Lobo gris

El lobo gris (Canis lupus), el cánido silvestre más ampliamente distribuido, se extiende desde América del Norte a través de Eurasia en hábitats diversos que incluyen la tundra, bosques y praderas. Son animales altamente sociales que viven en manadas familiares lideradas por una pareja reproductora dominante. Como depredadores clave, los lobos regulan las poblaciones de presas y moldean profundamente la estructura del ecosistema, como demostró su reintroducción en Yellowstone. Antes muy perseguidos, las poblaciones se están recuperando en muchas regiones.
