……… and many other data providers…
• Sine qua non Custodians want to have formal agreements before
willing to share data
• Open only to 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
Data policy: DMU for data sharing, or how Data policy: DMU for data sharing, or how
to involve more datasets and expertiseto involve more datasets and expertise
MacroBen database: MacroBen database: a scientific experiment never attempted so fara scientific experiment never attempted so far
MacroBen: first results on a MacroBen: first results on a pan-european scalepan-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
Question:What divisions?
• OSPAR (including Mediterranean & Black Seas)
• Fredj’s regions
• IHO large areas
• LMEs
• Longhurst’s regions
• ICES (including Mediterranean & Black Seas)
Question:What divisions?
Faunal groups used:
• Benthos• Benthos relaxed• Polychaetes• Mollusks• Echinoderms• Crustaceans• Sipunculans
Criteria
- proximity (multivariate analyses)
- randomness (TD funnels)
- differentiation (3rd stage MDS)

Virtual Biodiversity Research and Access Network for Taxonomy (ViBRANT)
(www.vbrant.eu)
Context: to deploy end-to-end e-Infrastructure services and tools, capturing the life cycle of biodiversity research from inception to publication in an open digital environment.
User oriented: an approach, enabling multidisciplinary groups to create their own virtual research communities, supporting biodiversity science.
Ambition: to change the conventional way taxonomy currently functions and to bring it to the forefront of the biodiversity discipline.
