Increased importance of cool‐water fish at high latitudes emerges from individual‐level responses to warming
High latitude ecosystems are experiencing the most rapid warming on earth, expected to trigger a diverse array of ecological responses. Climate warming affects the ecophysiology of fish, and fish close to the cold end of their thermal distribution are expected to increase somatic growth from increas...

High latitude ecosystems are experiencing the most rapid warming on earth, expected to trigger a diverse array of ecological responses. Climate warming affects the ecophysiology of fish, and fish close to the cold end of their thermal distribution are expected to increase somatic growth from increased temperatures and a prolonged growth season, which in turn affects maturation schedules, reproduction, and survival, boosting population growth. Accordingly, fish species living in ecosystems close to their northern range edge should increase in relative abundance and importance, and possibly displace cold‐water adapted species. We aim to document whether and how population‐level effects of warming are mediated by individual‐level responses to increased temperatures, shift community structure, and composition in high latitude ecosystems. We studied 11 cool‐water adapted perch populations in communities dominated by cold‐water adapted species (whitefish, burbot, and charr) to investigate changes in the relative importance of the cool‐water perch during the last 30 years of rapid warming in high latitude lakes. In addition, we studied the individual‐level responses to warming to clarify the potential mechanisms underlying the population effects. Our long‐term series (1991–2020) reveal a marked increase in numerical importance of the cool‐water fish species, perch, in ten out of eleven populations, and in most fish communities perch is now dominant.
