A study of composition, abundance, and fatty acid profiles of zooplankton in Albemarle Sound and Chowan River, North Carolina during spring and early summer
(East Carolina University, 2014)
In the Albemarle Sound and Chowan River, North Carolina, river herring (alewife and blueback herring) once comprised a commercially important fishery; however, this fishery has since collapsed and a moratorium on river ...
A Synthesis of Red Drum Feeding Ecology and Diets from North Carolina and South Carolina
(East Carolina University, 2014)
The trophic interactions of the red drum Sciaenops ocellatus have been previously researched. However diet data on the largest adults (>750mm TL) are very limited. As fisheries management moves towards a goal of multi-species ...
Characterizing the Expression Pattern of miR167-Regulated ZmArf3 and ZmArf30 in Maize Inflorescences
(East Carolina University, 2014)
Plant growth and development depends on the activity of meristems, pools of stem cells that generate leaves and other organs. Maize (corn) produces two inflorescences, the tassel and ear, which are patterned by a series ...
Using student motivation to design groups in a non-majors biology course for team-based collaborative learning : Impacts on knowledge, views, attitudes, and perceptions
(East Carolina University, 2014)
The importance of student motivation and its connection to other learning variables (i.e., attitudes, knowledge, persistence, attendance) is well established. Collaborative work at the undergraduate level has been recognized ...
The Acquisition of a Plastid by Haptophytes, Cryptophytes, and Photosynthetic Heterokonts
(East Carolina University, 2014)
Red algae and green plants are known to have obtained their photosynthetic organelles, or plastids, through the endosymbiotic adoption of cyanobacteria. It is still widely debated as to how other eukaryotic alga such as ...
The Effects of Crude Oil and Chemical Dispersant Exposure on Danio rerio (zebrafish) Embryonic Development
(East Carolina University, 2014)
Crude oil has been shown to cause defects in cardiovascular development in a variety of teleost species. We used the zebrafish, Danio rerio as a model to test the effects of oil and dispersant on cardiac development and ...
Spatial Ecology and Seasonal Habitat Use of the King Rail (Rallus elegans) along the Atlantic Coast
(East Carolina University, 2014)
TThe King Rail (Rallus elegans) continues to experience population declines throughout its range. Due to its secretive nature and occupancy of densely vegetated marshes, little is known about the behavior and ecology of ...
Assessing Morphological Variability in Silversides along the Mid-Atlantic Bight
(2015)
Inland silversides (Menidia beryllina) and Atlantic silversides (Menidia menidia) are ubiquitous fishes in the estuaries on the east coast of the United States. These species are very similar in appearance and may share ...
Assessing cellular and genomic damage from environmental nickel using a GFP containing strain of Caenorhabditis elegans
(East Carolina University, 2013)
Nickel is a naturally found mineral that has become widely used for many electronic devices. As use and subsequent discarding of nickel containing products continues exposure to nickel increases. Nickel can cause external ...
THE EFFECT OF CHANGES IN SODIUM CONCENTRATIONS ON MITOCHONDRIA
(2015-05-01)
Atherosclerosis, hardening of the arteries, is the major cause of stroke, peripheral artery disease and heart attack. . Overproduction of superoxide anions in mitochondria can give rise to atherosclerosis. Superoxide anions ...
