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. ...
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, ...
Development and Genetic Regulation of the Novel Abdominal Appendages in the Male Sepsid Fly, Themira Biloba
(North Dakota State University, 2013)
Evolutionary novel structures are structures with no known homology. Novel structures often provide a novel function to the organism. Some species of sepsid flies (family Sepsidae) have evolved novel abdominal appendages ...
Alluvial Fans in the McMurdo Dry Valleys: A Proxy for Melting Along Terrestrial Margins of the East Antarctic Ice Sheet
(North Dakota State University, 2013)
Surface melting along Antarctic ice sheet margins is the most poorly understood input in models of future sea level rise. Alluvial fans in the McMurdo Dry Valleys originate from meltwater produced from high-elevation ...
Interactions between Ultraviolet Light and Soybean Aphid, Aphis Glycines Matsumura (Hemiptera: Aphididae)
(North Dakota State University, 2013)
Global increases in ultraviolet (UV) radiation have led to greater interest in its current and potential effects on organisms, including insects and plants. Here we report the short-term effects of UV on soybean aphids ...
