Building Ssps For Climate Policy Analysis: A Scenario Elicitation Methodology To Map The Space Of Possible Future Challenges To Mitigation And Adaptation, Julie Rozenberg, Céline Guivarch, Robert Lempert, Stéphane Hallegatte

Fondazione Eni Enrico Mattei Working Papers

The scientific community is now developing a new set of scenarios, referred to as Shared Socio-economic Pathways (SSPs) to replace the SRES scenarios. To be used to investigate adaptation and mitigation, SSPs need to be contrasted along two axes: challenges to mitigation, and challenges to adaptation. This paper proposes a methodology to develop SSPs with a “backward” approach. The methodology is based on (i) an a priori identification of potential drivers of mitigation and adaptation challenges; (ii) a modelling exercise to transform these drivers into a large set of scenarios; (iii) an a posteriori selection of a few SSPs among …

A Water Quality Investigation Of Kimages Creek, Michael Trop

Theses and Dissertations

Analysis of continuous monitoring water quality data (temperature, specific conductivity, depth, pH, dissolved oxygen, and turbidity) at two locations in a tidal freshwater creek (Kimages Creek) characterized seasonal variation and responses to short-term events. Supplemental water quality measurements were collected to describe longitudinal variations in the creek. There were significant differences in water quality between the two continuous monitoring stations (one tidal and unforested, the other non-tidal and forested) over varying time scales. Rain events showed increases in turbidity, depth and dissolved oxygen, and reductions in temperature, conductivity, and pH at both stations. Tides influenced the water quality at the …

The Disappearing Provision: Medical Liability Reform Vanishes From The Patient Protection And Affordable Care Act Despite State Court Split, Rafael Andre Roberti

Legislation and Policy Brief

The legal and medical communities have debated the impact and necessity of medical liability reform for over twenty years. At the heart of the debate is the question of how to strike a balance between compensating patients and their families for the thousands of deaths and injuries resulting from medical errors that occur annually, and encouraging physicians to continue to care for patients across America. While several states have passed medical liability reform laws previously, on March 23, 2010, President Obama signed the Patient Protection and Affordable Care Act (ACA)—colloquially known as the “health care bill”—that contains provisions on medical …

Impact Of Salt On Denitrification Potential In Roadside Environments, Nakita A. Lancaster

Master's Theses

Urban systems are impacted by changes in hydrology and water chemistry, altering their ability to mitigate detrimental impacts to coastal water bodies, particularly those that result from high volumes of stormwater runoff. The elevated level of impervious cover increases not only runoff but also contaminant loading of nutrients, metals, and road salt used for deicing in cold weather climates. Current stormwater management strategies, while focused on managing the changes in hydrology associated with urbanization, also are designed to mitigate the pollutant loading. Here we investigate the impact that road salt will have on nitrogen removal in roadside environments. Sediments were …

Use Of Anticoagulant Rodenticides In Single-Family Neighborhoods Along An Urban-Wildland Interface In California, Monica Bartos, Sylvie Dao, Dale Douk, Stephanie Falzone, Eric Gumerlock, Stephanie Hoekstra, Kaitlin Kelly-Reif, David Mori, Chay Tang, Cassandra Vasquez, Jennifer Ward, Sarah Young, Anita T. Morzillo, Seth P. D. Riley, Travis Longcore

Cities and the Environment (CATE)

Urbanization poses many threats for many wildlife species. In addition to habitat loss and fragmentation, non-target wildlife species are vulnerable to poisoning by rodenticides, especially acutely toxic second generation anticoagulant rodenticides (SGARs). Although such poisonings are well documented for birds and mammals worldwide, the pathways by which these widely available compounds reach non-target wildlife have not been adequately studied, particularly in urban landscapes. Long-term studies of wild carnivores in and around Santa Monica Mountains National Recreation Area, a national park north of Los Angeles, have documented >85% exposure to anticoagulant rodenticides among bobcats, coyotes, and mountain lions. To investigate potential …

Creek And Lake Water Analysis Of The Little Calumet East Branch Watershed, Nicholas H. Feller, Melissa Dorton

Symposium on Research and Creative Expression (SORCE)

The overall goal of this project is to collect and analyze baseline water quality data in the Little Calumet East Branch (LCEB) watershed. This watershed spans portions of Porter and LaPorte counties in northwest Indiana and drains into Lake Michigan. The LCEB currently has impaired water quality. The Indiana Department of Environmental Management (IDEM) has awarded Save the Dunes Conservancy Foundation a two year grant to develop and implement a Watershed Management Plan to improve water quality. During the summer of 2012, the following water quality parameters were collected weekly from 15 sites spread throughout the watershed: 1) pH, 2) …

Essential Spawning Habitat For Atlantic Sturgeon In The James River, Virginia., Geoffrey Austin

