Функциональная морфология морских многоклеточных водорослей
Provedor de dados: 13
Autores: Хайлов, К.М.; Празукин, А.В.; Ковардаков, С.А.; Рыгалов, В.Е.
В монографии рассматривается связь внешнего строения водорослей и параметров их биогенного обмена со средой. Изменение морфофункционального комплекса прослежено в онтогенезе на уровне ветвей, целых слоевищ, в совокупностях слоевищ, а также в биокосных системах растение-вода и растение-твердый субстрат. Оцениваются параметры жизненного пространства водорослей на разных уровнях организации, из связь с биомассой и продукцией. Обсуждаются принципы морфофункциональной организации водорослевых фитосистем.

Operações de pré-plantio do toco alto de seringueira.
Provedor de dados: 14
Autores: MORAES, V. H. de F.
A tecnica de parafinagem do caule do toco alto, desenvolvida pela Montebor Agricola Ltda. (Manaus, AM), garantiu, em plantio feito em 1988, uma taxa de pegamento ao redor de 95%, sem gemas brotadas e em plena estacao chuvosa. Mas, na estacao seca subsequente, ocorreram escalduras ao longo do caule, com morte de muitas plantas e atraso no crescimento das sobreviventes, evidenciando a necessidade de caiacao do caule. Essa tecnica, suscitou a expectativa de que seria possivel prescindir-se da brotacao previa das gemas do apice e, com a substituicao do corte antecipado da pivotante pela inducao de rizogenese com auxina, o plantio do toco alto seria liberado dos prazos rigidos apos as operacoes previas ao plantio. Os experimentos descritos tiveram esse objetivo...

O que ha de errado com citricultura baiana?
Provedor de dados: 14
Autores: COELHO, Y. da S.
As referencia aos citros no Estado da Bahia de forma organizada em laranjais remontam o ano de 1540, quando já floresciam plantas nas proximidades de Salvador. Já em 1800 a laranja de "umbigo", mutação da laranja 'Seleta', era também cultivada e amplamente apreciada graças a excelência dos frutos produzidos. A laranja 'Bahia' que teve origem neste Estado significa extraordinária contribuição para a citricultura mundial, pois o seu alto valor comercial representou em vários países onde foi introduzida um forte estimulo ao cultivo de citros. Estados Unidos (Califórnia), Espanha, Austrália e África do Sul são alguns dos países que experimentaram grande avanço na citricultura tendo a laranja 'Bahia' como um dos fatores de desenvolvimento. Os vários fatores se...

Provedor de dados: 14
Autores: LEDO, A. da S.
A gravioleira é uma das mais importantes espécies de planta da família Annonaceae. É originária das Antilhas e dos Vales Peruanos. No Brasil é conhecida também como jaca-de-pobre, jaca-do-pará, coração-de-rainha, araticum manso e araticum gigante. No Estado do Acre, vem sendo cultivada com baixos índices de capitalização e níveis tecnológicos. Entretanto, esta fruteira possui ótimo mercado consumidor, com grandes perspectivas para exportação, por ser uma fruteira regional de excelente sabor e com potencial para industrialização.

Estudo do mulateiro, Calycophyllum spruceanum Benth, em condições de ocorrência natural e em plantios homogêneos.
Provedor de dados: 14
Autores: OLIVEIRA, M. V. N. d'.; MENDES, I. M. da; SILVIERA, G. da S.
O mulateiro é uma das espécies que vêm sendo exploradas por pequenos madeireiros e produtores, de forma extensiva no Estado do Acre. A exploração é feita às margens dos rios e igarapés, onde as árvores são derrubadas, cortados os pranchões e transportados para cidades próximas. Apesar da boa qualidade da madeira, para uso múltiplo, os preços de mercado são muito baixos. É uma espécie pioneira com ocorrência próxima a praias e capoeiras. O trabalho está sendo realizado na Floresta Estadual do Antimari e na Área de Estudos da FUNTAC, no km 67 da BR 317, com os seguintes objetivos a) acompanhar o ciclo fenológico da espécie; b) estudar seu crescimento e características de ocupação em áreas de ocorrência natural; c) estudar o comportamento da espécie em...

O experimento foi conduzido na Fazenda Experimental do Centro de Pesquisa Agroflorestal do Acre - CPAF-Acre, localizada no município de Rio Branco. Foram utilizados inicialmente 20 matrizes e dois reprodutores mestiços da raça An-glo-nubiana, criados em regime semi-intensivo de exploração, tendo como base alimentar pastagens de colonião (Panicum maximum) e brizantão (Brachiaria brizan-tha). O sistema de acasalamento adotado foi o da monta natural a campo, onde o macho permanecia com as fêmeas durante todo o ano. Foram obtidos os índices de prolificidade (1,26%) natalidade (125,2 %); fertilidade ao parto (87,5%); intervalo entre partos (266,2 dias); proporção sexual (50%); mortalidade de 0-6 meses (14,63%); peso ao nascer para machos (2,81 i&lt;g), para...

Exploração de madeira em várzea pelo método tradicional no Paraná Abufari no médio rio Purus.
Provedor de dados: 14
Autores: OLIVEIRA, M. V. N. d'.
Estudou-se a regeneração natural em floresta de várzea na região do paraná Abufari no médio rio Purus, onde houve exploração pelo método tradicional de exploração de várzeas. Foram estudadas áreas exploradas há um, cinco e dez anos, para avaliar, comparativamente, o desenvolvimento da regeneração natural dessas áreas com áreas não perturbadas adjacentes. Para facilitar a análise, as espécies foram divididas em sete grupos: comerciais boiantes, não-comerciais boiantes, comerciais não-boiantes, não-comerciais não-boiantes, invasoras, sub-bosque e exploradas na área de estudo. De um modo geral, a floresta resultante após a exploração apresentou uma regeneração natural mais densa e com uma melhor distribuição das espécies pela área. A entrada de invasoras...

Pragas da gravioleira no estado do Acre: recomendações para seu controle.
Provedor de dados: 14
Autores: LEDO, A. da S.
Um dos entraves para a exploração comercial da gravioleira (Annona muricata L.) no Estado do Acre tem sido o ataque generalizado de pragas, que afetam o crescimento da planta reduzindo a frutificação e diminuindo o valor comercial dos frutos. O grau de incidência e a disseminação dessas pragas são altamente influenciados pelas condições climáticas do trópico úmido. Por meio de coletas de frutos e ramos atacados de gravioleiras, em pequenos pomares do município de Rio Branco, foram identificadas duas pragas: a broca-do-fruto (Cerconota annonela (SEPP, 1830) e a broca-do-tronco (Cratosomus spp.). Tendo em vista o potencial dessa frutífera para a comercialização e industrialização, bem como a escassez de informações técnicas quanto ao controle dessas pragas...

Efeito de níveis de calcário sobre a produção de alfafa (Medicago sativa L.) na região do Submédio São Francisco.
Provedor de dados: 14
Autores: D'OLIVEIRA, L. O. B.
Foi estudado o efeito de calcario em alfafa (medicago sativa L.), cultivar Africana, em Latossolo da regiao do Submedio Sao Francisco. O experimento foi conduzido na Estacao Experimental de Bebedouro, em Petrolina,PE. Os tratamentos consistiram de treze corte e os subtratamentos de quatro niveis de calcario: 0; 1,8; 3,6 e 5,4 t/ha, em um delineamento de blocos ao acaso, em parcelas subdivididas com quatro repeticoes. Os sucessivos cortes mensais provocaram queda de producao. O efeito benefico de um periodo de repouso e mostrado pela maior producao de 1,6 t/ha de materia seca obtida no setimo corte. Em relacao aos niveis de calcario, foi estimada uma equacao quadratica, onde se obteve uma producao maxima de 1,39 t/na de materia seca, correspondente a...

Recomendações para controle da mosca-dos-chifres no Pantanal.
Provedor de dados: 14
Autores: BARROS, A. T. M. de.
A Haematobia irritans chegou ao Pantanal no inicio de 1991. Em abril, ja havia sido reportada em varias propriedades nas sub-regioes da Nhecolandia e Paiaguas, e alcancava tambem os rebanhos proximos as cidades de Corumba e Ladario. Em pouco tempo verificou-se sua distribuicao por toda a planicie e a consequente necessidade de efetuar-se seu controle. O presente artigo objetiva fornecer ao produtor uma orientacao tecnica sobre o controle deste parasito, tendo sido baseado na observacao da mosca em seu primeiro ano de ocorrencia na regiao e na constatacao de infestacoes consideradas como significativamente prejudiciais a producao. De modo geral, recomenda-se a aplicacao de piretroides "pour-on" no inicio (outubro) e final (maio) da epoca chuvosa;...

Introdução e avaliação de cultivares e porta-enxerto de citros em Rio Branco-AC.
Provedor de dados: 14
Autores: RITZINGER, R.; LEDO, A. da S.; RITZINGER, C. H. S. P.; AZEVEDO, F. F. de.
O Brasil apresenta-se como um grande produtor e exportador de suco de frutas cítricas. Esta situação, no entanto, é sustentada pelos Estados do Sul, Sudeste e Nordeste do País, onde se concentram os cultivos e as indústrias de processamento. As regiões Norte e Centro-Oeste pouco participam na oferta de frutas cítricas, sendo que a produção é insuficiente para atender ao consumo interno, (PASSOS, 1990). No Estado do Acre, a citricultura ainda tem pequena expressão econômica, sendo que até 1986 a maior parte das laranjas, tangerinas e limões era oriunda de plantios de pés francos. Desde então, o incentivo à formação de novos plantios, utilizando mudas enxertadas de cultivares introduzidas, vem propiciando aumentos na produção e melhoria da qualidade dos...

Avaliação preliminar de clones de cupuaçuzeiro (Theobroma grandiflorum (Willd ex Spreng) Schum), nas condições de Manaus, AM. II. Produtividade.
Provedor de dados: 14
Autores: SOUZA, A. das G. C. de; GUIMARÃES, R. R.; NUNES, C. D. M.
Dentro do programa de melhoramento da cultura do cupuacu pretende-se selecionar variedades precoces, medianas e tardias, de modo a permitir o escalonamento da producao, favorecendo a agroindustria e melhorando a renda do produtor com a distribuicao da safra por varios meses e a consequente entrada de frutos no mercado durante todo o ano. Para estudo da distribuicao da safra, tomou-se por base as datas de colheita de 1989/90/91 e o total produzido. De modo geral, no trimestre correspondente aos meses de fevereiro, marco e abril houve maior concentracao das safras. Mas, a epoca da producao so podera ser melhor definida quando os clones atingirem a estabilidade, que, segundo a literatura, isso ocorre por volta dos dez anos da planta.

Influência do pH, cobertura morta e época de plantio na incidência da mela do feijoeiro.
Provedor de dados: 14
Autores: RITZINGER, C. H. S. P.; OLIVEIRA, R. P. de; VIEGAS, R. M. F.
A mela é a principal enfermidade do feijoeiro nas áreas produtoras da Amazônia. O agente causal, Thanatephorus cucumeris (Frank) Donk Rhizoctonia solani Kühn sobrevive no solo, tornando difícil o controle da doença. Objetivando avaliar o efeito do pH e da cobertura morta na incidência da mela, foram desenvolvidos, durante 3 anos consecutivos, experimentos na Fazenda Experimental do CPAF-Acre com a cultivar Rosinha, nas estações seca (abril) e das águas (outubro) em área infestada com o patógeno. Não houve influência do pH do solo na incidência de mela e confirmou-se a inviabilidade do plantio do feijão na estação das águas, mesmo utilizando-se cobertura morta do solo. Na época seca, a cobertura morta promoveu retardamento da epidemia, pois ocorreu menor...

Provedor de dados: 14
Autores: LOCATELLI, M.; LEÔNIDAS, F. das C.; SAMPAIO, N. F.
Nos últimos vinte anos, Rondônia tem sido alvo de um intenso movimento de migração e implantação de projetos oficiais de colonização. O resultado desses processos foi a intensificação da atividade agropecuária no Estado, responsável pela abertura de aproximadamente, 6.000.000 de hectares de florestas. Após um período de abertura acelerada da fronteira, houve uma redução no ritmo de ocupação. Recentemente, a colonização em solos de menor fertilidade não permitiu sustentação econômica adequada a grande parte dos agricultores e o empobrecimento do campo passou a ser evidente. Além da baixa fertilidade dos solos, a grande incidência de doenças e os baixos preços dos produtos agrícolas, também influenciaram no insucesso econômico. Nos últimos anos, houve um...

Drenagem para a cultura do feijão.
Provedor de dados: 14
Autores: SILVEIRA, P. M. da.
Dentre as opções de plantio em várzeas, o feijão aparece como boa opção para algumas regiões brasileiras, principalmente na sucessão da cultura do arroz. Entretanto, o comportamento desta leguminosa em várzeas, bem como de outras culturas, como milho e trigo, é pouco conhecido. O manejo da água de irrigação e/ou a drenagem reveste-se de fundamental importância, uma vez que a planta é extremamente sensível aos excessos de água, e da mesma forma, a toxidez de alguns elementos químicos comuns nesses solos.

Quatro gramineas forrageiras (Brachiaria decumbens, Brachiaria humidicola, capim andropogon e capim gordura) foram analisadas em termos de composicao mineral, para obter-se uma indicacao dos teores destes elementos nas pastagens cultivadas na regiao. De acordo com os dados obtidos dos minerais analisados, os niveis de calcio e fosforo estao abaixo das exigencias nutricionais, tanto para bovinos de corte como para vacas em lactacao. As concentracoes de magnesio nas quatro gramineas estudadas estao em niveis adequados. Para todas, a concentracao de cobre foi menor na idade mais avancada das pastagens. Ao contraio do cobre, as concentracoes de zinco foram maiores aos 90 dias de idade. O potassio, o manganes e o ferro estao em niveis superiores as exigencias...

Autores: COSTA, N. P. da; PEREIRA, L. A. G.; FRANÇA-NETO, J. B.; HENNING, A. A.
Durante cinco anos, entre 1977 e 1983, foram coletadas amostras de sementes de soja, provenientes de produtores estabelecidos no Estado do Paraná, para através da avaliação das qualidades fisiológica e sanitária, determinar-se as regiões mais aptas à produção de sementes. Na avaliação das amostras, foram utilizados os testes de "blotter", de germinação e de tetrazólio. Este último, com a finalidade de identificar os fatores que aceleram a deterioração das sementes (deterioração por umidade, danos mecânicos e ataque de percevejos). Durante o período de condução deste estudo, foram analisadas 1140 amostras da cultivar precoce Paraná, que era a mais cultivada no estado. Após os cinco anos de avaliação, o Estado do Paraná foi dividido em três regiões...

A proudman-function expansion of the m2 tide in the mediterranean-sea from satellite altimetry and coastal gauges
Provedor de dados: 5
Autores: Sanchez, Bv; Ray, Rd; Cartwright, De.
An empirical model has been derived for the semidiurnal principal lunar tide M2 in the Mediterranean Sea, excluding the Aegean Sea. The work is primarily an exercise in combining satellite altimeter data with tide-gauge data, through the use of specially constructed spatial basis functions. The tide-gauge data consist of M2 harmonic constants previously derived at 43 chosen coastal locations. The altimeter data consist of approximately two years of Geosat data in the form of collinear differences of sea-surface heights, corrected for orbit error by adjusting long sequences of global data. The tide is expressed as an expansion in Proudman functions - numerically constructed, orthogonal eigenfunctions of the velocity potential. The most important mode is...

Influence de l'azote et du phosphore sur la croissance et la toxicité de Prorocentrum lima (Ehrenberg) Dodge
Provedor de dados: 5
Autores: Morlaix, Martine; Lassus, Patrick.
Very few attempts have been made in order to investigate the role of nutrients on cellular growth and toxin production in dinoflagellates associated with DSP (Diarrhetic Shellfish Poison). Some preliminary results are presented here, aiming at a better knowledge of inorganic nitrogen and organic phosphorus effects upon division rate and toxin content of Prorocentrum lima (PL2V spanish strain). Nitrogen have a positive effect on growth rate, up to a threshold value of 880muM.l-1. Above this threshold the rate decreases. There is no effect on toxin content since okadaic acid and DTX1 cell contents remain low (4.8 +/- 0.5 pg.cell.-1) and steady. Phosphorus effect upon division rate follows a non-linear relationship, whereas cellular toxic content is inversely...

Accumulation and depuration of hydrocarbons in the mangrove oyster Crassostrea rhizophorae
Provedor de dados: 5
Autores: Delcastillo, C; Corredor, J; Morell, J.
Adult specimens of Crassostrea rhizophorae were exposed to diesel oil dispersed in seawater. The experiment consisted of a 10 days contamination period and 15 days depuration period. Oyster samples were extracted, and analysed by gas chromatography and UV fluorescence spectroscopy. The concentrations of n-alkanes, branched alkanes, unresolved complex mixture (UCM) and aromatic hydrocarbons were determined. The oysters accumulated the hydrocarbons rapidly, reaching a maximum concentration of 387.5 ug/g (wet weight). After exposure to uncontaminated seawater, the oysters were able to reduce their hydrocarbon load to 5.6 ug/g. The data indicates that C. rhizophorae is capable of preferential accumulation and depuration of hydrocarbons. Apparently, the oysters...

Depuration of copper nitrate and chloride in the Indian brown mussel Perna indica
Provedor de dados: 5
Autores: Kondajii, N; Menon, N.
It is understood that the rate of bioaccumulation and subsequent depuration of heavy metals in marine animals is influenced by the chemical state, as well as the kinetics of transformation between different species of chemical salts dissolved in water. The Indian Brown mussel, Perna indica, was exposed to copper nitrate and chloride, individually, to analyse the rate of accumulation, depuration, oxygen uptake and filtration rates. When supplied in very low quantities, environmentally realistic concentrations, the rate of accumulation of copper nitrate and chlorides showed variations. When the animals were transferred to sea water, these two salts did not show any clear cut differences in the depuration rate. Irrespective of the previous accumulation...

The effects of ionizing radiation, high energy electron beams, an depuration on shell stock oyster shelflife and Vibrio vulnificus content
Provedor de dados: 5
Autores: Dixon, D; Rodrick, G.
Total bacterial numbers were reduced three to four log cycles upon exposure of shell stock oysters to ionising radiation (60Co) at 1.0, 2.0 and 5.0 kiloGrays.Vibrio vulnificus was detected in the non-irradiated control shell stock oysters, however, it was not detected in any of the shell stock after 1.0, 2.0 and 5.0 kiloGrays of exposure. The shelflife of irradiated shell stock oysters and depurated oysters was also compared. Fifty percent of the irradiated oysters were dead within 12, 10 and 7 days at 1.0, 2.0 and 5.0 kiloGrays of exposure, respectively. In contrast, fifty percent of the depurated oysters were dead after 31 days.

Paralytic phycotoxin uptake by scallops (Pecten maximus)
Provedor de dados: 5
Autores: Lassus, Patrick; Bardouil, Michele; Ledoux, Martial; Murail, Ingrid; Bohec, Madeleine; Truquet, Philippe; Frémy, Jean-marc; Rohmer, Véronique.
It is difficult to apply sanitary standards for mollusc contamination by paralytic shellfish poisoning to animals not consumed whole. This problem is illustrated by the 1990 embargo on a Japanese shipment of frozen scallop muscle and gonad: the sanitary threshold applied to digestive gland (in Japan) does not guarantee that muscle and especially gonad are toxin-free. Accordingly, we performed experimental contaminations of scallops (Pecten maximus) from Port-en-Bessin (Normandy, France) using a toxic Japanese strain of Alexandrium tamarense. During the contamination/decontamination experiment on different tissues (digestive gland, muscle, gonad), extracts were obtained using cold acetic acid 0.1 N to maintain the perfect integrity of the toxin profile....

In order to comply with the requirements of the second Multiannual Guidance Plan concerning the fishing fleets in the EEC Member Countries, the French Secretary of State for the sea has implemented a decommissionning scheme in March 1991. To facilitate the withdrawal of an overall engine power representing 100000 kW, subsidies have been attributed to owners scaping their boat of selling it outside the EEC or for a purpose other than fishing. In parallel social measures were set to help the resignation or the retirement of skippers. In March 1992 applications concerning 975 vessels representing about 84 300 kW had been presented. Brittany accounts for 48.5 % of the boats and 43 % of the withdrawn power whereas the mediterranean ports represent only 9 % of...

Carbonic-calcium system, nutrients and total organic nitrogen in continental runoff to the galician rias baixas, NW Spain
Provedor de dados: 5
Autores: Perez, Ff; Alvarezsalgado, Xa; Roson, G; Rios, Af.
Biogenic element levels in continental runoff and their behaviour during estuarine mixing are studied in the Galician Rias Baixas for the upwelling season (May-October). Alkalinity, calcium, both with average concentrations of about 350 mumol.kg-1, and reactive silica, with 105 mumol.kg-1, show near conservative distributions along the estuarine side of the rias. A good agreement was found between values obtained by direct measurement in the river and those calculated by extrapolation to zero salinity from the mixing diagrams. On the other hand, nitrate (10-40 mumol.kg-1) and mainly phosphate (1 mumol.kg-1) are strongly affected by the biological activity of benthic algae during estuarine mixing. TON and ammonium in the innermost parts of the Ria de Arousa...

Peu d'études ont été réalisées sur la distribution, le transfert et les fonctions des plasmides existants dans les bactéries de l'environnement (Smith, 1970 ; Glasman et al., 1981 ; Hada et Sizemore, 1981). Hada et Sizemore (1981) en faisant une étude comparative sur le nombre des plasmides contenus dans 440 isolements de Vihrio marins du Golfe de Mexico ont démontré que l'incidence des plasmides est plus importante dans des isolements marins des sites pollués, que dans des isolements marins de sites non contaminés. Par contre, Burton et al. en 1982, en travaillant dans une rivière de South Wales, n'ont pas trouvé de différence significative entre les sites pollués et ceux non pollués sur le pourcentage total des isolements contenant des plasmides ainsi...

Utilisation des minéraux sédimentaires argileux pour la reconstitution des variations paléoclimatiques à court terme en Mer d'Arabie
Provedor de dados: 5
Autores: Fagel, N; Debrabant, P; Demenocal, P; Demoulin, B.
During the Late Neogene, the sediments of the Owen ridge (Arabian Sea) were able to record paleoclimatic variations because of tectonic stability and weak bio-turbation. These changes had a powerful influence on the western, northern and northeastern detrital supplies related to monsoon conditions and low-latitude aridity which developed during glaciary stages. In ODP Leg 117 sites, previous studies on the distribution of clay assemblages show a great variety of mineral origins and their fluctuating contribution to the Neogene sedimentation. Concurrent investigations of the sedimentological, magnetic, biogenic and geochemical properties of sediments have emphasized typical periodic sedimentary responses related to external forced functions of the earth's...

Dynamique de l'upwelling et variabilité spatio-temporelle de la répartition de la sardine marocaine, Sardina pilchardus (Walbaum, 1792)
Provedor de dados: 5
Autores: Kifani, S; Gohin, Francis.
A space-time approach is adopted in an attempt to understand changes in the availability of the central sardine stock along the northwestern Moroccan coast. The warming observed in 1987 and 1989, due to the decline in wind activity, seems to have some repercussions on sardine distribution. The decrease in upwelling activity seems to have favoured concentration in the vicinity of Safi, and thus rendered the sardines more vulnerable to the purse-seiners of this port. We seek to explain the failure of the link established by Belveze and Erzini (1983) between sardine availability and upwelling activity in thc northern area. Two hypotheses, taking into account the local hydrology or the tendency of pelagic species to aggregate in time and space, have been put...

Provedor de dados: 5
Autores: Bodin, P; Leguellec, C.
Harpacticoid copepods (Crustacea) of the Bay of Saint-Brieuc (Western Channel, France) were collected in winter and late spring 1988, at five intertidal and six subtidal sites. 140 species (many new and some rare) were identified, and several diversity indices (Shannon; Fisher et al.; Margalef) were calculated for the different sites: very high values were obtained at some of them, specially in heterogeneous sediment (H' = 5.26). Pearson's correlation coefficients show that diversity was positively correlated with TOM and depth. Correspondence factorial analyses applied to dominant species suggested the existence of an intertidal fine sand assemblage, with a low salinity ''facies'' (sensu Bodin, 1977), and a subtidal heterogeneous muddy sand assemblage,...

Extraction de granulats marins et activités halieutiques en Manche orientale
Provedor de dados: 5
Cette synthèse a pour but de présenter les gisements potentiels ou actuellement exploités, dans la région de Fécamp à Dunkerque. La production de granulats au Nord de la France est actuellement insuffisante pour répondre à la demande en matériaux. D'autre part, les sites terrestres exploitables sont de plus en plus rares et les contraintes d'environnement ont brutalement augmenté ces dernières années. Pour éviter une rupture de l'approvisionnement dans un futur proche, diverses solutions sont mises en oeuvre, et les extractions de sédiments meubles marins apparaissent comme un substitut éventuel. Il semble, au premier abord, que la réserve en matériaux est importante, mais les conditions d'extraction et la qualité souvent inadaptée des granulats entraînent...

L'huître creuse Crassostrea gigas en Bretagne. Résultats du réseau de suivi de 1991
Provedor de dados: 5
Autores: Le Bec, Claude; Mazurie, Joseph.
The year 1991 is the third one of the regional network on growth assessment of Crassostrea gigas in Brittany, wearing on 9 sites and 3 stations per site. 2 bags of 210 oysters, 18 month old, were placed in each station. Comparatively to previous years, the 1991 growth was moderate, and condition index inferior. However, the survival rates were very high (above 91 %) and most of the slight mortalities occurred a short time after stocking (as revealed by the sizes of dead shells). An improvement was also observed in the infestation rate by the polychaete Polydora sp..Most of the growth differences between sites and stations are still present. An analytical study including environmental variables would be necessary for explanations and will be tempted in 1993.

Autores: Peudenier, Isabelle.
La gynogenèse est le développement d'un oeuf activé par un spermatozoïde, mais sans participation du génome paternel. Sur le plan génétique, elle est équivelente à la parthénogénèse mais elle est déclenchée par d'autres facteurs. Chez l'huître creuse, Crassostrea gigas, l'inactiviation génétique du sperme par les UV est plus difficile à obtenir que chez les poissons, principalement du fait d'une grande variabilité inter-indivuelle de la motilité avant irradiation. Par ailleurs, l'absence constatée d'effet Hetwig rend plus délicate la définition d'un temps optimal d'exposition aux UV. Les haploïdes obtenus sont anormaux et n'atteignent pas le stade de larve D. La diploïdie peut être efficacement restaurée en retenant un globule polaire grâce au traitement...

Elements sur le comportement experimental et numerique de la structure d'un voilier de 7m70 en cours de navigation
Provedor de dados: 5
Autores: Baley, C; Cailler, M.
The experimental sailing boat "Mesure Z," has been designed and built on behalf of F.I.N., (the French marine industry association). This research project has been managed in close collaboration with Bureau Veritas, Ifremer and the CEA. The GRP hull is similar to that of a production sailing boat, but it has been designed as a transducer-hull, i.e. a hull sufficiently sensitive to allow measurements (hull strains, acceleration, spar loads, etc), due to its structure and mechanical characteristics. This paper presents different aspects of the experimental boat, the materials and structure of the transducer-hull, and the behaviour of the central and bow regions of the hull during sailing.

Experimental-study of the impact of hydrocarbons on the intertidal benthic community - the mahakam delta (east kalimantan, indonesia)
Provedor de dados: 5
Autores: Dutrieux, E.
Two simulated oil-spills in the Mahakam delta revealed the consequences of this type of pollution on the site's main benthic populations. The results of these trials differentiated between short-term (high toxicity similar to chemical pollution) and long-term effects (similar to organic pollution) of hydrocarbons. Two factors affected the distribution of the main macrofaunal species: intertidal height and degree of pollution. The latter was measured either by the initial quantity of oil spilled or by concentrations measured at each sampling. These trials also showed that dispersants were inefficient and that dredging treatments did not yield positive results. Often no treatment was preferable to these two treatments. A global statistical analysis was...

Les essais mécaniques a la DCN, de l'eprouvette aux structures
Provedor de dados: 5
Autores: Hoarau, P.
In order to correctly dimension surface ship hulls made of organic matrix composites, the DCN carries out different kinds of mechanical testing: Quasi-static and dynamic. Sample size varies from small scale (for material selection) to large scale (for the choice of assembling technology between deck and hull). As often as possible, the DCN performs correlation studies between its experiments and existing numerical tools, in order to improve the accuracy of computer modelling.

Estimating the North-Atlantic mean surface-topography by inversion of hydrographic and lagrangian data
Provedor de dados: 5
Autores: Le Traon, Pierre-yves; Mercier, Herle.
The non-linear inverse model described in Mercier et al. (1992) is used to estimate the mean surface topography of the North Atlantic and its formal error. The surface is based on a large hydrographic and Lagrangian data set and has spatial resolution of 2-degrees in latitude by 2.5-degrees in longitude. The formal error is between 4 and 8 cm. Contrary to previous estimations, this takes into account the errors with regard both to the density field and to the estimation of the velocity field at a reference level.

Croissance de Crassostrea gigas en Bretagne en 1989, mise en place d'un reseau d'acquisition de donnees
Provedor de dados: 5
Autores: Lebec, C; Mazurie, Joseph.
To provide updated information on the growth of Crassostrea gigas in Brittany, experimental stations on 8 sites (culture area) were monitored. Biometric measurements (length, width,...), meat composition (proteins, lipids, carbohydrates...), quality, survival and parasitism were observed after 7 months. A descriptive study by principal components analysis was conducted to find the most significative variables explaining the variability and classifying the sites. Six groups of station can be identified by their respective performances that have been screened in detail. An optimal strategy was discussed to establish a most efficient data network in Brittany. The yearly variations will be checked up and their correlations with environmental factors tested...

Cinétique du recrutement et croissance des juvéniles d'Owenia fusiformis Delle Chiaje en baie de Seine (Manche orientale)
Provedor de dados: 5
Autores: Dauvin, Jc.
The dynamics and growth of Owenia fusiformis juveniles were studied over a period of three months under different edaphic conditions in the eastern part of the Bay of Seine. Post-larval settlement was synchronous and showed the same high densities in different communities with or without adult populations. There was a rapid disappearance at the juvenile stage in the unfavourable bottoms. The distribution of the juveniles was gregarious. Growth was slow during the first month ; it was also highly variable. Growth differences were observed between stations: growth was higher in the station located just seaward of the Seine estuary. The relationships between edaphism, recruitment and growth of juveniles are discussed in relation to the changes in space and...

Nutrient behavior in 2 contrasting scottish estuaries, the Forth and Tay
Provedor de dados: 5
Autores: Balls, Pw.
The distribution and behaviour of nutrients (nitrate, nitrite, ammonia, silicate and phosphate) have been examined over the course of a year in two major Scottish estuaries, the Forth and Tay. Maximum concentrations of nitrate and silicate in both estuaries occur in winter, when mixing is conservative. By contrast maximum phosphate, ammonia and nitrite concentrations (notably in the Forth) are observed in summer, these are related to lower oxygen concentrations both within the water column and sediments. Phosphate, ammonia and nitrite concentrations are high in the Forth relative to the Tay. Phosphate behaviour in plots for both estuaries show some common features including removal at low salinity, mid estuary inputs and simple dilution at high salinity....

On the use of sea-level gauge data for satellite altimetry validation - a review
Provedor de dados: 5
Autores: Leprovost, C.
The altimetric sea-level data base supplied by the satellite Geosat has permitted numerous studies in the field of ocean science, some of which have addressed, through comparisons with island gauge observations, the question of the quality of the sea level products inferred from die Geosat dataset. The aim of this paper is to provide an overview of these recent studies, illustrating the usefulness of in situ sea level gauge measurements for satellite altimetry validation, to present briefly the status of the present worldwide sea level network, and to provide some guidelines on what must be done in the near future to improve this network further. It is shown that some of the discrepancies between altimeter products and tide gauge records are due to...

Les tendances du marché français de la salmoniculture
Provedor de dados: 5
Autores: Bailly, Denis.
Trout and salmon market is one of the major markets for fish in France. The domestic  production covers the demand for trout and it is very stable (30.000 tons) after a rapid expansion during the early eighties. With the rapid expansion of the world production, the price for salmon has been steadily decreasing since 1986. The French market for salmon depends completely on imports. The quantity imported increases more rapidly than the drop of the price. Salmon import is the main cause for the deficit of the trade of seaproducts in France. Salmon production is not likely to expand significantly during the coming years. The troutproduction sector seems to be at the point where the commercial benefits (quality control, trade scale economies, promotion...) may...

Analyse par elements finis d'un catamaran sur coussin d'air en sandwich
Provedor de dados: 5
Autores: Hermundstad, O; Moan, T; Nordal, H.
This paper deals with the structural analysis of transverse frames and bulkheads in sandwich catamarans. Finite element analyses of a frame and a bulkhead have been carried out, and the results are compared to those obtained from a finite element model of the entire craft. The frame and the bulkhead have been analysed with five different boundary conditions. Four idealized load combinations have been applied, and it is demonstrated that transverse frame models can give quite inaccurate results. This is due to the difficulty in deciding the relevant support springs to represent the interaction between the actual frame and the other part of the structure. When designing a new type of vessel, it is recommended to carry out a global finite element analysis...

Autores: Fraizier, Albert; Guegueniat, Pierre; Salomon, Jean-claude.
Time-dependent impact of seaward radioactive discharges on waters of one coastal station of the English Channel.  The disposai at sea of liquid waste from the nuclear fuel reprocessing plant at La Hague (CEA/Cogema) causes modifications to the radioactivity of marine waters in both space and time. Fluctuations in this radioactivity are controlled by many different parameters; to study these parameters, samples were taken, in particular, from a coastal site situated 5 km from the outlet pipe.  The overall impact of these releases on the radioactivity of sea-water depends on various factors, including the amount and frequency of discharges, the hydrodynamic regime of water masses in the region and local meteorological conditions. In order to assess this...

Larval rearings were performed with seawater either freshly pumped or after storage in a pond. Concerning bacterial populations these waters were characterized by a high diversity, little sized bacteria whose few of them (1%) were cultivable on Zobell medium. In the tanks, the bacterial ecosystem was modified by the presence of antibiotics, larvae and algae: the diversity was lowered, the cellular volume was increased by a factor 2 to 5, 100% bacteria were cultivable and chloramphenicol resistant, and their metabolism changed. Taxonomic screening showed no differences among the two waters neither at the beginning nor at the end of the rearings. However, depending on the water (stored or not) differences were identified for bacterial physiology and...

Autores: Pellerin, M.
Informations gathered in the mangrove of the Fort-De-France bay of Martinique (F.W.I.) showed a decreased physiological condition of Crassostrea rhizophorae in the south part of the bay explained by the presence of zinc and by physico-chemical parameters modified in the wet season, such as decreased salinity and decreased levels of nutrients. Bioaccumulation of zinc, lead and cadmium was highly correlated to sediment contamination. Contamination by pesticides and organochlorides was found mainly in oysters from the North part of the bay, characterized by industrial activities and agricultural inputs.

Iles et iliens (îles des Antipodes, des Caraibes et Saint Pierre)
Provedor de dados: 5
Autores: Antona, Martine.
Les îles et archipels français des Caraibes, de l'Océan Indien, du Pacifique et l'île de Saint Pierre et Miquelon concentrent la majorité des 1,670 millions de français habitant outre-mer. Il s'agit de terres étroites, éloignées de la métropole et distantes entre elles, éparses et souvent composées d'archipels. A l'exception de Saint Pierre et Miquelon, elles sont tropicales et soumises à des risques climatiques majeurs (cyclones). Leur superficie est réduite si on la compare à celle des territoires continentaux français d'outre-mer (Guyane et Terres Australes) mais elles sont au centre d'une surface maritime importante marquée par la pauvreté et l'inégale répartition des ressources biologiques et par la nature fragile des écosystèmes littoraux insulaires....

A comparison of two techniques to discriminate continental origin of Atlantic salmon (Salmo salar L.) off West Greenland
Provedor de dados: 5
Autores: Reddin, David; De Pontual, Helene; Prouzet, Patrick.
Two techniques of stock discrimination both utilizing scales, i. e. termed as classical technique and shape analysis, are compared for discriminating between North American and European Atlantic salmon (Salmo salar L.) caught off West Greenland. Three scales from each of 60 salmon were analyzed: 30 from North American and 30 from European-origin salmon collected from home rivers in 1982. The best results indicated misclassification and error rates of 0% for shape analysis and 5.0% and ± 1.7%, respectively, for the classical technique. A nested ANOVA indicated that variation was greater between scales of salmon of North American and European origin than from several scales from the same salmon. It was concluded that shape analysis with computer-aided...

Meiobenthos of the bay of saint-brieuc (north brittany, france) .1. quantitative distribution in subtidal and intertidal zones
Provedor de dados: 5
Autores: Leguellec, C; Bodin, P.
In the eutrophicated Bay of Saint-Brieuc (western English Channel, France), density and biomass of the multicellular meiofauna were estimated in different intertidal and subtidal biotopes, in winter and late spring. Mean annual biomass varies from 0.5 to 2.3 g.m-2 in the intertidal zone, and from 0.5 to 1.1 g.m-2 in the subtidal zone. Vertical distribution (0-5 versus 5-10 cm) of taxa was considered in the intertidal zone. Results are discussed and compared to literature data: figures were similar to those of comparable biotopes, and there was no detectable effect of eutrophication on meiofauna density and vertical distribution in this area. The ''seasonal stability'' of nematodes was in contrast with a clear annual cycle in harpacticoid copepods. Biomass...

Development of genomic probes for detection of hepatitis A virus and enteroviruses in shellfish
Provedor de dados: 5
Autores: Apaire, M; Leguyader, F; Besse, B; Billaudel, S.
The development of molecular biology techniques has modified research procedures for certain viruses, particularly hepatitis A virus (HAV) and enteroviruses. Accordingly, we designed cDNA and RNA genomic probes to detect viruses in shellfish in the environment. Better sensitivity was noted with RNA than cDNA probes: only 17/83 shellfish samples were positive with HAV and enterovirus DNA probes, where as 42/83 were positive with HAV and enterovirus RNA probes.

Autores: Loarer, Ronan.
Dans le cadre d'un programme de recherche sur le devenir des rejets urbains en mer, le comportement des particules issues de l'effluent de la station d'épuration de TOULON-Est a fait l'objet d'une étude depuis son traitement épuratoire jusqu'à sa dilution en mer. On a eu recours à des filtrations totales ou différentielles et à des microgranulométries par compteur COULTER. Le cycle journalier des matières en suspension est mis en évidence. Il fait apparaître un rendement épuratoire d'autant meilleur que la charge de l'effluent est forte à l'entrée de la station et concerne de grosses particules et/ou flocs : l'abattement en M.E.S. passe ainsi, en moyenne, de 30 % à 6h00 à 88 % à 13h00.

Répartition verticale des larves de Pectinaria koreni en baie de Seine orientale : influence sur le transport et le recrutement
Provedor de dados: 5
Autores: Lagadeuc, Y.
Variations in recruitment of benthic invertebrate species with pelagic larvae, which inhabit estuaries, can be reduced by the vertical distribution of larvae. In fact, they may be located in water masses in which net transport favours retention in the vicinity of estuaries. Such a hypothesis can explain the Pectinaria koreni population stability in the western bay of Seine. The vertical distribution of P. koreni larvae is in relation to the turbulence level. When turbulence is low, strong water stratification is present, and larvae are then most abundant under the halocline (in water masses where salinity is more than 30.5). Moreover, a strong ontogenetic migration is observed : young larvae occupy the upper part of the water column and old larvae the...

A evaluation and interpretation of czcs-derived patterns on the adriatic shelf
Provedor de dados: 5
Autores: Sturm, B; Kuzmic, M; Orlic, M.
The aim of the present paper is to investigate further the previously observed dichotomy in the Adriatic waters influenced by the Po river. To that end, an existing algorithm for pigment concentration retrieval has been improved and applied to the reprocessing of selected summer 1981 and winter 1981/1982 images of the Adriatic Sea. The sensitivity loss correction procedure has been included in the retrieval algorithm and rendered coherent with the atmospheric correction model. The model was also updated to allow for multiple Rayleigh scattering, and site-specific calibrated for case 2 waters of the Northern Adriatic. Our analysis of the images reinforces the previous finding (Clement et al., 1987) that two types of CZCS-derived patterns can be observed on...

On the influence of dissolved organic-matter on remote-sensing of chlorophyll in the straits of skagerrak and kattegat
Provedor de dados: 5
Autores: Karabashev, Gs.
An experimental techniques to estimate the influence of dissolved organic matter (DOM) on remote sensing of chlorophyll in water has been developed, based on the relationship between fluorescence and absorption of light by a substance. The profiles of fluorescence, chlorophyll content in sea water and estimates of light attenuation in water samples were used in the paper. These data have permitted to calculate the regressions linking fluorescence and light absorption at 450 nm by chlorophyll (ABC450) and by DOM (ABD450). The remote sensing needs no correction for DOM if M450 = 100* (ABC450/ABD450) much greater than 100. This technique has been applied to data collected during the international Skagex field experiment in the straits of Skagerrak and...

Performances de croissance et composition biochimique de Mytilus edulis (cultures suspendues du Pertuis Breton) en fonction de paramètres décrivant la richesse trophique du milieu
Provedor de dados: 5
Autores: Darnaudguilhem, Fabrice.
La croissance des mollusques cultivés dans les zones littorales, à faible taux de renouvellement d'eau, semble être limitée, au-delà d'une certaine biomasse, par la possibilité de nourriture, ce qui nécessite d'appréhender le mieux possible les capacités trophiques d'un écosystème. En particulier, dans le Pertuis Breton, s'est développéee récemment une nouvelle technique de culture mytilicole qui pourrait accroître à terme de 20% la biomasse de mollusques cultivés. Une étude de 9 mois et demi a donc été entreprise pour observer la croissance de deux populations de Mytilus edulis (moules de bouchots d'un an et moules issues de naissain de filière) sur ces nouvelles filières "subflottantes". Elle a été couplée à une étude du milieu pour étudier les...

Modèle hydro-sédimentaire du bassin de Marennes-Oléron : présentation et principaux résultats
Provedor de dados: 5
Autores: Raillard, Olivier; Le Hir, Pierre; Lazure, Pascal.
Depuis plusieurs années l'écosystème conchylicole de Marennes-Oléron est l' objet de modélisations de complexité croissante qui tendent à intégrer de plus en plus de processus physiques et biologiques (Bacher, 1989 ; Raillard, 1991) afin d'accroître le réalisme et le champ d'investigation de l'outil (Héral et al., 1991 ) . Confrontés au problème de la variabilité spatiale et temporelle des concentrations du matériel dissous et particulaire de l'eau, les travaux les plus récents ont pu mettre en évidence les limitations des modèles d'écosystème qui asservissent spatialement et temporellement la représentation des processus physiques à celle des mécanismes biologiques (Raillard, 1991).

Changes in hydrography and suspended particulate matter during a barotropic forced inflow
Provedor de dados: 5
Autores: Lund-hansen, Lc; Skyum, P.
This paper describes the changes in hydrography and the vertical distribution of suspended particulate matter (SPM) that occur during an inflow of highly saline water into a semi-enclosed bay. The study area is situated near the frontal zone in the Kattegat between the highly saline waters (32-34) of the North Sea/Skagerrak and the less saline waters (15-20) of the Baltic Sea. The water column at the frontal zone is stratified throughout much of the year. The study was carried out in a bay in the southwestern part of the Kattegat, and is based on CTD-observations, current direction and speed, and samples of suspended particulate matter obtained during the study period. The study shows that the hydrography of the bay is strongly influenced by the inflow...

Testing the effectiveness of tough resin systems for improving structural performance of joints in GRP ships.
Provedor de dados: 5
Autores: Norwood, L; Caulier, C.
A major concern in any composite structure is its ability to resist peel and shear loading; this becomes a more difficult problem where long delays in laminating have occurred or when dissimilar materials are joined together. In the case of mine countermeasure vessels, adhesion between stiffener and hull becomes critical when the ship is subjected to underwater shock loading. In order to reduce costs and improve the hull-stiffener bond, tough resin systems based on urethane acrylates have been developed to replace the mechanical crack-stopping system currently employed. This paper describes the benefits of urethane acrylates in the frame-hull application discussing the level of improvement over the mechanical system.

Circulation and upwelling off the coast of south-east arabia
Provedor de dados: 5
Autores: Currie, Ri.
Observations made during the International Indian Ocean Expedition provide the basis for a description of the summer circulation in the upper 500 m of the western Arabian Sea, off the coast of Oman. Under the influence of the south-west monsoon a pronounced geostrophic current develops along at least 1 000 km off the South-East Arabian coast between Ras Fartak and Ras al Hadd in May and the strong south-westerly wind brings about offshore transport of the surface layers between 55-degrees and 60-degrees-E. Water is upwelled onto the continental shelf from depths of about 150 m and this creates a strong negative sea-surface temperature anomaly along the coast, reaching a maximum development in July-August. With the decline of the monsoon upwelling ceases in...

Impact of the altimeter orbit on the reproduction of oceanic rings - application to a regional model of the gulf-stream
Provedor de dados: 5
Autores: Chassignet, Ep; Holland, Wr; Capotondi, A.
The impact of three altimeter sampling patterns (Geosat, ERS-1 and Topex-Poseidon) on the estimation of mesoscale eddy sea surface height anomalies is investigated in detail by making use of a regional model of the Gulf Stream and of an objective analysis. It is shown that, in a domain-averaged statistical sense, track sequencing does not appear to be of importance in the eddy field recovery. On the other hand, significant differences appear when one starts to look at specific processes such as rings. Qualitatively speaking, the manner in which a ring's signature is represented depends strongly upon the altimeter orbit choice. A higher space sampling such as ERS-1 is preferable in order to keep track of a ring, but to the detriment of its amplitude. A low...

Autores: Bastida, R; Roux, A; Martinez, De.
The benthic macroinvertebrate assemblages of the Argentine continental shelf were studied from samples of molluscs, echinoderms and bryozoans collected by the RN Shinkai Maru. Two major faunal groups were distinguished: one inhabiting the warmer inner shelf off Buenos Aires and northern Patagonia, and the other occupying the colder middle and outer shelf off Buenos Aires and most of the Patagonian shelf. These results confirm the traditional biogeographic division of the Argentine continental shelf into two provinces: Argentine and Magellanic. Furthermore, the results suggest the possibility of subdividing the Atlantic sector of the Magellanic province into two districts: Patagonian and Malvinean, under the influence of the Patagonian and the Malvinas...

Importance of geosat orbit and tidal errors in the estimation of large-scale indian-ocean variations
Provedor de dados: 5
Autores: Perigaud, C; Zlotnicki, V.
Geosat ERM data concerning the Indian Ocean over a period of 26 months were processed with two different techniques of orbit error reduction in order to improve the accuracy of estimates of large-scale meridional sea-level variations. The first technique removes an along-track polynomial of degree 1 over approximately 5,000 km; the second removes an along-track once-per-revolution sine wave (approximately 40,000 km). Averaged over the Indian Ocean, the difference between the two estimates represents 43 % of the total variance and 31 % of the annual variance. This difference contains both oceanic and error signals. Sea-level variations from both techniques show an error with a spectral peak at 7-degrees-6 zonal wavelength, 317-day period, propagating...

Crustacean genetic transformation is a new field of research in aquaculture, the aim being to select pathogen-resistant strains. Two genera were considered, either as a laboratory model (Artemia) or because of its economical importance (Penaeus). ln the two cases, early embryonic stages were studied to determine the experimental conditions for effective manipulation. Several methods were developped to introduce different kinds of molecules, specially DNA, into crustacean cells and embryos: microinjection, biolistic, electric treatment, lipofection. The transient expression of reporter genes, placed under the control of heterologous promoters, was observed subsequently to the introduction of DNA constructs (CMV-/acZ, hsp Drosophila-luciferase) by...

Interaction protection cathodique et biofilm en milieu marin

Autores: Guezennec, Jean; Antoine, Elisabeth; Conte, Max.
In marine environments cathodic protection using sacrificial anodes or impressed current is widely used. In aerated seawater a cathodic potential of – 800 mV/SCE is generally accepted as efficient against marine corrosion. Biofilms formed on the metallic surfaces exposed to seawater can promote localized corrosion and interfere with the cathodic polarization process. Experiments were conducted both in natural environments and with a monoculture of a marine bacterium in order to understand the relationship between cathodic protection and biofilm formation. Results indicated that, in the former case, there was no evidence that biofilms significantly affect the cathodic current demand. Conversely, in sterilized seawater inoculated with a single bacterial...

Uptake and depuration of the opaque and translucent morphotypes Vibrio vulnificus and the effects of oyster passage on virulence
Provedor de dados: 5
Autores: Groubert, T; Oliver, J.
Vibrio vulnificus is an estuarine bacterium which is known to be a significant human pathogen. It occurs in high numbers in oysters and other molluscan shelfish, where it is part of the animals' normal flora. V. vulnificus occurs in two colony morphotypes; the opaque, encapsulated variety is virulent, whereas the translucent, non encapsulated variety is avirulent. Studies were carried out to determine if the opaque and translucent morphotypes were taken up by oysters (Crassostrea virginica) at different rates, and whether UV - assisted depuration proceeded at different rates. Possible interconversion of the opaque and translucent morphotypes was also examined, as was the possibility that the virulence ofVibrio vulnificus would be modified following passage...

