Methodological approaches for sound training in underepresented learners: a case study with american toads (Anaxyrus americanus)
(University of Missouri--Columbia, 2021)
efforts to better understand the minds of animals have been flourishing, with methodological breakthroughs and a remarkable increase in the number of publications dealing with a wide variety of non-model species. The growing ...
Assessment of the microbiome associated with endangered orchids
(University of Missouri--Columbia, 2018)
The Orchidaceae (orchid family) is perhaps the most speciose group of flowering plants with approximately 25,000 described species and many thousands of hybrids. While certain mycorrhizal fungi are required for orchids to germinate...
Brassicales to Brassica : integrating phylogenomics and population genomics
(University of Missouri--Columbia, 2020)
to this diverse order. The focus of my dissertation has been to use phylogenomics and population genomics to understand the evolution of the Brassicales, as well as the important crop species Brassica oleracea. Within the Brassicales, the family Brassicaceae...
Uncovering the genetic basis of seed amino acid composition in arabidopsis using a multi-omics integrative approach
(University of Missouri--Columbia, 2021)
Seeds are a vital source of protein in the diet of humans and livestock. However, protein composition in the seed is low, comprising about 10 percent of the total composition in the seed. Additionally, protein quality in the seed is poor due to low...
The molecular underpinnings of neuronal cell identity in the stomatogastric ganglion of cancer borealis
(University of Missouri--Columbia, 2019)
Throughout the life of an organism, the nervous system must be able to balance changing in response to environmental stimuli with the need to produce reliable, repeatable activity patterns to create stereotyped behaviors. ...
The power of synteny : deep evolutionary insights from comparative genomics
(University of Missouri--Columbia, 2021)
tree-species tree incongruence. In Chapter III, as published in Abrahams et al., 2020, I utilize a microsynteny network and phylogenetic inference to investigate the origin and diversification of the MAM/IPMS gene family. I uncover unique MAM-like genes...
Assessing the effects of anticoagulant rodenticides on non-target fish species
(University of Missouri--Columbia, 2018)
voiced by the public. To determine AR effects on coral reef fish found in Hawaii, U.S. Geological Survey was asked to address their sensitivity as a prerequisite of another DPN aerial broadcast over Lehua Island. In December 2016, we presented our...
From unique killers to a jumbo genome - isolation and characterization of phages that infect the plant pathogen, Agrobacterium tumefaciens
(University of Missouri--Columbia, 2019)
cell growth and blocks cell division in a broad range of bacteria including Agrobacterium, Sinorhizobium, and Escherichia strains. Another member of the Podoviridae family, Atu_ph08, carries remnants of a lysogen and shares 60.2% identity...
Weed versus wildflower : mating system ecology in a taraxacum native-exotic contact zone
(University of Missouri--Columbia, 2020)
Closely related plant species often exhibit differences in ploidy level, mode of reproduction, and traits related to reproduction. Differences in ploidy levels are often associated with mating system differentiation, ...
Characterizing territoriality and the mechanisms that mediate it in female Anolis gundlachi lizards
(University of Missouri--Columbia, 2019)
Territoriality is a suite of behaviors through which animals secure access to particular areas or resources. It is prevalent across animal groups and has the potential to exert substantial influence on fitness by mediating ...
The evolution of complex calls In meadow Katydids
(University of Missouri--Columbia, 2018)
Meadow Katydids (genera Orchelimum and Conocephalus) are a specious group often are found in habitats with several species within the group living in sympatry. They produce complex calls with two distinct phrases, "buzzing" ...
Development of an amenable system for site-specific addition to a maize chromosome
(University of Missouri--Columbia, 2019)
Currently, transgenic maize is produced by random integration of a transgenes into the plant. This works for single genes, but not as well for multiple traits. Identifying plants that contain several transgenes becomes a ...
The effects of metal contamination on larval white sturgeon in the upper Columbia River
(University of Missouri--Columbia, 2018)
Sturgeon populations are imperiled worldwide. Declines are attributed to many factors including habitat degradation and alteration, overexploitation, and contamination. In North America, white sturgeon (Acipenser transmontanus) ...
Mechanisms of polar growth in the alphaproteobacterial order rhizobiales
(University of Missouri--Columbia, 2019)
All bacteria elongate and divide to faithfully reproduce their cell shape. Understanding the mechanisms that drive bacterial morphology requires an intimate knowledge of how the cell wall is synthesized. During cell ...
Establishing a foundation for large DNA transfer to artificial minichromosomes and B insert platforms in maize
(University of Missouri--Columbia, 2019)
In plants, conventional genetic engineering methods limit the number of available traits that could potentially improve the quality of agriculture. Agrobacterium-mediated transformation and biolistic bombardment are tools ...
Impact of selective motor neuron death on hypoglossal motor neuron survival and tongue morphology in a novel model of dysphagia
(University of Missouri--Columbia, 2019)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Amyotrophic lateral sclerosis (ALS) is a devastating disease characterized by the progressive loss of motor neurons and paralysis of the muscles they ...
