SUMMARY:

White-lipped peccaries (Tayassu pecari) and collared peccaries (Dicotyles tajacu) are Neotropical ungulates of high ecological importance, playing key roles in tropical forest dynamics, but have experienced population declines due to forest fragmentation, habitat loss, and anthropogenic pressures, particularly in the Amazon. This study integratively analyzed the influence of environmental and anthropogenic variables on the occurrence, relative abundance, and activity patterns of these species in the Sete de Setembro Indigenous Land (TISS), Rondônia, aiming to support management and conservation strategies in Indigenous territories. A systematic literature review following the PRISMA protocol was conducted to identify key environmental and anthropogenic drivers of T. pecari and D. tajacu occurrence and gaps in existing studies. In parallel, camera trap data from the TISS were analyzed to estimate relative abundance and characterize daily activity patterns and temporal overlap using independent records and circular statistics. Environmental and land-use variables derived from remote sensing, including vegetation structure and landscape metrics, were evaluated at multiple spatial scales using quantitative models. The results showed a higher number of independent records for D. tajacu, suggesting greater relative occurrence or detectability, while T. pecari was less frequently recorded. Both species were predominantly diurnal, with D. tajacu showing a clearly diurnal pattern and T. pecari a cathemeral pattern with greater temporal concentration of activity. Despite high temporal overlap, differences in daily time use were evident. The literature synthesis and multiscale analyses indicated that forest integrity, resource availability, and anthropogenic pressure strongly influence species occurrence, with T. pecari being more sensitive to habitat loss and fragmentation and D. tajacu more tolerant of heterogeneous landscapes. Integrating temporal, spatial, and environmental information enhances understanding of the ecology of these species and provides critical insights for their conservation in Amazonian Indigenous territories.
