Habitat & Geographic Range

Chocolate Milky

Habitat

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

Range

Widely distributed across Asia (Taiwan), Europe (4 countries), and North America (United States). Currently classified as Endangered on the IUCN Red List, this species faces significant conservation challenges across its range.

jaguar

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 6 distinct biome types spanning the Neotropic and Oceanian realms. Populations are also found in montane and highland environments at higher elevations.

Range

Distributed across Colombia, Ecuador, and Venezuela. Listed as Near Threatened, this species requires ongoing monitoring to prevent population decline.

Chocolate Milky

The Chocolate Milky (Lactarius lignyotus) is a medium-sized ectomycorrhizal mushroom in the family Russulaceae, found in coniferous and mixed forests across Europe, North America, and temperate Asia. Like all members of the genus Lactarius, it exudes a milky latex when the flesh is broken — in L. lignyotus, this latex is white and acrid, contributing to the genus's widespread edibility variation. The fruiting body features a distinctive dark chocolate-brown to sooty-brown, velvety cap with a central boss (umbo), similarly coloured gills, and a dark brown stipe, making it relatively recognisable among forest mushrooms. It grows in close association with spruce (Picea) and fir (Abies) trees, forming ectomycorrhizal symbioses in which the fungal mycelium envelopes root tips and exchanges mineral nutrients for plant photosynthates, a relationship fundamental to the health of boreal and montane conifer forests. The IUCN classifies the chocolate milky as Endangered in certain regional assessments, reflecting declines in suitable habitat quality linked to changes in forest management, nitrogen deposition from atmospheric pollution, and climate change affecting the timing and abundance of fruiting. Accurate population monitoring of ectomycorrhizal fungi is challenging given that the fungal organism itself is largely subterranean, visible only when fruiting.

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。
