Explain how habitat loss, overexploitation, pollution, invasive species and climate change reduce populations and increase extinction risk in Cambridge A Level Biology questions.
The aye-aye, Daubentonia madagascariensis, is a mammal, native to Madagascar. Aye-ayes are active at night and make their nests high up in trees. They feed on insect larvae in the trunks of trees.
