Berthome, Jean-paul - 1991Le projet de développement d'un réseau instrumenté de surveillance de l'environnement littoral correspond à une nécessité d'observations, sur de longues séries temporelles, et de mesures à des fréquences élevées. Il est le résultat d'une analyse des besoins des différents types...Contributeur (s):

Heral, Maurice / Berthome, Jean-paul - 1991The impact of the main parameters of water quality which act on the life history of molluscs are presented. Two types of parameters are examined: the first are the physical-chemical parameters as temperature, salinity, turbidity, oxygen concentrations. They can be modified by perturbations directly...Contributeur (s):

Belin, Catherine / Berthome, Jean-paul - 1988In 1986, 23 discolored waters were observed ; dinoflagellates often were the cause of them. Many developments of Prorocentrum minimum occured ; two of them were associated with shel1fishes mortalities. At contrary, other species which are suspected to be toxic for shellfishes, as Gyrodinium...Contributeur (s):

Berthome, Jean-paul / Belin, Catherine - 1988In 1985, twenty discolored waters have been observed with dinoflagellates as the most frequently encountered group. Shellfishes mortalities due to occurence of Gyrodinium spirale were observed in Etang de Thau. Likewise, the growth of molluscs juveniles was inhibited by a bloom of Gyrodinium...Contributeur (s):
