Habitat & Geographic Range

gray wolf

Habitat

Found across multiple habitat types including tropical and subtropical moist broadleaf forests, deserts and xeric shrublands, and tropical and subtropical dry broadleaf forests, among 13 distinct biome types. Populations are also found in montane and highland environments at higher elevations.

Range

Widely distributed across Africa (Seychelles), Asia (Japan), Europe (5 countries), North America (7 countries), Oceania and the Pacific (Marshall Islands, Vanuatu), and South America (5 countries). Currently classified as Critically Endangered on the IUCN Red List, this species faces significant conservation challenges across its range.

house mouse

Habitat

Found across multiple habitat types including tropical and subtropical moist broadleaf forests, tropical and subtropical dry broadleaf forests, and flooded grasslands and savannas, among 8 distinct biome types. Populations are also found in montane and highland environments at higher elevations.

Range

Widely distributed across Africa (9 countries), Asia (13 countries), Europe (41 countries), North America (14 countries), Oceania and the Pacific (12 countries), and South America (10 countries).

gray wolf

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.

house mouse

Among the most widespread and numerous mammals on Earth, house mice originated in South Asia and have accompanied human civilization across every continent except Antarctica. Weighing just 15–25 g, they are highly adaptable omnivores capable of surviving on minimal food and water. As the world's most commonly used laboratory animal, the house mouse has contributed to virtually every branch of biomedical research. They cause significant agricultural damage globally.
