Genomic analysis of hybridization between the spruce budworm species Choristoneura fumiferana, C. occidentalis, and C. biennis (Lepidoptera: Tortricidae)
DownloadFall 2014
The spruce budworm (Choristoneura fumiferana) species complex is a destructive group of insect defoliators of North American conifers that have a remarkable propensity to hybridize ex situ despite little evidence for hybridization in nature. Introgression between species is increasingly...

Spring 2014
The worldwide biodiversity crisis has intensified the need to better understand how biodiversity and human disturbance are related. Yet this relationship lacks both consensus in theoretical expectations and consistency in observed empirical patterns. I present one of the largest extent studies...

Identification and Exploitation of Oligosaccharyltransferase Dependent Bacterial Glycosylation Systems
DownloadFall 2014
Protein glycosylation, the covalent attachment of carbohydrates to amino acids, was once thought to be a unique attribute of Eukaryotes and select bacteria. However, both N- (attached to asparagine) and O- (attached to serine or threonine) glycosylation systems have been identified in an ever...

Insights from Sponge Transcriptomes & Physiology about the Early Evolution of Nervous Systems
DownloadFall 2014
The origin of neurons and neural systems is a research area that has begun to experience increased progress with the growing availability of genomic data from a range of basal metazoans and closely related outgroups. This has allowed a reevaluation of previous models of neural evolution....

Insights into temperature adaptation in the Thermotogae gained through transcriptomics and comparative genomics
DownloadFall 2014
Thermophilic microbes are extremophiles that live at high temperatures. In order to survive and maintain function of their biological molecules, they have a suite of characteristics not found in organisms that grow at moderate temperatures (mesophiles) that range from the cellular to the protein...

Fall 2014
The growth and development of an organ is a multi-step process. It involves initial specification of the progenitor cells to become a particular cell type, proliferation of those cells for organ growth, and organization of the cells into a final functional tissue. The growth and development of...

Fall 2014
Multiple carnivore species can have greater population limiting effects than single carnivores. Two coexisting carnivores can only be similar up to a certain extent. I investigate how two carnivores, wolves (Canis lupus) and cougars (Puma concolor), coexist through niche partitioning in the...

Local and regional demography in a migratory forest songbird and effects of forest management intensity
DownloadSpring 2014
The numerical response of forest birds to habitat alteration has been well documented in North America, but the underlying demographic processes driving these changes remain largely unknown. Among species sensitive to such alterations, the Ovenbird (Seiurus aurocapilla) shows one of the largest...

New insights about barnacle reproduction: Spermcast mating, aerial copulation and population genetic consequences
DownloadSpring 2014
Barnacles are mostly hermaphroditic and they are believed to mate via copulation or, in a few species, by self-fertilization. However, isolated individuals of two species that are thought not to self-fertilize, Pollicipes polymerus and Balanus glandula, nonetheless carried fertilized...
