    Sammanfattning : This thesis examines the use of various osseous raw materials in craft activities in the Mälaren region during the Middle Ages. Places studied are: Birka, Sigtuna, Nyköping, Strängnäs and Uppsala. The aim is to capture both chronological and spatial changes in the use of osseous raw materials. LÄS MER

  3. 2. Temporal and spatial variation in predation on roe deer fawns

    Författare :Jonas Nordström; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : This thesis deals with variation in mortality of roe deer fawns, over time and in space, caused by red fox and Eurasian lynx predation in a boreal landscape. The thesis considers historic and recent effects of vole population dynamics on red fox predation on roe deer fawns, using long term time series from Grimsö Wildlife Research Area. LÄS MER

  4. 3. Trophic resource use and partitioning in multispecies ungulate communities

    Författare :Robert Spitzer; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Over the past decades, ungulates across the northern hemisphere have been expanding in range and numbers. This has raised concerns about their impacts, particularly on shared resources with humans, e.g., timber trees. LÄS MER

  5. 4. Biochemical genetic variation, intraspecific genetic structure and postglacial evolution of select north European vertebrate species

    Författare :Ulf Gyllensten; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Evolution biologi ; Populationsgenetik;

    Sammanfattning : Analysis of the tempo and mode of intraspecific differentiation provides important information for understanding subspeciation, for construction of taxonomic hierarchies within a species and for management of genetic variation in natural populations.The present thesis describes the genetic structure of natural populations of willow grouse (Lagopus tagopus L.

  7. 5. Applying emerging genetic methods to wild model systems

    Författare :Ida-Maria Blåhed; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Genetic material is an invaluable source of information for assessments of wild populations. By using information derived from genetic markers, individuals can be identified and tracked over time, enabling studies of a wide range of behavioral, ecological, and evolutionary processes. LÄS MER
