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 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 ...
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 ...
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 ...
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 ...
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 ...
Determining the impact of oil contamination on coupled nitrification-dentirification processes in juncus roemerianus and spartina alterniflora marshes: a greenhouse study

Schneider, Diane (University of Alabama Libraries, 2014)

Salt marshes along the Gulf of Mexico coast can potentially experience frequent exposure to contamination associated with petroleum hydrocarbons. Oiling may affect rates of coupled nitrification-denitrification (CND) in ...
Dopamine homeostasis and environmental risk factors in Parkinson's Disease model

Wright, O'Neil Antonio (University of Alabama Libraries, 2011)

The neurotransmitter dopamine (DA) is an important factor in the regulation of many biological processes, from pleasure and addiction to balance and locomotion. Therefore, understanding and defining the mechanisms and ...
Endocrine disruption in context: dose, compound, and route of exposure interact to affect the multivariate phenotype in mangrove rivulus fish (kryptolebias marmoratus)

Johnson, Elizabeth Lee (University of Alabama Libraries, 2018)

Human activities are having a huge impact on the natural world. Global climate change, urbanization, habitat fragmentation, and pollutants are all contributing to rapid and extensive environmental change and posing significant ...
Factors influencing the distribution of soil Streptomyces spp. and determination of species capable of producing a neurodegenerative metabolite

Watkins, Anna Leigh (University of Alabama Libraries, 2013)

The distribution of the common soil bacteria, Streptomyces, is believed to be influenced by soil characteristics. Studies have indicated that soil properties can be influenced by land use, suggesting different communities ...
Genetic analyses of signal transduction pathways involved in neuromuscular excitability and neurodegeneration in Caenorhabtidis elegans

Kautu, Bwarenaba B. (University of Alabama Libraries, 2012)

Signal transduction pathways regulate many cellular and molecular aspects of the brain including neurotransmission and cell survival. Defects in neuronal signaling can lead to a variety of cognitive and affective disorders ...
Interactive effects of sediment and nitrate subsidies on surface elevation dynamics in a brackish marsh

Nugent, Mollie Alice (University of Alabama Libraries, 2018)

Sediment subsidies to coastal marshes, whether delivered during storm and flood events or via restoration activities (e.g., sediment pumping, dredging or diversions), are critical for marsh elevation maintenance and ...
Inventory of chytrid diversity using a multiphasic approach

Davis, William J. (University of Alabama Libraries, 2016)

Chytrids are an inconspicuous, microscopic early-diverging lineage of fungi. They are among the “dark matter fungi;” little is known about them relative to what is known about Dikarya fungi. Temporary forest ponds are ...
Investigating microbial communities and the environmental factors influencing them in manmade and naturally occurring systems

Shirey, Timothy Brian (University of Alabama Libraries, 2013)

Over the past 50 years, the field of microbial ecology has evolved into one of the most exciting sub-disciplines of biology and has produced many important revelations in the areas of ecology and biotechnology. Much of the ...
Investigating the population genomic effects of inhabiting heterogeneous landscapes across multiple spatial and time scales in montane bumble bees

Jackson, Jason (University of Alabama Libraries, 2019)

Heterogeneous landscapes and the complex combinations of abiotic variation in both terrain and environmental variables such as temperature can drive patterns of genomic divergence and diversification across multiple ...
Investigating the role of molecular chaperones in neurological diseases

Burdette, Alexander Justin (University of Alabama Libraries, 2011)

Most proteins are elaborate three-dimensional structures comprised of amino acids which form specific interactions with each other to bring about the structure of the protein. Thus, it is no surprise that mutating a single ...
Modeling and analyzing cellular defects associated with movement disorders in Caenorhabditis elegans

Xu, Chuan (University of Alabama Libraries, 2018)

As a powerful modern organism, Caenorhabditis elegans has been widely used to study pathologies behind movement disorders including Parkinson’s disease (PD) and dystonia. PD is the second most common neurodegenerative ...
Molecular phylogeny, biogeography, population structure and taxonomy of large barbine minnows (Labeobarbus: Cyprinidae)

Beshera, Kebede Alemu (University of Alabama Libraries, 2012)

The phylogeny, biogeography, population genetics and taxonomy of Labeobarbus (Cyprinidae), a genus of large hexaploid minnows, was estimated by a variety of phylogenetic and population genetics methods. In Chapter 2 ...
