Meunier, Mathias. "Biodiversity, biostratigraphy, disparity and macroecology of middle Eocene radiolarians (Rhizaria) : insights to their biotic response to the Middle Eocene Climatic Optimum (MECO)." Electronic Thesis or Diss., Université de Lille (2022-....), 2023. http://www.theses.fr/2023ULILR078.
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

The early Eocene is marked by a succession of major global warming events that culminated in a period of climatic optimum (EECO) corresponding to the warmest period of the Cenozoic. Due to their short duration and high intensity, these hyperthermal events are often considered as the best analogues of current global warming, and are correlated with important diversification of mammals in the North American fossil record. In Europe, the early Eocene localities are less well known and it is difficult to trace the impact of these climatic events. Lophiodontidae are a family of perissodactyl mammals found in abundance in European Eocene localities, particularly in southern France, making them a model of choice for studying the impacts of hyperthermal events on the evolutionary history of European mammals. The first part of this work consists of an exhaustive study of the intraspecific variability of this family. More than thirty polymorphic dental characters have been identified, as well as the presence of marked sexual dimorphism. The genus Paralophiodon has been revised in light of this high variability and is considered invalid. In all, several hundred specimens from 22 localities in southern Europe were studied and 2 new species belonging to the genus Eolophiodon have been identified. The revision of the lophiodontids of the Occitanie region, placed in a biostratigraphic framework, allow us to rediscuss of the controversial age of the “grès d’Aigne”, and to propose a late Ypresian-early Lutetian age (MP10b-MP11) for this formation, thus filling the previous known gap in the European fossil record. The study of basal lophiodontids, coupled with the results of a new phylogenetic analysis, places the lophiodontids close to chalicothera within the suborder Ancylopoda, suggesting an Asian origin of the family and an arrival of lophiodontids in southern Europe soon after PETM. The study of unpublished material and phylogenetic analyses constrained by the new biostratigraphic data make it possible to distinguish three major phases in the evolutionary history of lophiodontidae that seem to be correlated with the major climate changes of the Eocene. Basal radiation of lophiodontidae is contemporary to the hyperthermal events of the Ypresian and is marked by the multiplication of small size forms and is restricted to the Mesogean Province. The second radiation of lophiodontidae appears contemporaneous with the EECO and its marked by the appearance of the genus Lophiodon and the replacement of small sub-cursorial forms by more massive taxa with sligthly more molarized premolars. This radiation marks the end of the endemism of lophidontidae that dispersed throughout all Western Europe. Lophiodontidae radiate one last time at Lutetien during the post-EECO cooling, during the "Intra Eocene Mammal Turnover I". This radiation sees the introduction of giant forms (one to two tons), graviportal and with molarized teeth, interpreted as a response to the relative opening of the environment during the post-EECO cooling leading to drastic changes in diets

The goal of this work was providing experimental data to better constrain the impact of global warming on permafrost. Methodology was based on physical modeling in a cold room. This allows identifying and defining the evolution processes of the experimental permafrost. Experimental permafrost was built-up based on available field data. The lithology of the material used was a mixture of fine sand and loam from the plain of Caen. Ice content is between 30 and 80 %. Models are not scaled and dimensional problems are not considered. Indeed, these experiments are a preliminary work. This study on the behaviour of an experimental warming permafrost allows a better understanding of (i) the changes in topography (thaw-settlement), (ii) the changes in the active layer, (iii) the thermal evolution of an experimental permafrost (freezing and thawing fronts monitoring) and (iv) the influence of different parameters (temperature, lithology, water-content, ice-content and ice-layer). This work has contributed to the development of new experimental techniques and it will enhance physical modeling databases on permafrost

The unprecedented pace of warming of the Arctic Ocean affect a wide range of pelagic processes, from microalgal production to fish recruitment. Sediment traps deployed on oceanographic moorings at the Beaufort Sea shelf break were used to investigate the impact of changes in ice cover and water temperature on the phenology of ice algae, phytoplankton and herbivorous copepods from the Calanus genus. Water temperature, salinity, microalgal fluxes and composition, and zooplankton abundance and composition in the traps were monitored over 5 of the 6 annual cycles from September 2009 to September 2015 (no data in 2014). Satellite-derived sea ice concentration and modeled snow depth were also retrieved for the same period. For 4 of the 5 years monitored, the upward migration of Calanus hyperboreus along with nauplii abundance were synchronized with peaks in diatoms export while the migration of Calanus glacialis preceded the peak in export of the ice algae Nitzschia frigida by 6 to 8 weeks. A disruption of these patterns was observed in 2013 as a mismatch between primary and secondary producers was observed. First, unusual warm water temperatures and significant diatom flux from October to December 2012 led to a shoaling of C. hyperboreus females winter vertical distribution and, thus, important egg spawning above 100 m with numerous nauplii swimming into the trap in March-April. Second, the late snow and ice melt in summer 2013 delayed the ice algae export, resulting in a mismatch with C. glacialis and N. frigida. As ice algae and phytoplankton are essential food source for the reproduction and development of Calanus copepods, a mismatch likely had negative impact on their recruitment and on the subsequent transfer of energy to carnivorous copepods, fish, and seabirds. Such mismatch events between phytoplankton and zooplankton will potentially occur more often owing to the rapidly changing environmental conditions in the Arctic Ocean.
