Common Lesser Toad

<em>Rhinella granulosa</em>, commonly known as the common lesser toad, is a small amphibian belonging to the family Bufonidae. This species is native to Colombia and is typically found in freshwater ecosystems, moist tropical forests, and wetland habitats. It inhabits lowland and foothill environments where moisture is consistently available throughout the year. The common lesser toad is classified as Least Concern on the IUCN Red List, indicating that its populations are currently stable and not under significant threat. Like other members of the genus Rhinella, it is typically insectivorous, feeding on small invertebrates found in its humid forest floor environment. The species plays an important ecological role as both predator of insects and prey for larger animals within its native Colombian range. Its granular skin texture, referenced in its scientific name, provides some protection from predators. Population trends remain stable, and the species benefits from the relative abundance of suitable freshwater and forest habitats across its range in Colombia.

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.
