The Effect Of Azo Textile Dyes On Gross Primary Production And Community Respiration In An Artificial Environment, Theresa L. Petzoldt Jan 2014

The Effect Of Azo Textile Dyes On Gross Primary Production And Community Respiration In An Artificial Environment, Theresa L. Petzoldt

Honors Theses

Azo dyes are the largest category of textile dyes in production today, with over 100,000 tons of dye produced yearly in the United States. Ten to fifty percent of this dye is not fixed to the fabric during the textile production process, and is therefore discarded as effluent. Because dye waste is difficult to process in wastewater treatment facilities, it is important to understand how this waste affects aquatic systems using a whole ecosystem approach. This study used an artificial stream to model the effects of four azo dyes on benthic biofilm production and respiration. Dyes were found to have …


Plant Community Composition And Structure Monitoring For Agate Fossil Beds National Monument, 2013 Annual Report, Isabel W. Ashton, Michael Prowatzke Jan 2014

Plant Community Composition And Structure Monitoring For Agate Fossil Beds National Monument, 2013 Annual Report, Isabel W. Ashton, Michael Prowatzke

United States National Park Service: Publications

Introduction

During the last century, much of the prairie within the Northern Great Plains has been plowed for cropland, planted with non-natives to maximize livestock production, or otherwise developed, making it one of the most threatened ecosystems in the United States. Within Nebraska, greater than 77% of the area of native mixed-grass prairie has been lost since European settlement (Samson and Knopf 1994). The National Park Service (NPS) plays an important role in preserving and restoring some of the last pieces of intact prairies within its boundaries. The stewardship goal of the NPS is to “preserve ecological integrity and cultural …


Quantitative Assessments Of Municipal Waste Management Systems: Using Different Indicators To Compare And Rank Programs In New York State, Krista L. Greene, David J. Tonjes Jan 2014

Quantitative Assessments Of Municipal Waste Management Systems: Using Different Indicators To Compare And Rank Programs In New York State, Krista L. Greene, David J. Tonjes

Technology & Society Faculty Publications

The primary objective of waste management technologies and policies in theUnited Statesis to reduce the harmful environmental impacts of waste, particularly those relating to energy consumption and climate change. Performance indicators are frequently used to evaluate the environmental quality of municipal waste systems, as well as to compare and rank programs relative to each other in terms of environmental performance. However, there currently is no consensus on the best indicator for performing these environmental evaluations. The purpose of this study is to examine the common performance indicators used to assess the environmental benefits of municipal waste systems to determine if …


A Review Of The Hyporheic Zone, Stream Restoration, And Means To Enhance Denitrification, Leanne Merill, David J. Tonjes Jan 2014

A Review Of The Hyporheic Zone, Stream Restoration, And Means To Enhance Denitrification, Leanne Merill, David J. Tonjes

Technology & Society Faculty Publications

The hyporheic zone is the subsurface area below and adjacent to a stream where groundwater mixes with stream water, through vertical, lateral, and longitudinal flows. The hyporheic zone connects the stream to uplands and other terrestrial environments. It is a zone of distinct faunal communities, high biological diversity and ecological complexity, and is the site of chemical processing and transformations of ground- and stream waters. The hyporheic zone is important to the overall ecosystem ecology of the stream, and it can influence stream water chemistry. Flows, reactions, and biota in the hyporheic zone are heterogeneous and patchy, making it difficult …


Changing The Climate Narrative: How A Long-Term Climate Change Might Save Our Lives, Natalie P. Harreld Jan 2014

Changing The Climate Narrative: How A Long-Term Climate Change Might Save Our Lives, Natalie P. Harreld

CMC Senior Theses

The goal of this paper is to offer new insights into the climate change debate by shifting away from the heated anthropologic arguments that dominate politics, media, and popular science. Instead, I choose to rely on the long-term impacts of a changing climate on our planet. The paper begins with a break down of key processes involved in short-term and long-term climate change, using the latest research. After a foundational understanding of climate sciences is established, we will discuss the failure of the climate change debate in educating the general public about the facts of a changing climate. Finally, the …


Closing The Knowing-Doing Gap In Invasive Plant Management: Accessibility And Interdisciplinarity Of Scientific Research, Virginia Matzek, Justin Covino, Jennifer L. Funk, Martin Saunders Jan 2014

