Ectomycorrhizal (ECM) fungi are important for efficient nutrient uptake of several widespread arctic plant species. Knowledge of temporal variation of ECM fungi, and the relationship of these patterns to environmental variables, is essential to understand energy and nutrient cycling in Arctic ecosystems. We sampled roots of Bistorta vivipara ten times over two years; three times during the growing-season (June, July and September) and twice during winter (November and April) of both years. We found 668 ECM OTUs belonging to 25 different ECM lineages, whereof 157 OTUs persisted throughout all sampling time-points. Overall, ECM fungal richness peaked in winter and species belonging to Cortinarius, Serendipita and Sebacina were more frequent in winter than during summer. Structure of ECM fungal communities was primarily affected by spatial factors. However, after accounting for spatial effects, significant seasonal variation was evident revealing correspondence with seasonal changes in environmental conditions. ... : OTU matrix total fungi Abu and PA dataThis file contains all the fungal OTUs recovered, including ECM and non ECM, abundance as well as presence-absence dataOTU matrix ECM fungi Abu and PA dataThis file contains all the ECM fungal OTUs recovered, abundance as well as presence-absence dataEnvironmental data matirx (raw data)This file contains information about raw environmental data associated with each sample.Shared species analysis EstimateSOTU Data for shared analysis performed using EstimateSShared species analysisR script for plotting shared species between sampling monthsGNMDs ordination analysisR script for GNMDS analysis of ECM fungiIllumina sequencing plate1This file contains both forward (t1-UNIS_S1_L001_R1_001.fastq) and reverse (t1-UNIS_S1_L001_R2_001.fastq) Illumina read data and associated barcode mapping files.
