Using Soil Geospatial Properties And Environments To Explore Microbial Diversity, Sharon Faye Smith

Graduate Theses and Dissertations

Soil microorganisms help maintain nutrient cycling, control carbon sequestration, impact plant productivity, and influence several soil chemical and physical properties; yet, the processes that control the microbial composition of soil and how environmental changes may affect the composition and activity of these organisms at different scales remains a difficult and intriguing puzzle for soil scientists, ecologists, and modelers. Wetlands are endangered and important ecosystems that provide several services, which are directly linked to soil function. However, few wetland assessments consider the soil environment and microbial ecology. Linking soil microbial community composition and distribution patterns to soil physio-chemical properties would provide …

Far-Right Extremism In America: A Geospatial Analysis Of Incident Distribution, Meredith Leann Lerma

Graduate Theses and Dissertations

There has been little empirical research on the spatial relationship of violent far-right extremism. Previous studies have only focused on portions of far-right violent incidents, such as homicides, or amalgamated all far-right extremist activity, including legal incidents. This study uses data from the Extremist Crime Database (ECDB) and Southern Poverty Law Center (SPLC) in a temporal frame of 2000 to 2018 to test the relationship of violent incidents against geographic and social factors. The goal is to explore the relationships between macro-level factors and violent far-right extremist incident. The research determines that the presence of hate groups, higher immigrant populations, …

Gentrification & The South Bronx: Demographic And Socioeconomic Transformations In Bronx Community District #1, Lawrence Cappello

Center for Latin American, Caribbean, and Latino Studies

Introduction:

In recent decades skyrocketing real estate values throughout New York City have prompted residents to seek out reasonably priced housing and speculative investment opportunities in traditionally poorer neighborhoods. This is commonly referred to as “gentrification."

This report examines the extent of gentrification in the South Bronx neighborhoods of Melrose, Mott Haven, and Port Morris – officially designated Bronx Community District #1 – widely known as one of New York City’s prominent Latino areas. It presents key socioeconomic and demographic trends between 1990 and 2017. It also looks at topics such as employment, income structures, poverty rates, language acquisition, race/ethnicity, …

However, a question still remains about how consistently his views …

Earth Observation And Sustainable Development Goals, Ramesh P. Singh

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

"Planet Earth is a dynamic body, which is home to 7.8 billion people, and strong interactions exist between the human population and the Earth’s different components (land, ocean, biosphere, cryosphere and atmosphere). The impacts of such interactions are observed from the day-to-day changes in weather, solar radiation, cloudy conditions, poor visibility, rainfall and frequency of natural hazards around the globe. The dynamic nature of the Earth is evident at the ocean coast through the ocean waves, the nature of these waves varies from day-to-day and also morning to evening. For example, the heights of waves can now be predicted through …

Brazilian Maize Yields Negatively Affected By Climate After Land Clearing, Stephanie A. Spera, Jonathan M. Winter, Trevor F. Partridge

Geography and the Environment Faculty Publications

To date, over 50% of the Brazilian Cerrado has been cleared predominantly for 11 agropastoral purposes. Here, we use the Weather Research and Forecasting model to run 15- 12 year climate simulations across Brazil with six land-cover scenarios: 1) before extensive land 13 clearing; 2) observed in 2016; 3) Cerrado replaced with single-cropped (soy) agriculture; 4) 14 Cerrado replaced with double-cropped (soy-maize) agriculture; 5) eastern Amazon replaced 15 with single-cropped agriculture; and 6) eastern Amazon replaced with double-cropped 16 agriculture. All land-clearing scenarios (2-6) contain significantly more growing season days 17 with temperatures that exceed critical temperature thresholds for maize. …

Survivorship Of The Reintroduced Kihansi Spray Toads Nectophrynoides Asperginis In A Soft Release Experiment At The Kihansi Gorge, Tanzania, Flora John Magige, Nassoro Mohamed

Journal of Humanities and Social Sciences

The Kihansi Spray Toad (KST) Nectophrynoides asperginis is endemic to the unique wetland habitat surrounding the Kihansi Falls, Tanzania, with which it was associated. The species was declared extinct in the wild in 2009 by the International Union for Conservation of Nature (IUCN), following the loss of its unique habitat due to the diversion of the Kihansi River for hydropower production. This study is an initial attempt to determine the survivorship and possible sources of mortality of newborn and adult KSTs placed in cages in their original habitat in the Upper Spray Wetland (USW) and Lower Spray Wetland (LSW) areas. …

