Some Statistical Aspects Related to the Study of Treeline in Pico de Orizaba

Abstract

In low latitude regions of the Earth we find surface temperature near 0° C in tropical alpine environments (). In these environments temperature and pressure rapidly decrease as the altitude increases and so organisms must adapt to them until they reach their physiological tolerance limits. A clear example of this is treeline at thermal gradients that represent an abrupt transition in life form dominance. In Pico de Orizaba, Mexico (19° N), there are such environments which can be used as plausible analogues for ancient and future life on Mars.
