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 ...
Risk assessment based on indirect predation cues: revisiting fine-grained variation
(2015-10)
To adaptively express inducible defenses, prey must gauge risk based on indirect cues of predation. However, the information contained in indirect cues that enable prey to fine-tune their phenotypes to variation in risk ...
A depauperate immune repertoire precedes evolution of sociality in bees
(2015-04-24)
Background
Sociality has many rewards, but can also be dangerous, as high population density and low genetic diversity, common in social insects, is ideal for parasite transmission. Despite this risk, honeybees and other ...
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 ...
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 ...
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 ...
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 ...
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 ...
Stable Recombination Hotspots in Birds
