Modeling Mongoose Rabies In The Caribbean: A Model-Guided Fieldwork Approach To Identify Research Priorities, Caroline C. Sauvé, Erin E. Rees, Amy T. Gilbert, Are R. Berentsen, Agathe Allibert, Patrick A. Leighton

United States Department of Agriculture Wildlife Services: Staff Publications

We applied the model-guided fieldwork framework to the Caribbean mongoose rabies system by parametrizing a spatially-explicit, individual-based model, and by performing an uncertainty analysis designed to identify parameters for which additional empirical data are most needed. Our analysis revealed important variation in output variables characterizing rabies dynamics, namely rabies persistence, exposure level, spatiotemporal distribution, and prevalence. Among epidemiological parameters, rabies transmission rate was the most influential, followed by rabies mortality and location, and size of the initial infection. The most influential landscape parameters included habitat-specific carrying capacities, landscape heterogeneity, and the level of resistance to dispersal associated with topography. Movement …

Applications Of Machine Learning In Microbial Forensics, Ryan B. Ghannam

Dissertations, Master's Theses and Master's Reports

Microbial ecosystems are complex, with hundreds of members interacting with each other and the environment. The intricate and hidden behaviors underlying these interactions make research questions challenging – but can be better understood through machine learning. However, most machine learning that is used in microbiome work is a black box form of investigation, where accurate predictions can be made, but the inner logic behind what is driving prediction is hidden behind nontransparent layers of complexity.

Accordingly, the goal of this dissertation is to provide an interpretable and in-depth machine learning approach to investigate microbial biogeography and to use micro-organisms as …

Evidence On The Effectiveness Of Small Unmanned Aircraft Systems (Suas) As A Survey Tool For North American Terrestrial, Vertebrate Animals: A Systematic Map Protocol, Jared A. Elmore, Michael F. Curran, Kristine O. Evans, Sathishkumar Samiappan, Meilun Zhou, Morgan B. Pfeiffer, Bradley F. Blackwell, Raymond B. Iglay

United States Department of Agriculture Wildlife Services: Staff Publications

Background: Small unmanned aircraft systems (sUAS) are replacing or supplementing manned aircraft and groundbased surveys in many animal monitoring situations due to better coverage at finer spatial and temporal resolutions, access, cost, bias, impacts, safety, efficiency, and logistical benefits. Various sUAS models and sensors are available with varying features and usefulness depending on survey goals. However, justification for selection of sUAS and sensors are not typically offered in published literature and existing reviews do not adequately cover past and current sUAS applications for animal monitoring nor their associated sUAS model and sensor technologies, taxonomic and geographic scope, flight conditions and …

Characterizing The Host Usage And Development Of Ormia Lineifrons (Diptera: Tachinidae), Kyler J. Rogers

Murray State Theses and Dissertations

Insect communication systems are strongly driven by the evolution of signals or signal preferences. These systems rely on a signaler to truthfully emit signals for receivers to interpret. Often, these signals are conspicuously broadcasted. Conspicuous signals involved in animal communication are intended to attract mates, however, these signals are often exploited by eavesdroppers. Thus, many communication systems experience natural selection and sexual selection acting in opposite directions. New adaptations can arise in response to selective pressures, such as eavesdroppers, leading to co-evolving systems between eavesdroppers and hosts, for example. Understanding these systems can provide valuable insight into how unintended receivers …

Aprendizaje Activo Y Pedagogía Culturalmente Relevante En Stem: Tres Lecciones Aprendidas Dentro Y Fuera Del Aula, Teresa Patricia Feria-Arroyo

School of Integrative Biological & Chemical Sciences (Formerly Dept. of Biology)

Uno de los mayores desafíos en la ciencia, la tecnología, la ingeniería y la educación matemática (STEM, por sus siglas en inglés) es mejorar el rendimiento y la retención de estudiantes de diversos orígenes.

Las diferencias inician desde el kínder y continúan hasta los estudios de posgrado. El aprendizaje activo y la pedagogía culturalmente sensible/relevante han mostrado resultados exitosos minimizando estas diferencias educacionales. Desafortunadamente, el aprendizaje activo y la pedagogía culturalmente relevante no son métodos comunes de enseñanza …

The Impact Of Rurality, Underlying Cardiovascular Disease, And Socioeconomic Vulnerability On Covid-19 Outcomes In Georgia, Michael C. Morgan, Lavannya Atri, Jennifer L. Waller, Douglas Miller, Adam E. Berman

Journal of the Georgia Public Health Association

Background: COVID-19 related illnesses have been associated with an increased prevalence of cardiovascular disease sequelae and worsened socioeconomic variables. We sought to investigate the relationship between COVID-19 outcomes, underlying cardiovascular disease, and socioeconomic determinants of health in rural and non-rural counties in the state of Georgia.

