It’S Giving Genocide: What Feminist Theory, Indigenous Thought, And Queer Theory Have To Say About Climate Change, Owen George

MS in Environmental Studies Master's Theses

Climate change is having profound impacts on communities around the world. In some cases, and with time, more and more, the impacts of climate change are happening on a level that constitutes genocide. Raphaël Lemkin’s and Claudia Card’s definitions of genocide are most applicable to climate change as they have broader understandings of victim groups and social death, and they recognize that inaction to prevent reasonably foreseeable harm constitutes genocidal intent. The UN’s more rigid definition does, to a lesser extent, also apply to climate change. Across the three definitions examined here, the argument of climate change as genocide is …

How Does A Global Climate Cycle Affect The Reproductive Output Of A Neotropical Migratory Bird?, Abby K. Bressette, Emma Cummings, Daniel Albrecht-Mallinger, Lesley Bulluck

Undergraduate Research Posters

El-Niño Southern Oscillation (ENSO) causes regional changes in climate and has been found to have varying effects on the survival, fecundity, and recruitment of migratory songbirds. This study seeks to better understand the effect of ENSO on the fecundity of Virginia-breeding Prothonotary warbler (Protonotaria citrea; PROW), a neotropical migratory songbird. PROW breed in the Eastern United States and spend the non-breeding season primarily in Panama and Colombia. Ongoing research in Virginia has found a positive relationship between spring precipitation and predicted number of PROW fledgelings during La Niña, but the opposite during El Niño. To better understand this relationship, we …

When And Where Can Coastal Wetland Restoration Increase Carbon Sequestration As A Natural Climate Solution, Scott F. Jones, Ariane Arias-Ortiz, Dennis Baldocchi, Meagan Eagle, Daniel A. Friess, Catrina Gore, Greg Noe, Stefanie Nolte, Patty Oikawa, Adina Paytan, Jacqueline L. Raw, Brian J. Roberts, Kerrylee Rogers, Charles Schutte, Camille L. Stagg, Karen M. Thorne, Eric J. Ward, Lisamarie Windham-Myers, Erik S. Yando

Biological Sciences Faculty Publications

Coastal wetlands are hotspots of carbon sequestration, and their conservation and restoration can help to mitigate climate change. However, there remains uncertainty on when and where coastal wetland restoration can most effectively act as natural climate solutions (NCS). Here, we synthesize current understanding to illustrate the requirements for coastal wetland restoration to benefit climate, and discuss potential paths forward that address key uncertainties impeding implementation. To be effective as NCS, coastal wetland restoration projects will accrue climate cooling benefits that would not occur without management action (additionality), will be implementable (feasibility) and will persist over management-relevant timeframes (permanence). Several issues …

Response Of Helenium Amarum To Environmental Stressors In The Presence Of Mycorrhizal Fungi And Its Role As A Pollinator Resource, Austin Jameson, Lisa Horth

Biological Sciences Faculty Publications

Globally, climate change is causing shifts in precipitation patterns. Shifting precipitation patterns can be a stressor for many species. One species that is experiencing such stress is Helenium amarum Raf (H. Rock). H. amarum, thrives in dry upland pastures and low-lying grassy and sandy habitat in the mid-Atlantic (USA), where it persists despite storm-driven standing water. Helenium amarum is a species that is toxic to livestock and has been found outside its native range. Temperature and light impacts on germination are already known, but the role of water availability and potential ameliorating effects of mycorrhizae during water stress have …

Abalones At Risk: A Global Red List Assessment Of Haliotis In A Changing Climate, Howard Peters, Gina M. Ralph, Laura Rogers-Bennett

Biological Sciences Faculty Publications

There is increasing awareness that marine invertebrates such as abalones are at risk from the combined stressors of fishing and climate change. Abalones are an important marine fishery resource and of cultural importance to Indigenous and non-Indigenous people. A highly priced marine delicacy, they are inherently vulnerable: individuals are slow-growing and long-lived and successful reproduction requires dense assemblages. However, their global conservation status is poorly understood. Using IUCN Red List methodology, we assessed the extinction risk to all 54 species of abalone (genus Haliotis). Of the 21 fished commercially for human consumption either now and/or in the past, 15 …

Environmental Implications Of Modern Food Production: An Analysis For The Conscious Consumer, Jessica T. Coming

