Judicial Review Of Scientific Uncertainty In Climate Change Lawsuits: Deferential And Nondeferential Evaluation Of Agency Factual And Policy Determinations, Robert L. Glicksman, Daniel Kim, Keziah Groth-Tuft

GW Law Faculty Publications & Other Works

Scientific determinations are often at the heart of environmental disputes. When those disputes take the form of litigation, the courts may be called on to determine whether an administrative agency’s treatment of the science warrants deference. For several reasons, judges are inclined to apply deferential review to agency factual and policy science-based determinations. Most judges are not trained in the language and methods of science. They may be reluctant to intervene on matters on which their lack of expertise risks producing uninformed judgments. If a statute delegates to an agency the responsibility of making those determinations, courts may be loath …

The Effects Of Average Annual Temperature On Flowering Times And Flower Count, Angela Copploe

Williams Honors College, Honors Research Projects

Over a course of 15 years, three different species of flowers were examined to see the relationship between the increase in average annual temperature, flowering time, and flower count.

Global Change Drivers Synergize With The Negative Impacts Of Non-Native Invasive Ants On Native Seed-Dispersing Ants, Robert Warren

Biology Faculty Datasets

Non-native species invasion, habitat fragmentation and climate change individually impose negative impacts on natural systems, but their synergistic effects may do more harm than the sum of their parts. We examined the combined effects of these global change drivers by studying the impacts of experimental warming on seed-dispersing forest ant nesting and foraging in the Southeastern U.S. to determine if warming and forest fragmentation facilitated non-native ant invasion effects on native ants. Spring ant phenology and activities were monitored for two years (2019-2020) at weekly bait stations and in artificial nest occupancy. We found that, when combined, forest edge habitat …

Effects Of Elevated Temperature, Reduced Hydroperiod, And Invasive Bullfrog Larvae On Pacific Chorus Frog Larvae, Bailey R. Tasker, Karli Honebein, Allie M. Erickson, Julia E. Misslin, Paul Hurst, Sarah Cooney, Skylar Riley, Scott A. Griffith, Betsy A. Bancroft

Biology Faculty Scholarship

Climate change and invasive species threaten many ecosystems, including surface freshwater systems. Increasing temperatures and reduced hydroperiod due to climate change may promote the persistence of invasive species and facilitate new invasions due to potentially higher tolerance to environmental stress in successful invaders. Amphibians demonstrate high levels of plasticity in life history characteristics, particularly those species which inhabit both ephemeral and permanent water bodies. We tested the influence of two projected effects of climate change (increased temperature and reduced hydroperiod) on Pacific chorus frog (Pseudacris regilla) tadpoles alone and in combination with the presence of tadpoles of a …

Quantifying Crop Phenology For Food Sustainability Under Climate Change: Integration Of Remote Sensing, Machine Learning, And Ecosystem Modeling, Yanjun Yang

Theses and Dissertations--Plant and Soil Sciences

Climate change is projected to continue and accelerate significantly in the future if global greenhouse gas emissions are not curbed. Previous studies have shown that crop growth and production in agroecosystems are primarily determined by the weather conditions over the growing season. Crop phenology represents one of the most critical indicators in determining crop yield and adjusting the adaptation of crops to climate change. It provides essential information for monitoring and modeling crop growth dynamics and productivity. Therefore, understanding and quantifying the impacts of climate change on crop phenology and then agricultural production is crucial to formulate feasible climatic adaptation …

The Influence Of Burn Severity On Post-Fire Spectral Recovery Of Three Fires In The Southern Rocky Mountains, Jaclyn Guz, Florencia Sangermano, Dominik Kulakowski

Geography

Increased wildfire activity and altered post-fire climate in the Southern Rocky Mountains has the potential to influence forest resilience. The Southern Rocky Mountains are a leading edge of climate change and have experienced record-breaking fires in recent years. The change in post-fire regeneration and forest resilience could potentially include future ecological trajectories. In this paper, we examined patterns of post-fire spectral recovery using Landsat time series. Additionally, we utilized random forest models to analyze the impact of climate and burn severity on three fire events in the Southern Rocky Mountains. Fifteen years following the fires, none of the burned stands …

