REPRODUCTIVE ISOLATION AND MIMETIC DIVERGENCE IN THE POISON FROG RANITOMEYA IMITATOR
(East Carolina University, 2014)
Understanding the process of speciation requires examination of various stages of its progress. This work focuses on the early stages of population divergence, where populations of a single species may show varying levels ...
Reproductive Plasticity In Two Subspecies Of A Cleistogamous Plant, Triodanis Perfoliata
(East Carolina University, 2015)
Dimorphic cleistogamy is an intriguing reproductive strategy in which a plant produces both closed (cleistogamous), obligately selfing flowers and open (chasmogamous) flowers. Phenotypic plasticity in the production of ...
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 ...
Population Structure Of River Herring In Albemarle Sound, North Carolina, Inferred From Geometric Morphometrics And Otolith Shape Analysis
(East Carolina University, 2015)
Alewife Alosa pseudoharengus and Blueback Herring Alosa aestivalis, collectively known as River herring, use tributaries of the Albemarle Sound, North Carolina as spawning and nursery habitats. Stocks of these anadromous ...
A QUALITATIVE STUDY OF MICROBES IN SERPENTINITE-HOSTED SUBSURFACE ENVIRONMENTS
(East Carolina University, 1/13/16)
Over the last two decades, serpentinizing environments have been studied with regards to the biogeochemistry of these habitats, but significantly less is known about the microbiology within these environments. Serpentinization ...
Determining the Chemical Structure of Brucebactin: The Sole Complex Siderophore Utilized by the Pathogenic Bacterium Brucella Abortus
(East Carolina University, 1/13/16)
Brucellosis is a zoonotic bacterial disease that affects many around the world. There are over half a million new cases each year and prevalence rates in some areas of the world exceed 10 new cases per 100,000 in the ...
Comparison of a Traditional Teaching Model to the SCALE-UP Teaching Model in Undergraduate Biology: A Mixed Method Study
(East Carolina University, 1/13/16)
This project compared a SCALE-UP teaching model to a traditional teaching model. Traditional teaching is now considered a poor motivator for student performance and interests, and the SCALE-UP model was proposed to combat ...
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 ...
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 ...
