Final answer:
The coyote's range expansion since human encroachment is likely due to its adaptation to a more varied diet, enhancing its food supply and ability to thrive in changing environments.
Explanation:
The most likely reason for the coyote's range expansion since human encroachment began is that it has adapted its diet to include more variety, thereby increasing its food supply. This change in diet may have led to the coyote being able to thrive in various environments where human activities have altered traditional ecosystems. In ecosystems like Yellowstone National Park, the presence of keystone species like wolves has triggered cascading effects on biodiversity by affecting prey populations.