Methods: COVID-19, demographic, and socioeconomic data were acquired from publicly available databases including the Center for Disease Control and Prevention’s Social Vulnerability Index (SVI). The relationship between COVID-19 outcomes and markers of cardiovascular disease burden, rurality, and socioeconomic determinants of health was assessed at the county level in Georgia through the beginning of …

The Ecology Of Puha: Identity, Orientation, And Shifting Perceptions Reflected Through Material Culture And Socioreligious Practice, Aaron Robert Atencio

Graduate Student Theses, Dissertations, & Professional Papers

This dissertation explores the assertions that changes in form, function, practice, and perceptions of puha primarily arose from the dispossession of landscapes and oppression of specific religious practices due to Euro-American contact, resource depletion, and reservation confinement. The reservation era placed the indigenous populace into a state of purgatory where treaties and peace relations were consistently repositioned and reneged. The perceptions of the indigenous inhabitants pre and post Euro-American contact detail critical moments that assisted in shaping the dynamic relationship between socioreligious perceptions and the Eastern Shoshone’s identity. What is displayed is a unique set of circumstances that assisted in …

Effects Of Prescribed Fire On Drought Resistance And Recovery In Mixed Conifer Forests Of Lassen Volcanic National Park, California, Zachary J. Wenderott

Cal Poly Humboldt theses and projects

Forests throughout much of the western United States are experiencing increasing climatic variability, often resulting in decreased forest productivity and elevated likelihood of tree mortality. Severe drought, such California’s recent 2012-2015 drought, are projected to increase in intensity, frequency, and severity throughout much of this region in coming years. Forest management has long relied on prescribed fire and mechanical thinning to reduce fuel loads and ameliorate potential fire hazards. These treatments may also have the ability to reduce stand density, alleviate competitive pressures, and allow residual trees access to critical resources during periods of extreme stress. Utilizing a long-term National …

Climate Change And Antibiotic Resistance: A Deadly Combination, Jason P Burnham

2020-Current year OA Pubs

Climate change is driven primarily by humanity's use of fossil fuels and the resultant greenhouse gases from their combustion. The effects of climate change on human health are myriad and becomingly increasingly severe as the pace of climate change accelerates. One relatively underreported intersection between health and climate change is that of infections, particularly antibiotic-resistant infections. In this perspective review, the aspects of climate change that have already, will, and could possibly impact the proliferation and dissemination of antibiotic resistance are discussed.

Habitat Selection By Vulnerable Golden Bandicoots In The Arid Zone, Cheryl A. Lohr, Kristen Nilsson, Colleen Sims, Judy Dunlop, Michael T. Lohr

Research outputs 2014 to 2021

In 2010, vulnerable golden bandicoots (Isoodon auratus) were translocated from Barrow Island, Western Australia, to a mainland predator-free enclosure on the Matuwa Indigenous Protected Area. Golden bandicoots were once widespread throughout a variety of arid and semiarid habitats of central and northern Australia. Like many small-to-medium-sized marsupials, the species has severely declined since colonization and has been reduced to only four remnant natural populations. Between 2010 and 2020, the reintroduced population of golden bandicoots on Matuwa was monitored via capture–mark–recapture data collection, which was used in spatially explicit capture–recapture analysis to monitor their abundance over time. In 2014, we used …

The prevalence of depression among the general population in Central
Sulawesi was the highest in Indonesia (12.3%). Scholars revealed that
disability was one of the main contributing factors of depression and in Central Sulawesi almost half of population was reported having disability (42.1%). This study was intended to identify the association of disability and depression in Central Sulawesi. Cross sectional design study was conducted with utilization of secondary data collection from Riskesdas 2018. Depression, as the main outcome, was assessed by the Mini International Neuropsychiatric Interview (MINI), meanwhile, disability was assessed by the WHODAS instrument. The relationship between these two …

A Historical Ecology Of Aridland Springs In Desert National Wildlife Refuge, Nuwu/Nuwuvi (Southern Paiute/Chemehuevi) Ancestral Territory, Nevada, Yarrow Sarah Valentine Geggus

Dissertations and Theses

Aridland springs are among the most threatened ecosystems in the world. Vital to desert ecologies and Indigenous cultures, these complex and individualistic ecosystems have layered histories. To inform management in the changing landscape of Desert National Wildlife Refuge, a 1.6 million acre protected area in Southern Nevada, I conducted a historical ecology study of a sample of ten upland springs. Through a six-part interdisciplinary methodology including interviews, archaeological survey, botanical survey, and archival research, I summarize findings into three broad eras: the Nuwu/Nuwuvi pre-Contact Era, the Settler Era, and the U.S. Fish and Wildlife Service Era.

