Language And Power In Social Movements: Hearing All The Voices In Food System Advocacy Narratives, Dianna Winslow

Green Humanities: A Journal of Ecological Thought in Literature, Philosophy & the Arts

[From first paragraph] Everyone must eat. It is this immediate and personal connection to food which drives public and scholarly interest in the complex narratives emerging in what is becoming known as the “food movement”—activism on a global scale that is challenging how the industrialized production, distribution and consumption of food is affecting environmental conditions, food sovereignty and security, human health and wellness, and cultural identities. As the number of food advocacy groups promoting different, yet overlapping, public concerns continues to increase, so does the flow of language used by these groups to shape collective identities and political stances, which …

The Effects Of Estradiol-17Β On The Sex Reversal, Survival, And Growth Of Green Sunfish Lepomis Cyanellus, Chad N. Teal, Daniel J. Schill, Susan B. Fogelson, Colby M. Roberts, Kevin Fitzsimmons, Javan M. Bauder, William T. Stewart, Scott A. Bonar

United States Geological Survey: Staff Publications

The feminization of green sunfish Lepomis cyanellus could expand their utility as a game fish or aquacultured species by preventing overcrowding and precocious reproduction in stocked systems. Feminization of green sunfish could also help elucidate information on their sex determination system. We report the feminization of green sunfish cohorts via oral administration of estradiol-17β (E2) during early development. A low-dose (100 E2 mg per kg of diet) and a high-dose (150 E2 mg per kg of diet) experimental E2 treatment were fed to juvenile green sunfish from 30 to 90 days post-hatch. Fish were subsequently evaluated for any treatment effect …

Relief Wells For Water Resources And Managing Salinity And Waterlogging, Department Of Primary Industries And Regional Development, Western Australia

Natural resources factsheets

Relief wells can provide water resources and help reduce the severity and extent of waterlogging and salinity caused by leaky artesian systems.

A relief well is a 'free flowing' groundwater bore driven by artesian pressure. Such a bore allows groundwater to flow continuously up to the surface by releasing confined pressure stored within the aquifer at depth. This confined artesian pressure is renewed by a percentage of rainfall that infiltrates the soil profile at a higher elevation and recharges aquifers that may be a source of water for a saline seep.

Robust epidemiological models relating wastewater to community disease prevalence are lacking. Assessments of SARS-CoV-2 infection rates have relied primarily on convenience sampling, which does not provide reliable estimates of community disease prevalence due to inherent biases. This study conducted serial stratified randomized samplings to estimate the prevalence of SARS-CoV-2 antibodies in 3717 participants and obtained weekly samples of community wastewater for SARS-CoV-2 concentrations in Jefferson County, KY (USA) from August 2020 to February 2021. Using an expanded Susceptible-Infected-Recovered model, the longitudinal estimates of the disease prevalence were obtained and compared with the wastewater concentrations using regression analysis. The model analysis …

School of Natural Resources: Faculty Publications

Climate change is known to increase the frequency and intensity of hot days (daily maximum temperature ≥30°C), both globally and locally. Exposure to extreme heat is associated with numerous adverse human health outcomes. This study estimated the burden of heat-related illness (HRI) attributable to anthropogenic climate change in North Carolina physiographic divisions (Coastal and Piedmont) during the summer months from 2011 to 2016. Additionally, assuming intermediate and high greenhouse gas emission scenarios, future HRI morbidity burden attributable to climate change was estimated. The association between daily maximum temperature and the rate of HRI was evaluated using the Generalized Additive Model. …

Intensifying permafrost thaw alters carbon cycling by mobilizing large amounts of terrestrial substrate into aquatic ecosystems. Yet, few studies have measured aquatic carbon fluxes and constrained drivers of ecosystem carbon balance across heterogeneous Arctic landscapes. Here, we characterized hydrochemical and landscape controls on fluvial carbon cycling, quantified fluvial carbon fluxes, and estimated fluvial contributions to ecosystem carbon balance across 33 watersheds in four ecoregions in the continuous permafrost zone of the western Canadian Arctic: unglaciated uplands, ice-rich moraine, and organic-rich lowlands and till plains. Major ions, stable isotopes, and carbon speciation and fluxes revealed patterns in carbon cycling across ecoregions …

Vermicompost Versus Traditional Compost Amendments Leads To Different Soil Health Outcomes In A Mediterranean Vineyard, Elizabeth L. Luck

