チャエリツカツクリ

<em>Talegalla jobiensis</em>, the Collared Brushturkey, is a megapode in the family Megapodiidae. This species is assessed as Least Concern on the IUCN Red List. It is native to New Guinea, occurring in lowland and hill forests where it is typically found in dense rainforest habitats. Megapodes are notable for their unique thermoregulatory breeding strategy: instead of incubating eggs with body heat, they construct large mounds of organic material in which eggs are buried and incubated by the heat generated by decomposing vegetation. <em>Talegalla jobiensis</em> belongs to a group of brushturkeys restricted to the Australasian region. Diet information typically includes invertebrates, seeds, and fallen fruit foraged from the forest floor, as is common in megapodes, though specific diet data for this species are not enumerated in available records. Biological measurements including average length, weight, and lifespan are not specified in available data. Biological traits of this species remain poorly documented in the scientific literature. Its Least Concern status reflects stable populations within its New Guinea range.

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。