Autores: Robert, Rene; Maurer, Daniele.
A new method of oyster cultivation, the Stanway oyster cylinder, has been experimented in the basin of Arcachon since the autumn of 1989. The first observations on three species of juvenile bivalves showed that this system could be successfully used with the Japanese oyster Crassostrea gigas . A comparative study of the growth of this last species, reared in cylinders and oyster bags, has been carried out since spring 1990. The first results showed that the growth of juveniles and 18 months old oysters in cylinders is not as good as in bags. On the other hand, mortality did not differ between both techniques: less than 3%. This new system seems to be less efficient than the traditional French way of rearing oysters. However, an improvement in the quality...

Contribution of satellite altimetry to the observation of oceanic mesoscale variability
Provedor de dados: 5
Autores: Le Traon, Pierre-yves.
The long duration and low noise level offered by the US Navy's Geosat altimeter opened up new scope for the quantitative use of satellite altimetry in observing oceanic mesoscale variability. This paper, centered on recent results from Geosat data, shows how satellite altimetry contributes to the description of oceanic mesoscale variability. The methods commonly used to extract the oceanic mesoscale signal are first recalled. We briefly discuss their impact on the signal, and measurement errors. We then look at the results of comparisons between altimeter data and in situ measurements, and demonstrate that Geosat data are suitable for observing mesoscale variability. The unique contribution which altimetry can make comes from its global space-time...

Autores: Pancuccipapadopoulou, Ma; Siokoufrangou, I; Theocharis, A; Georgopoulos, D.
Zooplankton composition and vertical distribution, and its relation to the hydrological regime are studied in the NW Levantine and SE Aegean Seas. The area is characterized by intense sub-basin and mesoscale variability. Various gyres and eddies as well as currents and jets affect the vertical and horizontal transport of the identified water masses. Furthermore, in late winter LIW is generated exclusively in this region of the Eastern Mediterranean, mainly in the Rhodes cyclonic gyre and to a lesser extent in the Cretan Sea. Generally, zooplankton density and taxa numbers decreased with depth. Four groups of copepod species were distinguished according to their vertical distribution: epipelagic, epi-mesopelagic, mesopelagic and bathypelagic. From 0-500 m,...

Baltek Corp. is currently in the process of introducing 3 new products: density select material, AL-600/10 and DecoLite panels, that reduce weight and cost. Creep results on typical core materials have shown that only end-grain balsa (EGB) and 9.0 lb. Nomex honeycomb were capable of continuous operation at 160 F (71 degree C). In reverse bending fatigue studies, EGB has a fatigue limit 2-2.4 times that of the PVC foams. Finally, while EGB by itself is a ASTM E-84 Class 2 material, with the proper skins and resin system, it can easily meet Class 1 requirements.

Autores: De Verdelhan, Claude; Gros, Philippe; Catanzano, Joseph.
(i) La pertinence du thème est attestée par la richesse de la littérature internationale qui lui est consacrée. 11 convient au demeurant de noter la présence de publications de l'IFREMER dans ce même domaine. Les principaux acquis procèdent généralement d'approches descriptives, permettant de disposer à ce jour d'un inventaire quasi exhaustif des différents outils de gestion classiquement mis en oeuvre. D'ores et déjà il apparaît que la question de la transférabilité de mesures de gestion (e.g QIT, Licence, PME...) soulève plusieurs interrogations: cohérence juridique, acceptabilité, contrôle, coûts, efficience... Mais surtout, poser l'étude de la régulation en termes d'analyse du comportement d'un système élargit le champ des investigations au delà du...

Impact de l'émissaire de Toulon-Est sur les sédiments de la Grande Rade. Aspects granulométriques, chimiques, bactériologiques et toxicologiques
Provedor de dados: 5
Autores: Loarer, Ronan; Arnoux, A.; Bodennec, Guy; Martin, Y.; Pagano, G.
L'étude des apports particulaires de la station d'épuration de Toulon-Est et des polluants qui leur sont associés a permis d'acquérir des informations concernant leur impact sur les fonds de la Grande Rade. Une campagne de prélèvement des sédiments superficiels fait apparaître, à travers la granulométrie, l'analyse des contaminants organiques et métalliques, la caractérisation de la matière organique, la répartition des bactéries d'origine fécale et des tests d'embryotoxicité sur des oursins, une zone d'impact maximal dans le Sud-Ouest du rejet. Celui-ci paraît limité à une distance allant de 500 à 1 500 mètres, avec des maxima entre 250 et 750 mètres, selon les traceurs et la direction envisagée.

Microflambage et rigidite des composites a fibres longues: Theorie et experiences
Provedor de dados: 5
Autores: Ferron, G; Cardin, C; Grandidier, J; Potier, F.
An original flexion-compression device designed for investigating the elastic behaviour in compression is presented, and the effect of the loading mode on the characteristics of failure is then described. Results on glass-epoxy resin unidirectional composites and laminates are discussed. In the literature the failure of laminated in compression is often ascribed to a mechanism of fiber microbuckling. To discuss the quality of these models, a periodic array of stiff and soft layers is analysed by an asymptotic method. The results are compared with those in the literature and with experimental observations.

Autores: Lafaurie, M; Narbonne, Jf; Galgani, Francois.
L'évaluation du risque écotoxicologique réclame des données sur les relations entre les concentrations des polluants et leurs effets biologiques in situ. La validation in situ d'un biomarqueur permet une évaluation des méthodes de biosurveillance et des tests d'écotoxicité, une estimation du danger lié à un composé chimique et l'établissement de normes de qualité des eaux. Des exercices d'intercalibration sont nécessaires à la qualité et à la reproductibilité des résultats.

A comparison of dissolved and particulate mn and al distributions in the western north-atlantic
Provedor de dados: 5
Autores: Yeats, Pa; Dalziel, Ja; Moran, Sb.
The dissolved Mn distribution on an oceanographic section along 50-degrees-W in the western North Atlantic shows decreasing concentrations in the offshore direction in the surface layer and with depth at the deep water stations. Leachable particulate Mn concentrations are low in the open ocean surface waters and elevated at intermediate depths. Dissolved Al concentrations in the surface layer are higher in the open ocean than on the shelf and the vertical distributions are characterized by surface maxima, a subsurface minimum at almost-equal-to 1 000 m and increasing concentrations in the deep waters. Leachable particulate Al concentrations are elevated on the shelf and in open ocean surface waters compared to the intermediate and deep waters. The Deep...

Atlas de fractographie des composites
Provedor de dados: 5
Autores: Jeannetaud, P; Krawczak, P; Bequignat, R; Pabiot, J; Bord, C; Vancon, M; Bard, M; Lemascon, A.
Fractography deals with the microscopic study of the fracture surfaces of a structure in order to define the initiation and the propagation of the damage and then the failure history of the structure (stress, environment ...). Today, we are able to identify the causes of the failure of metallic parts based on pictures of typical fracture surfaces, but there is nothing similar for composite materials. However, the increasing amount of literature devoted to fractography, as well as the constitution of "brain storming" groups on a European level confirm scientific interest in this fracture analysis mode that permits a better understanding of the existing relationship between the material's microscopic structure and its macroscopic mechanical behaviour. In...

Ecosystem Modelling: sensitivity of physical characteristics to spatial box design
Provedor de dados: 5
Autores: Bacher, Cedric.
The residence time of the water in different parts of the Marennes-Oléron Bay is one important characteristic of the biological system (Raillard, 1990). For instance, the primary production potentiality of a given area depends on the local turbidity and the residence time of the waters in that area. Further, global assessments of the nitrogen flow between the biological compartments and inflows from the ocean or the Charente river derived from the ecosystem model by Raillard (1990), showed the predominance of the latter term onto the former. A new hydrological model of the Marennes-Oléron Bay yielded two dimensional velocity fields for sorne standard tidallevels: neap-tide, spring-tide, mean tide (Lazur, unpub.). These computations were the basis for the...

On the use of satellite data in a general-circulation ocean model - altimeter and scatterometer data
Provedor de dados: 5
Autores: Boukthir, M; Verron, J; Barnier, B.
This paper examines how satellite altimeter and scatterometer measurements could be jointly used in a numerical ocean model in an attempt to simulate a realistic ocean circulation. The aim of the study is to determine quantitatively how sensitive the efficiency of the assimilation process may be to the variability of the wind stress curl and to evaluate the ability of the Topex/Poseidon altimetric data to correct for the sampling of scatterometer wind data that is to be provided by the forthcoming ERS 1 and NSCAT satellite missions. The model is quasigeostrophic, eddy-resolving and multi-layered, and is applied to the prognostic description of the mid-latitude ocean circulation in a schematic box ocean. Satellite altimeter data are simulated from model...

Fatty acid composition in deep hydrothermal vent symbiotic bivalves.
Provedor de dados: 5
Autores: Ben-mlih, F; Marty, Jc; Fiala-médioni, A.
Fatty acids in deep hydrothermal vent bivalves have been analyzed. Their composition is completely different from that of a littoral mussel collected in the Mediterranean sea. The distribution of fatty acids in the littoral mussel is characterized by a predominance of polyunsaturated fatty acids (20:5n-3, 22:6n-3) reflecting the planktonic origin of the food. Vent bivalve fatty acid distribution is dominated by an abundance of the monounsaturated acids (double bond in the n-7 position) 16:1n-7, 18:1n-7, and 20:1n-7 which are clearly of bacterial origin and give an indication of the symbiotic bacterial activity in the bivalves. Differences between the fatty acid composition of the bivalves from two hydrothermal sites (13 degrees N and Galapagos) and...

Effects of temperature abuse on survival ofVibrio vulnificus in oysters
Provedor de dados: 5
Autores: Murphy, S; Oliver, J.
Of the several bacterial diseases which may result from consumption of shellfish, those caused by marine bacteria of the genus Vibrio are the most abundant. In the United States, up to 10,000 non-fatal cases per year are estimated to be caused by the various members of this genus. More than 95% of all deaths in the United States which result from seafood consumption are caused by a single bacterium, Vibrio vulnificus. The bacterium is a normal inhabitant of estuarine waters, and occurs naturally in especially high numbers in molluscan shellfish. Infections following consuption of raw or undercooked shellfish, especially oysters, result in fatality rates of over 60%. Because most oysters in the United States are transported large distances before marketing,...

Comme toute industrie, l'aquaculture doit pour se développer dans une région ou un pays donné être capable de fournir une offre concurrentielle en termes de quantité, de qualité et de prix. Pour atteindre cet objectif, des choix se posent en matière de dimensionnement d'entreprise, de niveau d'intégration, de diversification et d'organisation de la production. Pourquoi n'y a-t-il pas qu'une seule sorte d'entreprise adoptant une technique standardisée ? La grande diversité observée actuellement dans le secteur aquacole résulte de la prise en compte d'autres facteurs que la seule maximisation du profit en situation de concurrence parfaite. En effet, la forte dépendance du milieu naturel et la maîtrise technique encore imparfaite font que le fonctionnement...

Altimetry and models in the tropical oceans - a review
Provedor de dados: 5
Autores: Arnault, S; Perigaud, C.
Tropical oceans play a key role in climatic variations. Ocean-atmosphere interactions induce large-scale and low-frequency variations which, due to the specificity of tropical ocean dynamics, are very difficult to observe with traditional in situ measurements. During the past twenty years, a variety of numerical models of diverse complexity have contributed much to the description, understanding and prediction of ocean variability in the tropics. However, the capacity of these models to simulate adequately the ocean variability heavily depends on the accuracy of the atmospheric forcings and that of initial conditions. Satellite altimetry provides a unique opportunity to avoid the problem of scarce and non-synoptic in situ data coverage for the large-scale...

Synoptic estimates of an eddy field in the north-atlantic current

We show various synoptic estimates of the North Atlantic Current (NAC) eddy field in a domain 450 x 350 km at 52.5-degrees-N 25.0-degrees-W in the theoretical path of the NAC. Temperature, salinity, and surface streamfunction estimates are derived from the AthenA hydrological data collected in the summer of 1988. These estimates are discussed and compared with two surface streamfunction estimates obtained from Geosat altimetric measurements: one statistical, and the other resulting from quasi-geostrophic assimilation. The estimates show a frontal structure associated with a jet, sharply separating cold and fresh water to the north from warmer and saltier water to the south. Temperature and salinity values on both sides of the front are consistent with...

La prise de conscience générale de l'intérêt de protéger l'environnement conduit, de plus en plus, à intégrer cette composante dans les programmes d'aménagement. La frange côtière est un milieu particulièrement fragile. Les écosystèmes littoraux subissent, de façon parfois excessive, la pression des activités humaines. Celles-ci sont souvent conflictuelles : le développement des cultures marines et la préservation des ressources halieutiques nécessitent des conditions optimum de qualité du milieu, perturbées par les apports agricoles ou les rejets urbain.

Les organismes marins, et en particulier les coquillages, ont la propriété d'accumuler les contaminants présents dans le milieu. Le consommateur va donc retrouver dans son assiette ces produits indésirables et peut-être nuisibles à sa santé. Le facteur de concentration entre l'eau de mer et les tissus des coquillages peut être très élevé. Ce qui est un inconvénient pour le consommateur devient d'un intérêt primordial pour les environnementalistes cherchant à évaluer la qualité du milieu marin.

Autores: Gilles, S.
The study was carried out at two sites, the island of Carabane, near the ocean, and the village of Djivent, 60 km by water-way from the mouth of the Casamance River. On the first site, the rise of water temperature commands the spat fall from March to October with a maximum peak in July. Because of a heavy biological competition, oysters can only survive within the intertidal zone. On the second site from August to November, which corresponds with the end of the rainy season, the decrease of salinity induces spawning and settlement of young oysters. Because of the heavy salinity variations there is a weak biological competition and young oyster can easily survive in permanent immersion as within the intertidal zone. On both sites, the growth is linear but...

L'eau douce devant Monaco
Provedor de dados: 5
Autores: Rapaire, Jl; Prieur, L.
Rises in the water level of the Roya, the closest river to Monaco, are followed by a lowering of salinity in the coastal area that is all the more intense and synchronous as we near the shore and the river mouth, as well as at the sea surface. By comparing the mean salinity six miles offshore with that of the bay, between 1976 and 1983, it is found that the fresh water volume contained in the first metre below the surface of the bay is equivalent to the cumulative flow of the Roya in three hours. Studies of lagged correlations between the flow of the Roya and salinity measured in the bay and further offshore indicate that during hot and calm weather the mixing area between fresh water and sea water spreads to a greater extent seawards and is more...

Monitoring of pollutant biochemical effects on marine organisms of the french coasts
Provedor de dados: 5
Autores: Galgani, Francois; Bocquene, Gilles; Truquet, Philippe; Burgeot, Thierry; Chiffoleau, Jean-francois; Claisse, Didier.
The establishment of a network to assess pollutant effects is a current concern of international bodies such as the North Sea Task Force, the International Council for the Exploration of the Sea and the Intergovernmental Oceanographic Commission. With respect to the French coasts, three major considerations have been defined : the choice of monitoring areas ; the determination of a target species according to different criteria such as wide distribution, limited migration and contact with pollutant-rich sediments; and the selection of suitable parameters. This paper concerns the strategy adopted for the French coast.

Autores: Mortensen, Stein Hàkon; Bachere, Evelyne; Le Gall, Ghislaine; Mialhe, Eric.
Infectious pancreatic necrosis virus (IPNV), serotype N1 isolated from scallops Pecten maxjmus in Norway, was propagated and used in both inoculation and bath challenge experiments with scallops in vivo. Although virus titers measured in scallop tissues decreased, depuration of virus was not complete during the experimental periods. TPNV was still detectable 11 mo after injection. The highest virus titer was found in the hepatopancreas, but virus was also detectable in other tissues, as well as in the hemolymph. After a bath challenge, uptake of IPNV was shown. Virus was present in hepatopancreas, gonad, kidney, mantle, gill, rectum and in the hemolymph 1 d after the uptake.

Effect of storage on the quality of purified live Pacific and Sydney rock oysters

In December, 1990, the N.S.W. Minister for Agriculture and Rural Affairs removed the Pacific oyster (Crassostrea gigas) from the noxious fish list for the Port Stephens area, permitting it's cultivation. As Port Stephens Pacific oysters are grown intertidally, similar to Sydney rock oysters (Saccostrea commercialis) there was a belief that they may have different storage requirements to overseas Pacific oysters which are cultivated in deep water exclusively. Consequently, the keeping quality of this oyster and it's compliance with N.S.W. bacteriological regulations were examined. Port Stephens Pacific and Sydney rock oysters were purified, then stored at refrigeration and ambient temperatures. Levels of faecal coliforms, standard plate count and Vibrio...

Autores: Minas, Hj; Minas, M.
An analysis of tropical upwelling systems shows a great range in the rate of increase of the standing stock expressed in terms of the water column chlorophyll content. Grazing appears to be the main factor responsible for lowering the rate of increase, especially in moderate and strong High Nutrient-Low Chlorophyll (HNLC) waters. A simple model comparing Net Community Production (NCP) rates with observed chlorophyll increase rates, leads us to conclude that phytoplankton population must present high specific growth rates on a daily rhythm in order to overcome grazing. Maximum specific growth rates (V(max)) calculated for daily total production (TP) are, in the two main upwelling areas, 137 d-1 off NW Africa and 1.04 d-1 off Peru. For extreme HNLC...

Analyse des stries de croissance des post-larves de coquilles Saint-Jacques (Pecten marimus). Méthodologie et perspectives d'application pour la description de stress d'élevage
Provedor de dados: 5
Autores: Baillon, Nathalie.
Cette étude s'inscrit dans le cadre de travaux orientés vers la compréhension des stress du passage en mer. Cette approche s'effectue grâce à des analyses purement zootechniques réalisées par PHILIPPE (1991) et par l'observation des stries de croissance visibles sur les coquilles du naissain de Pecten maximus. Cette étude est tout d'abord axée sur la mise au point d'une méthodologie d'analyse de ces stries. La question est ensuite de cerner l'utilité de ces stries dans une meilleure perception du stress consécutif au passage en mer affectant les juvéniles de coquille Saint-Jacques issus d'écloserie.

La culture suspendue de Chlamys varia , de la nourricerie a la taille commerciale, en Galice (Espagne)
Provedor de dados: 5
Autores: Cancelo, M; Guerra, A; Fernandez, A; Gabin, C; Fernandez, J.
Chlamys varia has a great potential of culture in Galicia, and it is likely to be among the pectinids, both a complement and an alternative to raft mussel culture which is dominant in the region. The present work attempts to analyse the growth of nursery spat of 6.46 plus or minus 0.75 mm reared in a raft during fifteen months in different depth and densities. The final average height is between 36.49 plus or minus 0.56 mm in the group of high density in the bottom and 40.75 plus or minus 0.55 mm in those of low density at the surface. Different culture densities have shown significant differences in growth (p &lt; 0.001). However, different depths have not shown such differences. At the end of this period mortality is lower than 2% in all groups.

Pour un suivi conjoncturel de l'environnement : à propos des ports du littoral français
Provedor de dados: 5
Autores: Ferlin, I.
This study aims to integrate the problems associated with port development and related activities in an economic monitoring programme that surveys all the activities associated with the marine environment. The economic monitoring programme in this sector also includes studying coastal spatial planning. This type of study concerns the creation and remodelling of sites that involve investments. We can consider two types of coastal spatial planning: one which integrates port development, tourism, aquaculture and fisheries and one that deals with the marine environment (Abric, 1989). Economic surveys of port development on French coasts supposes that the problem of identifying information sources have been resolved and the sectors and the activities that...

Autores: Angeli, J.
After a general presentation of the Thau lagoon together with its geographic location, socio-economic activities linked to shellfish culture and fishing, this paper investigates the health conditions of the shellfish harvesting areas. I he influence of heavy rainfall following a prolonged drought period is underlined as a determining factor of the momentary bacterial pollution in the harvesting areas, leading to a suspension of sales based on analyses relying solely on the detection of faecal coliforms. As of 1989, bacteriological monitoring was reorganized in the form of a data collection network taking into consideration environmental assessments of water quality as well as shellfish hygiene in order to protect consumer health.

Le programme d'amélioration des techniques d'élevage de la Chevrette Macrobrachium rosenbergii en Guyane constitue la deuxième phase du programme d'expérimentation mené sur la station IFREMER de Kourou. Jusqu'en 1988, l'effort a porté sur l'analyse du système continu classique utilisé par l'ensemble des producteurs de Macrobrachium aux Antilles et en Guyane. A partir de 1988, il apparut que la résolution des problèmes posés par son application passait par l'utilisation de schémas de gestion de la population en mode discontinu. Les expérimentations ont donc porté sur les principales conditions d'élevage susceptibles d'améliorer l'efficacité du schéma d'exploitation de la population.

Depuration: An administrative overview
Provedor de dados: 5
Autores: Somerset, I.
At the 1964 National Shellfish Sanitation Workshop, Mr. Eugene Jensen presented a thought-provoking paper outlining the rationale for the depuration of shellfish. Mr. Jensen noted that "we are committed to the principal that shellfish must be as safe to eat as other ordinary food" and that "the problems of assuring the sanitary quality of coastal areas will increase rather than diminish. This is not the same as saying that pollution will increase" (Jensen, 1964). It is recognised that additional use of the waters and shore areas will have adverse impacts on the water quality and shellfish resource quantity and quality. If we are to maintain a program which will permit the consumer to eat shellfish in any form they choose, we must develop the means to...

Extending a reflection upon the flexibility of artisanal fishing (DABAT et al., 1990; REY, 1991-b), the aim of this communication is linked to a set time scale that would be short term. Changing the time scale modifies the level of interrogation: the point is no longer to consider flexibility from a productive point of view as the property of a system but decision-making flexibility as an adaptation process in the context of a transformation of the system.

The change in composite material properties when these are exposed to a marine environment is of considerable importance to both designers and users of these materials. In this paper new materials are first studied, composites composed of a glass fibre reinforced thermoplastic PPS matrix. It is shown that their poor interfacial resistance to moisture ingress compromises severely the advantage of using a matrix which does not absorb moisture. In the second part of the paper the application of two non-destructive test techniques for following damage development, based on ultrasonic wave propagation and vibration (modal) analysis, are described. These are complemented by first results from a study using fracture mechanics tests to characterise delamination...

Autores: Dao, Jean-claude; Caisey, Xavier.
Since 1973, spat collection bas been conducted by IFREMER in the bay of Brest. This collection aimed at providing juveniles of Pecten maximus (1973-77) and then Chlamys varia(1977-87) in order to improve the management of the fishing grounds of the two species.  Since 1982, the efforts have been focussed on the P. maximus spat production through the hatchery/nursery systems and the intermediate culture. Juveniles are seeded above a minimum size to create an additional population. In parallel, the levels of spat yied/collector have been followed as a pre-recruit index.  At present time, there is no increase of spat collection during 1985-1990. Moreover, the results rise up the question of water quality in the bay of Brest for this group apparently very...

Autores: Omnes, Marie-helene; Normant, Yvon; Suquet, Marc; Fauvel, Christian.
Egg production data from individual hand stripped female turbot were collected and analysed over several consecutive spawning seasons, on natural or shifted conditions. Egg quantity, egg viability and number of spawns were examined from one spawning season to the other, and inside the spawning season. These parameters seemed to increase from a year to the next one, except for the oldest fishes. Spawns were spread over a three-month period and occurred at the same time in the period in successive seasons for most females. Egg production seemed related to the feeding level and the earliness of spawning season appeared depended on the growth rate. Without sand substrate in tanks, injuries could increase therefore no significant differences were observed in...

Autores: Tamanai-shacoori, Z.; Jolivet-gougeon, A.; Cormier, M.
La recherche des coliformes dans les milieux extérieurs, en particulier dans l'eau, par les techniques traditionnelles nécessite en premier, la filtration d'une quantité suffisante d'eau, suivie de la culture des filtres sur un milieu sélectif. Ceci permet d'identifier les bactéries utilisant le lactose en tant que seule source de carbone (Greenberg, 1985). Les Escherichia coli entérotoxigènes sont ensuite recherchés par les tests de détection de l'entérotoxine LT effectués sur le surnageant de la culture bactérienne. Ces tests sont basés sur l'activités biologique (culture sur cellules vero et Y1) ou immunologique (latex, GM1-ELISA, Biken, ...) et/ou radio-immunologique (Sack and Sack, 1975 ; Honda et al., 1981 ; Ito et al., 1983 ; Ristaino et al., 1983)....

Autores: Croci, L; Demedici, D; Franco, E; Gabrielli, R; Dipasquale, S; Toti, L.
The depuration effectiveness of Poliovirus 1 and HAV contamined mussels, when subjected to flowing ozonized water, was evaluated. Mussels were experimentally contamined and then depurated up to 72 hours using a pilot depuration system with ozone treated and untreated water. The results showed that viral infectivity titter decreased more rapidly in mussels subjected to ozonized water (from 10 super(4) TCID50 to 10 super(1.5) TCID50 per ml of Poliovirus 1 but in the following period it remained unchanged. Also HAV was detected in the mussels after 72 h of depuration.

Autores: Simeone, M; Davies, Peter.
In the last two decades, the Finite Element Method has been growing as a powerful tool for the structural analysis of the ship hull, but in nautical construction the use of this method has been related mainly to steel or aluminium hulls. In a metallic structure the material is homogeneous and isotropic and the plate, or the stiffened plate, behaves as an orthotropic plate, which means orthogonally anisotropic with three mutually perpendicular planes of symmetry; on the contrary, when considering a composite hull panel the scheme ought to be different, because there arise two different problems, which ensue from the structural characteristics of the composite sandwich panel. Firstly, the Element Stiffness Matrix must take into account the natural anisotropy...

A national program started in 1989 to drive researches on Ruditapes philippinarum brown ring disease correlated with a vibrio called P1. The researches have concerned epidemiological surveys on spats and adults, treatment methods, diagnostic techniques, and anatomical and functional studies about the vibrio-clam relations. The transmissions of the disease appeared mainly related to contaminated manila clam seeds, with secondary horizontal propagation. The brown ring formation appeared to be caused by a periostracum deterioration. Taking into account some of these results, an adapted cultural technique including special care of seeds and decreased densities was proposed to the farmers.

Innovative rapid solid-phase immunobead assay for the detection of okadaic acid and related DSP toxins in shellfish
Provedor de dados: 5
Autores: Park, D; Fremy, J; Marcaillou, L; Gamboa, P; Gleizes, E; Masselin, P; Goldsmith, C.
The solid-phase immunobead assay (Ciguatect super(TM)) has been optimized to detect toxins associated with diarrheic shellfish poisoning (DSP). The Ciguatect super(TM) test kit utilizes a membrane to bind the toxins and a monoclonal antibody-latex bead solution as the determination step. The presence or absence of okadaic acid (OA) and related toxins is determined by binding the toxins to a membrane attached to a plastic strip and exposing the toxins ladened membrane to a monoclonal antibody-colored latex bead complex which has a high specificity for OA and related polyether compounds. The intensity of the color on the membrane denotes the presence of the toxins. A rapid extraction method (REM super(TM)) has been developed to allow for confirmation of...

Autores: Baud, Jean-pierre; Haure, Joel; Bodoy, Alain.
Intensive ongrowing (from 28 mm to the commercial size, 35 mm) of the Manila clam Ruditapes philippinarum was studied in experimental raceways with a natural bottom of clay. The factors controlled were rearing density (100, 200, and 300 individuals/m2) and food concentration (34.0 and 68.1 µg.1-1 chlorophyll a). Food was produced from a batch culture of Skeletonema costatum in a large volume (50 m3), thanks to the fertile ground and saline water. Best results regarding final size were obtained in the vicinity of the inflow with a densilY of 100 individuals/m2. However it was a density of 300 individuals/m2 which appeared from the following results to be the optimal choice for intensive rearing: the survival rate was 84 %, the final biomass was 4 kg/m2 and...

Relationships between benthos and sedimentary organic matter quality were analyzed in the West Gironde Mud Patch (WGMP), on the shelf of the Bay of Biscay, off the Gironde estuary, as part of the multidisciplinary national programme Ecomarge, a JGOFS-France contribution. At three stations located on an east-west transect and at different periods from 1985 to 1988, the following parameters of the sediment were analyzed: POC (particulate organic carbon); SIGMA (sum of easily extractable macromolecules thought to be the most degradable part of particulate organic matter); pigments as indices of organic matter quality; ETS (electron-transport-system) activities and meiofauna densities as indices of benthic responses. Sediments from the WGMP have an overall low...

Autores: Bensch, Alexis; Bacher, Cedric; Baud, Jean-pierre; Martin, Jean-louis.
The growth of Ruditapes philippinarum was modeled with an energetic budget equation. Clams were fed with Skeletonema costatum in experimental units during 6 months. The filtration and respiration terms of the budget were depending on the temperature and the dry weight. The spawning effort was represented by an allometric relation derived from the experimental data. The model simulated the individual growth of the dry weight and of the shell converted into energy during the 6 months of the experiment. The results fitted well with the observations until the loss of energy due to the spawning. After that period the model overestimated the growth which was explained by another spawning loss not taken into account in the model and not noticeable with the...

A quantitative approach based on sampling theory and experiment design was used to evaluate configurations of satellite borne altimeters. A simple 2D representation of the experiment design problem, retaining most of the major design issues was implemented. Two different oceanic regions - a large/slow (equatorial Pacific) and a small/fast (Atlantic mid-latitude) region - were selected. The sampling characteristics of configurations of two or three altimeters - all constrained to be of the Topex/Poseidon (T/P) type - vis a vis the two regions were investigated under changes in phase angle between the orbital planes of the altimeters. The preferred arrangement for two T/P altimeters is a separation of 180-degrees. This arrangement simultaneously samples the...

Correlation essais-calcul pour materiaux composites en application marine
Provedor de dados: 5
Autores: Choqueuse, Dominique; Davies, Peter; Bigourdan, Benoit.
The use of finite element calculations is valuable in the design of composite structures, but few examples of correlations between measured behaviour and finite element calculations are currently available. After definition of a representative type of structure (a stiffened sandwich boat hull), and construction of a test set-up allowing the loading of such panels (uniform pressure loading of 1 m by 2 m panels), modelling was performed in four laboratories using different finite element codes. The results obtained (deflections and strains) have been correlated with test results. A satisfactory correlation is obtained for deflections (differences around 20% for the central deflection) but the correlation between measured and calculated strains is less...

Superstructures en matériaux composites
Provedor de dados: 5
Autores: Lelan, J; Parneix, P; Gueguen, P.
Composite materials offer many advantages for the construction of metal hull ships' superstructures (lower weight, higher resistance to fire compared to aluminium alloy, integration of specific functions to the material ...). DCN Lorient has the most of these characteristics to build the "La Fayette" class frigate superstructures. This paper discusses the developments that were undertaken for the choice and validation of the technical solutions retained and particularly the connection to a metal hull. The difficulties to be resolved during the manufacturing and assembly of the superstructures on board the prototype are also discussed. This concept can be applied to other types of ships with metal hulls, by adapting the technological choices to the design...

Monoclonal antibody against a gill Rickettsiales-like organism of Pecten maximus (Bivalvia): application to indirect immunofluorescence diagnosis
Provedor de dados: 5
Autores: Le Gall, Guillaume; Mourton, Chantal; Boulo, Viviane; Paolucci, Francis; Pau, B; Mialhe, Eric.
Using hybridoma technology, monoclonal antibodies (MABs) were prepared against a Rickettsiales-like organism (RLO) from the gills of the Saint-Jacques scallop Pecten maximus. The 5D7 MAB was then selected as a specific reagent suitable for an indirect immunofluorescence assay (IIFA) and evaluated for RLO diagnosis on P. maximus gill smears. Monoclonal antibody 5D7 showed no cross-reactivity with an RLO associated with a related pectinid species Chlamys opercularis.

Monosaccharide composition of suspended particles from the bay of bengal
Provedor de dados: 5
Autores: Bhosle, Nb; Sankaran, Pd; Wagh, Ab.
Neutral carbohydrates were determined as alditol acetates by capillary gas chromatography in the hydrolysates of suspended particulate samples (40) collected from 8 depths (approximately 1 to 1,000 m) at 5 stations of the Bay of Bengal. Eight individual sugars viz. rhamnose, fucose, ribose, arabinose, xylose, mannose, galactose and glucose were identified in the hydrolysates of suspended particulate samples. Amongst these, glucose, mannose and galactose were the most abundant monosaccharides. Rhamnose, fucose, ribose, arabinose and xylose showed large variations and were generally abundant at greater depths (&gt; 100 m). Glucose contribution to the total carbohydrates, especially at higher depths (&gt; 100 m) was relatively less than that reported from...

Resultats d'une intervention sur une parasitose a Proctoeces maculatus (Trematoda, Digenea) affectant la mytiliculture de l'ouest Cotentin
Provedor de dados: 5
Autores: Lebreton, J; Lubert, P.
In 1983, the parasitism of Mytilus edulis L. by Proctoeces maculatus (Loose, 1901) Odhner, 1911 (Trematoda, Digenea, Fellodistomatidae), was recorded for the first time by the authors from mussels farming on stakes (Western Cotentin). After analysing the distribution of the prevalence on the shore and bibliographical data, it was suggested that this parasite must follow a biological cycle that had never been observed on the French coasts and that the most probable host of eggs producer - adult or progenetic metacercaria - would not be a fish but the Prosobranch Gasteropod Nucella lapillus . This was confirmed in 1987. This discovery enabled the authors to support a campaign of eradication of this mussels predatory mollusc. In 1990, the parasitism has...

Recherche de defauts de collage dans les structures sandwich
Provedor de dados: 5
Autores: Darold, L; Blanco, E.
One of the major defects that can be found on composite sandwich structures is poor bonding of the core on the exterior skins, particularly with the technique of bonding under vacuum. Therefore, we have looked at all the possible means of detecting these bonding defects, with two objectives: to be able to control integrally a piece of large dimensions, and to be able to control the piece in the course of manufacturing, that is to say after the bonding on the first skin. All of the non-destructive test methods now known have therefore been tested, and in particularly infrared thermography, ultrasonic control, and acoustic methods. This study, carried out in collaboration with the CETIM, the STCAN, Aerospatiale and other laboratories and companies without...

Large-scales recirculations systems for storage of imported bivalves as a means to counteract introduction of cysts of toxic dinoflagellates in the coastal waters of the Netherlands
Provedor de dados: 5
Autores: Dijkema, R.
In the coastal waters of the Netherlands and in the German and Danish Wadden Sea, at present no PSP-producing toxic dinoflagellate blooms occur. This is in contrast with the situation in a number of countries from which Dutch traders import mussels (Mytilus edulis) and oysters (Ostrea edulis). Especially bulk imports of mussels entail a risk of the introduction of cysts of toxic dinoflagellate species. These can be present within the bivalves but, when dredged mussels are concerned, particularly in accompanying mud and sand. Such cysts can be released into the coastal waters when the imported bivalves are kept in open storage basins or relaid on plots on the sea bottom. To prevent introduction, a ban is in vigour on the immersion into Dutch coastal waters...

Les problèmes d'eutrophisation littorale et leur modélisation
Provedor de dados: 5
Autores: Menesguen, Alain.
Following lakes and rivers, a lot of estuaries (during the last twenty years) and shallow coastal zones (during the last decade) have been severely eutrophicated because of the too much increasing loads of nitrogen and phsophorus. In situ stutdy and numerical modelling of two french case studies bring some explanation to the facts that, in some sites, enrichment turns into green macroalgal proliferation whereas, in others, mass blooms of phytoplankton are induced. Whatever the case may be, the prominent role of the residence time of water in the enriched zone has been proven. In open coastal ecosystems, the difficulty in determining this residence time as well as the limiting factor (nitrogen, or phosphorus, or light) lowers considerably the reliability of...

Évaluation statistique de la répartition des métaux en traces Cd, Pb, Cu, Zn et Mn dans le Seine et son estuaire
Provedor de dados: 5
Autores: Ouddane, B; Fischer, Jc; Wartel, M.
Manganese, copper, zinc, cadmium and lead concentrations were determined in particulate and dissolved phases in the Seine river and its estuary. This site is characterized by macrotidal system, large-scale chemical industrial activities causing contamination of the river system, and by a turbidity maximum in the estuary. Statistical treatment involving principal component analysis of data has shown a marked difference in the behaviour of each metal in solution and suspended material. This phenomenon is related to variations in granulometric profiles, salinity, concentration of different ligands, and amounts of suspended material.... In solution, the behaviour of cadmium and lead is partly related to the gradient of salinity, while that of copper strongly...

Autores: Goslin, J; Aslanian, Daniel.
Altimetry data from repetitive orbits of the GEOSAT satellite are interpreted together with sea-floor depths over the Mid-Atlantic Ridge, South of Iceland and South of the Azores. Geoid / Topography ratios indicate a strong asymmetry of the upper mantle structure in oceanic areas created since 35 My, extending several hundreds kilometers from Iceland to the Azores. A model including interaction between the MAR and two layers of mantle convection seems adequate to produce the observed asymmetry.

The fate of trace metals in the environment and their impact have been a major concern for more than 20 years. Most previous studies have been limited to total metal determination. in general organometallic forms of metals are much more toxic than their inorganic counterparts. Today, the linking of gas or liquid separation techniques with atomic spectrometry detectors will help improve our understanding of the intricate and critical cycles of organometallic forms of metals and metalloids throughout the environment.

In light of the diminishing wetlands, collective management of these natural areas is becoming a major issue in many countries, particularly in Europe. As a multi-use space, wetlands are coastal areas that are, in practice, subject to conflicts of use among various categories of stakeholders who all consider this natural heritage in terms of their own, and sometimes contradictory, purposes. These conflicts of use can be mediated in several ways. First, wetlands depend on a complex decision process that must integrate diverse rationales. Economic rationales when commercial activities compete; social and political rationales, because natural areas, particularly coastal areas where the human population is particularly dense, are subject to regulations issued...

Aquaculture, restocking and stock enhancement as an answer to the scallop fisheries management crisis in the areas of Brest and Saint-Brieuc (Brittany)
Provedor de dados: 5
Autores: Paquotte, Philippe.
Since the beginning of the century, scallop fisheries in France have known successive phases of expansion and recession. Although a system of fishing licences has been implemented, the number of fishermen involved in the scallop fishery has increased and huge investments have been  made. The important fishing effortduring this period has induced a serions stock depletion, and output has dropped to less than 2 000 m.t. per year since 1986. Hence, the remunerations of capital and labour have dramatically decreased. As early as 1973, attempts have been made to use aquaculture methods for the management of  thisstock, following the successful Japanese model. Because of insufficient amounts of spat available from the wild, hatchery and nursery techniques have...

Autores: Dremiere, Pierre-yves; Burgaud, Laurence.
On the French Mediterranean coasts, trawl fishing used to be practiced exclusively with two-sided nets until the middle of the 1970s. The adoption of four-sided trawls has changed the composition of species and sizes of the trawlers'catches in this area. Experimental fisheries conducted in the Gulf of Lion on board a research vessel belonging to the IFREMER enabled the study of the selectivity parameters of a four-sided bottom trawl with a wrapping double-pocket. Three pockets of different meshes were tried out on various demersal and pelagic species. The collected data was processed through different selectivity analysis methods. Presented here is an assessment of the relative efficiency of each of these seven methods.

Provedor de dados: 5
Autores: Gullberg, O.
This paper presents the background to the development of composite materials in marine structures in the Scandinavian countries. The very first vessel constructed in composite materials in 1974 used a special sandwich technique, GRP sandwich, developed in Sweden. Since the the GRP sandwich technique has been the only ship hull construction method used in the Scandinavian countries. The construction method is briefly described, together with the material used. In the second part of the paper examples of the different types of vessels under construction are presented. Finally, in the conclusion some ideas of future development are outlined.

Growth, fatness and gross biochemical  composition of the japanese oyster Crassostrea gigas in stanway cylinders in the bay of Arcachon, France
Provedor de dados: 5
Autores: Robert, Rene; Trut, Gilles; Borel, Michel; Maurer, Daniele.
The Stanway cylinder was tested in the bay of Arcachon from September 1989 to August 1991. Trials were mainly performed on the Japanese oyster Crassostrea gigas in a wind-exposed area. The seed, spat, 18 month old oysters development and fattening of 2 year old oysters were studied. Compared to plastic bags the Stanway cylinder has high positive effects on survival and growth of Crassostrea gigas seed. It also has positive effects on commercial sized Crassostrea gigas fattening. Nevertheless, the cylinder has negative effects on the growth of Crassostrea gigas spat and 18 month old oysters, except for width. However, oyster quality is greatly improve : higher condition index, higher carbohydrate contents and higher shell densities were recorded. Because...

Hepatic EROD activity in dab Limanda limanda in the German Bight using an improved plate-reader method
Provedor de dados: 5
Autores: Eggens, M; Galgani, Francois; Klungsoyr, J; Everts, J.
During the Bremerhaven Workshop an improved, fast and easy method for the determination of ethoxyresorufin-O-deethylase (EROD) activity in dab Limanda limanda liver was tested. The improvement involved the use of a 12500 x g supernatant instead of the microsomal fraction, thus omitting the need for long ultra-centrifugations which cannot be carried out aboard a research vessel. EROD activities in the 12 500 x g supernatant and in the microsomal suspension were well correlated. Despite its disadvantages of lower specific EROD activity, higher minimum detection limit and higher analytical variance, the 12 500 x g supernatant was used for further analysis. EROD activity in dab liver showed a spatial trend corresponding to a pollution gradient in the German...

To meet the demand of the Region Languedoc-RoussiIlon for developing the culture of the european flat oyster Ostrea edulis as a diversification of traditional and off-shore bivalve molluscs cultivation techniques, a first series of experiments on the remote-setting of this species was conducted at the IFREMER Station of Palavas. The objective was to adapt this technique, mainly utilized with the cupped oyster Crassoslrea gigas, to the flat oyster in the Mediterraean conditions, and to assess the growtfi performances of the spats and juveniles supplied through this method. The trials concerned the production of pediveligers, the settlement in controlled conditions, the nursery and pre-growing stages performed on off-shore culture bottom containers, yielding...

Les rendements par espèce de la pêche chalutière hauturière française de l'Atlantique Nord-Est entre 1972 et 1989
Provedor de dados: 5
Autores: Bertignac, Michel.
Multiple correspondance analysis and hierarchical ascending classification were used to study catch rate variations in the French deep-sea trawler fleet between 1972 and 1989. The use of these methods clarifies the sometimes complex relationships between catch rates of the main species landed within the total catch and allows a classification of the typical catch rate structures over this period. Factors such as year and fishing areas are those which best explain the observed variations; seasonal variations play a minor role. Catch rates increased and more species were caught between 1972 and 1989. The study shows the relationship between these developments and changes in fishing effort allocation strategies and in fleet structure. Trawlers which exploited...

La qualite du controle par ultra-sons des materiaux composites utilises en construction navale
Provedor de dados: 5
Autores: Lehire, J; Cancre, F.
Ultrasonic non-destructive testing is frequently used for composite materials. Concerning shipbuilding materials, the observation of the echograms reveals significant acoustic noise which impairs the detection of defects. The usual practice of analysing individual echograms is therefore inadequate. A method based on the intercorrelation function has therefore been developed and tested. The results should allow a classification of materials based on a criterion of the quality expected for each material.

Evaluation of oyster sampling efficiency of patent tongs and an oyster dredge
Provedor de dados: 5
Autores: Chai, Ai-ling; Homer, Mark; Tsai, Chu-fa; Goulletquer, Philippe.
Sampling efficiency of two oyster fishing gears, patent tongs and an oyster dredge, were compared in reference to diver-harvested quadrats in Chesapeake Bay, which supports important harvests of eastern oyster Crassosrrea virginica. Mean densities of spat (0$35 mm), small oysters (&gt;35 mm to 75 mm), marketable oysters (&gt;75 mm), and all oysters (three size-groups combined) estimated from patent tong samples were not significantly different from those derived from diver-harvested quadrat samples. In contrast, the densities estimated from dredge samples were low, only 2-32% of the diver estimates. Accordingly, patent tongs are recommended as the sampling gear for estimating eastern oyster stock abundance in the Maryland portion of Chesapeake Bay.

Autores: Raymond, N; Bonin, P; Bertrand, Jc.
Different types of denitrification rates in coastal marine sediments from the Western Mediterranean coast (France) were simultaneously determined by varioUS C2H2 inhibition techniques: in situ denitrifying activity in intact cores or sediment slurries; DEA (Denitrifying Enzyme Assays); and potential activity. Denitrifying activity was also estimated by the use of kinetic parameters (Km and V(max)). Values for denitrifying activities in the top two centimetres ranged from 0 to 50-mu-moles of nitrous oxide produced per litre of sediment per day, and were similar when intact core or sediment slurries were used. DEA showed comparable values for all the study sites. The potential activity ranged from 298-600-mu-moles per litre per day. Estimated activity based...

On altimetric data assimilation experiments in a linear-model of the tropical atlantic-ocean
Provedor de dados: 5
Autores: Bourles, B; Arnault, S; Provost, C.
We present results of sequential data assimilation of altimetric data in a linear tropical Atlantic model, using an analysis technique that we have developed. We use sea level anomaly fields obtained from altimetric data of the satellite Geosat. Despite the weak amplitudes of the anomaly fields, we obtain marked improvements of the model simulations due to assimilations. Thus, we show that altimetric data may be very useful for improving model simulations when adapted assimilation techniques are applied.

La densite, un critere de qualite applicable en ecloserie aux embryos de Pecten maximus (mollusque bivalve)
Provedor de dados: 5
Autores: Faure, Catherine; Devauchelle, Nicole; Dorange, Germaine.
The quality of the scallop embryos is determined by the spawners characteristics as well as by the external factors they support during the maturation and the spawning phases. All these parameters are not still well controlled during the artificial conditioning in the hatcheries. As a consequence, the quality of the embryos is drastically variable and with them, the larvae performances in terms of survival and growth rates. It would be interesting to get a simple and quick test which would allow the estimation of the spawns quality. The embryos density, evaluated by isopycnic centrifugation of Percoll medium, is well adapted to this objective. Actually, a centrifugation of embryos two hours after fertilization separates them in 3 stratum with their density...

Comme les ondes électromagnétiques en télédétection spatiale (micro-ondes, Visibles, Infra-Rouge ou Radio), les ondes sonores sont utilisées pour la détection, l'identification de cibles, ou pour les transmissions dans le milieu marin. Mais les problèmes rencontrés en propagation dans le milieu marin sont multiples et très pénalisants : le milieu est inhomogène, diffusant, dissipatif, borné et très bruyant. Toutes ces conditions nuisent à la bonne propagation des ondes acoustiques dans la mer ; néanmoins, seuls les signaux acoustiques sont capables de fournir rapidement et dans toutes les configurations des informations sur les caractéristiques des fonds. Les analogies entre la télédétection micro-onde (RADAR) et la "télédétection sousmarine" sont...

Application of multiaxial reinforcements in the marine industry.
Provedor de dados: 5
Autores: Taby, J; Hoyning, B.
Knitted multiaxial reinforcement are today more and more commonly used in the production of marine vessels. This is due to superior strength compared to traditional reinforcements such as woven roving and chopped strand mat. Strength properties in different resins are documented, and multiaxial and woven reinforcements are compared. Special attention is paid to interlaminar properties, and it is apparent that no intermediate layers of chopped strand mat are necessary when using multiaxial reinforcement. Methods of analysis are discussed, the influence of fibre orientation on strength and stiffness of structures is described, and a case study reveals considerable weight and cost saving potential.

Autores: Davies, R; Ritchie, M; Trumper, R.
Metal matrix composites (MMC) offer a unique combination of properties that make this class of material ideally suited to the fabrication of components subjected to complex loads, such as marine structures. In many marine applications the dominant requirement is for a reduction in structural weight, and where failure occurs by elastic buckling stiffness is critical. MMC's encompass a very broad class of materials which may be subdivided into three main groups: particulate, whisker and continuous fibre reinforced metals. These materials offer improvements in stiffness and the strength to weight ratio over conventional alloys. However, the ability to construct efficient marine structures is constrained by the ability to join these materials both to...

The treatment of certain cases of corrosion in living environments involves the consideration of two quite different disciplines, namely biology and corrosion. Either one or the other will be preponderant, according to the problem and the circumstances, and the two aspects are not necessarily permanently interdependent. Since the difficulties inherent in any multidisciplinary research are particularly pronounced for two such disparate fields, training and information exchange are of paramount importance. The need to harmonize terminology and concepts signifies, for the biologists, the use of a more chemically precise vocabulary and the abandonment of certain outdated theories, such as the notion of "cathodic depolarization", which are incompatible with...

Autores: Mikula, Stéphane.
Le séchage ou dessiccation consiste à évacuer l'eau d'un matériau humide vers le milieu ambiant dans le but d'en assurer la stabilité. Actuellement, le séchage à l'air chaud est le mode de déshydratation le plus employé dans le monde pour le traitement des denrées alimentaires. Cependant, cette technique présente quelques inconvénients. Au cours du séchage, il se produit généralement un gradient de déshydratation aboutissant à un dessèchement superficiel caractérisé par un croûtage et un temps de traitement important. Il existe de nombreuses techniques de séchage. On distingue les techniques traditionnelles encore utilisées dans de nombreuses régions du globe qui associe le soleil et l'air.

Evolution of glass fibre-resin composites (polyester, epoxy and vinylester) after 30 years in a marine environment has been anticipated by the compilation of the Naval Construction Direction test results. This study showed that 120 degree C epoxy prepreg, in spite of improved initial performance, was more affected by water environment aging than other composites. Post-curing of epoxy and vinylester composites does not significantly improve resistance to water degradation except in the case of high temperature aging (60-70 degree C).

