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.

Concentric Pelt Lichen

Habitat

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

Range

Distributed across Norway, Sweden, and United States.

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.

Concentric Pelt Lichen

<em>Peltigera elisabethae</em>, commonly known as the Concentric Pelt Lichen, is a foliose lichen in the family Peltigeraceae, characterised by large, lobed thalli with a distinctive patterned upper surface and pale, veined undersides. Members of the genus Peltigera typically form symbiotic associations with either green algae or cyanobacteria (primarily Nostoc), the latter of which contributes nitrogen fixation capacity, making these lichens important contributors to nutrient cycling in boreal and tundra ecosystems. <em>Peltigera elisabethae</em> typically grows on soil, mossy rocks, tree bases, and forest floor litter in humid, cool-temperate to boreal habitats, and has been recorded in Norway, Sweden, and the United States, suggesting a circumpolar or widespread Northern Hemisphere distribution. The species has not been evaluated by the IUCN, so its formal conservation status remains unknown. Foliose Peltigera lichens generally thrive in habitats with clean air, as they are sensitive to atmospheric nitrogen deposition and sulfur dioxide pollution, making them useful bioindicators of air quality. Biological traits including thallus growth rates, individual longevity, and reproductive biology remain poorly documented for this particular species, though members of the genus are typically slow-growing, perennial organisms capable of persisting for decades on stable substrates.
