An Investigation Of Wild Bee Diversity And Abundance In Plots Managed By The Nature Conservancy In South-Central Nebraska And Of Beneficial Arthropods Associated With Native Nebraska Flora, Dori Ann Porter

Department of Entomology: Dissertations, Theses, and Student Research

Insect pollination is an essential ecosystem service, and bees are the principal pollinators of wild and cultivated plants. Habitat management and enhancement are a proven way to encourage wild bee populations, providing them with food and nesting resources. I examined bee diversity and abundance in plots managed by The Nature Conservancy near Wood River, NE. The plots were seeded with 2 seed mixes at 2 seeding rates: high diversity mix at the recommended rate, high diversity mix double the recommended rate, Natural Resources Conservation Service (NRCS) conservation planting (CP) 25 mix at one-half the recommended rate, and NRCS CP25 mix …

Framing Traits: The Role Of Personality In Framing Effects, Kristen D. Anderson

Department of Political Science: Dissertations, Theses, and Student Research

The processing of messages in the political world is often a function of the frames in which the information is embedded (e.g. Druckman 2001; 2007; Gamson 1989; Iyengar 1991; Jacoby 2001; Nelson, Clawson, and Oxley 1997). These frames have the ability to alter preferences based on how people process information. Research on frames has neglected how an individual’s personality creates the ability to resist or accept the various frames found in political communications. The question at hand is whether framing effects vary based on personality traits and typologies, or if people universally succumb to them when controlling for factors such …

The Effects Of High Pressure Processing On Peanut Sauce Inoculated With Salmonella, Tara K. Stiles

Department of Food Science and Technology: Dissertations, Theses, and Student Research

Recent Salmonella outbreaks have prompted the need for new processing options for peanut products. Traditional heating kill-steps have shown to be ineffective in lipid-rich matrices such as peanut products. High pressure processing is one such option for peanut sauce because it has a high water activity, which has proved to be a large contributing factor in microbial lethality due to high pressure processing. Four different formulations of peanut sauce were inoculated with a five strain Salmonella cocktail and high pressure processed. Results indicate that increasing pressure or increasing hold time increases log₁₀ reductions. The Weibull model was fitted to …

Scraping Behavior In Male White-Tailed Deer As A Potential Means Of Transmitting Chronic Wasting Disease, Travis C. Kinsell

School of Natural Resources: Dissertations, Theses, and Student Research

Chronic wasting disease (CWD) has become a concern for wildlife managers and hunters across the United States. High prevalence of chronic wasting disease (CWD) in older male white-tailed deer (Odocoileus virginianus) suggests that sex-specific social behavior may contribute to the spread of the disease among males. Scraping is a marking behavior performed by male white-tailed deer during the rut in which a pawed depression and associated over-hanging branch are marked with saliva, glandular secretions, urine, and feces. We placed 71 and 35 motion-activated cameras on scrapes in DeSoto National Wildlife Refuge in western Nebraska and eastern Iowa from …

Seasonal Energy And Water Balance Of A Phragmites Australis-Dominated Wetland In The Republican River Basin (Southwestern Nebraska, Usa), Gregory J. Cutrell

School of Natural Resources: Dissertations, Theses, and Student Research

Climate and vegetation can dramatically alter the water cycle on local to regional scales. A change in the surface energy and water balance, especially in arid regions, can have significant impacts on local water availability and, therefore, water resource management. The purpose of this study is to understand the role of climate and vegetation in the energy and water balance of a riparian wetland in the central Great Plains. The site is located near the Republican River in southwestern Nebraska, where decreases in streamflow have been observed in recent decades. In an effort to reduce consumptive use from evapotranspiration (ET), …

Genetic Mapping Of Quantitative Trait Loci Associated With Bioenergy Traits, And The Assessment Of Genetic Variability In Sweet Sorghum (Sorghum Bicolor (L.). Moench), Aatshwaelwe Lekgari Lekgari

Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research

Sweet sorghum, a botanical variety of sorghum is a potential source of bioenergy because high sugar levels accumulate in its stalks. The objectives of this study were to explore the global diversity of sweet sorghum germplasm, and map the genomic regions that are associated with bioenergy traits. In assessing diversity, 142 sweet sorghum accessions were evaluated with three marker types (SSR, SRAP, and morphological markers) to determine the degree of relatedness among the accessions. The traits measured (anthesis date [AD], plant height [PH], biomass yield [BY], and moisture content [MC]) were all significantly different (P< 0.05) among accessions. Morphological marker clustered the accessions into five groups based on PH, MC and AD. The three traits accounted for 92.5% of the variation. There were four and five groups based on SRAP and SSR data respectively classifying accessions mainly on their origin or breeding history. The observed difference between SSR and SRAP based clusters could be attributed to the difference in marker type. SSRs amplify any region of the genome whereas SRAP amplify the open reading frames and promoter regions. Comparing the three marker-type clusters, the markers complimented each other in grouping accessions and would be valuable in assisting breeders to select appropriate lines for crossing. In evaluating QTLs that are associated with bioenergy traits, 165 recombinant inbred lines (RILs) were planted at four environments in Nebraska. A genetic linkage map constructed spanned a length of 1541.3 cM, and generated 18 linkage groups that aligned to the 10 sorghum chromosomes. Fourteen QTLs (6 for brix, 3 for BY, 2 each for AD and MC, and 1 for PH) were mapped. QTLs for the traits that were significantly correlated, colocalized in two clusters on linkage group Sbi01b. Both parents contributed beneficial alleles for most of traits measured, supporting the transgressive segregation in this population. Additional work is needed on exploiting the usefulness of chromosome 1 in breeding sorghum for bioenergy.

Evaluating Hydroperiod Response In The Rainwater Basin Wetlands Of South-Central Nebraska, Richard D. Wilson

School of Natural Resources: Dissertations, Theses, and Student Research

A collection of wetlands in south-central Nebraska make up a region called the Rainwater Basin. This basin contains closed-basin wetlands formed in loess. The wetlands receive water from precipitation and irrigation runoff. Since the early 1900s, wetland area in the basin has decreased dramatically due to intensive agriculture which either altered or removed the wetlands. The Rainwater Basin wetlands provide many ecological services and thus, should be preserved, but are most noted for the resting, breeding, and feeding habitat they provide for millions of migratory birds that is not provided elsewhere in this region along the continental flyway.

Theoretical And Experimental Studies In Nuclear Magnetic Resonance, Adrienne M. Roehrich

Department of Chemistry: Dissertations, Theses, and Student Research

Nuclear magnetic resonance (NMR) is a tool used to probe the physical and chemical environments of specific atoms in molecules. This research explored small molecule analogues to biological materials to determine NMR parameters using ab initio computations, comparing the results with solid-state NMR measurements. Models, such as dimethyl phosphate (DMP) for oligonucleotides or CuCl for the active site of the protein azurin, represented computationally unwieldy macromolecules. ³¹P chemical shielding tensors were calculated for DMP as a function of torsion angles, as well as for the phosphate salts, ammonium dihydrogen phosphate (ADHP), diammonium hydrogen phosphate, and magnesium dihydrogen phosphate. The …

Localization And Binding Characteristics Of Kaposi's Sarcoma-Associated Herpesvirus Bcl-2 Protein In The Prevention Of Apoptosis, Erin T. St.Angelo

Seton Hall University Dissertations and Theses (ETDs)

Kaposi's sarcoma-associated herpesvirus (KSHV) is the causative agent of various diseases, and it encodes a Bcl-2 homolog, KS-Bcl-2. The Bcl-2 family is important in regulating cellular apoptosis. Pro-apoptotic Bcl-2 family members promote apoptosis through mitochondrial pore formation by Bak and Bax, or through BH3 only domain activators and sensitizers. Anti-apoptotic members, such as cellular Bcl-2 prevent apoptosis through interactions with pro-apoptotic proteins, for instance inhibiting pore formation by binding to Bak and/or Bax. Even though, KS-Bcl-2 has been shown to have an anti-apoptotic function like its homolog, it does not bind to either Bak or Bax, and little is known …

The Role Of Social Support On Risk Factors And Frequency Of Non-Suicidal Self-Injury, Erica R. Hoff

Theses and Dissertations

The primary purpose of the current study was to examine the role of social support as a potential protective factor of non-suicidal self-injury (NSSI). Specifically, the study hypothesized that social support would moderate (decrease) the power of the relationship between NSSI risk factors and NSSI frequency. The four risk factors of interest were borderline personality disorder (BPD) traits, an invalidating family environment, depression, and anxiety. Data was collected via self-report questionnaires from a sample of 233 individuals currently enrolled as undergraduates at the University of North Dakota. Results indicated individuals with a history of one or more acts of NSSI …

Evaluation Of Toxicity Analysis For Foundry Sand Specifications, M. Katherine Banks, A. Paul Schwab

