Habitat & Geographic Range

大翅鯨

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 (5 countries), and South America (Colombia, Ecuador, Venezuela). Currently classified as Vulnerable on the IUCN Red List, this species faces significant conservation challenges across its 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.

大翅鯨

座头鲸是大型鲸类中最具杂技表演性的物种之一，以繁殖季节雄性演唱的复杂而神秘的歌声著称，歌声有时持续数小时并随时间演变。体长可达16米，体重30吨，进行着哺乳动物中最长距离的洄游。分布于所有大洋，通过协作泡泡网捕食磷虾和小鱼。种群数量已从历史捕鲸后大体恢复。

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.
