ハクトウワシ

アメリカの国鳥であり保全の成功を象徴するハクトウワシは翼開長が最大2.4 mに達し、北米全域の水辺近くの森林や湿地に生息する。強力な空中捕食者兼腐肉食者で魚を主食とするが、水鳥や腐肉も捕食する。DDT汚染と狩猟によって1960年代にほぼ絶滅に瀕したが、農薬の使用禁止と絶滅危惧種法の施行により劇的に回復した。

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.
