Techniques for studying vocal learning in bottlenose dolphins, Tursiops truncatus
The objective of this thesis is to develop the methods necessary for evaluating the role of learning in the natural whistle development of bottlenose dolphins. Bottlenose dolphins provide a unique opportunity to study social influences on vocal learning in a highly social non-human mammal. Vocal …

Age-related Aspects of Mirror-use by Bottlenose Dolphins (Tursiops truncatus)
<p>Bottlenose dolphins are neuroanatomically different and evolutionarily divergent from primates yet they exhibit mirror self-recognition (MSR), a rare cognitive ability in non-human animals. This research investigated the developmental and age-related aspects of MSR in this species. During a …

Relating behavioral context to acoustic parameters of bottlenose dolphin (Tursiops truncatus) vocalizations
… of vocalizations of the bottlenose dolphin, Tursiops truncatus. The thesis uses the social interaction as the basic unit of analysis, and maintains a deliberate focus on quantitative and replicable analyses throughout. A method for determining identity of the vocalizing animal in a lagoon was …

Whistle use and whistle sharing by allied male bottlenose dolphins, Tursiops truncatus
Male dolphins form stable, long-term alliances comparable to long-term relationships formed by terrestrial species. The goal of this thesis was to determine the effect of the formation of these alliances on vocal development. Comparing whistles produced in isolation revealed that alliance partners …

Sound use, sequential behavior and ecology of foraging bottlenose dolphins, Tursiops truncatus
Odontocetes are assumed to use echolocation for navigation and foraging, but neither of these uses of biosonar has been conclusively demonstrated in free-ranging animals. Many bats are known to use echolocation throughout foraging sequences, changing the structure and timing of clicks as they …

Diet Analysis of Stranded Bottlenose Dolphins (<i>Tursiops truncatus</i>) in Virginia
… describes the diet of bottlenose dolphins (<em>Tursiops truncatus</em>) stranded in Virginia via stomach content analysis and considers factors such as proportion of numerical abundance and reconstructed mass, frequency of occurrence, average reconstructed prey size, prey diversity and quantity, …

Development and functions of signature whistles of free-ranging bottlenose dolphins, Tursiops truncatus
… 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 observations and censuses, researchers have gained …

Personality and affiliation involving a cooperative task in bottlenose dolphin (Tursiops Truncatus) Dyads
… be related to personality in bottlenose dolphin (Tursiops truncatus) dyads. Five bottlenose dolphin pairs at the Roatan Institute for Marine Sciences (RIMS), Honduras, were presented with an apparatus released a food reward if opened cooperatively. I created personality profiles of each dolphin …

Vocal Response of Bottlenose Dolphins (<i>Tursiops truncatus</i>) to a Novel Stimulus
<p>Bottlenose dolphins utilize acoustic signals as their primary mode of communication. Although some aspects of dolphin vocal behavior are well understood, less is known about vocalizations in different behavioral contexts and how these vocal behaviors may indicate habituation and sensitization. …

Solitary and Social Object Play in the Bottlenose Dolphin (<i>Tursiops truncatus</i>)
… subadult, and adult bottlenose dolphins (<em>Tursiops truncatus</em>). While juveniles engaged in solitary play significantly more than any other age group, both juveniles and calves engaged in observer and social play significantly more than adults and subadults. Within their own age group, …

Investigation into the Neurogenetics of Vocal Learning in Tursiops Truncatus, the Bottlenose Dolphin
… genome assembly for the bottlenose dolphin (<em>Tursiops truncatus</em>). Bottlenose dolphins are well-documented learners that share significant phenotypic overlap with human language development. Using a trio binning approach developed by the Vertebrate Genome Project (VGP), in which samples …

Effects of Failure on Subsequent Performance in the Bottlenose Dolphin (<i>Tursiops truncatus</i>)
… training sessions in 11 bottlenose dolphins (<em>Tursiops truncatus</em>) at the U.S. Navy Marine Mammal Program in San Diego, CA. While learning a multi-faceted behavior not commonly found in nature, such as beaching, animals are likely to perform approximations of the behavior that are not …
