Jolly-Seber models in MARK
نویسندگان
چکیده
The original Jolly-Seber (JS) model (Jolly, 1965; Seber, 1965) was primarily interested in estimating abundance. Since then, the focus of many mark-recapture experiments changed to estimating survival rates (but not abundance) using the Cormack-Jolly-Seber (CJS)models (Cormack, 1964; Jolly, 1965; Seber, 1965)particularlywith the publication of Lebreton et al. (1992). In previous chapters concerning analysis of live encounterdata,we have focussed exclusively onCJSmodels. In recent years,however, interest has returned to estimating parameters related to abundance such as population growth (λi), recruitment ( fi), as well as abundance (Ni). * Much of the theory about estimating population growth, recruitment, and abundance can be found in Williams et al. (2002).

Constant-parameter capture-recapture models.
Jolly (1982, Biometrics 38, 301-321) presented modifications of the Jolly-Seber model for capture-recapture data, which assume constant survival and/or capture rates. Where appropriate, because of the reduced number of parameters, these models lead to more efficient estimators than the Jolly-Seber model. The tests to compare models given by Jolly do not make complete use of the data, and we pre...
متن کاملPlausible combinations: An improved method to evaluate the covariate structure of Cormack-Jolly-Seber mark-recapture models
Mark-recapture models are extensively used in quantitative population ecology, providing estimates of population vital rates, such as survival, that are difficult to obtain using other methods. Vital rates are commonly modeled as functions of explanatory covariates, adding considerable flexibility to mark-recapture models, but also increasing the subjectivity and complexity of the modeling proc...

Estimation of Demographic Parameters from Live-Encounter Data: a Summary Review
Estimation of demographic parameters is central to research questions in wildlife management, conservation, and evolutionary ecology. I review the 7 major classes of mark–recapture models that investigators can use to estimate apparent survival and other parameters from live-encounter data. Return rates are the product of 4 probabilities: true survival (S), site fidelity (F), site propensity (d...
متن کاملJoint Analysis of Live and Dead Encounters of Marked Animals
Recently developed methods for analyzing mark–recapture data allow simultaneous modeling of information from a variety of animal encounters. Incorporating this extra information in an analysis requires use of a more complicated model but can lead to improved precision of estimates. An important aspect of such joint models is that movement of animals to and from the banding site can be incorpora...
