| Summary: | (Uploaded by Plazi for the Bat Literature Project) Bat populations may be vulnerable to the barrier impacts of roads, including habitat restriction and traffic mortality. Under-road passageways may reduce these impacts, but little is known about the ecological factors influencing their use by bats. The study area provided a natural experimental design, in that adjacent under-motorway passageways had contrasting dimensions (two long, narrow drainage pipes within <1 km of a large underpass for a minor road), and local bat species had contrasting functional and morphological adaptations. We predicted that inter-species differences in flight capability and sensory perception would influence bat use of passageways. All-night acoustic recordings of bat activity inside passageways (52 nights) indicated clear guild-specific responses to passageway dimensions. Only Rhinolophus hipposideros, Myotis nattereri and Plecotus auritus flew through the narrow drainage pipes. These species are adapted for flight and ... |
