摘要
Spatially constrained clustering and ordination techniques revealed 6 broad biogeographic zones whose limits vary yearly; spatially unconstrained clustering and ordinationn techniques showed 2 major sets of non-continguous localities, each characterized by a singular biotic structure. Spatial autocorrelation showed a significant relationship between biomass and geographic distance. -from Authors
