How 'staggering' DNA advances could improve our response to climate change

ST. AUGUSTINE, Fla. – Even before sunrise, the tracks of a loggerhead sea turtle on the beach are hard to miss.  

Searching for new nests one morning this summer, Mickler's Landing Turtle Patrol volunteer Lucas Meers leaped from an all-terrain vehicle when he spotted a new scalloped trail in the sand.

"False crawl," Meers called out. For an unknown reason, the turtle returned to the sea without digging a nest for her eggs. That meant Meers didn't have to mark a protected area around the nest.
