Tardigrades and oribatid mites in bryophytes from geothermally active lava fields (Krafla, Iceland) and the description of Pilatobius islandicus sp. nov. (Eutardigrada)
In polar regions, apart from tundra and glaciers, geothermally active areas with elevated temperatures are important elements of ecosystems. One such geothermally active region characterized by mosaic ecosystems and vast areas covered by recent lava fields is Iceland. The aim of our study was to exp...
