For example, the animal species of central and southern Africa are closer to those of southern Asia than those of northern Africa. Australia has only a few placental mammals compared to South America, even though environmental conditions are similar between the two regions. (high immigration rates save species from extinction) "Rescue Effect". They are shown in the figure below. The model considers the interaction of two main parameters, colonization and extinction, and then considers island size and distance from mainland as predictors of the species richness found on each island. Biogeographers use observations from ecology, evolutionary biology, geology, paleontology, and climatology to examine distribution patterns of organisms at local, regional, and global levels. Multiple mainlands = multiple immigration routes, rates. There are many examples I could cite to answer your question, but my favorite is iguana speciation. Biogeography reveals that species that appear to be closely related tend to be geographically close as well, as though groups of species had a common origin at a particular geographic . 17.
