Using The Judas Technique To Locate And Remove Wintertime Aggregations Of Invasive Common Carp, P. G. Bajer, Christopher J. Chizinski, P. W. Sorensen

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

Radio- and acoustic telemetry in three Midwestern lakes demonstrated that common carp, Cyprinus carpio L., aggregate as water temperatures descend below 10C. Particularly dense aggregations formed at temperatures <5 >C, and once located, these aggregations could be removed with an efficiency of up to 94% using seine nets. Carp aggregated just below the surface of the ice (approximately 1.5 m) and rarely descended to warmer waters, which extended down to 10 m. Although aggregations consistently formed close to shore, their locations could not be explained by temperature or dissolved oxygen. The aggregations also moved frequently, making radio-tagged fish invaluable to locate …

Mixed-Source Reintroductions Lead To Outbreeding Depression In Second-Generation Descendents Of A Native North American Fish, David D. Huff, Loren M. Miller, Christopher J. Chizinski, Bruce Vondracek

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

Reintroductions are commonly employed to preserve intraspecific biodiversity in fragmented landscapes. However, reintroduced populations are frequently smaller and more geographically isolated than native populations. Mixing genetically, divergent sources are often proposed to attenuate potentially low genetic diversity in reintroduced populations that may result from small effective population sizes. However, a possible negative tradeoff for mixing sources is outbreeding depression in hybrid offspring. We examined the consequences of mixed-source reintroductions on several fitness surrogates at nine slimy sculpin (Cottus cognatus) reintroduction sites in south-east Minnesota. We inferred the relative fitness of each crosstype in the reintroduced populations by comparing …

Breeding Bird Response To Partially Harvested Riparian Management Zones, Christopher J. Chizinski, Anna Peterson, Joann Hanowski, Charles R. Blinn, Bruce Vondracek, Gerald J. Niemi

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

We compared avian communities among three timber harvesting treatments in 45-m wide even-age riparian management zones (RMZs) placed between upland clearcuts and along one side of first- or second-order streams in northern Minnesota, USA. The RMZs had three treatments: (1) unharvested, (2) intermediate residual basal area (RBA) (targeted goal 11.5m²/ha, realized 16.0m2/ha), and (3) low RBA (targeted goal 5.7m²/ha, realized 8.7m²/ha). Surveys were conducted one year pre-harvest and three consecutive years post-harvest. There was no change in species richness, diversity, or total abundance associated with harvest but there were shifts in the types of …

Explaining Spatial Variability In Stream Habitats Using Both Natural And Management-Influenced Landscape Predictors, K. J. Anlauf, D. W. Jensen, K. M. Burnett, E. A. Steel, K. Christiansen, J. C. Firman, B. E. Feist, D. P. Larsen

United States Department of Commerce: Staff Publications

1. The distribution and composition of in-stream habitats are reflections of landscape scale geomorphic and climatic controls. Correspondingly, Pacific salmon (Oncorhynchus spp.) are largely adapted to and constrained by the quality and complexity of those in-stream habitat conditions. The degree to which lands have been fragmented and managed can disrupt these patterns and affect overall habitat availability and quality.

2. Eleven in-stream habitat features were modelled as a function of landscape composition. In total, 121 stream reaches within coastal catchments of Oregon were modelled. For each habitat feature, three linear regression models were applied in sequence; final models were …

A Combined Visual And Acoustic Estimate Of 2008 Abundance, And Change In Abundance Since 1997, For The Vaquita, Phocoena Sinus, Tim Gerrodette, Barbara L. Taylor, René Swift, Shannon Rankin, Armando M. Jaramillo-Legorreta, Lorenzo Rojas-Bracho

United States Department of Commerce: Staff Publications

A line-transect survey for the critically endangered vaquita, Phocoena sinus, was carried out in October–November 2008, in the northern Gulf of California,Mexico. Areas with deeper water were sampled visually from a large research vessel, while shallow water areas were covered by a sailboat towing an acoustic array. Total vaquita abundance in 2008 was estimated to be 245 animals (CV = 73%, 95% CI 68– 884). The 2008 estimate was 57% lower than the 1997 estimate, an average rate of decline of 7.6%/yr. Bayesian analyses found an 89% probability of decline in total population size during the 11 yr period, …

