Benthic invertebrates are a well-established target in environmental quality status evaluations. The AMBI (AZTI's Marine Biotic Index) was developed to determine the impacts and the quality status of soft-bottom marine benthic communities. The aim of this study was investigating multivariate pattern of benthic invertebrate community and application of AMBI (AZTI's Marine Biotic Index) for dete...

Associations between macrobenthic communities, measures of water column and sediment exposure, and measures of anthropogenic activities throughout the watershed were examined for the Chesapeake Bay, U.S. The condition of the macrobenthic communities was indicated by a multimetric benthic index of biotic integrity (B-IBI) that compares deviation of community metrics from values at reference site...

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...

Submarine mud volcanism represents an important pathway for methane from deeper reservoirs to the surface, where it enters the benthic carbon cycle. To quantify overall methane release from the Captain Arutyunov mud volcano (CAMV) and to assess the contribution of macrobenthic seep organisms to the regulation of the benthic methane flux, we linked water column methane concentrations, seabed met...

A traditional taxonomic approach coupled to a biological traits analysis was conducted in order provide new insight into macrobenthic communities associated with subtidal sandy environments. Results suggest that the macro-scale distribution of benthic is mainly driven by migration rate bedforms (sandbank, barchan dune and transversal dune) which changes sediment grain size reduces diversity. cl...

Similar environmental driving forces can produce similarity among geographically distant ecosystems. Coastal oceanic upwelling, for example, has been associated with elevated biomass and abundance patterns of certain functional groups, e.g., corticated macroalgae. In the upwelling system of Northern Chile, we examined measures of intertidal macrobenthic composition, structure and trophic ecolog...
