Biodiversity pattern interrelations in ecosystem components: a synthesis from the databases compiled

during the MarBEF NoE

BioDivMed Workshop, 08-09 November, 2011, Marseilles, France

……… 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.
