Common Chinese Treefrog

<em>Hyla chinensis</em>, commonly known as the common Chinese treefrog, is an amphibian species found in Taiwan. It typically inhabits freshwater environments, moist forests, and wetlands, often occurring near ponds, streams, rice paddies, and other water bodies where it breeds during the warm season. The species is classified as Least Concern on the IUCN Red List, reflecting a currently stable population within its limited geographic range. Common Chinese treefrog belongs to the genus <em>Hyla</em> within the family Hylidae. It is a small, arboreal frog that typically spends much of its life in vegetation above ground, descending to water primarily to breed. Like other tree frogs, it possesses adhesive toe pads that facilitate climbing on smooth surfaces such as leaves and stems. Biological traits such as average lifespan, body length, and mass of this species remain poorly documented in the scientific literature. As an amphibian species, it is potentially sensitive to habitat loss, water pollution, and climate-related changes affecting its freshwater breeding habitats in Taiwan.

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.
