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。

Clitocybe agrestis is a small, pale agaric fungus in the family Tricholomataceae found across Western and Northern Europe, recorded from Belgium, Denmark, Norway, Portugal, and Sweden. It typically inhabits open grassy habitats including meadows, pastures, lawns, and roadsides, fruiting in autumn when moisture conditions are favorable. The cap is whitish to pale buff, often inrolled when young and becoming broadly flattened to slightly funnel-shaped with age, with crowded, decurrent gills and a short cylindrical stipe. The genus Clitocybe is characterized by the funnel-shaped or depressed cap and decurrent gill arrangement that gives many species a distinctive appearance. C. agrestis is a saprotrophic decomposer, breaking down plant litter and organic matter in grassland soils. It may be confused with toxic Clitocybe species, making accurate identification important. The species is listed as Least Concern, though European grassland fungi broadly face pressure from agricultural intensification, nitrogen deposition, and conversion of diverse meadows to monoculture pastures.
