Compartmentalized and contrasted response of ectomycorrhizal and soil fungal communities of Scots pine forests along elevation gradients in France and Spain.

摘要: Summary Fungi are principal actors of forest soils implied in many ecosystem services and the mediation tree's responses. Forecasting fungal responses to environmental changes is necessary for maintaining productivity, although our partial understanding how abiotic biotic factors affect communities restricting predictions. We examined Pinus sylvestris along elevation gradients check potential climate change-associated factors. Fungi roots were analysed at a regional scale, by using high-throughput sequencing approach. Overall soil richness increased with pH, whereas it did not vary climate. However, when representative sub-assemblages, i.e. Ascomycetes/Basidiomycetes, families analysed, they differentially answered climatic edaphic variables. This response was dependent on where settled, versus roots, and/or their lifestyle, mycorrhizal or not, suggesting different functional weights within community. Our results revealed highly compartmentalized contrasted soils. The sub-assemblages indicated range possible selective direct indirect (i.e. via host) impacts variations these communities, unknown consequences, that helps under future global change scenarios.
