枯木是森林生物的重要栖息地，木材腐朽菌是决定枯木性质的主要因素，影响着栖息在枯木上的生物群落。本文研究了木材分解真菌对腐木上黏菌和黏菌群落的影响。在196根原木上共鉴定出真菌72种，黏菌34种7变种，枝孢菌16种。虽然白色腐烂是边材和心材的主要腐烂类型，但褐色和软腐也很普遍，尤其是边材。此外，白色腐烂和软腐病呈正相关，褐腐与木材pH值呈负相关。排序分析清楚地表明，在日志分解过程中的隐花植物物种的继承，并表现出显着的相关性与pH值，含水量和木材腐烂类型的社区。这些分析表明，真菌木材分解活动强烈影响隐花植物群落的死木材。(C)2014 Elsevier Ltd和英国真菌学会。All rights reserved.
Dead wood is an important habitat for forest organisms, and wood decay fungi are the principal agents determining the dead wood properties that influence the communities of organisms inhabiting dead wood. In this study, we investigated the effects of wood decomposer fungi on the communities of myxomycetes and bryophytes inhabiting decayed logs. On 196 pine logs, 72 species of fungi, 34 species and seven varieties of myxomycetes, and 16 species of bryophytes were identified. Although white rot was the dominant decay type in sapwood and heartwood, brown and soft rots were also prevalent, particularly in sapwood. Moreover, white rot and soft rot were positively and brown rot negatively correlated with wood pH. Ordination analyses clearly showed a succession of cryptogam species during log decomposition and showed significant correlations of communities with the pH, water content, and decay type of wood. These analyses indicate that fungal wood decomposer activities strongly influence the cryptogam communities on dead wood. (C) 2014 Elsevier Ltd and The British Mycological Society.
