Evaluation of Alternative Methods for Leafy Spurge Control in the Northern Great Plains
(North Dakota State University, 2018)
Leafy spurge (Euphorbia esula L.) is a costly noxious weed to manage in the Northern Great Plains; it invades rangelands and displaces native and desirable vegetation. Our first objective was to test the recommended full ...
Biological Response to Sulfate Salinity in Richland County, North Dakota
(North Dakota State University, 2016)
Soil salinization is a major threat to agricultural ecosystems. Consequently, an understanding of agro-ecosystem functions affected by increasing levels of soil salinity is critical for land management. The purpose of this ...
Weed Control Effects on Native Species, Soil Seedbank Change, and Biofuel Production
(North Dakota State University, 2011)
Aphthona spp. flea beetles were released in the Little Missouri National Grasslands
(LMNG) in western North Dakota in 1999 to control leafy spurge (Euphorbia esula L.). The
changes in soil seed bank composition and leafy ...
Using Lidar Derived Information for Predicting Beaver Dam Site Selection at Mingo National Wildlife Refuge
(North Dakota State University, 2012)
Characterizing features that influence beaver (Castor Canadensis) to select a site to construct a dam may have important implications for managing damage to select stands of bottomland hardwood forest by beaver activity. ...
Investigating the Influence of Grazing Management Practices on Pollinators to Inform Biodiversity Conservation in Working Grassland-Landscapes
(North Dakota State University, 2017)
Declines in pollinator populations worldwide are threatening pollination that supports native plant communities and global food production. Mitigating these impacts will require conservation actions that promote biodiversity ...
Association and Bioavailability of 17β-Estradiol with Soil and Manure Aqueous Dissolved and Colloidal Fractions
(North Dakota State University, 2014)
Steroidal estrogens in the environment exert toxicological effects at very low concentrations. Furthermore, dissolved and colloidal fractions of soil and manure play an important role in the environmental fate and transport ...
Yield and Quality Prediction Using Satellite Passive Imagery and Ground-Based Active Optical Sensors in Sugar Beet, Spring Wheat, Corn, and Sunflower
(North Dakota State University, 2014)
Remote sensing is one possible approach for improving crop nitrogen use efficiency to save fertilizer costs, reduce environmental pollution, and improve crop yield and quality. Feasibility and potential of using remote ...
Transferability of Regional and Wetland Specific Assessment Methods for a Statewide Approach
(North Dakota State University, 2012)
The transferability and expansion of current wetland assessment methods to other wetland classes and ecoregions throughout the state of North Dakota is the primary goal of this research. During the growing season of 2011, ...
Pest Management of Wheat Stem Sawfly, Cephus Cinctus Norton (Hymenoptera: Cephidae), in Western North Dakota
(North Dakota State University, 2012)
The wheat stem sawfly, Cephus cinctus Norton, is regarded as a major pest of dryland wheat in the Upper Great Plains. For peak emergence of wheat stem sawfly, the most accurate base was 0 C using air temperature, and then ...
Exploring Effects of Weed Management in Agroecosystems: Arthropods, Soil Properties and Soybean Production
(North Dakota State University, 2014)
Soil-dwelling arthropods contribute to agroecosystems, but it’s unclear how specific taxa respond to weed management practices. Objectives were to explore 1) response of Collembola to weed management in a glyphosate-tolerant ...
