative epithelium of adult ovary which generated groups of ovogonia under the lamina basalis. From ovogonia developed oocytes and then ovarian follicles. The cause for the proliferation of ovary germinative epithelium could be: the multiple folliculary dehiscences, the premature degeneration of ovarian follicles and formation of the corpus luteum, phenomena that reduce continually the number of embrionary ovogonia.
