Cliff Net-bush

Cliff Net-bush, Calothamnus rupestris, is a small shrub in the family Myrtaceae endemic to southwestern Western Australia, one of the world's recognized biodiversity hotspots. Calothamnus species, known as net-bushes or one-sided bottlebrushes, are characterized by their distinctive flower clusters arranged in a one-sided bottlebrush pattern along woody stems, with brush-like red staminal bundles typical of the genus. Cliff Net-bush grows on cliff faces, rocky slopes, and granite outcrops in the kwongan heathland of the Southwest Australian Floristic Region, tolerating the thin, nutrient-poor soils and periodic drought characteristic of these rocky substrates. The flowers provide nectar for native honeyeaters and insects. Like the majority of southwest Australian endemic plants, Cliff Net-bush is adapted to the ancient, nutrient-impoverished soils of the Gondwanan continent and the Mediterranean-type climate with hot, dry summers and mild, wet winters. Threats facing southwest Australian heathland endemics include habitat clearing for agriculture, dieback disease caused by the introduced pathogen Phytophthora cinnamomi, altered fire regimes, and climate change. The conservation status of Calothamnus rupestris requires monitoring given the overall pressure on southwest Australian flora.

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。
