Common Sun Beetle

<em>Amara aenea</em>, the common sun beetle, is a carabid ground beetle in the family Carabidae, order Coleoptera. It is broadly distributed across Europe and has been introduced to North America, typically inhabiting open, sunny habitats such as arable fields, grasslands, sandy heathlands, and disturbed ground with sparse vegetation. Adults are omnivorous, feeding on seeds, small invertebrates, and plant material, and are considered important predators of weed seeds in agricultural systems. <em>Amara aenea</em> is surface-active during warm, dry conditions, typically exhibiting peak activity in late spring and summer. Like many carabid beetles, it is nocturnal and shelters under stones and debris during the day. Larvae develop in the soil, where they also feed on organic matter and small invertebrates. Biological traits including precise adult lifespan, body length measurements, and detailed prey preferences remain poorly documented at the species level. The species is assessed as Least Concern by the IUCN, reflecting its wide distribution, high adaptability to disturbed environments, and no significant known threats to global population status.

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.
