various. (Haritonidis 1978)
Analyses of part of the marine elements indicate that Atlantic and
Mediterranean species prevail (Feldmann 1938; Haritonidis 1978; Haritonidis et al. 1986). Cosmopolitan species, most of which are found in
great numbers and show maximal growth during the winter months
(Fig. 17.2), are especially interesting because many of them constitute the
so-called eutrophication index (Haritonidis et al. 1986).
