Nof: number of offspring with a father assigned (%). pi: pollen immigration. Nf: number of different fathers assigned. Ngp: Number of genotyped parents. Nf/Ngp (%). Nof/Nf: mean number of offspring per father (standard deviation (SD)). (see Fig. 2: male reproductive success). Ne: effective number of fathers (1/Σ(fi 2), where fi is the relative reproductive success of each father).
