By concentrating nutrients on dens Arctic foxes enhance nutrient cycling as an ecosystem service and thus engineer Arctic ecosystems on local scales. The enhanced productivity in patches on the landscape could subsequently affect plant diversity and the dispersion of herbivores on the tundra.
What would happen if arctic foxes became extinct?
If the arctic fox became extinct, it would alter the ecosystem of the arctic regions where they live.

Their muzzle, ears, and legs are short, which also conserves heat. … Arctic foxes also have thick fur on their paws, which allows them to walk on both snow and ice.
Why are Arctic fox keystone species?
The Arctic fox is a keystone species because it is the main food source of polar bears, wolves, and kittiwakes. The decline of the Arctic fox would greatly impact the survival of these predators. … The Arctic fox helps balance these populations so that they do not grow out of control.
