Abstract

While arbuscular mycorrhizal fungi (AMF) can improve plant growth, nutrition and resistance in both natural and agricultural communities, we lack a fundamental understanding of the local and regional forces that drive community assembly and composition. Here, we take advantage of hierarchical soil sampling across a naturally fragmented plant population and apply a metacommunity approach to pinpoint the role of local factors (i.e. the abiotic soil environment) and regional processes (i.e. dispersal) on the assembly of AMF communities. As we have both root and soil samples, we can directly evaluate four long-standing questions with key relevance for both natural and agricultural settings: i) The importance of dispersal and local environmental conditions (e.g. nutrients) for AMF community structure ii) The importance of the local and regional soil as a source pool for AMF root colonization iii) Spatial variation of AMF fungal communities (i.e. beta diversity) The samples are from two projects: One in the Ă…land Islands, and the other in Zackenberg, northeastern Greenland
