BIOGEOMON 2009 Conference Themes
(Including confirmed chairpersons)
1. Integrated monitoring and modelling
Chaired by Paul Whitehead (University of Reading, UK) and co-chaired by Jack Cosby (University of Virginia, USA).
In this session results from modelling and monitoring on the catchment/landscape-scale are presented. A particular aim is to present studies integrating long-term monitoring and modelling data on element fluxes and mass balances.
Keywords: catchment studies, landscape, mass balances, fluxes 2. Forest - atmosphere interactions and exchange: gases and aerosols
Chaired by Michael Boy (University of Helsinki, Finland) and co-chaired by Janne Rinne (University of Helsinki, Finland).
Fluxes and exchange processes of gases and aerosols between forests and the atmosphere are dealt with in this session. Studies quantifying climate-change related processes such as net-ecosystem exchange of C are welcome. Up-scaling of such processes from plot-scale to landscape/regional scales is also an important topic.
Keywords: climate change, upland, vocs, scaling, net ecosystem exchange 3. Hydrological drivers of ecosystem functioning
Chaired by Melanie Vile (University of Villanova, USA) and co-chaired by Leon Lamers (University of Nijmegen, The Netherlands).
In this session studies on the impact of hydrological drivers (e.g. extreme events, droughts, snow melts, storms, and flooding) on ecosystem functioning and processes are presented. Also long-term changes in hydrological drivers (historical, modelled future) are considered.
Keywords: extreme events, droughts, snow melts, storms, flooding, long term trends 4. Linkages between biogeochemical cycles
Chaired by Heleen de Wit (Norwegian Institute of Water Research, Norway) and co-chaired by Ed Rowe (Centre for Ecology and Hydrology, UK)
Linkages between the cycles of different elements (e.g. C and N, N and S, N and P) are dealt with in this session. Also papers dealing with element stoichiometry and redox processes are welcome.
Keywords: nutrient cycling, carbon, nitrogen, sulphur, stoichiometria, redox processes 5. New insights into nitrogen cycling
Chaired by Christine Goodale (Cornell University, USA) and co-chaired by Bridget Emmett (Centre for Ecology & Hydrology, Bangor, Wales)
Studies dealing with new findings regarding N-processes and cycling (e.g. N-fixation, denitrification) or new measurement techniques for N (anammox, dnra) are the focus of this session. Papers quantifying the importance of DON are also welcome.
Keywords: anammox, dnra, DON, denitrification, nitrogen fixation, nitrogen sinks, nitrogen limitation, nitrogen-carbon interactions 6. Biogeochemistry of peatlands
Chaired by Tim Moore (McGill University, Canada) and co-chaired by Raija Laiho (University of Helsinki, Finland).
This session will deal with the biogeochemstry (C,N, cations, and S) of peatlands (mires) and palludified soils. The role of peatland forestry, impacts of fire, and restoration issues will also be included.
Keywords: nitrogen, cations, sulphur, restoration, carbon, peatland forestry, fires 7. Carbon cycling in upland (well drained) soils
Chaired by Egbert Matzner (University of Bayreuth, Germany) and co-chaired by Kate Lajtha (Oregon State University, USA).
Carbon pools, fluxes, related processes and long term trends will be covered in this session. Session 7 includes empirical, experimental and modelling approaches to: DOC dynamics, soil respiration, C inputs to soils, decomposition of below and aboveground litter and C sequestration.
Keywords: DOC, soil respiration, litter decomposition, C pools, C sequestration, long term trends 8. Experimental manipulations of ecosystems
Chaired by Claus Beier (Risø National Laboratory, Denmark) and co-chaired by Filip Moldan (Swedish Environmental Research Institute, Sweden)
Studies based on various types of manipulation experiments (transplants, roofs, water level manipulations, chambers, soil amendments, drainage, liming, fertilizing, etc) and ecosystem restoration will be dealt with in this session.
Keywords: transplants, liming experiments, roofs, fertilizing, soil amendments, drainages, water level manipulations, chambers, restaurations 9. Trace element biogeochemistry and ecosystem impact
Chaired by Tiina Nieminen (Finnish Forest Research Institute, Finland) and co-chaired by Ping Lu (EWL Sciences Pty Ltd, Australia).
Studies specifically dealing with the biogeochemistry of trace elements including both deficiency and toxicity issues will be presented in this session. Presentations on accumulation, availability and fate of elements, as well as on their impacts on soil processes and soil-plant interactions are welcomed.
Keywords: heavy metals, metalloids, micronutrients, REE, Al, toxicity 10. Microbial/rhizosphere dynamics
Chaired by Heljä-Sisko Helmisaari (Finnish Forest Research Institute, Finland) and co-chaired by Krista Lõhmus (Tartu University, Estonia).
The role of microbes, root exudates, fine root dynamics and mycorrhiza in soil biogeochemistry will be dealt with in this session, including molecular approaches, PLFA and rhizotron studies.
Keywords: root exudates, fine root dynamics, mycorrhiza, molecular approaches, rhizotrons 11. Innovative uses of isotopes and tracers
Chaired by Martin Novak (Czech Geological Survey, Czech Republic) and co-chaired by Bernhard Mayer (University of Calgary, Canada).
In this session, results of studies using isotopes and tracers to enhance our understanding of ecosystem processes and pathways will be covered.
Keywords: non-traditional isotopes, light isotopes, N-tracers, radiotracers, cosmogenic isotopes 12. Bioenergy production impacts on biogeochemistry
Chaired by Andrew M. Gordon (University of Guelph, Canada) and co-chaired by Göran Berndes (Chalmers University of Technology, Sweden).
Biogeochemical aspects (e.g. nutrient losses, leaching of DOC and nutrients) of intensive biomass harvesting for use as bioenergy will be covered in this session. Short crop rotation, whole tree harvesting, and logging residue studies will be welcome.
Keywords: short crop rotation, whole tree harvesting, nutrient pools, heavy metal pools, carbon 13. Archives of past environmental change
Chaired by Richard Bindler (Umeå University, Sweden) and co-chaired by Harald Biester (Technical University Braunschweig, Germany).
Studies concerning the use of peat cores, lake sediments, ice cores and other archives (e.g. pollen, tree rings) of environmental change are the focus of this session.
