Keep Up Or Drown: Adjustment Of Western Pacific Coral Reefs To Sea-Level Rise In The 21st Century, Robert Van Woesik, Yimnang Golbuu, George Roff

Ocean Engineering and Marine Sciences Faculty Publications

Since the Mid-Holocene, some 5000 years ago, coral reefs in the Pacific Ocean have been vertically constrained by sea level. Contemporary sea-level rise is releasing these constraints, providing accommodation space for vertical reef expansion. Here, we show that Porites microatolls, from reef-flat environments in Palau (western Pacific Ocean), are ‘keeping up’ with contemporary sea-level rise. Measurements of 570 reef-flat Porites microatolls at 10 locations around Palau revealed recent vertical skeletal extension (78±13 mm) over the last 6–8 years, which is consistent with the timing of the recent increase in sea level. We modelled whether microatoll growth rates will potentially ‘keep …

© 2015 Elsevier Inc. Advances in nucleic acid sequencing technology are removing obstacles that historically prevented use of genomics within ocean change biology. As one of the first marine calcifiers to have its genome sequenced, purple sea urchins (Strongylocentrotus purpuratus) have been the subject of early research exploring genomic responses to ocean acidification, work that points to future experiments and illustrates the value of expanding genomic resources to other marine organisms in this new 'post-genomic' era. This review presents case studies of S. purpuratus demonstrating the ability of genomic experiments to address major knowledge gaps within ocean acidification. Ocean acidification …

Climate Change: Leveraging Legacy, Michael P. Vandenbergh, Kaitlin T. Raimi

Vanderbilt Law School Faculty Publications

This Article explores whether a private governance initiative can harness
legacy concerns to address climate change. The socio-temporal trap is an
important barrier to climate change mitigation: The costs of reducing carbon
emissions will be incurred by this generation, but most of the benefits will
accrue to future generations. Research suggests that social influences—
including concerns about legacy—can induce individuals to overcome
collective action problems, but individuals know that future generations will
not have information about who acted today in ways meriting social sanctions
or rewards. Insufficient information may undermine three aspects of legacy-
driven behavior: the concern about how …

Morphometry And Average Temperature Affect Lake Stratification Responses To Climate Change, Benjamin Kraemer, Orlane Anneville, Sudeep Chandra, Margaret Dix, Esko Kuusisto, David M. Livingstone, Alon Rimmer, S. Geoffrey Schladow, Eugene Silow, Lewis M. Sitoki, Rashid Tamatamah, Yvonne Vadeboncoeur, Peter B. Mcintyre

Biological Sciences Faculty Publications

Climate change is affecting lake stratification with consequences for water quality and the benefits that lakes provide to society. Here we use long-term temperature data (1970–2010) from 26 lakes around the world to show that climate change has altered lake stratification globally and that the magnitudes of lake stratification changes are primarily controlled by lake morphometry (mean depth, surface area, and volume) and mean lake temperature. Deep lakes and lakes with high average temperatures have experienced the largest changes in lake stratification even though their surface temperatures tend to be warming more slowly. These results confirm that the nonlinear relationship …

Recovering From The Recovery Narrative: On Globalism, Green Jobs And Cyborg Civilization, Michael Burger

Akron Law Review

In this Essay, I make a preliminary foray into this new narrative terrain, identifying several emerging legal storylines that have arisen in the wake of climate change disruptions and that I predict will prove influential in the coming years. In Part I, I discuss the ways in which new perceptions of scale are re-defining human beings’ attachments to a sense of “place” or “dwelling” and are shaping new attitudes about what constitutes the local, posing potential problems for existing federalism schemes. In Part II, I discuss the ways in which America’s long history of nationalizing nature manifests in the discourse …

Replacing Sustainability, Robin Kundis Craig, Melinda Harm Benson

Akron Law Review

This Article argues that, from a policy perspective, we must face the impossibility of even defining—let alone pursuing—a goal of “sustainability” in a world characterized by such extreme complexity, radical uncertainty, and discomfiting loss of stationarity. Instead, we need new policy directions and orientations that provide the necessary capacity to deal with these “wicked problems” in a meaningful and equitable way. The realities of current and emerging SES dynamics warrant a new set of tools and approaches to governance of those systems. Part II of this Article provides a brief history of sustainability and sustainable development, including corollary emphases on …

