Název v původním jazyce

Variability in echolocation calls of Pipistrellus pygmaeus (Chiroptera: Vespertilionidae) during search flight in different habitats

Popis výsledku v původním jazyce

The changes in echolocation behaviour and the structure of calls of Pipistrellus pygmaeus (Leach, 1825) were studied in different habitats of a floodplain forest in south-eastern Moravia (Czech Republic) in 20012002. Calls (403 observations) were recorded in different sites between April and mid June (before weaning) using a time expansion bat-detector. Three signals per individual were analysed and descriptive statistics of variables of calls were presented. Association of signal types with habitat structure (cluttered, sidecluttered, semi-cluttered and uncluttered space) was found in echolocation sequences of the search phase of flight. P. pygmaeus used mainly narrowband signals (bandwidths less than 15 kHz) in uncluttered space and wideband signals(more than 15 kHz) in cluttered space. Almost 6% of the inter pulse intervals of signals were twice (or more) longer than usual inter pulse intervals (mainly in uncluttered space). In general, temporal variables of signals reached higher
