アリサンヒタキ

<em>Tarsiger johnstoniae</em>, the Collared Bush Robin, is a small passerine bird in the family Muscicapidae. This species is assessed as Least Concern on the IUCN Red List. It is documented in Taiwan, where it is endemic and inhabits montane forests, particularly in dense undergrowth at higher elevations. Members of the genus <em>Tarsiger</em> are typically shy, ground-foraging birds that feed on insects and other small invertebrates. The Collared Bush Robin is named for the distinctive collar pattern in the male's plumage, which contrasts with the brownish coloration of the female. Diet, population estimates, population trend, and biological measurements such as average length, weight, and lifespan are not specified in the available records. Biological traits of this species remain poorly documented in the scientific literature. Its Least Concern designation indicates that the population is not currently at elevated extinction risk, though as a Taiwanese endemic restricted to montane forest, it may be sensitive to climate-induced shifts in its habitat.

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。
