  1. 6. The Vegetational and Environmental Development of Lina Mire, Gotland from 6900-400 BC

    University essay from Stockholms universitet/Institutionen för naturgeografi

    Author : Nichola Strandberg; [2017]
    Keywords : Pollen; Lina Mire; Archaeology; Baltic; Human impacts;

    Abstract : Lina Mire, Gotland, is an area of archaeological significance and has a complex history of shoreline displacement. Archaeologists suspect that Lina Mire was once part of an important inland water system which connected the Littorina Sea with central Gotland. READ MORE

  3. 7. 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.

  4. 8. Is it possible to reconstruct local pre-sence of pine on bogs during the Ho-locene based on pollen data? : a study based on surface and stratigraphical samples from three bogs in southern Sweden

    University essay from Lunds universitet/Geologiska institutionen

    Author : Isabelle Timms Eliasson; [2014]
    Keywords : southern Sweden; vegetation cover; bog; Pinus; pollen; Earth and Environmental Sciences;

    Abstract : Horizons rich in subfossil stumps and roots of Scots pine (Pinus sylvestris) are frequently found in stratigraphies of northern European peatlands, providing clear evidence of Holocene periods with favourable conditions for bog-pine growth. The pines could only grow when bog-surface wetness was sufficiently low, and the presence of their remains is therefore a good indicator of past climatic conditions, mainly precipitation. READ MORE

  5. 9. 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

  6. 10. Early Holocene occurrence of thermophilous trees in the Storulvån valley : a study based on pollen analysis

    University essay from SLU/Dept. of Forest Ecology and Management

    Author : Daniella Andersson; [2008]
    Keywords : thermophilous; Storulvån; Holocene; pollen analysis;

    Abstract : Recent studies on vegetation history in the Swedish Scandes have altered the view on deglaciation and patterns of vegetation colonization. It is now suggested that the mountains were deglaciated earlier than previously thought and the climate being warm enough to allow thermophilous tree species to establish further north than generally thought.
