  • Commercial late medieval bog peat exploitation in the Low Countries

    Open AccessJ Sevink, Bas Van Geel et al.ARTICLELandscape History2025

    The ‘Monnikenven’ is a former, isolated peat bog in the Pleistocene sand landscape near Hilversum (Central Netherlands), During works aiming at restoration of the original mire, a very regular pattern of peat extraction pits was discovered, covering the whole former bog. The pits were separated by vertical, sharply cut, narrow in situ walls, composed of residual bog deposits. Datings by Optical Stimulated Luminescence analysis (osl) of pit fills …

  • On the Use of Spores of Coprophilous Fungi Preserved in Sediments to Indicate Past Herbivore Presence

    Open AccessClaire M Lee, Bas Van Geel et al.ARTICLEQuaternary2022

    Fungal spores that grew on the faeces of herbivores in the past can be extracted from sediments and used to identify the presence of herbivores in former ecosystems. This review: (i) examines the factors that should be considered when interpreting these fungal spores, (ii) assesses the degree to which they can be used to estimate past herbivore populations and biomass density change, and (iii) identifies gaps in our current understanding that lim…

  • The origin of alkaline fen in the Mosbeek Valley in the Netherlands is due to human impact rather than a natural development

    Open AccessHarm Smeenge, A M Kooijman et al.ARTICLEThe Holocene2022Referências: 2

    Alkaline fens are important Natura 2000 habitats, which harbor many endangered plant species. Alkaline fens are formed in areas with groundwater discharge and usually developed in a natural way in the early Holocene. We radiocarbon dated the base of three peat deposits from spring fens along the flanks of the ice-pushed ridge near the village of Ootmarsum to find out when and why peat-forming vegetation started to grow. We cored a sequence in the…

  • NPP-Id

    Open AccessLyudmila Shumilovskikh, Elena S Shumilovskikh et al.ARTICLEVegetation History and…2021Citada por: 13Referências: 1

    Non-pollen palynomorphs (NPPs) form a large group of biological objects found in palynological slides besides pollen grains. This includes various remains of algae and fungi, shells, resting stages and eggs of invertebrates, among others. Publications of NPP-types started in the 1970s with studies of BvG and colleagues, and large numbers of new types continue to be published every year. For an overview of this diverse world of “extra fossils”, we…

  • Multicore Study of Upper Holocene Mire Development in West-Frisia, Northern Netherlands

    Open AccessBas Van Geel, Otto Brinkkemper et al.ARTICLEQuaternary2020

    We studied twelve late Holocene organic deposits in West-Frisia, The Netherlands. Pollen, spores, non-pollen palynomorphs, mosses, other botanical macrofossils and insect remains were recorded for reconstructions of changing environmental conditions. Eastern West-Frisia was a cultivated landscape during the Bronze Age, but it became a freshwater wetland in the Late Bronze Age. In most of our sites, radiocarbon dates show that time transgressive i…

  • Evidence for the diet and habitat of two late Pleistocene mastodons from the Midwest, USA

    Open AccessHilary H Birks, Bas Van Geel et al.ARTICLEQuaternary Research2019

    We analyzed intestinal contents of two late-glacial mastodons preserved in lake sediments in Ohio (Burning Tree mastodon) and Michigan (Heisler mastodon). A multi-proxy suite of macrofossils and microfossils provided unique insights into what these individuals had eaten just before they died and added significantly to knowledge of mastodon diets. We reconstructed the mastodons’ habitats with similar multi-proxy analyses of the embedding lake sedi…

  • A multidisciplinary study of a Late Pleistocene arctic ground squirrel ( Urocitellus parryii ) midden from Yukon, Canada

    Open AccessBram W Langeveld, Bram Langeveld et al.ARTICLEQuaternary Research2018

    Middens (nests and caches) of Late Pleistocene arctic ground squirrels ( Urocitellus parryii ) that are preserved in the permafrost of Beringia archive valuable paleoecological data. Arctic ground squirrels selectively include the plant material placed in middens. To account for this selectivity bias, we used a multi-proxy approach that includes ancient DNA (aDNA) and macro- and microfossil analyses. Here, we provide insight into Pleistocene vege…

