Predicting Mountain Lion Resource Selection And Abundance In North America, William Connor O'Malley

Graduate Student Theses, Dissertations, & Professional Papers

The relationship between habitat quality and density is well documented in lower trophic levels but to what extent it can be extended to higher trophic levels is unknown. I tested the relationship between habitat quality, home-range size and density using a wide-ranging, well-studied, top carnivore, the mountain lion (Puma concolor). First, I created a second-order resource selection function (RSF) for mountain lions in their current North American range using GPS collar data from 476 individuals in 20 study sites and remotely-sensed landscape data. I used the RSF and home range estimates derived from collared animals to quantify mountain …

Inhumanity Restored: Digital Play & Poetic Drama, Ali Emir Dağlar

Comparative Literature M.A. Essays

This essay addresses the relationship of digital games to absurdism through a comparison of the 2011 video game Dark Souls with Samuel Beckett’s absurdist play Waiting for Godot. Staked in this comparison is the rhetoric not only of Dark Souls but of the contemporary digital game as a medium; establishing an analogy that speaks to the broader genealogy of modern media, my argument implicates the underemphasized yet critically meaningful kinship of computer games and poetic theater. I argue that understanding the digital game vis-a-vis absurdism means explicating how the 20th century stage, particularly that of Beckett, prefigures contemporary digital worlds …

From Nihilation To Redemption: Profanations And Overlaps In Claudio Magris’ Danube, Nicola Mazzotti

Comparative Literature M.A. Essays

This essay analyzes the novel Danube by the Italian writer and scholar Claudio Magris and focuses on its depiction of the political potential inscribed in the Danubian territory. With his journey along the river, the narrator of the novel attempts to unveil the materiality of this territory and the agency of the river, thus deconstructing cultural and political claims aimed at their appropriation. First, the essay investigates the use and representation of 'sources' made by the narrator, both as origin of the river and cultural artifacts. It is shown how the narrator performatively traces the origin of the river back …

Situated Data: Feminist Epistemology And Data Curation, Scout Calvert

University of Nebraska-Lincoln Libraries: Faculty Publications

In the last decade or more, academic libraries have taken up the challenge of providing data curation and research data support, bringing expertise in metadata and digital preservation to key aspects of the research data life cycle. This activity has hastened since 2013, when the White House Office of Science and Technology Policy (OSTP) issued a memo directing federal funding agencies to require data, among other products of research, to be shared as a condition of funding.1 The OSTP memo did not come out of the blue, but recognized changes in data practice in some disciplines as the costs of …

Ethical Design Of Computers: From Semiconductors To Iot And Artificial Intelligence, Sudeep Pasricha, Marilyn Wolf

School of Computing: Faculty Publications

Computing systems are tightly integrated today into our professional, social, and private lives. An important consequence of this growing ubiquity of computing is that it can have significant ethical implications of which computing professionals should take account. In most real-world scenarios, it is not immediately obvious how particular technical choices during the design and use of computing systems could be viewed from an ethical perspective. This article provides a perspective on the ethical challenges within semiconductor chip design, IoT applications, and the increasing use of artificial intelligence in the design processes, tools, and hardware-software stacks of these systems.

Creative Connections: A Guidebook For Arts-Based Inquiry, Julia Marshall, Kimberley D'Adamo, Ann Ledo Lane

Kimberley D'Adamo: Art, Curriculum, Publications, and Other Scholarly Works

Art-based inquiry is an approach to art education that frames art making as a form of inquiry—a way of exploring and learning about ideas, ourselves and the world. The goals of art-based inquiry are understanding important topics, imagining possibilities, and inventing new realities. Students create art in order to meet those goals and they do it with a teacher’s guidance. For Creative Connections, art-based inquiry calls for a slight shift in perspective and change in practice. Adopting art-based inquiry does not mean throwing out everything you do. It means seeing art class diff erently and adapting it to a more …

Fgf Ligands And Receptors In Osteochondral Tissues Of The Temporomandibular Joint In Young And Aging Mice, Eliane H. Dutra, Po-Jung Chen, Zana Kalajzic, Sunil Wadhwa, Marja Hurley, Sumit Yadav

