Volcanic Impact On Stratospheric Chlorine Chemistry And Perchlorate Formation: Evidence From Ice Cores, Joshua Andrew Kennedy
Volcanic Impact On Stratospheric Chlorine Chemistry And Perchlorate Formation: Evidence From Ice Cores, Joshua Andrew Kennedy
Electronic Theses and Dissertations
Perchlorate, suspected to be chemically formed in both the troposphere and stratosphere, has been recently measured in Arctic snow and ice cores. These comprise both discontinuous snow and ice cores from the Canadian Arctic and a continuous record of perchlorate was compiled from an analysis of Greenland ice cores. While the background perchlorate concentration typically is very low, a few spikes in concentration coinciding with deposition of volcanic sulfate were observed in the Greenland record, suggesting that perchlorate levels in the atmosphere may be impacted by volcanic eruptions. As of yet, no work has been done to investigate the connection …
Understanding How Agricultural Intensification Impacts Ring-Necked Pheasant Distribution And Survival In Eastern South Dakota, Hilary R. Kauth
Understanding How Agricultural Intensification Impacts Ring-Necked Pheasant Distribution And Survival In Eastern South Dakota, Hilary R. Kauth
Electronic Theses and Dissertations
Historically, pheasants (Phasianus colchicus) have thrived in South Dakota in conjunction with successful land retirement programs or early farming practices through the 1950s, which created interspersions of agriculture and native landscapes that were ideal for pheasants. Recently, the Prairie Pothole ecosystem has undergone rapid agroeconomic expansion, effectively reducing ideal interspersions of native prairie and cropland into agriculturally homogeneous landscapes. Indices of pheasant abundance have suggested persistent population declines since 2008, raising concerns regarding landscape suitability. Our goal was to understand how agriculture intensification impacts pheasant ecology. The objectives were to: 1) estimate overwinter hen probability of survival, resource …

Biodegradable Cellulose Films As Alternatives To Plastics, Cecilia Wambui Wanjuu
Biodegradable Cellulose Films As Alternatives To Plastics, Cecilia Wambui Wanjuu
Electronic Theses and Dissertations
Plastics are versatile and have desirable packaging characteristics such as flexibility, durability, and affordability. The production of plastics has increased over the years resulting in concerns about their single-usage and disposal. Since plastics are nonbiodegradable, they have been associated with detrimental health impacts due to the leaching chemicals from the landfills and their accumulation in the natural and marine environment. Cellulose obtained from agricultural residues is a viable substitute because of its low density, biocompatibility, biodegradability, low toxicity, and a strong and stiff structure. However, the extraction of cellulose has been less exploited because of its insolubility in water and …
Biodegradable Biomaterials As Suitable Alternatives To Water Treatment Technologies, Most Farzana Yesmin
Biodegradable Biomaterials As Suitable Alternatives To Water Treatment Technologies, Most Farzana Yesmin
Electronic Theses and Dissertations
Nitrates and phosphates are essential nutrients for plants growth. Their excess presence in water, however, could cause eutrophication affecting the water quality and altering the aquatic ecosystem. Algal blooms and the presence of toxins such as microcystin in freshwater bodies are hazardous to humans, animals, and wildlife. Conventional technologies such as ion exchange, distillation, reverse osmosis, and bioreactors aid immensely to remove nutrients; however, they are expensive. Furthermore, building new nitrate and phosphate treatment units, maintenance and post-disposal are costly too. In this regard, there exists an unmet need for alternative processes that are renewable and cost-effective to treat contaminated …

Determining The Effects Of Plant Extracts And Saltro Nematicide On Hatching, Mortality And Reproduction Of The Soybean Cyst Nematode (Heterodera Glycines), Bishnu Prasad Dhital
Electronic Theses and Dissertations
Soybean cyst nematode (SCN) is a microscopic worm that infects and feeds from the soybean roots, hence robbing the plant of nutrients, and entry wounds may facilitate other pathogens to infect the roots. Current SCN management practices include cultural, chemical, and biological methods. Cultural practices such as, crop rotation with non-host and different tillage practices are not efficient due to the persistent nature of SCN in the soil. Chemical nematicides, though effective, can be expensive, and some are not environmentally sound. SCN resistant soybean varieties are mainly derived from one source, PI 88788 and SCN population have already evolved to …

Due to heavy threats to remaining global floral and faunal diversity, it is imperative we can identify species and quantify ecosystem health to find best practices for land management and conservation. The tallgrass prairies of the Northern Great Plains are one example of a heavily imperiled ecosystem. The tallgrass prairies have been reduced to less one percent of their historical extent and are facing continued loss. Genetic approaches and evolutionary theory offer insights for identifying species and assessing how biodiversity metrics may correlate with ecosystem processes. My two projects aim to address two facets imperative to conservation in the tallgrass …
Employee Development And Turnover: A Moderated Mediation Model Of Employee Perceptions Of Development, Job Satisfaction, Supervisor Support, And Intent To Stay, Ryan Kasdorf
Electronic Theses and Dissertations
As employee turnover continues to be a major concern for organizations, there is increasing evidence that providing development opportunities can be an effective intervention to decrease voluntary turnover. I propose that an integrated theoretical framework of combining Organizational Support Theory (OST) and the Job Demands- Resources Theory (JD-R) is best suited to explain the relationship between employee development and turnover. Moreover, a moderated-mediation model is developed and tested, whereby the relationship between employee perceptions development (EPD) and intent to stay is mediated by job satisfaction, and this indirect relationship is moderated by perceived supervisor support. A large sample (N = …
Exploring Heterogeneous Phenotypes In Response To Stress, Heather S. Deter
Exploring Heterogeneous Phenotypes In Response To Stress, Heather S. Deter
Electronic Theses and Dissertations
This work combines traditional microbiology with bioinformatic and synthetic biology approaches to study antibiotic tolerance. Antibiotic tolerance is a widespread phenomenon that facilitates antibiotic resistance and decreases the effectiveness of antibiotic treatment. Tolerance is distinct from antibiotic resistance, because tolerance is short term survival and typically results from phenotypic variations rather than genetic variation. The molecular mechanisms underlying tolerance are varied and debated in the literature. I have explored two intracellular processes related to tolerance, toxin-antitoxin (TA) systems (Chapter 2) and proteases (Chapter 4). Specifically, I focus on the ratio of antitoxin-to-toxin in type II TA systems, because type II …

The Impact Of Subsurface Physical Characteristics On The Effectiveness Of Subsurface Drainage In The Northern Great Plains, Mehmet Emin Budak
Electronic Theses and Dissertations
World-wide, salinity and sodicity problems are increasing in coastal, irrigated and dryland agricultural systems. Traditional reclamation techniques for saline sodic soils include improving soil drainage by installing subsurface drainage, leaching with high quality water, and applying a source of calcium. However, due to differences in the soil parent material these traditional approach treatments were ineffective in removing sodium and other salts out of the soil profile of South Dakota. Understanding how the surface and subsurface soil characteristics and management interact to affect the sustainability of these systems is the first step in remediation. Each region and soil have a slightly …
