Working Trees Info: How Can Agroforestry Help Pollinators?

Working Trees (USDA-NAC)

Over one hundred crop species in North America require a visit from an insect pollinator to be most productive. In the past, native bees, feral honey bees, and other pollinators could meet the needs of these diverse crops because farms were typically interspred with pollinator habitat. Today, farms in the United States are larger and have less nearby habitat to support pollinators.

Private landowners can do a lot to support these critical pollinators by providing habitat and food sources for honey bees, native bees, butterflies, and others. Pollinator habitat and floral diversity on the farm also benefit producers of insect …

Alpha-Lipoic Acid Supplementation Protects Enzymes From Damage By Nitrosative And Oxidative Stress, Sylvia Hiller, Robert Dekroon, Eric D. Hamlett, Longquan Xu, Cristina Osorio, Jennifer Robinette, Witold Winnik, Stephen Simington, Nobuyo Maeda, Oscar Alzate, Xianwen Yi

United States Environmental Protection Agency: Publications

Background: S-nitrosylation of mitochondrial enzymes involved in energy transfer under nitrosative stress may result in ATP deficiency. We investigated whether α-lipoic acid, a powerful antioxidant, could alleviate nitrosative stress by regulating S-nitrosylation,which could result in retaining themitochondrial enzyme activity.

Methods: In this study, we have identified the S-nitrosylated forms of subunit 1 of dihydrolipoyllysine succinyltransferase (complex III), and subunit 2 of the α-ketoglutarate dehydrogenase complex by implementing a fluorescence-based differential quantitative proteomics method.

Results: We found that the activities of these two mitochondrial enzymes were partially but reversibly inhibited by S-nitrosylation in cultured endothelial cells, and that their activities …

Estimating Ozone And Secondary Pm2.5 Impacts From Hypothetical Single Source Emissions In The Central And Eastern United States, Kirk R. Baker, Robert A. Kotchenruther, Rynda C. Hudman

United States Environmental Protection Agency: Publications

Secondary pollutant impacts from emissions of single sources may need to be assessed to satisfy a variety of regulatory requirements including the Clean Air Act New Source Review and Prevention of Significant Deterioration programs and the National Environmental Policy Act. In this work, single source impacts on O₃ and secondary PM_2.5 are estimated with annual 2011 photochemical grid model simulations where new hypothetical sources are added to the central and eastern United States with varying precursor emission rates and emission release heights. Impacts from these hypothetical sources are tracked with photochemical grid model source apportionment. Single source impacts …

Seasonality Of Coliform Bacteria Detection Rates In New Jersey Domestic Wells, Thomas B. Atherholt, Nicholas A. Procopio, Sandra M. Goodrow

United States Environmental Protection Agency: Publications

It is important that indicators of fecal pollution are reliable. Coliform bacteria are a commonly used indicator of fecal pollution. As other investigators have reported elsewhere, we observed a seasonal pattern of coliform bacteria detections in domestic wells in New Jersey. Examination of a statewide database of 10 years of water quality data from 93,447 samples, from 78,207 wells, generated during real estate transactions, revealed that coliform bacteria were detected in a higher proportion of wells during warm weather months. Further examination of the seasonal pattern of other data, including well water pH, precipitation, ground and surface water temperatures, surface …

Temporal Trends In The Spatial Distribution Of Impervious Cover Relative To Stream Location, J. Wickham, A. Neale, M. Mehaffey, T. Jarnagin, D. Norton

United States Environmental Protection Agency: Publications

Use of impervious cover is transitioning from an indicator of surface water condition to one that also guides and informs watershed planning and management, including Clean Water Act (33 U.S.C. §1251 et seq.) reporting. Whether it is for understanding surface water condition or planning and management, impervious cover is most commonly expressed as summary measurement (e.g., percentage watershed in impervious cover). We use the National Land Cover Database to estimate impervious cover in the vicinity of surface waters for three time periods (2001, 2006, 2011). We also compare impervious cover in the vicinity of surface waters to watershed summary estimates …

Cyanotoxins In Inland Lakes Of The United States: Occurrence And Potential Recreational Health Risks In The Epa National Lakes Assessment 2007, Keith A. Loftin, Jennifer L. Graham, Elizabeth D. Hillborn, Sarah C. Lehmann, Michael T. Meyer, Julie E. Dietze, Christopher B. Griffith

United States Environmental Protection Agency: Publications

A large nation-wide survey of cyanotoxins (1161 lakes) in the United States (U.S.) was conducted during the EPA National Lakes Assessment 2007. Cyanotoxin data were compared with cyanobacteria abundance- and chlorophyll-based World Health Organization (WHO) thresholds and mouse toxicity data to evaluate potential recreational risks. Cylindrospermopsins, microcystins, and saxitoxins were detected (ELISA) in 4.0, 32, and 7.7% of samples with mean concentrations of 0.56, 3.0, and 0.061 mg/L, respectively (detections only). Co-occurrence of the three cyanotoxin classes was rare (0.32%) when at least one toxin was detected. Cyanobacteria were present and dominant in 98 and 76% of samples, respectively. Potential …

