Abstract
The activity patterns of Dasyprocta mexicana were compared in two contrasting Protected Natural Areas in Chiapas, Mexico: the Selva El Ocote Biosphere Reserve (REBISO), a wilderness area, and the El Zapotal Ecological and Recreational Center, an urban protected area with high visitor traffic. Camera traps were utilized for 102 days in REBISO (88 independent records) and 122 days in El Zapotal (140 independent records). Activity patterns were analyzed using the Overlap package in R, calculating the temporal overlap coefficient, and determining if there were significant differences between the activity periods of the two sites using the Mardia-Watson-Wheeler test. The species exhibited a diurnal pattern at both sites, with a high temporal overlap (Δ4 = 0.70; 95% CI = 0.60-0.80) but with significant differences (W = 13.643, P < 0.001). In REBISO, D. mexicana maintained continuous activity between 06:00 and 18:00 hours, with activity peaks between 06:00-08:00 and 13:00-14:00. At El Zapotal, a more pronounced bimodal pattern was observed, with peaks at dawn and dusk, significantly reducing activity during times of high human presence (09:00-16:00). The observed differences could be attributed to the influence of human presence, in addition to other factors such as habitat characteristics, presence of predators, and resource availability.
