The Figure Of Bitu-Man, Paul Royster Oct 2014

The Figure Of Bitu-Man, Paul Royster

University of Nebraska-Lincoln Libraries: Faculty Publications

The ominously imposing figure in the above illustration is “the Syncrude bird deterrent device, locally known as ‘Bitu-man’.” He stands (or stood—the original image was from the late 1970s) in the tailings pond of the Syncrude Canada Ltd. oil sands mining operation along the Athabasca River near Fort McMurray in northeastern Alberta. That operation surface mines (i.e., strip mines) bitumen-impregnated sand, processes it with hot water and steam, and discharges the liquid effluent or “tailings” into a pond covering roughly 3000 hectares (11 square miles). (Google Map coordinates: 56.9°N, -111.3° W). Residue bitumen collects on the surface and poses a …

The Effects Of Altitude And Micro-Spatial Habitats On The Physiognomic Characteristics Of Syzygium Guineense In Mazumbai Forest Reserve, Erin Brynn Zalmanek Oct 2014

The Effects Of Altitude And Micro-Spatial Habitats On The Physiognomic Characteristics Of Syzygium Guineense In Mazumbai Forest Reserve, Erin Brynn Zalmanek

Independent Study Project (ISP) Collection

In order to examine the affects that altitude and micro-spatial habitat have on the physiognomy of Syzygium Guineense; buttress sphere size, number of buttresses, relative size of the buttresses, DBH, and height were measured in three different altitudinal bands (1400 - 1500 m, 1500 - 1600 m, and 1600 - 1700 m) and three different habits portraying concave, convex, and intermediate landscapes. Micro-spatial habits showed to have weak to no effect on all measured physiognomic variables giving insignificant p-values according to ANOVA. However, correlation tests against leaf litter depth and slope showed to have some relation to the size and …


Land Rights Among Subsistence Farmers: An Examination Of Madagascar’S Land Reform And Prevailing Systems Of Land Tenure In Betafo, Taylor Crowl Oct 2014

Land Rights Among Subsistence Farmers: An Examination Of Madagascar’S Land Reform And Prevailing Systems Of Land Tenure In Betafo, Taylor Crowl

Independent Study Project (ISP) Collection

In Madagascar, legal systems of land tenure have been inaccessible for the vast majority of the rural population. This has stranded millions of subsistence farmers in a sense of insecurity, as they lack legal rights for the property that they have farmed for generations. Madagascar’s land reform, launched in 2005, attempted to change these exclusionary tenure practices. This reform —known as the Plan National Foncier—created land certificates and local land offices in an attempt to make legal land tenure financially, geographically, and logistically accessible to the local population. This study discusses the successes, failures, and unforeseen consequences of Madagascar’s land …


The Mechanical And Social Feasibility Of Using Biogas To Fuel An Essential Oil Distillation Unit In The Rural Commune Of Ankarimbelo, Madagascar, Hannah Nesser Oct 2014

The Mechanical And Social Feasibility Of Using Biogas To Fuel An Essential Oil Distillation Unit In The Rural Commune Of Ankarimbelo, Madagascar, Hannah Nesser

Independent Study Project (ISP) Collection

The rural commune of Ankarimbelo is located on the edge of the Ikongo Rainforest Corridor in southeastern Madagascar. The commune’s remote location, an increasing population, and the prohibition of farming in the rainforest corridor have contributed to extreme poverty. In an attempt to mitigate these effects, the Malagasy NGO Ny Tanintsika has implemented an essential oils distillation plant as an alternative livelihood project. While the project may provide needed income to local populations, thereby diverting destructive agriculture practices such as tavy, or slash-and-burn agriculture, the distillation of essential oils still requires that firewood be burned. Over the course of …


Investment Opportunities In Solar-Powered Lighting For Small Rural Shops In Zanzibar, Alexander Cheston Oct 2014

Investment Opportunities In Solar-Powered Lighting For Small Rural Shops In Zanzibar, Alexander Cheston

