Collie Jacksonia

<em>Jacksonia velveta</em>, commonly known as Collie Jacksonia, is a plant species belonging to the genus <em>Jacksonia</em> within the family Fabaceae. This species is classified as Endangered, reflecting significant concern over its population status and the ongoing threats it faces within its native range. It has been documented in terrestrial and freshwater-associated habitat types, suggesting association with diverse environmental conditions typical of its region. <em>Jacksonia</em> species are generally shrubs or small trees native to Australia, and members of this genus are frequently found in heathland and woodland communities where they contribute to ground-cover vegetation. Specific country-level records are not detailed in current documentation for this species. Dietary behavior is not applicable to plant organisms; however, like other legumes, <em>Jacksonia velveta</em> may engage in nitrogen fixation through root-associated symbioses. Biological traits of this species remain poorly documented in the scientific literature. Conservation efforts for Endangered plant species such as <em>Jacksonia velveta</em> typically focus on habitat protection and restoration.

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.
