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 ...

Persistence of a declining anuran species across its distribution. [PDF]

open access: yesPLoS ONE
Information on a species' population dynamics, such as changes in abundance and distribution, can be used to identify declining populations and initiate conservation efforts and protections.

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 ...

Cormack–Jolly–Seber models: time and age perspectives [PDF]

open access: yesStochastic Environmental Research and Risk Assessment, 2020
Survival is a key demographic characteristic in many areas including both human demography and population ecology. However, it is often the case that data collection protocols are different in these areas, resulting in different models and methods of analysis.

Estimating abundance of Eastern Canada-West Greenland bowhead whales using genetic mark-recapture analyses

open access: yesGlobal Ecology and Conservation, 2023
The Eastern Canada-West Greenland (EC-WG) bowhead whale (Balaena mysticetus) population is widely distributed across the eastern Canadian Arctic and across Baffin Bay to the western coast of Greenland.

Bayesian analysis of Jolly-Seber type models [PDF]

open access: yesEnvironmental and Ecological Statistics, 2016
We propose the use of finite mixtures of continuous distributions in modelling the process by which new individuals, that arrive in groups, become part of a wildlife population. We demonstrate this approach using a data set of migrating semipalmated sandpipers (Calidris pussila) for which we extend existing stopover models to allow for individuals to ...

Providing evidence for the conservation of a rare forest butterfly: Results from a three-year capture-mark-recapture study

open access: yesBasic and Applied Ecology, 2023
Species living in spatially structured populations require a network of interconnected habitat patches. Due to changes in forest management, this network of habitat patches has been lost for insect species inhabiting open spots within forests. We studied

The abundance of large, piscivorous Ferox Trout (Salmo trutta) in Loch Rannoch, Scotland [PDF]

open access: yesPeerJ, 2016
Background Ferox Trout are large, long-lived piscivorous Brown Trout (Salmo trutta). Due to their exceptionally large size, Ferox Trout are highly sought after by anglers while their life-history strategy, which includes delayed maturation, multiphasic ...
