How does behavior evolve? We're interested in the ecological factors that influence social behaviors and the physiological mechanisms that underlie those behaviors. Most of our work uses lizards in the genus Anolis, or anoles, but we're also beginning to explore the diversity of lizards that occur at our local field sites in south-central Texas. We use field observations, laboratory experiments, molecular genetics, neuroendocrine techniques, and comparative methodology to explore behavioral evolution.
August 2013 - We've just published an exciting article in Naturwissenschaften on the thesis work of lab alum Ellee Cook, in collaboration with Troy Murphy. Check out the paper on the lab Publications page.
July 2013 - Chris Robinson, Bonnie Kircher,and Michele Johnson traveled to the Bahamas to collect anoles and observe curly-tails.
May 2013 - We're funded!! Michele Johnson has been awarded a four-year grant from the National Science Foundation entitled "Behavioral convergence in Caribbean lizards: morphological and physiological mechanisms."
