Table 3. Top models and estimation of species interaction factor (SIF, γ^) for each species pair from two species occupancy modeling.

The species abbreviations of species’ names are LC-leopard cat, MPC-masked palm civet, HB-hog badger, SW-Siberian weasel, and YTM-yellow-throated marten. 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. The term “S” in parentheses denotes that the occupancy probability or detection probability of species were estimated separately for each species, and “·” indicates that the parameter is constant. Absence of γ(·) in the model notation implies that γ = 1 and absence of r(S) implies r(S) = p(S). “Lr” refers to scent lure persistence; and “Cam” refer to camera trap models.
