We consider two basic live-recapture models referred to as the CJS model (after Cormack–Jolly–Seber) that models the tagged data, and the JS model (after Jolly and Seber in Biometrika, 52:225–247, 1965), which also includes the untagged data. Likelihood methods as originally used are described, while Bayesian and random-effects methods have since been ...

Multistate Mark-Recapture Model Selection Using Score Tests
Biometrics, 2010Although multistate mark-recapture models are recognized as important, they lack a simple model-selection procedure. This article proposes and evaluates a step-up approach to select appropriate models for multistate mark-recapture data using score tests.

Mark–recapture studies and demography
2008AbstractPopulation ecologists track wild animals over their lifetimes using mark-recapture methods. Odonates are easily marked and remain near water bodies, allowing for high recapture rates. In recent years, the focus in mark-recapture models has switched from population size estimates to survival and recapture rate estimation, and from testing ...

Trap mortality in mark-recapture studies
Environmental and Ecological Statistics, 2009When animals die in traps in a mark-recapture study, straightforward likelihood inferences are possible in a class of models. The class includes M0, Mt, and Mb as reported by White et al. (Los Alamos National Laboratory, LA-8787-NERP, pp 235, 1982), those that do not involve heterogeneity.

Variances of Mark-Recapture Estimates
Biometrics, 1993When mark-recapture data are analysed by log-linear models, as described by Cormack (1989, Biometrics 45, 395-413), the analysis is in terms of parameters that are related nonlinearly to the parameters of biological interest. For several models formulae are given expressing the variance of the interesting parameter estimates in terms of those provided ...

Inferring species interactions through joint mark–recapture analysis
Ecology, 2018AbstractIntroduced species are frequently implicated in declines of native species. In many cases, however, evidence linking introduced species to native declines is weak. Failure to make strong inferences regarding the role of introduced species can hamper attempts to predict population viability and delay effective management responses.

Mark-Recapture Estimation of a Salmon Smolt Population
Biometrics, 1994A mark-recapture experiment was conducted applying a two-sample stratified technique to estimate the number of Atlantic salmon smolts, Salmo salar, migrating out of the Conne River, Newfoundland. We developed a model where parameters are introduced to describe the mean time for the salmon to migrate between the release site and recapture site and to ...

Mark—recapture methods were originally developed for estimating the size of mobile animal populations. However, it was soon recognized that the same methods could be used for estimating survival rates in the wild. It was then a short step to using the same approach for comparing the survival rates of different morphs in a polymorphic population.

Tag loss and the Petersen mark-recapture experiment
Biometrika, 1981SUMMARY A problem in the Petersen capture-mark-recapture experiment (Seber, 1973, Chapter 3) is the possible loss of tags. The effect of such a loss on the usual estimate of population size and the estimate of its variance is investigated for both single and double tagging.