Applying Landscape Fragmentation Analysis To Icescape Environments: Potential Impacts For The Pacific Walrus (Odobenus Rosmarus Divergens), Anthony Himmelberger, K E. Frey, Florencia Sangermano

Geography

Sea-ice cover across the Arctic has declined rapidly over the past several decades owing to amplified climate warming. The Pacific walrus (Odobenus rosmarus divergens) relies on sea-ice floes in the St. Lawrence Island (SLI) and Wainwright regions of the Bering and Chukchi seas surrounding Alaska as a platform for rest, feeding and reproduction. Lower concentrations of thick ice floes are generally associated with earlier seasonal fragmentation and shorter annual persistence of sea-ice cover, potentially affecting the life history of the Pacific walrus. In this study, 24 Landsat satellite images were classified into thick ice, thin ice or open water to …

The Nexus Of Climate Change, Biodiversity, And Food Security: A Brazil Case Study, Andrew M. Berger

Dissertations and Theses

What is referred to as climate change today is the rapid warming of the climate, largely from human actions, and the effects that come with that warming. One study published by the United States Department of Agriculture (USDA) in 2021 argues that, “human-induced emissions of greenhouse gases have caused increases in global average temperatures, changes in precipitation timing and intensity, rising sea levels, and many other changes.” A Food and Agriculture Organization (FAO) study found that when looking at the number of countries exposed to climate extremes in five year periods from 2000 to 2020, the number of countries “exposed …

Genetically Engineered Food, Food Security, And Climate Change, Joanna K. Sax

Faculty Scholarship

Malnutrition is the leading cause of death and disease worldwide. Climate change is an existential crisis. We need to feed people and address the role of agriculture in climate change – at the same time. This is problematic, as agriculture inherently creates issues that contributes to climate change. Utilizing science, through genetically engineered crops, is one way to close the harm gap between food security and climate change. This essay addresses the controversial issue of genetically engineered crops with the complicated issues of food security and climate change by analyzing three main issues: (1) how the science of genetically engineered …

Temperature-Dependent Sex Determination (Tsd): Implications For The Biology And Conservation Of The Kemp's Ridley Sea Turtle (Lepidochelys Kempii), Katherine Presz

All ETDs from UAB

The Kemp’s ridley sea turtle (Lepidochelys kempii) has temperature-dependent sex determination (TSD) where the incubation temperature of the egg determines the sex of the hatchling. This has significant implications for the ecology, evolution, and conservation of this species because it can affect sex ratios. The studies presented in this thesis address hatchling sex ratios produced in Kemp’s ridley conservation programs using both natural as well as manipulated incubation regimes. First, a histology-based study was utilized to investigate sex ratios produced at the Padre Island National Seashore from 2002-2019. The results indicate that a female bias has been produced each year …

Removing Carbon Dioxide Through Artificial Upwelling And Downwelling: Legal Challenges And Opportunities, Romany M. Webb, Korey Silverman-Roati, Michael B. Gerrard

Faculty Scholarship

A 2022 report by the Intergovernmental Panel on Climate Change warned that, to keep global average temperatures within 1.5oC above pre-industrial levels, emissions must reach net-zero by mid-century. The report concluded that achieving net-zero emissions will require the removal of carbon dioxide from the atmosphere “to counterbalance hard-to-abate emissions” from sectors like agriculture, aviation, and shipping. The report further noted that, if deployed at large scales, carbon dioxide removal (“CDR”) could also be used to achieve net negative emissions and thus effectively reduce the atmospheric concentration of carbon dioxide.

