  abstract = {{H}ome-{F}ield {A}dvantage ({HFA}) defines the way with which a plant litter may decompose faster in the habitat from which it derives (i.e. home) than beneath a different plant community (i.e. away from home). {R}ecent studies, using plurispecific litter and involving several soil biota groups, failed to demonstrate a clear positive {HFA} effect. {T}he interactions between different soil biota groups and different litter types may cause additive effect on decomposition process. {C}oncomitantly, new hypothesis was raised which expects a continuum from positive to negative interactions between transplanted litter and host litter as both litters become increasingly dissimilar in quality, which has been called {S}ubstrate quality {M}atrix quality {I}nteraction ({SMI}). {A}gainst this background, we aimed at testing the influence of both litter quality and soil organisms in determining the {HFA} and the {SMI} hypothesis. {W}e used reciprocal plurispecific transplanting litter along a gradient of litter quality with three successional stages: early ({S}1), medium ({S}2) and late successional stage ({S}3), coupled with litterbags of different mesh size to select different decomposers communities. {F}urthermore, we analyzed litter quality in order to test the {SMI} hypothesis. {O}verall, we did not observe a general {HFA} or {SMI} effect. {I}n micromesh litterbags, only {S}1 litter showed an {HFA} effect (+7%) while in mesomesh litterbags, only {S}2 litter presented an {HFA} effect (+8%). {T}he contribution of each litter quality fraction to the {HFA} index allowed us to show that only highly labile fractions (i.e., solubles and hemicellulose) presented a positive {HFA} index, independently of the mesh size. {I}ndeed, our findings corroborated the {SMI} hypothesis but for labile fraction only. {F}inally, our results highlighted a strong inertia between different soil decomposer groups for the attack of the most recalcitrant biochemical fraction (i.e. lignin) only in late stage, independently of the litter origin.},
