Climbing Cactus

Climbing Cactus is a common name applied to several species in the cactus family Cactaceae that have adopted a climbing or scrambling growth habit, clinging to trees, rock faces, and other supports using aerial roots or woody stems, rather than the upright or columnar forms typical of desert-dwelling cacti. Notable climbing cacti include species of Selenicereus, Hylocereus, and Epiphyllum, found in tropical and subtropical forests of Central and South America and the Caribbean. These species are often epiphytic or hemi-epiphytic, growing from forest floor to canopy by scrambling up tree trunks or clambering over rocks in humid forest environments. Many climbing cacti produce large, spectacular nocturnal flowers pollinated by bats and hawk moths, which are attracted to fragrant, white blooms opening for a single night. The dragon fruit (Hylocereus undatus) is the commercially most important climbing cactus, cultivated globally for its brightly colored, edible pitayas. Some climbing cactus species have very restricted natural ranges in tropical dry forests and coastal scrub and are threatened by habitat loss. Others have become invasive in parts of Africa, Asia, and the Pacific where they were introduced as ornamentals or for their fruit.

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.
