From: Species richness both impedes and promotes alien plant invasions in the Brazilian Cerrado
Root phosphatase (PME) activity of common Cerrado plant species, as well as soil PME activity, in relation to species richness of the plant community. (a) PME activity in the soil, and (b)–(i), root PME activity of nine common plant species, in relation to species richness of the vegetation (number of plant species in 4-m2). Root and soil samples were collected in 38 sites in the Brazilian Cerrado (five nature reserves in two regions, see Suppl. Figure 1). Only significant (p < 0.05) regressions are drawn. †Could not be identified to species level.
