Tardigrades of the Australian Antarctic Territories: the Windmill Islands, East Antarctica

Six species of tardigrades, Pseudechiniscus suillus, Macrobiotus sp., Hypsibius antarcticus, Ramajendas frigidus, Diphascon chilenense and Diphascon pingue were extracted from mosses and lichens from the ice‐free regions of the Windmill Islands near Casey Base, East Antarctica. Significant positive associations were found between the three common species (Pseudechiniscus suillus, Hypsibius antarcticus, Diphascon chilenense) and bryophytes, whereas strong negative associations were found between these species and algae and lichens. There were additional interspecific associations between the common species of tardigrades as well as between tardigrades, nematodes and rotifers.
