Basic Questions Addressed by SERAP
What effects will climate changes have on terrestrial andaquatic ecosystems?• What are the likely impacts of future sea level rise on coastal habitats?
• How will stream flow changes alter habitat conditions necessary forhealthy fish and mussel populations?
• Will changes in vegetation and land use affect terrestrial habitats forbird populations?
What can we do to avoid the worst effects of climate change?• What are the causes and degree of uncertainty in forecasts of climate
change and responses?
• What are the benefits and effectiveness of adaptation strategies?

Hydrologic Modeling - PRMS
• PRMS is being used to developcoarse- and fine-scale watershedmodels
• Both coarse and fine scale modelswill incorporate probabilisticdownscaled climate changeprojections to predict daily stream-flow through 2100

Simulating Water Quality –PRMS/SNTEMP
• Stream temperature is beingsimulated using a coupledPRMS/SNTemp model
• SNTemp developed by USFWS andUSGS to predict how changes in flowregime affect water temperature
• Uses PRMS output parameters andphysical channel characteristics
• Daily minimum and maximumtemperatures through 2100 will bepredicted

Ecological Modeling - Fish and musseloccupancy
• Empirical multi-state, multi-season occupancy model.
• Models estimate the occupancy (presence) of fish species in astream segment (defined as a section of stream from tributaryjunction to tributary junction).
• The dynamics of the populations (colonization, reproduction,extinction) are modeled as a function of geomorphic channelcharacteristics, stream size, seasonal discharge statistic, andstream temperature.
• Specific species characteristics (preferred habitat, locomotionmode, body size, spawning duration, etc.) are used in models.

• Basic objective: Test hypotheses aboutavian range dynamics as function ofclimate change and other relevantfactors.
• Probabilities of local extinction andcolonization predicted as function of:
o Climate change
o Land-use change
o Location within overall speciesrange
o Neighbor effects (occupancy ofnearby locations)
• Ranges are likely to shift or contractand can be modeled by varying rates ofextinction/colonization
