Common Star-apple

<em>Diospyros dichrophylla</em>, commonly known as the common star apple or bladder nut, is a small deciduous tree or shrub in the family Ebenaceae, native to southeastern Africa. This species typically inhabits riverine forests, bushveld margins, rocky hillsides, and scrubby thickets in subtropical and tropical woodland regions. It is distributed across southern and eastern Africa, with populations recorded in South Africa (particularly KwaZulu-Natal and Limpopo), Eswatini, Mozambique, and Zimbabwe. Classified as Least Concern on the IUCN Red List, <em>Diospyros dichrophylla</em> remains relatively widespread within suitable habitats across its range. The species produces small edible fruits that ripen to yellow or orange and are eaten by wildlife including birds and small mammals. The flowers are white and fragrant, and the plant is sometimes cultivated as an ornamental or for its edible fruit. Biological traits such as average lifespan, body dimensions, and dietary specifics remain poorly documented in the scientific literature for this plant species. The common name "star apple" in this context refers to the star-like pattern visible when the fruit is cut in cross-section. The species is ecologically important as a food and shelter resource for local fauna in its southeastern 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。
