The Disturbance and Biogeochemistry Research Group from the University of Eastern Finland (UEF) strengthened its collaboration with the Fire Ecology Research Group from the Northeast Forestry University (NEFU, Harbin, China). At the end of September 2024, Adj. Prof. Kajar Köster visited NEFU facilities in Harbin, the Wildland Fire Behavior Research Laboratory near Harbin, and study areas […]
A new paper by Köster et al (2024) gives information regarding surface fires (dominant in Northern Europe), and how surface fires of different severities could affect post-fire soil greenhouse gas emissions. The results of the study show that fire severity, time since fire and post-fire changes in soil temperature were the main factors driving forest floor […]
The 2-year post-doc position deals with disturbance ecology and biogeochemistry of greenhouse gasses. The position will be funded by the four-year project “Climate and air quality impacts of boreal forest fires” (Jane and Aatos Erkko Foundation). We are seeking a highly motivated candidate with experience in working with soil biogeochemical processes and greenhouse gas […]
A new paper by Köster et al., 2024, compared the potential effects of forest fire through post-fire succession on soil carbon dioxide (CO2) emission rates and soil C turnover time in two fire chronosequences, one with underlying permafrost soil and the other without permafrost. The study demonstrates that forest fires have a profound influence on […]
Our consortium (led by Prof. Annele Virtanen) included people from UEF Aerosol Physics Group, UEF Aerosol physics, chemistry and toxicology research unit (ILMARI), UEF Biogeochemistry group and FMI (Kuopio), got the 4-year research grant (Climate and air quality impacts of boreal forest fires (BoFF, total budget 1.2M eur) from Jane and Aatos Erkko Foundation. In […]
Boreal Forest Fire (BoFF 23) campaign will start soon! We will measure greenhouse gas and aerosol particle emissions from surface fire in Northern European boreal forest, and combine the info with the fire and combustion characteristics. We will use the prescribed/restoration fire performed by Metsähallitus in Kiviniemi (Leppävirta). The fire area is part of the […]
In summer of 2022 we started the field measurements in Selkie fire area (6 hectares of forest burned in Eastern Finland in summer of 2021). The area is owned by Snowchange Cooperative, and it will be allowed to develop under natural succession after the forest fire. Intensive field measurements will take place to: assess the […]
Disturbances and biogeochemistry research group focuses on the effects of disturbances on the biogeochemical cycles in boreal and sub-arctic forests, by linking disturbances (fire, wind, ungulates, etc.) and biogeochemical processes. Description of our current and previous projects you can find from here Our previous activities you can also find from our old blog page.
