“…Knowledge on the home range size of a species or population is of great importance for understanding its behavioral and social ecology (Isbell, 1991; Snaith & Chapman, 2007; Zhou et al, 2007) and for improving the effectiveness of conservation strategies (Bryant et al, 2017; Huang et al, 2017). The home range size of non-human primates (hereafter, primates) is influenced by a range of ecological and behavioral factors, including food availability and distribution (Curtis & Zaramody, 1998; Zhang et al, 2014; Zhou et al, 2007), group size (Dias & Strier, 2003; Gillespie & Chapman, 2001; Li et al, 2010), sleeping site location (Zhou et al, 2011), water availability (Scholz & Kappeler, 2004), parasite avoidance (Freeland, 1980), topography (Fan & Jiang, 2008), and intergroup relationships (Benadi et al, 2008).…”
