• Holocene Postglacial Fluvial Processes and Landforms in Low Relief Landscapes 

  Phillips, Zachary Rockford (North Dakota State University, 2020)

  Postglacial rivers are part of the relatively young low-relief landscape system left behind by glaciers. Over time, postglacial rivers are susceptible to both minor and major channel planform changes as the Earth and its ...

• Nitrogen Mineralization Dynamics of Post Harvest Crop Residue in No-Till Systems 

  Alghamdi, Rashad Saeed (North Dakota State University, 2020)

  In North Dakota, adoption of conservation tillage practices has resulted in an accumulation of crop residue remaining on the soil surface. North Dakota producers receive a nitrogen credit for long-term no-till but due to ...

• Aquatic Macroinvertebrate Response to Shifts in Hydroclimatic Variability and Ecohydrological Conditions in Prairie-Pothole Wetlands: Implications for Biodiversity Conservation 

  McLean, Kyle Ian (North Dakota State University, 2020)

• Chironomids Then and Now: Climate Change Effects on a Tundra Food Web in the Alaskan Arctic 

  Lackmann, Alec Ray (North Dakota State University, 2019)

  Although climate change is a global phenomenon, the Arctic is warming faster than any other region on earth. These climatic changes have driven rapid regional changes over the past half-century in both the physical landscape ...

• The Effect of Zinc Oxide Nanoparticles on Plants, and on Host-Pathogen Interactions 

  Deka, Priyanka (North Dakota State University, 2019)

  Zinc oxide nanoparticles (ZnO NPs) are a type of engineered nanomaterial that is currently being explored for use in different aspects of agriculture. So far, research on this area is limited to evaluating the phenotypical ...

• Multi-Element Composition of Triglochin Maritima L. from Contrasting Habitats including Hot Springs and Metal Enriched Areas 

  Sunwar, Sharmila (North Dakota State University, 2011)

  The aim of this PhD research was to study multi-element composition in wetland plants from contrasting habitats, including hot springs, temporary wetlands, and metal-rich areas. Triglochin maritima L. (seaside arrowgrass) ...

• Multi-Element Fingerprinting of River Sediments to Identify Diffuse Pollution Sources 

  Wijeyaratne, Dimuthu Nilmini (North Dakota State University, 2011)

  This study was carried out in the Souris and Turtle Rivers in North Dakota. The aim of this study was to develop multi-element fingerprints of the Souris River and Turtle River sediments and to evaluate the suitability of ...

• Examination of the Period of Preparation for Breeding in Male and Female Songbirds 

  Needham, Katie Beth (North Dakota State University, 2017)

  In virtually all species, reproduction must be precisely timed to coordinate breeding and rearing of offspring with favorable conditions. It is imperative for individuals to time the highest energetic cost to themselves ...

• Understanding the Relationships between Plant Communities, Fish Communities, and Sediment Chemistry in Pristine Shallow Lake Wetlands, Red Lake, MN 

  Hummel, Stephanie Elizabeth (North Dakota State University, 2016)

  Over 90% wetland loss in many areas of the United States has triggered extreme concern for declining biodiversity and loss of ecosystem services. Studies assessing ecological characteristics of unaltered wetlands are ...

• Determining Greenhouse Gas Emissions and Nitrogen Dynamics of Solid Beef Manure Applied to Fargo-Clay Soil of the Red River Valley 

  Niraula, Suresh (North Dakota State University, 2018)
