Forecasting wildlife movement with spatial capture–recapture

open access: yesMethods in Ecology and Evolution, 2023
Wildlife movement is an important process affecting species population biology and community interactions in myriad ways. Studies of wildlife movement have focused on retrospectively estimating movements of small numbers of individuals by outfitting them

A Generalized Estimating Equations Approach to Model Heterogeneity and Time Dependence in Capture-Recapture Studies [PDF]

open access: yes, 2017
Individual heterogeneity in capture probabilities and time dependence are fundamentally important for estimating the closed animal population parameters in capture-recapture studies.

Using the capture-recapture method to estimate the human immunodeficiency virus-positive population [PDF]

open access: yesEpidemiology and Health, 2017
OBJECTIVES The capture-recapture method was applied to estimate the number of human immunodeficiency virus (HIV)-positive individuals not registered with any data sources. METHODS This cross-sectional study was conducted in Lorestan Province, in the west

A spatial capture-recapture model for territorial species [PDF]

open access: yes, 2014
Advances in field techniques have lead to an increase in spatially-referenced capture-recapture data to estimate a species' population size as well as other demographic parameters and patterns of space usage.

Full Open Population Capture-Recapture Models with Individual Covariates [PDF]

open access: yes, 2010
Traditional analyses of capture-recapture data are based on likelihood functions that explicitly integrate out all missing data. We use a complete data likelihood (CDL) to show how a wide range of capture-recapture models can be easily fitted using ...

Probit models for capture-recapture data subject to imperfect detection, individual heterogeneity and misidentification [PDF]

open access: yes, 2014
As noninvasive sampling techniques for animal populations have become more popular, there has been increasing interest in the development of capture-recapture models that can accommodate both imperfect detection and misidentification of individuals (e.g.,

A Comparison of Grizzly Bear Demographic Parameters Estimated from Non-Spatial and Spatial Open Population Capture-Recapture Models.

open access: yesPLoS ONE, 2015
Capture-recapture studies are frequently used to monitor the status and trends of wildlife populations. Detection histories from individual animals are used to estimate probability of detection and abundance or density.

Trap configuration and spacing influences parameter estimates in spatial capture-recapture models. [PDF]

open access: yesPLoS ONE, 2014
An increasing number of studies employ spatial capture-recapture models to estimate population size, but there has been limited research on how different spatial sampling designs and trap configurations influence parameter estimators.
