The puma or mountain lion, Puma concolor, ranges from the Canadian Yukon to the tip of South America. Body size of mammals also correlates well with latitude (Bergmann’s rule); the larger pumas live at high latitudes. Consequently, this variation in body size has been interpreted as the result of selection for efficient temperature regulation. Why are homeothermic animals often larger at high latitudes?

Ecological adaptations

An ecological adaptation is any morphological, physiological, or behavioral trait of an organism that allows it to survive and reproduce in a habitat or ecosystem. Adaptation is a biological mechanism by which an organism gradually gets more acclimated to its surroundings.
