  2. 1. Adaptive divergence in fission yeast : From experimental evolution to evolutionary genomics

    Author : Sergio Ivan Tusso Gomez; Jochen B.W. Wolf; Simone Immler; Roger K. Butlin; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; adaptation; divergence; selection; experimental evolution; genomics; genome evolution; population genetics; fission yeast; phenotypic variation; Biology with specialization in Evolutionary Genetics; Biologi med inriktning mot evolutionär genetik;

    Abstract : How adaptation and population differentiation occur is fundamental to understand the origin of biodiversity. Work in speciation alongside the increased ease of generating genomic data have allowed the exploration of genomic changes relevant to adaptation. READ MORE

  4. 2. Phenotypic Processes Triggered by Biological Invasions

    Author : Philipp E Hirsch; Richard Svanbäck; Skúli Skúlason; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Resource polymorphism; phenotypic plasticity; phenotypic divergence; anti-predator responses; Perca fluviatilis; Rutilus rutilus; Dreissena polymorpha; Biology with specialization in Limnology; Biologi med inriktning mot limnologi;

    Abstract : Individuals within a single population can vary widely in their phenotype e.g. in their body shape. These differences are an important source of biodiversity and they can precede evolutionary divergence within a population. READ MORE

  5. 3. Migratory behaviour and adaptive divergence in life-history traits of pike (Esox lucius)

    Author : Petter Tibblin; Per Larsson; Anders Forsman; Asbjørn Vøllestad; Linnéuniversitetet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; conservation; evolution; homing; local adaptation; management; phenotypic variation; population divergence; selection; sympatric;

    Abstract : Population divergence shaped by natural selection is central to evolutionary ecology research and has been in focus since Darwin formulated “The origin of species”. Still, the process of adaptive divergence among sympatric populations is poorly understood. READ MORE

  6. 4. Intraspecific divergence and phenotypic plasticity in behavioural profiles of teleost fish

    Author : Johanna Axling; Svante Winberg; Johan Höjesjö; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; animal personality; phenotypic plasticity; Salmo salar; Danio rerio; activity; boldness; aggression.; Biology with specialization in Comparative Physiology; Biologi med inriktning mot jämförande fysiologi;

    Abstract : Behavioural differences between and within individuals can greatly affect the outcome of behavioural studies. In addition, behavioural interactions between individuals can compromise the health and welfare of captive fish. READ MORE

  7. 5. The Interplay Between Selection And Constraints On Adaptive Divergence And Phenotypic Evolution

    Author : Fabrice Eroukhmanoff; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Selection; Constraints; Adaptive Divergence; G-matrix; Gene Flow.; Speciation;

    Abstract : Under natural or sexual selection, individuals with advantageous traits or combinations of traits will be more successful than their peers at surviving and/or reproducing. Provided these traits are heritable, meaning that they have a genetic basis, the traits combinations which are selected for, will increase in frequency in the population. READ MORE
