Comb windmill grass

<em>Chloris pectinata</em>, the comb windmill grass, is a grass in the family Poaceae with a distribution across Asia, Europe, and North America. It grows in disturbed and open habitats including roadsides, waste ground, dry grasslands, and agricultural margins, reflecting adaptability to degraded and human-modified environments. The genus <em>Chloris</em> is recognized by its distinctive windmill-like arrangement of spreading finger-like branches bearing one-sided rows of spikelets, which give the species an ornamental quality. The species epithet pectinata refers to the comb-like appearance of the inflorescence. <em>C. pectinata</em> is an annual or short-lived perennial grass that reproduces primarily by seed. It is adapted to dry, warm climates and tolerates poor soils. In some regions, it is considered a ruderal weed, while in others it may serve as a minor forage grass. Specific biological metric data are not available in the current record.

Polar bear

지구상에서 가장 큰 육상 육식동물인 북극곰은 700kg을 넘을 수 있으며 캐나다에서 러시아까지 북극 해빙 전역에 분포한다. 고리 물범과 수염 물범을 사냥하기 위해 해빙에 의존하는 고도로 특수화된 해양 포유류이다. 광활한 거리를 헤엄쳐 다닐 수 있는 뛰어난 수영 실력을 가지고 있다. 취약종으로 등재되어 있으며, 기후 변화로 인한 급격한 북극 해빙 감소로 심각한 압력을 받고 있다.
