RESUMO
The Roman period saw the empire expand across Europe and the Mediterranean, including much of what is today Great Britain. While there is written evidence of high mobility into and out of Britain for administrators, traders, and the military, the impact of imperialism on local, rural population structure, kinship, and mobility is invisible in the textual record. The extent of genetic change that occurred in Britain during the Roman military occupation remains underexplored. Here, using genome-wide data from 52 ancient individuals from eight sites in Cambridgeshire covering the period of Roman occupation, we show low levels of genetic ancestry differentiation between Romano-British sites and indications of larger populations than in the Bronze Age and Neolithic. We find no evidence of long-distance migration from elsewhere in the Empire, though we do find one case of possible temporary mobility within a family unit during the Late Romano-British period. We also show that the present-day patterns of genetic ancestry composition in Britain emerged after the Roman period.

Inclusion of osteological material in primatological research has a long history, and use of skeletal remains continues to be important in anatomical and anthropological research. Here we report a set of proven methods, including equipment, protocol, and procedure, which enable relatively simple acquisition of skeletal material from naturally deceased animals in field sites and sanctuaries. Such skeletal material, often with extensive accompanying life-history data, is a unique and valuable source of data for both academic and conservation-based research.
