Responses of terrestrial polar arthropods to high and increasing temperatures ...
Terrestrial arthropods in the Arctic and Antarctic are exposed to extreme and variable temperatures, and climate change is predicted to be especially pronounced in these regions. Available studies on insect ecophysiology typically focus on the ability of species to tolerate the extreme low temperatu...

Terrestrial arthropods in the Arctic and Antarctic are exposed to extreme and variable temperatures, and climate change is predicted to be especially pronounced in these regions. Available studies on insect ecophysiology typically focus on the ability of species to tolerate the extreme low temperatures that can occur in these regions, whereas studies investigating species’ plasticity and the importance of evolutionary adaptation to periodically high and increasing temperatures are limited.
