GRANT AWARDED: November 2008. Pacific leatherback sea turtles swim throughout the world’s oceans and nest on beaches within the tropics and subtropics. Egg poaching, coastal development and incidental capture in fishing gear has caused the populations to decline by over 90 percent in recent decades, resulting in an endangered listing under the Endangered Species Act. This project determines the relationship between Pacific leatherback sea turtle migrations and oceanographic conditions and assesses the geographic overlap with commercial fisheries in order to provide conservation recommendations.

This study in the journal PLoS ONE is the first support for foraging behaviour differences between populations of this critically endangered species and suggests that longer periods searching for prey may be hindering population recovery in the Pacific while aiding population maintenance in the Atlantic.
