Aggressive calling in treefrogs
(University of Missouri--Columbia, 2011)Acoustic communication plays a major role in many of the social activities of frogs. A great deal is known about communication in some contexts, such as mate choice. Aggressive communication, however, has received little ... -
Communication about predation risk between parents and offspring groups in treehoppers
(University of Missouri--Columbia, 2011)False alarms should be common and costly for group-living animals, but to limit false alarms, animals must evade a tradeoff between response sensitivity and accuracy. I investigated this topic in two closely-related species ... -
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 ... -
Immunogenic properties of neuralized embryonic stem cells in a model of allogenic intracranial transplantation
(University of Missouri--Columbia, 2011)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Intracranial stem cell transplantation has may restore central nervous system (CNS) function and compensate for neural cell loss. However, immunological ... -
Intrinsic, extrinsic and environmental regulation of muscle satellite cell motility
(University of Missouri--Columbia, 2011)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Skeletal muscle repair and regeneration requires the activity of satellite cells, a population of myogenic stem cells. Previously, little data existed ... -
Mitochondrial DNA insertions in the nuclear genomes of maize (Zea mays ssp. mays)
(University of Missouri--Columbia, 2011)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Mitochondria were derived from once free--living [alpha]-proteobacteria and became part of eukaryotic cells through endosymbiosis (Kleine et al. 2009). ... -
Phylogenetic and behavioral differentiation in the canyon treefrog, Hyla arenicolor
(University of Missouri--Columbia, 2011)My research interests lie in understanding the process of speciation. In my dissertation I set out to do this by examining the first step in potential speciation, population differentiation. In my dissertation research I ... -
Phylogenetic and phylogenomic studies of wild onions (Allium, Amaryllidaceae) at three taxonomic scales
(University of Missouri--Columbia, 2011)I used standard molecular phylogenetic and emerging phylogenomic methods to address questions about the evolutionary relationships among populations, species and subgeneric clades of the genus Allium. To test the hypothesis ... -
Postcopulatory sexual selection in the soldier fly Merosargus cingulatus
(University of Missouri--Columbia, 2011)My dissertation research focuses on the largely understudied field of postcopulatory (or "cryptic"') mate choice. As part of my dissertation research, I have developed a novel model system for the study of postcopulatory ... -
Social and psychobiological regulation of the human child's hypothalamus-pituitary-axis : an ontogenetic perspective
(University of Missouri--Columbia, 2011)On the basis of life history theory, the delayed reproductive maturity represented by an extended period of childhood and juvenility in humans is predicted to be important for learning cultural, social, and ecological ... -
Teratoma formation by neuralized C57BL/6J-EGFP mouse embyonic stem cells after syngeneic transplantation into the midbrain
(University of Missouri--Columbia, 2011)Embryonic stem (ES) cells can differentiate into many specialized cell types, including neural cells. Numerous induction protocols have been developed to direct their differentiation. Our lab created an in vitro neural ... -
A unique way to form a vesicle: aminopeptidase 1 aggregation and its binding to receptor ATG19 for recruitment of autophagic proteins to form a vesicle in the cytoplasm-to-vacuole-targeting pathway in yeast
(University of Missouri--Columbia, 2011)Misfolded protein aggregation causes disease and aging; autophagy counteracts this by eliminating damaged components, enabling cells to survive starvation. The Cytoplasm-to-vacuole-targeting (Cvt) pathway in yeast encompasses ...
