Brian D. Gerber and Robert P. Parmenter. 2015. Spatial capture–recapture model performance with known small-mammal densities. Ecological Applications 25:695–705. http://dx.doi.org/10.1890/14-0960.1
Appendix A. Summary of small-mammal capture–recapture data for 11 populations, including the number of unique individuals captured, recaptures, trap saturation, and movement metrics.
Table A1. Summary of trapping small-mammals using a trapping grid and web in enclosures with known population sizes. Populations were identified by species or groups of species; groups of species were aggregated to a population due to small sample size and taxonomic similarity.