Heterotrophy And Lipids As Indicators Of Resilience To Climate Change Stress In Scleractinian Corals, Erica K. Towle

Open Access Dissertations

Coral reefs are biodiverse ecosystems with high biological, cultural, economic, and recreational value that are facing multiple anthropogenic stressors, the greatest of which is global climate change via warming and ocean acidification (OA). Increased warming throughout the century may reach a point where frequent bleaching, the expulsion of corals’ symbiotic algae that can provide the coral with over 90% of its daily metabolic requirements, may cause widespread mortality. OA, a result of increased carbon dioxide dissolving into seawater, changes the chemistry of seawater such that the pH of the ocean becomes more acidic. This decrease in pH is accompanied by …

Contrasting Environmental Drivers Of Adult And Juvenile Growth In A Marine Fish: Implications For The Effects Of Climate Change, Joyce Jia Lin Ong, Adam Nicholas Rountrey, Jessica Jane Meeuwig, Stephen J. Newman, Jens Zinke, Mark Gregory Meekan

Fisheries Research Articles

Many marine fishes have life history strategies that involve ontogenetic changes in the use of coastal habitats. Such ontogenetic shifts may place these species at particular risk from climate change, because the successive environments they inhabit can differ in the type, frequency and severity of changes related to global warming. We used a dendrochronology approach to examine the physical and biological drivers of growth of adult and juvenile mangrove jack (Lutjanus argentimaculatus) from tropical north-western Australia. Juveniles of this species inhabit estuarine environments and adults reside on coastal reefs. The Niño-4 index, a measure of the status of …

Environmental And Adaptive Buffers That Mediate The Response Of Subalpine Ecosystems To Environmental Change, Lafe G. Conner

Student Works

This document reports the results of 4 studies of subalpine ecosystem ecology, describing ways that spatial heterogeneity in soils and plant communities mediate ecosystem responses to environmental change. Ecosystem responses to environmental change are also mediated by regional climate patterns and interannual variability in weather. In the first chapter we report the results of an experiment to test for the mediating effects of associational resistance in a forest community that experienced wide-spread beetle kill. We found that Engelmann spruce were more likely to survive a beetle outbreak when growing in low densities (host dilution) and not through other types of …

Energy In The Ecopolis, Sara C. Bronin

Cornell Law Faculty Publications

Climate change, resource scarcity, and environmental degradation demand a paradigm shift in urban development. Currently, too many of our cities exacerbate these problems: they pollute, consume, and process resources in ways that negatively impact our natural world. Cities of the future must make nature their model, instituting circular metabolic processes that mimic, embrace, and enhance nature. In other words, a city must be a regenerative city or, as some say, an “ecopolis.” So, how to get there—to ecopolis—from here? In this Comment, I propose a partial answer by focusing on certain legal frameworks that must be reenvisioned to enable the …

Too Many Cooks In The Climate Change Kitchen: The Case For An Administrative Remedy For Damages Caused By Increased Greenhouse Gas Concentrations, Benjamin Reese

Michigan Journal of Environmental & Administrative Law

Recent federal and state court decisions have made clear that federal common law claims against emitters of greenhouse gases are not sustainable; however, those same courts seem to have given state common law tort claims the green light, at least if the claims are brought in the state where the polluters are located. This Note contends that such suits are not an adequate remedy for those injured by climate change because they will face nearly insurmountable barriers in state court, and because there are major policy-level drawbacks to relying on state tort law rather than a federal solution. This Note …

The Indirect Effects Of Climate Variability On The Reproductive Dynamics And Productivity Of An Avian Predator In The Arid Southwest, Corrie C. Borgman

Biology ETDs

The deserts of the Southwestern United States are experiencing rapid warming and climate models predict declining winter precipitation. The combined effects of higher air temperatures and drought are a reduction in productivity, which may importantly impact reproduction in consumers. Here, we investigate the effects of warming and drought on the reproductive timing and output in loggerhead shrikes (Lanius ludovicianus) in central New Mexico from 2007 to 2012. We found increases in air temperature of 3°C during the breeding season (March—July) and highly variable winter and annual precipitation. With increasing spring temperatures, shrikes advanced nesting phenology by 20 days over 6 …