The objective of this study is to understand the influence on larval transport of the different hydrodynamic factors present in the English Channel. A population of annelid polychaetes, Pectinaria koreni, and a site, the Seine Bay, were chosen as being particularly appropriate for such a study. Different patterns of larval transport were observed during an intensive sampling season in 1987. The first pattern corresponds to the average residual transport which is dominated by tide: larvae are mainly transported northward. and a larval retention exists near the mouth of the estuary due to the interaction between the vertical current structure and the vertical distribution of larvae. The other patterns are wind-driven. Larvae are transported northward with...

In England and Wales purification tanks are built to comply with broad operating criteria specified by the Ministry of Agriculture Fisheries and Food. These have been developed over many years with limited availability of data and has resulted in design restrictions which have limited the economic viability and effectiveness of the tanks. The approved method for the large scale purification of mussels has been to spread them in a single shallow layer in large outdoor tanks with access to a supply of clean sea water. This results in a purification plant that requires a lot of land, is labour intensive and generally remote from the harvesting area. In addition such tanks are exposed to ambient conditions and can result in filtration activity, upon which...

Autores: Desbruyeres, Daniel.
Créé en 1986 au sein de la direction des recherches océaniques, le département Environnement profond se veut l'héritier d'une longue tradition française et monégasque d'étude de la biologie des organismes abyssaux, avec un triple objectif : explorer et décrire la structure et le fonctionnement du plus grand écosystème de la planète qui reste pratiquement inconnu, acquérir les connaissances permettant de gérer et de protéger un environnement fragile, exploiter, non la biomasse, mais la diversité biologique de ce milieu.

Essais de decontamination des huitres Crassostrea gigas en bassin par renouvellement et circulation de l''eau
Provedor de dados: 5
Autores: Faury, Nicole; Masson, Daniel; Ratiskol, Jacqueline.
The germs decreasing of artificially contaminated oysters Crassostrea gigas has been studied in experimental tanks similar to a shellfish depuration plant, without any chemical or physical water treatment. The oyster were treated by three different water management pattern, compared to a control tank and the germs decreasing studied by MPN method of fecal Coliforms and Streptococus. As a result: 1) it appaears somewhat difficult to conclude in this first attempt about the most efficient treatment. 2) the most important factor in shellfish depuration working is obviously the physiological activity (and stage) of the animals.

Etude des hémocytes et d'une néoplasie hémocytaire chez les moules Mytilus edulis et Mytilus trossulus (Mollusca, Bivalvia)
Provedor de dados: 5
Autores: Noel, Danièle.
La transmissibilité d'une néoplasie hémocytaire de moules M. trossulus du Puget Sound, Etat de Washington (USA) à des moules M. edulis a été montrée bien que la prévalence semble faible. L'étiologie n'a cependant pas pu être déterminée.  La caractérisation antigénique des hémocytes normaux de M. edulis et des hémocytes néoplasiques de M. trossulus, a été réalisée à l'aide d'anticorps monoclonaux (AcMs). Quatre classes d'AcMs spécifiques des hémocytes normaux ont été obtenus. L'AcM de classe I reconnaît spécifiquement les granulocytes basophiles alors que les autres classes d'anticorps réagissent avec les deux types de granulocytes. Les AcMs de classe IV semblent associés à la différenciation des granulocytes. Les AcMs spécifiques des hémocytes néoplasiques...

Rythmes à court et à moyen termes associés au broutage de la microflore marine épilithique par Littorina saxatilis
Provedor de dados: 5
Autores: Konan, A; Cardinal, A; Lamontagne, I.
The temporal variations of the grazing rate of a marine herbivorous gastropod, Littorina saxatilis, were measured in laboratory conditions. In a first series of measurements, the natural circadian and tidal cycles were preserved. Samplings were performed at intervals of 2 h over a period of 8 d. In a second series of experiments, during two three-day periods, the natural circadian or tidal cycles were reversed. The available resource for the herbivores was obtained from artificial substrata previously colonized by intertidal microflora at the same tidal level as that where L. saxatilis was found. This algal assemblage was principally composed of pennate diatoms, Achnanthes groenlandica and Fragilaria striatula being the most common. The grazing rate was...

Autores: Castaing, Philippe.
Les matériaux composites à matrice polymère et renfort minéral, revêtus de gelcoat (résine pigmentée de protection), sont largement utilisés en construction nautique, ou pour diverses applications courantes comme les canalisations, réservoirs, piscines et carrosseries. Cependant ces matériaux composites verre/polyester résistent de façon inégale au vieillissement climatique (humidité de l'air, rayonnement ultraviolet et immersion en eau de mer). En particulier, un endommagement d'origine osmotique conduisant à un délaminage du revêtement (apparition de cloques circulaires) et du stratifié (défauts de forme quasi-ellipsoïdale) à plus long terme a été identifié. L'étude entreprise à l'IFREMER qui fait l'objet de cette thèse, traite de l'influence de divers...

Isolation and characterization of a pathogenic bacterium specific to Manila clam Tapes philippinarum larvae
Provedor de dados: 5
Autores: Nicolas, Jean-louis; Ansquer, Dominique; Cochard, Jean-claude.
A bacterial strain belonging to the genus Vibrio was involved in a recurrent outbreak of disease in Manila clam Tapes philippinarum larvae at a commercial hatchery, This vibrio, named VTP for convenience, was not related to the known pathogenic vibrios and possessed unusual characteristics, Only Manila clam larvae and postlarvae were affected by the disease, Oyster and scallop larvae were not affected by vrp, Survival of vrp was found to be of short duration in seawater but even a very small number of cells (1 cell per 5 ml) could initiate the disease, VTP did not grow on thiosulfate-citratebile-sucrose agar and was resistant to chloramphenicol. An epidemiological study utilizing bioassays revealed the presence of VTP in adult bivalves and in the...

Autores: Antona, Martine; Pitiot, H.
Trends in french household consumption are globally analysed and studied over the eighties. Household consumption is described according to its main components (fresh, deep - frozen, processed, non - processed fish or others sea products). The diverging changes in household consumption at home (products, species) and in the catering sector is stressed. With these informations, we consider the historical sea product consumption as a component of the consumption behaviour which finally expands among industrial countries. Sea food consumption evolution patterns are linked to household socio - demographic criteria (socio- professional groups, urban or rural localisation, region, age of the head of household, family size) and not only to economic criteria such...

Évaluation, par télédétection satellitaire, des stocks de Macrocystis pyrifera dans le golfe du Morbihan (archipel de Kerguelen)
Provedor de dados: 5
Autores: Belsher, T; Mouchot, Mc.
Macrocystis pyrifera, algae which grow to about 60 m in length, are widely present in the Kerguelen Islands. A satellite program has been initiated to map these species quantitatively and qualitatively as well as to establish a possible correlation between their occurrence and sea- surface temperature. Data from SPOT-1 and NOAA-11 AVHRR were acquired during the 1988 austral summer around the area of "l'ile Noire". SPOT-1 data processing has permitted estimation of the biomass (wet weight) of Macrocystis pyrifera at 1 106 kt, spread over an area of 186.30 km2 in the Morbihan Gulf. Supervised classification shows that 30 % of the vegetal coverage carries 60 % of the total biomass. These clusters of seaweed represent a potential of 13 220 tons of...

Viral contamination and depuration of oysters under field conditions
Provedor de dados: 5
Autores: Boher, S; Piclet, Guy; Beril-stien, S; Masson, Daniel; Delonce, R; Biziagos, E; Schwartzbrod, L.
Shellfish consumption is clearly associated with the transmission of enteric viruses. The channel of transmission of enteric viruses to human beings could be decreased particularly if the systems of depuration of shellfish were optimized, standardized and if their viral efficiency was controlled. The purpose of this work was to study the contamination of oysters and to assess the efficiency of several depuration processes. Our study have demonstrated that in some cases, 50% of oysters samples contain enteric viruses or H.A.V. antigen and the quantities of viruses range from 17 to 246 FF for the rotaviruses and from 124 to 200 for the enteroviruses per 100 g of tissue. According to our results, the exclusive use of a bacteriological criterium to determine...

Données économiques sur la conchyliculture française
Provedor de dados: 5
Autores: Antona, Martine.
15% of the shellfish production in France comes from natural deposits and the other 85% from farming. Years 1980-1990 showed a slight decrease in the shellfish production then a resurgence from 1985 onwards, an increase in the oyster production and a strong decrease in mussel production at the beginning of the 1980's followed by a resurgence due to the increase of open sea activity. In France, the shellfish market represents 300,000 tons, divided between oysters (40%), mussels (30%) and scallops (15%). Importations of mussels and scallops in order to supply the domestic market are important. On the other hand, external trade flows are very low as far as oysters are concerned: France is the only important market for oysters in Europe. (unverified OCR)

Autores: Morel, M; Salamon, W.
European regulations (Directive EEC/15.07.91) provide that marketing of live bivalve molluscs intended for human consumption must comply with strict bacteriological criteria. In order to comply with these requirements along the Nord/Pas de Calais coast and to preserve shellfish culture activities, a transfer through a depuration plant is the only solution at the present time. IFREMER, with the support of the Nord/Pas-de-Calais regional authorities, conducted an initial study on the use of UV for mussel depuration and on the design of a shellfish depuration plant. This study was used as a basis by TECHMAR Company to design a project for a modular type plant, under contract from the Nord/Pas-de-Calais Region. The basic module consists of two ponds with a...

Composite materials represent for shipbuilding industries a possible way to improve the competitiveness of products, particularly in the field of high technology vessels where high strength and stiffness to weight ratios allow increased payload capacity to be obtained, improved performances and lower propulsion costs. In fact with these materials the designer can obtain considerable saving in structural weights, easier production and assembly techniques for complex shapes structures, and better long term performances of the structures when exposed to the marine environment. Unfortunately potentially wide application of F.R.P. structures is restrained by a general lack of knowledge on the mechanical and physical behaviour of these structures. In this...

Interactions Between Dissolved Organic Matter and Organic Contaminants
Provedor de dados: 5
Autores: Tronczynski, Jacek.
The interactions between dissolved organic matter and organic contaminants affect their solution speciation and their distribution between the aqueous and solid phases. This partitioning governs the transport and influences the transformations and toxicity of contaminants. Thus, detailed understanding of fate and effects of contaminant in aquatic ecosystems is dependent upon the knowledge of contaminant speciation in these environments.

Relation between th-234 scavenging and zooplankton biomass in mediterranean surface waters
Provedor de dados: 5
Autores: Schmidt, S; Nival, P; Reyss, Jl; Baker, M; Buatmenard, P.
Dissolved and particulate Th-234 activities were determined and phyto- and zooplankton biomass were periodically measured 8 miles off Nice (Mediterranean Sea) during spring 1987. The results show a strong variability of Th-234 distribution on short time scales in northwestern Mediterranean surface waters. The good correlation observed between the zooplankton biomass and the rate of Th-234 export to deep water in particulate form is in agreement with the assumption that the residence time of particulate Th-234 in oceanic surface waters is controlled by zooplankton grazing. Moreover, our results indicate the importance of salps in particular as efficient removers of small suspended particles in surface waters.

The behaviour of F specific bacteriophage in depurating shellfish with reference to their use as pollution indicator organisms
Provedor de dados: 5
Autores: Lees, D; Dore, W.
The behaviour of sex-pilli specific (F+) bacteriophage during the depuration process was investigated using Pacific oysters (Crassostrea gigas) and edible mussels (Mytilus edulis) naturally contaminated with untreated sewage. F+ bacteriophage was eliminated considerably slower than E. coli. This effect was most pronounced in oysters which showed average T90 bacteriophage values of 62.5 hours compared with 11 hours for E. coli. F+ bacteriophage in mussels was largely confined to the digestive tract. The majority of E. coli were similarly located but, in contrast, counts were also distributed throughout the other internal tissues. Investigation of ultra-violet (UV) dosage showed that the difference in depuration rate was unlikely to be due to the higher...

Assimilation of geosat data into a quasi-geostrophic model of the north-atlantic between 20-degrees and 50-degrees-N - preliminary-results
Provedor de dados: 5
Autores: Verron, J; Molines, Jm; Blayo, E.
Geosat altimeter residuals of the sea surface height (RSSH) are combined with the mean sea surface computed from the non-linear inverse model by Mercier et al. (1991) to provide a synthetic data set of the along-track sea-surface height over the North Atlantic during the period from 5 November 1986 to 2 December 1987. This data set is assimilated into a predictive numerical model of the North Atlantic circulations between 20-degrees and 50-degrees-N. The model is quasigeostrophic, four-layered and has realistic coastline and topography. The ocean circulation is forced by a constant wind stress curl from Hellerman and Rosenstein's data (1983). Nudging is the assimilation technique used to insert sea-surface data information into the model and is carried out...

Data from twenty consecutive cruises, carried out over a period of five years, were investigated in order to reveal temporal changes in the characteristics of the AW (Atlantic Waters) and the LIW (Levantine Intermediate Waters) in the Southeastern Levantine basin. The results indicated a seasonal trend in the AW, which appear to be poorly defined during winter and spring but which, as the year progresses and as the LSW (Levantine Surface Waters) form and penetrate downward, become better defined, and occupy a narrower layer whose depth increases. There appeared to be no season related variations in the LIW. Moreover, abrupt, significant, and apparently irreversible changes in the characteristic salinity of the AW and the LIW occurred in the Southeastern...

In 1989 and 1990, the Brittany Region has conceded a subvention to the shellfish professional organisation, for a study on the sea star proliferation Asterias rubens ; this species is a predator of reared oysters in subtidal zone, specially in the Bay of Quiberon (South Brittany). The sea star species Luidia ciliaris has been identified as an A. rubens predator in laboratory. In presence of A. rubens and various molluscs species, the exclusive prey L. ciliaris is A. rubens . Even deprived of A. rubens they do not eat any bivalve. The first result led us to set up an introduction test of L. ciliaris as the main predator of A. rubens and their relative spatial stability. In prospect of mass introduction of L. ciliaris in the bay, reproduction experiments...

Two different biomasses (100 g multiplied by m super(-2) and 1 kg multiplied by m super(-2)) of oysters were put in identical sea-water ponds, thus leading to different trophic conditions, corresponding to rearing techniques. Changes in growth, biochemical composition and sexual maturation were recorded for two age groups. The first one included 9 month-old oysters and the second one 21 month-old oysters, at the beginning of the experiment. For both age groups, significant differences were observed in growth and biochemical composition. Lipids were accumulated faster for the lower biomass. However, the only difference concerning glycogen was observed on the older oysters. They showed a peak at the lowest biomass and a decrease at the larger biomass. Sexual...

Les rotavirus font partie des principaux virus entériques humains susceptibles d'être rencontrés dans l'environnement. Leur mise en évidence par culture cellulaire dans des prélèvements est longue et peu sensible, ce qui explique le manque de données sur la contamination du littoral. La RT-seminested PCR a été développée pour pallier ces inconvénients. Après une mise au point méthodologique cette technique a été utilisée lors d'études in vitro et in situ. Les études in vitro sur le devenir des rotavirus en eau de mer, suivi par RT-PCR quantitative et par multiplication en culture cellulaire, montrent que dans des conditions proches de celles du milieu naturel (eau de mer non stérile et à une température relativement basse), la détection d'ARN viral peut...

The repetitive and expanding occurrence of a green, bloom-forming dinoflagellate (Dinophyceae) on the coasts of France
Provedor de dados: 5
Autores: Sournia, Alain; Belin, Catherine; Billard, Chantal; Catherine, Martial; Erard-le Denn, Evelyne; Fresnel, Jacqueline; Lassus, Patrick; Pastoureaud, Annie; Soulard, René.
A dinoflagellate has produced green-water events along the Atlantic and English Channel coasts of France since 1982. It differs morphologically from each of the 12 taxa or so of green gymnodinoid dinoflagellates previously known. As some morphological details, as well as their variability, remain to be ascertained, this organism is illustrated and described here under the provisional designation of Gymnodinium "sp. 1982". The presence of chlorophyll b has been confirmed by HPLC analysis but it could not be ascertained whether true chloroplasts are present, or symbionts. The distribution is coastal and estuarine. The number and intensity of the outbreaks may be related to river runoff and to the amount of preceding rainfall. An encysted stage is described....

La gestion des pêches en Méditerranée : problématique pour une articulation des programmes de recherche
Provedor de dados: 5
Autores: Rey, Hélène.
La définition d'un programme de recherche répond à une question posée issue quelques fois de recherches antérieures. Ici, l'objectif qui nous est assigné est différent. L'objet de recherche est connu: il s'agit de la gestion des pêches. La réflexion se situe en amont des programmes puisqu'il nous est  demandé d'identifier des questions de recherche permettant une approche coordonnée tant entre les pays qu'entre les disciplines. La mise en place prochaine d'une politique commune en Méditerranée nécessite que cette réflexion dépasse les questions d'efficacité des outils en s'interrogeant sur la cohérence générale d'une politique de régulation de la pêche dans cette zone. Les spécificités des pêcheries méditerranéennes alliées au constat récent d'inefficacité...

Monoclonal antibody against a gill Rickettsiales-like organism of Pecten maxiumus (Bivalvia): application to indirect immunofluorescence diagnosis
Provedor de dados: 5
Autores: Le Gall, Gyslaine; Mourton, Chantal; Boulo, Viviane; Paolucci, Francis; Pau, Bernard; Mialhe, Eric.
Using hybridoma technology, monoclonal antibodies (MABs) were prepared against a Rickettsiales-like organism (RLO) from the gills of the Saint-Jacques scallop Pecten maximus. The 5D7 MAB was then selected as a specific reagent suitable for an indirect immunofluorescence assay (IIFA) and evaluated for RLO diagnosis on P. maxiumus gill smears. Monoclonal antibody 5D7 showed no cross-reactivity with an RLO associated with a related pectinid species Chlamys opercularis

The use of ozone to degrade Gymnodinium breve toxins
Provedor de dados: 5
Autores: Schneider, K; Rodrick, G.
Gymnodinium breve toxins were exposed to ozone treatment in both extracted form and in intact whole cells. Samples displayed a three log reduction in the total amount for toxin (PbTx-1, -2, -3, -5, -7 and -9) recovered after ten minutes as determined by HPLC analysis. Ozone effectively killed the red tide dinoflagellates when directly contacted ozone and when exposed in a pre-ozonated ASW environment. Both samples, when examined by light microscopy, displayed little difference between the direct and indirect ozone treatments. Reduction in toxin levels directly correlated with reduction of toxicity as observed using by a fish (prinodon variegatus) bioassay.

Contribution a l'usinage des materiaux composites
Provedor de dados: 5
Autores: Guegan, P; Lemaitre, F; Hamann, J.
While machining is generally to be avoided in the fabrication of components with composite materials, nevertheless many parts require some machining, drilling or milling after moulding. Machining of these materials involves the risk of damage in the machined region. It is therefore important to study the possible sources of damage and to quantify their extent for different drilling and milling operations.

Ecology of idotea-baltica (pallas) populations in the lagoon of venice
Provedor de dados: 5
Autores: Fava, G; Zangaglia, A; Cervelli, M.
A two-year study was carried out on the ecology and dynamics of two Populations of Idotea baltica from the lagoon of Venice. Body size variations were found to follow a seasonal pattern at Romea, the sampling station located in the central part of the lagoon, but not at Toro, the marginal area. The reproductive period extends throughout the year, but the frequency of ovigerous females and the number of eggs in the marsupium are seasonally variable, achieving the maximum in summer. A significant correlation between number of eggs and body size of the female was found. The examined population variables were not affected by the colour morph. Frequency fluctuations of the major colour phenotypes (uniformis and bilineata) were quite variable at the Toro...

Une théorie de plaque sandwich
Provedor de dados: 5
Autores: Mace, M.
The objective of this paper is to present a new two-dimensional plate theory inside which a very thin layer is sandwiched. Based upon a prescribed displacement field and a shear stress field fulfilling continuity conditions at the interfaces, this model takes into account the shearing strain due to the high rigidity ratio between the thick skins and the thin film. It is also shown how the present theory was assessed when calculating a rectangular sandwich plate for which Pagano proposed an "exact" three-dimensional solution.

Sedimentological and biological differences across a deep-sea ridge exposed to advection and accumulation of fine-grained particles
Provedor de dados: 5
Autores: Jensen, P; Rumohr, J; Graf, G.
Large amounts of clay and silt particles from the northem Voring Plateau (Norwegian Sea) accumulate on a ridge (Voring Plateau escarpment) situated at 1 245-1 310 m depth on the northem Voring Plateau. Calculated Holocene sedimentation rates are up to 18 cm ky-1, while amounting to less than 1 cm ky-1 on the slope south of the ridge. Six stations were sampled - three on each side of the ridge - to obtain quantitative information of different biological components and relate these observations to the environmental conditions. Pronounced biological differences between the southern and northem sites are evident in terms of oxygen consumption, meio- and macrofauna composition, meiofauna biomass and meiofauna depth distribution. A specific fauna consisting of...

Regional and interannual variations in biomass and productivity of the marine copepod, calanus-finmarchicus, in sub-arctic environments
Provedor de dados: 5
Autores: Tande, Ks; Slagstad, D.
A model for estimating the productivity of Calanus finmarchicus in subarctic waters is developed based on data on individual growth, developmental rates, feeding, vertical behaviour and population parameters obtained from the same region. In fjords and coastal waters of Northem Norway and in the Barents Sea C. finmarchicus is considered to produce one generation every year. Population data obtained monthly from November 1976 to December 1977 in Balsfjorden, Northem Norway, show that C. finmarchicus reproduces during March and April, and has a quantitatively important growth and production period in May and June. A physiological model is developed to simulate the dynamics of population development and productivity from March to July, and details on...

A rating system for oyster purification. Hazard analysis critical control point (HACCP) application to purification of live oysters
Provedor de dados: 5
Autores: Bird, P.
A Critical Hazard Analysis Rating (CHAR) based on the Hazard Analysis Critical Control Point (HACCP) concept is used to monitor oyster purification in New South Wales (N.S.W.), Australia. Critical areas for assessment include oyster condition, separation of raw and treated oysters, water quality (turbidity, salinity, temperature, aeration, circulation), purification period, flow rate, steriliser efficiency and tank hydraulics. Batch records and product identification are included. Purification supplements a total management program for producing safe oysters. The rating can also be used to endorse oysters produced under industry self-regulatory, quality assurance programs. The four main CHAR areas are operational standards, quality assurance, public health...

Diurnal mesoscale patterns of 50-khz scattering layers across the ligurian sea front (NW mediterranean-sea)
Provedor de dados: 5
Autores: Baussant, T; Ibanez, F; Dallot, S; Etienne, M.
Between March and June 1988, a series of diurnal acoustic records was carried out using a 50 kHz echosounder on a transect crossing the density front of the Ligurian Sea, off Villefranche-sur-Mer (Mediterranean Sea). The depth, thickness and pattern of the sound scattering layers were studied with respect to physical (temperature, salinity and density) and biological (chlorophyll a) measurements made along the acoustic transect. Seasonal differences were observed. A surface scattering layer (SSL), from 0 to 100 m, and a main deep scattering layer (MDSL), located between 250 and 550 m, occurred permanently during the study. In spring, an intermediate scattering layer (ISL), about 50 m thick, occurred between the SSL and the MDSL. The ISL, a permanent...

Inadequacy of bacterial indicators for assessing elimination rates of viruses from molluscan shellfish
Provedor de dados: 5
Autores: Burkhardt, W; Watkins, W; Rippey, S.
The reported incidence of shellfish-borne illness in the United States increased dramatically during the last decade. Most of the outbreaks are attributed to diseases of viral aetiology. These human health problems result primarily from the ingestion of raw shellfish which have accumulated enteric pathogens from environmental waters or from wet storage facilities. Our studies have demonstrated that hard-shelled clams concentrate different indicator micro-organisms at variable and unpredictable rates during the year. In temperate waters, this has been observed at two abbreviated periods in mid-spring and again in late fall when accumulation rates increased dramatically. Moreover, these rates were not generally coincident for viruses and bacteria. In...

Autores: Barnouin, Bruno; Renaud, P.
The main conclusions drawn from examinations made by an expert over the last twelve years on boats in the Bay of Arcachon, including both motor and sailing boats, are presented. The different types of damage most frequently observed in different areas of the boats are described, with distinctions made between superstructures, areas below the water-line and other components. The damage is defined, common repair methods are described and simple design modifications to avoid the problems are discussed. In conclusion, it is apparent that the problems related specifically to aging of the material are rare or very rare. With improved fabrication methods and mastery of the design process in-service experience fully justifies the position of composite materials as...

Essai de caractérisation sous pression de panneaux en composites pour structures marines
Provedor de dados: 5
Autores: Reichard, R.
Traditional testing of FRP sandwich panels using uniaxial loading provides useful data for structural designers, but these tests do not work well for multiaxially reinforced laminates or for sandwich laminates. Sandwich laminates are generally used to increase the flexural properties of a panel. Flexural testing of sandwich beams does not address panel membrane effects, which can be significant. As a result, a number of different methods have been developed for testing panels. Experiments with multiaxial FRP sandwich panels have been conducted to evaluate the behavior of panel laminates with various fiber orientations and core materials under both static pressure loading and hydrodynamic shock loading. The test apparatus and methods are described, and the...

Influence of early thermic and photoperiodic control on growth and smoltification in Atlantic salmon (Salmo salar)
Provedor de dados: 5
Autores: Gaignon, Jean-louis; Quemener, Loic.
Atlantic salmon juveniles were subjected to a precocious (day 104 after first feeding) photoperiodic (P) and thermic (T) control. After rearing the fry at 16 degrees C, constant (16 hours of light and 8 hours of darkness, 16 degrees C) (C) and shortened simulated natural S photoperiod and temperature regimes were used in a factorial experimental design until transfer to seawater. The growth obtained with constant (C) regimes was better than with S regimes. In all cases, we observed very early (day 141, mid-June) a clear segregation of the population into two different subpopulations. Among the conditions, all the differences between the upper and lower modes were growth-dependent. We observed different developmental trends of the gill (Na+-K+)-ATPase...

De la pêche à l'aquaculture : l'élevage de la coquille Saint-Jacques
Provedor de dados: 5
Autores: Fleury, Pierre-gildas; Dao, Jean-claude.
The scallop is a filtering mollusc that feeds predominantly on phytoplankton. It lives on loose beds of maerl, sand or mud, most often between 5 and 40 metres deep. The scallop likes cool (7° to 20°C) and well oxygenated ocean waters. It does not tolerate desalination or emersion out of water. In France, there are two very closely related species: Pecten maximus in the English Channel and the Atlantic and Pecten jacobaeus in the Mediterranean. These are frequent species in French coastal waters. But the many deposits, considerably exploited, have rather thinned out over the last 20 or 30 years.

Evolution des propriétés mécaniques de matériaux composites verre/polyester gelcoates en milieu marin
Provedor de dados: 5
Autores: Castaing, P; Tsouvalis, N; Lemoine, Lionel.
Glass-fiber reinforced polyester composites with gelcoat are widely used in nautical construction despite the lack of knowledge concerning their durability when immersed in water. This study deals especially with the influence of the osmotic process of degradation on the evolution of the mechanical properties of orthotropic materials, subjected to accelerated ageing tests. This evolution is experimentally evaluated by performing a non destructive test procedure, the vibrational modal analysis, whose results are additionally confirmed by quasi-static mechanical tests (bending and shear). Although gelcoat blistering has no effect on the mechanical properties of the structure, considerable changes are observed in the elastic moduli and in the ultimate...

Détermination de l'age du merlu (Merluccius Merluccjus L.). Problèmes d'interprétation des otolithes
Provedor de dados: 5
Autores: Guichet, Roger; Labastie, Jacques.
Since Hickling's studies in 1933, several authors have used otoliths for age determination of hake. The different results show important divergences in reading, which indicate the complexity of otolith structures and the difficulties of interpretation. The otoliths of european hake display many subannular bands which cannot be identified as winter zones. The first winter ring is often hard to locale and the outer edge is difficult to read. The aim of this paper is to review the recent works and to emphasize the difficulties in reading otoliths of hake.

Caractérisation chimique des composés humiques et de leurs diverses classes de poids moléculaires dans les dépôts du delta du Rhône
Provedor de dados: 5
Autores: Gadel, F; Charriere, B; Serve, L; Comellas, L.
The analysis of humic compounds by elemental analysis, PY-GC-MS and HPLC techniques permitted determination of the origin of organic inputs, essentially terrestrial, and the effects of environmental conditions in the deposits along a north-south transect through the Rhone delta, from the river mouth to the open sea. In the prodelta the sedimentation of fine particles enriches the sediments in organic matter. The humic compound contents were relatively low in sediments, perhaps due to a rapid burying of organic matter which leads to anoxic conditions. In sediments fulvic acids are more abundant than humic acids. Elemental analysis indicated that fulvic acids were enriched in hydrogen and nitrogen as compared to humic acids. Furthermore, H/C and N/C ratios...

Autores: Hildebrand, M.
The material properties of over 50 different laminates made by a group of Finnish boat-yards have been measured in a large test project. Tension, compression, bending, interlaminar shear and impact tests have been carried out for all the laminates. Among others, different polyester resins, different woven and non-woven fabrics, chopped strand mat and unidirectional roving were used as basic ply materials. The effect of various parameters has been determined not only on the maximum failure strength, but also on the strain level at which the first failure occurs. Main differences between the ratio of static and impact test results of the different materials have been determined. The results show that by choosing certain material parameters efficiently,...

La construction navale optimisée. Le choix de matériaux d'âme et la fabrication sont étroitement liés
Provedor de dados: 5
Autores: Gellhorn (von), E; Mittelmann, G.
Sandwich panels with a facing of laminated fibre reinforced plastics are now established boatbuilding materials. In the last few years they have begun to replace the traditional metal and wood in ship and marine construction. Today's materials are usually selected on the basis of minimum cost and simplicity of construction. This is often contrary to the demands of the owner who wants an inexpensive, safe, easy-care and long-lasting ship. The requirements of boatbuilder and operator can easily be satisfied if the combination of the best choice of materials and new, rationalized construction methods are considered. Taking the construction of the boat "Sandwich" as an example we will demonstrate the increased importance of the tough rigid linear PVC foam core...

Interpretation of kelvin rossby waves in the equatorial pacific from model-geosat data intercomparison during the 1986-1987 el-nino
Provedor de dados: 5
Autores: Dupenhoat, Y; Delcroix, T; Picaut, J.
Analysis of Geosat sea level data over the period November 1986-November 1987 has evidenced long, low-frequency equatorial wave propagations over most of the equatorial Pacific basin (Delcroix et al.,1991). The succession of downwelling Kelvin, upwelling Kelvin, and upwelling Rossby waves has raised a series of questions. Is the observed upwelling Rossby wave due to a reflection process on the eastern boundary, or due to wind forcing near the equator? Why is there no evidence of a reflection of the downwelling Kelvin wave? Is this wave sequence a feature of the 1986-1987 El Nino phenomenon or is it to be found in the mean seasonal cycle? We used a linear model forced by the FSU wind stress to study these questions. The results, during the period November...

Autores: Galle, M; Weber, Jacques.
This communication presents a simple methodology for analysis of fisheries management decision making process. For each type of decision, historical recorded informations for each actor are organized in tables which allow for mesuring distances between (i) initial legal prerogatives and acquired role, (ii) the messages delivered from a period to another. The crossed representations of actors in each others meetings are included in a second table which allow for analysis of the respective power and influence of each actor in the decision making process. This methodology is tested in the case of French Mediterranean fisheries, for two types of decisions: (i) management of the three miles coastal zone; (ii) access to loans and subsidies. It is shown that...

Mortalités massives en élevage larvaire de Lates Calcarifer ( Mise en évidence d'un virus neurotrope )
Provedor de dados: 5
Autores: Renault, Tristan; Thouard, Emmanuel; Weppe, Maurice.
Since 1986 high mortality of hatchery-reared sea bass, Lates Calcarifer, larvae appeared in Ifremer's Pacifie Oceanological Center (Tahiti). Light and electron microscopy show vacuolation and cells with cytoplasmic inclusion bodies in the brain, the cord and the eye relina of affected larvae. Numerous non-enveloped particles identified as viral units, icosahedral in morphology and measuring about 25 nm in diameter were found in the cytoplasm of the degenerating cells. In affected larvae, these particles were isolated by density grandient centrifugations. In vitro tests on cell lines and in vivo test on fish are performed with samples of diseased larvae. And immunisation of mice are made with purified immunoglobulins of Lates calcarifer.

Epidémiologie des bivalves
Provedor de dados: 5
Autores: Grizel, Henri.
The notions of pathology and epidemiology in marine aquaculture are relatively new, especially as far as molluscs are concerned, as they've only been used for about thirty years. Although numerous studies have been conducted, and the concepts in these specific fields have evolved, only very few actions are proposed to stop the spreading of a disease. Only a few main mollusc species are cultivated throughout the world and most of them suffered or suffer from epizooties. Today, their pathological history is more solid: several infectious diseases are now known, numerous pathogens or potential pathogens have been described, diverse mortalities have been studied and several types of tumours have been observed. We now live in some cases, as for the flat oyster...

Since 1987, Japanese and French geologists, geophysicists, and biologists have been studying the North Fiji Basin Ridge within the framework of a joint project named STARMER (Science and Technology Agency of Japan—IFREMER of France). This ridge was first geologically, geophysically, and geochemically surveyed during the 1985 SEAPSO 3 cruise of the R/V Jean Charcot [Auzende et al., 1988]. At that time, water sampling and morphotectonic analysis indicated that the North Fiji Basin Ridge was technically and hydrothermally active. Within the STARMER project, four surface ship cruises have been conducted {Kaiyo 87‐88‐89 and Yokosuka 90). One significant result of these surveys is the complete mapping of the entire ridge between 14°S and 22°S (Figure 1), an area...

Investment and factor remuneration in small-scale fisheries
Provedor de dados: 5
Autores: Lantz, Frederic; Junqueira-lopez, R.
Investment behaviour is a complex process which plays a major role in fisheries dynamics because it determines the size of the fishing fleet. The purpose of this paper is to examine the consequences of the main characteristics of fishing activity on investment. The theoretical dynamic model of a fishery shows us the "bangbang" pallern of investment. Furthermore, fishing activity has a high intrinsic variability. Thus, the system in which income is shared between the crew and the ship owner is also considered as a way of sharing risks and so reducing the variability ofinvestment return. Finally, the type of investment financing (subsidies, loans) can strongly stimulate fisheries dynamics but can also have some undesirable effects. [NOT CONTROLLED OCR]

Production and downward flux of zooplankton fecal pellets in the anticyclonic gyre off shikoku, japan
Provedor de dados: 5
Autores: Ayukai, T; Hattori, H.
Sediment trap experiments were conducted to assess the production, disintegration and downward flux of zooplankton fecal pellets in the upper 500 m water column of the anticyclonic gyre off Shikoku, Japan. The particulate organic carbon (POC) flux decreased from 53.7 mgC M-2 d-1 at 50 m to 23.7 MgC M-2 d-1 at 500 m. The POC flux at the bottom of the euphotic layer (100 m) was 37.9 mgC m-2 d-1, which was equivalent to about 5 % of the daily primary production in the gyre. The estimated pellet carbon flux accounted for 0.4-1.7 % of the total POC flux. The pellet flux rapidly decreased in the upper 150 m layer, in parallel with the decrease in zooplankton abundance. A mid-depth peak of pellet flux, not associated with a noticeable population of zooplankton,...

Comportement du cadmium et du mercure lors de la diagenèse précoce et flux à l'interface eau-sédiments en zone littorale

Autores: Gonzalez, Jean-louis.
The early diagenesis of Cd and Hg has been studied in different coastal areas (vasière Ouest-Gironde, Pertuis d'Antioche, baie de Marennes-Oléron). For these two metals, the fluxes at the sediment-water interface have been calculated. Considering only molecular diffusion, the diffusionnal fluxes of Cd and Hg to the colurnn water are negligible with regard to both the particular fluxes to the sediments and the inputs of the "Gironde" and "Charente" ·,estuaries. The take into account of the different processes which affect the ex changes at the interface (erosion, bioturbation) permits more realistic an estimation of the role of sediments in the geochemical cycle of Cd and Hg. The results show that up to 50% of particular Cd and Hg which are integrated into...

Autores: Maes, P; Paillard, C.
The symptom which characterizes the brown ring disease (BRD) in Manilla clam Ruditapes philippinarum has been observed in other Bivalvia species (Veneridae and Pectinidae). Vibrio P1, responsible of the BRD in R. philippinarum , has been detected in other Veneridae which were carrying the symptom. In mussel and oysters which are cultivated in Europe, the symptom has never been reported and Vibrio P1 has not been detected. Experimental contaminations of bivalves of commercial interest with the pathogen showed a clear Vibrio P1 sensitivity of European clam R. decussatus ; this latter seems however to be less sensitive than the Manilla clam.

In order to calculate the behaviour of thin structures of laminated composite materials, a bidimensional plate model is generated by an asymptotic development technique. From a structural analysis by plane finite elements at the middle surface, this model yields the equations leading to the computation, at each point of the laminated material, of the displacement and the stress tensor. After describing the theoretical model, numerical results are compared with the analytical solution of a test problem.

Autores: Bacher, Cedric; Baud, Jean-pierre.
Seasonal growth of juvenile oysters (Crassostrea gigas) kept in an intensive upwelling system was studied from 1984 to 1986 in 60 to 90-day growth experiments. Saline ground water was used to produce Skeletonema costatum which was injected as food into the water supplying the upwelling system. Oyster density, water flow, phytoplankton concentration, temperature and frequency of food addition were controlled. Oyster growth was analysed with multidimensional contingency tables and correspondence analysis. The factors, in order of decreasing influence on growth, were temperature, food concentration and oyster density. A rearing strategy was deduced from the growth analysis for summer and winter. In summer, the density of  120,000 oysters/m2, the flow rate of...

The currents and circulation of the adriatic sea
Provedor de dados: 5
Autores: Orlic, M; Gacic, M; Laviolette, Pe.
This paper reviews the present state of knowledge of the Adriatic general circulation and its higher-frequency current variability. All studies show that the surface circulation consists of a large-scale cyclonic meander with several smaller cells embedded in it, and that the circulation system is modulated seasonally. Water mass analyses and direct current measurements indicate that the cyclonic meander also occurs in the intermediate layer, dominated by the current that inflows along the eastern coast. In the bottom layer, an outflowing current pressed against the western coast prevails. The circulation patterns are constantly perturbed by the higher-frequency current variations. Tidal currents modify the mean, residual flow rather weakly. On the other...

The evolution of composite materials in submarine structures.
Provedor de dados: 5
Autores: Lemiere, Y.
Since the sixties, the amount of composite structures on submarines has increased continuously. The main reasons are their low apparent weight in water, good behaviour in a marine environment, excellent mechanical properties and acoustic transparency. The new applications required the use of prepreg. Relevant processes had to be adapted to the large dimensions and thickness of the structures. Future applications will be concerned with both structures and internal equipment. A lively debate is now in progress over whether the successor to high yield strength steels for hull structures will be titanium or composite materials.

Mollusc culture began formerly in Mexico in 1800, with the pearl oyster Pinctada mazatlanica. Oyster culture began in a commercial basis in the sixties, as an activity developed by the Mexican government in the Gulf of Mexico, yet the exploitation of the species was until 1989 reserved to fishermen grouped in cooperatives. Production data shows a noticeable variability up to 1986; from then, yearly production averaged 50,000 tonnes of Crassostrea virginica from the Gulf of Mexico. The whole yield is consumed in the country. In order to improve the quality of this product, and to introduce it into the international market, many efforts have been made to certify appropriate areas in the Pacific coast, according with FDA requirements, and projects for...

Vertical mercury profile in relation to arsenic, cadmium and copper at the eastern north-atlantic ices reference station
Provedor de dados: 5
Autores: Cossa, Daniel; Michel, Pierre; Noel, Joelle; Auger, Dominique.
Mercury (total mercury), arsenic, cadmium, copper and nutrient concentration profiles (fourteen depths) were obtained at the ICES (International Council for the Exploration of the Sea) reference station (46-degrees-N; 6-degrees-W) in 4 680 m of water in the northeastern Atlantic Ocean. Concentrations of mercury generally ranged from 0.4 to 10 pM. The main feature of the vertical mercury profile was a broad peak between 150 and 1 500 m. Examination of the mercury profile in relation to water mass structure and comparison with nutrient and other elemental distributions suggested that its shape results from a remobilization of mercury during mineralization of sinking organic detritus combined with its intense scavenging in deeper waters.

The year 1990 is the second of a regional monitoring program on production assessment of Crassostrea in Britlany. 9 sites have been tested with 3 stations per site and 3 oysters bags in each station, at 3 different densities : 170, 210 and 250 oysters per bag. 18 month old oysters stocked in bags in march were analyzed 43 weeks later, by variables concerning growth, survival, quality... The growth was lower at higher densities, more or less according to sites. As previously, differences between sites and stations are observed, with some confirmations (higher mortalities in Aber Benoît site) and also evolutions (growth and Polydora infestations improvement in Pen Bé site).

Particulate matter from the bottom nepheloid layer, off the Rhone river mouth was sampled with a newly-designed frame code-named SYMPHY. Several spreading phases of the Rhodanian suspensions on the continental shelf were evidenced by currentmeter records, particulate matter analyses, CTD and nephelometric measurements. These data permitted the study of the mechanisms which control the aging of the suspensions during their transfer to a sea with very small amplitude tides. The bottom nepheloid layer can be defined as a vertical concentration gradient resulting from an equilibrium between the horizontal (Rhodanian inputs) and the vertical (surface nepheloid layer) components of the particulate flux. The variability of this equilibrium, controlled by...

Un suivi expérimental d'élevage de moules en poches a permis de classer entre elles les différentes stations de l'Aber Wrach, et d'optimiser la charge des poches (4 kg par poche préférable à des charges plus élevées).  Cependant, la croissance a cessé à partir du mois de septembre et l'indice de condition s'est dégradé, alors que sur un site voisin ou l'année précédente sur le même site, les résultats d'élevage étaient satisfaisants. Les paramètres d'environnement disponibles laissent penser à un déficit trophique, sans que cette interprétation soit totalement satisfaisante (pousse des huîtres sur le même site).

A model for the generation of nonlinear internal tides in the strait of gibraltar
Provedor de dados: 5
Autores: Longo, A; Manzo, M; Pierini, S.
A nonlinear, two-layer, rigid-lid model has been solved numerically by means of a generalized Lax-Wendroff finite difference scheme in order to study the generation of internal tides in the Strait of Gibraltar. Preliminary numerical experiments on asymptotically steady-state solutions in the presence of a constant mean flow are used to validate the model: previous laboratory experiments and analytical solutions are indeed accurately reproduced. Periodic solutions representing the internal tides at Gibraltar are then obtained by allowing a semidiurnal barotropic tidal current to interact with an idealized topographic variation modelling the Camarinal sill. Numerical experiments with and without a basic constant mean flow are carried out and a reasonable...

Provedor de dados: 5
Autores: Cailleres, J.
The germicide properties of ultra-violet radiation in a wave length ranging from 100 to 400 mm were already discovered back in the late 19th century. These properties specific to UV-C radiation (200-280 mm) result from its action on the nucleic acids of the micro-organisms. Each micro-organism, depending on its composition, therefore presents a specific sensitivity to this radiation.

Importance de la spéciation des métaux et composés organométalliques pour une bonne évaluation des risques environnementaux en milieu marin. Cas du mercure, de I'arsenic et de l'étain
Provedor de dados: 5
Autores: Michel, Pierre.
Methylmercury toxicity for sea-food consumers is well known long time ago. Tributyltin used as antifouling in paints is toxic at a level as low as 1 ng/l for oysters gastropod. At the opposite, organoarsenic compounds and especially arsenobetaine from fishes are much less toxic than inorganic species. Moreover, besides toxicological considerations, the biogeochemical fates of these elements need a good knowledge of the chemical forms of environmental inputs and of their behaviour in the various compartments (waters, sediments, biota). These phenomenons will be better understood by discussing typical applications.

The aim of the YOKOSUKA 91 cruise (October 1991) of the Japanese submersible Shinkai 6500 was to come back on two hydrothermal sites of the axis of the North Fiji Basin ridge which had already been explored by the submersible Nautile in 1989. This cruise gave us the opportunity to show that the hydrothermal manifestations vary a lot in terms of geology, geochemistry or biology during a very short time. A new site which is located in a deep graben of the N 160 ridge axis showed only activity along a fault system marked by sulphide deposits.

Les virus sont rejetés en quantité considérable dans le milieu aquatique et ce par le biais des eaux usées urbaines fortement chargées en microorganismes. Le traitement de ces eaux n'étant pas d'une efficacité parfaite en ce qui concerne les virus, une quantité non négligeable de ces derniers persiste dans les eaux épurées qui sont rejetées dans les eaux superficielles et en particulier dans les mers. En zones conchylicoles côtières, la présence de virus dans l'eau de mer constitue un risque potentiel de contamination des coquillages.

A recent product, now five years old, Nidaplast is an extruded polypropylene honeycomb, coated on both faces by a non-woven polyester. Its widespread uses extend from public buildings including water treatment plants through to the composites industry. To all these cases the honeycomb structure brings its well-known physical and mechanical properties of lightness and strength. In addition, the flexible coating on the faces allows easy fabrication which is not the case for normal honeycombs. The polypropylene offers chemical inertness and non-toxicity.

Flambement global et local des materiaux composites: Application aux mats de voiliers
Provedor de dados: 5
Autores: Devaux, H.
The mast-rigging combination of a yacht is the structural element which transmits the aerodynamic forces on the sails to the yacht's structure. This load transmission element is in general made up of a mast, a long, thin tube, and the rigging which is a collection of cables linking the mast to the deck. These elements are long, often longer than the hull, with a high centre of gravity and it is essential to obtain as low a mass as possible, both for safety and performance. This search for weight gain imposes the use of lighter and lighter materials: wood, then aluminium alloys and most recently, since the early 1980's, composite materials. The use of the latter is the subject of this paper.

Effect of ionizing radiation onVibrio bacteria in Crassostrea virginica (American oyster)
Provedor de dados: 5
Autores: Eberiel, D; Dooley, K; Langton, L; Malleth, J.
The presence of Vibrio bacteria in raw shellfish poses a significant health hazard to the consuming public. These human pathogens are natural, seasonal components of the microbial flora of shellfish which can result in primary septicemic or diarrheal fatal infections. Existing shellfish depuration neither targets nor eliminates the Vibrio bacteria. For this reason, additional purification processes are necessary. In this study, the effect of low dose gamma radiation on the inactivation ofVibrio cholerae (01 and non 01) and vulnificus is investigated. Log decrement (D10) values ranging only to a high of 0.09 KGy in the Vibrio strains support the hypothesis that food irradiation technology can provide an additional effective and efficient shellfish...

Shellfish culture is widely spread throughout the world and is the focus of an important activity either as a fishing of shellfish deposits or as a culture. The greatest production areas are Northern America with the United States and Canada. Asia with Japan and Korea, Europe with France, the Netherlands and Spain. At some point, each of these countries has had to face more or less important epizooties of variable durations. Each time, some studies have been carried out to try and find the origin of the disease, understand its evolution and look for solutions to the crisis it lead to. If, in most cases, these mortalities could be linked to the presence of some infectious agents, some phenomena still remained unexplained, the mortalities potentially being...

Distribution and seasonal variability of nutrients and dissolved-oxygen in the northeastern ionian sea
Provedor de dados: 5
Autores: Souvermezoglou, E; Hatzigeorgiou, E; Pampidis, I; Siapsali, K.
In this paper we present for the first time detailed nutrient and oxygen figures for the Ionian Sea. The data were collected during cruises in March-April 1987 and August-September 1987, in the framework of the multi-nation research programme for the exploration of the Eastern Mediterranean, POEM. The oxygen and nutrient pattern is affected by the presence of mesoscale cyclonic and anticyclonic gyres in the area, the most interesting feature of which is the large anticyclonic flow region southwest of Peloponnesus (Pelops gyre). The chemical characteristics of the main water masses were also determined. In the deep layer of the stations near the Otranto Strait we have found, in winter, newly formed Adriatic Bottom Water (O2 : 5.3 ml/l). This water mass has...

The temporary bad bacteriological results in some shellfish harvesting areas in Brittany (France) lead us to recommand the use of insubmersible aerate tanks in shellfish plant. The shellfish depuration kinetics are as good as those noted in purification plants using chemically or physically purificated water. The generalisation of this technic to a regional scale corroborates its efficiency and allows us to fix good practice rules. The observance of these rules must lead shellfish-grower to sell, permanently, bacteriologically proper products.

Applications de la thermographie infrarouge au controle non destructif des materiaux composites utilises en construction navale
Provedor de dados: 5
Autores: Lesbre, F; Potet, P; Artiga, F.
Composite materials used in naval construction use mainly glass fibres and fabrics and epoxy resins for monolithic structures and syntactic foams or balsa wood for the core of sandwich structures. Traditional non destructive testing (NDT) methods such as ultrasonics or radiography do not always ensure a complete check of the structure, principally due to the strong heterogeneity of these materials. In order to improve this situation the DCN has developed a test method based on the use of active infrared thermography. The technique consists of illuminating the structure with a powerful lamp and observing the cooling of the surface with an infrared camera. Defects present act as obstacles to heat transmission in the material and cause thermal anomalies on...

