Optimally designing drone‐based surveys for wildlife abundance estimation with N‐mixture models

Methods in Ecology and Evolution, Volume 14, Issue 3, Page 898-910, March 2023., 2023
Abstract Hierarchical N‐mixture models have been suggested for abundance estimation from spatiotemporally replicated drone‐based count surveys, since they allow modeling abundance of unmarked individuals while accounting for detection errors. However, it is still necessary to understand how these models perform in the wide variety of contexts and ...
