Differences in echolocation calls of Pipistrellus pipistrellus (Schreber 1774) and Pipistrellus pygmaeus (Leach 1825) in allo- and syntopic foraging areas

Original language description

The changes in echolocation behaviour and the structure of calls of Pipistrellus pygmaeus and P. pipistrellus were studied in south-eastern Moravia and northern Bohemia (Czech Republic) in 2002 2004, between April and the half June (before weaning) usinga time expansion bat-detector. Some bats were also recorded in experimental laboratory conditions. We used multivariate analysis to distinguish influences of inter-individual and close conspecifics of each of both cryptic species on temporal and spectral pattern of call variables. The possibility that bats use their flexibility to avoid mutual disturbances of their echolocation calls was tested. This study was focused on signal adaptation and clarification of identification accuracy by bat detectors. Echolocation behaviour was influenced by the presence of conspecifics and individuals of second species. Individuals of P. pygmaeus emit signals with higher spectral variables during foraging in a group than during separate foraging. The r

Rozdíly v echolokačních hlasech Pipistrellus pipistrellus (Schreber 1774) a Pipistrellus pygmaeus (Leach 1825) na allo- a syntopickych lovištích

Czech description

Sledovali jsme změny paramtrů echolokačních signálů druhů Pipistrellus pygmaeus a P.pipistrellus z JV Moravy a východních Čech v letech 2002 2004. Někteří jedinci byli také nahráváni v laboratorních podmínkách.Pro odlišení změn vyvolaných přítomností jedince stejného nebo jiného druhu jsme použili multivariantních metod.
