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.

Achnanthes armillaris is a small, monoraphid diatom in the family Achnanthidiaceae, attached to submerged substrates by a mucilage pad at one pole of its frustule. It inhabits freshwater streams, rivers, and lakes, forming part of the epilithic and epiphytic diatom community. Like other Achnanthes species, it serves as a bioindicator for water chemistry and flow regime in freshwater monitoring programs.

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.
