1178 P.-O. Cheptou and U. Dieckmann Self-fertilization in density-regulated populations



bred progeny is derived as a function of the underlying ecological parameters. Because of the inherent frequency dependence of selection on reproductive traits in densityregulated populations (Maynard Smith 1982; Morgan et al. 1997), we carry out an evolutionary invasion analysis within the framework of adaptive dynamics theory (Metz et al. 1992, 1996; Dieckmann 1997). For simplicity, the evolution of sel � ng rates is modelled phenotypically, which is a classical approach in models of evolutionary game theory (Maynard Smith 1982). On this basis, we derive expressions for the outcome of sel � ng evolution governed by inbreeding depression and the cost of outcrossing. The evolution of sel � ng is � rst considered under stable population dynamics before we extend our analysis to non-equilibrium population dynamics an
