MODELING CAPTURE, RECAPTURE, AND REMOVAL STATISTICS FOR ESTIMATION OF DEMOGRAPHIC PARAMETERS FOR FISH AND WILDLIFE POPULATIONS - PAST, PRESENT, AND FUTURE

In this article I review the modeling of capture, recapture, and removal statistics for the purpose of estimating demographic parameters of fish and wildlife populations. Topics considered include capture-recapture models, band or tag return models, removal and catch per unit effort models, selective removal or change-in-ratio models, radio-tagging survival models, and nest survival models. The purpose is to present important concepts in a general manner for the benefit of a wide audience of statisticians. I will not attempt to be comprehensive, and I indulge in speculation about future directions. I indicate the importance of different statistical tools to this subject, such as Bayesian inference, "boot strapping," robustness studies, goodness-of-fit tests. I also emphasize connections to other application areas of statistics. Capture-recapture methods, for example, are being considered for estimation of a variety of elusive human populations, such as the homeless and people missed in the census. Survival analysis, widely used in medicine and engineering, can also be applied to radio-tagged animals.
