The Wheat-Hessian Fly Interaction: Co-Evolution and Ecology in an Economically Important Plant-Insect System
(North Dakota State University, 2013)
The study of wheat’s H-gene mediated resistance to Hessian flies examined the cost of the constitutively expressed H-gene which functions in the plant’s surveillance system and the cost of the downstream induced response. ...
Gauging the Perceptions of High School Students in Different Demographics on Environmental Education Topics
(North Dakota State University, 2016)
Environmental education is a topic that has been promoted by advocates and researchers for more than three decades; however, a majority of public schools still fail to cover the fundamental basics of environmental education ...
Exploring Land Conservation Using Economic and Geospatial Models
(North Dakota State University, 2015)
Three different, but related studies on conservation in North Dakota were completed. Expansion of Devil’s Lake over the past 20 years has flooded farmland, towns, and roads, causing economic damage and distress. Retirement ...
Conspectus of Aeptini Stål, 1871 (Hemiptera: Heteroptera: Pentatomidae: Pentatominae)
(North Dakota State University, 2017)
The Pentatominae tribe Aeptini is revised. A key to the known genera is provided, together with redescription and figures. The genus Paramenestheus is revised, including a key to the species and figures to all the included ...
Evaluation of Active Optical Ground-Based Sensors to Detect Early Nitrogen Deficiencies in Corn
(North Dakota State University, 2014)
Corn (Zea mays, L) is an important world crop used as livestock feed, human consumption and ethanol production. Early in-season loss of nitrogen (N) continues to be a problem in corn. Ground-based active optical sensors ...
Using Light Detection and Ranging (LiDAR) Technology to Assess Bird-Habitat Relationships: A Case Study from the Northwoods of Maine
(North Dakota State University, 2012)
Airborne light detection and ranging (LiDAR) is a remote sensing technology that quantifies the travel time of photons emitted in pulses from a LiDAR instrument to travel to and reflect back from objects. Knowing the travel ...
Winter Wheat Management for Improving Soil Quality and Reducing Greenhouse Gas Emissions
(North Dakota State University, 2014)
Carbon dioxide (CO2) and nitrous oxide (N2O) concentrations in the atmosphere have greatly increased in recent times. Intensive agricultural practices, combustion of fossil fuels, deforestation, and wetland drainage have ...
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 ...
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 ...
The Yellowstone River Waterfowl Hunting Closure in Eastern Montana: Evaluation of Private Landowner Attitudes
(North Dakota State University, 2013)
Wildlife managers now hypothesize the limiting factor regarding waterfowl hunting opportunity and goose harvest in the lower Yellowstone River Valley is hunter access rather than waterfowl abundance. This study used a ...
