Figure 4:

An example of metabolic maps for two herbivorous fishes in the Mediterranean, developed by combining an aerobic scope performance curve with oceanographic data (for details, see Marras et al., 2015a). Thermal habitat suitability (THS) was computed for the whole Mediterranean Sea from the basin-scale model results. (A) Thermal habitat suitability of a native species, salema (Salpa salpa), based on present-day simulation results. (B) Thermal habitat suitability of the salema projected for a future scenario. (C) Thermal habitat suitability of an invasive lessepsien species, the marbled spinefoot (Siganus rivulatus), based on present-day simulation. (D) Thermal habitat suitability of the marbled spinefoot projected for the future scenario. Black dots represent the sites where the fish species have been observed.
