Invertebrate community assembly along proglacial chronosequences in the high Arctic
Summary Invertebrate community assembly is described for two contrasting proglacial chronosequences (over 1900 years) at Kongsfjord, W. Spitsbergen, Svalbard. Three hypotheses were tested: (1) community assembly is deterministic, directional and predictable; (2) succession is inextricably linked to...
