Some species of monkeys and apes are in danger of being wiped out by global warming, say scientists.
A new study suggests that many of the animals will not survive if temperatures around the world rise by just 2C. Those that cannot adapt could be driven to extinction, experts warn.
The species most at risk are the already endangered gorillas and colobine monkeys, say the British researchers.
The study, published online in the journal Animal Behaviour, pinpoints which primates are are most threatened by climate change.
Old World populations in Africa will be hardest hit, especially species such as colobines whose diets are mainly leaf-based, the scientists predict.
