Habitat & Geographic Range

Clustered Bonnet

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).

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.

Clustered Bonnet

Mycena inclinata, the clustered bonnet, is a small saprotrophic fungus in the family Mycenaceae that typically grows in dense clusters at the base of oak stumps and oak logs, and occasionally on beech or other hardwoods across the northern hemisphere. The fruiting bodies are graceful, with a broadly conical to bell-shaped cap typically pale greyish-brown, darkening toward the center, and a slender, brittle stem. One distinctive feature is the finely serrated or frilly-edged (frosted) lower stipe. The gills are white, later with pinkish tints in old specimens. M. inclinata has a distinctive mealiness or rancid smell compared to some other Mycena species, and it causes white rot in its woody substrate. It is widespread and common in deciduous and mixed woodlands throughout Europe and North America, fruiting from late summer through late autumn. The clustered growth habit on oak wood is characteristic and aids identification. The genus Mycena is large, with hundreds of species globally, many requiring microscopic examination for certain identification. M. inclinata is classified as Least Concern given its abundance and wide distribution.

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.
