Contribution of differential diversification rates to current broad-scale patterns os species richness in south american birds

Multiple studies have revealed relationships between current spatial patterns of species richness and various environmental factors. However, little is known about the origin of these relationships in terms of processes of speciation, extinction, and immigration. The diversification rate hypothesis...
