Application of a combined model simulation to determine ecological corridors for western black-crested gibbons in the Hengduan Mountains, China

Habitat fragmentation is a critical contributor to biodiversity degradation and species extinction, as illustrated by the severely fragmented habitat of the western black-crested gibbon (Nomascus concolor), a critically endangered species in the Hengduan Mountains, China. An integrated simulation mo...

The planned corridor is an optimized route for western black-crested gibbons in the Hengduan Mountains, and provides the best opportunities for security, food, and survival.
