One major geographic pattern in biodiversity is the latitudinal gradient in species richness. As one travels further away from the equator, for most taxa, the number of species declines.

The accumulation of toxic elements poses a significant threat to terrestrial ecosystems, with the patterns and influencing ...

The study, by Dr. David Jablonski of University of Chicago and colleagues, was titled "Out of the Tropics: Evolutionary Dynamics of the Latitudinal Diversity Gradient." ...
