Polar ectotherms more vulnerable to warming than expected

Simon Bahrndorff et al. Trends Ecol Evol. 2025 Jul.

Abstract

Polar regions are heavily impacted by climate change. Yet, vulnerability assessments suggest little concern about heat-related challenges for polar terrestrial ectotherms. These conclusions are based, however, on assumptions and extrapolation from temperate regions; the limited data available suggest that polar ectotherms are more sensitive to warming than previously recognized.

Keywords: climate change; conservation; insects; polar regions; vulnerability assessment; warming.
