Elemental Climate Disaster Texts And Queer Ecological Temporality, Laura Mattson

USF Tampa Graduate Theses and Dissertations

This thesis approaches climate disaster texts as an opportunity to challenge constructions of the body, space, and time. Developed from embodied experiential knowledge about hurricanes, my work will explore how climate disasters can teach us to reimagine human-nature relationships. In my two analysis chapters, I use critical textual analysis and autoethnography to challenge particular representations of the human-nature relationship as a binary between nature and culture. By intervening in the nature-culture binary, I theorize queer ecological temporality as an opportunity to reveal and challenge constructions of nature and time. Working at the intersections of queer and ecocritical theory, this thesis …

Carnivore Population Structure Across An Urbanization Gradient: A Regional Genetic Analysis Of Bobcats In Southern California, Julia G. Smith, Megan K. Jennings, Erin E. Boydston, Kevin R. Crooks, Holly B. Ernest, Seth Riley, Laurel E. K. Serleys, Shaelynn Sleater-Squires, Rebecca L. Lewison

United States National Park Service: Publications

Context In human-dominated landscapes, habitat fragmentation and barriers to movement can interrupt gene flow. While often considered at a local extent, regional analyses are also needed to reveal broader landscape-mediated population processes.

Objectives To explore the relationship between patterns of gene flow and fragmentation resulting from urbanization across southern California, we used the bobcat as an indicator species. We assembled data for a landscape level genetic analysis across southern California from both archived and new samples, including two northern Californian populations for comparison, to identify local and regional areas affected by isolation.

Methods Our regional analyses focused on a dataset …

Asynchronous Carbon Sink Saturation In African And Amazonian Tropical Forests, Wannes Hubau, Simon L. Lewis, Et. Al. Authors

United States National Park Service: Publications

Structurally intact tropical forests sequestered about half of the global terrestrial carbon uptake over the 1990s and early 2000s, removing about 15 percent of 1–3 anthropogenic carbon dioxide emissions. Climate-driven vegetation models 4,5 typically predict that this tropical forest ‘carbon sink’ will continue for decades . Here we assess trends in the carbon sink using 244 structurally intact African tropical forests spanning 11 countries, compare them with 321 published plots from Amazonia and investigate the underlying drivers of the trends. The carbon sink in live aboveground biomass in intact African tropical forests has been stable for the three decades to …

The article presents the materials of herpetological studies conducted in 2007-2018 in the South Aral region. The main work on the study of the species composition, distribution and counting of all reptile species and ecological features was carried out in three large ecosystems (North-Western Kyzyl Kum, Ustyurt and the lower reaches of the Amu Darya). The studies were carried out according to standard methods using point and route counts. In the works, generally accepted methods of zoological and environmental studies are used. As a result of the inventory, the authors identified the modern species composition and number of reptiles in …

Farming Along Desire Lines: Collective Action And Food Systems Adaptation To Climate Change., Thomas F. Thornton, B. Soubry, K. Sherren

Faculty, Staff, and Students

1. We examine collective action in the food system of the Canadian Maritimes to determine its effect on the resilience and adaptive capacity of food producers, distributors, retailers and governance institutions. 2. Our data suggest that beyond their immediate benefits for their participants, expressions of collective action generate higher-level impacts which often translate into drivers of adaptive capacity. 3. Drawing on a metaphor from urban design, we suggest that collective action should be considered a desire line for food systems adaptation: rather than building adaptation strategies based on top-down design, collective action emerges from farmers’ needs and capacities to build …

Development Of Pcr-Based Detection System For Soft Rot Pectobacteriaceae Pathogens Using Molecular Signatures, Md Niamul Kabir, Ali Taheri, C. Korsi Dumenyo

Agricultural and Environmental Sciences Faculty Research

Pectobacterium and Dickeya species, usually referred to as soft rot Enterobacteriaceae, are phytopathogenic genera of bacteria that cause soft rot and blackleg diseases and are responsible for significant yield losses in many crops across the globe. Diagnosis of soft rot disease is difficult through visual disease symptoms. Pathogen detection and identification methods based on cultural and morphological identification are time-consuming and not always reliable. A polymerase chain reaction (PCR)-based detection method with the species-specific primers is fast and reliable for detecting soft rot pathogens. We have developed a specific and sensitive detection system for some species of soft rot Pectobacteriaceae …

