Effects of prescribed fire and timber harvest on terrestrial salamander abundance, behavior, and microhabitat use
(University of Missouri--Columbia, 2014)
The goal of my dissertation was to assess how terrestrial salamanders respond to two common forest management practices -- prescribed fire and timber harvest. Previous studies have reported that timber harvest adversely ...
Developing tools for making inferences from genomic data
(University of Missouri--Columbia, 2019)
The central question that the King lab seeks to answer is, "What happens on the genomic level when phenotypes evolve?" To this end, the core focus of my work has been on developing software and analytical methods that ...
Genetic diversity and distribution of the ringed salamander (ambystoma annulatum) across multiple spatial scales
(University of Missouri--Columbia, 2018)
lower gene flow for A. annulatum and A. opacum, two fall breeding species, as compared to two spring breeding species (A. maculatum and N. v. louisianensis) across the same focal landscape. Across all four species, I identified marginal support...
Exploring the diverse functions of peptidoglycan hydrolases in the plant pathogen, Agrobacterium tumefaciens
(University of Missouri--Columbia, 2019)
The plant pathogen Agrobacterium tumefaciens displays an atypical form of unipolar elongation, followed by incipient pole synthesis during cell division and cell separation. Currently, how polar growing bacteria modulate ...
Role of neuronal positioning in jaw motor circuit function in zebrafish
(University of Missouri--Columbia, 2021)
Development of the vertebrate nervous system involves substantial cell migration, where immature neurons move to specific locations to generate functional circuits. Precise neuronal migration and positioning are essential ...
Cellular behaviors regulating tangential migration of facial branchiomotor neurons in the zebrafish embryo
(University of Missouri--Columbia, 2009)
Development of the nervous system is characterized by intricate processes like neuronal migration, axon outgrowth and guidance and synaptic connections to their targets. These processes involve navigation of the migrating ...
The molecular underpinnings of neuronal cell identity in the stomatogastric ganglion of cancer borealis
(University of Missouri--Columbia, 2019)
and the cardiac ganglion, continue to provide important new insights into circuit dynamics and modulation (Diehl, White, Stein, & Nusbaum, 2013; Marder, 2012; Marder & Bucher, 2007; Williams et al., 2013), but this work has been partially hampered by the lack...
Approaches for unveiling the kinetic mechanisms of voltage gated ion channels in neurons
(University of Missouri--Columbia, 2019)
Ionic currents drive cellular function within all living cells to perform highly specific tasks. For excitable cells, such as muscle and neurons, voltage-gated ion channels have finely tuned kinetics that allow the ...
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 ...
Ecological genomics of divergence, admixture, and fitness in the smallmouth bass (Micropterus dolomieu)
(University of Missouri--Columbia, 2021)
The Smallmouth Bass (Micropterus dolomieu) is one of the most highly targeted sport fishes in the world. Anglers vie for the opportunity to catch Smallmouth Bass recreationally and competitively, spending billions of dollars ...
Motor neuron output in the crustacean cardiac ganglion is organized and maintained by homeostatic conductance relationships
(University of Missouri--Columbia, 2013)
Generating appropriate and functional neuronal output is a matter of fundamental importance to nervous systems across species and phyla. Potential perturbations to a neurons intrinsic excitability alone include Hebbian ...
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 ...
Assessing the effects of anticoagulant rodenticides on non-target fish species
(University of Missouri--Columbia, 2018)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Invasive rat species have negatively affected island ecosystems contributing to the decline and extinction of many endemic species. The eradication of ...
