Invading Trees?

Dr Gareth Rees, Researcher at the University’s Scott Polar Research Institute talks about the Arctic tree line – and questions the reliability of vegetation predictions. He suggests that the relationship between climate warming and tree growth is not as simple as initially thought. Over the last century, the Earth’s surface temperature increased by about 0.7ºC […] … learn more→

Parenting comes at a price for male fish

Being a great dad can mean starving to protect the kids, putting up with a jealous spouse – and often, dying young. At least, if you’re a cardinalfish.
