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。

Clauzadea monticola is a crustose lichen in the family Lecanoromycetes, typically found growing on calcareous rock surfaces in montane and subalpine environments across Europe and parts of Asia. This saxicolous species forms tightly adherent gray to brownish thalli that merge seamlessly with the substrate, often colonizing exposed limestone, dolomite, and mortar in cold, humid climates. Its apothecia are characteristic lecideine structures with dark, often black discs and prominent thalline excipula. Like many saxicolous lichens, Clauzadea monticola plays an important ecological role in early-stage rock colonization, contributing to the gradual weathering and formation of thin soils. The species tolerates extreme temperature fluctuations and intermittent desiccation, making it well adapted to high-altitude rocky habitats. It reproduces both sexually through ascospores dispersed from apothecia and vegetatively. The precise global distribution remains incompletely documented due to the cryptic nature of lichen diversity in mountainous terrain. Taxonomic placement has been revised over time as molecular studies have refined understanding of crustose lichen phylogenetics. Conservation status is not formally evaluated, though habitat loss through quarrying and acid deposition poses potential threats to calcareous rock lichen communities. Clauzadea monticola is studied in lichenological surveys as an indicator of calcareous bedrock conditions and relatively undisturbed montane environments.