Carbon Storage In Us Wetlands, A. M. Nahlik, M. S. Fennessy

United States Environmental Protection Agency: Publications

Wetland soils contain some of the highest stores of soil carbon in the biosphere. However, there is little understanding of the quantity and distribution of carbon stored in our remaining wetlands or of the potential effects of human disturbance on these stocks. Here we use field data from the 2011 National Wetland Condition Assessment to provide unbiased estimates of soil carbon stocks for wetlands at regional and national scales. We find that wetlands in the conterminous United States store a total of 11.52 PgC, much of which is within soils deeper than 30 cm. Freshwater inland wetlands, in part due …

Identification Of Lead-Sensitive Expression And Splicing Quantitative Trait Loci In Drosophila Melanogaster By Analysis Of Rna-Seq Data, Wen Qu

Wayne State University Dissertations

Lead exposure has long been one of the most important topics in global public health since it is a potent developmental neurotoxin. Here, we conducted an expression QTL (eQTLs) analysis, which is genome-wide association analysis of genetic variants with differential gene expression, in the male heads of 79 Drosophila melanogaster recombinant inbred lines originally from eight parental strains in the presence or absence of developmental exposure to 250 µM lead acetate. The aim was to study the effects of lead exposure on gene expression and identify the lead-responsive genes. After detecting 1,536 cis-eQTLs and 952 trans-eQTLs (1000 permutation threshold at …

Current Status And Conservation Of Mountain Ungulates In Mongolia, Badamjav Lkhagvasuren, Yansanjav Adiya, Garam Tsogtjargal, Garam Amgalanbaatar, Rich Harris

Erforschung biologischer Ressourcen der Mongolei / Exploration into the Biological Resources of Mongolia, ISSN 0440-1298

In November 2009, we conducted a countrywide survey for wild sheep or argali and Siberian ibex. Field survey teams sampled in total 134 argali distribution units within Mongolia, which are estimated to occupy approximately 46,603 km² of the whole area of 60,237 km² that been previously mapped as populated by argali. They observed 385 groups of argali, totaling 3.373 individuals. Our point estimate of argali is 18,140 with a lower 95% confidence limit of 9,193 and an upper 95% confidence limit of 43,135.

At the same time the authors observed 162 groups of ibex, totaling 2,541 individuals and our point …

Non-Point Sources And Point Sources For Nutrient And Fecal Microbe Contamination In A Typical Upland Stream: Tates Creek, Madison County, Kentucky, Walter S. Borowski, Malcolm P. Frisbie

EKU Faculty and Staff Scholarship

Tates Creek (Madison County, Kentucky) is characterized by an oversupply of nutrients and fecal microbe contamination. Its watershed is dominated by pastureland and immature woodlands with scattered settlements served by septic systems, whereas, 5% of the watershed drains urban areas of Richmond, Kentucky. Creek waters are eutrophic and commonly display levels of Escherichia coli deemed unfit for human contact by United States Environmental Protection Agency standards. Both point and non-point sources existed for stream contaminants. A secondary sewage treatment plant (STP) discharged effluent into the creek until mid-2011 and was a point source for nitrate and phosphate. Pastureland likely contributes …

Influential Factors In Encouraging Or Dissuading Orlando Businesses To Seek Leed Certification, Katrina M. Zdanowicz

Honors Program Theses

Orlando, Florida, is home to 85 building projects that have received a Leadership in Energy and Environmental Design (LEED) certification and 74 projects that are in the process of seeking certification. Over 90 percent of these 159 buildings have been or are being rated by LEED commercial standards. This paper argues that while LEED has played a valuable role in encouraging environmentally sustainable design in the Orlando commercial sector and will continue to be a significant presence in sustainability discussions, local government legislation can assist the end-goals of LEED by promoting more localized initiatives. The benefits of LEED certification include …

A Comparison Between 2010 And 2006 Air Quality And Meteorological Conditions, And Emissions And Boundary Conditions Used In Simulations Of The Aqmeii-2 North American Domain, Till E. Stoeckenius, Christian Hogrefe, Justin Zagunis, Timonthy M. Sturtz, Benjamin Wells, Tanarit Sakulyanontvittaya

