Unprecedented rates of introduction and spread of non-native species pose burgeoning challenges to biodiversity, natural resource management, regional economies, and human health. Current biosecurity efforts are failing to keep pace with globalization, revealing critical gaps in our understanding and response to invasions. Here, we identify four priority areas to advance invasion science in the face of rapid global environmental change. First, invasion science should strive to develop a more comprehensive framework for predicting how the behavior, abundance, and interspecific interactions of non-native species vary in relation to conditions in receiving environments and how these factors govern the ecological impacts of …

Intellectual Property Rights In The Seed Industry: Barriers To Sustainable Agriculture, Elena A. Filatova Jan 2021

Intellectual Property Rights In The Seed Industry: Barriers To Sustainable Agriculture, Elena A. Filatova

Electronic Theses and Dissertations

The dynamics of the dominant industrial agriculture system restrict the seed industry’s innovative landscape, leading to significant negative consequences including an exacerbation of environmental risks which threaten global food security. This thesis explores how exclusionary intellectual property rights (IPRs) in the context of the seed industry constrict innovation, evolutionary pathways, and opportunities for the implementation of sustainable agriculture methods. To overcome these barriers, the application of an open source framework to seed innovation, specifically through the platform of the Open Source Seed Initiative, is evaluated as a tool for enhancing innovative capacities in seed development while broadening the accessibility and …

The Ecological Resilience Of A Tropical Montane Pine Forest To Droughts, Fire, And Hurricane Disturbance, Daniel Erland Brugger Swann Jan 2021

The Ecological Resilience Of A Tropical Montane Pine Forest To Droughts, Fire, And Hurricane Disturbance, Daniel Erland Brugger Swann

Electronic Theses and Dissertations

Owing to the geographic isolation and unique climatic conditions which occur in tropical montane forests (TMFs), these systems are highly sensitive to changes in both climate and disturbance. Therefore, as ongoing climate change alters disturbance regimes – potentially facilitating multiple disturbance interactions much greater than that of isolated disturbances – TMFs may be shifted to alternate stable states. However, study of TMF resilience is essentially unknown given the lack of long-term studies in these systems. We address the resiliency of the tropical montane pine forests of the Cordillera Central, Dominican Republic using long-term climate records, remeasured vegetation data, and reconstructed …

Heat And Chemical Cues Enhance Germination Rates In Fire-Dependent Chaparral Species, Zachary Litwinowicz Jan 2021

Heat And Chemical Cues Enhance Germination Rates In Fire-Dependent Chaparral Species, Zachary Litwinowicz

Senior Honors Projects

Climate change has caused an increase in the frequency and intensity of fire cycles in chaparral ecosystems. In environments impacted by wildfires, some plant species depend on complex fire cues to germinate. Determining how to best replicate wildfire cues is essential to using fire-recruiter species in restoration efforts. This study examines the effects of various simulated fire cues on four chaparral species: Arctostaphylos manzanita, A. viscida, Ceanothus cuneatus, and C. jepsonii. Seeds were exposed to heat, charate, liquid smoke, or combinations of treatments. Other germination cues, such as cold exposure for all species and acid exposure for Arctostaphylos species, were …

Greenhouse gases (GHG) emissions are widely related to climate change, triggering several environmental problems of global concern and producing environmental, social, and economic negative impacts. Therefore, global research seeks to mitigate greenhouse gas emissions. On the other hand, the use of wastes under a circular economy scheme generates subproducts from the range of high to medium-value, representing away to help sustainable development. Therefore, the use of wastewater as a culture medium to grow microalgae strains that biocapture environmental CO2, is a proposal with high potential to reduce the GHG presence in the environment. In this work, Scenedesmus sp. …

Things Are Getting Worse On Our Way To Catastrophe: Neoliberal Environmentalism, Repressive Desublimation, And The Autonomous Ecoconsumer, Alex Stoner Jan 2021

Things Are Getting Worse On Our Way To Catastrophe: Neoliberal Environmentalism, Repressive Desublimation, And The Autonomous Ecoconsumer, Alex Stoner

Journal Articles

The aim of neoliberal environmentalism was to unleash the market to protect the environment; but as it turns out, things are getting worse on our way to catastrophe. Despite persistent failures, neoliberal environmentalism remains prevalent—and apparently without alternative. This paper directs focus on an often-overlooked dimension of this apparent stasis: the nexus of self and society in advanced capitalism, as shown in the linkage between neoliberal environmentalism and the autonomous ecoconsumer. Marcuse’s concept of repressive desublimation is engaged to better understand how environmentalist desire is currently being thwarted in ways that inhibit movement toward socioecological emancipation. The paper provides an …