JTRP Technical Reports

Byproducts from many industries have the potential to be used as construction materials, but some means is required to determine if the material is environmentally benign. Foundry sands are produced in many states and can be useful as in transportation projects. However, INDOT currently requires the use of the MICROTOX test to assess the potential toxicity of the sands, and this requirement is viewed as an unnecessary impediment by the producers of foundry sands and is a requirement not encountered in other states. Therefore, the goal of this project was to review current requirements for testing of recycled materials, determine …

Theses and Dissertations

Malignant hyperthermia (MH) is a rare, life-threatening, acute hypermetobolic condition that is elicited by exposure to specific drugs used during general anesthesia. These drugs include the volatile anesthetics and the depolarizing muscle blocking antagonist. The morbidities and mortality associated with MH is significant enough that each and every anesthetic provider guards against it

Treatment and management of MH is laborious and extensive. The Malignant Hyperthermia Association of the United States (MHAUS) provides the practitioner with approp1iate treatment measures through established protocol. Dantrolene is the mainstay treatment for MH. However, the management of secondary pathologies that follow in the MH crisis …

Further Purification And Characterization Of Jenseniin P, A Bacteriocin Produced By Propionibacterium Jensenii B1264, Gaoyan Wang

All Theses

Jenseniin P, a bacteriocin discovered by Prince, can inhibit the growth of several strains of propionibacteria and lactobacillus(Prince 1993). Ratnam further purified jenseniin P by ammonia sulfate precipitation and anion exchange chromatography. In that study, partially purified jenseniin P was stable in various pH ranges, SDS concentrations, several solvents, and remained active after holding at 100 ¡C for 60 minutes. The molecular weight was estimated to be between 6 and 9 kDa. In addition, jenseniin P was demonstrated to be inhibitory to Propionibacterium acnes using the spot-on-lawn method. Thus, Ratnam postulated its possible application in acne treatment(Ratnam 1997).

Immigration And Intimate Partner Violence: Exploring The Immigrant Paradox, Emily M. Wright, Michael L. Benson

Criminology and Criminal Justice Faculty Publications

Recent evidence indicates that contrary to some criminological theories, immigrants are less violent than native-born Americans. The relationship between immigrant status and reduced violence appears to hold at both the individual and neighborhood levels of analysis. This phenomenon has been referred to as the immigrant or Latino paradox. It has been suggested, although rarely examined, that cultural differences and strong social networks among immigrants account for their lower violence rates. These factors even appear strong enough to counterbalance the crime-promoting effects of economic disadvantage. This study investigates whether such patterns extend to intimate partner violence. Consistent with research on other …

Conduits are recognized on each of these MVs connecting the pre-Eocene parent beds to the stacked mud cones. The buried MVs are up to 8.4 km wide (4.5 km average) with a central conduit of 1.23 km average diameter and an average mud cone thickness of 0.33 …

Genetic Evidence For High Propagule Pressure And Long-Distance Dispersal In Monk Parakeet (Myiopsitta Monachus) Invasive Populations, Anders Gonçalves Da Silva, Jessica R. Eberhard, Timothy F. Wright, Michael L. Avery, Michael A. Russello

Faculty Publications

The monk parakeet (Myiopsitta monachus) is a successful invasive species that does not exhibit life history traits typically associated with colonizing species (e.g., high reproductive rate or long-distance dispersal capacity). To investigate this apparent paradox, we examined individual and population genetic patterns of microsatellite loci at one native and two invasive sites. More specifically, we aimed at evaluating the role of propagule pressure, sexual monogamy and long-distance dispersal in monk parakeet invasion success. Our results indicate little loss of genetic variation at invasive sites relative to the native site. We also found strong evidence for sexual monogamy from patterns of …

Timber Supply Fundamentals For Extension Forestry Professionals, Thomas J. Straka

Journal of Extension

Timber supply is a term forestry professionals often misuse. It is not the same as timber availability. Competing uses for timber, like bioenergy and carbon credits, make a proper definition important. Timber supply has three subsets: biological potential and physical and economic timber supplies. Plus, there is a temporal aspect that creates a relationship between stock and short-run and long-run timber supplies. A change in stock supply automatically triggers a long-run timber supply response in the opposite direction. Timber supply is a complex issue, and this discussion may help Extension professionals educate landowners and avoid mistakes when using the term.

SDSU Extension Extra Archives

Conditions were very dry for planting last September for the western and central part of the state. And while there were good rains in early October, the cold temperatures led to a slow start for the wheat. Fortunately November was warmer than average, which allowed most locations to get decent fall growth. The northwest part of the state suffered a hard freeze on May 8th causing some freeze injury to the crop. Spring and early summer conditions were wet for most of the state, favoring increased disease pressure. The north central part of South Dakota was dry in June, which …
