Fig. 5From: Active eukaryotes in drinking water distribution systems of ground and surface waterworksa–e Boxplot of alpha-diversity Chao1 values in cold water within DWDSs A–E. Values are separated by location (1 to 3) and by template RNA/DNA in the drinking water distribution system. Statistical significance of the location (RNA + DNA): *P < 0.05; **P < 0.01; ***P < 0.001Back to article page
