Macrobenthos is a good indicator to evaluate the potential effects of human activities on marine benthic ecosystem. In environmental impact assessments (EIAs), macrobenthic species identification typically based morphological characteristics, time-consuming and labor-intensive process for which specific taxonomic knowledge experts are needed. DNA metabarcoding can circumvent most these shortcom...

Four cruises in the Bohai Sea and northern Yellow off Yantai, China, April August of 2020, collected data on species composition community structure characteristics macrobenthos these sea areas. Temporal spatial changes dominant macrobenthic between were also analyzed. The M-AMBI environmental used to assess benthic ecological quality coastal waters Yantai. results revealed differences status t...

Hydrothermal fluids passing through sediments create a habitat hypothesized to influence the community structure of infaunal macrobenthos. Here we characterize the density, biomass, species composition, diversity, distributions, lifestyle, and nutritional sources of macroinfauna in hydrothermal sediments in NE and SW Pacific settings, and draw comparisons in search of faunal attributes characte...

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...

The large-scale conversion of natural mangroves to aquaculture reduces species richness and diversity. Large areas abandoned ponds in where formerly predominated China southeast Asia represent important potential effective targets for mangrove restoration. Here, we empirically assessed the α-diversity (species richness) β-diversity (variation community composition) mangrove, macrobenthos, fish ...

Abstract Taka Bonerate waters are the third largest atolls in world, rich marine biodiversity, natural structures and aesthetics. Seagrass beds these grow well on small islands, one of coastal ecosystems that support biodiversity have many benefits for humans economic, social cultural aspects. This study aimed to examine diversity, distribution, abundance macrobenthos several islands National P...
