Phylogeography and Mating System of Spiraea Virginiana Britton: A Multi-Scale Exploration of the Biology of a Threatened Species 2010 2781 This thesis explores the genetic structure and reproductive biology of Spiraea virginiana, a threatened shrub endemic to 2nd and 3rd order drainages in the southern Appalachians and Cumberland Plateau. I analyzed a dataset created with eight Inter S...
Developing New Morphological, Geographic, and Molecular Tools to Circumscribe Hexastylis naniflora 2013 4339 Hexastylis Rafinesque is a genus of 11 species that is broken down into three groups. The Hexastylis Heterophylla subgroup contains three closely related species: H. heterophylla Small, H. minor Blomquist, and H. naniflora Blomquist. Hexastylis nanif...
Using cpDNA to Assess Species Delimitation between Liatris helleri Porter (Asteraceae) and Liatris turgida Gaiser 2013 1671 Liatris helleri is a federally-threatened perennial species endemic to nine populations in Western North Carolina. Evidence suggests that L. helleri is morphologically indistinguishable from L. turgida, and thus should be subsumed into a single speci...
Environmental Niche Divergence In The Kalmia Lineage: Integrating Phylogeny, Community Composition And Ecology To Understand Patterns Of Regional Plant Diversity 2018 630 The ongoing synthesis of the formerly disparate fields of ecology and evolution is resulting in a proliferation of insights, highlighting the interdependence and feedback between ecological and evolutionary processes. There is increasing evidence tha...
Species Delineation Of Two Imperiled Wild Gingers (Asarum Contracta And A. Rhombiformis) Using Ecological, Morphological, And Molecular Techniques 2008 227 Asarum contracta and A. rhombiformis are closely related species and both are in need of protection. Floral differences between A. contracta and A. rhombiformis have been inconclusive in separating them as distinct taxa and there is no published ecol...
Bibliography, Spatial Distribution And Richness Patterns Of North Carolina Floras 2009 139 This thesis utilizes primary biodiversity literature to answer questions related to macroecology and the spatial patterns of floristic exploration. Vascular plant checklists (floras) supply key information for biodiversity studies by providing a comp...
