We assembled genome-wide data from 271 ancient Iberians, of whom 176 are from the largely unsampled period after 2000 BCE, thereby providing a high-resolution time transect of the Iberian Peninsula. We document high genetic substructure between northwestern and southeastern hunter-gatherers before the spread of farming. We reveal sporadic contacts between Iberia and North Africa by~2500 BCE and, by~2000 BCE, the replacement of 40% of Iberia's ancestry and nearly 100% of its Y-chromosomes by people with Steppe ancestry. We show that, in the Iron Age, Steppe ancestry had spread not only into Indo-European-speaking regions but also into non-Indo-European-speaking ones, and we reveal that present-day Basques are best described as a typical Iron Age population without the admixture events that later affected the rest of Iberia. Additionally, we document how, beginning at least in the Roman period, the ancestry of the peninsula was transformed by gene flow from North Africa and the eastern Mediterranean.
In Western Europe, the transition from the middle Iron Age to the early Roman period implied changes in livestock practices, with the emergence of a specialized and selective animal husbandry. These changes have been related in Italy and south of France with changes in livestock management involving their mobility between ecologically complementary areas. The study of this question in the Iberian Peninsula has only been partially investigated through palaeoenvironmental analyses, and the information about the origin and significance of this phenomenon is very scarce. To shed new light on this topic we used an archaeozoological approach, with the application of geometric morphometrics. They were used to study size and shape variability in sheep astragali from 9 sites dating from the middle Iron Age to the early Roman period (5th c. BC-3rd c. AD) and located on the Pyrenees and on the north-eastern Iberian coast as a case study. The results we obtained, combined with Number of Identified Specimens (NISP) and kill-off patterns, showed local specificities in terms of breeding methods and sheep morphologies between the two areas during the middle Iron Age. On the contrary, sheep with similar size and the implementation and development of similar sheep husbandry practices in the Pyrenees and the north-eastern Iberian coast were documented during the early Roman period. These results suggest the existence of livestock links between these two areas during the Roman period, that could be involved a possible movement of sheep between the lowlands and the Pyrenees for the first time.
Purpose -The Roses Citadel is a bastioned fortification that has archaeological remains from the Greek, Roman and medieval periods in its interior. Currently, the area inside the Citadel is used for a wide range of activities; some directly related with the heritage item, others associated with its use as a public space for the town. The purpose of this paper is to analyse the economic interest of charging an entrance fee vs the alternative of free access and offers a framework to address this issue. Design/methodology/approach -The proposal is to consider the marginal cost of increasing the number of users and to carry out a travel cost analysis. It is vital to take into account the results of specifically economic analyses, but the evaluations of social policies should also be considered, and should have a considerable weight in decision making. Findings -It is proposed that free entry would bring about an increase in the number of visitors and users of Roses Citadel. In turn, this increase would lead to a greater social use of this heritage asset, and a chance for the least privileged sectors of society to use the site more. Financial resources for the maintenance of the asset would not be raised through entry fees, but through contributions relating to the increase in the social consideration of the site. Originality/value -In the context of a discussion on the advantages and disadvantages of paying an entry fee for heritage assets, the example of Roses Citadel provides several factors for consideration. It shows that payment of an entry fee affects use of the site by society, and particularly by the local community, whereas free access leads to a wide range of opportunities for use.
