Foraminifera and testate amoebae are protists observed in all marine and continental aquatic environments, respectively. This thesis summarizes the knowledge about the relationships between these organisms and their environment. These parameters are classified into biological factors (food sources), physical (life position in the environment, depth, altitude, substrate nature) or chemical (mineralogical, nutrient resource characteristics). The effects of environmental parameters are studied at continental, regional and local level. After defining the characteristics of these faunal-environmental relationships, this thesis gives two illustrations of the reconstruction of ancient environments, one on the scale of the Holocene and the other on the scale of the Anthropocene.
