Effect Of Exogenous Enzymes On Apparent Metabolizable Energy Value Of Barley In Swine And Broiler Chickens, Brian L. Bryson

Theses and Dissertations--Animal and Food Sciences

The objective of this thesis was to evaluate the effect of exogenous enzyme supplementation, phytase and xylanase-glucanase, on AME value of barley in poultry and swine. In the first study, 280 broilers were assigned 1 of 8 treatments. Barley inclusion in the diet resulted in decreased (P < 0.05) performance. There was a treatment × phytase × xylanase-glucanase interaction for dry matter retention with birds fed the corn-SBM-barley diet supplemented with phytase and xylanase-glucanase having higher (P < 0.05) DM retention compared to birds fed corn-SBM-based diet with only xylanase-glucanase supplementation. AME and AMEn of corn-SBM-based diets were greater (P < 0.05) than the corn-SBM-barley-based diets. Energy metabolizability and AMEn of barley significantly increased with xylanase-glucanase supplementation. In the second study, 24 pigs (12 pigs/phase) were assigned to 1 of 4 treatments with xylanase-glucanase and phytase. After a 7-d adaption period, urine and feces were quantitatively collected for 5 d. DE of the barley-based diet supplemented with xylanase-glucanase (3,578 kcal/kg) and phytase and xylanase-glucanase in combination (3,617 kcal/kg) were significantly different. Compared to control diets, exogenous enzymes either significantly improved or had a tendency to improve AME and AMEn value of barley in broilers, but not in growing pigs.

Compost Bedded Pack Dairy Housing: Animal Performance And Well-Being And Economic Viability In A Pasture-Based System, Betty Kawonga

Theses and Dissertations--Animal and Food Sciences

Improving housing for dairy cattle is of interest because hoof and udder health, which are associated with the housing environment, are important economic and welfare issues. The objectives were: 1) to assess the influence of housing––conventional cubicle (CCD) vs compost bedded pack (CBP),––and management (grazing vs semi-grazing) on the performance and welfare in dairy cows 2) describe the performance of the CBP under a grazing or semi-grazing system, and 3) to assess viability of CBP housing in a pasture-based system. This study mixes three research approaches, an analysis of existing and secondary data; an experiment, and a case-study. If taken …

Evaluating The Relationship Between Physician Characteristics And Opioid Knowledge And Use Of Opioid And Non-Opioid Chronic Pain Management Strategies, Erin Hopkins Stern

PCOM Psychology Dissertations

Opioid use disorder (OUD) is a mental health condition that has high personal, societal, and emotional costs. Opioid use disorder, misuse, and abuse is a national epidemic. Many factors have contributed to the increased use of opioids and OUD. One such factor is the heightened emphasis on pain management in the medical community, one that that began nearly two decades ago. This has led to increased prescribing of opioid-based medication for chronic pain patients. This contributed in part to the development of OUD in many individuals who became addicted to opioids. For this reason, current guidelines discourage the use of …

Fourth Amendment Anxiety, Kiel Brennan-Marquez, Stephen E. Henderson

Faculty Articles and Papers

In Birchfield v. North Dakota (2016), the Supreme Court broke new Fourth Amendment ground by establishing that law enforcement's collection of informa­tion can be cause for "anxiety," meriting constitutional protection, even if subsequent uses of the information are tightly restricted. This change is significant. While the Court has long recognized the reality that police cannot always be trusted to follow constitutional rules, Birchfield changes how that concern is implemented in Fourth Amendment law, and importantly, in a manner that acknowledges the new realities of data-driven policing.

Beyond offering a careful reading of Birchfield, this Article has two goals. First, …

Description Of A New Sound Produced By Nassau Grouper At Spawning Aggregation Sites, Timothy J. Rowell, Michelle T. Schärer, Richard S. Appeldoorn

Gulf and Caribbean Research

This study identified a new sound produced by Nassau Grouper in association with, although potentially not exclusive to, an agonistic interaction at a spawning aggregation. We have also provided a behavioral and acoustic description for identification of this sound in future studies. The discovery of a third type of sound produced by Nassau Grouper further highlights the importance of acoustic communication coupled with visual displays in fishes. Furthermore, identification of a new sound increases the ability to document the presence of this endangered species at spawning sites. Future efforts may reveal that the sound is produced within additional behavioral contexts …

