West Spitsbergen Tardigrada
Abstract:
Fourty nine taxons of non-marine Tardigrada were found in West Spitsbergen area. Among them, twelve species were not previously recorded from that territory. Four species and one subspecies were new and most of them has been described in other papers. They are: Amphibolus nebulosus (Dastych, 1983), Hypsibius montivagus Dastych, 1983, Doryphoribius macrodon Binda, Pilato & Dastych, 1981, Macrobiotus harmsworthi obscurus ssp. nov. and Isohybsibius dastychi Pilato, Bertolani & Binda, 1982. Some quantitative characteristics are given and influence of the kind of rock-substratum and the altitude a.s.l. on Tardigrada-fauna are discussed. These two factors seems to be of great importance for the water-bear species composition.
