Range

Found across Europe (6 countries). Listed as Near Threatened, this species requires ongoing monitoring to prevent population decline.

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。

Clustered Feather-moss

Rhynchostegium confertum, the clustered feather moss, is a pleurocarpous moss in the family Brachytheciaceae distributed across Europe, where it grows on rocks, walls, tree bases, and compacted soil in a variety of habitats including woodland, gardens, churchyards, and urban environments. The plants form dense, bright green to yellowish-green mats with pinnately branched stems bearing small, ovate-lanceolate leaves. This species is listed as Near Threatened by the IUCN, reflecting concerns about population declines in parts of its European range, possibly related to air quality changes, habitat alteration, and drought. Brachytheciaceae mosses are common components of temperate and boreal flora, and R. confertum is one of the more urban-tolerant members of the family, occurring even in heavily built environments. Like all pleurocarpous mosses, R. confertum spreads vegetatively through fragmentation and produces spores from upright, slender sporophytes during the reproductive season. It contributes to moisture retention on substrates and provides microhabitats for invertebrates in urban and semi-natural environments.
