Časové změny v aktivitě Pipistrellus pipistrellus v blízkosti úkrytu v Hranické propasti (Česká republika)
Original language description
Research of common pipistrelles, Pipistrellus pipistrellus, was carried out in the Hranická Chasm in 2008. It was focused on the overnight changes in activity during 17 monitored nights from April to November. Recordings of echolocation calls acquired byautomatic ultrasound detection afforded the main data source. The bat-detector and DAT recorder were always situated on the same detecting point located below the top edge of the chasm and recordings usually proceeded continually over the night. The length of the night was limited by the time of sunset and sunrise. Each night was divided into eighths and the season of monitoring into five periods related to the reproductive cycle of bats. Relative activity defined as the number of minutes with the record of bat calls related to an hour of recording (min+/hour) reached the peak in July while it was the lowest in April.
