Abstract

Decomposition of coarse woody debris (CWD) is an important component of the carbon cycle and biodiversity of forest ecosystems. Dynamics of organic chemicals, nutrients and occurrence of fungi during CWD decomposition have been studied intensively in coniferous boreal forests. However, little attention has been paid to the CWD of angiosperms that dominate temperate areas and to the relation between the organic chemical dynamics and fungal succession during CWD decomposition. Thus, the purpose of the present study is to clarify the mechanism of fungal decomposition of CWD of an angiosperm tree, Japanese beech (Fagus crenata Blume). First, the dynamics of the physicochemical properties of beech CWD during decomposition were estimated. A chronosequence method with a five decay class system was used to estimates the decay process of CWD. Second, a mycological survey was conducted for macrofungi fruiting on CWD and microfungi isolated from CWD, and the relationships between fungal succession and physicochemical changes during CWD decomposition were detected. In light of the results, fungal decomposition of beech CWD and the implication for soil humus accumulation were discussed.
