Acknowledgment
We would like to acknowledge bioinformatic help from Dr. D. Scofield , Dr. T.Ammunet, and help with sampling from S. Johannesson and M. Vass. Dr J. TÃ¥ngrot assisted us in raw data and OTU sequence submission as part of the Biodiversity Atlas Sweden which is made possible by its partners and by grants from the Swedish Research Council. In addition to funding from ERC (678792) we acknowledge support for sequencing at the National Genomics Infrastructure (NGI) / Uppsala Genome Center and SciLife Laboratory, Uppsala, supported by the VR and the KAW. Bioinformatic analysis was possible thanks to the National Bioinformatics Infrastructure Sweden (NBIS) and enabled by resources provided by the Swedish National Infrastructure for Computing (SNIC), partially funded by the Swedish Research Council through grant agreement no. 2018-05973.
