Concentrations of PAHs (polycyclic aromatic hydrocarbons) in various marine organisms in relation to those in sediments and to trophic level
TLDR
The PAH concentrations determined in the organisms were significantly negatively correlated with logKow values, but to different extents according to the species, explained by the greater exposure of the organisms to the lower molecular weight compounds. Expand
The amphipod Corophium multisetosum (Corophiidae) in Ria de Aveiro (NW Portugal). I. Life history and aspects of reproductive biology
TLDR
The life-history pattern and reproductive features of C. multisetosum in Areão are closely related to temperature and salinity; other environmental conditions such as oxygen content of the water and food availability may also be relevant. Expand
Spatial and seasonal changes of brackish peracaridan assemblages and their relation to some environmental variables in two tidal channels of the Ria de Aveiro (NW Portugal)
TLDR
The shallow-water fauna of 2 main channels in the Ria de Aveiro was sampled between June 1995 and June 1996 using a suprabenthic sled, providing an invaluable example for field studies and showing significant differences between the 2 channels. Expand
Biodiversity and structure of the suprabenthic assemblages from South Shetland Islands and Bransfield Strait, Southern Ocean
TLDR
Four suprabenthic assemblages were discriminated in the study area, apparently more structured by the degree of shelter-exposure and development of sessile epifauna than by water depth or sediment features. Expand
Spatial distribution of deep-sea decapods and euphausiids near the bottom in the northwestern Mediterranean
TLDR
The presence of large individuals of mesopelagic species near the sea floor is ascribed to onto­ genetic migrations, which indicate differences between population structure of mesOPelagic spe­ cies near the bottom and in the midwater. Expand
Comparing production-biomass ratios of benthos and suprabenthos in macrofaunal marine crustaceans
TLDR
The high P/Bs reported for suprabenthic species indicate how a nontrivial part of benthic produc - tion can be ignored if suPRabenthos is not well sampled, therefore biasing the models of energy flow generated for trophic webs. Expand
Suprabenthic assemblages from South Shetland Islands and Bransfield Strait (Antarctica): preliminary observations on faunistical composition, bathymetric and near-bottom distribution
TLDR
Data is presented on the occurrence and relative abundance of the main suprabenthic groups collected in the water layer immediately adjacent to the bottom (10–140 cm above bottom) and the distribution and spatial separation in the main groups are discussed. Expand
On the structure of the neritic suprabenthic communities from the Portuguese continental margin
TLDR
Multivanate analysis showed that differences in faunal composition between the 2 geographic areas were smaller than depth-related vanahons within geographic areas. Expand
Cumaceans (Crustacea) from the Bellingshausen Sea and off the western Antarctic Peninsula: a deep-water link with fauna of the surrounding oceans
TLDR
The presence in the deepest sampling sites of species shared with faunas of surrounding oceans suggests a link between these faunaas and those of deep Antarctic waters. Expand
Diel vertical migrations and feeding behavior of the mysid Rhopalophthalmus africana (Crustacea: Mysidacea) in a tropical lagoon (Ebrié, Côte d'Ivoire)
TLDR
Nocturnal increase in gut fullness suggests night-time feeding, but relatively high gut fluorescence during the day, resulting mainly from a fluorimetric tracing of animal prey, suggested also a diurnal ingestion of zooplankton items concentrated near the bottom. Expand
