The Effect of Diet on Venom Gene Expression in Tetragnatha versicolor
(East Carolina University, 2017-12-01)Tetragnatha versicolor is an orb weaving spider that can be found throughout North America from Alaska to Nicaragua. This along with the fact the T. versicolor is a habitat generalist means that the species encounters a ... -
The effect of the Achilles tendon moment arm on knee joint contact force
(East Carolina University, 2016-04-29)Musculoskeletal (MSK) models are used extensively in the study of human movement. The validity of a given MSK model is affected by the architectural features of the system. The Achilles tendon moment arm is one important ... -
The Effect of Visual Queues on Social Status Formation and Mauthner Sensitivity in Zebrafish
(East Carolina University, 2017-04-27)Zebrafish of the TLN strain, a genetic variant of the Tüpfel Long-fin (TL) wild-type zebrafish that does not display the trademark striped scale pattern of wild-type zebrafish, but are instead pale, were tested through a ... -
The Effects of Benzoic Acid in C. elegans: Germ Cell Apoptosis
(East Carolina University, 2017-05-05)Benzoic acid is widely consumed by humans everyday through means of fruit juices, soft drinks, pickles, salad dressings and more. However, the health impact of long-term benzoic acid exposure remains largely unknown. This ... -
The effects of climate variability on the timing of ichthyoplankton ingress through Beaufort Inlet, NC, USA
(East Carolina University, 2019-04-30)Climate change has shifted the timing of seasons in many ecosystems worldwide. Species are responding to these shifting seasons with shifts of their own, both in space via migrations and in time via phenology. However, ... -
The Effects of Coal Ash on pH and Microbial Respiration in Neuse River Sediments
(East Carolina University, 2016-04-28)Coal combustion residuals are by-products of energy production resulting from the burning of coal. The coal combustion residuals, or simply coal ash, are then cleaned from the furnaces and added to water to form a thick ... -
The Effects Of Environmental Variation On Individual Variation
(East Carolina University, 2015)Despite general consensus among ecologists that variation is ubiquitous and important in nature, ecological experiments have historically focused on changes in mean response assuming a constant environment and interchangeable ... -
The Effects of Nicotine on Histone Modifications in Carnorhabditis Elegans
(2017-07-13)Early development stages have been known to be very susceptible to certain types of stress. Tobacco smoke is one of these major stresses that will affect them during this stage and can increase how likely they are to become ... -
The Effects of Pharmaceuticals and Personal Care Products (PPCPs) on Predator-Prey Dynamics
(East Carolina University, 2017-12-01)Predators impact community structure and stability by altering the abundance, distribution, and behavior of their prey and through the cascading effects that these changes have on other trophic levels. However, the effects ... -
The Effects of Pharmaceuticals and Personal Care Products on Mosquito Oviposition Site Selection
(East Carolina University, 2018-05-09)The products that humans use every day to shower, drink, prevent sickness, protect their crops, etc. are having an effect on the environment. Pharmaceuticals and personal care products, or PPCPs, have been becoming notable ... -
The effects of Salinity, Depth, and Turbidity on Submerged Aquatic Vegetation (SAV) abundance in Eastern North Carolina
(East Carolina University, 2021-05-03)The state of North Carolina is concerned about the loss of submerged aquatic vegetation (SAV), which is critical fish and wildlife habitat in low-salinity estuaries. Sentinel sites have been established by the East Carolina ... -
The Effects of Social Status on Dopaminergic Regulation of Neural Circuit Activation and Behavior
(East Carolina University, 2017-07-19)Social hierarchies can be observed within communities across many species and allow for proper allocation of resources. When forming social hierarchies, animals that display the most aggressive behaviors generally emerge ... -
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 ... -
