Theme 1 Workshop at Crete

Location: Crete
Event Type: Workshop
Event Date: 2005-10-24    
End Date: 2005-10-28

Event Description:
Goal: Analysis of spatial patterns of diversity from soft benthic data collected from MarBEF partners

This workshop is a continuation of the Oslo meeting (OWS) in March 2005. The database from the OWS consists of a large set of quantitative data which ranges from the Arctic to the eastern Mediterranean with all sample sites geo-referenced in a GIS system. The meeting in Oslo was a small workshop with invited specialist to quality control the database and try out initial analyses to check the performance and usability of the database. This workshop in Crete is open to all MarBEF partners to discuss spatial patterns. We are planning to have half of the workshop devoted to analyses of the new database and half to presentations and discussions of spatial patterns of diversity. Analyses of data will be carried out at over large biogeographical areas across Europe with working groups in:

a) Analysis of pattern
b) Modeling
c) Taxonomic distinctness
d) Functional diversity

The overall objective for Theme 1 is to understand how marine biodiversity varies across spatial and temporal scales, and between levels of biological organization in order to develop methods to detect significant change.
To help us reach our goal questions/hypotheses were posed during the Oslo meeting. These are:

1. How do functional characteristics vary in different areas? What are the number of species within different functional groups and how do they vary over European waters?
2. Are there differences between offshore and coastal benthic assemblages in structure and functional processes?
3. What are the relationships between functional traits and productivity?
4. How do major water masses influence benthic diversity? (e.g. Arctic, Mediterranean etc)
5. Are there spatial and temporal correlations in assemblage structure?
6. How are local and regional species pools defined in a European marine context?
7. How do species abundance patterns vary across geographical areas? Species-area relationships in European soft sediment assemblages in relation to scale/extent and in relation to traits (e.g. larval modes).
8. What are the range size estimates for marine species across Europe, (we do not have many for European marine soft sediment species).
9. Is biodiversity of Arctic really lower than at lower latitudes?
10. Are there differences in structure between marine and terrestrial/freshwater systems? (This will need collaboration with terrestrial ecologists).
