Temporal variation of Bistorta vivipara‐associated ectomycorrhizal fungal communities in the High Arctic
Abstract 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 Ar...