Cal Poly Humboldt theses and projects

This project explores the pathways by which agriculture affects the environment and determines which foods have the greatest climate, water, and land impacts. Agricultural effects on the environment are extensive, from loss of habitat and declines in regional biodiversity to disruption of global nutrient cycles and climate change. Global food production accounts for 26-34% of annual anthropogenic greenhouse gas emissions, makes up 38-46% of habitable land, and is responsible for 70% of freshwater extraction. The effect of agriculture on the environment is most significantly dictated by what type of food is being produced. Animal-based food products consistently have the highest …

"Kindness Eases Change / Love Quiets Fear": Mapping Change And Movement In Octavia Butler's Parable Of The Sower, Elizabeth Hershey

Cal Poly Humboldt theses and projects

In this project I take a digital mapping approach to reading and analyzing Octavia Butler’s Parable of the Sower. A lot has been said about this novel’s relevance to our own world, and the ways it forces us to think about possible futures. To contribute to the conversations surrounding this novel, I add a digital humanities element to the conversation in order to see what digital mapping has to offer in the way of literary analysis and connecting this novel to our own world. Since the novel is so focused on movement and change, I mapped out the movement of …

A Half-Century Of Pacific Salmon Saving Efforts: A Primer On Law, Policy, And Biology, Michael C. Blumm, Daniel J. Rohlf, Adam Eno

Natural Resources Journal

Pacific salmon, the signature species of the Pacific Northwest, have declined across their range for well over a century, due to a myriad of human-caused effects on their habitat and the fish themselves. Restoration efforts—some successful, some halting—began in earnest in the late 20th century, with considerable attention focused on the Columbia Basin, where historically salmon runs were crippled by a large interconnected hydroelectric system of federal and non-federal dams. In the 1980 Northwest Power Act, Congress created an interstate agency, the Northwest Power and Conservation Council, with access to a substantial amount of ratepayer dollars; the agency has chosen …

The Lawlessness Of Sackett V. Epa, William W. Buzbee

Georgetown Law Faculty Publications and Other Works

When the Supreme Court speaks on a disputed statutory interpretation question, its words and edicts undoubtedly are the final judicial word, binding lower courts and the executive branch. Its majority opinions are the law. But the Court’s opinions can nonetheless be assessed for how well they hew to fundamental elements of respect for the rule of law. In particular, law-respecting versus law-neglecting or lawless judicial work by the Court can be assessed in the statutory interpretation, regulatory, and separation of power realms against the following key criteria, which in turn are based on some basic rule of law tenets: analysis …

Tracing Socio-Ecological Resilience In The Milpa, The Monte, And The Kitchen: Milpero And Campesino Perspectives From Tiholop, Yucatan And La Union Libertad, Oaxaca, Mexico, Marisela Chavez

Graduate Student Theses, Dissertations, & Professional Papers

Agrobiodiversity, the diversity of crops that been co-produced through humanenvironment interactions over millennia, constitutes an important part of humanity’s cultural heritage. Agrobiodiversity is as much about the local ecosystem and biotic resources, such as soil, water, pollinators, and microbes, as it is about human processes like sociocultural and linguistic practices, including farming methods, knowledge, skills, and natural resource management. At the center of these dynamics are the smallholder farmers who engage in a range of stewardship practices that contribute to the diversification and evolution of the native crops that in turn support their food security. This research focuses on understanding …

Reducing The Uncertainty In Estimating Soil Microbial-Derived Carbon Storage, Han Hu, Chao Qian, Ke Xue, Rainer Georg Jörgensen, Marco Keiluweit, Chao Liang, Xuefeng Zhu, Ji Chen, Yishen Sun, Haowei Ni, Jixian Ding, Weigen Huang, Jingdong Mao, Rong-Xi Tan, Jizhong Zhou, Thomas W.

Chemistry & Biochemistry Faculty Publications

Soil organic carbon (SOC) is the largest carbon pool in terrestrial ecosystems and plays a crucial role in mitigating climate change and enhancing soil productivity. Microbial-derived carbon (MDC) is the main component of the persistent SOC pool. However, current formulas used to estimate the proportional contribution of MDC are plagued by uncertainties due to limited sample sizes and the neglect of bacterial group composition effects. Here, we compiled the comprehensive global dataset and employed machine learning approaches to refine our quantitative understanding of MDC contributions to total carbon storage. Our efforts resulted in a reduction in the relative standard errors …

