Reproductive isolation mechanism prevent interbreeding of naturally sympatric population. Given below are categories of isolating mechanisms. Choose the correct name for isolation when potential mates occupy overlapping ranges but reproduce at different times of the year.

Ecological isolation

Behavioural isolation

Temporal isolation

Mechanical isolation

Solution

C.

Temporal isolation

Temporal isolation is an evolutionary mechanism that keeps individuals of different species from interbreeding, even if they live in the same environment. It prevents species from mating because they breed at different times. These differences can be time of day, season, or even different years. Both plants and animals may exhibit temporal isolation, even if species are closely related and live in the same habitat.
