Cladophora Sp. Biosorption Of Metal-Contaminated Water, Rosamond R.M.S. Tshumah-Mutingwende, Fumitake Takahashi, Ewa Cukrowska, Julien Lusilao-Makiese

Applied Environmental Research

Artisanal and Small-scale Gold Mining (ASGM) activities employing the mercury amal-gamationtechnique have resulted in a significant drop in the quality of water from Ngwabalozi River, Zimbabwe. Mercury levels as high as 0.31 mg L-1have been reported in its waters and the low river pH (pH 3) favors proliferation of microorganisms responsible for methylmercury (a potent neurotoxin) formation. Thus, removal of mercury from contaminated systems is a priority. Therefore, the aim of this study is to develop a low-cost batch reactor for the removal of mercury from mercury contaminated acidic waters tomeet the World Health Organization (WHO) standard of 0.006 mg …

As trees are long-lived organisms, the impacts of climate change on forest communities may not be apparent on the time scale of years to decades. While lagged responses to environmental change are common in forested systems, potential for abrupt transitions under climate change may occur in environments where alternative vegetation states are influenced by disturbances, such as fire. The Klamath mountains (northern California and southwest Oregon, USA) are currently dominated by carbon rich and hyper-diverse temperate conifer forests, but climate change could disrupt the mechanisms promoting forest stability– regeneration and fire tolerance— via shifts in the fire regime in conjunction …

Devonian Stromatoporoid Interactions At The Falls Of The Ohio State Park, Clarksville, Indiana, Morgan Sierra Hall

Undergraduate Theses

Stromatoporoids are calcitic sponges that occurred in the fossil record from the Early Ordovician to Late Devonian period. These sponges interacted with other organisms, especially rugose and tabulate corals. Some corals appear to benefit from the rigidity of stromatoporoids in response to turbulent waters. Stromatoporoids and many corals went extinct during the Frasnian-Famennian crisis when paleoenvironmental parameters were shifting. Studying the relationships between these taxa may provide insight to their vulnerability during the extinction.

This research was performed at the Falls of the Ohio in Clarksville, Indiana. Organisms in the Coral Zone were studied using transect sampling. Each fossil along …

Dust deposition process was further examined with dust aerosols’ vertical distribution using satellite lidar data. Conversely, a negative correlation was found at 0–3 months lag between SST anomalies …

Olympic Success: Built, Born, Or Bought?, Jacob Ney

Celebrating Scholarship and Creativity Day (2018-)

During the Olympic Games, a ranked medal count often compares performance by country, but this system may be an unfair and inaccurate representation of Olympic success. To fairly balance how this success is measured, factors such as a country’s participation, population, and GDP must be considered. These choropleth, Robinson-projected world maps display normalizations of these factors using medal count and participant information from every summer Olympics since 1896, as well as data on each country’s current population and GDP.

Reframing Humans (Homo Sapiens) In International Biodiversity Law To Frame Protections For Climate Refugees, Jullee Kim

William & Mary Environmental Law and Policy Review

Currently, application of international environmental law assumes that humans are separate from nature. Yet, the terminology commonly adopted for persons displaced as a result of climate change, “climate refugees,” represents the ultimate expression of the nexus where impacts from both natural and human systems coalesce. “Climate” represents the physical conditions appearing as a result of climate change and altering a person’s home to render it no longer habitable. While suitability of the term “refugees” in the climate change context is debated, it represents the political and societal conditions forcing the person to flee from their home, potentially across national borders, …

Three Essays On Understanding Municipal Water Demand In The Western United States, Michael J. O'Donnell

Economics ETDs

Scarce water resources in the Western United States, in concert with population growth and climate change, constitute a need to better understand factors that impact water demand. In this dissertation, Chapter 1 provides cultural and historical context for water use in the West and argues that understanding water demand is important, especially when managing scarcity is a goal. Chapter 2 uses aggregate city-level data from four municipalities in New Mexico to investigate seasonal trends and breakpoints. Although per premises and aggregate demand tend to decline in all geographies investigated, existence and timing of breakpoints varies by geography. Additionally, drivers of …

A Socioeconomic Valuation Of Urban Wetland Ecosystems And Policy Recommendation For College Lake, Michael Dunmyer
