Bacillus anthracis Co-Opts Nitric Oxide and Host Serum Albumin for Pathogenicity in Hypoxic Conditions

St. John, Steve (2013-09-16)

Bacillus anthracis is a dangerous pathogen of humans and many animal species. Its virulence has been mainly attributed to the production of Lethal and Edema toxins as well as the antiphagocytic capsule. Recent data indicate ...
Bacterial Community Composition and Physicochemical Properties of Soils in Created and Natural Wetlands in Virginia

Peralta, Rita M (2011-05-31)

Soil properties are often studied along with vegetation to examine the status of ecosystem development in created wetlands. Soil bacterial communities are essential to the biogeochemical processes in wetlands, yet are ...
Basic Helix Loop Helix Enhancer 40 in Neuronal Excitability and Synaptic Plasticity

Hamilton, Kelly Andrew (2016)

This dissertation describes the role of the Basic helix loop helix enhancer 40 (Bhlhe40) transcription factor in the adult murine brain at the molecular, cellular, network, and behavioral levels. Studies for this dissertation ...
Behavioral and Physiological Dynamics of Musth in Asian Elephants

LaDue, Chase Andrew (2022)

In-situ and ex-situ populations of Asian elephants (Elephas maximus) are unsustainable in the long-term and require integrative approaches to address issues impacting their conservation status. Male elephants pose distinct ...
Behavioral Assessment of the Clouded Leopard (Neofelis nebulosa); A Comparative Study of Reproductive Success

Fazio, Jilian (2010-05-11)

This thesis details a behavioral assessment of the clouded leopard (Neofelis nebulosa). The clouded leopard is classified as “Vulnerable” by the International Union for Conservation of Nature‟s (IUCN 2010) Endangered Species ...
A Behavioral Investigation of the Thermal Solar Niche

Boyer, Emma Gerald (2015-01-29)

The means by which a species survives in different environmental conditions is central to thoroughly understanding its ecology, evolution, and conservation. As we face a warming climate, developing a more comprehensive ...
Behavioral, Hormonal, and Tissue Biomarkers of Stress Regulation in Young Adult Rats after Different Schedules of Early Life Stress: Eustress versus Distress

Stoneham, Emily T. (2014-09-18)

Individuals experiencing stressful early life environments due to isolation, abuse, or neglect, are predisposed not only toward physically debilitating illnesses (coronary and metabolic diseases) but also potentially ...
Benthic Cyanobacteria Production and Abundance in the Tidal Occoquan River

Mohney, Samantha

The freshwater Tidal Potomac River has an extensive history of eutrophication and planktonic cyanobacterial harmful algal bloom (cHAB) occurrence. Improvements and upgrades to local sewage treatment facilities have helped ...
Benthic Macroinvertebrate Communities as Indicators of Reconstructed Freshwater Tidal Wetlands in the Anacostia River, Washington, D.C.

Brittingham, Kevin D (2011-05-25)

Considerable work has been conducted on the benthic communities of inland aquatic systems and brackish water estuarine wetlands, but there remains a scarcity of effort on freshwater tidal wetlands. This study characterized ...
Bioaccumulation of Selected Pharmaceuticals and Personal Care Products between Primary Producers and Consumers in the Tidal Freshwater Potomac River

Czarnecki, Julia

Increased concentrations of pharmaceuticals and personal-care products (PPCPs) and their metabolites flow into our waterways every year and pose a threat to aquatic ecosystems. This study examined the bioaccumulation and ...
Bioavailability of Persistent Organic Pollutants in Fish from Gunston Cove (Potomac River Watershed, Virginia)

Moody, Adam (2013-08-16)

Three classes of Persistent Organic Pollutants (POPs): Polycyclic Aromatic Hydrocarbons (PAHs), Polychlorinated Biphenyls (PCBs) and Organochlorine Pesticides (OCPs) were investigated in aquatic biota and bed sediments ...
Biogeography and Phylogeography of Mammals of Southeast Asia: A Comparative Analysis Utilizing Macro and Microevolution

Hawkins, Melissa T. R. (2015-09-18)

The tropical rainforests of Southeast Asia are some of the most threatened ecosystems on the planet, yet few systematic studies have been done to evaluate the mammalian communities with respect to biogeographic and ...
The Biological and Economic Benefits of Shade Coffee Plantations in the Blue Mountain, Jamaica W.I.

Davis, Herlitz Alphonso (2013)

Although many studies have touted the conservation value of coffee agroecosystems for migratory and resident birds, gaps do still exist in our knowledge about the suitability for birds and the economic benefit of fruit ...
Biophysical Characterization and Mass Spectral Identification of Cationic Antimicrobial Peptides

Juba, Melanie Lynn (2014-09-23)

Cationic antimicrobial peptides (CAMPs) are a highly sequence and structurally diverse group of peptides that exert antibacterial, antifungal and antiviral effects. They have recently been of interest due to their therapeutic ...
Biostratigraphic and Stable Isotopic Study of Selected Foraminifera from the Turonian Lindi Formation, Southeastern Tanzania (Tanzania Drilling Project Site 34 Drill Core)

Petruny, Loren M

This thesis examines samples of foraminiferal specimens from selected depths within the site 34 drill core of the Tanzanian Drilling Project (TDP), including 3D imaging, for the purposes of biostratigraphy and geochemical ...
Biothreat Detection by Random Oligomer-Based Microarray

Diggans, James C. (2009-08-24)

Current biosensors are primarily based upon previous observations: they detect organisms known to be pathogenic. Future biowarfare agents, however, are likely to contain completely novel or re-engineered proteins and ...
Black Hole Mass Determination Using X-Ray Data

Jang, Insuk (2014-08)

Supermassive black holes are located at the center of basically every galaxy and their mass appears to be tightly correlated with several galaxy properties, suggesting that black hole and galaxy growths are linked together. ...
Blockbuster Emergence in Entertainment Platform Markets: Modeling the History of the Video Game Industry in North America.

Ernesto Lhuillier (2019)

Entertainment markets are typically dominated by blockbusters; which are characterized for being highly popular and financially successful over a vast majority of failures. Today, the entertainment industry has shifted ...
BRCA1 Functions as a Novel Transcriptional Cofactor in HIV-1 Infection

Güendel Sánchez, Irene (2014-09-23)

Viruses have naturally evolved elegant strategies to manipulate host cellular machinery, including ways to hijack cellular DNA repair proteins to aid in their own replication. Retroviruses induce DNA damage through integration ...
Bridging the Gap between Research and Decision-Making: Empirical Evidence from a Case Study of Gray Wolf (Canis lupus) Management in the U.S.

Thornhill, Jennifer Lynn (2014-05)

Does science inform decision-making? This question has been the subject of much attention across a wide range of scientific fields generating hundreds, if not thousands, of publications. In this dissertation, the gap between ...
