RDX Induces Aberrant Expression of MicroRNAs in Mouse Brain and Liver
(East Carolina University, 2009-02)Background: Although microRNAs (miRNAs) have been found to play an important role in many biological and metabolic processes, their functions in animal response to environmental toxicant exposure are largely unknown. ... -
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 ... -
REDUCING ENVIORNMENTALLY INDUCED BIRTH DEFECTS WITH PRENATAL SUPPLEMENTION
(East Carolina University, 2019-05-02)Pollutant exposure during development has been shown to induce developmental malformations. For example, penis deformities are the most common birth defects occurring in boys born in the United States, and are associated ... -
Repair of Clustered DNA Lesions in Double Strand Break Repair Deficient Human Tumor Cells
(East Carolina University, 2010)DNA-dependent protein kinase (DNA-PK) is a holoenzyme of three subunits, Ku70, Ku80, and the DNA-Pk catalytic subunit (DNA-PKcs). DNA-PK serves a role in non-homologous end joining to repair double stranded breaks, and ... -
REPRODUCTIVE ISOLATION AND MIMETIC DIVERGENCE IN THE POISON FROG RANITOMEYA IMITATOR
(East Carolina University, 2014)Understanding the process of speciation requires examination of various stages of its progress. This work focuses on the early stages of population divergence, where populations of a single species may show varying levels ... -
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 ... -
Reproductive Toxicity of Diazinon on Caenorhabditis elegans
(East Carolina University, 2017-07-17)Worldwide, pesticide usage is on the rise. From 2006-2007, the global market saw a 1% increase in overall pesticide usage (Environmental Protection Agency 2012), a small percentage until you consider that one percent ... -
RESPONSE OF A SPARTINA PATENS-DOMINATED OLIGOHALINE MARSH TO NITROGEN ENRICHMENT IN COASTAL NORTH CAROLINA, USA.
(East Carolina University, 2013)Coastal marshes are highly productive ecosystems that play a significant role in the global carbon budget. Anthropogenic alterations to coastal landscapes can significantly impact these marsh ecosystems, though the actual ... -
Response of Baldcypress (Taxodium distichum) at Different Life Stages to Flooding and Salinity
(East Carolina University, 2014)Baldcypress are dominant trees in forested coastal wetlands. As sea levels rise, it is important to increase our understanding of how increased salinity and flooding will affect forested coastal wetlands. This study combined ... -
RESPONSES OF COASTAL NESTING KING RAILS (RALLUS ELEGANS) TO ENVIRONMENTAL THREATS OF RISING WATER AND TEMPERATURE
(East Carolina University, 2015-12-09)King rail (Rallus elegans) populations are experiencing long-term declines attributable to habitat loss. Sparse breeding populations in coastal areas may represent the last strongholds for this species, but climate change ... -
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 ... -
REWETTING POCOSIN WETLANDS LOWERS GREENHOUSE GAS EMISSIONS
(East Carolina University, 2017-12-12)Restored peatlands are known to be highly efficient carbon sinks and wetland restoration efforts take advantage of this efficiency to use as a climate change mitigation strategy. Evaluating the carbon sequestration capacity ... -
Risk Assessment and Behavioral Choices of Larval Anurans (Lithobates Sphenocephalus)
(2011-04)Larval anurans assess risk and make behavioral choices to avoid predation. Since antipredator behaviors may reduce foraging opportunities, prey behavioral decisions can be constrained by a tradeoff between survival and ... -
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 ... -
RIVER HERRING ENVIRONMENTAL DNA: ESTIMATING RATES OF SHEDDING, DECAY, AND TRENDS IN THE ENVIRONMENT
River herring, (Blueback Herring [Alosa aestivalis] and Alewife [A. pseudoharengus]), were once abundant in North Carolina waters and were an economically important fishery but their populations across their ranges are ...