A Multivariate Assessment Of Climate Change Projections Over South America Using Cmip5, Valerie Maria Thaler

Dissertations and Theses

A multivariate assessment of climate model projections over South America from the CMIP5 archive is presented. Change in near-surface temperature, precipitation, evapotranspiration, integrated water vapor transport (IVT), sea level pressure, and wind at multiple pressure levels is quantified across the multi-model suite and an assessment of model-to-model agreement on projected change performed. All models project warming by the mid- and late-21st century throughout the continent, with the highest magnitude projected over tropical regions. The CMIP5 models are in strong agreement that precipitation will decrease in all seasons over portions of Patagonia, especially along the northern portions of the current-climate mid-latitude …

Miller, Wenzhao Li, Hesham El-Askary, Ace Vincent B. Flandez, Joshua J. Dagoy, Joselito Francis A. Alcaria, Abdullajid U. Basali, Khaled A. Al-Abdulkader, Ronald A. Loughland, Mohamed A. Qurban

Mathematics, Physics, and Computer Science Faculty Articles and Research

Vegetation is an important ecological component of offshore islands in the Arabian Gulf (AG), which maintains long-term resilience of these islands. This is achieved by influencing sediment retention and moisture acquisition via condensation during periods of high humidity and by providing a variety of microhabitats for island fauna. The resilience of offshore islands’ ecosystems in the Saudi waters is important because they host the largest number of nesting hawksbill and green turtles in the AG. This study defines the characteristics and the long-term trends in vegetation cover of the offshore islands used by sea turtles as nesting grounds in the …

Assessing Adaptive Capacity To Climate And Population Change At The Urban-Rural Interface: Human-Water System Dynamics In The Hood River Valley, Oregon, Alexander Reid Ross

Dissertations and Theses

An exurban nook on the Oregon side of the Columbia River Gorge named after the Hood River that runs northward from the glaciers of Mount Hood to the confluence seems ideally poised for the kind of relaxed, natural lifestyle that once brought suburban areas their appeal. However, like other exurban areas, Hood River also lies at an uncertain fault-line between economic and environmental transformation in the U.S.'s exurbs.

This study maps the socio-economic and climatological transformations of exurban areas as they contend with different approaches to sustainability and resilience. To determine the major climate and development hazards facing exurban areas …

Wrack & Ruin: A Tale Of Tortured Trees, John T. Van Stan Ii, Albertus Tyasseta, Siloy, Graphic Artist

Earth, Environment & Sustainability: Faculty Bookshelf

Here, we visit a community of trees living along the Georgia coast, just above the high tide line, on a little lump of sand called a "hammock." This hammock plant community is battered by a hurricane. The plants that survive soon realize that they have fallen prey to a hydrological torture wrack - one composed of the salty corpses of their neighboring marsh plants (Spartina alterniflora). This sci comic is based on the publication, "Wrack and ruin: Legacy hydrologic effects of hurricane-deposited wrack..." (https://doi.org/10.1088/2515-7620/ab9527).

"Ni Hao" Is The New "Aloha": Asia's Rise In Tourism, Julianne Binns

Marriott Student Review

Asia has become one of the fastest growing areas in terms of travel and tourism. When it comes to investing in tourism (in ay form) one should keep a watchful eye on the region. This paper addresses the evidence of growth, reasons behind the growth, and what to expect in the future. As the region strengthens in economic power and shines light on its positives, more travelers are making their way to (or around) Asia. With coronavirus now being quelled in the region, it is only a matter of time before the numbers pick back up again. No doubt, the …

Wrack And Ruin: Legacy Hydrologic Effects Of Hurricane-Deposited Wrack On Hardwood-Hammock Coastal Islands, John T. Van Stan Ii, Scott T. Allen, Travis Swanson

Earth, Environment & Sustainability: Faculty Publications

Hurricanes can cause immediate catastrophic destruction of marsh vegetation and erosion of soils; however, they also have long-lasting ecological impacts. Those impacts include the deposition of tremendous amounts of saltmarsh litter ('wrack') onto upland ecosystems, the hydrologic effects of which have not previously been investigated. When Hurricane Irma battered the southeastern US coastline, widespread wrack deposition was reported (often exceeding 0.5 m depth), especially in vulnerable coastal hammock ecosystems: locally-elevated forests within the saltmarshes that rely on freshwater inputs from rain. We report the impacts of this deposited wrack, which has persisted for 2 years, on effective precipitation inputs to …
