Club-Spur Orchid

Platanthera clavellata, the small green wood orchid or club-spur orchid, is a terrestrial orchid in the family Orchidaceae native to eastern North America, from Newfoundland and Manitoba south to Florida and Texas. The species grows in a variety of moist to wet habitats including bogs, fens, wet meadows, seeps, swamps, and moist deciduous or coniferous forests. It typically produces a single large basal leaf and a slender flowering stem bearing small, greenish-white or pale yellow flowers arranged in a loose spike. Like other Platanthera orchids, it is pollinated by night-flying moths attracted to its faint fragrance. The club-shaped spur of the flower, which contains nectar, gives the species its common name. P. clavellata is not currently assessed by the IUCN (Not Evaluated), but is considered secure across much of its range in Canada and the eastern United States, though local populations may be threatened by wetland drainage, habitat conversion, and browsing by deer. The species depends on symbiotic mycorrhizal fungi in the soil for germination and early growth, as is typical for terrestrial orchids.

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。