United States Environmental Protection Agency: Publications

Several participants in Phase 2 of the Air Quality Model Evaluation International Initiative (AQMEII-2) who are applying coupled models to the North American domain are comparing model results for two years, 2006 and 2010, with the goal of performing dynamic model evaluation. From a modeling perspective, the differences of interest are the large reductions in domain total emissions of NO_x (21%) and SO₂ (37%) from 2006 to 2010 and significant differences in meteorological conditions between these two years. The emission reductions occurred mostly in the eastern U.S, with some reduction in emissions from western wildfires in 2010. Differences …

Potential Aquifer Vulnerability In Regions Down-Gradient From Uranium In Situ Recovery (Isr) Sites, James A. Saunders, Bruce E. Pivetz, Nathan Voorhies, Richard T. Wilkin

United States Environmental Protection Agency: Publications

Sandstone-hosted roll-front uranium ore deposits originate when U(VI) dissolved in groundwater is reduced and precipitated as insoluble U(IV) minerals. Groundwater redox geochemistry, aqueous complexation, and solute migration are important in leaching uranium from source rocks and transporting it in low concentrations to a chemical redox interface where it is deposited in an ore zone typically containing the uranium minerals uraninite, pitchblende, and/or coffinite; various iron sulfides; native selenium; clays; and calcite. In situ recovery (ISR) of uranium ores is a process of contacting the uranium mineral deposit with leaching and oxidizing (lixiviant) fluids via injection of the lixiviant into wells …

Identification Of Putative Geographically Isolated Wetlands Of The Conterminous United States, Charles R. Lane, Ellen D'Amico

United States Environmental Protection Agency: Publications

Geographically isolated wetlands (GIWs) are wetlands completely surrounded by uplands. While common throughout the United States (U.S.), there have heretofore been no nationally available, spatially explicit estimates of GIW extent, complicating efforts to understand the myriad biogeochemical, hydrological, and habitat functions of GIWs and hampering conservation and management efforts at local, state, and national scales. We used a 10-m geospatial buffer as a proxy for hydrological or ecological connectivity of National Wetlands Inventory palustrine and lacustrine wetland systems to nationally mapped and available stream, river, and lake data. We identified over 8.3 million putative GIWs across the conterminous U.S., encompassing …

Water Consumption Estimates Of The Biodiesel Process In The Us, Qingshi Tu, Mingming Lu, Y. Jeffrey Yang, Don Scott

United States Environmental Protection Agency: Publications

As a renewable alternative to petroleum diesel, biodiesel has been widely used in the US and the world. However, its potential impact on water resources has not been much evaluated. This study investigates water consumption from the biodiesel process, which includes three stages: soybean irrigation, soybean-to-soybean oil processing, and biodiesel manufacturing, at both national and state levels. Mass-based allocation is performed and water consumption at the three stages is obtained on the basis of million gallons per year and gallon water per gallon biodiesel (gal/gal). The normalized water consumption (water intensity) of the irrigation, oil processing, and biodiesel production stages …

Quantitative Structure–Mesothelioma Potency Model Optimization For Complex Mixtures Of Elongated Particles In Rat Pleura: A Retrospective Study, Philip M. Cook, Joseph Swintek, Timothy D. Dawson, David Chapman, Mathew A. Etterson, Dale Hoff

United States Environmental Protection Agency: Publications

Cancer potencies of mineral and synthetic elongated particle mixtures, including asbestos fibers, are influenced by changes in fiber dose composition, bioavailability, and biodurability in combination with relevant cytotoxic dose-response relationships. An extensive rat intrapleural dose characterization data set with a wide variety of elongated particles physicochemical properties facilitated statistical analyses of pleural mesothelioma response data combined from several studies for evaluation of alternative dose-response models. Utilizing logistic regression of individual elongated particle dimensional variations within each test sample, four major findings emerged: (1) Mild acid leaching provides superior prediction of tumor incidence compared to samples that were not leached; (2) …

The Impact Of Endocrine-Disrupting Chemicals On Wildlife Conservation, Eda Reed

Honors Theses

Endocrine-disrupting chemicals (EDCs), such as those from plastics and pesticides, have been hypothesized to affect wildlife populations. According to the U.S. National Institute of Environmental Health Sciences, EDCs ‘are chemicals that may interfere with the body’s endocrine system and produce adverse developmental, reproductive, neurological, and immune effects in both humans and wildlife.’ A growing number of studies suggest wildlife are being exposed to EDCs, but how EDCs affect wildlife health and wildlife conservation is less well-understood. Through scientific literature analysis and a survey of wildlife conservationists and practitioners, this study aims to determine the current state of knowledge and data …

Corporate Social Responsibility/Sustainability Reporting Among The Fortune Global 250: Greenwashing Or Green Supply Chain?, John K. Lewis

