In Missouri, the marbled salamander breeds in late fall (October-December). In the same region, the closely related spotted salamander breeds in early spring (February-March). Thus, these species are kept separate because of:
temporal isolation. structural isolation. geographic isolation. behavioral isolation.
The separation of the marbled salamander and the spotted salamander due to their different breeding times is an example of temporal isolation. This type of isolation occurs when two species breed at different times, preventing them from mating even if they are in the
