Climate Diagnostics Of The Extreme Floods In Peru During Early 2017, Rackhun Son, Shih-Yu Simon Wang, Wan-Ling Tseng, Christian W. Barreto Schuler, Emily Becker, Jin-Ho Yoon
Climate Diagnostics Of The Extreme Floods In Peru During Early 2017, Rackhun Son, Shih-Yu Simon Wang, Wan-Ling Tseng, Christian W. Barreto Schuler, Emily Becker, Jin-Ho Yoon
Plants, Soils, and Climate Faculty Publications
From January through March 2017, a series of extreme precipitation events occurred in coastal Peru, causing severe floods with hundreds of human casualties and billions of dollars in economic losses. The extreme precipitation was a result of unusually strong recurrent patterns of atmospheric and oceanic conditions, including extremely warm coastal sea surface temperatures (SST) and weakened trade winds. These climatic features and their causal relationship with the Peruvian precipitation were examined. Diagnostic analysis and model experiments suggest that an atmospheric forcing in early 2017, which was moderately linked to the Trans-Niño Index (TNI), initiated the local SST warming along coastal …

Potential Ecological And Socio-Economic Effects Of A Novel Megaherbivore Introduction: The Hippopotamus In Colombia, Amanda L. Subalusky, Elizabeth P. Anderson, German Jimenez, David Post, David Echeverri Lopez, Sebastian Garcia-R., Laura J. Nova Leon, Juan R. Reatiga Parrish, Ana Rojas, Sergio Solari, Luz F. Jimenez-Segura
Department of Earth and Environment
Introduced species can have strong ecological, social and economic effects on their non-native environment. Introductions of megafaunal species are rare and may contribute to rewilding efforts, but they may also have pronounced socio-ecological effects because of their scale of influence. A recent introduction of the hippopotamus Hippopotamus amphibius into Colombia is a novel introduction of a megaherbivore onto a new continent, and raises questions about the future dynamics of the socio-ecological system into which it has been introduced. Here we synthesize current knowledge about the Colombian hippopotamus population, review the literature on the species to predict potential ecological and socio-economic …
Evidence For Accelerated Weathering And Sulfate Export In High Alpine Environments, John T. Crawford, Eve-Lyn S. Hinckley, M. Iggy Litaor, Janice Brahney, Jason C. Neff
Evidence For Accelerated Weathering And Sulfate Export In High Alpine Environments, John T. Crawford, Eve-Lyn S. Hinckley, M. Iggy Litaor, Janice Brahney, Jason C. Neff
Watershed Sciences Faculty Publications
High elevation alpine ecosystems—the 'water towers of the world'—provide water for human populations around the globe. Active geomorphic features such as glaciers and permafrost leave alpine ecosystems susceptible to changes in climate which could also lead to changing biogeochemistry and water quality. Here, we synthesize recent changes in high-elevation stream chemistry from multiple sites that demonstrate a consistent and widespread pattern of increasing sulfate and base cation concentrations or fluxes. This trend has occurred over the past 30 years and is consistent across multiple sites in the Rocky Mountains of the United States, western Canada, the European Alps, the Icelandic …
Estimating Carbon Flux From Optically Recording Total Particle Volume At Depths Below The Primary Pycnocline, Alexander B. Bochdansky, Robert B. Dunbar, Dennis A. Hansell, Gerhard J. Herndl
Estimating Carbon Flux From Optically Recording Total Particle Volume At Depths Below The Primary Pycnocline, Alexander B. Bochdansky, Robert B. Dunbar, Dennis A. Hansell, Gerhard J. Herndl
OES Faculty Publications
Optical instruments can rapidly determine numbers and characteristics of water column particles with high sensitivity. Here we show the usefulness of optically assessed total particle volume below the main pycnocline to estimate carbon export in two systems: the open subarctic North Atlantic and the Ross Sea, Antarctica. Both regions exhibit seasonally high phytoplankton production and efficient export (i.e., a strong biological pump). Total particle volumes in the mesopelagic (200-300 m) were significantly correlated with those in the overlying surface mixed layer (50-60 m), indicating that most particles at depth reflect export from the surface. This connectivity, however, is modulated by …
