In order to understand the distribution and abundance of a given species, we need to know its evolutionary history,the resources it requires, its demographic vital rates, its interactions with conspecifics and other species, and theeffects of environmental conditions (Begon, Townsend, & Harper, 2006). At the edges of the present distribution of a particular species, organisms are exposed to the extreme of variability in the environmental variables that definetheir natural habitat. In those environments, a small change of any of the variables can strongly affect the survivorship of a given species.
