TestHub · Accepted Answer

The higher temperatures in the tropics cause higher rates of metabolism, ecological dynamics and coevolutionary processes, which generate and maintain higher biodiversity compared with the temperate and polar regions.

Diversity of communities over a landscape is termed as γ (gamma)-diversity. It reflects the diversity of species occupying individual habitats (alpha-diversity) combined with a measure of the heterogeneity between the habitats (beta-diversity).
