    • A 24,000-year ancient DNA and pollen record from the Polar Urals reveals temporal dynamics of arctic and boreal plant communities 

      Clarke, Charlotte L.; Alsos, Inger Greve; Edwards, Mary E.; Paus, Aage; Gielly, Ludovic; Haflidason, Haflidi; Mangerud, Jan; Regnéll, Carl; Hughes, Paul D.M.; Svendsen, John-Inge; Bjune, Anne Elisabeth (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-09-18)
      A 24,000-year record of plant community dynamics, based on pollen and ancient DNA from the sediments (<i>seda</i>DNA) of Lake Bolshoye Shchuchye in the Polar Ural Mountains, provides detailed information on the flora of the Last Glacial Maximum (LGM) and also changes in plant community composition and dominance. It greatly improves on incomplete records from short and fragmented stratigraphic sequences ...

    • The drivers of plant community composition have shifted from external to internal processes over the past 20,000 years 

      Doncaster, C. Patrick; Edwards, Mary E.; Clarke, Charlotte L.; Alsos, Inger Greve (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-05-19)
      Internal and external factors regulating the past composition of plant communities are difficult to identify in palaeo-vegetation records. Here, we develop an index of relative entropy of community assembly, which applies to changes in the composition of a community over time, measuring disorder in its assembly relative to disassembly. Historical periods of relatively ordered assembly (negative ...

    • Lake Sedimentary DNA Research on Past Terrestrial and Aquatic Biodiversity: Overview and Recommendations

L.; Epp, Laura S.; Domaizon, Isabelle; Alsos, Inger G.; Parducci, Laura (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-02-13)
      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 ...

    • Rapid climate changes during the Lateglacial and the early Holocene as seen from plant community dynamics in the Polar Urals, Russia 

      Bjune, Anne E.; Greve Alsos, Inger; Brendryen, Jo; Edwards, Mary E.; Haflidason, Haflidi; Johansen, Maren S.; Mangerud, Jan; Paus, Aage; Regnéll, Carl; Svendsen, John-Inge; Clarke, Charlotte L. (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-07-30)
      A detailed, well-dated record of pollen and sedimentary ancient DNA (sedaDNA) for the period 15 000–9500 cal a bp describes changes at Lake Bolshoye Shchuchye in the Polar Ural Mountains, located far east of the classical Lateglacial sites in western Europe. Arctic tundra rapidly changed to lusher vegetation, possibly including both dwarf (Betula nana) and tree birch (B. pubescens), dated in our ...
