Ancient DNA, Lipid Biomarkers and Palaeoecological Evidence Reveals Construction and Life on early Medieval Lake Settlements
(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. ... -
Early to Middle Bronze Age agricultural terraces in north-east England: Morphology, dating and cultural implications
(Journal article; Tidsskriftartikkel; Peer reviewed, 2023-02-06)Terracing is found widely in the Mediterranean and in other hilly and mountainous regions of the world. Yet while archaeological attention to these ‘mundane’ landscape features has grown, they remain understudied, particularly in Northern Europe. Here, the authors present a multidisciplinary study of terraces in the Breamish Valley, Northumberland. The results date their construction to the Early ... -
Lateglacial and Early Holocene palaeoenvironmental change and human activity at Killerby Quarry, North Yorkshire, UK
(Journal article; Tidsskriftartikkel; Peer reviewed, 2022-12-05)The hunter-gatherers that entered the British peninsula after ice-retreat were exploiting a dynamic, rapidly changing environment. Records of vegetation change and human occupation during the Lateglacial to Early Holocene in northern Britain are more commonly found at upland and cave sites. However, recent research highlights many areas of the Swale–Ure Washlands that preserve extensive environmental ... -
Life before Stonehenge: The hunter-gatherer occupation and environment of Blick Mead revealed by sedaDNA, pollen and spores
(Journal article; Tidsskriftartikkel; Peer reviewed, 2022-04-27)The Neolithic and Bronze Age construction and habitation of the Stonehenge Landscape has been extensively explored in previous research. However, little is known about the scale of pre-Neolithic activity and the extent to which the later monumental complex occupied an ‘empty’ landscape. There has been a long-running debate as to whether the monumental archaeology of Stonehenge was created in an ... -
New integrated molecular approaches for investigating lake settlements in north-western Europe
(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 ... -

Paleoeconomy more than demography determined prehistoric human impact in Arctic Norway
(Journal article; Tidsskriftartikkel; Peer reviewed, 2022-10-07)Population size has increasingly been taken as the driver of past human environmental impact worldwide, and particularly in the Arctic. However, sedimentary ancient DNA (sedaDNA), pollen and archaeological data show that over the last 12,000 years, paleoeconomy and culture determined human impacts on the terrestrial ecology of Arctic Norway. The large Mortensnes site complex (Ceavccagea ¯dgi, 70◦N) ... -
Postglacial species arrival and diversity buildup of northern ecosystems took millennia
(Journal article; Tidsskriftartikkel; Peer reviewed, 2022-09-28)What drives ecosystem buildup, diversity, and stability? We assess species arrival and ecosystem changes across 16 millennia by combining regional-scale plant sedimentary ancient DNA from Fennoscandia with near-complete DNA and trait databases. We show that postglacial arrival time varies within and between plant growth forms. Further, arrival times were mainly predicted by adaptation to temperature, ... -
Sedimentary ancient DNA reveals local vegetation changes driven by glacial activity and climate.
(Journal article; Tidsskriftartikkel; Peer reviewed, 2023-01-07)Disentangling the effects of glaciers and climate on vegetation is complicated by the confounding role that climate plays in both systems. We reconstructed changes in vegetation occurring over the Holocene at Jøkelvatnet, a lake located directly downstream from the Langfjordjøkel glacier in northern Norway. We used a sedimentary ancient DNA (sedaDNA) metabarcoding dataset of 38 samples from a ... -
Soil organic carbon stabilization mechanisms and temperature sensitivity in old terraced soils
(Journal article; Tidsskriftartikkel; Peer reviewed, 2021-12-08)Being the most common human-created landforms, terrace construction has resulted in an extensive perturbation of the land surface. However, our mechanistic understanding of soil organic carbon (SOC) (de-)stabilization mechanisms and the persistence of SOC stored in terraced soils is far from complete. Here we explored the factors controlling SOC stability and the temperature sensitivity (<i>Q</i>< ... -
Towards a Jōmon food database: construction, analysis and implications for Hokkaido and the Ryukyu Islands, Japan
(Journal article; Tidsskriftartikkel; Peer reviewed, 2022-06-27)One of the most entrenched binary oppositions in archaeology and anthropology has been the agriculturalist vs hunter-gatherer-fisher dichotomy fuelling a debate that this paper tackles from the bottom-up by seeking to reconstruct full past diets. The Japanese prehistoric Jōmon cultures survived without fully-developed agriculture for more than 10,000 years. Here we compile a comprehensive, holistic ... -
Volume estimation of soil stored in agricultural terrace systems: a geomorphometric approach
(Journal article; Tidsskriftartikkel; Peer reviewed, 2021-09-06)High-resolution topographic (HRT) techniques allow the mapping and characterization of geomorphological features with wide-ranging perspectives at multiple scales. We can exploit geomorphometric information in the study of the most extensive and common landforms that humans have ever produced: agricultural terraces. We can only develop an understanding of these historical landform through in-depth ...
