Soil fungi as link between plant derived carbon and soil food webs (FunLink)
Zusammenfassung der Projektergebnisse
In sum, this subproject gives comprehensive and detailed insights into resource-related fungal community dynamics, their spatio-temporal distribution patterns and community composition including the sub soil and annual cycle. It uncovered key players of AMF and saprobic soil fungi, confirms that the two fungal channels have specific contributions to carbon transfer across distinct food webs and verifies fungal carbon degraders of different detritusphere substrates. The application of NGS in the second phase revealed taxonomically resolved fungal data for all treatments and replicates and thus provides remarkably detailed information for conceptualizing food web models. The results indicated the presence of core mycobiome along the soil depth, which is composed of a range of functional groups, mainly saprotrophs. Nevertheless, results of the second phase also support the influence of plant resources, especially showing new details in relation to presence or absence of a plant C source (plant knockout experiment). This important role of fungi is noteworthy as agriculture soils are traditionally considered as bacteria dominated habitats. Hence, our subproject has contributed to pin point the need to deepen investigations on soil fungi even in agricultural soils and it underline the central role of fungi as decomposers and their significant contribution to carbon flow in arable soils.
