High jaguar densities and large population sizes in the core habitat of the southwestern Amazon (2013, methodology): “…it has been argued that placing cameras on trails and roads can lead to biased estimates due to different individual preferences for these features (Foster and Harmsen, 2012), we believe that the gain in data greatly outweighs the potential bias introduced, especially if detection probability is…”
The history of wildlife camera trapping as a survey tool in Australia (2015, background): “In order to accurately understand data and report on findings it is crucial that the weaknesses and nuances of camera traps are realised, a concern also raised by Foster and Harmsen (2012), who declared their concern about the misuse of camera traps in field studies.”
Comparison of density estimation methods for mammal populations with camera traps in the Kaa‐Iya del Gran Chaco landscape (2012, methodology): “We concur with the recommendation for using simulation studies to guide study design and evaluate the performance of SCR estimators prior to implementing field work (Foster & Harmsen, 2012).”
"Which camera trap type and how many do I need?" A review of camera features and study designs for a range of wildlife research applications (2013, background): “Study design needs to consider both the spacing of traps relative to individual movement, and the total size and shape of the trap array (Foster and Harmsen, 2011).”
Towards good practice guidance in using camera‐traps in ecology: influence of sampling design on validity of ecological inferences (2013, background): “Several other studies also emphasized on the factors affecting trapping efficiency and sensitivity such as sex, species, season and camera position (Rowcliffe et al. 2008, 2011; Guil et al. 2010; Harmsen, Foster & Doncaster 2011; Foster & Harmsen 2012).”
Estimating jaguar densities with camera traps: Problems with current designs and recommendations for future studies (2013, methodology): “While placing cameras in optimal locations could favor certain individuals over others (Foster and Harmsen, 2012), in our experience cameras that are randomly placed in the landscape have a very low capture probability for jaguars and will result in poor data.”
