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...

Analyzing taphonomic deformation of ankylosaur skulls using retrodeformation and finite element analysis
Download2012
Taphonomic deformation can make the interpretation of vertebrate fossil morphology difficult. The effects of taphonomic deformation are investigated in two ankylosaurid dinosaur taxa, Euoplocephalus tutus (to investigate effects on our understanding of intraspecific variation) and Minotaurasaurus...

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...

Jiang, Tao, Lin, Guohui, Chen, Zhi-Zhong
Technical report TR03-06. Given a set of species and their similarity data, an important problem in evolutionary biology is how to reconstruct a phylogeny (also called evolutionary tree) so that species are close in the phylogeny if and only if they have high similarity. Assume that the...

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...

Evidence of euxinia in the Norian of western Canada: Implications to halobiid and monotid paleoecology and the sedimentology of the Pardonet formation
DownloadSpring 2024
The Norian Pardonet formation tops a well-studied Triassic stratigraphy in Western Canada which can be viewed in outcrop along the shores of Williston Lake, B. C. The Pardonet itself, however, has remained rather enigmatic. The formation is composed of dominantly finegrained, organic-rich...
