|Abstract:||© 2015 Wiley Periodicals, Inc. Space-use patterns are crucial to understanding the ecology, evolution, and conservation of primates, but detailed ranging data are scarce for many species, especially those in Southeast Asia. Researchers studying site fidelity to either home ranges or core areas have focused mainly on territorial species, whereas less information is available for non-territorial species. We analyzed the ranging patterns and site fidelity of one wild troop of northern pigtailed macaques over 16 months at different temporal scales. We used characteristic hull polygons in combination with spatial statistics to estimate home ranges and core areas. The total home range and core areas were 449ha and 190ha, respectively. Average daily path length was 2,246m. The macaques showed a high defendabili--ty index according to the expected ranging of a non-territorial species in which movement does not theoretically permit the defense of a large territory. Overall, the study troop ranged more extensively than conspecific groups and closely related species studied elsewhere. These differences may reflect variable troop size, degree of terrestriality and habitat characteristics, but could also reflect methodological differences. The location, size and shape of home ranges and core areas, and extent of daily path lengths changed on a monthly basis resulting in low site fidelity between months. The macaques also showed clear shifts in the location of daily home ranges with low site fidelity scores between consecutive days. Daily home range and daily path length were related to seasonality, with greater values during the fruit-abundant period. Low site fidelity associated with lack of territoriality is consistent with macaques structuring their movement based on available food sources. However, ranging patterns and site fidelity can also be explained by macaques feeding on the move, a foraging strategy that hinders frequent and long visits to the same location.|
