Habitat & Geographic Range

Habitat

Native to Europe, inhabiting ecosystems characteristic of the region.

Range

Distributed across Denmark, Norway, and Sweden. Currently classified as Vulnerable on the IUCN Red List, this species faces significant conservation challenges across its range.

Epaulard

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, Venezuela).

Choiromyces venosus, commonly known as the White Truffle of Finland or the Pig Truffle, is a subterranean (hypogeous) ascomycete fungus in the family Tuberaceae, found in temperate forests of northern and central Europe, extending into Scandinavia. Like the more prized Italian white truffle (Tuber magnatum), it is an ectomycorrhizal fungus, forming symbiotic associations with the roots of forest trees including birch, oak, pine, and spruce. The fruiting bodies develop entirely underground or just at the soil surface, reaching up to 15 centimetres in diameter, with a whitish to cream-coloured, irregularly lobed surface and a marbled interior reminiscent of true truffles. While not as commercially valuable as Tuber species, C. venosus is harvested in parts of Scandinavia and northern Europe and is used in cooking — although it requires preparation as the raw fungus contains volatile compounds that are toxic if consumed in quantity. The IUCN classifies this species as Vulnerable in parts of its range, reflecting declines in habitat quality associated with changes in forest management, nitrogen deposition, and soil disturbance. Monitoring hypogeous fungal populations is inherently difficult, as fruiting bodies are invisible until they emerge and the mycelial network underground cannot be easily surveyed.

Epaulard

O maior membro da família dos golfinhos, as orcas (Orcinus orca) podem atingir até 9 metros de comprimento e 6 toneladas, sendo encontradas em todos os oceanos, do Ártico ao Antártico. Predadores de topo que vivem em grupos matrilineares com dialetos distintos, estratégias de caça e tradições culturais que diferem entre populações. Algumas populações se especializam em peixes, outras em mamíferos marinhos. Sem predadores naturais, as orcas ocupam o topo de todas as cadeias alimentares marinhas que habitam.
