Seasonal And Habitat-Based Prey Diversity Of Bobcats, Lynx Rufus, In Big Bend National Park, Texas, Ellen Stringer Browning

Biology Dissertations - Archive

The bobcat (Lynx rufus) population in Big Bend National Park (BIBE) provides an excellent opportunity for study due to the varied arid habitat in which they exist, the dynamic nature of their environment, and the paucity of scientific documentation on this unexploited population. As an abundant carnivore, the bobcat is crucial to BIBE's community ecology and trophic structure, emphasizing the need to investigate, in depth food habits in relation to environmental factors. Bobcats feed on a variety of small vertebrates, primarily lagomorphs and rodents, and are also known to take down large prey, such as mule deer and white tailed …

The Charter Of The Forest: Evolving Human Rights In Nature, Nicholas A. Robinson

Elisabeth Haub School of Law Faculty Publications

Carta de Foresta, the Charter of the Forest of 1217, is among the first statutes in environmental law of any nation. Crafted to reform patently unjust governance of natural resources in 13th century England, the Charter of the Forest became a framework through which to reconcile competing environmental claims, then and into the future. The Charter confirmed the rights of “free men.” Kings resisted conceding these rights. When confronted with violation of the Charter, barons and royal councils obliged kings repeatedly to reissue the Forest Charter and pledge anew to obey its terms.

Adapting The Law Of Armed Conflict To Autonomous Weapon Systems, Kenneth Anderson, Daniel Reisner, Matthew Waxman

Scholarly Articles in Law Reviews & Journals

As increasingly automated – and in some cases fully autonomous – weapon systems enter the battlefield or become possible, it is important that international norms to regulate them head down a path that is coherent and practical. Contrary to the claims of some advocates, autonomous weapon systems are not inherently illegal or unethical. The technologies involved potentially hold promise for making armed conflict more discriminating and causing less harm on the battlefield. They do pose important challenges, however, with regard to law of armed conflict rules regulating the use of weapons. Those challenges demand international attention and special processes for …

Awareness Of Privilege And Oppression Scale-2: Construction And Initial Validation, Michael J. Mcclellan

Theses and Dissertations--Educational, School, and Counseling Psychology

The purpose of this study was to revise the Awareness of Privilege and Oppression Scale (Montross, 2003) and to improve upon the psychometric properties of the original instrument. The APOS-2 is a diversity training outcome measure that is designed to measure the social justice-related construct awareness of privilege and oppression. I retained 26 items from the original APOS (Montross, 2003) and utilized an expert focus group to generate new test items for the APOS-2. Feedback from an expert rater group was solicited and then incorporated into the APOS-2 to help reduce the number of items, improve item content, and evaluate …

Investigating Ability Grouping And Self-Efficacy In Middle Grade Mathematics, Ashley G. Hall

Theses and Dissertations--Educational, School, and Counseling Psychology

Ability grouping has been prevalent in American schools for over a century (Burris & Welner, 2005; Museus, Palmer, Davis & Maramba, 2011; Slavin, 1990). Although ability grouping has been studied in terms of student performance, little research has examined the relationship between this practice and student motivation. The purpose of this study was to examine middle school students’ (N = 2,279) mathematics self-efficacy and its sources in ability grouped mathematics courses in the Southeastern U.S. The study also examined whether students in each ability group were represented proportionately by gender, ethnicity, and SES when compared to the full sample. …

Environmental Sustainability, Cultural Awareness, And Personal Growth: A Short-Term Study Abroad Program Design For The University Of Colorado, Boulder, Jana K. Howlett

Capstone Collection

The University of Colorado (CU), as with many academic institutions in the United States, has seen a consistent increase in the number of students opting for short-term study abroad programs. A growing concern in the field of international education is whether it is possible for students to mature in cultural competence from such a short time spent abroad. In an initiative to deliberately increase students’ intercultural growth during short-term excursions, Global Seminar: Environmental Sustainability and Cross-Culture Contact in Costa Rica (GSCR) proposes a program that implements two new aspects to CU’s study abroad options: a course-linked program and an …

