Final answer:
Temporal isolation is a prezygotic barrier causing reproductive isolation among species by having different breeding times, for example, two frog species that breed during different months cannot interbreed.
Step-by-step explanation:
Temporal isolation is an example of a prezygotic reproductive barrier that prevents species from interbreeding due to differences in their breeding schedules.
This occurs when two species share the same environment but have different times of the year for reproduction, often annually.
For instance, one frog species may reproduce from January to March and another from March to May. As a result, even though they live in the same area, the difference in breeding periods precludes them from mating.
Temporal isolation is a key aspect of reproductive isolation, in which different mechanisms ensure that there is no gene flow between species.
