Land snail successions in the lower Rhône valley allow us to reconstruct the postglacial recolonization. From the Lateglacial period onwards, Mediterranean steppe communities appeared. The arrival of forest taxa was significantly delayed by aridity. The question of glacial refugia, both local and distant, primarily concerned Mediterranean species of ...

Best Practices in Open and Reproducible Antarctic Marine Sediment Core Research
Abstract Marine sediment cores from Antarctica are archived by national programs for reuse and resampling by future researchers, creating a resourceful way to conduct Antarctic science. With reduced budgets to conduct Antarctic field work and to collect new sediment cores offshore of the icy continent, the accessibility of these archived cores and ...
