31. Summary of results from each element
- All presentations summarising preliminary results
are being made available on restricted area of
BIOFUSE website - 0.5 1 page summaries requested from each
element leader to be incorporated into progress
report (deliverable due end Jan 2008)
42. Finalise data sets for meta-analyses
- set of databases for meta-analysis for objective
1 is now complete manuscript in advanced state - 21 databases already submitted for meta-analysis
for objectives 2-4 - deadline for submission of databases for
objectives 2-4 is March 2008
53. Finalise details of deployment of complex
experiment
- presentation clarifying details of assemblages to
be made and deployed by each partner available on
restricted area of BIOFUSE website - all will be deployed within next few weeks
(weather permitting) - agreed to sample (a) community structure (b) NPP
community respiration on basis of rate of
change of oxygen concentration in water using
simple chambers on shore and optical oxygen probe - first measurement within 2 months of deployment
last approx 12 months 3-4 month intervals for
sampling of community - If plates remain in place, the experiment may be
extended
64. Agree principles for data management and
archiving
- data to be shared and archived in Marine Data
Archive, run by VLIZ (http//mda.vliz.be) - presentation by Leen Vandepitte available on
restricted area of BIOFUSE website - BIOFUSE folder already exists in the shared
area, subfolders will be created for each element
of biofuse - will be accessible to all BIOFUSE researchers
using MARBEF login password - All will have authority to download datasets in
all subfolders. Ony leaders of writing teams will
have authority to upload or change datasets.
Submitted datasets should only be changed in
consultation with the leader of the writing team.
74. Agree principles for data management and
archiving
- Basis for authorship use of compiled database
of existing data sets - authorship not automatic, need to make some
contribution to the development of the
manuscript opportunities to contribute to be
made for all potential co-authors (as per agreed
schedule). data owner to decide list of
potential co-authors. - Authorship of papers from empirical research done
during BIOFUSE - all contributors have authorship leader of the
element has first refusal of lead authorship - contributors should be restricted to those with
significant role in the work who could discuss
and defend it (generally max of 3 per
institution). Technical assistants should be
listed in the acknowledgements.
84. Agree principles for data management and
archiving
- All BIOFUSE data exclusively available to BIOFUSE
members until end of MARBEF. - Prior to publication of biofuse papers, meta-data
made visible to whole of MARBEF. Potential users
must contact data owners, initially via a
designated contact person. - After BIOFUSE papers published, BIOFUSE-generated
data to be made publicly available. - Pre-existing data sets submitted for
meta-analysis cannot be downloaded without
permission from original owners - Users will be obliged to cite datasets using a
prescribed citation including the Marine Data
Archive web address. - In all cases, data users must acknowledge MARBEF
in accordance with MARBEF policy
94. Agree principles for data management and
archiving
- The agreed principles will be incorporated into a
formal Declaration of Mutual Understanding on
Data Sharing to be drafted by M Cusson L
Vandepitte circulated for agreement of BIOFUSE
community
105. List potential papers and agree on principles
of authorship
For each, decide - lead author - core writing
team - list of groups/co-authors -
timeframe completion, milestones - publishable
units combine or subdivide? key findings -
likely target journals
- Objective 1
- meta-analysis
- sampling programme
- Objectives 2-4
- meta-analysis
- simple experiment
- rocky shore
- seagrass
- sedimentary shore
- comparison of habitats
- complex experiment
- overall integration

later
115. List potential papers and agree on principles
of authorship
- Principles of authorship
- individuals have been nominated to lead analysis
and authorship of each element - those individuals are entitled to first
authorship of paper or papers emerging from that
element, but may appoint different first authors
depending on input - second author will be person with second greatest
input to write up - other co-authors to be listed in alphabetical
order - last author of appropriate papers would generally
be T Crowe or L Benedetti-Cecchi
12- Broad Scale Patterns And Sources Of Variation In
Biodiversity-Ecosystem Functioning Relationships - Chairs Magda Vincx Katja Philippart Tasman
Crowe Steve Hawkins Lisandro Benedetti-Cecchi
Over-extraction of resources, degradation of
coastal and benthic habitats from coastal
development and destructive fishing practices,
pollution and climate change are causing
extensive loss of marine habitats and
biodiversity. These losses can have drastic
impacts on the stability and functioning of
ecosystems with potential for further impacts on
community structure. Although they remain poorly
understood, generalisations about the nature of
these impacts are beginning to emerge.
Characterising variation in biodiversity-ecosystem
functioning (BEF) relationships in the marine
environment will greatly improve our capacity to
assess consequences for marine ecosystems of
threats imposed by humans.This session aims to
identify general patterns and sources of
variation in BEF relationships by focusing on (1)
broad scale comparisons of findings from marine
BEF research, investigating the effect on
ecosystem functioning of changes in organisms
including microbiota, meiofauna and macrobiota
(2) large scale comparisons of the effect of
ecosystem changes (e.g. human disturbance,
climate change, ocean acidification) on the
functional and structural aspects of marine
biodiversity.

document on BIOFUSE website) - R Aspden invited interested parties to become
involved in development of educational video
its translation into additional languages - I Sousa Pinto invited interested parties to
extend the MobiDic programme of school monitoring
programmes
168. Discuss the potential continuation of
different elements of BIOFUSE
17Sampling programmeplanned extension
- Rationale
- further, more extensive test of existing
hypotheses - fulfil strategic requirement for long term data
sets, particularly those replicated at an
international scale - Approach
- retain all sites, sample with random quadrats
only - try to continue to do winter and summer if
impractical, do only summer - indefinite time frame, 10-15 years likely
- Participants
- UCD, UP, Lecce, AAU, CIMAR, AWI-Helgoland, EMI
- MBA / UoP (SJH/RCT) to be approached
- other potential participants could also be
invited to initiate programmes (eg Spain, Greece)
18Any Other Business
- Klemens Brittas Eriksson proposed analysis of
biofuse data
19Appendix
- agreed points regarding sampling programme
- clarification of rationale and analysis of simple
experiment
20Sampling programmefurther analysis
- wait until datasets are complete (ie after the
final sampling event (this winter)) - always use best estimate of total diversity as
the predictor variable - explore alternative response variables , e.g.
measures of variance, aggregate measures (eg
cover, biomass) - partial out characterise influence of seasonal
variation - multivariate analysis
- stability of individual populations versus
diversity of assemblage - functional diversity
21Simple experimentresponse variables
- Structure
- Taxon richness
- Functional richness
- Evenness (on final biomass only (else combines
cover abund)) - Total cover, cover of particular taxa / groups
- Abundance of selected species
- Final biomass
- Community structure bray curtis (mean and
variance, MVDISP) - (Body size of animals (based on final sample))
- Function
- Community respiration, NPP, GPP
- Secondary productivity (?)
- Nutrient fluxes (seagrass)
22Simple experiment
- Hypothesis loss of key species will affect
resistance and resilience of system to
disturbance, i.e. - (a) there will be a greater/lesser difference
between disturbed and undisturbed treatments when
key species absent than when present - (b) difference between disturbed and undisturbed
treatments will take longer/less time to
disappear in absence of key species than in its
presence

25Simple experiment - analysis
- Hypothesis predicts an interaction between the
factors loss of biodiversity and disturbance
(which may also vary among locations) - Therefore needs analysis capable of detecting
interaction - ANOVA (or 2 factor non-parametric equivalent?)
- Permanova (not ANOSIM)
- Initial reporting of results should be reported
in terms of outcome of test of hypothesis