Closing The Knowing-Doing Gap In Invasive Plant Management: Accessibility And Interdisciplinarity Of Scientific Research, Virginia Matzek, Justin Covino, Jennifer L. Funk, Martin Saunders

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Like many conservation disciplines, invasion biology may suffer from a knowing-doing gap, where scientific research fails to inform management actions. We surveyed California resource managers to evaluate engagement with scientific research and to identify research priorities. We examined managers' access to information, judgment of the usefulness of existing research, ability to generate scientific information, and priorities for future research. We found that practitioners rely on their own experience, and largely do not read the peer-reviewed literature, which they regard as only moderately useful. Less than half of managers who do research carry out experiments conforming to the norms of hypothesis …


Community Forests : A Study Of New Hampshire's Town-Owned Forests, Anna Christie-Carnicella Jan 2014

Community Forests : A Study Of New Hampshire's Town-Owned Forests, Anna Christie-Carnicella

Legacy Theses & Dissertations (2009 - 2024)

New England states have a long history of forest management, beginning in the seventeenth century, with community forests evolving over time from communal forests during colonial times to town-owned forests managed by conservation commissions in the present time. New Hampshire towns provided a case study of the current state of town-owned forest protection and management, with a focus on timber management. I administered a survey to 50 randomly sampled towns and received data from 29 about permanent protection and management activities on town-owned forestland (≥ 50 acres). I used this data, demographic, and landscape data, to evaluate permanent protection and …

Defending The Environment: A Mission For The World's Militaries, Mark P. Nevitt Jan 2014

Defending The Environment: A Mission For The World's Militaries, Mark P. Nevitt

Faculty Articles

Critics often fault the U.S. military for its environmental stewardship, and legal scholarship frequently highlights efforts by the military· to seek national security exemptions from various environmental laws and the military's poor cleanup record Yet the Department of Defense ("DoD '') is largely subject to and complies with the fall array of American environmental laws in the same manner and extent as any agency of the federal government. While the military 's environmental record is far from perfect, a comparative legal survey shows that the U.S. is at the relative forefront of effectively balancing environmental stewardship with national security.

Improving The Representation Of Roots In Terrestrial Models, Erica A.H. Smithwick, Melissa S. Lucash, M. Luke Mccormack, Gajan Sivandran Jan 2014

Improving The Representation Of Roots In Terrestrial Models, Erica A.H. Smithwick, Melissa S. Lucash, M. Luke Mccormack, Gajan Sivandran

Environmental Science and Management Faculty Publications and Presentations

Root biomass, root production and lifespan, and root-mycorrhizal interactions govern soil carbon fluxes and resource uptake and are critical components of terrestrial models. However, limitations in data and confusions over terminology, together with a strong dependence on a small set of conceptual frameworks, have limited the exploration of root function in terrestrial models. We review the key root processes of interest to both field ecologists and modelers including root classification, production, turnover, biomass, resource uptake, and depth distribution to ask (1) what are contemporary approaches for modeling roots in terrestrial models? and (2) can these approaches be improved via recent …


The Effects Of Mountaintop Removal Mining And Valley Fills On Stream Salamander Communities, Brenee' Lynn Muncy Jan 2014

The Effects Of Mountaintop Removal Mining And Valley Fills On Stream Salamander Communities, Brenee' Lynn Muncy

Theses and Dissertations--Forestry and Natural Resources

Mountaintop removal mining and valley filling (MTR/VF) is a common form of land conversion in Central Appalachia and threatens the integrity of stream ecosystems. We investigated the effects of MTR/VF on stream salamander occupancy probabilities and community structure by conducting area constrained active searches for stream salamanders within intermittent streams located in mature forest (i.e., control) and those impacted by MTR/VF. During March to June of 2013, we detected five stream salamander species (Desmognathus fuscus, D. monticol, Eurycea cirrigera, Pseudotriton ruber, and Gyrinophilus porphyriticus) and found that the probability of occupancy was greatly reduced in MTR/VF streams compared …

Conflict Translates Environmental And Social Risk Into Business Costs, Daniel M. Franks, Rachel Davis, Anthony J. Bebbington, Saleem H. Ali, Deanna Kemp, Martin Scurrah Jan 2014

