Boreal-arctic species dominate the biomass of benthos in the Barents Sea (as well as throughout the arctic shelf), and have an optimum temperature range lying within the long-term temperature mean of the region. According to this latter theory, any deviation from the long-term mean has a negative impact on boreal-arctic species reproduction, abundance, and biomass. Some studies suggest that the de...

Climate variability affects fish in a variety of ways and throughout its life cycle.  Sea temperature is the variable that has received the most attention from researchers in terms of its effects on both pelagic and demersal fish.  Successful individual growth often occurs within a limited thermal range that differs among species and even between developmental stages within the same species. Gener...