Direct And Indirect Effects Of Temperature And Prey Abundance On Bald Eagle Reproductive Dynamics, Joshua H. Schmidt, Judy Putera, Tammy L. Wilson
Direct And Indirect Effects Of Temperature And Prey Abundance On Bald Eagle Reproductive Dynamics, Joshua H. Schmidt, Judy Putera, Tammy L. Wilson
United States National Park Service: Publications
Understanding the mechanisms by which populations are regulated is critical for predicting the effects of large-scale perturbations. While discrete mortality events provide clear evidence of direct impacts, indirect pathways are more difficult to assess but may play important roles in population and ecosystem dynamics. Here, we use multi-state occupancy models to analyze a long-term dataset on nesting bald eagles in south-central Alaska with the goal of identifying both direct and indirect mechanisms influencing reproductive output in this apex predator. We found that the probabilities of both nest occupancy and success were higher in the portion of the study area where …
Green Strategic Planning Approach For International Shipping Activities, Xiaofang Wu, Luoping Zhang, Huan Feng
Green Strategic Planning Approach For International Shipping Activities, Xiaofang Wu, Luoping Zhang, Huan Feng
Department of Earth and Environmental Studies Faculty Scholarship and Creative Works
Sustainability is a long-term and ultimate goal for international shipping, although it is slowly making progress. The shipping perspective that moves away from “port-to-port” operations to “door-to-door” services also requires international shipping to take a long-term and holistic view instead of fragmented efforts. How to achieve the long-term sustainability goal becomes a key issue for door-to-door international shipping. Hence, green strategic planning for door-to-door international shipping was proposed with green development that puts forward the eco-centric point of view as its basic theory for sustainability. This study used a strategic decision-making approach, a so-called multi-dimensional decision-making (MDDM), coupled with the …
Environmental And Energy Assessment Of Biomass Residues To Biochar As Fuel: A Brief Review With Recommendations For Future Bioenergy Systems, Mengshan Lee, Yi-Li Lin, Pei-Te Chiueh, Walter Den
Environmental And Energy Assessment Of Biomass Residues To Biochar As Fuel: A Brief Review With Recommendations For Future Bioenergy Systems, Mengshan Lee, Yi-Li Lin, Pei-Te Chiueh, Walter Den
Water Resources Science and Technology Faculty Publications
This study explores the environmental and energy benefits of biomass residues, including crop residues and agricultural waste, for the production of renewable energy in the form of biochar as fuel, in order to offer recommendations for policy makers, by reviewing information regarding the key environmental issues associated with the implementation of the systems. The highest environmental benefits for biochar-to-fuel systems were most observed in reduction of global warming potentials (i.e., carbon abatement), particularly for those integrated with combined heat and power technology, or for those incorporating electricity offsets from biochar combustion and co-firing. But all of these practices come …

A Model For The Prediction Of Antimicrobial Resistance In Escherichia Coli Based On A Comparative Evaluation Of Fatty Acid Profiles, Randal S. Stahl, Bledar Bisha, Sebabrata Mahapatra, Jeffrey C. Chandler
USDA Wildlife Services: Staff Publications
Antimicrobial resistance is a threat to agricultural production and public health. In this proof-of-concept study, we investigated predicting antimicrobial sensitive/resistant (S/R) phenotypes and host sources of Escherichia coli (n = 128) based on differential fatty acid abundance. Myristic (14:0), pentadecanoic acid (15:0), palmitic (16:0), elaidic (18:19) and steric acid (18:0) were significantly different (α = 0.05) using a two-way ANOVA for predicting nalidixic acid, ciprofloxacin, aztreonam, cefatoxime, and ceftazidime S/R phenotypes. Additionally, analyses of palmitoleic (16:1), palmitic acid (16:0), methyl palmitate (i-17:0), and cis-9,10-methyleneoctadecanoic acid (19:0Δ) showed these markers were significantly different (α = 0.05) between isolates obtained from cattle …

