| Summary: | Visual representation of foraging bouts and roost switches based on presence signals at bat boxes (base stations) and meeting data. (a) A foraging bout is characterized by an interrupt of the presence signals of an individual bat which are received by a base station at a specific roost (in this case base station 1). Usually, variation of the received signal strength indicator (RSSI) increases when a bat is leaving a roost compared to when it is roosting (notice the pronounced spike upon departure and return). (b) A roost switch among two monitored sites is displayed. The presence signals interrupt at base station 2 while the strong variation in RSSI indicates that the bat is flying. Presence signals are then received by base station 1. (c) A roost switch occurs among an unmonitored to a monitored site. Roosting at the unmonitored site is indicated by stable meetings among three bat individuals (dashed/solid/dotted lines). Meetings interrupt when a bat individual leaves the unmonitored site followed by presence signals being received by the base station at the monitored site. |
