Changes in the decapod fauna of an Arctic fjord during the last 100 years (1908-2007)
Whereas Arctic benthic decapods are not a species-rich group, they can dominate the local epifauna and play important roles in the ecosystem. We studied the decapod fauna from Isfjorden (Svalbard, Norway, 78A degrees N) by sampling from 22 stations and comparing with 50 and 100-year-old data from th...

Our data provide no evidence of changes in the species composition of decapods during the last 50 years. Hence, we do not observe the poleward shift of species found in several pelagic communities in the North Atlantic.
