Graphical description of the three deployed scenarios to test WildScope. The path followed by each mobile logger is described by a line of a different colour. The sequence of contemporary actions is represented by letters, whereas numbers indicate different loggers. Scenario 1: one mobile logger moving towards two fixed loggers (mimic of focal resource use) (box 1, upper left); scenario 2: two mobile loggers (mimic of encounter and avoidance movements) and two fixed loggers (box 2, upper right); scenario 3: three mobile loggers (mimic of parallel and random movements) and two fixed loggers (box 3, bottom left). The shaded circles represent the expected range of contact detection for the fixed loggers (stars) at the two power settings (dark-shaded small circle: power 3; light-shaded large circle: power 7). The radii of these circles, which are not reported here on the proper scale, were derived from the outcome of previous tests [8]. The dark green circles represent trees and bushes of various sizes in the arena where we performed the experiments
