Geographic isolation is a term that refers to a population of animals, plants, or other organisms that are separated from exchanging genetic material with other organisms of the same species. Typically geographic isolation is the result of an accident or coincidence.
Mechanical isolation is caused by structures or chemical barriers that keep species isolated from one another. For example, in flowering plants, the shape of the flower will tend to match up with a natural pollinator. Plants that do not have the correct shape for the pollinator will not receive a pollen transfer.
Temporal Isolation: Definition and Examples When it comes to temporal isolation, time is the barrier that prevents species from interbreeding and producing sterile hybrids. In this BiologyWise article, we intend to put forth the meaning and some examples of the concept to help you get a good understanding of the same.
