Turtles Nest Earlier in Cyprus Amid Climate Change Adaptation

Research from the University of Exeter reveals that green and loggerhead turtles in Cyprus are nesting earlier each year as a response to rising temperatures due to climate change. This adaptation is critical for maintaining the species' reproductive success, as the temperature of their nests determines the sex of the hatchlings, with higher temperatures producing more females but fewer viable offspring. The study analyzed over three decades of data, showing that loggerhead turtles are nesting approximately 0.78 days earlier annually since 1993. Researchers emphasize the importance of this shift, as they predict severe reproductive challenges for the turtles by 2100 if they do not continue to adapt their nesting schedules. While the current trend indicates a positive response to climate change, future temperature increases and food availability may impact their ability to sustain this adaptation. Overall, the findings underscore the resilience of these ancient creatures in the face of environmental change.
