Phylogenomics and Evolution of Ground Beetles, with an Emphasis on the Speciose Tribes Chlaeniini and Bembidiini (Coleoptera: Carabidae)

Creator:: Pflug, James M.
Abstract:: In this dissertation, I investigate the evolution and genomes of carabid beetles, a worldwide family of over 38,000 species. I focus on two species-rich groups, the tribes Chlaeniini and Bembidiini, both of which are primarily found on the shores of bodies of water. The former are distinctive for their defensive...

The evolutionary stability of partial migration

Creator:: Ohms, Haley A.
Abstract:: Natural selection, in its most basic form, is described as a process in which traitsincrease or decrease in frequency depending on their fitness, and only the trait withthe highest fitness will remain in the population. Yet, populations rarely have asingle `optimal' trait. The way natural selection maintains this observed variationwithin...

Diversity and Evolution of Sexual Traits in Ground Beetles (Family Carabidae)

Creator:: Gomez, R. Antonio
Abstract:: Biologists have long been fascinated with reproductive traits, in part because they are frequently exaggerated or showy, and they commonly vary among closely related species. Exaggerated sexual traits, in particular, have been the focus of intense empirical and theoretical research, but most of this work has focused on traits involved...

Delimiting Species in the Mountaintops : New Trails for Studying Genomic Architecture and Sequencing Historical Specimens Uncover Hidden Diversity within the breve Species Group of Bembidion (Coleoptera : Carabidae)

Creator:: Sproul, John S.
Abstract:: Species are one of the foundational units upon which entire fields of scientific inquiry are built. Discovering and documenting the planet’s biodiversity remains one of the grand challenges of science. A proper conceptualization of species provides a critical framework for diverse fields such as biophysics, biochemistry, agriculture and pharmacology, and...

Phylogenetic Studies in Tenebrionidae (Coleoptera) and Related Families

Creator:: Kanda, Kojun
Abstract:: In this dissertation, I present the results from three studies: (1) a phylogeny of Tenebrionoidea (Coleoptera) inferred from a seven-gene dataset derived from PCR and Sanger sequencing; (2) a phylogeny of Tenebrionidae, the largest family in Tenebrionoidea, inferred from a four-gene dataset also derived from PCR and Sanger sequencing; (3)...

Explorations Into Who is Doing Freshwater Science and How We are Altering Waterscapes

Creator:: Abernethy, Erin F.
Abstract:: The United States of America and the world are faced with three massive intertwining challenges at this time: COVID-19, racial inequity, and climate change. As a species, humans must come together and collectively address these challenges to preserve our humanity and make our world a more just and livable place...

Linking Space, Time, and Elevation through Diet: Stable Isotope Analysis of Functionally Diverse Rodents in the Great Basin

Creator:: Taylor, David S.
Abstract:: Ecology is focused on understanding how organisms interact with each other and their environments, across ecological, spatial, and temporal scales. Thus, understanding how processes and patterns of ecological systems change across space and time is a principle goal for conservation biologist globally. While many approaches exist for investigating the changing...

Life in a Rapidly Changing Environment: The Thermal Biology of the Red-sided Garter Snake (Thamnophis sirtalis parietalis)

Creator:: Hubert, David L.
Abstract:: At a time when environmental conditions are rapidly changing, understanding how thermal extremes impact wildlife is imperative to fully understanding the consequences of climate change in natural ecosystems. While many organisms are currently impacted by rapidly warming and more erratic environmental conditions, identifying and investigating model species whose life histories...

Effects of Diversity on Emerging Infectious Diseases of Amphibians

Creator:: Snyder, Paul W.
Abstract:: Species declines and extinctions have been recorded across taxa as evidence of an ongoing global biodiversity crisis. Amphibians are at the forefront of these declines with nearly one third of amphibian species estimated to be at risk of extinction. While many factors contribute to population declines and extinctions, the role...

Trade-offs in a pathogen-rich world : genetic and maternal drivers of variation in costly resistance and immunity in African buffalo (Syncerus caffer)

Creator:: Tavalire, Hannah F.
Abstract:: Disease acts as a powerful selective force in natural systems, driving the rapid evolution of resistance in the host. In the face of a myriad of pathogenic challenges in natural systems, hosts must balance the energetic needs of maintenance and reproduction with costly resistance mechanisms. In this dissertation I will...
