The species composition and distribution of NTF in Yunnan
Province
We identified 44 NTF species from 2,250 samples. These species belonged
to three genera: Arthrobotrys (29 species), Dactylella (9
species), and Drechslerella (6 species) (Table S3). The rank
order of occurrence frequency (OF) of NTF species corresponded to a
logarithmic distribution model (R2 = 0.940)
(Figure 3). Four species were widely distributed (mean OF = 5.22%), and
contributed to 9.09% of the total species richness and 62.32% of the
total OF. Conversely, 31 species were classified as rare (mean OF =
0.18%), and contributed to 70.45% of the total species richness and
7.52% of the total OF.
A mean variance ratio of 1.07 (t = 0.7029,p> 0.05) indicated that
NTF species were randomly
distributed (Figure 4).
