Description:
Abstract: 
Our general approach to investigating the response of freshwater wetlands to climatic and land use change is based on tools and products of four previous EPA-STAR grants, and involves the following series of activities:

    Develop scenarios of climate and land cover change, operating on a scale of decades, relevant to the Susquehanna River Basin (SRB).
    Using these scenarios, in conjunction with a coupled surface-ground water model, develop a number of predictive hydrologic scenarios for a collection of 11-digit HUC watersheds representing a range of human-associated land uses in the SRB.
    Characterize the relationships between hydrologic and landcover parameters and ecosystem characteristics and services in wetlands of various types in the SRB, focusing on those with preliminary evidence of non-linearity and/or thresholds.
    Utilize the predicted hydrologic scenarios to forecast changes in ecosystem services across the entire Susquehanna River Basin, clearly identifying where and when non-linearities and/or thresholds in response occur, utilizing a series of unique statistical tools to develop a probability surface.
Purpose: 
To characterize nonlinear responses to global climate change in linked aquatic and terrestrial ecosystems through 1. Selection of a linked terrestrial-aquatic ecosystem that provides critical ecosystem services and ecological functions, 2. Characterization of various global change scenarios, incorporating both climate and land cover, and a method of assessing their effect on the identified ecosystem through the primary forcing factor of hydrology (both alone and in conjunction with other human-associated stressors), 3. Identification of potential nonlinear ecological responses (sensu Scheffer et al., 2002) in the selected ecosystem as a result of these changes, and 4. Estimation of the resultant change in ecosystem services on a watershed and Basin-wide scale in the Susquehanna River Basin.
