Effects of anthropogenic disturbances of tropical soft-bottom benthic communities

Taxonomic level for assessing oil spill effects on soft-bottom sublittoral benthic communities.

Infralittoral soft-bottom macrofauna abundance data collected during four-year surveys after the Aegean Sea (Galicia, Spain) and the Amoco Cadiz oil spill (Brittany, France) at a total of seven sites were analysed at three different taxonomic levels (species, genus, and family). The effects of the spills on macrofauna populations were very similar in the two areas. The post-spill time-courses o...

Sponge-mediated nitrification in tropical benthic communities

We examined changes In the levels of dissolved inorganic nitrogen (DIN) during incubation experiments with 4 conspicuous sponge species from Caribbean coral reefs, mangroves, or seagrass beds (Chondrilla nucula, ?Pseudaxinella zeai, Oligoceras violacea, Plakortis halichondroides). DIN accumulation in the incubation water was detected for all the species, but no significant DIN concentration cha...

Assessing benthic health of hard substratum macrobenthic community using soft bottom indicators and their relationship with environmental condition

This study aimed to assess ecological quality status of hard substratum macroinvertebrates communities of the Caspian Sea with three ecological indices and their relation with environmental factors. For this purpose benthic communities of the Caspian Sea basin were studied seasonally during 2014 in 8 sampling sites. Temperature, salinity, dissolved oxygen, pH, nitrate, nitrite, silicate and pho...
