fk: number of individuals captured k times. S: number of distinct individuals captured. ptr: daily threshold capture probability for which 95% of individuals are expected to be included in the reference population. CV: coefficient of variation (degree of heterogeneity). LP: Lincoln-Petersen; MLP: Multiple Lincoln-Petersen; MPE: Mean Petersen estimate; IntJK: Interpolated jackknife; ME: Moment estimator; SC1: Sample coverage 1; SC2: Sample coverage 2; EE: Estimating equation.
The 95%-confidence interval is shown in brackets. Estimations that cover the reference population size are highlighted in bold.
