  1. 1. Late Cenozoic Geoarchives from Lake Baikal, Siberia

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Tomasz Sapota; Uppsala universitet.; [2004]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Quaternary geology; Lake Baikal; Be-10 isotope; chronology; paleoclimate; tectonics; geomagnetic field; cosmic rays; Kvartärgeologi; NATURAL SCIENCES Earth sciences Exogenous earth sciences Quaternary geology; NATURVETENSKAP Geovetenskap Exogen geovetenskap Kvartärgeologi;

    Abstract : Three long sediment cores (BDP-98 – 600 m, BDP-96 – 200 m and BDP-93 – 100 m) drilled in Lake Baikal (Siberia) have been studied with the aims of establishing an absolute chronology and reconstructing paleoclimatic and paleoenvironmental changes in the region. The location of the lake at relatively high latitude and continental interior and a thick continuous sedimentary archive that developed in a rift system tectonic setting provide unique material for this investigation.

  2. 2. Sediment transport from source to sink in the Lake Baikal basin Impacts of hydroclimatic change and mining

    University dissertation from Stockholm : Department of Physical Geography, Stockholm University

    Author : Jan Pietroń; Stockholms universitet.; [2017]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; sediment transport; human impact; hydroclimatic change; surface mining; metal-enriched sediment; Lake Baikal; the Selenga River; the Selenga Delta; naturgeografi; Physical Geography;

    Abstract : Different magnitude, intensity and timing of precipitation can impact runoff, hillslope erosion and transport of sediment along river channels.  Human activities, such as dam construction and surface mining can also considerably influence transport of sediment and sediment-bound contaminants.

  3. 3. Hydrological spreading of metal pollution and wetlands as nature-based solutions

    University dissertation from Stockholm : Department of Physical Geography, Stockholm University

    Author : Josefin Thorslund; Stockholms universitet.; [2017]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physical Geography; naturgeografi;

    Abstract : The quality of the Earth’s water resources have deteriorated due to human impacts. A key scientific challenge is to understand, quantify and predict the water-borne spreading of pollutants at relevant scales for freshwater management and water quality restoration programs. READ MORE

  4. 4. Phylogeographic Structure and Genetic Variation in Formica Ants

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Anna Goropashnaya; Uppsala universitet.; [2003]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Genetics; Formica ants; phylogeography; phylogeny; Pleistocene refugia; population expansion; social organization; Genetik; MEDICINE Dermatology and venerology; clinical genetics; internal medicine Clinical genetics; MEDICIN Dermatologi och venerologi; klinisk genetik; invärtesmedicin Klinisk genetik;

    Abstract : The aim of this thesis is to study phylogeny, species-wide phylogeography and genetic diversity in Formica ants across Eurasia in connection with the history of biotic responses to Quaternary environmental changes.The mitochondrial DNA phylogeny of Palaearctic Formica species supported the subgeneric grouping based on morphological similarity.
