Compromise analysis of the species assemblage structure in pasture 1: correlation circle showing the ordination of the variables (species) on the factorial plan defined by the first two axes of the PCA on the compromise matrix (a); maps of the factorial coordinates of the 64 sampling points on the first axis of the PCA on the compromise matrix (b) (circles and squares represent positive and negative scores respectively and the size is proportional to the corresponding value).
