Webb10 juli 2024 · High temperatures and low water availability are relentless stressors for many endotherms, including birds; yet birds persist in deserts. While physiological adaptation probably involves metabolic phenotypes, the underlying mechanisms (plasticity, genetics) are largely uncharacterized. WebbAlbert Farrell Bennett is an American zoologist, physiologist, evolutionary biologist, author, and academic.He is Dean Emeritus of the School of Biological Sciences at University of California, Irvine.. Bennett's research focuses on exploring the interaction between living systems and their environment, specifically focusing on temperature and energy exchange.
