However, researchers analysing five caribou populations discovered populations living in the northern Arctic – where things are shifting most rapidly – were having offspring earlier to coincide with the changes in their environment, indicating populations are adapting to climate change.

However, the southern caribou populations experiencing less rapid environmental changes had offspring at their usual time.
