  1. 1. 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

  2. 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.

  3. 3. Impact of southern Baltic sea-level changes on landscape development in the Verkeån River valley at Haväng, southern Sweden, during the early and mid Holocene

    University essay from Lunds universitet/Geologiska institutionen

    Author : Anette Nilsson Brunlid; [2018]
    Keywords : sea-level change; Littorina Sea; Baltic Sea; Ancylus Lake; environmental reconstruction; Holocene; Earth and Environmental Sciences;

    Abstract : In the Hanö bay off the coast at Haväng in SE Scania, southern Sweden, a submerged and well-preserved Mesolithic landscape is found, including remains of trees, river and lagoon sediments, and archaeological artefacts such as an antler pick axe and stationary fishing constructions. The landscape was formed during the Yoldia Sea (11,700-10,800 cal BP) and Initial Littorina Sea (9800-8500) low-water phases of the Baltic Basin. READ MORE

  4. 4. 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

  5. 5. 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.
