Effect of altered precipitation regimes on seed banks of a calcareous grassland after 14 years of precipitation shifts at Buxton. a Number of seeds. b Number of species. The long-term summer drought reduced the total seed abundance and species richness. Across all the treatments, the number of seeds a and species b declined with increasing soil sample depth. The figure shows the scatter plots with the fitted curves
