북아메리카에서 가장 큰 설치류인 캐나다비버는 체중이 최대 32kg에 달하며 캐나다 및 미국 북부의 강, 호수, 습지에 서식하는 생태계 공학자의 대가입니다. 나무를 베고 수백 미터에 달하는 댐을 건설하여 수백 종에게 서식지를 제공하는 연못을 만들어냅니다. 이들의 보금자리와 수로는 유역 전체를 변화시킵니다. 한때 모피를 위한 남획으로 거의 멸종 위기에 처했으나, 비버 개체군은 강하게 회복되었습니다.

Collared Lark

The Collared Lark, known scientifically as <em>Mirafra collaris</em>, is a small passerine bird belonging to the family Alaudidae. As a member of the diverse lark genus Mirafra, <em>Mirafra collaris</em> is characterised by its cryptic, streaked brown plumage that provides effective camouflage in its preferred open habitats. The species typically inhabits open grasslands, savannas, and scrubby areas, where it forages on the ground for seeds and insects. It is reported to occur in Norway according to available range data. Larks of this group are generally ground-nesters, constructing their nests in shallow depressions among vegetation. Detailed biological traits including typical lifespan, body length, and weight are poorly documented for this species in available literature. The Collared Lark is currently assessed as Least Concern on the IUCN Red List, suggesting that the population is stable and not subject to significant conservation pressure at a global level.
