DHR51 as a coordinator of heme biosynthesis and steroid hormone production to time metamorphosis in Drosophila melanogaster
DownloadFall 2019
Development from a juvenile to an adult animal is driven by pulses of steroid hormones released at precise developmental times. Inputs from the environment, timing cues, and nutritional factors are all coordinated to produce a steroid hormone pulse. Insects and in particular, the fruit fly...

Aquatic nanotoxicity testing: Insights at the biochemical, cellular, and whole animal levels
DownloadFall 2013
Aquatic organisms are susceptible to waterborne nanoparticles and there is only limited understanding of the mechanisms by which these emerging contaminants affect biological processes. The unique properties of nanomaterials necessitate evaluation of standard toxicity testing techniques to...

Conserving cougars in a rural landscape: habitat requirements and local tolerance in west-central Alberta
DownloadSpring 2011
Maintaining large carnivores in human-dominated landscapes poses a significant conservation challenge. Extirpation is common because of habitat loss or direct persecution. I studied cougar habitat selection and human perception of cougars in west-central Alberta to better understand...

Axial patterning of the developing vertebrate eye is crucial for proper axon pathfinding, as well as critically important morphogenetic events such as closure of the ocular fissure. Perturbations in eye morphogenesis can lead to ocular coloboma (failed ocular fissure closure) and microphthalmia...

The roles of Pbx and Meis TALE-class homeodomain transcription factors in vertebrate neural patterning
DownloadFall 2010
One of the major goals of developmental biology is to understand how specialized groups of cells arise from an initially unspecified cell population. The vertebrate hindbrain is transiently segmented along its anterior-posterior axis into lineage-restricted compartments called rhombomeres, making...

Early mammalian development cannot progress without targeted temporal and spatial expression of genes. Changing the accessibility of DNA to transcriptional machinery is one critical way gene expression is controlled. This process, known as chromatin remodeling, is vital for formation of the...

Cleomaceae is an ideal system in which to investigate evolutionary transitions between monosymmetric flowers from polysymmetric ancestors. Previous studies have not produced a resolved phylogeny or explored the role of the candidate gene, TCP1, in the evolution of monosymmetric flowers. Here, I...

Development, Anatomy, and Phylogenetic Relationships of Jawless Vertebrates and Tests of Hypotheses about Early Vertebrate Evolution
DownloadSpring 2018
The origin and early evolution of vertebrates remain one of the central questions of comparative biology. This clade, which features a breathtaking diversity of complex forms, has generated profound, unresolved questions, including: How are major lineages of vertebrates related to one another?...

Calcium/calmodulin dependent protein kinase 2 (CaMKII) is a multifunctional serine/threonine kinase that is highly abundant in the central nervous system. It plays important roles in many neuronal functions, including neurite extension and maturation, activity-dependent synaptic plasticity and...

ABSTRACT The plant vascular system transports water and nutrients, but also regulatory molecules that function in short- and long-distance mechanisms to pattern surrounding tissues. As such, the development of the vascular system is tied to the overall patterning and development of the plant...
