On The Physics of Glaciations

open access: yes, 2023
Future carbon neutral or low carbon economies will inevitably restore past climate regulating parameters.  The physics of past climates appears to be an ongoing research subject.  Past surface temperature variations were induced by changes in the size of green matter and amplified by the ocean.  Future climates may be managed by photosynthesis.

Pleistocene climate fluctuations as the major driver of genetic diversity and distribution patterns of the Caspian green lizard, Lacerta strigata Eichwald, 1831

open access: yesEcology and Evolution, 2021
Green lizards of the genus Lacerta have served as excellent models for studying the impact of Pleistocene climatic oscillations on genetic structures. The Caspian green lizard, Lacerta strigata, occupies various habitats across the Caucasus and the South

À propos d’un outil à retouches bifaciales du Paléolithique moyen trouvé dans le Bugey au Petit Abergement(commune de Haut-Valromey, Ain)

open access: yesRevue Archéologique de l’Est, 2021
In our region, it is remarkable to discover a flint tool with bifacial retouch, especially in an environmental context that has few Paleolithic remains. This piece, collected with no archaeological context, raises questions concerning its chrono-cultural
