Fluctuation in the distribution of the scyphomedusa Pelagia noctiluca (Forskaal) in the Adriatic
An unusual distribution and high population density of Pelagia noctiluca medusae have been noted in the Adriatic from 1977-1981 and some potential explanations of this phenomenon are discussed. This phenomenon has been linked to cyclic fluctuation in Intermediate Levantine water circulation in the Adriatic. Some parallels have been found in the fluctuations in the Mediterranean and North-East Atlantic.
