Formation of extensive fresh-water marshes along streams appears to have been brought about by general water-table changes controlled by the post glacial rise of sea level. As the sea continued to rise, marsh development proceeded inland and fine-grained organic sediments began to accumulate. By 6,000 years B.P. approximately 50% of Dismal Swamp area had been mantled by fine-grained peat deposits. From 6,000 to 3,500 B.P. peat accumulation continued, but at an appreciably lower rate. This corresponds both to the hypsithermal interval and to a distinct slackening in the rate of sea-level rise. By 3,500 B.P. peat had mantled virtually all of the interfluves and "islands" within the swamp. -

In Search of the Bølling-Oscillation: a New High Resolution Pollen Record
Vegetation History and Archaeobotany https://doi.org/10.1007/s00334-019-00736-3 ORIGINAL ARTICLE In search of the Bølling‑Oscillation: a new high resolution pollen record from the locus classicus Lake Bølling, Denmark Sascha Krüger1,2 · Martin Damrath3 Received: 27 November 2018 / Accepted: 28 May 2019 © The Author(s) 2019 Abstract In a paper from 1942 Johannes Iversen described a warm phase prior to the Allerød warming from lake Bølling in western Denmark and thereby extended the common classifcation of Lateglacial biostratigraphy. Iversen’s assumptions concerning the Bølling-Oscillation were based on sedimentological features and high Betula (birch) pollen values in two pollen samples prior to the onset of the Allerød warming. Questions regarding the nature of the Bølling warming later became a discussion due to the expansion of terms into diferent felds and especially with advances in palynology. To further refne the knowledge on the Bølling-Oscillation, Hartmut Usinger investigated the locus classicus in 1982. The method of pollen-size-frequency distribution was applied on birch pollen in order to distinguish between B. nana- and B. pubescens-type pollen, however, the results were never published and got lost over time. Therefore, these data are presented here and the method as described by Usinger (Pollenanalytische und stratigraphische Untersuchungen an zwei Spätglazial-Vorkommen in Schleswig-Holstein, 1975, Danm Geol Unders Årbog, 1977:5–29, 1978a, Pollen Spores 23:389–432, 1981b) is performed on the reassembled dataset again. In order to solve existing ambiguities in Lateglacial terminology, especially concerning the terms Bølling and Meiendorf, we used the data originally compiled by Usinger to discuss it against the background of the previous work by Iversen. -

White Master of Science Department of Geography September 2014 Title: Postglacial Vegetation Change in the Interior Temperate Rainforest of British Columbia The interior temperate rainforest of eastern British Columbia, Canada, supports dozens of species disjunct from their main coastal distribution, but the paleoecological history of this biogeographically unique area remains poorly studied. Specifically, the arrival time and migration route of the key rainforest tree species Tsuga heterophylla remains poorly understood. Sediment cores were obtained from two lakes occupying kame terraces on opposite sides of the upper Fraser River in east-central British Columbia. Pollen analysis indicates an early Holocene arrival time for this key species, much earlier than has previously been established and suggestive of a north-to-south migration route. Although the pollen records were broadly similar, minor differences occurred in the temporal zonation and pollen assemblages between sites. -

The Long-Term History of Temperate Broadleaves in Southern Sweden

Considering the present small area of the forest type, the habitat is of considerable interest for biodiversity, and knowledge about the history of temperate broadleaves is crucial for forest conservation and management. The main method used for studying past forest composition is pollen analysis, yet differences in pollen production and dispersal among taxa have hampered the estimation of historical cover of temperate broadleaves. By applying the Landscape Reconstruction Algorithm (LRA), a new model for translating pollen data into quantitative cover estimates, significantly improved understanding of the vegetation cover can be gained. The applications of the LRA to local and regional pollen data from southern Sweden carried out in this thesis show that in many areas, large cover of temperate broadleaves prevailed locally until rather recently, which is likely to be an important cause for the survival of the many threatened species associated with these tree taxa today, although in small and vulnerable populations. -

One Hundred Years of Quaternary Pollen Analysis 1916-2016
1 One hundred years of Quaternary pollen analysis 1916-2016 H John B Birks1,2 and Björn E Berglund3 1 Department of Biology and Bjerknes Centre for Climate Research, University of Bergen, PO Box 7803, N-5020 Bergen, Norway. email: [email protected] ORCiD: 0000-0002-5891-9859 2 Environmental Change Research Centre, University College London, Gower Street, London, WC1E 6BT, UK 3 Department of Geology, Quaternary Research, Lund University Sölvegatan 12, SE-22362 Lund, Sweden. email: [email protected] Abstract We review the history of Quaternary pollen analysis from 1916 to the present-day, with particular emphasis on methodological and conceptual developments and on the early pioneers of the subject. The history is divided into three phases – the pioneer phase 1916–1950, the building phase 1951–1973, and the mature phase 1974–present-day. We also explore relevant studies prior to Lennart von Post’s seminal lecture in 1916 in Kristiania (Oslo) in an attempt to trace how the idea of Quaternary pollen analysis with quantitative pollen counting and stratigraphical pollen diagrams developed. Keywords Concepts Gunnar Erdtman History Human impact Johs Iversen Knut Fægri Lennart von Post Methods Palaeoclimatology Pioneer, building, and mature phases Pioneers Pollen-representation studies Relative and radiocarbon dating Quaternary geology Quaternary pollen analysis Taphonomy 2 Introduction A two-day symposium entitled ‘Centenary (1916-2016) of Pollen Analysis and the Legacy of Lennart von Post’ at the Royal Swedish Academy of Sciences in Stockholm on 24–25 November 2016 celebrated 100 years of Quaternary pollen analysis (Richards 2017). The seminal lecture given by von Post in Kristiania (Oslo) in July 1916 is universally considered as the beginning of Quaternary pollen analysis as we know it.
