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。

Christmas-cheer

Christmas cheer (Sedum rubrotinctum) is a succulent perennial in the family Crassulaceae, native to Mexico, though its exact wild origin is somewhat uncertain as it may be a stabilized hybrid or cultivated selection derived from closely related species in the genus Sedum. It is widely grown as an ornamental houseplant and garden succulent for its distinctive plump, jelly-bean-shaped leaves that are normally green but turn vivid red when stressed by bright light, drought, or temperature fluctuations. This color change results from the accumulation of anthocyanin pigments in response to environmental stress. The small, star-shaped yellow flowers appear in early spring on short upright stems. Sedum rubrotinctum is a frost-tender species that thrives in warm, dry conditions with well-drained soils and bright sunlight. It propagates readily from leaf cuttings, making it popular among succulent enthusiasts. The plant belongs to the large and diverse Crassulaceae family, which includes many drought-tolerant succulents adapted to arid and semi-arid environments worldwide. As a cultivated species of uncertain wild status, its conservation needs differ from those of wild-collected species, though sustainable horticultural propagation reduces pressure on related wild populations.
