clubmoss leafy moss

Mnium lycopodioides is a leafy moss in the family Mniaceae, one of the larger and more conspicuous moss genera in the northern hemisphere. The name lycopodioides refers to the resemblance of the erect stems to those of clubmoss (Lycopodium) plants, with their regularly arranged, relatively large leaves. Mniaceae mosses typically have large, bordered, toothed leaves arranged in an erect to ascending posture, making them among the most easily recognizable mosses in the field. M. lycopodioides grows on moist mineral soils, rotting logs, and rock faces in boreal and temperate forests across a circumboreal distribution, occurring in northern Europe, Asia, and North America. It favors shaded, humid environments with adequate moisture year-round. Mniaceae species are important components of the boreal and temperate forest floor, contributing to moisture retention and providing microhabitats for soil invertebrates. The species is classified as Least Concern by the IUCN given its wide distribution and relatively abundant occurrence in intact boreal and montane forest habitats.

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。
