Title

Distribution of polychaetes in the Laptev Sea and New Siberian shoal and its relation with environmental factors

Abstract

In this paper, the distribution of polychaetes in the Laptev Sea and New Siberian shoal is analyzed based on 115 bottom trawl samples taken in August–October 2014. Polychaetes were the most species-rich group (83 taxa, 74 identified to the species level). Two faunistic assemblages of polychaetes, coastal and offshore ones, were distinguished. The boundary of their distribution did not coincide with the boundaries of assemblages defined for the other groups of the trawl zoobenthos. In the southwestern part of the Laptev Sea it coincided with the boundary between positive and negative near-bottom temperatures, and in the New Siberian shoal it coincided with a 28 PSU isohaline. The coastal assemblage was dominated by species that were widespread in the sea area. Only five carnivorous and detritovorous species were typical for the complex. The offshore assemblage included 26 characteristic species belonging to all trophic groups. Besides, the proportion of sparsely distributed species was much higher in the offshore assemblage compared to the coastal one.
