Common Eastern Wildrye

<em>Elymus virginicus</em>, the common eastern wildrye, is a native North American grass in the family Poaceae, currently not evaluated by the IUCN Red List. The species is documented in Denmark, Sweden, and the United States, and typically inhabits grasslands, wetlands, forests, and cultivated lands across its range in eastern and central North America. It is a cool-season, perennial bunchgrass that typically grows in moist to mesic habitats including riverbanks, floodplain woodlands, forest understories, and moist prairies. <em>Elymus virginicus</em> is recognized by its distinctive nodding seed heads with stiff, curved awns and is among the most widely distributed wild rye grasses in North America. The species provides important ecosystem services as a native ground cover, stabilizing streambanks and riparian soils against erosion, and offering habitat and food resources for grassland birds, small mammals, and invertebrates. Common eastern wildrye is also valued in ecological restoration projects for its adaptability to a range of soil conditions and its ability to establish quickly in disturbed habitats. As a forage grass, it is moderately palatable to livestock and wildlife. Biological traits of this species remain poorly documented in the scientific literature.

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.