Diel Activity Patterns And Movement Of Invasive Lionfish (Pterois Volitans/P. Miles) In The Florida Keys Identified Using Acoustic Telemetry, Michael Mccallister, Jeffrey Renchen, Benjamin Binder, Alejandro Acosta

Gulf and Caribbean Research

The invasion of Indo—Pacific lionfish (Pterois volitans/P. miles) throughout the Caribbean and southeastern U.S. Atlantic represents a significant ecological threat, yet few studies have examined the daily activity and movement patterns of this invasive species. In this study, passive acoustic telemetry was used to track lionfish at 4 coral reef sites in the Florida Keys. Fourteen lionfish were tagged among the 4 sites, and the total number of days tagged fish were detected ranged from 5 to 141 days. Hourly detection data revealed diel activity patterns with peaks at dawn and dusk. Mixed model analysis of detection data indicated a …

Effectiveness Of Drafting Models For Engineering Technology Students And Impacts On Spatial Visualization Ability: An Analysis And Consideration Of Critical Variables, Petros J. Katsioloudis, Jill E. Stefaniak

STEMPS Faculty Publications

Results from a number of studies indicate that the use of drafting models can positively influence the spatial visualization ability for engineering technology students. However, additional variables such as light, temperature, motion and color can play an important role but research provides inconsistent results. Considering this, a set of 5 quasi-experimental studies, was conducted to identify additional critical variables. According to the results, a dynamic, 3Dprinted drafting model, presented with a blue background under lighting conditions between 500–750 lux had the highest impact on spatial visualization ability of engineering technology students.

Natural History Of The Southern Bog Lemming In Southeastern Virginia, Robert K. Rose

Biological Sciences Faculty Publications

The isolated subspecies of Southern Bog Lemming of southeastern Virginia, Synaptomys cooperi helaletes, has been studied extensively since its "rediscovery" in the Great Dismal Swamp in 1980. Multiple studies using pitfall traps, starting in the Great Dismal Swamp National Wildlife Refuge and then extending elsewhere in southeastern Virginia and adjacent northeastern North Carolina, have revealed lemmings to be much more widespread and often more common than previously believed, with their presence now confirmed as far west as Surry and Sussex counties, about 30 km east of Petersburg, Virginia. When present, lemmings often are among the most numerous members of …

Human–Black Bear Conflicts: A Review Of Common Management Practices, Carl W. Lackey, Stewart W. Breck, Brian F. Wakeling, H. Bryant White

Human–Wildlife Interactions Monographs

The objective of this monograph is to provide wildlife professionals, who respond to human–bear conflicts, with an appraisal of the most common techniques used for mitigating conflicts as well as the benefits and challenges of each technique in a single document. Most human–black bear conflict occurs when people make anthropogenic foods like garbage, dog food, domestic poultry, or fruit trees available to bears. Bears change their behavior to take advantage of these resources and may damage property or cause public safety concerns in the process. Managers and the public need to understand the available tools to stop human–bear conflict and …

Plant Community Response To Disturbances In Nebraska Sandhills Upland Prairie, Josiah D. Dallmann

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

Historically, disturbances shaped prairie ecosystems both directly through events like fire and soil moving by animals, as well as indirectly through dynamic rainfall patterns and periodic flux in seed availabilities. We hypothesized that the implementation of several distinct disturbance events in Nebraska Sandhills upland prairie would have measurable effects on plant community composition. We implemented mid-spring fire, soil disturbance in the form of disking, seed addition of native forbs on disked plots, as well as early summer supplemental watering (to mimic minor rainfall events during abnormally dry periods) during 2016 and 2017. Plant community response during the first and second …

School of Education Faculty Publications

This study explored the relationship between preschoolers’ exposure to Daniel Tiger’s Neighborhood television programming and its accompanying mobile app and preschoolers’ emotion knowledge and use of emotion regulation strategies. An experiment involving 121 parent-child dyads from 3 US metro areas found that children who played with the Daniel Tiger’s Neighborhood app, and those who both played with the app and watched episodes of the program, employed the emotion regulation strategies taught by Daniel Tiger’s Neighborhood media more frequently 1 month later than children in a control condition. Preschoolers (3- and 4-year-olds) also exhibited higher levels of emotion knowledge 1 month …

