Economic Analyses of Agricultural Land-Use Change and Agro-Ecosystem Services for Waterfowl in North Dakota
(North Dakota State University, 2014)Understanding the relationship between crop production and wildlife habitat in North Dakota - which contains a large portion of the Prairie Pothole Region - will be essential to the continuation of both in a region facing ... -
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 ... -
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 ... -
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 ... -
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 ... -
Evaluating the Potential Utility of Drones to Deter Birds from Areas of Human-Wildlife Conflict
(North Dakota State University, 2018)Predator-prey dynamics shaped the evolution of morphological and behavioral adaptations that foraging animals use to detect and avoid predators. Wildlife managers can potentially exploit antipredator behavior when attempting ... -
Evaluation of a Nitrate-Assimilating Bacterium for Potential Use in Nitrate Bioremediation
(North Dakota State University, 2013)Increasing levels of nitrate (NO3-N) in water resources have brought about the need to find ever more versatile forms of NO3-N removal from contaminated water. The ability of several microorganisms to transform NO3-N has ... -
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, ... -
Ex Situ Analyses of Non-Native Species Impacts on Imperiled Desert Fishes
(North Dakota State University, 2019)This thesis focuses on interactions between two invasive species, the western mosquitofish (Gambusia affinis) and the red swamp crayfish (Procambarus clarkii), and two desert fishes, the Amargosa pupfish (Cyprinodon ... -
The "Fathead Minnow Factory": Exploring How a Changing Climate Has Influenced Fish and Salamander Communities in the Prairie Pothole Region
(North Dakota State University, 2015)Global climate change has been linked to changing many ecosystem processes. Early literature on climate change and biological systems predominately focused on individual species responses to temperature gradients. However, ... -
First Flowering Date Trends in Clay County, Minnesota and Pollination and Life History Characteristics of Hoary Puccoon (Lithospermum Canescens)
(North Dakota State University, 2013)Plant species in Clay County, Minnesota have been changing their first flowering dates (FFDs) in response to climate changes. To document those shifts, in 2011 and 2012 I recorded phenological data for Clay County, Minnesota. ... -
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 ... -
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 ... -
Identification and Characterization of Fibrous Zeolites in Western North Dakota
(North Dakota State University, 2012)The fibrous zeolite mineral erionite is a concern due to its potential for causing lung disease in humans. Studies have shown that exposure to altered volcanic bedrock containing erionite may be the explanation for a high ... -
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 ... -
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 ... -
