Questions: 1.What is the conservation status of the sparids? 2. What are the spatial patterns of diversity and where are threatened species concentrated? 3. What are the factors contributing to extinction risk? 4. Future directions Questions: 1.What is the conservation status of the sparids? 2.

Red List Assessment Methodology: Global Marine Species Assessment
7
Global Marine Species Assessment: Laying the foundation for marine conservation Vision: transform global marine conservation capabilities Method: Complete Red List Assessments of 20,000 species of important marine groups Basis: 250,000 known marine metazoans. Vertebrates, habitat forming primary producers, select invertebrates are most important/doable.