Answering Global Warming’S Hottest Debate: A Better Way To Tax Carbon, Saleh Husseini
Op-Eds from ENSC230 Energy and the Environment: Economics and Policies
Some of you are sick of hearing about it, some of you don’t really care, and the rest of you are probably the reason the first group is sick of hearing about it, but regardless of which category you fall into, one thing is certain: climate change is real and it’s already happening. With that said, I’m moving forward under the assumption that all of us here believe in science and understand this phenomenon to be largely a result of post-industrial anthropogenic activity. In which case, reducing our emissions is the only way to prevent climate change from becoming a …

The Prairie Pothole Region of North America is characterized by millions of depressional wetlands, which provide critical habitats for globally significant populations of migratory waterfowl and other wildlife species. Due to their relatively small size and shallow depth, these wetlands are highly sensitive to climate variability and anthropogenic changes, exhibiting inter- and intra-annual inundation dynamics. Moderate-resolution satellite imagery (e.g., Landsat, Sentinel) alone cannot be used to effectively delineate these small depressional wetlands. By integrating fine spatial resolution Light Detection and Ranging (LiDAR) data and multi-temporal (2009–2017) aerial images, we developed a fully automated approach to delineate wetland inundation extent at …
Synthesis And Connection Of Iridium Hydrogen Evolution Catalyst To Chlorella Vulgaris Photosystem I For Light-Driven Hydrogen Evolution, Anna Ramirez
Honors Program Theses and Projects
Hydrogen gas has been shown to be a promising energy source as options other than fossil fuels are being looked at in the face of anthropogenic climate change. It is known that anthropogenic climate change is caused by the production of greenhouse gases being let into the atmosphere, specifically a common reason for this is the burning of fossil fuels for energy. The overall goal of this project is to design a biochemical hybrid system that will be used to make H 2 gas and does not require the use of fossil fuels. Burning hydrogen as fuel produces only water …

In light of recent recoveries of marine mammal populations worldwide and heightened concern about their impacts on marine food webs and global fisheries, it has become increasingly important to understand the potential impacts of large marine mammal predators on prey populations and their life-history traits. In coastal waters of the northeast Pacific Ocean, marine mammals have increased in abundance over the past 40 to 50 y, including fish-eating killer whales that feed primarily on Chinook salmon. Chinook salmon, a species of high cultural and economic value, have exhibited marked declines in average size and age throughout most of their North …

Wildfire is a major natural disaster affecting socioeconomics and ecology. Remote sensing data have been widely used to estimate the wildfire danger with an advantage of higher spatial resolution. Among the several wildfire related indices using remote sensing data, Temperature Vegetation Dryness Index (TVDI) assesses wildfire danger based on both Normalized Difference Vegetation Index (NDVI) and Land Surface Temperature (LST). Although TVDI has physical advantages by considering both weather and vegetation condition, previous studies have shown TVDI does not performed well compare to other wildfire related indices over the Korean Peninsula. In this study we have attempted multiple modification to …
Beavers Alter Stream Macroinvertebrate Communities In Northeastern Utah, Susan E. Washko, Brett B. Roper, Trisha Brooke Atwood
Beavers Alter Stream Macroinvertebrate Communities In Northeastern Utah, Susan E. Washko, Brett B. Roper, Trisha Brooke Atwood
Watershed Sciences Faculty Publications
- Understanding changes in macroinvertebrate communities is important because they play a large role in stream ecosystem functioning, and they are an important food resource for fish. Beaver‐induced changes to stream morphology could alter macroinvertebrate communities, which in turn could affect food webs and ecosystem function. However, studies investigating the effects of North American beaver activities on macroinvertebrates are rare in the inter‐mountain west, an area with high potential for beaver‐assisted restoration.
- The aim of this study was to quantify differences in the macroinvertebrate community between unaltered segments of streams and within beaver ponds in north‐eastern Utah, U.S.A. We assessed macroinvertebrate …

