Estimating jaguar densities with camera traps: problems with current designs and recommendations for future studies
MW Tobler, GVN Powell - Biological conservation, 2013 - Elsevier
Camera traps have become the main method for estimating jaguar (Panthera onca)

Shooting for abundance: Comparing integrated multi‐sampling models for camera trap and hair trap data
Abundance estimation is a vital goal in wildlife monitoring. Camera‐traps are a tool to survey
wildlife populations noninvasively and can be used for abundance estimation if individuals …

Evaluating heterogeneity of sex‐specific capture probability and precision in camera‐trap population estimates of tigers
Population estimates of tigers (Panthers tigris) are affected by movement patterns of the
sexes. We evaluated sex‐specific heterogeneity to estimate the tiger population at …

Using camera-trap technology to improve undergraduate education and citizen-science contributions in wildlife research
M Karlin, G De La Paz - The Southwestern Naturalist, 2015 - BioOne
We performed a pilot study to determine whether camera traps were an effective means for
establishing a baseline of species richness, distribution, and abundance at a state natural …

Double-observer approach with camera traps can correct imperfect detection and improve the accuracy of density estimation of unmarked animal populations
Y Nakashima, S Hongo, K Mizuno, G Yajima… - Scientific Reports, 2022 - nature.com
Camera traps are a powerful tool for wildlife surveys. However, camera traps may not always
detect animals passing in front. This constraint may create a substantial bias in estimating …

Modeling abundance, distribution, movement and space use with camera and telemetry data
RB Chandler, DA Crawford, EP Garrison, KV Miller… - Ecology, 2022 - Wiley Online Library
Studies of animal abundance and distribution are often conducted independently of
research on movement, despite the important links between processes. Movement can …
