Ammonia Oxidizing Archaea in Engineered Water and Wastewater Systems: Presence, Activity and Relationship to Heavy Metal Inhibition, and Disinfectants
(North Dakota State University, 2017)
Ammonia oxidizing archaea (AOA) have been found as a key player in ammonia oxidation. Over the past decade, AOA have been shown in some cases to outnumber ammonia oxidizing bacteria (AOB) in marine, terrestrial and aquatic ...
Impact of Climate Variability on Streamflow and Water Quality in the North Central United States
(North Dakota State University, 2015)
Long-term precipitation, temperature, and streamflow records were used to compare
changes in precipitation and potential evapotranspiration to changes in runoff within 25 stream basins. Historical changes in the region ...
Iron Nanoparticles and Biopolymers for Plant Nutrient Fortification
(North Dakota State University, 2016)
Novel iron (Fe) cross-linked alginate (FCA) beads were used for aqueous phosphate removal. Batch experiments were conducted with the beads using three different concentrations of phosphate (5, 50 and 100 mg PO43--P/L) as ...
Essays on Land Conversion, Crop Acreage Response, and Adoption of Conservation Practices: Evidence from the Dakota's
(North Dakota State University, 2017)
This research is composed of three essays. It highlights the driving factors of land conversion and crop acreage response focusing on North Dakota agriculture and estimates the benefits of conservation land measures at ...
Phosphate Removal and Recovery Using Iron Nanoparticles and Iron Cross-Linked Biopolymer
(North Dakota State University, 2012)
Nanoscale zero-valent iron (NZVI) particles and iron cross-linked alginate (FCA) beads were successfully used for the first time for phosphate removal and recovery. NZVI was successfully used for phosphate removal and ...
Crop Acreage Response Modeling in North Dakota and Greater Midwest
(North Dakota State University, 2017)
Our research consists of two papers. First paper focus on the trend of North Dakota (ND) crop acreage changes and include economic factors (expected prices of crops, input price, crop yield, revenue of crops) and climate ...
Northern Leopard Frogs in North Dakota: Assessing the Conservation Status of a Widespread Amphibian Species
(North Dakota State University, 2015)
North Dakota’s midcontinent location within the Prairie Pothole Region is widely known
for the dense wetlands. These highly productive wetlands are mixed within an agricultural
mosaic which places increased pressure on ...
Examination of the Period of Preparation for Breeding in Male and Female Songbirds
(North Dakota State University, 2017)
In virtually all species, reproduction must be precisely timed to coordinate breeding and rearing of offspring with favorable conditions. It is imperative for individuals to time the highest energetic cost to themselves ...
Chironomids Then and Now: Climate Change Effects on a Tundra Food Web in the Alaskan Arctic
(North Dakota State University, 2019)
Although climate change is a global phenomenon, the Arctic is warming faster than any other region on earth. These climatic changes have driven rapid regional changes over the past half-century in both the physical landscape ...
Understanding the Relationships between Plant Communities, Fish Communities, and Sediment Chemistry in Pristine Shallow Lake Wetlands, Red Lake, MN
(North Dakota State University, 2016)
Over 90% wetland loss in many areas of the United States has triggered extreme concern for declining biodiversity and loss of ecosystem services. Studies assessing ecological characteristics of unaltered wetlands are ...
