Ardilla Gris Oriental

동부회색다람쥐(Sciurus carolinensis)는 북아메리카 동부가 원산지이나 유럽을 비롯한 여러 지역에 성공적으로 도입된 중형 수목성 설치류로, 몸무게는 최대 600g에 달합니다. 매 가을 수천 개의 견과류와 씨앗을 땅에 묻어 저장하며, 잊어버린 저장소에서 의도치 않게 나무를 발아시키는 역할을 합니다. 영국에서는 먹이 경쟁에서 우위를 점해 토착종인 붉은다람쥐를 대부분 대체했습니다.

Common Pipistrelle

<em>Pipistrellus pipistrellus</em>, the common pipistrelle, is a small bat in the family Vespertilionidae and one of the most abundant and widespread bat species in Europe. It is typically one of the first bats to emerge at dusk, flying with rapid, jerky wingbeats as it pursues small flying insects over gardens, woodland edges, water bodies, and urban areas. The species roosts in crevices in buildings, bat boxes, and tree holes, often forming large maternity colonies in summer. <em>Pipistrellus pipistrellus</em> echolocates at a characteristic frequency of around 45 kHz, which allows it to be identified using bat detectors. It is distributed across Europe, with confirmed records from Belgium, Denmark, Luxembourg, Norway, and Portugal, among many other countries. The species is assessed as Vulnerable on the IUCN Red List, reflecting population declines driven by loss of foraging habitat, reduction in insect prey biomass, disturbance of roost sites, and pesticide use. Biological traits such as average lifespan, body size, weight, and detailed dietary composition across its range remain poorly documented in the scientific literature, though the species is known to consume large numbers of small moths, midges, and other aerial insects each night.
