Alimentação do mapará (Hypophthalmus edentatus Spix, 1829) do lago do Castanho, Amazonas (Siluriformes, Hypophthalmidae) () Acta Amazonica
Carvalho,F. Martinho.
Resumo Foram feitas análises do conteúdo estomacal e observações de estruturas do trato digestivo e dos rastros de Hypophihalmus edentatus, com o objetivo de determinar-se o regime alimentar e as possíveis adaptações morfológicas relacionadas a este regime. Os resultados obtidos indicam que a espécie é pelágica zooplanctófaga e seletiva para os maiores componentes do zooplancton. Verificou-se que o número de rastros aumenta com o crescimento mas o espaço entre eles permanece praticamente constante.

Alpheus saxidomus new species, a rock boring snapping shrimp from the Pacific coast of, Costa Rica, with notes on Alpheus simus Guérin-Méneville, 1856 Naturalis
Holthuis, L.B..
Recently, Professor Dr. Rudolf Fischer, Institut für Geologie und Paläontologie, Philipps-Universität, Marburg, F. R. Germany, submitted for identification some material of an Alpheid shrimp, which was found to be responsible for a considerable erosion of part of a rocky shore on the Pacific coast of Costa Rica. The species proved to be new to science, while also the rock-boring activities seem hitherto to be unknown for the Alpheidae, or, for that matter, for Decapod Crustacea as a whole. The new species proves to be closely related to Alpheus simus Guérin-Méneville from the Caribbean area, but it shows minor, but evidently constant differences. It is a great pleasure to thank Professor Fischer for his kindness in allowing me to study this material and...

ALTERNATIVE PARAMETER SPECIFICATION IN E, V ANALYSIS: IMPLICATIONS FOR FARM LEVEL DECISION MAKING AgEcon
Adams, Richard M.; Menkhaus, Dale J.; Woolery, Bruce A..
This study compares the structure of E, V frontiers under several specifications of expected income and variance parameters with emphasis on fundamental differences in efficient crop mixes. The results are generated using data from a specific production region and a selected set of cropping activities for Wyoming. The risk-efficient frontiers and underlying crop mixes display sensitivity to alternative parameter definitions and suggest that if researchers intend to use the E, V approach in providing decision information to producers, care should be exercised in the choice of income and risk measures.

Alvinella pompejana gen. sp. nov., Ampharetidae aberrant des sources hydrothermales de la ride Est-Pacifique ArchiMer
Desbruyeres, Daniel; Laubier, Lucien.
Several unknown animal forms have recently been collected in the immediate vicinity of hot hydrothermal vents in the Eastern Pacific Ocean, forming a flourishing community of organisms. A tubicolous polychaete builds parchment like tubes around some of the hydrothermal vents. The tubes are covered with particles of metallic sulfur. This annelid is a new species, and is called Alvinella pompejana, new genus and species. The new sub-family Alvinellinae, erected to contain this new species, can be included in the family Ampharetidae (order Terebellida), in spite of several aberrant features. In addition to its morphological and taxonomic peculiarities. Alvinella pompejana also exhibits some remarkable biological features, in particular the existence of two...

AMOCO CADIZ : Conséquences d’une pollution accidentelle par les hydrocarbures – Fates and effects of the oil spill. Analyse bibliographique ArchiMer
CNEXO; Ministère de l’Environnement et du Cadre de Vie.
Il nous a paru indispensable, après la catastrophe de l'Amoco Cadiz, de suivre les publications parues sur le sujet: articles ou communications scientifiques sur l'impact écologique, rapports sur la lutte contre la pollution, textes et mises au point juridiques ou encore bilans économiques ... Le colloque qui se déroule au Centre Océanologique de Bretagne, du 19 au 22 novembre, est une occasion de publier la dernière mise à jour du dossier, au moment où cette réunion viendra en grossir tout d'un coup le volume.

Amphibian distribution patterns in western Europe Naturalis
Zuiderwijk, Annie.
Mechanisms controlling the distribution of amphibians in western Europe have been studied in France where related species, isolated from each other at least during the last glacial period, are now sympatric. Occurrences and biotope preferences of the various species were investigated in several regions, with attention to the position of each region within the ranges of the species: central or peripheral. For some species the previously known distribution boundary is partially precised. The population densities of related species in their zones of overlap are discussed. Three pairs of species are considered in particular. Triturus helveticus and T. vulgaris have a large sympatric area in which they appear to be gradually replacing one another. Competition...

Amsterdam Expeditions to the West Indian Islands. Report 69. Station list 1980 Naturalis
Stock, J.H..
In 1980 members of the Institute of Taxonomic Zoology (Zoölogisch Museum) of the University of Amsterdam, have sampled the stygofauna fauna of a number of West Indian islands. The present report records the stations in which stygobionts (= groundwater organisms) were collected. The main purpose of the program was to test the value of various biogeographic models for explaining the insular fauna.

Amsterdam Expeditions to the West Indian Islands, Report 8. A new cave amphipod (Crustacea) from Curacçao: Psammogammarus Caesicolus n. sp Naturalis
Stock, Jan H..
A new species of Amphipoda, Psammogammarus caesicolus, is described from interstitial, anchihaline waters in Blauwbaai cave, Curaçao, Netherlands Antilles. By the morphology of the third uropod, the new species links the somewhat aberrant Ps. longiramus from the Red Sea with the type-species of the genus, Ps. coecus, from the Mediterranean. The classification of the Eriopisa complex, to which Psammogammarus belongs, is reviewed, resulting in a stricter delimitation of, presumably monophyletic, genera, and the creation of three new genera: Madapisella (type-species Eriopisa madagascarensis Ledoyer, 1968), Nippopisella (type-species Eriopisella nagatai Gurjanova, 1965), and Tunisopisa (type-species Eriopisa seurati Gauthier, 1936). The distribution of the...
