I´m a post doc with main interests in C and N cycling in boreal forest ecosystems and their relationship with soil microorganisms.

Research

Boreal forests represent some 30 % of the world´s surface covered by forest and are considered to be a major sink for CO2. At the same time, forest growth, and thus also the C sequestration, is often limited by low N availability in boreal region. In the context of climate change mitigation, it is therefore of great importance to understand the interplay of C and N cycles as well as the role forest management plays in the C balance of this biome and globally.

In my research, I´m focusing on two different aspects of forest management and their effects on the C balance of boreal forest ecosystems. In the first project, I´m exploring the effects of a decade-long and intensive N fertilization (100 kg N ha-1 year-1) on C dynamics in young spruce stands at different locations around Sweden. Beside the potential for increased C sequestration in soil and tree biomass, I´m also interested how the fluxes of C to aboveground litter production and belowground to mycorrhizal roots change in response to high N loading. I use mainly soil and tree biomass inventories and litterfall and soil respiration fluxes to address these questions.

With the same methods, in the second project I study the C stocks and fluxes in forest stands of two most common tree species in Sweden, Norway spruce and Scots pine, growing in the same conditions and at the sites considered favourable for Norway spruce. The main goal is to explain the apparently higher tree volume in pine stands and whether it can be accounted for by differences in aboveground litter production, soil CO2 efflux, or soil C stocks. In addition to pure spruce and pine stands at four locations across Sweden, mixed stands at one additional location give us opportunity to study whether mixed stands can give potentially higher yields and how is this then reflected in the C balance of such ecosystems.
