Figure 1: Scopelophila catatactae and soil collected within the copper mine. Bar plots (mean + standard deviation with 3 replicates) of the total concentrations of Cu and Cd in soil (A, D) and plants of (B, E) where numbers inside the bars represent mean concentrations (µg g-1). Boxplots of the relative concentrations of Cu and Cd in moss samples (C, F) (n=12; % by weight). Panels G, H, and I depict the morphological measurements (plant length, leaf length, and leaf width in mm) performed in n=50 plants from each of the populations of S. cataractae collected in the field. Black stars inside the boxplots represent mean values. Letters inside the graph boxes represent the results of the multiple pairwise comparisons, with means sharing a letter not differing significantly. Green and red color represent populations sampled at the edges and the center of the mine respectively.
Figure 2: Scopelophila catatactae response to Cu and Cd treatment. Bar plots (mean µg g-1 indicated + standard deviation with 3 replicates) of the total concentrations of Cu in control and Cu-treated (A), and of Cd in control and Cd-treated (D) plants of S. catatactae cultured in the laboratory. Boxplots of the relative concentrations (n=12; weight %) of Cu in leaves and stems of control and Cu-treated plants (B, C respectively), and of Cd in leaves and stems of control and Cd-treated plants (E, F respectively). Black stars inside the boxplots represent mean values. Letters inside the graph boxes represent the results of the multiple pairwise comparisons, with means sharing a letter do not differing significantly. Green and red color represent populations sampled at the edges and the center of the mine respectively.
Figure 3: Scopelophila catatactae response to Cu and Cd treatment. Boxplots (n = 10) of plant length, leaf length, and leaf width (mm) in control and Cu-treated (A, B, C), and in control and Cd-treated (E, F, G) plants of S. catatactae cultured in the laboratory. Black stars inside the boxplots represent mean values. Bar plots (mean µM indicated ± standard deviation with 3 replicates except for controls whose n=2 for Sc3 and Sc4 and n=1 for Sc1) of the concentration of malondialdehyde (MDA) in control and Cu-treated (D), and in control and Cd-treated (H) plants. Letters inside the graph boxes represent the results of the multiple pairwise comparisons, with means sharing a letter not differing significantly. Green and red colors represent populations sampled at the edges and the center of the mine respectively.
Figure 4: Ceratodon purpureus response to Cu and Cd treatment. Bar plots (mean µg g-1 indicated + standard deviation with 2 replicates except for Cp1_Cd with n=1) of the total concentrations of Cu in control and Cu-treated (A) and in control and Cd-treated (B) plants of C. purpureus cultured in the laboratory. Boxplots of the relative concentrations (n=10; by weight %) and of the protonemal growth (mm2; n=35) in control and Cu-treated (B and C) and in control and Cd-treated (F and G) plants. Bar plots (mean µM indicated + standard deviation with 10 replicates) of the concentration of malondialdehyde (MDA) in control and Cu-treated (D) and in control and Cd-treated (H) plants. Black stars inside the boxplots represent mean values. Letters inside the graph boxes represent the results of the multiple pairwise comparisons, with means sharing a letter not differing significantly. Green and red color represent control and treated samples respectively.
