Research Description Paul Hertz specializes in animal physiological ecology and evolution, reptile ecology and behavior, and herpetology. Reptiles, as ectothermic vertebrates, provide a model system for studying adaptation to spatial and temporal variation in the physical environment. Dr. Hertz's early research focused on the evolution and interaction of behavioral and physiological traits that compensate for geographic and seasonal shifts in operative temperatures. More recently, Dr. Hertz has defined a protocol for using null hypotheses in field experiments to evaluate the extent and effectiveness of temperature regulation and its effect on resource partitioning in West Indian anoles. He has also investigated the role of light intensity in microhabitat selection by thermoregulating and non-thermoregulating Anolis species. Several years ago Dr. Hertz collaborated with two European colleagues on a study that determined the relative contributions of different behavioral mechanisms to temperature regulation in a European lacertid and evaluated the effects of operative temperatures on its microhabitat selection. Dr. Hertz has recently collaborated with scientists from Washington University, the Smithsonian, and the Cuban Academy of Sciences on a study of the thermal biology and community ecology of sympatric Anolis lizards in western Cuba. He hopes to continue this project in the near future.
