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 Ground-Pine

The common ground pine, <em>Dendrolycopodium obscurum</em>, is a vascular plant belonging to the family Lycopodiaceae, a lineage of ancient clubmosses. This species is typically found across North America, with its known range encompassing Canada and the United States. As a lycophyte, <em>Dendrolycopodium obscurum</em> represents a deeply divergent lineage among land plants, distinct from mosses and ferns. The species typically grows in moist forested habitats, particularly in coniferous and mixed woodlands where humidity and leaf litter provide suitable conditions for its growth. Its upright, tree-like sporophylls give it the common name ground pine. No dietary information has been provided for this species. Biological traits of this species remain poorly documented in the scientific literature.
