Ours brun

The world's most widely distributed bear species, brown bears range from North America and Europe across Russia to Japan, occupying forests, tundra, and alpine meadows. Adults can weigh up to 700 kg in coastal Alaskan populations. Omnivores that consume berries, roots, fish, and carrion, brown bears are a keystone species that distribute nutrients across landscapes. Most populations are stable, though some subspecies are threatened.

loup

The most widely distributed wild canid, gray wolves range from North America across Eurasia in diverse habitats including tundra, forests, and grasslands. Highly social animals living in family packs led by a dominant breeding pair. As keystone predators, wolves regulate prey populations and profoundly shape ecosystem structure, as demonstrated by their reintroduction in Yellowstone. Once heavily persecuted, populations are recovering in many regions.
