Assessment of Watershed Health on Intermittent Watersheds in Southwestern North Dakota
(North Dakota State University, 2017)
Watersheds are complex systems that are influenced by many factors including geomorphology, climate, soil, vegetation, and land management. Due to this complexity, a watershed assessment that evaluates both the riparian ...
Screening Hard Red Spring Wheat Cultivars for Reduced Phosphorus Fertilizer Requirement
(North Dakota State University, 2017)
Phosphorus (P) is a common macronutrient required for hard red spring (HRS) wheat (Triticum aestivum L.) growth and yield expression, and is a significant expense for farmers. The objective of this study was to screen 89 ...
Sugarbeet Yield and Quality Response to Nitrogen Fertilizer Rate and In-Season Prediction of Yield and Quality Using Active-Optical Sensor
(North Dakota State University, 2016)
Nitrogen (N) management is one of the important factors in sugarbeet production. Under-application of N-fertilizer results in lower root yield while over-application of N-fertilizer can result in decreased sugar concentration ...
A Study of the Relationship Between Plains Sharp-Tailed Grouse Nest Site Selection and Survival and Ecological Site Descriptions in the Northern Plains
(North Dakota State University, 2019)
Nest site selection and nesting success of plains sharp-tailed grouse were examined on the Grand River National Grassland in South Dakota during the nesting season from 2009-2012. We used conditional logistic regression ...
Environmental Socialization: A Case Study on Formative Influences
(North Dakota State University, 2018)
Twenty-first century social-ecologic systems are in the midst of a complex adaptive cycle. There is growing evidence to suggest the existence of a psycho-social developmental process whereby a person becomes situated in ...
Bending and Force Recovery in Polymer Films and Microgel Formation
(North Dakota State University, 2018)
To determine correlation between geometry and material three different model films: polymethylsiloxane (PDMS), polystyrene (PS), and polycarbonate (PC), were singly bent and doubly bent (forming D-cones). Bends were chosen ...
Selection for Low Calcium Tolerance in Brassica rapa
(North Dakota State University, 2018)
Ecosystems across a landscape can vary in their selection pressures and therefore can vary in the species that are able to survive there. Selection pressures applied on a species found in multiple ecosystems may lead to ...
IfSAR DTM-derived Predictive Flood Models: A Cost-effective Approach to Target Site- Specific Mosquito (Diptera: Culicidae) Control Efforts
(North Dakota State University, 2016)
The study area is the 400 km2 floodplain and wetlands of the upper Missouri River, located in the northwestern corner of North Dakota, near the community of Williston. Regional climate is semiarid, yet the Williston vector ...
Plant-Stand Count and Weed Identification Mapping Using Unmanned Aerial Vehicle Images
(North Dakota State University, 2018)
Modern agriculture encounters several challenges these days. There is a vital need for spatial data about plant and weed distributions. Obtaining accurate knowledge of the plants and weeds distribution in the field with ...
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 ...
