(Uploaded by Plazi for the Bat Literature Project) Variation in the number of bats in maternity roosts of two phonic types of P.pipistrellus was investigated. Also, bats of the two phonic types were caught at maternity roosts, and their wing morphology and echolocation calls studied. 45 kHz P. pipistrellus maternity roosts contained significantly fewer bats than 55 kHz P.pipistrellus roosts. There was significant variation in mean frequency of maximum energy (FMAXE) of echolocation calls used by bats among roosts of 55 kHz P. pipistrellus, but not among roosts of 45 kHz P.pipistrellus. However, within each phonic type differences among roosts only accounted for a small proportion of the variation in echolocation call frequency; a much larger proportion was due to differences among individuals. Forearm length, an indicator of body size, was larger in 45 kHz P. pipistrellus than in 55 kHz P.pipistrellus, but there was no relationship between body size and geographic roost location in either phonic type. ...
