Reframing Communication About Zika And Mosquitoes To Increase Disease Prevention Behavior, Amanda E. Sorensen, Rebecca C. Jordan, Shannon Ladeau Jan 2017

Reframing Communication About Zika And Mosquitoes To Increase Disease Prevention Behavior, Amanda E. Sorensen, Rebecca C. Jordan, Shannon Ladeau

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

Emergence of invasive vector species and the diseases they carry present a clear danger to the public as well as a challenge for scientists and experts to control effectively. Given the urgent need to address this phenomenon, we suggest that desired public action toward these invasive vectors can be motivated through intentional framing in science communication. In this paper, we sought to evaluate the effect of framing about ZIKV (Zika virus) on reported willingness to comply with mosquito prevention action. Post framing intervention, we found a significant increase (N = 26, p < 0.001) in individuals willing to take preventative action against mosquitoes. By methodically investigating best communication practices, this study and others can help practitioners mobilize communities to address large-scale ecological problems. Additionally, the principles outlined here may be transferrable to other communication efforts about ecological issues outside of ZIKV and mosquitoes.


Nebraska Public Water Supply Program Summary Report 2017 Jan 2017

Nebraska Public Water Supply Program Summary Report 2017

Nebraska Department of Environmental Quality: Reports

The United States Environmental Protection Agency (EPA) established the Public Water System Supervision (PWSS) Program under the authority of the 1974 Safe Drinking Water Act (SDWA). Under the SDWA and the 1986 Amendments, EPA sets national limits on contaminant levels in drinking water to ensure that the water is safe for human consumption. These limits are known as Maximum Contaminant Levels (MCLs) and Maximum Residual Disinfectant Levels (MRDLs). For some regulations, EPA establishes treatment techniques in lieu of an MCL to control unacceptable levels of contaminants in water.

The 2001 Nebraska Legislature passed LB329 (Neb. Rev. Stat. §46-1304) which, in part, directed the Nebraska Department of Environmental Quality (NDEQ) to report on groundwater quality monitoring in Nebraska. Reports have been issued annually since December 2001. The text of the statute applicable to this report follows: “The Department of Environmental Quality shall prepare a report outlining the extent of ground water quality monitoring conducted by natural resources districts during the preceding calendar year. The department shall analyze the data collected for the purpose of determining whether or not ground water quality is degrading or improving and shall present the …


Compensatory Response Of Fathead Minnow Larvae Following A Pulsed In-Situ Exposure To A Seasonal Agricultural Runoff Event, Jonathan M. Ali, John Sangster, Daniel D. Snow, Shannon L. Bartelt-Hunt, Alan S. Kolok Jan 2017

Compensatory Response Of Fathead Minnow Larvae Following A Pulsed In-Situ Exposure To A Seasonal Agricultural Runoff Event, Jonathan M. Ali, John Sangster, Daniel D. Snow, Shannon L. Bartelt-Hunt, Alan S. Kolok

Nebraska Water Center: Faculty Publications

Agriculturally-dominated waterways such as those found throughout the Midwestern United States often experience seasonal pulses of agrichemical contaminants which pose a potential hazard to aquatic organisms at varying life stages. The objective of this study was to characterize the developmental plasticity of fathead minnow larvae in a natural environment subject to a seasonal episodic perturbation in the form of a complex mixture of agricultural stressors. Fathead minnow larvae were maintained at the Elkhorn River Research Station for a 28-d in situ exposure to an agrichemical pulse event.Minnow larvae were sampled after 14 and 28 days to characterize developmental plasticity through …


Assessing Responses Of Betula Papyrifera (Paper Birch) To Climate Variability In A Remnant Population Along The Niobrara River In Nebraska Through Dendroecological And Remote Sensing Techniques, Evan Bumann Jan 2017

Assessing Responses Of Betula Papyrifera (Paper Birch) To Climate Variability In A Remnant Population Along The Niobrara River In Nebraska Through Dendroecological And Remote Sensing Techniques, Evan Bumann

