Effects Of Ocean Acidification On Early Life History Stages Of Caribbean Scleractinian Corals, Rebecca Albright

Open Access Dissertations

Ocean acidification (OA) refers to the increase in acidity (decrease in pH) of the ocean’s surface waters resulting from oceanic uptake of atmospheric carbon dioxide (CO2). Mounting experimental evidence suggests that OA threatens numerous marine organisms, including reef-building corals; however, few studies have focused on the effects on early life history stages. Coral recruitment is critical to the persistence and resilience of coral reefs and is regulated by several early life processes, including: larval availability (gamete production, fertilization, etc.), larval settlement, post-settlement growth, and survival. Environmental factors that disrupt these early life processes can result in compromised or failed recruitment …

Macro-Risks: The Challenge For Rational Risk Regulation, Michael P. Vandenbergh, Jonathan A. Gilligan

Vanderbilt Law School Faculty Publications

Drawing on the recent financial crisis, we introduce the concept of macro-risk. We distinguish between micro-risks, which can be managed within conventional economic frameworks, and macro-risks, which threaten to disrupt economic systems so much that a different approach is required. We argue that catastrophic climate change is a prime example of a macro-risk. Research by climate scientists suggests disturbingly high likelihoods of temperature increases and sea level rises that could cause the kinds of systemic failures that almost occurred with the financial system. We suggest that macro-risks should be the principal concern of rational risk assessment and management, but they …

Developing Methods To Assess The Potential Effects Of Global Climate Change On Deer Creek Reservoir Using Water Quality Modeling, Reed Earl Chilton

Theses and Dissertations

To evaluate the potential impacts of future climate change on a temperate reservoir, I used a calibrated water quality and hydrodynamic model validated using three years of data (2007-2009) from Deer Creek Reservoir (Utah). I evaluated the changes due to altered air temperatures, inflow rates, and nutrient loads that might occur under Global Climate Change (GCC). I developed methods to study GCC on reservoirs. I produced Average Water Temperature Plots, Stratification Plots, and Total Concentration Plots. Average Water Temperature Plots show the sensitivity of the water temperature to various parameters. Stratification Plots quantify stratification length and strength as well as …

Engaging Chicago Residents In Climate Change Action: Results From Rapid Ethnographic Inquiry, Lynne M. Westphal, Jennifer L. Hirsch

Cities and the Environment (CATE)

Addressing climate change requires action at all levels of society, from neighborhood to international levels. Using Rapid Ethnography rooted in Asset Based Community Development theory, we investigated climate-friendly attitudes and behaviors in two Chicago neighborhoods in order to assist the City with implementation of its Climate Action Plan. Our research suggests a means to effectively engage urban residents at the household and neighborhood level: understand the issues of importance in each neighborhood, assess the ways these are related to climate change mitigation or adaptation actions, and engage residents from this perspective, meeting mutually compatible goals. This builds upon the concept …

Tropical Street Trees And Climate Uncertainty In Southeast Asia, Roger Kjelgren, Yongyut Trisurat, Ladawan Puangchit, Nestor Baguinon, Puay Tan Yok

Plants, Soils, and Climate Faculty Publications

Urban trees are a critical quality of life element in rapidly growing cities in tropical climates. Tropical trees are found in a wide variety of habitats governed largely by the presence and duration of monsoonal dry periods. Tropical cities can serve as a proxy for climate change impacts of elevated carbon dioxide (CO2), urban heat island, and drought-prone root zones on successful urban trees. Understanding the native habitats of species successful as tropical urban trees can yield insights into the potential climate impact on those habitats. Species from equatorial and montane wet forests where drought stress is not a limiting …

Bats Of Mesa Verde National Park, Colorado: Composition, Reproduction, And Roosting Habits, Thomas J. O'Shea, Paul M. Cryan, E. Apple Snider, Ernest W. Valdez, Laura E. Ellison, Daniel J. Neubaum

Monographs of the Western North American Naturalist

We determined the bat fauna at Mesa Verde National Park (Mesa Verde) in 2006 and 2007, characterized bat elevational distribution and reproduction, and investigated roosting habits of selected species. We captured 1996 bats of 15 species in mist nets set over water during 120 nights of sampling and recorded echolocation calls of an additional species. The bat fauna at Mesa Verde included every species of bat known west of the Great Plains in Colorado, except the little brown bat (Myotis lucifugus). Some species showed skewed sex ratios, primarily due to a preponderance of males. Thirteen species of bats …

Climate Change And San Francisco Bay-Delta Tidal Wetlands, V Thomas Parker, John Callaway, Lisa M. Schile, Michael C. Vasey, Ellen R. Herbert

Environmental Science

Climate change will affect tidal wetlands with higher rates of sea-level rise and higher concentrations of salt in brackish and freshwater tidal systems, in addition to causing increases in atmospheric CO2 concentration, warmer temperatures, and shifts in precipitation. In the San Francisco Bay–Delta, the areas most likely to be affected—brackish and freshwater tidal wetlands—are also the sites with the majority of endemic plant species and the greater biodiversity and productivity. Effects on the San Francisco Bay– Delta estuary are complex and difficult to predict, but a few things are clear. Biodiversity of the tidal wetland system in the San Francisco …