The upper Colorado River basin drains the western slope of the Rocky Mountains province of North America and hosts a rich record of fluvial terraces and volcanic deposits that provide an archive of bedrock river incision since the Late Miocene. Here we present new geochronology from fluvial deposits and associated volcanic units using multiple methods (luminescence, cosmogenic-burial, 40Ar/39Ar basalt and detrital sanidine, and U/Pb detrital zircon) to reconstruct a detailed record of bedrock incision in the upper Colorado River over timescales ranging from Miocene to Late Pleistocene. Late Miocene (ca. 11–8 Ma) basalt flows perched 800–1700 m above the Colorado …
How To Promote Education For Sustainable Development? Vision Of The Educational Situation And Its Contribution To Sustainable Development., Khalid Aada
Writing and Language Studies Faculty Publications and Presentations
During the last decade, the importance of leaving a rational paradigm, debtor of functionalist and utilitarian models, towards another more congruent with the preservation of natural resources, and therefore of life, has been widely discussed. In the same way, different voices have been raised, pointing out the urgency of inserting these precepts into the educational field, hoping to achieve the true cultural transformation that is needed to consolidate the change. Multiple International Entities promote sustainability in Education as an initiative that should be ambitious, complex and reforming character, given the global scope of the social, economic and environmental situation affecting …

Wind Is The First Step To Winning, Martin Brannaman
Op-Eds from ENSC230 Energy and the Environment: Economics and Policies
Wind energy is the way of the future, and those who don’t have it will get left behind. Wind has already proven to be useful to countries in Europe, such as Denmark, Germany, and Spain. These countries are benefited from EU policy, to help alleviate some economic stress that might come from having diversified energy sources. This diversification of energy is good for countries economically and energy wise, allows them to not be too heavily reliant upon one source. This issue is clearly on display in America who is heavily reliant on oil and coal for example, the 1973 oil …

The Wind Energy Adaptation of Nebraska
Today there are many things in the world that we rely on, heaters for warmth, cars for travel, and many other commodities that our way of living is dependent on. One of the most overlooked aspects of society is the need for power. Each and every American is dependent on power somehow, yet the vast majority of us do not think twice when flipping a switch. We all know that flipping a switch means the lights come on, when turning the ignition in our car we don’t think of the process behind the engine …

Op-Eds from ENSC230 Energy and the Environment: Economics and Policies
Is it just me or is there something about election time that makes politicians overly ambitious? The candidates for the 2020 presidential election are fighting to convince American voters they are the best choice. One of the most common tactics for accomplishing this is providing voters with an unattainable amount of promises for making our problems magically disappear. While these ambitions are “attention-grabbing” and somewhat successful in acquiring votes, so many of them go unaccomplished or un-addressed once the candidate enters the white house. No candidate, from any party, is immune to this infectious tendency that accompanies running a campaign. …

Neglecting A Wind Energy Portfolio Leaves Nebraska Behind Its Neighbors, Conner Vokoun
Op-Eds from ENSC230 Energy and the Environment: Economics and Policies
Nebraska is a state that prides itself on the productivity of our land. We dutifully don our foam corn hats at Memorial Stadium and boast that Nebraska beef is what’s for dinner. But Nebraska’s land holds an untapped resource that our neighboring states are taking advantage of: wind. Nebraska must adopt a renewable portfolio to double production of wind energy in our state over the next five years. A renewable portfolio is a regulation that sets a minimum amount of power that can be produced by renewable sources, such as solar, wind, and hydroelectric. Currently, Nebraska does not have any …
Subsidize Or Suffer, Dallas Smith
Subsidize Or Suffer, Dallas Smith
Op-Eds from ENSC230 Energy and the Environment: Economics and Policies
The standard for energy production and consumption in the US has historically been the use of coal or oil. In the earliest days of the industrial revolution, coal was king. For a society to achieve such a goal as the expansion and fortification of infrastructure, well, society as a whole, the means absolutely justify the ends. But what if the means of producing energy didn’t have to look like what they did over a hundred years ago? Well they don’t. The use of new renewable, sustainable energy could prove to be beneficial in many aspects, environmental health especially. By subsidizing …

