Spatial capture-recapture models for search-encounter data
J. Andrew Royle, Marc Kery, Jerome Guelat
2011, Methods in Ecology and Evolution (2) 602-611
1. Spatial capture–recapture models make use of auxiliary data on capture location to provide density estimates for animal populations. Previously, models have been developed primarily for fixed trap arrays which define the observable locations of individuals by a set of discrete points. 2. Here, we develop a class of models...
