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。

Chaetoceros minimusはChaetocerota科の小型海産浮遊珪藻類で、各細胞の角から伸びる長い剛毛が特徴だ。属内で最も小さい種の一つで、沿岸および外洋水域に広く分布し海洋一次生産に大きく貢献する。他の糸状突起珪藻類と同様に鎖状群体を形成でき、海底への炭素輸出に重要な役割を果たす。
