How temperature guides where species live, where they’ll go

A new study could prove significant in answering among the most enduring questions for ecologists: Why do species live where they do, and what are the factors that keep them there? The ranges of animals in the world’s temperate mountain areas — often presumed to be determined by competition — may actually be determined more by temperature and habitat. The findings indicate that species living in temperate mountain habitats could face even greater repercussions from climate change than previously thought.
