The abundance and diversity of stream salamanders on montane golf courses
(University of Missouri--Columbia, 2012)Stream salamanders are often the most abundant vertebrates in headwater streams and they play an integral role as both predators and prey in these ecosystems. Because they often use both terrestrial and aquatic habitat and ... -
The Agrobacterium tumefaciens min system contributes to the regulation of cell division
(University of Missouri--Columbia, 2016)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] In A. tumefaciens, the essential FtsZ protein is located at the growth pole before shifting to the mid-cell right before division. Recruitment of FtsZ ... -
Association of force plate and body-mounted inertial sensor measures for determination of hind limb lameness in horses
(University of Missouri--Columbia, 2015)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] The purpose of this study was to investigate the association between inertial sensor and stationary force plate measures of hind limb lameness. 21 ... -
Bat avoidance in the katydid genus Neoconocephalus
(University of Missouri--Columbia, 2010)The hearing system of the katydid genus Neoconocephalus has two functions: intraspecific communication and predator (bat) avoidance. Male calls and bat cries differ spectrally and temporally. Katydids must recognize and ... -
The biology of the Florida scrub endemic millipede: Floridobolus penneri
(University of Missouri--Columbia, 2006)Even though millipedes provide a number of important ecosystem services, the group overall is understudied and nowadays largely ignored in the USA. Most millipedes that are well-studied occur in temperate, mesic environments, ... -
Bisphenol A (BPA) in human serum and urine : exposure via dermal absorption from thermal paper receipts and oral ingestion after transfer from hand to food
(University of Missouri--Columbia, 2013)Bisphenol A (BPA) exposure is thought to be mainly due to absorption from the gut by oral ingestion. However thermal receipt paper represents another potential source of BPA exposure via direct absorption through the skin ... -
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 ... -
Characterization of the relationship between radiographic grading and biomarkers in patients with knee osteoarthritis
(University of Missouri--Columbia, 2020)"Osteoarthritis (OA) is a whole-joint degenerative disease, affecting more than 25% of the adult population. Currently, OA is most commonly diagnosed based on radiographic documentation. However, radiographic grading is ... -
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 ... -
Does history repeat itself? : Impact of climate on floral resources for bumble bees then and now
(University of Missouri--Columbia, 2014) -
Drivers of tree community composition and seed demography in Serengeti National Park - Tanzania
(University of Missouri--Columbia, 2015)Savannas are spatially diverse, variable and susceptible to high rates of disturbance from fire and herbivory. There is a significant amount of interest in woody species dynamics in relation to disturbance regimes but less ... -
Drug resistance in D. discoideum: isolation of 4-nitroquinoline 1-oxide resistant mutants
(University of Missouri--Columbia, 2005)The drug 4-nitroquinoline 1-oxide (4NQO) displays both carcinogenic and antitumor effects, a well known characteristic of many chemotherapeutic drugs. In addition 4NQO shares a similar operating mechanism with the commonly ... -
Effects and interactions of endocrine disrupting chemicals and diet on the mouse reproductive system
(University of Missouri--Columbia, 2007)Recent studies have indicated that a number of ubiquitous chemicals found in the environment are linked to a myriad of health concerns, including reproductive abnormalities and increases in infertility, cancer, and obesity ... -
The effects of axotomy on the biophysical properties of reticulospinal neurons in larval lamprey
(University of Missouri--Columbia, 2006)Following severe spinal cord injury (SCI), in adult higher vertebrates there is little or no axonal regeneration, and animals remain paralyzed below the lesion. In contrast, lower vertebrates such as the lamprey, following ... -
The effects of histone acetylation on the maize allele PL1-blotched
(University of Missouri--Columbia, 2007)Covalent modifications of DNA and nucleosomal histone proteins associated with eukaryotic chromatin have the potential to alter expression of a gene without change in its DNA sequence. One gene regulated through this ... -
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 ... -
Evolution and development of the paired spikelet trait in maize and other grasses (Poaceae)
(University of Missouri--Columbia, 2017)Meristems are composed of groups of tightly-regulated cells that coordinate the number of stem cells in the central zone of the meristem with the number of cells migrating to organ primordia in the peripheral zones of the ... -
Fetal exposure to low but not high doses of Bisphenol A (BPA) increases abdominal fat, impairs glucose tolerance and alters serum hormones in male mice : evidence for non-monotonic dose-response relationships
(University of Missouri--Columbia, 2012)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Bisphenol A (BPA) is a ubiquitous contaminant with estrogenic and other hormonal activities. A criticism of many experimental studies is the lack of ... -
Generating temperature sensitive inteins for studying gene functions
(University of Missouri--Columbia, 2008)Reversible and easy to use, temperature-sensitive (TS) mutations, are powerful tools to study the functions of all genes, including essential and pleiotropic ones. However, the rarity of TS alleles and the difficulty of ... -
Gray treefrog breeding site selection and offspring performance in response to forest management
(University of Missouri--Columbia, 2007)Amphibian diversity and abundance are generally reduced following clearcut logging. These impacts often last for decades, but little is known about why diversity and abundance are depressed. I examined gray treefrog breeding ...
