Spring 2016
Mosasauridae is a lineage of extinct marine squamates that inhabited the world’s oceans during the Late Cretaceous (100-66 Ma). The name Mosasaurus was given to the first described specimen, which was a fossil discovered in Maastricht, the Netherlands, during the 1770s. Naturalists of the time...

Boxed-in: Comparing Algorithms for Box-flight Mass-Balance Greenhouse Gas Flux Measurements from Mineable and In Situ Oil Sands Developments
DownloadSpring 2022
To combat global warming, Canada has committed to reducing greenhouse gases (GHGs) 40-45% below 2005 emission levels by 2025. Monitoring emissions and deriving accurate inventories are essential to reaching these goals. GHGs can be measured at a small scale, often using ground measurements which...

Cranial Morphology, Taxonomy, and Systematics of Pachycephalosaurids (Dinosauria, Ornithischia)
DownloadSpring 2022
Pachycephalosauridae (pachcycephalosaurids) were small to medium sized bipedal ornithischians, known solely from the Late Cretaceous of North America and Asia. These dinosaurs are characterised by thick, often domed frontals and parietals (frontoparietal dome), which are thought to have been used...

Diversity of wetland non-biting midges (Diptera: Chironomidae) and their responses to environmental factors in Alberta
DownloadSpring 2016
Wetlands provide a wide range of services, including improving water quality, providing habitats for wildlife, and storing floodwaters. In Alberta, wetlands cover about 21% of the landscape of the province. In Alberta, as elsewhere, wetlands have suffered from human activities and many have...

Molecular characterization of Tubifex populations in Alberta, Canada, and their role in the spread of whirling disease
DownloadSpring 2024
Whirling disease is a parasitic infection caused by Myxobolus cerebralis Hofer (Cnidaria: Myxozoa) and is debilitating to the salmonid fish that act as hosts. As of 2016, this parasite has been confirmed in Alberta, Canada. This thesis focused on estimating how long M. cerebralis has been present...

Spring 2020
I argue that in order to resolve the debate between taxonomic monism and taxonomic pluralism, we should construe the reality of natural kinds in terms of relative fundamentality: a natural kind is real if and only if it is more fundamental than its members, whose reality is taken for granted in...

Fall 2023
This thesis examines Charles R. Knight’s images of dinosaurs produced around the turn of the nineteenth century in comparison to natural history images of living animals. Using a combination of scholarship from animal studies and an analysis of the side of production, it argues Knight used visual...

Soil Mesostigmata (Arachnida: Parasitiformes) in boreal forests of Alberta: diversity and utility as indicators of disturbance
DownloadSpring 2018
Soils provide numerous ecosystem services, including provision of nutrients for plants, sequestration of greenhouse gases, and serving as habitat for soil animals. Soil animal diversity is immense, and many undescribed taxa still remain. One prominent group that inhabits soils is mites...

Fall 2018
Benthic marine habitats in Canada have been well-sampled since the annual groundfish survey commenced in 1970. However, trawl surveys cover only non-rocky sediments and many species collected are not identified to lower taxa, leaving large gaps in our understanding of benthic diversity. Sponges...

Spring 2010
Many adult concepts can be represented in taxonomies – hierarchical systems in which concepts are differentiated into varying levels of abstraction (e.g., musical instrument, wind instrument, flute) related by class inclusion (a flute is a wind instrument and a wind instrument is a musical...
