  1. 6. Ecological connectivity in East African seascapes

    Författare :Charlotte Berkström; Nils Kautsky; Susan S. Bell; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; fish; functional group; food-web interactions; nursery; coral; seagrass; mangrove; landscape ecology; marin ekotoxikologi; Marine Ecotoxicology;

    Sammanfattning : Coral reefs, seagrass beds and mangroves constitute a complex mosaic of habitats referred to as the tropical seascape. Great gaps exist in the knowledge of how these systems are interconnected. This thesis sets out to examine ecological connectivity, i.e. LÄS MER

  3. 7. New methods of teaching? : refroming education in Lao PDR

    Författare :Kongsy Chounlamany; Bounchanh Khounphilaphanh; Britt-Marie Berge; Ann-Louise Silfver; Marianne Bloch; Umeå universitet; []
    Nyckelord :education; reform; new methods of teaching; student-centred education; gender; ethnicity; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; Education; pedagogik;

    Sammanfattning : This thesis is about the recent education reform in Laos as a global and a local process. When the economy was deteriorating in Lao People’s Democratic Republic (PDR), the so called New Economic Mechanism (NEM) was introduced and the country opened up for global donors and markets. This also had an effect on the education system. LÄS MER

  4. 8. Coevolution and molecular background of species interactions in geographic mosaics

    Författare :Xuyue Yang; Peter A. Hambäck; Michael R. Strand; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; transcriptomics; population genetics; insect immunology; parasitoid; genome assembly; natural selection; Ecology and Evolution; ekologi och evolution;

    Sammanfattning : In complex food webs, species often interact with each other indirectly through mediating species. As a result of geographic mosaic of coevolution, such interactions are often evolutionarily unstable and the traits governing the interaction sometimes vary over time. LÄS MER

  5. 9. Dynamics of seashore populations of Agrostis stolonifera, Festuca rubra and Poa irrigata

    Författare :Guðrún Á. Jónsdóttir; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Populationsekologi;

    Sammanfattning : The dynamics of tillers of natural populations of three cohabiting perennial grass species Agrostis stolonifera, Festuca rubra and Poa irrigata were studied for five years in a Baltic seashore meadow. A demographic approach based on numerical changes over time was used. LÄS MER

  7. 10. Genetic studies in early embryos with emphasis on preimplantation genetic diagnosis

    Författare :Erik Iwarsson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :chromosomal abnormality 1 embryo fluorescent in situ hybridisation FISH 1 in vitro fertilisation IVF 1 preimplantation genetic diagnosis PGD ;

    Sammanfattning : It has been estimated that as much as 70-80% of all human conceptions do not develop to term. A majority of clinically recognisable pregnancies, which are miscarried, contain chromosome abnormalities. However, data from very early embryo development are difficult to obtain. LÄS MER
