Abstract
Many reptiles have temperature-dependent sex determination (TSD), where the temperature experienced by eggs during incubation determines whether the embryo becomes male or female. Because of this, weather patterns influence the number of males or females being produced in a given year. Over longer time scales, climate changes can produce shifts in population sex ratios, which can be detrimental to population health. Understanding how populations of such reptiles might respond to climate change is important, since most reptiles with TSD are threatened or endangered.
