Abstract In southern Sweden, densities of northern bats Eptesicus nilssonii (Keyserling & Blasius) flying along artificially lit roads in built-up areas (villages) were assessed, by using an ultrasound detector, at 2-5 bats per kilometre. In comparison, there were 0.1-0.4 bats per kilometre of u...

| Summary: | Abstract In southern Sweden, densities of northern bats Eptesicus nilssonii (Keyserling & Blasius) flying along artificially lit roads in built-up areas (villages) were assessed, by using an ultrasound detector, at 2-5 bats per kilometre. In comparison, there were 0.1-0.4 bats per kilometre of unlit road. Means of 3.2 and 3.l common pipistrelle bats Pipistrellus pipistrellus (Schreber) were recorded per kilometre of lit road in England and Scotland respectively. |
