Fig 2.
Abundance of AMF in roots when a preestablished AMF background community is present relative to when AMF are inoculated in the absence of a background AMF community (RIIcommunity). This reflects the ability of AMF to achieve colonization levels in the presence of an AMF community relative to when no interspecific competition is present. The dotted black line indicates the colonization abundance when no background AMF community was present. Error bars indicate the 95% confidence intervals. Lines connecting means highlight the trend between harvests.
