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

    Detta är en avhandling från Department of Biology, Lund University

    Författare :Josefin Madjidian; Lund University.; Lunds universitet.; [2011]
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

    Detta är en avhandling från Department of Biology, Lund University

    Författare :Thomas L Ewing; [2011]

Companies have increasingly realized that they do not need to create IPRs themselves to exploit them beneficially, which has been the conventional usage pattern. LÄS MER
