Impacts Of Educational Programming At Dolphins Plus On Visitor Knowledge, Attitude And Behavior, Carley Rice
Masters Theses, 2010-2019
Zoos, aquariums, and similar institutions have been transitioning for many years from venues of entertainment to institutions of informal environmental education. This transition has led to these institutions claiming missions of conservation and education. The conservation education impacts of zoos and aquariums are not well understood. The literature is limited and at times inconclusive. Claims of conservation and education should be formally evaluated through survey research projects to determine validity. These types of studies will shed light on these institutions and aid in improving educational programs to best benefit conservation of wildlife, habitats and the environment. The purpose of this …
The Combined Effects Of Soil Fertility And Soil Amendments On The Growth And Mycorrhizal Associations Of American Ginseng (Panax Quinquefolius), Emily Ann Murray
The Combined Effects Of Soil Fertility And Soil Amendments On The Growth And Mycorrhizal Associations Of American Ginseng (Panax Quinquefolius), Emily Ann Murray
Masters Theses, 2010-2019
Arbuscular mycorrhizal fungi (AMF) are fungi that form symbiotic associations with 70-90% of plant families. They are known to allow for the extension of the root system as well as an increase in plant size by assisting with the uptake of nutrients such as nitrogen and phosphorus. The role that AMF play in plant health and success has led to the development of commercial inoculum, which is used in agricultural settings. However, soil fertility, and soil amendments are known to affect AMF and plant associations. This study intends to look at how cultivated American Ginseng seedlings are affected by commercial …
Using Capture-Mark-Recapture Techniques To Estimate Detection Probabilities & Fidelity Of Expression For The Critically Endangered James Spinymussel (Pleurobema Collina)., Alaina C. Esposito
Using Capture-Mark-Recapture Techniques To Estimate Detection Probabilities & Fidelity Of Expression For The Critically Endangered James Spinymussel (Pleurobema Collina)., Alaina C. Esposito
Masters Theses, 2010-2019
The critically endangered James Spinymussel (Pleurobema collina) is a species of freshwater mussel endemic to Virginia’s James and Dan River basins. In the last 20 years, P. collina has experienced a substantial decline in numbers and currently occupies approximately 10% of its original habitat; however, little information is known about this species to assist in conservation. A 230-meter reach of transitional habitat in Swift Run was selected for repeat observations to estimate detection probabilities using a Capture-Mark-Recapture framework. In June 2014, visual scouting began to locate and tag P. collina (including other mussels in the community) with PIT …
Impacts Of Consumer Horticulture On Stormwater And Nutrient Management: Investigating Public Perception, Knowledge, And Practices In The Shenandoah River Watershed, Christopher P. Parker

The South Fork Shenandoah River is a tributary to the Chesapeake Bay that is a significant contributor to nitrogen and phosphorus that enter the Bay and leads to increased eutrophication. These nutrients also cause problems in the South Fork Shenandoah River. The United States Environmental Protection agency has implemented strict regulation to reduce nutrients entering the Bay by developing the Chesapeake Bay TMDL. While the TMDL has strict regulation on wastewater treatment, agriculture, and industry, there are still sources of nutrients entering the Bay through unregulated sources. Urban/suburban runoff is one of these sources, particularly runoff from home owner’s lawns. …
Examining The Effectiveness Of Ecotourism As A Funding Source For Protected Area Management In Guyana, Jordan S. Flagel
Examining The Effectiveness Of Ecotourism As A Funding Source For Protected Area Management In Guyana, Jordan S. Flagel
Masters Theses, 2010-2019
Protected areas in tropical rainforests serve many important ecosystem services, including carbon sequestration. These areas are often in need of donor or grant funding to operate as governments in tropical forested countries are not always able to provide adequate funds for protection. This paper focuses on the Iwokrama International Center for Rainforest Conservation and Development in the South American country of Guyana, which has had funding issues since the global economic crisis of 2008 and an accompanying shift in donor country financial priorities. Increasing the amount of sustainable ecotourism in the Iwokrama reserve was identified as a potential source for …
Colloidal And Biological Properties Of Triscationic Amphiphiles With One Or Two Tails, John N. Marafino
Colloidal And Biological Properties Of Triscationic Amphiphiles With One Or Two Tails, John N. Marafino
Masters Theses, 2010-2019
The decline in the development of novel antimicrobials, combined with the misusage and over prescription of antibiotics, has contributed to the increasing prevalence of antimicrobial-resistant infections. Thus development of effective novel disinfectants could reduce the transmission of pathogens and decrease the risk of infection by antibiotic resistant organisms. The antimicrobial activity of amphiphiles, compounds with hydrophobic and hydrophilic regions, was first reported in 1935, and has influenced the synthesis of amphiphiles with variations in structure. In this study, three series of amphiphiles were synthesized by two subsequent Menshutkin reactions. Each amphiphile contains one or two hydrocarbon tails ranging from 8 …
