Physiological and ecological effects of increasing temperature on fish production in lakes of Arctic Alaska
Abstract Lake ecosystems in the Arctic are changing rapidly due to climate warming. Lakes are sensitive integrators of climate‐induced changes and prominent features across the Arctic landscape, especially in lowland permafrost regions such as the Arctic Coastal Plain of Alaska. Despite many studies...

Abstract Lake ecosystems in the Arctic are changing rapidly due to climate warming. Lakes are sensitive integrators of climate‐induced changes and prominent features across the Arctic landscape, especially in lowland permafrost regions such as the Arctic Coastal Plain of Alaska.

Least Cisco ( Coregonus sardinella ) is a bellwether for Arctic lakes as an important consumer and prey resource.
