Failure of organisms to become simultaneously receptive to mating, often as distinguished in terms of times of the year.
Temporal isolation is a prezygotic barrier to reproduction and one that has a genetic component. Two species can avoid hybridization if they don't mate that the same time. For example, this could be two species of flowering plants that don't produce flowers at the same time.
Temporal isolation can be an effective means by which two or more species can avoid substantial amounts of interspecific crossing.
