Nano-fertilisers have only recently been introduced to intensify plant production, and there still remains inadequate scientific knowledge on their plant-related effects. This paper therefore compares the effects of two nano-fertilisers on common sunflower production under field conditions. The benefits arising from the foliar application of micronutrient-based zinc oxide fertiliser were compared with those from the titanium dioxide plant-growth enhancer. Both the zinc oxide (ZnO) and titanium dioxide (TiO₂) were delivered by foliar application in nano-size at a concentration of 2.6 mg·L⁻¹. The foliar-applied nanoparticles (NPs) had good crystallinity and a mean size distribution under 30 nm. …

High-Frequency Data Reveal Differential Dissolved And Suspended Solids Behavior From A Mixed Restored Prairie And Agricultural Catchment, Andrew Miller, Ashlee L. Dere, Tracy Coleman

Chemistry Faculty Publications

Quantifying temporal variability and fluxes within hydrologic catchments is critical to understanding the underlying chemical and physical processes leading to material transport. Measuring variability and fluxes requires sampling at time scales similar to the time scale of process occurrence. This demand has led to the development of automated sampling systems designed to sample at high frequencies, on the order of minutes. While widely deployed in a variety of systems, we installed two high-frequency sampling devices in a single drainage comprised of restored prairie and agricultural land uses in temperate Eastern Nebraska. The sampling systems determined flow rate, conductivity, and turbidity …

Host Plant Defense Produces Species-Specific Alterations To Flight Muscle Protein Structure And Flight-Related Fitness Traits Of Two Armyworms, Scott L. Portman, Gary W. Felton, Rupesh R. Kariyat, James H. Marden

School of Integrative Biological & Chemical Sciences (Formerly Dept. of Biology)

Insects manifest phenotypic plasticity in their development and behavior in response to plant defenses, via molecular mechanisms that produce tissue-specific changes. Phenotypic changes might vary between species that differ in their preferred hosts and these effects could extend beyond larval stages. To test this,we manipulated the diet of southern armyworm(SAW; Spodoptera eridania) and fall armyworm (FAW; Spodoptera frugiperda) using a tomato mutant for jasmonic acid plant defense pathway (def1), and wild-type plants, and then quantified gene expression of Troponin t (Tnt) and flightmusclemetabolismof the adult insects. Differences in Tnt spliceform ratios in insect flight muscles correlate with changes to flight …

Characteristics Of A River Otter (Lontra Canadensis) Maternal Den In The Central Platte River Valley, Ne, Jenna M. Malzahn, Andrew J. Caven, Joshua D. Wiese

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

River otters (Lontra canadensis) encompass a broad geographic range including coastal, riverine, and lacustrine systems. However, knowledge of reproductive behavior and structural den characteristics remain relatively few in the literature, particularly in the Great Plains. Distinctions between the terms “den”, “den site”, “natal den”, and “maternal den” are often ambiguous, obscuring our understanding of river otter’s young-rearing behavior. We used observations and descriptions regarding a single maternal den site and a broad reading of the mustelid literature to propose a more standardized maternal den definition for river otters and specify hypotheses for future research. From 25 April to …

From Political Theology To Critical Political Ethics, Hille Haker

Theology: Faculty Publications and Other Works

Building upon the tradition of the New Political Theology and Iiberation, decolonial, and feminist theology, this article explores the consequences of a decolonial epistemology of theology for ethical theory. It introduces a critical political ethics that concurs with critical, post-structural, and decolonial theory that knowledge and ethics is necessarily situated while standing firm in their ethical orientation towards liberation from injustice. In all these approaches, the question of freedom is of central importance for the development of political ethics, and political theology as well as critical theory raise the question of authority. Rather than presupposing the liberal concept of autonomy …

If Women Were Dragons: A Study Of The Conquest Of Women And Dragons In Ragnar's Saga, The Volsunga Sagas, And The Nibelungenlied, Claire-Elise A. Baalke

English

This thesis is a study displaying the connections between female characters and dragons in Old Norse and Middle High Germanic literature. The main associations that I examine are the ways that female characters and dragons share the characteristics of greed or hoarding, prophetic sight or supernatural power, and "monstrosity" or "Otherness." The fundamental argument is that the women and dragons have common characteristics which define them as dangerous and thereby cause the men or heroes of the tale to feel the need to silence or depower them through conquest. Typically, the dragon is the barrier between the woman and the …

