Table 2. Selected models using wavelet-revised model regression for spatial changes in demersal fish biomass at the grid cell level. The models are tested with all five predictor variables from the original SEM. Mean trophic level is not shown as it is not part of the best candidate model in any of the time periods. Temperature = T , fishing exploitation = ER , zooplankton production = Zflux and detrital bottom flux = Dflux .
