Fall 2019
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...

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...

Characterizing the role of the endocannabinoid system’s catabolic enzymes FAAH and MAGL in the development of functional sensorimotor activities in zebrafish
DownloadFall 2022
The endocannabinoid system (eCS) plays a critical role in a variety of homeostatic and developmental processes. Generally, the eCS relies on the naturally produced compounds known as endocannabinoids (eCBs), which are lipophilic signaling molecules that interact with cannabinoid receptors 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...

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...

Description of new species of Osteostraci from the Man On The Hill locality, Northwest Territories, Canada, with consideration of the phylogenetic and biogeographic significance of the new taxa
DownloadFall 2011
The Lochkovian (Lower Devonian) Man on the Hill (MOTH ) locality, Northwest Territories, Canada, is a Konservat-Lagerstätte, where articulated early vertebrate remains are found. Among the early vertebrates preserved at the MOTH locality are the Osteostraci. Many specimens of osteostracan have...

Development and Evolution of Complex Reproductive Traits in the Brassicaceae and Cleomaceae
DownloadSpring 2023
Flowering plants exhibit a bewildering diversity of forms, which raises fundamental questions on how that diversity arises. A cornerstone of evolutionary developmental biology is the expansion of comparative landscapes and establishment of focal clades that enable investigation of complex and...

Development of the Voltage-Gated Sodium and Potassium Currents Underlying Excitability in Zebrafish Skeletal Muscle
DownloadFall 2009
Excitable cells display dynamically regulated changes in the properties of ion currents during development. These changes are crucial for the proper maturation of cellular excitability, and therefore have the potential to affect more sophisticated functions, including neural circuits, movements,...

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?...

Early late Paleocene mammals from the Roche Percée local fauna, southeastern Saskatchewan, Canada
DownloadFall 2009
The occurrence of vertebrate fossils from the Ravenscrag Formation near Roche Percée, southeastern Saskatchewan, Canada, documents the presence of a large and diverse assemblage of early late Paleocene (approximately 58 million years) mammals. Previous studies of the Roche Percée localities have...
