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

Animal 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 ...

Evaluating wildlife rehabilitation: successful return of rehabilitated gulls to the wildEvaluating wildlife rehabilitation: successful return of rehabilitated gulls to the wild [PDF]

Royal Society Open Science
The expansion of human activities has increased the need for animal rehabilitation, especially for urban-breeding species such as herring gulls (Larus argentatus) and lesser black-backed gulls (Larus fuscus), which now commonly nest on buildings and ...

Study on the population structure of the paradoxical frog, Pseudis bolbodactyla (Amphibia: Anura: Hylidae), using natural markings for individual identification

Zoologia (Curitiba), 2013
The goal of this study was to assess the population structure of Pseudis bolbodactyla Lutz, 1925 using natural markings to identify individuals. Recruitment, survival, and population size estimations were obtained using the Jolly-Seber stochastic method.

The Influence of Mark-Recapture Sampling Effort on Estimates of Rock Lobster Survival. [PDF]

PLoS ONE, 2016
Five annual capture-mark-recapture surveys on Jasus edwardsii were used to evaluate the effect of sample size and fishing effort on the precision of estimated survival probability. Datasets of different numbers of individual lobsters (ranging from 200 to

An integrated model of territory occupancy and mark‐recapture data for estimating spatial variation in survival

Methods in Ecology and Evolution, EarlyView.
Abstract Spatial variation in survival is central to understanding population dynamics and guiding conservation. However, assessing it is hard, since capture‐mark‐recapture (CMR) data required for such inference must be collected over large spatial extents, which is seldom possible.

Reproduction, growth rate and dispersal of the dark chub, Candidia sieboldii, as estimated by using the mark–release–recapture method

Journal of Freshwater Ecology, 2017
We investigated the breeding season, growth rate and dispersal of the dark chub, Candidia sieboldii, an endangered species in Japan. A mark–release–recapture survey was performed in three branches of the Ishizu River system in Osaka Prefecture, Japan ...

Complete tag loss in capture–recapture studies affects abundance estimates: An elephant seal case study

Ecology and Evolution, 2020
In capture–recapture studies, recycled individuals occur when individuals lose all of their tags and are recaptured as though they were new individuals. Typically, the effect of these recycled individuals is assumed negligible. Through a simulation‐based

Balancing Fire Regimes and Population Dynamics for the Conservation of a Microendemic Lizard From a Biodiversity Hotspot

Animal Conservation, EarlyView.
Disturbance from fire mediates a potential ecophysiological trade‐off between adult performance and juvenile recruitment in the microendemic lizard Ameivula jalapensis. While open, burned habitats enhance adult thermoregulation and condition, unburned patches remain critical for juvenile thermal optima.
