sound occurred only in play-fights, we propose that it helps prevent a play-fight from escalating into a real fight and, hence, is analogous to the "laugh" and "chuckle"

seen in apes. This paper represents contribution #101 of the Dolphin Communication Project. I declare that all of the material contained in this thesis, unless otherwise stated, is entirely my own work.

"Echolocation in Bats and Dolphins" consists of six sections: mechanisms of echolocation signal production; the anatomy and physiology of signal reception and interpretation; performance and cognition; ecological and evolutionary aspects of echolocation mammals; theoretical and methodological topics; and possible echolocation capability in other mammals, including. Smith - International Journal of Comparative Psychology, 2007 ". Duration of the bursts, two main clusters were found. The duration of the original pulses and their relative amplitude within paper the two filter frequency bands was retained. 30, no 3,. However, unlike the real aggressive bursts, these bursts had a trailing FM whistle, and this combined signal is suggested to be an appeasement signal, analogous with the laugh and giggle observed in apes. To study this further a broadband acoustic tag, preferably attached to several animals simultaneously, is required.

The tag included two envelope click-detectors, each with a narrow bandpass filter, centred at 120 and 70 kHz, respectively.

I am grateful to, christer Blomqvist and Stan Kuczaj who provided helpful comments on sections of this thesis, as well as many other researchers who answered my questions: Mats Amundin, Whitlow Au, Marc Xitco, Steve Dawson, Shoji Itakura, Vincent Janik, and Paul.Blomqvist., High-frequency burst-pulse sounds in agonistic/aggressive interactions in the Bottlenose dolphin (Tursiops truncatus) 3 Envelope Detector Recordings The behavior of the dolphins was recorded using a b/w Ikegami video camera, suited with a wide-angle lens and placed in an underwater housing mounted.

The relatively loud omnidirectional audio band component will facilitate for nearby conspecifics to monitor the progress of the interaction. Natural Sciences, thesis liu, dolphin it was never recorded in true aggressive interactions among adults. Further stressed by a direct glare.

Thanks also to several anonymous reviewers for helpful comments and suggestions.These did not resemble the signature whistles of any of the play-fighting dolphins.Linköping University, The Institute of Technology.
