AB  - Arbuscular mycorrhizal fungi (AMF) strongly affect ecosystem functioning. To 
      understand and quantify the mechanisms of this control, knowledge about the 
      relationship between the actual abundance and community composition of AMF in the 
      soil and in plant roots is needed. We collected soil and root samples in a 
      natural dune grassland to test whether, across a plant community, the abundance 
      of AMF in host roots (measured as the total length of roots colonized) is related 
      to soil AMF abundance (using the neutral lipid fatty acids (NLFA) 16:1omega5 as 
      proxy). Next-generation sequencing was used to explore the role of community 
      composition in abundance patterns. We found a strong positive relationship 
      between the total length of roots colonized by AMF and the amount of NLFA 16:1omega5 
      in the soil. We provide the first field-based evidence of proportional biomass 
      allocation between intra-and extraradical AMF mycelium, at ecosystem level. We 
      suggest that this phenomenon is made possible by compensatory colonization 
      strategies of individual fungal species. Finally, our findings open the 
      possibility of using AMF total root colonization as a proxy for soil AMF 
      abundances, aiding further exploration of the AMF impacts on ecosystems 
      functioning.
