Järvi Järveoja

The main goal of my current research is to improve our understanding on how rewetting affects the biogeochemistry and greenhouse gas dynamics of drained peatland forests in the boreal region of Sweden. I achieve this by eddy covariance measurements of the ecosystem-scale CO2 and CH4 exchanges combined with detailed estimates of spatial variability from plot-scale greenhouse gas flux (incl. CO2, CH4 and N2O) measurements using chambers. An important part of this research is collaboration with various governmental agencies and forest stakeholders to support the development of sustainable and climate-responsible forest management strategies.

In addition, I am interested in understanding how the individual component fluxes of the peatland C cycle (i.e. gross and net primary production, heterotrophic and autotrophic respiration as well as plant-mediated CH4 transport) respond to their biotic and abiotic drivers. More specifically, my work explores the relationship between vegetation development and the relative contribution of these component fluxes during distinct phenological phases. For this purpose, I use manual and automated chambers for quantifying CO2 and CH4 fluxes, monitor a suit of environmental variables and collect comprehensive vegetation data.
