The Role Of Genome Duplication In Big Sagebrush Growth And Fecundity, Bryce A. Richardson, Matthew J. Germino, Marcus V. Warwell, Sven Buerki

Biology Faculty Publications and Presentations

Premise: Adaptive traits can be dramatically altered by genome duplication. The study of interactions among traits, ploidy, and the environment are necessary to develop an understanding of how polyploidy affects niche differentiation and to develop restoration strategies for resilient native ecosystems.

Methods: Growth and fecundity were measured in common gardens for 39 populations of big sagebrush (Artemisia tridentata) containing two subspecies and two ploidy levels. General linear mixed-effect models assessed how much of the trait variation could be attributed to genetics (i.e., ploidy and climatic adaptation), environment, and gene–environment interactions.

Results: Growth and fecundity variation were explained well …

Analyzing Genetic Variation Of The Tussock Cottongrass Among Ecotypes Along A Latitudinal Gradient Through Transcriptomics, Carmen Webster

Open Access Theses & Dissertations

The Arctic is seeing some of the most extreme effects of climate change that induce environmental pressures, including warmer temperatures and longer growing seasons. Due to this, taxa may need to adapt or migrate in order to survive. The long-lived tussock cottongrass, Eriophorum vaginatum, is a foundation species in the Arctic, and little is currently known about the genetic constraints that could be playing a role in how this species will respond to the changing climate. Specific gene families that play an important role in signaling genetic pathways related to plant phenology and response to environmental stress are likely to …

Climate-Driven Impacts Of Warming And Grazing On Sub-Arctic Coastal Wetlands In Alaska, Ryan T. Choi

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Climate change is rapidly warming the Arctic, especially at lower latitudes. Warmer temperatures and earlier springs are altering the timing of plants and animals, especially for long-distance migratory herbivores. Changes in the timing of both plants and herbivores have the potential to impact plant productivity and nutrient cycling, while also altering plant community diversity and composition.

In chapter 2, I conducted a field experiment to investigate how earlier growing seasons and differences in arrival times of migratory geese influence physical traits of sedge forage species. I found that both an earlier growing season and late grazing by geese had similar …

The BCG vaccine is known to impart nonspecific immunological benefits alongside conferring protection to tuberculosis in endemic regions. It is also known to protect against bladder cancer and other respiratory tract infections. During the coronavirus disease 2019 (COVID-19) pandemic, the BCG vaccine has gained attention due to its role in conferring protective immunity. We demonstrate the potential immunological protective mechanisms that play a role against COVID-19. We conduct a global assessment of the countries that have the highest and lowest mortality rates determined by an a priori methodology. Lastly, we discuss the potential limitations of incorporating BCG vaccines as potential …

Weedy Relations: Narratives Of Invasion And Intimacy With Tamarisk In The Chihuahuan Desert, Shannon S. Pepper

Geography ETDs

Tamarix spp., also known as salt cedar or tamarisk, is a shrub that has garnered a notorious reputation in North America as an invasive plant, with widespread policy and research advocating for its eradication in the Southwest U.S. and Northern Mexico. This study examines both governmental conservation documents and news articles to investigate narrative trends on tamarisk in the Southwestern U.S. and Northern Mexico as a contiguous region (the Chihuahuan Desert), expanding on current research to include transborder effects on the perception and management of introduced species. This paper asks: In the last 25 years, how has the movement, …

Exploring Linkages Between Landscape Patterns And Freshwater And Estuarine Bivalves In The Coast Range Of Oregon, Kaegan Michael Scully-Engelmeyer

Dissertations and Theses

Spatial configurations of landscape variables (biotic, abiotic, and socio-ecological) affect and are affected by ecological processes and species in watersheds. This dissertation explores relationships among landscape patterns, ecosystem processes and bivalve species dynamics in coastal watersheds in Oregon, USA. I approached this broad topic through two primary avenues of research: investigating cross-ecosystem threats from pesticide use in forestland management to downstream aquatic environments, and the landscape ecology of an at-risk freshwater mussel species.

