Turtle Population Sex Ratios at Urban vs. Rural Locations

by Abigail Conklin

In many turtle species, the sex of an individual is strongly influenced by the environmental temperatures it experiences prior to hatching. Climate change and urbanization may raise the temperature of nesting habitat enough to strongly skew sex ratios in freshwater turtles, but data on that question are lacking. I sampled multiple urban and rural sites to examine the effect of urbanization on the sex ratio of turtle populations. Three urban sites and three rural sites were sampled.
