This within-clone movement of gametes is expected to reduce sexual fitness via mate limitation of male reproductive success and, in some cases, via the production of highly inbred (i.e., self-fertilized) offspring. However, clonality also results in the spatial expansion of the genetic individual (i.e., genet), and this should decrease distances gametes and sexually produced offspring must travel to avoid competing with other gametes and offspring from the same clone. The extent to which any negative effects of clonality on mating success might be offset by the positive effects of spatial expansion is poorly understood. Here, we develop spatially explicit models in which fitness was determined by the success of genets through their male and female sex functions. Our results indicate that clonality serves to increase sexual fitness when it is associated with the outward expansion of the genet. Our models further reveal that the main fitness benefit of clonal expansion might occur through the dispersal of offspring over a wider area compared with nonclonal phenotypes. We conclude that, instead of interfering with sexual reproduction, clonal expansion should often serve to enhance sexual fitness.</dcterms:abstract> <dcterms:title>Consequences of clonality for sexual fitness : Clonal expansion enhances fitness under spatially restricted dispersal</dcterms:title> <dc:language>eng</dc:language> <dc:creator>Van Drunen, Wendy E.</dc:creator> <dc:contributor>van Kleunen, Mark</dc:contributor> <bibo:uri rdf:resource="http://kops.uni-konstanz.de/handle/123456789/31813"/> <dc:creator>van Kleunen, Mark</dc:creator> <dc:contributor>Van Drunen, Wendy E.</dc:contributor> </rdf:Description> </rdf:RDF>
