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 (lead by Prof. Annele Virtanen) that 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 […]
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.
New paper by Ribeiro-Kumara et al., 2022, assessed the short- to medium-term effects of fire type on soil C fluxes of mixed jack pine and black spruce forest stands in Canada. Our study shows that both fire types can alter C fluxes in the short to medium term through changes in vegetation and the soil […]
New paper by Orumaa et al. (2022) studied the long-term patterns in species diversity, cover and composition of vascular plants and bryophytes after forest fire and the site-related factors behind them. Research was carried out in northwestern Estonia, using a chronosequence of Scots pine (Pinus sylvestris L.)stands, located on nutrient poor sandy soils, where fires […]