College of Dentistry: Faculty Publications

Objective. Fibroblast growth factors (FGFs) are a family of 22 proteins and 4 FGF receptors (FGFRs) that are crucial elements for normal development. The contribution of different FGFs and FGFRs for the homeostasis or disease of the cartilage from the mandibular condyle is unknown. Therefore, our goal was to characterize age-related alterations in the protein expression of FGF ligands and FGFRs in the mandibular condyle of mice. Method. Mandibular condyles of 1-, 6-, 12-, 18-, and 24-month-old C57BL/6J male mice (5 per group) were collected and histologically sectioned. Immunofluorescence for FGFs that have been reported to be relevant …

Insect And Pest Management For Sustaining Crop Production Under Changing Climatic Patterns Of Drylands, Ruchika Kashyap, Sajjan Grover, Heena Puri, Sandeep Kaur, Jagmohan Singh, Karansher S. Sandhu, Gagandeep Kaur, Hinal Kharva, Shivreet Kaur, Balwinder Kaur

Department of Entomology: Faculty Publications

Climate change is alarming, particularly for agriculturists as it severely impacts the development, distribution, and survival of insects and pests, affecting crop production globally. Over time, climate change is drastically tumbling the crop productivity in all the cropping systems, whereas the dryland agriculture with existing low productivity is immensely hit. While all the existing species in drylands, including humans, are coping with extreme climate variations for millennia, future climate change predictions put dryland agriculture in a threat zone. Drylands support 38% of the world’s population; therefore, climate change coupled with population growth and global food security draws the attention of …

Teaching Forensic Entomology With Common Grocery Items: Decomposition And Insect Succession Studies, Erin Bauer, Charles Murrieta, Larry Barksdale

Department of Entomology: Faculty Publications

Forensic science and entomology programs may benefit from using deceased pigs as teaching resources due to anatomical similarities to humans. The use of such animals provides opportunities for students to learn the effects of geographical location and climate on insects; understand insect succession; practice insect collection and identification; and learn post-mortem interval procedures, taphonomic principles of decomposition, and crime scene investigation and management techniques. Forensic entomology and taphonomic studies fit well with educational interests in experiential learning. Pigs may be readily available through animal science departments or local producers, and many institutions may have property where this research can be …

The Persistence And Stabilization Of Auxiliary Genes In The Human Skin Virome, Ema H. Graham, Wesley A. Tom, Alison C. Neujahr, Michael Adamowicz, Jennifer Clarke, Joshua R. Herr, Samodha C. Fernando

Nebraska Center for Virology: Faculty Publications

Background The human skin contains a diverse microbiome that provides protective functions against environmental pathogens. Studies have demonstrated that bacteriophages modulate bacterial community composition and facilitate the transfer of host-specific genes, potentially influencing host cellular functions. However, little is known about the human skin virome and its role in human health. Especially, how viral-host relationships influence skin microbiome structure and function is poorly understood.

Results Population dynamics and genetic diversity of bacteriophage communities in viral metagenomic data collected from three anatomical skin locations from 60 subjects at five different time points revealed that cutaneous bacteriophage populations are mainly composed of …

Intercontinental Comparisons Of Subterranean Host-Parasite Communities Using Bipartite Network Analyses, Altangerel Tsogtsaikhan Dursahinhan, Sebastian Botero-Cañola, Scott L. Gardner

Scott L. Gardner Publications

Rodents living in a subterranean ecotope face a unique combination of evolutionary and ecological pressures and while host species evolution may be driven by the selective pressure from the parasites they harbour, the parasites may be responding to the selective pressures of the host. Here we obtained all available subterranean rodent host-parasite records from the literature and integrated these data by utilizing a bipartite network analysis to determine multiple critical parameters to quantify and measure the structure and interactions of the organisms present in host-parasite communities. A total of 163 species of subterranean rodent hosts, 174 parasite species, and 282 …

“Revisiting The Past”: A Redescription Of Physaloptera Retusa (Nemata, Physalopteridae) From Material Deposited In Museums And New Material From Amazon Lizards = “Revisitando O Passado”: Uma Redescrição De Physaloptera Retusa (Nemata, Physalopteridae) A Partir De Material Depositado Em Museus E Novo Material De Lagartos Amazônicos, Lílian Cristina Macedo, Yuri Willkens, Leandro Maurício Oliveira Da Silva, Scott Lyell Gardner, Francisco Tiago De Vasconcelos Melo, Jeannie Nascimento Dos Santos

Scott L. Gardner Publications

Abstract

Physaloptera Rudolphi, 1819 is a genus of nematodes that includes approximately 100 species parasitic in vertebrates around the world. From these, approximately 30 occur in the Neotropical region, with nine reported from neotropical reptiles. Physaloptera spp. are recognized by their distinct morphology of the apical end and characters of the reproductive system. However, despite the fact that the morphological characters for species diagnosis have been firmly established, we frequently find identification problems regarding poorly detailed descriptions and poorly preserved specimens. These may lead to taxonomic incongruencies. Physaloptera retusa (Rudolphi, 1819) is the most common species of the genus and …