Plant Species Vulnerability To Climate Change In Peninsular Thailand., Y. Trisuart, S. Fajendra, Roger K. Kjelgren

CWEL Publications

The objective of this research study was to evaluate the consequences of climate change on shifts in distributions of plant species and the vulnerability of the species in Peninsular Thailand. A sub-scene of the predicted climate in the year 2100, under the B2a scenario of the Hadley Centre Coupled Model, version 3 (HadCM3), was extracted and calibrated with topographic variables. A machine learning algorithm based on the maximum entropy theory (Maxent) was employed to generate ecological niche models of 66 forest plant species from 22 families. The results of the study showed that altitude was a significant factor for calibrating …

Inter-Colony Comparison Of Diving Behavior Of An Arctic Top Predator: Implications For Warming In The Greenland Sea, Nina J. Karnovsky, Zachary W. Brown '07, Jorg Welcker, Ann M.A. Harding, Wojciech Walkusz, André Cavalcanti, Johanna S. Hardin, Alexander Kitaysky, Geir Gabrielsen, David Grémillet

Pomona Faculty Publications and Research

The goal of this study was to assess how diverse oceanographic conditions and prey communities affect the foraging behavior of little auks Alle alle. The Greenland Sea is characterized by 3 distinct water masses: (1) the East Greenland Current (EGC), which carries Arctic waters southward; (2) the Sørkapp Current (SC), which originates in the Arctic Ocean but flows north along the west coast of Spitsbergen; and (3) the West Spitsbergen Current (WSC), which carries warm Atlantic-derived water north. Each of these 3 water masses is characterized by a distinct mesozooplankton community. Little auks breeding adjacent to the EGC have …

Colorado's Large Snow Events' Impact On Tree Ring Growth And Dillon Reservoir, Katrina Leona Marzetta

Electronic Theses and Dissertations

Meteorological observations from 1894 through 2010 suggest that 17 historically large snow events occurred in the mountains of Colorado within Denver's water supply region. Of these 16 events, 14 can be identified in precipitation sensitive tree ring records as positive climatic pointer years. If these storms were to occur today, they would have the potential to fill reservoirs in Denver Water's supply system, even after years of sustained drought. These "drought busters" have the potential to refill Dillon Reservoir by increasing average yearly inflow up to 146% of the previous year's inflow. Such drought busters can help Denver recover from …

Causes Of Rarity In Glade-Endemic Plants: Implications For Responses To Climate Change, Nicole Miller-Struttmann

All Theses and Dissertations (ETDs)

This dissertation documents the relationship between stress-adaptation and reproductive specialization in three endemic plant species: Delphinium treleasei, Echinacea paradoxa, and Scutellaria bushii) that are locally abundant but restricted to stressful habitats and their closely-related congeners: D. carolinianum, E. pallida, S. ovata, and S. parvula) that have broader habitat use, including hot, xeric habitats. In Chapter Two, I test two hypotheses concerning reproductive specialization in endemic plants and their common congeners: CC). I quantify morphological traits that are associated with stress-adaptation and reproductive specialization, pollinator behavior, and reproductive specialization. The locally abundant, habitat specialist: LAHS) species were significantly different from their …

The Potential For Indicators In The Management Of Climate Change Impacts On Cultural Heritage, Caithleen Daly

Conference papers

The global scale and unpredictable nature of climate change impacts on cultural heritage poses a challenge for conservation management. This article explores the potential of indicators as an aid for decision makers in the heritage sector. The author proposes a new indicator tool for addressing long-term stone recession impacts that may be related to climate change. The indicator is being installed at two World Heritage sites in Ireland but no results are available. The prototype was developed during doctoral research at the Technological University of Dublin.

Strategies For Conserving Forest Genetic Resources In The Face Of Climate Change, John Bradley St.Clair, Glenn Thomas Howe

Turkish Journal of Botany

Conservation of genetic diversity is important for continued evolution of populations to new environments, as well as continued availability of traits of interest in genetic improvement programs. Rapidly changing climates present new threats to the conservation of forest genetic resources. We can no longer assume that in situ reserves will continue to preserve existing genetic diversity. Management of reserves should become more active. In some reserves, existing genetic diversity should be preserved by creating stands that are more resistant to threats using silvicultural treatments such as thinning and prescribed burning. In other reserves, natural selection and adaptation to changed environments …

A Tradable Conservation Easement For Vulnerable Conservation Objectives, W. William Weeks

Articles by Maurer Faculty

The critical conservation objectives in some conservation easements will probably be compromised by the effects of climate change in the relatively near future. Prompted to consider that likelihood, we can similarly predict that landscape fragmentation, invasive species, and other catastrophes— anthropogenic and natural—may also seriously diminish the capacity of particular parcels of land to serve narrowly defined conservation purposes, and especially, the conservation of a particular element of biodiversity.

