Temporal Isolation
Temporal isolation explained in an easy to understand way:
Imagine trying to coordinate a dinner with a friend who works the night shift while you work during the day. Just as your work schedules prevent you from being able to meet for dinner, temporal isolation prevents two populations from interbreeding because they reproduce at different times. In this analogy, your and your friend's differing work hours are like the distinct breeding times of the populations, preventing your paths from crossing and thus, just like the populations, you miss the opportunity to connect.
