Chittick

The Chittick (Lambertia inermis) is a flowering shrub in the family Proteaceae, endemic to southwestern Western Australia — one of the world's most significant plant biodiversity hotspots. It belongs to the genus Lambertia, a small Australian endemic genus of about ten species collectively known as honeysuckles, characterised by tubular, brightly coloured flowers adapted for pollination by honeyeaters and other nectar-feeding birds. Lambertia inermis produces clusters of red or yellow tubular flowers at the branch tips, providing an important food resource for native wildlife. The species grows in the kwongan heathland and mallee scrubland vegetation communities of the Southwest Australian Floristic Region, occurring on nutrient-poor, sandy or lateritic soils. Its name inermis, meaning unarmed or spineless, distinguishes it from relatives with spiny bracts. The IUCN classifies this species as Vulnerable, reflecting the significant threats facing the Southwest Australian Floristic Region, including extensive land clearing for agriculture, altered fire regimes, disease — particularly the root rot pathogen Phytophthora cinnamomi — and increasingly severe drought driven by climate change. Conservation of kwongan heathland, through management of Phytophthora spread and sensitive fire management, is essential for the long-term survival of Chittick and hundreds of other endemic plant species sharing its habitat.

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.
