Mark-Recapture and Mark-Resight Methods for Estimating Abundance with Remote Cameras: A Carnivore Case Study
Abundance estimation of carnivore populations is difficult and has prompted the use of non-invasive detection methods, such as remotely-triggered cameras, to collect data. To analyze photo data, studies focusing on carnivores with unique pelage patterns have utilized a mark-recapture framework and studies of carnivores without unique pelage patterns have used a mark-resight framework. We compar...
متن کاملA spatial mark--resight model augmented with telemetry data.
Abundance and population density are fundamental pieces of information for population ecology and species conservation, but they are difficult to estimate for rare and elusive species. Mark--resight models are popular for estimating population abundance because they are less invasive and expensive than traditional mark-recapture. However, density estimation using mark-resight is difficult becau...
متن کاملA general model for the analysis of mark-resight, mark-recapture, and band-recovery data under tag loss.
Estimates of waterfowl demographic parameters often come from resighting studies where birds fit with individually identifiable neck collars are resighted at a distance. Concerns have been raised about the effects of collar loss on parameter estimates, and the reliability of extrapolating from collared individuals to the population. Models previously proposed to account for collar loss do not a...
متن کاملIdentification and Estimation of Incomplete Information Games with Multiple Equilibria∗
The presence of multiple equilibria in games is a big challenge for identification and estimation. Without information of the equilibrium selection, it is impossible to perform counterfactual analysis. Allowing for possibly multiple equilibria, this paper provides nonparametric identification of finite games with incomplete information. Upon observing players’ actions from cross-sectional games...
متن کاملUsing novel spatial mark–resight techniques to monitor resident Canada geese in a suburban environment
Context. Over the past two decades, an increase in the number of resident (non-migratory) Canada geese (Branta canadensis) in the United States has heightened the awareness of human–goose interactions. Aims. Accordingly, baseline demographic estimates for goose populations are needed to help better understand the ecology of Canada geese in suburban areas. Methods. As a basis for monitoring effo...
