... impact the biosonar strategies and source parameters implemented by an echolocating animal in time and space. In toothed whales, the importance of context on biosonar adjustments is largely unknown. To address this, we trained two harbour porpoises to actively approach the same sound recording target...

...Michael Ladegaard; Jason Mulsow; Dorian S. Houser; Frants Havmand Jensen; Mark Johnson; Peter Teglberg Madsen; James J. Finneran ABSTRACT Echolocating toothed whales generally adjust click intensity and rate according to target range to ensure that echoes from targets of interest arrive before...

...Michael Ladegaard; Frants Havmand Jensen; Kristian Beedholm; Vera Maria Ferreira da Silva; Peter Teglberg Madsen ABSTRACT Toothed whales have evolved to live in extremely different habitats and yet they all rely strongly on echolocation for finding and catching prey. Such biosonar-based foraging...

...Michael Ladegaard; Frants Havmand Jensen; Mafalda de Freitas; Vera Maria Ferreira da Silva; Peter Teglberg Madsen ABSTRACT Toothed whales produce echolocation clicks with source parameters related to body size; however, it may be equally important to consider the influence of habitat, as suggested...

...Gina L. Lonati; Andrew J. Westgate; D. Ann Pabst; Heather N. Koopman ABSTRACT Understanding toothed whale (odontocete) diving gas dynamics is important given the recent atypical mass strandings of odontocetes (particularly beaked whales) associated with mid-frequency naval sonar. Some stranded...

...Peter T. Madsen; Marc Lammers; Danuta Wisniewska; Kristian Beedholm SUMMARY Toothed whales produce sound in their nasal complex by pneumatic actuation of phonic lip pairs within the blowhole. It has been hypothesized that dual actuation of the phonic lip pairs can generate two pulses that merge...

..., as an active sensory system, may provide more opportunities to control such information flow by adjusting the properties of the sound source. However, most studies of toothed whale echolocation have involved stationed animals in static auditory scenes for which dynamic information control is unnecessary...

...Maria Wilson; Henriette B. Schack; Peter Teglberg Madsen; Annemarie Surlykke; Magnus Wahlberg SUMMARY Toothed whales emit high-powered ultrasonic clicks to echolocate a wide range of prey. It may be hypothesized that some of their prey species have evolved capabilities to detect and respond...

...P. T. Madsen; D. Wisniewska; K. Beedholm SUMMARY Echolocating toothed whales produce high-powered clicks by pneumatic actuation of phonic lips in their nasal complexes. All non-physeteroid toothed whales have two pairs of phonic lips allowing many of these species to produce both whistles...
