The advantages of the CCA-based approach are manifold i) As illustrated earlier, the CCA ordination axes are explicitly linked to environmental gradients, while it is not always the case for CA ... axes can be directly ecologically interpreted as a or as a A usual way for assessing the quality of CA is , CA,k compute, λ the eigenvalue associated to the kth ordination axis: λ...
