Canadian beaver

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.

clouded magpie

The clouded magpie (Abraxas sylvata) is a geometrid moth in the family Geometridae found across temperate Europe, extending eastward through Russia to Japan. The adult wingspan measures approximately 32–42 mm, with white wings bearing a distinctive pattern of yellow-orange and dark grey to black spots and patches arranged in rows across the forewing and hindwing, creating a striking patterned appearance resembling the magpie coloring of the related magpie moth Abraxas grossulariata, but with a more yellowish, muted tone and less black — hence 'clouded.' Adults fly in one generation from June to July, resting on leaf surfaces and attending woodland flowers for nectar. The larvae feed on wych elm (Ulmus glabra) and occasionally other Ulmus species in mature deciduous woodland and woodland edges. The clouded magpie has become less common in parts of its European range due to the widespread loss of mature elms from Dutch elm disease, which devastated European elm populations from the 1970s onward. Conservation of this species requires the protection of surviving mature elm trees and management of regrowth elms in woodland ecosystems.
