Fig. 2. The population stage structure of four species and one subspecies of an endemic Diellia family in the Hawaiian archipelago. Dark grey parts of bars represent a relative number of sporeling stage, light grey parts represent the premature stage, and open parts of bars represent a proportion of the mature stage in the population. Plus signs indicate significantly higher proportions and minus signs indicate significantly lower proportions than predicted by the loglinear model (Freeman Tukey deviation test, p < 0.05).
