Reproductive Plasticity In Two Subspecies Of A Cleistogamous Plant, Triodanis Perfoliata
(East Carolina University, 2015)
Dimorphic cleistogamy is an intriguing reproductive strategy in which a plant produces both closed (cleistogamous), obligately selfing flowers and open (chasmogamous) flowers. Phenotypic plasticity in the production of ...
Tadpole Begging Behavior And Parent-Offspring Interactions In The Mimic Poison Frog
(East Carolina University, 2015)
Studies on offspring begging behavior have focused on whether the behavior communicates offspring need and guides parental food provisioning in the context of honest signaling theory. However, despite the plethora of ...
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 ...
Characterization Of 'Fuzzy Tassel' Male Sterility Defects Implicates Novel MiRNA-Regulated Pathways In Maize Stamen Development
(East Carolina University, 2015)
The maize 'fuzzy tassel' ('fzt') mutant is caused by a mutation in 'dicer-like1' and has broad developmental defects. 'dicer-like1' encodes a key enzyme for microRNA (miRNA) biogenesis and many miRNAs are reduced in 'fzt' ...

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 ...
Genetic Architecture of Conspicuous Red Ornaments in Female Threespine Stickleback
(2015-12)
Explaining the presence of conspicuous female ornaments that take the form of male-typical traits has been a longstanding challenge in evolutionary biology. Such female ornaments have been proposed to evolve via both ...
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 ...
