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 Salsify

<em>Tragopogon porrifolius</em>, commonly known as common salsify, vegetable oyster, or purple salsify, is a biennial or perennial herbaceous plant in the family Asteraceae. Native to Mediterranean Europe and western Asia, it has been widely cultivated as a root vegetable since antiquity and has naturalized extensively across Europe, the Americas, Australia, and parts of Asia. The plant typically grows on roadsides, waste ground, dry grasslands, and disturbed soils in sunny locations. In its first year it produces a rosette of grass-like, grey-green leaves; in the second year it produces tall, branched stems bearing showy purple flower heads that resemble large dandelions, typically 5–7 centimeters in diameter. The edible taproot has a pale, somewhat oyster-like flavor when cooked, and the young shoots and flower buds are also edible. Common salsify is not currently evaluated on the IUCN Red List. Pollination is primarily by bees and other insects visiting the flowers, which open only in morning sunlight. Seeds are dispersed by wind via a feathery pappus. The species favors well-drained, moderately fertile soils and can be found in both rural and urban habitats. Biological traits such as average lifespan, body measurements, and detailed ecological diet data remain poorly documented in standardized ecological databases.
