Workshop Report: Biodiversity, Species Composition, and Ecosystem Functioning

This report addresses the following six questions: 1. What is the current biological diversity of the United States? 2. What are the spatiotemporal patterns regulating evolution? 3. How are key ecological and evolutionary processes regulating biodiversity distributed in space and time? 4. How does ecosystem functioning change as biodiversity changes, and how does biodiversity change as ecosystem management changes? 5. How does changing biodiversity and ecosystem functioning affect human services (e.g., clean water, soil for agriculture) provided by ecosystems? 6. What elements are needed to generate modeling capacity for predicting changes in biodiversity and ecosystem functioning and the implications of change to human needs?
