The leopard frog and the pickerel frog are two closely related species. in areas where their ranges overlap, the frogs will remain separate species if they a) maintain different colored markings on their skin. b) eat different types of insects and crustaceans. c) occupy burrows in different parts of a creek. d) reproduce at different times of the year.

Ans.

The closely related species that share a same habitat or having overlapping ranges are prevented from interbreeding by reproductive isolation. The mechanisms for isolation include various behavioral, mechanical, and physiological processes. In leopard frog and pickerel frog showing overlapping ranges, temporal isolation occurs, in which closely related species show different mating seasons.

Hence, the correct answer is option 'D). reproduce at different times of the year.'
