Coastal Mahoe

Melicytus novae-zelandiae, the coastal mahoe, is a shrub or small tree in the family Violaceae native to New Zealand, where it occurs along the coastlines of both the North and South Islands, extending to some offshore islands. The mahoes are a characteristic group of small trees and shrubs in the New Zealand flora, and M. novae-zelandiae is distinguished as the coastal ecotype of this group, tolerating salt spray, coastal winds, and the harsh conditions of maritime scrub and coastal forest margins. The species typically reaches 2–6 meters in height and produces small, yellowish-green flowers followed by fleshy purple to black fruits that are eaten by native birds including silvereyes, bellbirds, and tuis that disperse seeds through coastal scrub. Coastal mahoe provides important food and shelter resources in coastal bird habitats. Like other New Zealand violets in Melicytus, the plants are dioecious, with separate male and female individuals. The species is classified as Least Concern by the IUCN, being a naturally common component of coastal New Zealand vegetation and capable of persisting in modified coastal habitats including regenerating scrub and planted gardens. It is used in coastal revegetation and gardening for its wind and salt spray tolerance.

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。