Colonization Of And Adaptation To Tidal Marshes In The Savannah Sparrow (Passerculus Sandwichensis), Phred M. Benham

Graduate Student Theses, Dissertations, & Professional Papers

Intraspecific patterns of geographic variation reflect a dynamic history of colonization and divergence in response to spatially varying selective pressures. Analysis of this phenotypic variation has long stimulated biological thought, yet many outstanding questions remain regarding the ecological and evolutionary mechanisms driving patterns of geographic variation. In my dissertation, I collected data on demographic history, physiological traits contributing to salinity tolerance, and acclimation responses to different salinities to elucidate the mechanisms shaping colonization and adaptive divergence in tidal marsh populations of Savannah Sparrows (Passerculus sandwichensis). Specifically, I addressed two main questions related to adaptive divergence in this species: (1) how …

Home Is Where The Food Is: Causes And Consequences Of Partial Migration In Elk, Kristin Jennifer Barker

Graduate Student Theses, Dissertations, & Professional Papers

Migratory and non-migratory ungulates often coexist in partially migratory populations, but the mechanisms that drive and maintain different migratory behaviors within the same herd are poorly understood. In western North America, increasing numbers of elk (Cervus canadensis) reside on low-elevation winter range year-round. These residents can cause issues associated with crop damage, potential for disease transmission to livestock, and reduced effectiveness of harvest management strategies. Because migrants transfer nutrients, alter carnivore distributions, and structure vegetative communities across seasonal ranges, reductions in migratory behavior raise ecological as well as management-related concerns. This work investigated the factors affecting migratory behavior …

A Cartographic Workflow Manual For Endangered Species Conservation, Martin P. Viereckl

Graduate Student Theses, Dissertations, & Professional Papers

In response to global consumer demand for rare and exotic wildlife products, poaching of endangered species has become pervasive around the world (Eliason 1999). Despite the enactment of CITES, and other international efforts to protect vulnerable species from overexploitation, the global market for illegal wildlife products is estimated as high as $20-billion a year industry (Wyler 2008). Within important wildlife habitat sites, law enforcement struggle to curb rampant poaching that threatens the ultimate survival of many endangered species (Jachmann 2008; Rowcliffe 2004). Law-enforcement agencies responsible for protecting wildlife from poachers often lack geospatial tools that could greatly improve the effectiveness …

Midwifery Anatomized: Vesalius, Dissection, And Reproductive Authority In Early Modern Italy, Jennifer Kosmin

Faculty Journal Articles

Although Vesalius, like his contemporaries, had only extremely limited opportunities to examine or dissect the human gravid uterus, it is the image of the anatomist laying bare the (un)pregnant female body and revealing its secrets that graces the title page of the 1543 edition of De humani corporis fabrica. This essay focuses on the implications of Vesalius’s and his followers’ anatomical discoveries for the practice and professional status of early modern Italian midwives. In particular, the essay focuses on three venues in which the authority to understand the female body and the processes of reproduction were contested. A close …

A Dynamic Ocean Management Tool To Reduce Bycatch And Support Sustainable Fisheries, Elliot L. Hazen, Kylie L. Scales, Sara M. Maxwell, Dana K. Briscoe, Heather Welch, Steven J. Bograd, Helen Bailey, Scott R. Benson, Tomo Eguchi, Heidi Dewar

Biological Sciences Faculty Publications

Seafood is anessential sourceofprotein formore than3billionpeopleworldwide, yet bycatchof threatened species in capture fisheries remains a major impediment to fisheries sustainability. Management measures designed to reduce bycatch often result in significant economic losses and even fisheries closures. Static spatial management approaches can also be rendered ineffective by environmental variability and climate change, as productive habitats shift and introduce new interactions between human activities and protected species. We introduce a new multispecies and dynamic approach that uses daily satellite data to track ocean features and aligns scales of management, species movement, and fisheries. To accomplish this, we create species distribution models for …

Spectators, Sponsors, Or World Travelers? Engaging With Personal Narratives Of Others Through The Afghan Women's Writing Project, Bethany Mannon

English Faculty Publications

This article studies the Afghan Women’s Writing Project and proposes three conceptual tools for examining the ways readers and editors of digital storytelling projects interact with writers and texts. The author advances discussions of personal narrative and the role this form of writing plays in transnational feminism and forms of humanitarian activism that increasingly take place online. Digital storytelling projects effectively circulate these personal accounts, but they benefit from scholarship that advises self-critical approaches to representing their subjects.

