  1. 1. Ömse sidor om vägen : Allén och landskapet i Skåne 1700-1900

    Författare :Patrik Olsson; Institutionen för kulturgeografi och ekonomisk geografi; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Avenue; tree-lined road; landscape; aesthetics; historical geography; Scania.;

    Sammanfattning : This thesis is about avenues (tree-lined roads – in Swedish alléer). Avenues are a characteristic landscape element in many parts of Scania. This is an object created by man with a clear visual effect in the landscape. The avenue is also something which is both nature and culture, a man-made object from nature. LÄS MER

  3. 2. Small biotopes in agricultural landscapes: importance for vascular plants and effects of management

    Författare :Therese Irminger Street; Biodiversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Small biotopes; incidental habitat; vascular plants; woody vegetation; grassland species; resource provisioning; species richness; habitat specificity; non-crop habitat; landscape complexity; heterogeneity; local management; agri-environment scheme;

    Sammanfattning : As a consequence of agricultural intensification, large areas of non-crop habitat have been lost and farmland biodiversity has declined. Previous studies have shown that the extent of non-crop habitat influences farmland biodiversity, but the relative importance of different habitat types is less well known and the contribution of small incidental habitats to landscape-scale species richness is not fully understood.

  4. 3. Ground beetle dynamics in intensively managed agricultural landscapes

    Författare :Erkki Palmu; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Carabidae; species richness; species diversity; functional traits; body size; emergence; dispersal; stable isotopes; deuterium; oxygen; crop diversification; landscape heterogeneity; agricultural management;

    Sammanfattning : In this thesis I have focused on studying dynamics of ground beetle assemblages in intensively managed agricultural landscapes. By definition, the land cover of these landscapes is dominated by annually tilled farmland, comprising a range of different crop types, in the context of the southern Swedish province of Scania mostly winter wheat, spring barley, winter rapeseed, and sugar beets.

  5. 4. Middle and Upper Ordovician graptolites, trilobites, and biostratigraphy of Scania and Jämtland, Sweden

    Författare :Christian Pålsson; Berggrundsgeologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; physical geography; Geology; Sweden; Jämtland; Scania Skåne ; Upper Ordovician; Middle Ordovician; palaeoecology; biostratigraphy; lithostratigraphy; Graptolites; trilobites; Geologi; fysisk geografi; Palaeontology; Paleontologi;

    Sammanfattning : Graptolites and some trilobites from Middle–Upper Ordovician siliciclastic and calcareous rocks in Scania (Skåne), southern Sweden, and Jämtland, central Sweden, are described and discussed. Their stratigraphic distribution is discussed on the basis of new and old collections from outcrops and drill cores. LÄS MER

  7. 5. Cretaceous dinoflagellate cyst stratigraphy of the Höllviken 1 well, Scania, Southern Sweden

    Författare :Helena Westin; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The main aim of this thesis was to develop an improved biostratigraphical subdivision for part of the Lower and Upper Cretaceous section (Albian to Santonian) of Scania, Southern Sweden. Earlier attempts at biostratigraphic zonation within the sequence Cenomanian to Coniacian based on other micro- and macrofossils have proven difficult due to an impoverished fauna. LÄS MER