For millennia, Nuwu/Nuwuvi drank …

Principled Eclecticism: A Mix And Match Solution For Rural Thai Classrooms?, Andrew Biggs, Oranuch Limtasiri, Umporn Watchana

Asia-Pacific Social Science Review

The methodology of principled eclecticism employs a number of different teaching theories towards a specific set of goals. This quasi-experimental qualitative research examined whether principled eclecticism would affect learning achievements and attitude towards English by students in remote areas of Thailand, with a view to re-examining Thailand’s educational policy. A total of 20 hours of teaching was conducted on primary school students at a school in the remote rural northeastern province of Kalasin using principled eclecticism. Pre- and post-tests revealed improved learning achievements to a significant degree; however, when broken down into sections, significant learning achievements tended to be in …

Medical Marijuana And Opioids (Memo) Study: Protocol Of A Longitudinal Cohort Study To Examine If Medical Cannabis Reduces Opioid Use Among Adults With Chronic Pain, Chinazo O. Cunningham, Joanna L. Starrels, Chenshu Zhang, Marcus A. Bachhuber, Nancy L. Sohler, Frances R. Levin, Haruka Minami, Deepika E. Slawek, Julia H. Arnsten

School of Medicine Faculty Publications

Introduction In the USA, opioid analgesic use and overdoses have increased dramatically. One rapidly expanding strategy to manage chronic pain in the context of this epidemic is medical cannabis. Cannabis has analgesic effects, but it also has potential adverse effects. Further, its impact on opioid analgesic use is not well studied. Managing pain in people living with HIV is particularly challenging, given the high prevalence of opioid analgesic and cannabis use. This study's overarching goal is to understand how medical cannabis use affects opioid analgesic use, with attention to Δ9-tetrahydrocannabinol and cannabidiol content, HIV outcomes and adverse events. Methods and …

The Circular City And The Building Sector, Chiara Franz

Fondazione Eni Enrico Mattei Working Papers

The essay deals with the issue of urban circularity understood as a subset of the Circular Economy paradigm, highlighting potential and limits of an emerging new model spreading on a global scale. The critical reasoning starts from a very recent production of institutional documents and the still reduced scientific production around and over this topic to propose an unorthodox interpretation on the relationship between circularity and city. The building industry is considered as a key sector to promote and improve circularity in cities and some experimental case studies are presented as a proof of the relevant potentials. The essay attempts …

Are Giant Pandas (Ailuropoda Melanoleuca) Averse To Inequity?, Miranda R. Trapani

Theses and Dissertations

Inequity aversion, a negative response to situations of unequal reward distribution, is a cognitive trait usually seen in social species. This capacity is thought to regulate cooperative relationships in intelligent, cognitively flexible animals. Giant pandas are a unique case in that wild populations are characterized as nonsocial, however captive populations are socially housed until sexual maturity. This allows for the study of a nonsocial species in a social context and thus the assessment of socio-cognitive flexibility across evolutionarily distant taxa. Here, we assessed whether the giant panda (Ailuropoda melanoleuca) displays inequity aversion by testing ten juveniles living at …

Black Vulture Conflict And Management In The United States: Damage Trends, Management Overview, And Research Needs, Bryan M. Kluever, Morgan B. Pfeiffer, Scott C. Barras, Brett G. Dunlap, Lee A. Humberg

Human–Wildlife Interactions

Contrary to rapid declines of many vulture (Accipitridae, Cathartidea) species worldwide, black vulture (Coragyps atratus) populations are increasing and expanding their range in North America. Vultures exhibit complex behaviors and can adapt to any human-dominated landscape or land use. These traits, combined with population growth and range expansion, have contributed to increased human–vulture conflicts. Our goal was to summarize the current status and trends in human–black vulture conflicts (hereafter human–vulture conflicts), review available management strategies, identify knowledge gaps, and provide recommendations to enhance management and understanding of this species and the associated conflicts. We found human–vulture conflicts are …

We must ensure that trials are scientifically, politically, and socially robust, publicly accountable, and widely transparent.

