Which reproductive isolation occurs when the mating schedules of species do not align?

Temporal isolation is a form of reproductive isolation that occurs when different species breed at different times, which prevents them from mating even if they live in the same area. This could manifest in different mating behaviors, seasonal breeding, or even differences in circadian rhythms that affect when species are active. For example, one species may reproduce in the spring while another species reproduces in the fall, thus reinforcing their separation despite potential overlapping habitats.

This form of isolation is crucial in preventing gene flow between populations, allowing them to evolve independently over time. It helps maintain the distinct characteristics of each species, which is essential for the process of speciation.
