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.

Coal Brittlegill

Habitat

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

Range

Distributed across Belgium, Denmark, Norway, and Sweden. Listed as Near Threatened, this species requires ongoing monitoring to prevent population decline.

地球上で生きたことが知られている最大の動物であるシロナガスクジラ（Balaenoptera musculus）は、体長33メートル、体重200トンに達することができ、心臓だけで小型自動車ほどの重さがあります。全ての海洋に生息し、極地の餌場と熱帯の繁殖地の間を回遊します。1日最大4トンのオキアミを摂取する濾過摂食者です。20世紀の捕鯨による絶滅危機からの回復後、世界的な個体数は10,000〜25,000頭と推定される絶滅危惧種です。

Coal Brittlegill

Russula anthracina, the coal brittlegill, is an ectomycorrhizal mushroom in the family Russulaceae associated with deciduous and mixed forests across Europe. The species forms underground mycorrhizal partnerships with hardwood trees, particularly oaks and beeches, trading mineral nutrients and water for photosynthate and representing an essential component of forest nutrient cycling. The fruiting body is characterized by a dark, charcoal grey to blackish-brown cap up to 10 centimeters across with a slightly viscid surface when moist, firm white gills, and a stout white stem. Like all brittlegills in the genus Russula, the flesh is brittle due to the presence of spherocytes rather than the interwoven hyphae that give most mushrooms their fibrous texture. Russula anthracina is confirmed from northern and central Europe including Belgium, Denmark, Norway, and Sweden, occupying mature beech-oak forest habitats. It is assessed as Near Threatened by the IUCN, reflecting declines associated with the loss and fragmentation of old-growth deciduous forest across Europe, atmospheric nitrogen deposition that disrupts mycorrhizal networks, and reduced dead wood availability. The genus Russula comprises several hundred species worldwide, making accurate species identification challenging, and population trends for specific taxa like R. anthracina are difficult to estimate with precision.
