  1. K is the number of estimated parameters in the model and ΔAIC is the absolute difference in AIC values relative to the model with the smallest AIC. Weight means AIC weight; neg2ll = the value of twice the negative log-likelihood. SP means species effect on detection or occupancy, INT_o = the occurrence of dominant species changes the detection or occupancy probability of the other subordinate species, INT_d = the detection of dominant species changes the detection or occupancy probability of the subordinate species in the same survey, SP:INT_o means occurrence of two species change the detection probability interactively. The term “EVI_dry” in parentheses denotes that the detection probability of species was estimated for enhanced vegetation index in the dry season, “EVI_wet” means enhanced vegetation index in the wet season, “Distance” means the nearest distance to the resident settlement, “Coverage” means forest canopy coverage, “Elevation” means the mean elevation of each grid cell, and “Slope” means the mean slope of each grid cell
