Techniques for studying vocal learning in bottlenose dolphins, Tursiops truncatus
… 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 learning is critical for the development of human language but plays a much smaller role in …

Does Personality Similarity in Bottlenose Dolphin Pairs Influence Dyadic Bond Characteristics?
<p>Social structures are critical to the success of many species and have repercussions on health, well-being, and adaptation, yet little is known about the factors which shape these structures aside from ecology and life history strategies. Dyadic bonds are the basis of all social structures; …

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
… to analyze the function 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 …

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
… to conduct continuous behavioral observations of bottlenose dolphins in the Sarasota Bay, FL area. This system allowed me to describe previously unreported foraging behaviors and elucidate functions for behaviors already defined but poorly understood. Dolphin foraging was modeled as a …

Diet Analysis of Stranded Bottlenose Dolphins (<i>Tursiops truncatus</i>) in Virginia
<p>This study 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 …

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

Personality and affiliation involving a cooperative task in bottlenose dolphin (Tursiops Truncatus) Dyads
Cooperation may 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 …

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>)
… states, in calf, juvenile, 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. …

Investigation into the Neurogenetics of Vocal Learning in Tursiops Truncatus, the Bottlenose Dolphin
… reference 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 …

An Examination of Aggressive Behavior in Indo-Pacific Bottlenose Dolphins (<i>Tursiops Aduncus</i>)
… have long-term relationships. Although bottlenose dolphins (Tursiops sp.) are known to behave aggressively, relatively little is known about such behavior among wild animals. Much of the data on delphiilid aggression comes from captive studies, and is likely biased by the limited space …

Effects of Failure on Subsequent Performance in the Bottlenose Dolphin (<i>Tursiops truncatus</i>)
… based 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 …
