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

Evaluating camera survey methods for estimating wild turkey abundance
Accurately estimating population parameters rests on methodological approaches that provide unbiased, cost‐effective estimates; however, assessing accuracy of estimates can be vexing as true abundance is rarely known.

Demography and Behaviour of Teinopodagrion oscillans (Odonata: Megapodagrionidae) in a Protected Area of the Colombian Andean Region [PDF]
The demography and behaviour of Teinopodagrion oscillans was studied in a protected area in the Andean region of Colombia. Adult damselflies were individually marked, and using their recapture histories, we estimated survival, longevity, sex ratio, and ...

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

Apparent Survival of Territorial Golden Eagles Using Non-Invasive Genetic Profiling. [PDF]
In a novel study for the species, DNA was extracted from moulted feathers over 4 years involving 21% of the Scottish population of territorial golden eagles, and individuals' genetic profiles were analysed for apparent survival rates. Results showed sexual differences but not between two sub‐populations; very few cases of breeding dispersal were ...

Bayesian analysis of Jolly-Seber type models [PDF]
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 ...
