Media LLC","grobid_abstract":"A benthic species inventory of 1,125 taxa was compiled from various sources for the central Arctic deeper than 500 m, and bounded to the Atlantic by Fram Strait. The inventory was dominated by arthropods (366 taxa), foraminiferans (197), annelids (194), and nematodes (140). An additional 115 taxa were added from the Greenland-Iceland-Norwegian Seas (GIN). Approximately half of all taxa were recorded from only 1 or 2 locations. A large overlap in taxa with Arctic shelf species supports previous findings that part of the deepsea fauna originates from shelf species. Macrofaunal abundance, meiofaunal abundance and macrofaunal biomass decreased significantly with water depth. Robust diversity indices could only be calculated for the polychaetes, for which S, ES(20), H' and Delta+ decreased significantly with water depth, and all but ES (20) decreased slightly with latitude. Species evenness increased with depth and latitude. No mid-depth peak in species richness was observed. Multivariate analysis of the Eurasian, Amerasian and GIN Seas polychaete occurrences revealed a strong Atlantic influence, the absence of modern Pacific fauna, and the lack of a barrier effect by mid-Arctic ridges. Regional differences appear to be moderate on the species level and minor on the family level, although the analysis was confounded by a lack of methodological standardization and inconsistent taxonomic resolution.

Abstract: Benthic research in Arctic seas has been intensified since the late 1980s, being considerably promoted by an increased public awareness of the global climate significance of polar regions and the opening of the Russian Arctic to foreign researchers. As a result, our knowledge on the Arctic benthos has been markedly enhanced, leading to the need to revise some widespread concepts about its ecological structure and function, particularly with regard to the often-cited disparities between the Arctic and the Antarctic. Most generally, the novel data clearly demonstrated that the various Arctic seas differ to a large extent in geographical and environmental setting, impact of fluvial run-off, pelagic production regime, strength of pelagic-benthic coupling and, hence, food supply to the benthos. This spatial variability inevi- tably results in surprisingly pronounced ecological divergences and impedes all efforts for large-scale generalizations of local and regional findings. ...</p><div
