title: The seasonal daily travel in a group of Sichuan snub-nosed monkey (Pygathrix roxellana) in Shennongjia Nature Reserve, China.
abstract: The seasonal daily travel of a group of snub-nosed monkey (Pygathrix roxellana) was investigated using the group's straight-line distance method. The group was followed from dawn to dusk for 30 consecutive days during each season to encompass all aspects of daily travel patterns. The results showed that in Summer and Autumn, the mean daily travel distance (m) was significantly longer than in Winter and Spring. There was no significant difference in the mean daily travel distance between Summer and Autumn or between Winter and Autumn. The mean travel distance (m/hr) during daytime was significantly higher in Summer and Autumn than in Spring, and in Autumn than in Winter. The travel of the group in all seasons had similar patterns. Traveling showed morning and afternoon peaks, with a rest period at the noon in a day. Seasonal food availability, length of daytime, and mean travel distance (m/hr) during daytime might have contributed to the different daily travel distances in different seasons.
