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. ...
Development and Scale Up of Aqueous Surfactant-Assisted Extraction of Canola Oil for Use as Biodiesel Feedstock
(North Dakota State University, 2012)
In oilseed extraction, alternative extraction media have been studied to replace the traditional solvent, hexane, due to health, safety, and environmental concerns. In this work, aqueous surfactant-assisted extraction was ...
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 ...

Use of Biopolymer Entrapped Sulfate Reducing Bacteria and Metal Nanoparticles for Effective Aqueous Sulfate Removal
(North Dakota State University, 2013)
Sulfate reducing bacteria (SRB) isolated from activated sludge were used to investigate sulfate removal from aqueous solution using calcium alginate entrapped SRB in batch studies with ethanol and lactose as the carbon ...
Multi-Element Fingerprinting of Wetland Soil for Rapid Assessment
(North Dakota State University, 2013)
Wetland functions and conditions are determined by hydrologic, soil physiochemical, and biotic states. Information obtained from soil analysis can convey wetland history due to hydrologic regime, soil chemical changes, ...
In Vitro Enrichment of Phosphorylated Proteins From Synchronously Excysted Cryptosporidium Parvum
(North Dakota State University, 2014)
Cryptosporidium is an enteric protozoan parasite that causes cryptosporidiosis and there is no effective drug treatment available. Two studies were conducted. In the first, a novel protocol was developed for the rapid in ...
Morphological Differences and Diversity of Small Mammal Species
(North Dakota State University, 2016)
Small mammals play important roles in ecosystems, but are often overlooked due to their small size and plentiful abundance. Two studies evaluated the morphological differences and diversity of small mammal species based ...
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 ...
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, ...