Independent Study Project (ISP) Collection

Small shop-owners in rural Zanzibar, Tanzania were surveyed on their shops lighting fixtures and requirements to determine whether using a solar home system to power the shops lights would be a profitable investment. The shops surveyed in 4 grid connected rural villages in Zanzibar had very similar requirements, and a high-quality, affordable solar home system was designed to meet the requirements of the majority of these shops. Potential savings were calculated for each shop that replaced its current lighting fixture with a solar home system. 20% of the shops surveyed were found to potentially profit from investing in the solar …


Feasibility Of A Mangrove-Based Carbon Business In Makoba Bay, Unguja, Zanzibar, Janice Liang Oct 2014

Feasibility Of A Mangrove-Based Carbon Business In Makoba Bay, Unguja, Zanzibar, Janice Liang

Independent Study Project (ISP) Collection

Mangrove ecosystems, along with other coastal vegetation, have tremendous potential to be abundant carbon sinks. With the prospect of carbon sequestered in coastal ecosystems starting to be explored in carbon credit markets, this study attempts to assess the feasibility of a mangrove-based carbon business in Makoba Bay, Unguja, Zanzibar. An aboveground carbon estimation demonstrates that the mangrove forest of Makoba Bay is a recovering ecosystem, but has the potential to be initiated into a program such as REDD+ in the future. Social surveys in both Makoba Bay and Chwaka Bay also indicate that a number of improvements would have to …

Sharks Aren’T The Only Fish To Be Afraid Of… A Survey Of Serranidae Species Of Genus Aethaloperca, Anyperodon, Cephalopholis, Epinephelus, And Plectropomus On Chumbe Island, Zanzibar, Tanzania, Kimberly D. Nesbitt

Independent Study Project (ISP) Collection

A census as well as behavioral analysis of six grouper (Serranidae) species was conducted on Chumbe Island off the coast of Unguja, Zanzibar, Tanzania during October and November 2014. The six species were counted, divided into size classes, and behavioral notes were taken on the individuals observed on both the western drop-off of Chumbe Island’s reef as well as the back, shallower reef. Results showed that larger individuals, as well as species that grow larger, inhabit the deeper waters of the drop-off, while smaller species and juveniles inhabit the shallower back reef. The Brown Marbled (Epinephelus fuscoguttatus) and …


Connections Between Student Explanations And Arguments From Evidence About Plant Growth, Jenny Dauer, Jennifer H. Doherty, Allison L. Freed, Charles W. Anderson Oct 2014

Connections Between Student Explanations And Arguments From Evidence About Plant Growth, Jenny Dauer, Jennifer H. Doherty, Allison L. Freed, Charles W. Anderson

School of Natural Resources: Faculty Publications

We investigate how students connect explanations and arguments from evidence about plant growth and metabolism—two key practices described by the Next Generation Science Standards. This study reports analyses of interviews with 22 middle and high school students postinstruction, focusing on how their sense-making strategies led them to interpret—or misinterpret—scientific explanations and arguments from evidence. The principles of conservation of matter and energy can provide a framework for making sense of phenomena, but our results show that some students reasoned about plant growth as an action enabled by water, air, sunlight, and soil rather than a process of matter and energy …

The Optimal Foraging Of Equus Burchelli At Enashiva Nature Refuge, Edward Haubenreiser Oct 2014

The Optimal Foraging Of Equus Burchelli At Enashiva Nature Refuge, Edward Haubenreiser

Independent Study Project (ISP) Collection

Within the country of Tanzania lies a vast ecosystem known as the Serengeti. This unique landscape, primarily of grasslands and woodlands, shapes the seasonal feeding habits of the abundant wildlife that call the area home. While these feeding habits on a large spatial scale are well understood, such behavior within a specie’s specific environment remains of interest. With the theory of optimal foraging in mind, which considers how animals should look for and select food (Green, 1990), I studied the foraging habits of resident Burchell’s zebra (Equus burchelli) by observing if they move and forage among distinct resource …


