Joint initiatives and common protocols in extreme events

ClimMani
ClimMani integrated WG1-4 workshops on
Joint initiatives and common protocols
in extreme events ecology,
experiments and modelling
Will be held
24-26 March 2015
University of Copenhagen, Copenhagen, Denmark
Many climate change manipulation experiments have been carried out in recent decades. However, several
challenges remain or have emerged, which limit our understanding of ecosystem functioning under future
climate change. These include inadequate representation of biomes, artifacts, incomparable experiments,
poor representation of relevant scenarios, in particular extreme events, lack of research communication
sharing of results and lack of good data for modeling. This Action will develop a network for the
experimental climate change research community bringing experimentalists and modelers together in
order to provide solutions to these recurrent challenges. The Action will organize workshops addressing key
challenges in climate change experiments and modeling, support research exchange, educate young
scientists and facilitate better sharing and access to experimental data. The Action will be organized within
four Working Groups to address: Experimental best practice, Natural climate gradients as experimental
proxies, Data sharing, and Data-model interaction. The Action will provide added value to European climate
change research by linking high level national research groups and projects to a supra-national level and
provide strong links and interactions with the global research community.
Key scientific questions to be addressed at the workshop:




What are the current model weaknesses and how do we best inform models through manipulation
experiments?
How do we optimize the use of experimental plots when creating complex response surfaces?
How do we optimize gradient studies to maximize usability as response surfaces?
How do we more efficiently take advantage of natural droughts in experiments?

How do we achieve a better integration of models and observed data across transects?

Please note that the first day will be devoted to developing already existing manuscript ideas. If you are
going to participate in the Manuscript Activities (MA) on March 24, you are encouraged to contact the lead
author of the MA you are most interested to participate in, which will help them in organizing their
respective MA. We also urge the MA leaders to keep the groups at an efficient number of participants. The
MAs are:
Manuscript Activity 1: Emerging challenges in climate change experiments: making the best use of a
constrained number of experimental units. This paper aims to explore and optimize tradeoffs between
number of plots, number of response levels and number of treatments in relation to statistical power.
Manuscript leader: Klaus S. Larsen (ksl@ign.ku.dk).
Manuscript Activity 2: Opinion paper on meta-analyses. The aim of this paper is to address issues for
experimentalists, synthesizers and modelers with respect to performing reasonable interpretations of
meta-analyses, dealing with caveats, etc. Manuscript leader: Michael Bahn (Michael.Bahn@uibk.ac.at).
Manuscript Activity 3: Experiments by nature – the value of gradient studies. The aim of this paper will
be to review recent learnings from gradient studies and discuss the pros and cons of climate change
experiments by using natural gradients. Manuscript leaders: Marcelo Sternberg (marcelos@tauex.tau.ac.il)
and Thomas Wohlgemuth (wohlgemuth@wsl.ch).
Manuscript Activity 4: Frontiers in coordinated distributed experiments and surveys along gradients. The
aim of this paper is to provide a first overview of newly existing coordinated experiments and surveys
addressing major advances and challenges. It will then focus on the potential in this emerging field of
experimental biogeography in answering a new set of research questions across larger gradients.
Manuscript leaders: Johannes Ransijn (johannes.ransijn@uni-bayreuth.de) and Anke Jentsch
(anke.jentsch@uni-bayreuth.de).
Manuscript Activity 5: Defining ‘short term’ vs ‘long term’ responses of biomass production to climate
change manipulation across different experiments (FACE, warming, drought, fertilization). The aim is to
identify and analyze datasets from multi-year climate change manipulation experiments where biomass
production has been estimated (harvest or pin-point) yearly, and discuss how the ‘short term’ response
differs from the ‘long term’ response. Manuscript leader: Louise Andresen
(Louise.Andresen@bot2.bio.uni-giessen.de).
Manuscript Activity 6: Experiments underestimate ecosystem responses to drought (working hypothesis,
potential title). The aim of this activity is to compare results from studies on natural droughts with results
from experimentally imposed droughts in terms of ecosystem responses (cover, biomass, NPP, mortality).
Manuscript leader: György Kröel-Dulay (kroel-dulay.gyorgy@okologia.mta.hu)