Theses and Dissertations

Substrate composition plays a critical role in determining the spawning success of Atlantic sturgeon. A benthic analysis of the tidal freshwater portion of the James River, Virginia, was performed to locate and protect remaining sturgeon spawning habitat within the James River system. I modeled structural habitat, substrate distribution, and river bathymetry from Richmond, Virginia to the Appomattox River confluence. A classification model was developed to describe the dominant substrate type (mud/silt, sand, gravel, bedrock) using side scan sonar data collected from August 2011-Febuary 2012. River depth, bottom imagery, substrate density (hardness), and ground truth substrate samples were interpolated into a …

Using Stable Isotope Analysis To Study Zooplankton Trophic Ecology In San Francisco Estuary, Steven C. Westbrook, Julien Moderan, Wim Kimmerer

STAR Program Research Presentations

Zooplankton biomasses in estuaries are often high and represent an important food source for fish, like theendangered Delta Smelt. Human interferences (nitrates from crops, freshwater flow alteration, invasive species introduction…) have altered the structure of the San Francisco Estuary (SFE) ecosystem. We use stable isotope analysis to improve our knowledge of the planktonic food web in the SFE and gain insights into its evolution over the past decades. Every living thing has a specific isotopic signature. For example, in the plankton we study exists Carbon 13 and Carbon 12. Carbon 13 is different only because it has one extra neutron, …

Functional Response Of Protected Larval Stage Delta Smelt (Hypomesus Transpacificus), Jorge Ruiz, Lindsay Sullivan, Wim Kimmerer, Joan Lindberg

STAR Program Research Presentations

Delta smelt (Hypomesus transpacificus) is a protected slender-bodied fish endemic to the San Francisco Estuary. Smelt prey upon various zooplankton including the copepods such as Pseudodiaptomus forbesi. This experiment studied the prey maximum feeding rate of 2 larval stages (21 DHP, 35 DPH) of Delta smelt on various concentrations of P. forbesi. The copepod prey was offered at 7 different concentrations (2No./L–120No./L). After feeding was terminated the free prey and ingested prey were counted and analyzed to find the feeding rate of Delta smelt. Maximum feeding rate was found to be at much higher prey densities …

Developing Monitoring Methods For Leptasterias Spp. As Sentinel Species In Detecting Local Environmental Changes, Zachary Sturbaum, Kathryn Nuessly, Riley J. Smith, C. Sarah Cohen

STAR Program Research Presentations

Leptasterias spp., a six-rayed sea star, is found in rocky intertidal habitats ranging from Alaska to central California. Leptasterias spp. can be monitored on a broad scale throughout their range by a variety of means using timed counts and random plot censusing in order to detect both large-scale and local-level changes in the environment due to climate change, land-based human activity, or other environmental events. Leptasterias brood their young externally until the embryos grow into fully developed juveniles. These juveniles disperse by crawling away, limiting their dispersal potential. This localized dispersal provides an opportunity to use Leptasterias spp …

Population Density Of Carcinus Maenas In Seadrift Lagoon, Khalila Sailor, Gregory Ruiz

STAR Program Research Presentations

Seadrift Lagoon is a small private community located within the Stinson Beach community of Marin County in Central California. Its seclusion provides the perfect getaway for wealthy San Franciscans and the invasive European green crab, Carcinus maenas. It is believed that Seadrift Lagoon harbors a seedling population of Carcinus maenas capable of spreading these invader along the west coast of the United States and Canada. In 2009, collaborated efforts were made to eradicate this invasive crab from Seadrift Lagoon by the Smithsonian Environmental Research Center (SERC), Portland State University, and the University of California, Davis. This is an assessment …

Diironcarbonyl-Coumarin Complex: Preparation Intramolecular Electron Transfer And Electro-Generation Of Hydrogen, Charles A. Mebi, Joshua J. Trujillo, Anwar A. Bhuiyan

Faculty Publications - Physical & Earth Sciences

A new organometallic complex coupling photoactive coumarin to a diironhexacarbonyl unit has been successfully prepared and its composition and electronic structure confirmed by elemental and spectroscopic analyses. Emission spectral analysis of the complex reveals photoinduced intramolecular electron transfer from coumarin to the iron-carbonyl moiety. The compound is electrochemically reduced at -1.24 V vs. Fc/Fc +. This reduction is irreversible, attesting to the instability of the complex. Electrochemical evolution of hydrogen in the presence of the complex has been studied and results are discussed. © Versita Sp. z o.o.

