Fig. 4: Environmental parameters measured in Phyllophora crispa and Posidonia oceanica.

Environmental data consisting of oxygen (O2) concentration (a), light intensity (b), pH (c), temperature (d), chlorophyll a concentration (e) and water movement (estimated via weight loss of clod cards; f) in Phyllophora crispa (purple), Posidonia oceanica (blue) and neighbouring hard-bottom substrate serving as a reference habitat (brown). Horizontal lines within panels a–e display daily mean of respective deployment (with n = 13 for P. crispa, n = 7 for P. oceanica, n = 6 for reference habitat for O2 concentration, pH and chlorophyll a concentration, and with n = 10 for P. crispa, n = 6 in P. oceanica, n = 4 in reference habitat for light intensity and temperature) of respective parameters in each habitat. Note for panel f: different letters above box plots indicate significant differences between habitats (ANOVA and subsequent Tukey HSD test), with n = 9 for P. crispa, n = 4 for P. oceanica, n = 2 for reference habitat.
