Common Stinkhorn

<em>Phallus impudicus</em>, commonly known as the common stinkhorn, is a basidiomycete fungus belonging to the family Phallaceae within the order Phallales. It is widely distributed across Europe and North America, typically found in deciduous and mixed woodlands, gardens, and areas with rich organic soil. The fungus emerges from an egg-like structure partially buried in the substrate, rapidly developing a spongy, white stalk topped with a dark olive-green gleba that produces a powerful fetid odor resembling rotting flesh. This smell typically attracts flies and other insects, which disperse the spores. <em>Phallus impudicus</em> is saprotrophic, obtaining nutrients by decomposing dead organic matter, and plays an important ecological role in nutrient cycling within forest ecosystems. Biological traits such as average lifespan, precise dimensions under field conditions, and detailed dietary preferences remain poorly documented in the scientific literature. The species is currently assessed as Least Concern by the IUCN, reflecting its broad distribution and apparent population stability across its native range. It has no known significant threats at the global level.

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。
