Table 3 Estimated exponential rates of population growth (\(r\)) of the southern bent-winged bat at Bat Cave, Naracoorte, Australia. Estimates of \(r\) are calculated from a pre-breeding Leslie matrix parameterised using apparent annual survival rates for each study year (Supplementary Table S5, using the top-ranked model presented in Table 2) and assuming reproductive maturity of adult females at two years of age and additional parameters as specified. If parameters are not listed, they remain at the baseline parameterisation.