Dialogical Numbers: Counting Humanimal Pain In J.M. Coetzee's Elizabeth Costello, Mike Piero

English Faculty Publications

This essay argues that J.M. Coetzee's Elizabeth Costello stages numerical sequences strategically, dialogically, and parodically in order to call attention to the ideological weight involved in counting. Focusing on how one counts - and accounts for - human and nonhuman animal pain, I contend that the repetition of numbers in the novel works to subvert the neoliberal faith put in numbers, quantification, and data. Without succumbing to some religious-mystical numerology, this reading attempts to expose the fiction involved in the act of counting and the need to pay more attention to numerical discourse in literary fiction. In tracking these numbers …

The Mechanisms Shaping The Repertoire Of Cd4(+)Foxp3(+) Regulatory T Cells, Piotr Kraj, Leszek Ignatowicz

Biological Sciences Faculty Publications

Regulatory T (Treg) cells expressing Foxp3 transcription factor control homeostasis of the immune system, antigenic responses to commensal and pathogenic microbiota, and immune responses to self and tumour antigens. The Treg cells differentiate in the thymus, along with conventional CD4⁺ T cells, in processes of positive and negative selection. Another class of Treg cells is generated in peripheral tissues by inducing Foxp3 expression in conventional CD4⁺ T cells in response to antigenic stimulation. Both thymic and peripheral generation of Treg cells depends on recognition of peptide/MHC ligands by the T-cell receptors (TCR) expressed on thymic Treg precursors or …

Characterizing Habitat Suitability For A Central‐Place Forager In A Dynamic Marine Environment, Dana K. Briscoe, Sabrina Fossette, Kylie L. Scales, Elliott L. Hazen, Steven J. Bograd, Sara M. Maxwell, Elizabeth A. Mchuon, Patrick W. Robibson, Carey Kuhn, Daniel P. Costa, Larry B. Crowder, Rebecca L. Lewison

Biological Sciences Faculty Publications

Characterizing habitat suitability for a marine predator requires an understanding of the environmental heterogeneity and variability over the range in which a population moves during a particular life cycle. Female California sea lions (Zalophus californianus) are central‐place foragers and are particularly constrained while provisioning their young. During this time, habitat selection is a function of prey availability and proximity to the rookery, which has important implications for reproductive and population success. We explore how lactating females may select habitat and respond to environmental variability over broad spatial and temporal scales within the California Current System. We combine near‐real‐time …

Quotidian Intimidation And Mussolini's Special Tribunal In Istria And The Eastern Borderlands, Maura Hametz

History Faculty Publications

The article examines the Special Tribunal for the Defense of the State's use of the "no grounds to proceed" ruling to intimidate anti-fascists and extend the fascist government's power in the Adriatic borderlands. It demonstrates how the Tribunal's judges used their sentencing prerogatives to support repression in Istria and cloak persecution in the mantel of legal action in defense of the state.

Plastid Dna Variation Of The Endemic Species Oxytropis Glandulosa Turcz. (Fabaceae), Alla Kholina, Marina Kozyrenko, Elena Artyukova, Denis Sandanov, Inessa Selyutina, Daba Chimitov

Turkish Journal of Botany

Oxytropis glandulosa Turcz. (Fabaceae) is a rare perennial plant endemic to Buryatia (Russia). We sequenced three intergenic spacers (the psbA−trnH, trnL−trnF, and trnS−trnG) of chloroplast DNA (cpDNA) in specimens of four populations from two geographic regions (Barguzin and Yeravna depressions) within this species range. The levels of haplotype and nucleotide diversity varied in the range of 0.133−0.911 and 0.0002−0.0059, respectively. The highest values of these parameters are characteristic of populations located in the Barguzin depression. Variable sites detected within the intergenic spacers allowed the identification of eleven haplotypes; nine of them were found in the populations from the Barguzin depression …
