The Role Of Interdisciplinary Gis And Data Curation Librarians In Enhancing Authentic Scientific Research In The Classroom, Benjamin D. Branch, Michael Fosmire

Libraries Faculty and Staff Presentations

Data science is a recently evolved area of scientific inquiry, where data, often collected by others, is analyzed by independent investigators to draw new conclusions. As such, data literacy needs to be incorporated into authentic research activities. The earth sciences in particular have a trove of data that resides in national data centers as well as individual investigators’ labs, which can be repurposed to provide the inputs for students to make their own inquiries into the data. With the amount of data available, students can make more substantive conclusions than if relying just on data they’ve collected themselves.

Examining Land Use/Land Cover Change And Potential Causal Factors In The Context Of Climate Change In Sagarmatha National Park, Nepal, Kamal Humagain

Masters Theses & Specialist Projects

In the context of growing tourism and global warming, the fragile landscape of the Himalayas is under immense pressure because of rapid land cover changes in developing countries like Nepal. Remotely sensed data combined with ethnographic knowledge are useful tools for studying such changes. The quantitative change can be measured analyzing satellite images whereas local people’s perceptions provide supportive information. To measure such changes in Sagarmatha National Park of Nepal, Multispectral Scanner (MSS) and Thematic Mapper (TM) images since 1972 were used. Normalized Difference Vegetation Index (NDVI) was calculated for different elevation classes and land cover types. These measurements, along …

Teleconnective Influences On The Strength Of Post-Tropical Cyclones, Jeremy Young

Masters Theses & Specialist Projects

Over the 1951-2009 time period, 47% of all tropical systems in the Atlantic Basin transitioned to post-tropical storms. These storms are capable of producing hurricaneforce winds, torrential, flooding rains and storm surge that floods coastal areas. This study adds to previous climatological work by completing a case-study of Hurricane Ike (2008) and examining how teleconnections such as the El Niño Southern Oscillation (ENSO), the Madden-Julian Oscillation (MJO), the Atlantic Multidecadal Oscillation (AMO) and the Pacific Decadal Oscillation (PDO) contribute to the strength of a transitioning post-tropical storm. T-tests performed show strong statistical relationships between an increase (decrease) in post-tropical storm …

Inter-Species Interactions: Effects Of Spatial Proximity Of Breeding Burrowing Owls (Athene Cunicularia) And Mountain Plovers (Charadrius Montanus) On Mountain Plover Nest Success, Lindsey Messinger

Geography and the Environment: Graduate Student Capstones

Predator-prey interactions are complex and direct interactions between predator-prey pairs are difficult to distinguish due to direct and indirect effects of additional predator-prey interactions. While most studies evaluating the impact of predators on prey concentrate on consumption (mortality of prey caused by a predator), there are a variety of interactions that take place between predators and prey that may not result in mortality. These in direct impacts of predation have been found to influence micro- and macro- habitat use, time allocation patterns, species distribution, population growth, and species interactions and can be just as strong or stronger than consumptive effects.

Sustainability creates and maintains the conditions under which humans and nature can exist in productive harmony, that permits fulfilling the social, economic, and other requirements of present and future.

Using Landscape Pattern Metrics To Characterize Ecoregions, Martha Isabel Posada Posada

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

Ecological regions, or ecoregions, are areas that exhibit “relative homogeneity in ecosystems”. The principal objective of this research was to determine if and how landscape structure (quantified by landscape pattern metrics) may be related to ecoregions defined using Omernik’s approach to ecoregionalization. Nine key landscape pattern metrics (number or LULC classes and the proportion of each class, number of patches, mean patch size and area-weighted fractal dimension, perimeter-area fractal dimension, contagion, mean Euclidean nearest neighbor distance and interspersion and juxtaposition index) where used to asses landscape structure in a sample of 26 Omernik Level III ecoregions located in the central …

Government Documents On Rare Earth Minerals, Bert Chapman

Libraries Faculty and Staff Presentations

Rare earth minerals contain unique chemical and physical properties such as lanthanum, are found in small concentrations, need extensive precise processes to separate, and are critical components of modern technologies such as laser guidance systems, personal electronics such as Blackberries, and satellites. The U.S. has some rare earth resources, but is heavily dependent on access to them from from Afghanistan, Bolivia, and China. Losing access to these resources would have significant economic, military, and political implications. This presentation will highlight government information resources on rare earth minerals from agencies such as the Department of Energy (DOE), Department of Defense (DOD), …

The Role Of Landscape Connectivity In Planning And Implementing Conservation And Restoration Priorities. Issues In Ecology, Doborah Rudnick, Sadie J. Ryan, Paul Beier, Samual A. Cushman, Fred Dieffenbach, Clinton Epps, Leah R. Gerber, Joel N. Hartter, Jeff S. Jenness, Julia Kintsch, Adina M. Merenlender, Ryan M. Perkl, Damian V. Perziosi, Stephen C. Trombulack

