Habitat & Geographic Range

Clustered Sedge

Habitat

Inhabits boreal forests and taiga within the Palearctic biogeographic realm. Populations are also found in montane and highland environments at higher elevations.

Range

Distributed across Finland, Iceland, Norway, and Sweden. Currently classified as Vulnerable on the IUCN Red List, this species faces significant conservation challenges across its range.

Epaulard

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, Venezuela).

Clustered Sedge

Carex glareosa, the clustered sedge or gravel sedge, is a perennial sedge in the family Cyperaceae distributed across the circumpolar Arctic and subarctic zones of the northern hemisphere, growing in coastal and inland wetlands, salt marshes, brackish meadows, mudflats, gravelly tundra, and low-lying areas subject to periodic flooding. The species forms dense tufts or loose colonies, producing narrow, grass-like leaves and small spikelets characteristic of the genus Carex. C. glareosa is adapted to saline and brackish conditions in coastal habitats, as well as to freshwater wetlands in more continental settings. Like other Arctic sedges, it is an important component of tundra and wetland plant communities that provide habitat and forage for migratory waterfowl, shorebirds, and Arctic mammals. The species is listed as Vulnerable by the IUCN, with concern focused on the impacts of climate change on Arctic and subarctic wetland habitats, where rising temperatures, permafrost thaw, altered hydrology, and increased shrub encroachment threaten specialized wetland plant communities.

Epaulard

イルカ科で最大の種であるシャチ（Orcinus orca）は体長最大9メートル、体重6トンに達し、北極から南極まですべての海洋に生息しています。独特の方言、狩猟戦略、集団間で異なる文化的伝統を持つ母系ポッドで生活する頂点捕食者です。一部の集団は魚類を、他の集団は海洋哺乳類を専門に捕食します。天敵はなく、シャチは生息するすべての海洋食物連鎖の頂点に位置します。
