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% ... -
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 ... -
Molecular chaperone Tetratricopeptide repeat protein 2 (Tpr2) is essential for germline stem cell self-renewal and timely cyst divisions in Drosophila melanogaster oogenesis
(East Carolina University, 2019-05-02)Steroid hormones influence cell proliferation and cell fate in developing and injured tissues. Although steroid hormone signaling has been well-studied, the precise mechanisms by which cells specifically receive steroid ... -
BEHAVIORAL STUDY OF GOBIOSOMA BOSC IN RESPONSE TO VISUAL IMPLANT ELASTOMER (VIE) TAGGING
(East Carolina University, 2019-05-02)The naked goby (Gobiosoma bosc) is a small benthic fish that inhabits western Atlantic estuaries, where it ranges from Massachusetts to Mexico. Previous work has found limited gene flow between and among populations of G. ... -
The Role of the Melanocortin-1 Receptor Gene in Müllerian Mimic Ranitomeya imitator
(East Carolina University, 2019-05-02)The Peruvian poison dart frog Ranitomeya imitator has undergone a Müllerian mimetic radiation, which means that this species has evolved color patterns that mimic three other poison dart frogs in different geographic regions ... -
Consequences Of Long-Term Fertilization on Wetland Microbial Function
(East Carolina University, 2019-05-02)Anthropogenic disturbances have led to increased deposition of nitrogen (N) and phosphorus (P) into soils. Nutrient enrichment of soils is known to increase plant biomass and also increase rates of microbial litter ...
