William and Ingrid Rea Assistant Curator of Bird Conservation
Biography
Dr. Chase D. Mendenhall is an ecologist and evolutionary biologist with degrees from the University of Wyoming and Stanford University. Mendenhall’s research emphasizes the role cooperation plays in the natural world to create cells, build bodies, and determine behaviors that challenge traditional narratives of what it means to be an individual, a male, a female, or part of a family or group. Using novel mathematical frameworks, Mendenhall incorporates altruism and cooperation into existing theories of natural selection. His research uses cooperative behavior birds evolve to successfully raise offspring to empirically test hypotheses.
Mendenhall is also an expert on extinctions, especially how they play out differently on islands compared to mainland continents. Some of his research has examined the benefits of colonization and extinctions in different places. For example, bees and birds colonizing a countryside can pollinate crops and eat pests. Conversely, rat, cat and some insect extinctions on oceanic archipelagos rescues rare ecosystems and benefits the people.
