Answer:
B) Because of habitat fragmentation and alteration, the individual populations of these SkyIslands have less genetic diversity than they did in the past.
Step-by-step explanation:
Habitat fragmentation is a process in which an organism's environment is altered, causing population fragmentation and ecosystem decay. In this example, the environment that would be affected would be the "sky lands" of western North America. As a result of these alterations, many animals would suffer a loss in population. This would particularly affect the large predators that live in these, such as mountain lions and bears, as they need large territories. As more specimens die, the populations would have less genetic diversity than they did in the past.