Linfield University Wine Studies Reports
This report describes the impacts of climate and phenology on vintage for the North Willamette Valley in Oregon in 2019. A relatively mild early winter in 2018 was followed by a cold and wet second half of winter in 2019 and then a wet, but warm, spring. The growing season saw a few mild frosts during late April, but started off warmer than average, moderating through mid-vintage with fewer than average heat spikes. Near-record precipitation amounts during late June and early July brought increased disease pressure to the region. The vintage will be remembered for the early rains in September …

Adaptation To Climate Change, Pascal Ntaganda
Op-Eds from ENSC230 Energy and the Environment: Economics and Policies
Climate is changing rapidly. Some scientists say that the effects are now irreversible. The foundation on which government organizations, some of them being the congress in the United States, is not strong enough to stop climate change. The fact that the approaches being taken target market-based situations, makes it inefficient. Governments create solutions to reduce the impacts, as they make sure that these activities do not affect their economies. The level at which effects of climate change threaten life and resources of a country, is what stimulates the economy to adapt to the strategies set to mitigate climate change. In …

Making Renewables Profitable For Lincoln Electrical System, Jack Mensinger
Op-Eds from ENSC230 Energy and the Environment: Economics and Policies
The potential for Nebraska to integrate renewable energy sources, such as solar and wind, in a financially sustainable and profitable method, has been proposed and shot down. Too many Nebraskans continue to doubt and reject renewables due to the perception that they are too expensive and the continued cost over traditional energy sources are too high. Most of Nebraska’s energy comes from coal, (63%) as of 2018, with the remainder lying primarily in nuclear (15%), and wind (14%). With the innovations and adoption of renewables by other states, what is keeping Nebraskans from joining the renewable party? The primary reason …

“The world is gonna end in 12 years if we don't address climate change and your biggest issue is how are we gonna pay for it? ” This is a direct quote from Alexandria Ocasio-Cortez, a sitting U.S. congresswoman. In the next few sentences, she also proceeds to say that climate change is “our generations World War II”. 70 million people died in World War II, not only is it doing disrespect to those who gave the ultimate sacrifice, but it is physically impossible to compare war to climate change.

Don’T Give Up On Nuclear Energy, Daniel Gertner
Op-Eds from ENSC230 Energy and the Environment: Economics and Policies
The nuclear power plant failures at Three Mile Island and Chernobyl in the late 1970s and 1980s split Americans into two passionate camps. For some, nuclear plants posed serious threats to both environmental and national security, and, for others, nuclear energy remained the most viable path to clean, reliable power in the United States. But following the fervent debates of the late 20th century, the national conversation around nuclear power stagnated. A few ardent advocates and opponents notwithstanding, nuclear power left the public eye. Popular energy debates—especially among young people—now center around flashier topics like the Green New Deal, electric …
The Dirty Clean Fuel, Sawyer Krivanek
The Dirty Clean Fuel, Sawyer Krivanek
Op-Eds from ENSC230 Energy and the Environment: Economics and Policies
Hydraulic fracking began nearly 80 years ago and was initially headlined as a brand new, fuel efficient alternative to coal and oil. Natural gas has been disguised as a clean fuel, when in reality it is just another dirty, polluting, environmentally harmful fossil fuel. The detriments of fracking heavily outweigh the benefits, and it needs to be banned on public and private lands. Natural gas has been viewed as a cleaner alternative to coal and oil, so immediately fossil fuel industries took advantage of that narrative. Consumers, eager for cleaner alternatives, have been tricked into buying into the fracking fad. …
