Neurological Effects Of A Single Low Level Blast Overpressure Exposure : Behavior And Micro RNA Mechanisms Of Mild Traumatic Brain Injury In A Rodent Model
(East Carolina University, 2015)
The increased use of explosive devices within warfare and acts of terrorism has allowed blast overpressure exposure (BOE) to become a significant concern. The most common wound sustained by BOE is blast-induced mild traumatic ...
Incorporating Migration and Local Movement Patterns into Management Strategies for Spiny Dogfish (Squalus acanthias)
(East Carolina University, 2015-12-15)
The overall purpose of this dissertation is to increase understanding of migration and movement behaviors associated with a highly migratory elasmobranch species. In particular, I seek to determine whether sufficient ...
Nicotine Controlof Germline Cell Fate in Caenorhabditis elegans
(2015-05)
Nicotine dependence is the single largest cause of preventable death in the world, claiming 480,000 lives each year in the US alone, including those caused by secondhand smoke. In this study, we investigated the biological ...
THE EFFECTS OF PRENATAL LEAD EXPOSURE ON THE DEVELOPMENT OF BIOMARKERS OF ALZHEIMER’S DISEASE
(2015-04)
While often well known for its adverse effects on memory, Alzheimer’s disease (AD) is also noteworthy for being the sixth leading cause of death in the United States. An estimated 5.2 million Americans had the disease as ...
Conspicuous Female Ornamentation and Tests of Male Mate Preference in Threespine Sticklebacks (Gasterosteus aculeatus)
(2015-03-25)
Sexual selection drives the evolution of exaggerated male ornaments in many animal species. Female ornamentation is now acknowledged also to be common but is generally less well understood. One example is the recently ...
Exposure To Elevated Prenatal Testosterone Metabolites Induce Autism-Like Behavior In Rats : Evidence For The Extreme Male Brain And Implications For Human Health
(East Carolina University, 2015)
Neurodevelopmental disorders such as autism spectrum disorder (ASD) originate during early brain development and are the result of complex interactions between genetic and environmental factors. Disruptions in the prenatal ...
Gene Expression Divergence Between Zebra Finch (Taeniopygia Guttata) Subspecies And Gene Regulation In Hybrids
(East Carolina University, 2015)
Since the publication of Mayr's Systematics and the Origin of Species, birds have been important model organisms for studies regarding evolutionary processes such as sexual selection and speciation. In this study, I will ...
Species And Stage Specific Developmental Toxicity Of Endosulfan Exposure In Hyla Cinerea And Ranitomeya Imitator
(East Carolina University, 2015)
During ontogeny, organisms pass through critical periods of heightened vulnerability to disruptive exogenous agents. In organisms with complex life cycles, these developmental windows result in variable susceptibility ...
A practical guide and power analysis for GLMMs: detecting among treatment variation in random effects
(2015-09)
In ecology and evolution generalized linear mixed models (GLMMs) are becoming increasingly used to test for differences in variation by treatment at multiple hierarchical levels. Yet, the specific sampling schemes that ...
Lack of K-Dependent Oxidative Stress in Cotton Roots Following Coronatine-Induced ROS Accumulation
(2015-05)
Coronatine [COR] is a novel type of plant growth regulator with similarities in structure and property to jasmonate. The objective of this study was to examine the relationship between increased root vitality induced by ...
