The Evolution of Organ Shape : Distal Tip Cell Migration and Gonadogenesis in Nematodes
(East Carolina University, 2013)Animals display a variety of shapes in nature. The different shape of homologous organs allows them to adopt different functions and therefore, allows animals to live in different ecological niches. However, little is ... -
The evolution of parental care and egg size: a comparative analysis in frogs
(East Carolina University, 2006-03-22)The evolution of parental care and egg size has attracted considerable attention and theoretical debate. Several different hypotheses have been proposed concerning the trajectories of parental care and egg size evolution ... -
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 ... -

Evolution of Plant Nucleotide-Sugar Interconversion Enzymes
(2011)Nucleotide-diphospho-sugars (NDP-sugars) are the building blocks of diverse polysaccharides and glycoconjugates in all organisms. In plants, 11 families of NDP-sugar interconversion enzymes (NSEs) have been identified, ... -
Evolution of the RNA polymerase II C-terminal domain
(East Carolina University, 2002-04-30)In recent years a great deal of biochemical and genetic research has focused on the C-terminal domain (CTD) of the largest subunit (RPB1) of DNA-dependent RNA polymerase II. This strongly conserved domain of tandemly ... -
Experimental design and statistical rigor in phylogenomics of horizontal and endosymbiotic gene transfer
(2011)A growing number of phylogenomic investigations from diverse eukaryotes are examining conflicts among gene trees as evidence of horizontal gene transfer. If multiple foreign genes from the same eukaryotic lineage are found ... -
Experimental evidence for predator learning and Müllerian mimicry in Peruvian poison frogs (Ranitomeya, Dendrobatidae)
(East Carolina University, 2013)Poison frogs are characterized by bright coloration, striking patterns, and toxicity; they have thus become a classic example of aposematism. Ranitomeya imitator mimics three congeneric model species (R. fantastica, R. ... -
EXPLORING THE BYSTANDER EFFECT FOLLOWING VERY LOW DOSE RADIATION
(East Carolina University, 2010)Bystander effects are defined as the phenomenon in which unirradiated cells respond biologically when their neighbors are irradiated. The exact mechanisms of these cellular responses are still not known, especially in ... -
Exploring the Potential of Sucralose as a Cryopreservative for Red Blood Cells
(East Carolina University, 2017-12-11)Cryopreservation is a technique that involves freezing living cells to preserve them in long-term storage. Freezing and preserving living cells would not be possible without the assistance of cryopreservatives. Many ... -
Exploring the roles of horizotnal gene transfer in metazoans
(East Carolina University, 2016-07-20)Horizontal gene transfer (HGT; also known as lateral gene transfer, LGT) refers to the movement of genetic information between distinct species by overcoming normal mating barriers. Historically HGT is only considered to ... -
Exposure To Elevated Prenatal Testosterone Metabolites Induce Autism-Like Behavior In Rats : Evidence For The Extreme Male Brain And Implications For Human Health
(East Carolina University, 2015)Neurodevelopmental disorders such as autism spectrum disorder (ASD) originate during early brain development and are the result of complex interactions between genetic and environmental factors. Disruptions in the prenatal ... -
An Extensive New Literature Concerning Low-Dose Effects of Bisphenol A Shows the Need for a New Risk Assessment
(East Carolina University, 2005-08)Bisphenol A (BPA) is the monomer used to manufacture polycarbonate plastic, the resin lining of cans, and other products, with global capacity in excess of 6.4 billion lb/year. Because the ester bonds in these BPA-based ...
