摘要

The inter-nesting distributions of green (Chelonia mydas) and flatback (Natator depressus) turtles nesting at the Lacepede Islands, off the Kimberley coast of Western Australia, were studied during the 2009-2010 nesting season. Twenty-two satellite transmitters were attached to green and flatback turtles nesting on the West Island rookery; of these, inter-nesting data were received for 10 green and 5 flatback turtles. Turtles were tracked for 20-83 days during inter-nesting. Key findings from this study indicate that flatback turtles generally have a broader inter-nesting distribution than green turtles. All flatback turtles travelled at least 26 km from the nesting beach during inter-nesting, whereas only 2 of the 10 green turtles travelled more than 10 km from the nesting beach. Individuals of both species travelled to within 5 km of the Western Australian mainland coast during inter-nesting. This study has also demonstrated that satellite transmitters can be successfully deployed on green and flatback turtles early in the nesting season without significant data loss due to transmitters being damaged by nesting and inter-nesting behaviours.
