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...

The Paleobiology, Paleoecology, and Evolution of Thescelosauridae (Ornithischia) from Alberta, Canada
DownloadFall 2021
Thescelosauridae is a basal neornithischian dinosaur clade that flourished in the Cretaceous from the Aptian to the Maastrichtian. This diverse but poorly studied group of small-bodied herbivores is divided taxonomically into Orodrominae and Thescelosaurinae, and existed in Asia and North and...

Dromaeosaurids were small to medium sized theropod dinosaurs that diversified during the Late Cretaceous, reaching a near cosmopolitan distribution. They were diverse in morphology from the small four-winged gliders of Microraptorinae, to the bear-sized giant ‘raptors’ like Achillobator or...

The Evolutionary Ecology of Parasitic Strategies: Experimental Evolution with a Facultatively Ectoparasitic Mite
DownloadSpring 2019
Although parasitism is a ubiquitous lifestyle, little empirical evidence exists for how and why parasitism evolves from free-living lineages. Analysis of phylogenetic relationships among taxa that exhibit a range of lifestyles has aided in the development of a commonly proposed hypothesis for the...

Cilia are microtubule-based structures that project from nearly every cell in the vertebrate body. While cilia in different contexts can have either sensory or motile functions, all cilia rely upon a core set of genes. When these genes are mutated either singly or in various combinations, a...

Here I describe new oviraptorosaur specimens and add to our knowledge of the anatomy, growth, behaviour, ecology, and evolution of oviraptorosaurs. Oviraptorosaurs were a diverse group of theropods known from a long history of discovery and a relatively abundant fossil record. Most analyses...

A full understanding of the evolution of novel forms requires inference about their origins through the study of variation in extant taxa and clues from the fossil record. However, the origins of morphological diversity in many groups are obscured by the scarcity of transitional fossils or...

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?...

Leafrollers moths are one of the most ecologically and economically important groups of herbivorous insects. These Lepidoptera are an ideal model for exploring the drivers that modulate the processes of diversification over time. This thesis analyzes the evolution of Choristoneura Lederer, a well...

Three species of Cretaceous marine squamates are described or redescribed. The first, Pontosaurus ribaguster is described from a relatively complete specimen discovered on Hvar Island, Croatia. Preservation of identifiable nektonic teleosts within the gastric cavity (the first identifiable...
