| Les objectifs pour l'année 1996 étaient les suivants: Poursuivre les premières reproductions des espèces pour lesquelles nous disposons de géniteurs GO. L'objectif est toujours de limiter le stockage d'animaux importés en produisant une descendance simultanément à des témoins C. gigas qui serviront de comparaison. Tenter des hybridations inter-spécifiques des différents taxons présents au sein du conservatoire en fonction des connaissances disponibles dans la littérature sur ce sujet (voir pour revue Gaffney et Allen, 1993). • Importer de nouvelles souches ou espèces. Élargir la gamme des espèces présentes au sein du conservatoire de souches (les capacités d'accueil de la salle de quarantaine étant Limitée). |

| This study revisits the consistent aggregation (over households) property of almost ideal demand system (AIDS) models and presents a method to explicitly account for expenditure aggregation bias when estimating the aggregate AIDS model with time-series data. Ignoring aggregation bias can lead to biased and inconsistent parameter estimates and can cause aggregate demand functions to be inconsistent with the demand functions at the individual household level. Recognizing the general limited information contained in aggregate time-series data for explicitly modeling aggregation bias, we present a new method of constructing an aggregation bias term that is derived from the proportions of household in different income groups. This information is generally... |

| In a previous paper (H.J. Nelis, P. Léger, P. Sorgeloos, and A.P. De Leenheer, Antimicrob. Agents Chemother. 35:2486-2489, 1991) it was reported that two selected antibacterial agents, i.e. trimethoprim and sulfamethoxazole, can be efficiently bioencapsulated in nauplii of the brine shrimp <i><i>Artemia</i> franciscana</i> for administration to fish. This follow-up study showed that larvae of the sea bass and the turbot as well as postlarvae of the white shrimp accumulate the therapeutic agents in high quantities when fed medicated <i>A. franciscana</i>. To monitor their levels as a function of time, the liquid chromatographic method originally developed for the analysis of <i>A. franciscana</i> was modified... |

| Eight acoustic surveys were carried our in the Bay of Biscay, during 1989-94, to study the distribution and abundance of anchovy (Engraulis encrasicolus, L.) in that area. Acoustic data were stored using the INES/MOVIES acquisition and processing system. Species-specific distribution patterns were confirmed through complementary sampling with a mid-water trawl. This paper summarises the combination of technical procedures used for acoustic assessments, and the results of acoustic surveys in the Bay of Biscay that pertain to the dynamics of this stock. Information is presented on the distribution and abundance of anchovy and co-occuring species, and on the movement patterns detected within the pelagic fish community, in relation to environmental conditions.... |

| Wheat, barely, flaxseed, and oilseed sunflower acreage respond to different economic variables. Wheat and barely acreage must be divided among program-complying, program-planted, and nonprogram-planted acreage because these categories respond to different variables and respond to own expected-revenue and price-risk variables in opposite ways. Flaxseed, sunflower, and nonprogram-planted acreage of wheat and barley have highly significant, positive responses to their own expected revenue and negative responses to their own-price risk. Flaxseed and sunflower acreage have been more responsive to their lagged values than to expected revenues for wheat. |

| O experimento objetivou determinar a taxa de acúmulo de matéria seca e a duração do período de enchimento de grãos do triticale em Santa Maria - RS. Foram avaliadas cinco cultivares (BR I, BR 2, CEP 15, CEP 18 e IAPAR 23) no delineamento experimental em blocos ao acaso, nos anos de 1988 e 1989. A duração do período da antese à maturidade fisiológica foi de 45 dias, enquanto que o ciclo, da semeadura à maturidade fisiológica, foi de 156 dias, correspondendo a 676 e 1637 graus dias acumulados, respectivamente. A taxa de acúmulo de matéria seca nos grãos foi em média 0,694mg/dia e o peso médio de grão, estimado na maturidade fisiológica foi de 31,3mg. As cultivares estudadas de triticale apresentam diferentes taxas de acúmulo de matéria seca, o que permite o... |

| Avaliou-se, em campo naturalmente infestado, a adaptação hospedeira das variedades de abacaxi Smooth Cayenne, Abacaxi-de-gomo, Bico-de-rosa, Boituva, Guiana, Huitota, Manzana, Natal Queen, Pérola, Perolera, Rondon, Roxo-de-Tefé e Turi Verde a Meloidogyne incognita raça 1. Somente 'Huitota' apresentou populações do nematóide significativamente menores que aquelas encontradas na 'Smooth Cayenne', considerada boa hospedeira da espécie. |
