The 6th international Symposium on Ecosytem Behaviour, BIOGEOMON 2009, is held at Helsinki, Finland, in June 29th –July 3rd 2009. BIOGEOMON’s primary goals are to provide a forum for the dissemination and discussion of recent research findings, to explore future directions for biogeochemi-cal research, and to foster interdisciplinary collaboration between researchers of all ages and countries. There were altogether over 400 registrated participants representing 32 different countries, including both internationally renowned scientists and postgraduate students.The meeting was hosted by The Finnish Forest Research Institute (Metla), the University of Helsinki, and the Finnish Environment Institute (SYKE) in association with the Czech Geological Survey (CR), Villanova University (USA), the University of Reading (UK) , the Geological Survey of Finland (GTK), and the Finnish Meteoro-logical Institute (FMI). The information presented by the speakers during the meeting sessions, as well as by the numerous posters is collected into this publication in the form of abstracts. BIOGEOMON’s emphasis is on biogeochemistry as an evolving and integrated discipline, including research at the watershed, landscape and global scales. Beside traditionally emphasized themes, topical issues are raised in each BIOGEOMON symposium. In Helsinki these issues are peatland biogeochemistry, environmental impacts of bioenergy production, atmosphere – forest interactions, and biogeochemistry of trace metals. Keywords

Welcome to BIOGEOMON 2009
Dear Colleagues,
Welcome to BIOGEOMON 2009, the Sixth International Symposium on Ecosystem Behaviour, jointly organ-ized by the University of Helsinki, The Finnish Forest Research Institute, Metla and the Finnish Environment Institute, SYKE in association with the Czech Geological Survey (CR), Villanova University (USA), the University of Reading (UK), the Geological Survey of Finland, GTK, and the Finnish Meteorological Institute, FMI. This BIOGEOMON meeting is the sixth in the series; the previous five were held in Prague in 1987 and 1993, Villanova University in 1997, the University of Reading in 2002, and University of California (Santa Cruz, USA) in 2006. This year we are hosting over 400 participants from 32 countries around the world.
We hope you enjoy the symposium and your visit to Helsinki, the daughter of the Baltic Sea. The venue for BIOGEOMON 2009 is the Porthania Building, in the City Centre Campus of the University of Helsinki. Located in the heart of Helsinki, we hope it provides a wonderful setting for both our scientific and social programmes. Should you have any questions or need of assistance, do not hesitate to ask our staff and visit our information desk located in the lobby of the Porthania Building.
BIOGEOMON’s emphasis is on biogeochemistry as an evolving and integrated discipline, including research at the watershed, landscape and global scales. BIOGEOMON’s primary goals are to provide a forum for the dissemination and discussion of recent research findings, to explore future directions for biogeochemical research, and to foster interdisciplinary collaboration between researchers of all ages and countries. We are pleased to have attracted a large number of both internationally renowned scientists and postgraduate students, and hope this meeting will provide an opportunity to discuss and to meet and make acquaintances. Beside traditionally emphasized themes, topical issues are raised in each BIOGEOMON symposium. In Helsinki these issues are peatland biogeochemistry, environmental impacts of bioenergy production, atmosphere–forest interactions, and biogeochemistry of trace metals.
We would like to take this opportunity to thank the Plenary Speakers, the Session Chairpersons and Co-chairpersons for their tireless efforts in making BIOGEOMON 2009 such a success. We would also like to thank the generous financial support we have received from our sponsors. Finally, we wish you all a most pleasant and enjoyable stay in Helsinki, and hope you have a stimulating and rewarding meeting.

Litter Decomposition in Forest Ecosystems: What controls it? Can we change it?
Cindy E. Prescott
Faculty of Forestry, University of British Columbia, Vancouver, Canada, [email protected]
In the last decade, we have witnessed a tremendous amount of research on the topic of litter decomposition, driven by recognition of the pivotal role that this process plays in carbon fluxes, hence global climate change. Findings from this plethora of research have challenged some of our thinking about the factors that control rates of litter decomposition (or at least the manner in which they influence decay rates), which has important implications for strategies for sequestering additional carbon in forest soils. Perhaps of greater importance in predicting global carbon budgets, many studies have examined the proportion of litter that is transformed to more stable organic matter (rather than being decomposed), the fate of this material, and the factors that determine its rate of decay.
With respect to litter quality, evidence has demonstrated that lignin and nitrogen contents, while useful for predicting relative decay rates of different litter types, do not control rates of decomposition as directly as we had thought. Nitrogen does appear to stimulate early decay of litters (as long as carbon is readily available), but often leads to greater stabilization into humus through a combination of chemical reactions and enzyme inhibition. While the amount of acid-unhydrolyzable residue remaining after proximate analysis is still a useful measurement for predicting litter decay rates, we now recognize that much of this material in not actually lignin, and that lignin per se is not as recalcitrant as formerly thought. Transformations of materials into increasingly recalcitrant compounds through microbial and biochemical reactions appear to play a greater role in determining the amount of stable organic matter produced, rather than initial litter quality. Finally, viewing litter quality through the lens of plant functional traits has provided a refreshing counterpoint to purely chemical indicators, and an effective means of predicting relative rates of decomposition of litters.
The results of a number of cross-biome litter decomposition studies have provided insights into the influ-ences of various climatic and litter quality variables on decay rates, and the scales at which they operate. Meta-analysis of data from hundreds of litterbag studies indicates that the primary influence of climate is temperature, and that it operates largely by determining the plant forms present, which (through “afterlife effects”) determines the decomposability of the litter. The large amount of data on short-term litter decay rates now available should allow us to adequately predict early-stage decomposition rates in most ecosystems without need for additional litterbag studies. Late-stage decay remains an enigma, and we need to better understand the factors that determine how much of litter will enter the slow stage of decay and how fast it will decay thereafter. There is evidence that 20-30% of the initial mass of litter is transformed to humus rather than decomposition in northern forests (and probably in other less favourable conditions), and will remain as surface organic matter for decades or centuries. A critical gap in our understanding of long-term decomposition and stabilization of organic matter is our currently poor understanding the effects of soil fauna. Several recent studies have indicated that soil faunal activities actually make litter more recalcitrant, and contribute to stabilization of organic matter in soil, contrary to earlier thinking about their effects. Finally, new techniques in characterization of humus and soil organic matter are providing much-needed insights into the chemical nature of humus and soil organic matter, the transformations that create it, and its sensitivity to climatic factors.
The implications of these findings for development of strategies such as fertilization, site preparation, assisted migration, and genetic manipulation to manage carbon fluxes from forests will be discussed.

