Energía En Nuestras Manos: La Energía Renovable En Escala Local Y La Plurinacionalidad, Noah Stanton

Independent Study Project (ISP) Collection

Aunque la revolución ciudadana ha establecido el Ecuador como un país plurinacional con una consciencia ambiental, el régimen político actual está rechazando esta imagen del país. Frente este desafío, yo propongo que la energía renovable pueda ser una herramienta para ambos fortalecer la plurinacionalidad dentro del país y a la vez proteger el medio ambiente que lo sostiene. En la monografía, detallo cómo la energía renovable en escala local puede reforzar la autodeterminación de pueblos en el Ecuador. Luego, discuto las ventajas y desventajas de tres tipos de energía renovable: energía solar, energía eólica, y energía hídrica.

Pollution In Stone Town’S Coastal Waters: An Assessment Of Environmental Influences On Fecal Contamination, Socorro Lopez

Independent Study Project (ISP) Collection

Urbanized areas in Tanzania, including Zanzibar Town on Unguja, are struggling to deal with the large amount of waste generated by growing populations and increasing tourist industries. In 2010, the waters surrounding Stone Town, a subsection of Zanzibar Town, were found to be highly polluted by fecal waste. This study attempted to determine whether pollution has lessened or worsened in the past four years. Furthermore, environmental components of the coastal area, particularly tides, were tested in order to determine whether they had an impact on pollution in the waters. Using the membrane filtration method, mean enterococci were quantified in two …

The Conceptualization Of “Environmentalism” In Sagara, Emma Chapman

Independent Study Project (ISP) Collection

My study focused on the perceptions of “environmentalism” in Sagara, Tanzania and attempted to compare Sagaran concepts to those of a more Western model. My study also identified the “actors” that taught Sagarans about the environment. After finding that Sagarans held a strong resource conservation focus in their responses, I then focused on the details of their resource use to see whether what they have been taught about conservation has been actualized in their daily life. I predicted to find that Sagarans have a much more generalized and resource conservation focused definition of “environmentalism” and that their patterns of resource …

Gamba La Kasa: Using The Sea Turtle As A Flagship For Conservation Through Storytelling And Children's Literature, Eliza Hollister

Independent Study Project (ISP) Collection

The purpose of this study has been to educate the children and adults of Uzi Island on the importance of sea turtle conservation through storytelling and collaborative children's literature. This study's culminating product is a handmade children's book, written in both English and Swahili, entitled Turtle's Shell/Gamba La Kasa. A story from an Uzi elder was integrated into the book, as were illustrations gathered from the children of Uzi. Sea turtle conservation efforts are occurring all over the world through many methods, but this study is different from others because it acknowledges and utilizes the local knowledge and folklore in …

Population, Progeny And Power: Analyzing Population Growth, Family Planning And The Factors That Contribute To High Child Bearing Rates In Kizanda Village, Tanzania, Jade Enright

Independent Study Project (ISP) Collection

The population growth rate is reaching an astounding level in Tanzania and Eastern Africa. It is applying increasing pressure on things like social services, land availability, job opportunities, conservation and localized resources. This study looks at the perceptions of both men and women surrounding social and environmental factors contributing to the high population growth rate. It looks more specifically at factors including childbearing, birth control methods and their effectiveness, and how the birth rate correlates with changing quality of life. This study was conducted in Kizanda Village in the West Usambara Mountains of Northern Tanzania, a region following the trend …

Mama Nyani: A Study Of The Correlation Of Behaviors And Habitat In Papio Anubis, Madison Beran

Independent Study Project (ISP) Collection

As the population in Tanzania continues to grow more people are in search of jobs. In Northern Tanzania a village named Mto Wa Mbu is conveniently located directly adjacent to Lake Manyara National Park. With its good location and weather for crops, many people have moved there in hopes to earn some money from the 1 million tourists that visit Tanzania per year. As more people move to Mto Wa Mbu the pressure between animals and the people has increased. With the national park directly across the street from housing both animals and people can easily access each other’s homes. …

Stars, Long Fingers, And Signals: A Study On Grass Species Diversity, Density, Frequency, And Veld Analysis At Ndarakwai Wildlife Ranch, Reena Walker, Theresa Schaffner

Independent Study Project (ISP) Collection

This study was the first step to assessing veld quality and grass species diversity at Ndarakwai Wildlife Ranch in West Kilimanjaro, Tanzania in an effort to better inform management decisions that affect grasses and grazers. Our study was performed from April 5 to April 26, 2014. We utilized compass line quadrat method (n=600) in six sub-populations within three sample frames to achieve non-representative, random data set on richness, diversity, frequency, and density, with metadata from which we extrapolated veld indicators through secondary-source knowledge. Across all sample frames, we found 43 specimens: identified 29 to species, 7 to genus, and left …

Bioremediation Of Polluted Zanzibar Seawater: The Nutrient And Bacterial Bioextraction Potential Of Native Seaweeds And Bivalves, Katie Bergman

Independent Study Project (ISP) Collection

In Stone Town, Zanzibar, increasing populations and insufficient sewage treatment has greatly increased harmful levels of nutrients and anthropogenic-sourced contaminants along the city’s coastal waters. In this study, the nutrient and bacterial bioextractive abilities of local species of bivalves (A. antiquata, P. margaritifera) and seaweeds (E. denticulatum, U. reticulata) were examined in order to determine the potential for these species to remedy the local polluted waters. It was hypothesized that due to bivalves’ suspension-feeding activity, both species of bivalves would be able to decrease turbidity and fecal indicator bacteria (Enterococci) levels in sample polluted …

From Holy To Holistic: Working Towards Integrated Management Of The Bagmati River Corridor, Lauren Platman

