In this episode, Amy speaks with Jeff Podos, a Professor in the Department of Biology at the University of Massachusetts - Amherst and a previous President of the Animal Behavior Society.
They start out discussing how a diet of fruit can explain elaborate sexual ornamentation in animals. Then, we learn about Jeff's work on Darwin's finches in the Galápagos Islands. They also talk about what drives bellbirds to sing such piercingly loud songs.
After the break, Amy and Jeff talk about his new approach to teaching Animal Behavior (sparked by the pandemic), and his recent sabbatical in Brazil. They close by discussing the future of the field of animal behavior.
This week's Two-Minute Takeaway comes from Ellen Pasternack (@EllenPasternack), a final year PhD student at The University of Oxford. She studies the mechanisms of sexual selection through behavioral observation of domestic chickens and their ancestor species, the red junglefowl. She's particularly interested in the role of female resistance to mating attempts.
Select papers relevant to today's show:
1. Costs, constraints, and sexual trait elaboration
2. Extremely loud mating songs at close range in white bellbirds
3. Correlated evolution of morphology and vocal signal structure in Darwin's finches
