A stochastic measure of similarity between dolphin signature whistles
Bottlenose dolprlin (Tursiops trunratus) whistles are currently studied by subjective visual comparison of whistle spectrograms. This thesis describes the novel use of stochastic modeling to automate the comparison of dolphin whistles and to yield an objective, quantitative measure of whistle …

Development and functions of signature whistles of free-ranging bottlenose dolphins, Tursiops truncatus
… and functions of individually distinctive signature whistles of free-ranging bottlenose dolphins, Tursiops tnmcatus. Research was conducted at a study site near Sarasota, Florida, where a resident community of bottlenose dolphins have been the focus of a long-term, ongoing study. Through …

Investigating the potential for individually distinctive signature whistles to be used in mark-recapture of common bottlenose dolphins (Tursiops truncatus)
… the potential of using individually distinctive signature whistles of bottlenose dolphins, Tursiops truncatus. Acoustic and photo identification data were collected simultaneously from a small population of common bottlenose dolphins in Walvis Bay, Namibia, between 2009 and 2015. Visual …

Whistle use and whistle sharing by allied male bottlenose dolphins, Tursiops truncatus
… these alliances on vocal development. Comparing whistles produced in isolation revealed that alliance partners have similar whistles, while non-partners do not. Whistle similarity seen in alliance partners mirrors group-specific vocal convergence in stable groups of birds and bats. Males produce …

Who Said That? Towards a Machine-Prediction-Based Approach to Tursiops Truncatus Whistle Localization and Attribution in a Reverberant Dolphinarium
… research – research has fixated on "signature whistles," individually distinctive whistles that seem to convey an individual's identity to conspecifics, can be mimicked, and can be modulated under certain circumstances in ways that may or may not be communicative. Apart from signature …

The choreography of belonging : toothed whale spatial cohesion and acoustic communication
… between animals. Looking more specifically at signature whistles, a type of call often linked to cohesion, I found that when one animal produced its own signature whistle, its partner was more likely to respond with its own whistle. To better evaluate potential cohesion functions for signature …

Techniques for studying vocal learning in bottlenose dolphins, Tursiops truncatus
… Preliminary evidence has indicated that the signature whistles of dolphin calves are modeled on the whistles in the calves' early environments and that the calves' social interactions influence the choice of model. The methods currently used to study the acoustic and social behavior of …

Passive Acoustics: A Multifaceted Tool for Marine Mammal Conservation
… was examined using recorded noise and dolphin whistles. I found that bottlenose dolphins are able to compensate for increased noise in their environment using a wide range of strategies employed in a singular fashion or in various combinations, depending on the frequency content of the noise, …
