(a) Plant biomass (g m⁻²) of Hyptis suaveolens as axis Y1 and herbaceous species richness as axis Y2, and (b) species richness and alpha-diversity of native and non-native plant species in response to two light levels (sun, 842–1072 µmol m^–2 s⁻¹ and shade, 253–341 µmol m^–2 s⁻¹) in Vindhyan highlands suggesting enhanced light-mediated dominance of H. suaveolens and reduction of native and non-native herbaceous diversity
