Detailed explanation-1: -Examples of temporal isolation include differences in mating behaviors or fertility due to the time of day, time of year, or varied mating cycles. Two species which are temporally isolated long enough may eventually accrue enough genetic differences that they will no longer be able to interbreed.

Detailed explanation-2: -Temporal isolation happens when two or more species reproduce at different times. For example, three species of orchid live in the same rain forest. Each species has flowers that last only one day and must be pollinated on that day to produce seeds.

Detailed explanation-3: -Examples of Temporal Isolation An oft-cited example of reproductive isolation resulting from differences in the mating season is that of the two toad species, the American toad (Anaxyrus americanus) and Fowler’s toad (Bufo fowleri).

Detailed explanation-4: -Two mechanisms of speciation are allopatric (“other fatherland”) and sympatric (“together in the fatherland”) forms. In both cases, a single population divides into two, and heritable differences eventually prevent gene flow between the two through reproductive isolation.
