'As A Woman, As A Mother, As A Farmer': Understanding Women's Agricultural Practices, Perceptions And Adaption To Climate Change In The Upper Midwest, Erin Kline

Electronic Theses and Dissertations

This research shows that women’s farming identities are changing inline with their increased representation in agriculture in general, but specifically reflective of women’s increased autonomy in decision-making. This is especially evident among women who are primary operators, but increased equality is also apparent for women farming in partnerships. These key findings align with current identity research (see Brasier et al. 2014) and demonstrate the multiplicity of roles that women fulfill on the farm, and how these roles change in alignment with farming practices. This exploratory research draws from Feminist standpoint theory and situated knowledge to develop qualitative interview protocol to …

A Little Goes A Long Way: Pressure For College Students To Succeed, Jennifer R. Davis

The Journal of Undergraduate Research

When college students begin college they experience pressure from multiple sources. For example, they experience pressure from their parents to succeed, from their professors, and pressure from themselves to do well in classes. This pressure could lead to high anxiety and possibly even poor performance in classes. Prior research that has examined the impact of anxiety on performance includes the Yerkes-Dodson law and the Processing Efficiency Theory. Both argue that anxiety increases the performance to a point, but then performance decreases again with too much pressure. The Processing Efficiency Theory also includes motivation. This motivation increases the drive to succeed …

Environmental Variables Measured At Multiple Spatial Scales Exert Uneven Influence On Fish Assemblages Of Floodplain Lakes, Daniel J. Dembkowski, L.E. Miranda

Natural Resource Management Faculty Publications

We examined the interaction between environmental variables measured at three different scales (i.e., landscape, lake, and in-lake) and fish assemblage descriptors across a range of over 50 floodplain lakes in the Mississippi Alluvial Valley of Mississippi and Arkansas. Our goal was to identify important local- and landscape-level determinants of fish assemblage structure. Relationships between fish assemblage structure and variables measured at broader scales (i.e., landscape-level and lake-level) were hypothesized to be stronger than relationships with variables measured at finer scales (i.e., in-lake variables). Results suggest that fish assemblage structure in floodplain lakes was influenced by variables operating on three different …

Gape:Body Size Relationship For Smallmouth Bass, Craig L. Schake, Daniel J. Dembkowski, Melissa R. Wuellner

Natural Resource Management Faculty Publications

The types and sizes of prey fishes consumed by predatory fish often are limited by gape dimensions of the predator (Slaughter and Jacobson 2008). In general, the size of prey consumed is positively related to predator size when prey are available across a wide range of sizes (Werner and Hall 1974). Opportunistic predators with large gape dimensions, such as smallmouth bass (Micropterus dolomieu), may consume a wide range of prey types and sizes, thereby exerting top-down influences on prey population dynamics and potentially restructuring aquatic communities (e.g., Werner and Hall 1974, Jackson 2002). Although feeding ecology of smallmouth bass varies …

Bed-Site Selection By Neonatal White-Tailed Deer In Central North Dakota, Brian A. Schaffer, Jonathan A. Jenks, Troy Grovenburg, William F. Jensen

Natural Resource Management Faculty Publications

Understanding bed-site selection and vegetation characteristics provides valuable information for population management (Verme 1977, Huegel et al. 1985a, Nelson and Woolf 1987). Predation and other natural-caused mortalities of white-tailed deer (Odocoileus virginianus) neonates are most likely to occur within the first 60 days of life; a time period when selected habitat characteristics are vital to survival (Verme 1977, Huegel et al. 1985a, Nelson and Woolf 1987, Grovenburg et al. 2010). Prior to the study of Grovenburg et al. (2010), limited research had been completed on bed-site selection of neonatal white-tailed deer in the grasslands of the Northern Great Plains. In …

Detecting The Influence Of Best Management Practices On Vegetation Near Ephemeral Streams With Landsat Data, Matthew Rigge, Alexander Smart, Bruce Wylie, Kendall De Van Kamp

Natural Resource Management Faculty Publications

Various best management practices (BMPs) have been implemented on rangelands with the goals of controlling nonpoint sourcepollution, reducing the impact of livestock in ecologically important riparian areas, and improving grazing distribution.Providing off-stream water sources to livestock in pastures, cross-fencing, and rotational grazing are common rangeland BMPsthat have demonstrated success in drawing livestock grazing pressure away from streams. We evaluated the effects of rangelandBMP implementation with six commercial-scale pastures in the northern mixed-grass prairie. Four pastures received a BMPsuite consisting of off-stream water, cross-fencing, and deferred-rotation grazing, and two pastures did not receive BMPs. Wehypothesized that the BMPs increased the quantity …

Phenology Of Annulus Formation In Walleye And Smallmouth Bass Otoliths, Brianna J. Graff, Daniel J. Dembkowski, Melissa R. Wuellner

