Species Distribution Modeling Of Aquilegia Brevistyla (Ranunculaceae): A Critically Imperiled Black Hills Disjunct Species, Eric Daniel Puetz Jan 2024

Species Distribution Modeling Of Aquilegia Brevistyla (Ranunculaceae): A Critically Imperiled Black Hills Disjunct Species, Eric Daniel Puetz

Electronic Theses and Dissertations

Unchecked human activity is contributing to rising levels of greenhouse gas emissions, changes in land use, altered disturbance/fire regimes, spread of invasive species, and loss of biological diversity and related breakdown of ecosystem services. Additionally, climatic shifts may lead to phenological mismatches between species and their environments if these changes outpace a species’ ability to adapt or migrate to a more suitable habitat. Isolated mountain populations are particularly threatened by unpredictable climatic conditions, as they may have limited migration corridors and often lower levels of genetic diversity to move or adapt, respectively. As these negative feedbacks compound on the landscape, …

Mechanical Testing Of Novel Biopolymers For The Replacement Of Petroleum-Based Plastic Hay Bale Net Wrapping, Logan Wolf Jan 2024

Mechanical Testing Of Novel Biopolymers For The Replacement Of Petroleum-Based Plastic Hay Bale Net Wrapping, Logan Wolf

Electronic Theses and Dissertations

The purpose of this thesis is to test biopolymers synthesized from oilseeds or produced from agricultural wastes for large bale net wrapping as a viable alternative to conventional petroleum-based plastics (PBP). The goal is to test and assess novel polymers to guide the synthesis of a benign biodegradable polymer. Biobased net wrapping will significantly reduce ingestion of PBPs in animals such as ruminants to improve digestive health and minimize cattle loss due to plastic disease. Biobased plastics will also achieve partial or complete breakdown shortly after service without depositing microplastics in the environment. This will reduce the risk of damage …

The Hutton Project: Long-Term Agricultural Impacts On Soil Loss And Carbon Dynamics In Eastern South Dakota, Eli Halverson Jan 2024

The Hutton Project: Long-Term Agricultural Impacts On Soil Loss And Carbon Dynamics In Eastern South Dakota, Eli Halverson

Electronic Theses and Dissertations

Long-term and intensified agricultural land management has resulted in increased rates of soil erosion and has altered much of the carbon cycle at regional and global scales. Anthropogenic degradation of soil resources is a barrier to sustainable production, soil functioning, and ecosystem services. It is difficult to quantify the scope of pedogenic changes due to the lack of legacy data and short temporal scales. This study utilized decades to century-old soil information to quantify historical soil erosion losses and changes in soil carbon pools of eastern South Dakota soils. The results show that soils in the region have been significantly …

Climate Change Adaptation For Embankment Through Biogeotechnics, Debayan Ghosh Jan 2024

Climate Change Adaptation For Embankment Through Biogeotechnics, Debayan Ghosh

Electronic Theses and Dissertations

Problematic soil like expansive soil, and frost-susceptible soil causes significant damage to civil infrastructure. The use of calcium-based stabilizers in the treatment of sulfate-rich expansive soils is not suggested due to the formation of ettringite. Infrastructure such as pavements and embankments built on expansive soil are often exposed to the damaging impacts of freeze-thaw cycles in areas prone to seasonal freezing making them vulnerable to cracking and spalling. In this study, a native expansive soil from South Dakota with a sulfate content of more than 10,000 ppm was stabilized using biopolymer and cement. The experimental study investigated the strength and …

The Effects Of Temperature, Flooding, And Goose Feces Addition On Greenhouse Gas Emissions And Ammonification In Four High-Latitude Soils From Western Alaska, Jenna M. Ross Jan 2024

The Effects Of Temperature, Flooding, And Goose Feces Addition On Greenhouse Gas Emissions And Ammonification In Four High-Latitude Soils From Western Alaska, Jenna M. Ross

Electronic Theses and Dissertations

The large carbon (C) stock of wetlands is vulnerable to climate change, especially in high latitudes that are warming at a disproportional rate. Likewise, low-elevation Arctic coastal areas will flood more frequently under climate change and sea-level rise, which may alter goose herbivory and fecal deposition patterns if geese move inland. While temperature, flooding, and feces impact soil C emissions, their interactive effects have been rarely studied. Here, I explore the impact of these interactions on CO2 and CH4 emissions and nitrogen (N) mineralization (ammonification) in soils collected from four plant communities in the Yukon-Kuskokwim (Y-K) Delta, a high latitude …

Plant Pathways Associated With Competition For Soybean Root Colonization By Bradyrhizobium Strains, Athira Sethu Madhavan Jan 2024

