Chyzer's Shining Claw

Chyzer's shining claw (Lamprochernes chyzeri) is a small pseudoscorpion in the family Chernetidae, found in parts of northern and central Europe including Denmark, Norway, and Sweden. Pseudoscorpions are arachnids that superficially resemble scorpions but lack a tail and stinging apparatus; instead they use venom glands in their chelicerae to subdue small invertebrate prey. Lamprochernes chyzeri inhabits decaying wood, bark crevices, leaf litter, and the nests of birds and mammals, where it preys on mites, springtails, and other small arthropods. Like many pseudoscorpions, it practices phoresy—attaching to larger insects such as beetles or flies for passive transport to new habitats. The species has a characteristic shiny or metallic appearance to its carapace, which gives the genus its name. It is classified as Least Concern, with stable populations across its Scandinavian and northern European range. The taxonomy of the genus Lamprochernes has been subject to revision, and some authors recognize closely related species as synonyms. Pseudoscorpions as a group are understudied relative to other arachnid orders, and accurate distribution data for many species, including Lamprochernes chyzeri, remain incomplete. They are generally considered beneficial in ecosystems due to their predatory role in controlling populations of soil and bark-dwelling invertebrates.

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。
