Contribution Of Root Respiration To Soil Respiration During Rainy Season In Dry Dipterocarp Forest, Northern Thailand, Punlop Intanil, Anusorn Boonpoke, Montri Sanwangsri, Phongthep Hanpattanakit

Applied Environmental Research

Soil respiration (Rs) plays a key role in regulating the terrestrial carbon cycle. The nature of this role is determined by the different responses of root respiration (Rr) and microbial respiration (Rm) to environmental factors such as precipitation, soil moisture and temperature. Understanding these responses is fundamental to improving our predictions of climate change impacts on carbon cycling processes. In this study, the ratio of root respiration to soil respiration (Rr/Rs) was studied to improve our understanding of soil CO2emissions. The study aimed to improve our knowledge of Rr in relation to rainy season soil environmental factors in a dry …

Stakeholders' Perspectives Of Design Options For A Rooftop Solar Pv Self-Consumption Scheme In Thailand, Kespanerai Kokchang, Sopitsuda Tongsopit, Siripha Junlakarn, Wichsinee Wibulpolprasert, Morrakot Tossabanyad

Applied Environmental Research

Adoption of solar photovoltaic (PV) power generation systems has been accelerating around the world, contributing to the debate about the future of policy and regulation in a high distributed energy resources future. As one of the leaders in solar investment in Southeast Asia, Thailand has recently shifted its policy framework for the support of small scale, distributed solar PV systems from subsidizing power export through feed-in tariff toward a policy that is focused on self-consumption. This paper investigates stakeholder perspectives of the detailed design options for self-consumption schemes for supporting rooftop solar PV installations. The research methodology employed questionnaires and …

The Threats Of Sea Level Rise: An Eco-Geopolitical Visual Analysis, Jorge L. Nowell-Enriquez

Dissertations, Theses, and Capstone Projects

This eco-geopolitical research produces information about the sea level rising, and the analyst explains and projects global effects, and further problems and consequences of the phenomena in a five-minute-long video clip.

The focus is coastlines floods as a consequence of the sea level rising produced by glaciers melting. The floods will affect regions where over a billion persons are living, mainly coastal cities. Therefore, the sea level rising will produce or ease gradual destruction and sudden catastrophes. Moreover, these catastrophes will spur mass migration that might change the lives of a billion persons by 2045.

How The U.S. Supreme Court Deemed The Workers' Compensation Grand Bargain 'Adequate' Without Defining Adequacy, Michael C. Duff

Faculty Articles

During the second and third decades of the twentieth century the U S Supreme Court issued a handful of opinions rejecting 14th Amendment constitutional challenges by employers to implementation of workers' compensation statutes in the United States Unknown to many the statutes were largely the fruit of privatelysponsored investigations principally by the Russell Sage Foundation and the National Association of Manufacturers of European workers' compensation systems during the first decade of the twentieth century Some of those systems had been in existence since the 1870s and 1880s and many employers preferred them to newlyemerging American employer liability statutes that retained …

Physics & Astronomy Faculty Research

The death of massive stars, manifested as gamma-ray bursts and core-collapse supernovae, critically influence how the universe formed and evolves. Despite their fundamental importance, our understanding of these enigmatic objects is severely limited. We have performed a concept study of an Astrophysical Transient Observatory (ATO) that will rapidly facilitate an expansion of our understanding of these objects. ATO combines a very wide-field X-ray telescope, a near-infrared telescope, a multi-mode ultraviolet instrument, and a rapidly slewing spacecraft to realize two primary goals: (1) characterize the highest-redshift massive stars and their environments, and (2) constrain the poorly understood explosion mechanism of massive …

"Kovel’s contributions to a critique of psychiatry, of political theory and of the ruination of the biosphere have been pathfinding, highly revered, and reviewed and debated in highly prestigious journals and publications such as The New York Times. His work with revolutionaries around the globe (including sojourns in Nicaragua during the Sandinista revolution as just one of many examples), and his achievements alongside some of the leading political activists worldwide have secured for Kovel a premier place in the history of the left. But notoriety is not what drives Kovel’s work. What drives Kovel’s work is a relentless struggle for …

A Cross-Cultural Approach To Environmental And Peace Work: Wangari Maathai’S Use Of Mottainai In Kenya, Eddah Mutua, Kikuko Omori

The Journal of Social Encounters

Protecting the environment and nurturing peace are global concerns requiring scholarly attention across and within cultures. This essay proposes that cross-cultural exchange serves as an invaluable approach to the goal of communicating about creating a healthy environment and everyday peace. We examine how Wangari Maathai interpreted the meaning and purpose of Mottainai as a global call to save the environment. Mottainai is an ancient Japanese concept that means “Don’t waste! What a waste!” Of interest to us is establishing Maathai’s motivation to employ the concept of Mottainai as informed by her lived experiences in Kenya. The relevance of Mottainai to …

A significant body of evidence has demonstrated that biodiversity stabilizes ecosystem functioning over time in grassland ecosystems. However, the relative importance of different facets of biodiversity underlying the diversity–stability relationship remains unclear. Here we used data from 39 biodiversity experiments and structural equation modeling to investigate the roles of species richness, phylogenetic diversity, and both the diversity and community-weighted mean of functional traits representing the ‘fast–slow’ leaf economics spectrum in driving the diversity–stability relationship. We found that high species richness and phylogenetic diversity stabilize biomass production via enhanced asynchrony. Contrary to our hypothesis, low phylogenetic diversity also enhances ecosystem stability …

