Clustered Feather-moss

Rhynchostegium confertum, the clustered feather moss, is a pleurocarpous moss in the family Brachytheciaceae distributed across Europe, where it grows on rocks, walls, tree bases, and compacted soil in a variety of habitats including woodland, gardens, churchyards, and urban environments. The plants form dense, bright green to yellowish-green mats with pinnately branched stems bearing small, ovate-lanceolate leaves. This species is listed as Near Threatened by the IUCN, reflecting concerns about population declines in parts of its European range, possibly related to air quality changes, habitat alteration, and drought. Brachytheciaceae mosses are common components of temperate and boreal flora, and R. confertum is one of the more urban-tolerant members of the family, occurring even in heavily built environments. Like all pleurocarpous mosses, R. confertum spreads vegetatively through fragmentation and produces spores from upright, slender sporophytes during the reproductive season. It contributes to moisture retention on substrates and provides microhabitats for invertebrates in urban and semi-natural environments.

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。
