Why Do Caterpillars Whistle? Acoustic Mimicry Of Bird Alarm Calls In The Amorpha Juglandis Caterpillar, Jessica Lindsay

Undergraduate Theses, Professional Papers, and Capstone Artifacts

Caterpillar species possess a range of anti-predator defenses, from regurgitation to sonar jamming. The North American walnut sphinx caterpillar (Amorpha juglandis) produces a variety of whistling noises when pinched. Limited observations indicate that this causes avian predators to retreat, leaving the caterpillar alone. However, it is unknown why this whistle is such an effective deterrent. Interestingly, the A. juglandis whistle is acoustically similar to the “seet” alarm call that many bird species produce in response to their own predators. We propose that the A. juglandis whistle is a form of acoustic mimicry, in which the caterpillar protects itself …

Taphonomy Of The Chengjiang Biota: Using A Combination Of Sedimentology, Geochemistry And Experimental Taphonomy To Determine Preservation, Lindsay Ann Mackenzie

Graduate Student Theses, Dissertations, & Professional Papers

The Chengjiang Biota, found in the Early Cambrian Maotianshan Shale (Yunnan, China), represents the Cambrian ôexplosion of life,ö providing a snapshot of the early evolution and development of complex life. This snapshot is possible because high fidelity processes transfer information from living organisms to preserved fossils. Taphonomy is everything that occurred during this information transfer from death to fossilization and discovery, including chemical and/or sedimentological processes. The Chengjiang fossilsÆ biology is well documented and taphonomical processes have been proposed. Tests of these models are limited because the depositional environment remains poorly understood. To fill this gap and better constrain the …

The Biogeochemistry Of Elemental Sulfur Contaminated Soils: Insights Into Effective Remediation, Michael Ryan Mctee

Graduate Student Theses, Dissertations, & Professional Papers

Soil contamination that results from elemental sulfur (S⁰) deposition is a new occurrence. Elemental sulfur is stockpiled as a byproduct from the oil and gas industry and is deposited by biodegradable trap and skeet targets at shooting ranges. Chemolithotrophs and mixotrophs can oxidize S⁰ to H₂SO₄. Consequently, in areas where excess S⁰ is deposited or stockpiled, soils can acidify to pH values observed with acid mine drainage.

I studied S⁰ contamination at a former sporting clay range. For seven years, the range used biodegradable trap and skeet targets that contained S …

Snip, Snap, Snout: This Tale Is Told Out, Crista A. Ames

Graduate Student Theses, Dissertations, & Professional Papers

Mythology has shaped human thought and experience since before recorded history. Passed from one generation to the next, myths elevate and aggrandize realities that are difficult, complex or horrifying. This is what makes us human, an inspiring capacity toward metaphor and the ability to make beauty, lyricism and splendor—order from the chaos. Within mythology, the cause and effect of both misery and joy may be explored in their wholeness. In this act of imaginative translation, we may come to understand how misery and joy are naturally coexisting.

In my thesis exhibition this tale is told out, I use the layering …

Economic And Policy Factors Driving The Adoption Of Institutional Woody Biomass Heating Systems In The United States, Jesse D. Young

Graduate Student Theses, Dissertations, & Professional Papers

New biomass combustion technologies and adequate biomass supplies have empowered the United States (U.S.) to look beyond satisfying heating needs with traditional fossil-based fuels, but biomass heating is often overlooked by many commercial and institutional entities. This study uses county level Zero Inflated Negative Binomial (ZINB) cross sectional regression analyses to identify economic factors that are favorable to the adoption of decentralized woody biomass heating systems by institutions in the U.S. In addition, biomass policy efficacy with respect to decentralized biomass heating systems is analyzed and regression results are used to develop an expansion map that highlights counties in the …

An Adventurous E-Reader For Non-Linear E-Books, Emily Palmieri

Graduate Student Theses, Dissertations, & Professional Papers

Non-linear books are published in print format as sequential text or digitally as collections of documents linked together via hyperlinks. These publication methods are problematic for readers and authors alike. Readers are often presented with unintuitive interfaces that do not indicate critical contextual information; authors struggle to order non-linear content into linear formats or to create and distribute their work in resource intensive digital mediums. While standard e-books might be a convenient format for non-linear books, current e-readers used to view them are severely limited; they mimic the format of physical books and fail to solve problems inherent in displaying …

Characterization Of Pm2.5 From Residential Woodstove Use For Source Apportionment Application, Virginia M. Porden

Graduate Student Theses, Dissertations, & Professional Papers

Results are presented for the comparative analysis of the PM_2.5 (Particulate Matter <2.5 µm) emissions from an EPA certified and a Traditional style wood stove using western larch. A total of 92 Quartz QMA 47mm filters were collected using a BGI PM_2.5 SSC (Sharp Cut Cyclone) sampler from each stove type and analyzed on a gas chromatograph-mass spectrometer against blank and deuterated internal standards. The results were analyzed using a Welch’s t-test (α > 0.05) to statistically differentiate between stove designs for temperature, mass, levoglucosan, resin acids (abietic and dehydroabietic), and polycyclic aromatic hydrocarbons [PAH] (acenaphthene, anthracene, benz(a)anthracene, pyrene, and retene). There was no statistical difference in levoglucosan PM_2.5 mass fraction between the stove types, yielding a mean levoglucosan fraction of 9.25% and 95% confidence interval of 8.43% …

