Comparison of a Traditional Teaching Model to the SCALE-UP Teaching Model in Undergraduate Biology: A Mixed Method Study
(East Carolina University, 1/13/16)
This project compared a SCALE-UP teaching model to a traditional teaching model. Traditional teaching is now considered a poor motivator for student performance and interests, and the SCALE-UP model was proposed to combat ...
Assessing The Monophyly Of Red Algae And Green Plants Via Core Conserved Informational Genes
(East Carolina University, 2015)
For well over a century the existence of a monophyletic relationship between red algae and green plants has been debated. Many scholars have sought to address this issue, however, a consistent solution to the problem has ...
Rectifying Limitations On Species Delineation In Dusky Salamanders : Lineage Detection Using An Ecoregion-Drainage Sampling Regime
(East Carolina University, 2015)
The dusky salamanders (Desmognathus) constitute a large, species-rich group, and although a considerable body of literature exists on systematic relationships and adaptive trends, these issues have heretofore been approached ...
Metabolic, Physiological, And Behavioral Responses Of Prey To Predation
(East Carolina University, 2015)
Predators are known to cause prey to alter their morphology, life history or behavior in ways that reduce the likelihood of the prey being consumed by the predator. Seldom considered, however, are the consequences of ...
Possible Effects Of Climate Change On Induced Defenses In Tadpoles
(East Carolina University, 2015)
Global climates are changing and the rate of change is expected to increase in the next century. Researchers predict that temporary ponds will be affected, resulting in shorter average hydroperiods (the amount of time a ...
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 ...
An investigation of alkaloid sequestration by the poison frog Dendrobates auratus when fed the fire ant Solenopsis invicta
(East Carolina University, 1/13/16)
Poison frogs are known for their bright coloration, parental care, and defensive toxins. Over 850 different alkaloids have been discovered in the skin of poison frogs. The alkaloid defenses are acquired from a specialized ...
SPATIAL EXPRESSION OF MATRIX AND MATRIX RECEPTOR PROTEINS IN THE DEVELOPING SYNOVIAL JOINT
(East Carolina University, 2013)
Little is understood about the complex spatial and temporal molecular interactions necessary to form a fully functional synovial joint. Understanding molecular pathways and signaling within the developing joint continues ...
Responses of Leaf Litter Breakdown Rates and Microbial Enzyme Activity to Salinity in North Carolina Wetlands
(East Carolina University, 2014)
Sea-level rise and human activities are causing the increase of salinity in coastal freshwater wetlands. Increased salinity in some wetlands has been found to accelerate leaf litter decomposition, an important driver of ...
USING LASER CAPTURE MICRODISSECTION (LCM) TO EXAMINE MADS-BOX GENE EXPRESSION IN THE UPPER AND LOWER FLORAL MERISTEMS OF MAIZE
(East Carolina University, 2013)
MADS-box transcription factors are important regulators of flower development in all flowering plants. In the grasses, flowers (called florets) are contained in spikelets. Maize spikelets contain two florets (the upper and ...
