Results of simulation studies of a paired release-recapture design (Figure 1) when all survival and detection parameters are homogeneous across release groups except S ₁₃ ≠ S ₂₃. In this case, models M ₄ to M ₇ are invalid. Detection probabilities were simulated at either P = 0.90 or 0.95 at all locations.
