| Fluctuations in the abundance of developmental stages and adults of the medusa Liriope tetraphylla were monitored from 1966 to 1993 in the bay of Villefranche-sur-Mer, Northwestern Mediterranean Sea. L. tetraphylla exhibited large interannual variations in both mean abundance level and seasonality, Cluster analysis was applied to classify as ''poor'', years with medium to scarce populations evenly distributed the year; as ''normal'', years with a population maximum during autumn as frequently observed in the Mediterranean; and as ''special'', years with strong population maxima localized in spring or summer. The changing jellyfish abundance levels appeared not to be reliably linked to long-term changes in sea water temperature and salinity, even if... |
