Última Etude théorique des interactions entre des dinoflagellés et des parasitoïdes eucaryotes en environnement mélangé : persistance du système et succession phytoplanctonique ArchiMer Arancio, Marc. Many species of autotrophic dinoflagellates can be parasitized by multiple eukaryotic parasitoids. These parasitoids have a specific life cycle resulting in the death of the host and the release of hundreds of zoospores that can infect a new host. Several studies have demonstrated their potential to control the host population in a few days as well as their great diversity and suggests a very complex dynamics of infection in this kind of environment. The objective of this thesis is to understand the parasitoid-dinoflagellates infection dynamics in a highly mixed estuary and a better understanding of the different interactions taking place within this system. To address this problem, we used the modeling approach (IBM). This approach has enabled to show...

Theoretical studies have usually been used to explain host–parasitoid persistence in conditions of spatial heterogeneity or in homogeneous environments with specific conditions. In shallow estuaries where spatial heterogeneity is prevented by tides and river input, a common host–parasitoid system (dinoflagellate-Amoebophrya spp.) is able to persist even in the absence of specific conditions described in the literature. Recent observations have revealed that the cyst stage (during which the dinoflagellate host can survive in difficult environmental conditions in a dormant stage) can be infected by the parasitoid. The encystment/excystment process is suspected to be the basis for the long-term persistence of the system. In this work, the coexistence of...
