    • Ancient DNA, Lipid Biomarkers and Palaeoecological Evidence Reveals Construction and Life on early Medieval Lake Settlements 

      Brown, Antony; van Hardenbroek, Maarten; Fonville, Thierry; Davies, Kimberley L.; Mackay, Helen; Murray, E; Head, Katie; Barratt, Phil; McCormick, F; Ficetola, Fransesco Gentil; Henderson, Andrew; Crone, Anne; Cavers, G; Langdon, Peter G.; Whitehouse, Nicki J.; Pirrie, Duncan; Alsos, Inger Greve; Gielly, L (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-06-03)
      Direct evidence of ancient human occupation is typically established through archaeological excavation. Excavations are costly and destructive, and practically impossible in some lake and wetland environments. We present here an alternative approach, providing direct evidence from lake sediments using DNA metabarcoding, steroid lipid biomarkers (bile acids) and from traditional environmental analyses. ...

    • Characterising life in settlements and structures: Incorporating faecal lipid biomarkers within a multiproxy case study of a wetland village 

      Mackay, Helen; Davies, Kimberley T A; Roberston, J; Roy, L; Bull, Ian D.; Whitehouse, Nicki J.; Crone, A; Cavers, G; McCormick, F; Brown, Antony; Henderson, Andrew (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-07-25)
      Roundhouses are ubiquitous features of Iron Age landscapes across North West Europe, yet the way they were used internally is not well understood. We demonstrate how spatial analyses of steroid lipid biomarkers advances our understanding of household activities, living conditions and animal management associated with a well-preserved 5th century BCE roundhouse from Scotland's first Iron Age wetland ...

    • New integrated molecular approaches for investigating lake settlements in north-western Europe 

      Brown, Antony; Fonville, Thierry; Van Hardenbroek, Maarten; Cavers, Graeme; Crone, Anne; Mccormick, Finbar; Murray, Emily; Mackay, Helen; Whitehouse, Nicki J.; Henderson, Andrew C.G.; Barratt, Phil; Davies, Kim; Head, Katie; Langdon, Peter; Alsos, Inger Greve; Pirrie, Duncan (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-09-28)
      Lake settlements, particularly crannogs, pose several contradictions—visible yet inaccessible, widespread yet geographically restricted, persistent yet vulnerable. To further our understanding, we developed the integrated use of palaeolimnological (scanning XRF, pollen, spores, diatoms, chironomids, Cladocera, microcharcoal, biogenic silica, SEM-EDS, stable-isotopes) and biomolecular (faecal stanols, ...
