This thesis builds on previous research on geographic generic terms borrowed by the English language in Canada and the United States. It aims to fill a gap in the knowledge about the number of Spanish generic terms borrowed by English in the United States of America and the areas where these...

Absorption of UV light by nucleic acids can result in the formation of molecular lesions leading to mutagenesis, carcinogenesis, and cell death. Thus, understanding DNA damage is important for elucidating the molecular mechanisms of disease. Much effort has been focused on developing methods for...

Speciation and hybridization in the Old World swallowtail butterfly (Papilio machaon) species complex
DownloadSpring 2016
Species delimitation is fundamental to evolutionary biology. However the process is far from straightforward in systems with complex evolutionary histories, and the concept of species as taxonomic hypotheses is often overlooked in many biological disciplines. Here I investigate species...

Species delimitation in the Choristoneura fumiferana species complex (Lepidoptera: Tortricidae)
DownloadFall 2010
Species identifications have been historically difficult in the economically important spruce budworm (Choristoneura fumiferana) pest complex. Morphological, ecological, behavioural, and genetic characters have been studied to try to understand the taxonomy of this group, but diagnostic character...

Temporal isolation contributes to ecological speciation in a diversity of insect taxa. Such prezygotic isolation can reduce or stop hybridization between closely related taxa or populations, leading to speciation. Within the spruce budworm (Choristoneura fumiferana) species complex, hybridization...
