Enjoy this blog on Sex ratios, climate change, and giant tortoises by Dr. Patrick Moldowan. Patrick provides a great review of the paper by Deem et al (2023) published earlier this year. In the paper, we investigated the roles of nest location and temperature in influencing the sex of hatchling tortoises. The findings from this study offer important information for the conservation of giant tortoises, among other species with temperature sex determination (TSD), in our changing world.
