Environmental Factors Influencing Chlorophyll-a Concentrations in Lake Texoma

Environmental Factors Influencing Chlorophyll-a Concentrations in Lake Texoma

Date: December 1998
Creator: Gibbs, Jennifer S. (Jennifer Sokolovic)
Description: An analysis of algal biomass measured by chlorophyll-a concentration in Lake Texoma was performed as a part of a monitoring program to develop baseline environmental data in order to detect the potential effects of engineered changes in chloride concentrations in the reservoir. This portion of the research project focused on two main research objectives. The first objective was evaluating the effect of sampling strategy on the ability to adequately reflect standing crop estimates and trends in algal biomass. Two sampling regimes utilizing replication of three versus ten samples were applied and then analyzed using a minimum detectable difference algorithm to determine the necessary magnitude of replication to represent the variation in the metric. Chlorophyll-a distribution was analyzed for zonation patterns expected in a river-run reservoir to establish the importance of representative sampling of river, transition and main lake zones of the reservoir for management decisions and trophic characterization.

Environmental Imagination: the Constitution and Projection of a Sustainable Ethos

Environmental Imagination: the Constitution and Projection of a Sustainable Ethos

Access: Use of this item is restricted to the UNT Community.
Date: December 2014
Creator: Day, Philip Garrett
Description: This dissertation provides a theoretical analysis and examination of the role of imagination in the formation of an environmental ethos. The majority of ethical theories in environmental thought largely neglect the role that imagination plays in both the relationships that humans form with their environment, and the subsequent role that imagination plays in constituting the way that those relationships are understood ethically. To explore the role of imagination in constituting and subsequently projecting such an ethical way of being, this dissertation selectively analyzes the history of imagination in philosophy, cognitive science, and environmental thought. In addition, this dissertation also explores the role that images play in forming collective responses to environmental disasters, and the further role that imagination plays in overcoming the moral motivation gap.

The Environmental is Political: Exploring the Geography of Environmental Justice

The Environmental is Political: Exploring the Geography of Environmental Justice

Date: August 2010
Creator: Mysak, Mark
Description: The dissertation is a philosophical approach to politicizing place and space, or environments broadly construed, that is motivated by three questions. How can geography be employed to analyze the spatialities of environmental justice? How do spatial concepts inform understandings of environmentalism? And, how can geography help overcome social/political philosophy's redistribution-recognition debate in a way that accounts for the multiscalar dimensions of environmental justice? Accordingly, the dissertation's objective is threefold. First, I develop a critical geography framework that explores the spatialities of environmental injustices as they pertain to economic marginalization across spaces of inequitable distribution, cultural subordination in places of misrecognition, and political exclusion from public places of deliberation and policy. Place and space are relationally constituted by intricate networks of social relations, cultural practices, socioecological flows, and political-economic processes, and I contend that urban and natural environments are best represented as "places-in-space." Second, I argue that spatial frameworks and environmental discourses interlock because conceptualizations of place and space affect how environments are perceived, serve as framing devices to identify environmental issues, and entail different solutions to problems. In the midst of demonstrating how the racialization of place upholds inequitable distributions of pollution burdens, I introduce notions of "social location" and ...

Environmental journalism curriculum as an imperative of democracy: A philosophical exploration.

Environmental journalism curriculum as an imperative of democracy: A philosophical exploration.

Date: August 2007
Creator: Loftis, Randy Lee
Description: Economic retrenchment, social shifts, and technological changes endanger journalism's democratic role. Journalism education faces parallel threats. I review the state of journalism and education, linking the crisis to society's loss of story, framed philosophically by the Dewey-critical theory split over journalism and power. I explore the potential for renewing journalism and education with Carey's ritual model and Postman's restoration of storytelling. I then summarize existing major academic programs and suggest a new interdisciplinary curriculum for environmental journalism, a specialty well suited to experimental, democracy-centered education. The curriculum uses as pedagogy active and conversational learning and reflection. A graduate introductory course is detailed, followed by additional suggested classes that could form the basis of a graduate certificate program or, with further expansion, a graduate degree concentration.

