Appendix B. Environmental variables (salinity, depth and temperature) in control and fertilized plots during the experiment.

FIG. B1. Mean (SE) depth (A), salinity (B), and temperature (C). Dark circles correspond to control plots and grey circles to fertilized plots. Asterisks denote significant differencies between control and fertilized plots obtained with post-hoc Tukey test. Tests results for depth (t test, t = 2.82, v = 5, P = 0.037), salinity (Mann-Whitney-test, U = 12, n1 = 3, n2 = 4, P = 0.057) and temperature (t test, t = 1.571, v = 5, P = 0.177) were carried out on April 20th and prior the experiment start.
