From: How do non-independent host movements affect spatio-temporal disease dynamics? Partitioning the contributions of spatial overlap and correlated movements to transmission risk

A The average per cell CSR(x) for 147 season by pair combinations of white-tailed deer for varying levels of home range overlap among individuals (given by the Bhattacharyya coefficient, BC; higher value means higher home range overlap). The size of points indicates the relative number of contacts (individuals within 40 m of each other) per area of overlap per unit time of collar overlap. Bigger points mean more interactions per unit area per unit time. Only pairs with \(BC > 0.2\) are included on this plot. B, C Seasonal trends in the average per cell CSR(x) for a female–female pair (B) and a male-male pair (C). Blue lines give the observed average per cell CSR(x) for each pair in each season and gray points give the distribution of points from 200 temporal randomizations of host movement trajectories to remove non-independent movement [38]. If observed blue points do not overlap with the gray points, non-independent movements are contributing substantially more to transmission risk than spatial overlap. Numbers above each point give the Bhattacharyya coefficient for home range overlap for that particular pair and season
