DIS­RUPTED SEX LIVES

BBC Earth (Asia) - - Science -

Ris­ing tem­per­a­tures could have a pro­found in­flu­ence on the sex lives of rep­tiles, mak­ing it harder for them to find a mate. In green sea tur­tles, for ex­am­ple, hatch­lings from eggs in­cu­bated above 29°C are fe­male, while those from eggs in­cu­bated at cooler tem­per­a­tures are male. Pop­u­la­tions are usu­ally fe­male-dom­i­nated, but in 2016, a study in the Caribbean found that only 16 per cent of green sea tur­tles are male, and pre­dicted that by 2030, the per­cent­age will fall to just 2 per cent due to cli­mate change.
