A negative exponential decay model was generated from transect calibration points, with all habitat types combined (i.e., null model). Transects ran in a random cardinal direction from two randomly chosen nodes per habitat type at distances of 2, 5, 10, 20, 50, 75, and 100 m from the node. Receiver signal strength (RSS) and distance of a radio tag from a node were collected in a managed pine barren in western Massachusetts (USA) in summer 2022