Winter And Summer Upwelling Modes And Their Biological Importance In The California Current Ecosystem, Bryan A. Black, Isaac D. Schroeder, William J. Sydeman, Steven J. Bograd, Brian K. Wells, Franklin B. Schwing

United States Department of Commerce: Staff Publications

Analysis of monthly coastal upwelling intensities revealed two seasonal and biologically relevant upwelling ‘modes’ in the California Current Ecosystem (CCE). The first mode reflected upwelling during the summer months and was characterized by low-frequency (multidecadal) processes, including significant (Po0.01) linear trends at some latitudes. In contrast, the second mode reflected wintertime upwelling and was defined by higher-frequency variability associated with the North Pacific High and El Niño Southern Oscillation events. These modes were compared with multidecadal time series of splitnose rockfish (Sebastes diploproa) otolith growth, yelloweye rockfish (S. ruberrimus) otolith growth, Chinook salmon (Oncorhynchus tshawytscha …

Synthesis Of Climate Change Policy In Judicial, Executive, And Legislative Branches Of U.S. Government, Robert Brinkmann, Sandra J. Garren

School of Geosciences Faculty and Staff Publications

In recent years, the United States has struggled to develop a comprehensive policy for climate change and concomitant greenhouse gas emissions that addresses the current scientific thinking on the topic. The absence of any clear legislative or executive approach dominated national discussions and the court system was used to litigate a variety of issues associated with global warming. This paper synthesizes actions taken in the three branches of government prior to and immediately following the Obama election. In the Judicial branch, several branches of law have been used to force government and private parties to reduce greenhouse gas emissions. Based …

Flowering Phenology Change And Climate Warming In Southwestern Ohio, Ryan Mcewan, Robert J. Brecha, Donald R. Geiger, Grace P. John

Biology Faculty Publications

Global surface temperature has increased markedly over the last 100 years. This increase has a variety of implications for human societies, and for ecological systems. One of the most obvious ways ecosystems are affected by global climate change is through alteration of organisms’ developmental timing (phenology). We used annual botanical surveys that documented the first flowering for an array of species from 1976 to 2003 to examine the potential implications of climate change for plant development. The overall trend for these species was a progressively earlier flowering time. The two earliest flowering taxa (Galanthus and Crocus) also exhibited the strongest …

A Tale Of Two Carbon Sinks: Can Forest Carbon Management Serve As A Framework To Implement Ocean Iron Fertilization As A Climate Change Treaty Compliance Mechanism?, Randall S. Abate

Journal Publications

Any post-Kyoto climate change treaty regime must seek to fully engage the use of carbon sinks to complement emissions reduction measures in order to comply with the treaty's mandates. The Kyoto Protocol did not include avoided deforestation as a mechanism for earning emission reduction credits. However, reducing emissions from deforestation and degradation (REDD) quickly gained popularity as a viable climate change compliance strategy in the period immediately preceding the negotiations at the Fifteenth Conference of the Parties (COP 15) in Copenhagen in 2009. The Copenhagen Accord is replete with references to REDD as a focus for the international community's progression …

Solar Energy Development On The Federal Public Lands: Environmental Trade-Offs On The Road To A Lower-Carbon Future, Robert L. Glicksman

GW Law Faculty Publications & Other Works

The federal government has endorsed more extensive use of the federal public lands for the production of solar power, both to reduce the greenhouse gas emissions that contribute to climate change and to bolster the security of domestic energy supplies. Spurred by grant money made available under the American Recovery and Reinvestment Act of 2009, the Bureau of Land Management (BLM) in 2010 approved nine utility-scale solar projects on public lands in California and Nevada. These projects were designed to avoid adversely affecting the habitats of endangered and threatened species that frequent the desert southwest and cultural resources important to …

Graduate Student Theses, Dissertations, & Professional Papers

Global climate change is expected to have adverse impacts on the Rocky Mountain West, including impacts on water and land use, energy consumption, weather patterns, and wildlife stewardship. The State of Montana, Missoula County and the City of Missoula all have recognized these threats and are taking steps to address climate change impacts. In response to the unique challenges posed by urban environments, the practice of green, or vegetative, roofing has been promoted through policy measures by a number of cities in the United States and abroad. This project explores green roofing and the policies used to encourage the practice …

Causes And Consequences Of Changes In Algal Community Structure Of Arctic Tundra Ponds From Barrow, Alaska, Mariana Vargas Medrano

Open Access Theses & Dissertations

Algal communities in the Arctic are highly sensitive to environmental change, such as longer growing seasons and changes in ice cover. On the north slope of Alaska, ponds and lakes cover large portions of the total land area. We surveyed the periphytic algal communities in tundra ponds from Barrow, Alaska to assess environmental effects on their populations. Samples were collected in August 2008-10 from two main study areas: the IBP (the International Biological Program), which was also studied in 1970-71 but now is located near to human settlements, and the BEO (Barrow Environmental Observatory), which is within a protected area. …
