Chroococcus prescottii is a species of cyanobacteria in the family Chroococcaceae, named in honor of the American phycologist Gerald Weber Prescott, who made major contributions to the study of freshwater algae in North America during the twentieth century. Like other Chroococcus species, it consists of spherical cells arranged in pairs or small groups within a gelatinous sheath matrix. Cyanobacteria of this genus are common inhabitants of freshwater lakes, bogs, and other aquatic environments across temperate and boreal regions. Chroococcus prescottii has been documented from North American and European freshwater localities. The species occupies the plankton or periphyton of its host water bodies, contributing to primary production through photosynthesis. In aquatic food webs, small cyanobacteria serve as food for herbivorous zooplankton such as cladocerans and copepods, linking primary production to higher trophic levels. The taxonomy of Chroococcus has been complicated by the variable expression of morphological characters under differing environmental conditions and by the recognition through molecular analysis that the genus as traditionally defined is polyphyletic. Chroococcus prescottii has not been assessed by the IUCN.

koala

オーストラリア東部・南東部を代表する有袋類で、体重は最大15kgに達し、低カロリーのユーカリの葉食から得るエネルギーを節約するために1日最大22時間を睡眠に費やす。他の哺乳類の多くを死に至らしめる有毒なユーカリ成分を処理するために高度に特化しており、解毒に特別に適応した腸内微生物叢を持つ。クラミジア感染症、生息地の伐採、気候変動により個体数が激減し、2022年に絶滅危惧種に指定された。
