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

Range

Found in Canada.

Lion

Habitat

Found across multiple habitat types including tropical and subtropical moist broadleaf forests, tropical and subtropical grasslands and savannas, and flooded grasslands and savannas, among 7 distinct biome types spanning the Afrotropic and Neotropic and Oceanian realms. Populations are also found in montane and highland environments at higher elevations.

Range

Distributed across Colombia, Ecuador, and Kenya. Currently classified as Vulnerable on the IUCN Red List, this species faces significant conservation challenges across its range.

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.

Lion

The largest wild cat in Africa, lions reach up to 250 kg and are the only social felids, living in prides across sub-Saharan savannas and grasslands. Males are distinguished by their iconic manes. As apex predators, they regulate herbivore populations and maintain ecosystem balance. Listed as Vulnerable due to habitat loss and human-wildlife conflict.
