Incubation and water temperatures influence the performances of loggerhead sea turtle hatchlings during the dispersal phase
Abstract Artificial manipulation of incubation temperature has been proposed as a potential strategy for mitigating the effects of climate change on sea turtles for which sex determination is temperature-dependent, but thermal manipulation may also affect hatchling survival. Here, we demonstrated th...