Terrestrial land use activities present cross-ecosystem threats to riverine and marine species and processes. Specifically, pesticide runoff can disrupt hormonal, reproductive, and developmental processes in aquatic organisms, …

The Nexus Of Climate Change, Covid-19, And Environmental Justice On Children's Health, Emma Pennea, Laura Anderko, Caroline Moore, Ruth Mcdermott-Levy

Journal of Applied Research on Children: Informing Policy for Children at Risk

Climate change poses a threat to children, who are increasingly vulnerable, depending on adults to protect them from the impacts of these changes including extreme weather events, poor air and water quality and risk to mental health. Children living in poverty carry additional burdens and risks, living in environments that consistently experience poor air and water quality from polluting industries, compounded by the effects of climate change. COVID-19 has placed additional challenges to children’s health and increases the complexity of addressing climate change and environmental justice. The intersection between climate change and COVID-19 exacerbates these existing disparities by impacting children's …

Quantifying Resource Use Among Insectivorous Bat Species With Overlapping Distributions, Shannon Whitney

Master of Science in Integrative Biology Theses

Bats make up 20% of all mammalian species, are globally distributed, and are the only mammals capable of sustained flight. Bats have adapted to feed on insects, scorpions, aquatic arthropods, mammals, birds, reptiles, amphibians, fish, blood, carrion, fruit, flowers, nectar, pollen, and even seeds and foliage. However, the feeding ecology of these organisms is not well understood. Most bat species in North America rely on the same method of foraging and locomotion. The geographical range and habitats of these bats also commonly overlap. Bat feeding ecology studies have used fecal analysis to identify consumed prey species. Factors such as time …

Effects Of Acid Deposition And Changing Climate On The Hydrochemistry And Critical Loads Of Watersheds In The Adirondack Region Of New York, Shuai Shao

Dissertations - ALL

Despite decreases in acidic deposition since the 1970s, the recovery of surface waters from acidification has been limited primarily due to the depletion of exchangeable base cations, net mineralization of organic sulfur and nitrogen and release of previously retained SO42- and NO3-, and increases in concentrations of naturally occurring organic acids from soil. The future recovery of stream chemistry from acidic deposition may be altered by projected increases in temperature and precipitation associated with a changing climate. The goals of this study were to conduct a modeling analysis of the response of soils and streams in the Adirondack Park, New …

Months-Long Spike In Aqueous Arsenic Following Domestic Well Installation And Disinfection: Short- And Long-Term Drinking Water Quality Implications, M. L. Erickson, E. D. Swanner, Brady A. Ziegler, J. R. Havig

Earth and Environmental Geosciences Faculty Research

Exposure to high concentration geogenic arsenic via groundwater is a worldwide health concern. Well installation introduces oxic drilling fluids and hypochlorite (a strong oxidant) for disinfection, thus inducing geochemical disequilibrium. Well installation causes changes in geochemistry lasting 12 + months, as illustrated in a recent study of 250 new domestic wells in Minnesota, north-central United States. One study well had extremely high initial arsenic (1550 µg/L) that substantially decreased after 15 months (5.2 µg/L). The drilling and development of the study well were typical and ordinary; nothing observable indicated the very high initial arsenic concentration. We hypothesized that oxidation of …

Determining Dietary Niche In Primates Using Portable X-Ray Fluorescence, Theresa C. Schwartz

Ursidae: The Undergraduate Research Journal at the University of Northern Colorado

Diet is a critical component of the ecology of an animal. Many dietary reconstructions involve destruction of the sample. Portable X-Ray fluorescence (pXRF), however, is a non-destructive method of gathering elemental data. This is important for research in biological anthropology and diet reconstructions because it leaves a sample intact of which there might only be few specimens. There has been a gap in dietary reconstructions using non-destructive methods like pXRF which is portable, cheaper, and as accurate as destructive methods and should therefore be implemented into research of this nature. This research attempts to validate this method by determining dietary …

Call Repertoire And Inferred Ecotype Presence Of Killer Whales (Orcinus Orca) Recorded In The Southeastern Chukchi Sea, Brijonnay C. Madrigal, Jessica L. Crance, Catherine L. Berchok, Alison K. Stimpert

United States Department of Commerce: Staff Publications

Killer whales occur in the Arctic but few data exist regarding the ecotypes present. The calling behavior differs among ecotypes, which can be distinguished based on pulsed call type, call rate, and bandwidth. In this study, a passive acoustic recorder was deployed 75 km off Point Hope, Alaska, in the southeastern Chukchi Sea to identify which ecotypes were present. A total of 1323 killer whale pulsed calls were detected on 38 of 276 days during the summers (June–August) of 2013–2015. The majority of calls (n = 804, 61%) were recorded in 2013 with the most calls recorded in July …

