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...

Pollution associated with marine debris is of global ecological concern, as it threatens wildlife and local economies. Submerged alters benthic species composition community characteristics. The study site Jaguri, Jeju Island, where a variety submerged was found, used to investigate the impact on macrobenthic fauna sandy rocky substrates. dominant macrobenthos taxon differed by sediment type; p...

The impact of pesticides on macrobenthos communities was studied on two aquatic environments in Northern Italy; River Meolo, a site exposed to agricultural pollution, and River Upper Livenza a low pollution reference site. Colonisation of artificial substrates was compared throughout the productive season. The relevance of multiple environmental stressors other than pesticides (e.g. oxygen depl...

Knowledge about community structure and genetic diversity can help assess the potential for change in loss restoration of biodiversity, thereby facilitating effective management ecosystem protection. Macroinvertebrate communities are an important biotic component deep sea cold seep ecosystems. As Haima is increasingly being assessed its gas hydrate mineral wealth, knowledge characteristics macr...

During the Persian Gulf and Oman Sea Oceanographic study (PG-GOOS) in autumn 2012, sampling of macrobenthos was undertaken in 31 stations in Hormozgan Province waters. Three samples were taken from each site using Van Veen grab. Effects of environmental variables on assemblages and distributions of macrobenthos were analyzed. A total of 5677 individuals of macrobenthos were counted being repres...

The ecotoxicological effects of oil spill from the grounded vessel MV River Princess on the intertidal benthic organisms of Sinquerim-Candolim beach at Goa were investigated. An intertidal expanse of 1 km on either side of the grounded vessel was selected to evaluate the concentration of total petroleum hydrocarbon (TPH) in the sediment and its effects on the composition, abundance and diversit...

This study examines whether or not biogeographical and/or managerial divisions across the European seas can be validated using soft-bottom macrobenthic community data. The faunal groups used were: all macrobenthos groups, polychaetes, molluscs, crustaceans, echinoderms, sipunculans and the last 5 groups combined. In order to test the discriminating power of these groups, 3 criteria were used: (...
