Statistical Efficiency in Distance Sampling. [PDF]
Distance sampling is a technique for estimating the abundance of animals or other objects in a region, allowing for imperfect detection. This paper evaluates the statistical efficiency of the method when its assumptions are met, both theoretically and by

Mixture models for distance sampling detection functions. [PDF]
We present a new class of models for the detection function in distance sampling surveys of wildlife populations, based on finite mixtures of simple parametric key functions such as the half-normal.

Deriving observation distances for camera trap distance sampling [PDF]
AbstractCamera trap distance sampling (CTDS)o is a recently developed survey method to estimate animal abundance from camera trap data for unmarked populations. It requires the estimation of camera‐animal observation distances, which previously was done by comparing animal positions to reference labels at predefined intervals.

Free-Roaming Dog Surveys in Quito, Ecuador: Experiences, Lessons Learned, and Future Work
The selection of a survey method of free-roaming dog populations should be based on analyses of local capacities and management priorities. Here, we compare the results of surveys of the stray dog population in Quito, Ecuador, using two different ...
