Figure 2: Principal Components Analysis ordination of the studied grassland vegetation communities gathered in groups (indicated in the panel) described by fuzzy-weighted species composition based on functional relatedness among species. Post hoc correlations of PCA axes with traits are shown in gray. Arrows indicate community-weighted means for the traits based on their correlations with the ordination axes. The numbers refer to the sites (1 – São Gabriel, 2 – Quaraí, 3 – Soledade, 4 – Lavras do Sul, 5 – Santo Antônio das Missões, 6 – Santana da Boa Vista, 7 – Tavares, 8 – Jaguarão, 9 – Vacaria, 10 – Alegrete, 11 – Painel, 12 – Palmas, see Fig. 1 for site location) and are repeated nine times each, indicating plots belonging to the same grid. Colors represent groups of functional relatedness, as indicated by the key on the top right.
