Turtles' mating habits protect against effects of climate change
Date:1/24/2012

am also carried out satellite tracking to discover that males cover thousands of miles of ocean within one breeding season. This suggests they could have also been mating with females at other sites in Turkey or North Africa.

Lead researcher University of Exeter PhD student Lucy Wright said: "It is fantastic to know that there are so many males fathering offspring in this population of green turtles. There is great concern that a lack of males could lead to inbreeding in small populations of marine turtles, potentially causing a population crash. However our research suggests that there are more males out there than expected considering the female-biased hatchling sex ratios and that their mating patterns will buffer the population against any potential feminising effects of climate change."

Corresponding author Dr Annette Broderick added: "Climate change remains a great threat to marine turtles, but our ongoing research will help us focus on where the priority areas are for management that may help them cope with future change."