Retention efficiency in oyster Crassostrea gigas exposed to variable food quantity and quality
Provedor de dados: 5
Autores: Barille, Laurent; Prou, Jean; Heral, Maurice; Bougrier, Serge.
Relative retention efficiency (Er%) of Crassostrea gigas was estimated in the laboratory with 7 diets consisting of algae and silt. Total particulates varied from 1.34 mg/l in natural sea water to 27.65 mg/l in natural sea water enriched with silt. It was also calculated from field experiment to get high concentration of seston up to 66 mg/l. It appeared that Crassostrea gigas did not adjust its retention according to the food quality and the gill porosity was controlled by the concentration of particulate matter. In low seston load (1.34 mg/l) the oyster showed no change in retention for particles larger than 3-4 µm (Equivalent Spherical Diameter, ESD) but at the highest concentration (66 mg/l) it could only retain with a maximum efficiency particles...

The tested products were Lime, and an antiseptic "Agroseptil" which positive effects are admitted in pisciculture. The results (growth, survival and the presence of brown-ring), do not point out any difference between the various treatments. However, it looks as if the brownring has appeared latter than on other clam-fields located in the same area.This effect does not seem to be due to the various treatments of the soils, but to the antibiotic  bath of the clams bef ore seeding.

Organic carbon flows through the Pierre Noire fine sand community (Bay of Morlaix, France) are described with a trophodynamic point model, Data collected during several annual cycles are used to calibrate the seasonal variations of each benthic compartment. Mean annual values of state variables are correctly simulated. In a first approach, the seasonal variations were simulated using 2 forcing functions: input of energy and temperature influence. In a second run, spawning and recruitment effects were introduced as regulating factors for the macrobenthic compartments. The resulting annual carbon budget synthesizes the information we have on this common type of ecosystem. Phytoplankton production represents the major food supply to the benthic system and the...

Note on the use of an altimeter mean sea-surface for mesoscale variability studies
Provedor de dados: 5
Autores: Blanc, Frederique; Le Traon, Pierre-yves.
This report discusses whether, by the year 1995, altimeter mean surfaces such as those generated by Geosat, ERS-1 [35 days] and Topex-Poseidon will be accurate enough for extracting the variable ocean signal. The mean oceanic signal is estimated from altimetry using an inverse method. Because of the large number of altimeter measurements, the original one-step method is transformed to a two-step method, the iterative inverse method. The space-time distribution of the altimeter data is only needed to calculate the formal error on the altimeter mean surface. Using a year of satellite altimeter measurements, the mean rms errors are 10 cm for Geosat, 8 cm for ERS- 1 and 13 cm for Topex-Poseidon. The along-track minima are respectively 8, 7 and 5 cm rms.

A new cryptic species of lizard (Sauria: Teiidae: Gymnophthalmus) from Venezuela
Provedor de dados: 16
Autores: Hoogmoed, M.S.; Cole, C.J.; Ayarzaguena, J.
Gymnophthalmus cryptus spec. nov. is described and illustrated on the basis of males and females collected in the Territorio Federal Amazonas, southern Venezuela. Some details on ecology and distribution are also presented. The females of G. cryptus are very similar to the unisexual Gymnophthalmus underwoodi, which also occurs in the Guianan Region. In fact, G. cryptus is one of the best candidates for future genetic research to determine whether it is the missing ancestor of G. underwoodi, a parthenogenetic species of hybrid origin (G. speciosus x G. spec.?). Two other series of previously unreported species of Gymnophthalmus from Venezuela are also discussed.

During the Amsterdam Expedition to Ascension Island in 1989 eighteen species of polychaetes were collected, fifteen of which were already known to science. One could not be identified to species level and two were new to science: Aricidea (Aedicira) ascensionensis n. sp. and Notodasus arenicola n. sp. Four of the known species are widely distributed, three are circumtropicalsubtropical and one has a tropical-subtropical distribution in the Pacific and in the Atlantic Ocean. Another species is recorded from different regions in the Atlantic Ocean. The rest of the species were – until now – only known from their type localities, viz. West Indies, Angola, Persian Gulf, Galapagos Islands, and South Shetland Islands.

This year it is 175 years ago that the Botanical Garden of Bogor (’s Lands Plantentuin, Buitenzorg) was founded. From a humble origin it became one of the most important gardens in South East Asia, if not of the whole tropical world. Its history has been extensively described by Rijnberg (1922) and briefly by Ms. Soegiarto (1992), unfortunately only in Dutch and Indonesian, respectively. Set up as an experimental garden for the cultivation of species of economic importance, it has been instrumental in the introduction of the oilpalm, rubber, and kina in Indonesia and surrounding countries. As the various staff members made extensive exploration tours over the then Dutch East Indies many species were brought back of unknown value, and at its height there...

The taxonomy and biogeography of the genus Thaumastopsaltira Kirkaldy, 1900 (Homoptera, Tibicinidae)
Provedor de dados: 16
Autores: Boer, A.J. de.
The taxonomic concept of the genus Thaumastopsaltria Kirkaldy is redefined on the basis of the shape of postclypeus and the length of the ovipositor. Tegmen venation is shown to be unreliable for this purpose. T. nana (Jacobi) does not fit this new concept and is, pending its transfer to another genus, not included in this revision. The genus now consists of a monophyletic group of seven species, for which a key to the males is presented. Two species (T. adipata (Stål) and T. globosa (Distant)), are redescribed, while five (T. sicula, T. lanceola, T. pneumatica, T. sarissa and T. spelunca) are described as new. T. glauca Ashton is brought into the synonymy of T. globosa. Thaumastopsaltria belongs to a group of New Guinean and Australian genera, defined...

In the first sentence of the Preface the elusive concept of ethnobotany is defined in a rather restricted way: “the study of the use of plants by indigenous people”, ‘indigenous’ obviously meaning non-Western and not technologically advanced. Most of the chapters in this book (or rather: the papers brought together in this Symposium volume) agree with the definition given: Banack on plants used in making boats and during voyages; Kirch on agricultural systems; Abbot on uses of seaweeds; Cox on medicinal plants; Lebot on the use of Piper methysticum; Ragone on Artocarpus altilis. These chapters contain interesting stuff, as well from the anthropological as from the botanical point of view. Most of them are also well-written. I found especially the chapter...

Records of Dusky Dolphins, Lagenorhynchus obscurus (Gray, 1828) in the eastern South Pacific
Provedor de dados: 16
Autores: Waerebeek, Koen van.
Fourty-seven authenticated locality records of the dusky dolphin along the west coast of South America are presented, based on original data, museum specimens and the literature. Confirmed distribution limits are Chimbote (09°05’S) in north—central Peru and Isla Treble (55°07’S 71°02’W), Magallanes, in southern Chile. Accounts are absent from a roughly 1,000 km coastal strip between 36°30’S and 46°S, suggesting the existence of a distribution gap. Specimens encountered south of this area are thought to form part of the Southwest Atlantic population. No abundance estimates are available but fishery mortality data indicate that L.obscurus is the most common cetacean off central Peru and, based on limited sightings, possibly also off northern Chile.

An annotated index to names of Odonata used in publications by M. A. Lieftinck
Provedor de dados: 16
Autores: Tol, J. van.
An index to all names of Odonata mentioned in publications of Maurits Anne Lieftinck (19041985) is provided. Lieftinck mainly published on the Odonata faunas of the Indo-Australian and Palaearctic regions. He revised many genera, described over 600 species and also examined hundreds of primary types of previously described species. He included with his descriptions and revisions accurate line illustrations and carefully composed lists of synonymies and references. The index to his works is therefore a key to nearly the full literature of Indo-Australian Odonata, as well as to valuable museum collections of, especially Indo-Australian, Odonata.

Autores: Hofman, Caroline C.; Kielman, Margriet.
From June till December 1987 an inventory of the excavating sponges of the Santa Marta area, Colombian Caribbean, was made by scuba diving to depths not exceeding 18 m. Sixteen species were recorded and compared morphologically, using spicule sizes, papillae shapes, and excavation characteristics. Four littleknown species are fully described and illustrated by submarine color photographs in situ. One appears to be a new species: Axinyssa flavolivescens, belonging to a genus not known to excavate so far. The other three species could not be identified with certainty: Aka äff. xamaycaensis, Aka aff. brevitubulata, and Cliona aff. flavifodina. A key to the excavating sponges of the area studied is provided.

A revision of Atlantic Asteropus Sollas, 1888 (Demospongiae), including a description of three new species, and with a review of the family Coppatiidae Topsent, 1898
Provedor de dados: 16
Autores: Hajdu, Eduardo; Soest, Rob W.M. van.
Various records of A. simplex Carter, 1879 from the Atlantic are assigned to three new species of the sponge genus Asteropus Sollas, 1888, viz.: A. brasiliensis sp. n., A. vasiformis sp. n., and A. niger sp. n., whereas A. simplex s.s. is restricted to the Indo- Pacific. A worldwide study of Asteropus specimens resulted in the conclusion that two species groups exist, namely “simplex”- like species (with true sanidasters), and “sarasinorum”-like species (with spiny microrhabds), as previously observed by Bergquist (1965, 1968). A newly discovered microsclere complement of trichodragmata in the first group strengthens the need for generic distinction of both lineages, and accordingly the name Melophlus Thiele, 1899 is reinstated for the “sarasinorum”...

Autores: Baas, P.
This volume on leaf venation patterns is too modest in its title. Not only the Combretaceae are treated, but not less than eleven other families: Lecythidaceae, Barringtoniaceae, Foetidiaceae, Napoleonaceae, Rhizophoraceae, Anisophylleaceae, Lythraceae, Sonneratiaceae, Oliniaceae, Punicaceae, and Onagraceae. Thus, together with the earlier volumes on Myrtaceae and Melastomataceae plus Memecylaceae, the present book effectively completes the venadon survey of the order Myrtales in its widest possible circumscription. Lecythidaceae and Rhizophoraceae and their satellites do not fit well into the order. Altogether the leaves of 479 species are described and pictured, resulting in a wealth of welcome descriptive information. Criticisms voiced about the earlier...

Provedor de dados: 16
Autores: Szabó, J.; Conti, M.A.; Monari, S.
Members of Ataphridae became a progressive group in one of the two types of Tethyan faunas. Some of the new forms, which evolved from ataphrid ancestors, can be classified within the family, whilst others show a transitional morphology towards the turbinid subfamily Colloniinae. Other finds suggest a close relationship between Ataphridae and Crossostomatidae.

[Proceedings of the symposium 'Molluscan Palaeontology' : 11th International Malacological Congress, Siena (Italy) 30th August - 5th September 1992 / A.W. Janssen and R. Janssen (editors)]: The bivalve shell as a preservation trap, as illustrated by the Late Jurassic gryphaeid, Deltoideum delta (Smith).
Provedor de dados: 16
Autores: Todd, J.A.
Three processes by which a bivalve shell can preserve soft-bodied organisms during its secretion are described. These are: a) bioimmuration by the attachment area of a cementing bivalve, b) bioimmuration by a growth lamella and, c) deformation of the periostracal sheet. Examples of all three are provided by the Late Jurassic gryphaeid Deltoideum delta (Smith, 1817); Recent examples are also given. Extrapallial cement - here termed the Harper layer - is shown to have been produced throughout growth in this species, which allowed accurate lamellar bioimmuration as well as facultative recementation of the left valve. The importance of bivalve shell secretion for the preservation of unmineralized, hard-substrate-dwelling epibionts in the fossil record is...

On a new species of blackwater prawn, Macrobrachium oxyphilus (Crustacea: Decapoda: Caridea: Palaemonidae), from peat swamps in Peninsular Malaysia
Provedor de dados: 16
Autores: Ng, P.K.L.
A new species of freshwater palaemonid prawn, Macrobrachium oxyphilus spec, nov., is described from highly acidic blackwaters in a peat swamp forest in Selangor, Peninsular Malaysia. The species differs from its nearest congener, M. trompii (de Man, 1898), in having proportionately smaller eyes, shorter scaphocerites, a lesser number of ventral rostral teeth, a more inflated carapace, and less pubescent and more spiniferous chelipeds.

Species of the genus Sertularella from the coasts of Galicia (Atlantic coast of Spain) have been studied and 5 species, S. gayi (Lamouroux, 1821), S. polyzonias (Linnaeus, 1758), S. ellisii (Deshayes &amp; MilneEdwards, 1836), S. fusiformis (Hincks, 1861), and S. mediterranea Hartlaub, 1901, are recognized, described, and their synonymy discussed. Notes are added on two species of which the names occur repeatedly in European hydroid literature but that in our opinion belong in the southern Atlantic fauna: S. gaudichaudi (Lamouroux, 1824) and S. picta (Meyen, 1834).

Autores: Bouman, F.; Devente, N.
Stemona and Pentastemona differ clearly in the size and structure of their ovules and seeds. Especially the development, shape, and cell wall thickenings of the endotestal cells, and by consequence the origin of the seed ridges, show marked differences. The embryological and seed anatomical characters support the proposal to give Pentastemona a family status.

This special issue of Persoonia is dedicated to Dr. R. A. Maas Geesteranus who celebrated his 80th birthday on January the 20th 1991 in good health and spirits. Dr. Maas Geesteranus retired in 1976. On this occasion a biographical note and a list of his publications were published (Persoonia 8: 335-343. 1976). What only could be hoped then has fortunately come true: he intensively continued his excellent research in the taxonomy of macromycetes. In the last fifteen years an uninterrupted stream of more than 50 papers were published.

Evolutionary side-steps
Provedor de dados: 16
Autores: Sluys, Ronald.
Many of the lower metazoans reach adulthood via complex developmental stages. Each of these stages is described with a specialized terminology, which is different for every major group of organisms. Biologists with a proper training in biodiversity may have learned about these complex issues during their undergraduate days, but many of us do no longer encounter the intricacies of lower metazoan development in later stages of our careers. We may be familiar with the ontogenetic stages in the group on which we specialize, but only a few will have practical knowledge and an overview of the larval stages in such groups as crustaceans, echinoderms, polychaetes, sipunculans, molluscs, flatworms, bryozans, and nemertines.

Psilocin, psilocybin, serotonin and urea in Panaeolus cyanescens from various origin
Provedor de dados: 16
Autores: Stijve, T.
The occurrence of tryptamine derivatives and urea in Panaeolus cyanescens, also known as Copelandia cyanescens, from Australia, Hawaii and Thailand was investigated. All 70 collections contained psilocin, serotonin and urea. Those from Hawaii were also relatively rich in psilocybin, whereas the species from Australia and Thailand were virtually exempt of this compound. Many collections also contained detectable amounts of precursors as tryptophan, tryptamine and baeocystin, but 5-hydroxytryptophan — widely encountered in many other Panaeoloideae — was found to be absent in all samples. The role of these 4- and 5-hydroxylated tryptamine derivatives in the metabolism of the fungus and their possible chemotaxonomic significance is briefly discussed....

Autores: Kits van Waveren, E.
Attention is drawn to the fact that, although the shape of the pleurocystidia (utriform versus lageniform and/or fusiform) plays a part on sectional and specific level in Psathyrella, sometimes this pattern is broken by variants with uniform pleurocystidia within species normally with lageniform and/or fusiform pleurocystidia. Five examples are discussed, viz. P. umbrina, P. bipellis, P. obtusata, P. prona, and P. ocellata.

Boletus impolitus and B. depilatus are known from the Benelux; up to now the latter is found only in Belgium. Both species occur on calcareous soils; B. depilatus, however, seems to prefer soils with a higher calcium content than B. impolitus. The most reliable diagnostic characters are found in the pileipellis, at both the macroscopical and the microscopical level. It is possible that B. depilatus is more thermophilous.

Provedor de dados: 16
Autores: Harper, E.M.; Skelton, P.W.
The well documented dramatic increase in predation pressure which started during the early Mesozoic, termed the Mesozoic Marine Revolution (MMR), had an important impact on the evolution of prey organisms (Vermeij, 1983). Epifaunal bivalves in particular are at considerable risk to predation. In this paper we consider the types of predation to which epifaunal bivalves are prone and outline the evolutionary history of the different modes of predation. We explore methods by which bivalves are known to evade these activities and chart the appearance of these defences in the fossil record. These sections involve both review of the massive existing literature on molluscivory and the presentation of new experimental data, in particular on the value of...

Provedor de dados: 16
Autores: Lange, Morten.
Development of the macromycete flora of windfall beech logs in different stages of decay were studied over 10 years. The occurrence of 48 species found on more than six logs are discussed in relation to five 5-year periods of progressing decomposition. The first period has several distinctive species confined to hard bark and fresh wood. Also the second period with desquamating bark has distinctive taxa. Polyporaceous species have a slight dominance in this period, while saprophytic agarics are more frequent in the later periods. Many species, including Armillaria mellea, Fomes fomentarius and other necrotrofic parasites are met in all 5-year periods. The final stage of decay is characterized by slow invasion of species of the forest floor.

Drastic changes in the amphipod fauna (Crustacea) of Dutch inland waters during the last 25 years
Provedor de dados: 16
Autores: Pinkster, Sjouk; Scheepmaker, Maarten; Platvoet, Dirk; Broodbakker, Nico.
After the introduction of Gammarus tigrinus in The Netherlands some 25 years ago and of other recently invading amphipods (Crangonyx pseudogracilis and Corophium curvispinum) the native species decreased, the invaders increased. The success of these invaders and its impact on the local amphipod fauna is discussed. Electrophoretic tests give evidence that a second invasion of Gammarus tigrinus, this time from Germany, is taking place. Some predictions about future developments are made.

Autores: Bakker, M.E.; Gerritsen, A.F.
The morphology and distribution patterns of oil and/or mucilage cells, i.e. idioblasts, in the leaf of 37 Annona species are described. Idioblasts are always present in the spongy parenchyma in all species and in most cases also in the palisade parenchyma. Usually both oil cells and mucilage cells occur; in some species either oil or mucilage idioblasts are present. Their number ranges from few to abundant Both idioblast types possess a suberized wall layer. Mucilage cells are significantly larger than oil cells. The distribution patterns of oil and/or mucilage cells often do not coincide with the current classification into sections. Leaf features such as lamina thickness, the presence of sclereids in the mesophyll, crystals in the adaxial epidermis,...

Autores: Krzyminska, J.
Investigations were carried out at the State Geological Institute (Marine Geology Branch, Sopot, Poland) on the base of 2500 samples collected by means of a van Veen grab during research cruises in 1973-1990. For a macroscopic description of four species of Mollusca present in the bottom sediment samples, i.e. Cerastodermas glaucum (Poiret), Macoma balthica (Linnaeus), Mya arenaria (Linnaeus), and Mytilus edulis (Linnaeus), both living and dead specimens have been taken into account. A biofacial distribution map for these four species is presented. It is concluded that the type of sediment and the sea depth are the most important factors influencing the distribution of the species.

The viridis group is proposed for a supposedly monophyletic group of seven New Guinean species of the cicada genus Baeturia Stål, 1866. Three species (B. brongersmai Blöte, B. rufula Blöte, and B. viridis Blöte) are redescribed and four species (B. furcillata, B. karkarensis, B. lorentzi, and B. turgida) are described as new to science. A key to the males is provided. The phylogenetic position of the viridis group within the genus Baeturia is discussed. The distribution of shared characters suggests a subdivision of the group into two subgroups. One subgroup is restricted to southern and western Irian Jaya, while the other is distributed along the coastal mountain ranges of northern New Guinea, including Karkar Island.

While Entodon concinnus was considered almost extinct in the Netherlands, no less than six ‘new’ localities were discovered in 1990/91, all of them in elevated parts of outer-meadows along branches of the Rhine system (fig. 2). This moss appeared to thrive on somewhat open spots in the turf of dry pastures on lime-rich sand containing traces of clay, especially on mole-hills and on south-exposed slopes. All sites are grazed part of the year and most of them are situated in nature reserves. The vegetation in which Entodon occurs, belongs to the association Medicagini-Avenetum pubescentis (table 1).

We outline here the outlook for the species and aspects of their biology that need investigation. A more detailed account of the status and biology of M. l. laperouse in the Marianas is in preparation. Status and distribution The Micronesian megapode in the Marianas is now restricted to the remote volcanic islands north of Saipan, with the exception of a small remnant population on Aguijan and a reintroduced population on Saipan. In historic times, this species was found on the larger coral islands of Guam, Rota, Tinian, and Saipan, but was common only on...

Autores: Årpád, Dàvid.
Trace fossils, found on shells of gastropods, bivalves and scaphopods from Molluscan Clay exposures (Oligocene, Egerian) at Eger (Wind brickyard) and Novaj (Nyárjas Hill) (NE Hungary), were studied. The relative abundance of different types of borings, traces of bioerosion and palaeopathological phenomena indicate micro-environmental differences between the two localities.

Wawelia effusa Lundqvist, spec. nov. (Xylariaceae)
Provedor de dados: 16
Autores: Lundqvist, Nils.
Wawelia effusa Lundq., spec. nov. is described, a stromatic pyrenomycete with 8-spored, deliquescing, non-amyloid asci without apical apparatus and with limoniform spores with a germ slit. It is found on dung of hare and roe-deer in Sweden and Hungary respectively, and differs from the two other species of the genus, W. regia Namysłowski and W. octospora Minter &amp; Webster, by a basal, effused stroma, equilateral spores and probable lack of an anamorph. The stromatic nature of W. effusa is discussed, as well as the taxonomic position of the genus and the ecology of its species. The author joins those who argue for Wawelia being xylariaceous.

Ostracods from the Albian/Cenomanian boundary in the Achterhoek area (eastern part of The Netherlands)
Provedor de dados: 16
Autores: Witte, L.; Lissenberg, Th.; Schuurman, H.
The only outcrop of the Cenomanian in The Netherlands is found in the eastern part of the country, near the town of Winterswijk. Here, in the bed of a brook, the Oossinkbeek, white chalks are exposed. Not far from this locality, just a few hundred metres to the NE, the only exposure of the Albian in The Netherlands is found as well, represented here mainly by greensands and greyish siltstones. Samples from both localities were examined for their microfaunal content (ostracods and foraminifera). In addition, samples from a few wells in the surrounding area were included in the study. The recovered ostracod faunas are described in this paper. They prove that, with the exception of the top layers exposed in the Oossinkbeek, the chalks of Kotten are primarily...

Provedor de dados: 16
Autores: Engeser, T.S.; Riedel, F.; Blandel, K.
The formation of the early ontogenetic shell of Scaphopoda is reviewed. In the few known cases the embryos hatch in the gastrula stage and rapidly develop into a lecithotrophic Trochophora-like larva. Our material indicates that there might be a planktotrophic larva in some species. The clasp-like shell is formed in the larval stage (e.g. Antalis tarentina Lamarck, 1818). It later fuses into a tube and mineralises during metamorphosis. Immediately after the metamorphosis the shell increases at the anterior end (early teleoconch) and posterior end (fumarium). During further growth, the fumarium, the larval shell and finally parts of the juvenile shell are gradually resorbed. We describe several specimens with preserved protoconchs from different...

The data set of the so-called main branch of Miocene Gyraulus, collected and measured by Mensink, has been re-examined by means of multivariate methods. New information was obtained by presenting the percentage of specimens which have a keel on the second or third whorl in a bivariate way. In an earlier multivariate analysis Lindenberg &amp; Mensink used only six characters, in the present paper an additional two characters have been used. However, as the number of characters is small, some of them have not been adequately measured, and because the identification of part of the specimens was questionable, the results may still be insufficient.

An evolutionary approach to megapode mating systems
Provedor de dados: 16
Autores: Jones, D.N.
An evolutionary understanding of the complex mating systems of megapodes has been impaired by a historical and simplistic classification system that assumed all species to be monogamous. This approach has been challenged by behavioural ecology theories that emphasize the primacy of the individual attempt to maximize its own fitness. From this point of view the remarkable incubation techniques and the recently described behaviours of some clearly promiscuous species can be more clearly understood. In particular, the influence of the type of incubation-heat source on the mating system is paramount.

Planorbid shells are abundant in the sediments of the fresh water lake of Steinheim am Albuch throughout its depositional history. They were studied repeatedly after Hilgendorf's (1867) initial work. He had all different morphs that appeared during the long lasting lake history related to a single founder species that developed into several lineages, one of which was designated as 'main-branch' with large conspicuous morphs. Most subsequent studies are concerned with that branch. Based on new material and aided by SEM studies of the protoconchs, the small side-branch morphs have been restudied and evolutionary lineages are reconstructed. As a result the phylogenetic lineages of planorbids from lake Steinheim can be considered to have evolved from a single...

Sur l’ordre des Pluteales Kühner
Provedor de dados: 16
Autores: Romagnesi, H.
The fleshy volva-like body from which the young fruit-body of Rhodocybe stangliana (Entolomataceae) develops is not a sclerotium. It is a derived stage of the primordial bulb. Post-primordial sections show striking analogies to similar sections of fruit-bodies of Volvariella (Pluteales). Therefore Rhodocybe stangliana is a species intermediate between two families which by appearance look widely apart. This confirms the classification proposed by Kühner, who brought these two families together in one order (Pluteales), mainly on account of a similar ultrastructure of the spore wall and a similar behaviour of the spore wall after treatment with ammonia and acetic acid, with as single intermediate Macrocystidia cucumis.

One knows what can be expected; as far as I can see nothing has been changed as compared with the 18th Supplement. Worth mentioning is that whereas the 18th Supplement came out about one and a half year after the closing date – at that time already exceptional – with the present one this has been brought back to less than one year: the official date of publication is 15 November 1991. Important news can be found in the Foreword: “The printed annual Kew Index has been discontinued, but there are plans for a CD-ROM version of the complete Index Kewensis ... This electronic version is due to appear in 1992.” Whether additions will come out annually or...

Flowers of annonaceae: Morphology, classification, and evolution
Provedor de dados: 16
Autores: Heusden, E.C.H. van.
The present paper describes the diversity in floral characters of Annonaceae and their distribution over the family, and discusses their value for classification and generic delimitation. Flower morphology predominated historical classifications of this family since Hooker &amp; Thomson (1855) introduced floral characters to divide the Asiatic genera into a number of tribes. Since then, several taxonomists presented a classification of the Annonaceae using floral characters, which classifications, however, are generally felt as unnatural. A survey of the flower morphology of all genera reveals a reticulate distribution of floral character states. Classification of the genera, as presented in this study, learns that floral characters different from those in...

On a new species of Geosesarma de Man, 1892 (Crustacea: Decapoda: Brachyura: Grapsidae) from Chanthaburi Province, eastern Thailand
Provedor de dados: 16
Autores: Ng, P.K.L.; Naiyanetr, P.
A new species of terrestrial freshwater sesarmine crab (Decapoda: Brachyura), Geosesarma krathing spec, nov., is described from near a waterfall in Chanthaburi Province, eastern Thailand. This is the first record of the genus from that part of Thailand. The species is allied to G. peraccae (Nobili, 1903) from Singapore and southern Peninsular Malaysia, but differs in the form of the carapace and male first pleopod structure.

SLUYS, R., 1992. Synopsis of the freshwater triclads of the Caribbean (Platyhelminthes, Tricladida, Paludicola). Studies Nat. Hist. Caribbean Region 71, Amsterdam, 1992: 1-23. An account is given of the five species of freshwater triclads which are known from the Caribbean region, including taxonomic descriptions, karyological, ecological, and biogeographic information, supplemented with remarks on observations of previous workers and comparisons with similar species. Records of unidentified specimens are summarized. Caribbean freshwater planarians belong to the genus Girardia; the phylogenetic relationships within this genus remain to be resolved. It is argued that present distributional patterns in Caribbean Girardia’s may be the result of vicariance...

Insectivore faunas from the Lower Miocene Anatolia. Part 1: Erinaceidae
Provedor de dados: 16
Autores: Hoek Ostende, L.W. van den.
Two new species of Galerix (Erinaceidae, Insectivora) are described from Lower Miocene localities of Anatolia. These species are G. saratji n. sp. from Kilçak 0, Kilçak 0", Kilçak 3A, Kilçak 3B, Harami 1 and Harami 3, and G. uenayae n. sp. from Keseköy. The recent literature on Galerix is reviewed and the phylogenetic relationships of the Early Miocene species of Galerix are elaborated.  The presence of the erinaceid Neurogymnurus in Kilçak 3A indicates that the Kilçak localities are probably older than the Harami localities.

The recurrence of Vogelgnathus campbelli-dominated conodont faunas in the Viséan and early Namurian of the Cantabrian Mts (Spain): a reflection of sea-level fluctuations?
Provedor de dados: 16
Autores: Boogaard, M. van den.
The conodont faunas from the Viséan and lower Namurian limestone succession in the Cantabrian Mts are mainly characterised by abundant Gnathodus spp. and minor amounts of Lochriea spp. However, Gnathodus and Lochriea are four times largely or almost completely replaced by Vogelgnathus campbelli, every time during a relatively short interval. Apart from being present in moderate quantities in basal Viséan faunas, V. campbelli is lacking in most of the Gnathodus-dominaled faunas from the Cantabrian Mts. These invasions by V. campbelli are supposed to have occurred during a rise of sea level enabling this - presumably more offshore - species to enter the region while at the same time the habitat of Gnathodus c.s. was partly or almost completely drowned. These...

What is Cynodon radiatus Roth ex R. &amp; S. (Poaceae)?
Provedor de dados: 16
Autores: Nowack, R.
Roemer and Schultes (1817) described Cynodon radiatus, basing themselves on a manuscript by A.W. Roth, copying Roth's brief diagnosis and comment. It was compared to Cynodon dactylon, differing by its larger habit, the number and direction of the spikes, and the glabrous blades and sheaths.  This was of course insufficient to be able to deduce whether this was a mere form of C. dactylon or indeed a distinct species.

Samples collected in underground waters of Spain by Ine Meijers and Jos Notenboom demonstrated the presence of some oculated asellids previously known: Proasellus coiffaiti, P. coxalis, and P. meridianus, and also four new stygophilous species, more or less depigmented, with different stages of regression of the ocular system: P. beticus n. sp., P. ortizi n. sp., P. aragonensis n. sp., and P. ebrensis n. sp. These forms represent relict populations of ancient epigean species. The anophthalmous species of the Aquitanian Basin, Pyrenees, and Iberian Peninsula are more closely related to P. beticus and P. ortizi than to the Recent epigean species P. coxalis and P. meridianus.

Leaf anatomy of the Melastomataceae, Memecylaceae, and Crypteroniaceae
Provedor de dados: 16
Autores: Mentink, Helmy; Baas, Pieter.
The leaf anatomy of the Melastomataceae, Memecylaceae and Crypteroniaceae is surveyed on the basis of 179 samples representing 151 genera. The Melastomataceae appear to be leaf anatomically very heterogeneous. An unusual diversity of hair types is present, varying from simple unicellular hairs to very complex multicellular, non-glandular or glandular trichomes. Elongate multiseriate unbranched non-glandular hairs and short-stalked glandular hairs are most common. Stomata generally are polo-, dia-, tetra-, and anomocytic; other types and intermediate kinds also occur. A hypodermis is sometimes present. The mesophyll is usually dorsiventral, rarely isobilateral. Sclereids of various types are present in some genera. Crystals are usually druses, sometimes...

Floral morphology of Stemonaceae and Pentastemonaceae
Provedor de dados: 16
Autores: Heel, W.A. van.
The early development of the stamens in Stemona and Stichoneuron is similar, in spite of significant differences in the adult stages. Moreover, as the peculiar gynoecia in both genera are chiefly similar, their mutual affinity seems substantiated. It is concluded that Stichoneuron is very close to Croomia, so that these genera can be merged. However, Pentastemona is different. In its androecium it shows a corona-like development of the basal staminal region (like Peliosanthes, Convallariaceae). Therefore, the removal of Pentastemona from the Stemonaceae is corroborated. The late differentiation of its stamens into extensions that contact the stigma, as well as the inferior position of the ovary, suggest a relationship with Trichopus (Trichopodaceae) and...

Leaf anatomy of Cinnamomum schaeffer (Lauraceae) with special reference to oil and mucilage cells
Provedor de dados: 16
Autores: Bakker, M.E.; Gerritsen, A.F.; Schaaf, P.J. van der.
The morphology and distribution patterns of oil and mucilage cells in the leaf of 150 species of Cinnamomum are described. Idioblasts are always present in the palisade and the spongy parenchyma. Usually both oil and mucilage cells occur; in some species either oil or mucilage cells are present. Both types of idioblasts possess a suberized wall layer. The idioblasts vary between species in size/ shape, stainability and number. Variations in the distribution pattern can partly be explained by the proposed homology of the oil and mucilage cells. Other leaf anatomical characters are also mentioned, such as lamina and cuticle thickness, bundle sheath extensions, sclerification of the epidermal, the palisade, and the spongy parenchyma cells, number of palisade...

Formal description of the family Pentastemonaceae with some additional notes on Pentastemonaceae and Stemonaceae
Provedor de dados: 16
Autores: Duyfjes, Brigitta E.E.
The discriminating characters of some genera of the family Stemonaceae (incl. Stemona) and the genus Pentastemona (formerly in the Stemonaceae) have been amply discussed by the present author (1991). The discussion resulted in the statement that Pentastemona represents a family of its own, Pentastemonaceae, beside Stemonaceae. The forthcoming treatment of both families in Flora Malesiana (Duyfjes, 1992) requires the formal description of Pentastemonaceae. The supporting considerations for the distinction of the new family are briefly enumerated again: Pentastemonaceae (Pentastemona) Stemonaceae Growth habit monopodial sympodial Leaves dispersed distichous, opposite or verticillate Petioles shortly sheathing at the base not sheathing at the base Scale...

Robustunguis gen. nov., a genus of decapod associated laophontids (Copepoda: Harpacticoida)
Provedor de dados: 16
Autores: Fiers, F.
The genus Robustunguis gen. nov. is erected for two species of laophontid harpacticoids: R. ungulatus spec. nov. and R. minor spec. nov. Both species were recovered from washings of decapod crustaceans collected along the coasts of Florida (U.S.A.) and Shimoni (Kenya). Robustunguis gen. nov. is closely related to Coullia Hamond, but differs significantly from the latter because of the remarkable prehensile first leg adapted to clench the bristles covering the body and body parts of the hosts.

Provedor de dados: 16
Autores: Petersen, K.S.
Environmental changes in the Holocene molluscan fauna are elucidated by the investigation of the Korupsø area in the central part of Djursland, Denmark, on macrofossils and 14C datings of shell material. The oldest recorded stratum is a lacustrine Boreal lime gyttja which in the Early Atlantic was covered by saltwater gyttja with a rich fauna of molluscs. The fauna is characterised by Ostrea edulis, Venerupis decussata, Macoma balthica, and Corbula gibba. Bittium reticulatum is only found in large quantities within this older part of the sequence up to the end of the Atlantic. The disappearance of Bittium reticulatum in the Subboreal is explained as having been caused by a change to a more brackish environment. This explanation is supported by the decline...

The development of the fruit-body of Marasmius cornelii (Agaricales) and of a new species of Marasmius sect. Gloiocephala
Provedor de dados: 16
Autores: Corner, E.J.H.
The gymnocarpic development of the very small and gill-less fruit-body of Marasmius cornelii is directed by intrinsic factors until the lengthening stem becomes geotropic. The primordium is covered from a very early stage by a hymenioderm of clavate encrusted cells with a few lanceolate pileocystidia; the smooth clavate cells are a later development from the marginal growth of the pileus. The intercalary formation of the stem separates the pileus from the basal disc which acts as a turgid cushion supporting the stem round its insititious base. The hymenium is microscopically collariate. The Malayan M. poculiformis spec. nov. develops in the same way but lacks the basal disc to the stem which lengthens by secondary septation of its hyphae.

Megapode phylogeny and the interpretation of incubation strategies
Provedor de dados: 16
Autores: Dekker, R.W.R.J.; Brom, T.G.
Among megapodes, several incubation stategies can be recognized. Eggs are incubated by heat generated from microbial decomposition, volcanism, or the sun. For a long time, controversy has existed whether these strategies represent primitive traits, inherited from reptilian ancestors, or have evolved from the 'regular' way of incubation in birds. In this paper these strategies are interpreted by superimposing them on the most recent phylogenetic hypotheses regarding the inter- and intrafamilial relationships of megapodes. We conclude that similarities shared with reptiles and kiwis are due to convergence. Arguments are put forward that mound-building represents the plesiomorphic condition in megapodes and that burrow-nesting has been derived from it....

A manual on the circa 25,000 species of vascular plants that have the peculiar habit of rooting in tree crowns rather than on the ground. Their importance should not be underrated: in some pluvial neotropical forests 30-50% of the vascular flora is composed of them! They create niches for myriads of other organisms, including the majority of the 30+ M species of insects. They thus form an important part of the biosphere and biodiversity, while their biomass and so influence on the atmosphere can rival, if not exceed that of ‘normal’ plants.

In the early thirties the late Polish palaeontologist Wilhelm Krach started the publication of a long series of papers on the mollusc faunas and the biostratigraphy of the Tertiary deposits in Poland, predominantly focusing on the Miocene of the Carpathian Foredeep. In several of these papers holoplanktonic molluscs ('pteropods') are mentioned. Gradually Krach realised the potential value of these organisms in regional and interregional biostratigraphy, resulting in a special paper on the subject, published in 1981. In the present paper a substantial part of Krach's pteropod material, housed in the Institute of Geological Sciences at Kraków, is systematically revised and biostratigraphically interpreted according to modern standards and in accordance with...

First record of a Tachaea species from Sulawesi (Indonesia) with description of its manca stage (Isopoda, Flabellifera, Corallanidae)
Provedor de dados: 16
Autores: Bowman, Thomas E.; Botosaneanu, Lazare.
A corallanid isopod in the manca stage (lacking pereopod 7), collected from alluvial gravel along the Batui River in Sulawesi, Indonesia, and identified questionably as Tachaea lacustris Weber, 1892, is illustrated and described in detail. Tachaea lacustris was known previously only from freshwater lakes in Sumatra and Java. Its presence in river alluvial gravel should not be interpreted as possible adaptation to the hyporheic habitat.

[Proceedings of the symposium 'Molluscan Palaeontology' : 11th International Malacological Congress, Siena (Italy) 30th August - 5th September 1992 / A.W. Janssen and R. Janssen (editors)]: Early rissoid gastropods from the Jurassic of Italy: the meaning of first appearances
Provedor de dados: 16
Autores: Conti, M.A.; Monari, S.; Oliviero, M.
Studies of Jurassic outcrops from Veneto, Central Italy and Sicily improved our knowledge on the gastropods of these areas, characterised by the presence, aside of archaic forms, of some modern ones. Noteworthy is the record from those outcrops of several species, which can be referred to the family Rissoidae (Rissooidea). Formerly, earliest rissoid records were only known from European outcrops of younger age. In the Italian records several species have been recognised belonging to at least two genera of Rissoidae, namely Rissocerithium and Zebinostoma. The presence of such a relatively diversified number of species, bears witness of a well established group. They should have had a common ancestor with the Rissoina-like rissoids of the continental...

[Proceedings of the symposium 'Molluscan Palaeontology' : 11th International Malacological Congress, Siena (Italy) 30th August - 5th September 1992 / A.W. Janssen and R. Janssen (editors)]: Palaeobiogeographical observations on Villafranchian continental molluscs of Italy
Provedor de dados: 16
Autores: Esu, D.; Girotti, O.; Kotsakis, T.
In this paper the palaeobiogeographical affinities of Villafranchian continental molluscan faunas of Italy are examined. The best known Early Villafranchian (= Middle Pliocene) assemblages come from the Piedmont Basin which delivered a rich malacofauna dominated by archaic pulmonates, studied a hundred years ago by Sacco. New sampling in this basin by the authors of this paper have permitted to find some other palaeobiogeographically interesting taxa. Many taxa indicate strong affinities with west-European basins (France, western Germany). In central Italy, recent findings in deposits of the Tiberino Basin (Umbria) have pointed out a good number of Early Villafranchian pulmonate species common to the Piedmont Basin and some endemic aquatic prosobranchs.

Foraminiferal biostratigraphy and palaeoenvironments of the Miocene-Pliocene Carboneras-Nijar Basin (SE Spain)
Provedor de dados: 16
Autores: Poel, H.M. van de.
Five successive, distinct, microfossil assemblages, primarily characterized by their benthic foraminiferal contents, have been recognized in the Mio-Pliocene of the Carboneras-Nijar Basin (SE Spain). The assemblages record a number of fundamental changes in the environment of the area, which have been dated by means of planktic foraminifer biostratigraphy. In the earliest Messinian the central part of the basin was several hundreds of metres deep and had relatively open marine conditions, which were followed by oxygendeficiency, accompanied by slightly deviating salinities and some reduction in waterdepth. Subsequent deposition of Messinian evaporites was interrupted by sparse more open marine sedimentation. During the late Messinian brackish conditions...

The Ascomycete genus Monilinia Honey with its anamorph Monilia includes many parasites of woody perennials, including economically important fruit-trees. This study treats the morphology in vivo and in vitro and detailed life histories; it evaluates, describes and selects criteria for the generic and infrageneric definition of taxa; it discusses host-pathogen interactions, symptoms, nature of losses, extent of host-specificity of the various species, including cross-inoculation work in the greenhouse, and reviews control measures for the eight economically important species. Two dichotomic keys facilitate the identification of the taxa.

Europese en mondiale verspreiding van Nederlandse vaatplanten
Provedor de dados: 16
Autores: Schaminée, J.H.J.; Duuren, L. van; Bakker, A.J. de.
Quantitative information about the distribution of plant species can play an important role in flora and vegetation analyses, for instance in relating distribution figures with floristic and phytosociological data. Therefore, all species of the Dutch flora were classified according to their distribution patterns in six more or less floristic homogeneous regions in Europe. For each region, the coverage of the plant species is given. The distribution outside Europe (but inside the Holarctic) and outside the Holarctic is qualitative. The figures are based on the natural distribution patterns of the species, except for those species that have been naturalized a long time ago and of which the original distribution is unknown (‘archaeophytes’). Apart from that,...

Mate choice in Australian brush-turkeys Alectura lathami : a preliminary report
Provedor de dados: 16
Autores: Birks, S.
Female brush-turkeys respond to several factors when choosing with whom they will mate and where they will lay their eggs. The most important factors seem to be mound condition (especially incubation stage and digging effort required), male presence at mounds (though not necessarily male quality), and perhaps competition with other females for access to mounds. Most visits by females to mounds are for the purpose of copulation and mound "assessment" rather than egg laying. Females visit several mounds/males during the breeding season. Once they make a choice, most remain loyal to the chosen mound/male for several weeks, and are rarely seen at other mounds during this time. When switching to new mounds, females always choose more recently built ones even if...

Polyploidy in Discomycetes
Provedor de dados: 16
Autores: Weber, E.; Bresinsky, A.
Polyploidy is quite a common phenomenon in discomycetes. The ploidy levels have been explored by means of microspectrophotometric determination of the relative nuclear DNA content. In rare cases all the examined species of a genus have the same relative DNA contents, i.e. are to be regarded as belonging to one definite ploidy level. Most genera, however, contain species with different ploidy levels. The lowest measured amount of DNA is presumed to represent the haploid state, which is not very common. The most frequent ploidy levels are diploid, triploid, and to some extent also tetraploids. Higher-ploids occur less frequently. Moreover a correlation between grade of ploidy and period of fructification, substrate type and altitude (or climate) has been...

This symposium volume gives the state of the art in the research on ant-plant interactions. A lot of new data and insights are presented. A thematic grouping of the chapters divides the book into six parts. The first part deals with antagonistic interactions, i.e., the leaf-cutter ants. It appears that leaf-cutters collect a diversity of material, diluting the effect of toxic allelochemicals. They may collect quite inappropriate material; they have been reported to cut and bring back pieces from plastic labels.

Structure and ontogeny of stomata in ferns
Provedor de dados: 16
Autores: Sen, U.; De, B.
On the basis of ontogeny and arrangement of the surrounding cells the stomata in ferns are classified into twenty-four types of which seven – plupolocytic, pseudocopolocytic, sepcopolocytic, pseudohemiparacytic, pluhemiparacytic, pluparacytic and codiacytic – are new. The ontogenetic interrelationships among different stomatal types are traced and the role of stomata in determining the taxonomic position of Psilotum, Tmesipteris and the Ophioglossum group of genera are discussed. It is concluded that the mesogenous and mesoperigenous types of stomata are not distinct entities – one is the derived form of the other. The polocytic stoma which is mesoperigenous in origin is, however, not accepted as the direct descendant of the anomocytic (perigenous) type.

The Palanan Wilderness is a large, circular wildlife reserve encompassing the land and sea within a 45 km radius centered around the Palanan Point in Isabela Province on the northeastern coast of Luzon Island. It was set aside by the Philippine government in 1979 to protect the fast diminishing indigenous fauna and flora of the Sierra Madre Range. Aerial reconnaissance shows that the wilderness consists of a nearly continuous canopy of rain forests extending all the way from the crests of Sierra Madre Range eastwards and downwards to the Pacific Ocean and is minimally interrupted by human settlements along the alluvial plain of Palanan River and a few landing points along the coast. The flora of the Palanan Wilderness is representative of the Sierra Madre...

Autores: Rookmaaker, L.C.
Jean Nicolas Sébastien Allamand (1713—1787), working in Holland, wrote 41 articles about mammals which were not, or only insufficiently, treated by the Count of Buffon in his Histoire naturelle. Allamand’s contributions first appeared between 1769 and 1781 in various volumes of a French edition of the Histoire naturelle published by J.H. Schneider in Amsterdam. These additional articles are analysed to recognize the sources available to Allamand. The new information was mainly derived from animals seen at fairs in Holland, at the inn Blauw Jan in Amsterdam, in the menagerie and museum of Stadholder Willem V near The Hague, in the museum of the University of Leiden, and from observations made in South Africa by R.J. Gordon.

A trend is visible that common species are becoming more common and that rare species are becoming more rare. The floristic decline affects the chalk-rich and nutrient-poor habitats, the progress concerns the nutrient-rich habitats.

Autores: Petersen, Ronald H.; Bermudes, David.
Single-spore and polyspore cultures of Panellus stypticus from Japan were non-luminescent, while single-spore isolates from Illinois comprised both luminescent and nonluminescent strains. Luminous single-spore isolates exhibited varying levels of luminescence, and in some single-spore isolates, a delay in the onset of luminescence was observed. Japanese and eastern North American collections were universally sexually compatible, and thus belong to the same biological species. Nuclear migration beyond the contact zone between crossed single-spore strains was only occasionally observed, and was consistently accompanied by hyphal lysis of the receptor strain. Production of nuclei fit for nuclear migration appeared strain-specific, and not related to mating...

Autores: Achterberg, C. van; Austin, A.D.
A key to all known genera of the Sigalphinae (Braconidae) is given and all genera are described and fully illustrated. Two new genera from the Australian region and one from the Afrotropical region are described: Notosigalphus gen. nov. (type species: Sphaeropyx conjugator Turner, 1917), Aposigalphus gen. nov. (type species: Aposigalphus tessi spec. nov.), and Malasigalphus gen. nov. (type species: Malasigalphus petiolaris spec. nov.). Keys to the Australian and Palaearctic species of Sigalphinae are given. The new tribe Afrocampsini is proposed for the Afrotropical genera Malasigalphus gen. nov. and Afrocampsis van Achterberg &amp; Quicke, 1990. Sigalphus hunanus You &amp; Tong, 1991, and S. anonis You &amp; Zhou, 1991, are synonymized with S. irrorator...

Large numbers of cyclophosphamide- or carrageenan-pretreated immunosuppressed adult ddY mice died within 10 days after inoculation with several species of opportunistic bacteria, including P. aeruginosa, K. pneumoniae, E. coli, S. aureus and methicillin resistant S. aureus. When immunosuppressed mice were administered bacteria in combination with two 100 μg/mouse intramuscular doses of a newly synthesized peptide, Obiopeptide-1 (OP-1), survival rates increased significantly. At 24 and 48 hours after intraperitoneal inoculation with P. aeruginosa, counts of viable organisms from the livers, spleens, lungs, hearts, and kidneys of mice that were administered cyclophosphamide in combination with OP-1 were significantly lower than counts from mice that were...

Genomic Analysis of Sarcocystis by Contour-clamped Homogeneous Electric Fields
Provedor de dados: 19
Autores: Su, Hung-Yi; Tenter, Astrid M.; Johnson, Alan M.
The chromosomal DNA of Sarcocystis gigantea and Sarcocystis muris were digested with NotI and SfiI and characterized in contour-clamped homogeneous electric fields. Under these electric fields, the chromosomal DNA of S. gigantea and S. muris showed different electrophoretic mobilities. Therefore, it appears that this technique may be useful in future studies on the differentiation of Sarcocystis species. The results of NotI and SfiI digestion of S. muris chromosomes suggested that there is an absence of a significant number of recognition sites for these two enzymes in the genome of S. muris. The addition of the sizes of 15 SfiI fragments of S. gigantea DNA suggested that the S. gigantea genome is larger than 14 mb.

Autores: Claveria, Florencia G.; Omata, Yoshitaka; Takehara, Tokuma; Saito, Atsushi; Maki, Yoshiyuki; Igarashi, Ikuo; Suzuki, Naoyoshi.
Anti-Babesia rodhaini monoclonal antibodies (mAb), namely: 1-E7, 2-H2 and 3-B8, significantly suppressed the development of high parasitemia in BALB/c mice infected with B. rodhaini and all mAb-treated mice survived the infection. While, only monoclonal antibody 3-B8 showed some inhibitory effect against Babesia microti, with mice showing high parasitemia of 18.04 ± 2.69 %, at 9 days post-exposure. Westernblot analysis of B. rodhaini and B. microti parasite extract reacted with anti-B. rodhaini monoclonal antibodies showed cross-reactive bands of molecular weights 62 and 55 kilodaltons. Comparison of the antigenic components of B. rodhaini and B. microti using polyspecific sera revealed several shared or common parasite antigens of molecular weights 62,...

