Assessing Population-Level Effects Of Zinc Exposure To Brown Trout (Salmo Trutta) In The Arkansas River At Leadville, Colorado, John Toll, Kristina Garber, David Deforest, William Brattin

United States Environmental Protection Agency: Publications

We assessed population-level risk to upper Arkansas River brown trout (Salmo trutta L.) due to juvenile exposure to Zn. During spring, individuals in the sensitive young-of-the-year life stage are exposed to elevated Zn concentrations from acid mine drainage. We built and used a simple life-history population model for the risk assessment, with survival and fecundity parameter values drawn from published data on brown trout populations located in the United States and Europe. From experimental data, we derived a toxicity model to predict mortality in brown trout fry after chronic exposure to Zn. We tested sensitivity of risk estimates to …

Clean Water In Haiti, Hannah Mchugh

2012 Awards for Excellence in Student Research & Creative Activity - Documents

In the past few years, Haiti has been a topic that has been in the news here in the United States for many reasons. These reports typically show the faces of hundreds of starving and injured Haitians who live in turmoil and they discuss the disasters that have befallen the country. While these reports do not usually show the more pleasant aspects, they are relatively accurate in showing the state of the majority of the country. A major impact on a country that is in such a dire state is the presence and availability of clean water. But to understand …

A Conceptual Model To Facilitate Amphibian Conservation In The Northern Great Plains, David M. Mushet, Ned H. Euliss Jr., Craig A. Stockwell

Great Plains Research: A Journal of Natural and Social Sciences

As pressures on agricultural landscapes to meet worldwide resource needs increase, amphibian populations face numerous threats including habitat destruction, chemical contaminants, disease outbreaks, wetland sedimentation, and synergistic effects of these perturbations. To facilitate conservation planning, we developed a conceptual model depicting elements critical for amphibian conservation in the northern Great Plains. First, we linked upland, wetland, and landscape features to specific ecological attributes. Ecological attributes included adult survival; reproduction and survival to metamorphosis; and successful dispersal and recolonization. Second, we linked ecosystem drivers, ecosystem stressors, and ecological effects of the region to each ecological attribute. Lastly, we summarized information on …

Estimation Of Phosphorus Bioavailability In The Water Column Of The Bronx River, New York, Jingyu Wang, Hari K. Pant

Publications and Research

Phosphorus (P) is a primary limiting nutrient in rivers and streams, and excessive P results in eutrophication of freshwater systems, in turn, excessive algal growth/toxic algal blooms, oxygen depletion, and water quality degradation. This study analyzed P pool, and hydrolysis of organic P (OP) by native phosphatases (NPase) in the water samples collected in the Bronx River. The soluble reactive P (SRP) of most of the sites’ water collected in 2006 and 2007 were higher (average 67 µg·L–1 and 68 µg·L–1, respectively) than the US Environmental Protection Agency’s (EPA) standard of 15 µg·L–1. The SRP% (SRP/TP%) average was 27% in …

Geomorphological Approach To Toxic Trace Metal Distribution Across A Medial Bar Deposit In The Trout Brook Of The Park River Watershed, Hartford, Ct, Kelsey Semrod

Senior Theses and Projects

The Trout Brook, a major tributary of the Park River watershed, was sampled for heavy metals in sediment with a focus on Pb, Cu, Cd, and Zn. These metals are known to be contaminating the river due to a history of discharge from metal finishing industries. In a watershed-wide survey conducted in September 2011, high concentrations of metals were found in the Trout Brook, with some sites exceeding the probable effect concentration (PEC). The Trout Brook contains a Sanitary Sewer Overflow (SSO) and a vegetated medial bar that may be trapping sediment. Based on the results of the earlier studies, …

Coarse Woody Debris In A Tropical Rainforest In North Queensland, Australia: Relationships With Stand Structure And Disturbance, Nadine Rea

Independent Study Project (ISP) Collection

Coarse woody debris (CWD) refers to the woody material on the forest floor, including fallen stems, large branches, coarse roots, wood pieces, and standing dead trees (snags) (Harmon et al. 1986). CWD is an essential but often overlooked aspect of ecosystems. It plays many key ecosystem roles and is instrumental in overall ecosystem functionality. While a piece of CWD decomposes, it provides key habitat for many different species, minimizes soil erosion, affects soil development, stores nutrients and water, and influences the global carbon cycle (Harmon and Hua 1991). In some forests, CWD can exist on the forest floor for hundreds …

The Vacb Model In Hòa An Village And Xeo Trâm Hamlet: Comparison And Analysis Through A Gendered Lens, Alyssa Bosold

