Guest guest Posted February 27, 2007 Report Share Posted February 27, 2007 Link: http://www.postchronicle.com/news/science/article_21266267.shtml Study Shows How Marine Turtles Navigate By Staff Feb 26, 2007 A French-led study has determined how marine turtles manage to return to the same beach to lay their eggs after crossing several hundred miles of ocean. Research led by Simon Benhamou of the Center for Functional and Evolutionary Ecology at Montpellier, France, along with other groups, shows the turtles use a relatively simple navigation system involving the Earth's magnetic field, allowing them to return to the same egg-laying site without having the ability to correct for the deflection of ocean currents. The work is expected to result in better conservation strategies for the endangered species. The study is detailed in the journal Current Biology. © UPI Quote Link to comment Share on other sites More sharing options...
