Correlation of shape and predation pressure of four lakes of different structural complexity. Results from PLS using size-corrected Mahalanobis distances as first block and predation pressure as second block are shown. P-value is obtained from permutation test against the null hypothesis of independence with 1000 randomization rounds.
