Role of inter-specific ectomycorrhizal fungal diversity for forest ecosystem nutrition

Break neu


In phase 1 of this project (performed by A. Zaviscic 2013 – 2016) the taxonomic diversity of EMF along a phosphorus (P) gradient was described. We plan to investigate the impact of vertical soil P gradients on the stratification of ectomycorrhizal fungal (EMF) communities, their functions with regard to P uptake and host P supply. Preliminary work suggests that carbon (C) allocation may be important for EMF activities. We will therefore conduct a girdling experiment to test the impact of an interrupted C allocation on the EMF communities and P uptake. Further it was shown that constraints on photosynthetic activities imposed by low P availability were relieved by P fertilization. Therefore, we will test the impact of N and P additions on the EMF communities and their functions. First results of real-time imaging showed a strong divergence of EMF taxa for P acquisition and will be continued in the second phase of the project.
