Between Raetia Secunda and the dutchy of Bavaria: Exploring patterns of human movement and diet.

During the transition from Late Antiquity to the Middle Ages, the Roman Empire dissolved in the West and medieval empires were founded. There has been much discussion about the role that migration played in this transition. This is especially true for the formation of the Baiuvariian tribe and the founding of this tribal dukedom, which took place from the 5th to the 6th century in what is now Southern Bavaria (Germany).

On the premises of mixing models to define local bioavailable Sr/Sr ranges in archaeological contexts.

In archaeological mobility studies, non-local humans and animals can be identified by means of stable strontium isotope analysis. However, defining the range of local Sr/Sr ratios is prerequisite. To achieve this goal, proxy-based mixing models have recently been proposed using Sr/Sr ratios measured in modern local vegetation, water and soil samples.
