An assessment of the polytypic status of the Namib darkling beetles Onymacris unguicularis and Onymacris rugatipennis
(2014-12-10)
The southern African beetle genus Onymacris (family Tenebrionidae) comprises 14 species, six of which are polytypic. Despite longstanding research on the physiological and behavioral adaptations of these desert beetles, ...
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 ...
Conspicuous Female Ornamentation and Tests of Male Mate Preference in Threespine Sticklebacks (Gasterosteus aculeatus)
(2015-03-25)
Sexual selection drives the evolution of exaggerated male ornaments in many animal species. Female ornamentation is now acknowledged also to be common but is generally less well understood. One example is the recently ...
Fish assemblage and habitat use in North Carolina and Virginia waters during the annual Cooperative Winter Tagging Cruise, 1988-2013
(East Carolina University, 2018-12-10)
Long-term ecological research can be valuable in understanding ecosystem function and species requirements, allowing managers to better regulate and enforce strategies for continued use of the resource, commercially and ...
ARE ALL FISH NURSERIES EQUAL? DETERMINING HOW FOOD WEB DYNAMICS AFFECT FISH NURSERY HABITAT
(East Carolina University, 2018-07-23)
The fish nursery habitat concept has been used to define important habitat for larval and juvenile fish throughout coastal and estuarine areas. Nursery habitat has been defined as an area that produces more fish biomass, ...
Control of maize development by microRNA and auxin regulated pathways
(East Carolina University, 2018-12-10)
Plant architecture and inflorescence architecture, in particular, are major determinates of yield. Plant architecture is dependent upon the activity of meristems. Meristems are vital to plant development because they not ...
What Factors Maintain the Mixed Mating System of a Local Annual Plant, Triodanis perfoliata?
(East Carolina University, 2019-05-02)
A plant capable of reproducing by cross- and self-fertilization is known to have a mixed mating system. This system is an evolutionary puzzle to many researchers because the factors maintaining both outcrossing and selfing ...
SYSTEMATIC BENZOATE PRESERVATIVE ANALYSIS IN POPULAR BEVERAGES
(East Carolina University, 2019-05-02)
Introduction
Benzoic acid derivatives (such as sodium benzoate and potassium benzoate) are frequently added to commercial beverages as a preservative. FDA regulations prohibit benzoate levels from exceeding 1000 mg/L (0.1% ...
The Generation of an Antibody to the Bearded-Ear Protein in Maize
(East Carolina University, 2019-05-02)
Flowers are essential for plants to reproduce and also produce seeds and fruits that are consumed as food. Zea mays (maize) is both a staple crop and serves as a model for other grass species. In maize, male and female ...
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 ...
