Work was undertaken to formulate a practical methodology enabling the evaluation of benthic resources along the coast of Argentina. Location and numbers of Chlamys tehuelcha, principal seafood resource of the area, was an obvious starting point. Includes species lists. Centro Nacional Patagdnico. Puerto Madryn, Pcia.

properties of marine sediments and the vertical distribution of the microfauna. Vie Milieu, Suppl. 22:509-52 I.

Processes which affect the vertical distribution of oxidized and reduced compounds in marine near- surface sediments were studied and their importance for the microfauna (e.g., vertical zonation, trophic significance) was assessed. A redox discontinuity layer in sandy, shallow-water sediment and the factors (organic content, oxygen, light) influencing this layer are discussed. Correlation of microfaunal vertical distribution with the redox profile is explained by three factors: feeding on prey relegated to specific redox conditions, anaerobic tolerance, and tolerance to toxic, reduced compounds (e.g., H2S).

Texas seagrass meadows: ~laC evidence for the importance of benthic plants. Estuar. coast, mar Sci., 8(6): 499-509.

Fish and shrimp collected in seagrass beds in estuarine and nearshore areas were enriched in t:~C by 3.3 to 5.1"/oo relative to comparable animals collected offshore, suggesting that the animals fed on the relatively 13C-rich benthic plants. Polychaete worms (Diopatra cuprea) collected in seagrass beds were as much as 8.3%0 enriched in t:~C. Includes species lists.

The autoecology of about 200 species is investigated on the basis of approximately 3000 dredge samples. Endofauna are classified into infralittoral, coastal circalittoral and offshore circalittoral categories which differ in terms of edaphic, climatic and thermal factors. The present study prepares the way for synecological investigations. Laboratoire de Zoologic, Facult6 des Sciences, 29 N, Brest, France. (rio)
