Significant results (p < .05) are printed in bold, marginally significant results (p < .1) are printed in italic. a data are log transformed. https://doi.org/10.1371/journal.pone.0276789.t001 Fig 1. Treatment effects on Silene performance. Height (a, n = 80) and biomass (b, n = 78) responses of Silene latifolia to combinations of grazing, fertilization, ambient and future climate and light addition. The data are means ± SE. Note, that two transplants were not harvested for biomass determination because they were grazed to a few millimeters from the ground. https://doi.org/10.1371/journal.pone.0276789.g001 PLOS ONE
