In soft sediments, ecosystem engineers (EEs) may play key roles in modifying habitats and therefore affecting bottom-assemblage species. In the southwestern Atlantic mud flats, 2 EEs coexist: the stout razor clam Tagelus ...

Polychaetes and burrowing crabs are widely distributed in intertidal soft bottom environments, playing an important role in structuring infaunal assemblages through trophic and non-trophic interactions such as bioturbation. ...

The spatial and temporal differences in the structure and composition of benthic invertebrates were studied at three sites of the Samborombón River, which is an important tributary of the Río de la Plata Estuary (Argentina), ...

This study evaluates encrustation and bioerosion of brachiopods (Bouchardia rosea) and bivalves (Semele casali) occurring on the inner shelf of the Southeast Brazilian Bight, accounting for differences in water depth, ...

The basal portion of the Permian Rio do Rasto Formation (Serrinha Member), Passa Dois Group, Parana Basin, Brazil, records an entirely new bivalve fauna intercalated between the underlying Pinzonella neotropica assemblage ...

Permian bivalves of the Parana Basin evolved in a large inland sea, under conditions of extreme isolation and environmental stress. Although known since 1918, its evolutionary history is still obscure due to the incomplete ...

Biofacies and taphonomic analysis has allowed for the reconstruction of the paleoenvironmental history of accumulation of a series of spectacular mollusk-dominated shell-concentrations from the Puerto Madryn Formation and ...

Deep sea benthic foraminifera of the Panama basin: ecology and their possible relation with deep sea currents. The relationship between recent benthic foraminifera and bottom currents in the Panama basin (Colombian Pacific) ...
