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.

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

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.

ipsecr: An R package for awkward spatial capture–recapture data
Methods in Ecology and Evolution, 2023 Some capture–recapture models for population estimation cannot easily be fitted by the usual methods (maximum likelihood and Markov‐chain Monte Carlo).

Peer Community JournalSpatially explicit capture–recapture models are used widely to estimate the density of animal populations. The population is represented by an inhomogeneous Poisson point process, where each point is the activity centre of an individual and density ...

Ghostbusting—Reducing bias due to identification errors in spatial capture‐recapture histories
Methods in Ecology and EvolutionIdentifying individuals is key to estimating population sizes by spatial capture–recapture, but identification errors are sometimes made. The most common identification error is the failure to recognise a previously detected individual, thus creating a ...

Spatial capture‐recapture can improve environmental impact assessments for large carnivores
Ecological Solutions and EvidenceEnvironmental Impact Assessments (EIAs) for large carnivores frequently rely on summary statistics or relative abundance indices to evaluate the effects of infrastructure development on predator populations.

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 ...

Ecosphere, 2023 Estimating population density is critical for effective species conservation, wildlife management planning, and long‐term monitoring. Obtaining accurate estimates is especially important for the wolf (Canis lupus), a widely distributed northern ...