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

Remnant populations of the boreal species Betula papyrifera, found along north-facing canyons and river banks of the Niobrara River Valley in north-central Nebraska, represent one of the southernmost distributions of the species in North America. Although, the species has persisted in the Great Plains after the Wisconsin Glaciation due to the local topography and microclimatic conditions, canopy dieback has been reported in recent years, which is believed to be attributed to temperature change. Therefore, the goals of this research are to: 1) use dendroecological techniques, or the study of tree rings to assess the responses B. papyrifera to intra- and …


Effects Of Post Eviction Resettlement On Land-Use And Cover Change In Uganda’S Oil Exploration Areas, Joseph Ssekandi, John Mburu, Oliver Wasonga, Laban Macopiyo, Charles A. Francis Jan 2017

Effects Of Post Eviction Resettlement On Land-Use And Cover Change In Uganda’S Oil Exploration Areas, Joseph Ssekandi, John Mburu, Oliver Wasonga, Laban Macopiyo, Charles A. Francis

Department of Agronomy and Horticulture: Faculty Publications

Evaluation of the changes in land use and land cover change (LULCC) in respect to oil exploration across the Albertine region in Uganda has been focused around the exploration areas and protected areas, with no attention to the potential impacts of evictees’ activities on resettled areas. This study used LANDSAT images to analyze the land use and land cover changes (LULCC) among the period before eviction (2002 and 2005) at the climax of eviction and resettlements (2005-2011), and during the post-resettlement period (2011-2015) to quantify the impacts of resettlements on the environment. LANDSAT images were processed using ERDAS IMAGINE software …


Changes In Arctic Climate And Central U.S. Weather Patterns Is There A Link?, Donald A. Wilhite, Kimberly C. Morrow, Martha Shulski Jan 2017

Changes In Arctic Climate And Central U.S. Weather Patterns Is There A Link?, Donald A. Wilhite, Kimberly C. Morrow, Martha Shulski

National Drought Mitigation Center: Faculty Publications

Earlier snowmelt, decreasing soil moisture, decreased corn yields, increasing extreme precipitation events—these are some of the weather effects currently observed in the central United States that might well have their origin in the rapidly warming Arctic. These and other implications of Arctic warming were among the topics discussed at a fall 2015 workshop, Implications of a Changing Arctic on Water Resources and Agriculture in the Central U.S (Wilhite and Morrow 2016).

The United States assumed chairmanship of the Arctic Council in April 2015, making the workshop topic timely. Given the importance of the Midwest and Great Plains region as a …


Evaluation Of Satellite-Based Rainfall Estimates And Application To Monitor Meteorological Drought For The Upper Blue Nile Basin, Ethiopia, Yared Bayissa, Tsegaye Tadesse, Getachew B. Demisse, Andualem Shiferaw Jan 2017

Evaluation Of Satellite-Based Rainfall Estimates And Application To Monitor Meteorological Drought For The Upper Blue Nile Basin, Ethiopia, Yared Bayissa, Tsegaye Tadesse, Getachew B. Demisse, Andualem Shiferaw

National Drought Mitigation Center: Faculty Publications

Drought is a recurring phenomenon in Ethiopia that significantly impacts the socioeconomic sector and various components of the environment. The overarching goal of this study is to assess the spatial and temporal patterns of meteorological drought using a satellite-derived rainfall product for the Upper Blue Nile Basin (UBN). The satellite rainfall product used in this study was selected through evaluation of five high-resolution products (Climate Hazards Group InfraRed Precipitation with Stations (CHIRPS) v2.0, Precipitation Estimation from Remotely Sensed Information using Artificial Neural Networks (PERSIANN), African Rainfall Climatology and Time-series (TARCAT) v2.0, Tropical Rainfall Measuring Mission (TRMM) and Africa Rainfall Estimate …


Spatially Biased Dispersal Of Acorns By A Scatter-Hoarding Corvid May Accelerate Passive Restoration Of Oak Habitat On California’S Largest Island, Mario B. Pesendorfer, T. Scott Sillett, Scott A. Morrison Jan 2017

