Common Pipsissewa

<em>Chimaphila umbellata</em>, the common pipsissewa or prince's pine, is an evergreen subshrub in the family Ericaceae, characterised by whorled, toothed, leathery leaves and nodding, waxy pink to white flowers borne in small clusters on slender stems. It typically grows in dry to moist coniferous and mixed forests, often in humus-rich soils with a dense duff layer, where it depends on mycorrhizal associations for nutrient uptake. The species is distributed across Europe, including Belgium, Denmark, Finland, France, and the Netherlands, and in North America including the United States, reflecting a circumboreal distribution pattern. <em>Chimaphila umbellata</em> is assessed as Endangered on the IUCN Red List, indicating significant population declines attributed to habitat loss through forest conversion, fire suppression altering forest structure, and disruption of fungal symbiont communities. It is a slow-growing, long-lived plant with limited capacity for rapid recovery following disturbance. Biological traits such as precise average lifespan, plant dimensions, and detailed dietary and physiological parameters remain poorly documented in the scientific literature. The plant has a history of use in traditional herbal medicine among Indigenous North American peoples, who used it to treat kidney and urinary conditions.

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。
