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.

Comoro Rousette

<em>Rousettus obliviosus</em>, the Comoro rousette, is a fruit bat in the family Pteropodidae endemic to the Comoros archipelago in the Indian Ocean, primarily recorded from Anjouan and Mohéli islands. As an Old World fruit bat, it plays an important ecological role in pollination and seed dispersal across the island's native forests. The species inhabits tropical moist lowland and montane forests, roosting in caves and dense vegetation. Its range is severely restricted by the small land area of the Comoros, making it inherently vulnerable to habitat loss. Deforestation driven by agricultural expansion and charcoal production has significantly reduced available forest cover on the islands. The IUCN classifies the Comoro rousette as Vulnerable, reflecting ongoing population pressures and limited geographic distribution. It is presumed to feed on fruits, nectar, and pollen typical of Old World fruit bats, though detailed dietary studies are limited. Biological traits including precise body measurements and lifespan data remain poorly documented in the scientific literature. Conservation efforts on the Comoros islands face challenges due to limited resources, though the species benefits from some protection within national parks and forest reserves. Its survival depends on the preservation of intact native forest habitat across the archipelago.