Vegetative And Climatic Controls On Holocene Wildfire And Erosion Recorded In Alluvial Fans Of The Middle Fork Salmon River, Idaho, Kerry Riley, Jennifer Pierce, Grant A. Meyer

Geosciences Faculty Publications and Presentations

The Middle Fork Salmon River watershed spans high-elevation mixed-conifer forests to lower-elevation shrub-steppe. In recent decades, runoff from severely burned hillslopes has generated large debris flows in steep tributary drainages. These flows incised alluvial fans along the mainstem river, where charcoal-rich debris-flow and sheetflood deposits preserve a record of latest Pleistocene to Holocene fires and geomorphic response. Through deposit sedimentology and ¹⁴C dating of charcoal, we evaluate the processes and timing of fire-related sedimentation and the role of climate and vegetation change. Fire-related deposits compose ~66% of the total measured fan deposit thickness in more densely forested upper basins …

Too Wet For Frogs, Too Dry For Lizards: Role Of Changing Precipitation On Tropical Frogs And Arid Lizards, Mason J. Ryan

Biology ETDs

During the course of the Anthropocene, humans have modified the landscape and atmosphere resulting in increased global temperatures and intensification of the hydrologic cycle over the last 100 years. Amphibians and reptiles are especially vulnerable to climate change because of their ectothermic physiology and sensitivity to changes in water availability. The role of moisture or precipitation in ectotherm responses to climate change has not been well studied, but moisture plays a vital role in all aspects of the lives of lizards and frogs. It is exceedingly difficult to study the ecological effects of changing precipitation patterns due the stochastic nature …

Recent Shoreline Erosion Rates Along Black River Bay, Jamaica: Erosion And Recovery After Hurricane Ivan In 2004, Karen Louise Zelzer

Graduate Theses/Dissertations

Rising sea level is threatening coastal areas, particularly those in the Caribbean which rely heavily on tourism and marine resources to support local economies. The purpose of this study is to analyze shoreline position along the south coast of Jamaica to determine the locations and rates of coastal change. IKONOS satellite imagery sets for 2003, 2007 and 2012 were used to monitor land use and shoreline changes along Black River Bay, including Galleon Beach Fish Sanctuary, in St. Elizabeth, Jamaica. In particular, the effect of Hurricane Ivan in 2004 on shoreline changes was evaluated. Erosion rates were significantly higher during …

Proposal For A Virginia Seed Bank, Casey Schmidt

Environmental Studies Senior Seminar Projects

Climate change is causing the ranges of native species to shift northward at a pace that outstrips the ability of many plant species to migrate and adapt (Walther et al. 2002; Renwick & Rocca 2014). Although assisted migration, the process of relocating individuals or spread of seeds through human intervention, has been used successfully in some cases to preserve species, it comes saddled with potential ecological damage and legal complications arise when these ranges cross state lines. These complications threaten Virginia’s biodiversity, especially among rare plants and those plants from habitat affected most by climate change. In order to preserve …

Riparian Zone Protocol: A Necessary Addition To An Existing Program, Natalya Ares

Environmental Studies Senior Seminar Projects

As temperature trends increase on Earth and the negative effects of anthropogenically driven climate change become clearer, the diversity and health of our natural resources continue to be threatened at a growing rate. Riparian zones, or streamside zones, are one of these natural resources that under normal conditions, provides an enormous variety of ecosystem services. Not only do they provide habitat, food, and shelter for organisms in the area, but they also act as biological and physical buffers to pollution and sedimentation. Climate change threatens the health of this natural buffer. As temperatures increase, the patterns of the season change …

The Adopt-A-Wetland Program, Lindsey Hines

Environmental Studies Senior Seminar Projects

Wetlands are a “biological super system” hosting a vital reservoir of biodiversity potential. Conserving wetlands and protecting their biodiversity is instrumental in upholding the ecosystem services wetlands provide. These ecosystem services of flood control, food supply, clean water, recreational areas and more are major elements in Virginia’s economy and cultural society. Current models projecting climate change impacts on the Virginian coastline predict sea-level rise to be incompatible with rate of migration and adaptation needed for wetlands. Existing wetland conservation efforts are lacking the required action to combat these imminent problems. Land acquisition is essential to accommodate wetland migration to ensure …

