Canadian beaver

北米最大の齧歯類であるカナダビーバーは体重32kgにも達し、カナダ・米国北部の河川、湖沼、湿地に生息する優れた生態系エンジニアです。木を倒して数百メートルに及ぶダムを造ることで池を形成し、数百種の生息環境を提供します。その巣穴や運河は流域全体を変化させます。かつては毛皮のために絶滅寸前まで狩られましたが、個体数は大きく回復しています。

common wave

<em>Cabera exanthemata</em>, commonly known as the common wave, is a moth in the family Geometridae, distributed across much of Europe, with confirmed records from Belgium, Canada, Denmark, Norway, and Sweden. It is classified as Least Concern by the IUCN, indicating a stable population with no major threats currently identified. The species is associated with deciduous woodland habitats, particularly areas with abundant birch, alder, and willow trees, which serve as larval host plants. Adults are pale whitish-gray with a series of fine, wavy darker cross-lines on the wings — a pattern typical of many geometrid moths that provides camouflage against lichen-covered tree bark. <em>Cabera exanthemata</em> typically produces two or three generations per year depending on latitude, with adults typically on the wing from May through August. Larvae feed on the foliage of various deciduous trees and overwinter as pupae in the soil or leaf litter. The species is primarily nocturnal as an adult, attracted to light sources during flight periods. Biological traits including average lifespan, wingspan dimensions, and mass remain poorly documented in standardized databases. Ecologically, the common wave contributes to forest food webs as both a herbivore during its larval stage and as a food resource for insectivorous birds and bats during its adult flight period throughout its temperate European and North American range.
