Bending The Carbon Curve: Fire Management For Carbon Resilience Under Climate Change, E. Louise Loudermilk, Robert M. Scheller, Peter J. Weisberg, Alec M. Kretchun

Environmental Science and Management Faculty Publications and Presentations

Context: Forest landscapes are increasingly managed for fire resilience, particularly in the western US which has recently experienced drought and widespread, high-severity wildfires. Fuel reduction treatments have been effective where fires coincide with treated areas. Fuel treatments also have the potential to reduce drought-mortality if tree density is uncharacteristically high, and to increase long-term carbon storage by reducing high-severity fire probability.

Objective: Assess whether fuel treatments reduce fire intensity and spread and increase carbon storage under climate change.

Methods: We used a simulation modeling approach that couples a landscape model of forest disturbance and succession with an ecosystem model of …

The Effect Of Salinity Acclimation On The Upper Thermal Tolerance Threshold Of The European Green Crab, Lauren S. Muñoz-Tremblay, A. L. Kelley, Catherine De Rivera

Environmental Science and Management Faculty Publications and Presentations

Fluctuations in salinity and temperature, among other varying environmental conditions, are stressors in estuaries and may work together to alter the physiological response of organisms that inhabit such environments. Laboratory assessments that investigate how animals respond to multiple environmental stressors can provide an ecological framework for understanding physiological performance across varying conditions. In this study, European green crabs, Carcinus maenas, were collected from Seadrift Lagoon, California, USA (37°54′27.82″N, 122°40′19.56″W) and were lab-acclimated at three different salinity concentrations typical of many estuaries: 15, 25, and 35 PSU at 12 °C (± 1 °C). After acclimation, crabs from each salinity treatment experienced …

Mathematics, Physics, and Computer Science Faculty Articles and Research

Air pollution contributes to a large fraction of the total mortality estimated under the global burden of disease project (GBD) of the World Health Organization (WHO). This paper discusses an integrated study to obtain the spatiotemporal characteristics of particulate matter (PM10 and PM2.5) and trace gases (O3, SO2, NO2, and CO) pollutants in Hangzhou City (China) for the years 2014–2016. Our detailed analysis shows a relationship between air pollutants and land-use/land-cover change. Air quality parameters (PM2.5 and PM10) and trace gases (SO2, NO2, and CO) show strong monthly variations in the months of January (higher values) and July (lower values). …

Fossil Fuel Asset Risk Analysis: Clark University Endowment, Travis A. Dodge, B. Maiwand Akbari

Student Works

The environmental and social risks of climate change are well known and perhaps inevitable. The economic and financial risks are less so. The many financial risks associated with climate change embedded in endowment portfolio fossil fuel holdings are leading many institutional stakeholders to enter into dialogue and take action. Divestment is emerging as an effective strategy for limiting portfolio exposure and tackling climate change itself.

Our team’s goals were to assess whether the Clark University endowment portfolio faces any of these risks and evaluate the impacts on asset values. Our findings show that the Clark endowment does face these same …

Sustainability Assessment Of U.S. Beef Production Systems, Greg Thoma, Ben Putman, Marty Matlock, Jennie Popp, Leah English

Food Systems

With increasing public concern and awareness of agricultural sustainability issues, comprehensive methodologies such as life cycle assessment are required to benchmark the beef industry and identify areas of opportunity for continuous improvement. To that end, the Beef Checkoff completed a retrospective sustainability assessment benchmark in 2013 by using Eco-efficiency analysis to compare the years 2005 and 2011. At the time of the analysis, the methodology used was the most up-to-date and comprehensive – indeed the analysis remains one of the only complete cradle-to-grave assessments of the U.S. beef industry. In 2015, a further refined version of the Eco-efficiency analysis was …

Influence Of The Interaction Of Calcium Carbonate Particles With Surfactants On The Degree Of Water Pollution In Small Rivers, Petry Spataru, Francisco Fernandez, Joseph W. Sista, Tudor Spataru, Oxana Spinu, Igor Povar

Publications and Research

Introduction: The influence of the interaction of calcium carbonate (CaCO3) and surface-active substances (SAS; surfactants) with different chain lengths and cationic and anionic hydrophilic centers has been analyzed.