Polar Bear Behavior: Morphologic And Physiologic Adaptations, John P. Whiteman Jan 2021

Polar Bear Behavior: Morphologic And Physiologic Adaptations, John P. Whiteman

Biological Sciences Faculty Publications

Polar bears possess morphologic and physiologic characteristics that reflect their terrestrial lineage as members of the bear family (Ursidae) as well as adaptations to the Arctic marine environment. Among marine mammals, they are the least adapted for aquatic life. They exhibit substantial seasonality in body mass, body condition, and many physiological functions, reflecting the annual cycle of both their Arctic sea ice habitat and the availability of their main prey, ringed seals. This hypercarnivorous diet has likely influenced the polar bear’s craniodental morphology and nutritional physiology. Similar to other marine mammal predators, polar bears exhibit a relatively high resting metabolic …

Manipulation Of Lipophilic Antioxidants To Enhance Oxidative Stress Tolerance Andnutritional Quality In Transgenic Sweetpotato, Hosoo Kim, Rengi̇n Özgür Uzi̇lday, Bariş Uzi̇lday, Soeun Kim, Chanju Lee, Sulu Park, Xiaofeng Bian, Yizhi Xie, Sang-Soo Kwak

Turkish Journal of Botany

Overproduction of reactive oxygen species (ROS) in plant cells under environmental stress cause oxidative stress, which is one of major factors limiting the plant productivity. To prevent this limitation by stress conditions, a possible strategy is to strengthen the antioxidant defense of plants by gene manipulation of antioxidant enzymes and low molecular-weight (LMW) antioxidants. LMW antioxidants are important for the plant protection to environmental stress and also have nutritional merits for humans as antiaging and antidisease molecules. Sweetpotato [Ipomoea batatas (L.) Lam] as a nutritional food crop has many advantages in terms of the cultivation on the global marginal lands. …

Farming With Trees: Reforming U.S. Farm Policy To Expand Agroforestry And Mitigate Climate Change, Lingxi Chenyang, Andrew Currie, Hannah Darrin, Nathan Rosenberg Jan 2021

Farming With Trees: Reforming U.S. Farm Policy To Expand Agroforestry And Mitigate Climate Change, Lingxi Chenyang, Andrew Currie, Hannah Darrin, Nathan Rosenberg

Utah Law Faculty Scholarship

Agroforestry systems have enormous potential to mitigate climate change. These systems incorporate trees and shrubs into agricultural production, increasing both soil carbon sequestration and the amount of carbon stored in biomass. Even the most conservative estimates find that agroforestry sequesters two to five times more carbon per acre than the most effective—and better known—climate-friendly practices for annual crops, such as no-till agriculture and cover crops. Agroforestry also offers substantial environmental and economic benefits: clean water, reduced fertilizer and pesticide use, greater resiliency, and higher profitability per acre. Yet there are significant legal and policy barriers to its expansion in the …

Assessing Short-Term Microalgal Community Responses Over Altering Hydrological Conditions In Experimental Wetlands Of Costal Georgia, Maggie M. Kuhn Jan 2021

Assessing Short-Term Microalgal Community Responses Over Altering Hydrological Conditions In Experimental Wetlands Of Costal Georgia, Maggie M. Kuhn

College of Graduate Studies: Theses & Dissertations

Wetlands provide valuable ecosystem services such as nutrient cycling and carbon storage. Microalgae (i.e., diatoms) provide the foundation of primary production and determine rates of energy transfer throughout the system. Climate change models predict an increase in frequency of intense storms and severe drought conditions that pose a threat to known hydrological regimes and wetland ecosystem stability. The purpose of my study was to assess the effects of water permanence (i.e., duration of flooding) on diatom community structure in experimental wetlands. I predicted that wetlands with prolonged periods of flooding (i.e., permanent) would harbor a consistent diatom community throughout flooding …

Macroinvertebrate Responses To Hydrological Variation In Experimental Wetlands., Sergio A. Sabat-Bonilla Jan 2021

Macroinvertebrate Responses To Hydrological Variation In Experimental Wetlands., Sergio A. Sabat-Bonilla

