资源简介：
This data file provides two beta-diversity indices, namely Jaccard and Bray-Curtis, computed from successive weed communities growing in 493 arable fields distributed over the whole French national territory. Temporal environmental distances, environmental heterogeneity and temporal distance are also furnished. Weeds were surveyed in two kind of plots, without herbicide application (control, "c") and with herbicide application (sprayed, "s"). Each year, weeds were surveyed twice, at the begining (n1) and at the middle (n2) of the cropping season.
