Abstract | Background/Question/Methods Results/Conclusions We find that root and soil fungal community composition are influenced by the same abiotic conditions at the landscape scale, pH, nitrogen, and salinity; however, at local scale, different factors structured soil and root communities. Locally, soil community assembly was largely influenced by pH, which is consistent with other studies that have found pH to be a strong determinant of local variation in soil microbial composition. However, local root community composition was not influenced by changes in soil acidity, and preliminary results suggested that plant species richness is the main driver of root community composition. This indicates that while soil fungi are vulnerable to abiotic variations in their surrounding environment, the stable chemical environment provided by plant hosts buffers root microbes from environmental stressors to some extent. These results suggest that endosphere communities are more strongly influenced by biotic factors, like plant diversity, compared to the abiotic conditions that drive soil communities on a local scale. |
