Arbuscular mycorrhizal fungi (AMF) show wide inter- and intra-specifc variability in symbiotic functioning. Despite
evidence for signifcant consequences of such variability on plant hosts and AMF responses, there is a poor understanding
regarding the efects on soil properties that can serve as soil health indicators (e.g., soil aggregate stability and nutrient leaching). This study evaluated intra- and inter-specifc variability of diferent fungal isolates on two tree species of economic
and environmental interest, Malus prunifolia and Schinus terebinthifolia. Seedlings were either inoculated or not with AMF
inoculum composed of 14 (for M. prunifolia) or 16 (for Schinus terebinthifolia) individual fungal isolates from four species
belonging to diferent families. After six months in a greenhouse, we found intra-specifc and inter-specifc variability among
AMF isolates and species with respect to plant biomass, N and P contents, proportion of macroaggregates, aggregate mean
weight diameter and soil P in the leachate. AMF intra-specifc variability was more evident in symbiosis with S. terebinthifolia compared with M. prunifolia. Cohen?s d Efect Size inference was used and revealed that isolates difered when plant
and soil parameters were considered and that this was host-dependent. The efect of AMF isolates in reducing soil P losses
depended on the host plant and correlated weakly with the abundance of external hyphae. We conclude that intra- and interspecifc variability in AMF can have an impact both on plant parameters and soil health indicators, and this should be taken
into consideration when formulating inocula for agronomic or ecological applications. MenosArbuscular mycorrhizal fungi (AMF) show wide inter- and intra-specifc variability in symbiotic functioning. Despite
