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 …

A systematic approach to measuring the social behavior of bottlenose dolphins
… of systematic methodologies to better understand bottlenose dolphin social relations. Samuels and Gifford adapted a quantitative technique from primate behavioral research to study agonism among captive dolphins. Males were dominant to females; females had stable, age-ordered dominance relations; …

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 …

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, …

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. …

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 …

Same-Sex Socio-Sexual Interactions Among a Group of Captive Bottlenose Dolphins (<i>Tursiops truncatus</i>)
<p>Bottlenose dolphins (<em>Tursiops truncatus</em>) frequently engage in non-reproductive sexual behavior, including homosexual encounters. In order to better understand the nature and function of these interactions, a longitudinal study of the patterns of association and the dynamics of …

Site Fidelity and Association Patterns of Bottlenose Dolphins (<i>Tursiops truncatus</i> in the Mississippi Sound
… association patterns of a community of 678 wild bottlenose dolphins (Tursiops truncatus) in the Mississippi Sound (Sound) over a three-year period (May 2004 - April 2007). Using photoidentification techniques, 74% (n = 498) of the identified dolphins were classified as transients, while 10% (n = …

Life History Parameters and Social Associations of Female Bottlenose Dolphins (Tursiops Truncatus) in North Carolina, USA
… I describe the seasonality of reproduction in bottlenose dolphins by examining data from stranded animals, photographic surveys and focal follows. I examined inter-birth intervals from focal follows of known female dolphins. I found bottlenose dolphins that frequent the coastal waters of North …

Using Personality Traits to Predict Pectoral Fin Contact Initiation Role in Bottlenose Dolphins (<i>Tursiops truncatus</i>)
… and maintenance of social relationships between dolphins (Dudzinski & Ribic, 2017). Additionally, several studies have shown that bottlenose dolphins have distinct personalities that are consistent across time and situation (e.g., Highfill & Kuczaj, 2007; Kuczaj, Highfill, & Byerly, 2012), and it …

Characterization of Association Patterns of Coastal Migratory Bottlenose Dolphins, <i>Tursiops truncatus</i>, in the Nearshore Waters of Virginia Beach, Virginia
<p>Bottlenose dolphins, <em>Tursiops truncatus</em>, commonly occur in fission-fusion social systems. For this study, I analyzed photo-identification data from 1994 to 1999 to describe association patterns of bottlenose dolphins in the nearshore waters of Virginia Beach, Virginia. Bottlenose …

Establishing a Link Between Personality and Social Rank in a Group of Bottlenose Dolphins (<i>Tursiops truncatus</i>)
<p>Bottlenose dolphins (<em>Tursiops truncatus</em>) have been documented to possess personality traits that remain consistent over time (Highfill & Kuczaj, 2007) and across contexts (Kuczaj, Highfill, & Byerly, 2012). Such individual differences are thought to play an important role in various …

Estimating the Cost of Locomotion in Common Bottlenose Dolphins: Calibration, Validation, and Application to Study the Impacts of Disturbance
… with the long-term resident community of common bottlenose dolphins (Tursiops truncatus) living in Sarasota Bay, Florida, which experiences very high levels of traffic from small vessels. I first correlated overall dynamic body acceleration (ODBA) and energy expenditure with bottlenose dolphins …