From Religious Freedom To Indigenous Sovereignty: The Case Of Lyng V. Northwest Indian Cemetery Protective Association (1988), Dana Lloyd

Dissertations - ALL

In 1988 the United States Supreme Court declared constitutional the federal government’s development plan in an area (known as the High Country) that was considered central to the religious practice of three local American Indian nations. The Court admitted that “It is undisputed that the Indian respondents’ beliefs are sincere and that the Government’s proposed actions will have severe adverse effects on the practice of their religion.” Nevertheless, because the disputed area was on public land, the Court thought that the government should be allowed to manage its property in any way it saw fit, regardless of the severe adverse …

Amphibians And Reptiles Of United States Department Of Defense Installations, Christopher E. Petersen, Robert E. Lovich, Sarah Stallings

United States Navy: Publications

The U.S. Department of Defense (DoD) occupies approximately 10.1 million ha of land within the U.S. spanning most ecosystems contained therein. To date, no comprehensive agency-wide inventory of amphibian and reptile species has been compiled. We developed an amphibian and reptile species inventory for 415 DoD installations/sites and evaluated species diversity. The amphibian and reptile species confirmed present on DoD sites represent 66% of the total native species documented in the continental U.S. Snakes are the most widespread group found on DoD lands. Of the military services, Army sites have the greatest number of confirmed species, federally listed, state-listed, and …

Environments Past: Nostalgia In Environmental Policy And Governance, Jordan P. Howell, Jennifer L. Kitson, David Clowney

School of Earth & Environment Departmental Research

A variety of factors shape environmental policy & governance (EPG) processes, from perceptions of physical ecology and profit motives to social justice and landscape aesthetics concerns. Many scholars have examined the role of values in EPG, and demonstrated that attempts to incorporate (especially) nonmarket values into EPG are loaded with both practical and conceptual challenges. Nevertheless, it is clear that nonmarket values of all types play a crucial role in shaping EPG outcomes. In this paper, we explore the role of nostalgia as a factor in EPG. We examine literatures on environmental values, governance, and affect in light of their …

Be-10/Be-9 Ratios Reflect Antarctic Ice Sheet Freshwater Discharge During Pliocene Warming, Rachel D. Valletta, Jane K. Willenbring, Sandra Passchier, Chiara Elmi

Department of Earth and Environmental Studies Faculty Scholarship and Creative Works

Along glaciated margins, ratios of meteoric cosmogenic beryllium‐10, ¹⁰Be, normalized to its stable isotope, ⁹Be, reflect an environmental signal, driven ultimately by climatic change. We explore the application of this isotopic pair as a proxy for East Antarctic Ice Sheet dynamics. We analyze ¹⁰Be/⁹Be in middle Pliocene glaciomarine sediments offshore the Wilkes Land Region (Integrated Ocean Drilling Program (IODP) Site U1361A) and examine our new record alongside existing biochemical/geochemical records (Ba/Al, opal %_wt, εNd, and ⁸⁷Sr/⁸⁶Sr). ¹⁰Be/⁹Be ratios reach local maxima during pulsed, mild warming events and …

Invasive-Plant-Removal Frequency—Its Impact On Species Spread And Implications For Further Integration Of Forest-Management Practices, Bernabas Wolde, Pankaj Lal

Department of Earth and Environmental Studies Faculty Scholarship and Creative Works

For a given invasive plant species and control method, effective invasive plant eradication requires regular monitoring and management. While most previous studies characterize invasive plant species, develop appropriate control methods, or prioritize species for management using aggressiveness and other considerations, few study why some forestland owners are less likely than others to regularly remove invasive plant species. Such information is useful in prioritizing and targeting forestland owners who are at greater risk for invasion, with the stands threatening adjacent forestlands. Towards this end, we surveyed 1800 forestland owners in Virginia and Texas. We use data on forestland owners’ socioeconomics and …

Prevalent Transoceanic Fall Migration By A 30-Gram Songbird, The Bobolink, Noah G. Perlut

Environmental Studies Faculty Publications

Three North American passerines are known to perform transoceanic flights during their fall migration, with open-water flights ranging in length from 1,700 to 3,400 km. However, little is known about within-population variation of these flights. From 2013 to 2017, I used geolocators to study variation in the fall migratory track of the Bobolink (Dolichonyx oryzivorus) from a population that bred in agricultural grasslands of Vermont, USA. Thirteen of seventeen birds took transoceanic flights during fall migration, ranging in length from 1,098 to 3,536 km (mean ± SD = 1,969 ± 640); five of these flights were nonstop from …

Reestablishing A Culture Of Water Competency At An Hbcu, Knolan C. Rawlins

International Journal of Aquatic Research and Education

African American children ages 5 – 19 years drown in swimming pools at rates of 5.5 times higher than those of whites (Gilchrist & Parker, 2014). Literature suggested culture is the culprit for this disparity. A fear of water dates to slavery (Pitts, 2007). After slavery was abolished, the memory of drowning remained part of the African American culture. In the twentieth century, the popularity of swimming grew with the increase in public pools. The era of the Jim Crow laws kept African Americans out of public pools (Pitts, 2007). Although the political landscape has shifted since the Jim Crow …