Faculty and Staff - Articles & Papers

The sustainability reporting efforts of MNCs who are members of the Fortune Global 250 (FG250) was investigated. The focus was on sustainability reporting by MNCs of supply chain impacts. The reporting of FG250 MNCs was examined to determine if greenwashing was occurring or whether MNCs had committed to operating a green supply chain. A mixed methodology was used consisting of quantitative analysis of twenty-five MNC CSR/sustainability reports which were randomly selected from the FG250 listing. Qualitative analysis using content analysis was also conducted on the reports. Both methodologies concentrated on the sustainability reporting of the selected MNCs in regard to …

"The goal of this study is to support the implementation of the Total Maximum Daily Load regulation for the Spokane River and Lake Spokane area in Eastern Washington in partnership with United States Geologic Survey and the Washington State Department of Ecology. The influence of residential development along the north shore of the Lake Spokane reservoir in the Suncrest area was examined as a possible nonpoint source of nutrient contamination to shoreline groundwater and as a possible influence on algae growth in Lake Spokane. Surface water and groundwater samples from hand-driven piezometers were collected from three residential development categories. The …

Mobility Of Escherichia Coli Within Karst Terrains, Kentucky, Usa, Ashley M. Bandy

Theses and Dissertations--Earth and Environmental Sciences

Bacterial contamination of karst aquifers is a concern as water quality across the globe deteriorates in the face of decreasing water security. This study examined the transport and attenuation of two non-virulent isolates of Escherichia coli in relation to traditional groundwater tracers such as rhodamine WT dye and latex microspheres in two karst regions in Kentucky. Differential movement between the four tracers was observed in both epikarst and karst aquifer traces, with differences in behavior dependent on flow conditions. Attenuation was greater for the bacterial isolate containing the iha gene, compared to the isolate containing the kps gene. Microspheres of …

Assessment Of Her2-Neu In Breast Cancer Lines Upon Differential Exposures To Xenoestrogens, Abha Aggarwal

Walden Dissertations and Doctoral Studies

Synthetic xenoestrogens have differential estrogenic properties. Research has shown that exposures to xenoestrogens could promote breast cancer by disrupting normal function of the human epidermal growth factor receptor 2 (Her2) gene. Although animal models demonstrated a connection between xenoestrogen exposure and Her2 activity, no study using human cells has systematically examined their carcinogenic potential influencing the Her2 gene expression. Furthermore, breast cancer cells are phenotypically disparate (ER+, Her2+), with some phenotypes (Her2+), leading to more aggressive disease. This study aimed to dosimetrically assess the carcinogenic potential of commonly used xenoestrogens influencing Her2 gene expression, and delineate cellular phenotypes at greater …

Success Stories And Emerging Themes In Conservation Physiology, Christine L. Madliger, Steven J. Cooke, Erica J. Crespi, Jennifer L. Funk, Kevin R. Hultine, Kathleen E. Hunt, Jason R. Rohr, Brent J. Sinclair, Cory D. Suski, Craig K. R. Willis, Oliver P. Love

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

The potential benefits of physiology for conservation are well established and include greater specificity of management techniques, determination of cause–effect relationships, increased sensitivity of health and disturbance monitoring and greater capacity for predicting future change. While descriptions of the specific avenues in which conservation and physiology can be integrated are readily available and important to the continuing expansion of the discipline of ‘conservation physiology’, to date there has been no assessment of how the field has specifically contributed to conservation success. However, the goal of conservation physiology is to foster conservation solutions and it is therefore important to assess whether …

Assessing Public Health Burden Associated With Exposure To Ambient Black Carbon In The United States, Ying Li, Daven K. Henze, Darby Jack, Barron H. Henderson, Patrick L. Kinney

ETSU Faculty Works

Black carbon (BC) is a significant component of fine particulate matter (PM_2.5) air pollution, which has been linked to a series of adverse health effects, in particular premature mortality. Recent scientific research indicates that BC also plays an important role in climate change. Therefore, controlling black carbon emissions provides an opportunity for a double dividend. This study quantifies the national burden of mortality and morbidity attributable to exposure to ambient BC in the United States (US). We use GEOS–Chem, a global 3-D model of atmospheric composition to estimate the 2010 annual average BC levels at 0.5 x 0.667° …

Human Shields And Redistribution Of Prey Species Complicate The Utility Of Protected Areas As Ecological Baselines, Wesley Sarmento

Graduate Student Theses, Dissertations, & Professional Papers

A key goal of protected areas is the conservation of biodiversity, an aim that garners increasing public support through positive experiences. Increasing visitation, however, can come at the cost of reduced ecological integrity. A fundamental conundrum is that if parks are to serve as our most pristine places, then we must understand how our presence alters species interactions. Species redistributing closer to people is of growing management concern both in and out of national parks because of 1) human safety, 2) animal health, and 3) ecological consequences. Across parks drivers of distributional change are often dissimilar, and include movement to …
