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。

Common Bladder Moss

The common bladder moss (<em>Physcomitrium pyriforme</em>) is a small annual moss belonging to the family Funariaceae. It is classified as Least Concern on the IUCN Red List and is native to Europe and North America, with confirmed records from Luxembourg, Portugal, and the United States. <em>Physcomitrium pyriforme</em> typically colonizes disturbed, moist soils such as cultivated fields, riverbanks, and pond margins, where it forms low-growing green mats or cushions. The species is an ephemeral moss, completing its life cycle rapidly after disturbance events that expose bare soil. It is recognizable by its pear-shaped or inflated capsules borne on short setae, which give the species its common name. Spores are dispersed through the splitting of the capsule lid, and the plant often takes advantage of temporarily wet conditions for growth and reproduction. Biological traits of this species remain poorly documented in the scientific literature.
