Justin Waraniak, Sarah Batchelor, Tyler Wagner, Jason Keagy
2025, Science of Total Environment (969)
Extreme weather events, such as heatwaves, are becoming more frequent and intense as a result of climate change. Critically, such extreme weather events can be more important drivers of extirpation and selection than changes in annual or seasonal averages and they pose a particularly large threat to poikilothermic organisms. In...
