Testing assumptions for conservation of migratory shorebirds and coastal managed wetlands Testing assumptions for conservation of migratory shorebirds and coastal managed wetlands
Managed wetlands provide critical foraging and roosting habitats for shorebirds during migration; therefore, ensuring their availability is a priority action in shorebird conservation plans. Contemporary shorebird conservation plans rely on a number of assumptions about shorebird prey resources and migratory behavior to determine stopover habitat requirements. For example, the US...

Climate change and water resources in a tropical island system: Propagation of uncertainty from statistically downscaled climate models to hydrologic models Climate change and water resources in a tropical island system: Propagation of uncertainty from statistically downscaled climate models to hydrologic models
Many tropical islands have limited water resources with historically increasing demand, all potentially affected by a changing climate. The effects of climate change on island hydrology are difficult to model due to steep local precipitation gradients and sparse data. This work uses 10 statistically downscaled general circulation models (GCMs) under two greenhouse gas emission scenarios...

Linking state-and-transition simulation and timber supply models for forest biomass production scenarios Linking state-and-transition simulation and timber supply models for forest biomass production scenarios
We linked state-and-transition simulation models (STSMs) with an economics-based timber supply model to examine landscape dynamics in North Carolina through 2050 for three scenarios of forest biomass production. Forest biomass could be an important source of renewable energy in the future, but there is currently much uncertainty about how biomass production would impact landscapes. In...

Modeling climate change, urbanization, and fire effects on Pinus palustris ecosystems of the southeastern U.S. Modeling climate change, urbanization, and fire effects on Pinus palustris ecosystems of the southeastern U.S.
Managing ecosystems for resilience and sustainability requires understanding how they will respond to future anthropogenic drivers such as climate change and urbanization. In fire-dependent ecosystems, predicting this response requires a focus on how these drivers will impact fire regimes. Here, we use scenarios of climate change, urbanization and management to simulate the future...

Elk habitat suitability map for North Carolina Elk habitat suitability map for North Carolina
Although eastern elk (Cervus elaphus canadensis) were extirpated from the eastern United States in the 19th century, they were successfully reintroduced in the North Carolina portion of the Great Smoky Mountains National Park in the early 2000s. The North Carolina Wildlife Resources Commission (NCWRC) is evaluating the prospect of reintroducing the species in other locations in the state...

The effects of changing land cover on streamflow simulation in Puerto Rico The effects of changing land cover on streamflow simulation in Puerto Rico
This study quantitatively explores whether land cover changes have a substantive impact on simulated streamflow within the tropical island setting of Puerto Rico. The Precipitation Runoff Modeling System (PRMS) was used to compare streamflow simulations based on five static parameterizations of land cover with those based on dynamically varying parameters derived from four land cover...
