Vocal Response Of Bottlenose Dolphins (Tursiops Truncatus) To A Novel Stimulus, Lindsey Johnson Aug 2019

Vocal Response Of Bottlenose Dolphins (Tursiops Truncatus) To A Novel Stimulus, Lindsey Johnson

Master's Theses

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. The focus of this study was to investigate how bottlenose dolphins respond vocally to a novel stimulus. Archival data from three populations of bottlenose dolphins (N = 20) living in a human-care facility were exposed to a novel apparatus (a mirror) for 10 trials, each lasting 20 minutes. Five of the trials presented the mirror covered with an opaque …


First Thirty Days Of Life: Examining Calf Behavioral Development In Beluga Whales (Delphinapterus Leucas) And Pacific White-Sided Dolphins (Lagenorhyncus Obliquidens) At One Zoological Facility, Kendal Smith May 2019

First Thirty Days Of Life: Examining Calf Behavioral Development In Beluga Whales (Delphinapterus Leucas) And Pacific White-Sided Dolphins (Lagenorhyncus Obliquidens) At One Zoological Facility, Kendal Smith

Master's Theses

Cetacean development is important for general comparative understanding and the implementation of informed husbandry policies. Due to the inaccessibility of many of these species in the wild, researchers can study managed care populations to better understand basic developmental patterns of cetaceans, as well as to improve husbandry policies for facility animals. However, no previous studies have attempted to observe the behavioral development of Pacific white-sided dolphins (Lagenorhyncus obliquidens). Eight beluga whale calves and four Pacific white-sided dolphin calves were observed for the first 30 days of life to determine the developmental trajectory of several typically monitored behaviors. The …


Using Personality Traits To Predict Pectoral Fin Contact Initiation Role In Bottlenose Dolphins (Tursiops Truncatus), Riley Paige Macgregor Dec 2018

Using Personality Traits To Predict Pectoral Fin Contact Initiation Role In Bottlenose Dolphins (Tursiops Truncatus), Riley Paige Macgregor

Master's Theses

Contact with the pectoral fin facilitates formation 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 has been suggested that these individual differences (i.e., personality) may influence tactile behavior exchanges. The current study therefore aimed to determine if bottlenose dolphin personality traits predict whether and how dolphins initiate contact as a rubber or rubbee during pectoral fin contact exchanges, and to identify whether the effects of personality traits …


Development Of Semantic Reference For Location Symbols By Bottlenose Dolphins (Tursiops Truncatus) Using A Two-Way Communication Keyboard, Alyssa Taylor Aug 2018

Development Of Semantic Reference For Location Symbols By Bottlenose Dolphins (Tursiops Truncatus) Using A Two-Way Communication Keyboard, Alyssa Taylor

Master's Theses

The ability for humans to communicate with another species has been an aspiration and well documented. One example is through training animals to make associations between a designated cue and conditioned response (Pryor, 1986). Two-way communication, however, in which both species can express wants/needs has been predominantly pursued with apes and dolphins. Studies conducted by Louis Herman demonstrated the capabilities of dolphins to comprehend complex semantic and syntactic commands in an artificial language system (Herman, Richards, & Wolz, 1984). Researchers working with primates have used American Sign Language, a computer keyboard system with discrete lexigrams, and a portable lexigram keyboard …


The Conundrum Of Causal Reasoning In Elephants, Beri Brown May 2018

The Conundrum Of Causal Reasoning In Elephants, Beri Brown

Master's Theses

Causal reasoning is marked by the ability to mentally reconstruct the missing part of a sequence in order to reproduce an outcome. While research on causal reasoning has been done with children, the results of the studies have been inconsistent. A standardized paradigm for comparative causal reasoning studies does not exist. Nissani (2006) investigated causal reasoning in a tool-use task with elephants and concluded that elephants were not capable of causal reasoning. The current study, a modified replication, yielded results that were not congruent with Nissani’s (2006) manuscript. Additionally, it was very unlikely that the Nissani (2006) study truly looked …


Do Pinnipeds Have Personality? Coding Harbor Seal (Phoca Vitulina) And California Sea Lion (Zalophus Californianus) Behavior Across Contexts, Amber J. De Vere May 2017

Do Pinnipeds Have Personality? Coding Harbor Seal (Phoca Vitulina) And California Sea Lion (Zalophus Californianus) Behavior Across Contexts, Amber J. De Vere

Master's Theses

Personality has now been studied in species as diverse as chimpanzees (King & Figueredo, 1997) and cuttlefish (Carere et al., 2015), but marine mammals remain vastly underrepresented in this area. A broad range of traits have been assessed only in the bottlenose dolphin (Highfilll & Kuczaj, 2007), while consistent individual differences in a few specific behaviors have been identified in grey seals (Robinson et al., 2015; Twiss & Franklin, 2010; Twiss, Culloch & Pomeroy, 2011; Twiss, Cairns, Culloch, Richards & Pomeroy, 2012). Furthermore, the context component of definitions of personality is not often assessed, despite evidence that animals may show …


Sparking A Dolphin's Curiosity: Individual Differences In Dolphins' Reactions To Surprising And Expectation-Violating Events, Malin Katarina Lilley May 2017

Sparking A Dolphin's Curiosity: Individual Differences In Dolphins' Reactions To Surprising And Expectation-Violating Events, Malin Katarina Lilley