Biological Sciences Faculty Publications

Mangroves are one of the most carbon-dense forests on the Earth and have been highlighted as key ecosystems for climate change mitigation and adaptation. Hundreds of studies have investigated how mangroves fix, transform, store, and export carbon. Here, we review and synthesize the previously known and emerging carbon pathways in mangroves, including gains (woody biomass accumulation, deadwood accumulation, soil carbon sequestration, root and litterfall production), transformations (food web transfer through herbivory, decomposition), and losses (respiration as CO₂ and CH₄, litterfall export, particulate and dissolved carbon export). We then review the technologies available to measure carbon fluxes in …

The Climate Crisis And The Class System: An Ethical Analysis, Alia Baig

Williams Honors College, Honors Research Projects

Climate change is a concerning subject that more and more people are beginning to care about. The climate crisis is continuing to affect populations across the globe and shows no signs of slowing. While everyone has been affected by climate change in some capacity, the climate crisis disproportionately affects low-income communities around the world and, specifically, within the United States. I plan to research the ethics of the relationship between climate change and the class system and the goal o f this project is to prove the claim that the class system is the reason for climate change's disproportionate effect …

Climate Change's Effect On Flow Regime, Alexander Ialenti

Williams Honors College, Honors Research Projects

This project will test to see if there is a percent increase in non-perennial streams sampled from 2003-2021. Using data provided by The Cleveland Metroparks, sampling events will be separated by date, flow regime classification, and rain data. Current literature supports the claim that many perennial streams, streams that flow year-round, will become non-perennial streams over time. This shift is predicted to be caused by a change in rain patterns. Both the interval between rain events and the intensity of rainfall per event are predicted to increase. My hypothesis is that there will be an increase in the percentage of …

Wildfires, Climate, And Equity: Towards Sustainable Forest Management And Conservation, Mark Regier Kreider

Graduate Student Theses, Dissertations, & Professional Papers

Forest and conservation sciences are both fields that inherently combine land and people, concerning topics such as the wildfire crisis, impacts of human-caused climate change on ecosystem functioning, and inequity of access to outdoor spaces. The research and science communication in this PhD dissertation explore these issues, integrating the biophysical and social sciences to promote understanding, stewardship, and conservation of human-forest systems. Chapter 1 assesses how humans shape patterns of fire through fire suppression, inadvertently ensuring that fires occur under the most severe conditions and effectively selecting for high-severity fire occurrences. Chapter 2 uses a wilderness area with a fire …

Interannual Growth-Climate Relationships Of Western Larch After Wildfire In The Northwest, Junior Burks

Undergraduate Theses, Professional Papers, and Capstone Artifacts

Montane and mixed-conifer forests in the northwestern United States are burning at rates greater than any time in recent decades, due to the combined impacts of global warming and historical and contemporary land use and land management. Western larch (Larix occidentalis) is a tree of high regional significance, exhibiting a variety of traits that make it resistant and resilient to fire. Because seedlings are more sensitive to environmental stressors than adults, the impacts of climate change are expected to be detectable first in juvenile trees. Recent research shows that the natural regeneration of western larch after wildfires has …

Carbon Allocation To Growth And Storage In Pinus Ponderosa During And Following Experimental Carbohydrate Limitation, Ella M. Keefer

Undergraduate Theses, Professional Papers, and Capstone Artifacts

Understanding how plants allocate carbohydrates to growth and storage in the face of drought and other stresses that reduce carbohydrate availability is crucial to predict ecosystem responses to future stress events. Growth is critical for resource acquisition while storage of carbohydrates is critical as a safeguard during stress. Despite this, how plants allocate carbohydrates to growth and to non-structural carbohydrate (NSC) storage under drought and carbohydrate limitation is poorly understood. We examined how carbohydrate limitation, with and without drought, affects carbon allocation to growth versus stored NSCs. We found that under carbon limitation and depletion of stored NSC, NSC storage …

Using Evidence-Based Scientific Research To Influence Dietary Behavioral Change: Taking A Look In The Mirror, Clifton P. Bueno De Mesquita, Ylenia Vimercati Molano, Lara Vimercati, P. Jacob Bueno De Mesquita

Arts & Sciences Faculty Publications

Science can provide accurate information to society to inform decision-making and behavior. One contemporary topic in which the science is very clear, yet behavioral change has lagged, is climate change mitigation. Climate change scientists use evidence-based research to advocate to the public to adopt emission-reducing behaviors in various sectors such as transportation and food. However, scientists themselves often do not change their own behaviors according to the scientific consensus. We present a case study of a group of natural sciences PhD students, who, when presented with evidence and an opportunity for a behavioral change with implications for climate change mitigation, …

