Figure 3. Partial effect of temperature (a), fishing exploitation rate (b), mean trophic level (c) and zooplankton production (d) on demersal fish biomass as estimated from the SEM (Figure 2). The plots show the change in demersal fish biomass along the range of each predictor while keeping the other variables fixed at their mean values. The different lines represent different spatial scales and time periods (see legend and Figure S2.4 for each SEM).