Master's Theses

Non-scientific literature consistently describes dolphins as “curious animals,” but there has been little systematic research on curiosity in dolphins. Curiosity in humans and certain non-human animal species, including birds and non-human primates, has been studied by examining individual differences in exploration and reactions to novel stimuli. Additionally, research has explored how human infants and non-human animals react when an event violates their expectations. The present study explored dolphins’ reactions to spontaneously surprising and expectation-violating stimuli. The reactions of dolphins, 15 bottlenose (Tursiops truncatus) and 6 rough-toothed (Steno bredanensis), at Gulf World Marine Park were analyzed in …


Towards A Better Understanding Of Zebrafish Sleep Behavior, Kanza Musarrat Khan May 2017

Towards A Better Understanding Of Zebrafish Sleep Behavior, Kanza Musarrat Khan

Master's Theses

Sleep serves many vital functions in humans, ranging from energy restoration to memory consolidation and information integration. Sleep deprivation is linked to worsened physiological states and psychological conditions. Zebrafish are an emerging model in neurobehavioral research and have recently demonstrated great utility in the study of sleep. This teleost species possesses several of the same neurotransmitter and neuropeptide systems that are involved in the regulation of sleep and waking rhythms in higher order mammals. Previous study of these animals has revealed a differential gene and proteomic expression following sleep deprivation through changes in environmental stimuli. The present study sought to …


Grooming As An Agonistic Behavior In Garnett’S Small-Eared Bushbaby (Otolemur Garnettii), Jennie L. Christopher May 2017

Grooming As An Agonistic Behavior In Garnett’S Small-Eared Bushbaby (Otolemur Garnettii), Jennie L. Christopher

Master's Theses

Social behaviors are a necessary component of group living and interactions between organisms. To correctly assess social interactions, researchers must be able to observe behaviors and interpret their function based on the behavior or the behavioral context. In primate species, grooming is often used to assess affiliations between group members and the consensus has been to always interpret grooming as an affiliative behavior. However, a number of avian, rodent and feline species have been shown to groom conspecifics aggressively. These instances of aggressive grooming appear most often when individuals are required to maintain close proximity to one another, such as …


Seasonal And Diurnal Behavioral Patterns Of Bottlenose Dolphins, Tursiops Truncatus, That Exhibit High Site And Low Site Fidelity To Mississippi Sound, Shauna Marisa Mcbride Dec 2013

Seasonal And Diurnal Behavioral Patterns Of Bottlenose Dolphins, Tursiops Truncatus, That Exhibit High Site And Low Site Fidelity To Mississippi Sound, Shauna Marisa Mcbride

Master's Theses

This study examined whether bottlenose dolphins (Tursiops truncatus) exhibit site fidelity to the Mississippi Sound and how the seasonal and diurnal behavioral patterns of dolphins that exhibit high site fidelity to the Mississippi Sound differ from those of dolphins with lower site fidelity. Opportunistic surveys conducted from July 2006 to April 2010 were analyzed. Statistical analyses consisted of nonparametric tests (Spearman's correlation, loglinear models, and Pearson's chi-square) to compare behavioral patterns of high site fidelity, mixed, and low site fidelity groups. Behavioral patterns significantly differed between site fidelity groups across seasons and diurnal periods. Feeding behavior was observed significantly more …


An Examination Of Aggressive Behavior In Indo-Pacific Bottlenose Dolphins (Tursiops Aduncus), Lauren Elizabeth Miller May 2010

An Examination Of Aggressive Behavior In Indo-Pacific Bottlenose Dolphins (Tursiops Aduncus), Lauren Elizabeth Miller

Master's Theses

Agonistic behavior is often observed in animal groups in which individuals 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 available to the animals. In this study, video data collected from 1997 to 2007 were analyzed to examine aggressive behaviors in a wild population of Indo-Pacific bottlenose dolphins (Tursiops aduncus) off the coast ofMikura Island, Japan. The purpose of the study was to determine if age class, …


Site Fidelity And Association Patterns Of Bottlenose Dolphins (Tursiops Truncatus In The Mississippi Sound, Angela D. Mackey May 2010

Site Fidelity And Association Patterns Of Bottlenose Dolphins (Tursiops Truncatus In The Mississippi Sound, Angela D. Mackey

Master's Theses

The current study examined the site fidelity and 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 = 71) were classified as year-round residents, and 16% (n = 109) were classified as seasonal residents based on their sighting histories. Thirty-nine "select" dolphins (n = 17 seasonal residents, n = 22 yearround residents) that were sighted five or more times over the study period were used …


Variation In Social Behavior Throughout The Estrous Cycle Of A Captive Killer Whale Orcinus Orca, Kristina Marie Horback May 2010

Variation In Social Behavior Throughout The Estrous Cycle Of A Captive Killer Whale Orcinus Orca, Kristina Marie Horback

Master's Theses

The study of cetaceans in captivity provides information on behavior, acoustics, reproduction and physiology that is often difficult to obtain with free-ranging populations. The present study examined the influence of the estrous cycle of a captive female killer whale on the rate, duration, initiation and reception of social behavior she performed with her only pool mate, a male Atlantic bottlenose dolphin. Although these two delphinid species do not commonly associate in the wild, these pool mates often engaged in affiliative tactile and social behaviors. The objectives of this project were to: (a) examine the influence of cycli~ gonadal steroid hormones …