Spatially Biased Dispersal Of Acorns By A Scatter-Hoarding Corvid May Accelerate Passive Restoration Of Oak Habitat On California’S Largest Island, Mario B. Pesendorfer, T. Scott Sillett, Scott A. Morrison

School of Biological Sciences: Faculty Publications

Scatter hoarding by corvids (crows, jays, magpies, and nutcrackers) provides seed dispersal for many large-seeded plants, including oaks and pines. When hoarding seeds, corvids often choose nonrandom locations throughout the landscape, resulting in differential survival of seeds. In the context of habitat restoration, such disproportional storing of seeds in areas suitable for germination and establishment can accelerate expansion and recovery of large-seeded tree populations and their associated ecosystems. Here, we investigate the spatial preferences of island scrub jays Aphelocoma insularis during scatter hoarding of acorns (Quercus spp.) on Santa Cruz Island. We use a large behavioral data set on …


Coupling Ecological And Social Network Models To Assess “Transmission” And “Contagion” Of An Aquatic Invasive Species, Danielle Haak, Brian D. Fath, Valery E. Forbes, Dustin R. Martin, Kevin L. Pope Jan 2017

Coupling Ecological And Social Network Models To Assess “Transmission” And “Contagion” Of An Aquatic Invasive Species, Danielle Haak, Brian D. Fath, Valery E. Forbes, Dustin R. Martin, Kevin L. Pope

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

Network analysis is used to address diverse ecological, social, economic, and epidemiological questions, but few efforts have been made to combine these field-specific analyses into interdisciplinary approaches that effectively address how complex systems are interdependent and connected to one another. Identifying and understanding these cross-boundary connections improves natural resource management and promotes proactive, rather than reactive, decisions. This research had two main objectives; first, adapt the framework and approach of infectious disease network modeling so that it may be applied to the socio-ecological problem of spreading aquatic invasive species, and second, use this new coupled model to simulate the spread …

Stop Fighting It Nebraska: Clean Energy Is Here To Stay, Nicholas Underwood Dec 2016

Stop Fighting It Nebraska: Clean Energy Is Here To Stay, Nicholas Underwood

Op-Eds from ENSC230 Energy and the Environment: Economics and Policies

The state of Nebraska and more specifically the Nebraska Public Power District has so far shown a surprising reluctance to incorporate clean or renewable sources of power into its portfolio. The state’s reluctance is exemplified in their support for legal challenges to the Clean Power Plan put forth by the Obama Administration. NPPD in particular has decided to stick with coal as its primary fuel source and has even discouraged the construction of natural gas facilities in the state. The power utilities in this state need to develop a modern, clean energy system to avoid being left behind.

The Clean Power Plan And How It Will Change History, Abbie Andersen Dec 2016

The Clean Power Plan And How It Will Change History, Abbie Andersen

Op-Eds from ENSC230 Energy and the Environment: Economics and Policies

In a country where 30% of the population still believes that man made climate change is a myth, president Obama has made a daring effort to help fix the damage our country has already inflicted on our planet. By creating The Clean Power Plan (CPP) we’ve taken a step in the right direction as a country. The action that we take to limit our emissions within the next 10 years will likely determine the course of the rest of our existence.

In our current situation humanity has no choice other than to act, and act quickly. We have passed the …


Fossil Fuel Subsides Will Keep The Us In The Stone Age, Alexander Stejskal Dec 2016

Fossil Fuel Subsides Will Keep The Us In The Stone Age, Alexander Stejskal

Op-Eds from ENSC230 Energy and the Environment: Economics and Policies

Renewable sources will be the future of energy production for the United States. Clean sources of energy like wind and solar have been the topic of conversation for quite some time, and now they’re starting to show their ability to compete economically with fossil fuels.

