Abstract

Interannual variability (1959-1999) in population biology of calanoid copepods Pseudocalanus elongatus, Temora longicornis and Acartia spp. in the Central Baltic Sea were described for different life-stages. By means of Principal component (PCA) and correlation analyses the association of the stage-specific abundance to salinity and temperature was investigated. P. elongatus dynamics were related to high salinities in spring favouring maturation and reproduction. Additionally low temperatures appear to be favourable for reproduction, whereas intermediate copepodite stages were positively correlated to temperature. T. longicornis and Acartia spp. life-stages were consistently associated to higher temperatures in spring. Furthermore indications exist that T. longicornis maturation and reproductive success in summer is affected by salinity levels similarly to P. elongatus.
