Summary: Long-term primary succession of mycorrhizal fungi remains poorly understood despite their key role in shaping plant communities. The project focuses on interactions of ectomycorrhizal and arbuscular mycorrhizal fungi in relation to development of vegetation, soil and soil biota during succession on post-mining heaps in a chronosequence of sites 5 to 50 years in age (Sokolov, Czech Republic). Recent molecular tools for describing microbial diversity will be combined with manipulation experimental approaches to explore the mechanisms behind the shifts of mycorrhizal communities in relation to vegetation diversity, humus form changes, microbial community composition and fauna activity in the soil. We assume that mor type of humus, high fungal bacterial ratio and lack of macrofauna will support ectomycorrhizal fungi, while prevalence of bacteria, mull humus and high earthworm activity will support arbuscular mycorrhizal fungi. Obtained information may have potential practical implication for the management of post-mining sites.
