Allison Litmer is a physiological ecologist whose research examines factors promoting persistence of ectothermic organisms, with an emphasis on reptiles and amphibians. Her workcombines field- and lab-based approaches to mechanistically determine the influence of the abiotic and biotic environment on physiological performance. Much of Allison's work quantifies the sensitivity of individual bioenergetics to temperature, activity, and resource availability. She then uses data on individual physiological ecology to examine population-level dynamics through modeling procedures. Allison also approaches research from a comparative perspective, and has compared the utility of standard methods in thermal biology and population-level differences among closely related organisms. Currently, Allison is researching factors contributing to the ability of nonnative species to persist in urban settings, focused on Common Wall Lizards (Podarcis muralis) in Cincinnati, Ohio.