Tapping Into Natural History Collections To Assess Latitudinal Gradients Of Parasite Diversity, Sebastian Botero-Cañola, Scott Lyell Gardner

Scott L. Gardner Publications

Parasites are key components of the biosphere not only due to their huge diversity, but also because they exert important influences on ecological processes. Nevertheless, we lack an understanding of the biogeographical patterns of parasite diversity. Here, we tap into the potential of biodiversity collections for understanding parasite biogeography. We assess species richness of supracommunities of helminth parasites infecting mammal assemblages in the Nearctic, and describe its relation to latitude, climate, host diversity, and land area. We compiled data from parasitology collections and assessed parasite diversity in Nearctic ecoregions for the entire parasite supracommunity of mammals in each ecoregion, as …

Filling The Gap In Distribution Ranges And Conservation Status In Ctenomys (Rodentia: Ctenomyidae), Diego A. Caraballo, Sabrina Laura Lopez, Sebastian Botero-Cañola, Scott Lyell Gardner

Scott L. Gardner Publications

South American subterranean rodents of the genus Ctenomys (Rodentia, Ctenomyidae, tuco-tuco) are one of the most diverse genera among mammals. Recently described species, new taxonomic revisions, and new distribution range delimitation made the revision of distribution areas and conservation status of these mammals mandatory. Implementing the first part of the DAMA protocol (document, assess, monitor, act), here we compile updated sets of species distribution range maps and use these and the number of collection localities to assess the conservation status of ctenomyids. We integrate potential for conservation in protected areas, and levels of habitat transformation to revise previous conservation status …

More People, More Cats, More Parasites: Human Population Density And Temperature Variation Predict Prevalence Of Toxoplasma Gondii Oocyst Shedding In Free-Ranging Domestic And Wild Felids, Sophie Zhu, Elizabeth Vanwormer, Karen Shapiro

School of Veterinary and Biomedical Sciences: Faculty Publications

Toxoplasma gondii is a ubiquitous zoonotic parasite that can infect warm-blooded vertebrates, including humans. Felids, the definitive hosts, drive T. gondii infections by shedding the environmentally resistant stage of the parasite (oocysts) in their feces. Few studies characterize the role of climate and anthropogenic factors in oocyst shedding among free-ranging felids, which are responsible for the majority of environmental contamination. We determined how climate and anthropogenic factors influence oocyst shedding in free-ranging domestic cats and wild felids using generalized linear mixed models. T. gondii oocyst shedding data from 47 studies were systematically reviewed and compiled for domestic cats and six …

Bovine viral diarrhea virus (BVDV) is one of the most important viruses affecting the health and well-being of bovine species throughout the world. Here, we used CRISPR-mediated homology-directed repair and somatic cell nuclear transfer to produce a live calf with a six amino acid substitution in the BVDV binding domain of bovine CD46. The result was a gene-edited calf with dramatically reduced susceptibility to infection as measured by reduced clinical signs and the lack of viral infection in white blood cells. The edited calf has no off-target edits and appears normal and healthy at 20 months of age without obvious …

Host-Genetic-Based Outcome Of Co-Infection By Pcv2b And Prrsv In Pigs, Christian W. Eaton, Hiep Vu, Arabella L. Hodges, Seth P. Harris, Stephen D. Kachman, Daniel C. Ciobanu

School of Veterinary and Biomedical Sciences: Faculty Publications

Replication of porcine circovirus type 2 (PCV2), an important worldwide swine pathogen, has been demonstrated to be influenced by host genotype. Specifically, a missense DNA polymorphism (SYNGR2 p.Arg63Cys) within the SYNGR2 gene was demonstrated to contribute to variation in PCV2b viral load and subsequent immune response following infection. PCV2 is known to induce immunosuppression leading to an increase in susceptibility to subsequent infections with other viral pathogens such as porcine reproductive and respiratory syndrome virus (PRRSV). In order to assess the role of SYNGR2 p.Arg63Cys in co-infections, pigs homozygous for the favorable SYNGR2 p.63Cys (N = 30) …