If you are not directly involved in the current Manuscript Activities you can plan you travel for participating
during the second and/or third day(s), which will be devoted to cross-cutting sessions covering six themes:
Session A (WGs 1,2,4): Extreme events - experiments and modelling. This session will focus on drought as
an extreme event. How may new information be gathered in the best way using manipulation and gradient
studies? Current weaknesses in models are explored based on this information. Session leader: Claus
Beier.
Session B (WGs 1,2,3): Combining response surface experiments and natural gradient observations
(including disturbance). The main questions to be addressed are: How do we optimize the use of
experimental plots when creating artificial response surfaces? How do we optimize gradient studies to
maximize usability as response surfaces? How do we more efficiently take advantage of natural droughts
in experiments? Session leader: Klaus S. Larsen.
Session C (WGs 1,2): Developing standardized, reference metrics for ecological experiments. Even when
variables are measured in the same way across experimental sites, local differences in climate, soil and
vegetation complicates cross-site comparison. This calls for developing common metrics that can be used
to quantify differences in, for example, water or nutrient availability between sites, experiments and
treatments. This session aims to describe such metrics, including a prototype ‘phytosensor’ and a plan for
its application across sites during 2015. Other standardized metrics (e.g. the ‘tea-bag’, ‘nutrient sticks’ and
other potential methods) will also be discussed and plans for follow up will be shaped. Session leaders:
Johannes Ransijn and Philipp von Gillhausen for Anke Jentsch.
Session D (WGs 1,2,3): Gathering and developing common protocols. Comparing similar data across
different experiments still poses a major challenge due to lack of common protocols. This session aims to
generate a detailed working plan for how to gather existing protocols from previous network activities as
well as initiate the development of new protocols where needed. Session leader: Hans de Boeck and
Vigdis Vandvik.
Session E (WGs 2,4): Modelling transects. This session will attempt to identify transects where data from
gradient studies could be used by modellers towards a better integration of model and data. Session
leader: Louis Francois.
Session F (WGs1,2): Evidence of carbon limitation in ecosystem research. It became an almost
unquestioned assumption that C is the prime limiting resource in plant life. At least this is the starting
point of most models and why people discuss CO2 fertilization. This session will aim at revisiting this
assumption and discuss situations where this assumption may be valid and where not. Session leader:
Christian Körner.
Each day will start with a morning session of talks serving to set the stage of the discussions during the
cross-cutting sessions. Furthermore, we have allocated time and rooms for other scientific interactions
(smaller meetings and discussions) during both days – if some groups should have the need for this.
All oral presenters: Please prepare 25 minute presentations – leaving 5 minutes for questions.
Please note that we have now added one more theme since the SurveyMonkey where you gave your
preferences with respect to session attendance. We will therefore start in the morning on 25 March with
making the final plan of who attends which sessions – some of you may want to change sessions – and we
may want to push towards having a more balanced number of participants to each session.

How to register – and what will be reimbursed?
You have all accepted the electronic eCOST invitation:
Sender was: "noreply@cost.eu"
Title was: "[COST] Action ES1308 Meeting invitation: ...."
You were then directed to a page where you should enter your travel times and travel costs. You can first
just enter the info you have at hand and press "Save" at the bottom of the page to finish the registration.
Please save the link given in the invitation e-mail where you find it again, because you will have to go
back to this page after the meeting to submit and print-out the final travel claim.
Since this is the last activity of our budget year we need quickly to get information from you about the time
of arrival and departure and cost of your air tickets (or train tickets, etc. to get to the meeting). Please book
those as soon as possible and send the information about travel cost and times by e-mail to the Grant
Holder (grant.holder@lbhi.is).
AFTER THE MEETING you go back to this page and register all your travel costs for your reimbursement
claim, press submit, print it out and send it together with copies of your travel expenses and flight tickets to
the Grant Holder for reimbursement, within 30 days after the meeting has ended.
Regarding the travel reimbursement rules then please note the following:
* Hotel costs will be reimbursed by a flat rate of 120 EUR/night.
*Food costs will be reimbursed by a flat rate of 20 EUR/meal (2 meals = full day). The Local organizer will charge you
directly for the meals that he offers (80 EUR, if you stay for the whole meeting), but you will get that reimbursed after
the meeting from COST, together with the other meals.
* Actual long distance transport costs will be reimbursed, in accordance to the COST rules. But please note restrictions
that apply for e.g. only using the lowest available economy airfares up to a maximum of 1200 EUR. Business class air
tickets will not be reimbursed. The long distance transport can be with plane, train or car. For the first two you need
to submit a copy of the receipt with the travel claim after the meeting, but car travel is reimbursed by 0.2 EUR/km (0.3
EUR/km if more than one participant shares the car; max 2000 km). You then need to submit a GoogleMap figure
showing the route and the distance with the travel claim.
* Participants staying for the whole three-day meeting can at maximum get four hotel nights reimbursed. I.e. it is
allowed to stay one extra day, if participants can show that they can’t arrive in time for a MA or cross-cutting session
they are registered to, or can’t reach their home during the same day as the last such activity ends.
* Local travel costs (usually meaning from home to airport and from airport to/from venue and between venue and
hotel during meeting) is either reimbursed with a flat rate of 25 EUR (then no receipts are needed) or from copies of
actual receipts that are submitted with the travel claim. According to COST rules taxi costs are only reimbursed if flight
arrivals/departures are later than 22:00 or earlier than 7:00, and then only as 80 EUR at maximum.
* The following restriction about travel costs was accepted by the Organizing Committee (Core Group of ClimMani):
 The Grant Holder will request that all participants to send him mail before the meeting with the time of start/end
of travel and TOTAL COST of main travel to and from Copenhagen. The amount given there will be the maximum
amount that will be reimbursed if we will have budget constraints after the meeting.
 Local travel (from/to airport/train station to hotel; from/to hotel to meeting venue in Copenhagen) will only be
refunded by 25 EUR flat rate, if we will have budget constraints after the meeting.
* Further info about COST reimbursement rules can be found at the COST homepage.
