Reproductive Plasticity In Two Subspecies Of A Cleistogamous Plant, Triodanis Perfoliata
Colbert, Lauren I. (East Carolina University, 2015)Dimorphic cleistogamy is an intriguing reproductive strategy in which a plant produces both closed (cleistogamous), obligately selfing flowers and open (chasmogamous) flowers. Phenotypic plasticity in the production of ... -
Reproductive Toxicity of Crude oil-Dispersant Mixture in Caenorhabditis elegans
Zhang, Yanqiong (East Carolina University, 2016-05-05)As crude oil remains a vital natural resource for the energy need of the world, environmental crude oil spills continue to be a health risk to human beings and ecological systems. During clean-up efforts, surfactant-like ... -
Reproductive Toxicity of Diazinon on Caenorhabditis elegans
Cobb, Juliana (East Carolina University, 2017-07-17)Worldwide, pesticide usage is on the rise. From 2006-2007, the global market saw a 1% increase in overall pesticide usage (Environmental Protection Agency 2012), a small percentage until you consider that one percent ... -

RESPONSE OF A SPARTINA PATENS-DOMINATED OLIGOHALINE MARSH TO NITROGEN ENRICHMENT IN COASTAL NORTH CAROLINA, USA.
Wejrowski, Mark (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
Powell, Amanda S. (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 ... -
RESPONSES OF COASTAL NESTING KING RAILS (RALLUS ELEGANS) TO ENVIRONMENTAL THREATS OF RISING WATER AND TEMPERATURE
Clauser, Amanda J. (East Carolina University, 2015-12-09)King rail (Rallus elegans) populations are experiencing long-term declines attributable to habitat loss. Sparse breeding populations in coastal areas may represent the last strongholds for this species, but climate change ... -
Responses of Leaf Litter Breakdown Rates and Microbial Enzyme Activity to Salinity in North Carolina Wetlands
Korn, Patrick R. (East Carolina University, 2014)Sea-level rise and human activities are causing the increase of salinity in coastal freshwater wetlands. Increased salinity in some wetlands has been found to accelerate leaf litter decomposition, an important driver of ... -

RETINOIC ACID REGULATES KIT PROTEIN EXPRESSION IN PERITUBULAR MYOID CELLS IN THE MAMMALIAN TESTIS
Malachowski, Taylor N (East Carolina University, 2021-05-28)Spermatogenesis (production of sperm) takes place in the testis, which is composed of seminiferous tubules. Within mammalian seminiferous tubules, there are two cell types: germ cells and supporting somatic cells. The ... -
REWETTING POCOSIN WETLANDS LOWERS GREENHOUSE GAS EMISSIONS
Armstrong, Luise (East Carolina University, 2017-12-12)Restored peatlands are known to be highly efficient carbon sinks and wetland restoration efforts take advantage of this efficiency to use as a climate change mitigation strategy. Evaluating the carbon sequestration capacity ... -
Risk Assessment and Behavioral Choices of Larval Anurans (Lithobates Sphenocephalus)
Albecker, Molly (2011-04)Larval anurans assess risk and make behavioral choices to avoid predation. Since antipredator behaviors may reduce foraging opportunities, prey behavioral decisions can be constrained by a tradeoff between survival and ... -
River Herring Nursery Habitat in Albemarle Sound, North Carolina, Inferred from Otolith Microchemistry
Zapf, Daniel Hunter (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 ... -
RNA polymerase II CTD Evolutionary Diversity and Associated Protein Identification in Green and Red Algae
Yang, Chunlin (East Carolina University, 2014)In model eukaryotes, the C-terminal domain (CTD) of the largest subunit (RPB1) of DNA-dependent RNA polymerase II is composed of tandemly repeated heptads with the consensus sequence YSPTSPS. Both the core motif and tandem ... -
The Role of GSK-3[beta] in MCF-7 Breast Cancer Cell Signaling and Drug Resistance
Sokolosky, Melissa Lynn (East Carolina University, 2011)Glycogen synthase kinase- 3beta (GSK-3beta) is well documented to participate in a complex array of critical cellular processes. This versatile protein is involved in numerous signaling pathways that influence metabolism, ...
