Climbing Bindweed

Climbing Bindweed, Calystegia sepium or related Convolvulus species in the family Convolvulaceae, is a vigorous twining perennial vine native to temperate regions of Europe, Asia, and North America, widely naturalized in disturbed habitats worldwide. The species climbs over hedgerows, fences, tall herbs, and shrubs by twining its flexible stems counterclockwise around supporting structures, sometimes smothering vegetation under dense leafy growth. The leaves are broadly arrow-shaped or hastate, and the funnel-shaped flowers are large, white to pale pink, and open during daylight hours. Like its relatives, Climbing Bindweed has deeply buried, extensively spreading rhizomes that are extremely difficult to eradicate once established. The extensive root system enables survival of herbicide treatments and mechanical disturbance, making the species a persistent weed in gardens, agricultural land, and riparian habitats. Despite its weedy character, the flowers provide nectar for bumblebees and are visited by hawk moths at dusk. The species is not threatened globally; it is considered common and often invasive across temperate regions. It has considerable cultural significance, appearing frequently in art and folklore as a symbol of persistence and entanglement.

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.
