“…As the organ for water uptake, roots, particularly fine roots, are presumably sensitive to precipitation changes. Syntheses and meta-analyses based on these precipitation manipulation experiments found that precipitation significantly related to multiple aspects of ecosystem function such as aboveground biomass and productivity (Wu et al, 2011;Wilcox et al, 2017), biomass allocation (Poorter & Nagel, 2000), and soil C pools (Zhou et al, 2016).
