  1. 21. Bebyggelsens mångfald. En studie av södra Hallands järnåldersgårdar baserad på arkeologiska och historiska källor

    Författare :Lennart Carlie; Arkeologi; []
    Nyckelord :HUMANIORA; HUMANITIES; local variation.; agrarian economy; settlement structure; byres; houses; farms; graves; Halland; Iron age; Archaeology; Arkeologi;

    Sammanfattning : The aim of the dissertation is to elucidate Iron Age settlement in southern Halland from two angles: (1) the evidence of antiquities (graves), ground finds of metal and rock, and place-names; (2) the information conveyed by investigations in settlement archaeology. The combined study of graves, ground finds, and place-names shows that the image of southern Halland in the Iron Age differs depending on which category is analysed. LÄS MER

  3. 22. Protecting food with poison : Exploring ecotoxicity of agrochemicals and pharmaceuticals

    Författare :Oskar Nyberg; Michael Tedengren; Peter Fantke; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; LCA; ecotoxicology; uncertainty; antibiotics; aquaculture; pesticides; Ecotoxicology; ekotoxikologi;

    Sammanfattning : Chemicals are being emitted into the environment through human activities, such as agriculture or animal husbandry. Emissions can either occur intentionally, as pesticide application of crops, or inadvertently, such as pharmaceutical residues in wastewater effluents. LÄS MER

  4. 23. Effects of farmland heterogeneity at multiple spatial and temporal scales on house sparrow (Passer domesticus) population ecology

    Författare :Maria von Post; Biodiversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Farmland heterogeneity; house sparrow; agricultural intensification; farm specialisation; landscape complementation; resource separation; population limitation;

    Sammanfattning : Strong declines of European farmland birds in recent decades are assumed to be caused by decreased food availability resulting from agricultural intensification and concomitant loss of farmland heterogeneity. One of the species suffering particularly strong declines in NW European countries is the house sparrow. LÄS MER

  5. 24. Att stå på egna ben

    Författare :Bo Friman; Arkeologi; []
    Nyckelord :HUMANIORA; HUMANITIES; central functions; individual; collective; egalitarian; elite; pit-system; long-house; farm; village; manifestation; ancestor cult; possession; social bonds; Malmö; Mellanbyn; Early Iron Age;

    Sammanfattning : The dissertation can be divided into two parts, the first of which is a detailed analysis of three excavations concerning Mellanbyn in southern Malmö. In the second part I study the more general development of society, relating Mellanbyn to the surrounding area as well as to the region as a whole during Late Bronze Age and the Early Iron Age.

  7. 25. Pollinators and Insect Pollination in Changing Agricultural Landscapes

    Författare :Lina Herbertsson; Miljövetenskap; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; pollinators; pollination; agri-environment schemes; beekeeping; oilseed rape; sown flower strips; agri-environment measures;

    Sammanfattning : Agricultural intensification and associated loss of semi-natural grasslands, has resulted in reduced landscape heterogeneity. A concomitant loss of forage and nest sites for pollinating insects has driven declines across several pollinator taxa. LÄS MER
