Document Summary
Thus, ecological processes can be attributed to patterns of variation on local species richness. New species can form on large islands, thus higher species richness than only. Bio120h lisa zhao 2011 | page 5 colonization. Extinction rate may increase if competitive exclusion increased w/ species richness. Extinction rate might decrease if mutualistic relationships and alternative pathways of. Nrg flow buffered processes that lead to extinction. Increased rates of speciation, decreased rates of extinction, or both lead to higher species richness at equilibrium point of diversity.

Envmtal heterogeneity allows species to coexist b/c they can specialize on diff. parts of the niche space. Disturbances (ex. tree falls) are imp. sources of envmtal heterogeneity in forests.
