Habitat & Geographic Range

藍鯨

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 11 distinct biome types. Populations are also found in montane and highland environments at higher elevations.

Range

Widely distributed across Asia (Taiwan), Europe (4 countries), and South America (Colombia, Ecuador). Currently classified as Vulnerable on the IUCN Red List, this species faces significant conservation challenges across its range.

Common Stump Brittlestem

Habitat

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

Range

Widely distributed across Asia (Taiwan), Europe (5 countries), North America (United States), and South America (Brazil).

藍鯨

蓝鲸是地球上已知存在过的最大动物，体长可达33米，体重达200吨，其心脏单独就重达一辆小型轿车的重量。分布于各大洋，在极地觅食地和热带繁殖地之间进行迁徙。它们是滤食性动物，每日可消耗多达4吨磷虾。蓝鲸被列为濒危物种，20世纪捕鲸活动使其濒临灭绝，目前全球种群估计约为1万至2.5万头。

Common Stump Brittlestem

<em>Psathyrella piluliformis</em>, the common stump brittlestem, is a saprotrophic basidiomycete fungus in the family Psathyrellaceae, order Agaricales. It has a broad distribution across Asia, Europe, and the Americas, typically found growing in dense clusters on or near the stumps and buried roots of deciduous trees, particularly oaks and beeches, from autumn through to early winter. The fruitbodies are hygrophanous, changing colour dramatically depending on moisture content, ranging from pale buff when dry to a rich honey-brown when wet. <em>Psathyrella piluliformis</em> plays an important ecological role as a wood decomposer, facilitating the breakdown of lignin and cellulose and contributing to nutrient cycling in forest ecosystems. The fragile, brittle gills and thin-walled spores are characteristic of the genus. Biological traits including average mycelial lifespan, fruiting body dimensions under natural conditions, and specific substrate preferences remain poorly documented. The species is assessed as Least Concern by the IUCN, reflecting its wide distribution and apparent abundance across temperate woodland habitats in the Northern Hemisphere and beyond.
