Seasonal home range changes of the Sichuan snub-nosed monkey (Rhinopithecus roxellana) in the Qinling mountains of China

The seasonal changes in home range and habitat use of the Sichuan snub-nose d monkey, Rhinopithecus roxellana, have been studied by radio tracking and direct observation in the Qinling Mountains of China. The home range size w as 14.1 km(2) in spring, 9.5 km(2) in summer, 12.1 km(2) in autumn and 12.3 km(2) in winter; the total area used was 22.5 km(2). The area of the home range is closely correlated with the distribution and abundance of food res ources. Seasonal change in the home range area is correlated with the pheno logy of the vegetation. An unusually large home range is a unique character istic of this monkey. Copyright (C) 2001 S. Karger AG, Basel.
