coast banksia

Coast banksia (Banksia attenuata) is an erect shrub or small tree in the family Proteaceae, endemic to the southwestern coastal region of Western Australia. It is one of the most abundant banksias in the northern sandplains and coastal heathland of the Southwest Australian Floristic Region, growing on deep, nutrient-poor white or yellow sands in kwongan heathland and woodland. It produces tall yellow cylindrical flower spikes that are an important nectar resource for honeyeaters, nectarivorous mammals, and invertebrates. The distinctive long, narrow, serrated leaves and persistent old follicles on flowering spikes are identifying characteristics. Banksia attenuata is assessed as Vulnerable by the IUCN, primarily due to the devastating impact of Phytophthora cinnamomi, a water mould causing dieback that has killed extensive areas of kwongan heathland in southwestern Australia. Additional threats include inappropriate fire regimes, habitat clearing, and the effects of reduced rainfall associated with climate change in the southwest. It is among the most studied banksias in relation to plant pathogen impacts and serves as a model organism in research on conservation responses to Phytophthora.

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。
