Fig. 2.

Principal components analysis between traits measured under high N supply and low cutting frequency. The two orthogonal axes explain 36 % and 23 % of the variance, respectively. See details of abbreviations in Table 1. Error bars in species indicate the s.e. for each species along axes 1 and 2 (n = 39).
