Growth rates recorded in leaves of P. oceanica at CIMAR and Tabarca in the different sites for control vs. fertilized treatments.
Mean ± SE. **p < 0.01.
Table 1.
Three way ANOVA results for: (a) growth rates; (b) nutrient content (C:N ratio) in leaves; (c) in epiphytes; and (d) consumption rates showing differences due to investigated factors “Location” (fixed and orthogonal factor with 2 level), “Site” (random and nested in “location” with 3 levels) and “Treatment” (fixed and orthogonal factor with 2 levels) considering “plot” as a replicate.
(n = 3 fertilized/control plots per site; 9 fertilized/control plots per location).