Migratory Ecology Of Sea Turtles, Nathan Jack Robinson Oct 2014

Migratory Ecology Of Sea Turtles, Nathan Jack Robinson

Open Access Dissertations

Establishing the movement patterns of free-ranging animals is imperative to understanding their behavior and ecology, and is often necessary for designing effective conservation-strategies. This is especially true for migratory species, such as sea turtles, whose long-distance movements form a major component of their life history. In this thesis, I investigated which factors are driving the migratory behavior of the leatherback turtleDermochelys coriacea. Firstly, I examined whether the timing of the nesting season (nesting phenology) is influenced by oceanographic conditions along the pre-nesting migratory route or by variation in population structure. The discovery that nesting phenology appears more influenced by …


Walkable Gettysburg— How Pedestrian Friendly Is The Borough Of Gettysburg, Pennsylvania?, Samuel C. Gilvarg, Shane A. Kesnig Oct 2014

Walkable Gettysburg— How Pedestrian Friendly Is The Borough Of Gettysburg, Pennsylvania?, Samuel C. Gilvarg, Shane A. Kesnig

Student Publications

Walkability is a measure of how easily pedestrians can reach a variety of destinations via walking. Greater walkability has been linked to several benefits, including improvements in human health, economic stimulus, and improved air quality. We surveyed 37 blocks in Gettysburg, Pennsylvania to record the presence of 13 design factors such as street trees and pedestrian oriented amenities that have been shown to encourage walking. These results were then compared with the Walk Score from walkscore.com, a common measurement tool of walkability. Based on the surveys, we calculated a design quality score (DQI) for each block. There was no correlation …


What Drives Car Attitudes: An Analysis Of How Demographics And Environmental Views Relate To Car Attitudes, Kelly M. Gross, Alexandra S. Isaacson, Brian J.B. Lonabocker Oct 2014

What Drives Car Attitudes: An Analysis Of How Demographics And Environmental Views Relate To Car Attitudes, Kelly M. Gross, Alexandra S. Isaacson, Brian J.B. Lonabocker

Student Publications

Successfully marketing new, clean, car technologies to consumers requires an advertising strategy that fits consumers’ priorities and attitudes towards cars. We created a survey to study how attitudes towards cars are associated with demographics and environmental views. Our study examined car preferences and environmental concerns of a sample of Gettysburg College students in comparison to a national sample obtained from Amazon’s Mechanical Turk. Overall, we concluded that environmental beliefs are a significantly better prediction of car behaviors than demographics. We found that on average people would pay more for a car with a higher fuel economy, but not enough to …


Palm Reading: Predicting The Future Of Four Threatened Palm Species At Pointe À Larrée, Eastern Madagascar, Eva Colberg Oct 2014

Palm Reading: Predicting The Future Of Four Threatened Palm Species At Pointe À Larrée, Eastern Madagascar, Eva Colberg

Independent Study Project (ISP) Collection

Madagascar has one of the highest concentrations of palm diversity in the world, with 195 species, 192 of which are endemic, but just as for the rest of the island’s natural resources, the future of these palms is at stake. In fact, 83% of the country’s endemic palms qualify as threatened following the most recent version of IUCN Red List criteria, version 3.1, yet 28 are not even found within protected areas. One area awaiting government protection, MBG’s Pointe à Larrée project, is home to 18 different palm species, 11 of which are threatened. This study took sample counts to …


Comparison Of Coral Reef Health: Lokobe National Park And Tanikely National Park, Northwest Madagascar, Kailani Acosta Oct 2014

Comparison Of Coral Reef Health: Lokobe National Park And Tanikely National Park, Northwest Madagascar, Kailani Acosta

Independent Study Project (ISP) Collection

Coral reefs are microcosms of biodiversity and life. They are home to about a quarter of all marine life, yet amount to only about 1% of the world’s marine environment. Coral reefs are very vulnerable ecosystems; there are numerous threats to their health, such as damage by echinoderm and fish feeding, natural disasters, coral illness and bleaching events. Coral health fluctuates according to many of these factors and as a result of the fragile symbiotic balance between zooxanthellae algae and corals. Subsequently, coral health is an essential topic for analysis and assessment.

