Which is an example of temporal isolation?
A
flowers that bloom in different months
B
birds that have different mating calls
C
fruit flies that mate in different locations
D
squirrels that have different fur colors
Explanation: 

Detailed explanation-1: -Answer: Temporal isolation happens when two or more species reproduce at different times. For example, three species of orchid live in the same rain forest.

Detailed explanation-2: -Examples of temporal isolation include differences in mating behaviors or fertility due to the time of day, time of year, or varied mating cycles. Two species which are temporally isolated long enough may eventually accrue enough genetic differences that they will no longer be able to interbreed.

Detailed explanation-3: -For example, a peculiar form of temporal isolation has been observed between two closely related species of cicadas of the genus Magicicada in the United States. Sexually mature adults of Magicicada tredecim emerge every 13 years, whereas those of M. septendecim emerge every 17 years.

Detailed explanation-4: -One good example of temporal isolation is in the case of flowering plants. Even though two closely related species of flowering plants are located in the same area, the time of sexual maturity of one species may be different from that of the other.

Detailed explanation-5: -Temporal isolation:-It is the type of prezygotic isolation which is also known as habitat isolation, which is characterized by when different habitat or environmental conditions create different maturation time periods for individuals that create strong physical barriers for reproduction.
