High-Arctic gamasid mites (Acari, Mesostigmata): community composition on Spitsbergen, Svalbard
This study investigates assemblages of mesostigmatid mites on Spitsbergen, in the Arctic archipelago of Svalbard, Norway. Soil samples were collected from three areas with differing vegetational communities in Adventdalen. The greatest gamasid mite density and species diversity was observed at the l...

This study investigates assemblages of mesostigmatid mites on Spitsbergen, in the Arctic archipelago of Svalbard, Norway. Soil samples were collected from three areas with differing vegetational communities in Adventdalen. The greatest gamasid mite density and species diversity was observed at the location with the richest vegetation cover, Dryas octopetala heath, where 10 species were collected and there was a mean total gamasid mite density of 1000 individuals per m2. The vegetation-poor saline meadow site revealed five species and had a mean total gamasid mite density of 130 individuals per m2. The floristically more diverse Luzula tundra site yielded four species and had a density of 270 individuals per m2. The most frequently found species were Zercon forsslundi, Arctoseius haarlovi and A. weberi.
