A Dendrochronological Analysis Of Insect Outbreaks And Climate Effects On Tamarack From Indiana And Michigan, Nicholas Lorin Flinner Jan 2014

A Dendrochronological Analysis Of Insect Outbreaks And Climate Effects On Tamarack From Indiana And Michigan, Nicholas Lorin Flinner

All-Inclusive List of Electronic Theses and Dissertations

Disturbances have a strong impact on tree stand dynamics across the world. In North America, the larch sawfly (Pristiphora erichsonii) and larch casebearer (Cleophora laricella) are two non-native species of insects affecting tamarack across much of their native range. The majority of research on the effects of larch sawfly on tamarack (Larix laricina) has been conducted in Canada with very little dendrochronological work in the United States along the geographical boundary of tamarack or on the effects of larch casebearer on radial growth. As a consequence, very little is known about the relationship between tamarack and these insects' outbreaks in …

Predominant And Substoichiometric Isomers Of The Plastid Genome Coexist Within Juniperus Plants And Have Shifted Multiple Times During Cupressophyte Evolution, Wenhu Guo, Felix Grewe, Amie Cobo-Clark, Weishu Fan, Zelin Duan, Robert P. Adams, Andrea E. Schwarzbach, Jeffrey P. Mower

Health & Biomedical Sciences Faculty Publications

Most land plant plastomes contain two copies of a large inverted repeat (IR) that promote high-frequency homologous recombination to generate isomeric genomic forms. Among conifer plastomes, this canonical IR is highly reduced in Pinaceae and completely lost from cupressophytes. However, both lineages have acquired short, novel IRs, some of which also exhibit recombinational activity to generate genomic structural diversity. This diversity has been shown to exist between, and occasionally within, cupressophyte species, but it is not known whether multiple genomic forms coexist within individual plants. To examine the recombinational potential of the novel cupressophyte IRs within individuals and between species, …

Risk, Uncertainty And Precaution: Lessons From The History Of Us Environmental Law, Robert V. Percival Jan 2014

Risk, Uncertainty And Precaution: Lessons From The History Of Us Environmental Law, Robert V. Percival

Faculty Scholarship

Globalization and expanding world trade are creating new pressures to harmonize environmental standards. Countries increasingly are borrowing legal and regulatory policy innovations from one another, moving toward greater harmonization of regulatory policies. Regulatory policy generally seeks to prevent harm before it occurs, but the reality is that it usually has been more reactive than precautionary, responding only after harm has become manifest. As regulators seek to improve their responses to new and emerging environmental risks, it is useful to consider what lessons can be learned from past experience with regulatory policy. This chapter reviews controversies over regulatory policy through the …

Kids Playing For Keeps: A Feasibility Study Of Coronary Heart Disease Intervention In A Rural African American Community, Carla Allen Noah

College of Graduate Studies: Theses & Dissertations

The prevalence of Coronary heart disease (CHD) and the associated modifiable risk factors, combined with the known health disparities that exist in the African American (AA) community, increases the significance of prevention exponentially. Theories involving genetic and environmental factors and their interaction are gaining popularity as relevant influences on both modifiable and fixed risk factors for CHD. Innovative and targeted strategies of health promotion and preventative measures are needed to combat the growing trend of modifiable risk factors for heart disease within the southern rural AA population. The aim of this pilot study was to evaluate the feasibility and effectiveness …

Turkish Journal of Zoology

To elucidate the genetic divergences of several Asian frog taxa, the mitochondrial 16S rRNA gene (16S) sequences of 81 populations across 6 Asian countries were analyzed. In total, 109 haplotypes were found, and the concept of a 3% difference in 16S sequence corresponding to species threshold was applied to define candidate amphibian species, for which corroborating evidence, such as morphology, ecological characteristics, and/or nuclear gene data, is required. Polypedates leucomystax, Hylarana chalconota, and Hylarana sp. from Chantaburi, Maelippet Siberut, and Langkawi Island, respectively, correspond to 3 candidate species and H. erythraea from Malaysia/Thailand represents a possible candidate species. Hylarana cf. …