Independent Study Project (ISP) Collection

Burning fuel-wood, a method of traditional cooking practiced by half of all homes in Vietnam (Global Alliance for Clean Cook-stoves 2012) and the majority of homes in Hòa An Village and Xeo Trâm Hamlet, has significant negative consequences in terms of environmental and personal health. In Hòa An Village and Xeo Trâm Hamlet, as is true in much of Vietnam, gender roles dictate that women should be primarily responsible for household chores like cooking (World Bank 2001, Nguyen 2012, Nguyen 2012, Vo 2012). This means that women must often deal directly with the environmental dangers and safety hazards of woodstoves. …

Comparative Analysis Of Two Biological Warfare Air Samplers Using Live Surrogate Agents, James C. Enderby

Theses and Dissertations

The United States Air Force has several high-volume biological air samplers, including the XMX/2L-MIL and the Biocapture 650. Limited information is available on either in terms of its collection of viruses and bacteria. However, previous research on the XMX/2L-MIL has determined that modifications to the secondary flow rate and the use of a virus preserving collection media may provide improved virus collection rates. In this thesis, these modifications were investigated to determine their impact on the collection of viral and bacterial aerosols. Additionally, relative collection rates were compared against those for the Biocapture 650. MS2 bacteriophage was the viral surrogate …

Tates Creek is a significant tributary to the Kentucky River that has shown high levels of microbial and nutrient pollution in the past (Kentucky River Watershed Watch). We sampled the waters of Tates Creek more comprehensively by collecting stream water at 25 stations along its 13-mile length from its headwaters to the Kentucky River. Most samples were collected at the confluence of major tributaries to also access the water quality of tributary streams. Samples were collected four times between May and August 2011 during dry periods as well as immediately after a rainfall event. We measured ammonium (NH₄^{+ …}

West Of Eden: Resource Wars And Nature-Cultures In The American West, Scout Calvert

UNL Libraries: Faculty Publications

The richness and variety of the western landscape is what is at stake in hot political contests for the resources of the West: much of this public land is available to economic activity, including for mining, grazing, logging, and recreation. These uses threaten to outpace the land’s ability to renew these resources along with others, like air and water. Now in the first decade of the millennium with a new environmental awareness emerging partly from media coverage of global warming and peak oil, The American West at Risk offers a wide-ranging look at the degradation of the environment in the …

Global Monthly Water Scarcity: Blue Water Footprints Versus Blue Water Availability, Arjen Y. Hoekstra, Mesfin Mekonnen, Ashok K. Chapagain, Ruth E. Mathews, Brian D. Richter

Daugherty Water for Food Global Institute: Faculty Publications

Freshwater scarcity is a growing concern, placing considerable importance on the accuracy of indicators used to characterize and map water scarcity worldwide. We improve upon past efforts by using estimates of blue water footprints (consumptive use of ground- and surface water flows) rather than water withdrawals, accounting for the flows needed to sustain critical ecological functions and by considering monthly rather than annual values. We analyzed 405 river basins for the period 1996–2005. In 201 basins with 2.67 billion inhabitants there was severe water scarcity during at least one month of the year. The ecological and economic consequences of increasing …

The Water Footprint Of Humanity, Arjen Y. Hoekstra, Mesfin Mekonnen

Daugherty Water for Food Global Institute: Faculty Publications

This study quantifies and maps the water footprint (WF) of humanity at a high spatial resolution. It reports on consumptive use of rainwater (green WF) and ground and surface water (blue WF) and volumes of water polluted (gray WF). Water footprints are estimated per nation from both a production and consumption perspective. International virtual water flows are estimated based on trade in agricultural and industrial commodities. The global annual average WF in the period 1996–2005 was 9,087 Gm3 ∕y (74% green, 11% blue, 15% gray). Agricultural production contributes 92%. About one-fifth of the global WF relates to production for export. …

Bacterial Source Tracking Of E. Coli In A Constructed Wetland, Rose M. Martin

Master's Theses

Bacterial source tracking was used to identify sources of fecal contamination in a constructed wetland. Nucleotide sequence differences in the Escherichia coli malate dehydrogenase (mdh) gene were used to distinguish between strains isolated from pigeon and cattle feces. Fourteen E. coli isolates were taken from cattle and pigeon fecal samples and sixteen E. coli isolates were taken from wetland water samples. A region of the E. coli mdh gene was amplified via PCR and sequenced. Twelve distinct sequences were obtained. Water samples indicated the presence of both pigeon and cattle fecal contamination in the wetland. Six sequences distinct …

Brief 4: Lessons From The Multilateral Trading System For Reforming The Architecture Of The International Environmental Regime, Thomas Cottier, Manfred Elsig, Judith Wehrli

Governance and Sustainability Issue Brief Series

Recent studies on environmental regimes suggest that important lessons and policy recommendations may be drawn from the functioning of the multilateral trading regime. This brief compares the needs and goals of the trade and environment regimes, and discusses how insights from over sixty years of experience of the multilateral trading system might provide ideas for redesigning the architecture of the international environmental regime. It further calls for a better dialogue and improved complementarities between the two fields in order to enhance coherence within international law.
