Identifying mobility in populations with mixed marine/terrestrial diets : strontium isotope analysis of skeletal material from a passage grave in Resmo, Öland, Sweden

Strontium isotope analysis of skeletal material as a means to reconstruct prehistoric residential patterns has previously mainly been applied to populations with terrestrial diets. Here we present a model for populations with mixed marine/terrestrial diets, which is based on two-component mixing of strontium isotopes. Applying this model, we can estimate the original strontium isotope value of the terrestrial component of the diet. Accordingly it is possible to identify non-local individuals even if they had a mixed marine/terrestrial diet. The model is applied to tooth enamel samples representing nine individuals recovered from a passage grave in Resmo, on the island of Öland in the Baltic Sea, where at least five non-local individuals, representing at least two different geographical regions of origin, were identified. Non-local individuals were more frequent during the Bronze Age than during previous phases.

“Samira Doesn’t Live Here Any More” : Somali-Swedes’ mobility as transnational practice

This article explores transnational experiences within a group of Somali- Swedes, particularly how parents’ transnational practices are transferred to their children and how a transnational social space, built on close relationships on a global scale, is constructed. The readiness to relocate between countries and the implications for the children is illuminated. The onward migration to Egypt is highlighted as an example. According to research on Somalis in diaspora, they explain their propensity to move by claiming to be nomads, but this article indicates that it is also about their desire for better opportunities in combination with the cultural and economic marginalisation experienced in the West.
