ecological isolation

views updated Jun 11 2018

ecological isolation The separation of groups of organisms as a result of changes in their ecology or in the environment in which they live. This is one of the processes leading to speciation, since there will be a restriction in the movement of genes between groups thus separated, and changes in gene frequencies may occur owing to local selection or drift until eventually the groups may be so divergent that reproductive barriers exist.