Independent Study Project (ISP) Collection

The Bagmati and its tributaries have been an integral part of the Kathmandu Valley civilization. The river not only became a source of sustenance for the Valley's population but also gained religious-cultural significance. However, rapid urbanization and increasing industrial activities have transformed this once pristine river into an open sewer. Governmental organizations, NGOs, and community members are working towards improving the conditions of the Bagmati River through restoration projects and public awareness campaigns. Because of the large number of actors, collaboration on projects is vital in order to avoid duplication or conflict. After nearly thirty years of failed restoration projects …

Influencias Antropogénicas En El Mantenimiento De Los Senderos En El Género De Hormigas Corta Hojas Atta, Glen Zinck

Independent Study Project (ISP) Collection

Leaf-cutter ants have been shown to rigorously maintain their trunk trails throughout the year and regardless of if they have traffic. The behaviors of this clearing mechanism of the ants has been well-documented with different natural obstacles such as leaves and twigs, yet the comparative energy and time used by the ants with anthropogenic obstacles still remains unknown. In order to determine the differences in time and energy for moving these obstacles, both natural and artificial obstacles were tested in tandem during these trials. I used different sizes of blockers to see if the surface area and weight factored into …

School of Natural Resources: Faculty Publications

Anthropogenic changes to land cover (LCC) remain common, but continuing land scarcity promotes the widespread intensification of land management changes (LMC) to better satisfy societal demand for food, fibre, fuel and shelter. The biophysical effects of LCC on surface climate are largely understood, particularly for the boreal and tropical zones, but fewer studies have investigated the biophysical consequences of LMC; that is, anthropogenic modification without a change in land cover type. Harmonized analysis of ground measurements and remote sensing observations of both LCC and LMC revealed that, in the temperate zone, potential surface cooling from increased albedo is typically offset …

The Status Of Coastal Birds On Uzi Island: A Coastal Survey Of Birds And Their Interactions With Fishermen And Seaweed Farmers, Anna Curtis-Heald

Independent Study Project (ISP) Collection

Birds are useful environmental indicators and play important roles in the lives of people. A survey of coastal birds was completed around the shores of Uzi Island, Zanzibar. Intertidal flats surveyed at low tide proved to be the most diverse. Mangrove habitat surveyed at high tide was less diverse, yet a mangrove island hosted an abundance of roosting birds.

Although the coastal bird species found on Uzi are of “Least Concern” according to IUCN ratings, conservation of bird habitat, such as mangroves, is a vital step in maintaining biodiversity. Human subjects reported that fishermen and seaweed farmers do not disturb …

Arizona's Vulnerable Populations, Jonathan G.S. Koppell, Warren Prostollo, Jay Kittle, Arlan Colton, Kim Demarchi, Darryl Dobras, Susan Goldsmith, Billie Fidlin, Jim Holoway, Tara Jackson, Rita Maguire, Elizabeth Mcnamee, Patrick Mcwhortor, Ray Newton, Pat Norris, Steve Pedigo, Scott Rhodes, Fred Rosenfed, Chad Sampson, David Snider, Bob Strain, Marissa Theisen, Devan Wastchak, Terri Wogan, Larry Woods, Antonia Adams-Clement, Nina Babich, Andrea Banks, Eric Bjorklund, Luke Black, Luis De La Cruz-Parra, Richard Fabes, Felicia Ganther, Joseph Garcia, Maria Harper-Marinick, Kevin Hengehold, Lane Kenworthy, Julie Knapp, Kelly Mcgowan, Ray Ostos, Kathleen Perales, Suzanne Pfister, Michael S. Shafer, Julia Grace Smith, Ed Strong, Cynthia Zwick

Publications from President Jonathan G.S. Koppell

Arizona’s vulnerable populations are struggling on a daily basis but usually do so in silence, undetected by traditional radar and rankings, often unaware themselves of their high risk for being pushed or pulled into a full crisis. Ineligible for financial assistance under strict eligibility guidelines, they don’t qualify as poor because vulnerable populations are not yet in full crisis. To be clear, this report is not about the “poor,” at least not in the limited sense of the word. It is about our underemployed wage earners, our single-parent households, our deployed or returning military members, our under-educated and unskilled workforce, …

An Evaluation Of Two Traps And Sets For Trapping The Plains Pocket Gopher, Stephen M. Vantassel, Andrew J. Tyre, Scott E. Hygnstrom

School of Natural Resources: Faculty Publications

We investigated the efficiency of DK-1 and Macabee® pocket gopher (Geomys bursarius) traps placed in lateral tunnels in both open and closed tunnel sets in rangeland and nonirrigated alfalfa fields in Nebraska. We observed no statistical difference between the traps in capture efficiency when used in open, versus closed, tunnel sets. Trapping of pocket gophers was more effective in rangeland (probability of capture in a single tunnel system using 3 traps; 63%) than nonirrigated alfalfa fields (26%). We did not determine whether this variance was due to behavioral differences between Geomys bursarius and Geomys lutescens. We found that trapping pocket …

Examples Of Non-Noetherian Domains Inside Power Series Rings, William Heinzer, Christel Rotthaus, Sylvia Wiegand

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

Given a power series ring R∗ over a Noetherian integral domain R and an intermediate field L between R and the total quotient ring of R∗, the integral domain A = L ∩ R∗ often (but not always) inherits nice properties from R∗ such as the Noetherian property. For certain fields L it is possible to approximate A using a localization B of a particular nested union of polynomial rings over R associated to A; if B is Noetherian, then B = A. If B is not Noetherian, we can sometimes identify the prime ideals of B that are not …
