Description
Summary:Mesozooplankton data were collected monthly from 1966 to 1984 in the Northern Baltic Archipelago Sea. Interannual variability of the abundance of different species were related to climate variability using a multivariate regression model. The results suggest that in the Archipelago Sea the interannual variability during spring and summertime of small zooplankton species such as Acartia spp. and Eurytemora affinis is controlled by the climate variability during winter time. No correlations with large scale climate patterns have been detected for the abundance of larger zooplankton, which seems to be controlled by the grazing pressure of herring. A significantly high correlation between the anomalies of recruitment of spring herring and the copepodites of Pseudocalanus minutus elongatus indicates the top-down control for this zooplankton species.
