NTF spatial distribution patterns
At the genus level, Arthrobotrys was regionally distributed and
found in 98.68% of the sampling sites, while Dactylella andDrechslerella were local distributed and found in 7.02% and
7.89% of the sampling sites respectively (Figure 5).
Among the 44 species detected in this study, the 4 widespread species
were found in 83.30%, 56.58%, 47.37% and 41.23% of the sampling
sites. The 31 rare species found in less than 10% of the sampling sites
(range: 0.41-9.21%) (Figure 6).
When the all species were superposed
in the map, NTF was found to be randomly distributed across the entire
study area (mean variance ratio = 1.014, t = 0.153, p = 0.878). When the
widespread species were removed, the cumulative distribution of rare and
non-widely distributed species OFs was non-random and clustered (rare
species: means variance ratio = 1.284, t = 3.022, p = 0.003; non-widely
distributed species: means variance ratio = 1.326, t = 3.471, p
< 0.001). The widespread species masked the non-random
patterns.
