carvalheiro

Uno de los árboles caducifolios más importantes y extendidos de Europa, el roble pedunculado (Quercus robur) puede vivir más de 1.000 años, alcanzar 40 metros de altura y albergar la mayor biodiversidad de cualquier especie arbórea europea: más de 2.300 especies de insectos, hongos, líquenes, musgos y aves dependen directamente de los robles maduros. Distribuido por Europa hasta Asia occidental en bosques templados, su madera dura y duradera ha sido fundamental en la construcción naval, la arquitectura y la fabricación de barriles a lo largo de la historia.

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.
