  • Lake sedimentary dna research on past terrestrial and aquatic biodiversity: Overview and recommendations
  • 2021
  • Ingår i: Quaternary. - : MDPI. - 2571-550X. ; 4:1
  • Forskningsöversikt (refereegranskat)abstract
    • The use of lake sedimentary DNA to track the long-term changes in both terrestrial and aquatic biota is a rapidly advancing field in paleoecological research. Although largely applied nowadays, knowledge gaps remain in this field and there is therefore still research to be conducted to ensure the reliability of the sedimentary DNA signal. Building on the most recent literature and seven original case studies, we synthesize the state-of-the-art analytical procedures for effective sampling, extraction, amplification, quantification and/or generation of DNA inventories from sedimentary ancient DNA (sedaDNA) via high-throughput sequencing technologies. We provide recommendations based on current knowledge and best practises.

  • Macro-, meso- and micro-charcoal from the Epigravettian settlements of Mezhyrich (Ukraine): Taphonomical and anthracological issues
  • 2015
  • Ingår i: L'Anthropologie. - : Elsevier BV. - 0003-5521. ; 119:4, s. 487-504
  • Tidskriftsartikel (refereegranskat)abstract
    • This paper is the state of the art of charcoal signal studies (macro-, meso- and micro-charcoal) that have been carried out at the Epigravettian settlement of Mezhyrich. This work took part of the French ANR project "Mammouths". Charcoal signals have been found in both natural and archaeological (pits and activity areas) deposits that have been sampled during the 2007-2008 archaeological excavations. This study aims at discussing the natural versus anthropic causes of those charcoal signals. Microscopic charcoal have been observed and quantified from loess sediments; they are probably the consequence of regional fire regimes. Charcoal signals found in archaeological layers would be mainly caused by human activities. The major charcoal signal is observed within the microscopic part of the archaeological sediments and thereby underlines the intensity of taphonomic processes. The identification of wood charcoal shows that birch and willow were located along the riverbanks, which provides further discussion of prehistoric fuel management in Pleniglacial context.
