How does spatial study design influence density estimates from spatial capture-recapture models? [PDF]
PLoS ONE, 2012 When estimating population density from data collected on non-invasive detector arrays, recently developed spatial capture-recapture (SCR) models present an advance over non-spatial models by accounting for individual movement.

Testing the consistency of wildlife data types before combining them: the case of camera traps and telemetry. [PDF]
, 2014 Wildlife data gathered by different monitoring techniques are often combined to estimate animal density. However, methods to check whether different types of data provide consistent information (i.e., can information from one data type be used to predict

iDNA from terrestrial haematophagous leeches as a wildlife surveying and monitoring tool - prospects, pitfalls and avenues to be developed [PDF]
, 2015 Invertebrate-derived DNA (iDNA) from terrestrial haematophagous leeches has recently been proposed as a powerful non-invasive tool with which to detect vertebrate species and thus to survey their populations.

An Experimental Test of Buffer Utility as a Technique for Managing Pool-Breeding Amphibians [PDF]
, 2015 Vegetated buffers are used extensively to manage wetland-dependent wildlife. Despite widespread application, buffer utility has not been experimentally validated for most species.

Face Value: Towards Robust Estimates of Snow Leopard Densities. [PDF]
PLoS ONE, 2015 When densities of large carnivores fall below certain thresholds, dramatic ecological effects can follow, leading to oversimplified ecosystems. Understanding the population status of such species remains a major challenge as they occur in low densities ...

Estimating Wildlife Density as a Function of Environmental Heterogeneity Using Unmarked Data
Remote Sensing, 2022 Recent developments to spatial-capture recapture models have allowed their use on species whose members are not uniquely identifiable from photographs by including individual identity as a latent, unobserved variable in the model.

Best practices for reporting individual identification using camera trap photographs
Global Ecology and Conservation, 2020 Camera traps have become a popular sampling tool in ecological studies. This is especially true for studies that estimate population densities through spatial capture-recapture models of species with physical traits allowing individual identification ...
