Epidemic Growth Rates And Host Movement Patterns Shape Management Performance For Pathogen Spillover At The Wildlife–Livestock Interface, Kezia R. Manlove, Laura M. Sampson, Benny Borremans, E. Frances Cassirer, Ryan S. Miller, Kim M. Pepin, Thomas E. Besser, Paul C. Cross

USDA Wildlife Services: Staff Publications

Managing pathogen spillover at the wildlife–livestock interface is a key step towards improving global animal health, food security and wildlife conservation. However, predicting the effectiveness of management actions across host–pathogen systems with different life histories is an on-going challenge since data on intervention effectiveness are expensive to collect and results are system-specific.We developed a simulation model to explore how the efficacies of different management strategies vary according to host movement patterns and epidemic growth rates. The model suggested that fast-growing, fast-moving epidemics like avian influenza were best-managed with actions like biosecurity or containment, which limited and localized overall spillover risk. …

Blacklegged Tick (Ixodes Scapularis) Distribution In Maine, Usa, As Related To Climate Change, White-Tailed Deer, And The Landscape, Susan P. Elias

Electronic Theses and Dissertations

Lyme disease is caused by the bacterial spirochete Borrelia burgdorferi, which is transmitted through the bite of an infected blacklegged (deer) tick (Ixodes scapularis). Geographic invasion of I. scapularis in North America has been attributed to causes including 20th century reforestation and suburbanization, burgeoning populations of the white-tailed deer (Odocoileus virginianus) which is the primary reproductive host of I. scapularis, tick-associated non-native plant invasions, and climate change. Maine, USA, is a high Lyme disease incidence state, with a history of increasing I. scapularis abundance and northward range expansion. This thesis addresses the question: “To …

A Fishy Problem: Effects Of Atlantic Salmon Farming In The Pacific Ocean, Madeleine A. Griffith

Student Theses 2015-Present

In this report, I explore the historical, climatological, economic, and ethical issues created by the contemporary industrial salmon farming practices off Pacific coast of the United States and Canada. Chapter 1 utilizes a variety of sources from Stephen Hume’s A Stain upon the Sea to Miller’s Living in the Environment, to examine the integral part salmon plays in both freshwater and marine ecosystems, the ecosystem services salmon contribute in wild and farmed settings, and the trends in salmon consumption around the world. Chapter 2 examines the historically relevant role salmon held among indigenous societies and how that role has changed …

Effects Of Forest Management On Densities And Nest Survival Of Breeding Birds In Upland Hardwood Ecosystems, Michael Barnes

Electronic Theses & Dissertations

Over the past 50 years, significant declines in 47% of Neotropical migrant bird species have been documented in North America. Declines are most likely due to the loss and fragmentation of breeding, wintering, and stopover habitat mainly caused by agriculture and urban development. This loss of critical habitat results in population sinks that need to be maintained by immigration from a population source found in continuously forested landscapes. However, in landscapes harvested for timber, forest management practices alter the landscape and as a result, affect breeding bird abundances and nest success. The objective of our study was to determine the …

Rock ptarmigan (Lagopus muta) and willow ptarmigan (L. lagopus) are Arctic birds with a circumpolar distribution but there is limited knowledge about their status and trends across their circumpolar distribution. Here, we compiled information from 90 ptarmigan study sites from 7 Arctic countries, where almost half of the sites are still monitored. Rock ptarmigan showed an overall negative trend on Iceland and Greenland, while Svalbard and Newfoundland had positive trends, and no significant trends in Alaska. For willow ptarmigan, there was a negative trend in mid-Sweden and eastern Russia, while northern Fennoscandia, North America and Newfoundland had no significant trends. …

Policy Insights From Comparing Carbon Pricing Modeling Scenarios, Alexander R. Barron, Marc A.C. Hafstead, Adele C. Morris

Environmental Science and Policy: Faculty Publications

Carbon pricing is an important policy tool for reducing greenhouse gas pollution. The Stanford Energy Modeling Forum exercise 32 convened eleven modeling teams to project emissions, energy, and economic outcomes of an illustrative range of economy-wide carbon price policies. The study compared a coordinated reference scenario involving no new policies with policy scenarios that impose a price on all fossil fuel-related carbon dioxide (CO2) emissions in the U.S. The CO2 price scenarios begin in 2020 at $25/ton or $50/ton and rise each year over inflation at one percent or five percent. The scenarios also vary by the use of the …

Are Firm Emissions Data Likely To Be Accurate Under Carbon-Dioxide Cap & Trade Programs? An Economic Analysis, Kyle Beck

Senior Honors Projects, 2010-2019

Numerous policy makers around the world have implemented carbon dioxide (CO2) cap and trade programs in an effort to combat global climate change. However, under this policy option emitters face incentives to both overstate prior emission levels and then exaggerate emissions reductions induced by regulation. I first build a simple conceptual model which demonstrates these incentives for fraud, and then outline institutional conditions which could plausibly enhance, or else reduce, firm incentives to disseminate erroneous emissions data under this policy option. Next I analyze real world evidence suggesting that duplicitous emissions data, particularly for the pre-regulatory period, is a serious …

The inverse relationship between body size and environmental temperature is a widespread ecogeographic pattern. However, the underlying forces that produce this pattern are unclear in many taxa. Expectations are particularly unclear for migratory species, as individuals may escape environmental extremes and reorient themselves along the environmental gradient. In addition, some aspects of body size are largely fixed while others are environmentally flexible and may vary seasonally. Here, we used a long-term dataset that tracked multiple populations of the migratory piping plover Charadrius melodus across their breeding and non-breeding ranges to investigate ecogeographic patterns of phenotypically flexible (body mass) and fixed …

