MiCryoFun – Microorganisms in Arctic cryoturbated soils
On 2. March 2018 by JoergMicroorganisms in Arctic Cryoturbated soils could be main drivers of organic matter transformations of up to 1300 Gigatons of carbon that are currently stored in Arctic permafrost soils.
Arctic permafrost soils are estimated to store 1300 Gigatons (gt) of carbon, an amount half of soil organic C. Substantial amount of this C (600 Gt) is stored in the form of buried organic matter (OM) through the process of cryoturbation. Arctic is warming rapidly and this C can be released to the atmosphere as CO2 and CH4 as a result of increased decomposition. Detailed knowledge on the biotic and abiotic drivers of buried C vulnerability to decomposition is still limited. Particularly limited is the knowledge about functioning of mic. communities in cryoturbated OM, which is the major gap in understanding the decomposition processes and potential GHG emissions from these soils.
The international team of the MiCryoFun project, lead by Jiri Barta from the University of South Bohemia and Tim Urich, University of Greifswald aims to identify circumpolar characeristics of microbial communities and to describe main taxonomical and functial groups responsible for transfromation of organic matter in cryoturbated OM.

Very excited that our Perspectives paper is now available @SoilBiolBiochem! https://doi.org/10.1016/j.soilbio.2021.108357 Amplicon sequencing is routinely used in soil ecological research. However, soil-specific challenges and the nature of amplicon data present obstacles for ecological interpretation
