  2. Functional Diversity (FD) The diversityoffunctional properties of species in an ecosystem Intro Data & Method Results Conclusions

  3. Why is FD important? • Link species to ecosystemprocesses • Ability to adapt to changingenvironment • Estimateecosystemrobustness Intro Data & Method Results Conclusions

  4. Data requirement • Ecosystem survey fish data • - 2005-2009 • Fish functionaltraitmatrix • - Max length, length at maturity, fecundity, diet, habitat, growth rate…. Intro Data & Method Results Conclusions

  5. Procedure Intro Data & Method Results Conclusions

  6. FD of the Barents Sea fish community 2009 Latitude Longitude Intro Data & Method Results Conclusions

  7. Conclusions • Higher FD in SW, lower FD in E/NE • Reduction in adaptability and therebyrobustnesstowards NE? Intro Data & Method Results Conclusions

  8. Thanks for theattention! Questions?
