Natal Origin of Central Southern Management Area, North Carolina Striped Bass, Inferred from Otolith Microchemistry
(East Carolina University, 2013)Striped bass (Morone saxatilis) is an important commercial and game fish throughout North Carolina coastal waters. These fish have spawning populations present in all of the state's coastal rivers, however populations south ... -
PARSING POLYPHYLETIC PUERARIA : DELIMITING DISTINCT EVOLUTIONARY LINEAGES THROUGH PHYLOGENY
(East Carolina University, 2013)A taxon is defined as polyphyletic when it does not include the last common ancestor of all true members of the taxon, resulting in a number of subgroups not united by a common ancestor. Previous work has suggested Pueraria ... -
Patterns of Succession in Man-Made and Natural Wetlands
(East Carolina University, 1990-03)The response of estuarine benthos to disturbance was investigated to test the hypotheses that season, sediment, composition, and location significantly affect patterns of recolonization. The study was conducted in two ... -
Phylogenetics and Systematics of the Millipede genus Brachycybe Wood, 1864 (Platydesmida: Andrognathidae)
(East Carolina University, 2010)The genus Brachycybe Wood, 1864 (Platydesmida: Andrognathidae) belongs to an ancient millipede lineage that has persisted since the Miocene. The group displays a Holarctic distribution with species in the eastern Nearctic, ... -
Physiological and Phylogenetic Studies of the Biogeography of Alkaliphilic Heterotrophic Bacteria from Serpentinizing Habitats
(East Carolina University, 2014)Serpentinization occurs when ultramafic rocks containing the mineral olivine react with water to produce highly reducing conditions, which are commonly coincident with high concentrations of hydrogen. Hydrogen provides ... -
Physiological Studies of Alkaliphilic Anaerobic Organotrophs in a Serpentinizing Subsurface Habitat
(East Carolina University, 2014)Microbial habitats in serpentinizing ultramafic rocks represent one of the largest, yet least understood portions of the biosphere, with potentially major consequences for global biogeochemical cycles. Serpentinization is ... -
Pleistocene glacial refugia across the Appalachian Mountains and coastal plain in the millipede genus Narceus: Evidence from population genetic, phylogeographic, and paleoclimatic data
(East Carolina University, 2009-01-30)Background: Species that are widespread throughout historically glaciated and currently nonglaciated areas provide excellent opportunities to investigate the role of Pleistocene climatic change on the distribution of North ... -
Posttranslational modifications in the CP43 subunit of photosystem II
(East Carolina University, 2002-11-12)Photosystem II (PSII) catalyzes the light-driven oxidation of water and the reduction of plastoquinone; the oxidation of water occurs at a cluster of four manganese. The PSII CP43 subunit functions in light ... -
Predator Out of Place : The Differential Impacts of Native and Non-native Crayfish on Bufo Tadpoles
(East Carolina University, 2010)Predators have been shown to alter important fitness components (larval period, mass at metamorphosis, and overall survivorship) of larval anurans. Uncommonly studied predators of tadpoles include crayfish. Both native and ... -
Priority effects of overwintered Rana tadpoles on larval Southern toad (Bufo terrestris Bonnaterre)
(East Carolina University, 2010)In natural ecosystems, the order of species arrival can impact the development of the community. In the Atlantic Coastal Plain of the Carolinas, wetland ponds exhibit a wide range of hydroperiods, ranging from ponds that ... -
Processing of bistranded abasic DNA clusters in γ-irradiated human hematopoietic cells
(East Carolina University, 2004)Clustered DNA damages—two or more lesions on opposing strands and within one or two helical turns—are formed in cells by ionizing radiation or radiomimetic antitumordrugs. They are hypothesized to be difficult to repair, ... -
PROLACTIN FUNCTION IN ZEBRAFISH DEVELOPMENT
(East Carolina University, 2010)Extensive studies have implicated a myriad of functional roles for prolactin (PRL) and prolactin receptor (PRLR) across a variety of adult vertebrate species. However, much less is known about the physiological role(s) of ... -
Proserpinaca: Photoperiodic and Chemical Differentiation of Leaf Development and Flowering
(East Carolina University, 1967-05)Proserpiniaca palustris L. produced juvenile leaves on 8-hour photoperiods, adult leaves on 12-hour photoperiods, and adult leaves and flowers on 14-hotur photoperiods. Treatment of pliants growing on 8- and 14-houir ... -
Psf2, a member of the heterotetrameric GINS Complex, plays a role in cell cycle progression and maintenance of genomic integrity
(East Carolina University, 2010)Multiple proteins are involved in the complete and accurate replication of the genome during S phase of the cell cycle. At the G1/S phase transition, the heterotetrameric GINS complex is recruited to the origin, and ... -
RDX and miRNA Expression: Zhang and Pan Respond

RDX Induces Aberrant Expression of MicroRNAs in Mouse Brain and Liver
(East Carolina University, 2009-02)Background: Although microRNAs (miRNAs) have been found to play an important role in many biological and metabolic processes, their functions in animal response to environmental toxicant exposure are largely unknown. ... -
RESPONSE OF A SPARTINA PATENS-DOMINATED OLIGOHALINE MARSH TO NITROGEN ENRICHMENT IN COASTAL NORTH CAROLINA, USA.
(East Carolina University, 2013)Coastal marshes are highly productive ecosystems that play a significant role in the global carbon budget. Anthropogenic alterations to coastal landscapes can significantly impact these marsh ecosystems, though the actual ... -
Response of Baldcypress (Taxodium distichum) at Different Life Stages to Flooding and Salinity
(East Carolina University, 2014)Baldcypress are dominant trees in forested coastal wetlands. As sea levels rise, it is important to increase our understanding of how increased salinity and flooding will affect forested coastal wetlands. This study combined ... -
River Herring Nursery Habitat in Albemarle Sound, North Carolina, Inferred from Otolith Microchemistry
(East Carolina University, 2012)River herring is a collective term used to describe two similar alosine species: alewife Alosa pseudoharengus and blueback herring A. aestivalis. Both of these anadromous species are native to the Atlantic coast of North ... -
Roanoke River Water Flow Committee Report for 1988 and 1989
(East Carolina University, 1990-04)A committee of 20 representatives of State and Federal agencies and university scientists was formed in 1988 to gather information on all resources of the lower Roanoke River watershed in North Carolina and to recommend ...
