Coast to toast

GeocoverNew Zealand Geographic‘s new issue (#86, July-August) includes a taster of the sort of thing you’re going to get in Hot Topic: the book. I particularly like the graphics created to support my text: the header pic of New Zealand as cheese on toast is spectacular… This article focuses on the science and what it’s telling us. I’ll do a follow-up on how we might cope in due course.

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.
