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 ...
Nitrogen Mineralization Dynamics of Post Harvest Crop Residue in No-Till Systems
(North Dakota State University, 2020)
In North Dakota, adoption of conservation tillage practices has resulted in an accumulation of crop residue remaining on the soil surface. North Dakota producers receive a nitrogen credit for long-term no-till but due to ...
Taphonomic, Taxonomic, and Behavioral Diversity of Wormworld Fossil Assemblages from Ediacaran Units of the Western United States
(North Dakota State University, 2020)
The western United States Deep Spring and Wood Canyon formations contain a variety of late Ediacaran fossils, representing the enigmatic Ediacara biota and a metazoan worm-like fauna. The latter, dubbed “Wormworld”, is ...
Evolutionary and Ecological Processes in Conservation and Preservation of Plant Adaptive Potential
(North Dakota State University, 2022)
Anthropogenetic disturbances, such as habitat loss and fragmentation, overexploitation, and climate change have diminished population sizes of many species, increasing risks of population extirpation or species extinction. ...
Graphene Oxide Supported Metal Oxide Nanohybrids for Aqueous Arsenic Removal
(North Dakota State University, 2021)
Arsenic contamination of drinking water is a major public health concern affecting more than 200 million people globally. Iron(Fe)-based adsorbents though promoted for aqueous arsenic removal because of their low cost and ...
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 ...
