Fate and Transport of an Estrogen Conjugate 17ß-Estradiol-17-Sulfate in Soil-Water Systems
(North Dakota State University, 2013)
The hypothesis of this study was that a sulfate conjugated estrogen, i.e. 17β-estradiol-17- sulfate (E2-17S), could be a precursor to free estrogens detected in the environment. The objectives of were to investigate the ...
Water Quality Observations of a Headwater Watershed in the Red River Basin and Value of an Interdisciplinary Majors Capstone Course in the Natural Resource Sciences
(North Dakota State University, 2021)
Understanding how change and adaptive management plays a role in natural resource sciences is key to preforming well in the field, as well as evaluating effects of management changes. Therefore, two studies were conducted: ...
Evaluating Dynamic Soil Change in the Barnes Soil Series Across Eastern North Dakota
(North Dakota State University, 2015)
Quantifying long-term, global soil change is of the utmost importance as the human population continues growing and food security needs intensify. North Dakota presents a unique opportunity to study dynamic soil change ...
Vaccine Skeptical Mothers in the Upper Midwest and their Kitchen-based Care Practices
(North Dakota State University, 2021)

(North Dakota State University, 2021)
Pyric-herbivory is a naturally occurring disturbance that historically created shifting mosaics of heterogeneous plant communities and vegetation structure, supporting a biodiverse Great Plains ecosystem. Present land ...
An Assessment of Integrated Weed Management Strategies for Purple Threeawn-Dominated Rangelands
(North Dakota State University, 2013)
Purple threeawn (Aristida purpurea Nutt.) is a native bunch grass that is avoided by grazers. It is capable of dominating old cropland and overgrazed pastures, limiting livestock carrying capacity, and degrading wildlife ...
Investigating the Effects of Alternative Reclamation Practices on Recently Reclaimed Grasslands
(North Dakota State University, 2021)
Surface mining operations in the Northern Plains result in complex grassland ecosystems being dismantled and later systematically reclaimed. Such processes can create long-term challenges with regards to the ecological ...
The Effects of Abiotic Climate Change Factors on Aphid Life History and Populations
(North Dakota State University, 2015)
While the effects of many abiotic factors associated with climate change have not been extensively studied, work on model organisms is beginning to help predict effects on similar species. Research on climate change has ...
