Click beetle

Click Beetle 2 represents another species among the over 10,000 members of the family Elateridae, sharing the family's characteristic body plan and the distinctive clicking mechanism used for self-righting. Elaterid beetles occupy a wide range of ecological niches from soil-dwelling larvae that consume roots and decaying wood to adults that visit flowers or feed on fungal tissue. The specific species referred to by this entry may belong to any of numerous genera within the family, each adapted to particular habitats and host resources. In tropical regions, click beetles include brightly luminescent species in the genera Pyrophorus and Ignelater, which produce bioluminescent light from paired spots on the thorax to attract mates. In temperate regions, economically important wireworm species of genera Agriotes and Melanotus are significant pests of agricultural crops. Some click beetle larvae are predatory, feeding on wood-boring beetle larvae and other soil invertebrates. The diversity of ecological strategies within Elateridae makes them important components of both forest and agricultural ecosystems. Conservation status depends entirely on the specific taxon in question; the majority of click beetle species have not been formally assessed.

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。
