Color Pattern Evolution in the Threespine Stickleback (Gasterosteus aculeatus): Functional, Mechanistic and Synthetic Approaches
(East Carolina University, 2022-07-19)Studies of animal color patterns have provided important insights into the nature of evolution and adaptation. Coloration may be the target of multiple evolutionary processes, including natural selection, intersexual ... -

Concerted gene recruitment in early plant evolution
(East Carolina University, 2008-07)Background: Horizontal gene transfer occurs frequently in prokaryotes and unicellular eukaryotes. Anciently acquired genes, if retained among descendants, might significantly affect the long-term evolution of the recipient ... -
Development of Computational Tools and Resources for Cotton microRNA Analysis
(East Carolina University, 2014)MicroRNAs (miRNAs) are an extensive class of small regulatory RNAs which regulate gene expression at the posttranscriptional levels. miRNAs target genes for mRNA cleavage or translation inhibition based on the complementary ... -
Dodge, Duck, Dip, Dive & Dependence: Using Dodgeball to Explore Frequency Dependent Selection
(2016-09)The term frequency dependence describes scenarios in which the likelihood of an event occurring is strongly tied to how common a particular trait is. Understanding frequency dependence is key to understanding ... -
The evolution of photosynthesis in chromist algae through serial endosymbioses
(2014-12-10)Chromist algae include diverse photosynthetic organisms of great ecological and social importance. Despite vigorous research efforts, a clear understanding of how various chromists acquired photosynthetic organelles has ... -

The Evolution of Women's Roles in the United States Air Force
(2014)Thesis: Women have played a vital role in this country's defense relations throughout the past century and into the present. This paper will explore how women's efforts and roles have evolved from the start of the United ... -
THE EVOLUTION OFHOX [sic] PARALOG GROUP 2 GENE EXPRESSION AND REGULATION IN THE JAPANESE MEDAKA
(East Carolina University, 2011)Hox paralog group 2 (PG2) genes are evolutionarily conserved developmental regulatory genes that function to specify rhombomere (r) and pharyngeal arch (PA) identities in animal embryos. Several rounds of whole genome ... -
The Evolutionary Development of Floating Dry Docks
(East Carolina University, 2012)The floating dry dock represents one of the most technologically advanced structures ever designed to operate in a maritime environment. These indispensable repair facilities provided necessary maintenance to commercial ... -
Genome-wide and molecular evolution analysis of the subtilase gene family in
(2014-12)Background Vitis vinifera (grape) is one of the most economically significant fruit crops in the world. The availability of the recently released grape genome sequence offers an opportunity to identify and analyze some ... -
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 ... -
High major histocompatibility complex class I polymorphism despite bottlenecks in wild and domesticated populations of the zebra finch (Taeniopygia guttata)
(2015-12-01)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 ... -
Lateral Gene Transfer between Bacteria and Trichoderma reesei
(East Carolina University, 2012)Lateral gene transfer (LGT) has played an important role in shaping the `tree of life'. It has promoted evolution by generating gene redundancies, which allow for more freedom in terms of allowed mutations in a genome, ... -
MHC class I variation among wild, domestic and insular populations of the zebra finch (Taeniopygia guttata)
(East Carolina University, 2014)The zebra finch (Taeniopygia guttata) is a passerine bird native to Australia and the Lesser Sunda Islands, with domesticated populations derived from each of these localities. The Lesser Sundas and domesticated zebra ... -
Rectifying Limitations On Species Delineation In Dusky Salamanders : Lineage Detection Using An Ecoregion-Drainage Sampling Regime
(East Carolina University, 2015)The dusky salamanders (Desmognathus) constitute a large, species-rich group, and although a considerable body of literature exists on systematic relationships and adaptive trends, these issues have heretofore been approached ... -
RNA polymerase II CTD Evolutionary Diversity and Associated Protein Identification in Green and Red Algae
(East Carolina University, 2014)In model eukaryotes, the C-terminal domain (CTD) of the largest subunit (RPB1) of DNA-dependent RNA polymerase II is composed of tandemly repeated heptads with the consensus sequence YSPTSPS. Both the core motif and tandem ... -
The Effects of Horizontal Gene Transfer on the Evolution of Land Plants
(East Carolina University, 2023-04-25)This study sought to understand how horizontal gene transfer (HGT) has affected the evolution of land plants. Land plants evolved from charophyte green algae. A list of candidate genes derived from HGT was generated from ... -
