UPI quoted biologist Tom Mason at University of Durham (UK) said that body size decreases due to climate change is common in the animal world, especially for many species of fishes, birds and mammals.

One of the reasons is the amount of foods of mountain goats are less nutritious than previous foods, so they have to rest more and spend less time for searching foods.
