Genomic And Phenotypic Insights Into The Mechanisms Of Adaptation In High-Elevation Deer Mice, Keely R. Corder

Graduate Student Theses, Dissertations, & Professional Papers

The study of adaptation to extreme environments offers a lens to explore the fundamental processes of evolution. Organisms living in challenging conditions, such as high elevation, must evolve a suite of physiological and genetic adaptations to survive and thrive. However, our understanding of the mechanisms underlying such adaptations and the processes driving their evolution remains incomplete. This dissertation aims to expand our knowledge of adaptive evolution in extreme environments by integrating genomic, phenotypic, and demographic data in the North American deer mouse (Peromyscus maniculatus), a model system for high-altitude adaptation. The dissertation addresses three main gaps in knowledge: (1) the …

Flower Bases In Full Bloom: Intersecting Families And A Generalization Of Diversity, Ryan Wood

Graduate Student Theses, Dissertations, & Professional Papers

In this work, we present results employing the flower base method. We work in the field of extremal set theory, focusing our attention on r-uniform intersecting families. The classic Erd˝os-Ko-Rado Theorem states that, for n large enough, the largest runiform intersecting family, a so-called maximum star, consists of taking all r-sets containing a fixed element. Lemons and Palmer [31] investigated the diversity function, showing that the largest intersecting family that is the most “un-star-like” consists of taking all r-sets containing at least two members of a set of size three. Our main problem, that of C-weighted diversity, unifies these two …

Drivers And Fates Of Primary Production In A Dammed, Eutrophic River, Laurel Genzoli

Graduate Student Theses, Dissertations, & Professional Papers

Algae, cyanobacteria, and aquatic plants are essential components of river ecosystems, providing the basis for aquatic food webs, determining water quality, and controlling carbon and nutrient cycling in rivers. Despite their importance to river ecosystems, growth and accumulation of river photoautotrophs beyond historic levels cause ecological and social harm. The drivers of riverine primary production are poorly understood relative to algae blooms in lakes due to a paucity of studies in rivers, challenges with quantifying periphyton, and interacting and co-varying controls associated with river flows. In my dissertation, I quantified photoautotrophs and aquatic primary productivity in a dammed, eutrophic river …

Brat Olympics, Caroline Ganci Patterson

Graduate Student Theses, Dissertations, & Professional Papers

brat olympics is an exploration of feminine disgust, apprehension, and disorientation contextualized through interpersonal relationships and societal shapeshifting. It pays particular attention to gender performance, surburban queerness, and strangerness. The manuscript plays on the history of the bildungsroman, but instead of one consistent singular timeline, it provides three separate attempts at a characterization of a life. These disparate approaches to a singular life’s characterization stress the mundanity of documentation.

This multinarrative approach satirizes the ideal of the singular confessional, and presents a discursive approach to the way we choose to build our worlds. Building off the works of the New …

Identifying And Predicting Patterns Of Snowpack Ripening With Machine Learning Methods, Clement Cherblanc

Graduate Student Theses, Dissertations, & Professional Papers

The timing of water release from the snowpack plays key roles in ecosystem services, groundwater recharge, and water resource management. However, two internal barriers in a standing snowpack must be overcome before runoff can outflow from the base: 1) the cold content must be exhausted, and 2) the interconnected network of snow grains must be filled with liquid water to residual saturation. Expressing the liquid water as latent heat allows the two barriers to be grouped as an energy (J/m²) to define a snowpack’s Runoff Energy Hurdle (REH). The growth and loss of REH is driven by evolution of pore …

Graduate Student Theses, Dissertations, & Professional Papers

In this dissertation, I aim to (i) advance the understanding of pronghorn ecology and population responses to environmental variability, and (ii) test analytical tools linking environmental habitat factors to demographic processes. In doing so, I answer the following questions: How should we expect pronghorn demographic rates to vary from year to year? How do environmental conditions influence pronghorn survival? How do long-term impacts from environmental conditions directly affect pronghorn demographic trends like survival or abundance? Do environmental conditions influence pronghorn density and distribution in the same way? If not, how do they differ? Finally, in an increasingly changing landscape, what …

“I Still Live!” Daniel Webster And The Politics Of Commemoration In The Age Of Disunion, Michael James Larmann

Graduate Student Theses, Dissertations, & Professional Papers

This dissertation explores the political afterlife of American statesman Daniel Webster (1782- 1852) from 1852 to 1865. It explores two distinct yet interconnected theaters of politics in antebellum America: the politics of memory and the politics of commemoration. Webster’s followers engaged in the politics of memory by resurrecting their statesman in the national arena. Defenders, detractors, and partisans contested Webster’s memory to claim power and legitimacy during the sectional crisis in the 1850s and during the Civil War in the 1860s.

The physical monument in Boston was the epicenter for a second political theater, the politics of commemoration. Following the …