Monoclonal Antibodies Prepared against Theileria annulata-infected Bovine Cells Recognize an Infection-associated Antigen Expressed by the Infected Cells
Provedor de dados: 19
Autores: DÖrflinger, W.; Schein, E.; Ahmed, J. S.
A battery of monoclonal antibodies were produced in mice against Theileria annulata-infected cells. Two of these antibodies (IgM and IgG1) reacted specifically with the surface membrane of the infected cells but not with Con A-stimulated or unstimulated bovine peripheral blood lymphocytes (PBL). The antibodies could stain also clones which were derived from the cell lines tested in the present study. Similarly, they reacted with T.annulata-infected but not with uninfected sheep PBL. After removal of the parasites by treating the infected cells with the anti-theilerial drug buparvaquone, the antibodies were no more able to bind to the cells.

Autores: Ishibashi, Kenichi; Day, Donald L; Zhang, Ruihong; Hironaka, Kazunori; Koaze, Hiroshi.
Fuel, feed, and fertilizer are critical resources that often must be imported. Especially for agriculturalists in developing countries, the high cost of these resources and high interest rates create significant economic problems.     These economic problems, the decreased availability of renewable sources of fuel, and the need for pollution control and fertilizer conservation have forced people to look for new sources of these resources. Methane fermentation technology is one alternative that has received widespread interest in developing countries because it converts locally available byproducts into fuel, feed, and fertilizer. Through a microbial process, agricultural waste material and byproducts can be converted into valuable products. This conversion...

Provedor de dados: 19
Autores: Tan-Ariya, Peerapan; Chetanond, Usa; Brockelman, Charia R.
Four culture lines of Babesia bovis Thai strain were successfully established in this study. The results of the in vitro microtest for their sensitivities to quinuronium sulfate revealed that all the culture lines were similarly drug responsive. The 50% inhibitory concentrations for the four culture lines were found to be within the same range, varying from 1.72x10-6 to 2.43x10-6 g/ml. One resistant line TS-2R selected from the drug-treated culture had an IC50 of 1.71x10-5 g/ml which was 7 times higher than that of its original isolate TS-2.

Antigenic Diversity among Oocysts of Clinical Isolates of Cryptosporidium parvum
Provedor de dados: 19
Autores: Griffin, K.; Matthai, E.; Hommel, M.; Weitz, J. C.; Baxby, D.; Hart, C. A.
A panel of monoclonal antibodies has been produced against the protozoan parasite Cryptosporidium parvum which is a major cause of diarrhoeal disease in man and other animals. C. parvum oocysts from both a human and a bovine case of cryptosporidiosis were used as immunogens. A total of 11 different monoclonal antibodies were obtained which could bind to formalin-fixed oocysts. One was IgA but the remainder were all of IgM isotype. The reactivity of these monoclonal antibodies against a series of C. parvum oocysts obtained from 25 patients in Chile was examined using indirect immuno-fluorescence. Although a mixture of all of the 11 antibodies would have detected oocysts in each of the samples, no one monoclonal antibody recognised all oocysts. Each antibody...

The change in the viscoelasticity of the Chinese yam during growth was investigated from mid-August to late November, 1988 in the Tokachi district of Japan. The Chinese yam had peak viscoelasticity around October 24. Its viscosity was correlated with the insoluble solid content, whereas its rigidity was associated with the mucilage content. Viscosity and rigidity values of Chinese yam during maturation reached maximum when the soil temperature at 40 cm decreased to around 11 centigrade.

A Review of the Taxonomy of Theileria sergenti/buffeli/orientalis Group Parasites in Cattle
Provedor de dados: 19
Autores: Fujisaki, Kozo.
The controversial circumstances relating to the classification of the benign Theileria species from Japan, Australia and Britain, which are frequently referred to as T. sergenti/buffeli/orientalis group parasites, was reviewed. Our recent systematic comparisons suggest a possibility that the Japanese T. sergenti (minor piroplasm in common parlance) might be a new species and the Australian T. buffeli and British T. orientalis might belong to one and the same species. The necessity for the review of the genus name for these benign Theileria species was also briefly discussed after the morphological studies of their schizogony.

Mononuclear cells, CD2+ T cells and T subsets (CD4+, CD8+) from HLA-typed malaria-naive donors were stimulated with isolated surface antigens (Ags) from Plasmodium falciparum merozoites (MSP183, MSP136, MSP2). Cell responses in lymphocyte proliferation assays were MHC-class II and mainly DR restricted. Donors could be grouped into high, non or low responders according to the proliferative response. The high responders possessed the combination DR7/DRw53 as a common HLA-restriction element. Non and low responders did not have this Ag combination, but some were characterized by DQwl. Individual donors did not show any Ag dependent response. CD45RA+ (naive, non-stimulated) enriched T cells from high-responders were strongly stimulated by the merozoite Ags,...

Therapeutic effects of Toxoplasma lysate antigen (TLA) were studied in mice bearing the tumor in the second passage of 20-methylcholanthrene (MC)-induced tumor cells. Intramuscular administration of TLA 7 days after the tumor-cell inoculation caused apparent inhibition of the tumor growth on day 14. The second treatment facilitated the therapeutic effects. Intravenous transfer of spleen cells prepared from TLA-sensitized mice into tumor-bearing mice also represented the growth inhibitory effects. Prominent effects were seen when the transferred cells were prepared 5 days after sensitization of donor animals. The inhibitory effects were absent in the groups transferred only the adherent cells or the non-adherent cells prepared from sensitized mice. The...

In order to identify mechanisms responsible for the anti-tumor effects of Toxoplasma lysate antigen (TLA), we used an in vitro 51Cr release assay to study the functional properties of plastic-adherent cells during induction of splenic cytotoxic activity by TLA. Cytotoxic activity of non-adherent cells was measured in all experiments after a 6 days incubation. Induction of cytotoxic non-adherent cells by TLA required the presence of plastic-adherent spleen cells. In contrast, rhIL-2 alone was able to induce transformation of cytotoxic non-adherent cells from non-adherent spleen cells. Contact between adherent and non-adherent spleen cells was necessary for successful induction of cytotoxic non-adherent cells by TLA. Treatment of spleen cells with...

Spleen cells from Toxoplasma lysate antigen (TLA)-sensitized BALB/c mice showed the strong cytotoxic activity against both natural killer (NK)-sensitive cells (YAC-1 and RL♂-1) and NK-insensitive cells (P-815), when incubated with TLA or recombinant human IL-2 (rhIL-2). The increment of TLA concentration in culture medium increased the cytotoxic activity. Treatment of effector cells; spleen cells from TLA-sensitized mice incubated with TLA, with anti-asialo GM1 or anti-Thy-1 plus complement inhibited the cytotoxic activity of effector cells, whereas treatment with anti-mouse Lyt-2.2 serum plus complement had no effect on the cytotoxic activity. Treatment of spleen cells from TLA-sensitized mice with anti-asialo GM1 and/or anti-Thy-1 plus complement...

Autores: Torii, Motomi; Aikawa, Masamichi; Indsrivastava, Resh K.; Schmidt, Maurice; Nakamura, Kei-Ichiro; Perrin, Luc H.
The expression of a Plasmodium falciparum 41 kDa blood stage antigen (p41) was followed by examining both protein level and aldolase activity in synchronized cultures. The protein and enzymatic levels were low in erythrocytes containing ring forms, and increased markedly with the appearance of trophozoites and young schizonts. The subcellular localization of p41 aldolase was determined using immunoelectron microscopy with rabbit anti-p41 and anti-recombinant p41 antisera. P41 was localized within the cytoplasm of P. falciparum extracellular merozoites, trophozoites and schizonts.

A Review of Neospora caninum and Neospora-like Infections in Animals
Provedor de dados: 19
Autores: Dubey, J. P.
Neospora caninum is a recently recognized protozoan parasite of animals. Until 1988, it was misdiagnosed as Toxoplasma gondii. Neospora caninum or Neospora-like parasites cause paralysis and death in dogs and neonatal mortality and abortion in cattle, sheep, goats and horses. Its life cycle is not known. Tachyzoites and tissue cysts are the only asexual stages known and the carnivorous definitive host is not known. Transplacental transmission is the only known natural route of infection.

Growth of the tumor autoinduced by 20-methylcholanthrene (MC) in rats was inhibited after administration of Toxoplasma lysate antigen (TLA). The antitumor activity of TLA was most obvious in the early stage of tumoral growth. When TLA was administered to rats before the appearance of tumor, tumor formation was delayed slightly. Histopathological studies revealed dense growths of spindle tumor cells in untreated control rat, while enlarged central necrosis with the infiltration of lymphocytes and neutrophils was apparent in TLA-treated rats. According to the immunohistological examination of tumor tissue with anti-Thy-1 antibody, the rats treated with TLA showed large Thy-1 positive granular cells, whereas the untreated rats indicated only a few small Thy-1...

Observations by Scanning Electron Microscopy of Surface Events during Encystment and Excystment in Gastrostyla steinii (Cliophora, Hypotrichida)
Provedor de dados: 19
Autores: Knaippe, Fatima; Tetley, Laurence; Mullin, Margaret.
The surface of the protozoan Gastrostyla steinii undergoes profound morphological changes during the encystment and excystment processes. Resorption of the various ciliary structures occurs progressively during differentiation of the free living cell into the resting cyst. In ciliar disassembly, layers of the cyst wall are deposited on the surface of the encysting organism. At excystation, the hatching trophozoite emerges from the protective wall through a cleft after the formation of the ciliary organelles.

Epitopic Specificity of the Human Immune Response to the Invariant Region of a Polymorphic Plasmodium faciparum Merozoite Surface Antigen
Provedor de dados: 19
Autores: Rzepczyk, C. M.; Anderson, K. L.; Crurshes, P. A.; Baxter, E. P.; Kere, N.; Irving, D.; Dyer, S.; Jones, G. L.
Merozoite surface antigen 2 (MSA2) is a Plasmodium falciparum vaccine candidate. Antibody responses to MSA2 in Melanesians naturally exposed to P. falciparum were investigated by ELISA using the recombinant MSA2 protein known as Ag 1609 and 65 overlapping synthetic peptides spanning predominantly the conserved N and C terminal regions of MSA2. Significant differences were obtained between control and malaria exposed subjects in the ability of sera to bind to Ag 1609. The median absorbance obtained with control sera was 0.36 whereas that obtained with sera from malaria exposed subjects was 1.8. The sera of ninety-five percent of malaria exposed subjects reacted significantly with Ag 1609. The percentage reactivity of the control sera with Ag 1609 was 39%....

Situación actual y perspectivas del recurso Macarela (Scomber japonicus) en Ecuador
Provedor de dados: 20
Autores: Santos, M.; González, N.
Los marcados cambios en la disponibilidad de macarela (Scomber japonicus) en aguas ecuatorianas debido a su migración, se relacionan probablemente con las modificaciones en el medio ambiente, que determinan las condiciones óptimas para la alimentación, reproduccion y sobrevivencia larval (French y Men, 1983). En general, las capturas de Macarela presentan una clara estacionalidad con dos periodos de máximos desembarques: enero-marzo y agosto-octubre. Entre los años 1982 y 1991 las capturas alcanzaron un máximo de 590000 t (1982) y un mínimo de 84000 t (1991), con un promedio anual de 262000 t. Las capturas anuales en el período analizado (1982-91) muestra un contínuo descenso, caracterizado por escasos volúmenes obtenidos durante los eventos ”El Niño” (EN)...

Los lenguados constituyen un importante recurso pesquero en el Mar Argentino. Más que en los volúmenes desembarcados (9 .731 t en 1991), esta importancia se centra en su elevado valor de comercialización debido a la alta calidad de su carne. Atendiendo a los desembarques totales realizados en el Mercado de Concentración Pesquera de Mar del Plata, los lenguados ocupan el octavo lugar. Estos desembarques están compuestos principalmente por especies de porte mediano a grande pertenecientes al género Paralichthys, y por ejemplares de tamaño mediano o pequeño de las especies Xystreuris rasile, y en menor proporción, Paralichthys isosceles. Este recurso es explotado, en el sector bonaerense, por las flotas de rada o ría y costera, mientras que la flota de altura...

Seychelles tuna bulletin: First quarter 1992
Provedor de dados: 20
The number of purse seiners active in the western Indian Ocean averaged 53 during the first quarter compared to 41 vessels during the same period last year.  Fishing activity was high during the first half of the year with a record for the month of March of 55 licensed vessels. The fishing results for the first quarter were not as good as those previously recorded in the last three years, however there are still 28 logbooks outstanding at the time of publication.  Catch rates averaged 14.6 MT/day compared to 22MT/day in 1991 and 26MT/day in 1990.  The high number of vessels licensed during the first quarter can be attributed to increased number of licenses issued to French and Japanese vessles. 1992 has been a notably strong El Nino year, giving rise to a...

Autores: Espín, S.M.; Nath, J.
Un estudio de las características del régimen del oleaje en la isla San Cristóbal fue realizado durante el período comprendido entre diciembre de 1990 y diciembre de 1991. Los datos fueron obtenidos con un sensor de presion instalado en el veril de 9 m. en Bahía Naufragio, obteniéndose un registro de 2436 datos de alturas significativas y períodos medios. Del análisis de las series de alturas, períodos y los vientos de la región se determinó que las olas registradas corresponden a un régimen estacional ya que las de mayor altura y menores períodos se presentaron durante la época seca (de Mayo a Septiembre), con la intensificación de los vientos del sur y sureste, y las de menor amplitud y grandes períodos en la época húmeda. El arrecife de Schiavoni que se...

Results of a spiny lobster survey around Mahe Island during September and October 1991
Provedor de dados: 20
Autores: Bautil, B.R.R.
Spiny lobster fishing in the Seychelles is an artisanal done essentially by skin divers operating at night in the shallow waters surrounding by the islands. Because of human population distribution lobster fishing grounds are concentrated on the inner granitic islands. In September 1992, a random stratified samoling program was set up to gather biological information from the entire granitic Mahe plateau. Direct census of fishery resources by Scuba divers swimming underwater transects was selected as the most feasible and expedient means by which to enact the Resource Survey. This report present partial result gathered for the survey around Mahe Island only and provides an estimate of the Maximum sustainable yield for the granitic plateau by extrapolation...

Cottage level production of fish meal
Provedor de dados: 20
Autores: Akande, G.R.; Simpa, J.
Fishmeal is a vital component used in animal feed formulations. The present status of fisheries industry in Nigeria is mainly artisanal. The artisanal sector contributes over 90% of the total landing while the industrial sector contributes less than 10%. The artisanal sector is thus a potentially huge source of fish meal. Possible source of raw materials for fish meal production at cottage level includes artisanal seasonal glut and waste from the consumption industry.  These two sources cannot sustain the setting up of fish meal plant on a large scale.  A method to produce fish meal from artisanal fishing activities and waste from canning industry was investigated using simple processes of cooking, pressing and drying. The fish meal produced by direct...

Autores: Santos, M.; Fuentes, E.
A partir de 1990 y debido a la drástica reducción en la abundacia de los recursos Sardina (Sardinops sagax) y Macarela (Scomber japonicus) las embarcaciones de la clase 3 también dirigieron su esfuerzo hacia la captura de Pinchagua. Los patrones de las capturas mensuales de los últimos diez años presentan una cierta estacionalidad con mayores capturas entre mayo y agosto. Las tendencias de las capturas anuales entre 1982-1991 han mantenido un comportamiento irregular influenciado por eventos cálidos EL Niño (EN) y un pulso de abundacias y de altas capturas. Durante el periodo analizado (1982-1991) la captura promedio fue de 186562 t. Las máximas capturas se registraron entre 1985 y 1986 y fueron superiores a las 325000 t/año; un brusco descenso ocurrió en...

La pesquería de especies pelágicas en Ecuador
Provedor de dados: 20
Autores: Aguilar, F.
Entre las principales especies pelágicas costeras que tradicionalmente han sido capturadas por la flota cerquera del Ecuador están: Sardina del sur (Sardinops sagax), Macarela o Morenillo (Scomber japonicus), Pinchagua (Opisthonema spp.), Chuhueco (Cetengraulis mistycetus), Sardina redonda (Etrumeus teres). Las embarcaciones utilizadas son del tipo Purse Seiner. Este artículo muestra un análisis de la tendencia de las capturas obtenidas entre 1982 y 1991, lo que permite apreciar con claridad que posterior al máximo obtenido en 1985, las capturas descendieron significativamente como consecuencia en la reducción en la abundancia de Sardina y Macarela, lo que se explica por los efectos negativos de un intenso esfuerzo pesquero y de condiciones oceanográficas...

As pan of the EROS-2000 project (European River Ocean Systems),sediment samples were collected in the North Western basin of the Mediterranean Sea in May 1990. In these samples trace and/or majorelements were determined to advance the knowledge about theconcentration, sources and cycles of natural and anthropogenicconstituents in coastal areas. Three fractions were determined: the porewater fraction whichcontains all dissolved elements the leachable fraction which containsall easily available elements and the residual fraction which containsthe strongly bound elements in the sediments. The results show thatthe investigated area can be separated into five "sub-areas" which aredifferent in element concentration, leachable fraction andsedimentary composition....

Seychelles demersal fishery an analysis of data relating to four key demersal species
Provedor de dados: 20
Autores: Mees, C. C.
Seychelles demersal fishery is described based on historic catch and effort data, and on biological studies of four key species: Batrican (Pristipomoides filamentosus), Job Gris (Aprion virescens), Bourgeois (Lutjanus sebae), and Maconde (Epinephelus chlorostigma).  During the period 1985 - 1990 demersal species formed on average 33_310= of the total annual landings of the local fishing fleet.  Schooners and whalers were the most important boat types engaging in this fishery, and more recently, a mother ship dory fishing operation. Demersal species constituted 77_310= of all local fish exports over this period. In 1990 approximately 2,000 tonnes of demersal species were landed of which 500 tonnes were exported.  Lutjanids comprised 62_310= of the demersal...

Forty oyster spat collector bags were submerged at two different sites near Mahe island fofr a period between 3.2 and 11 months. Strong currents in the south-east monsoon period resulted in a few bags lying in the sand which was detrimental to spat settlement. The mean settlement rate was calculated at 15.6 oysters per bag, however 71_310= of the bags had more than 10 oysters per bag. Considering only those bags, the settlement averaged at 27 oysters per bag. The sizes of oysters in collector bags after different soaking times, indicate that growth rate in the first few months is higher than on French Polynesia. Growth rates of oysters maintained in a cage indicated an average increase of 21.7 mm in five months, between the size of 25.9 mm and 47.76 mm....

Implications of Expected Climate Change in the Eastern  African Coastal Region: an Overview
Provedor de dados: 20
Autores: Ogallo, L.J.; Alusa, A.L.
Anticipated global warming as a result of the emission of greenhouse gases into the atmosphere was the most important subject discussed during the fifteenth session of the Governing Council of UNEP and at the Second World Climate Conference. The so-called greenhouse effect is a most pressing environmental problem to the extent that it involves many scientific disciplines and hence presents major challenges. The greenhouse gases (CO2,' CFCs, CH4, N2O, O3, etc.) have the effect of changing the atmosphere's radiative balance by trapping more heat near the earth's surface resulting in a rise in global mean surface temperature. It is now clear that if the burning of fossil fuel continues at the present rate, global warming is a virtual certainty.

Qualitative clay mineralogy of the Middle and Upper Eocene in north-western Belgium
Provedor de dados: 27
Autores: Jacobs, P.; De Coninck, F.
Detailed chemical and X-ray analysis of representative clay fraction samples from the Maldegem and Zelzate Formations (Middle and Upper Eocene) in western Belgium reveal a rather constant clay mineralogy, consisting mainly of kaolinite, smectitic minerals (of the nontronite type) and illite. Glauconite occurs in two different forms, the coarser grained being better crystallized. Local climatic or landscape conditions as inferred from the qualitative clay mineralogical suite point towards a shallow marine sedimentary environment in transgressive phase. A low relief restricted drainage area delivered kaolinite to the basin under moderate weathering conditions, transforming volcanic ash layers into smectites.

Ecological approach of macro-fouling prevention and control in cooling systems
Provedor de dados: 27
Autores: Denayer, B.; De Ranter, K.; Van Poele, J.; Ollevier, F.P.
Biofouling is a very frequent and serious problem in the cooling systems of electrical power stations. An investigation is being carried out at the Doel nuclear power station to discover ways of combating micro-fouling. Micro-fouling is combated preventively and curatively using a combination of chlorine, biofilm wetting agent and dispersing agent. This treatment removes the slime layer, which can act as a primary attachment point for macro-organisms.In the study of the macro-fouling in the cooling circuits, a monitoring method was developed which uses artificial substrates to provide direct data on the colonization and growth of these organisms. On the basis of the data obtained, the treatment frequency for the prevention or combating of biofouling was...

Wind en golven: onderzoek van een optimaliserings-benadering voor het schatten van parameters in de brontermen = Wind and waves: investigation of an optimization approach to parameter estimation
Provedor de dados: 27
Autores: Monbaliu, J.
The atmosphere sees the ocean, with sometimes huge waves, as a much smoother surface, compared to its passage over land where it is slowed down much more, even if obstacles are small compared to the size of ocean waves. A good observer notices right away that waves travel with the wind and consequently do not give much resistance. The details of how much resistance there actually is and its variation with wind speed and parameters defining the wave conditions has been a hot topic for the last 35 years. The correctness of the roughness formulation is a crucial question in the understanding of the air-sea interface. It has major implications in wave modelling, in storm surge modelling and also in modelling of the atmospheric boundary layer above the ocean....

Structural analysis of the meiobenthos communities of the shelf break area in two stations of the Gulf of Biscay (N.E. Atlantic)
Provedor de dados: 27
Autores: Vanreusel, A.; Vincx, M.; Van Gansbeke, D.; Gijselinck, W.
In a first attempt to obtain information in order to characterize the shelf break zone, the meiobenthos communities of two fine sandy stations of 190 m and 325 m depth in the Gulf of Biscay off the Spanish coast were investigated in relation to some environmental characteristics (sediment composition, chlorophyll &lt;i&gt;a&lt;/i&gt; content, redox values). The nematodes, which are the dominant taxon, were studied in detail. Their communities are relatively poor in densities (840 and 779 individuals per 10cm&lt;i&gt;2&lt;/i&gt; and biomass (0.137 and 0.334mg dwt/10cm&lt;sup&gt;2&lt;/sup&gt;) compared to those of shallow coastal areas. The dominance of small species (mean individual biomass: 0.169 and 0.423 µg dwt) and a low total biomass can be related to...

Provedor de dados: 27
Autores: Huys, R.; Boxshall, G.A.; Böttger-Schnack, R.
Males of the two known species of Mormonilla Giesbrecht are described in detail for the first time. They have reduced or vestigial mouthparts and are probably non-feeding. Males have a single testis and produce a single spermatophore. Male antennules are geniculate. A system of probable segmental homologies for the antennulary segments is proposed and the supporting evidence for this system discussed. Females carrying egg sacs are reported and figured for the first time. Mormonilla is unusual amongst copepods in producing paired egg sacs from a common medial genital aperture.

Provedor de dados: 27
Autores: Huys, R.; Andersen, P.; Kristensen, R.M.
Three free-living tantuli of a new genus and species, Tantulacus hoegi, were discovered among the meiofauna from deep carbonate shell-sand on the Faroe Bank. The host-is unknown. Tantulacus is referred to the Deoterthridae on account of its larval characters. It occupies an intermediate positon between Deoterthron - Aphotocentor and the other deoterthrid genera. It can be readily distinguished from other tantulocaridans by -the- pr.esence of a distinct rigid spine on the endopod of the second to fifth thoracopods. Some aspects of the deoterthrid stylet are discussed. T. hoegi is the fourth tantulocaridan described from the temporary meiobenthos.

Effect of salinity on the uptake of cadmium by the brine shrimp &lt;i&gt;Artemia fransiscana&lt;/i&gt;
Provedor de dados: 27
Autores: Blust, R.; Kockelbergh, E.; Baillieul, M.
The effect of salinity on cadmium uptake by the brine shrimp &lt;i&gt;Artemia fransiscana&lt;/i&gt; was studied in chemically defined saltwater solutions. Shrimp were acclimated to different salinities and exposed to the metal in solutions of differing salinity and composition. Within each acclimation group, the cadmium uptake decreased with increasing salinity of exposure. Most of this variation was explained by changes in the activity of the free metal ion. Among the acclimation groups, uptake increased by increasing salinity of acclimation. Most of this variation was explained by changes in the permeability of the shrimp. Uptake was not influenced by changes in the osmolarity or the concentration of any of the major cations in the solution. The...

The use of algal substitutes and the requirement for live algae in the hatchery and nursery rearing of bivalve molluscs: an international survey
Provedor de dados: 27
Autores: Coutteau, P.; Sorgeloos, P.
The mass-production of micro-algae has been recognized by several authors as the main bottle-neck for the culture of bivalve seed. This has prompted a search for alternatives to on-site algal production, such as dried heterotrophically-grown algae, preserved algal pastes, micro-encapsulated diets, and yeasts. However the extent to which these products have been tried, and rejected or retained by hatchery operators is poorly documented. Also, the actual algal requirement and production cost of the bivalve seed industry is difficult to estimate.The present inquiry allowed the collection of data concerning the requirement of live algae and its associated costs encountered in 50 commercial and experimental hatcheries from all over the world. Furthermore, the...

Autores: Chen, H.-Y.; Leu, Y.-T.; Roelants, I.
Effective dietary supplementation of arginine was demonstrated in juvenile &lt;i&gt;Penaeus monodon&lt;/i&gt; which can not effectively utilize crystalline amino acids in their diets. In an 8-week feeding trial, juvenile &lt;i&gt;P. monodon&lt;/i&gt; (average body weight, 0.95 g) were fed casein-based purified diets supplemented with cellulose-acetate-phthalate (CAP) microencapsulated L-arginine, or glycerol-mono-stearate (GM) microencapsulated L-arginine. There was no significant difference in the growth-promoting effects and feed conversion among the CAP, FM and SAL groups. The mean final weight of shrimp fed the crystalline-arginine supplemented diet was higher than that of the group fed the unsupplemented diet but the difference was not significant....

Autores: Xhoffer, C.; Wouters, G.; Van Grieken, R.
Five pairs of North Sea bulk waters and their corresponding surface microlayer samples were investigated for their particulate matter content and chemically analyzed and characterized by electron probe X-ray microanalysis and laser microprobe mass analysis. Multivariate techniques as hierarchical and nonhierarchical clustering in association with principal component analysis was performed on a data set containing more than 3,000 individual particles. This classification procedure yielded eight different particle types. Differences in particle type abundances for the microlayer and bulk water were observed. They were apportioned to their most probable sources. The results were compared with atmospheric and riverine particle data. The domination of the major...

A simple test for quality evaluation of cultured fry of marine fish
Provedor de dados: 27
Autores: Dhert, P.; Lavens, P.; Sorgeloos, P.
A stress test is proposed for the evaluation of the physiological condition of fish larvae in nutritional studies. The test was used in a study of quantitative (n-3) highly unsaturated fatty acids (HUFA) requirements in larval &lt;i&gt;Lates calcarifer&lt;/i&gt; and &lt;i&gt;Siganus guttatus&lt;/i&gt;. It enabled to suggest fast intervention at reduced larval quality and allowed to prevent mass mortalities. The stress test offered valuable information for the quantification study of fatty acid requirements in marine fish larvae. In &lt;i&gt;Lates&lt;/i&gt; demands for fatty acids were detected in metamorphosis. In &lt;i&gt;Siganus&lt;/i&gt; on the other hand, the sensitivity of the larvae was considerably reduced after short (n-3) HUFA boosting of the...

Spatial community structure of the winter hyperbenthos of the Schelde estuary, the Netherlands, and the adjacent coastal waters
Provedor de dados: 27
Autores: Mees, J.; Hamerlynck, O.
A first assessment of the ecological importance of the hyperbenthic fauna in coastal and estuarine systems was made in December 1988 in a pilot study (41 stations) covering the Westerschelde and Oosterschelde estuaries, and part of the neighbouring shallow coastal area, the Voordelta. Multivariate analysis revealed three major gradients which could be divided into seven spatially defined hyperbenthic communities. Canonical Correspondence Analysis was applied to correlate these species assemblages with a number of environmental variables measured at each station. Species distributions in the Westerschelde appear to be primarily determined by a gradient involving salinity, turbidity and dissolved oxygen. Hyperbenthic animals, mainly the mysid...

Autores: De Wachter, B.; Blust, R.; Decleir, W.
Bioavailability of oxygen for the saline-water invertebrate &lt;i&gt;Artemia franciscana&lt;/i&gt; was studied, since both oxygen concentration and oxygen diffusion rate change with salinity. Total haemoglobin concentration and the relative contribution of each of three haemoglobins was measured in specimens acclimated to different salinities and oxygen concentrations. Both haemoglobin concentration and contribution were influenced by salinity and the group observed (males, females with and females without eggs). Multiple regression analysis showed that total haemoglobin concentration was better correlated with oxygen concentration than oxygen partial pressure. The relative proportions of haemoglobins 1, 2 and 3 were better correlated with oxygen partial...

Using microencapsulated L-arginine, the quantitative requirement for amino acids has been determined for the first time for a shrimp species, which can not effectively utilize crystalline amino acids. In an 8 wk feeding trial (1990), juvenile &lt;i&gt;Penaeus monodon&lt;/i&gt; were fed casein based purified diets containing one of six levels (13.1, 17.7, 22.3, 26.9, 31.5 and 36.1 g/kg diet) of arginine. In addition to the protein-bound arginine already present in the casein of the test diets, pure arginine was supplemented by L-arginine microencapsulated in cellulose acetate phthalate, which is easily assimilated. The arginine level required for optimal growth was determined by broken-line model analysis of weight gain data to 25.0 g/kg diet (= 54.7 g/kg...

The use of manipulated baker's yeast as an algal substitute for the laboratory culture of &lt;i&gt;Anostraca&lt;/i&gt;
Provedor de dados: 27
Autores: Coutteau, P.; Brendonck, L.; Lavens, P.; Sorgeloos, P.
The production of unicellular algae is laborious and is a major constraint for the culturing of aquatic filter-feeders. Because of their small particle size and their high protein content yeasts are considered as a promising substitute for micro-algae. Furthermore, recent work has shown that baker's yeast can be converted into a digestible diet for &lt;i&gt;Artemia&lt;/i&gt; by chemical treatment. The present study documents the use at laboratory scale of this manipulated yeast as an algal substitute for the culture of two anostracan species.The experiments were conducted with the brine shrimp &lt;i&gt;Artemia franciscana&lt;/i&gt; and the fairy shrimp &lt;i&gt;Streptocephalus proboscideus&lt;/i&gt;.

The live food enrichment technique using emulsions for nutritional deficiencies in rotifers and &lt;i&gt;Artemia&lt;/i&gt; was further investigated as a tool for transferring therapeutics through the food chain. &lt;i&gt;Artemia&lt;/i&gt; nauplii and the rotifer &lt;i&gt;Brachionus plicatilis&lt;/i&gt; were enriched with a self-emulsifying concentrate in which the therapeutic mixture trimetoprim: sulfamethoxazole was incorporated. An analytical method and protocol for the quantification of trimethoprim and sulfamethoxazole in a heterogeneous biological matrix, such as &lt;i&gt;Artemia&lt;/i&gt; , was developed using High Performance Liquid Chromatography. When applying a 24h enrichment period, the accumulation of both drugs in &lt;i&gt;Artemia&lt;/i&gt;...

Community structure and functional roles of meiofauna in the North Sea
Provedor de dados: 27
Autores: Heip, C.H.R.; Huys, R.; Alkemade, R.
Knowiedge on community structure of North Sea meiofauna has greatly increased recently. A quasisynoptic picture of meiofauna densities and copepod community structure from 171 stations of the southern North Sea, sampled in April–May 1986, has been obtained during the North Sea Benthos Survey. Latitudinal patterns in meiofauna abundance and copepod weight, abundance and diversity exist in an area between 51°30'N and 58°30'N. Using TWINSPAN-classification five major groups of copepod species can be recognized which are related to sediment type, latitude and depth. The part of the meiofauna in total benthic energy flow, their role in the benthic food web and in biogeochemical cycles is discussed based on existing literature. There are still considerable gaps...

Autores: Lein, I.; Gulbrandsen, J.; Holmefjord, I.; Refstie, T.; Bolla, S.; Olsen, Y.; Reitan, K.I.; Vadstein, O.; Øie, G.; Harboe, T.; Sorgeloos, P.
The main goal of the project is to develop intensive industrial scale production systems for halibut fry. Halibut eggs were obtained from three brood stocks both by stripping and by natural spawning. Photoperiod manipulation is used to increase the spawning period, and spawning now takes place in the period February to June/July. The eggs are disinfected and incubated in up-stream conical tanks (8°C, darkness) and transferred to larval incubators after hatching. Two incubator-types are used; small glass bowls (3 liter), run stagnant or semi-stagnant, or large conical silos (0.7-15m³) run with continuous water flow (4-8°C, darkness). These different systems can be used to bring the yolk sac larvae of halibut up to the stage of first feeding. The yolk sac...

Autores: Thomas, K.; Ollevier, F.P.
Eels were sampled twice a month (March 1990 though March 1991) at the Kolenhaven (Albertcanal, Genk, Belgium) and examined for &lt;i&gt;Anguillicola crassus&lt;/i&gt; nematodes in the swimbladder. Averaged over all samples, 90.2% of the 345 eels were infected with a mean intensity (averaged for all stages) of 17 nematodes. Thirty-one percent of all nematodes, which were adult worms or their remnants, were present in the swimbladder lumen, while the other 69% which consisted of the third or fourth larval stage and preadults were found in the swimbladder wall. No clear seasonal fluctuations in parasite prevalence or mean intensity were observed. Both L&lt;sub&gt;3&lt;/sub&gt;-larvae and mature adult worms were present throughout the year. Eggs or...

Electron microprobe characterization of individual aerosol particles collected by aircraft above the Southern Bight of the North Sea
Provedor de dados: 27
Autores: Rojas, C.M.; Van Grieken, R.
About 50,000 individual aerosol particles from a total of 108 samples collected at six different altitudes above the Southern Bight of the North Sea. Have been analysed using electron probe-X-ray microanalysis. The results of hierarchical cluster analysis on each sample revealed that, for continental air masses, most of the aerosol particulate matter is characterized by high amounts of aluminosilicates, CaSO&lt;sub&gt;4&lt;/sub&gt; and Fe-rich particles. For western and marine air masses there was no change in the composition of the most abundant particle type with height. This is in connection with the rather mixed nature of the atmosphere. Non-hierarchical cluster analysis showed that the most abundant particle types in this airshed are: aluminosilicates...

Geochemistry of suspended matter from the Baltic Sea: 2. Results of bulk trace metal analysis by AAS
Provedor de dados: 27
Autores: Brügmann, L.; Bernard, P.C.; Van Grieken, R.
In 1984, on a transect covering the whole Baltic Sea and parts of the adjacent North Sea, 160 water samples were taken and analysed for their concentrations of particulate and dissolved metals. In addition, the suspended materials were investigated for their elemental bulk composition.The particulate fractions represented from about 5% (Cd, Cu and Ni) to 50% (Fe and Pb) of the total (particulate plus dissolved) concentrations. For some elements (Ba, Cd, Cu, Pb and Zn), the particulate matter from the surface microlayer was enriched with respect to those suspended materials taken from 0.2 m depth. This could reflect the atmospheric input of metal-rich aerosols. In anoxic deep waters, maximum contents of Zn (6400 µg g &lt;sup&gt;-1&lt;/sup&gt;), Cu (1330 µg...

During the Bremerhaven Workshop, the meiofaunal communities along 2 supposed North Sea pollution gradients, one at a drilling site off the Dutch coast and the other across the German Bight, were analysed by a variety of univariate and multivariate techniques and the changes on community structure related to a suite of measured environmental variables. At the drilling site the only evidence of change in community structure was a slight reduction in the abundance of nematodes in the deeper parts of the sediment (2 to 10 cm) close to the drilling site. Otherwise, there were no significant differences between sites using any other measure of community structure. It is concluded that sufficient time had elapsed since the cessation of drilling activity for a...

A simple semi flow-through culture technique for the controlled super-intensive production of &lt;i&gt;Artemia&lt;/i&gt; juveniles and adults
Provedor de dados: 27
Autores: Dhert, P.; Bombeo, R.; Lavens, P.; Sorgeloos, P.
A simple semi flow-through &lt;i&gt;Artemia&lt;/i&gt; culture unit is described for possible integration in marine fish and shellfish hatcheries as a source of a cheap nursery diet. The system does not require the use of feeding pumps and involves minimal care. Food preparation and addition to the feeding tank is reduced to one or two manipulations per day during the meta-nauplius stages (day 1-3) and the juvenile stages (day 4-14), respectively. Biomass productions are superior to those reported to those for stagnant culture systems and are comparable to those demonstrated for flow-through culture units. This simple rearing technique offers the possibility of producing brine shrimp populations with a uniform size. Furthermore, by varying the feeding...

Autores: Otten, P.; Injuk, J.; Rojas, C.; Van Grieken, R.
The North Sea is being under loaded in many ways, both by organic and anorganic pollutants. Transport over rivers is the most evident way. Direct emission along the coastline and dumping of toxic materials by vessels are another two causes of pollution. Exploitation of oil and gas platforms also lead to operational emission of certain noxious substances. “Last but not least” a part of the pollutants also reach the North Sea through the atmosphere.This article specifically concerns the latter facet of North Sea Pollution. Both gaseous and particular material is being emitted in the atmosphere through incineration and other polluting processes. After physical dispersion and chemical transformation, these pollutants can end up in the sea through deposit...

Autores: Van Malderen, H.; Rojas, C.; Van Grieken, R.
In order to investigate the importance of giant airborne particles, air sampling was carried out using an aircraft which flew at different altitudes over the Southern Bight of the North Sea. A set of 25 samples was collected with a steel rod on top of the airplane. Some 12,500 individual particles were analyzed using electron probe X-ray microanalysis. Principal factor analysis allowed identification of four sources of giant aerosol particles: aluminosilicates, combustion processes, industrial processes, and marine sources. Hierarchical and nonhierarchical cluster analysis enabled us to classify the analyzed particles. A clear distinction was found between flights for which the associated air masses were marine or continental. The experimentally found size...

A homage to homology: patterns of copepod evolution
Provedor de dados: 27
Autores: Boxshall, G.; Huys, R.
Lack of attention to determining the homology of character states is recognized as being responsible for the ever increasing numbers of phylogenetic schemes for the Crustacea that appear and disappear so rapidly. Detailed study of musculature. segmentation and setation of the limbs of all 10 orders of copepods revealed numerous phylogenetically informative characters. based on segmental fusion patterns and the presence of individually identified setation elements. Simple counts of limb segments (or of setae) were found to be virtually useless for constructing phylogenies in the copepods. This conclusion can probably be extended to other crustacean groups.

Laser microprobe mass analysis of individual North Sea aerosol particles
Provedor de dados: 27
Autores: Dierck, I.; Michaud, D.; Wouters, G.; Van Grieken, R.
Some 6000 individual aerosol particles in the 0.5-4-µm aerodynamic diameter range, collected from an aircraft at different heights above the North Sea, were analyzed using laser microprobe mass analysis (LAMMA). In this way, various well-separated particle types could be defined. Many of these particles appeared to occur as internal mixtures. Several definite trends in particle type abundances as a function of wind direction during sampling and of particle size could be observed. This helped in identifying source processes of the aerosol. Obtaining conclusive results as a function of sampling height, on the other hand was much less straightforward. This is not surprising, since most samples were collected under the inversion layer where extensive mixing is...

Autores: Antoine, N.; Jansegers, I.; Holsbeek, L.; Joiris, C.R.; Bouquegneau, J.-M.
In the North Sea, the contamination level of Cd in porpoises, Zn and Cu in seabirds and Hg in both appear to be very high. The other studied metals (Cr, Ti, Fe, Pb) concentrations are comparable to literature. Seabirds and porpoises are located at top of the food chains, however their use as bioindicators of the contamination level of the ecosystem they are feeding on remains debatable. Actually many differences appear in both the contamination level and the storage and detoxification mechanisms from a species to another.

State of the art of Asian seabass &lt;i&gt;Lates calcarifer&lt;/i&gt; larviculture
Provedor de dados: 27
Autores: Dhert, P.; Lavens, P.; Sorgeloos, P.
Innovative techniques opened new perspectives in the larviculture or the Asian seabass in the 1980s. Induced spawning maximized egg production while sperm preservation reduced the problem of male brood-stock supply. Studies of biometric characteristics of the fish larvae resulted in improved feeding strategies with live food. This in turn permitted a more rational use of expensive &lt;i&gt;Artemia&lt;/i&gt; nauplii. Nutritional enhancement of the highly unsaturated fatty acid (HUFA) composition of the life food resulted in significant improvement of survival and physiological condition of the larvae of the metamorphosis. A salinity stress test enabled the evaluation of the larvae's physiological status and estimation of their HUFA-requirements during the...

The meiobenthos of the North Sea: density, biomass trends and distribution of copepod communities
Provedor de dados: 27
Autores: Huys, R.; Herman, P.M.J.; Heip, C.H.R.; Soetaert, K.
During a synoptic survey carried out in April-May 1986, 171 localities were sampled in the North Sea as delimited by the Straits of Dover in the south and approximately by the 100m isobath in the north. Meiobenthos included Nematoda, Copepoda, Turbellaria, Gastrotricha, Polychaeta, Oligochaeta, Priapulida, Kinorhyncha, Ostracoda, Halacarida, Isopoda, Tanaidacea, Bryozoa, Cnidaria, Sipunculida, Echiurida, Nemertini and Tardigrada. Nematodes were the dominant group in virtually all stations, their densities ranging from 61 to 4167 individuals. 10cm&lt;sup&gt;-2&lt;/sup&gt;. Only in the Southern Bight, where nematode numbers were low, did harpacticoids sometimes represent the dominant meiobenthic taxon. There was a tendency for nematode (and total...

Atmospheric concentrations and size distributions of aircraft-sampled Cd, Cu, Pb and Zn over the Southern Bight of the North Sea
Provedor de dados: 27
Autores: Injuk, J.; Otten, Ph.; Laane, R.W.P.M.; Maenhaut, W.; Van Grieken, R.
In an effort to assess the atmospheric input of heavy metals to the Southern Bight of the North Sea, aircraft-based aerosol samplings in the lower troposphere were performed between September 1988 and October 1989. Total atmospheric particulate and size-differentiated concentrations of Cd, Cu, Pb and Zn were determined as a function of altitude, wind direction, air-mass history and season. The obtained data are compared with results of ship-based measurements carried out previously and with literature values of Cu, Pb and Zn, for the marine troposphere of the southern North Sea. The results point out the high variability of the concentrations with the meteorological conditions, as well as with time and location. The experimentally found particle size...

The use of artificial diets in the hatchery rearing of bivalve mollusks
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. Therefore, 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 results reported so far in the literature on the use of the various alternatives to on-site algal production. Furthermore, an overview is presented of the results obtained by the authors using manipulated yeasts as algal substitutes in feeding trials with juveniles of various commercially important bivalve species. Literature data and experimental findings were compared with experience "from the field" through an international inquiry among the operators...

Coprecipitation with aluminium hydroxide and x-ray fluorescence determination of trace metals in water
Provedor de dados: 27
Autores: Eltayeb, M.A.H.; Van Grieken, R.
Coprecipitation of trace elements on aluminium hydroxide was combined with energy-dispersive x-ray fluorescence for the analysis of environmental water. The parameters for the preconcentration method were studied. The optimum procedure involves addition of 1 mg of the carrier, at pH 7.3, to a 200-ml water sample. The pH was adjusted by addition of ammonia solution. Quantitative recoveries were obtained for Ti(IV), Cr(III_, As(V), Pb(II) and Th(IV). The precision was 4–6% and the detection limits were in the range 0.2–0.8 µg l-1.

Provedor de dados: 27
Autores: VandenSpiegel, D.; Ovaere, A.; Massin, C.
A study of the fauna associated with holothurians from Hansa Bay (Papua New Guinea) reveals a new symbiotic association between the holothuroid &lt;i&gt;Holothuria (Metriatyla) scabra&lt;/i&gt; and the crab &lt;i&gt;Hapalonotus reticulatus&lt;/i&gt;. All the collected holothurians were infested, but with only one crab per holothurian, always in the right respiratory tree near the cloaca. Because of its size, &lt;i&gt;H. reticulatus&lt;/i&gt; considerably expands the wall of the respiratory tree forming a membranaceous cyst. This association, therefore, appears to be parasitic. However, the crab does not feed upon host tissue but seems to filter its food from water passing through the respiratory tree of its host. The description of two males allows to...

IMPACTS OF LIBERALIZING THE JAPANESE PORK MARKET
Provedor de dados: 31
Autores: Wahl,   Thomas I.; Hayes,   Dermot J.; Johnson,   Stanley R.
The Japanese pork market is protected by a complex set of restrictions, including a variable levy and an import tariff. The combination of these policies distorts the quantity, price, and form of Japanese pork imports. An important issue relevant to the liberalization of the Japanese pork market is the accurate measurement of the price wedge between Japanese and world pork prices. The analysis indicates that the tariff equivalent of the price wedge over the 1986-88 period was 44%. If the tariff equivalent of the price wedge is reduced over a ten-year period, Japanese pork imports are projected to increase by over 39% initially and by over 215% compared to baseline projections by the year 2000. Producer welfare can be maintained by a deficiency payment...

Autores: Ruppel,   Fred J.; Fuller,   Stephen W.
Laboratory experimentation was used to assess the impacts of information disclosure in imperfect markets. A dual oligopoly market structure was designed with contract information disclosed to subjects under three treatments: no, partial, and full disclosure. Regression analysis revealed some increase in selling price with full information disclosure, but no discernable effects on negotiated prices with partial disclosure. Alternative specifications showed large traders earning significantly lower profits, and information on large traders significantly beneficial to both buyers and sellers. Probit analysis of information selection determinants revealed no significant economic content in trader requests for information under partial disclosure.

HETEROSKEDASTICITY IN CROP YIELD MODELS
Provedor de dados: 31
Autores: Yang,   Seung-Ryong; Koo,   Won W.; Wilson,   William W.
This study examines three alternative models of correcting for heteroskedasticity in wheat yield: the time trend variance, the GARCH, and an econometric model that includes the potential sources of heteroskedasticity. Nonnested test results suggest that modeling the sources of heteroskedasticity is the preferred procedure. Including potential sources of heteroskedasticity as explanatory variables removed the heteroskedasticity in the sample wheat yields. The results also suggest that the GARCH specification is a promising model of correcting for heteroskedasticity when the sources cannot be identified. The time trend variance model alone may misspecify the true variance structure.

Autores: Bush,   Eric J.
A national survey on swine health was conducted by the National Animal Health Monitoring System ( NAHMS ) from December 1989 through January 1991. The survey sample was designed in collaboration with the National Agricultural Statistics Service (NASS ) in order to provide inferences about the nation's hog population, 95 percent of which was represented. The program consisted of two parts: the first was a general farm management and policy questionnaire  that was completed by 1,661 producers. The second part of the program was a monitoring phase that took place over a three-month period for each of 712 participating producers. Per litter estimates for the national population showed an average of 9.9 piglets born alive and 8.4 weaned. Estimates attributed 57...

ALTERNATIVE MEASURES OF RISK IN COMMODITY SUPPLY MODELS: AN ANALYSIS OF SOW FARROWING DECISIONS IN THE UNITED STATES
Provedor de dados: 31
Autores: Holt,   Matthew T.; Moschini,   GianCarlo.
The role of price risk in sow farrowings is investigated by using bivariate ARCH-M and GARCH-M models and a nonparametric kernel estimator. To account for the relevant time horizon of irreversible supply decisions, predictions for mean price and conditional price variance are iterated forward. The empirical results vary markedly in terms of their implications for risk response in hog supply decisions, with the ARCH-M and GARCH-M models suggesting a small and negative risk effect. Estimates of the marginal risk premium also indicate moderate and variable departures from marginal cost pricing in sow farrowing supply decisions.

Famine in Ethiopia: Policy Implications of Coping Failure at National and Household Levels
Provedor de dados: 31
Autores: Webb,   Patrick; von Braun,   Joachim; Yohannes,   Yisehac.
This study argues that famines are preventable.  What was once a universal threat to human life is now primarily in Sub-Saharan Africa. Africa is likely to be the only continent to experience a continued high level of famine mortality during the 1990s, as well as an increase in absolute poverty. Therefore, the current challenge facing policymakers and research organizations such as IFPRI is to reduce the negative effects of famine in Africa and to lay the foundations for its longer- term eradication. This research by Patrick Webb, Joachim von Braum, and Yisehac Yohannes was designed to contribute to a better understanding of the root causes of famine and thereby to identify appropriate policies and projects for famine mitigation. As part of a larger IFPRI...

Institutional factors affecting irrigation performance in Pakistan: research and policy priorities
Provedor de dados: 31
Autores: Bandaragoda,   Don Jayatissa; Firdousi,   G.R.
The strong irrigation tradition has sustained the broad based community interest in irrigation. The result is a very complex institutional milieu in which a set of formally established irrigation rules and organizations exists side by side with an intricate set of social institutions. The two sets act like a dual system often in conflict with each other. The authors, while analyzing the present institutional barriers, have highlighted the importance of irrigation rules and procedures in the institutional framework.

