Due to their abundance and ability to invade diverse environments, many arthropods have become pests of economic and health concern, especially in urban areas. Transcriptomic analyses of arthropod ovaries have provided insight into life history variation and fecundity, yet there are few studies in spiders despite their diversity within arthropods. Here, we generated a de novo ovarian transcriptome from 10 individuals of the western black widow spider (Latrodectus hesperus), a human health pest of high abundance in urban areas, to conduct comparative ovarian transcriptomic analyses. Biological processes enriched for metabolism—specifically purine, and thiamine metabolic pathways linked to oocyte …
Interspecific Gene Flow Potentiates Adaptive Evolution In A Hybrid Zone Formed Between Pinus Strobiformis And Pinus Flexilis, Mitra Menon
Theses and Dissertations
Species range margins are often characterised by high degrees of habitat fragmentation resulting in low genetic diversity and higher gene flow from populations at the core of the species range. Interspecific gene flow from a closely related species with abutting range margins can increase standing genetic diversity and generate novel allelic combinations thereby alleviating limits to adaptive evolution in range margin populations. Hybridization driven interspecific gene flow has played a key role in the demographic history of several conifer due to their life history characteristics such as weak crossability barriers and long generation times. Nevertheless, demonstrating whether introgression is adaptive …

Alcohol use disorder (AUD) is a debilitating psychiatric illness that develops from a combination of genetic and environmental factors. While it is well documented that AUD is heritable, the shift from recreational alcohol use to abuse/dependence is poorly understood. In this dissertation, using postmortem brain tissue from individuals with alcohol dependence (AD), we profiled the genome-wide expression of circular RNA (circRNA), microRNA (miRNA), and messenger RNA (mRNA) to better understand the impact of gene expression on the development of AUD. To achieve this, we performed two independent studies that explore transcriptome differences between AD cases and controls. The first of …
