Document Summary

Physical factors and species interactions are important regulators of species distributions at local scales. But global and regional scale processes are also important in determining the distributions and diversity of species on earth. Is the study of patterns of species composition and diversity across geographic locations. For example: the amazon rainforest is the most species-rich forest in the world, with approximately 1,300 tree species. In contrast, the boreal forests of canada have only two tree species that cover vast areas. Spatial scales are interconnected in a hierarchical way, with of species diversity and composition at one spatial scale conditions for patterns at smaller spatial scales. Global scale the entire world. species diversity and composition: species have been isolated from one another, on different in different oceans, by long distances and over long periods, rates of speciation, extinction, and dispersal help determine. Regional scale areas with uniform climate; the species are bound to that region.
