Distributed across Belgium, Denmark, Norway, and Sweden.

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 subcordispora is a saprotrophic agaric fungus in the family Tricholomataceae, with the species epithet subcordispora likely referencing slightly heart-shaped or cordiform spores observed under microscopy, a feature useful in distinguishing it from other pale Clitocybe species. It inhabits temperate European forest floors, woodland margins, and grassy clearings, fruiting in autumn among leaf litter and humus. The fruiting body presents the characteristic Clitocybe form with a depressed to funnel-shaped pale cap, decurrent gills, and cylindrical stipe. Spore morphology is an important taxonomic character within this genus, and the slightly cordiform spore outline of C. subcordispora may reflect adaptation to specific dispersal modes or represent a plesiomorphic character within the clade. The species contributes to saprotrophic fungal diversity in European temperate forests, where dozens of Clitocybe species occupy slightly different ecological niches in the decomposition of leaf litter, woody debris, and soil organic matter, collectively driving the nutrient cycling processes essential to forest ecosystem function.

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.
