Arctic foxes (Vulpes lagopus) impact their habitats in several ways:
- Prey regulation: They control lemming and vole populations, indirectly affecting plant communities.
- Scavenging: They feed on carcasses, helping recycle nutrients into the food web.
- Seed dispersal: They spread seeds of crowberries, blueberries, and Arctic raspberries through their feces.
- Denning behavior: Their dens provide shelter for other species, including ground squirrels, snowy owls, and seabirds.
- Population dynamics: Fluctuations in fox numbers affect lemming populations and plant communities, influencing the broader ecosystem.
- Disease transmission: They can carry rabies and canine distemper, affecting other carnivores and domestic dogs.
Maintaining healthy Arctic fox populations supports Arctic biodiversity and ecosystem resilience.
