Abstract:
The vegetation pattern of siliceous boulder snow beds (Dicranoweision crispulae all. nov. prov.) of Svalbard was investigated by using transect studies in several places on Spitsbergen. Dicranoweisia crispula is the best diagnostic species. It is found throughout the whole snow bed, is a good differential species against Racomitrium lanuginosum communities above the snow bed, and does not occur on basic rocks. Three Andreaea spp. are also among the most important members of these communities. They are all acidophilous, but with different pH preferences. Eight weakly acidophilous species lacking both on basic and on gneissic/granitic rocks, are reported from Svalbard. Half of these are characteristic species of Dicranoweision crispulae on Svalbard.