Climate Change And Invasive Species: Invasive Management Teams, Virginia Fredliani

Environmental Studies Senior Seminar Projects

In Virginia, invasive species cost the state approximately $1 billion annually due to forest loss and crop damage (Pimentel et al. 2005). There are approximately 38 invasive species and suffer as a result, which affects biodiversity (Tausch 2008). Invasive species alter the balance of ecosystems, reducing biodiversity and ecosystem health (Gamfeldt et al. 2008). Climate change is another driver in the success of invasive species as they are better adapted to withstand climate changes over native species (Duke and Mooney 1999). To combat invasive species in Virginia this recommendation proposes the establishment of early detection and rapid response Invasive Management …

Metabolic Theory Explains Latitudinal Variation In Common Carp Populations And Predicts Responses To Climate Change, Michael J. Weber, Michael L. Brown, David H. Wahl, Daniel E. Shoup

Natural Resource Management Faculty Publications

Climate change is expected to alter temperature regimes experienced by fishes, which may also alter life history traits. However, predicting population-level responses to climate change has been difficult. Metabolic theory of ecology has been developed to explain how metabolism controls a variety of ecological processes, including life history attributes. Thus, this theory may be a useful tool for predicting fish population responses to climate change. To understand how climate change may alter freshwater fish life history, we measured population characteristics (e.g., recruitment, growth, body size, and mortality) of 21 North American common carp Cyprinus carpio populations spanning a latitudinal gradient …

Adaptive Law In The Anthropocene, Shalanda H. Baker

Chicago-Kent Law Review

The sky has fallen. We are now firmly rooted in a new epoch scientists have named the Anthropocene, where the activities of humans will most certainly negatively impact the trajectory of Earth and its inhabitants. What the Anthropocene fully holds is uncertain, but there are a few clues. The global ecology is shifting. The oceans are dying. The planet is getting hotter and drier, and its storms increasingly volatile.

Amidst this changing climate is evidence of a failed approach to economic development in the Global South. Globally, the poor are becoming poorer. Inequality reigns as the global economy shrinks. This …

Climate And Changing Winter Distribution Of Alcids In The Northwest Atlantic, Richard R. Veit, Lisa L. Manne

Publications and Research

Population level impacts upon seabirds from changing climate are increasingly evident, and include effects on phenology, migration, dispersal, annual survivorship, and reproduction. Most population data on seabirds derive from nesting colonies; documented climate impacts on winter ecology are scarce. We studied interannual variability in winter abundance of six species of alcids (Charadriiformes, Alcidae) from a 58-year time series of data collected in Massachusetts 1954–2011. We used counts of birds taken during fall and winter from coastal vantage points. Counts were made by amateur birders, but coverage was consistent in timing and location. We found significant association between winter abundance of …

Exploring The Effect Of Climate Change On Biological Systems, Nardos Sori

Chemistry & Biochemistry Theses & Dissertations

The present and potential future effect of global warming on the ecosystem has brought climate change to the forefront of scientific inquiry and discussion. For our investigation, we selected two organisms, one from cyanobacteria and one from a cereal plant to determine how climate change may impact these biological systems. The study involved understanding the physiological and adaptive responses at both the genetic and protein function levels to counteract environmental stresses. An increase in atmospheric carbon dioxide is a key factor in global climate change and can lead to alterations in ocean chemistry. Cyanobacteria are important, ancient and ubiquitous organisms …

Growth Of A Deep-Water, Predatory Fish Is Influenced By The Productivity Of A Boundary Current System, Hoang Minh Nguyen, Adam N. Rountrey, Jessica J. Meeuwig, Peter G. Coulson, Ming Feng, Stephen J. Newman, Anya M. Waite, Corey B. Wakefield, Mark G. Meekan

Fisheries Research Articles

The effects of climate change on predatory fishes in deep shelf areas are difficult to predict because complex processes may govern food availability and temperature at depth. We characterised the net impact of recent environmental changes on hapuku (Polyprion oxygeneios), an apex predator found in continental slope habitats (>200 m depth) by using dendrochronology techniques to develop a multi-decadal record of growth from otoliths. Fish were sampled off temperate south-western Australia, a region strongly influenced by the Leeuwin Current, a poleward-flowing, eastern boundary current. The common variance among individual growth records was relatively low (3.4%), but the …
