Detailed explanation-1: -Answer: Temporal isolation happens when two or more species reproduce at different times. For example, three species of orchid live in the same rain forest.
Detailed explanation-2: -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-3: -Temporal isolation occurs when two populations differ in their periods of activity or reproductive cycles. Example: Leopard frogs and wood frogs reach sexual maturity at different times in the spring and hence cannot interbreed.
Detailed explanation-4: -One good example of temporal isolation is in the case of flowering plants. Even though two closely related species of flowering plants are located in the same area, the time of sexual maturity of one species may be different from that of the other.
Detailed explanation-5: -Temporal Isolation For example, two populations of plants may produce flowers in different seasons, making mating between the populations impossible.
