1. Nearshore Biodiversity Cross Projects M. Sayer 2008

2. Nearshore Biodiversity: What can the past reveal about the future? Tom Trott Rafael Riosmena-Rodriguez Glenys Gibson/Anna Redden Angela Mead/Charles Griffiths Nova Mieszkowska/Michael Burrows Main contact: Tom Trott Anne MarboeGerhard Pohle Ann Knowlton

3. Major Hypotheses & Objectives Pan-Atlantic nearshore communities share common changes in diversity through time at multiple taxonomic levels Qualitative and quantitative changes in taxonomic groups are similar in Atlantic and Pacific nearshore zones Taxonomic changes are related to disturbance from factors like climate-driven alterations and/or habitat utilization

4. Changing Oceans: The relative importance of multiple drivers L. Benedetti-Cecchi JJ. Cruz K. Iken B. Konar Main contact: L. Benedetti-Cecchi C. Mora HK. Lotze B. Worm

5. Major Hypotheses & Objectives Drivers of biodiversity change operate in interaction Interactions are scale-dependent Small-scale processes contribute to generate large-scale patterns

6. Approach & Analyses Pan-Atlantic data (& metadata) analysis temporal & spatial, trophic levels, taxonomic Global metadata analysis geographical and taxonomic Key Approaches Scope of Analyses
