Conspecific pollen precedence and its contribution to speciation in Triodanis perfoliata
(2015)Speciation is the process by which one species diverges into two distinct species. To fully understand speciation, it is important to understand reproductive isolation. Reproductive isolation, the inability of two individuals ... -
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 ... -
Phenotypic and Genetic Divergence among Poison Frog Populations in a Mimetic Radiation
(2013)The evolution of Müllerian mimicry is, paradoxically, associated with high levels of diversity in color and pattern. In a mimetic radiation, different populations of a species evolve to resemble different models, which can ... -
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 ... -
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 ...
