Amanda S. Cicchino, Cameron K. Ghalambor, Brenna R. Forester, Jason Dunham, W. Chris Funk
2024, Proceedings of the Royal Society B (291)
Temporally variable climates are expected to drive the evolution of thermal physiological traits that enable performance across a wider range of temperatures (i.e. climate variability hypothesis, CVH). Spatial thermal variability, however, may mediate this relationship by providing ectotherms with the opportunity to behaviourally select preferred temperatures (i.e. the Bogert effect)....
