Historical Ecology of Striped Bass Stocking in the Southeastern United States
(East Carolina University, 2012)Striped bass (Morone saxatilis) is the most recreationally and commercially important non-salmonid fish species in the continental United States. As such, it has been exploited to the point of collapse at various points ... -
Hox Gene Expression During Oreochromis niloticus Pharyngeal Arch Development : Discovering the Hox Code
(East Carolina University, 2010)Hox genes encode transcription factors and have been extensively studied by evolutionary and developmental biologists. Hox genes are responsible for determining specific regional identities along the anterior-posterior and ... -
Hybridization in two subspecies of triodanis perfoliata, a cleistogamous annual plant (campanualaceae)
(East Carolina University, 2013)The presence of a cleistogamous (obligately selfing) plant breeding system may have implications for reproductive isolation between species. The effects of this trait on plant hybridization previously have received little ... -
Hydrogeomorphology and Horizontal Movement of Juncus roemerianus
(East Carolina University, 2015)Juncus roemerianus, black needlerush, is common in high marshes and occasionally in low marshes along the Mid-Atlantic and southern USA. Previous work found that J. roemerianus patches remained relatively stable in the ... -
Hypoxia and Serum Deprivation in Human Mesenchymal Stem Cells, and the Protective Role of Thymosin [Beta]-4
(East Carolina University, 2011)Background: Current literature suggests nutrient deprivation and hypoxia affect human mesenchymal stem cell (hMSC) survival after cell transplantation. Wound-healing protein Thymosin [beta]-4 (T[beta]-4) has been shown ... -
Identification and mapping of two divergent, unlinked major histocompatibility complex class II B genes in Xiphophorus fishes.
(East Carolina University, 1998-08)We have isolated two major histocompatibility complex (MHC) class II B genes from the inbred fish strain Xiphophorus maculatus Jp 163 A. We mapped one of these genes, designated here as DXB, to linkage group III, linked ... -
IDENTIFICATION OF GEOCHEMICAL TRACERS WITHIN BIOMINERALS OF JUVENILE AND LARVAL MERCENARIA MERCENARIA : IMPLICATIONS FOR MODELING LARVAL DISPERSAL
(East Carolina University, 2013)This study was designed to investigate the application of geochemical signals within biominerals to identify site fidelity and natal origin of the commercially valuable bivalve Mercenaria mercenaria. My first study ... -
Identification, Characterization, and Abiotic Stress Analysis of microRNAs in Nicotiana tabacum
(East Carolina University, 2010)microRNAs (miRNAs) are non-coding RNAs with short sequences that negatively regulate gene expression at the post-transcriptional levels by either binding to mRNAs for degradation, or by inhibiting protein translation. ... -
Identification, classification, and partial characterization of genes in humans and other vertebrates homologous to a fish membrane progestin receptor
(East Carolina University, 2003-03-04)Recently we discovered a previously uncharacterized gene with the characteristics of a membrane progestin receptor (mPR) in a fish model, spotted seatrout. Here, we report the identification, cloning, and characteristics ... -
Inbreeding Depression and Mixed Mating in Leptosiphon jepsonii: A Comparison of Three Populations
(East Carolina University, 2006-08)Background and Aims: Inbreeding depression is thought to play a central role in the evolution and maintenance of cross-fertilization. Theory indicates that inbreeding depression can be purged with self-fertilization, ... -
INSIGHTS INTO THE HABITAT AND BREEDING BIOLOGY OF THE FEDERALLY ENDANGERED HERBACEOUS PLANT, THALICTRUM COOLEYI, AHLES
(East Carolina University, 2015)Thalictrum cooleyi Ahles (Cooley's meadowrue, Ranunculaceae) is a dioecious species, endemic to fire-dependent, wet pine savannas of the southeastern US. T. cooleyi was listed as federally endangered in 1989; knowledge ... -
Interaction and Functional Analysis of Drosophila Mcm10
(East Carolina University, 2010)In eukaryotic cells, DNA replication and the subsequent packaging of DNA into specific chromatin states are essential processes for the transmission of genetic material and genomic stability which may be linked by interactions ... -
Intron position in RNA polymerase genes and their relationship to eukaryotic phylogenies
(East Carolina University, 2010)Over the past two decades, there has been an increasing amount of research devoted to the study of intron evolution and its relationship to eukaryotic phylogeny. Previous studies have shown that a large percentage of ... -
IS PREDATION BY TURTLES SUFFICIENTLY STRONG TO AFFECT BIODIVERSITY WITHIN FISHLESS PONDS?
(East Carolina University, 2011)Ecologists have long known that predation can have a strong effect on the diversity and abundance of prey in ecological communities. Much evidence on the importance of predation in aquatic systems has stemmed from studies ... -
Lateral Gene Transfer between Bacteria and Trichoderma reesei
(East Carolina University, 2012)Lateral gene transfer (LGT) has played an important role in shaping the `tree of life'. It has promoted evolution by generating gene redundancies, which allow for more freedom in terms of allowed mutations in a genome, ... -
Life History Aspects of the Hickory Shad (Alosa Mediocris) in the Albemarle Sound/ Roanoke River Watershed, North Carolina
(East Carolina University, 1998-01)The hickory shad (Alosa mediocris), which supports commercial and recreational fisheries in the Roanoke River and Albemarle Sound, North Carolina, is an anadromous species closely related to the American shad (A. sapidissima). ... -
Local and Regional Aspects of Habitat Quality Jointly Affect the Biodiversity of Ephemeral Ponds
(East Carolina University, 2012)The biodiversity of local communities is likely affected by both local habitat quality and by the quality of the landscape surrounding the locality. In pond environments, habitat quality may be affected by the kind of leaf ... -
LOCALIZATION AND CHANGES OF NUCLEAR PROGESTERONE RECEPTORS IN ZEBRAFISH OOCYTES AND ADJACENT FOLLICULAR CELLS
(East Carolina University, 2010)The nuclear progesterone receptor (Pgr) is one of the major mediators for progestin signaling during oocyte ovulation in vertebrates. However, any roles Pgr may play in oocyte growth, and especially in the final oocyte ... -
Maturation, Fecundity, and Spawning Frequency of the Albemarle/Roanoke Striped Bass Stock
