The springtail (Hexapoda, Collembola) fauna of Wrangel Island

Analysis of the collembolan fauna of Wrangel Island based on published data and recent sampling was performed. The species richness of springtails on the island (89 species from 41 genera and 12 families) exceeds the levels characteristic of most other insular territories of the Arctic Ocean, except for Greenland and some small islands located within the southern tundra belt. The specificity of the species composition of the springtail fauna on the island depends on a high proportion of species with amphi-Pacific ranges, reflecting its formation within the Beringian Arctic sector. At the same time, the structure of the springtail fauna of the island is rather similar to those of the known tundra faunas of the Siberian sector, with no anomalies being detected.