Investment in Water Saving Technology on Horticultural Farms
Provedor de dados: 31
Autores: Mallawaarachchi,   Thilak; Hall,   Nigel H.; Phillips,   Brian.
A long run programming model for analysing investment behaviour on perennial crop farms is formulated and applied to citrus and wine grape producing farms in the Murumbidgee Irrigation Area. Prices and technological parameters are defined exogenously, while the optimal replanting pattern of the crops and the optimal mix of irrigation techniques are determined endogenously. The model is used to examine likely investment in water saving irrigation technology at different crop prices and input costs. The results indicate that such investment is a profitable option at current water charges, particularly for those farmers with access to off-farm employment However, the adoption decision will be highly sensitive to potential cost savings. Water-saving technology...

CERTIFICATION AND SUPPLY RESPONSE IN THE ORGANIC LETTUCE MARKET
Provedor de dados: 31
Autores: Lohr,   Luanne; Park,   Timothy A.
The impact of supply relationships and certification programs on the organic lettuce market is examined using an integrated partial adjustment and asymmetric supply response model. Costs associated with organic certification, production, and marketing have not restricted producers’' abilities to respond to price signals. Organic growers allocate output between certified and noncertified markets in response to changing price premiums. Estimates of short-run supply elasticities indicate that organic lettuce growers are more responsive to price changes than producers of nonorganic lettuce. Long-run elasticity has increased since 1988, a change that coincides with the market entry of larger producers.

Dairy Industry Policy
Provedor de dados: 31
Autores: Freebairn,   John W.
Current dairy industry policy facilitates discriminatory pricing of milk used for market milk, domestic manufactured products and for export products. A variant of the Parish model is used to estimate transfer and efficiency costs of these arrangements. Transfers from consumers to producers represent about a third of gross farm returns. Efficiency costs of too little consumption are small. Estimated costs of excess production are between $25 million and $65 million a year. The model suggests important changes to the way in which the Industry Commission calculates rates of assistance to the dairy industry.

PRODUCTIVITY GROWTH AND INPUT MIX CHANGES IN FOOD PROCESSING
Provedor de dados: 31
Autores: Adelaja,   Adesoji O.
To examine productivity growth in New Jersey's food-processing sector, this study conducts a joint analysis of total and partial factor productivity indexes.  Results indicate growing material intensity, declining labor and capital intensities, and relatively slow material productivity growth.  However, due to the high cost share of material inputs, material productivity growth contributed more to total factor productivity growth than did growth in the productivity of any other input.  In fact, almost half of the growth in overall productivity is attributed to material productivity growth.  Results also suggest that the 1973 decline in total factor productivity was characterized by greater decline in material productivity than in the productivities of...

AIDS and separability: a non sequitur
Provedor de dados: 31
Autores: Lee,   Jonq-Ying; Brown,   Mark G.; Seale,   James L., Jr.
The almost ideal demand system (AIDS) is commonly used to study demand for agricultural commodities and groups of commodities.  Increasingly, separability has been utilized in conjunction with the AIDS to estimate conditional demand systems as well as to improve upon precision of parameter estimates.  The paper shows that separability conditions are inconsistent with use of the AIDS and that tests of separability with the AIDS are problematic.

THE ADEQUACY OF TRUCKING SERVICE SUPPLIES FOR PRODUCE: TRENDS IN THE 1980S
Provedor de dados: 31
Autores: Beilock,   Richard P.; Dunton,   William; Kepler,   Paul.
Over 90 percent of interstate produce movements are by truck.  In recent years, concerns have been raised regarding the adequacy of motor carrier services.  Reasons for these concerns include the possibility of increased costs or service erosions resulting from relaxed economic regulations, an eroding road infrastructure, increasing congestion, more stringent safety regulations, demographic trends suggesting the onset of an increasingly severe driver shortage, and declines in rail capacity devoted to produce haulage.  In this study, trends in the adequacy of trucking services for trucking during the 1980s was examined employing data sets developed by the USDA regarding haulage from five growing areas to six metropolitan areas across the United States, and...

The article reviews recent developments in European Community (EC) agricultural markets and in the Common Agricultural Policy (CAP). In particular, the process of shaping CAP reform is extensively documented and commented on. It is seen as a means not so much to comply with national economic and external political requirements, but rather to continue agricultural protection for internal political reasons and to attempt to impose the Community's new position on the ongoing General Agreement on Tariffs and Trade (GA 11) negotiation of the Uruguay Round. With regard to the latter, attention is paid to the GATT questionnaire (Dunkel paper) and to the EC's response. Finally, new developments in the process of European integration (Single Market, EC enlargement,...

AN EVALUATION OF RISK MANAGEMENT STRATEGIES FOR DAIRY FARMS
Provedor de dados: 31
Autores: Bosch,   Darrell J.; Johnson,   Christian J.
Variability in feed prices and crop yields are important sources of risk to dairy farmers. A simulation model of a representative dairy farm was used to evaluate crop insurance and hedging as risk management strategies. These strategies lowered expected net returns but also reduced risk. The preferred set of strategies at lower levels of risk aversion included hedging and crop insurance, although a base scenario in which no risk management strategies were employed was also efficient. The preferred strategy at higher levels of risk aversion was a combination of crop insurance and hedging.

The Changing Role of the Korean Food Store in New York City
Provedor de dados: 31
Autores: McLaughlin,   Edward W.; Russo,   David M.
New York City boasts one of the world's largest urban areas and metropolitan populations. These conditions present enormous challenges to the distribution of food products for New York City residents. The distribution system that has emerged in response to these challenges is unique: specialty store food sales, in particular, are more important in New York than in any other state. Yet very few studies have attempted to examine or document the system's uniqueness. This paper reports on a study conducted of one especially distinctive aspect of New York's food distribution landscape, the Korean Grocery Store. Ninety Korean food store owners were personally interviewed, by trained interviewers fluent in Korean, regarding their perceptions, standard retail...

Autores: Donaldson,   David.
This article investigates the properties, good and bad, of social evaluations based on four money measures of well-being or changes in well-being: compensating variations, money metrics, extended money metrics, and welfare ratios. Consistency of social rankings (transitivity, asymmetry of preference), the possibility of incorporating inequality aversions, independence of the choice of reference prices, and the ethics implicit in the evaluations are considered. In addition, these procedures are contrasted with utility aggregation using equivalence scales.

PROTEST BIDDERS IN CONTINGENT VALUATION
Provedor de dados: 31
Autores: Halstead,   John M.; Luloff,   A.E.; Stevens,   Thomas H.
Protest bids are often excluded during analysis of contingent valuation method data.  It is suggested that this procedure might introduce significant bias.  Protest bids are often registered by respondents who may actually place a higher- or lower-than-average value on the commodity in question but refuse to pay on the basis of ethical or other reasons.  Exclusion of protest bids may therefore bias willingness to pay (WTP) results, but the direction of bias is indeterminate a priori.

For several years, universities in the U.S. have been struggling with defining and refining undergraduate and graduate agribusiness education programs. With the release of the recommendations of the National Agribusiness Education Commission, the search for the key ingredients of a Masters-level program has intensified. Mississippi State University has been among those universities attempting to define the parameters of a "cutting edge" agribusiness program. Faculty interest within the College of Business and Industry and the Agricultural Economics Department to develop a joint program has precipitated intensive efforts to achieve this goal.

ENVIRONMENTAL EFFECTS OF TRADE IN THE AGRICULTURAL SECTOR: A CASE STUDY
Provedor de dados: 31
Autores: Runge,   C. Ford.
Agriculture has been at the center of conflicts over world trade from the beginning in 1986 of the eighth, Uruguay Round, of multilateral trade negotiations.  Yet it is only in the final phases of the Round that linkages from trade to the environment have come to the fore.  In this paper, the specific linkages from trade to the environment in the agricultural sector are developed.  The impacts of trade flows and policies on environmental quality in agriculture have features which make them unusually difficult to resolve.  In many respects, the same domestic agricultural policies at the root of trade distortions also encourage environmental damages.  Hence, reforming these domestic and trade policies would be a partial, though not a complete, step in the...

ESTIMATION OF FIRM-VARYING, INPUT-SPECIFIC EFFICIENCIES IN DAIRY PRODUCTION
Provedor de dados: 31
Autores: Lass,   Daniel A.; Gempesaw,   Conrado M., II.
Firm-varying production technologies were estimated using random coefficients regression methods for a sample of Massachusetts dairy farms.  Results were compared to OLS Cobb-Douglas production function estimates.  The random coefficients regression model was found to virtually eliminate conventionally measured firm technical inefficiencies by estimating individual firm technologies and ascribing remaining inefficiencies to specific inputs.  Input-specific measures of firm inefficiencies showed hired labor, land, and machinery inputs to be used in excess of efficient levels.  Livestock supplies were underutilized by all farms.  Efficiencies of feed, crop materials, fuels, and utilities varied, although estimated means were closer to optimal levels.

An understanding of the structure and characteristics of property rights in land clarifies a number of issues in the area of economic efficiency and administrative practicality, and focusses on areas where appropriate solutions to externalities may be difficult to achieve.

THE IMPACTS OF QUALITY ON CASH FED CATTLE PRICES
Provedor de dados: 31
Autores: Jones,   Rodney D.; Schroeder,   Ted C.; Mintert,   James R.; Brazle,   Frank.
Quality factors affecting fed cattle prices were examined during a six-month period in southwestern Kansas. Transaction prices were significantly affected by the percentage of cattle expected to grade choice times the choice-to-select carcass price spread, finish uniformity, average weight, dressing percentage, breed, number of cattle purchased by a single packer on a given day, the packer, the feedyard, the day-of-the-week the cattle were sold, and the number of bids received. Asking prices were significantly affected by many of the same factors. Asking and transaction prices reflected approximately 25 percent of the packer value differentials for expected carcass quality grades.

Many states have farm record associations which collect individual farm data. This data are used for research, extension, and teaching purposes. However, since membership in the associations is voluntary, the question arises whether the members are representative of the population of all farmers in that area. This study compares farm record data collected through the Southeastern and Southwestern Minnesota Farm Business Management Associations (FBMA) and data obtained through the USDA's Farm Costs and Returns Survey (FCRS). Both data sets were for 1987. By design, the FCRS survey is not subject to the self-selection bias that may occur in the FBMA data. The objectives of this study are to: (1) determine which farm characteristics are statistically the same...

Provedor de dados: 31
Autores: Fernandez-Cornejo,   Jorge.
Short- and long-run Hicksian and Marshallian elasticities are estimated, along with Morishima elasticities of substitution, using a restricted profit function and a series of decomposition equations.  Convexity in prices and concavity in quasi-fixed factors of the restricted profit function are simultaneously imposed using Bayesian techniques.  The empirical model is disaggregated in the input side, utilizes a Fuss-quadratic flexible functional form, incorporates the impact of agricultural policies, and introduces a new weather index.  The methodology is applied to Illinois's agriculture, and implications for agriculture in the Corn Belt and the Northeast are briefly discussed.

THE ECONOMIC THRESHOLD FOR GRASSHOPPER CONTROL ON PUBLIC RANGELANDS
Provedor de dados: 31
Autores: Davis,   Robert M.; Skold,   Melvin D.; Berry,   James S.; Kemp,   William P.
The U.S. Department of Agriculture's Animal and Plant Health Inspection Service (APHIS) is responsible for controlling grasshopper populations on public rangelands. Under current guidelines, control of grasshoppers on rangeland should occur if grasshopper densities are at least eight per square yard. This article evaluates the concept of an economic threshold relative to the value of forage saved from destruction during a grasshopper outbreak. It is shown that financial justification for treating grasshopper outbreaks depends upon grasshopper density, rangeland productivity, climate factors, livestock cost and return relationships, and the efficacy of treatment options.

DETERMINANTS OF CATTLE FINISHING PROFITABILITY
Provedor de dados: 31
Autores: Langemeier,   Michael R.; Schroeder,   Ted C.; Mintert,   James R.
Data from a western Kansas feedlot were analyzed to estimate the quantitative impacts of price and performance variables on profits per head from finishing cattle.  Sale prices, feeder prices, and corn prices had the most impact on profit variability over time.  Differences in sale prices, feeder prices, and feed conversions were important in explaining the difference in steer and heifer profits over time.  Results suggest that breakeven prices should be calculated for a range of fed cattle, feeder, and corn prices, and that these three variables need to be stochastic in representative farm modeling efforts.

THE POTENTIAL FOR INTRASEASONAL MARKET FLOW MANAGEMENT OF SOUTHEASTERN SWEET POTATOES
Provedor de dados: 31
Autores: Epperson,   James E.; Huang,   Wan-Tran.
The potential for a marketing order involving management of intraseasonal shipments of southeastern sweet potatoes was examined through a comparison of prices, shipments, and producers' surplus measures for the dynamic competitive equilibria case and the actual market case. The results of the study suggest that supply controls would not be beneficial, at least in the usual sense. The proper strategy would appear to be to increase rather than limit shipments of quality sweet potatoes in all seasons of the year.

A Noncooperative Model of Collective Decision Making: A Multilateral Bargaining Approach
Provedor de dados: 31
Autores: Rausser,   Gordon C.; Simon,   Leo K.
This paper extends the Stahl-Rubinstein model of bilateral bargaining to incorporate many players and multidimensional issue spaces. A central feature of our framework is that in each round of negotiations, a proposer is selected randomly. Our bargaining model consists of a sequence of finite-horizon games, in which the horizon increases without bound. A solution to our model is a limit of equilibrium outcomes for the finite horizon games. A necessary condition for existence of a deterministic solution is that the limit outcome belongs to the core of the underlying bargaining problem. Solutions, if they exist, are generically unique. Two sets of sufficiency conditions for existence are presented. The paper concludes with examples and applications. In...

Factors Affecting Japanese Investment in the Australian Beef Industry
Provedor de dados: 31
Autores: Morison,   Julian B.; Officer,   Linda J.
This paper begins with details on the current level of Japanese investment in the Australian beef industry. The reasons for direct investment by Japanese firms in the Australian beef industry are investigated, as is the nature and extent of integration by these firms in the Japanese beef production and marketing chain. The results are shown to be consistent with foreign direct investment theory. Specifically, the desire to provide quality assurance through ownership of upstream production facilities and the potential to exploit a domestic marketing and distribution advantage provide the principal motivations for beef industry foreign direct investment by Japanese firms.

As small finns grow from employing just a few people to employing 10 or more, there is an increasing need for more fonnalized human resource management practices. The purpose of this study was to determine to what extent managers of florist crop production finns used formalized human resource management practices in their businesses. Managers of 104 florist crop production firms in New York, Ohio, Pennsylvania, and Michigan participated in a telephone survey designed to gather information on specific personnel management practices. The study revealed that while some finns are using fonnalized personnel management practices, the majority are not. Those who use formalized personnel management practices tend to be, but are not exclusively, larger firms....

A multiproduct variable cost function was used to compare the efficiency of Midwestern cooperative and investor-oriented grain and farm supply firms. Results suggest that cooperatives are no less efficient in a variable cost sense than their investor-oriented counterparts. Concerning fixed input-variable cost elasticities, investor-oriented firms may be more effective in their use of plant and equipment, but cooperatives make more efficient use of other fixed inputs.

ADOPTION OF DOUBLE-CROPPING SOYBEANS AND WHEAT
Provedor de dados: 31
Autores: Shapiro,   Barry Ira; Brorsen,   B. Wade; Doster,   D. Howard.
Double-cropping of soybeans and wheat is often promoted by extension personnel.  This paper seeks to explain how the decision to adopt double-cropping is made, using a Tobit regression model.  Tobit makes use of more of the information in the data set than do logit or probit and explains not only the decision to double-crop but also the rate of adoption.  The paper considers factors such as profit and risk perceptions and risk which have not been included in the past models used to explain adoption of technology.  The results show that risk perception is important.  Contrary to the findings of some other adoption studies, this decision is not influenced by human capital factors.  The farmers who double-crop are more highly leveraged and appear to do so...

FARM OPERATING RISK AND CASH RENT DETERMINATION
Provedor de dados: 31
Autores: Turvey,   Calum G.; Baker,   Timothy G.; Weersink,   Alfons.
This article examines farm operating risks and cash-rent determination through the use of the efficient set mathematics. The efficient set mathematics proves to be a pragmatic approach to characterizing operating risks, and the relationships between operating risks and cash-rent determination. Various separation theorems are used to postulate the relationship between operating risk and cash rents. Preliminary evidence appears to support the theoretical conclusion that opperating risk and cash-rent determination are related.

FACTORS INFLUENCING PRODUCER SUPPORT FOR A STATE MANDATORY SEED LAW: AN EMPIRICAL ANALYSIS

Autores: Makus,   Larry D.; Guenthner,   Joseph F.; Lin,   Biing-Hwan.
A probit model identifies characteristics influencing Idaho potato producer support or opposition to a state mandatory certified seed law. Economic self interest appears to be the most important influencer. Current users of certified seed and growers of certified seed are strong supporters. However, producer attitudes about the impact of seed-borne diseases and effectiveness of certified seed as a control mechanism also are important. Respondent characteristics (gross farm income, potato acreage, and geographic region of the state) seem to be less important influencers.

IN DEFENSE OF FENCE TO FENCE: CAN THE BACKWARD BENDING SUPPLY CURVE EXIST?
Provedor de dados: 31
Autores: Just,   Richard E.; Zilberman,   David.
Politicians dealing with the “"farm problem”" sometimes lament that output increases when prices go up and when prices go down. This article presents three possible theoretical explanations. In the first, farmers deplete soil (over-farm) when prices are low and imperfect capital markets prevent borrowing. In the second, farmers in financial stress (low prices) allocate more family labor to farming to meet debt-repayment constraints. In the third, wealth held in farmland tends to decline as prices decline. With decreasing absolute risk aversion, this increases risk aversion which, in extreme cases, causes negative supply response.

ASSESSING THE RESEARCH FRAMEWORK AND INSTITUTIONAL CONTEXT FOR RURAL DEVELOPMENT POLICY
Provedor de dados: 31
Autores: McGranahan,   David A.
The economic context for rural development has changed markedly since the 1970s. While natural resource industries have continued to decline in importance as rural employers, the internationalization of markets, reorganization of industries, new production technologies, and the rapid development of new information technologies have eroded the competitive position of many rural areas with respect to other industries. In the South, as well as in the rest of the country, the critical rural issue for the 1990s is whether rural areas will be able to find niches to replace those they lost in the 1980s. Thus far, the new economy has been primarily an urban economy, and most rural areas have been left out. This has serious implications for rural development policy.

FIELD TRIALS AS AN EXTENSION TECHNIQUE: THE CASE OF SWAZILAND
Provedor de dados: 31
Autores: Abler,   David G.; Rauniyar,   Ganesh P.; Goode,   Frank M.
One potentially serious problem in evaluating the effectiveness of extension programs is that participants are not picked at random.  Self-selection can be a problem, and it can be compounded if extension officials concentrate on the most progressive farms.  This study explores the relationships between adoption of maize high-yielding varieties (HYVs) and participation in field trials intended to foster HYV usage, drawing on data from Swaziland.  Results indicate that it is impossible to say if field trials had any effect on adoption.  Participating farms used more HYVs, but this could have been due to self-selection or the government's selection process.

The past decade has been a period of turmoil for the manufacturing sector in both the U.

The purpose of this study was to increase our understanding of the firms that comprise the manufacturing sector in North Dakota and in the Provinces of Manitoba and Saskatchewan. Data came from a survey of firms conducted in 1991. A total of 333 firms (214 from North Dakota, 61 from Manitoba, and 58 from Saskatchewan) returned useable surveys. Durable goods manufacturers dominated the sample, accounting for 65 percent in Manitoba, 66 percent in North Dakota, and 78 percent in Saskatchewan. Many of the participating firms were relatively new; about 59...

WHY DO FARMERS FORWARD CONTRACT IN FACTOR MARKETS?
Provedor de dados: 31
Autores: Haydu,   John J.; Myers,   Robert J.; Thompson,   Stanley R.
This study investigated farmers' incentives to forward purchase inputs.  A model of farmer decision making was used to derive an optimal forward contracting rule. Explicit in the model was the tradeoff between the quantity of input to be purchased in advance, and the remaining portion to be purchased later on the spot market.  Results indicated that the primary reasons farmers contract inputs are to reduce risk and to speculate on favorable price moves.  A numerical example of fertilizer used in corn production indicated that the size of the price discount was the dominant factor in forward contracting decisions.

SUPPLY MANAGEMENT PROGRAM ALTERNATIVES FOR THE TART CHERRY INDUSTRY
Provedor de dados: 31
Autores: Hinman,   Donald L.; Ricks,   Donald J.
Two interrelated supply problems facing the tart cherry industry are long-run cyclical patterns in industry productive capacity and substantial annual supply fluctuations. Following the termination of a federal marketing order in effect for 14 years, the industry has considered a number of other supply management options. None have been adopted on a broad industry basis. Recent proposals involved formation of a multi-state supply management cooperative and use of a state marketing order in Michigan. Annual supply management alternatives include reserve pool, market allocation, and non-harvest. An orchard removal incentive program was proposed to reduce industry productive capacity.

Pricing and Marketing Practices for North Dakota Durum and HRS Wheat: 1991 Crop Year
Provedor de dados: 31
Autores: Scherping,   Daniel J.; Wilson,   William W.
Buyers of grain use premiums and discounts to convey to suppliers the value of quality characteristics. Premiums and discounts are determined by supply and demand for those quality characteristics. This report, the eighth in a series, contains the results of a 1991 survey of pricing and marketing practices used by North Dakota country elevators for durum and hard red spring (HRS) wheat. Results for HRS wheat show that the protein level increased to the highs of 1988 and 1989 and that the premium for 16 percent protein and the discount for 12 percent protein decreased from the previous year. Discounts continued the downward trend of recent years.

DYNAMICS AND PRICE VOLATILITY IN FARM-RETAIL LIVESTOCK PRICE RELATIONSHIPS
Provedor de dados: 31
Autores: Kesavan,   T.; Aradhyula,   Satheesh V.; Johnson,   Stanley R.
This study uses an error correction model (ECM) to investigate dynamics in farm-retail price relationships. The ECM is a more general method of incorporating dynamics and the long-run, steady-state relationships between farm and retail prices than has been used to data. Monthly data for beef and pork are used to test the time-series properties for the ECM specification. The model is extended to study price volatility through the generalized autoregressive conditional heteroskedasticity (GARCH) process. Accommodation of the GARCH process provides a useful way of analyzing both mean and variance effects of policy or market structure changes.

Land Salinisation, Waterlogging and the Agricultural Benefits of a Surface Drainage Scheme in Benerembah Irrigation District
Provedor de dados: 31
Autores: Jones,   Randall E.; Marshall,   Graham R.
Soil salinisation and waterlogging are significant problems in the Irrigation Areas and Districts of southern New South Wales. Various actions can be taken at either a regional or farm level to alleviate these problems. District surface drainage, sub-surface drainage, pumping from deep aquifers and changes to water pricing policies are regional options, while possible on-farm options include laser controlled landforming, pumping groundwater from shallow aquifers, recycling drainage water, changes to crops and rotations and the adoption of improved irrigation systems. The purpose of this study was to analyse the agricultural benefits of a surface drainage scheme proposed for an Irrigation District in the Murrumbidgee Valley. The objective of the analysis...

Prior Information, General Information, and Specific Information in the Contingent Valuation of Environmental Risks: The Case of Nitrates in Groundwater
Provedor de dados: 31
Autores: Poe,   Gregory L.; Bishop,   Richard C.
Information, or lack thereof, is an important input in value formation and the distribution of contingent values. Although most conceptualizations of the contingent valuation process stress that information provision should be 'adequate,' very little empirical research has been devoted to assessing the effects of different information flows on contingent values and to establishing a standard of information adequacy for contingent valuation studies. The need for such research is particularly cogent for valuing the benefits of reducing environmental risks, a non-market good which is increasingly being valued with the contingent valuation method. Using nitrates in groundwater as a case study, this paper evaluates and compares health risk perceptions and the...

FARM-LEVEL RESPONSE TO AGRICULTURAL EFFLUENT CONTROL STRATEGIES: THE CASE OF THE WILLAMETTE VALLEY
Provedor de dados: 31
Autores: Taylor,   Michael L.; Adams,   Richard M.; Miller,   Stanley F.
This article examines economic incentives and other mechanisms to offset non-point source pollution from agriculture. A biophysical simulator to estimate technical relationships is linked to linear programming models for representative farms in the Willamette Valley of Oregon. The models are then optimized for profit maximization under alternative non-point pollution control policies. The results indicate that site-specific resource conditions and production possibilities greatly influence policy effectiveness and the cost of achieving pollution abatement. Nevertheless, some abatement is possible on all farms for relatively little cost.

A Note on Price Levelling and Price Averaging in Sydney Retail Vegetable Price Spreads
Provedor de dados: 31
Autores: Griffith,   Garry R.; Jamandre,   W.E.; Piggott,   Roley R.
For tomatoes, potatoes, carrots and onions in the Sydney market, the degree of variability of the retail price is substantially lower than the degree of variability of the wholesale price. The objective here is to investigate whether fresh vegetable retailers in the Sydney market practice price levelling and price averaging. 2SLS and 3SLS procedures were used to estimate a system of price spread equations for the four vegetables using quarterly data from 1980 to 1990. In the preferred 3SLS estimates price levelling was confirmed for potatoes and carrots. Price levelling was not evident in the tomatoes and onions equations, with price transmission influenced more by markup pricing policies for these vegetables. No evidence of price-averaging behaviour was...

QUASI-EXPERIMENTAL DESIGNS FOR MEASURING IMPACTS OF DEVELOPMENTAL HIGHWAYS IN RURAL AREAS
Provedor de dados: 31
Autores: Broder,   Josef M.; Taylor,   Teresa D.; McNamara,   Kevin T.
Quasi-experimental techniques were developed to provide decision-making tools for documenting the impacts of developmental highways in rural areas.  Regression discontinuity analysis (RDA) with limited observations was used to compare economic changes in highway counties to those in adjacent and non-adjacent control counties.  The RDA models found statistically significant changes in population, per capita income, and taxable sales related to highway development.  The study found that some counties benefited from developmental highways, some were unchanged, while some experienced economic decline.  RDA models with adjacent controls had better explanatory powers while those with non-adjacent controls were more sensitive to highway-related changes in...

CONSUMER DEMAND ANALYSIS ACCORDING TO GARP
Provedor de dados: 31
Autores: Alston,   Julian M.; Chalfant,   James A.
The nonparametric approach to consumer-demand analysis-based on revealed-preference axioms-is reviewed.  Particular attention is paid to questions of size and power of tests for consistency of data with the existence of a stable, well-behaved utility function that could have generated the data.  An application to Australian meat demand is used to show how these notions can be quantified and how prior information about elasticities, following Sakong and Hayes, may be used to increase the power of the approach.

MATHEMATICAL PROGRAMMING FOR RESOURCE POLICY APPRAISAL UNDER MULTIPLE OBJECTIVES
Provedor de dados: 31
Autores: McCarl,   Bruce A.
Mathematical programming is one technique that can be used for resource policy appraisal.  Multiple objectives are usually involved in resource policy considerations.  This paper discusses issues regarding the use of mathematical programming techniques for the multiobjective resource policy arena.  Theoretical models are introduced with a separation called for between producer response models and policy maker models due to a disparity of objectives.  The paper draws on the literature citing cases where producer level models have been utilized to simulate the policy outcome implications of alternative policies.

Branded Product Marketing Strategies in the Cottage Cheese Market: Cooperative versus Proprietary Firms
Provedor de dados: 31
Autores: Haller,   Lawrence E.
This paper examines structural and strategic factors affecting price determination in the branded cottage cheese industry.  Special emphasis is placed on the presence and conduct of cottage cheese brands marketed by dairy cooperatives.  The data examined in this study cover cottage cheese sales in 47 markets for the fourth quarter of 1988.  We find evidence supporting the premise that market power is being exercise in the cottage cheese market.  One of the strongest influences of the price of cottage cheese is the extent of market penetration of the brand.  Brands' prices rise with an increase in the price of private label cottage cheese.  We also find strong evidence that cooperatives are not exercising market power.  Cooperatives charge a lower price...

RISK AND RETURN IN AGRICULTURE: EVIDENCE FROM AN EXPLICIT-FACTOR ARBITRAGE PRICING MODEL
Provedor de dados: 31
Autores: Bjornson,   Bruce; Innes,   Robert.
This article develops and estimates an explicit-factor Arbitrage Pricing Theory (APT) model in an endeavor to uncover (a) the systematic risk properties of returns to agricultural assets, (b) the relationship between agricultural returns and returns on comparable-risk nonagricultural assets, and (c) the possible relevance of agriculture-related risks in general capital markets. The article concludes that: (a) farmer-held assets have exhibited significant systematic/ factor risk over the 1963-82 estimation interval, but U.S. farmland has not exhibited such risk; (b) a grain-price index has been a priced factor in general capital markets; and (c) average returns on farmer-held assets have been significantly lower; and average returns on U.S. farmland...

IMPACTS OF GROWTH STIMULANTS IN THE DOMESTIC LIVESTOCK SECTOR
Provedor de dados: 31
Autores: Peterson,   Everett B.; Preckel,   Paul V.; Hertel,   Thomas W.; McGuirk,   Anya M.
Many individuals are predicting a "second green revolution" in agriculture from the introduction of growth stimulants into the livestock industries. An economy-wide approach is used to determine the affects on prices and quantities of introducing growth stimulants in the domestic dairy and pork industries. In general, the impacts are found to be much smaller than previous research focused at the sectoral level has suggested. Increases in the amount of lean meat per hog, which reduces processor demand, may actually lead to a reduction in pork production at the farm-level.

Economic Feasibility of an Air Cargo Handling Facility at Fargo, North Dakota
Provedor de dados: 31
Autores: Golz,   Theresa K.; Golz,   Joel T.; Koo,   Won W.
Exports to Taiwan in 1990 via air freight were approximately $2.9 billion, and imports via air freight to the united States were $3.1 billion. Total U.S. exports/imports to/from Taiwan in 1990 were $11.5 billion and $22.7 billion, respectively. China Airlines operates three air cargo hubs in the united States: New York, Los Angeles, and Dallas. The real per capita Gross National Product (GNP) in Taiwan for 1989 was $7,512, up from $3,297 in 1985. This implies that the Taiwanese economy is one of the fastest growing economies in Asia. Trade volume between the united States and Taiwan has increased substantially over the last 10 years and is predicted to grow in the future.

From Ecology to Economics: The Case Against CO2 Fertilization
Provedor de dados: 31
Autores: Erickson,   Jon D.
The effects of increasing concentrations of atmospheric carbon dioxide (C02) on agricultural yields are analyzed. It is argued that any positive effects on yields from C02 fertilization, demonstrated in controlled experiments, would be weak in farm conditions given water and nutrient limits. Furthermore, possible benefits would be more than offset by predicted consequences of climate change, ozone depletion, and additional gases created from fossil fuel combustion. The impact of including C02 fertilization on crop yield and economic welfare predictions is evaluated. The policy distorting potential of fragile claims is stressed

Disparity between Hunters' Willingness to Pay and Willingness to Accept Compensation: An Empirical Example
Provedor de dados: 31
Autores: Stratton,   Gary R.; Smathers,   Webb M., Jr.; Gooding,   Robert.
Willingness-to-pay (WTP) and willingness-to-accept (WTA) compensation models were estimated for hunters using a portion of the Clarks Hill wildlife Management Area during 1989-1990. Hunters' WTA values ranged from 2.8 to 8 times more than WTP. Income and wealth effects as well as property rights clearly contributed to this disparity in WTP and WTA compensation for the right to hunt in the wildlife Management Area. Responding hunters spent an average of $750 for hunting related activities or about five percent of their disposable income.

Cooperative Principles and Equity Financing: A Critical Discussion
Provedor de dados: 31
Autores: Royer,   Jeffrey S.
This paper examines the role of the “principles of cooperation” in shaping the methods used by farmer cooperative associations for the provision of equity capital by members. Cooperative principles and financing practices based on them are evaluated in the context of some common issues and conflicts among patrons. The characteristics of a cooperative are compared with those of a patron-owned corporation, and two case studies in which patrons chose to organize businesses as patron-owned corporations are discussed. The paper concludes by making recommendations for patron-owned businesses operating within the cooperative framework.

AGRICULTURAL ADAPTATION TO URBANIZATION: FARM TYPES IN NORTHEAST METROPOLITAN AREAS
Provedor de dados: 31
Autores: Heimlich,   Ralph E.; Barnard,   Charles H.
Metropolitan agriculture is not homogeneous.  This paper delves beneath metropolitan county averages using data on individual farms in the Northeast classified into three statistically distinct types.  A small group of adaptive farms profit from intensive production on smaller acreage to accommodate themselves to the urban environment.  Traditional farms have increased costs and pressures on their more extensive operations without compensating increases in revenue from better-adapted enterprises.  A large group of recreational farms subsidize small-farm activities from nonfarm income.  Operating characteristics of each farm type are presented and their importance to metropolitan agriculture is assessed.  Implications for preserving farming and farmland in...

An economic analysis was conducted of the Maissade Integrated Watershed Management Project in Haiti.  This project, implemented by the Save the Children Federation, differs from conventional watershed management projects by investing heavily in the development of peasant organizations in order to gain voluntary and sustained adoption of soil conservation, forestry and community development innovations.  Conventional projects have relied on monetary and commodity incentives in order to encourage technique adoption, and are widely viewed to have failed to achieve sustained watershed management. The goal of the economic analysis was to determine if a project representative of the new, participatory approach was economically efficient from donor and peasant...

Risk and the Farm Firm: A Corporate Finance View
Provedor de dados: 31
Autores: Johnson,   R.W.M.
Recent applications of risk analysis in corporate finance to farm firm decision making are reviewed in this paper. The inclusion of risk parameters modifies some of the traditional agricultural economics views on investment, financing and the portfolio choice problem. A clearer view emerges of farm investment behaviour. Further topics for research are identified. In the author's view, the corporate finance analysis provides a more coherent set of paradigms that explain actual farm investment and financing decision making m a more satisfactory way than previously available.

The general objective of this study was to evaluate the economics of alternative technologies, systems and methods of fabricating and marketing retail packaged beef. A national beef distribution model (VAL-ADD) was developed and used to compare the economics of various case-ready systems with the conventional system of fabricating beef in the back room of the retail store. The VAL-ADD model identifies beef price premiums and/or discounts by packaging system for each of 30 regional distribution routes within the contiguous United States. In addition it estimates the competitive advantage of regions in central packaging. The Central and Southern Plains areas have a competitive advantage in producing prepackaged retail beef and retailers with high labor costs...

LIVESTOCK FUTURES MARKETS AND RATIONAL PRICE FORMATION: EVIDENCE FOR LIVE CATTLE AND LIVE HOGS
Provedor de dados: 31
Autores: Koontz,   Stephen R.; Hudson,   Michael A.; Hughes,   Matthew W.
The efficiency of livestock futures markets continues to receive attention, particularly with regard to their forward pricing or forecasting ability.  The purpose of this paper is to present a more general theory that encompasses the forward pricing concept.  It is argued that futures contract prices for competitively produced nonstorable commodities, such as live cattle and live hogs, follow a rational formation process.  Futures contract prices reflect expected market conditions when contracts are sufficiently close to the delivery month that the supply of the underlying commodity cannot be changed.  However, prior to the period when future supplies are relatively fixed, futures contract prices should adjust to reflect the competitive equilibrium, where...

Autores: Jordan,   Jeffrey L.; Elnagheeb,   Abdelmoneim H.
The 1990 Farm Bill contains several measures concerning soil erosion caused by U.S. farmers.  Data from a nationwide survey of people concerning their attitudes toward agriculture were used to examine the structure of respondents' preferences for government support-policies to combat soil erosion.  Estimates of the influence of socio-economic and demographic variables on policy preferences were computed using a multiple-indicator model.  Results show more support for the regulation of soil erosion, including laws and fines, than for government financial support.

Autores: Cummings,   Laurie Angela.
This paper uses data from a survey of 710 Michigan farm families who actively sought assistance in transitioning from farm to off-farm employment during the period of 1986 to 1988. Respondents were divided into three transition groups depending on the degree to which they depend off-farm income. The three groups represent farm households that have completely transitioned out of agriculture, largely transitioned out, and those who are still primarily dependent on agriculture.  Results reveal that 33 percent have made a complete transition, 48 percent are part-time farming, and 19 percent are full-time farming. Those practicing part-time farming were found to have higher incomes than those who completely quit farming and those full-time farming.  Education,...

A Dynamic Optimisation of Summer/Autumn Feeding Strategies for Wool Production in the Mediterranean Environment of Western Australia
Provedor de dados: 31
Autores: Wang,   K.M.; Curtis,   K.M.S.
To counteract declining quantity and poor quality of paddock feed over summer/autumn, farmers in Western Australia must decide how much of which supplement to provide to grazing sheep to optimise the use of supplements. The solution is complicated by the interaction of biological and economic factors and the intertemporal nature of the problem. A dynamic programming approach was used to determine optimal feeding strategies for different starting conditions. Lupin seed was preferred to oats for weaners when paddock feed was abundant, while oats was preferred for weaners and adults when paddock feed was scarce. The optimal feeding rate usually starts low and then gradually increases to higher rates as the autumn break approaches.

Agricultural Policy Developments in the United States: 1991-93
Provedor de dados: 31
Autores: Runge,   C. Ford; Vande Kamp,   Philip R.
Comprehensive federal agricultural legislation occurs in the United States (US) on a five-year schedule. While year-to-year changes in agricultural policy do occur, the period 1991-93 has been less eventful than many previous ones. What changes have occurred to affect the course of the agricultural sector and agricultural policy are largely external to the farm bill and farm legislation. These include the North American Free Trade Agreement (NAFTA), tentatively agreed in August 1992; the on-going negotiations in the General Agreement on Tariffs and Trade (GATT) and the related dispute with the European Community (EC) over oilseed subsidies; the emergence in connection with both NAFTA and GATT of the "trade and environment" issue; a continuing dispute over...

SHRIMP MARICULTURE DEVELOPMENT IN ECUADOR: SOME RESOURCE POLICY ISSUES
Provedor de dados: 31
Autores: Southgate,   Douglas.
During the past 15 years, Ecuador has become the Western Hemisphere's leading producer and exporter of shrimp.  Growth has come about largely through mariculture development.  About 8,000 metric tons (MT) of shrimp have been captured off the Ecuadorian coast each year since the late 1970s.  Meanwhile, pond output has increased several-fold, from less than 5,000 MT in 1979 to over 100,000 MT 12 years later (Table 1). Mariculture has expanded largely at the expense of renewable natural resources.  Mangrove swamps, characterized by extremely high biological productivity and, therefore, a critical element of coastal ecosystems, have been displaced.  In addition, shrimp postlarvae (PL) collection has at times been excessive and wastewater emissions from some...

LANDHOLDER COOPERATION FOR SUSTAINABLE UPLAND WATERSHED MANAGEMENT: A THEORETICAL REVIEW OF THE PROBLEMS AND PROSPECTS
Provedor de dados: 31
Autores: White,   Thomas A.
Despite national legislation and substantial donor investments, watershed degradation continues to threaten the sustained economic development and social welfare of millions of citizens in the developing world.  Past efforts have largely concentrated on the physical rather than institutional aspects of watersheds, and have often relied on external incentives to coerce or persuade individuals to adopt conservation practices.  In contrast to this conventional "physical" perspective, watersheds can be considered as sets of vested interests (and social relations) within a physically defined space.  In essence, watersheds are physically defined subsets of rural society.  Actors with vested interests within watersheds are interdependent because of water flow...

The Role of Cooperatives in Communities: Examples from Saskatchewan
Provedor de dados: 31
Autores: Fulton,   Murray E.; Ketilson,   Lou Hammond.
This paper examines the role of cooperatives in the economic and social development of communities in Saskatchewan, a prairie province of Canada. Based on a comprehensive study of cooperatives in that province, it provides statistical evidence of the economic importance of cooperatives and anecdotal evidence from interview that demonstrates the value of cooperatives in contributing to the social well-being of residents and in maintaining a sense of community. It also posits a number of theoretical models that can be used to explain the role of cooperatives in communities. A major finding is that cooperatives play a critical role in ensuing the continued social and economic existence of many communities, particularly smaller communities facing rural decline.

DO INCREASED COMMODITY PRICES LEAD TO MORE OR LESS SOIL DEGRADATION?
Provedor de dados: 31
Autores: LaFrance,   Jeffrey T.
In this paper, a dynamic economic model is used to analyze the conflicting impacts of crop increasing/land degrading inputs with those of soil conserving/crop reducing inputs in problems of soil degradation in agriculture. Soil is a renewable resource that is generated naturally at a slow, essentially autonomous rate. Cultivation enhances crop production and degrades the soil, while conservation is unproductive for the crop but improves the soil resource. If the effects of cultivation dominate the effects of conservation in the soil dynamics, an increase in the price of the crop accelerates the rate of soil degradation In the short-run and decreases the long-run stock of the soil resource. On the other hand, if the effects of conservation dominate the...

FORECASTING CATTLE PRICES IN THE PRESENCE OF STRUCTURAL CHANGE
Provedor de dados: 31
Autores: Goodwin,   Barry K.
Recent empirical research and development in the cattle industry suggest several reasons to suspect structural change in economic relationships determining cattle prices.  Standard forecasting models may ignore structural change and may produce biased and misleading forecasts.  Vector autoregressive (VAR) models that allow parameters to vary with time are used to forecast quarterly cattle prices.  The VAR procedures are flexible in that they allow the identification of structural change that begins at an a priori unknown point and occurs gradually.  The results indicate that the lowest RMSE for out-of-sample forecasts of cattle prices is obtained using a gradually switching VAR model.  However, differences between the gradually switching VAR model and a...

Political Economy of Structural Adjustment: A General Equilibirum- Interest Group Perspective
Provedor de dados: 31
Autores: Roe,   Terry L.
Economic policy, policy reform and sustainability are viewed as a political- collective action process. The challenge is to provide incentives for collective action that yield an efficient allocation of a country's resources and to prevent the reemergence of the old policy regime once a crises is resolved. A modified Ricardo-Viner model with rent seeking households is used to provide insights into the factors that cause action to be misdirected, and into how policy reform might be induced and sustained. The analysis suggests the use of instruments that decrease the scope for rent seeking, provide resources - in the form of public goods - to the less influential, and compensatory payments to those disadvantaged by reform. Several recent IBRD and IMF country...

MULTIPLE-OUTPUT PRODUCTION MODELED WITH THREE FUNCTIONAL FORMS
Provedor de dados: 31
Autores: Villezca-Becerra,   Pedro A.; Shumway,   C. Richard.
Aggregate dual models are specified to examine multiple-output production relationships in each of four major, geographically dispersed, agricultural states (California, Iowa, Texas, and Florida). Three locally-flexible functional forms (translog, generalized Leontief, and normalized quadratic) are employed to conduct analytic simplification tests, estimate systems of output supply and input demand equations consistent with nonrejected hypotheses, derive elasticities, and determine to what extent analytic simplification tests and policy-relevant results are sensitive to functional form and state. Important differences in empirical implications were found due both to functional form and geographic unit, but differences were greater for the latter.

Sustainable Development and Economic Growth in the Amazon Rainforest

Autores: Nogueira,   Jorge Madeira; Kyle,   Steven C.
This paper analyzes the implications of the concept of sustainable development for economic growth. Most definitions of "sustainability" currently in use provide little guide for policy while some would in fact work against the process of development if they were to be operationalized. The difficulties in promoting "sustainable development" in the context of a growing economy where there is a large segment of the population living in absolute poverty are illustrated with the case of the Brazilian Amazon.

IMPLICATIONS OF RAISING THE NONFAT SOLIDS STANDARDS FOR BEVERAGE MILK
Provedor de dados: 31
Autores: Salathe,   Larry E.; Price,   J. Michael.
An econometric model of the dairy industry was used to estimate the effects on farmers, consumers, and taxpayers of nationwide adoption of the California nonfat solids standards for fluid milk. It was estimated that adoption of the California standards would raise farm-level milk prices by 1 to 5 percent in the short run and by 1 to 2 percent in the long run. The average retail price of fluid milk would rise by 9 to 13 cents per gallon. Dairy program costs fall under most scenarios, but could rise if surpluses fall to levels that would trigger increases in the support price.

THE SUPPLY OF NON-DEGRADED AGRICULTURAL LAND

Autores: Clarke,   Harry R.
Profitability increases because of favourable product or factor price changes provide incentives for profit-maximising farmers, who use soils in conjunction with other cooperant inputs, to increase their investment in the preservation of soil-quality, whenever there exist economically viable technologies for preserving soils. However, when such technologies do not exist, regardless of whether farmers utilise soils as non-renewable or renewable resources, such profitability increases are associated with a long-run deterioration in soil quality.

PEASANT COOPERATION FOR WATERSHED MANAGEMENT IN MAISSADE, HAITI: FACTORS ASSOCIATED WITH PARTICIPATION

Soil erosion is an important contributor to the agricultural decline, poverty, and emigration which characterize rural Haiti today.  The numerous soil conservation projects have often ignored indigenous knowledge, techniques and socio-cultural institutions and have not generally resulted in sustained conservation.  Limited adoption rates have supported widespread assumptions that peasants were noncooperative, individualistic actors who required substantial external incentives for changing land use behavior.  An alternate strategy was utilized in Maissade, Haiti, where peasants now cooperate to treat small, multiple-owner watersheds.  Field research was conducted to understand the cooperative action and the socio-economic factors associated with...

Autores: LeBlanc,   Michael; Hrubovcak,   James; Durst,   Ron L.; Conway,   Roger K.
The Tax Reform Act of 1986 significantly changed incentives for investing. This analysis specifically examines how changes in marginal tax rates, depreciation schedules, and the investment tax credit altered the cost of capital and net investment in agriculture. A stochastic coefficients econometric methodology is used to estimate an investment function which is then used to simulate the effects of tax reform. Estimates indicated that relative to prior law, the Tax Reform Act will reduce the capital stock of farm machinery and equipment by nearly $4 billion.

The growth rate of the United States' agricultural exports to its trading partners was predicted using some measures of each country's past macroeconomic conditions. The model which applies a five-year lag basis predicted better than that which utilizes a ten-year lag. Results show that the significant determinants of the growth rate of U.S. agricultural exports include the importing countries' GDP growth rate, agricultural self-sufficiency, population density, and distance from the United States.

A RE-EXAMINATION OF EVENT STUDIES APPLIED TO CHALLENGED HORIZONTAL MERGERS
Provedor de dados: 31
Autores: Hopkins,   Yvette S.; Connor,   John M.
A growing body of empirical studies have been interpreted as support for a laissez-faire policy towards mergers. These "event studies" examine the reaction of stock market prices of firms that announce an agreement to merge. The type ~f reaction reveals whether a merger is motivated by a desire for market power or purely to improve market efficiency. In this paper, a version of the capital asset pricing model (CAPM) is applied to determine if abnormal returns are earned by rivals of 22 pairs of firms whose attempted horizontal mergers were challenged by the federal antitrust agencies. At most eight, and possibly only five, of the cases were found to be motivated by efficiency in seeking merger, and at most six, and possibly only one, were motivated by...

THE VALUE OF REDUCING TEMPORAL INPUT NONUNIFORMITIES
Provedor de dados: 31
Autores: Babcock,   Bruce A.; Blackmer,   Alfred M.
The producer value of reducing temporal uncertainty concerning the level of soil nitrate is estimated for corn production in Iowa. The reduction in uncertainty is obtained through use of a late-spring nitrate test. Parametric representations of conditional densities of soil nitrates are used along with an estimated production function to estimate optimal nitrogen fertilizer applications under both uncertainty and certainty for a representative risk-neutral Iowa corn farm. Results indicate that decreasing uncertainty could reduce average fertilizer applications by up to 38% and that producer returns could be increased by up to $22.08/acre.

A model and associated formulae are developed to estimate the size and distribution of benefits generated by different types of research for the Australian dairy industry. Particular attention is given to the influence of policy interventions on the estimates. The estimates of aggregate research benefits differ for free market assumptions versus current policy assumptions, but quantitatively the differences are small. By contrast, estimates of the distribution of benefits between different groups of consumers and farmers are significantly altered by the policy interventions.

Rum Corps to IXL: Services to Pastoralists and Farmers in New South Wales, Part IV 1930-1990: Depression, War and Peace
Provedor de dados: 31
Autores: Davidson,   Bruce Robinson.
The depressed prices of agricultural commodities and the decline in farm incomes in the 1930s destroyed farmers' and governments' belief in a free market for a generation. In spite of the rapid development and introduction of new farming techniques after the Second World War, and the consequent increases in productivity, farmers were unwilling to allow demand and supply to determine product prices and insisted on government intervention in the market for agricultural commodities, credit and some inputs. The supply of agricultural services in the first two post-war decades was dominated by such intervention, and in the next two decades by attempts by the state to reduce its intervention in the market, a process which was not completed by 1990.  Although the...

An Integrated Approach to Modeling Price Volatility in the Live Cattle Futures Market
Provedor de dados: 31
Autores: Evans,   Kevin J.; Streeter,   Deborah H.; Hudson,   Michael A.
An understanding of changes in price volatility is of value to policy makers and exchange committee members as well as other participants in commodity futures markets. Previous research has studied volatility by measuring: 1) the flow of new information into the market, or 2) the effect that the structure of the futures market has on price volatility. In this paper, a model is developed which integrates these two themes in the literature to measure and explain price volatility in live cattle futures prices. The model is subjected to a battery of diagnostic tests so that a comparison can be made between the integrated model and models from previous research. Also, since price volatility from the underlying commodity is a major component in the determination...

