The aim of this work was to determine the impact sympagic (ice-associated) algal primary production on quality Arctic filter-feeding bivalves. For purpose, we investigated sea ice lipids (including omega-3 polyunsaturated fatty acids (n-3 PUFA) and highly branched isoprenoids (HBI)), as well their subsequent incorporation into truncate softshell clam (Mya truncata) Greenland cockle (Serripes gr...

Seamounts and oceanic islands rise from the seafloor provide suitable habitat for a diverse range of biological assemblages including Vulnerable Marine Ecosystems (VMEs). Whilst they have been focus some work globally, there has little description physical environments seamounts in South Atlantic Ocean. In this study, we characterized benthic assemblage composition 13 spanning 8–40°S within exc...

Benthic diatoms are widely used in Europe and worldwide to access ecological status of running waters. One of key goals of Water Framework Directive is to classify rivers and streams using biological quality elements and type specifi c reference conditions. According to system B which incorporates additional abiotic descriptors, there are 24 water types in Croatia. For biological analyses 92 ri...

Mumbai, a megacity of India, and its adjacent marine environment, though heavily stressed from various anthropogenic interferences, harbor approximatley 146 km(2) of mangrove cover. Manori creek, in the close vicinity of Mumbai, sustains relatively better mangrove formations. A creek habitat had been evaluated for its biological and environmental characteristics, and is compared with similar bu...

The discovery that foraminifera are able to use nitrate instead of oxygen as an electron acceptor for respiration has challenged our understanding of nitrogen cycling in the ocean. It was thought before that only prokaryotes and some fungi are able to denitrify. Rate estimates of foraminiferal denitrification have been very sparse and limited to specific regions in the oceans, not comparing sta...

Studies referring the amphipod diversity have been mainly focused on benthic environment. This study aimed to analye epipelagic fauna composition in a sector of southern Gulf Mexico (GoM). Previous records comprised oceanic province; our dataset included both and neritic zones, off several fluvial lagoon systems. The biological material 485 data total abundance 3,802 individuals. Surveys were c...