Metolachlor Metabolite (Mesa) Reveals Agricultural Nitrate-N Fate And Transport In Choptank River Watershed, Gregory Mccarty, Cathleen Hapeman, Clifford Rice, Dean Hively, Laura Mcconnell, Ali Sadeghi, Megan Lang, David Whitall, Krystyna Bialek, Peter Downey

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Over 50% of streams in the Chesapeake Bay watershed have been rated as poor or very poor based on the index of biological integrity. The Choptank River estuary, a Bay tributary on the eastern shore, is one such waterway, where corn and soybean production in upland areas of the watershed contribute significant loads of nutrients and sediment to streams. We adopted a novel approach utilizing the relationship between the concentration of nitrate-N and the stable, water-soluble herbicide degradation product MESA {2-[2-ethyl-N-(1- methoxypropan-2-yl)-6-methylanilino]-2-oxoethanesulfonic acid} to distinguish between dilution and denitrification effects on the stream concentration of nitrate-N in agricultural subwatersheds. The …

Rice (Oryza) Hemoglobins [Version 2; Peer Review: 2 Approved], Raúl Arredondo-Peter, Jose F. Moran, Gautam Sarath

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Hemoglobins (Hbs) corresponding to non-symbiotic (nsHb) and truncated (tHb) Hbs have been identified in rice (Oryza). This review discusses the major findings from the current studies on rice Hbs. At the molecular level, a family of the nshb genes, consisting of hb1, hb2, hb3, hb4 and hb5, and a single copy of the thb gene exist in Oryza sativa var. indica and O. sativa var. japonica, Hb transcripts coexist in rice organs and Hb polypeptides exist in rice embryonic and vegetative organs and in the cytoplasm of differentiating cells. At the structural level, the crystal …

Contribution Of Surface Leaf-Litter Breakdown And Forest Composition To Benthic Oxygen Demand And Ecosystem Respiration In A South Georgia Blackwater River, Andrew S. Mehring, Kevin A. Kuehn, Cynthia J. Tant, Catherine M. Pringle, R. Lowrance, George Vellidis

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Many North American blackwater rivers exhibit low dissolved O2 (DO) that may be the result of benthic respiration. We examined how tree species affected O2 demand via the quantity and quality of litter produced. In addition, we compared areal estimates of surface leaf-litter microbial respiration to sediment O2 demand (SOD) and ecosystem respiration (ER) in stream and swamp reaches of a blackwater river to quantify contributions of surface litter decomposition to O2 demand. Litter inputs averaged 917 and 678 g m−2 y−1 in the swamp and stream, respectively. Tree species differentially affected O2 demand via the quantity and quality of …

Hypena Opulenta (Erebidae): A European Species For The Biological Control Of Invasive Swallow-Worts (Vincetoxicum Spp.) In North America, Jim Young, Aaron S. Weed

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

The moth Hypena opulenta (Christoph, 1877) (Lepidoptera: Erebidae) was approved for release in eastern Canada and is pending approval in the United States of America as a biological control agent of the invasive European swallow-worts (Vincetoxicum spp.). Descriptions of the adult in Noctuidae Europeae do not accurately represent the color morph of the rearing colony so a new description is provided. Also for the first time the larva is described and illustrated and a simple key is provided that separates H. opulenta from most of the Hypena spp. in the Northeastern U.S.

Retrospective Examination Of Habitat Use By Blueback Herring (Alosa Aestivalis) Using Otolith Microchemical Methods, Molly Payne Wynne Ms

All Student Scholarship

Life histories of anadromous fish are difficult to examine due to constraints on direct observation. However, an understanding of patterns of habitat use is critical to management efforts since recruitment to spawning age is vital to population sustainability. Blueback herring (Alosa aestivalis) are anadromous fish that utilize a variety of freshwater, estuary and nearshore marine habitats. Rapid declines in their abundance and a subsequent petition for listing under the US Endangered Species Act in 2012 have ushered in an immediate need for life history information. This study focused on five river systems and seven spawning runs along the coast of …

Buyer Beware: What Is The Breakeven Value Of Beef Replacement Heifers?, Matthew Stockton, Kathleen Brooks, Roger K. Wilson

