Succession of microfungi during Pistacia lentiscus litter decomposition in a Sardinian Mediterranean maquis.

摘要

Changes in the microfungal community developing on Pistacia lentiscus L. leaf litter were monitored from February 2001 (senescent leaves) to December 2002 using litter bags. The Principal component analysis of the 16 samples showed a microfungal succession related to the progressive decomposition of the substratum. The Correspondence analysis of fungal colonizers with Rf>10 revealed three main groups succeeding during the study period. The co-occurrence relationships (on the same leaf) among the major colonizers were analysed. The specialized saprotrophs on P. lentiscus litter: Asterostomella sp. 1 and Endophragmiella boewei were identified as principal colonizers in the mature community..
