Abstract

Understanding macroevolutionary patterns of geographic range evolution requires developing techniques able to detect their constituent mechanisms. One of the main objectives of my post-doctoral project is to identify factors leading to the decrease in distribution range size experienced by snake-like lizards. Thermal physiology is a potential factor because burrowing snake-like lizards, despite inhabiting hot and open environments, typically evolve low thermal tolerance and a preference for low temperatures. In this way, their avoidance of hot temperatures might make their geographic ranges shrink in those hot environments. However, linking behavioral thermoregulation and thermal physiology to geographic range size is a current challenge for ecophysiology. Dr. Michael Angilleta is a renowned leader in thermal physiology research who has raised important infrastructure for developing such links at the University of Arizona (Tempe). We will co-work on the use of voluntary maximum temperatures (VMT) of lizards for identifying physio-behavioral constrains on geographic range size. During my phd-post doctoral research I have gathered promising preliminary data on the performance of this parameter and data on VMT of lizards of different families. We will develop a strong experimental basis for this parameter so as to provide a fast and general method for identifying how high temperatures act on lizards' behavior/physiology to constrain their geographic range.
