From spatial orientation to food acquisition in echolocating bats
Field research on echolocation behavior in bats has emphasized studies of food acquisition, and the adaptive value of sonar signal design as been considered largely in the context of foraging.Expand

The roles of echolocation and olfaction in two Neotropical fruit-eating bats, Carollia perspicillata and C. castanea, feeding on Piper
Abstract We studied the echolocation and foraging behavior of two Neotropical frugivorous leaf-nosed bats (Carollia perspicillata, C. castanea: Phyllostomidae) in a flight cage. To test which cuesExpand

Auditory fovea and Doppler shift compensation: adaptations for flutter detection in echolocating bats using CF-FM signals
Rhythmical modulations in insect echoes caused by the moving wings of fluttering insects are behaviourally relevant information for bats emitting CF-FM signals with a high duty cycle. Transmitter andExpand

Bat guilds, a concept to classify the highly diverse foraging and echolocation behaviors of microchiropteran bats
Throughout evolution the foraging and echolocation behaviors as well as the motor systems of bats have been adapted to the tasks they have to perform while searching and acquiring food. When batsExpand

Echolocation signals reflect niche differentiation in five sympatric congeneric bat species
Echolocating bats can be divided into guilds according to their preferred habitat and foraging behaviour, which coincide with distinct adaptations in wing morphology and structure of echolocationExpand

Echolocation behavior and signal plasticity in the Neotropical bat Myotis nigricans (Schinz, 1821) (Vespertilionidae): a convergent case with European species of Pipistrellus?
Abstract. We used both field and flight cage observations to investigate the echolocation and foraging behavior of the seldom studied, small, aerial insectivorous bat Myotis nigricansExpand

Suppression of distortion product otoacoustic emissions (DPOAE) near 2f1−f2 removes DP-gram fine structure—Evidence for a secondary generator
Since the discovery of distortion product otoacoustic emissions (DPOAE) there has been a controversial discussion about their cochlear generation sites. Suppression experiments suggest that the placeExpand

Estimation of the acoustic range of bat echolocation for extended targets.
Extended natural structures of the bat environment such as trees, meadows, and water surfaces were ensonified in distances from 1 to 20 m and the echoes recorded using a mobile ultrasonic sonarExpand
