Sea turtles and temperature

This presentation considers the effects of temperature on all stages of the life histories of sea turtles. Most attention is paid to the fact that sex in turtles is determined by environmental temperature during incubation, rather than by chromosomes, making them potentially vulnerable to global warming. Many populations of hatchlings show strong female biases. The effects of temperature on incubation duration and the internesting intervals of female parents are also considered. Hibernation and cold-stunning will also be described. Finally, a section of the talk will be devoted to the Leatherback Turtle Dermochelys, which forages in cold temperate waters and is gigantothermic/endothermic.
