Innovative mammal conservation
Over the past 50 years European populations of the lesser horseshoe bat have severely declined. To date, studies of the foraging behaviour of this species have been limited as its low mass (4±8 g) precluded the use of radio-telemetry because commercially available radio-transmitters exceeded 10% of its body mass. In this study, radiotransmitters weighing < 0.35 g were built.
