Geometric mean fitness is maximized by an intermediate degree of diversification in seed germination timing. Geometric mean fitness is shown on the two y-axes: daily rate of seedling survival and geometric mean fitness relative to the fittest strategy over a 30-day period. Diversification strategies are reported as the standard deviation of the mean time to germination (days). Error bars indicate the standard error of geometric mean fitness estimates, and the solid line is the best-fit second-degree polynomial. The dotted line and grey area indicate observed germination variation (±s.d.) expressed within naturally inbred genotypes of L. inflata (Simons & Johnston 2006).
