  1. 1. "Socialistprästen" : H.F. Spak (1876-1926)

    Författare :Hans Falk; Sven-Eric Liedman; Stockholms universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; History of science and ideas; Idé- o lärdomshistoria; History of Ideas; idéhistoria;

    Sammanfattning : The present thesis is based on the life and works of H.F. Spak, known as ”the socialist priest”. He started out as a conservative priest, became a Social Democrat and was forced to resign from the church in 1911. LÄS MER

  3. 2. Imagining a Place in Nature: Using Evolution to Explain the Early Evolutionary Imagination in Literature

    Författare :Emelie Jonsson; Göteborgs universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; Victorian literature; Darwinism; evolutionary humanities; naturalistic cosmology; two cultures; mythology;

    Sammanfattning : After Charles Darwin published On the Origin of Species, Victorian literature overflowed with images of man’s new place in nature. Those images can be explained by modern research that builds on Darwin’s theory: the evolutionary social sciences and evolutionary literary theory. LÄS MER

  4. 3. On Speciation in Birds – Genomic Signatures across Space and Time

    Författare :Martin Stervander; MEMEG; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; colonization; islands; isolation; introgressive hybridization; sympatry; natural selection; bill morphology; coalescence-based analyses; DNA sequencing; birds; divergence; Speciation;

    Sammanfattning : The process of speciation is a cornerstone in evolutionary biology. In Darwin’s On the Origin of Species, he described how he imagined that a new species would evolve to fill an empty niche. This focus on ecology shifted with Mayr towards the importance of isolation, and for many decades the geographic modes of speciation were debated. LÄS MER

  5. 4. Evolutionary genetics and consequences of inbreeding in sand lizards (Lacerta agilis)

    Författare :Badreddine Bererhi; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Inbreeding; sand lizards; evolutionary genetics;

    Sammanfattning : Inbreeding is a well-known phenomenon in evolutionary and conservation biology. In the 19th century, Charles Darwin demonstrated the detrimental effects of inbreeding in plants, followed by over a century of extensive research including various animal and plant taxa. LÄS MER

  7. 5. Island biogeography and population divergence in the Skyros wall lizard

    Författare :Anna Runemark; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Podarcis gaigeae; inbreeding; predation release; polymorphism; island gigantism; the island rule; genetic drift; sexual selection; natural selection; island biology; Evolution;

    Sammanfattning : Islands are cradles for new biodiversity and provide natural laboratories for the study of population divergence. In my thesis, I investigated the role of different evolutionary processes in the population divergence in the Skyros wall lizard (Podarcis gaigeae), a species where islet populations have strongly diverged morphologies.
