WebIn circumstances where populations of invasive species occur across variable landscapes, interactions among invaders, their parasites, and the surrounding environment may establish local coevolutionary trajectories for the participants. This can generate variable infection patterns when parasites in … WebAllopatric speciation occurs when an organism's population becomes separated or isolated from its main group. The word sympatric is derived from the English prefix sym-, which means "same" or "together," and the Greek word patris, which means "fatherland." This type of speciation occurs in populations that are not geographically isolated.
