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 ...
Characterization Of 'Fuzzy Tassel' Male Sterility Defects Implicates Novel MiRNA-Regulated Pathways In Maize Stamen Development
(East Carolina University, 2015)
The maize 'fuzzy tassel' ('fzt') mutant is caused by a mutation in 'dicer-like1' and has broad developmental defects. 'dicer-like1' encodes a key enzyme for microRNA (miRNA) biogenesis and many miRNAs are reduced in 'fzt' ...
Assessing The Monophyly Of Red Algae And Green Plants Via Core Conserved Informational Genes
(East Carolina University, 2015)
For well over a century the existence of a monophyletic relationship between red algae and green plants has been debated. Many scholars have sought to address this issue, however, a consistent solution to the problem has ...
Genome-Wide Identification And Expression Analysis Of TCP Transcription Factors In Cotton
(East Carolina University, 2015)
TCP proteins are plant-specific transcription factors known to perform a variety of physiological functions during plant growth and development. In the current study, we performed for the first time the comprehensive ...
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 ...
Metabolic, Physiological, And Behavioral Responses Of Prey To Predation
(East Carolina University, 2015)
Predators are known to cause prey to alter their morphology, life history or behavior in ways that reduce the likelihood of the prey being consumed by the predator. Seldom considered, however, are the consequences of ...
Possible Effects Of Climate Change On Induced Defenses In Tadpoles
(East Carolina University, 2015)
Global climates are changing and the rate of change is expected to increase in the next century. Researchers predict that temporary ponds will be affected, resulting in shorter average hydroperiods (the amount of time a ...
Incorporating Migration and Local Movement Patterns into Management Strategies for Spiny Dogfish (Squalus acanthias)
(East Carolina University, 2015-12-15)
The overall purpose of this dissertation is to increase understanding of migration and movement behaviors associated with a highly migratory elasmobranch species. In particular, I seek to determine whether sufficient ...
THE EFFECTS OF ZOOPLANKTON DISPERSAL ON COMMUNITY ASSEMBLY OF TEMPORARY PONDS
(East Carolina University, 2015-12-10)
The dispersal of individuals among habitat patches is thought to have an important effect on ecological communities as it can influence both population dynamics and community assembly. Though much work on dispersal has ...
Evaluating Land Use Effects On The Stinging Sea Nettle : Chrysaora Quinquecirrha: Are Shoreline Hardening Structures Creating New Habitat For A Nuisance Species?
(East Carolina University, 2015)
There is considerable debate as to whether global jellyfish populations are experiencing an overall population growth due to human activities or have been pulsing in a long-term natural rhythm. Empirical data to support ...
