Cinnabar Powdercap

Cinnabar powdercap (Cystodermella cinnabarina) is a small agaric fungus in the family Agaricaceae, distributed across the Northern Hemisphere in Europe, North America, and parts of Asia. It grows in woodland and forest floor habitats, particularly in needle or mixed leaf litter under conifers and mixed deciduous trees. The fruiting bodies are small to medium mushrooms with a granular, powdery cap surface in shades of orange-red to cinnabar or brick red, which gives the species its name. The gills are white and the stipe has a granular surface below the annulus (ring), typical of the genus. Cystodermella cinnabarina is classified as Vulnerable, reflecting declines linked to eutrophication, changes in forest floor conditions, and the loss of traditional forest management practices that maintained suitable microhabitats. The species is associated with relatively undisturbed, low-nutrient woodland soil conditions and is sensitive to nitrogen enrichment, which promotes competitive vegetation that degrades its habitat. Molecular phylogenetics has clarified its placement within Agaricaceae, separating it from the related genus Cystoderma. The cinnabar powdercap is an indicator of woodland fungi diversity and habitat quality. Conservation of low-intensity managed forest with diverse floor conditions benefits this and related saprotrophic macrofungi.

Polar bear

北极熊是地球上最大的陆地食肉动物，体重可超过700千克，分布于从加拿大到俄罗斯的北极海冰区。是高度特化的海洋哺乳动物，依赖海冰捕猎环斑海豹和髯海豹。是优秀的游泳者，能够横渡广阔的开阔水域。被列为易危种，因气候变化导致北极海冰迅速减少，种群正受到严重威胁。
