How do hormones help animals cope with stress, seasons, and climate change? What is allostasis?

In this episode, our guest is John Wingfield, Emeritus Professor of Physiology and Behavior, at the University of California, Davis. John helped develop many fundamental hypotheses in the field of endocrinology through his work on wild bird populations, in particular the white-crowned sparrow. Fran Bonier, a former PhD student of John’s and now Professor of Biology at Queen’s University in Kingston, Ontario, also joined us for the chat.

We talk with John about how he got interested in understanding wildlife endocrinology, and discuss how he helped formulate the “challenge hypothesis”, “emergency life history hypothesis”, and the concept of “allostasis”. And at the end, John gives some advice to early career researchers, based on his experience as the head of the Biology Directorate at the National Science Foundation.