Assessing Changes In Avian Communities, Jessie D. Golding

Graduate Student Theses, Dissertations, & Professional Papers

Grazing is a potentially powerful tool to address wildlife declines associated with land use conversion in the western United States. Grazing systems can be manipulated to achieve desired vegetation outcomes, preserve native habitat and economically benefit multiple stakeholders. As a result, systems designed to benefit native ecosystems are being widely implemented. However, the benefits of these grazing systems on many wildlife communities remain relatively unexplored. Songbirds provide an ideal study system to test these benefits because they continue to use native habitat that is currently grazed. Given limited time and resources, conservation practitioners often monitor a single focal species or …

Estimation Of Historic Salmon Populations And Its Application To Contemporary Salmon Conservation, Nick Joseph Gayeski

Graduate Student Theses, Dissertations, & Professional Papers

Populations of wild Pacific salmon and steelhead (Oncorhynchus sp.) in the eastern Pacific Rim have experienced significant declines in abundance and associated genetic and life history diversity over the course of the twentieth century (Nehlson et al 1991, Slaney et al 1996, Myers et al 1998, Lichatowich 1999). In the Pacific Northwest of the United States, declines in the abundance of most populations accelerated in the last two decades of the century and have continued into the first two decades of the twenty-first (Busby et al 1996, Myers et al. 1998, Good et al.2005, Hard et al. 2007, Ford et …

Population Differentiation And Habitat Selection Of A Montane Red Fox Population In The Greater Yellowstone Ecosystem, Patrick Cross

Graduate Student Theses, Dissertations, & Professional Papers

Montane red fox (Vulpes vulpes) populations across the western United States are genetically and morphologically distinct from foxes at lower elevations. These montane populations also share a preference for subalpine forest habitats. One hypothesis is that they stem from boreal forest-associated ancestors that expanded during the Pleistocene when boreal forests extended farther south than they do today. Forest habitat selection may therefore aid the persistence of native populations surrounded by non-native conspecifics. Alternatively, this behavior may be an avoidance mechanism in response to competition with larger coyotes (Canis latrans), or a product of the fox's natural adaptability. The red fox …

The Piegan View Of The Natural World, 1880-1920, Rosalyn R. Lapier

Graduate Student Theses, Dissertations, & Professional Papers

This dissertation is a new interpretation of the stories told by the Piegan people (now known as the Blackfeet) from 1880-1920, about their relationship with the natural world. It is a history of the transition to reservation life, the economy of the reservation, individual Piegan who told stories, the ethnographers who recorded the stories and what those stories tell us about Piegan views of the natural world. It is a blend of different methodologies within history: archival research, ethnohistory, oral history and first-person narrative. This new interpretation argues that although the transition to reservation life was difficult, the Piegan worked …

The Bioscience-Industrial Complex, Radical Materialist Aesthetics, And Interspecies Political Ecologies: The Unforeseen Posthuman Future In Mary Shelley's Frankenstein And Margaret Atwood's Maddaddam Trilogy, Sarah Sydney Lane

Graduate Student Theses, Dissertations, & Professional Papers

This project traces how Mary Shelley’s Frankenstein and Margaret Atwood’s MaddAddam Trilogy, science fiction novels from the Romantic and contemporary literary periods respectively, contest the problematic relationships between subjecthood, science, ecological health, and patriarchal, capitalist societies by crafting radical materialist alternatives to such a system and its dualistic and destructive interpersonal/interspecies relations. Through the theoretical framework of ecofeminism that recognizes the conceptual linkages between women and nature in Western systems of thought, as well as psychoanalytical feminist critiques of the masculinization of scientific epistemology, this project examines the developmental and ontological overlaps between literary “masculine” and “scientific” subjects socialized under …

The Ethics Of Mourning: The Role Of Material Culture And Public Politics In The 'Book Of The Duchess' And The 'Pearl' Poem, Tarren Andrews

Graduate Student Theses, Dissertations, & Professional Papers

This project is a socio-historic analysis of two late 14^th century dream visions: Chaucer’s Book of the Duchess and the Pearl poem. Utilizing Robert Pogue Harrison’s concept of objectifying grief through ritualized communal mourning, this thesis examines the ways in which mourning literature functioned as consolatory device, and a form of public performance for the powerful patrons who commissioned the pieces. By engaging with pre-existing communities of grief, material culture, and courtly discourse these poems perform the work of mourning while simultaneously enacting modes of public performativity that stress the ethics of grieving, and suggest that, for royal patrons, …

Melville's Mardi And The Book Of Mormon, Giordano Lahaderne

Graduate Student Theses, Dissertations, & Professional Papers

While Melville’s Mardi has long remained a puzzle to both readers and critics, scholars agree that his third novel marked a significant turning point in his writing career. It is with Mardi that Meville realized the novel as a form suited to grapple the various philosophical and religious questions he would famously explore in his following book, Moby Dick. Although scholars have already pinpointed many various sources for Mardi, this thesis examines the heretofore overlooked connections between Melville’s third book and the esoteric volume of American scripture, the Book of Mormon.

The first chapter of this thesis examines …

Do Big Beetle Larvae Run Big Thermal Risks?, Nikita Cooley

Undergraduate Theses, Professional Papers, and Capstone Artifacts

Extremes of body size captivate biologists. In insects, the lack of extant giants has prompted the question, what is constraining insect size? While multiple physiological and ecological hypotheses have been presented, there is no widely accepted explanation. One unexplored physiological hypothesis is that large insects are unable to shed metabolic heat rapidly enough and are at increased risk of overheating. My project examines this idea using larvae of the Japanese rhinoceros beetle (Trypoxylus dichotomus), chosen for their huge size, simple body plan, and underground lifestyle. Using CO2 respirometry, I measured larval metabolic rates at room temperature. Although these beetle larvae …
