Impacts of Controlled Drainage and Subirrigation in The Red River Valley
(North Dakota State University, 2020)
Drainage water management via controlled drainage (CD) and subirrigation (SI) has shown positive effects on water quality. To determine the impact of CD and SI in the Red River Valley (RRV), data from two fields, each with ...
The Effects of Salinity on Canadian Toad (Anaxyrus hemiophrys) Larvae and Post-Metamorphic Juveniles
(North Dakota State University, 2021)
Sodium Chloride (NaCl) production in the United States is at an all-time high. As weather patterns become harsher through climate change and demands on energy and agriculture increase, evidence of long-term NaCl exposure ...
Late Quaternary Glacier and Climate Change in the Northeastern Great Basin
(North Dakota State University, 2021)
This thesis presents a cosmogenic 10Be exposure chronology for glacial moraines within the Baker Creek valley alongside water balance and climate modeling of Pluvial Lakes Franklin and Clover. These records further limit ...
Effects of Zinc Oxide Nanoparticles and Carbon Nanotubes in Important Crop Species: Plant Growth and Element Uptake
(North Dakota State University, 2021)
Engineered nanomaterials (ENMs) have been developed for various uses in the agriculture industry. The effects of ENMs in plant systems are not yet fully understood. Some studies have reported the different effects of ENMs ...
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 ...
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 ...
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 ...
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 ...
