Long-Term Impacts to the Federally Permitted For-Hire Headboat Fishery in the Gulf of Mexico Following the 2010 British Petroleum-Deepwater Horizon ("BP") Oil Disaster
(East Carolina University, 2020-06-22)To quantify possible long-term impacts from the 2010 Gulf of Mexico (GOM) Deepwater Horizon oil disaster, this study analyzed data procured from the National Oceanic and Atmospheric Administration’s mandatory Southeast ... -
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 ... -
FUNCTIONS OF G-PROTEIN COUPLED ESTROGEN RECEPTOR (GPER) IN FEMALE ZEBRAFISH REPRODUCTION
(East Carolina University, 2019-11-27)Abstract Steroid hormones such as estrogen depend on receptors like Estrogen Receptor alpha (ERα) and Estrogen Receptor (ERβ) to mediate their slow “genomic” functions, and G-Protein coupled Estrogen Receptor (GPER) to ... -
Social Factors Key to Landscape-Scale Coastal Restoration: Lessons Learned from Three U.S. Case Studies
(2020-01-23)In the United States, extensive investments have been made to restore the ecological function and services of coastal marine habitats. Despite a growing body of science supporting coastal restoration, few studies have ... -
Determining the role of the steroid hormone ecdysone in critical stages of Drosophila melanogaster early oogenesis
(East Carolina University, 2019-11-27)Reproductive function in many organisms, including Drosophila melanogaster, is controlled by steroid hormones. The main steroid hormone in Drosophila is ecdysone, which is structurally and functionally similar to estrogen. ... -
Listening to Ocean Life
(2019-05-30)By using a remotely controlled autonomous vehicle ("Blackbeard" the Acoustic Wave Glider), the authors made recordings of sounds produced by striped cusk eels, sea robins, oyster toadfish, weakfish, red drum, spotted ... -
MONITORING FISH SPAWNING LOCATIONS AND MARINE MAMMAL SOUNDS WITH PASSIVE ACOUSTIC RECORDER ON A WAVE GLIDER
(2019-07-08)Remote observations of marine animal behavior have one distinct advantage over direct observations: the observer is not present to disturb the animals. There are no vessel noises, no diver’s bubbles, no people present that ... -
Investigating Novel Chromosome 2 Genetic Variants Associated with Recurrent Stroke
(East Carolina University, 2019-07-18)As the fifth leading cause of death and leading cause of long-term disability, stroke affects 795,000 individuals annually in the United States alone. Recurrent stroke, which is far more deadly and disabling, accounts for ... -
Fine-mapping a novel locus on Chromosome 1 for associations with recurrent stroke
(East Carolina University, 2019-07-18)INTRODUCTION: Stroke is a complex, multifactorial cerebrovascular disease that afflicts millions of individuals both nationally and globally. Of the annual 795,000 stroke incidents, approximately 185,000 are recurrent ... -
NR5A family member ftz-f1 is necessary to promote oocyte development
(East Carolina University, 2019-07-15)Gamete production in mammals and insects is intimately tied to nutrition status. Conversion of nutritionally-dependent physiological signals to molecular mechanisms underlying control of oogenesis, however, remains largely ... -
A metabolomics approach to understanding recurrent stroke risk in African Americans
(East Carolina University, 2019-07-02)Stroke is a significant health burden, as the fifth leading cause of death and the number one cause of serious, long term disability in the United States. Each year 795,000 individuals suffer a stroke; of which 185,000 ... -
Cloning and Characterization of the Classical Maize Mutant, Polytypic1
(East Carolina University, 2019-07-15)Polytypic1 (Pt1) is a semi-dominant mutant in maize that affects inflorescence development. To understand how Pt1 functions in development, I examined the phenotype of Pt1 mutants in multiple inbred backgrounds. Pt1 defects ... -
EFFECTS OF SODIUM BENOZATE ON FAT DEPOSITION AND GROWTH IN CAENORHABDITIS ELEGANS
(East Carolina University, 2019-07-11)Clinical observation has proposed the linkage between the occurrence of obesity and slow weight loss with daily exposure to common food additives such as sodium benzoate. However, well-controlled laboratory experiments on ... -
NATIVE PLANT LANDSCAPING FOR POLLINATORS ON EASTERN NORTH CAROLINA SOLAR FARMS
(East Carolina University, 2019-07-15)Solar panel farms (SPFs) may be a part of a sustainable solution to pollinator decline and the loss of ecosystem services they provide. Some SPFs are seeking to landscape with diverse native seed mixes, which has the ... -
Investigating the role of transcription factor, Trl, during germline development in the Drosophila ovary
(East Carolina University, 2019-07-22)Oogenesis is the process by which an egg develops from undifferentiated cells in the ovary. The Drosophila melanogaster ovary is an assembly line for egg production, making it a great system to investigate initial oocyte ... -
Hickory Shad (Alosa mediocris) Population Identification Using Geometric Morphometrics and Otolith Shape
(East Carolina University, 2019-08-05)Hickory Shad Alosa mediocris is an anadromous species of fish belonging to the Family Clupeidae, first described in 1814 by Samuel L. Mitchill. Little is known about its life history or stock status. It is unknown whether ... -
The effects of stress on avian gene expression and microbiomes
(East Carolina University, 2019-07-24)Organisms must cope with stressors throughout their lifetime. Stressors are broad and come from both intrinsic and extrinsic sources. In this era of rapid global change, exposure to stressors will become more unpredictable ... -
ANDROGEN AND PROGESTERONE RECEPTORS KNOCKOUTS IN ZEBRAFISH AFFECT AGGRESSION AND SOCIAL DOMINANCE
(East Carolina University, 2019-05-03)ABSTRACT - There is circumstantial evidence that steroids, such as androgens and progesterone, play roles in aggression and social behaviors in vertebrates. However, the genetic basis for these behaviors needs to be further ... -
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% ...
