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 ...
Aquatic Macroinvertebrate Response to Shifts in Hydroclimatic Variability and Ecohydrological Conditions in Prairie-Pothole Wetlands: Implications for Biodiversity Conservation
(North Dakota State University, 2020)
Ecosystem degradation and subsequent biodiversity loss has plagued freshwater environments globally. Wetland ecosystems, such as the depressional wetlands found in the Prairie Pothole Region of North America, have been ...
Holocene Postglacial Fluvial Processes and Landforms in Low Relief Landscapes
(North Dakota State University, 2020)
Postglacial rivers are part of the relatively young low-relief landscape system left behind by glaciers. Over time, postglacial rivers are susceptible to both minor and major channel planform changes as the Earth and its ...
Freshwater Cyanotoxin Mixtures in Recurring Cyanobacterial Blooms in Voyageurs National Park
(North Dakota State University, 2021)
Algal and cyanobacterial blooms can foul water systems, inhibit recreation, and produce cyanotoxins, which can be toxic to humans, domestic animals, and wildlife. Blooms that recur yearly present a special challenge, in ...
An Agent-Based Model for the Water Allocation and Management of Hydraulic Fracturing
(North Dakota State University, 2022)
An agent-based model (ABM) is developed to simulate the impacts on streamflow and groundwater levels by the dramatic increase of hydraulic fracturing (HF) water use. To develop the agent-based model, institution theory is ...
Investigation of Organic Nitrogen Activity in Biological Processes of Water Resource Recovery Facilities
(North Dakota State University, 2021)
The decrease in effluent inorganic nitrogen concentration in water resource recovery facilities (WRRFs) has been effectively achieved by including or finetuning the biological nutrient removal process. However, soluble ...
