  1. 1. A palaeoecological study of the establishment of beech forest in Söderåsen National Park, southern Sweden

    University essay from Lunds universitet/Geologiska institutionen

    Author : Maja Damber; [2020]
    Keywords : Odensjön; southern Sweden; palaeoecology; pollen; macrofossils; lake sediments; Fagus sylvatica; Earth and Environmental Sciences;

    Abstract : Denna studie fokuserar på en sedimentsekvens som hämtats från Odensjön, i Söderåsens nationalpark i Skåne, södra Sverige. Den undersökta sekvensen, som täcker de översta 86 cm av sedimenten, är unik på grund av dess väldigt tydliga årsvarv, som har möjliggjort en precis datering (Hertzman in prep.). READ MORE

  3. 2. Evidence for birch forests and a highly productive environment near the margin of the Fennoscandian ice sheet in the Värriötunturit area, northeastern Finland

    University essay from Stockholms universitet/Institutionen för naturgeografi

    Author : Fredrik Bogren; [2019]
    Keywords : Early Holocene; productive ice-marginal environment; subarctic birch forests; plant macrofossils; pollen; palaeoenvironmental reconstructions; palaeoclimate reconstructions; Värriötunturit; Kuutsjärvi; northeastern Finland; northern Fennoscandia;

    Abstract : High-resolution records of early Holocene deposits are rare, and as a consequence reconstruction of terrestrial environments very soon after the deglaciation has often been difficult. In this study the palaeoenvironmental conditions of early Holocene (c. 10600-7500 cal. READ MORE

  4. 3. PLANT MIGRATION AT THE END OF THE WEICHSELIAN GLACIATION : Macrofossil evidence of early coniferous trees at two northern Swedish sites

    University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Author : Karan Zakrzewski-Sharma; [2019]
    Keywords : Scandinavia; Weichselian; plant migration; macrofossils; climate change;

    Abstract : Studies of vegetation history bring a new incentive to our understanding of plant survival and migration in arctic environments. For decades, environmental research was based on palynological data and these studies created a notion that tree species such as larch (Larix sibirica) and Scots pine (Pinus sylvestris) did not grow in northern Scandinavia at the end of Weichselian glaciation.

  5. 4. Cryptic refugia vs. Tabula Rasa: Boreal trees in glacial Fennoscandia : Plant growth during the Weichselian glaciation and the early Holocene in northern Europe

    University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Author : Anne van Woerkom; [2016]
    Keywords : boreal trees; Fennoscandia; cryptic refugia; Weichselian; glacial survival;

    Abstract : Recent studies applying innovative technologies, such as genetic analysis and carbon dating, contradict the palynological based assumption that Scots pine (Pinus sylvestris) and Norway spruce (Picea abies) vanished from Fennoscandia during the Last Glacial Maximum (c. 20.000 yrs BP) and re-colonized after the cold Younger Dryas (c. 12.

  6. 5. Holocene environmental changes as recorded in sediments from Kaggfjärden, southern archipelago of Stockholm, using diatom stratigraphy

    University essay from Institutionen för livsvetenskaper

    Author : Lena Ivarsson; [2011]
    Keywords : ;

    Abstract : Four sediment cores were sampled in Kaggfjärden, located in the southern archipelago of Stockholm. Two of the cores were analyzed with respect to the diatom record and lithology. Terrestrial macrofossils were dated using Carbon-14 dating. READ MORE
