Ericaceous plant–fungus network in a harsh alpine–subalpine environment
Abstract In terrestrial ecosystems, plant species and diverse root‐associated fungi form complex networks of host–symbiont associations. Recent studies have revealed that structures of those below‐ground plant–fungus networks differ between arbuscular mycorrhizal and ectomycorrhizal symbioses. Nonet...

Tateyama, central Japan.

The ericaceous plant–fungus network was characterized by high symbiont/host preferences. Moreover, the network had a characteristic structure called ‘anti‐nestedness’, which has been previously reported in ectomycorrhizal plant–fungus networks.
