Fig. 2From: Adaptive divergence in shell morphology in an ongoing gastropod radiation from Lake MalawiFecundity of morphospecies during the common garden experiment. Fecundity represents the number of offspring (mean ± standard error) generated by morphospecies averaged over the F1 and F2 generations. Statistically significant differences are indicated with asterisks (0.05 > * > 0.01 > ** > 0.001)Back to article page
