Similarity in spatial utilization distributions measured by the Earth Mover's Distance

Abstract

Estimating the similarity in space use (spatio-temporal home range overlap) of animals is important formany questions regarding behavioural ecology, wildlife management and conservation. The current methods that calculate joint space use generally do not account for proximity in space use, as all of them rely on the differences between the exact spatial overlay of utilization distributions, while spatial distances between distributions should be considered to truly quantify similarity.
