The characterization of the tetratricopeptide repeat protein 13 in mammals
(University of Missouri--Columbia, 2012)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Tetratricopeptide repeat domain protein 13 (TTC13) is a member of a large family of proteins known as tetratricopeptide repeat (TPR) proteins that has ... -
Effects of spatial subsidies and canopy cover on pond communities and multiple life stages in amphibians
(University of Missouri--Columbia, 2012)Spatial subsidies are resources that move from one ecosystem to another. In aquatic systems, canopy cover determines both light availability and subsidy input in the form of senescing leaves. This phenomenon has been well ... -
The evolution of Brassica crops and wild relatives: phylogenetics, development and domestication
(University of Missouri--Columbia, 2012)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] The main goal of my dissertation is to understand the patterns and mechanisms underlying mustard (tribe Brassiceae, Brassicaceae) speciation in the ... -
Initial juvenile movement of pond-breeding amphibians in altered forest habitat
(University of Missouri--Columbia, 2012)The initial juvenile movement phase represents the first stage of the multi-phase process of natal dispersal. My objective was to investigate how alterations in forest habitat quality impact initial juvenile movement success ... -
An investigation of maize B chromosome-derived minichromosomes
(University of Missouri--Columbia, 2012)The maize (Zea mays) B chromosome is a supernumerary chromosome with a selfish inheritance characterized by nondisjunction at the second pollen mitosis, univalent survival in meiosis, and preferential fertilization of the ... -
Localization of the Rf3 restorer-of-fertility gene for maize S-type cytoplasmic male sterility
(University of Missouri--Columbia, 2012)Maize S-type cytoplasmic male sterility (CMS-S) is a maternally inherited trait that prevents pollen grains from developing to maturity. CMS-S is associated with the high levels of a novel mitochondrial transcript, ... -
Molecular mechanisms of radial axonal growth : insights from analysis of neurofilament gene-targeted mice
(University of Missouri--Columbia, 2012)For the nervous system to send signals rapidly, axons must undergo growth that expands their diameter. This process is known as radial growth and is dependent upon insulating myelin that wraps around the axon and the ... -
Neuromodulation-dependent regulation of coordinated patterns of gene expression in motor neurons of the stomatogastric ganglion
(University of Missouri--Columbia, 2012)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] The pyloric network of the crustacean stomatogastric ganglion (STG) is a central pattern generator that requires descending modulation for normal ongoing ... -
Phylogenomics of ancient whole genome duplications in the Brassicales
(University of Missouri--Columbia, 2011)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Ancient whole genome duplications (WGDs), which multiply copies of the entire genome within an organism, are ubiquitous throughout the evolutionary ... -
The secret lives of African forest elephants: using genetics, networks, and telemetry to understand sociality
(University of Missouri--Columbia, 2012)Knowledge of social structure is important to understanding the overall evolution and behavioral ecology of a species as it ultimately influences spatial patterns and gene flow. This dissertation focuses on the social ...
