club pincushion moss

Ulota coarctata, the club pincushion moss, is an epiphytic moss in the family Orthotrichaceae, growing on the bark of deciduous and occasionally coniferous trees in Europe and North America. The genus Ulota is characterized by strongly crisped and contorted leaves when dry that straighten upon wetting, a hygroscopic response that aids in identifying these mosses in the field. U. coarctata forms small, compact, cushion-like tufts on branches and trunk surfaces, typically on trees with nutrient-rich, rough-barked species such as elder, hazel, and ash. It is listed as Vulnerable by the IUCN, reflecting declines associated with atmospheric pollution, particularly sulfur dioxide emissions that historically acidified bark surfaces and eliminated sensitive epiphytic bryophyte and lichen communities across much of western Europe. Since reductions in air pollution since the 1970s, some orthotrichaceous mosses have begun recovering in previously polluted regions. U. coarctata requires relatively clean air conditions and adequate atmospheric moisture, making it a useful bioindicator of air quality. Conservation depends on continued air quality improvement and retention of mature deciduous trees.

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。
