"Hatchlings' swimming abilities are pretty weak, and so they are largely at the mercy of the currents. If they drift to a good site, they seem to imprint on this location, and then later actively go there as an adult; and because they're bigger and stronger they can swim there directly," explained lead researcher Rebecca Scott in a press release. "Conversely, if the hatchlings don't drift to sites that are suitable for adult feeding, you see that reflected in the behavior of the adults, which either do not migrate or they feed in the open ocean, which is not the normal strategy for most turtle species."
These findings come at the heels of a study published this past March that defines the nursery grounds and habitat for Loggerhead sea turtles during the "lost years," too.
How will climate change affect sea turtle sex determination?
Climate change poses a wide range of threats to sea turtles, from stronger storms flooding sea turtle nests to rising sea levels eroding nesting habitat. Now, a recent study published online in the journal Nature Climate Change, "Effects of Rising Temperature on the Viability of an Important Sea Turtle Rookery," sheds light on how climate change could throw the ratio of male to female sea turtles off balance.
