Wetland restoration in the North Dakota Prairie Pothole Region: a macroinvertebrate community perspective
(North Dakota State University, 2024)This study assessed the long-term recovery of aquatic macroinvertebrate communities to wetland restoration. Previous research has suggested that even after a decade post restoration, macroinvertebrate communities may not ... -
Reducing crested wheatgrass (Agropyron cristatum (L.) Gaertn) and improving soil health to facilitate native plant restoration
(North Dakota State University, 2024)Land managers seek to restore diversity of native plant species to areas dominated by introduced crested wheatgrass (Agropyron cristatum (L.) Gaertn.; CWG). This study was initiated by the Bureau of Land Management (BLM) ... -
Trace Element Distribution in Soils of The Pembina Escarpment, North Dakota
(North Dakota State University, 2010)Association of element concentrations for soils of northeastern North Dakota formed from different sources of parent materials were determined based on geochemical data. These soils overlie the Cretaceous Pierre Formation ... -
Interactions of Iron Nanoparticles with Microorganisms
(North Dakota State University, 2010)Nanoparticles (<I 00nm) are being used in different applications such as biomedical, personal care, industrial, and environmental remediation. NZVI particles have unique physico-chemical properties like high surface area ... -
In situ Quantification of Hydrogel Entrapped Microbial Cells
(North Dakota State University, 2010)Entrapped bacteria are used in several applications including food and beverage production, antibiotic production, and wastewater treatment. To date in order to determine the viability of entrapped bacteria, they have ... -
Souris River Dissolved Oxygen Study in Support of Total Maximum Daily Load Development
(North Dakota State University, 2010)The Souris River, a slow moving praire river, originates in the Canadian province of Saskatchewan. The Souris River enters into the United States near Sherwood, North Dakota. The upper portion of the Souris River, from ... -
Intra- and Inter-Specific Variation in Plant Responses to Climate Change
(North Dakota State University, 2022)Plants are sensitive to changing climates and are vulnerable to environmental conditions. In many regions, climate change is shifting temperatures and precipitation patterns, both of which affect various traits in living ... -
Effects of Nanoscale Zero-valent iron (nZVI) on Bacterial Viability: Roles of Growth Phases and Oxidative Stress
(North Dakota State University, 2011)The effect of nanoscale zero-valent iron (nZVI) particles on bacteria from different growth phases was studied. Four bacterial strains including Escherichia coli strains JMI09 and BW25 l l 3, and Pseudomonas putida strains ... -
Using Seed Source Diversity and Species Distribution Modeling for Evaluating Grassland Restoration Success and Suitability
(North Dakota State University, 2022)Seed sourcing for restoration often uses local populations presumed adapted to local environments. This may not be effective under changing climates. Thus, different seed sourcing strategies need testing including multi-source ... -
Late Pleistocene Mountain Glacier Equilibrium Line Altitudes and Paleoclimate Reconstruction in the Great Basin
(North Dakota State University, 2022)This thesis presents new reconstructions of paleoglacier surfaces and Equilibrium Line Altitudes in nine mountain ranges in the northeastern Great Basin during the Last Glacial Maximum. Improved methods for paleoglacier ... -
The Formation and Evolution of the Stockton Island Tombolo, Refined by OSL Geochronology
(North Dakota State University, 2022)Past research conducted on strandplain sequences has shown strandplains can record Holocene lake level changes. The Stockton Island tombolo, of the Apostle Islands National Lakeshore, holds such a record within its eastern ... -
Synergistic Bioactive Enhancement of Phytochemical-Linked Food Safety Relevant and Health Protective Benefits of Select Plant-Based Foods and By-Products
(North Dakota State University, 2022)Under-utilized, ethnic, or traditional plant-based foods, food ingredients, or processed plant by-products have dual functional food safety and health protective benefits due to their rich phytochemical profile. Pre- and ... -
Pupfishes as a System to Test the Predator Naiveté Hypothesis
(North Dakota State University, 2022)Pupfishes are an ideal system to test this the predator naiveté hypothesis because they often occur in isolated springs across a gradient of predation pressure. A convenient tool for assaying antipredator competence are ... -
Environmental and Conservation Sciences Program, College of Graduate and Interdisciplinary Studies
(North Dakota State University, 2011)This study offers an insight on pertinent parameters that may be considered to address potential emerald ash borer {EAB), Agrilus p/anipennis, infestation. The study utilizes a geospatial model, calibrated using empirical ... -
Impact of Groundwater Table on Water Use, Yield, Root Distribution, and Seed Quality of Hard Red Spring Wheat (Triticum aestivum L.)
(North Dakota State University, 2021)The impact of groundwater table depth on hard red spring wheat (Triticum aestivum L.) yield, water use, root distribution, and grain quality were investigated in a greenhouse utilizing the lysimeter technique. Three different ... -
Mycorrhizas and the Context Dependency of Mutualism: Effects of Soil Phosphorus Availability and Community Composition of Arbuscular Mycorrhizal Fungi on Plant Performance and Symbiosis With the Grassland Forb Gaillardia aristata Across Its Northern Range
(North Dakota State University, 2021)Arbuscular mycorrhizal fungi (AMF) colonize roots and provide phosphorus as well as other benefits to hosts in exchange for photosynthate. I explored how the symbiosis between AMF and the native prairie forb Gaillardia ... -
