摘要: Abstract The Kara Sea is a little studied high Arctic region located between the Barents Sea, Ocean and Laptev Sea. aim of this study was to reveal spatial distribution mesozooplankton community in relation hydrographic conditions. Our survey first covering most sea, excluding eastern part. Zooplankton samples were collected at 47 stations using Juday net (168 μm, 0.1 m 2 ) August 2012. Copepods dominated total abundance biomass, with Calanus spp. being numerous western part Pseudocalanus area. Cluster analyses revealed four groups differing terms composition, abundance, species richness diversity. regional communities clearly associated habitats defined by their physical (temperature, salinity main currents) biological characteristics (food conditions). domination copepod populations young copepodite stages nauplii suggests early summer-like conditions although meroplankton spring-like mesozooplankton. Principal components analysis showed that temperature determined variations biomass major taxa west, while factor east. Phytoplankton concentrations also have measurable effect on community. average (6±1 g dry mass m –2 higher than adjacent waters, suggesting reproductive potential zooplankton summer season.
