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。

Chroomonas vectensis is a species of cryptophyte alga in the family Chroomonadaceae, with the specific epithet vectensis suggesting a type locality or particularly strong association with the Isle of Wight (Vectis in Latin), off the southern coast of England. If correctly attributed, this would place the type collection in the coastal or brackish waters of the Isle of Wight or surrounding seas, suggesting this species may be adapted to marine or brackish conditions, as opposed to the strictly freshwater Chroomonas species. Marine cryptophytes are significant contributors to coastal phytoplankton and are important prey items in marine food webs. Chroomonas vectensis would share the general characteristics of the genus — small biflagellate unicells with a cryptophyte plastid bearing phycobiliproteins and chlorophyll a and c — while potentially possessing adaptations to saline or brackish conditions such as osmotic regulation mechanisms. Marine cryptophytes have received increasing scientific interest for their potential as sources of EPA (eicosapentaenoic acid), a valuable polyunsaturated fatty acid. Conservation status has not been assessed by the IUCN.