Eelgrass Health Survey And Results, Nicholas B. Anderson, Catherine M. Ashcraft, Dante D. Torio, Frederick T. Short

Natural Resources & the Environment

Researchers at the University of New Hampshire designed, tested, and conducted an eelgrass health survey. The primary goal of the survey was to collect health ratings from respondents who had viewed pre-selected images of eelgrass representing a wide range of health conditions. Survey results were used as a calibration and validation to a novel eelgrass health index developed using video-monitoring. Two secondary goals of this this survey were the identification of plant-specific and environmental characteristics important to respondents and the introduction of the new eelgrass health index. This published dataset includes de-identified survey respondent background and demographic data, the survey …

Development And Testing Scenarios For Implementing Land Use And Land Cover Changes During The Holocene In Earth System Model Experiments, Sp Harrison, M-J Gaillard, Bd Stocker, M Vander Linden, Et Al

School of Geography, Earth and Environmental Sciences

Abstract. Anthropogenic changes in land use and land cover (LULC) during the pre-industrial Holocene could have affected regional and global climate. Existing scenarios of LULC changes during the Holocene are based on relatively simple assumptions and highly uncertain estimates of population changes through time. Archaeological and palaeoenvironmental reconstructions have the potential to refine these assumptions and estimates. The Past Global Changes (PAGES) LandCover6k initiative is working towards improved reconstructions of LULC globally. In this paper, we document the types of archaeological data that are being collated and how they will be used to improve LULC reconstructions. Given the large methodological …

Assessment Of Salt Marsh Change On Assateague Island National Seashore Between 1962 And 2016, Anthony Campbell, Yeqiao Wang

Natural Resources Science Faculty Publications

Salt marshes provide extensive ecosystem services, including high biodiversity, denitrification, and wave attenuation. In the mid-Atlantic, sea level rise is predicted to affect salt marsh ecosystems severely. This study mapped the entirety of Assateague Island with Very High Resolution satellite imagery and object-based methods to determine an accurate salt marsh baseline for change analysis. Topobathymetric light detection and ranging was used to map the salt marsh and model expected tidal effects. The satellite imagery, collected in 2016 and classified at two hierarchical thematic schemes, were compared to determine appropriate thematic richness. Change analysis between this 2016 map and both a …

Potential For Managed Aquifer Recharge To Enhance Fish Habitat In A Regulated River, Robert W. Van Kirk, Bryce A. Contor, Christina N. Morrisett, Sarah E. Null, Ashly S. Loibman

Watershed Sciences Faculty Publications

Managed aquifer recharge (MAR) is typically used to enhance the agricultural water supply but may also be promising to maintain summer streamflows and temperatures for cold-water fish. An existing aquifer model, water temperature data, and analysis of water administration were used to assess potential benefits of MAR to cold-water fisheries in Idaho’s Snake River. This highly-regulated river supports irrigated agriculture worth US $10 billion and recreational trout fisheries worth $100 million. The assessment focused on the Henry’s Fork Snake River, which receives groundwater from recharge incidental to irrigation and from MAR operations 8 km from the river, addressing (1) the …

Extensive Marine Anoxia Associated With The Late Devonian Hangenberg Crisis, Feifei Zhang, Tais W. Dahl, Timothy M. Lenton, Genming Luo, Shu Zhong Shen, Thomas J. Algeo, Noah Planavsky, Jiangsi Liu, Ying Cui, Wenkun Qie, Stephen J. Romaniello, Ariel D. Anbar

Department of Earth and Environmental Studies Faculty Scholarship and Creative Works

The global Hangenberg Crisis near the Devonian-Carboniferous boundary (DCB) represents one of the major Phanerozoic mass extinction events, which shaped the roots of modern vertebrate biodiversity. Marine anoxia has been cited as the proximate kill mechanism for this event. However, the detailed timing, duration, and extent of global marine redox chemistry changes across this critical interval remain controversial because most of the studies to date only constrain changes in local or regional redox chemistry. Thus, opinions on the significance of anoxia as a kill mechanism are variable—from anoxia being a primary driver to being relatively unimportant. In this study, we …

