  1. 1. Fishing for ways to thrive : Integrating zooarchaeology to understand subsistence strategies and their implications among Early and Middle Mesolithic southern Scandinavian foragers

    Nyckelord :HUMANIORA; HUMANITIES; Early Holocene; Mesolithic; Palaeodiet; Zooarchaeology; Scandinavia; Subsistence; Fish; Forager;

    Sammanfattning : The purpose of this thesis is to evaluate and deduce the varied lifeways of Early Holocene foragers in southern Scandinavia. By taking an interdisciplinary approach, zooarchaeological data have been applied to the study of different aspects of Early and Middle Mesolithic subsistence, in order to frame a discussion concerning our current understanding of culture and life in early north European societies.

  4. 3. Predator-prey interactions of raptors in an arctic environment

    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ecology of raptors; Terrestrial; freshwater and marine ecology; Terrestisk; limnisk och marin ekologi;

    Sammanfattning : This thesis concerns the predator-prey interactions of three raptor species in a Swedish arctic community: the gyrfalcon (Falco rusticolus), the rough-legged buzzard (Buteo lagopus) and the golden eagle (Aquila chrysaetos). The gyrfalcon behaved like a highly specialised ptarmigan (Lagopus spp.) predator. LÄS MER
