Habitat Use By Bottlenose Dolphins, Tursiops Truncatus, In Roanoke Sound, North Carolina, Shauna Marisa Mcbride Dec 2016

Habitat Use By Bottlenose Dolphins, Tursiops Truncatus, In Roanoke Sound, North Carolina, Shauna Marisa Mcbride

Dissertations

Information on the habitat use of a species is important to develop conservation efforts and management strategies for that species. Roanoke Sound, North Carolina is primarily a seasonal habitat for bottlenose dolphins, Tursiops truncatus, from late spring to early fall, but little information is known about how dolphins use this area. Transect survey data and opportunistic survey data collected by the Outer Banks Center for Dolphin Research from 2009 to 2015 were used to analyze dolphin habitat use. The objectives of this project were to: 1) identify areas that were important to dolphins, 2) determine which behaviors were observed …


Status Signaling And The Characterization Of A Chirp-Like Signal In The Weakly Electric Fish Steatogenys Elegans, Caitlin E. Field Feb 2016

Status Signaling And The Characterization Of A Chirp-Like Signal In The Weakly Electric Fish Steatogenys Elegans, Caitlin E. Field

Dissertations, Theses, and Capstone Projects

Sensory systems are critical to both exploratory and communicatory processes, the study of which is critical to our understanding of how animals perceive and respond to their environments. In weakly electric fishes the electrosensory system is utilized for both of these purposes. One type of communication, status signaling, is widespread across taxa and frequently hormonally modulated. This hormonal modulation keeps the signal honest, wherein the status of the sender and the production of the status signal itself are both hormone dependent. We investigated exploratory and communicatory strategies of the electromotor system in pulse-type gymnotiforms, with a focus on status communication …