Differential Cytotoxicity Induced By Transition Metal Oxide Nanoparticles Is A Function Of Cell Killing And Suppression Of Cell Proliferation, Larry M. Tolliver, Natalie J. Holl, Fang Yao Stephen Hou, Han-Jung Lee, Melissa H. Cambre, Yue-Wern Huang

Biological Sciences Faculty Research & Creative Works

The application of nanoparticles (NPs) in industry is on the rise, along with the potential for human exposure. While the toxicity of microscale equivalents has been studied, nanoscale materials exhibit different properties and bodily uptake, which limits the prediction ability of microscale models. Here, we examine the cytotoxicity of seven transition metal oxide NPs in the fourth period of the periodic table of the chemical elements. We hypothesized that NP-mediated cytotoxicity is a function of cell killing and suppression of cell proliferation. To test our hypothesis, transition metal oxide NPs were tested in a human lung cancer cell model (A549). …

Problematic Plant Monitoring In Homestead National Monument Of America, 2006–2017, Craig C. Young

United States National Park Service: Publications

Abstract

Managers are challenged with the impact of problematic plants, including exotic, invasive, and pest plant species. Information on the abundance, distribution, and location of these plants is essential for developing risk-based approaches to managing these species. Based on surveys conducted in 2006, 2009, 2013, and 2017, Heartland Inventory and Monitoring Network staff and contractors identified a cumulative total of 20 potentially problematic plant species in Homestead National Monument of America (NMA). Of the 13 species found in 2017, we characterized 4 as very low frequency, 4 as low frequency, 2 as medium frequency, and 3 as high frequency. Only …

Tackling Regional Climate Change Impacts And Food Security Issues: A Critical Analysis Across Asean, Pif, And Saarc, Md. Saidul Islam, Edson Kieu

Research Collection Lee Kong Chian School Of Business

Climate change and food security issues are multi-faceted and transcend across national boundaries. Therefore, this paper begins with the premise that regional organizations are optimally positioned to address climate change and food security issues while actively engaging global partners to slow down or reverse current trajectories. However, the potential of regional organizations to play a central role in mitigating these vital concerns has not been realized. In this paper, we focus on three regional organizations—the Association of Southeast Asian Nations (ASEAN), the Pacific Islands Forum (PIF), and the South Asian Association for Regional Cooperation (SAARC) and set out to investigate …

Environmental Injustice: Examining How The New York Times Frames The Flint Water Crisis, Mark Congdon Jr., Quang Ngo, Evan Young

Communication, Media & The Arts Faculty Publications

Perceived as one of the current environmental controversies in the United States, the Flint water crisis represents a case of environmental injustice and has attracted public attention and scrutiny. Among mainstream news media outlets, The New York Times is the newspaper that has intensively published news stories addressing the issue. Using qualitative frame analysis as the method, the researchers examined the way in which The New York Times framed the Flint water crisis from when a federal state of emergency was declared in 2016 to the one-year anniversary of this declaration. Examining how the Flint water crisis is framed in …

Problematic Plant Monitoring In Tallgrass Prairie National Preserve, 2006–2018, Craig C. Young

United States National Park Service: Publications

Abstract

Managers are challenged with the impact of problematic plants, including exotic, invasive, and pest plant species. Information on the abundance, distribution, and location of these plants is essential for developing risk-based approaches to managing these species. Based on surveys conducted in 2006, 2010, 2014, and 2018, Heartland Inventory and Monitoring Network staff and contractors identified a cumulative total of 33 problematic plant species in Tallgrass Prairie National Preserve. Of the 27 species found in 2018, we characterized 14 as very low frequency, 9 as low frequency, 4 as medium frequency, and 0 as high frequency. Only 4 (14.8%) of …

Cats And Conservationists: The Debate Over Who Owns The Outdoors, Dara M. Wald, Anna L. Peterson

Purdue University Press Book Previews

Cats and Conservationists is the first multidisciplinary analysis of the heated debate about free-roaming cats. The debate pits conservationists against cat lovers, who disagree both on the ecological damage caused by the cats and the best way to manage them. An impassioned and spirited conflict, it also sheds light on larger questions about how we interpret science, incorporate diverse perspectives, and balance competing values in order to encourage constructive dialogue on contentious social and environmental issues.

On one side of the cat debate stand many environmentalists, especially birders and conservation organizations, who believe that outdoor cats seriously threaten native wildlife. …
