giraffe

Habitat

Found across multiple habitat types including tropical and subtropical moist broadleaf forests, tropical and subtropical dry broadleaf forests, and flooded grasslands and savannas, among 5 distinct biome types within the Neotropic biogeographic realm. Populations are also found in montane and highland environments at higher elevations.

Range

Found in Ecuador. Currently classified as Vulnerable on the IUCN Red List, this species faces significant conservation challenges across its range.

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.

giraffe

长颈鹿（Giraffa camelopardalis）是地球上最高的动物，身高可达5.5米，体重最重可达1,750千克。其细长的颈部——与所有哺乳动物一样包含七块颈椎——是为了在非洲稀树草原和林地取食金合欢树而进化的。长颈鹿是社会性动物，生活在无固定纽带的松散兽群中，通过次声波和肢体语言进行交流。由于栖息地丧失和偷猎，种群持续减少，被列为易危。
