Phylogeography and Mating System of Spiraea Virginiana Britton: A Multi-Scale Exploration of the Biology of a Threatened Species 2010 2820 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 4490 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 1691 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 661 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 294 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 179 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...
Taxonomic Studies In The Aquatic Moss Genus PLATYHYPNIDIUM (BRACHYTHECIACEAE) 2006 46 The generic affinities of the aquatic moss genus Platyhypnidium were investigated by several analytic techniques: traditional light microscopy, phenetic analyses of dimensional measurements (Analysis of Variance and principal Components Analysis), an...
Phylogeography Of CAREX EBURNEA (CYPERACEAE) And The Systematics Of The CAREX EBURNEA Complex 2005 60 The Carex eburnea complex (Carex Section Albae) is comprised of two named species, C. eburnea Boott and C. mckittrickkensis Ball. Carex eburnea is widely distributed on limestone in North America and C. mckittrickkensis exists at a single station in ...
Biogeographical, Ecological, Morphological, And Micromorphological Analyses Of The Species In The Hexastylis Heterophylla Complex 2004 29 The genus Hexastylis Raf. (commonly known as "Wild Ginger" or "Little Brown Jugs") is comprised of nine species that are distributed throughout the southeast of North America. Blomquist (1957) and Gaddy (1987) both recognized a group of eight Hexasty...
A Floristic Survey And Wetland Vegetation Analysis Of Tater Hill Preserve 2007 28 A vascular plant inventory and vegetation analysis of Tater Hill Preserve, Watauga County, North Carolina was conducted during the growing seasons of 2002-2004. The preserve encompasses approximately 205 ha within the Amphibolite Macrosite of the Blu...
An Ecohydrological Framework For The Functional Assessment Of Southern Appalachian Wetlands 2008 22 This study integrates various data sources, considers the need for time and resource efficient assessment methodologies and the multiple geographic scales involved in the maintenance of watershed functions like water storage and water quality in a GI...