Results: Laboratory simulations indicate reduced negative influences on cationic SAS nitrification/self-purification processes in the presence of anionic species. This suggests the role of complex ionic formation [anionic SAS * cationic SAS] as a cause of this effect. UV-Vis spectra of lauryl sulfate (LS) and of cetyltrimethylammonium (CTMA), as well as of their mixtures in ratios of 2:1 and 1:1, treated by fine particles of CaCO3, display decreased amounts of SAS in analyzed …

Economic Evaluation Of Coastal Land Loss In Louisiana, Stephen R. Barnes, Craig Bond, Nicholas Burger, Kate Anania, Aaron Strong, Sarah Weilant, Stephanie Virgets

Journal of Ocean and Coastal Economics

Louisiana has lost approximately 1,880 square miles of land over the past eighty years. Projections suggest that in a future without action, the next fifty years could result in the loss of 1,750 additional square miles of land area. As land loss continues, a large portion of the natural and man-made capital stocks of coastal Louisiana will be at greater risk of damage, either from land loss or from the associated increase in storm damage. We estimate the replacement cost of capital stock directly at risk from land loss ranges from approximately $2.1 billion to $3.5 billion with economic activity …

Rebuilding Silicon Valley - An Assessment Of The Silicon Valley Corporate Campus And The Potential For Suburban Sustainability, Eden Lindeman

Master's Projects and Capstones

Silicon Valley is the San Francisco Bay Area’s economic powerhouse and is herald for its innovation and success. However, Silicon Valley’s urban design is unsustainable and characterized by remote and large corporate campuses that contribute to job sprawl and heavy traffic congestion. Many of the buildings are also not performing at an efficient level and are due for deep overhauls to cut back energy consumption and costs. The inevitable effects of climate change continue to loom large over the world, heightening the importance for the built environment to be reformed into an environment that can mitigate and adapt to climate …

Embodied Carbon: A Framework For Prioritizing And Reducing Emissions In The Building Industry, Natalie C. Wheating

Master's Projects and Capstones

Global climate change is one of the most impactful environmental issues in modern times, and the construction industry is known to be one of the largest contributors to carbon emissions—one of the key causes of climate change. Embodied carbon emissions of buildings are an often overlooked, but significant, influencer of a building’s overall carbon footprint. This gives rise to the need for improved life cycle analysis of buildings and identification of opportunities to reduce the total carbon footprint of a building throughout its life cycle. This paper analyzes the current state of the building industry that limits the consideration of …

Landowner And Practitioner Perspectives On Private Land Conservation Programs, Michelle L. Lute, Caitlyn R. Gillespie, Dustin R. Martin, Joseph J. Fontaine

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

Efforts to reverse declines in native grasslands benefit from agricultural policies that encourage private land conservation. The U.S. Department of Agriculture’s Conservation Reserve Program (CRP) improved conservation across landscapes but enrollment has declined. We used sequential exploratory mixed methods to compare landowner and conservation practitioners’ perceptions, evaluate perceived benefits, and identify potential improvements to CRP. Focus groups of practitioners informed a quantitative survey of landowners who had properties >160 total acres in Nebraska. Results suggest potential misalignment in perceptions between practitioners and landowners. Practitioners were concerned that conservation, especially of wildlife, was secondary to profit. But the majority of landowners …

The Limitation Of Spread Of Non-Native Marine Invertebrates From Artificial Structures To Natural Habitats, Whitney Mcclees, Catherine E. De Rivera

ESM Colloquium

Artificial structures created for aquatic anthropogenic activities are often colonized and fouled by many non-native species, few of which have invaded natural areas. Some research has indicated predation is limiting the spread of non-native species, while other research has indicated that it is dispersal-driven. To determine the effects of dispersal limitation and predation on the risk to surrounding habitats of being invaded by non-native species established on marina docks, we used a three-factor design, deploying seven unglazed ceramic panels per each treatment combination of 1) inside versus outside a marina in Yaquina Bay, Oregon; 2) cage keeping out predators >mesh …

In this article we summarize histories of nonlinear, complex interactions among societal, legal, and ecosystem dynamics in six North American water basins, as they respond to changing climate. These case studies were chosen to explore the conditions for emergence of adaptive governance in heavily regulated and developed social-ecological systems nested within a hierarchical governmental system. We summarize resilience assessments conducted in each system to provide a synthesis and reference by the other articles in this special feature. We also present a general framework used to evaluate the interactions between society and ecosystem regimes and the governance regimes chosen to mediate …

A Spatial Relationship Between Stream Slope Stability And Water Quality Within An Urban Watershed In Rock Island, Il, Joseph Teresi

Celebration of Learning

The consistently observed phenomenon of highly altered streams and degraded water quality draining urban areas across the U.S is described as the urban stream syndrome. Rock Island, Illinois, contains a population of nearly 39,000 people, and houses industrial and logistical businesses amidst a city of aging infrastructure. Streams occupy ravines that have incised into the Quaternary loess plateau, flowing south towards the Rock River and north or west towards the Mississippi River. In an attempt to understand better the severity of Rock Island’s urban stream syndrome, this project analyzed stream slopes within the Rock Island watershed to categorize their level …
