Male aggression varies with throat color in 2 distinct populations of the mesquite lizard
I research methods for delimiting species boundaries. I work mostly with Sceloporus grammicus, a lizard species found in Mexico, but I have also published papers on other lizard species, malaria mosquitoes, meadow jumping mice, and crickets. Along with species boundaries issues I do research in phylogentics, population genetics, and hybrid zones. I am always looking for good undergraduate researchers so if you are interested email me your CV. Abstracts of my research are posted below.
Dr. Marshall spent a week in Nuevo Leon and Tamaulipas, Mexico helping graduate student Beth Bastiaans (University of California, Santa Cruz) and Gen (undergraduate student UCSC) collecting live lizards in the field and bringing them back to the lab in Torreon. Above Gama (Professor at Universidad de Juarez del Estado de Durango), Beth, and Gen set up lizard chambers in preparation for mate selection and male aggression trial.
