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.

Common Cotton-Grass

Habitat

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

Range

Found across Europe (6 countries) and North America (United States). Currently classified as Vulnerable on the IUCN Red List, this species faces significant conservation challenges across its range.

Buckelwal

Among the most acrobatic of the great whales, humpback whales are renowned for their complex, haunting songs sung by males during breeding season — some lasting hours and evolving over time. Reaching 16 meters and 30 tonnes, they undertake the longest migrations of any mammal. Found in all oceans, humpbacks feed on krill and small fish using cooperative bubble-net feeding. Populations have largely recovered from historic whaling.

Common Cotton-Grass

<em>Eriophorum angustifolium</em>, commonly known as common cotton grass or many-stalked cottongrass, is a perennial sedge in the family Cyperaceae. It is distributed across peatlands, bogs, fens, and wet moorlands of Europe and North America, where it is often a dominant and ecologically significant species. Common cotton grass is easily recognized by its distinctive fluffy white seed heads, which resemble balls of cotton and appear conspicuously across boggy landscapes in late spring and summer. These cotton-like structures are modified perianth bristles that aid in wind dispersal of seeds. The species plays a vital role in peatland ecosystems as a peat-forming plant and provides food and nesting material for various wetland birds. It is assessed as Vulnerable on the IUCN Red List, reflecting ongoing habitat loss due to peatland drainage, agricultural conversion, and climate change. Biological traits of this species remain poorly documented in the scientific literature.