Can Evidence For Spatial And/Or Temporal Genetic Heterogeneity Of North Pacific Minke Whales Be Explained By Different Mixture Fractions Of The Same Two Core Stocks, Or Is It Necessary To Postulate An Additional Stock (S)?, Robin Waples

United States Department of Commerce: Staff Publications

The analyses described here take advantage of the specificity of the two-stock mixing hypothesis for North Pacific common minke whales, which leads to some testable hypotheses based on standard population genetics theory. If the hypothesis is true (heterogeneity can be explained by different mixture fractions of the same two stocks, O and J, in different areas), loci with the largest allele frequency differences between J and O stock should show the largest departures from equilibrium when mixed samples are analyzed. Allele frequency differences were characterized by θ, an analogue of F_ST, and departures from equilibrium were indexed by …

Dispute Resolution & New Governance: Role Of The Corporate Apology, Michael B. Runnels

Seattle University Law Review

In the wake of the Great Recession, there is greater public expectation to see corporations express proper contrition for their errors. While corporate leaders and myriad stakeholders acknowledge that corporations ought to be more responsive to public expectations of ethical corporate behavior, the modern corporate social responsibility (CSR) movement is simply unequipped to incentivize this behavior. This unresponsiveness can be seen in the area of dispute resolution between corporations and individuals. While the argument may seem counter-intuitive on first impression, the use of corporate apologies is both good business and good ethics. While there is minimal overlap in the dispute …

H. T. Tsiang: Literary Innovator And Activist, Floyd Cheung

English Language and Literature: Faculty Publications

A Chinese exile in the United States, H. T. Tsiang (1899-1971) wrote several books in English that represent pioneer works in the canon of Asian American literature. Following the principle of nalai zhuyi, or strategic appropriation from other writers, Tsiang created a new, hybridized literature by reworking formal and thematic elements from classical and contemporary Chinese literature, the proletarian works of 1920s and 1930s America, and western classics like the plays of William Shakespeare. Although few know his work today, Tsiang is one of the earliest and most prolific innovators of Asian American literature, anticipating some of the appropriative methods, …

The Birds Of Chichaqua Bottoms Greenbelt (Polk County, Iowa): Patterns Of Habitat Use And Implications For Management, Keith Summerville, Joel Boyles, Loren Lown

Journal of the Iowa Academy of Science: JIAS

Despite the fact that many birds are believed to be declining as a result of habitat loss and elimination of historic disturbance regimes, few studies have explored how restoration and management of mixed grassland and woodland systems influence bird communities. In this study, we tested whether habitat size, habitat type, and use of prescribed fire as a management tool affected the species richness and composition of bird communities sampled from 22 restored grassland and woodland sites within Chichaqua Bottoms Greenbelt (Polk County, Iowa). In 2004-5 bird communities were sampled by walking transects within each site and recording the presence and …

Functional Hak/Kup/Kt-Like Potassium Transporter Encoded By Chlorella Viruses, Timo Greiner, José Ramos, Maria C. Alvarez, James Gurnon, Ming Kang, James L. Van Etten, Anna Moroni, Gerhard Thiel

James Van Etten Publications

Chlorella viruses are a source of interesting membrane transport proteins. Here we examine a putative K+ transporter encoded by virus FR483 and related chlorella viruses. The protein shares sequence and structural features with HAK/KUP/KT-like K+ transporters from plants, bacteria and fungi. Yeast complementation assays and Rb+ uptake experiments show that the viral protein, termed HAKCV (high-affinity K+ transporter of chlorella virus), is functional, with transport characteristics that are similar to those of known K+ transporters. Expression studies revealed that the protein is expressed as an early gene during viral replication, and proteomics data indicate that it is not packaged in …

The Comparability Of Bioassessments: A Review Of Conceptual And Methodological Issues, Y. Cao, Charles P. Hawkins

Watershed Sciences Faculty Publications

Differences in the raw data used in bioassessments and choices regarding how those data are analyzed and summarized can affect inferences regarding the status of ecological resources and, thus, the degree to which we can trust individual ecological assessments, compare assessments across different programs and regions, or share data when developing or refining new endpoint indices. Progress in addressing these issues has been hindered by lack of consensus regarding what a general definition of comparability should be in the context of bioassessments and what measures of comparability are appropriate for ecological data. In this paper, we review the state of …

