Using Macroinvertebrate Community Composition To Distinguish Between Natural And Anthropogenic Sedimentation, Amanda E. Schutt Sep 2012

Using Macroinvertebrate Community Composition To Distinguish Between Natural And Anthropogenic Sedimentation, Amanda E. Schutt

Theses and Dissertations

Excess fine sediment from human activity is a major pollutant to streams across the U.S.; however, distinguishing human-induced sedimentation from natural fine sediment is complex. The U.S. Environmental Protection Agency recently implemented a protocol for the quantitative field assessment of human-induced sedimentation using measurements of stream geomorphology. Macroinvertebrate community composition, streambed sediment stability, and sediment composition were studied at 49 sites in the James River watershed in central Virginia. Sediment composition was found to be a stronger driver of community composition than sediment stability. Although I was not able to show that macroinvertebrate metrics were related to sediment stability independently …


Characterization Of Microsatellite Loci And Pilot Population Genetic Analysis In Hickory Shad, Alosa Mediocris, Fnu Vishakha Aug 2012

Characterization Of Microsatellite Loci And Pilot Population Genetic Analysis In Hickory Shad, Alosa Mediocris, Fnu Vishakha

Theses and Dissertations

The hickory shad (Alosa mediocris) is a relatively understudied species of the anadromous fish sub-family Alosinae. This study, the first population genetic analysis of this species, employed 12 neutral microsatellite loci to estimate genetic diversity and population structure in tributaries of lower Chesapeake Bay, Virginia including James River and its tributaries (Appomattox and Chickahominy Rivers), Rappahannock River, and Pamunkey River. Genetic variation was extremely low. Estimates of observed heterozygosity were lower than expected heterozygosity. Significant population structure was detected among the six samples (FST = 0.093, p = 0.01). Effective population sizes were low (Ne ranged from 2 to 134). …

The Road Beyond Suffrage: Female Activism In Richmond, Virginia, Denise Gammon

Theses and Dissertations

This thesis focuses on the continued activism in the YWCA, the Equal Suffrage League and the League of Women Voters after 1920. The work examines the uses of motherhood, social religion, race and traditions as tools for activism and compares the YWCA to the Equal Suffrage League and League of Women Voters after 1920. The date range is roughly from 1915 to 1925.


“The Nonmusical Message Will Endure With It:” The Changing Reputation And Legacy Of John Powell (1882-1963), Karen Adam Apr 2012

“The Nonmusical Message Will Endure With It:” The Changing Reputation And Legacy Of John Powell (1882-1963), Karen Adam

Theses and Dissertations

This thesis explores the changing reputation and legacy of John Powell (1882-1963). Powell was a Virginian-born pianist, composer, and ardent Anglo-Saxon supremacist who created musical propaganda to support racial purity and to define the United States as an exclusively Anglo-Saxon nation. Although he once enjoyed international fame, he has largely disappeared from the public consciousness today. In contrast, the legacies of many of Powell’s musical contemporaries, such as Charles Ives and George Gershwin, have remained vigorous. By examining the ways in which the public has perceived and portrayed Powell both during and after his lifetime, this thesis links Powell’s obscurity …


Is Tdr In Virginia Doa? A Study Of The State Of Transfer Of Development Rights Programs In Virginia, Alissa Akins Jan 2012

Is Tdr In Virginia Doa? A Study Of The State Of Transfer Of Development Rights Programs In Virginia, Alissa Akins

Theses and Dissertations

Transfer of development rights has been approved as a tool to manage growth in Virginia since 2006, yet it has not been widely employed. This tool can be used to direct growth and development at little or no cost to society while simultaneously preserving land for future generations. In an effort to understand the limited use of transfer of development rights programs in Virginia, this research collected information regarding obstacles and limitations to TDR program development and implementation, from every locality in the Commonwealth authorized to employ this tool. Based on findings of pertinent TDR literature, this research outlines the …