Even as renewable sources of energy begin to show their gusto, they are still a part of a relatively new industry and new industries always need a little help getting off the ground. There are some forms of aid being provided for renewable sources of energy, like the production tax credit or PTCs, where the …


Solar, Why Not?, Emily Hergenrader Dec 2016

Solar, Why Not?, Emily Hergenrader

Op-Eds from ENSC230 Energy and the Environment: Economics and Policies

Imagine yourself standing outside for an hour wearing a black shirt on a 90-degree day. Now touch your shirt. Notice how warm it is? This warming is due to the sun’s energy. According to Daniel Nocera, a member of the Division of Chemistry at the Massachusetts Institute of Technology, that same heat from one hour of sun exposure is more energy than all of the energy consumed by humans in an entire year.

Energy is one of the hottest topics debated in our world today. Human existence on Earth depends on energy usage and the availability of its consumption. Due …

Why We Should Keep Worrying About The Atomic Bomb, Eric Davis

Op-Eds from ENSC230 Energy and the Environment: Economics and Policies

“… the members of the Bulletin of the Atomic Scientists Science and Security Board have looked closely at the world situation and found it highly threatening to humanity—so threatening that the hands of the Doomsday Clock must once again be set at three minutes to midnight, two minutes closer to catastrophe than in 2014…Meanwhile, as they slow the pace of disarmament, the nuclear weapon states have given other strong indications that they are committed to retaining nuclear weapons for the indefinite future” - Bulletin of the Atomic Scientists (2015).

Independent Energy, Ian Hall Dec 2016

Independent Energy, Ian Hall

Op-Eds from ENSC230 Energy and the Environment: Economics and Policies

In the world of energy, an elite selection of the world’s most influential leaders dictates the development of the world. The correlation between petroleum production and global influence is hard to ignore. The world needs energy to move and those with the energy control the movement. Saudi Arabia, Russia, and the US combine to contribute over a third of world oil production. OPEC countries however, dominate the vast energy markets around the world. Well inundated with regional conflict and hostile relations, OPEC countries remain volatile and on top of global energy production.

The energy industry has become extremely productive, fueling …


A Dynamic Power Grid For A Dynamic Age Introducing Les To A Pricing Mechanism That Assesses Demand, And Changes Every Hour, Marvin Christopher Cunningham Dec 2016

A Dynamic Power Grid For A Dynamic Age Introducing Les To A Pricing Mechanism That Assesses Demand, And Changes Every Hour, Marvin Christopher Cunningham

Op-Eds from ENSC230 Energy and the Environment: Economics and Policies

Lets say you knew someone who would buy a whole pizza when they were a little bit hungry, left their sink running when they weren’t using it, maxed out their A/C in their house when they were on vacation, and always kept their stove on just in case they wanted to cook something.

You would probably see this as horribly wasteful, and a terrible drain of money. But every time we pay our power bill, our prices assume we share these wasteful habits. The rate that we pay per kilowatt hour assumes customers are eating the whole pizza, even though …


Les To Increase Fixed Price, Nathan Blazek Dec 2016

Les To Increase Fixed Price, Nathan Blazek

Op-Eds from ENSC230 Energy and the Environment: Economics and Policies

Lincoln Electric System (LES) plans to increase the fixed amount customers pay each month and decrease the rate it charges for each kWh used.

This shift is claimed to be revenue neutral for LES. But for customers, it means they’ll save less money by turning off lights and buying more efficient appliances.

This policy is a sly and deliberate stab at ongoing conservation efforts. The decreased kilowatt pricing will give customers the perception that it is relatively unnecessary to decrease electricity usage if they are already paying a high price to initially have it. This new policy will even further …


Is Nebraska Really “The Good Life”?, Sarah Porath Dec 2016

Is Nebraska Really “The Good Life”?, Sarah Porath

Op-Eds from ENSC230 Energy and the Environment: Economics and Policies

For anyone who has ever lived in Nebraska, you know the state is filled with people who resist change. Nebraska is “The Good Life.” Any adjustments or modifications that could disrupt the lifestyle are not welcomed. The people who are elected into office clearly reflect this type of mindset.

