  1. 1. Holocene vegetation change and its correlates in fennoscandia

    University essay from Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Author : Raphaela Infanger; [2022-10-21]
    Keywords : Fennoscandia; Holocene; human impact; climate impact; vegetation change; fossil pollen;

    Abstract : Climatic and anthropogenic legacy has differently impacted vegetation and its community composition. To determine the extent and origin of changes across Fennoscandia, representative regions were defined that entailed sufficient spatial and temporal data. READ MORE

  3. 2. 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.

  4. 3. Vegetation responses to Late Glacial climate shifts as reflected in a high resolution pollen record from Blekinge, south-eastern Sweden, compared with responses of other climate proxies

    University essay from Lunds universitet/Geologiska institutionen

    Author : Artemis Karlatou-Charalampopoulou; [2016]
    Keywords : lake sediments; Blekinge; SE Sweden; Pleistocene-Holocene boundary; loss on ignition; pollen analysis; high time-resolution; time lags; Earth and Environmental Sciences;

    Abstract : Denna studie fokuserar på en nästan 1700 år lång sjösedimentsekvens från Hässeldala Port i centrala Blekinge, sydöstra Sverige. Den omfattar övergångsperioden mellan pleistocen och holocen, eller mer precist eventen GI-1a och GS-1 samt början av den holocena epoken i iskärnorna, vilket motsvarar de sydsvenska pollenzonerna sen allerød till tidig preboreal.

  5. 4. Ancient DNA from soils and sediments from the Krigstjärn area, northern Sweden : Preservation and detection of Holocene mammal sedaDNA

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

    Author : Anne van Woerkom; [2016]
    Keywords : ancient DNA; faunal reconstruction; palaeoecology; lake sediments; glacial vegetation;

    Abstract : Current knowledge of past vegetation and faunal diversity has been based on pollen and macrofossil analysis from lake sediments. The innovative method of sedimentary ancient DNA (sedaDNA) is a promising, complementary proxy to reconstruct information about past environments. READ MORE

  6. 5. A palaeoenvironmental study of a peat sequence from Iles Kerguelen (49°S, Indian Ocean) for the Last Deglaciation based on pollen analysis

    University essay from Lunds universitet/Geologiska institutionen

    Author : Victor Henao; [2015]
    Keywords : Earth and Environmental Sciences;

    Abstract : In recent years, the Southern Hemisphere (SH) and the vast Southern Ocean (SO) have gained awareness and importance within the scientific community in relation to global climate change and the global CO2 cycle, par-ticularly since the Last Glacial Maximum (LGM) and into the Holocene. It is believed that the Southern Hemi-sphere Westerlies (SHW) play a key role in regulating climate change in the mid-to-high latitudes of the SH, thus reconstructing the SHW latitudinal positioning since the LGM has been crucial.
