Extended Data Table 1 The camera trap (CT) study periods with the focal chimpanzee community within Cantanhez National Park

  1. The number of distinct CT locations for that study period is included (total number of CT locations = 211). Certain CT locations were used in more than one study period (Supplementary Table 1). For targeted CT placement if no chimpanzees were filmed for a certain period CTs were repositioned; hence not all cameras were working at the same time. The placement design of CTs was targeted or systematic. Targeted CTs were deployed to maximize detection of chimpanzees (such as chimpanzee drumming sites, fruiting trees and trails). Systematic CTs were placed following a survey design maximizing independence between CT sites and chimpanzee detection. The CT mode was either set to photograph or video or both (hybrid) and CTs were active for 24 h per day. The start and end dates of each study period are included as well as the number of CT days. CT days are the sum of number of days for each active CT after removing days when cameras were inactive due to malfunctioning, batteries running out, trees falling in front of the CT or theft (total CT days = 28,993). The researcher initials are included (J.B., Joana Bessa; E.B., Elena Bersacola; M.R., Marina Ramon).
