Christmasberry

Christmasberry (Heteromeles arbutifolia) is an evergreen shrub or small tree in the family Rosaceae, native to coastal and inland California and Baja California, Mexico. It is the sole species in the genus Heteromeles and is one of the most characteristic and ecologically important plants of California chaparral and coastal sage scrub communities. The plant produces large, flat-topped clusters of small white flowers in summer, followed by bright red berries that ripen in autumn and persist into winter, providing critical food resources for birds and other wildlife during a season of relative scarcity. The berries were an important food source for many California Indigenous peoples, who consumed them after leaching and cooking to reduce cyanogenic compounds naturally present in the raw fruit. Christmasberry is highly drought-tolerant and fire-adapted, capable of resprouting vigorously from a lignotuber following wildfire. Its dense, stiff branches with serrated, holly-like leaves provide cover and nesting habitat for birds. The species is widely used in native plant landscaping and restoration in California due to its attractiveness to wildlife and adaptability to dry conditions. Christmasberry has no significant conservation concerns and is considered common throughout its 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。
