Sampling variables and their thresholds for the precise estimation of wild felid population density with camera traps and spatial capture–recapture methods

open access: yesMammal Review, 2023
1 . Robust monitoring, providing information on population status, is fundamental for successful conservation planning. However, this can be hard to achieve for species that are elusive and occur at low densities, such as felids.

Efficient estimation of large‐scale spatial capture–recapture models

open access: yesEcosphere, 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.

Extracting spatial networks from capture–recapture data reveals individual site fidelity patterns within a marine mammal’s spatial range

open access: yesEcology 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 ...

The use of camera traps to study the hooded skunk Mephitismacroura (Carnivora: Mephitidae) abundance

open access: yesCaldasia, 2023
Skunks are important for the ecosystems as consumers of fruits, seeds, and insects. The hooded skunk (Mephitis macroura) is a medium-sized mammal common in North America, but its abundance is poorly known throughout its range.

An open spatial capture-recapture framework for estimating the abundance and seasonal dynamics of white sharks at aggregation sites

open access: yesMarine Ecology Progress Series, 2023
: The present study provides the first estimate of abundance for the white shark at a new ag - gregation site in the western North Atlantic, which re quired the development of a novel modeling framework to accommodate the species’ migratory behavior ...

Modelling spatially autocorrelated detection probabilities in spatial capture-recapture using random effects [PDF]

open access: yesbioRxiv, 2022
Spatial capture-recapture (SCR) models are now widely used for estimating density from repeated individual spatial encounters. SCR accounts for the inherent spatial autocorrelation in individual detections by modelling detection probabilities as a ...

Integrating telemetry data at several scales with spatial capture–recapture to improve density estimates

open access: yesEcosphere, 2021
Accurate population estimates are essential for monitoring and managing wildlife populations. Mark–recapture sampling methods have regularly been used to estimate population parameters for rare and cryptic species, including the federally listed Mojave ...

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.

An Experimental Test of Buffer Utility as a Technique for Managing Pool-Breeding Amphibians [PDF]

open access: yes, 2015
Vegetated buffers are used extensively to manage wetland-dependent wildlife. Despite widespread application, buffer utility has not been experimentally validated for most species.
