Identifying New Invasives In The Face Of Climate Change: A Focus On Sleeper Populations, Ayodelé C. O'Uhuru
Identifying New Invasives In The Face Of Climate Change: A Focus On Sleeper Populations, Ayodelé C. O'Uhuru
Masters Theses
Sleeper populations are established populations of a non-native species whose population growth is limited by one or more abiotic or biotic conditions, such as climate change. While the northeastern US is predicted to be a hotspot for future invasions, identifying potential sleeper populations before they become invasive can inform proactive, climate-smart invasive species management. I focused on 169 introduced species that are established in one or more northeastern states. I used the Environmental Impact Classification for Alien Taxa (EICAT) framework to systematically identify and review the peer-reviewed literature for these candidate species to quantify their negative ecological and socioeconomic impacts. …
Debris Of Progress: A Political Ethnography Of Critical Infrastructure, Ethan Tupelo
Debris Of Progress: A Political Ethnography Of Critical Infrastructure, Ethan Tupelo
Doctoral Dissertations
In this dissertation, I advance a political ethnography of critical infrastructure to better understand terminal capitalism, in which the waste products of commodification and resource depletion are destroying the ecological systems that support life. My object of study is the massive disjuncture between individual knowledge and intention, and these catastrophic collective planetary outcomes. Theoretically, I develop critical infrastructure theory to diagnose these destructive structures. By “infrastructure,” I mean systems of material and discursive flows fundamental to sedentary human organization, connecting local actions with global systems. Such infrastructure is “critical” in three senses: A) denoting the most important forms of infrastructure …
Dynamics Of Water Supply And Demand In The Bandama River Watershed Of Cote D'Ivoire, Sarah Alima Traore
Dynamics Of Water Supply And Demand In The Bandama River Watershed Of Cote D'Ivoire, Sarah Alima Traore
Masters Theses
Water is a fundamental human right supporting life, health, and livelihoods. Yet water-related issues are ranked among the top five global economic risks (WEF, 2020). About two-thirds (4 billion) of the world's population live with severe water scarcity for at least one month, of which about 48% live in both India and China (Mekonnen et al., 2016). In Côte d'Ivoire, the Bandama River, one of the largest in the country, has struggled to meet expected demand, causing recurrent water and electricity shortages. The city of Bouaké in Côte d'Ivoire and neighboring towns experienced a severe water shortage in 2018 with …
Utilizing Climate Change Refugia For Climate Change Adaptation And Management In The Northeast, Sara A. Wisner
Utilizing Climate Change Refugia For Climate Change Adaptation And Management In The Northeast, Sara A. Wisner
Masters Theses
To account for the effects of climate change, management plans in the northeast need to incorporate climate adaptation. Conserving climate change refugia is one adaptation strategy. Climate change refugia are areas buffered by climate change that enable the persistence of valued physical, ecological, and cultural resources; preserving these areas could be a potential adaptation strategy. Using a translational ecology approach where researchers and managers from the National Park Service, US Geological Survey, the University of Massachusetts, and elsewhere worked together, we focused on identifying refugia for tree, herbaceous plant, mammal, and bird species in order to prioritize them for conservation …
Perceptions Of Historical Climate Change And Park Policy: The Impact On The Fremont Cottonwood In Zion National Park, Kathleen Kavarra Corr
Perceptions Of Historical Climate Change And Park Policy: The Impact On The Fremont Cottonwood In Zion National Park, Kathleen Kavarra Corr
Doctoral Dissertations
Despite its “natural” appearance and the Organic Act 1916 mandate for preservation of the natural environment in National Parks, the Virgin River as it flows through Zion National Park’s Zion Canyon was transformed through massive flood control re-engineering projects in the 1930s. The armoring of the river has had significant impacts on riparian vegetation, particularly on the stands of native Fremont Cottonwood trees that once filled the narrow valley. What was the motivation for this massive flood control project carried out in an arid region with less than 15 inches of rain per year? This dissertation explores the motivations which …
Assessment Of The Economic And Ecosystem Service Contributions Of Usda Forest Service Landowner Assistance Programs In The Conterminous United States, Jacqueline S. Dias
Assessment Of The Economic And Ecosystem Service Contributions Of Usda Forest Service Landowner Assistance Programs In The Conterminous United States, Jacqueline S. Dias
Masters Theses
Forests provide immense goods and services to both local and regional communities. The USDA Forest Service’s, State and Private Forestry program administer multiple landowner assistance programs aimed at helping private forest owners while supporting the continued supply of ecosystem services (e.g., timber harvesting, recreation, carbon sequestration and storage). The two landowner assistance programs assessed in this study are the Forest Legacy Program (FLP) and the Forest Stewardship Program (FSP). A majority of the nation’s forests are privately owned, many of which are facing deleterious impacts like wildfires, invasive species, development pressures, and other adverse effects from climate change. The goal …
Fundamental Controls On The Water Cycle In Arid Environments: A Mechanistic Framework For Spatiotemporal Connectivity Between Hydroclimate And Groundwaters In The Dry Andes, Brendan J. Moran
Doctoral Dissertations
There remain many persistent uncertainties regarding fundamental aspects of natural water cycles in arid mountainous regions, the Dry Andes of South America represents one of the most extreme examples of these environments on the Planet. Deep water tables (>100 meters), long groundwater transit times and distances (>100 years, 10-100 kilometers), limited and infrequent rainfall, remote and difficult to access terrain, and complex salar/evaporite hydrogeology common in these environments make reliable monitoring of these hydrological systems particularly difficult. As a result, major gaps remain in our understanding of critical aspects of the water cycle such as recharge and evaporation …
Pride In Our Prides: Mitigating Human-Lion Conflict In The Okavango Delta, Botswana, Eric G. Leflore
Pride In Our Prides: Mitigating Human-Lion Conflict In The Okavango Delta, Botswana, Eric G. Leflore
Doctoral Dissertations
Humans are having marked effects on the natural world, directly contributing to biodiversity declines around the globe. Large carnivores are disproportionately affected as they are wide-ranging, occur in low population densities, and are typically in conflict with humans. Large carnivores are now rare or absent from many ecosystems as their populations have plummeted and human-carnivore conflicts over livestock remain a main contributing factor. The situation is especially acute for the African lion (Panthera leo) as the species is in decline across Africa and has been extirpated from >80% of its historic range. Estimates show the population has decreased …
