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 concer...
population and density estimate of black rat in mangrove forests was conducted by two independent procedures, including seber-jolly and catch-effort methods. a selected trapping area with 15 hectares was studied. first, 60 cage traps for seber-jolly and then 80 cage traps for catch-effort method installed in the trapping area. we used color earrings and numerical rings for marking the captured ...
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...
We develop an approach to utilize anisotropic metamaterials to solve one of the fundamental problems of modern plasmonics--parasitic scattering of surface waves into free-space modes, opening the road to truly two-dimensional plasmonic optics. We illustrate the developed formalism on the examples of plasmonic refractor and plasmonic crystal, and discuss limitations of the developed technique an...
Capture–recapture experiments are conducted to estimate population parameters such as size, survival rates, and capture rates. Typically, individuals captured given unique tags, then recaptured over several time periods with the assumption that these tags not lost. However, for some populations, tag loss cannot be assumed negligible. The Jolly-Seber model is used when no-tag-loss invalid. Furth...
Estimation of abundance is important in both open and closed population capture-recapture analysis, but unmodeled heterogeneity of capture probability leads to negative bias in abundance estimates. This article defines and develops a suite of open population capture-recapture models using finite mixtures to model heterogeneity of capture and survival probabilities. Model comparisons and paramet...
