Habitat & Geographic Range
Common Plain Neb
Typically found in virtually all terrestrial and freshwater habitats.
Distributed across Belgium, Denmark, Norway, and Sweden.
Polar bear
Found across multiple habitat types including temperate broadleaf and mixed forests, temperate coniferous forests, and boreal forests and taiga, among 4 distinct biome types within the Palearctic biogeographic realm. Populations are also found in montane and highland environments at higher elevations.
Found in Norway. Currently classified as Vulnerable on the IUCN Red List, this species faces significant conservation challenges across its range.
Common Plain Neb
<em>Monochroa tenebrella</em>, the common plain neb, is a small moth in the family Gelechiidae, a large and taxonomically complex family of micromoths. It is a nondescript, grey-brown species with narrow forewings typical of the gelechiid body plan, making field identification challenging without close examination. The species is typically associated with wetland and riparian habitats, where its larval host plants are found, and adults are usually encountered in late spring and early summer. <em>Monochroa tenebrella</em> is distributed across northern Europe, with confirmed records from Belgium, Denmark, Norway, and Sweden, suggesting a preference for temperate Atlantic and continental European climates. It is assessed as Least Concern on the IUCN Red List, reflecting an absence of major known threats at the population level. Biological traits such as average adult lifespan, wingspan measurements beyond general range estimates, larval host plant associations, and detailed dietary data remain poorly documented in the scientific literature. Like many micromoths, the species is understudied relative to larger Lepidoptera, and its ecology, population dynamics, and responses to habitat change are not well characterised. Continued recording by amateur lepidopterists is important for monitoring its distribution and 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.
