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。

Coastal beach sandmat

Euphorbia mesembryanthemifolia, the coastal beach sandmat, is a prostrate, mat-forming succulent herb in the family Euphorbiaceae adapted to coastal sand dune and beach margins in the Caribbean basin, with native occurrences in Cuba, Colombia, and adjacent tropical American coastlines. The species is particularly well adapted to harsh coastal conditions including salt spray, intense solar radiation, shifting sands, and periodic flooding, forming low, spreading mats directly on beach sand and foredune systems. Its small, thick, succulent leaves resemble those of ice plants (Mesembryanthemum) in the family Aizoaceae, a resemblance captured in the specific epithet. Like all euphorbias, it contains a toxic milky latex that deters herbivory. The cyathia, or characteristic euphorbia pseudoflowers, attract small insects that pollinate the plants. Euphorbia mesembryanthemifolia is classified as Least Concern by the IUCN, though Caribbean coastal habitats face significant ongoing threats from sea-level rise, increased storm surge associated with intensifying hurricanes, beach tourism infrastructure development, and coastal stabilization that removes the natural dynamism these specialist plants require to persist and disperse along shorelines.