A variety of CDR techniques, both terrestrial and ocean-based, have been …

Marx, Critical Theory, And The Treadmill Of Production Of Value: Why Environmental Sociology Needs A Critique Of Capital, Alex Stoner

Journal Articles

This chapter explores the domestication of Marx’s critique of political economy within Marxist-oriented environmental sociology, and treadmill of production (ToP) theory, in particular. The aim is to explicate the theoretical resources for a rigorous critique of capital-induced planetary degradation. Shortcomings of ToP theory pertaining to the conceptualization of capital and value are identified. The reasons for these shortcomings, including how they might be addressed, are elaborated by reconsidering key aspects of Marx’s critical theory of modern capitalist society. The chapter contributes to current discussions in both critical theory and environmental sociology by demonstrating the continued relevance of Marx’s critical theory …

Air Pollution As Public Nuisance: Comparing Modern-Day Greenhouse Gas Abatement With Nineteenth-Century Smoke Abatement, Kate Markey

Michigan Law Review

Public nuisance allows plaintiffs to sue actors in tort for causing environmental harm that disrupts the public’s use and enjoyment of the land. In recent years, state and local governments have filed public nuisance actions against oil companies, hoping to hold them responsible for the harm of climate change. Since no plaintiff has prevailed on the merits so far, whether these lawsuits are worth bringing, given the other legal avenues available, remains an open question. This Comment situates these actions in their appropriate historical context to show that these lawsuits are neither unprecedented nor futile. In particular, it examines the …

Genetic Rescue Of Isolated Cutthroat Trout, Donovan Alexander Bell

Graduate Student Theses, Dissertations, & Professional Papers

Anthropogenic habitat destruction has isolated innumerable populations that now face increased extinction risk due to demographic and genetic factors. Although often the best strategy, restoring connectivity can be challenging or even harmful. Such is the case for westslope cutthroat trout (Oncorhynchus clarkii lewisi; WCT) in the Missouri River basin, which are limited to completely isolated populations. Nonnative species threaten WCT in connected watersheds and barrier removal could be detrimental. My dissertation examines trade-offs and strategies for the management of isolated WCT. I first examined how nonnative trout species and climate change influence the distribution of WCT using a multispecies, dynamic …

Combined Effects Of Temperature And Heavy Metals On The Performance Of The Giant Salmonfly., James Frakes, Amanda Andreas, Benjamin P. Colman, Aurthur Woods

Graduate Student Theses, Dissertations, & Professional Papers

In many freshwater ecosystems, communities of aquatic insects are facing the combined stresses of warmer waters due to climate change and increased exposure to heavy metal toxicants. Although each stressor may threaten aquatic insects independently, they also likely interact in important ways to affect insect physiology and performance. Here we investigate this potential interaction using two populations of aquatic nymphs of the giant salmonfly, Pteronarcys californica, collected from adjacent rivers in Montana: naïve individuals from Rock Creek, a relatively pristine stream, and individuals from the Upper Clark Fork River, which has a history of heavy metal pollution and higher …

Growing Tiny Plants In Common Environments: Assessing Patterns And Mechanisms Of Drought Response Within Species, Mariah Kathryn Mcintosh

Graduate Student Theses, Dissertations, & Professional Papers

As climate changes and drought frequency and intensity increases, understanding how plants respond will be critical both for predicting potential for adaptation to future climate and for implementing effective ecosystem conservation and management at a time of rapid change. However, gaps in knowledge about the extent to which species vary in key traits across their ranges and the evolutionary and physiological mechanisms which underlie this variation limits both theoretical understanding and effective management. The broad theme of this dissertation is to address within-species variation both to improve understanding of adaptation to future climate and inform ecosystem conservation and management. The …

Drought, Tree Mortality, And Regeneration In Northen California, Sophia Lb Lemmo

Cal Poly Humboldt theses and projects

The 2012-2016 California drought was the most severe in the state’s recorded history, contributing to the death of millions of trees. While the effects of this drought on forests are relatively well studied in the central and southern Sierra Nevada, less is known about its effects on the heavily timbered and diverse forests of northern California. Through sampling 54 0.25 ha plots in northern California, this study compared tree mortality and regeneration patterns before, during, and after California’s most recent record-setting drought. This study evaluated 1) the influence of habitat and competitive covariates on mortality and regeneration trends using ridge …

