  1. 1. Fire history in the hemiboreal and southern boreal zones of southern Sweden during 11000 years : Relationships with past vegetation composition and human activities and implications for biodiversity issues

    Författare :Qiao-Yu Cui; Marie-José Gaillard; Boris Vannière; Linnéuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fire history; land-use history; biodiversity; charcoal analysis; Landscape Reconstruction Algorithm LRA ; Holocene; Småland; Sweden; Paleoecology; Paleoekologi;

    Sammanfattning : This thesis studies fire history over the last 11 000 years (Holocene) in central Småland, southern Sweden, on the basis of palaeoecological analyses of peat sequences from three small bogs (Notteryd, Stavsåkra and Storasjö). The main objective is to gain insights into the long-term relationships between fire, climate, human-impact, other environmental factors and the history of biodiversity in the study region. LÄS MER

  4. 3. Pollen productivity estimates and pollen-based reconstructions of Holocene vegetation cover in Northern and temperate China for climate modelling

    Författare :Furong Li; Marie-José Gaillard; Mary E. Edwards; Linnéuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; climate; pollen-vegetation relationships; relative pollen productivity; REVEALS model; anthropogenic land-cover change; Holocene; China; Paleoecology; Paleoekologi;

    Sammanfattning : Model projections of future climate change require that coupled climate-vegetation models are developed and validated, i.e. these models should be able to reproduce past climate and vegetation change. Records of pollen deposited in lake bottoms and peat bogs can provide the information needed to validate these models. LÄS MER

  7. 5. Palaeoenvironments, palaeoecology and palaeobiogeography of Late Cretaceous (Campanian) faunas from the Kristianstad Basin, southern Sweden, with applications for science education

    Författare :Elisabeth Einarsson; Berggrundsgeologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; palaeoenvironments; palaeoecology; palaeobiogeography; Campanian; Kristianstad Basin; Teaching and Learning;

    Sammanfattning : This thesis is thematically divided into two sections: Part1 presents studies related to the palaeoenvironments,palaeoecology and palaeobiogeography of the LateCretaceous (Campanian) faunas from the KristianstadBasin of southern Sweden; Part 2 reports on applicationsof palaeontological research for science education inschools.Part 1 was based on personally conducted fieldworkand biostratigraphical analysis at various Santonian-Campanian localities throughout Skåne.
