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.

Clustered Mushroom

Habitat

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

Buckelwal

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.

Clustered Mushroom

Agaricus cappellianus is a saprotrophic agaric fungus in the family Agaricaceae, the family containing the cultivated button mushroom (A. bisporus). Like other members of the genus Agaricus, A. cappellianus produces a cap with free gills that start out white or pink and darken to brown or blackish-brown as the spores mature. The stipe bears an annulus (ring) and is separate from the cap at maturity. A. cappellianus is known primarily from Europe, where it grows in grassy habitats, woodland edges, and gardens. The genus Agaricus is large, with hundreds of species globally, and field identification can be challenging. Important identification characters include cap color and texture, flesh-bruising reactions (yellowing or reddening), smell (anise-like vs. phenolic), spore color and size, and stipe characteristics. Some Agaricus species are edible and prized, while others contain phenolic compounds that cause gastrointestinal upset. Formal IUCN conservation status has not been assessed for A. cappellianus. The species has not been widely studied, and limited information is available on its ecology, host range, and distribution.
