The Ulleung Basin of the East Sea is a biological hotspot, but studies on macrobenthos therein are lacking. To evaluate species diversity and community structure in Basin, we conducted survey from 2017 to 2021. A total 262 was detected by survey, average habitat density 243 individuals/m2. biomass 43.7 g/m2, Shannon Wiener’s index 2.3 (0.69–3.61). dominant were polychaetes Terebellides horikosh...

The availability of benthic O2 plays a crucial role in benthic microbial communities and regulates many important biogeochemical processes. Burrowing activities of macrobenthos in the sediment significantly affect O2 distribution and its spatial and temporal dynamics in burrows, followed by alterations of sediment microbiology. Consequently, numerous research groups have investigated O2 dynamic...

Spatial patterns of 5 components of the macrobenthos [corals, macroalgae, mollusks, sponges, and echinoderms) at 42 stations on 4 reef types were compared in Moorea Fifteen a b ~ o t ~ c and biotic factors were measured and included in Canonical Correspondence Analyses. Macrobenthic communities were dominated by corals and macroalgae. Two major gradients (along the bays, and from the fringing r...

To obtain updated, more accurate estimates of macroinvertebrate standing stocks in Lake Michigan, benthic biomass (ash-free dry weight) was determined at 40 stations in the southern end of the lake in 1980 and 1981. Biomass generally increased as sampling depth increased from 16 to 30 m, peaked at depths of 30-40 m, and then declined at depths greater than 40 m. Mean total biomass at the 16-30 ...

This study evaluated pollution levels in water and sediments of Península de Paraguaná and related these levels with benthic macrofauna along a coastal area where the largest Venezuelan oil refineries have operated over the past 60 years. For this, the concentration of heavy metals, of hydrocarbon compounds and the community structure of the macrobenthos were examined at 20 sites distributed al...