A Systematic Review Of The Rationale For Vaccine Hesitancy Among American Parents, Jordan Luttrell-Freeman, Timothy J. Bungum, Jennifer R. Pharr

Environmental & Global Health Faculty Research

Vaccines are one of the most successful interventions in the history of public health. They are largely responsible for the near eradication of several diseases. However, some people are vaccination averse which can lead to vaccine hesitancy. Vaccine hesitant parents are those that refuse or delay getting their children vaccinated despite the availability of vaccination services. This phenomenon often occurs despite parent’s belief that vaccines are effective. The purpose of this review was to exam available literature to identify predictors of vaccine hesitancy among parents and parental rationale for vaccine hesitancy

Environmental & Global Health Faculty Research

Providing an enabling nurturing care environment for early childhood development (ECD) that cuts across the five domains of the Nurturing Care Framework (i.e., good health, adequate nutrition, opportunities for early learning, security and safety and responsive caregiving) has become a global priority. Brazil is home to approximately 18.5 million children under 5 years of age, of which 13% are at risk of poor development due to socio-economic inequalities. We explored whether the Early Childhood Friendly Municipal Index (IMAPI) can detect inequities in nurturing care ECD environments across the 5570 Brazilian municipalities. We examined the validity of the IMAPI scores and …

Mapping Heat Vulnerability Index Based On Different Urbanization Levels In Nebraska, Usa, Babak J. Fard, Rezaul Mahmood, Michael Hayes, Clinton M. Rowe, Azar M Abadi, Martha Shulski, Sharon Medcalf, Rachel Lookadoo, Jesse E. Bell

School of Natural Resources: Faculty Publications

Despite similar incidence rates, Heat Vulnerability Index (HVI) in rural areas is under- studied in comparison to urban areas. • The environmental vulnerability variables in rural areas are dissimilar to urban areas, so we applied different variables to calculate them. • We found different organization of socioeconomic variables in calculated HVIs, suggesting separate heat strategies for urbanization levels.

Heatwaves cause excess mortality and physiological impacts on humans throughout the world, and climate change will intensify and increase the frequency of heat events. Many adaptation and mitigation studies use spatial distribution of highly vulnerable local populations to inform heat reduction and …

In Pursuit Of Comparability: Evaluating Influence And Interaction Among Components Of The Home Range Estimation Process In Chimpanzee Datasets, Jillian J. Rutherford

Geography ETDs

The home range (HR) is a fundamental manifestation of an animal’s spatial behavior, but its study has been limited by unclear, unreliable, and unstandardized methodological approaches for measurement. The lack of a comprehensive evaluation of the influence of components of the HR estimation process has hampered consensus over best practices for collecting and analysing movement data. This leads to wide variation in practice, thwarting direct comparability between HR estimates and curtailing the cohesive power of cross-study findings necessary for testing hypotheses and developing appropriate conservation and management strategies. In this thesis I explore the influence of and interaction between common …

Growth Hormone And Aging: New Findings., Andrzej Bartke, Erin Hascup, Kevin Hascup, Michal M Masternak

Articles

Complex relationships between growth hormone (GH) signaling and mammalian aging continue to attract attention of many investigators. Recent results include evidence that the impact of GH on genome maintenance (DNA damage and repair) is drastically different in normal as compared to cancer cells, consistent with GH promoting aging and cancer progression. Impact of GH on DNA methylation was studied as a possible mechanism linking actions of GH during early life to the trajectory of aging. Animals with reduced or enhanced GH signaling and novel animals with adipocyte-specific deletion of GH receptors were used to elucidate the effects of GH on …

Host-Parasite Interactions Within Food Webs, Adam Zvanut Hasik

Graduate Theses and Dissertations

Parasitism is one of the most common life history strategies employed in nature, yet the effects of parasites are often thought to be minimal, and the vast majority of studies fail to consider parasites and their effects on host organisms. This is likely a problem, as the magnitude of parasite-mediated effects on their hosts can be quite large. Additionally, the effects of parasites are known to extend beyond the host to affect other species interactions. I used a series of approaches to gain a more integral understanding of host-parasite interactions by studying (1) the effects of parasites on biotic interactions …

