Cockroach berry

The cockroach berry (Solanum capsicoides) is a spiny, semi-woody shrub in the family Solanaceae — the nightshade family — native to eastern Brazil but now established as an invasive or naturalised weed throughout the humid tropics, including parts of Africa, Asia, Australia, and the Pacific islands. Growing to about one metre in height, it is armed with sharp, straight prickles on stems, leaves, and even the calyx, making it unpalatable to grazing animals and difficult to control mechanically. The leaves are lobed and pubescent, resembling those of other weedy solanums, and the plant produces clusters of small white flowers with yellow anthers characteristic of the genus. The globose fruits, around two to three centimetres in diameter, are initially green with white marbling and ripen to orange or red; they superficially resemble small chilli peppers or tomatoes but are toxic to humans and most livestock, containing solanine and related steroidal alkaloids. Birds are primary dispersers of the seeds, facilitating the plant's rapid spread in disturbed habitats including roadsides, forest margins, degraded pastures, and abandoned agricultural land. Solanum capsicoides is Not Evaluated on the IUCN Red List, reflecting its status as a common, widespread, and spreading species rather than one of conservation concern. In its invasive range it can form dense monospecific thickets that suppress native vegetation.

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.