Humic Substances Interfere With Detection Of Pathogenic Prion Protein, Christen B. Smith, Clarissa J. Booth, Tyler J. Wadzinski, Giuseppe Legname, Rick Chappell, Christopher J. Johnson, Joel A. Pedersen Jan 2014

Humic Substances Interfere With Detection Of Pathogenic Prion Protein, Christen B. Smith, Clarissa J. Booth, Tyler J. Wadzinski, Giuseppe Legname, Rick Chappell, Christopher J. Johnson, Joel A. Pedersen

United States Geological Survey: Staff Publications

Studies examining the persistence of prions (the etiological agent of transmissible spongiform encephalopathies) in soil require accurate quantification of pathogenic prion protein (PrPTSE) extracted from or in the presence of soil particles. Here, we demonstrate that natural organic matter (NOM) in soil impacts PrPTSE detection by immunoblotting. Methods commonly used to extract PrPTSE from soils release substantial amounts of NOM, and NOM inhibited PrPTSE immunoblot signal. The degree of immunoblot interference increased with increasing NOM concentration and decreasing NOM polarity. Humic substances affected immunoblot detection of prion protein from both deer and hamsters. We also …

United States Department of Agriculture, Forest Service / University of Nebraska-Lincoln: Faculty Publications

Climate warming is projected to affect forest water yields but the effects are expected to vary. We investigated how forest type and age affect water yield resilience to climate warming. To answer this question, we examined the variability in historical water yields at long-term experimental catchments across Canada and the United States over 5-year cool and warm periods. Using the theoretical framework of the Budyko curve, we calculated the effects of climate warming on the annual partitioning of precipitation (P) into evapotranspiration (ET) and water yield. Deviation (d) was defined as a catchment’s change in actual ET divided by P …


Anthropogenics: Human Influence On Global And Genetic Homogenization Of Parasite Populations, Dante S. Zarlenga, Eric P. Hoberg, Benjamin Rosenthal, Simonetti Mattiucci, Giuseppe Nascetti Jan 2014

Anthropogenics: Human Influence On Global And Genetic Homogenization Of Parasite Populations, Dante S. Zarlenga, Eric P. Hoberg, Benjamin Rosenthal, Simonetti Mattiucci, Giuseppe Nascetti

Harold W. Manter Laboratory of Parasitology: Faculty Publications

The distribution, abundance, and diversity of life on Earth have been greatly shaped by human activities. This includes the geographic expansion of parasites; however, measuring the extent to which humans have influenced the dissemination and population structure of parasites has been challenging. In-depth comparisons among parasite populations extending to landscape-level processes affecting disease emergence have remained elusive. New research methods have enhanced our capacity to discern human impact, where the tools of population genetics and molecular epidemiology have begun to shed light on our historical and ongoing influence. Only since the 1990s have parasitologists coupled morphological diagnosis, long considered the …


A Depth Refugium From Catastrophic Coral Bleaching Prevents Regional Extinction, Tyler B. Smith, Peter W. Glynn, Juan L. Maté, Lauren T. Toth, Joanna Gyory Jan 2014

A Depth Refugium From Catastrophic Coral Bleaching Prevents Regional Extinction, Tyler B. Smith, Peter W. Glynn, Juan L. Maté, Lauren T. Toth, Joanna Gyory

Ocean Engineering and Marine Sciences Faculty Publications

Species intolerant of changing climate might avoid extinction within refugia buffered from extreme conditions. Refugia have been observed in the fossil record but are not well documented or understood on ecological time scales. Using a 37-year record from the eastern Pacific across the two most severe El Nin˜ o events on record (1982–1983 and 1997– 1998) we show how an exceptionally thermally sensitive reef-building hydrocoral, Millepora intricata, twice survived catastrophic bleaching in a deeper-water refuge (.11 m depth). During both events, M. intricata was extirpated across its range in shallow water, but showed recovery within several years, while two other …