It is time for Nebraska to get outside of their comfort zone. We need to move from the good life to the great, healthy, and progressive life by developing a state-wide Energy Efficiency Resource Standard or Goal.

20 states have Mandated Statewide Energy Efficiency Resource Standards and 8 states have Goals …


Fracking Chill, Nick Nardone Dec 2016

Fracking Chill, Nick Nardone

Op-Eds from ENSC230 Energy and the Environment: Economics and Policies

Hydraulic Fracturing or commonly known as fracking has caused a big boom in the oil and gas industry making it easier for us to extract oil and gas from the ground, but has serious side effects that as they cause harm to us and our environment. We should slow or stop fracking at once if we want a clean and healthy environment to live in.

Fracking has become widely popular in the last decade and has brought us benefits on the oil and gas side and with little lack of information and support it has been difficult to put restrictions …


The Great Plains: America’S Carbon Vault, William Davidson Dec 2016

The Great Plains: America’S Carbon Vault, William Davidson

Op-Eds from ENSC230 Energy and the Environment: Economics and Policies

As a nation we are starting a race against climate change, a competitor who has had a very long head start and only plans on picking up the pace. The Clean Power Plan has laid a blueprint to lower carbon emissions from fossil fuel burning power plants nationwide, a crucial step in recovering from decades of pollution. Meeting these goals will take years and greenhouse gasses will continue to accumulate throughout the process. Efforts beyond the scope of this plan must also be made in order to prevent emissions from sources not specifically addressed, namely sources of carbon that cannot …


Calculating The Methan-Matics Of Our Future, Victoria Salinas Dec 2016

Calculating The Methan-Matics Of Our Future, Victoria Salinas

Op-Eds from ENSC230 Energy and the Environment: Economics and Policies

In the first two decades after its release, methane, a green house gas, is 84 times more potent than carbon dioxide. Historically, atmospheric concentrations of methane remained fairly stable at around 750 ppb, significantly less than today’s levels of 1,800 ppb. Unfortunately, agricultural activity accounts for about one-fifth of total global greenhouse gas emissions, while the current production of ruminants contributes nearly 80% of these emissions due to their large populations, body size and appetites, and the anaerobic microbial fermentation that occurs during digestion. Because of methane’s severe impact on the climate, methane emissions, specifically due to the production of …


Willingness To Pay Today For A Cleaner Tomorrow, Yukihira Naoe Dec 2016

Willingness To Pay Today For A Cleaner Tomorrow, Yukihira Naoe

Op-Eds from ENSC230 Energy and the Environment: Economics and Policies

To a ten year old boy on a tedious trip across the country side, few views are more fascinating than a wind farm. Massive turbines spin slowly as if to emphasize their preposterous size and magnificence. In an era where increasing global attention is brought to climate change, renewable energy is carving its way into the minds of billions. This once free roadside attraction is now something that in the near future, we must pay and patronize, and this is where my literature begins, how willing are we to pay for renewable energy? Are you willing to pay to give …

Diversity And Impacts Of Mining On The Non-Volant Small Mammal Communities Of Two Vegetation Types In The Brazilian Amazon, Natália Carneiro Ardente, Átilla Colombo Ferreguetti, Donald Gettinger, Pricila Leal, Ana Cristina Mendes-Oliveira, Fernanda Martins-Hatano, Helena Godoy Bergallo

Harold W. Manter Laboratory of Parasitology: Faculty Publications

The CarajaÂs National Forest contains some of the largest iron ore deposits in the world. The majority of the minerals are found below a plant community known as Savana Metalo fila, or ªCangaº, which represents only 3% of the landscape within the CarajaÂs National Forest (CNF). The aim of our study was to understand the diversity of community of non-volant small mammals in the two predominant vegetation types: Ombrophilous Forest and Canga, and to examine how mining impacts these communities. Sampling was conducted from January 2010 to August 2011 in 11 sampling sites divided by the total area of Canga …
