clusterleaf

Terminalia sericea, known as clusterleaf or silver terminalia, is a medium-sized deciduous tree in the family Combretaceae native to the savanna woodlands and bushveld of southern Africa, ranging from South Africa through Zimbabwe, Botswana, Namibia, and into Zambia and Mozambique. The species is a characteristic and abundant component of the broad-leaved miombo and mopane woodland systems of the region. Trees typically reach 6–12 meters in height, distinguished by their distinctive silvery-grey leaves clustered at branch tips, which account for the common name clusterleaf. The leaf undersides are covered with fine silky hairs giving a silver sheen that is particularly visible in sunlight and dry season conditions. Terminalia sericea is prized for its dense, durable hardwood, and extracts from the roots, bark, and leaves have extensive applications in traditional African medicine, being used to treat infections, stomach complaints, and malaria symptoms. Pharmacological research has confirmed antimicrobial and anti-inflammatory properties in the species. It produces small, winged fruits that are wind-dispersed across the savanna landscape. The species is assessed as Least Concern by the IUCN and remains common and widespread across its southern African range.

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。
