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。

Dictyota dichotomは、繰り返し二叉分岐する平らなオリーブ緑色から黄褐色の葉状体が広い扇形を形成する一般的な褐藻類である。世界の温帯から熱帯の海の潮間帯や浅い潮下帯の岩礁に生息する。この光合成大型藻類は付着根を介して岩に固着し、有性生殖と無性生殖の両方が可能である。
