Isolation Barrier Higher Biology. These factors may produce distinct. The environment may impose an external barrier to reproduction, such as a river or mountain range, between two incipient species but that external barrier alone will. • reproductive isolation of populations can be temporal, behavioural or geographic. Physical barriers like mountains, rivers, or oceans prevent individuals of different populations from mating due to their inability to access each other’s habitats. Premating isolation is a form of reproductive barrier that reduces the frequency of interspecific mating, and it can be a potent mechanism for. However, little is known about the transition from partial to strong reproductive isolation (ri) and the completion of speciation.
