  1. Biodiversity pattern interrelations in ecosystem components: a synthesis from the databases compiled during the MarBEF NoE Arvanitidis C, Faulwetter S, Vandepitte L, Appeltans W, Vasileiadou A, Chatzigeorgiou G, Chatzinikolaou E, Vanden Berghe E, et al....… ……… and many other data providers… World Conference on Marine Biodiversity, 26 – 30 September, 2011, Aberdeen, Scotland

  2. Data policy: DMU for data sharing, or how to involve more datasets and expertise • Sine qua non • Custodians want to have formal agreements before willing to share data • Open onlyto people sharing data in MarBEF Theme 1 • Co-authorship is not sufficient • Scientists want to be involved in the creative process of hypothesis generation and testing

  3. MacroBen database: a scientific experiment never attempted so far

  4. MacroBen: first results on a pan-european scale Objective: to test the validity of the proposed systems for the division of the European seas, against pre-determined criteria. MarBEF Theme 1 publication (Theme Section): Marine Ecology Progress Series 382: 221-311

  5. Question:What divisions? • OSPAR (including Mediterranean & Black Seas) • Fredj’s regions • IHO large areas • LMEs • Longhurst’s regions • ICES (including Mediterranean & Black Seas)

  6. Question:What divisions?

  7. Faunal groups used: • Benthos • Benthos relaxed • Polychaetes • Mollusks • Echinoderms • Crustaceans • Sipunculans

  8. Criteria - proximity (multivariate analyses) - randomness (TD funnels) - differentiation (3rd stage MDS)

  9. Results Longhurst’s provinces; benthos nMDS

  10. Results Longhurst’s provinces; Δ+benthos

  11. Results Longhurst’s provinces; Λ+benthos

  12. Results Longhurst’s provinces; Δ+polychaetes

  13. Results Longhurst’s provinces; Λ+polychaetes

  14. Results Polychaeta across systems

  15. Results Faunal groups within Longhurst’s system

  16. Results Performance of the groups: the “biogeographic paradox”

  17. The LargeNet attempt

  18. The LargeNet attempt • Soft macrobethos • Rocky macrobenthos • Soft polychaeta • Meiofauna (MANUELA) • Rocky macrophytes • Rocky Cromista • Phytoplankton • Zooplankton

  19. Meiofauna The MANUELA attempt

  20. The MANUELA attempt Meiofauna

  21. The LargeNet attempt Macrophytes

  22. The LargeNet attempt Macrophytes

  23. The LargeNet attempt Phytoplankton

  24. The LargeNet attempt Phytoplankton

  25. Comparisons...... • Second-stage MDS

  26. Comparisons...... • Are we on the right path? • Do we have BIAS in our datasets? • WHAT bias?

  27. Comparisons...... Can we face it?

  28. The way forward… Virtual Biodiversity Research and Access Network for Taxonomy http://vbrant.eu EMBOS: Development and implementation of a pan-European Marine Biodiversity Observatory System http://www.cost.esf.org/domains_actions/essem/Actions/ES1003
