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.

jaguar

アメリカ大陸最大のネコ科動物で、体重は最大100kgに達し、がっしりとした筋肉質の体型と特有のロゼット模様の毛皮を持つ。メキシコから南アメリカにかけて分布し、アマゾンやパンタナルが主要生息地となる。優れた水泳能力を持つ頂点捕食者であり、獲物個体数の調節に重要な役割を担う。森林破壊により生息域が縮小し、準絶滅危惧に分類されている。
