Les Silicoflagellés du Golfe de Marseille

Les Silicoflagellés du Golfe de Marseille 227 1 1 4 4 A. Travers M. Travers Station Marine d'Endoume Marseille (7e) France Abstract A study of the Silicoflagellates of the Gulf of Marseilles was carried out using water samples collected during three years (1962, 1963 and 1964), at two stations, in 5, 20, 40 and 60 m water depths, respectively. Dictyocha speculum Ehr. was not often seen, whereas D. fibula Ehr. was present all year round. The main forms are D. fibula typica and D. f. var. messanensis (Haeckel) Lemm . The annual cycle of D. fibula , a very constant one, consists of a period of main development during winter and spring, followed by a period of scarcity during summer and autumn. This cycle is very similar to that described by Nival (1965) in Villefranche sur mer. It seems that in Marseilles, as in Villefranche, the development of D. fibula is limited by temperatures over 15 °C. In summer, D. fibula sinks to deeper and colder waters. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Marine Biology Springer Journals
