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 reflexa is a species of cryptophyte alga in the family Chroomonadaceae, documented from freshwater environments in Europe. The specific epithet reflexa, meaning bent back or reflexed, likely refers to a characteristic curvature or reflex in the cell shape, flagella, or their attachment relative to the cell body. Cell shape and the arrangement of the ventral groove and flagellar insertion point are important taxonomic characters within the genus Chroomonas, and subtle morphological differences distinguish species that are otherwise similar in size and pigmentation. Chroomonas species are biflagellate, olive-green to brown or blue-green in color, and occur singly in the plankton and periphyton of freshwater systems. They are important components of microbial food webs, converting solar energy into organic biomass that is transferred to heterotrophic consumers. Cryptophytes are among the most nutritionally rich microalgae, containing elevated levels of long-chain polyunsaturated fatty acids (PUFAs) including EPA and DHA, making them highly valuable as food for zooplankton. Chroomonas reflexa has been recorded from European freshwater habitats. It has not been assessed by the IUCN.
