Micro-Pore Parametrics for Optimal Hyperfiltration of Conservative Contaminants
(North Dakota State University, 2012)In compacted Na-montmorillonite membranes, the pore-size, and surface charge will influence filtration processes of solutes. A dead-end hyperfiltration setup was utilized to: (a) study the intrinsic retention, membrane ... -
Mid-Wisconsinan Climate Reconstruction Based on Fossil Beetles from Six Mile Creek, Ithaca, New York
(North Dakota State University, 2018)The history of the Mid-Wisconsinan sub-stage in northeastern North America is one of large climatic oscillations. Fossil beetles were extracted from two horizons at the Six Mile Creek site, New York. A total of 738 individuals ... -
Migratory Ecology and Wing Morphology of North Dakota Bats
(North Dakota State University, 2019)Understanding links between a species’ migratory behavior, wing morphology, and foraging strategy can provide insight into factors driving the evolution of behavioral and ecological responses. The first chapter of this ... -
Morphological Differences and Diversity of Small Mammal Species
(North Dakota State University, 2016)Small mammals play important roles in ecosystems, but are often overlooked due to their small size and plentiful abundance. Two studies evaluated the morphological differences and diversity of small mammal species based ... -
Multi-Element Analysis on Riparian Wetlands and River Sediment in North Dakota
(North Dakota State University, 2014)River sediment, transfer metals, nutrients and pollutants from various sources and tributaries within a catchment, and deposit sediment whenever the flow rate of water is low. Multi-element fingerprinting technique could ... -
Multi-Element Composition of Triglochin Maritima L. from Contrasting Habitats including Hot Springs and Metal Enriched Areas
(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
(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 ... -
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, ... -
Mycorrhizas and the Context Dependency of Mutualism: Effects of Soil Phosphorus Availability and Community Composition of Arbuscular Mycorrhizal Fungi on Plant Performance and Symbiosis With the Grassland Forb Gaillardia aristata Across Its Northern Range
(North Dakota State University, 2021)Arbuscular mycorrhizal fungi (AMF) colonize roots and provide phosphorus as well as other benefits to hosts in exchange for photosynthate. I explored how the symbiosis between AMF and the native prairie forb Gaillardia ... -
The Need to Move: Exploring Landscape Connectivity through the Eyes of the Northern Leopard Frog
(North Dakota State University, 2017)The northern leopard frog (Rana pipiens) is a species that depends on landscape connectivity to complete its lifecycle. However, due to historic and present anthropogenic landscape changes, this species encounters a variety ... -
Neonicotinoids: Assessing their Distribution and Biological Effects to Prairie Pothole Wetlands
(North Dakota State University, 2018)The use of neonicotinoid pesticides is widespread throughout agricultural regions, including the Prairie Pothole Region (PPR) of North America. Recently, there have been growing concerns regarding the use of these pesticides ... -
Nitrogen Mineralization Dynamics of Post Harvest Crop Residue in No-Till Systems
(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 ... -
Northern Leopard Frogs in North Dakota: Assessing the Conservation Status of a Widespread Amphibian Species
(North Dakota State University, 2015)North Dakota’s midcontinent location within the Prairie Pothole Region is widely known for the dense wetlands. These highly productive wetlands are mixed within an agricultural mosaic which places increased pressure on ... -
OSL Dating of High-Elevation Alluvial Sediments: McMurdo Dry Valleys, Antarctica
(North Dakota State University, 2015)High-elevation alluvial fans in the McMurdo Dry Valleys are a record of short-term, occasional melting events along the margins of the East Antarctic Ice Sheet. Sediment samples were dated from five fans using Optically ... -
