How do existing BES long-term data apply to the three conceptual areas? • Relate to LTER Core Areas: • Primary production • Flow of inorganic matter • Flow of organic matter • Population studies • Disturbance • Satisfy Additional Core Areas for Urban • Human land-cover change and ecosystem effects thereof; • Monitor effects of human-environmental interactions, and develop appropriate social-ecological data and analysis; • Integrate research with local K-12 educational systems.

How does each of the drivers relate to the other two? • How does locational choice affect: • Biotic metacommunity structure and change? • The stream dis/continuum structure and processes? • How does the stream dis/continuum affect: • Biotic metacommunity structure and change? • Locational choices of households and firms? • How does the biotic metacommuinty affect: • The stream dis/continuum structure and processes? • Locational choices of households and firms? • N.B. Direct effects on each other; indirect through spatial heterogeneity.
