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。

Clavaria krieglsteineri is a rare club fungus in the family Clavariaceae, described from central European specimens and named in honor of mycologist G.J. Krieglsteiner. Like other members of the genus Clavaria, it produces simple, slender, unbranched to sparingly forked fruiting bodies, typically pale in coloration, emerging from soil in grassland or lightly wooded habitats. The morphology of Clavaria species can be difficult to distinguish without microscopic examination of spore size, shape, and basidia characters, and molecular phylogenetics has significantly reorganized the genus in recent decades. Clavaria krieglsteineri inhabits unimproved grasslands and semi-natural meadows in central Europe, ecosystems that have declined steeply under agricultural pressure. These grassland coral fungi are sensitive indicators of long-undisturbed soils and are frequently used in national biodiversity assessments as markers of ecologically valuable meadowland. The species is saprotrophic, recycling nutrients from decaying organic matter in shallow soils. Fruiting typically occurs in late summer through autumn, contingent on adequate soil moisture. As with many specialist grassland fungi, Clavaria krieglsteineri faces threats from fertilizer application, ploughing, and the conversion of ancient meadows to arable land or improved pasture. The species is listed on regional red lists in parts of central Europe and is considered rare in the localities where it has been documented.
