Feeding Postures and Substrate Use of François' Langurs () in the Limestone Forest of Southwest China.

The feeding posture of a group of François' langurs in Fusui County, Guangxi, was studied using instantaneous scan sampling from January to December 2016 to explore how the species adapts to karst limestone forests by collecting data on feeding posture, forest strata height, and substrate use. The results showed that leaves were the main food type of the François' langurs, with young leaves accounting for 64.97% ± 19.
