  1. 1. 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

  2. 2. Sexual conflict and selection on pistil and pollen traits

    Author : Josefin Madjidian; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Antagonistic trait; Collinsia heterophylla; delayed stigma receptivity; direct cost; first-donor advantage; gender bias; heritability; indirect benefit; mate choice; mixed-mating system; paternal diversity; pollen competition; pollen deposition; pollen load size; pollen tube growth rate; self-compatibility; semantics; sexual conflict; sexual selection; sexually antagonistic co-evolution;

    Abstract : The incidence of sexual selection in plants is today acknowledged, however, just as in animals, evolution and maintenance of mate choice is gravely underexplored. Moreover, the potential for sexual conflicts to occur in plants has only been assessed empirically to a very limited degree. READ MORE

    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Bioteknik; Biotechnology; carbohydrate binding module; binding specificity; selection; combinatorial library; scaffold; protein engineering;

    Abstract : The growing field of biotechnology is in constant need of proteins that can function as recognition tools for separational, analytical and therapeutic purposes. Different molecular engineering approaches are applied on natural proteins in order to create variants with desired properties. READ MORE

  5. 5. Selection and moral hazard in health insurance : taking contract theory to the data

    Author : E Grönqvist; Handelshögskolan i Stockholm; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;
