One species of plant produces flowers when nights are 10 hours long. A related species comes into flower when nights are 9 hours long. What type of reproductive isolation would include this example?

Question

This example is an example of temporal isolation, which is a type of reproductive isolation where species reproduce at different times, often due to differences in seasonal or daily rhythms. In this case, the two species have different critical night lengths for flowering, which means they are unlikely to reproduce with one another because they flower at different times.
