Coast Dart

Coast dart (Euxoa cursoria) is a medium-sized moth in the family Noctuidae, native to coastal sand dunes and sandy heathland habitats of northern and western Europe, including the United Kingdom, Denmark, the Netherlands, Germany, and Scandinavia. Adults are cryptically patterned in pale buff, grey, and brown tones that match the sandy substrates of their dune habitat, flying at night from late summer into autumn. Larvae feed on the roots of coastal dune grasses and other low-growing plants, overwintering as pupae in loose sand. The genus Euxoa includes numerous 'dart' moths distributed across the northern hemisphere, many of which are habitat specialists tied to open, sandy ground. Coast dart populations have declined significantly across their European range due to the stabilisation and vegetational succession of coastal sand dunes, reduction of bare sand patches through marram grass planting, and recreational disturbance. Despite these pressures, it is assessed as Least Concern by the IUCN. In the United Kingdom, it is classified as a priority species in the Biodiversity Action Plan and is the subject of dune management programmes aimed at maintaining open sand habitat.

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.
