Soil Fungal Community in Norway Spruce Forests under Bark Beetle Attack

摘要: Bark beetle infestation is a widespread phenomenon in temperate forests, which are facing significant weather fluctuations accompanying climate change. Fungi play key roles forest ecosystems as symbionts of ectomycorrhizal trees, decomposers, or parasites, but the effect severe disturbances on their communities largely unknown. The responses soil fungal following bark attack were determined using Illumina sequencing samples from 10 microsites mature not attacked by beetle, destroyed and stand where all trees removed after windstorm. proportion ITS2 sequences assigned to mycorrhizal species decreased with increased intensity (from 70 15%), whereas saprotrophs 29 77%). Differences (ECM) community was further characterized decrease sequence Elaphomyces sp. Russula an increase Piloderma sp., Wilcoxina Thelephora terrestris. Interestingly, composition ECM one year removing windstorm-damaged similar that forest, despite attributed fungi decreased.
