Choaky Berry

The Choaky Berry (Eugenia axillaris), also known as White Stopper, is a native evergreen shrub or small tree in the family Myrtaceae, occurring in coastal scrub, hammock forests, and pine rockland habitats of South Florida, the Caribbean islands, and parts of Central America. It belongs to the large genus Eugenia, which encompasses over 1,000 species of tropical and subtropical trees and shrubs — many producing edible fruits used locally as food. White Stopper typically reaches 3–10 metres in height, producing opposite, elliptic leaves with a leathery texture and small, white, four-petalled flowers with numerous stamens. The fruits are small, fleshy drupes that ripen from green through red to black-purple and are consumed by birds, which serve as the primary seed dispersers. The species is an important component of subtropical coastal and hammock ecosystems in Florida, providing food for frugivorous birds including warblers, thrushes, and vireos during migration. Its dense branching provides nesting cover for native songbirds. The IUCN classifies Eugenia axillaris as Least Concern. The name stopper traditionally refers to the genus's reported astringent properties — the juice of the fruit was used medicinally to treat diarrhoea. It is a valuable native plant for restoration and landscaping in South Florida gardens.

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.