Master of Science in Environmental Sciences and Management Projects

Compost application has become a common practice in vineyard management to increase soil and crop health, however, the environmental externalities such as greenhouse gas emissions (GHG) from cropping systems that utilize organic fertilizers, such as compost, is uncertain. Vermicompost, which is compost created through the digestion of organic matter by earthworms, and its related ‘extract’ are commonly thought to provide more benefits for soil and crop health compared to standard compost. However, organic fertilizers such as vermicompost, vermicompost extract, and compost have not been compared in their effects on soil health in Mediterranean vineyards. In this two-year study, I assessed …

Barriers And Motivations To Residential Pro-Environmental Actions In San Luis Obispo, Dalis Rae De La Mora

Master of Science in Environmental Sciences and Management Projects

Carbon neutrality has become an important focus for many municipalities, with the inclusion of mitigation measures targeted at the residential sector becoming increasingly prominent for the implementation of climate action plans (CAPs). However, many analyses fall short in identifying the barriers and motivations faced by residents to adopting pro-environmental actions in their daily lives, focusing instead on the available actions themselves. This research aims to identify both the barriers and motivations to adopting pro-environmental behaviors and assess their relationship(s) to key demographic variables, along with climate change perceptions. Using the city of San Luis Obispo (SLO) as a case study, …

Developing Positive Thermal Coefficient (Ptc) Heaters For Solar Electric Cooking, Katarina Ivana Brekalo, Andrew Shepherd

Physics

Positive Thermal Coefficients, PTCs, are materials that abruptly change in resistance in response to changes in temperature. The purpose of this experiment is to explore the viability of using the switching type ceramic PTC thermistor as a replacement for current resistive heaters. These types of PTCs have a nonlinear change in resistance with increases in temperature. This device will be used as a temperature-controlling heating element intended to power an Insulated Solar Electric Cooker (ISEC). The ISEC is designed to cook meals throughout the day for impacted communities as an alternative cooking method that doesn’t require biofuel as an energy …

How Neighborhood Characteristics Influence Neighborhood Crimes: A Bayesian Hierarchical Spatial Analysis, Danlin Yu, Chuanglin Fang

Department of Earth and Environmental Studies Faculty Scholarship and Creative Works

Urban crimes are a severe threat to livable and sustainable urban environments. Many studies have investigated the patterns, causes, and strategies for curbing the occurrence of urban crimes. It is found that neighborhood socioeconomic status, physical environment, and ethnic composition all might play a role in the occurrence of urban crimes. Inspired by the recent interest in exploring urban crime patterns with spatial data analysis techniques and the development of Bayesian hierarchical analytical approaches, we attempt to explore the inherently intricate relationships between urban assaultive violent crimes and the neighborhood socioeconomic status, physical environment, and ethnic composition in Paterson, NJ, …

Potential Impacts Of Hemlock Woolly Adelgid Infestation On Forest Overstory And Avian Assemblages In West Michigan, Usa, Nathaniel Sq Wagner

Masters Theses

Invasive species threaten the health and resiliency of native ecosystems wherever they are found. The damage caused by invasive species often leads to a cascade that degrades the ecosystem as a whole. In eastern North America, the invasive insect, hemlock woolly adelgid (Adelges tsugae; HWA), threatens the continued existence of eastern hemlock (Tsuga canadensis) and the species that are associated with it. Often considered a foundation species, eastern hemlock influences the structure and composition of eastern forests by lowering soil temperature, subsequently raising soil moisture content. In the absence of hemlock, many forests become dominated by …

Impacts Of Fertility On Physiological Stress, Photosynthetic Activity, And Crop Development In Salanova Lettuce, Sarah I. Miller

Master of Science in Environmental Sciences and Management Projects

The agricultural industry is one of the main drivers of soil degradation due to conventional crop production methods and overuse of soil which results in accelerated erosion, loss of soil fertility, acidification, and salinization (Lal, 2015). Loss of soil fertility from degradation can be detrimental to crop production as plants grown under nutrient limited conditions show signs of physiological stress and reduced photosynthetic rates leading to reduced yields (Zangani et al., 2021). Organic crop production and fertilizers are viable alternatives to conventional methods as they improve soil fertility and the physiological and biological properties of soil (Ilahi et al., 2021). …
