A molecular assessment of range expansion of the northern or virile crayfish (Orconectes virilis), crayfish-based community co-structure, and phylogeny of crayfish-affiliated symbionts
DownloadFall 2012
Geographical limits of a species’ range are determined in part by the environmental tolerances of that species, and also by its past and current ability to colonize new areas. Range shifts are a common occurrence in the evolutionary history of almost all taxa; however, anthropogenically-mediated...

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...

Masters thesis. Qualitatively and quantitatively documents the agonistic behaviour of captive male brown lemmings. Lemmings used in the experiments were originally from Point Barrow and maintained since 1962 as a colony at the Arctic Research Center in College, Alaska. Shipments to the University...

Bare-bones Paleontology: An Examination of the Systematic Methods Used in Vertebrate Paleontology and their Congruence with Avian Ichnotaxonomy
DownloadSpring 2016
Data used in the systematic paleontology of extinct vertebrates is limited to what can be collected from detailed comparisons of preserved anatomy. This restricts vertebrate paleontologists to those characters preserved on osteological specimens. Furthermore, parataxonomies such as ichnotaxonomy...

Comparative Analysis of the Anatomy of the Myxinoidea and the Ancestry of Early Vertebrate Lineages
DownloadFall 2012
The question of whether a hagfish is a true vertebrate or not has profound implications about the ancestry of the clade. New anatomical evidence allows a test of their systematic position. With dissections and serial sections of original specimens, and with a literature review, a comparative...

Contribution of glutaminase activity in Lactobacillus reuteri to acid resistance and glutamine metabolism in sourdough
DownloadFall 2016
Sourdough is used as an additive in bread production for proper dough volume (leavening), or for desired dough acidity, or for dough texture and bread flavor improvement, or for bread shelf life extension. Lactobacillus reuteri, an intestinal isolate and a stable member of sourdough, prevails in...

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...

Factors contributing to the competitiveness of Lactobacillus reuteri in sourdough and rodent gut
DownloadFall 2011
Lactobacillus reuteri is a common organism in cereal-based foods and a gut symbiont in humans and animals, yet the molecular mechanisms allowing its persistence in various niches are not well understood. L. reuteri LTH2584 produces reutericyclin and persists in industrial sourdoughs, where acidic...
