Join us for a great talk about science and some free pizza!
Our speaker this time is Matthew Fuxjager, biologist at Wake Forest University, who studies animal display behavior.
Many animals signal to each other through the performance of physical displays, which often incorporate stunning acrobatics and extraordinary athleticism. In many ways, this behavior represents some of evolution’s finest work, as it involves levels of physicality that outshine even the best human Olympians and sports stars. Thus, my lab explores how such behavior emerges, and I will present my findings that address this issue. I will focus on work that I have recently published in a tropical bird called the golden-collared manakin, as males of this species court females by performing rapid wing movements linked together into a magnificent physical dance display. I will show evidence that much of this behavior relies on androgenic hormones, like testosterone, which act throughout the neuromuscular system. I will also present data that uncovers what testosterone does to the bird’s muscular physiology, allowing it to perform this incredible dance. My aim is to develop an overarching evolutionary framework in which we can begin to understand how an organism’s physiology is re-written to support selection for new— and highly bizarre—reproductive behaviors.
I received my PhD from the University of Wisconsin, Madison, where I studied the hormonal control of aggressive behavior and territoriality in New World rodents. Then, I worked as a post-doc for three years at UCLA in the Laboratory of Neuroendocrinology. This is where I began investigating endocrine effects on courtship behavior, and how differences in these effects can lead to alternate courtship behavior traits. I’m currently an Assistant Professor at Wake Forest University, where my lab examines the mechanisms and evolution of magnificent reproductive behaviors in birds and frogs.
RSVPs are required (for the slice count) by registering for a free ticket to this event. BECAUSE OF THE MEMORIAL DAY HOLIDAY, please get your ticket by 2 PM on FRIDAY, MAY 26. (If you decide to come after this time, you're welcome to attend, but we might not have pizza for you.)
