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

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

    Abstract : 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. READ MORE

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

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

    Abstract : 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. READ MORE

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

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

    Abstract : 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. READ MORE

  6. 4. Island biogeography and population divergence in the Skyros wall lizard

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

    Abstract : 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.

  7. 5. Evolutionary dynamics of migration and breeding in wild birds: genetic architecture, sexual conflicts and evolutionary constraints

    Author : Maja Tarka; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; quantitative genetics; heritability; intralocus sexual conflict; antagonistic selection; QTL; G-matrix; wing length; arrival date; migration; geolocator; bird; Acrocephalus arundinaceus;

    Abstract : Our knowledge of the evolutionary potential of traits involved in different selective episodes, especially in natural populations, is still limited. This is true for questions such as the genetic basis and inheritance of traits, how natural and sexual selection acts on them, and how selective conflicts influence the evolutionary response to selection.
