Common Lime

<em>Tilia europaea</em>, the common lime or European linden, is a large deciduous tree in the family Malvaceae, occurring naturally as a hybrid between <em>Tilia cordata</em> and <em>Tilia platyphyllos</em>. It is widely distributed across Europe and has been introduced to North America, where it is commonly planted as a street and park tree. The common lime typically grows in temperate broadleaf forests and urban environments, reaching considerable heights and living for several centuries. It produces fragrant, pale yellow flowers in summer that are highly attractive to bees and other pollinators, earning it a prominent role in honey production. The species has not been assessed for the IUCN Red List. Its wood is valued for carving and musical instrument manufacture, while its flowers and leaves have traditional uses in herbal medicine. Common lime is particularly notable for producing abundant basal sprouts and epicormic shoots, a characteristic that makes it useful for coppicing and pollarding in traditional land management practices across Europe and North America.

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.
