Le cycle biologique de Cyclops vicinus vicinus (Copepoda, Cyclopoida) dans la retenue de Serre-Ponçon (Hautes-Alpes)
The life cycle of Cyclops vicinus vicinus (Copepoda, Cyclopoida) in the reservoir of Serre-Ponçon (High Alps)
Laboratoire d'Hydrobiologie, Université de Provence, I place Victor Hugo. 13331 Marseille Cedex 3
L'étude du cycle biologique de Cyclops vicinus vicinus à trois stations du réservoir de Serre-Ponçon révèle l'existence d'une hétérogénéité du milieu, tant au niveau des effectifs que du nombre de générations annuelles. Les variations observées s'expliquent par des phases de vie latente (diapause ou quiescence) dont le déterminisme est discuté.
Abstract
A study of the life cycle of Cyclops vicinus vicinus at three stations in the reservoir of Serre-Ponçon showed that the heterogeneity of the environment was sufficient to effect the number of generations per year. The observed variations could be explained by the phases of resting stages (diapause or quiescence) and the reasons for this are discussed.