This paper explores changes in traditional commodity programs from the perspective of domestic welfare.  A theoretical model was developed which describes domestic welfare changes that follow from policies consistent with reductions in international price distortions.  The model was applied to the 1985 Farm Bill.  This provided an historical example of a policy change that simultaneously improves domestic welfare and reduces protectionism.

Orange Juice: A Private Label Product for the Nineties?
Provedor de dados: 31
Autores: Zellner,   James A.
Orange juice began as a branded product in the 1950s, but private and packer labels son became dominant.  Brands gained share during the 1980s with the introduction of a third national brand and the growth of chilled juice.  The large number of packer labels makes brand and private label share measures misleading for structure-performance studies.  Private label appeals to manufacturers who like the lower risk, the absence of slotting allowances, and fewer entry barriers.  Pasteurized orange juice, however, the newest product form to experience rapid private label growth, is uncharacteristic because of large capital investment required for efficient market entry.

REGIONAL ACREAGE RESPONSE FOR U.S. CORN AND WHEAT: THE EFFECTS OF GOVERNMENT PROGRAMS
Provedor de dados: 31
Autores: Chembezi,   Duncan M.; Womack,   Abner W.
This paper presents findings from an analytical scheme that offers a promising alternative to traditional procedures of modeling acreage response.  The scheme addresses the two-step decision process in which program and nonprogram planting decisions are modeled separately, conditional on the decision to participate.  This provides a more realistic and intuitive portrayal of producers’ decision making process.  The model is applied at the regional level to assess the impact of farm programs on acreage response for corn in the Cornbelt and Lake States, and for wheat in the Northern Plains.  The impacts of policy variable changes on participation and planted acreage are also analyzed.

The growth in the railway network in the 1880s and 1890s and the development and adoption of new farming techniques changed the semi-subsistence selector in New South Wales (NSW) into a commercial farmer. They also led to a large increase in the production of wheat and dairy produce and, together with overgrazing in the Western Division, caused a complete relocation of the main types of farming in NSW.

The Integrated Farm Management Program Option (IFMPO) of the 1990 farm bill is designed to increase crop management flexibility and promote the use of resource-conserving crops. Economic analysis of this program indicates that, although the current format provides flexibility, it provides little economic incentive to adopt resource-conserving crop rotations.

A COMPARISON OF SUBJECTIVE AND HISTORICAL CROP YIELD PROBABILITY DISTRIBUTIONS
Provedor de dados: 31
Autores: Pease,   James W.
Forecast distributions based on historical yields and subjective expectations for 1987 expected crop yields were compared for 90 Western Kentucky grain farms.  Different subjective probability elicitation techniques were also compared.  In many individual cases, results indicate large differences between subjective and empirical moments.  Overall, farmer expectations for 1987 corn yields were below those predicted from their past yields, while soybean expectations were above the historical forecast.  Geographical location plays a larger role than crop in comparisons of relative variability of yield.  Neither elicitation technique nor manager characteristics have significant effects on the comparisons of the forecasts.

POTENTIAL MARKETS FOR OKLAHOMA PRODUCE: A MARKET WINDOW ANALYSIS
Provedor de dados: 31
Autores: Henneberry,   Shida Rastegari; Kang,   Taehoon.
Market windows were examined in five wholesale markets for Oklahoma bell peppers, broccoli, cantaloupes, cauliflower, sweet potatoes and watermelons. "Market window" refers to a period of time when the prices received by producers for selected crops are greater than the production costs. The analysis is based on price-cost comparisons in major wholesale markets. Price risk associated with price variability and yield risk was incorporated into the analysis. The Denver and New Orleans wholesale markets provide excellent market windows for all six crops. The Chicago and Dallas wholesale markets show good market potential for most of the crops.

Characteristics and Performance of New York Dairy Farms
Provedor de dados: 31
Autores: Jack,   Kevin E.; Knoblauch,   Wayne A.; Novakovic,   Andrew M.
A combination of a more punitive policy situation and the greater range in size and financial performance in farms, especially across regions, has led to policy-makers focusing more on how new policies or policy proposals affect regions or types of farms, not just the national aggregates or average. While some new research is focusing on the implications of policy changes on farms in different areas and of different sizes, less has been done to improve how one goes about identifying and defining a "representative" farm. The basic objective of this study is to explore the relationship between structural, technical efficiency, and financial performance data for a large sample of New York dairy farms. To what extent are financial or technical performance...

MEASURING USE VALUE FROM RECREATION PARTICIPATION
Provedor de dados: 31
Autores: Whitehead,   John C.
Recreation demand studies have traditionally utilized a two-step valuation method, estimating condtional recreation participation probabilities and then intensity of use decisions.  These two steps of analysis are combined to estimate the use value of natural resource recreation sites.  The purpose of this paper is to provide a method by which use value can be estimated solely from the participation decision.  The one-step resource valuation method allows estimation of use values from coefficients of the logistic regression recreation participation equation.  The benefits of the method are the reduced data and effort required to value natural resource areas.

Clearly, the question which is the workshop title permits of no single simple answer. This paper addresses it in the particular context of taxation. The argument is that in this context the sustainability debate seems to have had rather little effect on economists' thinking and policy advice. While it is true that taxation is looked upon more favourably than some alternative instruments for environmental policy implementation, there does not appear to have been much in the way of thinking about. or policy advice on, taxation per se in the context of concern for sustainability promotion.

Concepts associated with stochastic process containing multiple transition matricies are discussed. It is proved that under certain conditions, a process with m transition matrices has m unique limiting probability vectors. This result extends the notion of discrete Markov processes to problems with intrayear and interyear dynamics. An example using a large DP model illustrates the usefulness of the concepts developed to applied problems.

New Product Procurement: A Summary of Buying Practices and Acceptance Criteria at U.S. Supermarket Chains
Provedor de dados: 31
Autores: Fredericks,   Peter J.; McLaughlin,   Edward W.
The introduction of new products to U.s. supermarkets is a business function with significant implications for all food system participants -from manufactures and supermarket retailers to consumers. In 1991 over 16,000 new items were introduced into the U.s. grocery distribution system, more than a 1,000 percent increase from the average number of annual introductions during the 1970s. Despite the magnitude of product introductions, and given the central role supermarket buyers play in the ultimate success or failure of manufacturers' new products, the new product procurement process of U.s. supermarket chains has comparatively been little researched. The intent of this study was to examine the new product review process of U.s. supermarket chains and...

Economic analysis was conducted on hypothetical agronomic research on new crop cultivars for Arkansas dryland soybean and wheat producers.  In relation to farmers’ attitudes toward risk, the microeconomic effects and level of adoption of yield variability reducing cultivars were analyzed utilizing a production management decision-making model formulated with mathematical programming techniques.  The study indicated that negative covariance between crops continues to be an effective means of reducing production risk associated with yield variability.  However, under varying circumstances, agronomic research on the breeding of new soybean and wheat cultivars with reduced yield variability is worthwhile if there is only slight concurrent reduction in expected...

An eleven-region stochastic coefficient econometric model was estimated and used in an optimal control framework to evaluate the effectiveness of the dairy price support program and marketing orders in reducing and stabilizing government purchases of dairy products. The results showed significant pressure on the reduction of the support price  both in the presence and absence of Class I differentials. The optimal control model also showed that the drop in price support levels did not dramatically alter the regional distribution of milk production.

The effect of capital structure and seasonality of fresh market vegetables was examined via the Target MOTAD model.  The level of capital indebtedness and the selection of either a fall or spring season resulted in significantly different levels of enterprise mixes, expected returns, risk magnitudes, rates of change of risk magnitudes, and operating capital requirements.  The fall season demonstrated larger initial levels of risk and larger increases in the level of risk due to increases in indebtedness.  The spring season showed larger increases in risk between minimum risk point and the maximum expected return point (linear programming solution) on the risk-efficient frontier.  Operating capital requirements were substantially higher for the fall season...

Assessing Model Assumptions in Trade Liberalization Modeling: An Application to SWOPSIM
Provedor de dados: 31
Autores: Herlihy,   Michael; Haley,   Stephen L.; Johnston,   Brian G.
This report reviews research on the effectiveness of acreage reduction programs and describes the methodology developed for the Static World Policy Simulation (SWOPSIM) modeling framework to capture the effect of removing these programs. It also analyzes the results of several sensitivity tests of a SWOPSIM model used by the Economic Research Service to study the effects of agricultural trade liberalization. Assumptions concerning how U.S. acreage reduction programs are modeled significantly influence predictions as to how trade liberalization affects commodity prices, production, and trade. However, these assumptions do not significantly influence predictions of how trade liberalization affects producer welfare. In terms of trade liberalization analysis,...

ECONOMIC IMPLICATIONS OF GLOBAL CLIMATE CHANGE FOR WORLD AGRICULTURE
Provedor de dados: 31
Autores: Tobey,   James A.; Reilly,   John M.; Kane,   Sally.
This paper challenges the hypothesis that negative yield effects in key temperate grain producing regions of the world resulting from global climate change would have a serious impact on world food production. Model results demonstrate that even with concurrent productivity losses in the major grain producing regions of the world, global warming will not seriously disrupt world agricultural markets. Country/regional crop yield changes induce interregional adjustments in production and consumption that serve to buffer the severity of climate change impacts on world agriculture and result in relatively modest impacts on world agricultural prices and domestic economies.

WHICH COUNTRY LOSES THE LEAST IN A TRADE WAR?
Provedor de dados: 31
Autores: Gaisford,   James D.; Kerr,   William A.
Trade actions, which can generally be claimed as trade wars, appear to be on the rise. This is particularly true in the case of agricultural commodities. It is a common perception that large countries will be the victors in such contests and this clearly affects the trade strategies of small countries, including Australia. The relationship between free-trade and trade-war pay-offs in the context of a prisoner's dilemma is explored in this paper. It is shown why neither a favourable terms of trade movement, a flatter import demand curve nor a larger population is, on its own, a sufficient condition for a relative victory in a trade war. The implications for small country trade strategies are then discussed.

MARKET IMPACTS OF BOVINE SOMATROPIN: A SUPPLY AND DEMAND ANALYSIS
Provedor de dados: 31
Autores: Kaiser,   Harry M.
The potential economic impacts of the introduction of bovine somatotropin (bST) on U.S. milk supply and demand are analyzed using a national model of Class I and Class II milk markets.  The results indicate that the introduction of bST will lead to lower milk prices, higher milk production, and larger government purchases of dairy products.  Unlike previous economic analyses of bST, this analysis considers both supply and demand effects of bST.  The implication is that studies that ignore potential demand-side effects may produce misleading results.

AN ECONOMIC EVALUATION OF SOYBEAN STINK BUG CONTROL ALTERNATIVES FOR THE SOUTHEASTERN UNITED STATES
Provedor de dados: 31
Autores: Chyen,   David; Wetzstein,   Michael E.; McPherson,   Robert M.; Givan,   William D.
Methyl parathion or Penncap M (an encapsulated methyl parathion) are used extensively throughout the United States for controlling stink bug pests in soybeans, Glycine Max (L.) Merrill.  However, this insecticide is highly toxic to mammals, birds, and non-target arthropods, and thus is less environmentally sound than other insecticides.  For environmental and human health considerations, investigating alternative insecticides for control is desired.  For this investigation, research based on field experimental data from Florida, Georgia, and Louisiana during the 1988 and 1989 growing seasons were employed.  Results indicate that alternative, currently available, and less toxic insecticides may reduce producer costs, increase yield, and improve soybean...

USDA DATA REVISIONS OF CHOICE BEEF PRICES AND PRICE SPREADS: IMPLICATIONS FOR ESTIMATING DEMAND RESPONSES
Provedor de dados: 31
Autores: Marsh,   John M.
Reduced form price equations were estimated to compare market demand responses from two data sources: U.S. Department of Agriculture (USDA) beef price and price spread data per revisions in 1978 and per revisions in 1990. The latest revisions were necessary to account for changing beef industry technology and product consumption in the 1980s. Results indicate the elasticities of retail and derived demands average about 25 and 17% lower, respectively, when using the 1990 revised data. Trends and lag adjustments played an important role. The analyses suggest careful interpretation of demand responses when time series data lag technology conditions in the market.

THE POLITICAL ECONOMY OF AGRICULTURAL TRADE NEGOTIATIONS ON THE URUGUAY ROUND OF MTN: CAN THE U.S. AND EUROPEAN COMMUNITY REACH AN ACCEPTABLE COMPROMISE IN THE GATT?
Provedor de dados: 31
Autores: Ames,   Glenn C.W.
A model of the political economy of agricultural policy formulation was used to analyze the current stalemate in the Uruguay Round of Multilateral Trade Negotiations. The combination of social welfare increasing and transferring policies in the European Community and the U.S. is one of the primary causes of the deadlock in trade negotiations. The Community's farm policy of high internal price supports, limited market access, and export subsidies represents short-term equilibria in the market for social-welfare policies which distribute benefits to producers at the expense of consumers and taxpayers. Thus, the opportunity for internal reform of the CAP leading to a compromise in the GATT negotiations is problematic at best. However, international...

PRODUCTION RELATIONSHIPS IN SOUTH CENTRAL AGRICULTURE
Provedor de dados: 31
Autores: Polson,   Rudolph A.; Shumway,   C. Richard.
Output supplies and input demands were estimated for each of five South Central states. The model structure in each state was based on prior parametric tests of homothetic separability, and estimates were generally consistent with a competitive, profit-maximizing industry. Considerable diversity among states was evident in selected production relationships. These results further document the non-uniform ways in which producers respond to government farm programs and market information.

The value of a nation's currency is the most important price in its economy. Attempts to establish or maintain fixed exchange rates between countries are no longer possible due to the sheer size of international financial markets. The value of a nation's currency not only influences the relative prices between its tradeable and nontradeable sectors, it influences in very important ways a country relates to the rest of the international economy. The most significant effect of cyclical swings in exchange rates is the impact on trade where undervalued currencies amount to an export subsidy and an import tariff. U.S. foreign aid programs tend to strengthen the recipient country's foreign currency but hurt its development efforts. Needed stability in exchange...

Rates and Patterns of Change in New York Dairy Farm Numbers and Productivity
Provedor de dados: 31
Autores: Smith,   Stuart F.
Dairy farm numbers are declining in nearly every region and county of New York State but the rate of decline varies between years and counties. Converting inefficient or unprofitable farm resources to nonfarm use is part of the adjustment process. New York dairy counties are at different stages of this process. Increasing dairy farm productivity to remain economically viable and competitive is also part of the adjustment process. Fifteen of New York's 23 largest dairy counties have increased average milk output per farm at rates greater than the State average. The dairy farming industry in these counties is in the most competitive position.

A STOCHASTIC SIMULATION ANALYSIS OF A SMALL-SCALE CATFISH PROCESSING PLANT
Provedor de dados: 31
Autores: Branch,   William; Tilley,   Daniel S.
Stochastic simulation was used to analyze revenues and costs for a small-scale catfish processing plant under various combinations of operating capacity utilization and price paid for live fish. The probability for a positive level of daily net income ranged from 11 to 100 percent depending on the price paid for live fish and level of operating capacity utilized. Daily average total cost per pound of live fish processed changed by 2.10 percent given a 10 percent change in live fish processed. Short-term cyclical patterns in revenues and costs suggest a need for financial planning to provide for possible year-end revenue shortfalls.

NON-TARIFF MEASURES AND INDUSTRIAL NATION IMPORTS OF AGRICULTURAL PRODUCTS

Autores: Clark,   Don P.
Trade coverage ratios were calculated to assess the 1989 incidence of non-tariff measures (NTMs) on imports of agricultural products by major industrial nations.  Overall, 36 percent of all food items were found to be covered by one or more NTM in the European Community.  Corresponding figures for Japan and the United States were 59 and 17 percent, respectively.  Imports of agricultural products confront a wide variety of NTMs in markets of industrial nations.  Results of the analysis were used to shed light on prospects for reaching agreements on agricultural reform issues in the Uruguay Round of multilateral trade negotiations

CASH FORWARD CONTRACTING VERSUS HEDGING OF FED CATTLE, AND THE IMPACT OF CASH CONTRACTING ON CASH PRICES
Provedor de dados: 31
Autores: Elam,   Emmett W.
This research examines cash forward contracting of fed cattle. For an individual feeder, a cash contract eliminates basis risk (as compared to a futures hedge). However, the disadvantage is that the contract price is estimated to be lower than the futures hedge price by $.28 - $.59/ cwt for steers and $.86 - $1.64.cwt for heifers. From the industry perspective, contracting appears to have a negative impact on cash prices. An increase of 1,000 head in U.S. monthly contract cattle shipments is associated with a $.003—$.009/cwt decrease in the U.S. average cash price. The negative impact of cash contracting varies by state.

An Economic Analysis of Soil Erosion Control and Low-Input Agriculture
Provedor de dados: 31
Autores: Diebel,   Penelope L.; Taylor,   Daniel B.; Batie,   Sandra S.; Heatwole,   Conrad D.
The Chesapeake Bay is a major water resource whose quality has been threatened by soil erosion and agrichemical contamination. The control of agricultural pollution of the Bay is one of the focal points of the 1987 Chesapeake Bay agreement formed by four states in the Bay's watershed (Virginia, Maryland, Pennsylvania, and the District of Columbia). Among the suggested solutions is the promotion of low-input agricultural practices. However, some low-input practices also include frequent cultivations of the soil for non-chemical weed control practices, which may induce erosion. This analysis uses a case study approach to determine agricultural practice selection and potential erosion under different soil erosion constraints. A multi-period mathematical...

The primary objective in this paper is to 'promote' the use of equilibrium displacement modeling, or comparative static analysis of general function models, as a research tool in agricultural price and policy analyses. This is by no means a new tool, but it does seem to be used much less in Australia than it is in the US where it has been the basis of several important journal papers in recent times, The paper includes applications to: (a) reproduce important results obtained by Euse (1958) regarding total elasticities; and (b) examine the price premium argument that has been advanced in favour of single-desk selling arrangements. The latter is the secondary objective in the paper. Whilst equilibrium displacement modelling has its shortcomings, it is a...

A Critique of Computable General Equilibrium Models for Trade Policy Analysis
Provedor de dados: 31
Autores: Hazledine,   Tim.
The paper will deal in turn with three sets of modelling issues: the question of 'data'; the 'micro' problem of specifying market behaviour, and the. 'macro' issue of 'closing' the models in aggregate. I will conclude with some suggestions for future research. The basic theme of the paper is this: CGE modelling is essentially a conservative or 'neoclassical' scientific endeavour, and exhibits the strengths and weaknesses of neoclassicism. And as for the recent injection of apparently nonneoclassical imperfect competition or industrial organization (IO) concepts into CGE, though, as an 10 specialist myself I certainly welcome this in principle, I have doubts about the usefulness of the practice.

This summary and analysis of 407 New York dairy farm businesses demonstrates the use of cash and accrual accounting 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 III cows per farm and 18,027 pounds of milk sold per cow in 1991, 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 $26,391 per farm. The rate of return including...

INTRODUCING FOODS PRODUCED USING BIOTECHNOLOGY: THE CASE OF BOVINE SOMATOTROPIN
Provedor de dados: 31
Autores: McGuirk,   Anya M.; Preston,   Warren P.; Jones,   Gerald M.
A mailed questionnaire was used to assess consumer concerns and potential consumption response attributable to the introduction of bovine somatotropin (bST).  Responses from 605 households in Virginia are described and analyzed.  Logit models were estimated to identify which issues shape consumers’ decisions to alter milk purchases contingent on the introduction of bST and to determine whether socioeconomic characteristics explain consumers’ attitudes toward these issues.  Estimates based on survey responses point toward sizable reductions in fluid milk purchases if bST is introduced.  Large retail price reductions are predicted to be insufficient to offset these estimated decreases.  Consumer education and marketing strategies are discussed.

This study explores effects of Philippines' coconut policies on the performance in the international market.  Analysis of the coconut sector found that the Philippine government successfully changed the structure of the coconut industry during the 1970's using a fund collected as coconut levies.  Since the Philippines dominated the international trade market of coconut products, it could exercise dominant market power in the world trade, by integrating the domestic sector.  However, the industrial policies were not effective.  Results of an econometric analysis show that the Philippines did not gain the market power despite the heavy investment in the coconut sector.  Due to technological development in the oil processing sector, other oil products became...

Provedor de dados: 31
Autores: Nayga,   Rodolfo M., Jr.; Capps,   Oral, Jr.
The demand for food away from home, food at home, and non-food items is investigated using a complete systems approach. Using the linear approximation of the dynamic version of the Almost Ideal Demand System, the results indicate that the share of total expenditure going to food away from home increases as the labor force participation rate of women increases. All expenditure elasticities are positive and all own-price elasticities are negative. Moreover, the demand for food away from home is more price sensitive than the demand for food at home. Seasonal patterns of consumption are also evident.

A MULTICROP PRODUCTION MODEL OF IRRIGATED AGRICULTURE, APPLIED TO WATER ALLOCATION POLICY OF THE BUREAU OF RECLAMATION
Provedor de dados: 31
Autores: Moore,   Michael R.; Negri,   Donald H.
Recipients of irrigation water from the Bureau of Reclamation (BuRec) face a future of water conservation. By formally modeling surface water as a fixed, allocatable input to a multioutput firm, this research captures the institutional constraints governing water allocation and , simultaneously, establishes a cohesive approach to analyzing the production effects of BuRec allocation policy. Econometric results show that BuRec-served irrigators'’ crop supply and land allocation decisions are generally inelastic with respect to the water constraint. Using the elasticities, a policy simulation of a 10% reduction in BuRec water allocation indicates that production response to reduced water supply would affect the national price of three of ten major crops...

IMPORT DEMANDS FOR U.S. FRESH GRAPEFRUIT: EFFECT OF U.S. PROMOTION PROGRAMS AND TRADE POLICIES OF IMPORTING NATIONS
Provedor de dados: 31
Autores: Fuller,   Stephen W.; Bello,   Haruna; Capps,   Oral, Jr.
This study estimates import demands for U.S. fresh grapefruit in Japan, France, Canada, and the Netherlands.  Historically, these nations have imported about 90 percent of U.S. grapefruit exports.  Four import demand functions were specified and estimated by joint generalized least squares based on the sample period 1969I to 1988IV.  Results show that U.S. FOB price, per capita income of importing countries, exchange rates, price of substitutes, U.S. grapefruit promotion programs, and removal of trade restrictions have had an important effect on U.S. fresh grapefruit exports.  Analyses suggest that U.S. producers can effectively promote fresh grapefruit in foreign markets, and that trade concessions have an important influence on grapefruit exports.

The market for agribusiness extension activities and programming is diverse, intensely competitive, and national or international in scope. It is a market that agricultural economists cannot serve alone. Despite these complexities, a strong agribusiness extension effort is critical to the success of agribusiness research and teaching programs. Agribusiness extension opportunities include extending traditional agricultural economics research, small business management programs, economic/technical education programs, and management education. Keys for conducting successful agribusiness extension programs include understanding client needs, locating and employing the best instructional talent available, and flawless execution of the activity.

SUPPLY AND DEMAND FOR MARRIED FEMALE LABOR: RURAL AND URBAN DIFFERENCES IN THE SOUTHERN UNITED STATES
Provedor de dados: 31
Autores: Alwang,   Jeffrey Roger; Stallmann,   Judith I.
This study examined the supply of and demand for married female labor in the southern United States.  Special attention was given to differences in labor force participation, labor supply, and quantities of labor supplied and demanded across rural and urban areas.  Once state effects were accounted for, decisions to change participation were found not to vary by urban-rural designation.  Differences in demand were fully captured by an intercept shifter and the variations in hours supplied by married females between urban and rural areas.  Labor supply varied greatly with the effects of key determinants (number of children, work force experience, family income) being strongly different in rural areas.  Different policies are needed to promote female labor...

Autores: Kim,   Sunwoong; Mohtadi,   Hamid.
An overlapping generational model of educational investment in a dual labor markets is presented in which education serves both as a screening device and as investment in human capital. Labor market dualism arises not only via the conventional technology (productivity) differential between a primary and a secondary sector, but also by a higher than a labor market clearing wage in the primary sector, to insure no shirking by the workers (an element shared with the efficiency wage theories). The important determinants of the workers' educational investment decision are the degree of discipline in the labor market and the cost of education. Among the three most commonly discussed educational policies of maximizing the number of the educated, maximizing the...

Seasonal price premiums have been proposed as a means of dampening the highly seasonal patterns of milk production in Florida. A Markov decision bio-economic model of the breeding and replacement decisions was solved via stochastic dynamic programming and used to analyze the potential supply response to seasonal price premiums. The results of the analysis suggest that the seasonal milk supply in Florida is highly price inelastic.

Corruption! At Flemington Markets? A Case Study in Public Policy
Provedor de dados: 31
Autores: Tunstall,   Allan W.
A case study of attempts by producers to obtain market reform is presented. Important background to the case is producers traditional mistrust of middlemen and the alleged failure of government regulations to protect the interests of producers. The New South Wales Farmers Association have attacked the Markets as corrupt and riddled with fraudulent malpractice. The paper analyses the events and processes which followed these allegations. An attempt is made to obtain a better theoretical understanding of the nature of competition in the Markets. The role of the bureaucracy in perpetuating the situation through narrow adherence to simplistic economics is examined.

Water Allocation and Supply Reliability in the Murrumbidgee Valley

Autores: Jones,   Randall E.; Musgrave,   Warren F.; Bryant,   Mike.
The objective of this study is to determine the average annual income and income variance of alternative irrigation water allocations and associated supply reliabilities in the Murrumbidgee Valley. Traditionally, water supply authorities have aimed to supply irrigators with their full allocations in all but the most severe drought years. This means that a substantial amount of water is held in storage as a reserve and in most years it is not utilised for irrigation or other, including environmental, purposes. In a climate where maximum economic returns for resources are required, water supply authorities are now reconsidering this policy of high reliability with a view to expanding water use for agricultural and environmental purposes. This study uses...

AN ANALYSIS OF WILLINGNESS-TO-PAY FOR CROP INSURANCE
Provedor de dados: 31
Autores: Fraser,   Rob W.
In this paper a method for estimating a producer's willingness-to-pay for crop insurance is presented. The method includes formulae to capture the impact of crop insurance on the producer's expected income and variance of income. These impacts are evaluated in the context of a model of producer welfare which features both price and yield uncertainty, as well as risk aversion on the part of the producer. The method is applied to the Australian wheat industry and estimates of willingness-to-pay are shown to be relatively sensitive to the levels of coverage and yield variability.

Six measures of returns are used to estimate the most "“appropriate"” market index for southeast Kansas farms. Results suggest that localized indices are more appropriate than state indices for use as the market index. The appropriate index was used to estimate systematic and nonsystematic risk and risk costs for farm planning. Estimated risks depend on the choice of market index, whereas risk costs depend on the index choice and the risk aversion are considered. More risk-averse specialized farmers are not completely compensated for risk.

Discounting and Sustainability

The discounting of future benefits has long been one of the most controversial, and in many ways, unsatisfactory, aspects of benefit -cost analysis. This concern has been heightened by the rise of the environmental movement and, particularly by the debate over sustainable development. The sustainability approach is presented as an alternative to the standard benefit-cost analysis approach to the question of inter-generational equity.  Sustainability is in fashion, and, as with all fashionable terms, it has been used in many ways and in support of many different policy agendas. A summary and critique of the literature is given by Ule (1991). I shall interpret sustainability very broadly to encompass two main concerns:  (i) The interests of future...

WHAT IS A WETLAND WORTH? CONCEPTS AND ISSUES IN ECONOMIC VALUATION
Provedor de dados: 31
Autores: Taff,   Steven J.
A wetland has no economic value in and of itself. Nor does it have a unique value, irrespective of context. Economic value is ascribed to a wetland by humans operating at a confluence of individual preferences, property rights, technological opportunities, and available resources. Such values are not generally reflected in market prices, a deficiency that can nonetheless addressed by competent economic analysis, using a variety of empirical techniques. The task is complicated by scientific information shortfalls, by ever-changing technologies and economies, and by evolving societal preferences--but it can be done. Economic valuations have been used in wetland priority rankings and in comparative investment analyses.

DIRECT PRODUCE PROFIT FOR SMALL AND INTERMEDIATE SIZE GROCERY RETAILERS
Provedor de dados: 31
Autores: Blanchard,   Michelle Roberts; Criner,   George K.
Direct product profit (DPP) is a retailing tool used to analyze product sales performance. Although the concept is over 20 years old, its widespread use in grocery stores is a fairly recent phenomena. A product's DPP is calculated as its adjusted gross margin less its direct selling costs, which normally include transportation, warehousing, and retailing or store costs. A product's DPP and sales volume classifies it in one of four categories to assist in merchandising options.  Fifteen small and intermediate size grocery retailers cooperated with a study of produce DPP. Based on weekly produce sales, the stores were separated into three groups. As store group produce sales increased, produce adjusted gross margin and DPP increased. Based on produce sales...

Autores: Smith,   Stephen M.; Bodenman,   John E.; Jones,   Stephen B.
This study's objective is to identify and understand the factors important to hardwood processors' location decisions in the northern and central Appalachian region.  Concepts from neoclassical and behavioral location theories were integrated to develop a general framework for analyzing these decisions.  Logit regression analysis was used to determine those establishment characteristics related to the likelihood of location search.  To a great extent, establishments locate based on personal ties and do not conduct searches.  Most variables found to influence the likelihood of search are not controllable by state or local governments.  The implications are that existing establishments should be targeted for retention and expansion, rather than focusing on...

The presence or absence of structural change in meat demand is critical to marketing decision making. If change is present, marketing bodies need to know what underlies the change so that the most appropriate response can be identified. Marketing theory is considered as a possible source of more explicit models of demand which may lead to a better understanding of consumption patterns and structural change.

Labor's Final Rural "Crisis"?: Australian Rural Policy in 1990 and 1991

Autores: Gerritsen,   Rolf.
Rural policy-making came under increasing pressure during 1990 and 1991 as a rural downturn rivalling the 1982-83 drought eroded farm incomes. International trade reform was stalled, the government procrastinated during the wool crisis and continued to be tardy in delivering the benefits of microeconomic reform to the agricultural sector. Also the liberal/National Coalition parties finally rallied to provide a coherent and credible alternative government All these developments, plus a series of policy reverses, portended that this was probably Labor's final "rural crisis".

Response to changes in factors influencing consumption of catfish and competing commodities differ between national, South Atlantic, and Southwest Central markets. A modified state adjustment model for catfish, beef, chicken, and other fish explicitly included age distribution, residence, occupation, education, and race/ethnic variables associated with habit formation. Nationally, per capita expenditures on catfish respond to present and past relative prices, and catfish, chicken, and other fish, but not beef, consumption demonstrates significant habit formation. South Atlantic and Southwest Central habits for catfish consumption persist, and, as the population ages, chicken and fish consumption increase.

This article investigates the possible negative effects of bovine somatotropin (bST) and antibiotic use in cows on fluid-milk consumption in New York State.  Based on data from a consumer survey, the potential change in milk consumption due to bST and antibiotic use is estimated.  In addition, the current perceptions of consumers about bST and antibiotics are measured, and the significant socioeconomic, demographic, and attitudinal characteristics of consumers that are related to their milk-consumption response to bST are identified.  Depending upon consumer awareness of bST, the results indicate that milk consumption in New York State could decrease by 5.5% to 15.6% if bST is approved.  The results also suggest that antibiotic use in cows could decrease...

Quadratic flexible forms, such as the translog and generalized Leontief, are separability inflexible. That is, separability restrictions render them inflexible with regard to separable structures. A class functional forms is proposed that is flexible with regard to general production structures and remains flexible regarding weakly separable structures when separability restrictions are imposed, thus permitting tests of the separability hypothesis. Additionally, the restricted forms are parsimonious; that is they contain the minimum number of parameters with which flexibility can be achieved.

MODELING THE EFFECT OF UNCERTAINTY ON TIMBER HARVEST: A SUGGESTED APPROACH AND EMPIRICAL EXAMPLE
Provedor de dados: 31
Autores: van Kooten,   G. Cornelis; van Kooten,   R.E.; Brown,   G.L.
A method is suggested for modeling uncertainty when there is a lack of information concerning the effect of forest management decisions on tree growth. Dynamic programming is used to investigate the optimality of alternative management strategies. The model is illustrated with an empirical example for a boreal forest region of western Canada. Three tentative conclusions follow: (a) silvicultural strategies to reduce uncertainty or to increase stand growth may not be worth pursuing, at least in northern forests; (b) the discounted cost of ignoring uncertainty may be substantial if taken over the entire forest; and (c) given uncertain forest growth, flexible harvest policies are preferred to a fixed harvest age.

A REVIEW OF RECENT CHANGES IN MEXICAN AGRICULTURAL POLICY:  IMPLICATIONS FOR SMALL SCALE BEAN PRODUCTION
Provedor de dados: 31
Autores: Bryant,   Elizabeth.
Until the early 1980s, Mexican economic policy was characterized by import substitution industrialization. Agriculture's role was to provide a cheap and abundant food supply for the urban sector, and to generate foreign exchange through exports. While Mexico achieved food self-sufficiency by the early 1960s, conflicting policies succeeded in undermining basic grain production and exacerbating an existent dichotomy between traditional and rainfed production. Austerity measures imposed during the 1980s resulting from the collapse of world oil prices further undermined small-scale production.   These effects are viewed in the context of the bean subsector, characterized by a bimodal system of production; while the majority of Mexican bean producers are...

AN EMPIRICAL APPLICATION OF LABORATORY EXPERIMENTAL AUCTIONS IN MARKETING RESEARCH
Provedor de dados: 31
Autores: Menkhaus,   Dale J.; Borden,   George W.; Whipple,   Glen D.; Hoffman,   Elizabeth; Field,   Ray A.
A laboratory experimental auction was used to determine factors influencing the relative value consumers place on alternative retail beef packaging. Results indicate information is very important for the successful introduction and marketing of the vacuum skin package. Physical appearance of the beef plays a major role in purchasing decisions by consumers, with fat and shape significantly decreasing the value of beef in the vacuum skin package relative to beef in the overwrapped styrofoam tray package. Experimental economics procedures, when combined with traditional marketing research techniques, can provide useful information for marketing decisions and economic analyses.

Grain Marketing Cooperatives' Adjustments to Farm Programs
Provedor de dados: 31
Autores: Gunn,   Steven P.; Cobia,   David W.
A personal interview survey of 87 grain marketing cooperatives regarding the impact of changes in government programs and planned responses to the dilemma of excess capacity and loss of government storage income and related factors is reported. Government storage payment's impact on financial performance was ranked 77% more important than the second (other government programs) of 7 factors (e.g., interest rates). Government storage accounted for 20% of their net income. They acquired an average of 800,000 bu. of storage capacity in response to government programs. PIK and roll increased annual income an average of $39,000 in 1986-87. Participation in CCC weekly auctions averaged 51% and in catalog sales 87%. Most managers felt that government programs did...

Tradeoffs Between Water Quality and the Economic Impacts of Low-Input Agriculture in the Coastal Plain of Virginia
Provedor de dados: 31
Autores: Diebel,   Penelope L.; Taylor,   Daniel B.; Batie,   Sandra S.; Heatwole,   Conrad D.
Agricultural activities have been identified as major contributors to the non-point pollution of the Chesapeake Bay. Low-input agricultural practices are being considered to reduce pollution in areas adjoining the Chesapeake Bay. A multiperiod mathematical programming model was used to examine the potential adoption of low-input practices and to assess the environmental consequences of these activities under different policies. The results of these analyses indicate that tradeoffs exist among the types of non-point pollution produced under each policy. Only policies that retired productive agricultural land reduced all pollutant types.

Estimated Impacts of a Potential U.S.-Mexico Preferential Trading Agreement for the Agricultural Sector
Provedor de dados: 31
Autores: Krissoff,   Barry; Neff,   Liana; Sharples,   Jerry A.
We develop a three region - U.S., Mexico, and Rest-of-World - simulation model to analyze the effects on the agricultural sector of a potential preferential trading arrangement (PTA) between Mexico and the United States. The simulation exercises indicate that two-way agricultural trade increases and welfare improves in the United States and Mexico from a bilateral preferential agreement on agricultural products. Our results show that when border protection is eliminated by the United States and Mexico, bilateral agricultural trade expands by over 15 percent. Relative to the size of the two agricultural sectors, however, the overall impact is very small for the U.S. agricultural sector but there is a more significant adjustment for Mexican agriculture.

Time-of-Use Rates and Electricity Costs of Representative New York Dairy Farms
Provedor de dados: 31
Autores: Boisvert,   Richard N.; Bills,   Nelson L.; Middagh,   Mark C.; Schenkel,   Mark.
Electric utilities throughout the Nation are experimenting with strategies to reduce total electricity consumption or to alter the timing of electrical power use by their customers. This report focuses on one such strategy, time-of-use (TaU) electric rates, and the likely effect of this pricing option on the New York dairy sector. The purpose of the study is to assess the change in farm electrical energy costs when power is sold to dairymen at higher rates for periods of peak power demand and at substantially lower rates for off-peak periods. This study is based on the results derived from a farm-level, computer decision model which calculates farm energy consumption by major end uses--such as milk cooling and feeding--and by time of day. The model...

Public Limited Companies and Cooperative Principles in Ireland's Dairy Sector
Provedor de dados: 31
Autores: Jacobson,   Robert E.
In recent years, several large dairy cooperatives in Ireland have been restructured in various ways into investor-oriented corporations (public limited companies). A primary reason advanced by leadership of these cooperatives for going to PLC route was that additional capital was required, and members were unwilling to invest that additional capital. The attitude of members toward cooperative investment appeared to have eroded because the principle of current active member ownership appeared to have been ignored. Net income was not allocated, and equity redemption policies were not in place. The argument is advanced that member investment in cooperatives can be given new incentives by bringing some dynamics to the principle of current active patron-member...

The Economic Role and Limitations of Cooperatives: An Investment Cash Flow Derivation
Provedor de dados: 31
Autores: Peterson,   H. Christopher.
The economic role and limitations of cooperatives are derived using an approach based on investment cash flows and net present value. Cooperatives are viewed as an option for member investment as well as an option for member patronage. The investment approach yields results similar to the traditional paradigms that focus on patronage. In addition, the approach makes more explicit the impact of member investment on cooperative existence, valuation, performance measurement, and strategy options.

COMPARING MODELS FOR CONTINGENT VALUATION SURVEYS: STATISTICAL EFFICIENCY AND THE PRECISION OF BENEFIT ESTIMATES
Provedor de dados: 31
Autores: Park,   Timothy A.; Loomis,   John B.
This paper empirically tested the three conditions identified by McConnell for equivalence of the linear utility difference model and the valuation function approach to dichotomous choice contingent valuation.  Using a contingent valuation survey for deer hunting in California, two of the three conditions were violated.  Even though the models are not simple linear transforms of each other for this survey, estimates of mean willingness to pay and their associated 95% confidence intervals around the mean were quite similar for the valuation methods.

Autores: Miller,   Bill R.; Mabbs-Zeno,   Carl C.
Unilateral liberalization of U.S. peanut policy was evaluated using a model of U.S. and world peanut supply and demand.  Under the proposed policy, world peanut price would rise slightly to $.20 per pound at the U.S. farm level.  U.S. production would decline by 578 million pounds per year and would be offset by imports of 582 million pounds.  U.S. net farm income would fall by $405 million per year.  Lost income per farm would be $21,000 per year while the average outlay of consumers would decrease by $.84 per person at farm level price.  Government expenditures would be virtually unchanged because of the market orientation of current policy.

COMMON PROPERTY AND COLLECTIVE ACTION: COOPERATIVE WATERSHED MANAGEMENT IN HAITI
Provedor de dados: 31
Autores: White,   Thomas A.; Runge,   C. Ford.
The paper is divided into four sections.  First, watershed management in Haiti is presented as a problem of voluntary collective action in which small watersheds are the common responsibility of a group of users.       Second, this situation is given formal expression as a "public goods" problem, in which obligations to contribute time and labor to the  maintenance and management of watersheds are treated as conditional or contingent commitments to cooperate (rather than defect).  Third, an empirical analysis is presented in which key economic and cultural factors are tested to determine those that best explain the individual propensity to cooperate and the conditions necessary for collective action to emerge.  Fourth, we interpret these results in light...

OPTIMAL RISK MANAGEMENT, RISK AVERSION, AND PRODUCTION FUNCTION PROPERTIES
Provedor de dados: 31
Autores: Loehman,   Edna T.; Nelson,   Carl H.
For production risk with identified physical causes, the nature of risk, production characteristics, risk preference, and prices determine optimal input use. Here, a two-way classification for pairs of inputs – each input as being risk increasing or decreasing and pairs as being risk substitutes or complements – provides sufficient conditions to determine how risk aversion should affect input use. Unlike the Sandmo price risk averse firm may produce more expected output and use more inputs than a risk neutral firm. Sufficient conditions to determine types for pairs of inputs are also related to properties of the production function.

CONSUMER AND FOOD INDUSTRY ACCEPTANCE OF A NEW GREEN BEAN
Provedor de dados: 31
Autores: Brooker,   John R.; Eastwood,   David B.
The perceptions of food shoppers, produce managers in supermarkets, and wholesale produce buyers were examined with respect to acceptance of a fresh green bean that is slightly darker in color than the current leading cultivar. In-store interviews with shoppers revealed that retail shoppers are not biased for or against the darker color bean. The produce department managers and wholesale buyers indicated a willingness to handle the darker bean if shown evidence that consumers would purchase them. Analysis of variance was used to search for an acceptability or preference pattern associated with various socioeconomic factors.

Autores: Liapis,   Peter S.; Shane,   Mathew.
This report presents preliminary results of impacts on factors of production in the United States, following reductions in assistance to agriculture. Analysis was conducted by modifying the production structure of the U.S. country model in SWOPSIM to explicitly include inputs employed by agriculture. The results indicate that it is important to adequately model the production technology and include inputs, otherwise simulation results may not capture the impact of liberalization on input use and may not adequately represent changes in producer income.

EVALUATING LONG-LIVED PROJECTS: THE ISSUE OF INTER-GENERATIONAL EQUITY
Provedor de dados: 31
Autores: Young,   Ralph.
The role of the discount rate in benefit-cost analysis is reviewed, and its impact considered. A positive rate clearly 'tilts the balance overwhelmingly against generations in the distant future'. In this context, the issue of inter-generational equity is discussed, and it is concluded that although a positive rate representing social time preference or opportunity cost is appropriate when considering questions of economic efficiency, this is not the case when equity questions are being examined. In the case of irreversible change, an extreme example of inter-generational inequity, there may be no alternative to a constrained optimisation approach, where the constraint is determined by an ethical decision. A range of approaches for analysing the issue of...

Autores: Edwards,   Geoff W.
The main objective in this paper is to promote thinking on what "sustainable development" or "ecologically sustainable development" means for a small trading country. After a brief acknowledgement of some of the diverse literature on sustainability, there is a consideration of some realities facing a small trading economy. The balance of the paper comprises a discussion of the scope for a small country to enhance sustainability. This is done under several headings, corresponding to different classes of resources. Although some of the discussion in the paper is couched in general terms, much of it is in the context of Australian conditions.

Autores: Menten,J.F.M.; Ku,P.K.; Miller,E.R.
Dois experimentos foram conduzidos para investigar a necessidade de suplementação de biotina na dieta de leitões recém desmamados quando o cobre é utilizado como promotor de crescimento. Rações com níveis marginais de biotina (0,10 ppm), formuladas à base de trigo e farelo de soja, foram suplementadas ou não com 0,4 ppm de biotina (BIO) e 250 ppm de cobre (COB) e fornecidas a 168 leitões desmamados com 4 semanas de idade e peso médio de 7,8 kg. Os experimentos tiveram duração de 5 semanas. No experimento 1 houve uma interação BIO x COB (P &lt; 0,05) no ganho de peso dos leitões, com BIO promovendo uma melhora de 10% na ausência de COB, mas não na presença de COB; COB resultou em um aumento de 16% no ganho de peso na ausência de BIO, mas não em sua presença...

Autores: Ono,E.O.; Rodrigues,J.D.; Pinho,S.Z. do.
O presente trabalho teve como finalidade, estudar o efeito de auxinas e do boro no enraizamento de estacas caulinares de Coffea arabica L. cv. "Mundo Novo". As estacas foram retiradas de ramos ortotrópicos semi-lenhosos de cafeeiro, as quais foram tratadas durante 24 horas com soluções de IBA ou NAA e boro, e a mistura das três substâncias, resultando um total de 14 tratamentos. Para a avaliação do objetivo em questão, foram realizadas as seguintes observações, mediante coleta após 90 dias de plantio: número de estacas enraizadas e número de estacas com calos. Através dos resultados obtidos, pode-se concluir que, para obter um maior número de estacas enraizadas, é conveniente o tratamento com NAA à 100 ou 200 ppm mais boro.

Comparison of neutron moisture gauges with nonnuclear methods to measure field soil water status
Provedor de dados: 63
Autores: Kirda,C.; Reichardt,K.
The neutron moisture gauge is compared with the gravimetric-core soil sampling technique, tensiometers and resistance blocks in relation to stability, Held variability, spatial dependence and number of samples needed at a given level of significance. The variance of field water content measurements with neutron moisture gauges is lower than that of the gravimetric sampling, which therefore requires 2 to 6 times as many samples as the number of measuring sites of the gauges to attain the same level of significance. The space dependence of the measurements made with the subsurface gauge varied depending on the average field soil water content. No space dependence was evident when the water content was lower than 0.2 cm³.cm-3 (50% saturation). Measurements...

Efeito da aplicação de efluente da fábrica de celulose junto com fosfogesso na correção da acidez do solo
Provedor de dados: 63
Autores: Kinjo,T.; Silveira,R.I.; Marcos,Z.Z.; Abrahão,I.O.
Foram coletados vários efluentes alcalinos da fábrica de celulose a fim de estudar a utilização destes junto com fosfogesso na correção da acidez do solo. Avaliou-se o poder de neutralização dos efluentes e a lixiviação de sódio na presença de fosfogesso numa coluna de terra. A aplicação do efluente eleva o pH do solo e o volume de efluente necessário para atingir pH 6,5 depende da sua composição química e o poder tampão de acidez do solo. A lixiviação de sódio é maior quando o fosfogesso é incorporado ao solo. A combinação do efluente com o fosfogesso corrige a acidez do solo, aumenta o teor de cálcio e, ao mesmo tempo, reduz o acúmulo de sódio no solo.

Provedor de dados: 63
Autores: Mendes,M.E.G.; Villagra,M.M.; Souza,M.D. de; Bacchi,O.O.S.; Reichardt,K.
Em um estudo das relações hídricas de um seringal de 5 anos de idade, implantado na região sudeste do Brasil em 1984 são mostradas variações de umidade do solo, potencial da água no solo, distribuição radicular, interceptação de precipitação pluvial e escoamento superficial. Resultados indicam a estreita faixa de retenção de água da terra roxa estruturada e a alta correlação entre as variações de potencial da água no solo e a distribuição radicular. O seringal apresentou um sistema radicular com raízes superficiais (0-30cm) se estendendo até a projeção das copas e raízes profundas, atingindo mais de 2,5m. O perfil de solo não apresentou escoamento subsuperficial de água ao longo do declive de 10%, mas apresentou significantes perdas superficiais, chegando...

Efeito de diferentes materiais no pH do solo
Provedor de dados: 63
Autores: Veloso,C.A.C.; Borges,A.L.; Muniz,A.S.; Veigas,I.A. de J.M.
A grande maioria dos solos agrícolas brasileiros apresenta alta acidez (pH H2O &lt; 5,5) sendo um dos principais responsáveis pela baixa produtividade das culturas. Estes solos exigem a aplicação de corretivos para elevar o seu pH, neutralizar os efeitos dos elementos tóxicos, fornecer Ca e Mg como nutrientes e aumentar a produtividade das culturas. Com o objetivo de verificar o efeito de diferentes materiais (calcário calcinado e dolomítico, escória e gesso) no pH do solo, em função da dose aplicada (2, 4 e 6 t/ha) e do tempo de incubação (25, 50 e 75 dias), foi conduzido trabalho em condições de laboratório. Após o período de incubação e determinação do pH em água, concluiu-se que: a) todos os materiais, com exeção do gesso, foram eficientes para elevar...

Detecção de bacteriocinas produzidas por bactérias fitopatogênicas dos gêneros Erwinia, Pseudomonas e Xanthomonas
Provedor de dados: 63
Autores: Biagi,C.M.R. de; Azevedo,J.L. de.
A detecção da produção de bacteriocinas foi estudada em diferentes condições, utilizando-se linhagens de bactérias fitopatogênicas dos gêneros Erwinia, Pseudomonas e Xanthomonas. Obtiveram-se, respectivamente, 58,06%, 71,31% e 40,00% de linhagens produtoras no meio 523, que foi o mais indicado para detecção dessa produção. Uma maior concentração de ágar adicionada ao meio (1,5%) produziu melhores resultados mas, a quantidade de meio nas placas não influenciou a detecção de bacteriocinas. O maior tempo de incubação utilizado (72 h.) facilitou detecção de halos de produção de bacteriocinas. Irradiação com luz ultra-violeta em baixas doses parece facilitar a liberação de bacteriocinas, mas isso varia com a linhagem empregada.

