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。

Colonial Pine

Araucaria cunninghamii, the colonial pine or hoop pine, is a large coniferous tree in the ancient family Araucariaceae, native to Australia and also cultivated or naturalised in India, Libya, and South Africa. This species inhabits temperate and boreal forests at higher elevations, where it often forms a prominent emergent layer in subtropical and tropical rainforest communities in Queensland and New Guinea. Hoop pine is one of Australia's most commercially important softwood timber species, valued for its straight grain, durability, and workability. Trees can grow to considerable heights, with tall trunks characterised by horizontally spreading branch whorls that give the species a distinctive silhouette. Araucaria cunninghamii is assessed as Least Concern by the IUCN. The genus Araucaria has ancient origins, with fossil records extending to the Jurassic period, making it a living relic of Gondwanan flora. Seeds of hoop pine are consumed by birds and other fauna in its native range, contributing to limited seed dispersal. Biological traits of this species remain poorly documented in the scientific literature.