Cornhusker Economics

Each individual cow-calf producer will have a different answer to this question. The diversity of the results is inherent in the complexity of the question, which depends on a deceptively simple mathematical relationship. That relationship is known as the profit equation or function: profit is the difference between revenues and costs. This seems basic, as the only information one has to know is the revenues and costs associated with a particular animal. Once this is known, finding the value of that heifer can be mathematically computed. The complexity comes in determining answers to both the basic biological and economic questions. …

The Appeal Of Narrative In Research, Colette Daiute

Publications and Research

"I saw the bird flattened on the ground outside my door . One of the kindergarten child walked toward me slowly, crying. That's when I knew it was time to act."

The very brief narrative above occurs amid myriad spheres of social relations. These relations are not all apparent, but understanding narrative meaning requires understanding narrating as an interactive process. As researchers we enhance our Methods if we know how to read narratives as complex social processes. This openi11g narrative expresses a sequence of two past events.1 The narrative involves action ("walked," "act") and consciousness ("saw," "crying," "knew"). From the …

The Adaptation Of Native Language Construal Patterns In Second Language Acquisition, Loraine Obler, Eve Higby

Publications and Research

First language attrition occurs when a bilingual’s native language shows evidence of language change due to the predominant use of a second language. Recent research in first language attrition has shown that lexical retrieval and word choice are more vulnerable to reduced native language use than are grammatical constructions. However, some research has shown that grammar can also be affected, especially for constructions which exist in both languages but have different distributions in their usage. Taking concepts from cognitive linguistics, we attempt to describe how this research may provide insight into how language construal from the second language can affect …

A New Simple Method For Labeling Field Crops With Stable Isotope Tracers, Aaron J. Saathoff, Soundararajan Madhavan, Kenneth P. Vogel, Christian M. Tobias, Paul G. Twigg, Gautam Sarath

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Numerous systems have been used to label plants with ¹³C, which differ in design and complexity depending upon the desired experimental goals. However, most of these systems have generally been applied to greenhouse grown plants. Here, we report on a relatively simple ¹³C labeling system designed to label crops such as switchgrass (Panicum virgatum L.) grown in the greenhouse or small field plots. The main goals of this study were to validate the system and establish performance benchmarks. We constructed and field tested a simple design plexiglass chamber that was sealed at the soil level with a …

Spatiotemporal Characterization Of Sclerotinia Crown Rot Epidemics In Pyrethrum, Jason B. Scott, David H. Gent, Sarah J. Pethybridge, Frank S. Hay

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Sclerotinia crown rot, caused by Sclerotinia minor and S. sclerotiorum, is a disease of pyrethrum in Australia that may cause substantial decline in plant density. The spatiotemporal characteristics of the disease were quantified in 14 fields during three growing seasons. Fitting the binary power law to disease incidence provided slope (b = 1.063) and intercept (ln(A_p) = 0.669) estimates significantly (P ≤ 0.0001) greater than 1 and 0, respectively, indicating spatial aggregation at the sampling unit scale that was dependent upon disease incidence. Covariate analyses indicated that application of fungicides did not significantly influence these …

Microclimatic Performance Of A Free-Air Warming And Co2 Enrichment Experiment In Windy Wyoming, Usa, Daniel Lecain, David Smith, Jack Morgan, Bruce A. Kimball, Elise Pendall, Franco Miglietta

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

In order to plan for global changing climate experiments are being conducted in many countries, but few have monitored the effects of the climate change treatments (warming, elevated CO₂) on the experimental plot microclimate. During three years of an eight year study with year-round feedback-controlled infra-red heater warming (1.5/3.0°C day/night) and growing season free-air CO₂ enrichment (600 ppm) in the mixed-grass prairie of Wyoming, USA, we monitored soil, leaf, canopy-air, above-canopy-air temperatures and relative humidity of control and treated experimental plots and evaluated ecologically important temperature differentials. Leaves were warmed somewhat less than the target settings (1.1 …