Evaluation Of Tidal Fresh Forest Distributions And Tropical Storm Impacts Using Sentinel-2 Msi Imagery, Galen Costomiris

College of Graduate Studies: Theses & Dissertations

Situated in the transitional zone between non-tidal forests upstream and tidal fresh marshes downstream, tidal fresh forests occupy a unique and increasingly precarious habitat. The threat of intensifying anthropogenic climate change, compounded by the effects of historical logging and drainage alterations, could reduce the extent of this valuable ecosystem. The overall goals of this project were to identify forest communities present in the Altamaha tidal fresh forest; develop satellite imagery-based classifications of tidal fresh forest and tidal marsh vegetation along the Altamaha River, Georgia; and to quantify changes in vegetation distribution in the aftermath of hurricanes Matthew and Irma. Based …

Biological Sciences Faculty Publications

Marine species and ecosystems are widely affected by anthropogenic stressors, ranging from pollution and fishing to climate change. Comprehensive assessments of how species and ecosystems are impacted by anthropogenic stressors are critical for guiding conservation and management investments. Previous global risk or vulnerability assessments have focused on marine habitats, or on limited taxa or specific regions. However, information about the susceptibility of marine species across a range of taxa to different stressors everywhere is required to predict how marine biodiversity will respond to human pressures. We present a novel framework that uses life-history traits to assess species’ vulnerability to a …

Environmental Socialization In College: A Survey Research And Network Analysis Of Changes In Climate-Conscious Concerns And Behaviors, Bijeta Lamichhane

Senior Independent Study Theses

Studies have established that socialization takes place in different stages of life. This study explores how political socialization occurs at The College of Wooster by examining changes in students' political identities as well as their perceptions towards a politicized issue, that is, climate change. These shifts in beliefs and concerns among students were evaluated by implementing quantitative research tools present in the Statistical Package for Social Sciences (SPSS) and constructing a similarity network using Gephi to explore similarities across students at this institution. The results revealed that students have become more liberal after joining this college. The study also found …

New Research And Wild Horse And Burro Management, David Jenkins

Human–Wildlife Interactions

In the United States, the Wild Free-Roaming Horses and Burros Act (WFRHBA) gave the Bureau of Land Management (BLM) and the U.S. Forest Service the statutory obligation to manage and protect free-roaming equids (i.e., wild horses [Equus ferus] and burros [E. asinus]) on designated management areas on public land. The WFRHBA was intended to ensure that wild horses and burros on the public lands exist in self-sustaining herds in perpetuity, alongside other congressionally mandated, multiple uses of public lands. The BLM recently published a strategic research plan for their wild horse and burro program. The research …

Impacts Of Changing Permafrost Conditions On Vegetation Productivity In The Northern Boreal Forest, Emily Ogden

Theses and Dissertations (Comprehensive)

Vegetation productivity across the boreal forest has increased over the past several decades. However, at a regional scale there is large variation from increased (greening) to decreased (browning) productivity and large areas with no measured change. Some of this variation can be explained by disturbances, such as wildfire, or by increased climate variability. In northern regions underlain by permafrost, the interactions between climate, disturbance, and vegetation productivity may be more complex. For my thesis, I used a time-series of ground thermal data from permafrost monitoring sites established by the Geological Survey of Canada along a latitudinal transect of the Northwest …

Constitutional Authority, Common Resources, And The Climate, Anthony Moffa

Utah Law Review

History, text, and precedent reveal an understudied and underutilized source of constitutional authority for environmental protection—the Property Clause of Article IV, Section 3. The Clause vests Congress with the “Power to dispose of and make all needful Rules and Regulations respecting the Territory or other Property belonging to the United States.” This work re-examines these words, the context in which they were written, and the limited judicial decisions interpreting them with an eye towards increased congressional reliance on the Property Clause in the face of daunting threats to our natural environment. Much prior scholarly explanation of the Property Clause focused …

