In a new study published by the British Ecological Society, experts warn that there is much uncertainty regarding how mammals will respond to climate change, especially in regions that are the most vulnerable.
While it is known that nearly 25 percent of mammal species are threatened with extinction, the threats associated with climate change are complex and not well understood. This is because different environmental changes have multiple effects on the lives of animals, including survival and reproduction.
The current study, conducted by an international team of researchers from 15 institutions, has found that most research on terrestrial mammals has not investigated the full range of effects brought on by climate change.

A new scientific review has found there are significant gaps in our knowledge of how mammal populations are responding to climate change, particularly in regions most sensitive to climate change. The findings are published in the British Ecological Society s
Journal of Animal Ecology.
Nearly 25% of mammal species are threatened with extinction, with this risk exacerbated by climate change. But the ways climate change is impacting animals now, and projected to in the future, is known to be complex. Different environmental changes have multiple and potentially contrasting, effects on different aspects of animals lives, such as reproduction and survival (known as demographic rates).
