Average annual home range overlap indices (± CI) for 11 timber rattlesnakes (Crotalus horridus; n = 20 home range overlaps) tracked for two or more years in Jersey County Il. Overlap of home ranges calculated using the Brownian Bridge Movement Model (BBMM; for 99%, 95% and 50% isopleths) were quantified using Bhattacharyya’s affinity (BA; A), the Utilization Distribution Overlap Index (UDOI; B), and simple isopleth overlaps (i.e., dividing the area of intersection between two given home range isopleths by the total combined area of both isopleths; C). The latter metric was also used to calculate overlap of home ranges calculated via Minimum Convex Polygons (MCP; D)
