Fig. 1From: Drought of early time in growing season decreases community aboveground biomass, but increases belowground biomass in a desert steppeEffects of extreme drought (CONT, control; − 66%, reduce 66% in rainfall from May to August; − 60 Days, reduce 100% in rainfall from June to July) on plant community characteristics of desert steppe during the treatment years (2015–2018). AGB aboveground plant biomass, BGB belowground root biomass. Variables are shown as mean ± SE (n = 6). Different lowercase letters indicate significant differences between years for the same treatments in p < 0.05. Statistical significance of drought effect in each year is depicted as **p < 0.0 1 and *p < 0.05Back to article page
