Abundance and diversity of the Amphipoda (Crustacea) from the Greenlandic shelfEntry ID: ArcOD_2006B1
Abstract: The species composition of Amphipoda (Crustacea: Malacostraca: Peracarida) of the Greenland shelf south of 65°N was investigated by means of 18 epibenthic samples over a sampling period of three years (2001, 2002, 2004). The samples were taken using a Rauschert sledge in depths between 106 and 251 m. In total, 62,205 specimens were identified belonging to 154 species. The amphipods from the South ... Greenland shelf represent in general a homogeneously distributed community with respect to evenness (J’), diversity (H’) and Hurlbert’s rarefaction E (S500). Multivariate analyses of the species abundances divided the amphipods into a southeastern and southwestern fauna. Among the species most contributing to the separation between East and West, Hardametopa nasuta, Photis reinhardi and Phoxocephalus holboelli were identified. With respect to evenness and diversity, the amphipod community was stable over the three years. We used the WORMS database to present species in this metadata.
Purpose: To assess species composition, abundance, distribution, diversity and temporal changes of the benthic Amphipoda (Crustacea: Malacostraca: Peracarida) of the South Greenland shelf.

Quality ATTRIBUTE ACCURACY REPORT: A 0.5 mm mesh was used for sieving. The accuracy of the sampling device is unknown, but replicability seems to be high, i.e. variability between replicates was relatively low. The accuracy for trawled sledges is generally unknown since the trawled distance always differs, also between replicates. Additionally, the trawling position is derived from the ship’s GPS and can ... deviate from actual trawling positions by up to 100 m.
LOGICAL CONSISTENCY REPORT: The same procedures were used at all sites and for all species; findings should be consistent.
COMPLETENESS REPORT: Complete as authors know it.
HORIZONTAL POSITIONAL ACCURACY REPORT: GPS coordinates from ship
PROCESS DESCRIPTION: Epibenthic sampling by means of a Rauschert sledge see
