D = population density in independent leopards per 100 km2, σ = distance term for the detection function (km), α = conditional probability of a simultaneous type 1 and type 2 encounter (given both mark types detected), δ = conditional probability of type 1 (left flank) or type 2 (right flank), p and c = probabilities of capture and recapture respectively, ψ = probability that a randomly selected individual from the M = observed individuals belongs to the n unique individuals encountered at least once. To investigate the effect of sex, the best performing model for each area as mod.p = ~c + Time (Sarigol and Salouk) and mod.p = ˜c + Placement (Tandoureh) were run for each sex separately.
