Display song of parti-coloured bat Vespertilio murinus Linnaeus, 1758 (Chiroptera, Mammalia) in southern Slovenia and preliminary study of its variability

In September 2000, display song of parti-coloured bat Vespertilio murinus Linnaeus, 1758, was recorded for the first time in Slovenia. Bats emitted the song at four localities near Goteniška gora Mountain in southern Slovenia while flying above the canopy or above open land surrounded by forests. In...

Description
Summary:In September 2000, display song of parti-coloured bat Vespertilio murinus Linnaeus, 1758, was recorded for the first time in Slovenia. Bats emitted the song at four localities near Goteniška gora Mountain in southern Slovenia while flying above the canopy or above open land surrounded by forests. In thearea of Medvedjak, the display song consisted of 8 frequency modulated sweeps on average and a final frequency modulated - quasi-constant frequency call (average frequency of maximum energy in quasi-constant frequency part of the final call was 14.69 kHz). Final calls of the display song from three localities were significantly different in four measured parameters. Possible causes for this are discussed. Septembra 2000 je bil prvič v Sloveniji posnet svatbeni napev dvobarvnega netopirja Vespertilio murinus Linnaeus, 1758. Na štirih lokalitetah pri Goteniški gori (južna Slovenija) so se netopirji oglašali med letom nad krošnjami ali odprtimi jasami, obdanimi z gozdom. Svatbeni napev z Medvedjaka je bil sestavljen iz povprečno 8 frekvenčno moduliranih klicev in končnega frekvenčno moduliranega - kvazi-konstantno frekvenčnega klica (povprečna frekvenca z maksimalno energijo v kvazi-konstantno frekvenčnem delu končnega klica je bila 14,69 kHz). Končni klici svatbenih napevov s treh lokalitet so bili v štirih merjenih parametrih statistično značilno različni. Obravnavani so možni vzroki za različnosti.
