Document Summary
In ecology we are concerned about: distribution, abundance, and diversity. High temps allow more water to evaporate; places near the equator are warm, wet and therefore super productive; places far from the equator are dry precipitation. Latitudinal diversity is one of the most well established large scale geographic patterns.

You will have a higher extinction rate if you have a higher species pool (more opportunities for extinction, more competition, etc. *will be given a graph to interpret on the midterm *
