![]() Sea turtle mothers already have to lumber out of the water to find a good spot to nest, which can be difficult in areas where humans have built seawalls. “We have found that even if they do change the timing of their nesting, that’s not going to be sufficient to maintain the temperatures of current nesting grounds,” Fuentes said. Turtles have adapted to altered climates over millions of years, but today’s rapid changes could happen too quickly for them to evolve, she said. “Additionally, hatchlings that come out of warmer nests are much smaller and often slower.”Ī study led by FSU professor Mariana Fuentes that was published recently in the Global Change Biology journal found sea turtles will have to nest much later or much earlier than they currently do to cope with changing environmental conditions.Įven that may not be enough for every species, said Fuentes, who works in FSU’s Department of Earth, Ocean and Atmospheric Science. “So the warmer the nest is, the more likely that nest is to produce females,” Perrault said. ![]()