Coral reefs were assessed in Lokobe National Park, …

Environment and Society Faculty Publications

This report provides a summary of the main results of a household baseline survey carried out in late 2013 in four village development committees (VDC) in Bajura District. A total of 320 households were surveyed with 80 per VDC. Two of the VDCs have been subsequently targeted for interventions related to climate change adaptation, while two VDCs have voluntary agreed to serving as paired “controls.” This baseline survey was undertaken as part of a study entitled, ‘Improving the Resilience of Mixed Farm Systems to Pending Climate Change in Far Western Nepal’, conducted by USU and HKI. The baseline survey was …


Predictors Patterns And Processes Of Extinction Risk In Porgies And Seabreams (Family: Sparidae), Mia Theresa B. Conteros Oct 2014

Predictors Patterns And Processes Of Extinction Risk In Porgies And Seabreams (Family: Sparidae), Mia Theresa B. Conteros

Biological Sciences Theses & Dissertations

A variety of human-induced changes are having profound impacts on the marine environment, and no area on the planet remains unaffected by the detrimental effects of our activities. These stressors can potentially lead to synergistic effects, causing accelerated biodiversity loss and diminished ecosystem functioning. Identification and understanding of the factors that drive species to heightened risk of extinction are important goals in conservation.

The Sparidae are commercially important and ecologically complex marine fishes; global extinction risk assessments using the IUCN Red List of Threatened Species methodology show that 9% (13 species) have increased vulnerability to population declines from intense fishing …

Learning From Conservation Planning For The U.S. National Wildlife Refuges, Robert L. Fischman, Vicky J. Meretsky

Articles by Maurer Faculty

The U.S. National Wildlife Refuge System has nearly completed its first round of unit-level, comprehensive conservation plans (CCPs) and will soon begin required revisions. Laws and policies governing refuge planning emphasize ecological integrity, landscape-scale conservation, and adaptive management. We evaluated 185 CCPs completed during 2005–2011, which cover 324 of 555 national wildlife refuges. We reviewed CCP prescriptions addressing 5 common conservation issues (habitat and game, nongame, imperiled, and invasive species) and 3 specialized topics (landscape-scale conservation, climate change, and environmental quality). Common conservation issues received prescriptions in >90% of CCPs. Specialized topics received more variable treatment. Prescriptions for aquatic connectivity, …


Warming, Competition, And Bromus Tectorum Population Growth Across An Elevation Gradient, Aldo Compagnoni, Peter B. Adler Sep 2014

Warming, Competition, And Bromus Tectorum Population Growth Across An Elevation Gradient, Aldo Compagnoni, Peter B. Adler

Green Canyon Environmental Research Area, Logan Utah

Cheatgrass (Bromus tectorum) is one of the most problematic invasive plant species in North America and climate change threatens to exacerbate its impacts. We conducted a two‐year field experiment to test the effect of warming, competition, and seed source on cheatgrass performance across an elevation gradient in northern Utah. We hypothesized that warming would increase cheatgrass performance, but that warming effects would be limited by competing vegetation and by local adaptation of cheatgrass seed sources. The warming treatment relied on open top chambers, we removed vegetation to assess the effect of competition from neighboring vegetation, and we reciprocally …


The Status Of Fishes In The Missouri River, Nebraska: Shovelnose Sturgeon (Scaphirhynchus Platorynchus), Kirk D. Steffensen, Sam Stukel, Dane A. Shuman Sep 2014

The Status Of Fishes In The Missouri River, Nebraska: Shovelnose Sturgeon (Scaphirhynchus Platorynchus), Kirk D. Steffensen, Sam Stukel, Dane A. Shuman