Natural Resource Management Faculty Publications

Walleye Sander vitreus and smallmouth bass Micropterus dolomieu were sampled monthly (May-October) from Lake Sharpe, South Dakota during 2006 and 2007 to estimate the timing of otolith annulus formation and to evaluate the influence of fish age, sex, and sample location (walleye only) on the timing and detection of annulus formation. Timing of annulus formation was evaluated using marginal increment analysis. Walleye samples were stratified by age, sex, and sample location (i.e., upper and lower Lake Sharpe) and smallmouth bass samples were stratified by age and sex. Monthly mean marginal increment measurements for both species generally increased from May to …

Quantification Of Α-Ketoglutarate Cyanohydrin In Swine Plasma By Ultra-High Performance Liquid Chromatography Tandem Mass Spectrometry, Brendan L. Mitchell, Gary A. Rockwood, Brian A. Logue

Chemistry and Biochemistry Faculty Publications

Determination of exposure to cyanide can be accomplished by direct cyanide analysis or indirectly by analysis of cyanide detoxification products, such as thiocyanate and 2-amino-2-thiazoline-4-carboxylic acid. A potentially important marker and detoxification product of cyanide exposure, α-ketoglutarate cyanohydrin (α-KgCN), is produced by the reaction of cyanide and α-ketoglutarate. Therefore, an ultra high-performance liquid chromatography tandem mass spectrometry method to determine α-KgCN in plasma was developed. Swine plasma was spiked with α-KgCN and α-KgCN-d₄ (internal standard) and proteins were precipitated with 1% formic acid in acetonitrile. After centrifugation, the supernatant was dried, reconstituted, separated by reversed phase high performance liquid …

Toxicokinetic Profiles Of Α-Ketoglutarate Cyanohydrin, A Cyanide Detoxification Product, Following Exposure To Potassium Cyanide, Brendan L. Mitchell, Raj K. Bhandari, Vikhyat S. Bebarta, Gary A. Rockwood, Gerry R. Boss, Brian A. Logue

Chemistry and Biochemistry Faculty Publications

Poisoning by cyanide can be verified by analysis of the cyanide detoxification product, α-ketoglutarate cyanohydrin (α-KgCN), which is produced from the reaction of cyanide and endogenous α-ketoglutarate. Although α-KgCN can potentially be used to verify cyanide exposure, limited toxicokinetic data in cyanide-poisoned animals are available. We, therefore, studied the toxicokinetics of α-KgCN and compared its behavior to other cyanide metabolites, thiocyanate and 2-amino-2-thiazoline-4-carboxylic acid (ATCA), in the plasma of 31 Yorkshire pigs that received KCN (4 mg/mL) intravenously (IV) (0.17 mg/kg/min). α-KgCN concentrations rose rapidly during KCN administration until the onset of apnea, and then decreased over time in all …

Evidence For 20th Century Climate Warming And Wetland Drying In The North American Prairie Pothole Region, Brett A. Werner, W. Carter Johnson, Glenn R. Guntenspergen

Natural Resource Management Faculty Publications

The Prairie Pothole Region (PPR) of North America is a globally important resource that provides abundant and valuable ecosystem goods and services in the form of biodiversity, groundwater recharge, water purification, flood attenuation, and water and forage for agriculture. Numerous studies have found these wetlands, which number in the millions, to be highly sensitive to climate variability. Here, we compare wetland conditions between two 30-year periods (1946–1975; 1976–2005) using a hindcast simulation approach to determine if recent climate warming in the region has already resulted in changes in wetland condition. Simulations using the WETLANDSCAPE model show that 20th century climate …

Chemistry and Biochemistry Faculty Publications

Since the first reported cases of ducks infected with a previously unknown flavivirus in eastern China in April 2010, the virus, provisionally designated Duck Tembusu Virus (DTMUV), has spread widely in domestic ducks in China and caused significant economic losses to poultry industry. In this study, we examined in detail structural, antigenic, and evolutionary properties of envelope (E) proteins of six DTMUV isolates spanning 2010–2012, each being isolated from individual farms with different geographical locations where disease outbreaks were documented. Structural analysis showed that E proteins of DTMUV and its closely related flavivirus (Japanese Encephalitis Virus) shared a conserved array …

Optimal Placement Of Off-Stream Water Sources For Ephemeral Stream Recovery, Matthew Rigge, Alexander Smart, Bruce Wylie

Natural Resource Management Faculty Publications

Uneven and/or inefficient livestock distribution is often a product of an inadequate number and distribution of watering points.Placement of off-stream water practices (OSWP) in pastures is a key consideration in rangeland management plans and is criticalto achieving riparian recovery by improving grazing evenness, while improving livestock performance. Effective OSWPplacement also minimizes the impacts of livestock use radiating from OSWP, known as the ‘‘piosphere.’’ The objective of thisstudy was to provide land managers with recommendations for the optimum placement of OSWP. Specifically, we aimed toprovide minimum offset distances of OSWP to streams and assess the effective range of OSWP using Normalized …
