Habitat & Geographic Range

白头海雕

Habitat

Found across multiple habitat types including tropical and subtropical moist broadleaf forests, tropical and subtropical dry broadleaf forests, and flooded grasslands and savannas, among 10 distinct biome types spanning the Neotropic and Palearctic realms. Populations are also found in montane and highland environments at higher elevations.

Range

Widely distributed across Europe (8 countries), North America (United States), and South America (Ecuador).

Clouded Agaric

Habitat

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

Range

Distributed across Belgium, Norway, Sweden, Taiwan, and United States.

白头海雕

白头海雕是美国国鸟，也是美国生态保护史上的成功案例，曾因滴滴涕（DDT）的广泛使用而濒临灭绝，经保护措施的实施后种群数量已显著恢复。该物种在IUCN红色名录中被评估为无危（LC），以白色头颈和尾羽与深棕色体羽形成的鲜明对比为主要识别特征。它们主要以鱼类为食，也会捕食哺乳动物和腐肉。

Clouded Agaric

The clouded agaric (Clitocybe nebularis, syn. Lepista nebularis) is a large, robust saprotrophic mushroom in the family Tricholomataceae found across temperate broadleaved and mixed forests of Europe and North America. It produces pale grey to buff fruiting bodies with broad, wavy caps up to 20 cm diameter, crowded, slightly decurrent gills, and a stout stipe, typically emerging in large fairy rings or scattered groups in autumn woodland settings. The common name 'clouded' refers to the greyish, misty coloration of the cap surface. Though historically eaten in parts of Europe and considered edible when thoroughly cooked, C. nebularis is now known to contain toxic compounds and a heat-labile gastrointestinal toxin that causes illness in some individuals, and it is associated with documented poisoning cases. Its strong mealy odor is distinctive. The species is widespread and common across European deciduous forests, fruiting reliably in autumn and forming an important component of the saprotrophic fungal community responsible for decomposing accumulated leaf litter and organic matter in temperate forest ecosystems.
