Habitat & Geographic Range

Buckelwal

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 (5 countries), and South America (Colombia, Ecuador, Venezuela). Currently classified as Vulnerable on the IUCN Red List, this species faces significant conservation challenges across its range.

Habitat

Typically found in forest floors, decomposing wood, and soil ecosystems.

Range

Distributed across Belgium, Denmark, Norway, and Sweden.

Among the most acrobatic of the great whales, humpback whales are renowned for their complex, haunting songs sung by males during breeding season — some lasting hours and evolving over time. Reaching 16 meters and 30 tonnes, they undertake the longest migrations of any mammal. Found in all oceans, humpbacks feed on krill and small fish using cooperative bubble-net feeding. Populations have largely recovered from historic whaling.

Clitocybe amarescens is a small, bitter-tasting agaric fungus in the family Tricholomataceae distributed across Northwestern and Northern Europe, with confirmed records from Belgium, Denmark, Norway, and Sweden. The specific epithet amarescens reflects the notably bitter flavor of the fruiting bodies, a characteristic that distinguishes it from some closely related Clitocybe species. The cap is typically whitish to pale greyish, smooth, with decurrent gills characteristic of the genus, and fruits in woodland margins, grassy clearings, and other semi-open habitats during autumn months. Like other Clitocybe species, it is a saprotrophic fungus contributing to decomposition of leaf litter and organic debris. The bitter taste likely serves as a deterrent against invertebrate predation. The species is assessed as Least Concern across its European range but, like other fungi of unimproved grasslands and forest margins, remains potentially sensitive to habitat changes driven by agricultural intensification, fertilizer application, and loss of structurally diverse woodland edges across Scandinavia and Western Europe.