An environmental justice assessment of the light rail expansion in Denton County, Texas.

An environmental justice assessment of the light rail expansion in Denton County, Texas.

Date: August 2007
Creator: Moynihan, Colleen T.
Description: This study analyzes the proposed passenger rail line expansion along US Interstate Highway 35 in Denton County, Texas. A multi-dimensional approach was used to investigate potential environmental justice (EJ) consequences from the expansion of the transportation corridor. This study used empirical and historical evidence to identify and prioritize sites for potential EJ concerns. Citizen participation in the decision making process was also evaluated. The findings of this research suggest that the southeast Denton community has the highest potential for environmental justice concerns. This study concludes by offering suggestions for an effective public participation process. These include the incorporation of a community's local history into an environmental justice assessment, and tailoring the public planning process to the demographics and culture of the residents.

Environmental Modulation of the Onset of Air-breathing of the Siamese Fighting Fish and the Blue Gourami

Environmental Modulation of the Onset of Air-breathing of the Siamese Fighting Fish and the Blue Gourami

Access: Use of this item is restricted to the UNT Community.
Date: December 2015
Creator: Mendez Sanchez, Jose Fernando
Description: This study determined the effect of hypoxia on air-breathing onset and physiological and morphological characters in larvae of the air breathing fishes Trichopodus trichopterus and Betta splendens. Larvae were exposed intermittently (12/12 h daily) to 20, 17, and 14 kPa of PO2 from 1 to 40 days post-fertilization. Survival, onset of air breathing, wet body mass, O2, Pcrit were measured every 5 dpf. Hypoxia advanced by 4 days, and delayed by 9 days, the onset of air breathing in Betta and Trichopodus, respectively. Hypoxia increased larval body length, wet mass, and labyrinth organ respiratory surface of Betta, but did not affect these factors in Trichopodus. Hypoxic exposure increased O2 by 50-100% at each day throughout larval development in Betta, but had no effect on larval Trichopodus. Hypoxia decreased Pcrit in Betta by 37%, but increased Pcrit in Trichopodus by 70%. Larval Betta reared in hypoxia showed a modified heart rate:opercular rate ratio (3:1 to 2:1), but these changes did not occur in Trichopodus. Compared to Betta, the blood of Trichopodus had a higher P50 and much smaller Bohr and Root effects. These interspecific differences are likely due to ecophysiological differences: Betta is a non- obligatory air-breather after 36 dpf with ...

Environmental Philosophy and the Ethics of Terraforming Mars: Adding the Voices of Environmental Justice and Ecofeminism to the Ongoing Debate

Environmental Philosophy and the Ethics of Terraforming Mars: Adding the Voices of Environmental Justice and Ecofeminism to the Ongoing Debate

Date: August 2013
Creator: French, Robert Heath
Description: Questions concerning the ethics of terraforming Mars have received some attention from both philosophers and scientists during recent decades. A variety of theoretical approaches have been supplied by a number of authors, however research pursuant to this thesis has indicated at least two major blindspots in the published literature on the topic. First, a broad category of human considerations involving risks, dangers, and social, political, and economic inequalities that would likely be associated with efforts to terraform Mars have been woefully overlooked in the published literature to date. I attempt to rectify that oversight by employing the interpretive lens of environmental justice to address questions of environmental colonialism, equality in terms of political participation and inclusion in decision making structures, risks associated with technological progressivism, and responses to anthropogenic climate change. Only by including the historically marginalized and politically disenfranchised "voices," of both humans and nonhumans, can any future plan to terraform Mars be deemed ethical, moral or just according to the framework provided by environmental justice. Furthermore, broader political inclusion of this sort conforms to what ecofeminist author Val Plumwood calls the "intentional recognition stance" and provides an avenue through which globally societies can include nonanthropocentric considerations in decision ...
