Figure 2:Results of principle coordinate analyses (PCO) for all taxa combined. A) Ordination plot representing the sites (samples) based on the dissimilarities (Bray-Curtis similarity). B) Overlying vectors of the ordination plot above. Vectors present the strength (length) and direction of the Pearson correlation of taxa with the PCO axes. All numbers and letter are explained in table 1 and 2. The colors represent the 3 large strategic groups: competitive (blue), weedy (green) and stress-tolerant (red).