Geography

Landscape connectivity, the extent to which a landscape facilitates the movements of organisms and their genes, faces critical threats from both fragmentation and habitat loss. Many conservation efforts focus on protecting and enhancing connectivity to offset the impacts of habitat loss and fragmentation on biodiversity conservation, and to increase the resilience of reserve networks to potential threats associated with climate change. Loss of connectivity can reduce the size and quality of available habitat, impede and disrupt movement (including dispersal) to new habitats, and affect seasonal migration patterns. These changes can lead, in turn, to detrimental effects for populations and species, …

Multi-Temporal Analysis Of Crop Biomass Using Selected Environmental Variables And Remote Sensing Derived Indices, Nwakaku M. Ajaere

Department of Geography: Dissertations, Theses, and Student Research

Measuring biomass in crops is important for yield prediction, nutrient management and analysis of carbon sequestration. Studying crop phenology via biomass can also provide insight into not only the state of the ecosystem but also environmental factors which may affect crop growth. Remote sensing techniques, as an alternative to traditional in-situ sampling methods for biomass assessment, provide potentially more efficient data acquisition and cost-effective procedures. Numerous vegetation indices (VI) have been developed which use spectral reflectance data to measure plant biophysical characteristics. The first objective of this research was to examine the correlation between crop biomass and selected environmental variables …

Amazonian States Map Threatened Borderlands, David S. Salisbury, A. William Flores De Melo, Jorge Vela Alvarado, Bertha Balbin Ordaya

Geography and the Environment Faculty Publications

Recently, the Regional Initiative to Integrate South America has begun promoting a transboundary road that would bisect the forested borderlands and connect the two largest cities in the region, while the state governments seek to promote a direct ecological railroad alternative. Both transportation initiatives promise to alter forests and rivers and transform economies and cultures, but these projects also lack the base geographic information necessary to understand their potential transboundary impacts and benefits.

Towards Developing Indicators Of Environmental Sustainability For Kathmandu, Nepal, Published Version, Ambika P. Adhikari

Himalayan Research Papers Archive

Sustainability is now considered one of the key objectives in urban planning. However, due to inappropriate planning, weak institutions, limitation of resources, and poor implementation of policies, many big cities in the developing countries have become even less environmentally, economically and socially sustainable than they were in the past. Historically, the Kathmandu valley enjoyed a unique tradition, rich heritage and a moderate state of sustainability in all areas, particularly in the environmental arena. However, the rapidly expanding and modernizing cities in the valley are facing serious problems of sustainability in all fronts: economic, social, environmental and ecological. Whereas environmental and …

Hydrologic Modeling To Examine Land Use Change Impacts (1970’S And 2005) On The Sediment Yield And Flow Regime In Cayuga Creek, Niagara County, New York, Kimly Reth

Multidisciplinary Studies Theses

This research aims to assess the water quality and the land use change impacts on sediment concentration and flow regime in Cayuga Creek, Niagara County, NY for two land use periods, 1970’s and 2005. The 1970’s land use, classified by the USGS, had a significant error. Therefore, the scenario of sediment yield and discharge level to land use change is more of a “what if” since the 1970’s land use was classified incorrectly. The Soil and Water Assessment Tool (SWAT)was used to simulate flows and sediment concentrations for the two land use scenarios using the same rainfall data at the …

Prototype For Monitoring And Forecasting Fall Foliage Coloration In Real Time From Satellite Data, Xiaoyang Zhang, Mitchell D. Goldberg, Yunyue Yu

GSCE Faculty Publications

While determining vegetation phenology from the time series of historical satellite data has been widely investigated throughout the last decade, little effort has been devoted to real-time monitoring and short-term forecasting. The latter is more important for numerical weather modeling, ecosystem forecasting, forest and crop management, and health risk warning. In this study we developed a prototype approach for the real-time monitoring and short-term forecasting of fall foliage status (including low coloration, moderate coloration, near-peak coloration, peak coloration, and post-peak coloration) using temporal satellite observations. The algorithm combined the climatology of vegetation phenology and temporally available satellite observations to establish …

Remote Sensing-Based Time Series Models For Malaria Early Warning In The Highlands Of Ethiopia, A. Midekisa, G. Senay, G. M. Henebry, P. Semuniguse, M. C. Wimberly