Returning the ability of forests to capture and store carbon: How much and for how long?
Pekka Kauppi
University of Helsinki, Faculty of Biosciences, P.O. Box 56, 00014 University of Helsinki, Finland, [email protected]
The evolution of woody plants has solved the problem of CCS (carbon capture and storage) in an elegant manner. Photosynthesis is the process for “capture”, and the subsequent formation of durable cells provides the “storage”. Chemical engineers of contemporary time cannot yet challenge the “organic CCS” of woody plants in terms of cost-efficiency or sequestration volume. - Research on CCS is a multi-billion industry aiming at reducing fossil emissions of CO2, especially those from coal-fired power plants.
The expansion of woody biomass that is, organic CCS, sequesters approximately 400 million tons CO2 annually from the atmosphere in the European Union. This is five times more than the fossil CO2 emissions of Finland. It has been debated in scientific literature whether such a removal of carbon dioxide is only a temporary phenomenon, a process merely to “buy time” for implementing efficient reductions of fossil CO2 emissions. There are several empirical, theoretical and modelling approaches, which can address this important question.
First, it is important to understand the historical evolution of “organic CCS”, such as the one within the EU. The historical evolution of biomass carbon sink is the main scope of this presentation. Forest transition, a concept introduced by Alexander Mather (1992) and Alan Grainger (1995), is a key to understanding carbon sequestration in forests in the recent past.
Climate change itself appears as a main threat to future evolution of organic CCS. A recent publication presented an alarming message: The critical role of forests as massive “sinks” for absorbing greenhouse gases is “at risk of being lost entirely” to climate change-induced environmental stresses that threaten to damage and even decimate forests worldwide. The report was presented at a session of the United Nations Forum on Forests (UNFF),which took place 20 April-1 May 2009 at the UN Headquarters in New York City.
Given the impact of green house gases on the radiative forcing of the atmosphere, the Planet will either survive or perish. Survival scenario implies an expansion of the global forest biomass; while losses of biomass, in response to a changing climate, would indicate a final tail spin of the biosphere. If the survival scenario becomes reality, massive co-benefits in terms of provisioning, regulating, cultural and supporting services of ecosystems will follow.

The Biogeochemistry of Drought
Joshua Schimel
Dept. Ecology, Evolution and Marine Biology, University of California Santa Barbara, [email protected]
The world is a dry place: roughly 1/3 of the terrestrial land surface has arid, semi-arid, or Mediterranean climates. Climate models also suggest that drought is likely to become more prevalent with climate warming. However, the biogeochemistry of the dry season has usually been studied only implicitly – as “antecedent conditions” that regulate the pulses of biological activity that occur with the following rains. However, rarely have the biogeochemical processes that occur during the dry season been studied explicitly to understand what creates the conditions at the beginning of the wet, “growing season.”
In California, summer can go for 6 months without any rain and temperatures that can exceed 40 °C. We naturally expected, therefore, that the winter growing season would be a season of high microbial biomass and activity but summer was a period of dormancy and mere survival. Native grasses senesce, some shrubs are drought-deciduous, and microbial respiration rates drop to levels of 0.1 to 0.3 g C m-2 d-1 as soils dry to as low as 5% H2O.
Surprisingly, however we observed patterns distinctly at odds with those predictions. Over the summer, microbial biomass increased, net mineralization rates shifted from negative to positive, the N pool shifted from NO3
- to NH4+ domination, nitrification potentials increased, and even denitrification potentials more
than doubled. These surprising results beg an explanation. Why, at a time when activities are lowest and conditions appear worst, does it appear that many groups of organisms are doing best?
In this talk, I will discuss the dynamics that appear to drive dry season processes. I hypothesize that the surprising ecosystem-level summertime dynamics result from two micro-scale phenomena: a) the physiol-ogy of microbial drought survival and b) the hydrological connectivity/disconnectivity of the “microbial landscape.” As soils dry, microbes experience direct physiological stress, increased resource demands to “pay” for stress-acclimation responses, and resource limitation from hydrological disconnections in their environment. For example, at soil matric potentials down to -0.6 MPa, NH4
+ diffusion is a greater limitation on nitrification than is physiological stress. At water potentials of -10 MPa (easily attainable in dry soil), the only available water is in capillaries and water films of <1 µm diameter, creating potentially extreme limitations for resource diffusion and movement. On the other hand, microbes may experience reduced predation pressure because microbial predators also rely on a “connected” landscape for foraging.
