A genetic and neurochemical analysis of dopamine regulation in drosophila melanogaster of human neurodegenerative disorders and neuroinflammation

Ajjuri, Rami Rifat (University of Alabama Libraries, 2015)

Dopamine, a critical neurotransmitter, regulates dozens of vital biological functions within the human brain and throughout the body, and therefore disruptions in dopamine signaling result in a wide range of behavioral, ...
A multiphasic approach to investigating microbial community structure and function in oiled salt marshes and weathered crude oil products during the Deepwater Horizon oil spill

Flournoy, Nikaela Yarbrough (University of Alabama Libraries, 2017)

On April 20, 2010, a catastrophic incident occurred on the exploratory BP oil rig, Deepwater Horizon (DWH). At the time of the Macondo wellhead blowout, the extent of ecological and economic devastation in northern Gulf ...

A phylogeny and study of floral traits in the neotropical genus Gasteranthus (Gesneriaceae)

Coleman, Cassandra Lynn (University of Alabama Libraries, 2012)

The genus Gasteranthus (Gesneriaceae), with 41 currently described species, including 3 subspecies, occurs in Central and South America. This genus has a center of diversity in Ecuador and is comprised of herbs or subshrubs ...
A two-stage bioreactor for the production of polyhydroxyalkanoates

Durfey, Samantha L. (University of Alabama Libraries, 2016)

The efficacy of ethyl 3-ethoxybutyrate (EEB) to serve as a biofuel additive has recently been investigated. This biofuel, which can be blended with gasoline or diesel, is made from polyhydroxyalkanoates (PHA). However, PHA ...
An integrative approach to resolving taxonomic controversy and reconstructing the evolutionary history of the southern leopard frog (rana sphenocephala)

Newman, Catherine Elizabeth (University of Alabama Libraries, 2009)

This study presents an integrative approach to phylogeography and species delimitation that includes genetics, ecology, and morphology and applies this approach to the study system Rana sphenocephala, a widely distributed ...
Analysis of genetic and environmental factors in neurodegenerative disease

Hall, Marleshia Dorcell (University of Alabama Libraries, 2016)

The incidence of neurodegenerative diseases including Parkinson’s, Alzheimer’s, and Huntington’s disease is ever-increasing. Therefore, it is essential that we understand the mechanisms behind the pathology of these ...
Aquatic community organization in a diverse floodplain river fish fauna of the southeastern United States

Kennedy, Thomas Brian (University of Alabama Libraries, 2009)

I investigated the ecology of native fishes resident to the unregulated Sipsey River in west-central Alabama for 20 consecutive months. Using a synoptic sampling approach, I collected > 19,000 fishes representing 77 of ...
Assessing seasonal and potential hydrocarbon and dispersant influences on coastal Alabama microbial populations

Powell, Jessica Tierce (University of Alabama Libraries, 2012)

The catastrophic oil spill on April 20, 2010, in which an estimated five million barrels of crude oil were released into the Gulf of Mexico from a depth of 1544 m, has been postulated to promote a bloom of disease causing ...
Assessing the relative influence of abiotic and biotic impacts to range limits in two terrestrial salamander species (Plethodon glutinosus and Plethodon mississippi)

Cunningham, Heather Renee (University of Alabama Libraries, 2010)

My research investigated the impact of abiotic factors and species interactions on the geographic distribution of two terrestrial salamander species, Plethodon glutinosus(Northern Slimy Salamander) and P. mississippi ...
Assessment of the bacterial communities associated with invasive indo-pacific lionfish, a study of biogeography and host-microbe interactions

Stevens, Julia L. (University of Alabama Libraries, 2014)

The inundation of lionfish into the Western Atlantic, Caribbean Sea, and Gulf of Mexico is considered one of the worst recorded marine invasions. Native to the Indo-Pacific, lionfish were introduced through the aquarium ...
Biodiversity and molecular systematics of subaerial algae from Africa and the neotropics

Allali, Haj Abdeslam (University of Alabama Libraries, 2011)

Algae are a large and diverse group of photosynthetic organisms that range in size from microscopic unicellular to multicellular forms. They usually inhabit marine and freshwater habitats. However, some are terrestrial and ...
Biodiversity and systematics of subaerial algae from the neotropics and Hawaii

Lam, Daryl W. (University of Alabama Libraries, 2010)

Algae are a diverse assemblage of photosynthetic organisms that includes prokaryotes (Cyanobacteria) as well as unicellular and multicellular eukaryotes. They inhabit freshwater, saltwater, and terrestrial ecosystems. ...
Blue crab residency and migration in the Mobile Bay estuary: a stable isotope study investigating connectivity

Vedral, Anthony James (University of Alabama Libraries, 2012)

The blue crab (Callinectes sapidus) is an important commercial species throughout Gulf of Mexico. We used carbon and nitrogen stable isotopes from fast and slow turnover tissues to investigate residency and migration of ...
Characterization of the regions surrounding zooA-zif and lss-lif

Gargis, Amy Shirley (University of Alabama Libraries, 2010)

Staphylococcus simulans biovar staphylolyticus produces the staphylolytic enzyme lysostaphin and it is the only known lysostaphin producer within the species. Genes with similarity to the lysostaphin gene (lss) and the ...
Characterization of the roles of phosholipase B1 and the cyclic-AMP (cAMP)-protein kinase A (PKA) pathway in nutritional and osmotic stress response in Schizosaccharomyces pombe

McInnis, Brittney (University of Alabama Libraries, 2012)

Physiological stress is a reality faced by all cells. Even though these stresses are often disruptive of normal cellular function, cells must adapt to the stressor or perish. This study utilizes the model organism ...
Characterization of the Streptococcolytic enzyme zoocin A and its resistance factor, zif

Gargis, Shaw Roger (University of Alabama Libraries, 2010)

Zoocin A is a bacteriolytic enzyme produced by Streptococcus equi subsp. zooepidemicus 4881 that is able to hydrolyze the cell walls of some streptococcal species. The site of action on peptidoglycan by zoocin A was ...
Compound specific isotope analysis of amino acids in freshwater ecosystems: insights and applications

Ghosh, Prarthana (University of Alabama Libraries, 2014)

Investigation of the δ^13 C and δ^15 N of individual compounds, commonly referred to as compound specific isotope analysis (CSIA), along with traditional techniques such as stomach content, dietary tracers, and bulk stable ...
Conservation, life history and systematics of Leptoxis rafinesque 1819: (Gastropoda: Cerithioidea: Pleuroceridae)

Whelan, Nathan V. (University of Alabama Libraries, 2013)

Freshwater gastropods of the family Pleuroceridae are incredibly important to the health of freshwater ecosystems in the southeastern United States. Surprisingly, however, they are one of the most understudied groups of ...
Constructing a graphical model of the Drosophila melanogaster metabolome

Oza, Vishal Himanshu (University of Alabama Libraries, 2020)

Metabolomics, a relatively late entrant in the ’omics’ pyramid, aims to capture a complete snapshot of the metabolome of an organism at any given point in time. Recent advances in mass spectrometry techniques have allowed ...
