Chrysosphaerella triangulata is a colonial freshwater chrysophyte microalga in the genus Chrysosphaerella, class Chrysophyceae, order Chromulinales. Chrysosphaerella species form spherical free-floating colonies of golden-brown cells embedded in a gelatinous matrix, with individual cells bearing elongated siliceous scales that project outward from the colony surface. The species epithet triangulata — triangular — refers to the triangular cross-section or profile of the siliceous scales on the cell surface, which distinguishes this species from C. annulata, which has annular ring structures on its scales, and from other congeners with different scale geometries. Siliceous scale morphology examined under scanning electron microscopy is the primary diagnostic character for Chrysosphaerella species identification. C. triangulata has been recorded from Norwegian and Swedish freshwater habitats, part of the documented chrysophyte flora of boreal and subarctic Scandinavian lakes. These environments are characterized by cold, clear, nutrient-poor water and seasonal ice cover, creating conditions favorable for chrysophyte diversity including colonial forms like Chrysosphaerella. The colonies inhabit the photic zone of the water column, photosynthesizing with chlorophylls a and c and carotenoid accessory pigments. Chrysosphaerella scales deposited in lake sediments serve as paleolimnological indicators. C. triangulata has not been formally evaluated under IUCN criteria and is listed as Not Evaluated. It contributes to documentation of the rich chrysophyte diversity in Scandinavian freshwater systems.

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。
