SP07e Interplay of soil microbial and mycorrhiza fungal diversity with vegetation successional stage, plant diversity levels and phosphorus availability in subtropical forests of China (sp07e soil microbes)
Microorganisms and mycorrhizal fungi rule resource cycling and plant adaptation to soils. Their community and diversity vary with plant diversity, soil properties and erosion, but were scarcely analysed in highly diverse subtropical forests with mixed evergreen and deciduous trees. In the 1st phase of the research unit, SP7 analyzed the biomass of main soil microorganism groups and their diversity by molecular techniques on 12 comparative study plots (CSPs) in a forest national park. While the 1st aspect will be continued in SP13, SP7 will deepen and extend the molecular analyses. Already obtained sequence libraries will serve to implement arrays or T-RFLP used to extend soil microbial diversity studies to all 27 CSPs. Mycorrhizal status will be determined in a pot experiment coordinated by SP12, which combines tree diversity and different inorganic and organic phosphorus sources. Following the random extinction scenario realized in the reforestation Main Experiment high throughput sequencing of rDNA and rRNA will serve to relate soil microbial diversity to community assemblage and diversity levels of trees. In collaboration with SP4, mycorrhizal status of the phytometer tree Machilus thurngii will be determined.
