Révision de la Grande Coupure européenne : analyse comparée des dynamiques évolutives et de la diversité entre petits et grands mammifères herbivores (Projet financé par le Fond National Suisse)

Juste avant la limite entre l’Éocène et Oligocène, il y a près de 34 millions d’années, le détroit de Turgaï qui séparait l’Europe de l’Asie va subitement s’assécher, entraînant la création de nouveaux ponts terrestres. Ce phénomène est du à une baisse générale du niveau des océans et de la température, une forte accentuation du contraste saisonnier ainsi que l’apparition d’une calotte glaciaire au pôle sud. L’histoire des mammifères terrestres connait alors un bouleversement drastique à l’échelle de l’Eurasie connu sous le nom de Grande Coupure. Cet évènement est particulièrement bien documenté en Europe de l’Ouest. Cependant, à la lumière de récentes découvertes, la chronologie des invasions de mammifères est remise en question, certains groupes apparaissant dès la fin de l’Eocène déjà en Europe de l’Est. Ce projet vise à réétudier la Grande Coupure à l’échelle de l’Europe en précisant son cadre chronologique et son impact sur l’histoire évolutive et la biodiversité des mammifères.

Evolution of the Miocene faunal diversity across Eurasia: to the roots of modern climates (Projet SPARK financé par le Fond National Suisse)

L’idée de ce projet est de suivre la différentiation des climats d’Eurasie sur un transect Est-Ouest, depuis le Japon jusqu’à l’Europe, au cours du Miocène (-23 à -3 Ma) en comparant plusieurs régions localisées entre 35° et 45° de latitude nord. A cette fin, les petits mammifères, particulièrement sensibles aux variations climatiques, seront étudiés dans chaque registre fossile local afin de comparer les évolutions climatiques régionales. En plus des méthodes de reconstructions climatiques et environnementales existantes, de nouvelles méthodes seront développées afin de quantifier les changements climatiques à partir des variations du registre fossile. Ces études s’accompagneront de missions de prospections et d’échantillonnage au Kazakhstan et au Japon afin de compléter ces registres fossiles encore mal connus.
