Multi‐decadal range changes vs. thermal adaptation for north east Atlantic oceanic copepods in the face of climate change
Abstract Populations may potentially respond to climate change in various ways including moving to new areas or alternatively staying where they are and adapting as conditions shift. Traditional laboratory and mesocosm experiments last days to weeks and thus only give a limited picture of thermal ad...

Abstract Populations may potentially respond to climate change in various ways including moving to new areas or alternatively staying where they are and adapting as conditions shift. Traditional laboratory and mesocosm experiments last days to weeks and thus only give a limited picture of thermal adaptation, whereas ocean warming occurring over decades allows the potential for selection of new strains better adapted to warmer conditions. Evidence for adaptation in natural systems is equivocal. We used a 50‐year time series comprising of 117 056 samples in the NE Atlantic, to quantify the abundance and distribution of two particularly important and abundant members of the ocean plankton (copepods of the genus Calanus ) that play a key trophic role for fisheries. Abundance of C. finmarchicus , a cold‐water species, and C. helgolandicus , a warm‐water species, were negatively and positively related to sea surface temperature ( SST ) respectively.
