Abstracts |
To better understand the mechanisms behind maintenance of the extraordinary plant and fungal diversity in tropical mountain forests we applied, for the first time, network theory to investigate the mycobiont–plant communities. We addressed three different mycorrhizal classes, arbuscular mycorrhizae of tropical trees, mycorrhizae of terrestrial and epiphytic Orchidaceae and cavendishioid mycorrhizae among Ericaceae and Sebacinales. We found significant nestedness (NODF) for arbuscular and orchid mycorrhizal networks. In accordance to previous simulations and verifications of species-rich, mutualistic plant–animal networks, we conclude that preferential attachment of new members to already existing links integrates and maintains rare species and stabilizes our species rich assemblages. |
