Table 1 Evidence of AM fungi in leaf litter has come from a variety of ecosystems but only seven publications. Data in this table are taken directly from referenced publications unless noted otherwise. Abbreviations are used for elevation (elev.), temperature (temp.), and months (mo.)

From: Revisiting the ‘direct mineral cycling’ hypothesis: arbuscular mycorrhizal fungi colonize leaf litter, but why?
