Settlement of an unidentified oyster (Crassostrea) and other epibenthos on plastic substrates at a northern Brazilian mangrove island.
However, bottom trawl surveys cannot be used in areas that are too steep or rocky, have fragile epibenthos, such as coral, or are legally closed to trawling.
targeted primarily juvenile fishes and motile crustaceans with their seine samples, whereas this study used fyke net arrays targeting adult fishes, suction sampling of epibenthos, and core sampling of infaunal macrobenthos.
Southeastern Chukchi Sea (Alaska) epibenthos. Polar Biology 28(5):402-421.
The aim of the survey was to document the epibenthos in the Big Russel to provide a baseline of species composition in an area where tidal development may occur, and to identify suitable control areas for any future tidal development impact assessments.
Increases in the severity and extent of hypoxia could result in altered biogeochemical processes in the hypolimnion and in the epibenthos. Increased use of available electron donors could lead to a reduced redox potential earlier in the summer.
It is an effective tool for mapping shallow benthic habitats, monitoring seagrass beds, and characterizing the ecological condition of the epibenthos. By combining aerial imaging with diver- and boat-based observations, comprehensive databases can be generated from estuary-wide surveys of submerged aquatic vegetation, including measurements of seagrass cover in space and time, macroalgal abundance, and shifts in epibiotic inhabitants.
The proposed ecosystem would have been inhabited by deposit-feeding epibenthos (producing Rusophycus and rare Cruziana) and interface burrowers (Helminthopsis); plug-shaped burrows in TF25b are likely a preservational variant of Rusophycus.
