SUMMARY: Polychaete assemblages were studied from samples taken in the Southwestern Atlantic, between 34°S and 38°S (Argentinean Biogeographical Province) during 1993, 2001 and 2002 from a series of oceanographic cruises in mixohaline to oceanic waters. Polychaetes represented almost 25% (number of taxa) of the macrobenthic assemblages; 57 taxa corresponding to 29 families were identified. The MDS plot shows an ordination of samples according to the following areas: the central estuary and mouth of Río de la Plata (group 1), the coastal shelves of Uruguay and Argentina and the transect off the mouth of Río de la Plata (groups 2 and 3) and other coastal stations from both countries (groups 4 and 5). The abiotic variable that best explained the distribution pattern (BIO-ENV analysis) was the bottom salinity, while the best combination included 2 variables: bottom salinity and type of bottom. Trophic diversity increased with salinity. The distributional range of four species: Sabellaria bellis Hansen, 1882; Travisia amadoi Elías et al., 2003a: Terebellides lanai Solis-Weiss et al., 1991 and Aglaophamus uruguayi Hartman, 1953

“…Close to the fishing port more stress‐tolerant groups such as Pilargidae become dominant. The members of Sigambra , the dominant genus in the present study, are reported to be indicators of organic pollution (Palacios et al. 2005).…”

Combining echo sounding, sediment and biological data to map benthic habitats in a coastal area of the Persian Gulf

et al. 2012

Mapping surveys of coastal benthic habitat in Qeshm Island Geopark, Persian Gulf, were conducted using a combination of biological, sedimentological and echo‐sounding data. The survey area covered approximately 233 km2 in a depth range of 5–25 m, and the data were acquired from a single beam echo sounder, grab, video and still photography. Sediment and macrofauna samples were collected by grab at 76 stations and subjected to classification and ordination analyses. Two acoustic classes were identified differentiating along the near/offshore axis. Sediment texture was dominated by fine grain sizes, with five distinct sub‐sediment types. In total, 214 macrobenthic taxa were identified, of which polychaetes accounted for 60%. Other dominant groups included young sponges, nematodes, malacostracan crustacean, bivalves, ostracods and ophiuroids. Underwater videos and still photos integrated the macrofaunal and sedimentary data and revealed a range of biogenic sedimentary features such as burrows and tubes. The biological data identified six main biological assemblages showing an inshore/offshore pattern. The macrobenthic abundance did not demonstrate a significant difference with depth, although polychaetes were positively correlated with depth. The highest abundance and species richness were observed at median depths. Species distribution and diversity did not show any correlation with sediment type. A preliminary habitat mapping of the south coast of the Qeshm Island Geopark has been carried out, integrating acoustic, sediment and biological data.
