Voices Of Bangladeshi Environmental Youth Leaders: A Narrative Study, Paige Pappianne
Voices Of Bangladeshi Environmental Youth Leaders: A Narrative Study, Paige Pappianne
Antioch University Full-Text Dissertations & Theses
Can environmental youth leaders affect meaningful positive change in the global fight to reign in climate change? While the academic literature contains a vast array of youth leadership materials, there is a gap in the research of the effect environmental youth leadership programs have at the community level, and specifically how these effects can contribute to environmental sustainability of that community, region, or country. This mixed methods qualitative study narrows this gap by employing grounded theory and narrative analysis to determine how five Bangladeshi environmental youth leaders understand their role in influencing their school and communities’ efforts to adapt to …
Home Range, Habitat Use And Thermal Ecology Of The Florida Box Turtle (Terrapene Bauri) On An Anthropogenic Island In Southwestern Florida, Christina Demetrio
Home Range, Habitat Use And Thermal Ecology Of The Florida Box Turtle (Terrapene Bauri) On An Anthropogenic Island In Southwestern Florida, Christina Demetrio
Antioch University Full-Text Dissertations & Theses
Limited information is available on the ecology of Terrapene bauri (Florida Box Turtle) in mangrove ecosystems. Radio-telemetry and iButton data loggers were used to study the home range, habitat use, and thermal ecology of ten Florida Box Turtles on an anthropogenic island in the mangrove-dominated region of southwestern Florida. The effects of weather variables on movement and activity were also examined. Home range analysis using Minimum Convex Polygons (MCP) and Kernel Density Estimates (KDE) determined an average home range size of 0.81 ha (MCP) and 2.32 ha (95% KDE). Box Turtles moved an average distance of 6.3 m per day …
Environmental Policy Assessment In The Ghanaian Gold Mining Industry: Insights From Stakeholders, Francis Tuokuu
Environmental Policy Assessment In The Ghanaian Gold Mining Industry: Insights From Stakeholders, Francis Tuokuu
Antioch University Full-Text Dissertations & Theses
Environmental policy assessment has been recognized by critical stakeholders (e.g., governments, local communities, academics, environmental advocacy groups, and mining companies) as an effective way of identifying and dealing with the myriad of environmental problems confronting humanity, particularly those caused by mining activities. While the gold mining sector has contributed to the economies of countries in Sub-Saharan Africa since the introduction of structural adjustment programs (SAPs) in the 1980s by the Bretton Woods institutions (the World Bank and the International Monetary Fund; IMF), the sector has also contributed to environmental degradation including water pollution, land contaminations, and generally, human health concerns …
A Multi-Scale Analysis Of Jaguar (Panthera Onca) And Puma (Puma Concolor) Habitat Selection And Conservation In The Narrowest Section Of Panama., Kimberly A. Craighead
A Multi-Scale Analysis Of Jaguar (Panthera Onca) And Puma (Puma Concolor) Habitat Selection And Conservation In The Narrowest Section Of Panama., Kimberly A. Craighead
Antioch University Full-Text Dissertations & Theses
Over the past two centuries, large terrestrial carnivores have suffered extreme population declines and range contractions resulting from the synergistic anthropogenic threats of land-use change and indirect effects of climate change. In Panama, rapid land use conversion coupled with climate change is predicted to negatively impact jaguar (Panthera onca) and puma (Puma concolor). This dissertation examined the environmental variables and scales influencing jaguar and puma habitat selection by season (annual, wet, and dry), using multi-scale optimized habitat suitability models and a machine-learning algorithm (Random Forests), in the narrowest section of Panama. The models derived from the data of an intensive …
Habitat Characteristics And Nesting Ecology Of Golden Eagles In Arizona, Michele J. Losee
Habitat Characteristics And Nesting Ecology Of Golden Eagles In Arizona, Michele J. Losee
Antioch University Full-Text Dissertations & Theses
Golden Eagles (Aquila chrysaetos) have a broad range globally and in general are well-studied. However, Arizona’s Golden Eagle population remained essentially unstudied until 2011, when Arizona Game and Fish Department (AZGFD) began nest surveys for cliff nesting Golden Eagles throughout the state. As a result of this data collection, the natural history of Arizona’s Golden Eagles is finally revealing itself. This dissertation outlined a reliable description of their nesting phenology that provides a framework for timing surveys and a baseline to monitor the effects of climate change on Golden Eagles. The mean date for egg-laying was February 14 and pairs …
Alpine Plant Communities Of The White Mountains Of New Hampshire: Aboveground Plant Diversity And Abundance Correlated To Belowground Factors, Timothy Maddalena-Lucey
Alpine Plant Communities Of The White Mountains Of New Hampshire: Aboveground Plant Diversity And Abundance Correlated To Belowground Factors, Timothy Maddalena-Lucey
Antioch University Full-Text Dissertations & Theses
Alpine plant communities are fragile complex systems that may be threatened by climate change. Patterns of climate-driven soil warming are shown to have lasting effects on ecosystem nutrient cycles, alpine plant phenology, and belowground soil biotic activity. There are concerns in the alpine mycorrhizal research community as to how belowground fungal biomass will react to climate-driven soil warming. To address these concerns I asked in this study what are the correlations between belowground factors such as collective ectomycorrhizal (EcM) and ericoid mycorrhizal (ErM) percent colonization, pH, and soil depth to bedrock and aboveground plant diversity and richness. In 2018, on …
Emergence: Developing Worldview In The Environmental Humanities, Rhonda D. Davis
Emergence: Developing Worldview In The Environmental Humanities, Rhonda D. Davis
Antioch University Full-Text Dissertations & Theses
While the environment has long played a role in humanistic expressions and investigations, the need for a more integrated look at the human-environment relationship has become ever more pressing. More than ever, humanities scholars are recognizing their ability to mobilize critical and creative action to address pressing socioeconomic, sociopolitical, and socioenvironmental problems. Teaching and engaging students through interdisciplinary methods, connecting students and communities, developing a sense of agency and responsibility for planetary sustainability has become a visible focus in higher education. My study aimed to understand how an environmental humanities class affects, if at all, the way students construct worldview. …
Following The Seed: Investigating Seed Saving And Network Creation In The Appalachian Region Of Southeastern Ohio, Molly Hicks
Following The Seed: Investigating Seed Saving And Network Creation In The Appalachian Region Of Southeastern Ohio, Molly Hicks
Antioch University Full-Text Dissertations & Theses
Since the beginning of agriculture, seeds have been cultivated, saved, and exchanged by farmers each year to ensure the success of future crops adapted to local environments. Yet, over ninety percent of our diverse vegetable and fruit crop varieties have been lost due to the industrialization and commercialization of seeds. Industrial agriculture has caused a great homogenization of crop varieties, but locally adapted seeds and their seed savers do still exist on the fringe, and across the world. There is a small but growing body of research on agri-food networks in Western and developing countries where advocates are working to …
