A Climate and Operational Vulnerability Assessment of the Water Company in Salamanca, Chile
(2017-04-28)The present master’s project is an analysis of the future vulnerability of the water company (Aguas del Valle) in Salamanca, Chile to potential changes in population, per capita water use, leakage, and climate. Scenario ... -
A Comparison of Aboveground Biomass in Mature Old-Field Forests and Hardwood Forests of the Piedmont Using High Resolution LiDAR Data
(2015-12-07)Airborne scanning LiDAR (Light Detection and Ranging) is a promising technique for efficient and accurate forest volume and biomass mapping due to its capacity for direct measurement of the three-dimensional vegetation structure. ... -
A new context for agroecology: establishing the foundation in the southeastern US considering the implications of climate change
(2018-04-25)Agroecology is grounded in indigenous knowledge. Current agroecological research is primarily focused on Latin America, reflecting an area where substantial indigenous populations actively practice it. This project aimed ... -
A Predictive Thermal Habitat Model for Harbor Seals in the Northwest Atlantic
(2016-08-23)We analyzed projections of current and future ambient temperatures along the eastern United States in relationship to the thermal tolerance of harbor seals in air. Using the earth systems model (HadGEM2-ES) and representative ... -
Adaptation to Climate Change by Smallholder Coffee Producers in Latin America
(2016-04-29)Smallholder coffee farmers in Latin America are already being impacted by and adapting to climate change. Our client, Counter Culture Coffee, a coffee roaster that sources from coffee cooperatives throughout Latin America ... -
Agriculture in a Changing Landscape: Modeling shifts in the geospatial distribution of crops in response to climate change
(2014-04-17)Altered patterns of temperature and precipitation associated with global climate change are expected to affect the productivity of agricultural regions around the world, with varying regional impacts. Since ideal environmental ... -
Allowance Allocation Options under the Clean Power Plan Proposed Mass-Based Model Rule
(2016-04-28)The Clean Power Plan is a major element of the United States’ strategy to combat climate change. The Clean Power Plan addresses carbon emissions from existing power plants by setting emissions limits for each state. Under ... -
An Evaluation of Black Sea Bass (Centropristis striata) Distribution and Habitat Availability in the Northwest Atlantic Ocean under Climate Change
(2021-04-30)Fishery scientists are increasingly concerned about the impacts of climate change on marine fisheries and ecosystem health. Many marine species along the Northeast United States continental shelf have shifted spatial distribution ... -
Applying machine learning to investigate long-term insect-plant interactions preserved on digitized herbarium specimens.
(Applications in plant sciences, 2020-06)Premise:Despite the economic significance of insect damage to plants (i.e., herbivory), long-term data documenting changes in herbivory are limited. Millions of pressed plant specimens are now available online and can be ... -
Assessing the current and future status of aquatic and hydrologic ecosystem services in the French Broad River Basin
(2017-04-28)Ecosystem services are the benefits that people receive from nature, and are an increasingly important component in conservation planning. Many of these ecosystem services are threatened, however, by land use change and ... -
Assessing the Potential Effects of Climate Change on Species in the Cumberland Piedmont Network of the National Park Service
(2012-04-26)In this study, we evaluate the climate change vulnerability of a subset of key species found in the Cumberland Piedmont Network (CUPN) of the National Park Service (NPS), an ecologically important and diverse region. We ... -

Biogeomorphodynamics of Coastal Ecosystems under Conditions of Climate Change and Nutrient Enrichment
(2013)At a given time, tidal landforms inhabit one of three alternate elevation-determined stable states: salt marsh, sub-tidal platform, or tidal flat. The balance between soil production and sea level rise controls transitions ... -
Bridging Hydrology, Ecology, and Reservoir Management to Address Environmental Flow Specifications from Dams in a Changing Climate
(2019-04-26)Water resource management has altered the natural flow regime of rivers around the globe. Buffers to environmental risk and uncertainty, dams balance competing demands for water storage and release for human needs. While ... -