Elevated Co2 Further Lengthens Growing Season Under Warming Conditions, Melissa Reyes-Fox, Heidi Steltzer, M. J. Trlica, Gregory S. Mcmaster, Allan A. Andales, Dan R. Lecain, Jack A. Morgan

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Observations of a longer growing season through earlier plant growth in temperate to polar regions have been thought to be a response to climate warming. However, data from experimental warming studies indicate that many species that initiate leaf growth and flowering earlier also reach seed maturation and senesce earlier, shortening their active and reproductive periods. A conceptual model to explain this apparent contradiction, and an analysis of the effect of elevated CO₂—which can delay annual life cycle events—on changing season length, have not been tested. Here we show that experimental warming in a temperate grassland led to a …

Litters Of Photosynthetically Divergent Grasses Exhibit Differential Metabolic Responses To Warming And Elevated Co2, Vidya Suseela, Daniella Triebwasser-Freese, Nora Linscheid, Jack A. Morgan, Nishanth Tharayil

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Climatic stress such as warming would alter physiological pathways in plants leading to changes in tissue chemistry. Elevated CO₂ could partly mitigate warming induced moisture stress, and the degree of this mitigation may vary with plant functional types. We studied the composition of structural and non-structural metabolites in senesced tissues of Bouteloua gracilis (C4) and Pascopyrum smithii (C3) at the Prairie Heating and CO₂ Enrichment experiment, Wyoming, USA. We hypothesized that P. smithii and B. gracilis would respond to unfavorable global change factors by producing structural metabolites and osmoregulatory compounds that are necessary to combat stress. However, due …

Long-Term Exposure To Elevated Co2 Enhances Plant Community Stability By Suppressing Dominant Plant Species In A Mixed-Grass Prairie, Tamara Jane Zelikova, Dana M. Blumenthal, David G. Williams, Lara Souza, Daniel R. Lecain, Jack Morgan, Elise Pendall

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Climate controls vegetation distribution across the globe, and some vegetation types are more vulnerable to climate change, whereas others are more resistant. Because resistance and resilience can influence ecosystem stability and determine how communities and ecosystems respond to climate change, we need to evaluate the potential for resistance as we predict future ecosystem function. In a mixed-grass prairie in the northern Great Plains, we used a large field experiment to test the effects of elevated CO₂, warming, and summer irrigation on plant community structure and productivity, linking changes in both to stability in plant community composition and biomass …

It's Complicated: Age, Gender, And Lifetime Discrimination Against Working Women - The United States And The U.K. As Examples, Susan Bisom-Rapp, Malcolm Sargeant

Faculty Scholarship

This article considers the effect on women of a lifetime of discrimination using material from both the U.S. and the U.K. Government reports in both countries make clear that women workers suffer from multiple disadvantages during their working lives, which result in significantly poorer outcomes in old age when compared to men. Indeed, the numbers are stark. In the U.S., for example, the poverty rate of women 65 years old and up is nearly double that of their male counterparts. Older women of color are especially disadvantaged. The situation in the U.K. is comparable.

To capture the phenomenon, the article …

The Separation Of Politics And Science, Joanna K. Sax

Faculty Scholarship

This article proposes that scientific inquiry regarding questions of fact should have an autonomous zone that is protected from politics. Although many scholars promote the idea that science is politicized, little empirical data exists to support this conclusion. This article contains an empirical study that demonstrates that the public received inaccurate information in the debate over a highly politicized and controversial area of scientific inquiry, embryonic stem cell research.

This article utilizes the data from the empirical study and public choice theory to explain that there are process defects; this economic model can help explain, but cannot be used to …

Marriage Equality Is Both Feminist And Progressive, Barbara Cox

Faculty Scholarship

Marriage equality has the ability to lessen vulnerability for society’s most needy. This article discusses two aspects of marriage equality in particular. Part II discusses why marriage equality can be feminist in practice and why obtaining marriage equality for same-sex couples will advance feminist values within marriage. Part III discusses how marriage equality can be progressive and help those who are vulnerable in our society by providing numerous rights that are otherwise unavailable or expensive to replicate. While marriage equality cannot bring an end to the many problems caused by marriage’s privileged status in our society, it has the ability …
