Common Oak

유럽에서 가장 중요하고 널리 분포하는 낙엽수 중 하나인 영국참나무(Quercus robur)는 1,000년 이상 살 수 있으며 높이 40m에 달하고, 어떤 유럽 수종보다 다양한 생물다양성을 지원한다. 2,300종 이상의 곤충·균류·지의류·이끼·조류가 노령 참나무에 직접 의존한다. 유럽 전역에서 서아시아에 이르는 온대림에 분포하며, 단단하고 내구성 있는 목재는 역사적으로 조선, 건축, 통 제조에 필수적이었다.

Complex-toothed Flying Squirrel

<em>Trogopterus xanthipes</em>, the complex-toothed flying squirrel, is a medium-sized gliding rodent in the family Pteromyidae endemic to China, where it inhabits montane broadleaf and mixed forests at elevations typically between 1,000 and 2,700 metres in provinces including Sichuan, Yunnan, Guizhou, Hubei, and neighbouring regions. This species is the sole member of the genus Trogopterus and is distinguished by complex tooth morphology compared to other flying squirrels. Like all flying squirrels, it possesses a patagium — a gliding membrane stretching between fore and hind limbs — that enables it to glide between trees rather than undertake powered flight. The complex-toothed flying squirrel is nocturnal and arboreal, spending its days sheltering in tree hollows and foraging at night for leaves, bark, seeds, and fungi. Its faeces, known as Wuflingzhi, have been used in traditional Chinese medicine for centuries, leading to trapping pressure in parts of its range. The IUCN classifies this species as Near Threatened, reflecting population decline driven by overhunting for medicinal use and ongoing habitat loss from logging and agricultural encroachment in montane forests. Biological traits including average body mass, lifespan, litter size, and home range are partially documented but detailed population estimates are limited. Conservation measures include legal protections under Chinese wildlife law.
