Do female Eastern Bluebirds trade-off egg size with clutch size?
Balch, Caroline Grace (East Carolina University, 2017-05-09)Egg size and clutch size are traits that show a fundamental trade-off in life history theory. Producing a larger number of offspring can come at the cost of being able to invest in those offspring. The degree of maternal ... -
Does history matter? : An experimental assessment of whether dragonfly colonization history affects insect biodiversity within ephemeral ponds
Amoroso, Natalie A. (East Carolina University, 2010)Current interactions among species could have an important role in controlling biodiversity. Some studies, however, have shown that the particular time a species arrives at a site during the process of community assembly ... -
DOES THE QUANTITY OF RESOURCES IN THE ENVIRONMENT ALTER THE IMPACT OF MULTIPLE PREDATORS ON THEIR PREY?
Gelles, Tyler R. (East Carolina University, 2013)Predation is an important biological process affecting prey populations and most prey in nature are exposed to multiple predator species. Much research has revealed that the combined effect of multiple predators on their ... -
Drosophila Ovarian Stem Cell Establishment is Regulated by Nuclear Hormone Receptor ftz-f1
Berghout, Hanna E. (East Carolina University, 2017-06-28)Stem cells are a fundamental underpinning of tissue biology. Loss of the self-renewing function of stem cells leads to conditions such as infertility and tissue wasting. Stem cells integrate a variety of signals to maintain ... -
EARLY LIFE HISTORY OF LARVAL RIVER HERRING IN A COASTAL WATERSHED: ABUNDANCE, GROWTH, AND MORTALITY
Ezzard, Anne Dowling (East Carolina University, 2017-12-18)River herring are two closely-related, anadromous fish species, Alewife (Alosa aestivalis) and Blueback Herring (A. pseudoharengus), which have been historically, commercially, and ecologically important along the North ... -
Early Nicotine Exposure Altered Larval Neuromuscular Function and Adult Germline Apoptosis via MiRNA-Dependent Mechanisms
Alston, Robyn D (East Carolina University, 2016-04-29)MicroRNAs fine tune the expression of target genes needed for homeostasis. Our pilot study showed that nicotine altered 17% miRNAs in C. elegans larvae. Here, we investigated the role of microRNAs in mediating nicotine-induced ... -
Ecological effects of rising sea level on shorezone
Kunz, David M. (East Carolina University, 2009)This study examines the ecological effects of sea-level rise on shorezone in the Neuse River estuary and western Pamlico Sound, NC. Shorezone is defined here in an ecohydrological context as the area of wetland that extends ... -

Educational engagement and the environment: Investigating service learning in the nonhuman sciences
Abernethy, Taylor G. (2014)Classic definitions outline service learning as engaging students in experiential education where learning goals are reached when service activities are combined with reflective assignments. In an effort to integrate ... -
THE EFFECT OF CHANGES IN SODIUM CONCENTRATIONS ON MITOCHONDRIA
Heavilin, Teresa (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 ... -

Effect of green tea Polyphenon 60 on microRNA expression in MCF-7 breast cancer cells
Fix, Lindsey Nicole (East Carolina University, 2010)In Western countries, breast cancer is the most common form of cancer and it is the second leading cause of female cancer death in America. The biochemical basis of the observed anti-oncogenic properties of green tea has ... -
Effect of Metformin on the Lifespan and Health Span of Drosophila
Chan, Elizabeth Waynee (East Carolina University, 2023-05-02)Metformin has been the most used drug to treat diabetes for nearly 70 years. It reduces the pressure on the mitochondria from over calorific foods (i.e., fast foods), which termed the Western Diet. Metformin’s ability to ... -
Effect of MicroRNA-34c on Regenerative Axon Growth in Dorsal Root Ganglion Neurons of the Peripheral Nervous System
Raafat, Mohamed Hussien (East Carolina University, 2011)The peripheral nervous system is unique in its ability to regenerate axons after injury. Our lab previously assessed the miRNA expression levels of the regenerating sciatic nerve which indicated miR-34c up-regulation. ... -
Effect of Versican G1 Domain Overexpression on Hyaluronan, Hyaluronidase-2, and Synovial Joint Formation in the Embryonic Chick
Andrews, Kristen Nichole (East Carolina University, 2013)Versican, an extracellular chondroitin sulfate proteoglycan which binds hyaluronan, has been hypothesized to play a role in synovial joint formation in the chick embryo. Several studies have shown versican to be involved ...
