Étude paléogénétique du cerf élaphe (Cervus elaphus) au cours de la transition Tardiglaciaire - Holocène ancien du Jura (15 000 – 6 000 BP) : relations entre changements morphologiques, environnementaux et génétiques
… the hunters-gatherers during this unstable time. Isotopic geochemistry has already showed that during this period, the habitat and the diet of deers changed. Moreover, morphological studies is demonstrating that, in the same way, the size of deers seems to decrease. To complete both studies, a …

SILICON ISOTOPE AND PETROGRAPHIC INVESTIGATIONS OF SILICIFIED CARBONATE ROCKS: IMPLICATIONS FOR IMPROVED PARAGENETIC SEQUENCING AND PROXIES FOR PALEOZOIC OCEAN CHEMISTRY
… isotopes in geologic studies, the silicon isotopic budget and cycle in ancient oceans is still poorly constrained. This study uses silicon isotopic data from silicified carbonate rocks to investigate their paragenesis and discusses the implications of the data to the silicon isotopic budget …