Drought's Lingering Shadow: Monitoring The Recovery Of Sagebrush Steppe Plant Communities After Four Years Of Experimental Drought, Francisco Jesus Chavez

Cal Poly Humboldt theses and projects

Droughts are projected to increase in frequency and intensity due to climate change, which will significantly impact terrestrial ecosystems. However, the response magnitude will vary depending on a system's resistance and resilience to drought. Furthermore, drought may elicit different responses within the hierarchical levels of plant communities (i.e., individual, community, or ecosystem responses). These effects can extend beyond the drought's duration as legacies persist and influence previously disturbed systems. I assessed whether hierarchical responses occurred within two different adjacent sagebrush plant communities, dominated by Artemisia arbuscula and Artemisia cana, during and after an experimental drought. I used nondestructive point frame …

A Closer Look At Denali’S Alpine Wildlife: Assessing The Influences Of Climate And Vegetation Changes On Species In Alaska, Jennifer Lynn Wall

Graduate Student Theses, Dissertations, & Professional Papers

Climate change is amplified in polar regions and could have considerable consequences for biodiversity. Arctic and boreal regions, in particular, have warmed more than double the global average and are experiencing increasing precipitation, thawing permafrost, shrinking snow seasons, and increasing shrub- and tree-line encroachment. These changes are suspected to influence key alpine biodiversity, including species such as collared pikas (Ochotona collaris), hoary marmots (Marmota caligata), and Arctic ground squirrels (Urocitellus parryii). But, we have limited understanding of whether this is true and, if so, which factors drive distributional shifts in response to climate change. For this dissertation, I collected data …

Plasticity In Response To Temperature Magnitude And Variation---From Life History To Thermal Tolerance And Coloration, Austin Rex Hoffman

University of the Pacific Theses and Dissertations

Warming associated with climate change has many direct and downstream effects on animals. For example, warmer developmental temperatures can improve heat tolerance and reduce insect melanization, which is related to coloration, thermoregulation, immunity, desiccation resistance, and potentially life-history traits, such as investment into reproduction and dispersal. Increased temperature variation is also a feature of climate change, and it may have a larger impact on animals than warming. However, I lack insight into the combined effects of temperature magnitude and variability on important traits of life history, thermal tolerance, and coloration. Thus, I integrated temperature variation into thermal performance using a …

Atlantic reef-building corals and coral reefs continue to experience extensive decline due to increased stressors related to climate change, disease, pollution, and numerous anthropogenic threats. To understand the impact of ocean warming and reef loss on the estimated extinction risk of shallow water Atlantic reef-building scleractinians and milleporids, all 85 valid species were reassessed under the IUCN Red List Categories and Criteria, updating the previous Red List assessment of Atlantic corals published in 2008. For the present assessment, individual species declines were estimated based on the modeled coral cover loss (1989–2019) and projected onset of annual severe bleaching events (2020–2050) …

Integrating Biodiversity Protection And Climate Mitigation In Nature-Based Climate Solutions: An Indicator Analysis, Tatyana Feiner

Theses and Dissertations (Comprehensive)

Climate change and biodiversity loss have been recognized as complex, interconnected issues that require synergistic and mutually reinforcing policy solutions. Given the ambitious commitments by the Canadian government to abate the two “wicked problems”, this study investigates whether the government has constructed a policy framework that synthesizes climate and biodiversity concerns through policy integration and mainstreaming processes. Through a semi-systematic and comprehensive content analysis approach, this study assesses the degree to which biodiversity protection and climate mitigation have been effectively mainstreamed into federal policies, programs, and instruments. Specifically, the study constructs an evaluative framework based on established “best practices” of …

Regional Variation In The Role Of Humidity On City-Level Heat-Related Mortality, Multi-Country Multi-City (Mcc) Collaborative Network, Patrick Goodman

Articles

The rising humid heat is regarded as a severe threat to human survivability, but the proper integration of humid heat into heat-health alerts is still being explored. Using state-of-the-art epidemiological and climatological datasets, we examined the association between multiple heat stress indicators (HSIs) and daily human mortality in 739 cities worldwide. Notable differences were observed in the long-term trends and timing of heat events detected by HSIs. Air temperature (Tair) predicts heat-related mortality well in cities with a robust negative Tair-relative humidity correlation (CT-RH). However, in cities with near-zero or weak positive CT-RH, HSIs considering humidity provide enhanced predictive power …