Executive Control And Dimensions Of Problem Behaviors In Preschool Children, Kimberly A. Espy, Tiffany Sheffield, Sandra A. Wiebe, Caron A. C. Clark, Matthew J. Moehr

Developmental Cognitive Neuroscience Laboratory: Faculty Publications

Background: Despite the widespread recognition of the importance of executive control (EC) in externalizing psychopathology, the relation between EC and problem behavior has not been well characterized, particularly in typically developing preschoolers.
Method: Using the sample, battery of laboratory tasks, and latent variable modeling methods described in Wiebe, Espy, and Charak (2008), systematic latent dimensions of parent-rated problem behavior, measured by integrating scales from developmental and clinical traditions, were determined empirically, and then were related to EC.
Results: Substantial relations between EC and problem behaviors were revealed by extracting the common variance of interest and eliminating extraneous variance, which were …

Measuring Scholarly Metrics, Gordon R. Mitchell, Scott Church, Travis Bartosh, Getachew Dinku Godana, Rachel Stohr, Sarah Jones, Adam Knowlton

Department of Communication Studies: Faculty Publications

The following chapters explore six contemporary metrics of scholarly authority (Journal Impact Factor, Web of Science citations, h-index, SCImago, article download usage data, university press book publication), considering each metric’s strengths and weaknesses as measurement tools, and speculating on the consequences their widespread utilization of each might mean for the field of Communication, the academy, and society. Leaving the task of a systematic meta-analysis of scholarly metrics for another day, this report instead is designed to work as an entry point for readers interested in how the advent of new digital measurement tools carry potential to compete with traditional gold …

Improving Urban Ecology Bringing Native Back Home, Leo Ferretti

Theses & ETDs

The urban environment is the new frontier for ecological improvement. Urban planting creates a richer ecosystem, enhances biodiversity, improves mental health, and alleviates some of the environmental externalities generated by urban areas (including pollution, runoff and heat island effects). This thesis examines the importance of improving city ecology and explores strategies by which to enact these improvements. Today, new measures-- such as restoration, reforestation, reconciliation and building green roofs-- must be taken to foster urban biodiversity. Developers often overlook the advantages of well-rounded planting programs due to their cost, but education can reverse this trend. Urban environmental research suggests that …

Rage Against The Form Resisiting Oppressive Gender Identity In The Work Of Carson Mccullers, Toni Morrison And Jeffrey Eugenides, Chelsee Payne

Theses & ETDs

The thesis investigates specific ideas of gendered identity in three separate periods and three separate regions in the United States. It focuses on the way gendered identity is imagined and resisted in Carson McCullers�s The Ballad of Sad Caf�, Toni Morrison�s The Bluest Eye and Jeffrey Eugenides�s Middlesex. I analyze how these concepts are created and enforced in society and through literary forms. Chapter one examines Carson McCullers�s play with the Southern female ideal, circa mid-twentieth century and her rewriting of the �ballad� form. McCullers complicates the binary between �masculine� and �feminine� in the character of Miss Amelia. Chapter two …

Pay Attention To Biophilia It's In The Flow, Ashley King

Theses & ETDs

This study sought to explore the possible relationship between two theories addressing psychological health: Wilson�s Biophilia Hypothesis and Csikszentmihalyi�s Flow. Undergraduate college students played Tetris before viewing either a nature video or a built environment video. After the video, participants completed another game of Tetris and a shortened version of the Flow State Scale. It was hypothesized that contact with nature would restore attention capacity and facilitate the flow experience, leading to a higher level of improvement from pre-test to post-test and also higher scores on the FSS in the nature condition than in the built environment condition. As expected, …

Exogenous Expression Of Dna Pilot Protein H With Mutated Colied-Coil Domains Inhibits Bacteriophage ?X174, Lindsey Young

Theses & ETDs

The DNA pilot protein H of bacteriophage ?X174 is known to pilot the viral genome into the host organism, Escherichia coli. Recent evidence suggests the DNA pilot protein is also involved in protein biosynthesis. Though the structure of the DNA pilot protein is unknown, it is predicted by bioinformatics to have an N-terminal domain, four coiled-coil domains, and two DNA binding sites. The sequence of the DNA pilot protein was cloned with mutations that disrupted coils 1 and 4 of the protein. Another set of mutants contained an N-terminal deletion starting at residue 142 in addition to the mutations that …