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

The Shovelnose Sturgeon Scaphirhynchus platorynchus remains the most abundant riverine sturgeon species in North American despite the anthropogenic modifications that have occurred throughout their historic range; however, their populations have declined throughout Nebraska since the construction of Fort Randall and Gavins Point Dams. Therefore, the objective of this study was to present the current status of Shovelnose Sturgeon in the Missouri River along Nebraska’s border. Data was acquired from 2003 to 2012 from all reaches of the Missouri River along Nebraska’s eastern border. Catch rates of Shovelnose Sturgeon increased in a downstream trend and were highest in the reach below …


Damming Brazil, Thyra Brody Sep 2014

Damming Brazil, Thyra Brody

e-Research: A Journal of Undergraduate Work

Hydroelectric power is often considered a safe and clean alternative to the combustion of fossil fuels. Although the consequences to the air and atmosphere are lower, damming large rivers in the jungles of Brazil have a significant impact on indigenous populations and environmental ecosystems. This article examines such fallout and calls out for equity, and social and environmental justice. As the fuel of the last century burns out the hectic scramble for a tenable alternative is becoming an increasingly serious question mark. We would do well for ourselves, and future generations, to try and solve the environmental issues associated with …

Macroinvertebrate Prey Availability And Food Web Dynamics Of Nonnative Trout In A Colorado River Tributary, Grand Canyon, Daniel P. Whiting, Craig P. Paukert, Brian D. Healy, Jonathan Spurgeon Sep 2014

Macroinvertebrate Prey Availability And Food Web Dynamics Of Nonnative Trout In A Colorado River Tributary, Grand Canyon, Daniel P. Whiting, Craig P. Paukert, Brian D. Healy, Jonathan Spurgeon

School of Natural Resources: Faculty Publications

Nonnative fishes have been linked to the decline of native fishes and may affect aquatic food webs through direct and indirect pathways. These concerns have led to efforts to remove nonnative Brown and Rainbow Trout, which are abundant in tributaries of the Colorado River, to enhance native fish communities. We sampled fish, benthic, and drifting macroinvertebrates in November 2010, January 2011, June 2011, and September 2011 to assess resource availability and to evaluate the effects of nonnative Brown and Rainbow Trout in a tributary of the Colorado River in the Grand Canyon. We evaluated trout diets from stomach samples collected …

This is not an ordinary conference, full of dry presentations or heated policy debates. Instead, this will be a full-throated love song to wild country. We have brought …


An Assessment Of The Energy Generation Potential Of Photovoltaic Systems In Cameroon Using Satellite-Derived Solar Radiation Datasets, Lacour Ayompe, Aidan Duffy Sep 2014

An Assessment Of The Energy Generation Potential Of Photovoltaic Systems In Cameroon Using Satellite-Derived Solar Radiation Datasets, Lacour Ayompe, Aidan Duffy

Articles

Cameroon like most developing countries does not have a reliable network of surface observation stations for collecting weather data. This has been a major drawback for accurate assessment of the energy generation potential of photovoltaic systems in Cameroon. A viable alternative is to obtain site-specific solar irradiation from satellite-derived datasets. In this paper, the energy output, capacity factor and performance ratio of photovoltaic systems in 33 locations spread around ten regions in Cameroon have been evaluated using monthly average daily global horizontal solar irradiation from long-term satellitederived data available in Solar GIS software. An economic assessment revealed that a simple …


Fluid Properties In The Formation Of High-Grade Iron Ore In Northern Minnesota, Elizabeth Drommerhausen Aug 2014

Fluid Properties In The Formation Of High-Grade Iron Ore In Northern Minnesota, Elizabeth Drommerhausen

Journal of Undergraduate Research at Minnesota State University, Mankato

The Mesabi Iron Range in Northern Minnesota has been a major producer of iron ore for over 100 years. Production has been from the 1.85 – billion-year –old Biwabik Iron Formation, an iron-rich sedimentary rock that is tilted gently to the south. Most of the known high-grade ore lies near the surface and has been already mined. Determining whether more high-grade ore may lie at depth could have significant economic impact on the mining industry in northern Minnesota. To evaluate the likelihood of finding more high-grade iron ore deeper underground, it is important to determine the source of the fluids …