School of Veterinary and Biomedical Sciences: Faculty Publications

Background: Japanese encephalitis virus (JEV) is a mosquito-borne zoonotic flavivirus and the leading cause of pediatric encephalitis in the Asian Pacific region. The transmission cycle primarily involves Culex spp. mosquitoes and Ardeid birds, with domestic pigs (Sus scrofa domestica) being the source of infectious viruses for the spillover of JEV from the natural endemic transmission cycle into the human population. Although many studies have concluded that domestic pigs play an important role in the transmission cycle of JEV, and infection of humans, the role of feral pigs in the transmission of JEV remains unclear. Since domestic and …

Increased Liver Stiffness Promotes Hepatitis B Progression By Impairing Innate Immunity In Ccl4-Induced Fibrotic Hbv+ Transgenic Mice, Grace Bybee, Youra Moeun, Weimin Wang, Kusum K. Kharbanda, Larisa Y. Poluektova, Srivatsan Kidambi, Natalia A. Osna, Murali Ganesan

Department of Chemical and Biomolecular Engineering: Faculty Publications

Background: Hepatitis B virus (HBV) infection develops as an acute or chronic liver disease, which progresses from steatosis, hepatitis, and fibrosis to end-stage liver diseases such as cirrhosis and hepatocellular carcinoma (HCC). An increased stromal stiffness accompanies fibrosis in chronic liver diseases and is considered a strong predictor for disease progression. The goal of this study was to establish the mechanisms by which enhanced liver stiffness regulates HBV infectivity in the fibrotic liver tissue. Methods: For in vitro studies, HBV-transfected HepG2.2.15 cells were cultured on polydimethylsiloxane gels coated by polyelectrolyte multilayer films of 2 kPa (soft) or 24 kPa (stiff) …

Mesenchymal Stromal Cells And Alpha-1 Antitrypsin Have A Strong Synergy In Modulating Inflammation And Its Resolution, Li Han, Xinran Wu, Ou Wang, Xiao Luan, William Velander, Michael Aynardi, E. Scott Halstead, Anthony S. Bonavia, Rong Jin, Guohong Li, Yulong Li, Yong Wang, Cheng Dong, Yuguo Lei

Department of Chemical and Biomolecular Engineering: Faculty Publications

Rationale: Trauma, surgery, and infection can cause severe inflammation. Both dysregulated inflammation intensity and duration can lead to significant tissue injuries, organ dysfunction, mortality, and morbidity. Anti-inflammatory drugs such as steroids and immunosuppressants can dampen inflammation intensity, but they derail inflammation resolution, compromise normal immunity, and have significant adverse effects. The natural inflammation regulator mesenchymal stromal cells (MSCs) have high therapeutic potential because of their unique capabilities to mitigate inflammation intensity, enhance normal immunity, and accelerate inflammation resolution and tissue healing. Furthermore, clinical studies have shown that MSCs are safe and effective. However, they are not potent enough, alone, to …

Harris, Qiaozhu Su

Department of Biochemistry: Faculty Publications

Background The intestinal epithelial barrier is the interface for interaction between gut microbiota and host metabolic systems. Akkermansia muciniphila (A. muciniphila) is a key player in the colonic microbiota that resides in the mucus layer, whose abundance is selectively decreased in the faecal microbiota of inflammatory bowel disease (IBD) patients. This study aims to investigate the regulatory mechanism among A. muciniphila, a transcription factor cAMPresponsive element-binding protein H (CREBH), and microRNA-143/145 (miR-143/145) in intestinal inflammatory stress, gut barrier integrity and epithelial regeneration.

Methods A novel mouse model with increased colonization of A muciniphila in the intestine of CREBH knockout …

Viral Chemotaxis Of Paramecium Bursaria Altered By Algal Endosymbionts, Huy V.N. Ho, David Dunigan, Miranda E. Salsbery, Irina Agarkova, Zeina Al-Ameeli, James L. Van Etten, John Delong

School of Biological Sciences: Faculty Publications

Chemotaxis is widespread across many taxa and often aids resource acquisition or predator avoidance. Species interactions can modify the degree of movement facilitated by chemotaxis. In this study, we investigated the influence of symbionts on Paramecium bursaria’s chemotactic behavior toward chloroviruses. To achieve this, we performed choice experiments using chlorovirus and control candidate attractors (virus stabilization buffer and pond water). We quantified the movement of Paramecia grown with or without algal and viral symbionts toward each attractor. All Paramecia showed some chemotaxis toward viruses, but cells without algae and viruses showed the most movement toward viruses. Thus, the endosymbiotic …
