Seasonal Home Ranges And Habitat Selection Of Three Elk (Cervus Elaphus) Herds In North Dakota, Jacqueline C. Amor, Robert Newman, William F. Jensen, Bradley Rundquist, W. David Walter, Jason R. Boulanger

Biology Faculty Publications

Changes in land use have resulted in range shifts of many wildlife species, including those entering novel environments, resulting in the critical need to understand their spatial ecology to inform ecosystem effects and management decisions. Dispersing elk (Cervus elaphus) were colonizing areas of suitable habitat in the Northern Great Plains, USA, resulting in crop depredation complaints in these areas. Although state resource managers had little information on these elk herds, limited evidence suggested temporal movements into Canada. We collected and analyzed essential information on home range and habitat selection for 3 elk herds residing in North Dakota. We …

Monitoring Landscape Dynamics In Central U.S. Grasslands With Harmonized Landsat-8 And Sentinel-2 Time Series Data, Qiang Zhou, Jennifer Rover, Jesslyn Brown, Bruce Worstell, Danny Howard, Zhuoting Wu, Alisa L. Gallant, Bradley Rundquist, Morgen Walter Victor Burke

Geography & Geographic Information Science Faculty Publications

Remotely monitoring changes in central U.S. grasslands is challenging because these landscapes tend to respond quickly to disturbances and changes in weather. Such dynamic responses influence nutrient cycling, greenhouse gas contributions, habitat availability for wildlife, and other ecosystem processes and services. Traditionally, coarse-resolution satellite data acquired at daily intervals have been used for monitoring. Recently, the harmonized Landsat-8 and Sentinel-2 (HLS) data increased the temporal frequency of the data. Here we investigated if the increased data frequency provided adequate observations to characterize highly dynamic grassland processes. We evaluated HLS data available for 2016 to (1) determine if data from Sentinel-2 …

Delaying Onset Of Diabetes In Native American Populatons, Seth Tramm

Physician Assistant Scholarly Project Papers

Diabetes is a debilitating disease process caused by the body’s inability to control blood glucose levels. With over 30 million diabetics in the United States, and another 85 million prediabetics, the effects of this disease are wide-spread and far-reaching. Native American/Alaska Native populations have a nearly two-fold increase in incidence of diabetes when compared to non-native populations. Risk factors for diabetes in all populations include modifiable risks such as obesity, diet, physical inactivity as well as non-modifiable factors such as age, family history, and ethnicity. Studies have shown that early identification of symptoms, coupled with proper and intentional treatment can …

On The Interpretation Of The Normalization Constant In The Scaling Equation, Karl J. Niklas, Sean T. Hammond

Earth System Science and Policy Faculty Publications

The scaling equation, Y1 = βYα2, has been used empirically and explored theoretically primarily to determine the numerical value and meaning of the scaling exponent, α. The mathematical interpretation of α is clear—it is the quotient of the relative rate of change of Y1 with respect to the rate of change of Y2. In contrast, the interpretation of the normalization constant, β, is obscure, so much so that some workers have rejected the idea that it has any biological importance. With the notable exception of Steven J. Gould's early work, Huxley's dismissal of β largely relegated the study of its …

Detection Of Shelterbelt Density Change Using Historic Apfo And Naip Aerial Imagery, Morgen Walter Victor Burke, Bradley Rundquist, Haochi Zheng

Geography & Geographic Information Science Faculty Publications

Grand Forks County, North Dakota, boasts the highest concentration of shelterbelts in the World. As trees age and reach their lifespan limits, renovations should have taken place with new trees being planted. However, in recent years, the rate of tree removal is thought to exceed the rate of replanting, which can result in a net loss of shelterbelts. Through manual digitization and geographic object-based image analysis (GEOBIA), we mapped shelterbelt densities in the Grand Forks County using historical and contemporary aerial photography, and estimated actual changes in density over 54 years. Our results showed a doubling in shelterbelt densities from …

A Neoclassical Realist’S Analysis Of Sino-U.S. Space Policy, Christopher David Fabian

