Common Smoketree

<em>Cotinus coggygria</em>, commonly known as the Common Smoketree or Eurasian Smoketree, is a deciduous shrub or small tree in the family Anacardiaceae, order Sapindales. It has not been evaluated on the IUCN Red List, but the species is widely cultivated and naturalized across temperate regions, suggesting populations are generally stable. The common name refers to the feathery, smoke-like inflorescences that develop after flowering, produced by elongated, hairy pedicels that persist and give the plant a hazy, ethereal appearance. Native to a broad range from southern Europe through central Asia and China, <em>Cotinus coggygria</em> is typically found in rocky slopes, scrubland, dry open woodlands, and calcareous or well-drained soils in warm temperate climates. It is widely distributed across Europe, including Belgium, the Czech Republic, France, and Germany, and is also cultivated in Canada and the United States. The leaves turn striking shades of yellow, orange, and red in autumn, making this a popular ornamental plant in horticulture. As a woody plant, it obtains nutrients through soil absorption and photosynthesis. The wood and bark contain tannins and have historical uses in dyeing and traditional medicine. Specific data on lifespan and precise dimensions vary considerably with growing 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。
