The ForHot research consortium:
The project was started as a pilot project in autumn 2011 and as a full-scale research project in spring 2013. It is coordinated by the Agricultural University of Iceland. Other participants come from University of Iceland (UI), Icelandic Forest Research (IFR), University of Akureyri (UA) and Icelandic Institute of Natural History (IINH) and various European univerities and reserach intitutes (see a list below). Altogether the research consortium consists of ca. 19 senior scientists and ca. 15 graduate and post-graduate students. See the page "Participants" for further info.
Memorandum of Understanding:
All formal participants of ForHot have adapted a common Memorandum of Understanding about cooperation, data sharing, publications and co-author issues, etc.. This MoU has been signed by the PI of each university/institute in behalf of his fellow researchers/students.
One scientist from each of the local institutes/universities has a seat in a Local Coordinating Group:
1) Prof. Bjarni D. Sigurdsson, forest ecophysiologist at AUI (Coordinator)
His CV is found here:
2) Dr. Bryndis Marteinsdottir, plant ecologist at UI
3) Dr. Edda S. Oddsdottir, soil biologist at IFR
4) M.Sc. Asrun Elmarsdottir, plant ecologist at IINH
5) M.Sc. Ulfur Oskarsson, biologist at AUI
6) Dr. Brynhildur Bjarnadottir, forest ecologist at AU
The Local Coordinating Group has then made bilateral agreements with all international participants on how to cooperate within the framework of ForHot and both parties have signed a MoU.

Policy regarding new ForHot consortium members
The ForHot consortium has an open policy for accepting new participants. Requests should be addressed to the coordinator of ForHot. If the proposed research does not overlap with any ongoing activities the local steering board can accept new participants without further delay. If, however, there are any overlaps in the proposed research with ongoing activities, new participants need to be accepted by the leading participants of the ongoing activity and the Local Coordinating Group.
The ongoing work has mostly been funded directly by the univerisities and the research institutes involved (and the researchers themselfs). Other exteral grants linked with the ForHot consortium are listed here below:
- 2017: EU's Marie Curie Action funded a 1-year post-doctoral fellowship for Sara Mara˝ˇn at UAB in Barcelona, but where she will do her field research at the ForHot sites in Iceland.

The internatonal cooperation within ForHot has mainly come through two research networks, to which ForHot belongs formally:
- 2011-2014: FSC-SINK (Forest Soil Carbon Sink Nordic Network). This is a Nordic research network with the aim of integrate interdisciplinary research dealing with impacts of environmental change on soil organic carbon. It has funded some of the infrastructure at the ForHot sites.

* June 5, 2012. Twelve automated chamber systems measuring soil respiration, air and soil temperature and soil water content were initiated on both forest and grassland temperature gradients.
* May 31, 2012. The ForHot sent today in an application to Rannsˇknasjˇur RannÝs for base funding for running the project in 2013-2015.
* May 28, 2012. Marja Maljanen from Univ. of Eastern Finland came and spent a week measuring CH4 and N2O fluxes at both the ForHot study sites.
* May 24, 2012. Hňkan Wallander, Magnus Ellstr÷m, Firoz Shah and Stephanie Reischke came from the Microbial Ecology group at Lund University, Sweden, and spent some days taking samples for DNA analysis of soil bacteria and fungi, as well as installing mesh-bags with C4-plant material for isotopic study to estimate ectomycorrhizal production in the soil. They came through the FSC-Sink Nordic Network.
* May 16, 2012. ForHot got a infrastructure funding from Icel. Res. Council today. This will enable us to start more measurements at both sites.
* May 10, 2012. James T. Weedon from VU Univ. Amsterdam is now working at the ForHot sites. He got funding from ESF for staying with us for two weeks. He is taking soil samples from both study sites to study the community composition of soil microbes, using pyrosequencing techniques.
