Chapter 10 - Estimation of Survival, Recruitment, and Population Size from Capture–Recapture Data Using the Jolly–Seber Model

Abstract

Capture–recapture data from an open population contain more demographic information than just about survival, as utilized by the Cormack–Jolly–Seber model. These data also contain information about recruitment and population size, and this information is exploited by the Jolly–Seber (JS) model. Estimation of all these quantities is possible because the JS model does not condition on first capture but also models the events prior to and including first capture. There are many different parameterizations of the JS model, and here we describe three: we write the Jolly–Seber model as a restricted occupancy model, as a multistate model, and using a superpopulation approach. As we did for closed-population estimation, we make extensive use of parameter-expanded data augmentation for implementation of the JS model.
