Can pipistrelles, Pipistrellus pipistrellus (Schreber, 1774) and Pipistrellus pygmaeus (Leach, 1825), foraging in a group, change parameters of their signals ?

Original language description

Echolocation behaviour and the structure of calls of Pipistrellus pygmaeus and P. pipistrellus were studied using a time expansion bat detector. Echolocation signals were recorded in the field in south-eastern Moravia and northern Bohemia (Czech Republic) and in an ad hoc experimental laboratory. For each of the species, multivariate analyses of variance indicated significant differences in calls produced inside the experimental room and in the open. Paired T-test and MANOVA were also used to reveal influences of inter-individual contacts in each of the cryptic species on the spectral patterns of call variables. Differences were found in the spectral variables of echolocation calls of an individual flying in the room alone and in a group of conspecifics. The possibility that bats use their flexibility to avoid mutual disturbances of echolocation calls was tested. We found that bats flying in a group modify the parameters of their echolocation signals according to the presence of other

Czech name

Mohou netopýři druhu Pipistrellus pipistrellus (Schreber, 1774) and Pipistrellus pygmaeus (Leach, 1825), lovící ve skupině, měnit parametry signálů?

Czech description

Byly zjištěny rozdíly mezi frekvenčními parametry echolokačních signálů u jedinců stejného druhu lovících ve skupině. naopak rozdíly nebyly zjištěny, pokud ve skupině lovily druhy odlišné. Schopnost posunu frekvenčních parametrů netopýrům zajišťuje minimalizaci v chybném rozeznámí vlastního echa.