Fate And Effects Of Commercial Crude Oil Bioremediation Products In Arctic Seawater, Taylor R. Gofstein

Chemistry and Biochemistry

With increased oil exploration, development, and transport in the Arctic in recent years, the potential for disastrous oil spills is imminent. Biodegradation, the consumption of contaminants by indigenous microorganisms capable of using them as an energy source, can be enhanced using bioremediation treatments and may be a viable spill remediation method when traditional physical recovery techniques are not. The EPA National Contingency Plan (NCP) product schedule lists oil spill response treatments that can be used in the event of a spill, many of which can stimulate intrinsic biodegradation. However, there is often little to no experimental data demonstrating the effectiveness …

Assessing Adverse Effects Of Mercury In Two Pinniped Species, Marianne Lian

Interdisciplinary Studies

This dissertation studies measures of adverse effects in free-ranging pinnipeds associated with relatively high total mercury ([THg]) or monomethylmercury ([MeHg+]) concentrations, relatively low total selenium ([TSe]) concentrations and/or low TSe:THg molar ratios. Both the Steller sea lion (SSL, Eumetopias jubatus) and Pacific harbor seal (HS, Phoca vitulina richardii) inhabit coasts of the North Pacific, and are considered important sentinel species for One Health (environmental, animal and human health). Relatively high [THg] is reported for some animals in both species, causing concern for adverse effects especially in the developing fetus. Maternal piscivorous diet can expose the fetus to MeHg⁺ at a …

Cultural Adaptations Of Evidence Based Practices In Supporting Children Diagnosed With Autism Spectrum Disorder, Krista P. James

Indigenous Studies

Research shows that early identification and intervention result in a higher quality of life and contribution to society for individuals with Autism Spectrum Disorder (ASD). As society sees an ever-increasing percentage of individuals diagnosed with ASD, identification of culturally responsive, evidence-based practices is of critical importance. While the National Autism Center has provided a guide to evidence-based practices, minimal research has been done to determine if these practices are culturally relevant. This is a community-based formative research project. The purpose of this project was to evaluate the cultural appropriateness of the practices identified as "evidence-based practices" by the National Autism …

Thiamine Deficiency Causes Long-Lasting Neurobehavioral Deficits In Mice, Hui Li, Hong Xu, Wen Wen, Liying Wu, Mei Xu, Jia Luo

Pharmacology and Nutritional Sciences Faculty Publications

Thiamine deficiency (TD) has detrimental effects on brain health and neurobehavioral development, and it is associated with many aging-related neurological disorders. To facilitate TD-related neuropsychological studies, we generated a TD mouse model by feeding a thiamine-deficient diet for 30 days, followed by re-feeding the control diet for either one week or 16 weeks as recovery treatment. We then performed neurobehavioral tests in these two cohorts: cohort of one week post TD treatment (1 wk-PTDT) and 16 weeks post TD treatment (16 wks-PTDT). The TD mice showed no significant difference from control in any tests in the 1 wk-PTDT cohort at …

Long-Term Shifts In Community Structure, Growth, And Relative Abundance Of Nearshore Arctic Fishes: A Response To Changing Environmental Conditions, Justin T. Priest

Fisheries

Environmental conditions influence the presence, species composition, abundance, and growth of fish species in the nearshore Arctic ecosystem. With ongoing shifts in Arctic conditions due to climate change, how fish communities and individual species respond to such changes to environmental variability more broadly is unknown. This study analyzed catch and length data from a long-term fish monitoring project near Prudhoe Bay, Alaska, 2001-2018, to quantify the effects of environmental variables on the overall fish community and on the juveniles of two important whitefishes, Arctic Cisco Coregonus autumnalis and Broad Whitefish Coregonus nasus. Abundance data (n = 1.78 million fish) from …

Trophic Structure Of Rocky Intertidal Communities In Contrasting High-Latitude Environments, Danielle Siegert

Marine Biology

Coastal ecosystems in high latitudes are increasingly impacted by glacial melt and river discharge due to climate change. One way to understand ecosystem responses to these stressors is assessing trophic relationships. The goal of this study was to better understand how hydrographic conditions influence trophic structure in high-latitude rocky intertidal systems. I compared the trophic structure of rocky intertidal assemblages in two regions in the northern Gulf of Alaska that comprise the same regional species pool but are hydrographically distinct, one glacially influenced and one primarily marine influenced. Common macroalgal and invertebrate taxa, as well as particulate organic matter (POM) …