  • Columbus’ environmental impact in the New World

    Open AccessHenry Hooghiemstra, Thomas Olijhoek et al.ARTICLEThe Holocene2018Citada por: 8Referências: 19

    Columbus' arrival in the New World in AD 1492 on the northern coast of Hispaniola was followed by a suite of changes in land-use. We reconstruct environmental change from a 225-cm-long sediment core from site Los Indios from an abandoned and sediment-filled meander of the Yaque River, Cibao Valley, northeastern Dominican Republic. The sediment record starts ca. AD 195 (ca. 1755 cal. yr BP) and the history of the meander infill was monitored by ch…

  • Centennial-scale lake-level lowstand at Lake Uddelermeer (The Netherlands) indicates changes in moisture source region prior to the 2.8-kyr event

    Open AccessStefan Engel, S Engels et al.ARTICLEThe Holocene2016

    The Uddelermeer is a unique lake for The Netherlands, containing a sediment record that continuously registered environmental and climatic change from the late Pleistocene on to the present. A 15.6-m-long sediment record was retrieved from the deepest part of the sedimentary basin and an age–depth model was developed using radiocarbon dating, 210 Pb dating, and Bayesian modeling. Lake-level change was reconstructed using a novel combination of hi…

  • Raised bed agriculture in northwest Europe triggered by climatic change around 850 BC

    Open AccessW Groenman-Van Waateringe, Bas Van GeelARTICLEEnvironmental Archaeology2016Citada por: 8Referências: 1

    A sudden decline of solar activity around 850 calendar years BC caused a shift to a cool and wet climate in northwest Europe. Food production suddenly became problematic because of shorter, wetter growing seasons and increased night frost. This climate change triggered innovation and the development of a new agricultural system in continental northwestern Europe: arable farming on raised beds (Celtic field banks) laid out in a more or less checke…

  • Pollen‐based quantitative reconstructions of Holocene regional vegetation cover (plant‐functional types and land‐cover types) in Europe suitable for climate modelling

    Open AccessAnna‐Kari Trondman, A-K Trondman et al.ARTICLEGlobal Change Biology2015

    We present quantitative reconstructions of regional vegetation cover in north‐western Europe, western Europe north of the Alps, and eastern Europe for five time windows in the Holocene [around 6k, 3k, 0.5k, 0.2k, and 0.05k calendar years before present ( bp )] at a 1° × 1° spatial scale with the objective of producing vegetation descriptions suitable for climate modelling. The REVEALS model was applied on 636 pollen records from lakes and bogs to…

  • Analysis of coprolites from the extinct mountain goat Myotragus balearicus

    Open AccessFrido Welker, Elza Duijm et al.ARTICLEQuaternary Research2014

    Humans colonized the Balearic Islands 5–4 ka ago. They arrived in a uniquely adapted ecosystem with the Balearic mountain goat Myotragus balearicus (Bovidae, Antilopinae, Caprini) as the only large mammal. This mammal went extinct rapidly after human arrival. Several hypotheses have been proposed to explain the extinction of M. balearicus . For the present study ancient DNA analysis (Sanger sequencing, Roche-454, Ion Torrent), and pollen and macr…

  • Non-pollen palynomorphs show human- and livestock-induced eutrophication of Lake Nussbaumersee (Thurgau, Switzerland) since Neolithic times (3840 bc )

    Open AccessMartina Hillbrand, Bas Van Geel et al.ARTICLEThe Holocene2014Referências: 8

    Lake Nussbaumersee, located SW of Lake Constance (Switzerland/Germany), was studied at high temporal resolution for non-pollen palynomorphs (NPPs) within a calcareous gyttja sediment core from the deepest part of the lake. At the Nussbaumersee lakeshore, three pile-dwelling settlements have been excavated and dendrochronologically dated (to the Neolithic, 3840–3695 bc; late Early Bronze Age, 1580–1538 bc; and Late Bronze Age, 850–780 bc). The NPP…

