The Rummel Lab studies the physiology and mechanics of animal movement. Our research explores how locomotor physiology, thermal physiology, and biomechanics interact to determine an animal’s response to changing environmental conditions on short and long timescales. Using a combination of field and laboratory studies, we aim to understand how temperature affects complex locomotor processes across levels of biological organization, and how animals might respond to climate change and urbanization. We are currently working in two systems: 1) bats, the only mammals capable of powered flight, which also exposes them to a unique thermal environment; and 2) anoles, especially those living in cities, who contend with the thermal environment afforded by urban heat islands.
