| Abstract: |
| In forest ecosystems, plant communities shape soil
fungal communities through the provisioning of carbon.
Although the variation in forest composition with latitude is
well established, little is known about how soil fungal communities
vary with latitude. We collected soil samples from 17
forests, along a latitudinal transect inwestern China. Forest types
covered included boreal, temperate, subtropical and tropical
forests. We used 454 pyrosequencing techniques to analyze
the soil communities. These data were correlated with abiotic
and biotic variables to determine which factors most strongly
influenced fungal community composition. Our results indicated
that temperature, latitude, and plant diversity most strongly
influence soil fungal community composition. Fungal diversity
patterns were unimodal, with temperate forests (mid latitude)
exhibiting the greatest diversity. Furthermore, these diversity
patterns indicate that fungal diversity was highest in the forest
systems with the lowest tree diversity (temperate forests).
Different forest systems were dominated by different fungal
subgroups, ectomycorrhizal fungi dominated in boreal and temperate
forests; endomycorrhizal fungi dominated in the tropical
rainforests, and non-mycorrhizal fungi were best represented in
subtropical forests. Our results suggest that soil fungal communities
are strongly dependent on vegetation type, with fungal
diversity displaying an inverse relationship to plant diversity. |
