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.

Polar bear

地球上で最大の陸上肉食動物であるホッキョクグマは700kgを超えることがあり、カナダからロシアまでの北極海氷域全体に分布する。ワモンアザラシとヒゲアザラシを狩るために海氷に依存する高度に特化した海洋哺乳類である。広大な距離を泳ぐことができる優れた泳者でもある。脆弱種に指定されており、気候変動による急激な北極海氷の消失で個体群が深刻な圧力を受けている。