College of Graduate Studies: Theses & Dissertations

Predicted increases in the frequency of intense storms and periods of severe drought due to climate change represent a threat to wetland macroinvertebrate communities through alterations to the hydrological regime. I used experimental ponds to assess the effects of water permanence (i.e., duration of flooding) on the communities of aquatic macroinvertebrates. I predicted that permanent ponds would harbor higher diversity of longer-lived taxa whereas temporary ones will favor colonization by quick turnover, short-lived taxa and support lower consumer diversity. Results show differences in macroinvertebrate communities between permanent and temporary ponds can be mostly explained by hydrology and the amount of …

Attribution Science In Takings Litigation, Daniel J. Metzger Jan 2021

Attribution Science In Takings Litigation, Daniel J. Metzger

Sabin Center for Climate Change Law

Climate science plays a central role in climate litigation, and cases under the Takings Clause of the United States’ and many state constitutions are no exception. In the climate context, takings cases to date have involved claims that challenge the constitutionality of both adaptation and mitigation measures. For instance, real estate developers have claimed that land use and zoning regulations that seek to reduce exposure to climate change impacts constitute regulatory takings. Property owners have claimed that restrictions on the development of fossil fuel infrastructure upset their investment-backed expectations. And property owners adversely impacted by climate-related flood control measures have …

Seed Bank Composition Within Two Sagebrush Communities: A Comparison Of Drought, Microsite, And Aboveground Community Effects, Allison Marie Nunes Jan 2021

Seed Bank Composition Within Two Sagebrush Communities: A Comparison Of Drought, Microsite, And Aboveground Community Effects, Allison Marie Nunes

Cal Poly Humboldt theses and projects

Soil seed banks are critical biodiversity repositories for many dryland plant communities. Understanding how environmental factors alter seed bank composition can provide valuable information on ecological processes within a community and be useful for creating land management strategies. Using the seedling emergence method, I characterized the seed bank of two adjacent dryland plant communities that vary in dominant sagebrush species, structure, and function. Specifically, within an Artemisia arbuscula dominated community and Artemisia cana dominated community, I assessed the influence of three environmental factors on each seed bank: experimentally imposed drought, shrub microsites (compared to interspaces), and aboveground vegetation. Within the …

Impact Of The North American Monsoon On Molt Migrant Passerines, Liuqingqing Yang Jan 2021

Impact Of The North American Monsoon On Molt Migrant Passerines, Liuqingqing Yang

Honors Theses

Breeding, molt, and migration place considerable yearly demands on migrating passerines in North America. Due to conflicts in energy allocation, many species have evolved migration strategies that prevent temporal overlap in these processes. However, there is recent evidence that some passerines which breed in western North America migrate to intermediate stopover sites to carry out molt, conflating molt and migration. Factors influencing the evolution of such a strategy are believed to include both aridity on breeding grounds and dependable flushes of late-summer productivity in the southwestern United States and northwestern Mexico. This productivity occurs due to the brisk rainfall of …

The Role Of Oxygen In Stimulating Methane Production In Wetlands, Jared L. Wilmoth, Jeffra K. Schaefer, Danielle R. Schlesinger, Spencer W. Roth, Patrick G. Hatcher, Julie K. Shoemaker, Xinning Zhang Jan 2021

The Role Of Oxygen In Stimulating Methane Production In Wetlands, Jared L. Wilmoth, Jeffra K. Schaefer, Danielle R. Schlesinger, Spencer W. Roth, Patrick G. Hatcher, Julie K. Shoemaker, Xinning Zhang

Chemistry & Biochemistry Faculty Publications

Methane (CH4), a potent greenhouse gas, is the second most important greenhouse gas contributor to climate change after carbon dioxide (CO2). The biological emissions of CH4 from wetlands are a major uncertainty in CH4 budgets. Microbial methanogenesis by Archaea is an anaerobic process accounting for most biological CH4 production in nature, yet recent observations indicate that large emissions can originate from oxygenated or frequently oxygenated wetland soil layers. To determine how oxygen (O2) can stimulate CH4 emissions, we used incubations of Sphagnum peat to demonstrate that the temporary exposure of …

As nations are transitioning to renewable energy sources, they will need to expand and upgrade their energy infrastructure, including high-voltage power lines (HVPL). We have conducted the first nation-wide survey in the last thirty years to assess public attitudes toward HVPL in the USA. The study evaluates perceptions, knowledge, and attitudes toward building new transmission lines, as these relate to renewable energy, place attachment, and environmental impacts. Our results show that Americans do not recognize how new HVPL could help reduce greenhouse gas emissions; instead, respondents favor moving from centralized energy (large power stations and HVPL) to decentralized energy (local …

