Cleft Bramble

The Cleft Bramble, Rubus laciniatus, known also as the Cutleaf or Evergreen Blackberry, is a vigorous, thorny shrub in the family Rosaceae native to central and southeastern Europe, from the Balkans through to southwestern Asia. It is widely naturalized in western North America, southern Australia, New Zealand, and other temperate regions where it was introduced as a garden plant or for erosion control. The distinctive deeply divided, laciniate leaves with finely cut leaflets distinguish it from other brambles. Like other Rubus species, it produces edible black fruits relished by birds and mammals, making it an important food plant for wildlife, but its vigorous growth and ability to root from stem tips make it an aggressive colonizer and a serious invasive species in many regions outside its native range. In the Pacific Northwest of the United States, Rubus laciniatus forms dense, impenetrable thickets that displace native vegetation and reduce biodiversity. Control is difficult given its extensive root system and the ability of fragments to regenerate. The species is listed as a noxious weed in several US states and Australian states. In its native European range, Cleft Bramble is not threatened and occurs in woodland edges, hedgerows, and scrubby habitats.

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.
