Abstract:A group of François' langur (Trachypithecus francoisi) in the Nonggang Nature Reserve, Guangxi, China was observed from December 2005 to February 2006. Data on habitat selection of the study group was collected by instantaneous scan sampling method to explore the strategy of adaption to karst limestone hills during dry season. The results indicated that the east orientation constituted 64.95% of the hill parts used by the langurs, followed by north 20.22%, south 9.08% and west 5.74%, respectively. It could be regarded as the result of the langurs’ thermoregulation. According to the total hill parts habitat records, the cliff was preferred, with a higher percentage (40.27%) both than bottom (29.52%), slope (22.18%), and the top (8.04%). The use of vertical space showed significant variations with activities. Cliff was mainly selected for resting area, which contributed 55.92% to the total records, while the bottom was used for feeding sites with a 59.71% proportion in the records. Trees used as preferred microhabitat accounted for 68.04% of the total records. Bare rock and bush constituted 22.27% and 4.69%, respectively. The preference of the different hill parts could be resulted from the langurs’ balance of the feeding benefit and prey risk. Our results provide data to comprehend the adaption strategy of langurs, and provide the foundation to habitat conservation.