Natural Resource Management Faculty Publications

Background

Malaria is one of the leading public health problems in most of sub-Saharan Africa, particularly in Ethiopia. Almost all demographic groups are at risk of malaria because of seasonal and unstable transmission of the disease. Therefore, there is a need to develop malaria early-warning systems to enhance public health decision making for control and prevention of malaria epidemics. Data from orbiting earth-observing sensors can monitor environmental risk factors that trigger malaria epidemics. Remotely sensed environmental indicators were used to examine the influences of climatic and environmental variability on temporal patterns of malaria cases in the Amhara region of Ethiopia. …

An Integrated Approach For Developing Adaptation Strategies In Climate Planning: A Case Study Of Vulnerability In Dukes County, Massachusetts, Jonathan Pollak

Master's Theses

Climate Action Plans (CAP’s) are recent innovations in policy that have been catalyzed by a need to adjust the relationship between human activity and the Earth’s climate system. CAP’s often are composed of methods to mitigate greenhouse gas emissions in addition to adaptation strategies. Research indicates, however, that many plans focus on mitigation strategies while adaptation policies related to predicted changes caused by climate change are often overlooked. This thesis presents an integrative framework for locating areas that are in need of adaptation strategies through a GIS based decision support system that visualizes vulnerability. It is operationalized through an empirical …

The Paleoecology Of A Morrowan Fossil Bed, Washington Mountain, Fayetteville, Arkansas, Steven Hamlin

Geosciences Undergraduate Honors Theses

This study began with a general survey of Washington Mountain that identified the stratigraphic units outcropping. While doing so, the Wedington Member of the Fayetteville Shale and the Pitkin Limestone were both found on the north face. Both units had been previously mapped as pinching out further south. The discovery of a fossil bed in the upper portion of the Cane Hill on Washington Mountain provided a rare opportunity to study the ecology of early Pennsylvanian fauna. Though the sandstone bed was poorly preserved, 14 separate genera were identified and their ecological niches were compared in an effort to establish …

Role Of Vegetation And Environmental Characteristics On Slope Stability In Northwest Arkansas, Michael Maguigan

Graduate Theses and Dissertations

Slope failure continues to pose risks to society because knowledge of environmental factors and their interactions are unclear and possibly misunderstood. This misunderstanding leads to generalizations about slope failure susceptibility mapping, despite knowing that slope failures are likely the result of an extensively complex set of interactions among a number of environmental, edaphic, and geomorphic characteristics. Therefore a series of experiments were conducted to investigate the effects of slope, soil texture, vegetation cover, bedrock permeability, and compaction,. A wooden flume with a slope face 1 m wide by 1.5 m long with a 10 cm toe was constructed to contain …

Arsenic Contamination In Groundwater In Vietnam: An Overview And Analysis Of The Historical, Cultural, Economic, And Political Parameters In The Success Of Various Mitigation Options, Thuy M. Ly

Pomona Senior Theses

Although arsenic is naturally present in the environment, 99% of human exposure to arsenic is through ingestion. Throughout history, arsenic is known as “the king of poisons”; it is mutagenic, carcinogenic, and teratogenic. Even in smaller concentrations, it accumulates in the body and takes decades before any physical symptoms of arsenic poisoning shows. According to the World Health Organization (WHO), the safe concentration of arsenic in drinking water is 10 µg/L. However, this limit is often times ignored until it is decades too late and people begin showing symptoms of having been poisoned.

This is the current situation for Vietnam, …

Assessment Of Land Use Suitability Based On Water Erosion Susceptibility In Medium-Sized Urban Areas Of The Metropolitan Region Of Santiago, Central Chile, Roberto Fernandez

Graduate Theses and Dissertations

Urban areas constitute complex spatial entities where biophysical and socioeconomic environments interact through processes that determine the distribution of land use in the territory. Given Chile's variety of landscapes, water erosion, and mass movement, and rapid expansion of its medium-sized cities, straightforward techniques for assessment of land use suitability are essential. Through evaluation of water erosion susceptibility, it is possible to efficiently determine suitability of land use in medium-sized cities and their adjacent environments. The adaptation and application of the Erosion Response Units (ERU) concept (Märker et al., 2001) in the cities of Colina and Melipilla, Metropolitan Region of …

Prospects For An International Charter "Space And Major Disaster" Remote Sensing Response To Drought Disasters - An Anhui, China Case Study, Joseph Burkhead

Masters Theses

Remote sensing is often leveraged during the response phase of disaster management to improve the situational awareness of decision-makers. The International Charter "Space and Major Disaster" (Charter) provides remote sensing support to non-spacefaring nations facing disasters such as earthquakes, floods and tsunamis. However, the Charter has never activated for a major drought disaster. Since droughts affect over half of the nearly 3 billion people that suffer from natural disasters annually, this study seeks to determine whether satellite remote sensing can be effectively employed according to the intent, capabilities, and limitations of the Charter to benefit officials responding to a major …
