Characterization of iron uptake into mitochondria of Saccharomyces cerevisiae
(2015-07-29)
Iron is abundant in the environment in the oxidized ferric state. However this form is not bioavailable. Cells require soluble ferrous iron and therefore many reduction strategies have evolved. FRE5 encodes a putative iron ...
Elucidating Biological Questions with Bioinformatics Tools, with a Case Study of Tube Worm Hemoglobin
(2015-07-24)
The goal of my Master’s Thesis research was to utilize sequenced data in conjunction with new data to investigate the sulfur binding hemoglobin of the annelid family Siboglinidae. To accomplish this, multiple bioinformatic ...
Identification of new components involved in shoot gravitropism in Arabidopsis thaliana
(2015-07-24)
Plants can reorient their growth according to environmental cues such as light, water, nutrients, gravity etc. Shoots (hypocotyls and inflorescence stems) of the plants exhibit negative gravitropism. Germinating seeds are ...
The Role of SCARECROW-LIKE 3 in Salt Tolerance During Germination and Seedling Development in Arabidopsis thaliana
(2010-07-20)
Salinity is a stress factor that results in reduced crop productivity. As much as three hectares of arable land is lost due to salinity per minute. With an increasing world population and shrinking arable land, world crop ...
Investigations of Neural Ontogeny in the Larval Oyster Crassostrea virginica and the nudibranch Berghia verrucicornis: A Histological and Immunohistochemical Approach
(2010-06-07)
Bivalves are a diverse group of molluscs that inhabit both marine and freshwater habitats. These animals play a vital role in the success of entire aquatic ecosystems by filtering the water and providing structural complexity ...
Discovery and Characterization of Novel Antibiotic Synthesis and Resistance Determinants from Diverse Microbial Metagenomes
(2010-07-09)
The application of metagenomics to investigate the genetic and functional diversity of as-yet-uncultured microorganisms from natural environments has been one of the most significant breakthroughs in molecular microbiology. ...
Condition Dependence and Status Signaling Function of Structural Coloration in the Eastern Bluebird (Sialia sialis)
(2010-11-16)
I examined the relationship between blue feather coloration, nutritional condition, and status signaling in eastern bluebirds (Sialia sialis). I quantified nutritional condition by measuring growth rates of tail feathers ...
Redescription and Morphometric Analysis of Isorineloricaria (Siluriformes:Loricariidae)
(2010-12-13)
In this study, the genus Isorineloricaria Isbrücker 1980 is resurrected and redescribed. The complex history of the genus is reviewed. Isorineloricaria is diagnosed from Hypostomus by an elongated caudle peduncle, elongate ...
Rapid Wound Repair in the Ctenophore Mnemiopsis spp.
(2010-11-04)
The ability to quickly and efficiently close a wound is an integral part of any organism’s ability to survive. Marine organisms are exposed to numerous environmental pressures that demand the need for a rapid repair ...
Consequences of low-head dams on crayfish distribution and gene flow in Alabama stream
(2010-08-03)
Dams are numerous in many eastern US streams, and instream physicochemical and biotic impacts of dams can alter flow and sediment regimes and channel geomorphology as well as reducing longitudinal movement by fishes and ...
