About

Professor Johannes Overgaard is a faculty member at Aarhus Universitet in Denmark. His research primarily focuses on the physiological responses of ectotherms to temperature variations, exploring areas such as thermal limits, heat stress, and metabolic adaptations. Recent publications include studies on the impacts of sublethal heat stress on black soldier flies and the effects of dehydration on locust heat tolerance in the context of climate change.
