Climate is no ubiquitous explanation of fluctuations in reindeer numbers

Exploitation of natural resources, such as forestry or gas and oil extraction, and management practices may have faster and greater impacts on reindeer populations than does climate change, a study finds. However, climate change should not be forgotten or underestimated, since reindeer are adapted to cold temperatures and therefore susceptible to temperature increases.
