Open AccessEstimating biomass and soil carbon change at the level of forest stands using repeated forest surveys assisted by airborne laser scanner data
Under the growing pressure to implement mitigation actions, the focus of forest management is shifting from a traditional resource centric view to incorporate more forest ecosystem services objectives such as ...

Open AccessA widely-used eddy covariance gap-filling method creates systematic bias in carbon balance estimates
Climate change mitigation requires, besides reductions in greenhouse gas emissions, actions to increase carbon sinks in terrestrial ecosystems. A key measurement method for quantifying such sinks and calibrati...

Open AccessMycelium chemistry differs markedly between ectomycorrhizal and arbuscular mycorrhizal fungi
The chemical quality of soil carbon (C) inputs is a major factor controlling litter decomposition and soil C dynamics. Mycorrhizal fungi constitute one of the dominant pools of soil microbial C, while their li...

Open AccessBridging map** and simulation modelling in the ecosystem service assessments of boreal forests: effects of bioenergy production on carbon dynamics
Increasing the use of forest harvest residues for bioenergy production reduces greenhouse emissions from the use of fossil fuels. However, it may also reduce carbon stocks and habitats for deadwood dependent s...

Dynamics of soil organic carbon stock in a typical catchment of the Loess Plateau: comparison of model simulations with measurements
Land use changes are known to significantly affect the soil C balance by altering both C inputs and losses. Since the late 1990s, a large area of the Loess Plateau has undergone intensive land use changes duri...

ESLab application to a boreal watershed in southern Finland: preparing for a virtual research environment of ecosystem services
We report on preparatory work to develop a virtual laboratory for ecosystem services, ESLab, and demonstrate its pilot application in southern Finland. The themes included in the pilot are related to biodiver...

Changes in soil carbon stock predicted by a process-based soil carbon model (Yasso07) in the Yanhe watershed of the Loess Plateau
Soil carbon sequestration is an ecosystem process that can provide important ecosystem services such as climate regulation and mitigation of global warming. Spatiotemporal variation in the soil organic carbon ...

Carbon stock changes of forest land in Finland under different levels of wood use and climate change
Prediction of the effect of harvests and climate change (CC) on the changes in carbon stock of forests is necessary both for CC mitigation and adaptation purposes.

Dynamics of Carbon and Nitrogen Fluxes and Pools in Forest Ecosystem
Metabolism of trees, ground vegetation and microbes generate carbon and nitrogen fluxes in forest ecosystems. Carbon flows through the system, and nitrogen circulates between vegetation and soil. Trees synthes...

Increased Carbon Sink in Temperate and Boreal Forests
An intense search is under way to identify the `missing sink' in the world carbon budget of perhaps 2 Pg year−1 (petagrams, or billiontonnes) of carbon, but its location and mechanism have proved elusive. Here we...

Carbon storage in forest soil of Finland. 2. Size and regional pattern
For confidently estimating the amount of carbon stored in boreal forestsoil, better knowledge of smaller regions is needed. In order to estimatethe amount of soil C in forests on mineral soil in Finland, i.e. ...

Carbon storage in forest soil of Finland. 1. Effect of thermoclimate
A total of 30 coniferous forest sites representing two productivityclasses, forest types, were investigated on a temperature gradient(effective temperature sum using +5°C threshold 800–1300degree-days and annual ...

Density of organic carbon in soil at coniferous forest sites in southern Finland
More detailed knowledge of the density of organic carbon in soils of boreal forests is needed for accurate estimates of the size of this C stock. We investigated the effect of vegetation type and associated si...
