Studies of positional behavior, gait, and habitat use are important for understanding how animals adapt to the challenges of their environment. In turn, this information is useful for advancing research on primate morphology, life history, and ecology. Data on eco-mechanical variables can be used to develop concrete conservation and management plans for understudied and threatened primate groups. The present study explores the positional behavior, gaits, and habitat use of male and female adult golden snub-nosed monkeys (
Rhinopithecus roxellana
), an endemic, endangered, and highly dimorphic species of central China. Using focal animal sampling and opportunistic videorecording in the Guanyinshan National Nature Reserve on the southern slopes of the Qinling Mountains, it was determined that gait parameters were largely the same between sexes. By contrast, habitat use and, to a lesser extent, positional behavior varied significantly between males and females. In general, males were more terrestrial than females. When they moved arboreally, males also used a greater proportion of horizontal and large substrates compared to females. Furthermore, males used more standing postures, forelimb suspensory positional behaviors, and quadrupedal walking. These data suggest that, when faced with the mechanical challenges of large body size, primates such as
R. roxellana
are more likely to respond by altering habitat use rather than positional behaviors or intrinsic kinematics and timing.
