3.5 Effects of climatic and biotic factors on the intra-annual
stability of community biomass
Consistent with simple regression results, SEM revealed that
intra-annual species asynchrony, functional group PR biomass
intra-annual stability and dominant species intra-annual biomass
stability contributed to community intra-annual biomass stability (Fig.
7). Decreased accumulated amount of precipitation between June and
September (P6-9) resulted in lower community
intra-annual biomass stability by reducing species asynchrony.
Consistent with the results of simple regressions (Table 1),
precipitation in July (P7) increased species richness.
Intra-annual biomass stability of functional group PF, which was
negatively correlated with community stability in simple regression
model, was removed from SEM.
