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.

Common Nodding Moss

Habitat

Native to Asia and Europe and North America, inhabiting ecosystems characteristic of the region.

Range

Widely distributed across Asia (Taiwan), Europe (6 countries), North America (United States), and South America (Brazil, Colombia).

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.

Common Nodding Moss

<em>Pohlia nutans</em>, the common nodding moss, is a widespread pleurocarpous moss in the family Mniaceae found across boreal, temperate, and arctic regions of the world. The species is named for the characteristic drooping, nodding posture of its capsules when mature. <em>Pohlia nutans</em> typically colonizes acidic substrates including peat, heathland soils, rotting logs, and rocky outcrops in boreal and montane environments, and is particularly common in disturbed or open habitats. Its geographic range is extensive, spanning Europe, Asia, North America, and South America, reflecting its ecological versatility and tolerance of a wide range of moisture and temperature conditions. The species is currently assessed as Least Concern by the IUCN. Biological traits such as lifespan, body size, and diet remain poorly documented for this species beyond its known autotrophic lifestyle. Like all mosses, <em>Pohlia nutans</em> reproduces through spores released from its stalked capsules and through vegetative propagation. It plays a modest but consistent role in moisture retention, soil stabilization, and early colonization of disturbed substrates across the boreal and temperate zones of multiple continents.
