Habitat & Geographic Range

blue whale

Habitat

Found across multiple habitat types including tropical and subtropical moist broadleaf forests, tropical and subtropical dry broadleaf forests, and tropical and subtropical grasslands and savannas, among 11 distinct biome types. Populations are also found in montane and highland environments at higher elevations.

Range

Widely distributed across Asia (Taiwan), Europe (4 countries), and South America (Colombia, Ecuador). Currently classified as Vulnerable on the IUCN Red List, this species faces significant conservation challenges across its range.

Columbia sedge

Habitat

Typically found in grasslands, wetlands, forests, and cultivated landscapes.

Range

Found in Canada.

blue whale

The largest animal ever known to have lived on Earth, blue whales can reach 33 meters and 200 tonnes — their hearts alone weigh as much as a small car. Found in all oceans, they migrate between polar feeding grounds and tropical breeding areas. Filter feeders consuming up to 4 tonnes of krill daily. Endangered, with global populations estimated at 10,000–25,000 after near-extinction from 20th-century whaling.

Columbia sedge

<em>Carex aperta</em>, the Columbia sedge, is a perennial sedge in the family Cyperaceae native to Canada, where it occurs in grasslands, wetlands, riparian forests, and cultivated landscapes. This species is assessed as Least Concern by the IUCN. Columbia sedge typically inhabits moist to wet habitats including stream banks, lake shores, and seasonally flooded meadows within its Canadian range, where it often forms part of the emergent or shoreline vegetation community. Like other members of the genus <em>Carex</em>, this species is wind-pollinated and produces small, nut-like fruits enclosed within specialised sac-like structures called perigynia, features that facilitate taxonomic identification. Sedges in riparian and wetland ecosystems perform important ecological functions including bank stabilisation through rhizome networks, provision of nesting material and cover for waterfowl and small mammals, and contribution to organic matter accumulation in wetland soils. <em>Carex aperta</em> is adapted to fine-textured, moisture-retentive soils and may tolerate seasonal inundation. Its distribution in Canada spans portions of British Columbia and adjacent provinces within moist temperate forest zones. Biological traits of this species remain poorly documented in the scientific literature.
