common intertidal amphipod

<em>Gammarus locusta</em>, commonly known as the common intertidal amphipod, is a crustacean in the family Gammaridae. Its conservation status has not been formally evaluated by the IUCN. The species is recorded from Denmark, Norway, Portugal, and Sweden, indicating a distribution along the northeastern Atlantic coast of Europe. It typically inhabits intertidal and shallow subtidal marine and estuarine environments, where it is found among algae, under rocks, and in sediments. Gammarus amphipods are ecologically important as detritivores and as prey for shorebirds, fish, and other invertebrates in coastal food webs. Diet information for this species is not available in current records. Biological traits of this species remain poorly documented in the scientific literature.

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.
