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

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

Spatial capture-recapture design and modelling for the study of small mammals. [PDF]
PLoS ONE, 2018 Spatial capture-recapture modelling (SCR) is a powerful analytical tool to estimate density and derive information on space use and behaviour of elusive animals. Yet, SCR has been seldom applied to the study of ecologically keystone small mammals.

Simulation-based validation of spatial capture-recapture models: A case study using mountain lions. [PDF]
PLoS ONE, 2019 Spatial capture-recapture (SCR) models have improved the ability to estimate densities of rare and elusive animals. However, SCR models have seldom been validated even as model formulations diversify and expand to incorporate new sampling methods and/or ...

Bayes and empirical Bayes estimators of abundance and density from spatial capture-recapture data. [PDF]
PLoS ONE, 2013 In capture-recapture and mark-resight surveys, movements of individuals both within and between sampling periods can alter the susceptibility of individuals to detection over the region of sampling.

Forecasting wildlife movement with spatial capture–recapture
Methods 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

Population density of sitatunga in riverine wetland habitats
Global 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.

Integrating dead recoveries in open‐population spatial capture–recapture models
Ecosphere, 2021 Integrating dead recoveries into capture–recapture models can improve inference on demographic parameters. But dead‐recovery data do not only inform on individual fates; they also contain information about individual locations.

Efficient estimation of large‐scale spatial capture–recapture models
Ecosphere, 2021 Capture–recapture methods are a common tool in ecological statistics, which have been extended to spatial capture–recapture models for data accompanied by location information.

Ecology and Evolution, 2022 Estimating the impacts of anthropogenic disturbances requires an understanding of the habitat‐use patterns of individuals within a population. This is especially the case when disturbances are localized within a population's spatial range, as variation ...
