    Sammanfattning : Women's entrepreneurship is often presented as important for creating economic prosperity at the national level and is said to offer freedom, independence, and emancipation for women. The purpose of this study is to explore the conditions of women entrepreneurs who have different backgrounds in Sweden. LÄS MER

  3. 7. Tales of the flying earth: The effect of host flyways on the phylogeny of shorebird lice (Phthiraptera: Ischnocera)

    Författare :Daniel Gustafsson; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Parasite; Bird; Lice; Louse; Migration; Evolution; Ecology; Co-evolution; Lunaceps; Shorebirds; Carduiceps; Quadraceps; Revision; Phylogeny; Saemundssonia; Rallicolidae; Charadriiformes; Scolopacidae; Phthiraptera; Philopteridae; Ischnocera; Sandpiper; Flyways; Chewing Lice;

    Sammanfattning : On the wings, bodies, and heads of most birds there are lice. These lice spend their whole lives on their host, with the exception of the few lice that get the opportunity to transfer from one host to another, typically when the hosts come into physical contact with each other.

  4. 8. Evolutionary ecology of newts

    Författare :Jan C. Malmgren; Hanna Kokko; Örebro universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; evolution; adaptation; amphibians; salamanders; predation; migration; sexual dimorphism; sex differences; behaviour; conservation; Biology; Biologi; Biologi med ekologisk inriktning;

    Sammanfattning : Sexual dimorphism, predator avoidance and migratory behaviour are adaptive traits that show variation at the population and species level. Such features respond to the environment in the broad sense, that is, when both abiotic and biotic components are included. LÄS MER

  5. 9. Conifer Evolution, from Demography and Local Adaptation to Evolutionary Rates : Examples from the Picea genus

    Författare :Jun Chen; Martin Lascoux; Ulf Lagercrantz; Matt Olson; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Speciation; Demographics; clinal variation; convergent evolution; transcriptome; small regulatory RNA; Biologi med inriktning mot evolutionär funktionsgenomik; Biology with specialization in Evolutionary Functional Genomics; Biology with specialization in Evolutionary Genetics; Biologi med inriktning mot evolutionär genetik;

    Sammanfattning : Evolutionary process can be inferred at three different levels: the species level, the population level and the molecular level. In this thesis, I applied approaches at these three levels and aimed to get a comprehensive picture of conifer evolution, from speciation and demography to geographic variation and local adaptation, and then to the molecular evolution of proteins and small regulatory RNAs.

  7. 10. Epidemiology and population structure of Campylobacter jejuni and related organisms in wild birds

    Författare :Jonas Waldenström; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; epidemiology; Campylobacter lari; population structure; Helicobacter canadensis; Ecology; Parasitology human and animal ; Animal ecology; Djurekologi; Parasitologi människa och djur ; migration; Ekologi; wild birds; Sweden; Campylobacter jejuni;

    Sammanfattning : Campylobacter jejuni is one of the most common causes to bacterial gastroenteritis in the industrialised world. Also other species of the Campylobacter genus give rise to human infections. C. jejuni occurs in many different animal hosts and can be isolated from water sources. LÄS MER
