Clitellate worms (Annelida) in late-glacial and Holocene sedimentary DNA records from the Polar Urals and northern Norway
(Journal article; Tidsskriftartikkel; Peer reviewed, 2018-11-26)While there are extensive macro‐ and microfossil records of a range of plants and animals from the Quaternary, earthworms and their close relatives amongst annelids are not preserved as fossils and therefore the knowledge of their past distributions is limited. This lack of fossils means that clitellate worms (Annelida) are currently underused in palaeoecological research, even though they can provide ... -
Environmental DNA of aquatic macrophytes: The potential for reconstructing past and present vegetation and environments
(Journal article; Tidsskriftartikkel; Peer reviewed, 2023-07-29)1. Environmental DNA is increasingly being used to reconstruct past and present biodiversity including from freshwater ecosystems. Macrophytes are especially good environmental indicators, thus their environmental DNA palaeorecord might shed light on past postglacial environments.<p> <p>2. Here, we first review and compare studies that use metagenomics, targeted capture, and various barcoding ... -
Exotic pollen in sediments from the high Arctic Lake Tenndammen, Svalbard archipelago: diversity, sources, and transport pathways
(Journal article; Tidsskriftartikkel; Peer reviewed, 2024-01-18)We analysed the pollen and spores extracted from 73 samples of lacustrine sediments from Colesdalen in Svalbard (Lake Tenndammen) as well as 10 soil samples collected from the lake’s shores. In total, 56 pollen taxa were recorded from the sediments spanning the last 800 years, whilst 35 pollen types were found in the soil samples. Pollen was categorised as (i) regional (from Svalbard); (ii) ... -
Holocene floristic diversity and richness in northeast Norway revealed by sedimentary ancient DNA (sedaDNA) and pollen
(Journal article; Tidsskriftartikkel; Peer reviewed, 2018-10-30)We present a Holocene record of floristic diversity and environmental change for the central Varanger Peninsula, Finnmark, based on ancient DNA extracted from the sediments of a small lake (<i>sed</i>aDNA). The record covers the period c. 10 700 to 3300 cal. a BP and is complemented by pollen data. Measures of species richness, sample evenness and beta diversity were calculated based on <i>sed</i>aDNA ... -
Human-environment interactions in the Mesolithic – The case of site Paliwodzizna 29, a lakeside site in central Poland
(Journal article; Tidsskriftartikkel; Peer reviewed, 2023-11-10)Human-environmental relations before agriculture can be revealed at archaeological sites through multi-method palaeoenvironmental studies, particularly at sites which have both dryland and wetland areas. Paliwodzizna 29 is such as site, being a series of pits and hearths at the edge of Lake Grodno in Central Poland. A combination of faunal analysis, lithostratigraphy, pollen, diaspores, charcoal and ... -
Rapid laminated clastic alluviation associated with increased Little Ice Age flooding co-driven by climate variability and historic land-use in the middle Severn catchment, UK
(Journal article; Tidsskriftartikkel; Peer reviewed, 2023-10-06)The analysis of exceptionally well-preserved visible clastic laminations in deep alluvial sediments at Kempsey, Worcestershire (UK), allows a new highresolution analysis of late-Holocene flood-history in the largest UK catchment, as well as local human response. At the sample site over 4.5m of sandy-silt overbank-alluvium accumulated on the floodplain and optically stimulated luminescence (OSL) ...