Everglades Ecology Restoration Inspiring Science Education, Angelique Giraud

Theses & ETDs

The incorporation of environmental issues into classroom science education improves salience for students. Understanding scienceraises the quality of life for individual citizens and strengthens the U.S. as a whole (Augustine 2010). The sustainability of the earth is threatened by current habits and requires positive change through innovation and a common conscience. The concern for Everglades� ecology highlights this. A case study presented important scientific concepts through a focus on the Everglades to high school students in Sarasota. Data analyzed from student�s scores on a pre- and post-quiz were significant. This indicated that the methods used and discussed were successful and …

Candy Land, Brittney Champagne

Theses & ETDs

Sweetness functions as a symbolic prop for human desire. My artwork questions the cost of this desire, troubling what can and should be consumed, while negotiating the environmental and social histories of human desire for sugar. This project generates a subjective history for the strange, perhaps unnatural, commodities that people desire, through which I aim to plant them more firmly into the natural world from which they have been separated by so much plastic, foil, and ornament.

Olfactory Communication And Indivdual Recognition In Eulemur Mongoz, The Mongoose Lemur, Katherine Smith

Theses & ETDs

Olfactory communication is a major aspect in lemur biology and behavior. Since it was first studied, research and experiments have focused on Lemur catta, the ring-tailed lemur. The purpose of this thesis was to begin to bridge the information gap that existed between L. catta and most other lemurs, by trying to determine whether Eulemur mongoz, the mongoose lemur, could distinguish between individuals based solely on olfactory communication. A habituation/dishabituation experiment was done using a total of eight E. mongoz from the Lemur Conservation Foundation in Myakka City, Florida. Pads that were marked with a conspecific�s scent were presented in …

Songs Of The Mountains, Songs Of Resistance A Study Of Protest Music Against "King Coal" In Southern Appalachia, Historically And Today, Sara Henry

Theses & ETDs

The focus of this project has been compiling a collection of music about mountaintop removal coal mining and the history of coal mining in Southern Appalachia. The songs are ballads, folk, bluegrass, and old time songs of the past and present. Some songs already focused on this important environmental and social justice issue, and others were changed lyrically to encompass this subject. The practice of changing lyrics to suit a new cause has been common in the history of folk music in America. For example, in Mark Allan Jackson�s Prophet Singer, he spends part of a chapter outlining the ways …

Perspective, Heather Mullins

Theses & ETDs

My still life paintings act as a metaphor for the way mankind relates to reality, by containing and distorting it. The glass jars in these paintings obscure the view of their surrounding objects, representing the way we alter reality through the lens of perspective, which I use in terms of a mental view rather than a spatial relationship. This thesis draws on Normon Bryson�s theories in Looking at the Overlooked, as well as the practices of artists Audrey Flack and Janet Fish to support my attempt at illustrating the subjectivity in how we view the world. My goal is to …

Making Sense Of Feeling An Interdisciplinary Exploration Of William James' Theory Of Emotion, Jeremy Axelrad

Theses & ETDs

First published in 1884, William James� theory of emotion identifies emotional feelings with the body�s perception of its own living in the world. Though James� theory stands as a well-known landmark in the study of emotion, it is often taken out of the larger context of his attentive investigations of subjective experience. This thesis integrates James� writings on the topics of the body, consciousness, and value to propose a vision of the mind that is thoroughly affective, embodied, and organic, dynamically relating to a world of lived-through meanings as a unified whole. This understanding finds strong convergent support from current …

In Defense Of Jewish Manhood Monotheism, Circumcision, And Gender In Freud�S Construction Of Jewish Identity, Jeremy Zorn

Theses & ETDs

This thesis argues that the parallel discourses Freud develops surrounding monotheism and circumcision, in Moses and Monotheism, seek to overcome anti-Semitic perceptions of Jewish effeminacy�perceptions which Freud, himself, internalized to a great extent. While Freud�s treatment of monotheism demonstrates his belief in an essential Jewish affinity for male-coded spirituality over female-coded sensuality, his understanding of circumcision proves to be more problematic. Having established the theoretical connection of circumcision, castration, and effeminacy in a prior work, Freud attempts to reconfigure the meaning of circumcision in Moses and Monotheism. Despite his effort to unite his theory of circumcision with his idealization of …
