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。

Chubby Grimmia

The Chubby Grimmia (Schistidium flaccidum) is a small acrocarpous moss in the family Grimmiaceae, found on acidic rock surfaces across northern Europe and Scandinavia. Despite its common name, the species belongs to the genus Schistidium rather than Grimmia, although the two genera are closely related within the family. S. flaccidum grows in compact cushion-forming tufts on siliceous boulders, cliff faces, and rocky outcrops in humid, often montane environments. The moss is documented from Norway and Sweden, where it occurs in habitats typical of boreal and subarctic rock communities. Like other Schistidium species, it produces sporophytes with exserted or immersed capsules that release spores for dispersal. The genus Schistidium is one of the largest among saxicolous (rock-dwelling) mosses, with many species distinguished by subtle differences in leaf shape, costa characteristics, and peristome structure. C. flaccidum has not been evaluated for conservation status by the IUCN and is listed as Not Evaluated. Rocky habitats support diverse bryophyte communities that are sensitive to air quality and moisture regimes. The ecology of Schistidium species on Scandinavian rock communities has been the subject of detailed phytosociological studies.