Mitigating The Adverse Impacts Of Hydraulic Fracturing: A Role For Local Zoning?, John R. Nolon, Jessica A. Bacher Jan 2014

Mitigating The Adverse Impacts Of Hydraulic Fracturing: A Role For Local Zoning?, John R. Nolon, Jessica A. Bacher

Elisabeth Haub School of Law Faculty Publications

This article focuses on the action localities have taken toward mitigating some of the adverse impacts of hydraulic fracturing, or hydrofracking. The Article will explore impacts at the local level and will show the governance gap that has resulted from federal and state regulations that leave many local impacts unmitigated. Zoning laws and other practices that local governments are adopting are also discussed, explaining why state preemption over the traditional role of local governments in regulating this particular heavy industrial activity is not the ideal situation.

Reverse Environmental Assessment Analysis For The Adaptation Of Projects, Plans, And Programs To The Effects Of Climate Change In The Eu Evaluation Of The Proposal For An Eia Directive, Teresa Parejo-Navajas

Sabin Center for Climate Change Law

It is clear that mitigation measures are not enough to tackle climate change effects and, therefore, some adaptation measures will be needed to improve resiliency. The new Reverse Environmental Impact Assessment (REIA) analysis, so named by Professor Michael B. Gerrard1, evaluates the impacts that the “transformed environment” – a result of the adverse effects of climate change – may cause to a project, plan, or program, in order to allow those undertaking these activities to act proactively.

There are many countries that have taken action accordingly. The EU has elaborated “Guidances” on integrating climate and biodiversity into either the Environmental …

Geochemical And Rock-Magnetic Analyses Of Kasten Cores And Surface Grab Samples From The Joinville-D'Urville Trough, Northeastern Antarctic Peninsula : Results And Correlation With The Western Antarctic Peninsula, Rachel B. Darley Jan 2014

Geochemical And Rock-Magnetic Analyses Of Kasten Cores And Surface Grab Samples From The Joinville-D'Urville Trough, Northeastern Antarctic Peninsula : Results And Correlation With The Western Antarctic Peninsula, Rachel B. Darley

Theses, Dissertations and Culminating Projects

Two sediment cores were recovered from the Joinville-d’Urville Trough on the Northeastern Antarctic Peninsula (AP) during United States Antarctic Program cruise LMG04-04. KC3 was recovered from a sediment drift off Joinville Island. KC16 was recovered from a small basin west of the drift. Both cores show a two-part magnetic susceptibility profile: the upper section shows regularly spaced highs and lows, followed by a large amplitude drop. The susceptibility profiles of these two cores are similar to those found on the western side of the AP. The purpose of this study is to determine whether the same processes drive magnetic susceptibility …

Theses, Dissertations and Culminating Projects

Drought is one of the most severe natural hazards in the world. This research aims at assessing the limited water resources for better crop-water irrigation and conservation of a drought affected agricultural area in California.

Evapotranspiration (ET) is one of the most important parameter to study crop water use for irrigation scheduling and water management. The remote sensing based ET estimation using Surface Energy Balance Algorithm for Land (SEBAL) is the efficient way to understand crop water use. Crop Water Stress Index (CWSI) quantifies plant stress under different field conditions. The remote sensing approach allows efficient irrigation by applying water …


Green Remediation Of Veterinary Antibiotics In Soil-Water Systems, Pravin Anraj Punamiya Jan 2014

Green Remediation Of Veterinary Antibiotics In Soil-Water Systems, Pravin Anraj Punamiya

Theses, Dissertations and Culminating Projects

Veterinary antibiotics (VAs) are considered emerging contaminants of concern. Considerable efforts have been made to understand the fate and transport of VAs in soil and water environment and very few have attempted to develop novel remediation strategies to overcome the problem of antibiotic resistance and potential toxicity to aquatic species. To our knowledge, the present study is a pioneer study in which it attempts to develop a low-cost, “green” remediation technique utilizing a waste byproduct of the drinking water treatment industry, namely, the Al-based water treatment residuals (Al-WTR), as a sorbent to stabilize tetracycline (TTC) and oxytetracycline (OTC) in aqueous …


