Understanding genomic evolution and segregation distortion in solanaceae : a COSII linkage map in Nicotiana
(University of Missouri--Columbia, 2009)
Genetic linkage maps are excellent tools to investigate genomic evolution, genomic structure and quantitative trait loci. In our study, we created comparative linkage maps in a reciprocal cross between Nicotiana longiflora ...
Effects of riparian buffer width on stream salamander populations in the southern Appalachian Mountains
(University of Missouri--Columbia, 2008)
Salamanders in the Appalachian region have been extensively studied, but the majority of research assessing the impacts of logging has focused on terrestrial species that are not dependent on stream habitats for egg ...
Identification, characterization and use of novel thermogenetic tools in drosophilia melanogaster
(University of Missouri--Columbia, 2019)
Extrinsic control of neural activity is necessary to decipher the neural mechanisms underlying behavior. Molecular tools that employ light (optogenetics) or temperature (thermogenetics) are primarily used for extrinsic ...
Amphibian metamorphosis and juvenile terrestrial performance following chronic cadmium exposure in the aquatic environment
(University of Missouri--Columbia, 2005)
Effective amphibian conservation requires an understanding of how populations respond to specific natural and anthropogenic factors. Chemical contaminants are among the known sources of acute and chronic stress and have ...
Mechanisms of photoreceptor mediated responses in photomorphogenesis and phototropism
(University of Missouri--Columbia, 2018)
Photoreceptor facilitated light perception provides plants with critical environmental information from which they can direct their growth. We investigated the early photomorphogenic responses in Glycine max and Glycine ...
Friends in high places : ecology of mycorrhizal associations in alpine plant communities
(University of Missouri--Columbia, 2010)
Mutualisms are ubiquitous in nature, yet these interactions often vary in strength and persistence. This variation raises the questions of what determines whether mutualisms persist or vanish, and how does variation in the ...
Tales of an 'invisible' life stage : survival and physiology among terrestrial juvenile ambystomatid salamanders
(University of Missouri--Columbia, 2019)
The vital rates (e.g., survival, growth, and reproduction) of distinct life stages within a species are known to influence the growth and persistence of populations. As such, studies describing stage-specific vital rates, ...
Coupling, membrane conductance, and ion channel mRNA profiles in the establishment and maintenance of network activity in the crustacean cardiac ganglion
(University of Missouri--Columbia, 2021)
Neural networks produce critical rhythmic behaviors throughout an animal's lifespan, despite growth, differing environments, and changes in physiological state. This requires networks which balance stability in their ...
Quantitative biological studies at cellular and sub-cellular level
(University of Missouri--Columbia, 2007)
We developed a translational magnetic tweezers for quantitative measurements at cellular and sub-cellular level. In the cellular studies, multiple membrane tethers were extracted simultaneously under constant force transduced ...
Examination of exogenous estrogenic chemical exposure and altered fetal nutrition in the CD-1 mouse fetus
(University of Missouri--Columbia, 2009)
My dissertation examines two issues related to disruption of fetal growth: exposure to exogenous estrogenic chemicals and altered nutrition. My first set of studies was aimed at manipulating isoflavones in feed on serum ...
Regulation of plant development in Arabidopsis
(University of Missouri--Columbia, 2008)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] The development of a complex organism, such as a plant, requires the function of multiple pathways that regulate various aspects of the developmental ...
Genome-wide exploration of direct GBX2 target genes and their contributions to mouse development
(University of Missouri--Columbia, 2013)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] The cells that comprise the vertebrate nervous system require molecular cues to determine their cellular position, identity and their ability to make ...
Developmental programming by xenoestrogens
(University of Missouri--Columbia, 2011)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Xenoestrogens (XE) are chemicals in the environment that mimic the body's natural steroidal estrogens. Developmental exposure to XE may interfere with ...