Plant Pathways Associated With Competition For Soybean Root Colonization By Bradyrhizobium Strains, Athira Sethu Madhavan

Electronic Theses and Dissertations

Nitrogen is a crucial nutrient for the growth and development of plants. Legume crops like soybeans develop symbiotic associations with soil bacteria from the genus, Bradyrhizobium to obtain fixed nitrogen. In this mutualistic association, rhizobia are released into root nodules that provide a compatible environment for rhizobia to grow and fix nitrogen (Symbiotic Nitrogen Fixation (SNF)). A caveat in such beneficial associations is the competition between different rhizobium strains in soil for infection and nodule occupancy. The elite inoculant strains encounter competition by indigenous rhizobial population in the soil to infect and nodulate a susceptible legume host, because of which …

Movement Ecology Of Paddlefish And Walleye Reveal The Importance Of Continued Interjurisdictional Management In Riverine And Lacustrine Systems, Kaitlyn Bearden

Electronic Theses and Dissertations

Fisheries systems function at broad spatial and temporal scales. Fishes within these systems are often highly mobile and move to locate adequate habitat, to feed and reproduce. As individuals navigate their environment, they potentially cross regulatory boundaries (state or federal) and or encounter physical barriers such as dams. Regulatory boundaries may not physically impede fish movement, but they are visible to fisheries managers thus the fishes within them may be vulnerable to varying management and harvest regulations. Physical boundaries (e.g., dams) are also particularly problematic for highly mobile species in large river systems. In chapter two, I documented that apparent …

Salt sensitivity impacts a significant portion of the population and is an important contributor to the development of chronic kidneydisease. One of the significant early predictors of salt-induced damage is albuminuria, which reflects the deterioration of the renal filtration barrier: the glomerulus. Despite significant research efforts, there is still a gap in knowledge regarding the molecularme chanisms and signaling networks contributing to instigating and/or perpetuating salt-induced glomerular injury. To address this gap, we used 8-wk-old male Dahl salt-sensitive rats fed a normal-salt diet (0.4% NaCl) or challenged with a high-salt diet (4%NaCl) for 3 wk. At the end of the …

The COVID-19 pandemic impacted personal and professional life. For academics, research, teaching, and service tasks were upended and we all had to navigate the altered landscape. However, some individuals faced a disproportionate burden, particularly academics with minoritized identities or those who were early career, were caregivers, or had intersecting identities. As comparative endocrinologists, we determine how aspects of individual and species-level variation influence response to, recovery from, and resilience in the face of stressors. Here, we flip that framework and apply an integrative biological lens to the impact of the COVID-19 chronic stressor on our endocrine community. We address how …

Dichotomous Transactivation Domains Contribute To Growth Inhibitory And Promotion Functions Of Tap73, Dan Li, Catherine Yen Li Kok, Chao Wang, Debleena Ray, Susanne Osterburg, Volker Dötsch, Sujoy Ghosh, Kanaga Sabapathy Jan 2024

Dichotomous Transactivation Domains Contribute To Growth Inhibitory And Promotion Functions Of Tap73, Dan Li, Catherine Yen Li Kok, Chao Wang, Debleena Ray, Susanne Osterburg, Volker Dötsch, Sujoy Ghosh, Kanaga Sabapathy

Division of Basic Science Faculty Publications

The transcription factor p73, a member of the p53 tumor-suppressor family, regulates cell death and also supports tumorigenesis, although the mechanistic basis for the dichotomous functions is poorly understood. We report here the identification of an alternate transactivation domain (TAD) located at the extreme carboxyl (C) terminus of TAp73β, a commonly expressed p73 isoform. Mutational disruption of this TAD significantly reduced TAp73β’s transactivation activity, to a level observed when the amino (N)-TAD that is similar to p53’s TAD, is mutated. Mutation of both TADs almost completely abolished TAp73β’s transactivation activity. Expression profiling highlighted a unique set of targets involved in …

Introduction: Metabolic flexibility is the ability of a system to switch between metabolic substrates. Human and murine skeletal muscle tissues and cells with decreased activity of the regulatory RNA-binding protein, human antigen R (HuR), have decreased capacity for fat oxidation, and thus decreased metabolic flexibility. In this study, we aimed to assess the preference for carbohydrates in mice lacking HuR in skeletal muscle. Methods: Experiments were performed on weight-matched control and HuR knockout mice of both sexes. Palmitate and pyruvate oxidation were performed in mouse muscle following the release of 14CO2. In vivo glucose and lipid uptake were assayed in …
