Although there are growing attentions on how human activities alter plant communities, little is known about the
consequences of these changes on the shape of species assemblages and biodiversity patterns. Using three vegetation
man-made forest, a
man-made forest, and a natural secondary forest) from mid-
Yunnan,China, we mainly aim at: (1) testing the patterns in plant communities at the level of species and traits and examining the
community assembly rules; (2) revealing the difference between species and functional diversity relationship; (3) understanding
the relationship between soil nutrients and trait dispersion and biodiversity. The results showed that: (1) species co-occurrence
patterns in the
forest and natural secondary forest were non-random when applying the fixed-equiprobable
algorithm. Specific leaf area in the
forest and leaf nitrogen concentration in the
were both over-dispersion through mean Euclidean neighbor distance in trait space. (2) The difference was significant between
the species and functional diversity in man-made and natural forests, but overall a low covariation was found in the
and natural secondary forests. (3) Soil phosphorus content was positively related to the functional diversity in all
plots, suggesting that it may play an important role in patterning functional diversity.
