Habitat & Geographic Range

Blauwal

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 Toadskin Lichen

Habitat

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

Range

Distributed across Norway and United States.

Blauwal

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 Toadskin Lichen

<em>Lasallia papulosa</em>, known as the common toadskin lichen, is a foliose lichen in the family Umbilicariaceae, belonging to the broader group of rock-dwelling umbilicate lichens. This species typically grows attached to exposed siliceous rock surfaces, particularly granite, quartzite, and other acidic rock outcrops in montane, boreal, and arctic environments across North America and parts of Europe and Asia. The thallus is typically olive-brown to dark gray in color, with a distinctively blistered or pustulate upper surface texture that gives the species its common name. It attaches to the substrate by a single central holdfast (the umbilicus), allowing the irregular, lobed thallus edges to lift freely. <em>Lasallia papulosa</em> is ecologically important as a pioneer species on bare rock, contributing to weathering processes and providing microhabitat and food for specialized invertebrates. It is sensitive to air pollution, particularly sulfur dioxide, and is often used as a bioindicator of air quality. The geographic range spans rocky regions of eastern North America, Scandinavia, the Alps, and parts of northern Asia. The species is currently assessed as Least Concern by the IUCN. Biological traits such as average growth rates, thallus dimensions, and biomass estimates remain poorly documented in the scientific literature.
