Lack of K-Dependent Oxidative Stress in Cotton Roots Following Coronatine-Induced ROS Accumulation
(2015-05)
Coronatine [COR] is a novel type of plant growth regulator with similarities in structure and property to jasmonate. The objective of this study was to examine the relationship between increased root vitality induced by ...
Citizen Science: Is It Worth Your Time?
(East Carolina University, 2015-12-17)
This dissertation investigated citizen science, a tool that connects the public to the scientific community through research-based projects and education campaigns. Benefits include volunteers adding data to long-term data ...
The genomes of two key bumblebee species with primitive eusocial organization
(2015-04-24)
Background
The shift from solitary to social behavior is one of the major evolutionary transitions. Primitively eusocial bumblebees are uniquely placed to illuminate the evolution of highly eusocial insect societies. ...
Species And Stage Specific Developmental Toxicity Of Endosulfan Exposure In Hyla Cinerea And Ranitomeya Imitator
(East Carolina University, 2015)
During ontogeny, organisms pass through critical periods of heightened vulnerability to disruptive exogenous agents. In organisms with complex life cycles, these developmental windows result in variable susceptibility ...
Gene Expression Divergence Between Zebra Finch (Taeniopygia Guttata) Subspecies And Gene Regulation In Hybrids
(East Carolina University, 2015)
Since the publication of Mayr's Systematics and the Origin of Species, birds have been important model organisms for studies regarding evolutionary processes such as sexual selection and speciation. In this study, I will ...
Fishing For The Evolutionary Bases Of Female Ornamentation
(East Carolina University, 2015)
Sexual dimorphism, or phenotypic differentiation of the sexes, is widespread amongst animals. It is understood mainly in the context of sexual selection, i.e. selection on mating success, with such selection typically ...
Investigating the Role of CtBP in Colorectal Cancer
(2015-04-29)
Recent studies in breast cancer tissue have demonstrated that C-terminal binding protein (CtBP) over-expression induces stem cell-like features and genome instability; whereas CtBP depletion or caloric restriction reverses ...
Hormone Exposure During Pregnancy and Maternal Care
(East Carolina University, 2015-12-17)
It is suspected that prenatal hormones can affect maternal care, which has important implications for the neurological development of pups. To determine if the altered hormone levels affected maternal care, pregnant dams ...
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 ...
High major histocompatibility complex class I polymorphism despite bottlenecks in wild and domesticated populations of the zebra finch ()
(2015-12)
Background
Two subspecies of zebra finch, Taeniopygia guttata castanotis and T. g. guttata are native to Australia and the Lesser Sunda Islands, respectively. The Australian subspecies has been domesticated and is now an ...
