| Abstract: | Based on the species composition and abundance of zooplankton from 43 stations in the western Arctic Ocean, community structures and geographic distributions, as well as relations between zooplankton communities and environmental conditions were investigated. The species composition and abundance were compared with the previously published results to examine possible changes an community level. Three zooplankton communities were identified with a cluster analysis: a high latitude deep ocean community located in the Canadian Basin and Chuchi Plateau;a shelf community located in the central Chukchi Sea;a neritic transition community including station along the Alaska coast and in the north of Chukchi Sea. The deep ocean community was less in total zooplankton abundance, and dominated by copepods. The most important dominant species include Oithona spp., Scolethricella minor, Calanus hyperboreus and Metridia longa. Barnache cypris, Calanus glacialis and Pseudocalanus newmani were the most important dominant species in the shelf community, and P.newmani, banarcle nauplii and Acartia longiremis were of the most importance in the neritic transition community.Barnacle cypris was recorded as dominant taxon in all communities, with the highest average density of 573.2 ind/m-3 observed in the shelf community. The deep ocean community inhabited in high latitude area characterized by low temperature and low chlorophyll a concentration. The shelf community distributed mainly in the central Chukchi Sea with high temperature and low chlorophyll a concentration and at several stations with low temperature and high chlorophyll a concentration.The stations from all these three habitats were included in the neritic transition community. It was indicated that zooplankton community is rather steady in high latitude areas, but varies significantly in the Chukchi Sea due to both environmental influences and local development. Though the species composition was different from the previous results, it was induced mainly by various sampling date and gears, rather than long-term changes. |