The Impact Of Clapper V. Amnesty International Usa On The Doctrine Of Fear-Based Standing, Amanda M. Mcdowell Jan 2014

The Impact Of Clapper V. Amnesty International Usa On The Doctrine Of Fear-Based Standing, Amanda M. Mcdowell

Georgia Law Review

The Supreme Court's 2013 decision in Clapper v. Amnesty International USA dealt with the government's electronic surveillance authority under the Foreign Intelligence SurveillanceAct (FISA) Amendments. In a 5- 4 opinion, the Court held that a variety of U.S. persons, including attorneys and media organizations, did not have standing to challenge the constitutionality of the FISA Amendments because the plaintiffs' fear of future unlawful surveillance was not "certainly impending." Depending on how lower courts choose to interpret Clapper, the decision could have a significant impact on the doctrine of fear-based standing, which allows plaintiffs to establish standing based on fear of …


Securing Food And Livelihoods: Opportunities And Constraints To Sustainably Enhancing Household Food Production In Santa Familia Village, Belize, Siobhan B. Lozada Jan 2014

Securing Food And Livelihoods: Opportunities And Constraints To Sustainably Enhancing Household Food Production In Santa Familia Village, Belize, Siobhan B. Lozada

Graduate Student Theses, Dissertations, & Professional Papers

Rural households play an active role in reorganizing their livelihood strategies to respond to external stresses and shocks. What is unclear is the extent to which rural households can remain resilient in the face of continued external stresses and how policy actions at larger scales can more effectively encourage rural food and livelihood sustainability. Economic and ecological stresses and shocks have negatively impacted livelihood security and wider economic stability in Belize. This has increased the number of people below the poverty line to 41.3 percent, who remain disproportionately located in rural areas. With a high degree of import dependency, global …


"It Was My Job To Keep My Children Safe": Sandra Steingraber And The Parental Rhetoric Of Precaution, Mollie Katherine Murphy Jan 2014

"It Was My Job To Keep My Children Safe": Sandra Steingraber And The Parental Rhetoric Of Precaution, Mollie Katherine Murphy

Graduate Student Theses, Dissertations, & Professional Papers

Advancing the environmental movement requires overcoming a number of rhetorical challenges. Rhetors must negotiate the significant dichotomies of environmental rhetoric including human/nature, public/private, and science/experience. Moreover, they face the challenge of educating and mobilizing uninformed citizens to take action. This analysis focuses on how Sandra Steingraber, an ecologist, writer, and environmental activist, negotiates these challenges. I argue that Steingraber negotiates these challenges by turning to three interrelated rhetorical strategies: the feminine style, autobiography, and synecdoche. I illustrate this through an analysis of two texts Steingraber wrote after becoming a mother: Having Faith: An Ecologist’s Journey to Motherhood, and Raising Elijah: …


Yerba Mate (Ilex Paraguariensis) Production, Agricultural Change, And Livelihood Security In Southeastern Paraguay, Mason Robert Bradbury Jan 2014

Yerba Mate (Ilex Paraguariensis) Production, Agricultural Change, And Livelihood Security In Southeastern Paraguay, Mason Robert Bradbury

Graduate Student Theses, Dissertations, & Professional Papers

Smallholders in Southeastern Paraguay are threatened by the advance of mechanized farming, environmental degradation, and limited access to credit and inputs. Agroforestry initiatives have been proposed as a way to increase smallholder livelihood security in the face of such vulnerability. Yerba mate (Ilex paraguariensis) is a tree crop native to Paraguay that may be grown in agroforestry systems. While prices paid to farmers for yerba mate have increased in recent years, spurring interest and adoption of yerba mate production among some farmers, to this date, there have been no analyses of the effects that yerba mate production may have on …
