Gene Expression and the Evolution of Reduced Sexual Dimorphism in a Threespine Stickleback Color Trait
(East Carolina University, 2017-01-03)
Elucidating the processes and mechanisms responsible for sexual dimorphism has been a central task for evolutionary biologists since Darwin first proposed the concept of sexual selection. However, our understanding of the ...
Impact of Vessel Noise on Oyster Toadfish (Opsanus tau) Behavior and Implications for Underwater Noise Management
(East Carolina University, 2017-05-03)
Underwater noise and its impacts on marine life are growing management concerns. This dissertation considers both the ecological and social concerns of underwater noise, using the oyster toadfish (Opsanus tau) as a model ...
The effects of elevated temperature and dissolved ρCO2 on a marine foundation species
(2017-04)
Understanding how climate change and other environmental stressors will affect species is a fundamental concern of modern ecology. Indeed, numerous studies have documented how climate stressors affect species distributions ...
Sexual Dimorphism and Trophic Trait Evolution in the Carolina Bay Fundulus Complex
(East Carolina University, 2017-01-05)
Convergent evolution in similar environments is widely held to provide some of the strongest evidence for natural selection's role in evolution, and convergent or parallel evolution of reproductive isolation, best studied ...
The Effect of Visual Queues on Social Status Formation and Mauthner Sensitivity in Zebrafish
(East Carolina University, 2017-04-27)
Zebrafish of the TLN strain, a genetic variant of the Tüpfel Long-fin (TL) wild-type zebrafish that does not display the trademark striped scale pattern of wild-type zebrafish, but are instead pale, were tested through a ...
Characterizing Interactions of Thioflavin-T with Native Proteins Especially Bovine Serum Albumin
(East Carolina University, 2017-05-03)
Thioflavin T is a fluorescent probe used to monitor formation of cross [beta]-sheet rich amyloid fibrils. Involvement of the amyloid fibrils is implicated in more than 50 human diseases, such as Alzheimer's, Parkinson's ...
Wetland management strategies lead to tradeoffs in ecological structure and function
(2017-12)
Anthropogenic legacy effects often occur as a consequence of land use change or land management and can leave behind long-lasting changes to ecosystem structure and function. This legacy is described as a memory in the ...
INVESTIGATING THE EFFECTS OF LARVAL PHENOTYPES ON TRAITS EXHIBITED AT A CRUCIAL LIFE-HISTORY SWITCH POINT
(East Carolina University, 2017-07-25)
In organisms with complex life histories, phenotypes exhibited in non-reproductive life stages are often correlated with adult performance and fitness. For example, in anurans (frogs and toads), age and size at metamorphosis ...
The Direct and Indirect Impact of Sucralose on Immune Function
(East Carolina University, 2017-12-18)
1, 6-dichloro-1, 6- dideoxy-[beta]-D-fructofuranosyl-4-chloro-4-deoxy -[alpha]-D-galactopyranoside, or Sucralose, is a highly popular NAS (Non-caloric artificial sweetener) used by millions across the globe for sweetening ...
Behavioral and genetic divergence among wild and domesticated populations of the zebra finch (Taeniopygia guttata)
(East Carolina University, 2017-07-18)
Zebra finches (Taeniopygia guttata) have been the subject of extensive neurological and behavioral research having served as the dominant model for vocal learning over half a century. Learned vocal communication, or vocal ...
