Abundance estimates from the four Jolly-Seber models fitted to mark-recapture data for the entire Moreton Bay (MB) as well as for each sub-population (South and North) over all field seasons.

The fully time-dependent models were selected as most appropriate (highlighted in bold) based on AICc values and evidence of heterogeneity in capture and survival probabilities as well as survey effort. AICc = corrected Akaike Information Criterion; φ = survival probability; p = capture probability; (t) = time dependent effect; (.) = constant effect; Nmarked = estimated number of marked animals over all field seasons; Ntotal = estimated total population size (adjusting for proportion of identifiable individuals).
