Constant-Parameter Capture-Recapture Models [PDF]

open access: yesBiometrics, 1986
Jolly (1982, Biometrics 38, 301-321) presented modifications of the Jolly-Seber model for capture-recapture data, which assume constant survival and/or capture rates. Where appropriate, because of the reduced number of parameters, these models lead to more efficient estimators than the Jolly-Seber model.

Performance of spatial capture-recapture models with repurposed data: Assessing estimator robustness for retrospective applications.

open access: yesPLoS ONE, 2020
Advancements in statistical ecology offer the opportunity to gain further inferences from existing data with minimal financial cost. Spatial capture-recapture (SCR) models extend traditional capture-recapture models to incorporate spatial position of ...

Population density of sitatunga in riverine wetland habitats

open access: yesGlobal Ecology and Conservation, 2020
Estimates of population density of mammals are critical data for effective management. Estimating density is complicated if the species of interest has cryptic markings and occupies dense habitat.

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 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.

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

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 ...

Co-integration analysis of capture–recapture method in toad, Phrynoidis aspera (Gravenhorst, 1829)

open access: yesJournal of Asia-Pacific Biodiversity, 2019
The Asian giant toad, Phrynoidis aspera, research is faced mainly with twin challenges of conservation and efficient sampling techniques for research purposes.

State space and movement specification in open population spatial capture-recapture models. [PDF]

open access: yes, 2018
With continued global changes, such as climate change, biodiversity loss, and habitat fragmentation, the need for assessment of long-term population dynamics and population monitoring of threatened species is growing.
