Taxonomic composition, density and biomass of soil fauna were evaluated in the sites along a gradient of increase in the biogenic impact of bird colonies, i.e. in polygonal tundra, mossy/lichenous tundra, Calliergon stramineum moss association, and mossy associations near a colony of Little Auks (Alle die). Average total biomass of soil invertebrates increased in this site sequence from 1.1 to 25.0 g wet weight x m-2 (mainly due to collembolans and nematodes). Seasonal dynamics of all groups of soil meso- and macrofauna (Nematoda, Enchytraeidae, Aranei, Acarina, Collembola, Coleoptera, Diptera larvae) is presented and discussed.}, type={Article}, title={Seasonal changes in communities of soil invertebrates in tundra ecosystems of Hornsund, Spitsbergen}, URL={http://ochroma.man.poznan.pl/Content/111005/PDF-MASTER/1995-3-4_245-266.pdf}, keywords={Arctic, Spitsbergen, tundra, soil invertebrates, ornithogenic impact}, }
