The Ecological Resilience Of A Tropical Montane Pine Forest To Droughts, Fire, And Hurricane Disturbance, Daniel Erland Brugger Swann
The Ecological Resilience Of A Tropical Montane Pine Forest To Droughts, Fire, And Hurricane Disturbance, Daniel Erland Brugger Swann
Electronic Theses and Dissertations
Owing to the geographic isolation and unique climatic conditions which occur in tropical montane forests (TMFs), these systems are highly sensitive to changes in both climate and disturbance. Therefore, as ongoing climate change alters disturbance regimes – potentially facilitating multiple disturbance interactions much greater than that of isolated disturbances – TMFs may be shifted to alternate stable states. However, study of TMF resilience is essentially unknown given the lack of long-term studies in these systems. We address the resiliency of the tropical montane pine forests of the Cordillera Central, Dominican Republic using long-term climate records, remeasured vegetation data, and reconstructed …
We All Want To Change The World: How Behavioral Insights Can Help Reduce Carbon Emissions, Thomas C. Gifford
We All Want To Change The World: How Behavioral Insights Can Help Reduce Carbon Emissions, Thomas C. Gifford
Electronic Theses and Dissertations
The world is in the midst of an unprecedented environmental crisis driven primarily by human behavior. As the world has globalized, countries have developed, and standards of living have improved, global pollution has skyrocketed and has resulted in a wide range of environmentally destructive outcomes. All paths to environmentally sustainable development involve a dramatic cut in carbon emissions from current day levels. In this thesis, I explore how the omission of behavioral factors from mainstream neoclassical models has contributed to, and can aid in reducing unsustainably high levels of carbon emissions. Throughout the history of economic thought, classical economists such …
Climate Driven Changes To Malaria Transmission Patterns In Ethiopian Highlands, Amir Said Siraj
Climate Driven Changes To Malaria Transmission Patterns In Ethiopian Highlands, Amir Said Siraj
Electronic Theses and Dissertations
In the highlands of East Africa, the most populated regions in Africa, temperature is assumed to be intimately connected to the patterns of malaria both in time and space. A large section of the Ethiopian population in this region has historically been shielded from the disease mainly due to the altitudes in the highland regions that have remained free of the disease. However, the region has also seen a large part of its population being affected by malaria in epidemic outbreaks that seem to follow climatic anomalies, especially those of inter-annual increases in temperature. This project examines the inter-annual variability …
The Arctic Game, Sarah E. Nuernberger
The Arctic Game, Sarah E. Nuernberger
Electronic Theses and Dissertations
Since outsiders first visited the Arctic, they have believed in man's ability to conquer the region. Today's Arctic conquest is not one of heroic exploration, but rather one of ownership and exploitation. This paper illustrates contestation in the Arctic through the metaphor of a game, with attendant prizes, players, and rules. It focuses on how to prevent the future destruction of the Arctic given the interactions of the Arctic's landscape, prizes, players, and current management frameworks. In the wake of renewed resource exploitation and escalating climate change impacts, the current frameworks and mindsets are inadequate to support the precarious balance …
Colorado's Large Snow Events' Impact On Tree Ring Growth And Dillon Reservoir, Katrina Leona Marzetta
Colorado's Large Snow Events' Impact On Tree Ring Growth And Dillon Reservoir, Katrina Leona Marzetta
Electronic Theses and Dissertations
Meteorological observations from 1894 through 2010 suggest that 17 historically large snow events occurred in the mountains of Colorado within Denver's water supply region. Of these 16 events, 14 can be identified in precipitation sensitive tree ring records as positive climatic pointer years. If these storms were to occur today, they would have the potential to fill reservoirs in Denver Water's supply system, even after years of sustained drought. These "drought busters" have the potential to refill Dillon Reservoir by increasing average yearly inflow up to 146% of the previous year's inflow. Such drought busters can help Denver recover from …
