"Biodiversity, biostratigraphy, disparity and macroecology of middle Eocene radiolarians (Rhizaria) : insights to their biotic response to the Middle Eocene Climatic Optimum (MECO)."

The Middle Eocene Climatic Optimum (MECO) is a global warming event that occurred ca. 40 Ma and temporarily interrupted the long-term Eocene cooling trend. Although the MECO represents one of the larger climatic disruptions of the Paleogene, its impact on the biosphere is still poorly understood. Based on a wide range of quantitative methods, this thesis aims to study the radiolarian paleodiversity dynamics and morphological disparity through the MECO, in order to gain a deeper understanding of the biotic perturbations associated with this climatic event. The taxonomic understanding of middle Eocene radiolarian species was first clarified, by documenting at the species level two well-preserved radiolarian faunas recovered from two distinct geographic regions: the equatorial Atlantic (ODP site 1260) and the North Atlantic (ODP site 1051). A total of 276 species were identified, including 37 new to science. Taking advantage of the cyclostratigraphic framework developed at Site 1260, we refined the global tropical radiolarian biozonation. The absolute ages of 71 radiolarian bioevents were calibrated and, by comparison with the equatorial Pacific record, the synchroneity of primary bioevents was demonstrated. Once the taxonomic and biostratigraphic frameworks were clarified, the main aim of this thesis was to assess the radiolarian biotic sensitivity to climate change. Two categories of metrics were used to achieve this objective. On the one hand, we performed a whole assemblage quantitative analysis at ODP Site 1051. This detailed investigation of the radiolarian fauna did not reveal any prominent turnover during the MECO, but only a slight increase in radiolarian taxic richness due to the poleward migration of several tropical radiolarian species. On the other hand, we applied geometric morphometric approaches to quantify the morphological disparity of radiolarian shell through the MECO interval. This study was focused on a single species (Podocyrtis papalis) from Site 1260, and showed that fluctuations in morphological disparity coincide with the warmest interval of the MECO. This signal is interpreted as an indicator of biological stress induced by the warming event
