Iguanaland, Joshua Michael Moyar

Graduate Student Theses, Dissertations, & Professional Papers

The green iguana was introduced to the state of Florida in the 1960s. Since then, their populations have exploded, confounding scientists, animal control workers and private citizens in their attempts to eradicate them. While they’ve proven themselves to be nuisance animals — destroying yards and collapsing sidewalks — iguanas still have not conclusively caused ecological damage, meaning researchers can’t be sure that they’re truly invasive. Through this reptilian crisis, private iguana hunting services, like Harold Rondan’s Iguana Lifestyles, LLC, have taken off as a way to capitalize off of iguana carnage. Whether they’re shot, euthanized or even fried and eaten, …

Evaluating Early-Life Characteristics And Responses Of Native Plant Materials For Dryland Restoration, Sophia N. Lasche

Graduate Student Theses, Dissertations, & Professional Papers

Globally, many drylands are in need of restoration due to anthropogenic land use changes, climate change-related biodiversity loss, and broad scale degradation. Within this degradation framework, many perennial grass species and populations have been lost from drylands. A common method of restoring vital perennial grass populations is through seed-based restoration. Using seed-based restoration, or the act of adding desirable seed to a system to restore plant populations, requires a depth of knowledge on species level responses, as well as seed sources within those species. My research examines three workhorse perennial grass species and associated seed sources for dryland restoration, especially …

Quantifying Wastewater Contributions To The Upper Clark Fork River, Claire Utzman

Graduate Student Theses, Dissertations, & Professional Papers

Though algae are at the base of food webs in many rivers, large algal blooms are increasing in frequency and can cause problems with nutrient cycling, depletion of oxygen supplies at night, and release of toxic chemicals. One leading cause of algal blooms is nutrient loading into rivers, and controlling nutrient release in wastewater is one approach that can help limit algal growth. To reduce the intensity of algal blooms in the Clark Fork River in western Montana, numeric nutrient standards were put in place that regulated the release of the nutrients nitrogen and phosphorus into the river from wastewater. …

Density Anomaly Leads To Rift Initiation: Quantifying Active Rifting And Comparison To The East African Rift Zone, Chloe Boucher

Graduate Student Theses, Dissertations, & Professional Papers

Active rifting, elastic failure in the lithosphere from rising density anomalies in the mantle, is fundamental to the Wilson Cycle which describes the cycle of tectonic plates. Active rift zones are common in the oceanic lithosphere but are less common in the thicker continental lithosphere. The current largest active continental rift zone is the East African Rift Zone (EARZ). Although active rifting is fundamental to plate tectonic theory, the mechanics and parameters needed for a density anomaly to initiate a rift have not been undertaken. This model aims to solve the problem of a density anomaly initiating a continental rift …
