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.

ciliate fringewort

Habitat

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

Range

Found across Europe (5 countries) and North America (United States). Currently classified as Endangered on the IUCN Red List, this species faces significant conservation challenges across its range.

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.

ciliate fringewort

Ciliate fringewort (Ptilidium ciliare) is a leafy liverwort in the family Ptilidiaceae, found in boreal and montane regions of the Northern Hemisphere, including Europe, North America, and parts of northern Asia. It grows as a creeping, irregularly branched mat with leaves divided into deeply fringed lobes edged with long, hair-like cilia—the characteristic feature that gives the species its common name. Ciliate fringewort colonizes a variety of substrates including rock surfaces, boulders, tree trunks, and peaty ground in open to moderately shaded habitats such as heathland, moorland, montane grasslands, and subalpine and subarctic vegetation. It is particularly common on exposed rocks in boreal and tundra zones. The species is classified as Endangered in parts of Europe, where lowland populations have declined severely due to atmospheric nitrogen deposition, afforestation of open heathland, and the loss of traditionally managed heath and moorland habitats. Populations in montane and boreal zones remain more stable. Ciliate fringewort is sensitive to elevated nitrogen levels that promote the competitive dominance of grasses and mosses. Restoration of lowland heathland and reduction of nitrogen pollution are key measures needed to support remaining European populations. The species is better represented in Scandinavian boreal habitats and North American taiga and tundra.
