Table 3.

Parameter estimates for two-species occupancy models where A represents the dominant species and B the subdominant species. Occupancy estimates for species B are listed along with their 95 % confidence intervals. Parameters are: occupancy of species B when A is present (ψ ^BA), occupancy of species B when A is absent (ψ ^Ba) and occupancy of species B regardless of species A occupancy (ψ ^B). Estimates are not comparable across species pairs (rows).
