  5. 3. Animals and Humans : Human-animal interaction in northern Sweden during the late glacial and postglacial time

    Author : Therese Ekholm; Sabine Sten; Carl-Gösta Ojala; Ola Magnell; Uppsala universitet; []
    Keywords : Mesolithic; fauna; radiocarbon dating; northern Sweden; calcined bones; pioneers; hunter-gatherers; zooarchaeology; lithic technology; taphonomy; 8.2 k BP cold event; prey.; Archaeology; Arkeologi;

    Abstract : When the last remnant of the Weichsel glacier melted in northern Sweden, around 7000 BC, pioneer settlers entered virgin land, following their prey, which in turn followed the vegetation dispersion. Some of the settlers derived from the east and the northeast and spread from the Russian taiga, through Finland and into northern Sweden, the study area for this thesis. READ MORE

  6. 4. Molecular ecology of marine mammals

    Author : Morten Tange Olsen; Per Palsbøll; Martine Bérubé; William “Bill” Amos; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Marine mammals; molecular ecology; life history; environmental change; phenotypic plasticity; SNPs; telomeres; molekylärgenetik; Molecular Genetics;

    Abstract : Marine mammals comprise a paraphyletic group of species whose current abundance and distribution has been greatly shaped by past environmental changes and anthropogenic impacts. This thesis describes molecular ecological approaches to answer questions regarding habitat requirements, genetic differentiation, and life-history trade-offs in three species of marine mammals.
