Climate change: sex change

NZ’s iconic tuatara are threatened by climate change. I’ve got the full story in Hot Topic (the book), but Reuters have beaten me to press. Tuatara eggs incubated above 21.5ºC become males, and climate change is already producing a sex imbalance in the population. Male tuatara on a predator-free island near the top of the South Island already outnumber females by 1.7 times, reports Victoria University researcher Jennifer Moore. Full story on TVNZ and the UK Telegraph.
