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 ... -
