University of Bergamo, Bergamo, Italy ABSTRACT We propose a novel approach for modeling capture-recapture (CR) data on open populations that exhibit temporary emigration, while also accounting for individual heterogeneity to allow for differences in visit patterns and capture probabilities between individua...
Capture–recaptureCombinatorialHypergeometricIt is shown that, in the capture鈥搑ecapture method, the widely used formulae of Bailey or Chapman-Seber give the most likely value for the size of the population, but systematically underestimate the probability that the population is larger than any ...
The total number (N) of individuals living in the environment can then be estimated by proportionality, using the following formula: N = n1 x n2 / n3 However, since the recapture of individuals is random, the number of individuals bearing the mark can fluctuate significantly from one campaign...

This article discusses identifiability and maximum likelihood estimation for a closed population capture-recapture model with heterogeneity in capture probabilities. The model assumes that the individual capture probabilities arise from a discrete distribution over the interval [Inline formula] Considering the ...
In order to evaluate these estimators, they are applied to real, three-source, capture-recapture data. By conditioning on each of the sources of three source data, we have been able to compare the estimators with the true value that they are estimating. The Chapman and Chao estimators were ...

Limitations Marking or capturing the animal might change its behavior to avoid recapture The mark might be toxic or cause predators to see it Marks might cause the animal to be rejected by its own population Trapping might cause the animal to avoid the traps in the future or to choose to be...
