Influences on Fungal Community Composition in Roots and Soil of Coffee and Other Rubiaceae in Costa Rica
(North Dakota State University, 2019)
Belowground fungi interact with plants directly as pathogens and mutualists, and indirectly as nutrient cyclers, yet the factors governing fungal community composition are poorly understood. Here I examined root and soil ...
Factors Affecting Soil Total Mercury, Carbon and Nitrogen Distributions in Seasonal Pond Basins within a Northern Hardwood Forest in Minnesota, USA
(North Dakota State University, 2016)
Forests are sites for mercury deposition, where accumulation in aquatic environments can occur. Soil total mercury (THg), C and N to 15 cm were studied in ten seasonal pond basins in a northern hardwood forest (Minnesota, ...
Evidence of Inbreeding and Divergence in the Western Prairie Fringed Orchid (Platanthera praeclara)
(North Dakota State University, 2018)
The conversion of grasslands to agriculture land has made the tall grass prairie one of the world’s most endangered ecosystems and has played a key role in the decline of one particular species of rare endangered orchid, ...
Antipredator Behavior and Morphology in Isolated Cyprinodont Fishes
(North Dakota State University, 2018)
For desert fishes in the American Southwest, predation by invasive species has triggered massive population declines for decades, leaving researchers speculating on the underlying cause. It has been shown that Post-Pleistocene ...
Change in Reference Condition Wetlands and Road Dust Impacts on Spider Mites
(North Dakota State University, 2017)
Increased disturbance from agriculture and the changing climate in the Prairie Pothole Region (PPR) of North Dakota may cause shifts in vegetation on wetland systems as well as increases in spider mite populations on ...
Glutaraldehyde Removal from Produced Water Using Photolysis and Photocatalysis
(North Dakota State University, 2017)
Glutaraldehyde (GA) has been used extensively as a biocide in hydraulic fracturing fluids leading to the contamination of the compound in produced water. In this study, the performances of photolysis and photocatalysis for ...
Post-Fire Damage and Corrosion in Structural Steels: Characterization and Prevention
(North Dakota State University, 2021)
Steel structures frequently experience extreme service conditions such as fire accidents, corrosion, etc., resulting in significant deterioration, reduced service life, and increased maintenance cost. Almost 0.5 million ...
Dual Role of Phenolic Bioactives in Improving Functional Health Benefits and Abiotic Stress Resilience in Barley
(North Dakota State University, 2021)
Food insecurity, climate change, and public health challenges are interconnected and pressing issues facing humanity in the 21st century. Therefore, it is imperative to address key obstacles underlying food and nutritional ...
Proposed Methods for the Nondecreasing Order-Restricted Alternative in a Mixed Design
(North Dakota State University, 2020)
Nonparametric statistics are commonly used in the field of statistics due to their robustness when the underlying assumptions are violated for the usual parametric statistics. In this dissertation, we proposed eight ...
Understanding Host Resistance and Pathogen Biology in the Wheat-Fusarium graminearum Pathosystem
(North Dakota State University, 2020)
Fusarium head blight (FHB) is a major challenge in global wheat production. In the United States, the disease is predominantly caused by the fungus Fusarium graminearum. Utilization of FHB-resistant wheat cultivars integrated ...
