Polar bear

Habitat

Found across multiple habitat types including temperate broadleaf and mixed forests, temperate coniferous forests, and boreal forests and taiga, among 4 distinct biome types within the Palearctic biogeographic realm. Populations are also found in montane and highland environments at higher elevations.

Range

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

Clitocybe marginella is a small agaric fungus in the family Tricholomataceae found in temperate European woodland and semi-open habitats. Like many members of the diverse Clitocybe genus, it produces modest fruiting bodies with a depressed to funnel-shaped cap and decurrent gills running down the stipe, typically whitish to pale buff in coloration. The species fruits in autumn, colonizing leaf litter, humus-rich soils, and woodland margins where it functions as a saprotrophic decomposer. The epithet marginella may reference subtle marginal features of the cap or gills that help distinguish it from closely related species. Identification within this genus typically requires microscopic examination of spore size and shape, along with assessment of odor, taste, and substrate preferences. European Clitocybe diversity is significant, with dozens of species recorded across forest, grassland, and heathland habitats. C. marginella contributes to the intricate web of decomposer fungi that recycle nutrients in temperate forest ecosystems throughout Northwestern and Central Europe.

Polar bear

지구상에서 가장 큰 육상 육식동물인 북극곰은 700kg을 넘을 수 있으며 캐나다에서 러시아까지 북극 해빙 전역에 분포한다. 고리 물범과 수염 물범을 사냥하기 위해 해빙에 의존하는 고도로 특수화된 해양 포유류이다. 광활한 거리를 헤엄쳐 다닐 수 있는 뛰어난 수영 실력을 가지고 있다. 취약종으로 등재되어 있으며, 기후 변화로 인한 급격한 북극 해빙 감소로 심각한 압력을 받고 있다.
