The prominent ones are the Owston's Civet Hemigalus owstoni (globally vulnerable), Francois's Leaf Monkey Trachypithecus francoisi and Tonkin Snub-nosed Monkey Rhinopithecus avunculus (the globally critically endangered).

However, in a detailed observation of the free-ranging band in the Qinling Mountains in central China, results have suggested that winter night activity of Rhinopithecus Roxellana is a compromise between antipredator and thermoregulatory strategies and an adaptation to ecological conditions of their temperate habitat.
