Parameter redundancy in Jolly‐Seber tag loss models [PDF]

open access: yesEcology and Evolution, 2021
Capture–recapture experiments are conducted to estimate population parameters such as population size, survival rates, and capture rates. Typically, individuals are captured and given unique tags, then recaptured over several time periods with the ...

Understanding the impact of correlation within pair‐bonds on Cormack–Jolly–Seber models [PDF]

open access: yesEcology and Evolution, 2021
The Cormack–Jolly–Seber (CJS) model and its extensions have been widely applied to the study of animal survival rates in open populations. The model assumes that individuals within the population of interest have independent fates. It is, however, highly

Age-structured Jolly-Seber model expands inference and improves parameter estimation from capture-recapture data. [PDF]

open access: yesPLoS ONE, 2021
Understanding the influence of individual attributes on demographic processes is a key objective of wildlife population studies. Capture-recapture and age data are commonly collected to investigate hypotheses about survival, reproduction, and viability ...

Survival Estimation Using Multistate Cormack–Jolly–Seber Models—The Case of the Bearded Vulture Gypaetus barbatus in Spain [PDF]

open access: yesAnimals
The bearded vulture (Gypaetus barbatus) is an endangered species with a specialist osteophagous (bone) diet. We estimated the survival and productivity of this vulture in the Aragonese Pyrenees, where the main population of the species in Europe is found.

Continuous time-dependent individual covariates and the Cormack-Jolly-Seber model

open access: yesAnimal Biodiversity and Conservation, 2007
Covariantes continuas individuales dependientes del tiempo y el modelo de Cormack-Jolly-Seber El modelo de Cormack–Jolly–Seber proporciona el marco básico para analizar la supervivencia de animales en poblaciones abiertas utilizando datos de captura ...

A comparison of abundance estimates from extended batch-marking and Jolly-Seber-type experiments. [PDF]

open access: yesEcol Evol, 2014
AbstractLittle attention has been paid to the use of multi‐sample batch‐marking studies, as it is generally assumed that an individual's capture history is necessary for fully efficient estimates. However, recently, Huggins et al. () present a pseudo‐likelihood for a multi‐sample batch‐marking study where they used estimating equations to solve for ...

Population Dynamics of the Florida Softshell Turtle (Apalone ferox) in a Protected Spring Ecosystem [PDF]

open access: yesBiology
The Florida softshell turtle, Apalone ferox, is considered common and found in many different types of freshwater habitats throughout its range. However, despite its prevalence where it occurs, little is understood about the species’ life history and ...

Continuous time-dependent Individual covariates and the Cormack-Jolly-Seber model [PDF]

open access: yesAnimal Biodiversity and Conservation, 2004
The Cormack-Jolly-Seber model provides the basic framework for analyzing the survival of animals in open populations using capture-recapture data. Extensions of this model have already been developed that allow the survival and capture probabilities to ...

Using Known Births to Account for Delayed Marking in Population Estimation of North Atlantic Right Whales [PDF]

open access: yesEcology and Evolution
Population estimation using capture–recapture modeling typically requires that individuals are identifiable by unique marks. North Atlantic right whales (Eubalaena glacialis) can be identified by natural callosity patterns on their heads that are ...
