Sexual selection in lizards

For my undergraduate research at the University of Virginia, I completed my distinguished majors thesis in the Cox lab. I used ArcGIS to map out our research island and calculate fine scale variation in the density of lizards on the island. I then looked at how local density and sex ratio varied with different sperm traits, with the idea that males in more competitive environments (higher density and male-biased sex ratio) may invest more into traits that aid in sperm competition.
