A mechanism\nthat could explain why the relationship between biodiversity and ecosystem\nfunctioning (BEF) often becomes stronger over time is the co-adaptation developing\nbetween plants and arbuscular mycorrhizal fungi (AMF). AMF live in symbiosis\nwith roots of the vast majority of today\u2019s plant species, mobilizing and\ntransferring mineral nutrients from the soil in exchange with carbon from the\nplants. Nevertheless, the short- and long-term responses of AMF diversity and\ncommunity assembly to plant diversity are as unclear as the role of these\nresponses in BEF. AMF specialists contribute to partitioning of resources among\nplant communities. On the other hand, by forming common mycelial networks,\ngeneralist AMF can facilitate resource sharing. Both effects could contribute\nto the increase of the BEF relationship over time. <\/p>\n\n\n\n

Our subproject explores (1) whether ecosystem aging corresponds to co-adaptation between the AMF and plant partners; (2) how this co-adaptation affects AMF specialization and the strength of the symbiotic link; (3) whether the contribution of AM symbioses to the BEF relationship is contingent on soil history, plant history, or both; (4) whether the observed dynamics are specific to AMF within the soil fungal community and its further functional groups. Using molecular methods, we will assess the community structure of AMF in bulk soils and compare it to other fungal communities. In addition, symbiotic community structure, specialization of AMF and mycorrhization intensity will be determined using rhizosphere and roots of resident plant species, both in the Field Experiment and the Ecotron Experiment.<\/p>\n","protected":false},"excerpt":{"rendered":"
