TABLE 1.
An overview on the Sicilian NWFP which show the best performance with respect to four major stress factors, as suggested by the numerical values of the selected EIVs, i.e., T (temperature, range 1–12), U (edaphic humidity, range 1–11), N (nutrients, range 1–9), and S (salinity, range 0–3).
