In a population of beetles, one leaves and moves to a new population.

A small subset of individuals in a population of mainland birds leaves and starts a new population on a small neighboring island.

During a strong storm, a river changes course and flows through a population of ground beetles; the river is now a barrier between individuals on either side.

Some individuals of flightless insects colonize a new food plant also present in the distribution of their original population, and no longer interact with individuals from the original population.