Effects Of Meloidogyne Incognita, Soil Physical Parameters, And Thielaviopsis Basicola On Cotton Root Architecture And Plant Growth, Jianbing Ma

Graduate Theses and Dissertations

The root-knot nematode, Meloidogyne incognita, and the seedling pathogen, Thielaviopsis basicola, commonly co-exist in Arkansas cotton fields and may interact resulting in increased losses. The primary objective of this research was to evaluate the effects of soil physical parameters on these soilborne pathogens and cotton growth in controlled environmental, field, and microplot studies. Controlled environmental experiments used two soil bulk densities and four pathogen treatments: non-infested soil, soil infested with M. incognita or T. basicola and soil infested with both pathogens. The results indicated bulk density generally did not affect seedling growth or disease since soils had low penetration resistance …

Responses Of Common Diving Petrel Chicks (Pelecanoides Urinatrix) To Burrow And Colony Specific Odours In A Simple Wind Tunnel, Gregory B. Cunningham, Richard W. Van Buskirk, Mark J. Hodges, Gabrielle A. Nevitt

Biology Faculty/Staff Publications

Researchers have previously assumed that common diving petrels (Pelecanoides urinatrix) have a limited sense of smell since they have relatively small olfactory bulbs. A recent study, however, showed that adult diving petrels prefer the scent of their own burrow compared to burrows of other diving petrels, implying that personal scents contribute to the burrow’s odour signature. Because diving petrels appear to be adapted to use olfaction in social contexts, they could be a useful model for investigating how chemically mediated social recognition develops in birds. A first step is to determine whether diving petrel chicks can detect familiar and unfamiliar …

Drugs, Crime, And The Epigenetics Of Hedonic Allostasis, Anthony Walsh, Hailey Johnson, Jonathan D. Bolen

Criminal Justice Faculty Publications and Presentations

Researchers have found staggering numbers of drug addicts among incarcerated populations and have conceded that drug abuse is an important correlate of deviant behavior, but few included an understanding of the biological process leading to drug addiction. Chronic drug abuse and criminality are housed within a much broader propensity of some individuals to engage in a variety of antisocial behaviors, and this article clarifies the link and proposed shared mechanisms between criminal behavior and drug abuse through a molecular-genetic and neurobiological lens. Multiple genes, enzymes, and transcription factors are involved in drug addition, with over 100 genes known to be …

The Abundance And Distribution Of Gelatinous Zooplankton In The San Francisco Estuary, Amalia Borson, Lindsay Sullivan, Wim Kimmerer

STAR Program Research Presentations

Until recently, gelatinous zooplankton were not considered important components of the San Francisco Estuary (SFE) foodweb. However, anecdotal evidence, ongoing research, and a few published reports and papers suggest an increase in their abundance over the last 10 to 20 years. Of particular interests are three species of introduced hydromedusae (Blackfordia virginica, Maeotias marginata, and Moerisia lyonsi). All three inhabit the fresh to brackish regions of the estuary, including Suisun Bay, the channels of Suisun Marsh, and the western Sacramento-San Joaquin Delta, and are seasonally abundant throughout late summer and fall. As a result, they overlap …

Reduction In Carbon Uptake During Turn Of The Century Drought In Western North America, Christopher R. Schwalm, Christopher A. Williams, Kevin Schaefer, Dennis Baldocchi, T. Andrew Black, Allen H. Goldstein, Beverly E. Law, Walter Oechel, Kyaw Tha Paw U, Russel L. Scott

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Fossil fuel emissions aside, temperate North America is a net sink of carbon dioxide at present^1–3. Year-to-year variations in this carbon sink are linked to variations in hydroclimate that affect net ecosystem productivity^3,4. The severity and incidence of climatic extremes, including drought, have increased as a result of climate warming^5–8. Here, we examine the effect of the turn of the century drought in western North America on carbon uptake in the region, using reanalysis data, remote sensing observations and data from global monitoring networks. We show that the area-integrated strength of the western North American …

A Daily Temperature Record For Central Texas, 1896-2011, Matthew Kain Taylor

Graduate Theses and Dissertations

A continuous record of 882,693 daily maximum, minimum, and mean temperature measurements for seven weather stations in central Texas dating from August 1, 1896, to August 31, 2011, were screened and corrected for missing values and inhomogeneities. The resulting data were averaged to create a 115-year unbroken regional record of daily temperature for central Texas. This record indicates warming in daily, seasonal, and annual temperatures. Winter warm temperature extremes have increased over the period of record while warm temperature extremes during the summer months have remained largely unchanged. Summer heat wave days and the length of heat waves have increased …

Is Local Food In Your Future?: An Analysis Of The Viability Of The Local Food Movement, Jennifer A. Sliney

Pell Scholars and Senior Theses

The Local Food Movement has arisen in recent decades as a proposed solution to problems in the current food distribution system. Proponents of the movement look to solve problems such as unsustainable farming practices, greenhouse gas emissions, and unhealthy communities. Skeptics raise questions as to whether local food is truly capable of accomplishing any of those. The author proposes that as a solution, aspects of the Local Food Movement such as urban agriculture and attempts at community development should be taken more seriously in order to create a better future for the land and people alike.