Many communities, including South Florida, are already having the security of their daily lives impacted as climate change causes SLR and other environmental impacts to worsen. This study reviews the Miami-Dade Sea Level Rise Task Force Report to determine how this coastal county government views SLR as a threat. Using mixed content analysis to analyze the report qualitatively and quantitatively, the Task Force's recommendations are categorized based on their focus on security, infrastructure, economics, and the environment. One finds the concerns of the people to …

Population Dynamics Of The Freshwater Mussel Lampsilis Cardium Reintroduced In Nebraska, Lindsay M. Ohlman

School of Natural Resources: Dissertations, Theses, and Student Research

The global decline of native freshwater mussels has accelerated conservation projects that preserve and restore populations, but the complex life histories among species challenges biologists in determining the most effective management strategies. This study details the conservation of plain pocketbook, a Tier I threatened mussel species in Nebraska that was artificially propagated and reintroduced into 13 sites from autumn 2016 to summer 2017. The objectives of this study were: 1) determine how handling influences mussels, and 2) evaluate mussel growth and survival following introductions.

We conducted a laboratory experiment with age-2 plain pocketbook to assess the effects of handling on …

The Niobrara National Scenic River: Exploring Co-Management Through A Case Study Of The Niobrara Council, Melissa M. Mosier

School of Natural Resources: Dissertations, Theses, and Student Research

In recent decades, government staff and local citizens have increasingly employed cooperative schemes of natural resource management, in lieu of more conventional, top-down approaches of addressing user conflicts as they relate to water resources. The focus of this project was on the Niobrara Council, a partnership of local, state, and federal representatives charged with cooperatively managing the reach of the Niobrara River that was federally designated under the Wild and Scenic Rivers Act in 1991. The project's purpose was to explore the cooperative framework of the Council, using the methodology outlined by Carlsson and Berkes (2005). This methodology involved investigating …

Soil Capability Assessment For Expanding Irrigated Agriculture In The Irwin Focus Area And Surrounding Lands, Edward (Ted) Arnold Griffin, Angela Stuart-Street, Peter Tille

Resource management technical reports

The Midlands groundwater and land assessment is a $4.7 million Water for Food project using Royalties for Regions funding. It is seeking to confirm groundwater availability in focus areas that may form precincts of 2000–3000ha suitable for intensive irrigated horticulture. Irwin is one of these.

The Department of Water identified the Irwin focus area for investigation for irrigated agriculture potential. It covers almost 7000ha to the east of Dongara in the Mid West region of Western Australia.

This report provides the land assessment for the Irwin area. We expanded the investigation to include land outside of the focus area because …

Implementing The North American Bat Monitoring Program In Nebraska: An Assessment Of Nebraska Bats With An Emphasis On Citizen Science, Baxter Seguin

School of Natural Resources: Dissertations, Theses, and Student Research

Over the past decade bat species in North America have been under immense stress due to anthropogenic activities throughout the continent along with severe declines from foreign invaders. Though many specific anthropogenic related activities such as deforestation, land-use alteration, and hibernacula disturbance/modification were the primary culprits of negative impacts on bat species in the past, they pale in comparison to the threats bats face today. White nose syndrome a disease caused by the fungus Pseudogymnoascus destructans and wind energy development have caused declines and disruptions to the bat populations of North America at an unprecedented rate.

Due to the significant …

Discontinuity Analysis Reveals Alternative Community Regimes During Phytoplankton Succession, David G. Angeler, Craig R. Allen, Dirac L. Twidwell Jr., Monika Winder

School of Natural Resources: Faculty Publications

It is well-recognized in plankton ecology that phytoplankton development can lead to distinct peaks (i.e., blooms) during spring and summer. We used a 5-year (2007–2011) phytoplankton data set and utilized discontinuity analysis to assess resilience attributes of spring and summer blooms based on the cross-scale resilience model. Using the size structure (i.e., cross-scale structure as an indicator of resilience) in the sampled plankton data, we assessed whether spring and summer blooms differ substantially between but not within blooms; that is, whether they comprise alternative community regimes. Our exploratory study supported this expectation and more broadly resilience theory, which posits that …

OHSU-PSU School of Public Health Faculty Publications and Presentations

Millions of people in the arid regions of Kenya and Ethiopia face water scarcity and frequent drought. Water resource forecasting and reliable operation of groundwater distribution systems may improve drought resilience. In this study, we examined three remote sensing data sets against in-situ sensor-collected groundwater extraction data from 221 water points serving over 1.34 million people across northern Kenya and Afar, Ethiopia between January 1, 2017 and August 31, 2018. In models containing rainfall as a binary variable, we observed an overall 23% increase in borehole runtime following weeks with no rainfall compared to weeks preceded by some rainfall. Further, …

Climate Change Governance And The Politics Of Scale: Evaluating Local Climate Protection Policies And Practices In The United States And Germany, Ayure-Inga Mark Anthony Agana

Graduate Theses and Dissertations

When it became evident that the issue of climate change needed to be acted upon, it was projected as a global scale problem. To make this rhetoric concrete, the international relations logic that ‘regimes’ of cooperating nation-states are the most feasible approach to solving problems that are global in nature was adopted. While the national level has performed poorly in climate change mitigation action, as exemplified by the United States’ refusal to ratify the Kyoto Protocol, Canada’s subsequent withdrawal from the Kyoto Protocol in 2011 after initial ratification and, more recently, the United States withdrawal from the Paris Accord, a …
