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 …
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 …
Impacts Of Oil Exposure During Early Life Development Stages In Sheepshead Minnows (Cyprinodon Variegatus) Under Different Environmental Factors, Danielle Simning
Impacts Of Oil Exposure During Early Life Development Stages In Sheepshead Minnows (Cyprinodon Variegatus) Under Different Environmental Factors, Danielle Simning
Master's Theses
The release of approximately 5 million barrels of crude oil into the northern Gulf of Mexico during the 2010 Deepwater Horizon oil spill jeopardized estuarine ecosystem health from Texas to Florida. These estuarine habitats, which serve as nurseries for many important fisheries are also prone to rapid fluctuations in environmental stressors such as oxygen concentration, and salinity. The consequence of combined exposure to crude oil and suboptimal environmental factors during early life stage development of fish is still largely unknown. The objective of this project was to investigate the impacts of exposure to crude oil in combination with varying environmental …
Defining Success: The Perspective Of Emerging Adults With Foster Care Experience, Brianna Lynne Anderson
Defining Success: The Perspective Of Emerging Adults With Foster Care Experience, Brianna Lynne Anderson
Master's Theses
Youth with experience in the foster system are often more susceptible to negative outcomes in adulthood due to their high levels of cumulative risk. The present study sought out to re-define the concept of “success” from the perspective of emerging adults with experience in the foster care system and to identify patterns among the characteristics and behaviors of foster families that promote success as these young adults transition out of the foster care system and into adulthood. Participants most frequently defined “success” as achieving personal goals. Additionally, Support and Positive Identity were found to be the most influential Developmental Assets® …
The Ontogeny Of Whistle Production In Infant Atlantic Bottlenose Dolphins (Tursiops Truncatus) During The First Thirty Days Of Life, Brittany Leigh Jones
The Ontogeny Of Whistle Production In Infant Atlantic Bottlenose Dolphins (Tursiops Truncatus) During The First Thirty Days Of Life, Brittany Leigh Jones
Master's Theses
The manner in which dolphin calves acquire their whistle repertoire is largely unknown. This paper focuses on whistle development in four bottlenose dolphin calves during the first thirty days of life in order to increase our understanding of the early emergence of whistles and whistle-like vocalizations. The acoustic parameters of whistle-type vocalizations (i.e., whistles and whistlesquawks) that coincided with a bubblestream emission from the focal calf and/or its mother were analyzed, as were the behavioral states of the mother-calf pair during the emission of such vocals. Mother and calf whistle rates are inversely related, with the mother whistling more often …
