Chrysosphaerella annulata is a colonial freshwater chrysophyte microalga in the genus Chrysosphaerella, class Chrysophyceae. Unlike unicellular loricate chrysophytes, Chrysosphaerella species form spherical or ellipsoidal free-floating colonies in which individual cells are embedded in a common gelatinous matrix. The individual cells bear long siliceous scales with distinctive ring-like or annular structures — referenced by the species epithet annulata — projecting outward from the colony surface, giving the colony a spiny appearance under microscopy. These siliceous scales are species-specific and their morphology, as revealed through electron microscopy, is the primary character for identifying Chrysosphaerella species. C. annulata has been recorded from Norwegian and Swedish freshwater environments, consistent with the Scandinavian emphasis in chrysophyte research and the high diversity of chrysophytes in boreal freshwater systems. Chrysosphaerella colonies are planktonic, inhabiting the limnetic zone of oligotrophic to mesotrophic lakes where they may form locally conspicuous populations during favorable conditions. The species uses chlorophylls a and c with fucoxanthin for photosynthesis, contributing to primary production. Chrysosphaerella scales can accumulate in lake sediments, providing a record of past community composition and environmental conditions. C. annulata has not been assessed under IUCN criteria and is classified as Not Evaluated. Its documentation contributes to understanding the diversity of colonial chrysophyte forms in northern European freshwater ecosystems.

コンゴウインコ

南北アメリカ大陸で最も鮮やかな色彩を誇る鳥の一つであるコンゴウインコ(Ara macao)は、鮮烈な赤・黄・青の羽毛と翼開長最大1メートルの大きな翼を持ちます。メキシコからボリビアにかけての湿潤な低地森林に生息し、高い知性を持ち、最長75年の長寿で生涯を通じてつがいを形成します。種子の毒素を無害化するためにミネラル豊富な土を摂取するクレイ・リックまで長距離を移動します。軽度懸念に指定されていますが、生息地の喪失とペット取引により地域的に脅威にさらされています。