    Here, we present results from the most comprehensive compilation of Holocene peat soil properties with associated carbon and nitrogen accumulation rates for northern peatlands. Our database consists of 268 peat cores from 215 sites located north of 45°N. It encompasses regions within which peat carbon data have only recently become available, such as the West Siberia Lowlands, the Hudson Bay Lowlands, Kamchatka in Far East Russia, and the Tibetan…

  • Bog burst in the eastern Netherlands triggered by the 2.8 kyr BP climate event

    Open AccessBas Van Geel, Henk Heijnis et al.ARTICLEThe Holocene2014Citada por: 3Referências: 9

    The nature and cause of the so-called 2.8 kyr BP event have been a subject of much debate. Peat sequences have provided much of the evidence for this event, but the process link between climate and peatland response is not well understood. Multiproxy, high-resolution analysis of a core from Bargerveen in the eastern Netherlands based on pollen, non-pollen palynomorphs, testate amoebae and geochemistry identified an abrupt shift from relatively dr…

  • Carbon accumulation in peat deposits from northern Sweden to northern Germany during the last millennium

    Open AccessMarjolein Van Der Linden, Monique MPD Heijmans et al.ARTICLEThe Holocene2014Citada por: 3Referências: 2

    Historic carbon accumulation rates in four bogs on a north to south transect from Sweden to Germany were calculated by using the bulk densities and carbon concentrations of 1-cm peat layers and a fine-resolution radiocarbon chronology. Carbon accumulation rates were compared to environmental data to explore the effects of climatic factors. Carbon accumulation rates in a period without clear human impact on the bog ecosystems ( c.ad 1700–ad 1800) …

  • Multiproxy study of the last meal of a mid-Holocene Oyogos Yar horse, Sakha Republic, Russia

    Open AccessBarbara Gravendeel, А В Протопопов et al.ARTICLEThe Holocene2014Citada por: 1Referências: 9

    The last meal of a horse that lived in the northern part of the Sakha Republic (Russia) c. 5400 years ago was studied using pollen, spores, botanical macroremains, lipid composition, and ancient DNA in order to reconstruct its components. Pollen of Poaceae was superabundant, but this may be because of over-representation as a consequence of grazed inflorescenses of grasses. We evaluate the paleo-environmental indicator value of the different meth…

  • Dating Recent Peat Accumulation in European Ombrotrophic Bogs

    Johannes Van Der Plicht, Dan Yeloff et al.ARTICLERadiocarbon2013Citada por: 5Referências: 50

    This study compares age estimates of recent peat deposits in 10 European ombrotrophic (precipitation-fed) bogs produced using the 14 C bomb peak, 210 Pb, 137 Cs, spheroidal carbonaceous particles (SCPs), and pollen. At 3 sites, the results of the different dating methods agree well. In 5 cores, there is a clear discrepancy between the 14 C bomb peak and 210 Pb age estimates. In the upper layers of the profiles, the age estimates of 14 C and 210 P…

    Open AccessKenneth F Rijsdijk, Jens Zinke et al.ARTICLEThe Holocene2011Citada por: 1Referências: 9

    In the light of the currently increasing drought frequency and water scarcity on oceanic islands, it is crucial for the conservation of threatened insular vertebrates to assess how they will be affected. A 4000 yr old fossil assemblage in the Mare Aux Songes (MAS), southwest Mauritius, Mascarene Islands, contains bones of 100 000+ individual vertebrates, dominated by two species of giant tortoises Cylindraspis triserrata and C. inepta, the dodo R…

  • Solar Influences on Climate

    Open AccessLesley J Gray, Jeremy Beer et al.ARTICLEReviews of Geophysics2010

    Understanding the influence of solar variability on the Earth's climate requires knowledge of solar variability, solar-terrestrial interactions, and the mechanisms determining the response of the Earth's climate system. We provide a summary of our current understanding in each of these three areas. Observations and mechanisms for the Sun's variability are described, including solar irradiance variations on both decadal and centennial time scales …
