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.

Habitat

Native to Europe, inhabiting ecosystems characteristic of the region.

Range

Distributed across Denmark, Norway, and Sweden. Listed as Near Threatened, this species requires ongoing monitoring to prevent population decline.

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.

Clauzadea monticola is a crustose lichen in the family Lecanoromycetes, typically found growing on calcareous rock surfaces in montane and subalpine environments across Europe and parts of Asia. This saxicolous species forms tightly adherent gray to brownish thalli that merge seamlessly with the substrate, often colonizing exposed limestone, dolomite, and mortar in cold, humid climates. Its apothecia are characteristic lecideine structures with dark, often black discs and prominent thalline excipula. Like many saxicolous lichens, Clauzadea monticola plays an important ecological role in early-stage rock colonization, contributing to the gradual weathering and formation of thin soils. The species tolerates extreme temperature fluctuations and intermittent desiccation, making it well adapted to high-altitude rocky habitats. It reproduces both sexually through ascospores dispersed from apothecia and vegetatively. The precise global distribution remains incompletely documented due to the cryptic nature of lichen diversity in mountainous terrain. Taxonomic placement has been revised over time as molecular studies have refined understanding of crustose lichen phylogenetics. Conservation status is not formally evaluated, though habitat loss through quarrying and acid deposition poses potential threats to calcareous rock lichen communities. Clauzadea monticola is studied in lichenological surveys as an indicator of calcareous bedrock conditions and relatively undisturbed montane environments.
