201510fau-turtlesOctober 15, 2015 - Researchers from Florida Atlantic University have just published the results of a four-year study in the journal Endangered Species Research on the effects of turtle nest temperatures and sand temperatures and on hatchling sex.

"The shift in our climate is shifting turtles as well, because as the temperature of their nests change so do their reproduction patterns," said Jeanette Wyneken, Ph.D., professor of biological sciences in FAU’s Charles E. Schmidt College of Science. "The nesting beaches along Florida’s coast are important, because they produce the majority of the loggerhead hatchlings entering the northwestern Atlantic Ocean. If climatic changes continue to force the sex ratio bias of loggerheads to even greater extremes, we are going to lose the diversity of sea turtles as well as their overall ability to reproduce effectively. Sex ratios are already strongly female biased...that’s why it’s critical to understand how environmental factors, specifically temperature and rainfall, influence hatchling sex ratios."