Ligand Design In C-Functionalized Cobalt Cyclams For Hybrid Photocatalytic Co2 Reduction, Ethan Edward Jarvis Jan 2021

Ligand Design In C-Functionalized Cobalt Cyclams For Hybrid Photocatalytic Co2 Reduction, Ethan Edward Jarvis

Doctoral Dissertations

Global climate change is one of the most significant risks to both the planet and all life on it. The largest contributor to this ever-growing threat is CO2 and its continued emission into the atmosphere. As a result, many scientists are researching CO2 reduction processes to help slow and potentially reverse the climate change by reducing the atmospheric levels of CO2. Ideally, these reduction processes convert CO2 into useful materials such as hydrocarbon-based fuels such as methanol or ethanol, which could also help remove our dependence on finite natural energy resources. CO2 reduction is challenging to do efficiently however, due …

The Bounds Of Energy Law, Shelley Welton Jan 2021

The Bounds Of Energy Law, Shelley Welton

Faculty Publications

U.S. energy law was born of fossil fuels. Consequently, our energy law has long centered on the material and legal puzzles that bringing fossil fuels to market presents. Eliminating these same carbon-producing energy sources, however, has emerged as perhaps the most pressing material transformation needed in the twenty-first century—and one that energy law scholarship has rightfully embraced. Yet in our admirable quest to aid in this transformation, energy law scholars are largely writing into the field bequeathed to us, proposing changes that tweak, but do not fundamentally challenge, last century’s tools for managing the extraction, transport, and delivery of fossil …

U.S. Climate Litigation In The Age Of Trump: Full Term, Korey Silverman-Roati

Sabin Center for Climate Change Law

From beginning to end, the Trump administration pursued an agenda of climate deregulation. The administration aimed a portfolio of actions at weakening federal climate protections and promoting fossil fuels.1 The executive branch did so by aiming to revise and rescind all major Obama-era agency rules to regulate greenhouse gas emissions, leasing public lands for fossil fuel development, attempting to curtail climate impact consideration in National Environmental Policy Act and Endangered Species Act reviews, and withdrawing energy efficiency measures, among other climate deregulation actions.2 Collectively, this effort served to advance the view that humans are not causing serious climate change and …

Southern Ocean ecosystems are globally important. Processes in the Antarctic atmosphere, cryosphere, and the Southern Ocean directly influence global atmospheric and oceanic systems. Southern Ocean biogeochemistry has also been shown to have global importance. In contrast, ocean ecological processes are often seen as largely separate from the rest of the global system. In this paper, we consider the degree of ecological connectivity at different trophic levels, linking Southern Ocean ecosystems with the global ocean, and their importance not only for the regional ecosystem but also the wider Earth system. We also consider the human system connections, including the role of …

Biological Sciences Faculty Publications

Phenotypic plasticity is one mechanism whereby species may cope with stressful environmental changes associated with climate change. Reef building corals present a good model for studying phenotypic plasticity because they have experienced rapid climate-driven declines in recent decades (within a single generation of many corals), often with differential survival among individuals during heat stress. Underlying differences in thermotolerance may be driven by differences in baseline levels of environmental stress, including pollution stress. To examine this possibility, acute heat stress experiments were conducted on Acropora hyacinthus from 10 sites around Tutuila, American Samoa with differing nutrient pollution impact. A threshold-based heat …

Climate-Induced Human Displacement And Conservation Lands, Jessica Owley

Articles

As climate change leads to both internal displacement and mass migrations, we need not only new places for people to live but also new locations for infrastructure projects and other public needs. Some of the most attractive areas for these new land uses are currently unoccupied land, including land set aside for conservation. Numerous laws restrict the availability and possible uses of public conservation land. Individual agreements and property restrictions encumber private conservation land, varying in the ease with which the restrictions can be modified. For example, privately protected areas in the United States are often encumbered with perpetual conservation …

Geography

The expected reduction of ice algae with declining sea ice may prove to be detrimental to the Pacific Arctic ecosystem. Benthic organisms that rely on sea ice organic carbon (iPOC) sustain benthic predators such as the Pacific walrus (Odobenus rosmarus divergens). The ability to track the trophic transfer of iPOC is critical to understanding its value in the food web, but prior methods have lacked the required source specificity. We analyzed the H-Print index, based on biomarkers of ice algae versus phytoplankton contributions to organic carbon in marine predators, in Pacific walrus livers collected in 2012, 2014 and 2016 from …
