Comparison of log10 daily cellulose decomposition rates (KD) for rivers in glacierized mountain regions (0–85% catchment glacier cover) and rivers representing 11 other biomes. The KD values indicate the mean daily decomposition rates of the cellulose fabric in each river ecosystem (grey open circles). In the box plots, the centre lines represent the medians, the box limits represent the interquartile ranges, the whiskers represent the quartiles plus 1.5× the interquartile range and grey circles represent outlying values.