Common Garden Study Reveals Frost-Tolerant, Generalist Northern Seed Sources Are Best Suited To Expand Range Of Quercus Rubra, Emily Lindback

Dissertations, Master's Theses and Master's Reports

Climate change is shifting the potential suitable range of northern red oak (Quercus rubra L.) faster than it can migrate, creating an adaptation lag. Quercus rubra is prominent in eastern North American forests and important for its carbon sequestration, ecological roles, and economic significance. Our study addresses which populations of Q. rubra are best suited for climatic conditions at the northern and central range limits. Our findings can inform forestry management policies such as assisted migration, where species are transferred within their native range to mitigate the effects of climate change. We planted over 800 Q. rubra seedlings …

Differential Water-Use And Growth Responses Of Pinus Densiflora And Larix Kaempferi Seedlings To Microclimate Manipulation, Jiae An, Hanna Chang, Seung Hyun Han, Asia Khamzina, Yowhan Son

Turkish Journal of Agriculture and Forestry

Our study assessed how physiological traits and the growth of seedlings of Pinus densiflora and Larix kaempferi, representative coniferous species of Korea, are affected by warming and precipitation manipulation. A warming and precipitation manipulation experiment was conducted with 1- and 2-year-old seedlings using infrared heaters, transparent panels, and an irrigation system. Plant physiological activities were monitored using a portable photosynthesis measurement system, and seedling growth was investigated by measuring the dry weight of harvested biomass. P. densiflora, an isohydric species, showed an overall decrease in physiological activities under the warming treatment in the first (germination) year. In particular, stomatal conductance …

Editorial: Fire Regimes In Desert Ecosystems: Drivers, Impacts And Changes, Eddie J. B. Van Etten, Matthew L. Brooks, Aaron C. Greenville, Glenda M. Wardle

Research outputs 2022 to 2026

Although not commonly associated with fire, many desert ecosystems across the globe do occasionally burn, and there is evidence that fire incidences are increasing, leading to altered fire regimes in this biome. The increased prevalence of megafires (wildfires > 10,000 ha in size and typically damaging) in most global biomes is linked to climate change, although those occurring in deserts have received far less attention, from both a research and policy perspective, than that of forested ecosystems (Linley et al., 2022). Understanding the drivers of desert fires, from climate to landscape patterns of hydrology and soil, and how these may be …

Tropicalization Of Seagrass Macrophytodetritus Accumulations And Associated Food Webs, Gilles Lepoint, Glenn A. Hyndes

Research outputs 2022 to 2026

Seagrass, systems export significant amounts of their primary production as large detritus (i.e. macrophytodetritus). Accumulations of exported macrophytodetritus (AEM) are found in many areas in coastal environment. Dead seagrass leaves are often a dominant component of these accumulations, offering shelter and/or food to numerous organisms. AEM are particular habitats, different from donor habitats (i.e. seagrass meadow, kelp or macroalgae habitats) and with their own characteristics and dynamics. They have received less attention than donor habitats despite the fact they often connect different coastal habitats, are the place of intense remineralization processes and shelter associated detritus food web. As for seagrass …

The Influence Of Rising Atmospheric Co2 On Grassland Ecosystems, J. A. Morgan, P. C. D. Newton, J. Nösberger, C. E. Owensby

IGC Proceedings (1977-2023)

Increasing atmospheric CO₂ concentrations and climatic change will have significant effects on the ecology of grasslands. This paper evaluates results from four CO₂ enrichment studies in contrasting grasslands. A Swiss study investigates the effects of elevated CO₂ (600 μL L^-1 CO₂) on perennial ryegrass (Lolium perenne L.) and white clover (Trifolium repens L), a New Zealand study examines how elevated CO₂ (475 μL L^-1 CO₂) affects a botanically diverse pasture, and studies in the Kansas tallgrass prairie and the Colorado shortgrass steppe investigate the effects of an approximate …

Application Of Competitive Intelligence For Insular Territories: Automatic Analysis Of Scientific And Technology Trends To Fight The Negative Effects Of Climate Change, Henri Dou, Pierre Fournie
