Attachment of radio transmitters, after the clipping of the fur, and release of the bats: A) Hair clipping in the back of a L. aurita individual; B) gluing of the transmitter to the back of a L. aurita individual; C) Transmitter glued on and D) hand release. E) Hair clipping in the back of a F. horrens individual; B) gluing of the transmitter to the back of a F. horrens individual; C) Transmitter glued on, and D) hand release. All images were taken by the authors.

Summary of results obtained per species.
Species/Individuals, Sex, Forearm (length in mm), Cave, Treatment, Date, Season, Days (sampled) and N (Number of locations estimated). MCP (ha)–Minimal Convex Polygon estimate. KF 95% (ha)–Fixed Kernel estimates of range use with 95% (ha) of samples; KF 50% (ha)–Fixed Kernel estimates of range use with 50% (ha) of samples; MC 95% (m)–Maximum linear distance travelled from cave entrance in KF 95%; MC 50% (m)–Maximum linear distance travelled from the cave entrance to core foraging areas in KF 50%. At the bottom of each species, we present the average and standard deviation of estimates for each parameter related to the use of space.

Effects of landscape composition and seasonality for the combined estimates of the foraging areas of F. horrens and L. aurita considering fixed kernel estimates, KF 95% (a) and the KF 50% (b), and the Maximum commuting distances in KF95% (c) and in KF50% (d).
