2. (22 points) A critically endangered salamander species (abbreviated Rs) is now confined to two isolated populations after replacement of much of its pine forest habitat by commercial pine plantations, and other factors like habitat fragmentation, fire suppression, introduced fish, and roads reduced the quality of remaining habitat. Patterns of genetic variation were compared to several more common closely related species (Rc and Ra) with similar life history and ecological traits. Review the provided data to describe and explain the...
