Nematodes occur regularly in macrobenthic samples but are rarely identified from them and are thus considered exclusively a part of the meiobenthos. Our study compares the generic composition of nematode communities and their individual body weight trends with water depth in macrobenthic (>250/300 µm) samples from the deep Arctic (Canada Basin), Gulf of Mexico (GOM) and the Bermuda slope with m...

Biological response and ecological indices of benthic communities, such as greater mortality of foraminifera and shell abnormalities, have been used to document pollution effects on ecosystems. Shadegan Wetland was damaged from a deposition of huge amounts of soot and products of burning oilwells of Kuwait as well as chronic exhaust fumes of refinery and industrial furnaces. In this investigati...

Mangroves are critically threatened by human activities, despite the important ecosystem functions and services they provide. Mangroves in Cameroon represent no exception to the worldwide trend of mangrove destruction, especially around Douala, on the Wouri river estuary. In two sites around Douala, we assessed the presence of sterols, PAHs, PCBs, DEHP, DDT and its metabolite p,p'-DDE and poten...

Water quality in Hangzhou Bay is inferior (grade 5) because of discharged from Yangtze River and Qiantang River, factories around the bay. This study analyzed relationships between environment macrobenthic communities at 44 stations throughout Bay, based on samples collected 2006, 2016–2018, 2021. Long-term spatial temporal changed macrobenthos, influence secondary water fronts community compos...

Macrobenthos play an important role in global biogeochemical cycles and carbon energy exchange. Macrobenthic communities on continental shelves are alimented through the sedimentation of organic material. Sedimentary is key step for cycling within shelf benthic trophic web. However, quantitative relationship between macrobenthos sediments based total (TOC), pathways applied by stable nitrogen i...

Bottom trawling causes physical disturbance to sediments particularly in shelf areas. The disturbance due to trawling is most significant in deeper areas with softer sediments where levels of natural disturbance due to wave and tidal action are low. In heavily fished areas, trawls may impact the same area of seabed more than four times per year. A single pass of a beam trawl, the heaviest gear ...

The influence of the ENSO cycle on marine fauna and flora has only recently been given the attention it deserves. The very strong 1997–1998 El Niño and its obvious effects on marine biota was a key point in ENSO research, but unfortunately few quantitative data about the 1997–1998 El Niño itself are available. To gather information about the effect of ENSO on the macrobenthos, we performed a bi...
