Table 2 Abundance (mean percent cover and SE) of the species found at Kringel at elevation zones 1 (between −10 cm and 20 cm of elevation, relative to chart datum), 2 (20–50 cm), 3 (50–80 cm), 4 (80–110 cm), 5 (110–140 cm), and 6 (140–170 cm)

From: An environmental stress model correctly predicts unimodal trends in overall species richness and diversity along intertidal elevation gradients
