Naddik [55]

Answer:

The Monterey pine and the Bishop's pine inhabit some of the same areas of central California. The Monterey pine releases pollen in February, while the Bishop's pine does so in April. This is an example of <u>temporal</u> isolation.

<u>For example:</u> Northern america leapord frog mates in April and North America Bullfrog mates in july.

As in the given scenario, reproductive isolation is occuring in which two species (Monterey pine and Bishop's pine) are reproducing (producing pollens) at two separate times(February and April). Hence it is an example of temporal isolation.
