• 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 ...

    • Plant DNA metabarcoding of lake sediments: How does it represent the contemporary vegetation 

      Alsos, Inger Greve; Lammers, Youri; Yoccoz, Nigel Gilles; Jørgensen, Tina; Sjögren, Per; Gielly, Ludovic; Edwards, Mary E. (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-04-17)
      Metabarcoding of lake sediments have been shown to reveal current and past biodiversity, but little is known about the degree to which taxa growing in the vegetation are represented in environmental DNA (eDNA) records. We analysed composition of lake and catchment vegetation and vascular plant eDNA at 11 lakes in northern Norway. Out of 489 records of taxa growing within 2 m from the lake shore, ...