Engaging Middle Schoolers: Teaching Strategies For Boosting Independent Reading Motivation In Middle School, Hannah Schrempp

School of Education and Leadership Student Capstone Projects

This capstone investigates and describes the factors that impact adolescent reading motivation. With access to modern technology, limited resources at home, and a shift in teaching practices, adolescent readers do not find value in reading. Many guardians struggle with supporting their middle school readers at home due to social and economic factors. A combination of articles, studies, and assessments, help answer the question, What factors impact reading motivation in middle school students to help them identify as readers? Research concludes that creating a print-rich environment, giving access to high-interest books, building a positive relationship with family members, and giving students …

Paleobiology Of A Large Mammal Community From The Late Pleistocene Of Sonora, Mexico, Rachel A. Short, Laura G. Emmert, Nicholas A. Famoso, Jeff M. Martin, Jim I. Mead, Sandy L. Swift, Arturo Baez

ETSU Faculty Works

A paleontological deposit near San Clemente de Térapa represents one of the very few Rancholabrean North American Land Mammal Age sites within Sonora, Mexico. During that time, grasslands were common, and the climate included cooler and drier summers and wetter winters than currently experienced in northern Mexico. Here, we demonstrate restructuring in the mammalian community associated with environmental change over the past 40,000 years at Térapa. The fossil community has a similar number of carnivores and herbivores whereas the modern community consists mostly of carnivores. There was also a 97% decrease in mean body size (from 289 kg to 9 …

Correlation Of Sun Exposure Score And Vitamin D Intake Withserum 25(Oh)D Levels In Older Women, Kholidatul Husna, Novira Widajanti, Sri Sumarmi, Hadiq Firdaus

Jurnal Penyakit Dalam Indonesia

Introduction. Indonesia is a tropical country, but the prevalence of vitamin D deficiency in older women is high due to the lack of sun exposure and low vitamin D intake. Some previous studies have reported that people from rural areas have higher serum 25(OH)D levels compared to those from urban areas. This study was conducted to analyze the correlation between sun exposure score and vitamin D intake with serum 25(OH)D levels of older women from rural areas. Methods. This was an analytic cross-sectional study involving older women in two villages from Wonorejo and Kraton Districts, Pasuruan Regency, in June 2020 …

This research aimed to address the impact of non-health trainees as a part of the emergency health response during the Ebola outbreak within Sierra Leone. The non-health trainees, including sanitation workers within health settings, ambulance drivers, burial teams, prison officers, community engagement staff, border officers, traditional birth assistants, etc. was contrasted with individuals receiving clinical and patient-care training. The data were taken from weekly situation reports published by the Internal Organization for Migration in 2015. Using a negative binomial model, we sought to determine the incidence rate ratio of weekly cases and deaths as a result of new trainees. Trainees …

A Review Of Marine Turtle Orientation And Artificial Lighting Impacts With Novel Results From Florida’S Gulf Coast, Andrea M. Fisher

USF Tampa Graduate Theses and Dissertations

Artificial light (i.e. unnatural light emitting from a human-made source) is one of the most extensively distributed, and least managed, type of anthropogenic pollution. Due to the disproportionally high rates of urbanization in critical coastal ecosystems, species, like marine turtles that use beach habitat for nesting activities, are especially vulnerable. Marine turtles employ the use of multiple visual cues (e.g. wavelength, intensity, background illumination, and dark silhouettes) to conduct sea-finding behavior and different variations in cue usage exist across species and geographic location. During nesting and emergence activities, orientation can be interrupted and manipulated by artificial lighting resulting in lower …

Cetacean Maternal Investment: Importance In Conservation Across Species And Drivers For Interspecific Altruism, Christopher Klein

USF Tampa Graduate Theses and Dissertations

Cetacean maternal investments can be useful for conservation management as well as examining behaviors such as interspecific altruism in the humpback whale, Megaptera novaeangliae. Cetaceans are among the most threatened group of marine mammals. In the second chapter, maternal investments across ~90 species/subspecies of Cetacea were analyzed to aid in the understanding of recovery/replacement for conservation and management. Using Principal Components Analysis (PCA), a relative maternal-investment index for 41 cetacean species was built. The maternal-investment index was a composite of four maternal-investment variables, the duration of gestation, lactation, calving intervals, and the number of reproduction years per female per species. …
