Non-Linear Interactions between Consumers and Flow Determine the Probability of Plant Community Dominance on Maine Rocky Shores
(2013)Although consumers can strongly influence community recovery from disturbance, few studies have explored the effects of consumer identity and density and how they may vary across abiotic gradients. On rocky shores in Maine, ... -
Nonconsumptive effects in a multiple predator system reduce the foraging efficiency of a keystone predator
(2013-09)Many studies have demonstrated that the nonconsumptive effect (NCE) of predators on prey traits can alter prey demographics in ways that are just as strong as the consumptive effect (CE) of predators. Less well studied, ... -
De Novo Transcriptome Assembly and Comparative Analysis Elucidate Complicated Mechanism Regulating Astragalus chrysochlorus Response to Selenium Stimuli
(2015-10)Astragalus species are medicinal plants that are used in the world for years. Some Astragalus species are known for selenium accumulation and tolerance and one of them is Astragalus chrysochlorus, a secondary selenium ... -
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 ... -
Nuclear Progesterone Receptors Are Up-Regulated by Estrogens in Neurons and Radial Glial Progenitors in the Brain of Zebrafish
(2011)Abstract In rodents, there is increasing evidence that nuclear progesterone receptors are transiently expressed in many regions of the developing brain, notably outside the hypothalamus. This suggests that progesterone ... -
Nuclear Progestin Receptor (Pgr) Knockouts in Zebrafish Demonstrate Role for Pgr in Ovulation but Not in Rapid Non-Genomic Steroid Mediated Meiosis Resumption
(2015-03)Progestins, progesterone derivatives, are the most critical signaling steroid for initiating final oocyte maturation (FOM) and ovulation, in order to advance fully-grown immature oocytes to become fertilizable eggs in basal ... -
Nutrient contributions from septic systems in nutrient-sensitive watersheds: Quantifying nutrient inputs, reduction methods, and economic feasibility
(East Carolina University, 2019-04-30)Eutrophication of surface waters is a global issue threatening aquatic ecosystems and recreational opportunities. Nutrient management strategies exist to reduce nutrient inputs from various sources; however, septic systems ... -
OPTIMIZATION OF AN OPTOGENETICALLY ACTIVATED INITIATOR OF APOPTOSIS
(East Carolina University, 2018-05-03)Optogenetic tools provide a window into the world of cell signaling pathways and protein-protein interactions with a precision and elegance that other biological probes can struggle to achieve. The creation of optogenetic ... -
Ordinal-Level Phylogenomics of the Arthropod Class Diplopoda (Millipedes) Based on an Analysis of 221 Nuclear Protein-Coding Loci Generated Using Next-Generation Sequence Analyses
(2013)Background The ancient and diverse, yet understudied arthropod class Diplopoda, the millipedes, has a muddled taxonomic history. Despite having a cosmopolitan distribution and a number of unique and interesting ...
