From: Species richness and diversity across rocky intertidal elevation gradients in Helgoland: testing predictions from an environmental stress model

Fig. 3

Trends in species richness (mean ± SE) across a intertidal elevation (with data for the 3 shores combined; main effects) and b the 3 studied shores (with data for the 3 elevations combined; main effects). In each graph, significant differences between means are indicated by different letters (see “Results” for P values). The elevation × shore interaction was not significant (Table 2), so no simple effects were calculated
