We are in the middle of the course ”Archaeology and quarternary biology”. It is a course we give together with the zoology-department and Love Dalén. And before all, it gives us the possibility to invite some interesting lecturer, specialized in different fields. We have already had Ian Barnes telling us about paleoecology, and here we se Erika Rosengren from Lunds University lecturing about the colonization of southern Scandinavia, the 16th of november. And eventually, during the course, we will also hear Tom Gilbert, Mark Thomas, Pontus Skoglund, Linus Girdland Flink, and Mattias Jakobsson lecture about their specialities. A pretty nice opportunity to be introduced to the field by some rather good scientists.