Conflict Translates Environmental And Social Risk Into Business Costs, Daniel M. Franks, Rachel Davis, Anthony J. Bebbington, Saleem H. Ali, Deanna Kemp, Martin Scurrah

Geography

Sustainability science has grown as a field of inquiry, but has said little about the role of large-scale private sector actors in socio-ecological systems change. However, the shaping of global trends and transitions depends greatly on the private sector and its development impact. Market-based and command-and-control policy instruments have, along with corporate citizenship, been the predominant means for bringing sustainable development priorities into private sector decision-making. This research identifies conflict as a further means through which environmental and social risks are translated into business costs and decision making. Through in-depth interviews with finance, legal, and sustainability professionals in the extractive …

Water Conservation, Consuelo Bokum

Water Matters!

New Mexico always has had periods of water shortages, some far more long lasting and devastating than others. As warming temperature and changing weather patterns continue to develop, the likelihood that water shortages—like those felt throughout the state from 2010 through 2013—will occur with greater frequency. These changes can and have caused significant economic and environmental damage, and the risk of more harm will not improve unless we improve our water management significant.


Drought, Adrian Oglesby Jan 2014

Drought, Adrian Oglesby

Water Matters!

New Mexico is renowned for its high deserts, mild climate, and abundant sunshine. Incidentally, these physical attributes, which make New Mexico so unique and beautiful, are also characteristic of a naturally dry environment. The state has been subjected to severe drought conditions in the past, alternating with times of uncharacteristically high supplies of moisture upon which its population has at times over-relied.

This article will provide various definitions of drought and a short history of drought in New Mexico; discuss impacts of drought on the state’s human water user communities and environment; discuss in brief the priority call and water …

Priority Administration, Ed Merta

Water Matters!

Since the turn of the twenty first century, drought conditions have frequently stricken much of New Mexico. Such intervals of extreme dryness have been a permanent, recurring feature of the state’s climate for at least two thousand years, according to tree ring data and other scientific evidence. Some of these past droughts lasted for decades, exceeding in severity the Dust Bowl of the 1930sand the great New Mexico drought of the 1950s. Today, climate change models indicate that the Southwest will likely become even hotter, potentially making future droughts in New Mexico more extreme. Managing water shortages promises to become …


Active Water Resource Management, Paul Bossert, Gregory C. Ridgley Jan 2014

Active Water Resource Management, Paul Bossert, Gregory C. Ridgley

Water Matters!

For decades, most of the waters of the State of New Mexico have been the subject of water rights adjudications to establish all the water rights. Stream systems and sub-basins geographically define the adjudications. There are twelve active cases. However, complete adjudication of all New Mexico water rights is still many years away. Meanwhile, water use in the state has evolved.New water users increasingly look to acquire existing water rights rather than developing new rights. Decisions on administration, distribution, and redistribution of water have to be made.

It was widely held, though not unanimously, that the State Engineer needed greater …


Domestic Wells, Paul Bossert, Sarah Armstrong Jan 2014

Domestic Wells, Paul Bossert, Sarah Armstrong

Water Matters!

The domestic well statutes direct that the State Engineer “shall” issue a permit for certain types of temporary or low volume wells, including wells for household use. For the past fifty-five years, the Office of the State Engineer (OSE) has interpreted this to mean that such permits are granted with no evaluation, public notice, or hearing.


Water For New Mexico Rivers, Beth Bardwell, Adrian Oglesby Jan 2014

Water For New Mexico Rivers, Beth Bardwell, Adrian Oglesby

Water Matters!

The Rio Grande, the Pecos, the Gila, the San Juan, the Canadian—New Mexico’s rivers are synonymous with the state’s culture and natural heritage. New Mexicans overwhelmingly care about the health of the state’s rivers and that includes flows to support fish and river dependent wildlife. Rivers, wetlands, and riparian areas comprise a very small part of our landscape—a mere 1 percent. This 1 percent plays an essential role in renewing the state’s water supply for its two million residents; for sustaining the state’s second largest industry—tourism; for producing food and fiber; and for sustaining New Mexico’s web of life. Eighty …
