Environmental Warming and Feminization of One of the Largest Sea Turtle Populations in the World

Climate change affects species and ecosystems around the globe []. The impacts of rising temperature are particularly pertinent in species with temperature-dependent sex determination (TSD), where the sex of an individual is determined by incubation temperature during embryonic development []. In sea turtles, the proportion of female hatchlings increases with the incubation temperature. With average global temperature predicted to increase 2.6°C by 2100 [], many sea turtle populations are in danger of high egg mortality and female-only offspring production.
