ABSTRACT: A multivariate regression model using observed climate data is used to forecast the climate-induced changes in macrozoobenthos in spring. This is demonstrated by a forecast over 6 yr of biomass, abundance and species number of macrozoobenthos communities in the southern North Sea. The partial linearity between climate and benthic variables, as well as the existence of a phase lag between climate variability during winter time and the response in macrozoobenthos in spring, makes the climate-induced variability in macrozoobenthos predictable. The results indicate that a major part of interannual and interdecadal variability of marine ecosystem, here demonstrated for macrozoobenthos, can be attributed to the physical forcing of winter climate.
