First record of a Nathusius’ pipistrelle (Pipistrellus nathusii) overwintering at a latitude above 60°N

Nathusius' pipistrelle bats (Pipistrellus nathusii, Keyserling & Blasius 1839) breeding in Ireland

We describe the most westerly known maternity colony of Nathusius' pipistrelle bats (Pipistrellus nathusii). The bats were identi®ed by using morphometric measurements and analysis of time-expanded echolocation and social calls. The roost, containing approximately 150 individuals, was located in a mid 19th century farm stable block and store house situated in parkland in County Antrim, Northern...

Arrhythmic breathing in torpid pipistrelle bats, Pipistrellus pipistrellus.

The arrhythmic breathing pattern of torpid female pipistrelle bats (Pipistrellus pipistrellus) was monitored using Doppler radar. A total of 98 h of radar measurements were made on 11 individuals over 17 experiments, during which time 974 apneic intervals were monitored, over ambient temperatures (Ta, degrees C) ranging from -1 to 14 degrees C, and body masses ranging from 4.6 to 7.4 g. As Ta d...

Scanning Behavior in Echolocating Common Pipistrelle Bats (Pipistrellus pipistrellus)

Echolocating bats construct an auditory world sequentially by analyzing successive pulse-echo pairs. Many other mammals rely upon a visual world, acquired by sequential foveal fixations connected by visual gaze saccades. We investigated the scanning behavior of bats and compared it to visual scanning. We assumed that each pulse-echo pair evaluation corresponds to a foveal fixation and that sona...

Histological and Histochemical Analysis of the Gastrointestinal Tract of the Common Pipistrelle Bat (Pipistrellus Pipistrellus)

Bats have a very high mass-specific energy demand due to small size and active flight. European bat species are mostly insectivorous and the morphology of the gastrointestinal tract should be adapted accordingly. This study investigated the general anatomy by histology and the function by analysing carbohydrate distribution in particular of the mucus of the GI tract of the insectivorous bat Pip...
