| Summary: | (Uploaded by Plazi for the Bat Literature Project) A rapid range expansion of Pipistrellus kuhlii (KUHL, 1817) can be observed throughout Europe based on new records gathered in the last two decades. Data of new occurrences were obtained by different methods (mist netting, dead specimens, checking buildings for roosts, etc.), providing only a rough picture about the exact pattern of the expansion. The aim of this study was to show an effective acoustic method that can be used for quantifying the differences in the occurrence of Pipistrellus kuhlii in two given areas or within the same area at different times. Therefore this method can be used to investigate the process of area expansion in this species. The large overlap in the echolocation call parameters of Pipistrellus kuhlii and Pipistrellus nathusii (KEYSERLING & BLASIUS, 1839) made it necessary to create a sound library from the calls of the two species. Discriminant function analysis (DFA) was used to classify the calls with 81.5% accuracy. We ... |
