Question

which is an example of temporal isolation?
flowers that bloom in different months
birds that have different mating calls
fruit flies that mate in different locations
squirrels that have different fur colors

Explanation:

Temporal isolation is a pre - zygotic reproductive barrier where species breed at different times. Flowers blooming in different months is an example as it involves a time - based difference in reproductive activity. Birds with different mating calls is an example of behavioral isolation, fruit flies mating in different locations is an example of habitat isolation, and squirrels with different fur colors is not a form of reproductive isolation relevant here.

Answer:

flowers that bloom in different months
