ウロコヤマミツスイ

The cinnamon-browed melidectes (Melidectes ochromelas) is a medium-sized honeyeater in the family Meliphagidae, endemic to the highlands of New Guinea, including both the Indonesian provinces of Papua and West Papua and Papua New Guinea. It inhabits montane and subalpine forest, moss forest, and forest edge at elevations typically between 2,000 and 3,500 meters. The species is characterized by a cinnamon-rufous supercilium (eyebrow) stripe that contrasts with its otherwise brown and streaked plumage. Melidectes honeyeaters are large, robust birds that forage for nectar, fruit, and invertebrates in the forest canopy and subcanopy. The cinnamon-browed melidectes is classified as Least Concern by the IUCN, with stable populations across a wide elevational and geographic range in New Guinea's mountains. New Guinea is one of the world's greatest centers of bird diversity and endemism, particularly in highland habitats. The species is absent from Europe entirely; Norwegian database records are data entry artifacts. Montane forest in New Guinea remains relatively well intact compared to lowland forest, reducing immediate habitat loss pressures. Mining, road-building, and agricultural expansion at higher elevations are increasing threats. Honeyeaters play important roles as pollinators in New Guinea's montane plant communities.

Polar bear

地球上で最大の陸上肉食動物であるホッキョクグマは700kgを超えることがあり、カナダからロシアまでの北極海氷域全体に分布する。ワモンアザラシとヒゲアザラシを狩るために海氷に依存する高度に特化した海洋哺乳類である。広大な距離を泳ぐことができる優れた泳者でもある。脆弱種に指定されており、気候変動による急激な北極海氷の消失で個体群が深刻な圧力を受けている。
