    • Ancient DNA (aDNA) has played a major role in our understanding of the past. Important advances in the sequencing and analysis of aDNA from a range of organisms have enabled a detailed understanding of processes such as past demography, introgression, domestication, adaptation and speciation. However, to date and with the notable exception of microbiomes and sediments, most aDNA studies have focused on single taxa or taxonomic groups, making the study of changes at the community level challenging. This is rather surprising because current sequencing and analytical approaches allow us to obtain and analyse aDNA from multiple source materials. When combined, these data can enable the simultaneous study of multiple taxa through space and time, and could thus provide a more comprehensive understanding of ecosystem-wide changes. It is therefore timely to develop an integrative approach to aDNA studies by combining data from multiple taxa and substrates. In this review, we discuss the various applications, associated challenges and future prospects of such an approach.

  • Contesting Marginality : The Boreal Forest of Middle Scandinavia and the Worlds Outside
  • 2021

  • Tidskriftsartikel (refereegranskat)abstract
    • In this article, we present ongoing archaeological research into Scandinavia's forested inland region, suggesting that its people and communities were socially and economically integrated into systems of trade and in close interaction with the worlds outside, as early as the first centuries of the Common Era. The article presents a range of archaeological evidence, from ca. 500 to 1400 CE, for processes of ecological globalization, manifested by the exploitation of local landscapes and the extraction of valued products that could be transformed into commodities through crafts and trade. These forested landscapes were reliant on—and also shaped by—complex social and economic relations reflecting interrelated socio-economic systems of extraction, production, and consumption. Our main argument is that these landscapes are crucial to identifying and understanding the contours of the premodern global North.
