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 ...
An Assessment of Integrated Weed Management Strategies for Purple Threeawn-Dominated Rangelands
(North Dakota State University, 2013)
Purple threeawn (Aristida purpurea Nutt.) is a native bunch grass that is avoided by grazers. It is capable of dominating old cropland and overgrazed pastures, limiting livestock carrying capacity, and degrading wildlife ...
The Effects of Abiotic Climate Change Factors on Aphid Life History and Populations
(North Dakota State University, 2015)
While the effects of many abiotic factors associated with climate change have not been extensively studied, work on model organisms is beginning to help predict effects on similar species. Research on climate change has ...
Laboratory and Greenhouse Evaluation of FeEddha Fertilizers of Differing Quality
(North Dakota State University, 2013)
Commercial iron ethylene diamine di(hydroxyl phenyl acetic acid) (FeEDDHA) fertilizers containing the same Fe percent and applied at the same FeEDDHA rate control Fe deficiency chlorosis (IDC) differently due to differing ...
