Fig. 5From: Increased soil moisture aggravated the competitive effects of the invasive tree Rhus typhina on the native tree Cotinus coggygriaThe log response ratio (lnRR) of Rhus typhina and Cotinus coggygria under three water regimes. The lnRR was calculated as ln (total biomass of a target plant grown in monoculture/total biomass of a target plant grown in mixed culture). Data in the figure are mean ± SE (n = 5). Different letters denote significant differences (p ≤ 0.05) with Duncan’s methodBack to article page
