Extended Data Fig. 8: Effects of four years of extreme drought on dominant and subordinate species cover and richness.
From: Contrasting drought sensitivity of Eurasian and North American grasslands
a, the absolute values for dominant species cover. b, subordinate species cover. c, dominant species richness. d, subordinate species richness. e, the response ratio for dominant species cover. f, subordinate species cover. g, dominant species richness. h, subordinate species richness. Values are mean ± s.e.m. In Eurasian grasslands, n = 36, and in North American grasslands, n = 60, for both the absolute values and response ratios of species cover and richness. Statistical significance of the absolute values between treatments is depicted as * (p < 0.05) and different uppercase and lowercase letters indicate significant differences in response ratio to extreme drought among treatment years for Eurasian and North American grasslands, respectively. The significances were assessed by Tukey’s HSD tests (two-sided).
