The effect of forest management intensity on the diversity of wood-decaying fungi and dead wood decomposition – FunWood

Coarse woody debris is a key habitat element in all forest ecosystems and it is mainly decayed by fungi. Within the project we intend to investigate the change in dead wood fungal diversity along a forest management intensity gradient and its correlations with wood decay and ecosystem processes such as nitrogen fixation, gaseous emissions and organic carbon leaching. Most studies on dead wood decomposition have focused on old growth forests, where large amounts of dead wood are available. However, whether the decomposition patterns in dead wood are altered through patterns in fungal colonization which are related to the forest management (intensity, landscape context) has not been investigated so far. Important hypotheses of the project are: The diversity of wood-decaying fungi increases with decreasing forest management intensity. Wood decomposition rates as well as the degree to which wood is completely mineralized increase with fungal diversity. For the studies on fungal diversity traditional methods by the determination of fruitbodies as well as molecular methods are applied. The investigated plots are located within the biodiversity exploratories of the DFG Schwäbische Alb, Hainich, and Schorfheide.
