We found that vertical profiles of individual species in a montane grassland varied considerably, from species with most root biomass concentrated in the uppermost (<2 cm) soil layer, through species with uniform vertical distribution, to a species with roots predominantly below 8 cm. Species at the fast end of the plant economy spectrum were more likely to place their roots in the uppermost layers. While below-ground and above-ground biomasses of most species were higher in the plots where the dominant species, Festuca rubra, had been removed, species rooting patterns did not change in response to the removal. The interspecific differences in vertical profiles were thus due to species’ innate differences, not to plastic responses to the presence of the dominant species. The findings imply that vertical root differentiation in the field is strong and can contribute to niche differentiation. The absence of the plastic response in the field is likely to be due to a fairly homogeneous distribution of nutrients in the soil and to the predominantly symmetric nature of below-ground competition.