Transmissibilidade do virus do mosaico comum da soja (VMCS) por intermédio das sementes de soja(Glycine max (L.) Merrill)
Provedor de dados: 63
Autores: Barros,A.S.do R.; Silva,W.R. da.
Diante da dispersão do vírus VMCS nas lavouras brasileiras de soja, o presente trabalho foi conduzido procurando verificar a transmissibilidade do patógeno pelas sementes portadoras do sintoma ("mancha café") característico da doença. Para tanto, material proveniente de campos contaminados foi testado quanto às porcentagens de emergência e infecção das plântulas. Os resultados obtidos permitiram concluir que o patógeno é transmitido por sementes, ainda que estas estejam livres de sintomas; contudo, apesar da inexistência de efeitos sobre a emergência, a elevação da freqüência de sementes com "mancha café" tende a ampliar o número de plântulas contaminadas.

Egg length of Anastrepha obliqua Macquart (Diptera, Tephritidae) according to oviposition rate and maternal age
Provedor de dados: 104
Autores: Boleli,Isabel C.; Teles,M. Madalena da Costa.
The length of the entire egg, micropile and vitellus regions of Anastrepha obliqua Macquart, 1835 were measured during all opposition period. Obtained values were compared among them and with oviposition rate. The smallest eggs were produced during the first 35 oviposition days, period where the highest oviposition rate occured. The decrease in egg length was found to be due to a descrease in the vitellus region. Micropile length was found to be pratically constant throughout oviposition. Furthermore, no relationship between maternal age and length was detectable.

The outcome of a wild bee fauna survey in a secondary forest is reported. Sampling was carried out mainly on herbaceous and shrubby vegetation under and at the border of the forest. Results are compared with data collected with the same methodology from a previously surveyed grassland nearby. The secondary forest was richer in Anthophoridae and Apidae species, and less diverse in Megachilidae. Similarity between the two habitats was low. Several unidentified species of Ceratinula, Trichocerapis mirabilis and the stingless bees Melipona bicolor, M. quadrifasciata, M. marginata, Paratrigona subnuda, Scaptotrigona tubiba and S. xanthotricha, are among the species dependent on the forest environment to survive.

The possible dissimilitudes relating to the duration of the egg incubation period and larval stage of Cochliomyia macellaria (Fab., 1775) from offsprings of females from larvae with and without pigmentation on Malpighi tubules, morphotype 1 and 2, respectively, was questioned. The experiment was conducted in climatized chamber regulated at 30ºC, 65±10% RH and 14 hour photophase. No significant difference was observed on average duration of first and second larval instars berween the two morphotypes, taking into account not only the conventional interpretation for the reading of different development phases of the larval stages (morphotype 1:11.0 and 11.9 hours and morphotype 2:11.7 and 12.7 hours for first and second instars, respectively), but also the...

Autores: Branco,Joaquim Olinto; Lunardon,Maria José; Avila,Marcelo Gentil; Miguez,Carlos Fernando.
The C. danae females were collected monthly, within the period of April/91 to March/92. The monthly average variation of the condition factor (Ø1), is associated, among other causes, to both the weight of the gonads (Ø3) and the stomach (Ø2). The difference between Ø1 and Ø3 (ΔØ) estimates the "gonadal condition" showing highest values on the reproductive cycle (May, November, January and March). These months coincide with the highest values of the gonadossomatic index. So can be used as an indicative of the period of spawning of Callinectes danae in Lagoa da Conceição, Santa Catarina, Brazil.

Seventeen clones of Rhopalosiphum padi (Linnaeus, 1758), 14 of R. maidis (Fitch, 1856), and two of R. insertum (Walker, 1849), representing a wide range of host plants and geographic distribution, were examined electrophoretically to determine intra and interspecific variation. Twenty-one enzyme systems were tested using starch-gel techniques. The electromorph variation within species was low, as expected for parthenogenetic organisms. Frequency of heterozygotes was also relatively low for most populations. The percentage of polymorphic loci ranged from 0% to 27.3% in R. padi, but it was lower (0% to 18.2%) in the completely an holocyclic R. maidis. No consistent correlation between band patterns and host plant or geographic origin could be established for...

Studies on the growth of the blue crab C. danae were carried out by the analysis of size-frequency distributions, and the growth curves were determined for both sexes through Bertalanffy equation. 613 males and 511 females were obtained from 10 collecting sites of the lagoon, at night, monthly from January/88 to July/89. The growth curves in carapace width were described according to the following equations: Wid∞ = 14.0 (1-e-0,6975.t) for males and Wid∞ = 13.3 (1-e-0,6555.t) for females. The growth curves in body weigth were also determined, based on the equations of the growth curves and the relationship between body weight and carapace width. The equations are:Wt = 156.9 (1-e-0,6975.t)2.9153 for males, Wt = 134.0(1-e-0.6555.t)2.8994 for females.

Mamíferos descritos na Poranduba maranhense de Frei Francisco dos Prazeres
Provedor de dados: 104
Autores: Avila-Pires,Fernando Dias de.
The contribution of the Franciscan priest Francisco dos Prazeres to our knowledge of the natural history, geography, history and ethnography of Maranhão in the early XIXth Century appeared in the Revista do Instituto Histórico e Geographico do Brazil in 1891. The original manuscript was donated to the Instituto's library in 1843, and disapeared. The printed text was a copy, without the orignal map, donated by Colonel Francisco Manoel da Cunha Júnior. Fray Francisco was a corresponding member, and a better historian and geographer than a zoologist. This paper summarizes the available information on the zoological expeditions that explored Maranhão. A list of all mammals described in the Poranduba Maranhense is provided, followed by the identification of the...

Sobre a provável parafilia de Centrotinae Amyot &amp;amp; Serville (Homoptera, Membracidae)
Provedor de dados: 104
Autores: Creão-Duarte,Antônio José.
An alternative proposition for the analysis of the diagnostic states of the pronotum in the Centrotinae and Membracinae (sensu Strümpel) is presented. In this analysis, a linear transformation series is proposed for this character, departing from the state found in Tolania Stal, 1858 changing to an intermediate state in Centrotinae, which is still treated as plesiomorphic when compared with the one found in Membracinae. The transformation series thus defined, clarifies the problems related to the monophyly of the Membracidae, which is herein supported by the state of pronotum previously used to define the Centrotinae. This later taxon is treated as paraphyletic. The monophyly of the Membracinae is unquestioned, but its sister group is still unknown....

RADIAÇÃO SOLAR TOTAL DENTRO E FORA DE FLORESTA TROPICAL ÚMIDA DE TERRA FIRME (TUCURUÍ, PARÁ)
Provedor de dados: 36
Autores: Januário,Mauro; Viswanadham,Y.; Senna,Renato C.
Medidas de radiação solar global foram executadas dentro e fora de mata tropical úmida de terra firme durante o dia 07 de novembro de 1986, em Tucuruí, Pará. As intensidades de radiação solar incidentes em 3 sensores instalados aleatoriamente no chão da floresta e um sensor localizado em área aberta (sensor padrão) são avaliadas e intercomparadas. A radiação média que atinge o chão da floreeta foi 4.7% da radiação incidente em área aberta adjacente à floresta. As diferenças entre as medidas dos sensores da mata e o padrão pode ser atribuída à distribuição espacial heterogênea da radiação solar que alcança o chão da floresta.

VARIAÇÃO DIMENSIONAL DOS ELEMENTOS XILEMÂTICOS EM DUAS ESPÉCIES MADEIREIRAS DA AMAZÔNIA
Provedor de dados: 36
Autores: Silva,Ademir Castro e.
Árvores de Saccoglotis guianensis Benth e Andira parviflora Ducke com aproximadamente 26 metros de altura foram seccionadas em sete partes para estudo das dimensões de fibras e dos elementos de vasos. No sentido radial ambas espécies mostraram um aumento no comprimento de fibras com algumas irregularidades da medula para o câmbio bem como fibras mais curtas no topo do tronco. Neste existe um maior número de vasos por milímetro quadrado. É discutido a influência de reguladores de crescimento no número de elementos de vasos. Existe uma diminuição no comprimento das fibras e elementos de vasos em direção ao topo depois de terem alcançado valores máximos numa determinada altura, e um decrescimo irregular na largura desses elementos da base para o topo das...

Provedor de dados: 36
Autores: Ferreira,Sidney Alberto do N; Santos,Lenoir Alves dos.
A viabilidade e o vigor das sementes de pupunha (Bactris gasipaesKunth) são assoiados com a perda de umidade das mesmas. Partindo de um teor de umidade inicial de 45%, foi observado que abaixo de 38% de umidade a emergência e o vigor das sementes foram afetados negativamente de maneira significativa. Abaixo de 17% de umidade a emergência foi praticamente nula. Baseando-se nestes resultados pode-se enquadrar as sementes de pupunha dentro do grupo das espécies chamadas recalcitrantes.

Autores: Abreu,Raimunda Liége Souza de.
Estudos sobre a ocorrência das famílias Scolytidae e Platypodidae (Insecta: Co-leoptera) em madeiras verdes são escassos na região amazônica. Estes besouros, apesar de se alimentarem de fungos manchadores, danificam a madeira, construindo galerias para o cultivo do seu alimento e reprodução. Durante a realização de um censo destas famílias em dezesseis essências florestais no município de Presidente Figueiredo - AM, foi observada uma diferença significativa com relação ao número de espécimes coletados, considerando principalmente os gêneros Xyleborus e Platypus, mais comumente encontrados. Foi observada também a susceptibilidade do cerne e alburno das diferentes espécies florestais ao ataque destas famílias, onde constatou-se que o cerne é mais resistente...

Provedor de dados: 36
Autores: Santos,Joselita Maria Mendes dos; Tadei,Wanderli Pedro; Contel,Eucléia P. Β.
Foram estudadas populações de Anopheles triannulatusprocedentes da hidrelétrica de Balbina (AM), quanto ao sistema das esterases, usando-se gel de poliacrilamida e como substrato α-naftil propionato A análise eletroforética possibilitou identificar seis zonas de atividade e o mecanismo de herança foi estudado para cinco locique foram polimórficos. Foram detectados dois alelos para as esterases 1, 2 e 4 e três para as esterases 3 e 5, sendo todos de ação codominante. Os dados de frequências gênicas mostraram-se diferentes para os alelos em cada locus.Os valores de qui-quadrados para as frequências genotípicas evidenciaram que a população não está em equilíbrio para todos os loci,sendo as frequências observadas dos homozigotos superiores as esperadas. Esses...

LAGO AMAZONAS: FACT OR FANCY?
Provedor de dados: 36
Autores: Tuomisto,Hanna; Ruokolainen,Kalle; Salo,Jukka.
It has been suggested that a huge lake, Lago Amazonas, covered a large part of the Amazon basin until as recently as two thousand years ago. According to this hypothesis, the topmost sediments in western Amazonia are almost universally young deposite of lacustrine and deltaic origin. The hypothesis has gained some attention among biologists because of its implications for biological phenomena in Amazonia, especially biogeography and biodiversity. According to the available geological data, however, Amazonia is geologically far more complex than assumed by the lake hypothesis. In the following discussion we will point out the weaknesses of the Lago Amazonas hypothesis, and indicate alternative explanations of the surface geology that are based on...

Autores: Meirelles,Maria Lúcia; Henriques,Raimundo Paulo.
Foi estimada a produção primária liquida aérea de duas áreas de campo sujo de cerrado em Planaltina (DF), sendo uma preservada e outra queimada no inicio do experimento. A produção foi estimada através das diferenças entre o peso seco da fitomassa herbácea aérea coletada quinzenalmente. O estudo foi realizado de outubro de 1980 a abril de 1981, que corresponde ao período das chuvas no DF. A produção primária líquida aérea do estrato herbáceo da área queimada (176 ± 33 g m-2) foi maior que a observada na área que não sofreu queima (108 ± 26 g m-2). A eficiência da conversão de energia solar para matéria seca foi de 0,19 ± 0,04% para a área queimada e 0,12 ± 0,03% na área preservada. A produção quinzenal apresentou correlação significativa com a precipitação...

Autores: Felippe,G. M.; Sassaki,Regina M.; Aveiro,Sílvia M. de Godoy.
Polypodium pleopeltifolium é uma pteridófíta que ocorre, como epífita, em cerrados do Estado de São Paulo. A espécie é fotoblástica positiva, mas alguns esporos germinam no escuro. Tratamento com aplicações curtas a 40 e 5ºC e temperaturas alternadas não aumentou a germinação no escuro. IAA não afetou a germinação, mas a germinação sob luz branca foi inibida por GA3 e ABA. Choques curtos de luz vermelha promoveram a germinação.

Comportamento de regenerantes de Astronium urundeuva (Fr. All.) Engler em área sob ação antrópica
Provedor de dados: 39
Autores: Salomão,Antonieta Nassif; Leite,Angela Maria Conte.
O comportamento de regenerantes de aroeira (Astronium urundeuva) foi observado em área de pastagem. Verificaram-se proporções de 1,7 e 2 cepas para cada plântula. A distribuição desses indivíduos tendeu mais à agregação do que ao acaso. Constatou-se que na área em estudo, a regeneração assexuada; é mais importante para a manutenção da espécie do que a sexuada; provavelmente por haver concorrência entre a pastagem e as plântulas em estágio inicial de estabelecimento. Porém, após seu estabelecimento, as plântulas desenvolvem-se normalmente. Deve-se levar em consideração, tanto as plântulas quanto as cepas ao se definir metodologias de conservação in situ da espécie, visto ser praticamente impossível, hoje em dia, conservá-la isenta da ação antrópica.

Paspalum vaginatum Sw., gramínea perene, estolonífera, com folhas anfistomáticas e pequenas é característica de pântanos salgados, crescendo em condições estressantes na marisma da lagoa dos Patos, molhe oeste da Barra do Rio Grande, RS. Foram feitas contagens mensais de estômatos e micropêlos nas superfícies adaxial e abaxial das lâminas e relacionadas às características abióticas do ambiente. O número de micropêlos da superfície foliar abaxial variou significativamente e diretamente com a temperatura da água intersticial junto às rizosferas. Estes, porém, não mantiveram correlação com a salinidade intersticial. Os resultados sugerem que a espécie seja uma halófita facultativa. O número de estômatos da superfície abaxial manteve um relacionamento inverso...

A estrutura populacional de plântulas da Copaiba, (Copaifera langsdoffii Desf.) foi estudada em mata ciliar do Distrito Federal, no intuito de fornecer subsídios para a conservação in situ da espécie. O método do transecto, tomando em consideração a localização dos parentais (adultos da mesma espécie), foi adotado. Os regenerantes foram plotados e marcados. Considerou-se também a predação e o ataque por patógenos nas plântulas, o que ocorreu da forma intensa e independentemente da proximidade de adultos parentais. A densidade das plântulas nas áreas estudadas foi correlacionada com o aparecimento de clareiras (fator luz). Estimou-se que os regenerantes estudados apresentam idade superior a dois anos, com base no bi ou tri anualidade das árvores no local,...

Foram estabelecidas as distribuições mensais e estacionais do índice de erosão. Os dados mostraram que 62% do potencial de erosão anual ocorre durante dezembro-fevereiro. A freqüência de distribuição dos valores totais anuais e do valor máximo anual do índice de erosão seguiu o tipo de curva inclinada, típica de dados hidrológicos, mas o logaritmo dos dados apresentou distribuição normal. Foi encontrada alta correlação...

Autores: Veiga,Renato Ferraz de Arruda; Corso,Graci Mirian; Curl,Paulo Roberto.
Procurando conhecer a variabilidade dos estômatos ocorrentes nos folíolos do amendoim (Arachis hypogaea L.), cultivares Tatu e SO-909, estudaram-se os tipos de estômatos, o índice estomático e dimensões, com os germoplasmas SO-53 ('Tatu') e SO-909 (PI-259747), obtidos do Banco Ativo de Germoplasma do Instituto Agronômico (IAC). Nas seções paradérmicas dos folíolos, observaram-se quatro tipos básicos de estômatos: anomocítico, anisocítico, diacítico e laterocíclico, além de estômatos geminados. Os laterocíclicos apresentaram-se com maior freqüência. Os diacíticos não são citados na literatura consultada sobre o gênero Arachis. A largura dos estômatos e o índice estomático mostraram diferenças entre os genótipos.

Provedor de dados: 53
Autores: Monteiro,Domingos Antonio.
No período de 1970-1977, estudou-se a produção de sementes verdadeiras de batata-doce (Ipomoea batatas (L.) Lam.), por fecundações artificiais em condições de casa de vegetação, cultivando-se segmentos de ramas com botões florais em vasos com água. Os resultados evidenciaram diferença de comportamento dos genótipos quanto à capacidade de produção de sementes. O genótipo SRT 252 (Rama Grossa) foi o que melhor se comportou como planta feminina, com formação de 57,40% de cápsulas quando cruzado com outros genótipos e 40,20% quando autofecundado.

Autores: Ungaro,Maria Regina Gonçalves; Toledo,Nilva Maria Prestes de; Teixeira,João Paulo Feijão; Suassuna Filho,José.
Progênies e sementes individuais de algumas populações de girassol foram utilizadas em um estudo da adequação da técnica da ressonância magnética nuclear (RMN) para determinação do teor de óleo das sementes. Foram feitas análises de correlação entre essa técnica e o método de extração por "Soxhlet". Os resultados indicaram que o óleo contido nas sementes de girassol comporta-se como líquido na análise pela RMN; o fator geométrico não influiu nas medições pela RMN; houve alta correlação entre os teores de óleo obtidos por "Soxhlet" e pelo método da RMN; os valores obtidos com o uso da RMN foram estatisticamente superiores aos obtidos por "Soxhlet"; não houve correlação significativa entre massa da semente e teor de óleo; houve uma variação de teor de óleo...

Autores: Azzini,Anisio; Zimback,Leo; Carvalho,Cassia R.L.; Costa,Antonio Alberto.
No presente estudo, realizado no Centro Experimental de Campinas (IAC), em 1991, procedeu-se à extração e à caracterização do palmito de cana como alimento humano, determinando-se algumas de suas propriedades químicas. O material genético utilizado foi o clone IAC 70-32, proveniente da Estação Experimental de Piracicaba (SP), do Instituto Agronômico (IAC). O palmito de cana é um subproduto da cultura da cana, com teor de proteína (2,10%) semelhante ao do palmito (Euterpe edulis) (2,18%), podendo ser utilizado como alimento humano. Considerando seu peso médio (8,29 g) e o número de colmos de cana por hectare (60.000), pode-se obter uma produção de palmito de cana da ordem de 483 kg/ha.

El manejo del Espacio en el Imperio Inca es un análisis de la organización del espacio de la ciudad del Cuzco y de la región nuclear Inca. Se trata de un estudio de geografía y de análisis urbano y regional a la vez simbólico y retrospectivo, conducente a la comprensión de un urbanismo histórico específico. Para el desarrollo del trabajo se ha hecho un estudio minucioso de las fuentes coloniales y de las investigaciones contemporáneas, lo que ha conducido a detectar las inexactitudes y contradicciones existentes en esa literatura; así como presentar claramente el estado actual de los conocimientos y formular una propuesta de interpretación del manejo del espacio en la época Inca.

En este trabajo se presenta un balance general de los cambios ocurridos en la economía ecuatoriana en el transcurso de las últimas décadas, a la luz de la política cambiaría. A partir de las diversas tendencias del tipo de cambio se pretende comprobar, en añadidura, los resultados que derivaron de la estrategia de desarrollo disefiada por la CEPAL para América Latina en los años cincuenta. Desde esta perspectiva, probaremos la solidez de una de las políticas macroeconómicas discrecionales que apuntalaban el proceso de industrialización sustitutivo. A ese efecto se analiza el rol de la política cambiaría en ese proceso de "sustitución de importaciones", hasta comienzos de los afios setenta, y del de apertura y "sustitución de exportaciones", de ahí en...

Determinantes de la inversión privada en países subdesarrollados: el caso del Ecuador
Provedor de dados: 122
Autores: Samaniego Ponce, Pablo.
América Latina siguió, hasta mediados de los 70 cuando se empieza a poner en práctica una política económica liberal, un conjunto de propuestas que encontraban con la planificación el camino para el éxito en la gestión del desarrollo. Se estimuló por una serie de mecanismos el fortalecimiento, en unos casos, y el nacimiento, en otros, de actividades consideradas prioritarias y necesarias para alcanzar el desarrollo. Algunas sociedades del subcontinente lograron elevar los niveles de vida, mejorar la distribución del ingreso, mejorar los patrones de vida y, también, se consiguieron algunos procesos, exitosos de crecimiento endógeno basados en el desarrollo tecnológico autónomo.

Crisis y salud en las ciudades (Temas)

Problemas económicos internos y externos han hecho que los recursos financieros del sector público se hayan visto limitados o reducidos. Las políticas de ajuste que se vienen implementando en el Ecuador han permitido cumplir con los acuerdos adquiridos con el Fondo Monetario y el Banco Mundial, profundizando la diferenciación de las características físicas y sociales de las distintas zonas o sectores dentro de cada ciudad, deteriorando cada día más el estado de salud de los sectores populares, afectados por un creciente deterioro de todos los ámbitos del consumo: alimentación, vivienda, recreación, servicios, etc. En los barrios populares de las ciudades ecuatorianas se expresa de manera evidente este cúmulo de contradicciones sociales y económicas; la...

Ajuste estructural y estrategia de desarrollo en el Ecuador de los 90 (Temas)
Provedor de dados: 122
Autores: Borja Cornejo, Diego.
A decir del Presidente Durán Ballén, el objetivo fundamental del programa económico, en el corto plazo, es la reducción de la inflación, con la finalidad de restablecer las condiciones para el crecimiento económico. Extraña forma de empezar a cumplir dicho objetivo cuando con el paquete de medidas se posibilitó un doble ajuste de precios: uno a través de la cadena especulativa originada con los anuncios y amenazas dos semanas antes de las medidas y luego con el propio paquetazo. La táctica de ablandar a la población anunciando "medidas duras" permitió al gobierno generar en el pueblo una actitud de resignación frente al golpe, y al mismo tiempo posibilitó que determinados agentes económicos se resguarden -e incluso lucren- de los efectos ulteriores del...

Restricciones macroeconómicas al crecimiento: simulación de sus efectos a partir de un modelo de tres brechas
Provedor de dados: 122
Autores: Paguay Recalde, Joaquín.
La economía ecuatoriana durante la década de los ochenta, al igual que la mayoría de países de América Latina, se ha caracterizado por la presencia de fuertes distorsiones, tanto internas como externas. En el orden interno una caída persistente de la demanda agregada provocada por una reducción permanente de los salarios reales, hecho que a su vez implicó la reducción de la utilización de la capacidad instalada, desempleo creciente, mayor inflación. De otra parte, la restricción que impuso el servicio de la deuda ha incidido fuertemente en el financiamiento de las actividades productivas. Todo lo anterior ha devenido en una situación de desequilibrio de los principales agregados macroeconómicos.

La formación de recursos humanos en salud frente a la crisis social (Temas)
Provedor de dados: 122
Autores: Barreto, Dimitri.
Existe una estrecha vinculación entre la formación de profesionales de la salud y las prácticas médicas o asistenciales: una y otras están sometidas a determinaciones sociopolíticas, lo que puede dar lugar al aparecimiento de rupturas e incoherencias. A inicios de los 70 se decía que la estructura de los servicios de salud ejerce una acción dominante sobre el proceso de formación de recursos humanos, principalmente a través del mercado de trabajo y de las condiciones que circunscriben esa práctica. Sin embargo, no es posible aceptar una determinación mecánica de la práctica sobre la enseñanza porque la universidad tiene la posibilidad de regular cierta parte de lo que acontece en la vida profesional. Lo que se produce es una interacción recíproca entre la...

Estado, actores y conflicto social en la Amazonía: el caso de Morona Satiago (1940-1992)
Provedor de dados: 122
Autores: Restrepo Guzmán, Marco Tulio.
En los últimos cuarenta años, la Amazonía ha pasado por un acelerado proceso de construcción espacial, el mismo que no es homogéneo, sino que presenta características particulares que lo diferencian internamente. Estas diferencias internas han incidido en la constitución de diversos actores sociales en la región y de la región, en el carácter del conflicto, así como, en el papel del Estado. Sin embargo, poco es lo que se conoce respecto de estos conflictos y de los procesos de constitución de los actores sociales protagónicos a nivel de determinados espacios amazónicos. Por tal razón, la presente investigación tiene como tema central: "Estado, Actores y Conflicto Social en la Amazonía: El caso de Morona Santiago (1940-1992)".

Aunque el trazado ortogonal de la ciudad en base a un casillero de "cuadras" o de manzanas rectangulares, calles rectas perfectamente paralelas y transversales, ya había sido ensayado en la península ibérica en la construcción de aquellos centros urbanos, planificados sin la urgencia de las tierras recién conquistadas a los musulmanes, la...

Un enfoque alternativo en el tratamiento de la inflación: formación sectorial de precios
Provedor de dados: 122
Autores: Rodas Zumba, Sonia.
La crisis económica, política y social que vive la economía latinoamericana ha constituido la preocupación directa o indirecta de muchos trabajos de investigación. El tema que mayores inquietudes y polémicas ha despertado es el tratamiento de la inflación, la explicación de sus causas y de acuerdo con ese diagnóstico, el planteamiento de soluciones o políticas alternativas a las impulsadas en la región. En nuestro país el problema inflacionario cobra interés especial a partir de los primeros años de la década anterior, cuando se registran tasas de crecimiento de los precios cada vez mayores. Se presenta junto con desequilibrios macroeconómicos internos y externos, pero las raíces de este proceso se remontan a períodos anteriores.

El marco jurídico institucional y las empresas estatales fueron los principales instrumentos de intervención estatal.

El Ecuador se está enfrentando a uno de los procesos de cambio más significativo de los últimos años. La globalización de la economía y las modificaciones de la correlación mundial de fuerzas, por un lado, y por otro, las limitaciones estructurales del tipo de industrialización que se ha desarrollado en el país hacen inminente una nueva modalidad de inserción de la economía ecuatoriana al mercado mundial. En ese marco, la integración andina cobra ahora dimensiones distintas a las que dieron lugar a su fundación: es una de las versiones que puede darse al camino hacia la apertura total.

En América Latina, el elevado nivel de desempleo y el permanente deterioro de los salarios, son reconocidos como los principales problemas que se presentan en el funcionamiento del mercado de trabajo.

A lo largo de la década de los ochenta, mucho se ha escrito sobre los efectos que sobre las economías latinoamericanas, en general, y sobre la ecuatoriana, en particular, ha tenido la carga de la deuda externa, hasta el punto de hablarse de la "década perdida para el desarrollo".

Quito.-la ciudad- es mucho más que su mancha urbana,  se ha tomado ya pueblos, valles y montes. Pero no es una sola. En el transcurso del último medio siglo, la fuerza del mercado ha dado forma a una ciudad dual; la planificación no ha querido quedarse atrás y también ha puesto su granito de arena desde el ya legendario «Plan Jones Odriozola». Quito -la cara de Dios- tiene dos rostros: el sur es su lado plebeyo, y aloja a los sectores populares (incluyendo a las clases medias "cholas"); el norte es su faz presentable, y aloja, claro, a los sectores dominantes y las clases medias "blanqueadas".

Quito y Guayaquil comenzaron a marcar siempre el devenir de una nación en constitución como los dos ejes de un territorio en proceso de integración.

Los concejos municipales, donde triunfaron las "huestes de Abdalá", se encuentran preferentemente en las provincias de la costa (Guayas y El Oro), sin dejar de ser importantes algunos concejos municipales chicos de provincias serranas.

La participación de las mujeres en los partidos políticos
Provedor de dados: 122
Autores: Haro P., Nancy.
El presente trabajo, concebido dentro del marco del Curso "MUJER, CAMBIO SOCIAL Y DESARROLLO", impartido por FLACSO -ECUADOR, trata de entender cierto aspecto de la realidad de las mujeres frente al mundo público, vale decir el mundo del poder, monopolizado históricamente por los varones. Una primera parte de este trabajo está compuesta de 2 capítulos (I y II). El primero "Antecedentes histórico - jurídicos", trata sobre el género y la política, raíces de la discriminación de la mujer, sobre el derecho de ciudadanía de la mujer, que es el que le legaliza para participar en la vida política del país, no sólo como población electoral sino, como sujeto de derecho.

El segundo "boom" bananero ecuatoriano
Provedor de dados: 122
Autores: Maiguashca Guevara, Lincon.
Desde el siglo pasado, las relaciones comerciales ecuatorianas con el exterior, se han desarrollado alrededor de un producto agrícola, con una interrupción de 20 años cuando el producto principal fue el petróleo. Primero apareció el cacao que hasta después de la Primera Guerra Mundial fue el único generador de divisas para el país. Luego, y por un largo período, el Ecuador virtualmente desapareció del mercado internacional, hasta que en la década de los años 50 volvió a hacerse presente, esta vez con el banano. En 1973, con el advenimiento de las exportaciones de crudo, por primera vez en la historia del país, un producto agrícola quedó relegado a un segundo plano. A pesar de esto, el Ecuador continuó siendo el mayor exportador de fruta en el mundo.

Ha empezado a calar hondamente la necesidad de reevaluar el fenómeno del caudillismo politico en la historia reciente de América Latina. Tarea esa cada vez más urgente porque como bien sabemos la activación de la estructura caudillista no sólo se reduce a cierta etapa inicial de nuestra azarosa vida republicana que se conoce ya bien como período del desorden, era del caos o tiempo de los cuartelazos sino que sigue proyectándose a las formas actuales de participación política aunque nuestros gobernantes de hoy nieguen ajustarse a tal personalidad autoritaria o porque el régimen emane de un ordenamiento democratico. Una buena parte de las interpretaciones coincide en que el caudillismo aparece fácilmente alli donde el ordenamiento estatal es débil o...

El Frente Amplio y la Intendencia de Montevideo (América Latina)

Autores: Carvajal, Miguel.
Uno de los aspectos destacados en la gestión de las ciudades de Latinoamérica en la última década, es la presencia de gobiernos locales democráticos, y muy articulados a las fuerzas populares, tales son los casos del gobierno de la Izquierda Unida en Lima, del PT en Sao Paulo o del Frente Amplio en Montevideo, para señalar los más significativos. Sus experiencias, los cambios operados en su comprensión sobre las problemáticas urbanas y sus resoluciones, son, sin duda, de una gran ayuda y lección para quienes estamos empeñados en la construcción de realidades nuevas, justas y equilibradas en nuestro continente.Las presentes entrevistas, realizadas a tres funcionarios de dirección de la Intendencia de Montevideo: ARIEL BERGAMINO (Secretario político del...

Los comerciantes piuranos (1700-1830): el soporte humanos de una región económica
Provedor de dados: 122
Autores: Aldana Rivera, Susana.
Las personas viven sus experiencias enmarcadas por su propia cotidianidad y por la del conjunto nacional en la que están inmersos; de allí la importancia y el aporte  de la historia regional: recuperar las variadas perspectivas de vivir, sentir y/o asumir un hecho o una cadena de ellos  que permitan matizar la historia común a todos. En esta línea, el norte es un claro ejemplo de una sociedad a la que el acontecer histórico le ha impreso su sello peculiar. Para caracterizar a los norteños, bastaría señalarlos como comerciantes, reflejando una tradición de larga data que sin perder su originalidad, ha ido asumiendo progresivamente y de acuerdo con la época nuevos patrones de realización mercantil. Durante la colonia, girar en el comercio suponía articularse...

Estado, actores y conflicto social en la Amazonía: el caso de Morona Satiago (1940-1992)
Provedor de dados: 122
Autores: Restrepo Guzmán, Marco Tulio.
En los últimos cuarenta años, la Amazonía ha pasado por un acelerado proceso de construcción espacial, el mismo que no es homogéneo, sino que presenta características particulares que lo diferencian internamente. Estas diferencias internas han incidido en la constitución de diversos actores sociales en la región y de la región, en el carácter del conflicto, así como, en el papel del Estado. Sin embargo, poco es lo que se conoce respecto de estos conflictos y de los procesos de constitución de los actores sociales protagónicos a nivel de determinados espacios amazónicos. Por tal razón, la presente investigación tiene como tema central: "Estado, Actores y Conflicto Social en la Amazonía: El caso de Morona Santiago (1940-1992)".

Provedor de dados: 65
Autores: Luz,Inês Nicoloso Castro da; Corte,Flávio de La; Alda,Joaquin Lopez de; Silva,Carlos Antonio Mondino da.
Cinqüenta e dois produtos Puro Sangue de Corrida (PSC), pertencentes a um estabelecimento localizado no município de São José dos Pinhais (PR), foram utilizados para a determinação de alguns parâmetros fisiológicos. Verificou-se a freqüência cardíaca e respiratória, assim com a temperatura corporal desde a primeira hora após o nascimento até os 180 dias de idade em horários e datas pré-determinadas. As freqüências cardíaca e respiratória decresceram após o sétimo dia de vida e a temperatura corporal oscilou entre 38,2 à 38,8°C. Concluiu-se que através do conhecimento desses valores fisiológicos para cada idade, o médico-veterinário terá bases mais sólidas para uma avaliação diagnostica mais segura.

SEROLOGICAL DIAGNOSIS OF EQUINE INFECTIOUS ANEMIA VÍRUS INFECTION IN THE CENTRAL REGION OF THE RIO GRANDE DO SUL STATE
Provedor de dados: 65
Autores: Rebelatto,Marlon Cezar; Oliveira,Clóvis de; Weiblen,Rudi; Silva,Saul Fontoura da; Oliveira,Luiz Sérgio Segala de.
This paper consists of a brief review on equine Infectious anemia added of the results of serological diagnosis of this infection performed at the Federal University of Santa Maria, RS, Brazil, between 1979 to 1990. A total of 7,035 serum samples were tested by the agar gel immunodiffusion test (Coggins test), to which 40 (0,57%) reacted positively. This percentage of positivity is lower than in other regions of Brazil, probably due to the lack of predisposing factors for equine infectious anemia virus spread, such as, a low density of blood-sucking insects in the South of Brazil and the seldom use of massive therapies and vaccinations in the region.

Autores: Medeiros,Sandro Luis Petter; Santos,Marcos Luis Verdi dos; Bergamaschi,Homero; Berlato,Moacir Antonio.
Em uma cultura de milheto forrageiro (Pennisetum americanum, Leek) cv. pérola, em Eldorado do Sul.RS a 30°05'27"S de latitude, 51°40'18"W de longitude e 40m de altitude, foram quantificados os componentes do balanço de radiação, no ano agrícola de 1988/89. A perda diária de energia por reflexão de ondas curtas foi superior à perda líquida de radiação de ondas longas, porém com valores semelhantes no início da manhã e ao final da tarde. O albedo demonstrou dependência do ângulo zenital da radiação solar, sendo menor próximo ao meio-dia e máximo no início da manhã. O albedo médio diário variou de 0,22 a 0,28, sem relação consistente com o índice de área foliar e com a nebulosidade.

DESORDENS FISIOLÓGICAS EM MACIEIRA INDUZIDAS POR DEFICIÊNCIA DE CÁLCIO E SEU CONTROLE
Provedor de dados: 65
Autores: Brackmann,Auri; Ribeiro,Nerinéia Dalfollo.
Muitas das desordens fisiológicas que afetam os frutos estão relacionadas com baixo conteúdo de cálcio nos tecidos, sendo sua ocorrência diminuída quando há incremento deste nutriente. A deficiência de cálcio em madeira afeta os frutos que apresentam manchas de cortiça próximos a colheita e durante a frigoconservação. Em vista disto, é importante o estudo sobre a absorção, distribuição e funções bioquímicas, bem como a apresentação de alternativas para prevenir ou reduzir desordens fisiológicas causadas por deficiência de cálcio em macieira.

Autores: Rebelatto,Marlon Cezar; Weiblen,Rudi.
O colostro é essencial para a sobrevivência de terneiros. O primeiro leite contém anticorpos específicos os quais detêm a capacidade de fazer frente às principais enfermidades encontradas no meio ambiente. O colostro é muito nutritivo sendo também laxativo. A imunidade da vaca é removida ativamente da corrente circulatória e transferida para o úbere. Da glândula mamaria passa ao trato gastro-intestinal do terneiro pela ingestão e daí é absorvida pela permeabilidade intestinal e pela ausência relativa de enzimas digestivas durante esta fase. Esta revisão trata da importância da imunidade passiva, dos prejuízos econômicos causados pela ausência ou pouca ingestão do colostro bem como dos fatores que interferem nesta absorção. São revisados os principais...

Autores: Manfron,Paulo Augusto; Garcia,Danton Camacho; Andriolo,Jerônimo Luiz.
A cultura da cebola Allium cepa L. ocupa lugar de importância entre as hortaliças cultivadas no Brasil. Em termos de valor da produção, é superada apenas pelo tomate e a batata e, em algumas regiões de São Paulo, Pernambuco, Rio Grande do Sul e Santa Catarina representa a principal atividade econômica. O objetivo do trabalho foi caracterizar aspectos morfo-fisiológicos importantes em cebola que variam conforme as condições climáticas. Apesar de existir um conhecimento satisfatório, o aprimoramento e desenvolvimento tecnológicos são fundamentais para aumentar a produtividade e normalizar o abastecimento do produto.

As alterações hemáticas de 10 cães (7 fêmeas e 3 machos) submetidos a uma sangria controlada, foram observadas durante 28 dias. A sangria correspondeu a remoção de 20ml de sangue por kg. A avaliação laboratorial foi realizada em tempos anteriores e subseqüentes à sangria. Os animais, após a sangria, apresentaram um decréscimo nos parâmetros eritrocitários sendo o ponto mínimo no tempo 5, (72 horas após à sangria) com valores abaixo do normal, o retorno aos valores iniciais ocorreu no tempo 7 (14 dias após a sangria). A porcentagem de reticulócitos refletiu uma estimulação leve da medula óssea que também foi observada pela diminuição da relação M/E que teve o ponto mínimo no tempo 6 (7 dias após a sangria).

Sessenta éguas Puro Sangue de Corrida (PSC) serviram como material para este trabalho. O colostro foi colhido antes do produto mamar e 12 horas após, para se avaliar a cor, a viscosidade, a gravidade específica (GE) e a concentração de imunoglobulinas (Ig) colostrais. Avaliou-se a correlação desses dados com a concentração de Ig sérica dos potrinhos das 3 horas até 7 dias após a primeira mamada. A lactação prematura (LP) influenciou negativamente a concentração de Ig colostral e sérica dos produtos, estando o seu nível sérico de Ig diretamente ligado à quantidade e qualidade de colostro ingerido. A determinação da GE através do colostrômetro foi rápida e precisa. Colostros com GE maior que 1060 possuíam Ig superior a 9,0g/dl e os níveis séricos dos...

EPIDEMIOLOGIA DA LEPTOSPIROSE EM BOVINOS
Provedor de dados: 65
Autores: Brod,Claudiomar Soares; Fehlberg,Marta Fernanda.
A leptospirose é uma zoonose causada por 'ima bactéria que pertence ao gênero Leptospira e a espécie L. interrogans a qual apresenta mais de 200 sorovares diferentes. A principal fonte de infecção desta doença são os roedores peri-domésticos, tais como o rato e o camundongo. Dentre os animais domésticos, os suínos são os principais reservatórios de leptospiras. Esses animais eliminam o agente através da urina, contaminando a água, o solo e os alimentos, principais vias de transmissão da doença. O sêmen de touros infectados também pode transmitir o agente, através da monta natural e da inseminação artificial. A suscetibilidade dos bovinos varia de acordo com alguns fatores, tais como idade, estado fisiológico, utilização e densidade populacional. No...

A MORTALIDADE EMBRIONÁRIA E A EFICÁCIA DA INSEMINAÇÃO ARTIFICIAL EM OVINOS
Provedor de dados: 65
Autores: Moraes,José Carlos Ferrugem.
São apresentados aspectos relativos a ocorrência e a importância da mortalidade embrionária na fertilidade de ovelhas, submetidas a diferentes métodos de reprodução. A análise destes estudos sugere que, embora ocorram maiores taxas de mortalidade embrionária em ovinos quando são adotados métodos artificiais de reprodução, provavelmente, esta não seja a principal causa das insatisfatórias taxas de concepção ao primeiro serviço.

Sessenta potros PSC foram divididos em dois grupos de acordo com a ocorrência de sinais clínicos de doença. Avaliou-se os níveis de Imunoglobulina (Ig) sérica das 3h até o sexto mês de idade. A TSZ pelo espectrofotômetro ou visualmente indicou bem a Ig determinada por eletroforese. A concentração de Ig decresceu no fim do primeiro mês, tanto nos doentes como nos sadios, elevando-se 1 a 2 semanas após. Isso poderia indicar a passagem da imunidade passiva para a própria. A concentração mínima de Ig de 400mg/dl sugerida na literatura não é compatível com a aqui encontrada nos potros sadios; sugere-se estabelecer um novo nível mínimo de Ig de 800mg/dl. Este pode ser considerado a exigência mínima para avaliação de potros de alto risco, no entanto, não deve ser...

ESTUDOS HISTOLÓGICOS EM LINFONODOS DE BOVINOS SOROPOSITIVOS AO VÍRUS DA LEUCOSE BOVINA
Provedor de dados: 65
Autores: Flores,Eduardo Furtado; Graça,Dominguita Lühers; Weiblen,Rudi; Palmeira,André Luiz Bagolin.
Cortes de linfonodos superficiais e ilíacos de 48 vacas soropositivas e 2 soronegativas ao vírus da Leucose Bovina (VLB) foram examinados visando a detecção de possíveis alterações histológicas relacionadas com o linfossarcoma bovino. Trinta animais soropositivos e um soronegativo apresentaram quadros de hiperplasia linfóide (HL), 10 apresentaram linfadenopatia benigna (LB) e 7 animais soropositivos e 1 soronegativo apresentaram hiperplasia linfóide e reticular simultaneamente. Essas alterações possuem caráter benigno e aparentemente não têm relação com a infecção pelo VLB. Nenhum corte evidenciou conclusivamente a existência de lesões neoplásicas. No entanto, linfonodos de 8 animais soropositivos mostraram características histológicas interpretadas como...

DESCRIÇÃO ECOGRÁFICA DO ÚTERO E DOS OVÁRIOS DE ÉGUA VIRGEM DURANTE UM CICLO ESTRAL
Provedor de dados: 65
Autores: Corte,Flavio Desessards De La; Luz,Ines Nicoloso Castro da; Alda,Joaquim Lopes de; Silva,Carlos Antonio Mondino.
Uma égua virgem de três anos de idade teve seu ciclo estral acompanhado diariamente, por exame clínico e ecográfico transretal, para a descrição das modificações estruturais do útero e dos ovários. Concluiu-se que é possível diagnosticar por ecografia a fase do ciclo estral na égua, desde que se leve em consideração o número e tamanho dos folículos, a presença e morfologia de um Corpo luteo (Cl) e as características da parede uterina.

Autores: Girão,Eneide Santiago; Medeiros,Luiz Pinto; Girão,Raimundo Nonato.
Este trabalho objetiva verificar a ocorrência e distribuição estacional de helmintos gastrintestinais parasitas de caprinos durante as estações seca e chuvosa visando o estabelecimento de medidas adequadas para o controle da verminose. O experimento foi conduzido na base física da EMBRAPA/UEPAE de Teresina, no município de Teresina. Em um piquete de Brachiaria humidicola medindo dois hectares, foram colocados oito caprinos machos, entre seis a oito meses de idade. Cinco animais ficaram permanentes no piquete e não receberam tratamento anti-helmíntico durante todo o período (Testemunhas) e três (incorporados ao trabalho a cada mês), após receberem três tratamentos anti-helmínticos, ficaram expostos à infecção helmíntica durante 30 dias no piquete...

OCORRÊNCIA E DURAÇÃO DAS TEMPERATURAS MÍNIMAS DIÁRIAS DO AR PREJUDICIAIS À FECUNDAÇÃO DAS FLORES DO ARROZ EM SANTA MARIA. RS. III: PROBABILIDADES DE OCORRÊNCIA DA DURAÇÃO DAS TEMPERATURAS BAIXAS
Provedor de dados: 65
Autores: Schneider,Flávio Miguel; Buriol,Galileo Adeli; Estefanel,Valduíno.
Utilizando os valores das temperaturas mínimas, máximas e das 21 h, hora local, dos meses de dezembro, janeiro, fevereiro e março registradas na Estação Climatológica Principal de Santa Maria, RS, determinaram-se as probabilidades de ocorrência da duração máxima de horas com temperatura do ar ≤ 10, 11, 12, 13, 14, 15, 16 e 17,0°C e de seqüências de dias consecutivos com no mínimo uma hora de duração com temperatura do ar ≤ 15, 16 e 17,0°C. Essas probabilidades foram obtidas para cada decêndio dos meses estudados. Os resultados evidenciam que o risco de ocorrência de temperaturas prejudiciais à fecundação das flores da cultura do arroz é bem menor no 2° e 3° decêndio do mês de fevereiro. Deve-se, portanto, semear e/ou escolher ciclo de cultivar de arroz que...

Autores: Aude,Maria Isabel da Silva; Marchezan,Enio; Pignataro,lone Aidee Bernardes; Pasqualetto,Antonio.
Foi conduzido um experimento de campo na Universidade Federal de Santa Maria com o objetivo de determinar a época de plantio da cana-de-açúcar (Saccharum sp.) que maximiza a produção de colmos industrializáveis e o teor de sólidos solúveis no caldo (grau Brix). Foram testadas duas cultivares de cana-de-açúcar (NA 56-79 e IAC 50-134) em oito épocas de plantio, de 15 de agosto de 1985 a 15 de março de 1986. Não houve diferença entre a cana plantada em agosto e setembro e nem entre as cultivares. Na colheita da cana-planta a produtividade média foi de 82,5t/ha para estas duas épocas de plantio. A cana plantada em agosto-setembro alcançou altos rendimentos quando a colheita foi realizada aos 12 meses de idade. A cana-de-açúcar plantada em janeiro/1986 e...

EFEITO DO CONTROLE DE DOENÇAS E DE CULTIVARES SOBRE A SANIDADE RADICULAR E A INFECÇÃO ENDOMICORRÍZICA DO TRIGO
Provedor de dados: 65
Autores: Blume,Elena; Fries,Marcos Rubens; Alta,Celso.
Foi conduzido, em Langreder, na Alemanha, um experimento a campo, com o objetivo de avaliar o efeito do controle de doenças da parte aérea e de três cultivares de trigo sobre a sanidade radicular da planta e a infecção com fungos micorrízicos nativos. Os tratamentos constaram de diferentes controles químicos de doenças da parte aérea (sem controle, controle de doenças do colmo, controle de doenças da folha), controle de doenças do colmo e da folha e dos cultivares de trigo Sorbas, Kraka e Kanzler. O comprimento de raízes, o percentual de raízes sadias e a freqüência e intensidade micorrízicas foram avaliados em quatro estádios de desenvolvimento do trigo. Observou-se que o controle químico das doenças provocou, inicialmente, uma inibição no crescimento das...

Provedor de dados: 65
Autores: Cordeiro,João Lari Félix; Neves,Jairo Pereira; Albuquerque,Antonio Jorge Dreon de; Badke,Manoel Renato Teles.
Cem vacas leiteras da região do Vale do Itajaí, de Santa Catarina, foram agrupadas, através do exame ginecológico, em quatro categorias, para um estudo bacteriológico dos catarros genitais inespecíficos. Os grupos compostos de 25 vacas, em fase pós-puerperal, foram assim caracterizados: A - sem alteração; B - catarro genital do primeiro grau; C - catarro genital de segundo grau; D - catarro genital de terceiro grau. O exame bacteriológico das secreções cérvico-uterinas demonstrou que ocorreu crescimento bacteriano em 57 vacas, das quais 46 com manifestação clínica de catarro genital. Os microrganismos mais freqüentemente isolados foram Staphylococcus epidermidis, Streptococcus beta - hemolítico, Bacillus sp., Escherichia coli, Actinomyces pyogenes,...

EFEITOS DA PASTAGEM DE AZEVÉM SOB DOIS PREPAROS DE SOLO, NO DESEMPENHO EM RECRIA E PESO À MONTA DE BORREGAS IDEAL
Provedor de dados: 65
Autores: Vieira,Ademir Martins; Figueiró,Paulo Roberto Pires.
Determinou-se os efeitos do uso da pastagem de azevém (Lolium multiflorum Lam.) sob dois preparos de solo no desempenho em recria e peso à monta de borregas ideal. Utilizou-se borregas com 8 meses e 29,873Kg distribuídas ao acaso nos tratamentos: azevém em preparo convencional de solo (A/C), e azevém em preparo superficial (A/S). Dos parâmetros estudados, a análise de variância mostrou superioridade (P&lt;0,05) de A/C apenas para o ganho de peso. Conclui-se que: 1) a pastagem de azevém em preparo convencional, em relação à mesma no preparo superficial, possibilita, na fase de recria, superioridade no ganho de peso: 2) a pastagem de azevém em ambos os preparos possibilita desempenhos superiores aos observados nas condições tradicionais de produção ovina em...

Autores: Pinto,Marcelo Alves; Gardoso,Ghendy; Marchevisk,Renato Sergio; Silva,Adjelton Soares e.
O conteúdo do presente estudo é resultado da substituição de um terço do comprimento da traqueja de cães, por bioprótese de tecido traqueal homólogo preservado em glutaraldeído tamponado a 2,5%. Quatorze cães sem raça definida, pesando entre 10 e 20kg, receberam os implantes ortotópicos através de anastomose término-terminal, que em seguida foram envelopados com retalho muscular (sternothyroideus e sternohyoideus). Os animais foram acompanhados clinicamente durante o pós-operatório e as biopróteses avaliadas através de exames anatomo-patológicos, radiológicos e endoscópicos, no sétimo, décimo quinto, trigésimo e quadragésimo dia após a implantação.