Theses and Dissertations

During the Cold War, the United States focused its collective policy acumen on forming a competitive, actor-specific strategy to gain advantage over the Soviet Union. The fragmentation of the Soviet Union resulted in a multi-polar geopolitical environment lacking a near-peer rival for the United States. Overwhelming soft and hard power advantages allowed American policy makers to peruse a general, non-actor specific strategy to maintain its hegemonic position. However, the meteoric rise of China as a near-peer competitor in East Asia has challenged this paradigm. In order to maintain its competitive advantage, or at the very least ensure the safety of …

Perceptions Of Teacher-Writers: Initial Influences To Write, Shari L. Daniels, Pamela Beck

Teaching, Leadership & Professional Practice Faculty Publications

This qualitative case study explores perceptions of teacher-writers’ early writing histories and examines their initial influences to write. Interviews and writing artifacts of ten K-12 teacher-writers serve as the primary data source. Findings indicate that teachers with strong identities as readers and/or writers in their K-12 experiences often received positive feedback which encouraged them to develop as writers, while teachers challenged with mechanics often received negative feedback which discouraged them from writing. Revisiting negative writing histories reshaped writing beliefs to influence a positive writing identities. The authors suggest practices for pre-service literacy courses to examine writing histories and to develop …

Analyzing Changes In Rural Town Development And Spatial Morphology: A Case Study Of Lakota, North Dakota, 1908-2018, Kelli Fika

Theses and Dissertations

The face of the many rural towns in the U.S. Great Plains region has changed dramatically. Many towns that boomed in the early 1900s struggle to survive or no longer exist, collectively contributing to the depopulation of the Great Plains. One way to study these changes and understand what influences a rural town’s ability to survive is through analyzing its spatial morphology. Spatial morphology includes looking at changes in roads, buildings, and building plots and how these elements work together to shape town form and function. Previous works have focused mainly on applying this technique to urban areas, but I …

Determination Of Maximum Scour Depth For Spur Dikes Based On A Validated Two-Dimensional Hec-Ras Model, Mathew Lee Cox

Theses and Dissertations

The introduction of spur dikes into a river flow field can have many far-reaching positive effects on the stability of a river channel. While the flow velocity directly at the spur dike tip or crest may increase, a large embayment area downstream of the spur dike will form with reduced flow velocities. Due to the increase in flow velocity at the spur dike, a scour hole will form. Scour is the leading cause of failure of hydraulic structures. In the past many hydraulic structures were tested by building scale prototype models, this method is very costly and hard to model …

Use Of Landsat Satellite Imagery To Identify The Salinization Of Soil Due To Brine Spills In Northwestern North Dakota, Neha Patel

Theses and Dissertations

Oil and gas development in northwestern North Dakota, has resulted in the drilling of more than 32,000 wells and produced large volumes of salt water (brine). Brine spills can have negative impacts on plant and water resources. This research evaluated the detection of brine spills in Bottineau County, North Dakota using Landsat imagery and the Canopy Response Salinity Index (CRSI). The CRSI uses ratios of near-infrared and infrared bands from Landsat imagery. Spill data for Bottineau County from 1975 to 2017 were collected from the North Dakota Department of Health for analysis of spill volume, number of spills, and timing …

Hunting And Fishing Attitudes, Behaviors And Ethics Related To Gender And Aggression, Victoria Williams

Theses and Dissertations

To date, no empirical studies have investigated the relationship between psychopathology (or other constructs) pertaining to hunting and fishing attitudes, behaviors and ethics relating to gender and aggression. Although experienced outdoorspeople assumedly adhere to, or are at least aware of, general hunting and fishing codes of ethics, many disregard them. This study investigates the differences between men and women on these variables by utilizing a newly developed measure of hunting and fishing attitudes and beliefs, the Sportsperson Attitude Scale (SAS) (McDonald, Williams, Sargent & McDonald 2017). This measure was created in order to better understand the potential motivators and reinforcers …