Gene drive organisms (GDOs), whose genomes have been genetically engineered to spread a desired allele through a population, have the potential to transform the way societies address a wide range of daunting public health and environmental challenges. The development, testing, and release of GDOs, however, are complex and often controversial. A key challenge is to clarify the appropriate roles of developers and others actively engaged in work with GDOs in decision-making processes, and, in particular, how to establish partnerships with relevant authorities and other …

Scavenging Of Animal Carcasses By Gumaga Nigricula (Sericostomatidae, Trichoptera), An Apparent Herbivore, Stephanie M. Carlson, Pablo Rodriguez-Lozano, Hana Moidu, Robert A. Leidy

Western North American Naturalist

Caddisflies within the genus Gumaga are generally considered shredders (i.e., consumers of leaf litter) or grazers (i.e., consumers of algae). We report on observations of Gumaga nigricula scavenging animal carcasses within and adjacent to isolated pools along intermittent reaches of Coyote Creek, Santa Clara County, California, USA. In particular, during the summer of 2018, we observed G. nigricula scavenging fish carcasses within isolated pools as well as bits of flesh from the bones of a black-tailed deer (Odocoileus hemionus columbianus) deposited on the stream bank. To the best of our knowledge, our observations represent the first published record …

Community Health Sciences

Background: Maternal mortality is a public health problem that disproportionately affects low and lower-middle income countries (LMICs). Appropriate data sources are lacking to effectively track maternal mortality and monitor changes in this health indicator over time.
Methods: We analyzed data from women enrolled in the NICHD Global Network for Women's and Children's Health Research Maternal Newborn Health Registry (MNHR) from 2010 through 2018. Women delivering within research sites in the Democratic Republic of Congo, Guatemala, India (Nagpur and Belagavi), Kenya, Pakistan, and Zambia are included. We evaluated maternal and delivery characteristics using log-binomial models and multivariable models to obtain relative …

Sea Otter Diet Composition With Respect To Recolonization, Life History, And Season In Southern Southeast Alaska, Nicole Laroche

Fisheries

Until translocation efforts in the 1960s, sea otters (Enhydra lutris) were absent from Southeast Alaska due to extirpation by the fur trade in the 18th and 19th centuries. About 400 sea otters were reintroduced to six Southeast Alaska locations, including two sites near Prince of Wales Island in southern Southeast Alaska. The most recent US Fish and Wildlife Service population count, completed in 2012, estimated that about 25,000 sea otters inhabited Southeast Alaska. Sea otters will reduce invertebrate prey biomass when recolonizing an area. By quantifying sea otter diets and caloric intake according to recolonization patterns, we can better understand …

Tracing Carbon Sources Of Southern Beaufort Sea And Chukchi Sea Polar Bears Using Stable Isotope Analyses, Malia E.K. Smith

Marine Biology

The Southern Beaufort Sea (SBS) polar bear (Ursus maritimus) subpopulation has declined in response to sea ice loss, while the Chukchi Sea (CS) subpopulation appears stable. The substantial population decline in the SBS subpopulation in recent years is concurrent with increases in the proportion of polar bears coming on shore, and the duration they spend there. Both of these changes have been associated with the loss of access to their primary sea ice habitat, which is mainly used as a platform to hunt seals. The first objective of this study was to determine if the SBS and CS polar bear …

Wildfire Risk Assessment For A Municipal Watershed In Western Oregon, Usa: Methods For Projecting The Impact Of Mid-21st Century Climate Change On Wildfire Hazard, Andy Mcevoy

Dissertations and Theses

In the western United States, climate change is projected to lead to significant changes in regional wildfire regimes. Historically, forests west of the Cascade crest in Oregon and Washington, USA (westside) have been characterized by low-frequency wildfire events, but climate change projections indicate that wildfire could become a more common disturbance, altering ecological processes and impairing ecosystem services like surface water quality and quantity. Wildfire risk assessments based on simulation models have been used in high frequency fire regimes to evaluate contemporary and future risk, but present unique challenges in westside forests because characteristic low annual burn probabilities result in …

The Effect Of Cyanobacteria On Transgenerational Responses In Daphnia Pulicaria, Olivia Williams

2020 Fall Honors Capstone Projects - Archive

'Transgenerational plasticity' occurs when environmental cues alter the expression of traits in offspring and future generations. This experiment examined the influence of low-quality cyanobacteria (Anabaena) on across-generation responses in a common water flea (Daphnia pulicaria) to quantify whether changes in food quality from dietary cyanobacteria can induce transgenerational effects. Three Daphnia clones from Lake Mendota (WI) were maintained at 14C, 16:10 photoperiod until the third laboratory generation; animals from each clonal line were then reared for multiple generations on diets that contained varying amounts of cyanobacteria (either 100% Scenedesmus or 70% Scenedesmus, 30% Anabaena). General linear models and a posthoc …
